[0040] Reference Figure 1As shown, since the adhesive film is pierced by the tooth tip, the adhesive film waste will remain on the surface or side of the support platform 5. In order to clean the support platform 5, a waste pushing assembly connected to the support platform 5 is also included. The waste pushing assembly includes a pusher 7 and a second driver 12. The second driver 12 is preferably a cylinder. The second driver 12 drives the pusher 7 along the first direction X. The pusher 7 is located above the support platform 5 and is used to push off the adhesive film waste on the upper surface of the support platform 5. The pusher 7 is also located on both sides of the support platform 5 along the second direction Y and is used to push off the adhesive film waste stuck to the side of the support platform 5. Alternatively, in another embodiment, the second driver 12 drives the pusher 7 along the second direction Y. The pusher 7 is located above the support platform 5 and on both sides of the support platform 5 along the first direction X. The technical effect is the same as above and will not be repeated.

[0041] Reference Figure 1 As shown, in order to fully push off the adhesive film waste, the pusher 7 includes a first pusher plate 9 and a second pusher plate 14 connected together. In this embodiment, the first pusher plate 9 extends along the first direction X and is disposed near the upper surface of the support platform 5.

Specifically, the guide post 20 passes through a guide hole in the mounting base 2 and is locked by a screw. One end of the elastic element 19 abuts against the pressure plate 18, and the other end abuts against the mounting base 2. Before cutting begins, the first drive... Device 4 drives mounting base 2 to descend, pressure plate 18 presses on the adhesive film to ensure the adhesive film is flat, spring is compressed to buffer pressure plate 18 to prevent pressure plate 18 from damaging the adhesive film, and blade 3 continues to descend to puncture the adhesive film; further, the lower surface of the guide post 20 is fixed with a flexible plate 25, preferably polyurethane or urethane adhesive, which can use flexible contact to press and flatten the adhesive film, and both pressure plate 18 and flexible plate 25 are provided with clearance holes 21 facing the rectangular blade edge.

[0048] Reference Figure 1 As shown, since the adhesive film waste generated during cutting may stick to the blade 3 and affect the cutting, the mounting base 2 has multiple air holes 28 arranged in an array on the inner side of the rectangular cutting edge. The air holes 28 blow high-pressure gas downward to blow off the adhesive film waste on the blade 3.

[0049] Reference Figure 1 As shown, in order to achieve different cutting effects, the blade 3 includes a first blade 3 and a second blade 3. The opposite sides of the first blade 3 gradually approach the center line to form the tooth tip 27. The tooth tip 27 pierces the adhesive film from the middle of the cutting point and pierces the adhesive film from the middle to both sides. The second blade 3 has one side gradually approaching its opposite side to form the tooth tip 24. The tooth tip 24 pierces the adhesive film from one side of the cutting point and pierces the adhesive film from the other side.

[0052] The working principle of the film cutting machine with square punch blade described in this utility model is as follows:

[0053] After the suction cup 17 picks up a piece of adhesive film, the drive mechanism moves the machine platform 1 directly above the support platform 5. The suction cup 17 releases the adhesive film onto the support body 10 and the support block 11. Then, the first driver 4 presses down the blade 3 and the pressure plate 18. The pressure plate 18 presses the adhesive film tightly onto the support body 10 and the support block 11. The elastic element 19 contracts, and the blade 3 continues to pass through the clearance hole 21 to pierce the adhesive film, cutting out square adhesive film holes on the adhesive film. Then, the suction cup picks up the cut adhesive film. The first driver 4 drives the pressure plate 18 and the blade 3 to rise, and the drive mechanism removes the adhesive film. The third driver 8 drives the support block 11 to descend to the pushing height. The second driver 12 drives the push block to extend and clean the surface of the support block 11. After the push block 7 finishes cleaning, it retracts, and the support block 11 rises to the initial height.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
