Then, the first X-axis linear module 312, the first Y-axis linear module 313, and the first Z-axis linear module 314 work together to deliver the product to the designated position on the coating mechanism 3. At the same time, the first rotary cylinder 315 rotates the product horizontally, in this embodiment by 90 degrees, so that the product's length is aligned with the X-axis and its length is aligned with the Y-axis.

[0039] Furthermore, the coating assembly 36 includes a height adjustment assembly 361, a first pressure roller 362, and a second pressure roller 363.

The distance between the first pressure roller 362 and the conveyor belt assembly 33 is less than the thickness of the product, so that the first pressure roller 362 and the second pressure roller 363 can apply pressure to the upper electrostatic film, the product, and the lower electrostatic film through the elasticity of their own materials. The height adjustment component is fixedly installed on the second conveyor frame 331, and the movable end of the height adjustment component is connected to the first pressure roller 362 to adjust the height of the first pressure roller 362. The height adjustment assembly 361 includes an adjustment frame and an adjustment screw. The adjustment frame is fixedly connected to the second conveyor frame 331, and the adjustment screw is threadedly connected to the adjustment frame. At the same time, the adjustment screw is rotatably connected to the first pressure roller 362 so that the rotation of the adjustment screw can drive the first pressure roller 362 to move along the Z direction. Each first pressure roller 362 corresponds to two height adjustment components 361, and the surfaces of the first pressure roller 362 and the second pressure roller 363 can be made of rubber.

[0040] The cutting assembly 37 includes a belt 371 and a flying knife 372. The belt 371 is driven by a motor, and the belt of the belt 371 is connected to the flying knife 372, which facilitates the driving of the flying knife 372 to move along the Y direction and cut the upper and lower electrostatic film that have been squeezed by the coating assembly 36, so that the coated product becomes an independent state.

[0041] A first transverse module 38 is mounted on the frame 1. The movable end of the first transverse module 38 is connected to the laminating frame 32 so as to drive the laminating mechanism 3 to move along the Y direction. The first transverse module 38 can be a linear module.

[0043] Specifically, the rejection mechanism 4 includes a lifting assembly 41 and a first blocking assembly 4224 mounted on the first conveyor roller assembly 21. The movable end of the first blocking assembly 4224 extends to block product conveying, and the movable end of the lifting assembly 41 extends to lift the product. The structure of the first blocking assembly 4224 is the same as that of the second blocking assembly, and will not be described again here. The lifting assembly 41 includes a second telescopic cylinder 411 and a lifting plate 412. The second telescopic cylinder is fixedly connected to the first conveyor frame 211, and the movable end of the second telescopic cylinder is fixedly connected to the lifting plate 412.

[0044] The defective product collection mechanism 5 includes a gripping component 51, a transfer conveying component 52, a product handling component 53, a tray handling component 54, and a tray positioning component 55. The gripping component 51 is used to grip and convey defective products rejected by the rejection mechanism 4 to the transfer conveying component 52. The transfer conveying component 52 is used to receive and transport defective products rejected by the rejection mechanism 4. The tray positioning component 55 is used to place the tray. The product handling component 53 is used to transport the products conveyed by the transfer conveying component 52 onto the tray.

[0045] Specifically, the material gripping assembly 51 includes a second Y-axis linear module 511, a third telescopic cylinder 512, a fourth telescopic cylinder 513, and a second suction cup 514.

The movable end of the second Y-axis linear module 511 is fixedly connected to the third telescopic cylinder 512, the movable end of the third telescopic cylinder 512 is fixedly connected to the fourth telescopic cylinder 513, and the movable end of the fourth telescopic cylinder 513 is fixedly connected to the second suction cup 514. During operation, the second suction cup 514 picks up defective products from the lifting plate 412 and then transports the products to the intermediate conveying assembly 52. ​​Due to the different heights of the lifting plate 412 and the intermediate conveying assembly 52, only the third telescopic cylinder 512 works when gripping defective products on the lifting plate 412; when placing defective products on the intermediate conveying assembly, both the third telescopic cylinder 512 and the fourth telescopic cylinder 513 work.

[0046] The intermediate conveying assembly includes a second conveyor roller assembly 521 and a second belt conveyor assembly 522. The second conveyor roller assembly 521 is perpendicular to the first conveyor roller assembly 21, while the second belt conveyor assembly 522 is parallel to the first conveyor roller assembly 21. The second conveyor roller assembly 521 receives defective products from the two first conveyor roller assemblies 21 and conveys them to the second belt conveyor assembly 522. A third blocking assembly is fixedly installed on the second belt conveyor assembly 522 to block defective products from being transported by the product handling assembly 53.

[0047] The structure and function of the product handling assembly 53 are similar to those of the gripping assembly 51, so they will not be described in detail here. The difference is that the gripping assembly 51 only moves defective products in the X and Z directions, while the product handling assembly 53 can move defective products in the X, Y, and Z directions.

[0048] The tray conveying assembly 54 includes a conveying frame 541 and an empty tray conveying assembly 543, a full tray conveying assembly 543, a first lifting member 544, a second lifting member 545, and a tray conveying member 546, all mounted on the conveying frame 541.

The tray conveying member 546 is used to move trays from the tray positioning assembly 55 above the empty tray conveying assembly to the tray positioning assembly 55 above the full tray conveying assembly 543. The second lifting mechanism corresponds to the full tray conveying assembly 543 to convey full trays from the tray positioning assembly 55 above the full tray conveying assembly 543 to the full tray conveying assembly 543.

[0049] Specifically, the empty tray conveying assembly and the full tray conveying assembly 543 can employ belt conveyor mechanisms, as long as they are capable of conveying trays. The first lifting member 544 includes a second Z-axis linear module 5441 and two lifting rods 5442. The second Z-axis linear module 5441 is fixedly connected to the transport frame 541, and the movable end of the second Z-axis linear module 5441 is fixedly connected to the two lifting rods 5442. The lifting rods 5442 are used to lift empty trays from the empty tray conveying assembly. The structure of the second lifting member 545 is the same as that of the first lifting member 544, but the second lifting member 545 is used to place full trays onto the full tray conveying assembly 543.

[0050] More specifically, the tray transport component 546 includes a second X-axis linear module 5461, a fifth telescopic cylinder 5462, and a third suction cup 5463. The second X-axis linear module 5461 is fixedly connected to the transport frame 541. The movable end of the second X-axis linear module 5461 is fixedly connected to the fifth telescopic cylinder 5462. The movable end of the fifth telescopic cylinder 5462 is fixedly connected to the third suction cup 5463. The third suction cup 5463 is used to adsorb the tray on the tray positioning component 55.

[0051] The tray positioning assembly 55 includes two sixth telescopic cylinders 551. The movable ends of the sixth telescopic cylinders 551 are fixedly connected to positioning rods 552 for placing the tray. When the movable ends of the two sixth telescopic cylinders 551 extend, the two positioning rods 552 can support the tray. The vertical projections of the two lifting rods 5442 are located between the two positioning rods 552 to prevent interference.

[0052] During operation, the gripping assembly 51 grips the defective products rejected by the rejection mechanism 4 and conveys them to the transfer conveyor assembly 52. ​​The transfer conveyor assembly 52 receives the defective products rejected by the rejection mechanism 4 and conveys them. Subsequently, the product handling assembly 53 moves the products to the tray of the tray positioning assembly 55 above the empty tray conveyor assembly. When the tray becomes full, the tray handling component 546 transfers the full tray to the tray positioning assembly 55 above the full tray conveyor assembly 543, and the second lifting component 545 moves the full tray to the full tray conveyor assembly 543. Simultaneously, the empty tray conveyor assembly conveys empty trays, which are then moved by the first lifting component 544 to the tray positioning assembly 55 above the empty tray conveyor assembly.

[0053] Working principle: The receiving mechanism 2 receives the products from the previous process and conveys them. The coating mechanism 3 receives the good products from the products conveyed by the receiving mechanism 2 and coats them.
