Abstract
Description
Technical Field
[0001] The present invention relates to a processing technology, and particularly to a processing technology for adding a mesh to foam Background Art
[0002] The bonding of cameras in electronic products such as mobile phones, tablet computers, and laptop computers is usually achieved by using high-performance double-sided tapes. Such high-performance double-sided tapes need to have properties such as high bonding strength, excellent impact resistance, good anti-curved surface tension, and excellent push-out force.
[0003] As consumers' requirements for electronic products are getting higher and higher, the performance requirements for the camera bonding tape are also getting higher and higher. The tape not only plays a role in protecting the camera but also is one of the essential auxiliary components for improving the photo-taking effect. The existing process is to produce the inner and outer frames separately with a flat knife in a nested position, and there are many defects in the large and small sides, and the production yield is low, which affects the occurrence of defects such as deviation and wall climbing during the automatic fitting of the product.

[0007] 2) Use a round knife to punch and cut the transparent original film between the second processing stations. All the cross-breaking knives are semi-cut to the bottom film, and the rest of the inner lining knives are semi-cut to the protective film; the waste of the transparent original film is discharged;
[0008] 3) At the third processing station, attach the foam surface of the foam to the adhesive surface of the protective film;
[0009] 4) At the fourth processing station, attach one side of the double-sided tape to the PET surface of the foam and peel off the self-adhesive paper of the double-sided tape;
[0010] 5) Between the fourth processing station and the fifth processing station, attach the first matte release film to the other side of the double-sided tape;
[0011] 6) At the fifth processing station, use a round knife to punch and cut the first matte release film. The inner frame is semi-cut to outside the protective film, and the outer frame is semi-cut to the bottom film; discharge the peripheral foam and the waste of the first matte release film;
[0012] 7) At the sixth processing station, use masking tape to extract the waste of the first matte release film on the surface of the odd-numbered rows of inner holes;
[0013] 8) At the seventh processing station, use masking tape to extract the waste of the first matte release film on the surface of the even-numbered rows of inner holes;
[0014] 9) At the eighth processing station, attach the transparent tape to the other side of the double-sided tape and the first matte release film, and discharge the foam waste in the middle of the inner hole and the waste of the first matte release film in the effective adhesive area;
[0015] 10) At the tenth processing station, attach the second matte release film to the other side of the double-sided tape, use a round knife to punch and cut the second matte release film, and the strip knife is semi-cut to the bottom film; discharge the waste of the strip at both ends and the second matte release film, and after peeling off the bottom film, wind the finished product inward.
[0016] In a preferred embodiment, the finished product is, from top to bottom, a protective film, a foam, a double-sided tape, and a second matte release film. Description of the Drawings
