The present disclosure relates to a component mounting system equipped with a mounting apparatus that obtains a component loading board with components loaded on a board.
Conventionally, a component mounting system has been known that is equipped with a mounting apparatus that obtains a component loading board by loading electronic components (hereinafter simply referred to as “component”) on a board such as a printed circuit board. In this kind of component mounting system, the mounting apparatus includes a feeder that executes a component supply process to supply the component, a suction nozzle that executes a component suction process to suck the component supplied by the feeder, and a loading head that executes a component loading process to load the component on the board. The loading head executes the component loading process on each of a plurality of target loading positions that is set in advance on the board.
In the component loading process of the loading head, a position offset may occur between the actual suction position of the component by the suction nozzle (actual suction position) and the target suction position. Such a position offset of the suction position can be a generating factor for the position offset of the actual component loading position (actual loading position) with respect to the target loading position on the board. If the position offset of the actual component loading position occurs on the board, this will affect the quality of the component loading board obtained by the mounting apparatus.
Japanese Patent Application Laid-Open No. 2001-223499 discloses a technique for increasing the positional accuracy of the actual component loading position on the board. In the technique disclosed in Japanese Patent Application Laid-Open No. 2001-223499, a loading head (head unit) that sucks and holds a component with a suction nozzle (jig) captures and recognizes an image of the component while at a standstill at a target loading position (mounting position) on a board. By this image recognition, the positional difference between the central position of the component sucked and held by the suction nozzle and the target loading position is obtained. Then, using the positional difference, calibration of the mounting apparatus is executed for increasing the positional accuracy of the actual component loading position on the board.
Meanwhile, due to aged deterioration of the suction nozzle or the like, the position offset of the actual component suction position may grow beyond an allowable range. In this case, as in the technique disclosed in Japanese Patent Application Laid-Open No. 2001-223499, even if the mounting apparatus is calibrated based on the positional difference between the central position of the component sucked and held by the suction nozzle and the target loading position, there is a possibility that defects of the position offset of the actual component loading position on the board cannot be solved. Since it is difficult for the technique disclosed in Japanese Patent Application Laid-Open No. 2001-223499 to identify the generating factor for the position offset of the actual component suction position by the suction nozzle, it is difficult to take appropriate measures to solve the defects of the position offset of the actual component loading position on the board.
The present disclosure has been made in view of such circumstances, and provides a component mounting system that can check the generating status of the position offset of the component suction position by the suction nozzle and identify the generating factor for the position offset.
A component mounting system according to one aspect of the present disclosure includes a mounting apparatus including a feeder configured to execute a component supply process of supplying a component and a loading head including a suction nozzle that executes a component suction process of sucking the component to obtain a component loading board by executing a component loading process of loading the component sucked by the suction nozzle on a board: and a management device connected to the mounting apparatus to allow data communication. The management device includes a management communication unit configured to acquire, from the mounting apparatus, suction position offset data indicating an offset amount of a suction position of the component with respect to the suction nozzle in the component suction process, various pieces of parameter information to identify each of the component, the feeder, the suction nozzle, and the loading head used in each process of the component supply process, the component suction process, and the component loading process, and various processing state images each indicating an image of a processing state of each of the processes. The management device further includes a management storage unit configured to accumulate and store management data in which the suction position offset data, the various pieces of parameter information, and the various processing state images are associated with each other: a management display unit configured to display information on the management data: a management operation unit into which a command regarding a display mode of the management display unit is input: and a management control unit configured to control the management display unit in response to the command input into the management operation unit. The management control unit controls the management display unit such that, when a command to select one piece of parameter information from the various pieces of parameter information is input via the management operation unit, suction position offset distribution indicating distribution of a data group of the suction position offset data focusing on the one piece of parameter information is displayed. The management control unit controls the management display unit such that, when a command to select one or a plurality of the specific suction position offset data from the data group of the suction position offset distribution is input via the management operation unit with the suction position offset distribution displayed in the management display unit, the various processing state images corresponding to the specific suction position offset data are displayed simultaneously with the suction position offset distribution.

The mounting communication unit 40 is an interface for executing data communication with the management device 16, and has a function of outputting various data and information to the management device 16. The mounting control unit 4 controls the component loading process of the mounting apparatus body 2 and the like according to board data D25 stored in the mounting storage unit 40M and controls the data communication of the mounting communication unit 40.
The mounting apparatus body 2 includes a body frame 21, a conveyor 23, component supply units 24, a head unit 25, and a board support unit 28.
The body frame 21 is a structure on which respective parts that constitute the mounting apparatus body 2 are disposed, and is formed in a substantially rectangular shape in plan view when viewed from a direction orthogonal to both the X-axis direction and the Y-axis direction (perpendicular direction). The conveyor 23 extends in the X-axis direction and is disposed on the body frame 21. The conveyor 23 conveys the pattern forming board PP in the X-axis direction. Positioning of the pattern forming board PP conveyed on the conveyor 23 is determined by the board support unit 28 at a predetermined work position (component loading position where a component is loaded on the pattern forming board PP). The board support unit 28 determines positioning of the pattern forming board PP on the conveyor 23 by supporting the pattern forming board PP from below.
The component supply units 24 are disposed in regions at both ends of the body frame 21 in the Y-axis direction, with the conveyor 23 interposed therebetween. Each of the component supply units 24 is a region installed in the body frame 21 with a plurality of feeders 24F installed in parallel, and the set position of each feeder 24F is divided for each component to be held by loading heads 251 provided in the head unit 25 to be described later. Each of the feeders 24F is detachably installed in the component supply unit 24. The feeder 24F is a device that executes a component supply process to supply the component. The feeder 24F is not particularly limited as long as the feeder can hold a plurality of components and supply the held components to predetermined component supply positions set in the feeder, and is, for example, a tape feeder. The tape feeder is a feeder including a reel on which a component storage tape that stores the component at predetermined intervals is wound, and configured to supply the component by feeding the component storage tape from the reel.
The head unit 25 is held by a moving frame 27. A fixed rail 261 extending in the Y-axis direction and a ball screw shaft 262 rotationally driven by a Y-axis servomotor 263 are disposed on the body frame 21.

That is, the head unit 25 is movable in the Y-axis direction as the moving frame 27 moves, and is movable in the X-axis direction along the moving frame 27. The head unit 25 is movable between the component supply unit 24 and the pattern forming board PP supported by the board support unit 28.

Each loading head 251 can ascend and descend along the Z-axis direction between a suckable position where the suction nozzle 2511 can suck and hold the component and a retracted position above the suckable position. That is, when the suction nozzle 2511 sucks and holds the component, each loading head 251 descends from the retracted position toward the suckable position, and sucks and holds the component at the suckable position. Meanwhile, each loading head 251 after sucking and holding the component ascends from the suckable position toward the retracted position. Furthermore, each loading head 251 can ascend and descend along the Z-axis direction between a loadable position where the component sucked and held by the suction nozzle 2511 can be loaded at the predetermined target loading position on the pattern forming board PP, and the retracted position.

The third image capturing unit 33 is, for example, an image capturing camera disposed in the head unit 25 and including a CMOS or CCD image capturing element or the like. To recognize various marks affixed to an upper surface of the pattern forming board PP supported by the board support unit 28 while each loading head 251 is executing the component loading process, the third image capturing unit 33 captures an image of the marks from above. By recognizing the marks on the pattern forming board PP by the third image capturing unit 33, the position offset amount with respect to origin coordinates of the pattern forming board PP is detected.

The management storage unit 164 accumulates and stores management data DM in which the suction position offset data D1, the parameter information D2, the suction level data D3, the suction state data D4, the loading position offset data D5, the pattern board image G1, the processing state image G2, the loading board image G3, and the reflow board image G4 are associated with each other.
The management display unit 162 includes, for example, a liquid crystal display and the like. The management display unit 162 displays information on the management data DM stored in the management storage unit 164. The display operation of the management display unit 162 is controlled by the management control unit 165.
The management operation unit 163 includes a keyboard, a mouse, a touch panel, or the like provided in the management display unit 162. The management operation unit 163 receives input operations of various commands regarding the display mode of the management display unit 162 by the operator.
The management control unit 165 controls the management display unit 162 according to the command input into the management operation unit 163.
When a suction offset display command to display a position offset status of the component suction position with respect to the suction nozzle 2511 is input via the management operation unit 163, the management control unit 165 causes the management display unit 162 to display a display screen DS1 as shown in
The operator can visually check the generating status of the position offset of the actual component suction position by the suction nozzle 2511 based on the suction position offset distribution AD displayed in the management display unit 162.
At this time, the management control unit 165 may control the management display unit 162 such that suction position offset statistical information AST indicating statistics of the data group including each suction position offset data D1 is displayed simultaneously with the suction position offset distribution AD. The suction position offset statistical information AST includes information such as the average of position offset amount, variance and standard deviation (3σ) that are indicators of the magnitude of data dispersion, the maximum and minimum position offset amounts, and the like for the data group including each suction position offset data D1. Such suction position offset statistical information AST may be associated with information such as the upper and lower limits of the allowable range of the suction position offset amount, and CP and CPK, which are process capability indexes.
The management control unit 165 controls the management display unit 162 such that a date selection region B1, a Line selection region B2, a component selection region B3, a head selection region B4, a nozzle selection region B5, and a feeder selection region B6 that allow input operations via the management operation unit 163 are set on the display screen DS1.
The operator can select the acquisition date or acquisition period by the data calculation unit 46 of the mounting control unit 4 for each suction position offset data D1 that constitutes the suction position offset distribution AD by operating the date selection region B1 by using the management operation unit 163. For example, when a predetermined date or period is selected by an input operation on the date selection region B1, the management control unit 165 causes the management display unit 162 to display the suction position offset distribution AD indicating distribution of the data group including each suction position offset data D1 acquired by the data calculation unit 46 of the mounting control unit 4 on the predetermined date or predetermined period.
The operator can select the mounting apparatus 12 that is the output source of each suction position offset data D1 that constitutes the suction position offset distribution AD, and the like by using the management operation unit 163 to operate the Line selection region B2. For example, when the predetermined mounting apparatus 12 is selected by an input operation into the Line selection region B2, the management control unit 165 causes the management display unit 162 to display the suction position offset distribution AD indicating distribution of the data group including each suction position offset data D1 output from the mounting communication unit 40 of the predetermined mounting apparatus 12.
The component selection region B3, the head selection region B4, the nozzle selection region B5, and the feeder selection region B6 that are set on the display screen DS1 are regions to input a command to select one piece of parameter information from the component information D21, the head information D22, the nozzle information D23, and the feeder information D24 that constitute the parameter information D2 associated with the suction position offset data D1. The operator can input a command to select the component information D21 from the parameter information D2 by using the management operation unit 163 to operate the component selection region B3. Similarly, the operator can input a command to select the head information D22 from the parameter information D2 by using the management operation unit 163 to operate the head selection region B4. The operator can input a command to select the nozzle information D23 from the parameter information D2 by using the management operation unit 163 to operate the nozzle selection region B5. The operator can input a command to select the feeder information D24 from the parameter information D2 by using the management operation unit 163 to operate the feeder selection region B6.
The management control unit 165 causes the management display unit 162 to display the suction position offset distribution AD focusing on one piece of information selected from the parameter information D2 to be switchable as the parameter selection changes. Specifically, the management control unit 165 controls the management display unit 162 such that, when a command to select the component information D21 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD focusing on the component identified by the component information D21 is displayed. Similarly, the management control unit 165 controls the management display unit 162 such that, when a command to select the head information D22 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD focusing on the loading head 251 identified by the head information D22 is displayed. The management control unit 165 controls the management display unit 162 such that, when a command to select the nozzle information D23 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD focusing on the suction nozzle 2511 identified by the nozzle information D23 is displayed. The management control unit 165 controls the management display unit 162 such that, when a command to select the feeder information D24 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD focusing on the feeder 24F identified by the feeder information D24 is displayed.
Here, the component, the loading head 251, the suction nozzle 2511, and the feeder 24F that are respectively identified by the component information D21, the head information D22, the nozzle information D23, and the feeder information D24 that constitute the parameter information D2 associated with the suction position offset data D1 of the suction position offset distribution AD can be a generating factor for the component suction position offset by the suction nozzle 2511. That is, the posture and shape of the component supplied by the feeder 24F affect the suction and holding performance of the component by the suction nozzle 2511. The operating characteristics and the status of aged deterioration of the suction nozzle 2511 and the loading head 251 also affect the suction and holding performance of the component by the suction nozzle 2511.
Therefore, the management display unit 162 displays the suction position offset distribution AD focusing on one piece of information selected from the parameter information D2 via the management operation unit 163 based on the control of the management display unit 162 by the management control unit 165. This allows the operator to identify the generating factor for the suction position offset while visually checking the generating status of component suction position offset by the suction nozzle 2511.
Assume a case where the suction position offset data D1 exists that exceeds a suction offset allowable range AAT indicating the allowable range of the offset amount of the suction position of the component with respect to the suction nozzle 2511 in the suction position offset distribution AD. In this case, the management control unit 165 may control the management display unit 162 such that the suction position offset data D1 exceeding the suction offset allowable range AAT is displayed in a different display mode from the display mode of other position offset data. For example, the management control unit 165 controls the management display unit 162 such that the display color of the plot of the suction position offset data D1 exceeding the suction offset allowable range AAT is different from the display color of other position offset data.
As shown in
Each image that constitutes the processing state image G2 is an image associated with the suction position offset data D1, and is an image indicating the processing state of each process of the component supply process of the feeder 24F, the component suction process of the suction nozzle 2511, and the component loading process of the loading head 251. The operator can accurately determine the influence of the processes of the component supply process, the component suction process, and the component loading process on the suction position offset by checking each image that constitutes the processing state image G2 displayed simultaneously with the suction position offset distribution AD in the management display unit 162 in response to the selection command of the specific position offset data D1S via the management operation unit 163. This allows the operator to more accurately identify the generating factor for the suction position offset. After identifying the generating factor for the suction position offset, the operator can take appropriate measures against the generating factor, and can thereby solve the defect of the position offset of the component loading position on the pattern forming board PP caused by the suction position offset.
When the component is identified as the generating factor for the suction position offset, for example, the operator checks input values of parameters such as external dimensions of the component registered in the component information D21 of the board data D25. When the parameter of the component information D21 is input incorrectly or the like, as a countermeasure for the generating factor for the suction position offset, the operator executes data change work to change the data of the component information D21.
When the loading head 251 is identified as the generating factor for the suction position offset, for example, the operator confirms whether the suckable position set as a descending position of the loading head 251 is appropriate when the suction nozzle 2511 sucks the component. Then, when the suckable position set for the loading head 251 is not appropriate, the operator executes work to adjust the suckable position set for the loading head 251 as a countermeasure for the generating factor for the suction position offset. When the loading head 251 is found to have aged deterioration, the operator executes work to replace the loading head 251 or the like.
When the suction nozzle 2511 is identified as the generating factor for the suction position offset, for example, the operator executes work to clean or replace the suction nozzle 2511 or the like as a countermeasure for the generating factor for the suction position offset.
When the feeder 24F is identified as the generating factor for the suction position offset, for example, the operator executes work to replace the feeder 24F or the like as a countermeasure for the generating factor for the suction position offset.
In the present embodiment, when a command to select the specific position offset data D1S is input via the management operation unit 163, the management control unit 165 controls the management display unit 162 such that the image group GG including the loading board image G3 in addition to various images that constitute the processing state image G2 is displayed simultaneously with the suction position offset distribution AD. By checking the processing state image G2 and the loading board image G3 displayed simultaneously with the suction position offset distribution AD in the management display unit 162, the operator can confirm whether the position offset of the component suction position by the suction nozzle 2511 affects the position offset of the component loading position on the pattern forming board PP. By comparing each image that constitutes the processing state image G2 with the loading board image G3, the operator can also confirm whether the component position offset has occurred while the component loading board PPA is conveyed from the mounting apparatus 12 to the loading inspection device 13.
Furthermore, in the present embodiment, when a command to select the specific position offset data D1S is input via the management operation unit 163, the management control unit 165 controls the management display unit 162 such that the image group GG including the pattern board image G1 and the reflow board image G4 in addition to the processing state image G2 and the loading board image G3 is displayed simultaneously with the suction position offset distribution AD. By checking the pattern board image G1 displayed simultaneously with the suction position offset distribution AD in the management display unit 162, the operator can confirm the influence of the formation status of the solder paste pattern on the suction position offset. By checking the reflow board image G4 displayed simultaneously with the suction position offset distribution AD in the management display unit 162, the operator can confirm the position offset status of the component on the reflow board PPB after the reflow process.
When a loading offset display command to display the position offset status of the component loading position on the component loading board PPA is input via the management operation unit 163, the management control unit 165 causes the management display unit 162 to display a display screen DS2 as shown in
Based on the loading position offset distribution PD displayed in the management display unit 162, the operator can visually check the generating status of the position offset of the actual component loading position on the component loading board PPA produced by the mounting apparatus 1. By comparing the suction position offset distribution AD with the loading position offset distribution PD shown in the management display unit 162, the operator can confirm whether the position offset of the actual component suction position by the suction nozzle 2511 affects the position offset of the actual component loading position on the component loading board PPA.
At this time, the management control unit 165 may control the management display unit 162 such that loading position offset statistical information PST indicating the statistics of the data group including each loading position offset data D5 is displayed simultaneously with the loading position offset distribution PD.
The management control unit 165 controls the management display unit 162 such that the date selection region B1, the Line selection region B2, the component selection region B3, the head selection region B4, the nozzle selection region B5, and the feeder selection region B6 that allow an input operation via the management operation unit 163 are set on the display screen DS2. By using the management operation unit 163 to operate the date selection region B1, the operator can select the acquisition date or acquisition period by the data calculation unit 1333 of the inspection control unit 133 for each loading position offset data D5 that constitutes the loading position offset distribution PD. By using the management operation unit 163 to operate the Line selection region B2, the operator can select the mounting apparatus 12 corresponding to each loading position offset data D5 that constitutes the loading position offset distribution PD, and the like. The component selection region B3, the head selection region B4, the nozzle selection region B5, and the feeder selection region B6 that are set on the display screen DS2 are regions to input a command to select one piece of parameter information from the component information D21, the head information D22, the nozzle information D23, and the feeder information D24 that constitute the parameter information D2 associated with the loading position offset data D5, in a similar manner to the display screen DS1 described above.
The management control unit 165 causes the management display unit 162 to display the loading position offset distribution PD focusing on one piece of information selected from the parameter information D2 to be switchable as the parameter selection changes. Specifically, the management control unit 165 controls the management display unit 162 such that, when a command to select the component information D21 from the parameter information D2 is input via the management operation unit 163, the loading position offset distribution PD focusing on the component identified by the component information D21 is displayed. Similarly, the management control unit 165 controls the management display unit 162 such that, when a command to select the head information D22 from the parameter information D2 is input via the management operation unit 163, the loading position offset distribution PD focusing on the loading head 251 identified by the head information D22 is displayed. The management control unit 165 controls the management display unit 162 such that, when a command to select the nozzle information D23 from the parameter information D2 is input via the management operation unit 163, the loading position offset distribution PD focusing on the suction nozzle 2511 identified by the nozzle information D23 is displayed. The management control unit 165 controls the management display unit 162 such that, when a command to select the feeder information D24 from the parameter information D2 is input via the management operation unit 163, the loading position offset distribution PD focusing on the feeder 24F identified by the feeder information D24 is displayed.
In this way, the management display unit 162 displays the loading position offset distribution PD focusing on one piece of information selected via the management operation unit 163 from the parameter information D2 based on the control of the management display unit 162 by the management control unit 165. This allows the operator to identify the generating factor for the loading position offset while visually checking the generating status of component loading position offset on the component loading board PPA.
Assume a case where the loading position offset data D5 exists that exceeds a loading offset allowable range PAT indicating the allowable range of the offset amount of the loading position of the component on the component loading board PPA in the loading position offset distribution PD. In this case, the management control unit 165 may control the management display unit 162 such that the loading position offset data D5 exceeding the loading offset allowable range PAT is displayed in a different display mode from the display mode of other position offset data. For example, the management control unit 165 controls the management display unit 162 such that the display color of the plot of the loading position offset data D5 exceeding the loading offset allowable range PAT is different from the display color of other position offset data.
As shown in
By checking each image that constitutes the processing state image G2 and the loading board image G3 displayed in the management display unit 162 simultaneously with the loading position offset distribution PD in response to a selection command of the specific position offset data D5S via the management operation unit 163, the operator can confirm whether the position offset of the component suction position by the suction nozzle 2511 affects the position offset of the component loading position on the component loading board PPA.
In the present embodiment, when the command to select the specific position offset data D5S is input via the management operation unit 163, the management control unit 165 controls the management display unit 162 such that the image group GG including the pattern board image G1 and the reflow board image G4 in addition to the processing state image G2 and the loading board image G3 is displayed simultaneously with the loading position offset distribution PD.

At this time, the management control unit 165 may control the management display unit 162 such that the suction position offset statistical information AST and the loading position offset statistical information PST are displayed simultaneously with the suction position offset distribution AD and the loading position offset distribution PD.
The management control unit 165 controls the management display unit 162 such that the date selection region B1, the Line selection region B2, the component selection region B3, the head selection region B4, the nozzle selection region B5, and the feeder selection region B6 that allow an input operation via the management operation unit 163 are set on the display screen DS3. The operator can select the acquisition date or acquisition period of each suction position offset data D1 that constitutes the suction position offset distribution AD and each loading position offset data D5 that constitutes the loading position offset distribution PD by using the management operation unit 163 to operate the date selection region B1.

The component selection region B3, the head selection region B4, the nozzle selection region B5, and the feeder selection region B6 that are set on the display screen DS3 are regions to input a command to select one piece of parameter information from the component information D21, the head information D22, the nozzle information D23, and the feeder information D24 that constitute the parameter information D2 associated with the suction position offset data D1 and the loading position offset data D5, in a similar manner to the display screens DS1 and DS2 described above.
The management control unit 165 causes the management display unit 162 to simultaneously display the suction position offset distribution AD and the loading position offset distribution PD focusing on one piece of information selected from the parameter information D2 to be switchable as the parameter selection changes. Specifically, the management control unit 165 controls the management display unit 162 such that, when a command to select the component information D21 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD and the loading position offset distribution PD focusing on the component identified by the component information D21 are simultaneously displayed. Similarly, the management control unit 165 controls the management display unit 162 such that, when a command to select the head information D22 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD and the loading position offset distribution PD focusing on the loading head 251 identified by the head information D22 are simultaneously displayed. Specifically, the management control unit 165 controls the management display unit 162 such that, when a command to select the nozzle information D23 from the parameter information D2 is input via the management operation unit 163, the suction position offset distribution AD and the loading position offset distribution PD focusing on the suction nozzle 2511 identified by the nozzle information D23 are simultaneously displayed.

This allows the operator to easily compare the suction position offset distribution AD with the loading position offset distribution PD.
As shown in
By checking each image that constitutes the processing state image G2 displayed in the management display unit 162 in response to a selection command of the specific position offset data DIS via the management operation unit 163 and the loading board image G3, the operator can confirm whether the position offset of the component suction position by the suction nozzle 2511 affects the position offset of the component loading position on the component loading board PPA. In the present embodiment, when a command to select the specific position offset data D1S is input via the management operation unit 163, the management control unit 165 controls the management display unit 162 such that the image group GG including the pattern board image G1 and the reflow board image G4 in addition to the processing state image G2 and the loading board image G3 is displayed simultaneously with the suction position offset distribution AD and the loading position offset distribution PD.

By checking the reflow board image G4 displayed in the management display unit 162, the operator can confirm the position offset status of the component on the reflow board PPB after the reflow process.
Furthermore, assume a case where a command to select one or more specific position offset data from the data group of one position offset distribution is input via the management operation unit 163, with the suction position offset distribution AD and the loading position offset distribution PD simultaneously displayed in the management display unit 162. As described above,
Accordingly, in the suction position offset distribution AD and the loading position offset distribution PD simultaneously displayed in the management display unit 162, the correspondence between the specific position offset data D1S and the attention data D5A becomes clear. Therefore, the operator can accurately confirm the correspondence between the specific position offset data D1S selected via the management operation unit 163 and the attention data D5A. As a result, the operator can more easily confirm whether the position offset of the component suction position by the suction nozzle 2511 affects the position offset of the component loading position on the component loading board PPA.
The management control unit 165 may be configured to cause the management display unit 162 to display a display screen DS4 illustrated in
This allows the management control unit 165 to cause the management display unit 162 to display the temporal transition of the suction position offset data D1 and the loading position offset data D5 as graphic visualization simultaneously with the suction position offset distribution AD and the loading position offset distribution PD. Therefore, the operator can check the temporal transition of the position offset based on the suction position offset transition graph AG and the loading position offset transition graph PG while visually checking the generating status of the position offset based on the suction position offset distribution AD and the loading position offset distribution PD.
Note that the management control unit 165 may be configured to control the management display unit 162 such that at least one position offset distribution of the suction position offset distribution AD and the loading position offset distribution PD, and at least one transition graph of the suction position offset transition graph AG and the loading position offset transition graph PG are displayed simultaneously. In this case, the management control unit 165 treats the suction position offset distribution AD and the suction position offset transition graph AG as one set, and treats the loading position offset distribution PD and the loading position offset transition graph PG as one set. That is, the management control unit 165 controls the management display unit 162 such that the suction position offset distribution AD and the suction position offset transition graph AG are displayed simultaneously, and the loading position offset distribution PD and the loading position offset transition graph PG are displayed simultaneously.
Assume a case where a command to select one or more specific position offset data is input via the management operation unit 163 from the data group of one position offset distribution of the suction position offset distribution AD and the loading position offset distribution PD, with the suction position offset distribution AD, the loading position offset distribution PD, the suction position offset transition graph AG, and the loading position offset transition graph PG simultaneously displayed in the management display unit 162.
Specifically, in the data group of the loading position offset data D5 that constitutes the loading position offset distribution PD, the attention data D5A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. Similarly, in the data group of the suction position offset data D1 that constitutes the suction position offset transition graph AG, attention data D1A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. In the data group of the loading position offset data D5 that constitutes the loading position offset transition graph PG, the attention data D5A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. For example, the management control unit 165 controls the management display unit 162 such that the brightness and contrast of the plot of the attention data D5A in the loading position offset distribution PD, the attention data D1A in the suction position offset transition graph AG, and the attention data D5A in the loading position offset transition graph PG are different from the residual data.
Therefore, the correspondence of respective position offset data becomes clear in the suction position offset distribution AD, the loading position offset distribution PD, the suction position offset transition graph AG, and the loading position offset transition graph PG that are simultaneously displayed in the management display unit 162. This allows the operator to accurately confirm the correspondence between the suction position offset data D1 and the loading position offset data D5, including the temporal transition. As a result, the operator can easily confirm whether the position offset of the component suction position by the suction nozzle 2511 affects the position offset of the component loading position on the component loading board PPA, including the temporal factor.
Assume a case where a command to select one or more specific position offset data from the data group of the position offset distribution displayed in the management display unit 162 is input via the management operation unit 163, with at least one position offset distribution of the suction position offset distribution AD and the loading position offset distribution PD, and at least one transition graph of the suction position offset transition graph AG and the loading position offset transition graph PG simultaneously displayed in the management display unit 162. In this case, in each data group of position offset distribution when the position offset distribution other than the position offset distribution subjected to the command by the management operation unit 163 is displayed in the management display unit 162, and the transition graph displayed in the management display unit 162, the management control unit 165 controls the management display unit 162 such that the attention data corresponding to the specific position offset data is displayed in a different display mode from the display mode of the residual data.
As in a display screen DS5 illustrated in
Specifically, in the data group of the loading position offset data D5 that constitutes the loading position offset transition graph PG, the attention data D5A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. Similarly, in the data group of the suction position offset data D1 that constitutes the suction position offset distribution AD, the attention data D1A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. In the data group of the loading position offset data D5 that constitutes the loading position offset distribution PD, the attention data D5A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. For example, the management control unit 165 controls the management display unit 162 such that the brightness and contrast of the plot of the attention data D5A in the loading position offset transition graph PG, the attention data D1A in the suction position offset distribution AD, and the attention data D5A in the loading position offset distribution PD are different from the residual data.
Therefore, the correspondence of respective position offset data becomes clear in the suction position offset distribution AD, the loading position offset distribution PD, the suction position offset transition graph AG, and the loading position offset transition graph PG that are simultaneously displayed in the management display unit 162. This allows the operator to accurately confirm the correspondence between the suction position offset data D1 and the loading position offset data D5, including the temporal transition.
Assume a case where a command to select one or more specific position offset data from the data group of the transition graph displayed in the management display unit 162 is input via the management operation unit 163, with at least one position offset distribution of the suction position offset distribution AD and the loading position offset distribution PD, and at least one transition graph of the suction position offset transition graph AG and the loading position offset transition graph PG are simultaneously displayed in the management display unit 162. In this case, the management control unit 165 controls the management display unit 162 such that, in each data group of the transition graph when the transition graph other than the transition graph subjected to the command by the management operation unit 163 is displayed in the management display unit 162, and the position offset distribution displayed in the management display unit 162, the attention data corresponding to the specific position offset data is displayed in a different display mode from the display mode of the residual data.
The management control unit 165 may be configured to cause the management display unit 162 to display a display screen DS6 illustrated in
This allows the management control unit 165 to cause the management display unit 162 to display the temporal transition of the suction level data D3 indicating the component suction level by the suction nozzle 2511 as graphic visualization simultaneously with the suction position offset distribution AD and the loading position offset distribution PD. Therefore, the operator can check the temporal transition of the suction level data D3 based on the suction level transition graph ALG while visually checking the generating status of the position offset based on the suction position offset distribution AD and the loading position offset distribution PD.
At this time, assume a case where a command to select one or more specific position offset data from the data group of one position offset distribution of the suction position offset distribution AD and the loading position offset distribution PD is input via the management operation unit 163, with the suction position offset distribution AD, the loading position offset distribution PD, and the suction level transition graph ALG simultaneously displayed in the management display unit 162.
Specifically, in the data group of the loading position offset data D5 that constitutes the loading position offset distribution PD, the attention data D5A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. Similarly, in the data group of the suction level data D3 that constitutes the suction level transition graph ALG, attention data D3A corresponding to the specific position offset data D1S is displayed in a different display mode from the display mode of the residual data. For example, the management control unit 165 controls the management display unit 162 such that the brightness and contrast of the plot of the attention data D5A in the loading position offset distribution PD and the attention data D3A in the suction level transition graph ALG are different from the residual data.
Accordingly, in the suction position offset distribution AD, the loading position offset distribution PD, and the suction level transition graph ALG that are displayed simultaneously in the management display unit 162, the correspondence between the position offset data D1, D5 and the suction level data D3 becomes clear. Therefore, the operator can accurately confirm the correspondence between the position offset data D1, D5 and the suction level data D3. As a result, the operator can confirm whether the position offset of the component suction position by the suction nozzle 2511 affects the position offset of the component loading position on the component loading board PPA by focusing on the component suction level by the suction nozzle 2511.
Assume a case where a command to select one or more specific position offset data from the data group of the position offset distribution displayed in the management display unit 162 is input via the management operation unit 163, with at least one position offset distribution of the suction position offset distribution AD and the loading position offset distribution PD, and the suction level transition graph ALG simultaneously displayed in the management display unit 162. In this case, the management control unit 165 controls the management display unit 162 such that the attention data corresponding to the specific position offset data is displayed in a different display mode from the display mode of the residual data, in each data group of position offset distribution when the position offset distribution other than the position offset distribution subjected to the command by the management operation unit 163 is displayed in the management display unit 162, and the suction level transition graph ALG.
The management control unit 165 may be configured to calculate a normal suction rate based on the suction state data D4 included in each management data DM accumulated and stored in the management storage unit 164. Specifically, the management control unit 165 calculates the normal suction rate about the component, the loading head 251, the suction nozzle 2511, and the feeder 24F respectively indicated by the component information D21, the head information D22, the nozzle information D23, and the feeder information D24 that constitute the parameter information D2. The normal suction rate indicates the proportion of the number of times of use in the situation where the suction state indicated by the suction state data D4 is normal to the total number of times of use in a predetermined designated period about each of the component, the loading head 251, the suction nozzle 2511, and the feeder 24F. That is, when considering each type of the component, each type of the loading head 251, each type of the suction nozzle 2511, and each type of the feeder 24F, as the normal suction rate increases, the number of times of use increases in a situation where the suction state of the component by the suction nozzle 2511 is normal. Therefore, as the normal suction rate increases, it is more difficult to think the generating factor for the suction position offset and the loading position offset.
As in a display screen DS7 illustrated in
The operator can check the normal suction rate in each of the component, the loading head 251, the suction nozzle 2511, and the feeder 24F based on the normal suction rate table ART displayed in the management display unit 162. This allows the operator to easily identify the generating factor for the suction position offset and the loading position offset.
Note that the above-described specific embodiment mainly includes the disclosure having the following configurations.
A component mounting system according to one aspect of the present disclosure includes a mounting apparatus including a feeder configured to execute a component supply process of supplying a component and a loading head including a suction nozzle that executes a component suction process of sucking the component to obtain a component loading board by executing a component loading process of loading the component sucked by the suction nozzle on a board: and a management device connected to the mounting apparatus to allow data communication. The management device includes a management communication unit configured to acquire, from the mounting apparatus, suction position offset data indicating an offset amount of a suction position of the component with respect to the suction nozzle in the component suction process, various pieces of parameter information to identify each of the component, the feeder, the suction nozzle, and the loading head used in each process of the component supply process, the component suction process, and the component loading process, and various processing state images each indicating an image of a processing state of each of the processes. The management device further includes a management storage unit configured to accumulate and store management data in which the suction position offset data, the various pieces of parameter information, and the various processing state images are associated with each other: a management display unit configured to display information on the management data: a management operation unit into which a command regarding a display mode of the management display unit is input: and a management control unit configured to control the management display unit in response to the command input into the management operation unit. The management control unit controls the management display unit such that, when a command to select one piece of parameter information from the various pieces of parameter information is input via the management operation unit, suction position offset distribution indicating distribution of a data group of the suction position offset data focusing on the one piece of parameter information is displayed. The management control unit controls the management display unit such that, when a command to select one or a plurality of the specific suction position offset data from the data group of the suction position offset distribution is input via the management operation unit with the suction position offset distribution displayed in the management display unit, the various processing state images corresponding to the specific suction position offset data are displayed simultaneously with the suction position offset distribution.
With the component mounting system, the mounting apparatus and the management device are connected to allow data communication. In the management device, the management storage unit accumulates and stores the management data in which the suction position offset data, the various pieces of parameter information, and the various processing state images acquired from the mounting apparatus by the management communication unit are associated with each other. When a command to select one piece of parameter information from the various pieces of parameter information is input via the management operation unit, the management control unit causes the management display unit to display the suction position offset distribution indicating the distribution of the data group of the suction position offset data focusing on the one piece of parameter information.
The component, the feeder, the suction nozzle, and the loading head identified by the various pieces of parameter information associated with the suction position offset data can be a generating factor for the suction position offset of the component by the suction nozzle. That is, the posture and shape of the component supplied by the feeder affect the suction and holding performance of the component by the suction nozzle. The operating characteristics and the status of aged deterioration of the suction nozzle and the loading head also affect the suction and holding performance of the component by the suction nozzle. Since the suction position offset distribution focusing on the parameter information selected via the management operation unit is displayed in the management display unit, the operator can identify the generating factor for the suction position offset while visually checking the generating status of the suction position offset of the component by the suction nozzle.
When a command to select one or more specific position offset data from the data group of the suction position offset distribution is input via the management operation unit with the suction position offset distribution displayed in the management display unit, the management control unit causes the management display unit to display the various processing state images corresponding to the specific position offset data simultaneously with the suction position offset distribution. The various processing state images are images associated with the suction position offset data, and are images indicating the processing state of various processes of the component supply process of the feeder, the component suction process of the suction nozzle, and the component loading process of the loading head. The operator can accurately determine the influence of the processes of the component supply process, the component suction process, and the component loading process on the suction position offset by checking the processing state images displayed simultaneously with the suction position offset distribution in the management display unit in response to the selection command of the specific position offset data via the management operation unit. This allows the operator to more accurately identify the generating factor for the suction position offset. After identifying the generating factor for the suction position offset, the operator can take appropriate measures against the generating factor, and can thereby solve the defect of the position offset of the component loading position on the board caused by the suction position offset.
The component mounting system may further include a loading inspection device connected to the management device to allow data communication and configured to inspect the component loading board based on a loading board image indicating an image of the component loading board. The management communication unit is configured to acquire, from the loading inspection device, loading position offset data indicating an offset amount of a loading position of the component with respect to the board in the component loading process, and the loading board image, and the management storage unit is configured to accumulate and store data in which the loading position offset data is further associated with the loading board image as the management data. The management control unit controls the management display unit such that, when the command to select the one piece of parameter information from the various pieces of parameter information is input via the management operation unit, at least one position offset distribution of loading position offset distribution indicating distribution of a data group of the loading position offset data focusing on the one piece of parameter information and the suction position offset distribution is displayed. The management control unit controls the management display unit such that, when a command to select one or more specific position offset data from the data group of the position offset distribution is input via the management operation unit, with the at least one position offset distribution of the suction position offset distribution and the loading position offset distribution displayed in the management display unit, the various processing state images and the loading board image corresponding to the specific position offset data are displayed simultaneously with the position offset distribution.
In this aspect, the management control unit can cause the management display unit to display the loading position offset distribution indicating the distribution of the data group of the loading position offset data acquired from the loading inspection device by the management communication unit. Based on the loading position offset distribution displayed in the management display unit, the operator can visually confirm the generating status of the position offset of the component loading position on the component loading board produced by the mounting apparatus.
When the command to select the specific position offset data is input via the management operation unit, with at least one position offset distribution of the suction position offset distribution and the loading position offset distribution displayed in the management display unit, the management control unit causes the management display unit to display the loading board image simultaneously with the position offset distribution in addition to the various processing state images. By checking the various processing state images and the loading board image displayed simultaneously with the position offset distribution in the management display unit, the operator can confirm whether the position offset of the component suction position by the suction nozzle affects the position offset of the component loading position on the board.
The component mounting system may further include: a pattern inspection device connected to the management device to allow data communication and configured to inspect a pattern forming board based on a pattern board image indicating an image of the pattern forming board on which a solder paste pattern used in the component loading process is formed: and a reflow inspection device connected to the management device to allow data communication and configured to inspect a reflow board based on a reflow board image indicating an image of the reflow board after a reflow process is applied to the component loading board. The management communication unit is configured to acquire the pattern board image from the pattern inspection device and to acquire the reflow board image from the reflow inspection device, and the management storage unit is configured to accumulate and store data in which the pattern board image is further associated with the reflow board image as the management data. The management control unit controls the management display unit such that, when the command to select the one or more specific position offset data from the data group of the position offset distribution is input via the management operation unit, with the at least one position offset distribution of the suction position offset distribution and the loading position offset distribution displayed in the management display unit, the various processing state images, the loading board image, the pattern board image, and the reflow board image corresponding to the specific position offset data are displayed simultaneously with the position offset distribution.
In this aspect, when the command to select the specific position offset data is input via the management operation unit, with at least one position offset distribution of the suction position offset distribution and the loading position offset distribution displayed in the management display unit, the management control unit causes the management display unit to display the pattern board image and the reflow board image simultaneously with the position offset distribution in addition to the various processing state images and the loading board image. By checking the pattern board image displayed in the management display unit simultaneously with the position offset distribution, the operator can confirm the influence of the formation status of the solder paste pattern on the suction position offset and the loading position offset. By checking the reflow board image displayed simultaneously with the position offset distribution in the management display unit, the operator can confirm the position offset status of the component on the reflow board after the reflow process.
In the component mounting system, the management control unit may be configured to control the management display unit such that, when the command to select the one piece of parameter information from the various pieces of parameter information is input via the management operation unit, the suction position offset distribution and the loading position offset distribution focusing on the one piece of parameter information are displayed simultaneously. In this case, the management control unit controls the management display unit such that, when the command to select the one or more specific position offset data from the data group of the one position offset distribution is input via the management operation unit, with the suction position offset distribution and the loading position offset distribution displayed simultaneously in the management display unit, attention data corresponding to the specific position offset data is displayed in a different display mode from a display mode of residual data in the data group of another position offset distribution.
In this aspect, when the command to select one piece of parameter information from the various pieces of parameter information is input via the management operation unit, the management control unit causes the management display unit to simultaneously display the suction position offset distribution and the loading position offset distribution focusing on the one piece of parameter information. This allows the operator to easily compare the suction position offset distribution with the loading position offset distribution. Therefore, the operator can easily confirm whether the position offset of the component suction position by the suction nozzle affects the position offset of the component loading position on the board.
Assume a case where the command to select the one or more specific position offset data from the data group of one position offset distribution is input via the management operation unit, with the suction position offset distribution and the loading position offset distribution simultaneously displayed in the management display unit. In this case, the management control unit controls the management display unit such that, in the data group of the other position offset distribution, the attention data corresponding to the specific position offset data is displayed in a different display mode from the display mode of the residual data. Accordingly, in the suction position offset distribution and the loading position offset distribution simultaneously displayed in the management display unit, the correspondence between the suction position offset data and the loading position offset data becomes clear. Therefore, the operator can accurately confirm the correspondence between the suction position offset data and the loading position offset data. As a result, the operator can more easily confirm whether the position offset of the component suction position by the suction nozzle affects the position offset of the component loading position on the board.
In the component mounting system, the management control unit may be configured to control the management display unit such that, when the command to select the one piece of parameter information from the various pieces of parameter information is input via the management operation unit, at least one transition graph of a suction position offset transition graph indicating temporal transition of the data group of the suction position offset data and a loading position offset transition graph indicating temporal transition of the data group of the loading position offset data is displayed simultaneously with at least one position offset distribution of the suction position offset distribution and the loading position offset distribution.

Accordingly, simultaneously with at least one position offset distribution of the suction position offset distribution and the loading position offset distribution, temporal transition of at least one position offset data of the suction position offset data and the loading position offset data can be displayed in the management display unit as graphic visualization. Therefore, the operator can confirm the temporal transition of the position offset based on at least one transition graph of the suction position offset transition graph and the loading position offset transition graph while visually checking the generating status of the position offset based on at least one position offset distribution of the suction position offset distribution and the loading position offset distribution.

Therefore, the correspondence of respective position offset data becomes clear in the suction position offset distribution, the loading position offset distribution, the suction position offset transition graph, and the loading position offset transition graph that are simultaneously displayed in the management display unit. Therefore, the operator can accurately confirm the correspondence between the suction position offset data and the loading position offset data, including the temporal transition. As a result, the operator can easily confirm whether the position offset of the component suction position by the suction nozzle affects the position offset of the component loading position on the board, including the temporal factor.

Therefore, the correspondence of respective position offset data becomes clear in the suction position offset distribution, the loading position offset distribution, the suction position offset transition graph, and the loading position offset transition graph that are simultaneously displayed in the management display unit. Therefore, the operator can accurately confirm the correspondence between the suction position offset data and the loading position offset data, including the temporal transition.
