For example, when the motor 571 is a stepper motor, the motor 571 works after receiving a pulse voltage signal. For example, when the number of pulses of the pulse voltage signal is one, the output shaft of the motor 571 rotates a preset angle, thus the motor 571 can be controlled to rotate a desired angle by controlling a pulse number of the pulse voltage signal input into the motor 571, and accordingly the sliding block 552 and the baffle member 52 can be controlled to move a precise desired distance.

(degree Celsius) and the position where the baffle member 52 moves to cover an area of the air inlet opening 515 by the baffle member 52 is fully closed corresponding to the 31° C., thus the target position relationship information 619 in the display interface 61 is “fully closed position”.
For example, a number of target values of temperature 611 are displayed in the display interface 61, one target value of temperature 611 is 29° C., and the position where the baffle member 52 moves to cover an area of the air inlet opening 515 by the baffle member 52 is ⅗ of area of the air inlet opening 515 corresponding to the 29° C., thus the target position relationship information 619 in the display interface 61 is “⅗ closed position”.

It can be understood that the motor 571 can be a stepper motor. The current position of the sliding block 552 on the sliding rail 551 indicates a current position of the baffle member 52. One end of the sliding rail 551 can be a starting position of the sliding block 552, for example, in
For example, when the baffle member 52 covers ⅕ of area of the air inlet opening 515, the current temperature of the working space 11 is determined to be 27° C. according to the temperature detection information, namely, the current environmental temperature of the working station 12 is 27° C. The distance that the sliding block 552 is away from the starting position can be a distance N according to the current position of the sliding block 552 from the position detection unit 59. The control device 58 determines that the number of the pulses of the pulse voltage signal received by the motor 571 corresponding to the distance N is 8000. Thus, a content of “current pulse number 8000” is displayed in the current position column 613 of the display interface 61 when a content of “current temperature 27.00” is displayed in the current temperature column 612 of the display interface 61.
In some embodiments, a number of target position information of the sliding block 552 (hereinafter target position information 614) corresponding to the target value of temperature 611 are displayed in the display interface 61. A content of each target position information 614 can be a preset number of the pulses of the pulse voltage signal received by the motor 571 when the temperature of the working station 12 needs to reach a corresponding value of temperature and the sliding block 552 needs to move to a corresponding position from the starting position.
For example, if the baffle member 52 covers the air inlet opening 515 completely, namely, the air inlet opening 515 is fully closed, the sliding block 552 is at the starting position on the sliding rail 551, thus the displayed content of the target position information 614 is zero; if the baffle member 52 does not cover the air inlet opening 515 at all, namely, the air inlet opening 515 is fully open, the distance that the sliding block 552 is away from the starting position on the sliding rail 551 is a distance M, and the pulse number of the pulse voltage signal received by the motor 571 corresponding to the distance M is 11800, thus the displayed content of the target position information 614 is 11800.
For example, a number of target values of temperature 611 are displayed in the display interface 61, one target value of temperature 611 is 29° C., the displayed content of the target position information 614 on the display interface 61 corresponding to 29° C. is 4000. Where 4000 is the pulse number of the pulse voltage signal received by the motor 571 that needs to be reached, when the environmental temperature of the working station 12 needs to reach is 29° C., and the sliding block 552 needs to move to the target position relationship information corresponding to 29° C. from the starting position.
It can be understood that the control device 58 determines the target temperature information in response to an operation on the display interface 61 via the interactive system 60, for example, in response to a selection operation on one target value of temperature 611 of the display interface 61 via the interactive system 60. The control device 58 also obtains the target position information 614 corresponding to the target value of temperature 611. In some embodiments, the content of the target position information 614 can be a pulse number, and each target value of temperature 611 corresponds to one unique pulse number of the pulse voltage signal, thus each target temperature information corresponds to one unique pulse number. Similarity, each current temperature of the working space 11 corresponding to the temperature detection information corresponds to a current position of the sliding block 552 corresponding to the position detection information, and the content of the current position column 613 can be a pulse number, thus each temperature detection information corresponds to one unique pulse number. Thus, the control device 58 calculates a difference value of pulses between the number of the pulses corresponding to the target temperature information and the number of the pulses corresponding to the temperature detection information. In some embodiments, the difference value of the pulses can be the number of the pulses of the pulse voltage signal needing to output to the motor 571. In some embodiments, the control device 58 outputs a movement triggering signal whose number of the pulses is the difference value of pulses to the motor 571.
For example, the temperature of the environment where the working station 12 is located corresponding to the target temperature information is 29° C., and the current temperature of the working space 11 corresponding to the temperature detection information is 27° C., the content of the target position information 614 corresponding to the target temperature information is a pulse number of 4000, and the content of the current position column 613 in the display interface 61 is a pulse number of 8000, thus the control device 58 determines that that the difference value of pulses is 4000. The control device 58 outputs a movement triggering signal which is a pulse voltage signal with a number of the pulses of 4000 to the motor 571, to drive the sliding block 552 to move. The baffle member 52 is accordingly brought to cover a certain area of the air inlet opening 515 by the sliding block 552. Thus, the temperature of the environment where the working station 12 is located can be adjusted.
In some embodiments, the target values of temperature 611, the target position relationship information 619, and the target position information 614 are default configurations of the system 100. Thus, many preset values of temperature, much target position relationship information 619, and much target position information 614 can be displayed in the display interface 61. Each target value of temperature 611 corresponds to one target position relationship information 619 and one target position information 614.
In some embodiments, the control device 58 can add, edit, or delete one or more target values of temperature 611, one or more target position relationship information 619, and one or more target position information 614 in the display interface 61 in response to user operation on the display interface 61 via the interactive system 60. In some embodiments, one or more preset values of temperature 611, one or more target position relationship information 619, and one or more target position information 614 supporting customized settings can be displayed in the display interface 61, for example, preset temperature P:
It can be understood that the position detection unit 59 can detect a current position of the baffle member 52, the reference numeral 613 can be current position information of the baffle member 52, and the reference numeral 614 can be target position information of the baffle member 52, the disclosure is not limited herein.
In some embodiments, a data latching icon 615 and a data adjusting icon 616 can be displayed in the display interface 61. The operator can operate the interactive system 60 to select the data latching icon 615 or the data adjusting icon 616. When the data adjusting icon 616 is selected, the target values of temperature 611 and the target position information 614 can be adjusted, the operator can edit the target value of temperature 611 and the target position information 614. After the operator performs editing in the display interface 61, the operator can operate the interactive system 60 to select the data latching icon 615, then at that moment, the target value of the temperature 611 and the target position information 614 are not adjustable.
In some embodiments, the display interface 61 can include a data state column 617. When the data latching icon 615 is selected, the target value of temperature 611 and the target position information 614 cannot be adjusted, data is latched, a data state is a latched state, thus a content of the data state column 617 can be information corresponding to the latched state; when the data adjusting icon 616 is selected, the target value of temperature 611 and the target position information 614 can be adjusted, the data can be adjusted, the data state is an adjustable state, thus a content of the data state column 617 can be information corresponding to the adjustable state.
For example, the data state column 617 can be a text box whose shape is a rectangle and with some characters within. When the data state is the latched state, the content of the data state column 617 can be “the air inlet being automatically controlled”. When the data state is the adjustable state, the content of the data state column 617 can be “the air inlet being manually controlled”.
It can be understood that the input of one or more target values of temperature 611 and target position information 614 can be detected previously via the temperature detection unit 40 and the position detection unit 59.
It can be understood that one icon selected from the data latching icon 615 and the data adjusting icon 616 can be displayed in the display interface 61, when the icon is selected in an odd number frequency, the data state enters into the latched state, when the icon is selected in an even number frequency, the data state enters into the adjustable state, the disclosure is not limited herein.
In some embodiment, a reset icon 618 is displayed in the display interface 61. The operator can operate the interactive system 60 to select the reset icon 618. The control device 58 outputs reset information to the motor 571 in response to user operation on the reset icon 618, triggering the motor 571 to drive the sliding block 552 to move back to the starting position on the sliding rail 551.
It can be understood that when the motor 571 drives the sliding block 552 to move to the starting position on the sliding rail 551 according to the reset information, the position detection unit 59 detects the current position of the sliding block 552 in real time or at intervals. The control device 58 obtains the position detection information from the position detection unit 59 in real time or at intervals. The position detection information corresponds to the current position of the sliding block 552. The control device 58 analyzes the position detection information to determine whether the sliding block 552 moves to the starting position on the sliding rail 551. If the control device 58 determines that the sliding block 552 has moved to the starting position on the sliding rail 551, the control device 58 controls the motor 571 to stop working. If the control device 58 determines that the sliding block 552 has not moved to the starting position on the sliding rail 551, the control device 58 continuously controls the motor 571 to work and continuously obtains and analyzes the position detection information until the sliding block 552 reaches the starting position on the sliding rail 551. Thus, the reset of the sliding block 552 is completed.
In some embodiments, the system 100 can further include an alarm device 518. The alarm device 518 is communicatively coupled to the control device 58. The control device 58 outputs an alarm signal to the alarm device 518, to control the alarm device 518 to prompt the operator to manually operate a test or a production process on the working station 12.
In can be understood that a triggering condition that the control device 58 outputs the alarm signal can be that the device 50 cannot continue to test or process the product or the semi-finished product. At that moment, the operator needs to manually operate the test or the process on the working station 12.
For example, after the control device 58 obtains the target temperature information, if the control device 58 determines that the temperature of the environment where the working station 12 is located corresponding to the target temperature information is out of a temperature adjustment range of the device 50, the control device 58 outputs the alarm signal.
It can be understood that the alarm device 518 can be, but is not limited to, a buzzer, a warning light, or the like.
For example, if the alarm device 518 is a buzzer, the control device 58 outputs the alarm signal to the alarm device 518 to control the alarm device 518 to give an alarm.
In some embodiments, the alarm device 518 can be installed on the machine 10; in some embodiments, the alarm device 518 can be installed at a wall or floor of the environment where the system for automatic control of temperature 100 is located, the disclosure is not limited herein.
It can be understood that the device 50 can control the temperature of the working space 11 without the control device 58, the disclosure is not limited herein.
It can be understood that the air box 51 can define at least one opening 517 (see
The principle of the system 100 can be further illustrated by
In some embodiments, before processing the product or the semi-finished product, the operator can control the motor 571 to work via the control device 58, causing the baffle member 52 to move to the target position relationship information 619 one by one. The operator records the environmental temperature of the working station 12 via the temperature detection unit 40 one by one when the baffle member 52 moves to the target position relationship information 619 one by one. The operator can further record the number of pulses of the pulse voltage signal received by the motor 571 one by one when the baffle member 52 moves to the target position relationship information 619 one by one. The operator can further input the recorded environmental temperatures of the working station 12 and the recorded numbers of the pulses into the control device 58 via the interactive system 60, the control device 58 outputs the environmental temperatures of the working station 12 and the numbers of pulses employed to the interactive system 60, causing the interactive system 60 to display in the display interface 61.
After setting the relationship between the target values of temperature 611, the target position relationship information 619, and the target position information 614, the system 100 can automatically adjust the environmental temperature of the working station 12.
In some embodiments, the operator can determine the target environmental temperature of the working station 12 which needs to be reached according to a requirement of the environment of test or production. The operator can input the target temperature information to the control device 58 via the interactive system 60. The control device 58 analyzes the target temperature information, to determine whether the target environmental temperature of the working station 12 which needs to be reached is out of the temperature adjustment range of the device 50. If such target environmental temperature of the working station 12 is out of the temperature adjustment range of the device 50, the control device 58 controls the alarm device 518 to give the alarm.
If such target environmental temperature of the working station 12 is within the temperature adjustment range of the device 50, the control device 58 analyzes the target temperature information and the temperature detection information to determine the pulse number of the pulse voltage signal needing to output to the motor 571, and outputs the movement triggering signal to the motor 571 according to the pulse number. Thus, the motor 571 drives the sliding block 552 and the baffle member 52 to move, causing the baffle member 52 to move to the preset position, thus a covered area of the air inlet opening 515 can be adjusted, and the temperature of the working space 11 can be adjusted accordingly. Thus, the temperature of the environment where the working station 12 is located can be adjusted accordingly. In some embodiments, when the air inlet opening 515 is covered completely by the baffle member 52, the temperature of the working space 11 is the highest. When the air inlet opening 515 is completely not covered by the baffle member 52, the temperature of the working space 11 is the lowest.
Referring to
At step S61, the control device obtains target temperature information.
It can be understood that, the operator can input the target temperature information to the control device via the interactive system.
At step S62, the control device determines whether the target temperature information is out of a temperature adjustment range of the device for automatic control of temperature.
It can be understood that, the temperature adjustment range of the device for automatic control of temperature can be a temperature range capable of adjusting by the device for automatic control of temperature. In detail, a setting of the temperature adjustment range can refer to a temperature of the cooling air output from the air-conditioning system connecting to the device for automatic control of temperature, and a temperature of the environment where the system is located. The temperature adjustment range can be detected via the temperature detection unit previously by maintaining the temperature of the cooling air output from the air-conditioning system and maintaining the environmental temperature of the system.
For example, at a condition that the temperature of the cooling air output from the air-conditioning system is maintained and the environmental temperature of the system is maintained, when the baffle member convers the air inlet opening completely, the temperature of the working space detected by the temperature detection unit is 31° C. When the baffle member does not cover the air inlet opening, the temperature of the working space detected by the temperature detection unit is 26° C., thus the temperature adjustment range can be set to be a range of 26° C. to 31° C. previously.
For example, during testing or production of the product or the semi-finished product, when the temperature adjustment range is a range of 26° C. to 31° C., and the temperature of the working space detected by the temperature detection unit is 26° C., thus the control device determines that the target temperature information is out of the temperature adjustment range of the device for automatic control of the temperature.
At step S63, the control device outputs an alarm signal to an alarm device if the target temperature information is out of the temperature adjustment range of the device for automatic control of the temperature.
It can be understood that, if the target temperature information is out of the temperature adjustment range of the device for automatic control of the temperature, the test or the production of the product or the semi-finished product can not be completed in the system. At the moment, the alarm signal can be output to prompt the operator, for example prompt the operator to move the product and the semi-finished product to another system, or prompt the operator to adjust the temperature of the cooling air output from the air-conditioning system. Thus, the product and the semi-finished product can be continuously processed.
At step S64, the control device obtains temperature detection information from the temperature detection unit if the target temperature information is within the temperature adjustment range of the device for automatic control of the temperature.
A detail of obtaining temperature detection information from the temperature detection unit can be referred to the related description of the embodiment of the system, which will not be described herein.
At step S65, the control device determines whether the temperature of the working space corresponding to the temperature detection information is within a temperature range corresponding to the target temperature information.
It can be understood that, the target temperature information can correspond to a preset temperature range. The preset temperature range can be a temperature range whose center is the target temperature information.
For example, the target value of temperature selected by the operator is 29° C. in the display interface, thus the temperature corresponding to the target temperature information is 29° C. The target temperature information of 29° C. corresponding to a temperature range, for example, a temperature range of 28.5° C. to 29.5° C.
It can be understood that, in some embodiments, due to some reasons, for example, due to a flowing of the air, the temperature satisfying a requirement for testing or production of the product or the semi-finished product can be any value in the preset temperature range. Thus, when the environmental temperature of the working space corresponding to the temperature detection information is within the temperature range corresponding to the target temperature information, the temperature of the working space can satisfy the requirement for testing or production of the product or the semi-finished product, thus the temperature of the working station does not need to adjust.
At step S66, the control device outputs a movement triggering information to control a motor to rotate to bring the sliding block and the baffle member to move according to the temperature detection information and the target temperature information if the temperature of the working space corresponding to the temperature detection information is out of the temperature range corresponding to the target temperature information.
In some embodiments, a detail of outputting a movement triggering information to control a motor to rotate to bring the sliding block and the baffle member to move according to the temperature detection information and the target temperature information can be referred to the related description of the embodiment of the system, which will not be described herein.
At step S67, the control device obtains the position detection information from the position detection unit.
In some embodiments, a detail of obtaining the position detection information from the position detection unit can be referred to the related description of the embodiment of the system, which will not be described herein.
At step S68, the control device determines whether the sliding block has moved to the target position of the sliding block according to the position detection information and the target position information corresponding to the target temperature information.
It can be understood that, after a long time use, the motor, the synchronous belt, and the synchronous gears may have different wear conditions. When the motor rotates according to the received pulse voltage signal, a large difference may be existed between an actual movement distance of the synchronous belt and a preset movement distance. Whether there is the difference between the actual movement distance of the synchronous belt and the preset movement distance can be determined by comparing the position detection information with the preset position of the latching member.
It can be understood that, the sliding block and the baffle member are fixed via the second connecting member, thus when the sliding block has moved to the preset position of the sliding block, the baffle member also has moved to a desired position.
It can be understood that, whether the sliding block has moved to the preset position of the sliding block can be determined, by determining whether a different value of the pulse between the pulse number of the pulse voltage signal corresponding to the position detection information and the pulse number of the pulse voltage signal corresponding to the target position information is within a preset range. In some embodiments, the principle that each position detection information corresponds to one pulse number of the pulse voltage signal, and each target position information corresponds to one number of pulses of the pulse voltage signal can be referred to the related description of the embodiment of the system, which will not be described herein.
For example, the number of the pulses of the pulse voltage signal corresponding to the target position information can be 9000, the preset range can be a number of the pulses from −500 to 500, thus when the number of the pulses of the pulse voltage signal corresponding to the position detection information is within a range of 8500 to 9500, the sliding block has moved to the target position of the sliding block. It can be understood that, when the number of the pulses of the pulse voltage signal corresponding to the position detection information is within a range of 8500 to 9500, the baffle member also has moved to the desired position. When the number of the pulses of the pulse voltage signal corresponding to the position detection information is out of a range of 8500 to 9500, the sliding block has not already moved to the target position of the sliding block. It can be understood that, when the number of the pulses of the pulse voltage signal corresponding to the position detection information is out of a range of 8500 to 9500, the baffle member also has not moved to the desired position.
At step S69, the control device outputs an adjustment information to the motor to bring the sliding block to move toward a target position of the sliding block corresponding to the target temperature information continuously according to the position detection information and the target position information if the sliding block has not moved to the target position of the sliding block.
At step S610, the control device obtains the position detection information from the position detection unit again.
In some embodiments, during the motor moves the sliding block according to the adjustment information, the control device obtains the position detection information from the position detection unit again.
In some embodiments, after the motor moves the sliding block according to the adjustment information, the control device obtains the position detection information from the position detection unit again.
In some embodiments, a detail of obtaining the position detection information from the position detection unit again can be referred to the related description of the embodiment of the system, which will not be described herein.
At step S611, the control device determines whether the sliding block has moved to the target position of the sliding block again according to the position detection information obtained again and the target position information corresponding to the target temperature information.
A detail of determining whether the sliding block has moved to the preset position of the sliding block again can be referred description of the step S68, which will not be described herein.
At step S612, the control device continues outputting the adjustment information to the motor and determining whether the sliding block has moved to the target position of the sliding block until the sliding block has moved to the target position of the sliding block, if the sliding block has not moved to the target position of the sliding block.
For example, the target position of the sliding block is a position A, and the sliding block has moved to a position B, thus the control device determines that the sliding block has not moved to the target position of the sliding block. The control device continuously outputs the adjustment information to the motor to bring the sliding block to move toward the position A. The control device determines that the sliding block has moved to a position C, and determines that the sliding block has not moved to the target position of the sliding block. The control device outputs the adjustment information to the motor to bring the sliding block to move toward the position A again, and determines that the sliding block has moved to the position A. Thus, the control device determines that the sliding block has moved to the target position of the sliding block.
In can be understood that, the obtaining of the position detection information, the determining of whether the sliding block has moved to the target position of the sliding block, and the outputting of the adjustment information to the motor can be cycled if the sliding block has not moved to the target position of the sliding block. In some embodiments, the control device stops the outputting of the adjustment information to stop the rotating of the motor if the sliding block has moved to the target position of the sliding block.
At step S613, the control device continues obtaining the temperature detection information from the temperature detection unit again, and continues outputting the movement triggering information to control the motor and outputting the adjustment information to control the motor if needs, until a preset end condition is reached.
In some embodiments, the condition that the method performs the step S613 can be, for example, the temperature of the working space corresponding to the temperature detection information is within the temperature range corresponding to the target temperature information, or the sliding block has moved to the target position of the sliding block, or at preset intervals, or after a preset period of time after determining that the sliding block has moved to the target position of the sliding block, or after a preset period of time after determining that the temperature of the working space corresponding to the temperature detection information is within the temperature range corresponding to the target temperature information, or the like.
It can be understood that, during the test or production of the product or the semi-finished product, the control device can obtain the temperature detection information cyclically until the preset end condition is reached. And the controlling of the motor to bring the sliding block to move can be automatically according to a temperature change of the working station until the preset end condition is reached. The preset end condition can be, for example, the product or the semi-finished product has tested or produced completely, or an end signal is received via the interactive system by the operator, or the target temperature information has adjusted, or the like.
It can be understood that, after the test or production of the product or the semi-finished product, the control device can obtain a new target temperature information again, thus the control device can newly adjust the current temperature of the working space to the new target temperature information.
In this way, the method can automatically adjust the temperature of the working station.
