Mounting head 26 mounts an electronic component on the circuit board. Mounting head 26 includes suction nozzle 60 provided on a lower end surface. Suction nozzle 60 communicates with positive and negative pressure supply device (see
Supply device 28 is disposed at an end portion on a front side of frame 32, and includes multiple tape feeders 70. As illustrated in
In addition, peeling device 76 includes film peeling mechanism 86 and gear mechanism 88. Film peeling mechanism 86 is a mechanism for peeling top film 90 from taped component 78, and is disposed in front of opening 92 formed in an upper surface end portion of tape feeder 70. Gear mechanism 88 is a mechanism for pulling top film 90 peeled from taped component 78 into film collection section 94. With such a configuration, top film 90 is peeled from taped component 78, so that the electronic component accommodated in taped component 78 is exposed in opening 92, and the exposed electronic component is picked up and held by suction nozzle 60 of mounting head 26. That is, opening 92 is the supply position of the electronic component of tape feeder 70. Tape guide passage 96 is formed on a side surface of opening 92 in a feed-out direction of taped component 78 to be directed downward. Waste tape 98 from which the electronic component is extracted from taped component 78 is discharged through tape guide passage 96.

Tape feeder 70 includes memory (see
As illustrated in
In electric component mounting device 10, with the configuration described above, mounting head 26 executes the mounting work on the circuit board held by conveyance device 22. Specifically, the circuit board is conveyed to a work position by a command from controller 130, and the circuit board is fixedly held by board holding device 48 at the work position. Tape feeder 70 feeds out the taped component to supply the electronic component at the supply position based on the command from controller 130. Then, mounting head 26 is moved to an upper side of the supply position of the electronic component by the command from controller 130, and picks up and holds the electronic component by suction nozzle 60. Then, mounting head 26 moves above the circuit board to mount the electronic component on the circuit board.
In this way, in electric component mounting device 10, the electronic component supplied from tape feeder 70 is mounted on the circuit board. In controller 130 that controls the operation of electric component mounting device 10, the number of times of supply of the electronic component supplied from each of multiple tape feeders 70 is counted for each tape feeder, and the number of times of supply of the electronic component by tape feeder 70 and the identification information of tape feeder 70 are stored in association with each other. Also in each of multiple tape feeders 70, the number of times of supply of the electronic component is counted, and the counted number of times of supply is stored in memory 120.
In electric component mounting device 10, basically, the tape feeder used in the mounting work is mounted on tape feeder mounting stand 110, and the tape feeder not used in the mounting work is housed in housing system 150 illustrated in
As illustrated in
As illustrated in
Further, controller 170 is connected to LED lamp 168 and connector connection portion 162 of housing rack 152. As a result, controller 170 transmits a lighting command to LED lamp 168 of housing rack 152, thereby lighting LED lamp 168. When tape feeder 70 is housed in housing rack 152 and connector 100 of tape feeder 70 is connected to connector connection portion 162 of housing rack 152, controller 170 acquires the identification information and the like stored in memory 120 of tape feeder 70. In this case, controller 170 detects connector connection portion 162 to which connector 100 of tape feeder 70 is connected, thereby specifying a housing position of tape feeder 70 in housing rack 152, that is, slide groove 160 in which tape feeder 70 is housed. Then, controller 170 stores the acquired identification information of tape feeder 70 and the specified housing position of tape feeder 70 in memory 174 in association with each other. Management apparatus 154 for housing system 150 and control device 30 of electric component mounting device 10 are connected to each other, and various information is transmitted and received between management apparatus 154 and control device 30.
In housing system 150, with the configuration described above, tape feeder 70 necessary for the mounting work is guided during the setup work in electric component mounting device 10. Specifically, control device 30 of electric component mounting device 10 stores information (hereinafter, referred to as “necessary component information”) indicating the type of the electronic component necessary for the mounting work. Control device 30 also stores information (hereinafter, referred to as “association information”) in which the identification information of tape feeder 70 is associated with information (hereinafter, referred to as “accommodated component information”) indicating the type of the electronic component accommodated in tape feeder 70. Then, control device 30 transmits the necessary component information and the association information to management apparatus 154.
When controller 170 of management apparatus 154 receives the necessary component information and the association information, controller 170 extracts information matching the necessary component information from the accommodated component information included in the association information. Then, controller 170 specifies the identification information of tape feeder 70 associated with the extracted accommodated component information in the association information. Subsequently, controller 170 extracts the identification information matching the specified identification information from the identification information of tape feeder 70 stored in memory 174. Next, controller 170 specifies the housing position of tape feeder 70 associated with the extracted identification information in memory 174. Then, controller 170 transmits the lighting command to LED lamp 168 corresponding to the specified housing position of tape feeder 70, that is, slide groove 160 in which tape feeder 70 is housed, thereby lighting LED lamp 168 that has received the lighting command. Accordingly, tape feeder 70 accommodating the electronic components corresponding to the necessary component information is indicated by lighting of LED lamp 168, in housing rack 152. That is, tape feeder 70 which accommodates the electronic components necessary for the mounting work during the setup work in electric component mounting device 10 is indicated by the lighting of LED lamp 168, in housing rack 152. Accordingly, an operator can easily find, in housing rack 152, tape feeder 70 that is to be mounted on electric component mounting device 10 during the setup work in electric component mounting device 10. As described above, in housing system 150, the guide of tape feeder 70 necessary for the mounting work during the setup work in electric component mounting device 10 is performed by the lighting of LED lamp 168.
In housing system 150, it is possible to execute a mode (hereinafter, referred to as “maintenance mode”) of executing the guide of tape feeder 70 requiring the maintenance work, in addition to a mode (hereinafter, referred to as “main mode”) of executing the guide of tape feeder 70 necessary for the mounting work during the setup work. Specifically, maintenance information is also stored in memory 120 of tape feeder 70. The maintenance information includes the number of times of supply of the electronic component in tape feeder 70 and a previous maintenance execution date of tape feeder 70. In housing system 150, as described above, when tape feeder 70 is housed in housing rack 152, controller 170 acquires the identification information from memory 120 of tape feeder 70 and at the same time, controller 170 also acquires the maintenance information in addition to the identification information. Therefore, controller 170 stores the maintenance information in memory 174 of management apparatus 154 in association with the identification information of the tape feeder and the housing position of tape feeder 70.
As described above, in memory 174 of management apparatus 154, the identification information, the housing position, and the maintenance information of the tape feeder are stored in association with each other for each tape feeder housed in housing rack 152. In addition, memory 174 stores an upper limit value of the number of times of supply of the electronic component in tape feeder 70 (hereinafter, referred to as “upper limit number of times of supply”) and an upper limit value of an interval at which the maintenance of tape feeder 70 is executed (hereinafter, referred to as “upper limit period”). Then, controller 170 specifies the tape feeder (hereinafter, referred to as “maintenance target feeder”) requiring the maintenance based on the maintenance information, the upper limit number of times of supply, and the upper limit period stored in memory 174.
Specifically, controller 170 determines whether the number of times of supply of the electronic component included in the maintenance information exceeds the upper limit number of times of supply. When the number of times of supply of the electronic component exceeds the upper limit number of times of supply, controller 170 specifies the identification information of the tape feeder associated with the maintenance information including the number of times of supply of the electronic component. When the number of times of supply of the electronic component does not exceed the upper limit number of times of supply, controller 170 determines whether an elapsed period from the previous maintenance execution date included in the maintenance information exceeds the upper limit period. When the elapsed period from the previous maintenance execution date exceeds the upper limit period, controller 170 specifies the identification information of the tape feeder associated with the maintenance information including the previous maintenance execution date. In this manner, when controller 170 specifies the identification information of the tape feeder, controller 170 also specifies the housing position of the tape feeder associated with the specified identification information. Then, as illustrated in
In the maintenance mode, it is also possible to guide the tape feeder (hereinafter, referred to as “maintenance scheduled feeder”) requiring the maintenance not on the current day but on the next day or next week. Specifically, a period during which the operator wants to execute the maintenance is set. Then, controller 170 determines whether the number of times of supply of the tape feeder exceeds the upper limit number of times of supply within the set period. Specifically, for example, each time controller 170 acquires the maintenance information from the tape feeder, controller 170 cumulatively stores the acquired maintenance information and the date when the maintenance information is acquired, in association with each other. Then, controller 170 calculates the number of times of supply of the tape feeder per day, and estimates the number of times of supply (hereinafter referred to as “scheduled number of times of supply”) that is scheduled to reach the last day of the set period. Next, controller 170 determines whether the scheduled number of times of supply exceeds the upper limit number of times of supply. When the scheduled number of times of supply of the electronic component exceeds the upper limit number of times of supply, controller 170 specifies the identification information of the tape feeder associated with the maintenance information. When the scheduled number of times of supply of the electronic component does not exceed the upper limit number of times of supply, controller 170 determines whether a period to the last day of the set period from the previous maintenance execution date included in the maintenance information exceeds the upper limit period. When the period to the last day of the set period from the previous maintenance execution date exceeds the upper limit period, controller 170 specifies the identification information of the tape feeder associated with the maintenance information.
In this manner, when controller 170 specifies the identification information of the tape feeder, controller 170 also specifies the housing position of the tape feeder associated with the specified identification information. Then, controller 170 transmits the lighting command to the specified housing position, that is, LED lamp 168 corresponding to slide groove 160. As described above, in the maintenance mode, it is also possible to guide the maintenance scheduled feeder by lighting of LED lamp 168. Accordingly, it is possible to easily find, in housing rack 152, the tape feeder requiring the maintenance within the period desired by the operator, and to execute the maintenance of the tape feeder in accordance with the convenience of the operator.
Further, in the maintenance mode, in addition to guiding the maintenance target feeder and maintenance scheduled feeder by lighting of LED lamp 168, the guide is also performed by displaying the maintenance target feeder and the maintenance scheduled feeder on monitor 178. That is, when controller 170 specifies the identification information of the tape feeder, controller 170 displays the identification information of the tape feeder and the housing position of the tape feeder in housing rack 152 on monitor 178. Accordingly, the operator can recognize the presence or absence and the housing position of the maintenance target feeder and the maintenance scheduled feeder by checking monitor 178.

In such a case, at least one of LED lamp 168 of housing rack 152 and the LED lamp of the tape feeder need only be lighted.
In the example described above, controller 170 acquires the maintenance information from memory 120 of tape feeder 70, but may acquire the maintenance information from a device different from the tape feeder, such as control device 30 of electric component mounting device 10.
In the example described above, the number of times of supply of the electronic component by the tape feeder is adopted as the maintenance information, but various information can be adopted as long as the information indicates the number of operations of the tape feeder. Specifically, for example, the number of times the electronic component supplied from the tape feeder is held by a holder or the number of times sprocket 82 of tape feeder 70 rotates can be adopted.
