[0075] +HRC-P60A30 protective film / 30;

[0076] Process:

[0077] 1. Die-cutting: In the inkjet room, spray the silicone treatment agent evenly on one side of the 60-degree silicone raw material, use a hair dryer to dry the treatment agent and roll it up (note that double-sided tape must be attached within 24 hours after spraying the treatment agent). Spraying the silicone treatment agent on the silicone raw material effectively solves the problem that ordinary double-sided tape cannot stick to silicone directly. Therefore, only after the silicone is sprayed with the treatment agent, the double-sided tape can stick to it;

[0078] 2. The die-cutting and laminating machine gently sticks TESA61335 black double-sided tape / 124 on the side of the 60-degree silicone sprayed with the treatment agent, and rewinds;

[0079] 3. Die-cutting: In the inkjet room, evenly spray the unbonded silicone with silicone treatment agent, use a hair dryer to dry the treatment agent and roll it up (the silicone treatment agent has a time limit, and the amount of treatment sprayed must be evaluated and the manual work must be completed within 24 hours), and the warehouse is cut into 20mm / roll;

[0080] 4. Use a circular knife to stick the adhesive side of the MY3806B silicone protective film / 75 to the black side of the breathable film (the rubber shaft of the circular knife cannot directly contact the white side of the breathable film, and must be wrapped with clean release paper), stick the DA004 protective film on the back of the blue protective film, and cut the strips and half of the circular knife onto the DA004 protective film. Roll up the blue silicone protective film together with the breathable film (note that the hands should not touch the white side of the breathable film during the whole process);

[0081] 5. Die cutting reference Figure 1 The first cut is die-cut while fitting. For the specific cutting method, see the first cut schematic diagram on the right;

[0082] 6. Die cutting and second cutting (note that the peripheral waste should not be removed) Figure 2 , the cutting machine cuts 60 PCS / sheet (the first and second cuts are operated inline, and the second cutter cannot be padded with foam), and the peripheral waste is not removed to ensure the position of the silicone semi-finished product and the positioning hole, and to ensure the quality of the subsequent manual assembly. If the peripheral waste is discharged, the waste will definitely pull the silicone semi-finished product during the waste discharge process, causing the position of the silicone semi-finished product and the positioning hole to change;

[0083] 7. Die cutting reference Figure 3 The third step is to cut the laminating materials in the laminating layer diagram, die-cut while laminating, and the die-cutting machine discharges the peripheral waste. After the sealing tape sticks off the DC022W white release film waste, the whole DC022W white release film is laminated (note that the product cannot be shifted on the release film). Its function is to immediately discharge the pieces of white inner film waste to prevent long-term placement.

[0084] The double-sided adhesive overflows to the side section of the white release film. When the white release film is removed, the double-sided adhesive will be removed together. At the same time, replacing the whole white release film can also improve the efficiency of the subsequent manual work. The third cut is made on the basis of the semi-finished product.

[0085] 8.Reference Figure 4 , die cutting, set cutting, fourth cutting, waste cleaning knife, waste cleaning, and winding;

[0086] 9. The die-cutting and laminating machine will laminate the black surface of the AYN-M80T02 breathable film onto the blue silicone protective film (hands should not touch the white effective surface of the breathable film. During the process, only the clean rubber shaft of the laminating machine can touch the white effective surface of the breathable film. Other things should not touch the white effective surface of the breathable film). Cut the breathable film surface. For specific cutting methods, see reference. Figure 5 After the laminating machine discharges the waste of breathable film, it rolls up the whole sheet of DC022W white release film. The colored silicone protective film has a backing adhesive, so that the breathable film can be attached to the blue silicone film. The backing adhesive is a weak adhesive.

[0087] 10. Die cutting reference Figure 6The sixth cutting is to laminate the materials (note: the non-release surface of the blue release film is laminated to the P60A30 protective film), and die-cut while laminating. For the specific cutting method, see the sixth cutting diagram on the right. The peripheral waste cannot be removed. There is a weak adhesive backing on the blue release film, and the P60A30 protective film is laminated together through the adhesive on the blue isolation film.

[0088] 11. Manually assemble the semi-finished products (dust-free workshop operation) and transfer the products to the DC035 transparent release film (engineering follow-up). Specifically, refer to the manual assembly hierarchy diagram. Figure 7 Specifically, the three layers below are semi-finished products obtained by the first cut, and the two layers above are semi-finished products obtained by the fifth cut. The two layers of double-sided adhesive sandwiched breathable film in the middle are obtained by cutting the breathable film on the blue silicone protective film through the fifth cut. At the same time, positioning holes are cut on the blue protective film. The breathable film is manually transferred to the double-sided adhesive accurately by the positioning holes of the blue protective film, and then the weakly sticky silicone protective film is torn off. After the air film is accurately transferred to the double-sided adhesive, the weakly sticky silicone protective film is torn off.

[0089] The product was transferred to the DC035 transparent release film. Specifically, the first and second cut silicone semi-finished products were replaced with the DC035 transparent release film. The purpose was to make it easier for customers to take the product from the DC035 transparent release film. The blue release film of the silicone semi-finished product was tightly bonded to the double-sided adhesive, making it difficult to take it directly.

[0090] 12. Screen print and bake the breathable film (62℃, 1 hour). The purpose of baking is to activate the double-sided adhesive quickly and stick the breathable film tightly to achieve the purpose of waterproof tuning.

[0091] 13.CCD full inspection (dust-free workshop operation);

[0092] The holes at the four corners of the first to fifth cut strips are positioning holes for cooperation with the manual assembly jig;

[0093] The outer periphery of the semi-finished product from the second to the fifth cut is half-cut, and the hole is fully cut;

[0094] The first to fifth cuts are not rolled up, and are all sliced;

[0095] The process steps of manual assembly are assembled sequentially according to the assembly level;

[0096] The old die-cutting process is to fit the material strips together as if they were assembled by hand, and then die-cut the shape at one time. The bruises of the old die-cutting process are the places where the blades cut, which are obviously uneven and have concave wrinkles.

[0097] The semi-finished product cut out by the third cut is a three-layer cylindrical structure. The third cut is to cut a hole in the middle of the double-sided tape. The airflow passes through the breathable membrane through the hole to achieve the tuning effect. This hole is concentric with the silicone hole cut in the first cut, and is available for manual assembly.

[0098] 1. Each delivery must be accompanied by a 10mm*10mm size silicone raw material for customer testing;

[0099] 2. QC conducts a full inspection of the finished product in the dust-free workshop with the help of a CCD magnifying glass (a flat lamp needs to be placed on the CCD base in advance). Both the front and back sides of the product need to be inspected to confirm that the circular breathable membrane mesh has no glue overflow, no hair or dust, no broken wires, no perforations, and the upper and lower circular holes are as concentric as possible (the outline of the black silicone must not be blocked, and the boundaries must be clear and clearly visible).

[0100] When using a circular knife to slit the breathable film, please note:

[0101] 1) The force of the breathable film discharge shaft should not be too large;

[0102] 2) When the reel retracts the breathable film, it should be retracted together with the blue protective film to avoid excessive force from the reel reel.

[0103] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The first cut is to cut the silicone surface, cut all the holes, and clean the waste with a waste cleaning knife; S6, die-cutting sets cut the silicone surface, cut the second cut, and the peripheral waste of the second cut is not removed. The cutting machine cuts the sheets, and the first and second cuts are operated online. The second cut peripheral knife cannot be padded with foam. The peripheral waste is not removed to ensure the position of the silicone semi-finished product and the positioning hole after the first and second cuts, and to ensure the quality of the subsequent manual assembly; if the peripheral waste is discharged, during the waste discharge process, when the waste pulls the silicone semi-finished product, it will cause the position of the silicone semi-finished product and the positioning hole to change, and the size and peripheral size of the hole to the four sides of the product are measured by IPQC; S7, the laminating machine laminates the black double-sided tape on the PET blue release film / RC-8050L, and replaces the original paper of the black double-sided tape with the DC022W white release film. Die-cutting is performed while laminating. The third cut is to cut the surface of the DC022W white release film, and the holes are completely cut. The die-cutting machine discharges the peripheral waste, and the sealing tape sticks off the waste of the DC022W white release film, and then the whole sheet of DC022W white release film is laminated. S8, based on the third cut semi-finished product, the fourth cut is made, the die-cutting set is used to cut the DC022W white release film surface, the holes are completely cut, the waste is removed by the waste removal knife, and the roll is rolled up. The IPQC measures the size of the holes to the four sides of the product and the outer dimensions to obtain the double-sided adhesive semi-finished product; S9, the die-cutting and laminating machine laminates the black surface of the breathable film onto the blue silicone protective film, cuts the fifth cut, cuts the breathable film surface, and after the laminating machine discharges the waste of the breathable film, laminates the whole white release film and rolls it up to obtain a semi-finished breathable film; S10, the die-cutting and laminating machine laminates the protective film on the non-release surface of the blue release film, cuts the release surface of the blue release film for the sixth time, and cuts all the holes to obtain a blue hand-tearable semi-finished product; S11, manually assemble the semi-finished products in a dust-free workshop. Specifically, the three lower layers are the silicone semi-finished products obtained by the second cutting, the two upper layers are the blue hand-tearable semi-finished products obtained by the sixth cutting, and the three middle layers are two layers of double-sided adhesive with a layer of breathable film sandwiched between them. The double-sided adhesive is the double-sided adhesive semi-finished product obtained by S8, and the breathable film is the breathable film semi-finished product obtained by S9. Meanwhile, positioning holes are cut on the blue silicone protective film of the breathable film semi-finished product in S9. The manual personnel use the positioning holes of the blue silicone protective film to accurately transfer the breathable film of the breathable film semi-finished product to the double-sided adhesive semi-finished product of S8, and then tear off the blue silicone protective film. Further, the product is transferred to the transparent release film; S12, screen printing and baking products; S13, perform CCD full inspection in the dust-free workshop.
