[0031] As an optimal technical solution, an upper support roller and a lower support roller are respectively arranged on the upper and lower parts of the circular knife roller of the third die-cutting mechanism, and the hand-tearing film and the hand-tearing film carrying protective film are roll-die-cut between the circular knife roller and the upper support roller, and the waste hand-tearing film and the hand-tearing film carrying protective film are roll-bonded with the mesh and the double-sided adhesive tape between the circular knife roller and the lower support roller.

[0033] As a preferred technical solution, a release film is provided on the lower surface of the mesh product, and a shipping protective film is provided on the upper surface of the mesh product.

[0034] A die-cutting method for mesh products that improves material utilization is produced using the die-cutting system, and specifically includes the following steps:

[0035] (1) The first release film unwinding roller releases the first release film, and the double-sided adhesive tape is released by the double-sided adhesive unwinding roller. The double-sided adhesive tape is attached to the upper part of the first release film and is rolled and die-cut by the first die-cutting mechanism to punch out the outline of the reserved area of ​​the long strip double-sided adhesive tape of the mesh product;

[0036] (2) The double-sided adhesive release paper winding roller reels the release paper waste on the surface of the double-sided adhesive;

[0037] (3) The waste tape unwinding roller releases the waste tape, and the waste tape rewinding roller rewinds the waste tape, and removes the release paper waste remaining on the double-sided adhesive reserved area of ​​the mesh product;

[0038] (4) The mesh unwinding roller releases the mesh material tape and attaches the mesh material tape to the upper part of the double-sided adhesive tape. The mesh material tape is then rolled and die-cut by the second die-cutting mechanism to punch out the mesh outline. The mesh waste material tape is then rolled up by the mesh waste winding roller (7). At the same time, the PET film unwinding roller releases the PET film, and the PET film is rolled up onto the adhesive surface of the mesh waste material tape. The residual adhesive waste on the mesh is then removed by tearing off the PET film, and the mesh waste is reused for a second time.

[0039] (5) The tearing film unwinding roller releases the tearing film, the tearing film carrying protective film unwinding roller releases the tearing film carrying protective film, the tearing film and the tearing film carrying protective film are laminated by the laminating mechanism and then pass through the third die-cutting mechanism to punch out the outline of the tearing film, the tearing film waste winding roller rewinds the tearing film waste material strip, and the discharged tearing film and the tearing film carrying protective film are rolled and laminated with the semi-finished product material strip of the step by the third die-cutting mechanism;

[0040] (6) the first release film winding roller winds up the first release film with the die-cutting marks;

[0041] (7) The second release film unwinding roller releases the second release film and adheres the second release film to the bottom of the product strip;

[0042] (8) The tearing film carrying protective film reel reels up the tearing film carrying protective film;

[0043] (9) The shipping protective film unwinding roller releases the shipping protective film and attaches it to the upper surface of the product material strip, and the product winding roller winds up the final product.

[0044] The principle of the present invention is to solve the serious waste problem of mesh waste by improving the mesh product die-cutting system and process. When the mesh waste winding roller reels up the mesh waste material strip, the non-product area of ​​the mesh outer frame is lifted up. Since the double-sided adhesive has a light adhesion to the release film and a strong adhesion to the mesh, the waste adhesive of the outer frame will remain on the waste material outside the mesh and cannot be directly used. Otherwise, it will cause misalignment. The waste adhesive is on the back of the mesh and is difficult to visually confirm. There is a certain probability that the finished product will have two layers of adhesive, which is a defective product that is difficult to identify and will cause the entire roll of products to be scrapped.

[0045] The present invention is provided with a PET film unwinding roller, which releases the PET film, and the PET film is rolled into the adhesive surface of the mesh waste material belt, and then the residual adhesive waste on the mesh is removed by tearing off the PET film, and the mesh with the residual adhesive removed is placed on the original mesh unwinding shaft, and a product distance is staggered during bonding, so as to achieve a high utilization rate of the mesh waste material and reduce enterprise costs.

[0046] In addition, this application can also solve the problems of low pass rate and low efficiency of mesh products during die-cutting processing through the design of the die-cutting mechanism and the positions of the winding and unwinding rollers of each material strip, as well as the process design of the waste discharge process after die-cutting. Compared with the traditional early sample preparation using flat knife production, the semi-finished products of mesh and adhesive backing and the semi-finished products of the tear-off protective film need to be manually assembled and bonded using a jig. The present invention uses a die-cutting system, through three-step punching, and successively through the waste discharge and the bonding sequence of each material strip, to achieve the automated die-cutting production of the product, which can reduce manual intervention, improve production capacity and quality, effectively reduce labor costs, shorten product production cycles, speed up production rhythm, and improve production capacity.

[0081] like Figure 1, is a mesh product that needs to be processed. It is specifically used in mobile phones. The middle part is mesh, the upper part is a tear-off protective film, and the lower part is double-sided tape. The product is designed as a single-sided mesh with partial adhesive backing, and the surface is attached with a handle for easy assembly. The lower surface of the mesh product is provided with a release film, and the upper surface of the mesh product is provided with a shipping protective film.

[0082] The current method for processing and manufacturing this product is that the early stage of sample making uses a flat knife for production, which results in a high product defect rate, and the semi-finished products of the mesh and adhesive backing and the semi-finished products of the hand-tear protective film need to be manually assembled and bonded using a jig, which not only leads to low efficiency, but also the problems of high product defect rate and low processing efficiency are never effectively solved.

[0083] In particular, the product currently requires a shipping arrangement such as Figure 4 As shown, if the required layout method is used directly, the product arrangement is too sparse, the process material utilization rate is very low, which will greatly increase the product production cost, especially the waste of mesh material tape is relatively serious.

[0084] In order to solve the above-mentioned technical problems, the present application provides the following solutions: the present invention improves the existing punching system and punching process steps, and solves the problems of low qualified rate and low efficiency of mesh products during die-cutting processing by improving the die-cutting system and process of mesh products. At the same time, a layer of transparent PET film 16 is rolled into the glue surface of the mesh waste, and then the glue waste on the mesh is removed by tearing off this layer of transparent PET film, and then the mesh with the residual glue removed is reused, and a product distance is staggered during bonding. At this time, the material utilization rate of the mesh is greatly improved.

[0085] The key to this application lies in the design of the die-cutting mechanism and the positions of the winding and unwinding rollers of each material strip, as well as the process design of the waste discharge process after die-cutting.

[0110] The specific steps include:

[0111] 1. The first release film unwinding roller 1 releases the first release film, and the double-sided adhesive unwinding roller 2 releases the double-sided adhesive tape. The double-sided adhesive tape is attached to the upper part of the first release film, and is rolled and die-cut by the first die-cutting mechanism 400 to punch out the outline of the reserved area of ​​the long strip double-sided adhesive of the mesh product, such as Figure 5As shown, the first die-cutting mechanism 400 is used to cut out the double-sided adhesive as shown in the figure below, and the waste is discharged and the reserved area is left. At this time, the semi-finished product level is: Figure 5 Fishbone-shaped double-sided adhesive tape and a transparent release film for fixing the position and bearing;

[0112] 2. Double-sided adhesive release paper reel 3 reels the release paper waste on the double-sided adhesive surface;

[0113] 3. The waste tape unwinding roller 4 releases the waste tape, and the waste tape rewinding roller 5 rewinds the waste tape, and removes the release paper waste remaining on the double-sided adhesive reserved area of ​​the mesh product;

Since the double-sided adhesive has a light adhesion to the release film and a strong adhesion to the mesh, the waste adhesive of the outer frame will remain on the waste material outside the mesh. Fig. 9 It is the waste mesh generated after the product is made. The waste glue on the back of the mesh needs to be removed before use. Otherwise, it can be directly reused. If the alignment is not accurate and the waste glue is on the back of the mesh, it is difficult to visually confirm.

The PET film unwinding roller 16 releases the PET film, and the PET film is rolled into the glue surface of the waste mesh material strip. The residual glue waste on the mesh is then removed by tearing off the PET film, and the waste mesh is reused. Fig.10 , the mesh that has been cleaned of residual glue will be reused in the original second step, and a product distance will be staggered during bonding, thus achieving a high utilization rate of the mesh waste material and reducing enterprise costs.

The tearing film and the tearing film carrying protective film are laminated by the laminating mechanism 300 and then pass through the third die-cutting mechanism 600 to punch out the outline of the tearing film, such as Figure 8 The tearing film waste reel 10 reels the tearing film waste material strip, and the tearing film after waste discharge and the tearing film carrying protective film are rolled and laminated with the semi-finished material strip of step 4 by the third die-cutting mechanism 600;

[0116] 6. The first release film winding roller 11 winds up the first release film with the die-cutting marks;

[0117] 7. The second release film unwinding roller 12 releases the second release film and attaches the second release film to the bottom of the product strip;

[0118] 8. The tearing film carrying protective film reel 13 reels up the tearing film carrying protective film;
