A drive cylinder 51 is provided on one side of the negative pressure seat 5 to connect to an air pump to distribute air pressure changes.

[0033] The sorting module further includes a first transfer platform 6 and a second transfer platform 7. The first transfer platform 6 is located on one side of the conveyor platform 2, and a transfer suction block 61 driven by a conveyor belt is mounted on the first transfer platform 6. The bottom surface of the transfer suction block 61 has several ventilation holes, and the transfer block is connected to a gas pressure pipeline, which is connected to the ventilation holes. The transfer block is used to absorb the cut film slices and transport them to the second transfer platform 7 via the conveyor belt of the first transfer platform 6. During transportation, a quality inspection module is installed at the workbench 1 below the first transfer platform 6 to perform quality inspection and rating on the film slices being transferred.

[0034] The second transfer platform 7 is disposed on one side of the first transfer platform 6, and is arranged in the direction corresponding to the conveyor platform 2. A transport frame 71 is provided on the second transfer platform 7. The bottom of the transport frame 71 is driven by a conveyor belt.

An adsorption block at the bottom of the transfer head 81 is equipped with an adsorption nozzle, which is controlled by an air pressure pipeline and used to adhere to the adhesive film slices. The branch conveyor platform 9 at the tail of the adsorption block is a belt-driven conveyor. The two sets of branch conveyor platforms 9 are symmetrically arranged and lead to different target areas for further processing.

[0036] Processing procedure: The conveyor roller 21 feeds the adhesive film to be processed to the negative pressure seat 5, where it reaches the desired position. The negative pressure seat 5 generates negative pressure to fix the protruding adhesive film to the upper surface. The cutting blade 31 cuts the adhesive film and then resets. The cleaning mechanism moves to spray and wipe the cutting edge of the cutting blade 31. The lower slag discharge hole 47 collects waste liquid to prevent splashing and affecting the adhesive film.

[0037] Simultaneously, the transfer suction block 61 picks up the cut film sheet, and the negative pressure seat 5 returns to normal pressure. The transfer suction block 61 performs optical inspection on the cut film sheet, which is a conventional technique in the field and will not be described in detail here. The transfer suction block 61 places the inspected film sheet on the transport rack 71 and moves it to below the transfer head 81. Based on the inspection results, the transfer head 81 transports film sheets of different qualities to different branch conveyor tables 9 according to controller instructions. The branch conveyor tables 9 can be adjusted in number and orientation according to processing requirements.
