[0023] Specifically, the transverse pressure control drive assembly includes a first electric push rod 12 fixedly installed on the rear side of the box-shaped material receiving rack 1, and a first pressure sensor 13 is fixedly connected between the protruding end of the first electric push rod 12 and the left side of the movable plate 3, and the first pressure sensor 13 and the first electric push rod 12 are both electrically connected to the PLC controller 4; the first electric push rod 12 and the first pressure sensor 13 are arranged to cooperate, and the PLC controller 4 is used to control the first electric push rod 12 to start in the forward direction so that it drives the movable plate 3 to move right through the first pressure sensor 13. When the movable plate 3 moves to the right and can no longer move right, the first pressure sensor 13 detects the extrusion force and transmits the pressure value to the PLC controller 4. After reaching the preset pressure value, the PLC controller 4 controls the first electric push rod 12 to start in the reverse direction to move back and reset, thereby achieving the effect of pressure-controlled displacement to the right.

[0024] Furthermore, the front and rear pressure control drive components include a multi-stage electric push rod 10 fixedly installed on the rear side of the movable plate 3, the protruding end of the multi-stage electric push rod 10 extends into the rectangular hole 2 and is fixedly connected to the second pressure sensor 9, and the second pressure sensor 9 and the multi-stage electric push rod 10 are both electrically connected to the PLC controller 4; the multi-stage electric push rod 10 and the second pressure sensor 9 are coordinated, and the PLC controller 4 is used to control the multi-stage electric push rod 10 to start forward so that it drives the second pressure sensor 9 forward.

[0025] Furthermore, the elastic guide right push assembly includes four T-shaped guide rods 7 fixedly connected to the inner wall of the front side of the box-shaped push plate 6 in a rectangular shape, and the same L-shaped push plate 15 is slidably sleeved on the four T-shaped guide rods 7, wherein the rear side of the L-shaped push plate 15 is provided with four circular guide holes that are respectively in sliding contact with the outer sides of the corresponding T-shaped guide rods 7, which play a role in guiding the L-shaped push plate 15 to slide back and forth. A plurality of springs 8 are fixedly connected between the rear inner wall of the L-shaped push plate 15 and the front inner wall of the box-shaped push plate 6. The rear side is fixedly connected to the front side of the second pressure sensor 9, and a rectangular through hole 16 with an opening on the left side is provided on the front inner wall of the box-shaped push plate 6.

When the box-shaped push plate 6 moves forward to contact with the plate, it is blocked and restricted by it. The L-shaped push plate 15 that continues to move forward protrudes forward from the box-shaped push plate 6 and compresses the spring 8. The spring 8 in the compressed state gradually increases the force pushing the box-shaped push plate 6 forward, thereby achieving the pressure-controlled pushing of the plate forward. When the moving plate 3 is pressure-controlled and moved to the right, the multi-stage electric push rod 10 and the second pressure sensor 9 are sequentially driven to move the L-shaped push plate 15 to the right. The L-shaped push plate 15 drives the box-shaped push plate 6 to the right through the T-shaped guide rod 7. The L-shaped push plate 15 The protruding part of the plate is pushed to the right under controlled pressure, and the plate is automatically and comprehensively aligned by using the forward controlled pressure pushing and then the right controlled pressure pushing. The pressure value transmitted by the first pressure sensor 13 reaches the preset value, so that the PLC controller 4 controls the first electric push rod 12 to start and reset in the reverse direction, and then controls the multi-stage electric push rod 10 to start in the reverse direction to move back and reset, and restore the initial position. Then, it can continue to wait for the plate to be transported to the inside and then perform the aligning work again.

[0026] Furthermore, the photoelectric sensing switch includes an infrared emitter and an infrared receiving sensor 100 that cooperates with it. The infrared receiving sensor 100 is fixedly connected to the left front side of the box-shaped material collection rack 1, the infrared emitter is fixedly connected to the left rear side of the box-shaped material collection rack 1, and the infrared receiving sensor 100 is electrically connected to the PLC controller 4; the infrared receiving sensor 100 and the infrared emitter are used to cooperate to sense the passage of the plate, and the infrared receiving sensor 100 is used to transmit the start-up sorting signal to the PLC controller 4 after the plate passes.

[0027] Furthermore, a plurality of rollers 14 are rotatably installed on the front side of the box-shaped push plate 6, wherein a plurality of grooves are opened on the front side of the box-shaped push plate 6, and pins are fixedly connected to the top inner wall and the bottom inner wall of the groove. The top and bottom ends of the rollers 14 are fixedly connected to bearings, and the inner ring of the bearing is fixedly fitted on the outer side of the corresponding pin, which has the effect of rotatably installing the rollers 14. The friction between the rollers 14 and the plate can be reduced when the box-shaped push plate 6 moves to the right.

[0028] Furthermore, the rear side of the L-shaped push plate 15 is fixedly connected to two guide rods 11 located in the rectangular hole 2, and the movable plate 3 is slidably mounted on the two guide rods 11 to guide the guide rods 11 to slide back and forth.

[0029] The method of using this embodiment is as follows: according to the pushing pressure required for the plate to be neatly arranged, the PLC controller 4 is used to pre-set the reverse start-up pressure value of the first electric push rod 12 and the closing pressure value of the multi-stage electric push rod 10; when the plate is transported to the box-shaped material receiving rack 1 by the external plate conveying device, the infrared receiving sensor 100 and the infrared transmitter are used to sense the plate passing through, and the infrared receiving sensor 100 is used to transmit the start-up arrangement signal to the PLC controller 4 after the plate passes through; at this time, the PLC controller 4 first controls the multi-stage electric push rod 10 to start forward so that it drives the second pressure sensor 9 to move forward, and the second pressure sensor 9 drives the L-shaped push plate 15 When the plate is pushed forward, the L-shaped push plate 15 drives the box-shaped push plate 6 to move forward through the spring 8, and the box-shaped push plate 6 drives the roller 14 to move forward. The roller 14 pushes the plate forward. When it is pushed to the front side and cannot move forward further, the box-shaped push plate 6 is blocked and restricted. At this time, the L-shaped push plate 15 that continues to move forward protrudes forward from the box-shaped push plate 6 and compresses the spring 8. The spring 8 in the compressed state gradually increases the force pushing the box-shaped push plate 6 forward. The second pressure sensor 9 detects the extrusion force and transmits it to the PLC controller 4. When the preset pressure value is reached, the PLC controller 4 controls the multi-stage electric push rod 10 to automatically close, thereby achieving the effect of controlling the pressure and pushing the plate forward.

[0030] After the forward pushing pressure value reaches the preset value, the PLC controller 4 also controls the first electric push rod 12 to start forward, and the first electric push rod 12 drives the movable plate 3 to move to the right through the first pressure sensor 13. The movable plate 3 drives the L-shaped push plate 15 to move to the right through the multi-stage electric push rod 10 and the second pressure sensor 9 in turn. The L-shaped push plate 15 drives the box-shaped push plate 6 to move to the right through the T-shaped guide rod 7. The roller 14 is used to reduce the friction between the box-shaped push plate 6 and the plate when the box-shaped push plate 6 moves to the right. The protruding part of the L-shaped push plate 15 pushes the plate to the right. When the plate is pushed to the far right, it is blocked and restricted, so that the L-shaped push plate 15 is blocked and restricted and no longer moves to the right. At this time, the first pressure sensor 13 detects the pushing force applied by the first electric push rod 12 and transmits it to the PLC controller 4 pressure value. When the preset pressure value is reached, the PLC controller 4 controls the first electric push rod 12 to start in reverse to reset to the left. After controlling the first electric push rod 12 to start in reverse, the multi-stage electric push rod 10 is controlled to start in reverse to perform backward reset work, and then the plate material can continue to be transported to the inside and then the tidying work can be performed again, and finally all the plates are folded together; during the backward reset, the elastic force of the spring 8 in the compressed state drives the protruding part of the L-shaped push plate 15 to automatically retract into the box-shaped push plate 6, achieving the effect of automatically controlling the pressure to push the plate to the right after the forward control pressure is pushed, and the coordinated mode of controlling the pressure to push the plate to the right after the forward control pressure is pushed is utilized to achieve the effect of automatic and comprehensive tidying of the plate material when collecting the plate, which is convenient for automatic and tidying plate collection work. By automatically aligning the plate material, the phenomenon of uneven left and right, front and back of multiple plates is avoided, the neatness and aesthetics are improved, and the subsequent plate inspection and packaging work is facilitated, and additional damage such as exposure and folding of the plate material due to unevenness is avoided, and the demand for automatic and tidy plate collection is met.
