step S11: the lifting plate 14 is reset after material taking;
specifically, the main control module 30 drives the motor mechanism 12 to rotate through the driving module 40, and the lifting plate 14 moves to a material taking reset point under the transmission of the transmission mechanism 13; after the lifting plate 14 moves to the material taking reset point, a plurality of stacked sheet materials 900 can be placed on the lifting plate 14 for automatic material taking and placing equipment or manual one by one taking in and taking out in the subsequent process; specifically, whether the lifting plate 14 moves to the material taking reset point or not can be confirmed through the position data record of the main control module 30 and the sent displacement, and in other embodiments, the lifting plate 14 can be confirmed to reset according to the signal of the material taking origin sensor 84; further, after the lifting plate 14 reaches the material taking reset point, the main control module 30 may output an origin return completion signal to the automatic material taking and placing device; to ensure that the lifter plate 14 reaches the material-taking reset point, the main control module 30 sends an origin return completion signal to perform a delay operation, so as to provide a proper moving time for the lifter plate 14.
Step S12: the lifter plate 14 moves upward;
specifically, the main control module 30 drives the motor mechanism 12 to rotate through the driving module 40, and the lifting plate 14 moves upward while the sheet material 900 stacked on the lifting plate 14 moves upward by the transmission of the transmission mechanism 13.
Step S13: the first fiber optic transmission assembly and first fiber optic amplifier 62 identifies whether the sheet material 900 has passed through the pick-and-place station;
specifically, when the sheet material 900 starts to generate a shield between the first emission detecting head 611 and the first reception detecting head 612, the first identification signal generates a rising edge, and when the first identification signal generates a rising edge, the operation is performed as in step S14.
Step S14: the lifter plate 14 moves downward;
specifically, after the first identification signal generates a rising edge, the main control module 30 drives the motor mechanism 12 to rotate through the driving module 40, and the lifting plate 14 moves downward while the sheet material 900 stacked on the lifting plate 14 moves downward under the transmission of the transmission mechanism 13.
Step S15: the first fiber optic transmission assembly and first fiber optic amplifier 62 identifies whether the sheet material 900 has reached a critical position for the pick-and-place station;
specifically, when the sheet material 900 reaches the pick-and-place station critical position, the sheet material 900 just stops shielding between the first emission detecting head 611 and the first receiving detecting head 612, and the first identification signal generates a falling edge.
Step S16: the lifting plate 14 stops moving;
specifically, after the lifting plate 14 stops moving, automatic material taking and placing equipment or manual hand can conveniently take materials from the topmost sheet material 900; further, in order to inform the automatic material taking and placing device to perform material taking operation, after the lifting plate 14 stops moving, the main control module 30 outputs a material taking waiting signal to the automatic material taking and placing device.
Step S17: the main control module 30 determines whether the material taking operation is completed;
specifically, in order to prepare for taking the next sheet material 900, after the top sheet of the stacked sheet materials 900 is taken, the top sheet material 900 of the next sheet material 900 is adjusted in time, the main control module 30 determines whether the taking operation is completed or not by the action sensing signal of the material moving sensor 70 or the externally input taking completion signal, and the taking completion signal may be input to the main control module 30 by an automatic material taking and placing device or may be input to the main control module 30 by a manual button operation; further, after the main control module 30 confirms that the material taking operation is completed, the lifting platform system operates again according to the steps S12 to S17, so that the automatic material taking and placing equipment or a human hand can take the sheet material 900 layer by layer accurately from the critical position of the material taking and placing station each time, and the automatic material taking and placing equipment such as a manipulator can complete the material taking operation accurately.
Referring to fig. 7, the operation method of the lifting platform system in the discharging process includes the following steps:
step S21: the lifting plate 14 carries out emptying and resetting;
specifically, the main control module 30 drives the motor mechanism 12 to rotate through the driving module 40, and the lifting plate 14 moves to the discharging reset point under the transmission of the transmission mechanism 13; after the lifting plate 14 moves to the discharging reset point, the lifting plate 14 is close to the material taking and placing station, so that in the subsequent process, automatic material taking and placing equipment or manual hand can stack the sheet materials 900 piece by piece; specifically, whether the lifting plate 14 moves to the discharging reset point can be confirmed through the position data record of the main control module 30 and the sent displacement, and in other embodiments, the lifting plate 14 can be confirmed to reset according to the signal of the discharging origin sensor 85; further, after the lifting plate 14 reaches the material discharging reset point, the main control module 30 may output an origin return completion signal to the automatic material discharging and taking device; when the lifting plate 14 moves to the discharging reset point, the lifting plate 14 is in the material taking and placing station, and the first optical fiber transmission assembly and the first optical fiber amplifier 62 recognize the lifting plate 14; to ensure that the lifting plate 14 reaches the discharging reset point, the main control module 30 sends an origin return completion signal to perform a delay operation, so as to provide a proper moving time for the lifting plate 14.
Step S22: the lifter plate 14 moves downward;
specifically, the main control module 30 drives the motor mechanism 12 to rotate through the driving module 40, and the lifting plate 14 moves downward while the sheet material 900 stacked on the lifting plate 14 moves downward by the transmission of the transmission mechanism 13.
Step S23: the first fiber optic transmission assembly and first fiber optic amplifier 62 identifies whether the lifter plate 14 or sheet material 900 has reached a pick-and-place station threshold;
specifically, when the lifting plate 14 or the sheet material 900 stops shielding between the first emission detection head 611 and the first reception detection head 612, the first identification signal generates a falling edge; the first identification signal generates a falling edge when the elevator plate 14 or topmost layer of stacked sheet material 900 just reaches a critical position for the pick-and-place station.
Step S24: the lifting plate 14 stops moving;
specifically, after the lifting plate 14 stops moving, automatic material taking and placing equipment or manual labor can conveniently carry out material placing operation on the topmost sheet material 900; further, in order to inform the automatic material taking and placing device to perform material placing operation, after the lifting plate 14 stops moving, the main control module 30 outputs a material placing waiting signal to the automatic material taking and placing device.
Step S25: the main control module 30 determines whether the discharging operation is completed;
specifically, in order to prepare for the next discharging of the sheet material 900, after the top sheet of the stacked sheet materials 900 is discharged, the lifting plate 14 is moved in time, and the new top sheet material 900 is adjusted in time, the main control module 30 determines whether the discharging operation is completed through the action sensing signal of the material moving sensor 70 or the discharging completion signal input from the outside, and the discharging completion signal can be input to the main control module 30 by the automatic material taking and placing device or can be input to the main control module 30 by the manual button operation; further, after the main control module 30 confirms that the material taking operation is completed, the lifting platform system operates again according to the steps from S22 to S25, so that the automatic material taking and placing equipment or a human hand can accurately place the sheet material 900 layer by layer from the critical position of the material taking and placing station each time, and the automatic material taking and placing equipment such as a manipulator can accurately complete the material placing operation.
