The mechanical arm 61 is electrically connected with the first identification mechanism 30 and the second identification mechanism 50. The assembling member 62 is drivingly connected with the mechanical arm 61 to move under the driving of the mechanical arm 61. The suction assembly 63 is arranged on the assembling member 62. The suction assembly 63 is used to take the film from the feeding mechanism 40 and drive the film to move to the position corresponding to the second identification mechanism 50 under the driving of the assembling member 62, and is used to paste the film on the film pasting position according to the film pasting position and the position of the film on the suction assembly 63.

[0055] Specifically, since there are errors in the production process and the positioning process of the product, there are also errors in the process of taking the film by the suction assembly 63, thereby causing the film pasting to be inaccurate. By setting the specific structure of the film pasting mechanism 60, in the film pasting process, the mechanical arm 61 performs corresponding error compensation according to the film pasting position of the product identified by the first identification mechanism 30 and the position of the film on the suction assembly 63 identified by the second identification mechanism 50, and then drives the suction assembly 63 to move to make the suction assembly 63 paste the film on the film pasting position of the product, thereby improving the accuracy of pasting the film on the product.

[0056] Please refer to Figure 8 In the embodiment, the suction assembly 63 is a plurality of suction assemblies 63, which are arranged on the assembling member 62 at intervals. The film pasting mechanism 60 further includes a plurality of moving driving members 64. Each of the plurality of moving driving members 64 can be a telescopic cylinder. The plurality of moving driving members 64 are arranged on the assembling member 62 at intervals and correspond to the plurality of suction assemblies 63 one by one.

[0057] Each suction assembly 63 comprises a sliding piece 631, a suction piece 632, a pressure sensor 633, a plug-in piece 634 and a buffer elastic piece 635. The sliding piece 631 is slidingly arranged on the assembling piece 62 and is drivingly connected with the corresponding moving driving piece 64, so as to be close to or away from the mechanical arm 61 under the driving of the corresponding moving driving piece 64. The suction piece 632 can be a vacuum suction head, and the suction piece 632 is slidingly arranged on the assembling piece 62 and located on the side of the sliding piece 631 away from the mechanical arm 61. The pressure sensor 633 is arranged at one end of the sliding piece 631 close to the suction piece 632. The plug-in piece 634 is slidingly arranged in the suction piece 632 and is connected with the pressure sensor 633. The buffer elastic piece 635 can be a spring, and the buffer elastic piece 635 is sleeved on the plug-in piece 634, and the two ends of the buffer elastic piece 635 are connected with the sliding piece 631 and the suction piece 632 respectively.

[0058] When the film piece is taken out from the feeding mechanism 40 by the film pasting mechanism 60, the suction pieces 632 of the plurality of suction assemblies 63 can simultaneously suck the film piece from the feeding mechanism 40. When the film piece is attached to the product, the plurality of suction assemblies 63 independently paste the film, and when one suction assembly 63 pastes the film, the other moving driving pieces 64 drive the corresponding sliding pieces 631 to move, and the sliding pieces 631 drive the suction pieces 632 to approach the mechanical arm 61 through the plug-in pieces 634 to avoid the product. In this way, the plurality of suction assemblies 63 can sequentially attach the plurality of film pieces to different positions of the product or attach the plurality of film pieces to a plurality of products, thereby reducing the time required for taking the film and improving the film pasting efficiency. In addition, the arrangement of the pressure sensor 633 facilitates real-time monitoring of the pressure of the suction piece 632 when pasting the film, avoiding overpressure of the film piece and the product by the suction piece 632, and the arrangement of the buffer elastic piece 635 enables the suction piece 632 to flexibly abut against the product when pasting the film, thereby reducing the probability of crushing the product.

The jacking driving piece 723 is used to drive the pressure maintaining piece 721 to separate from the film piece.

[0062] When the pressure maintaining film tearing mechanism 70 presses the film piece, the plurality of pressure maintaining weights 722 apply pressure to the pressure maintaining piece 721, and the pressure maintaining end 7211 of the pressure maintaining piece 721 presses the film piece against the product. After the pressure maintaining is completed, the jacking driving piece 723 drives the pressure maintaining piece 721 to separate from the film piece. Since the plurality of pressure maintaining weights 722 are detachably arranged on the mounting end 7212 of the pressure maintaining piece 721, the number of the pressure maintaining weights 722 can be adjusted according to the required pressure maintaining pressure, and the pressure provided by the pressure maintaining weights 722 has high accuracy, thereby improving the accuracy of the pressure maintaining assembly 72 in pressing the film piece against the product.

[0063] In this embodiment, the pressure maintaining assembly 72 can be multiple, thereby facilitating the pressure maintaining of the film pieces attached to different positions of the product at the same time.

The movable clamping arm 733 is used to move relative to the fixed clamping arm 731 under the driving of the clamping driving piece 732, so that the first clamping portion 7311 and the second clamping portion 7331 clamp or release the cover film.

[0065] When the film tearing assembly 73 tears the cover film from the bottom film, the moving assembly 71 drives the film tearing assembly 73 to approach the cover film, the clamping driving piece 732 drives the movable clamping arm 733 to move relative to the fixed clamping arm 731, the first clamping portion 7311 and the second clamping portion 7331 clamp the cover film, and then the moving assembly 71 drives the film tearing assembly 73 to move away from the bottom film, and the cover film is separated from the bottom film under the driving of the first clamping portion 7311 and the second clamping portion 7331. In this way, the structure of the film tearing assembly 73 is simple, and the accuracy of tearing the cover film from the bottom film is improved.

[0066] In some other embodiments, the clamping driving member 732 can also be arranged on the mounting member 74 and drivingly connected with the movable clamping arm 733, and the present application does not make a specific limitation in this regard.

[0067] In the present embodiment, the pressure maintaining and film tearing mechanism 70 further comprises a guide member 75 and a collecting member 76. The guide member 75 is mounted on the conveying assembly 21 and is provided with a guide hole 751. The collecting member 76 can be a collecting bag and is arranged on the guide member 75 and opposite to the guide hole 751. After the film tearing assembly 73 tears the cover film from the bottom film, the moving assembly 71 drives the film tearing assembly 73 to move above the guide member 75, the first clamping portion 7311 and the second clamping portion 7331 release the cover film, and the cover film falls into the guide hole 751 and then into the collecting member 76 under the guidance of the guide hole 751. In this way, the cover film torn by the film tearing assembly 73 can be conveniently collected.

The second linear module 813 can be a double-mover linear motor. The connecting seat 814 is drivingly connected with the second linear module 813 to move in the horizontal direction under the driving of the second linear module 813. The detection module 82 and the re-pressing assembly 83 are arranged on the connecting seat 814. In this way, the moving assembly 81 has a simple structure and improves the accuracy of driving the detection module 82 and the re-pressing assembly 83 to move.
