Description

Technical Field

[0001] The utility model relates to the technical field of composite copper foil, in particular to a composite copper foil release film structure. Background Art

[0002] At present, in order to solve the problem of laminating bubbles in the production process of flat-panel liquid crystal display (TLCM), the production process has been changed from assembling the backlight first and then laminating the cover plate to laminating the cover plate first and then assembling the backlight. The accompanying result is that the edge glue needs to be attached before laminating the cover plate; the design scheme of the composite copper foil in the terminal area adopts an integrated design, but the integrated design is completed after the composite material is attached at one time (sticking FPC / PCBA and BLU at the same time). If any defects related to BLU and composite materials are found, the composite material needs to be torn off first, then the BLU is disassembled, and finally the CG is disassembled, and the new composite material is replaced simultaneously. The disassembly process is complicated and inefficient. Utility Model Content

[0021] The embodiment of the present application provides a composite copper foil release film structure, which effectively solves the problem that if defects related to the BLU and the composite material are found in the existing integrated composite copper foil after pasting, the composite material needs to be torn off first, then the BLU is disassembled, and finally the CG is disassembled, and a new composite material is replaced simultaneously, and the disassembly process is complicated and inefficient.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that if the BLU and the composite material are found to be defective after the existing integrated composite copper foil is pasted, the composite material needs to be torn off first, then the BLU is disassembled, and finally the CG is disassembled, and the new composite material is replaced simultaneously, and the disassembly process is complicated and the efficiency is low. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a composite copper foil release film structure, including a front protective film 3, the front protective film 3 is provided with a protective film cutting line 4, the front protective film 3 is cut into a removable protective film 7, the removable protective film 7 is connected to a second protective film tearing handle 6, the back side of the front protective film 3 is connected to a transparent base film 1, the transparent base film 1 is provided with a base film cutting line 2, and the base film cutting line 2 cuts the transparent base film 1 into two second base films 8.

[0024] The two second bottom films 8 are of different sizes, and the removable protective film 7 is connected to two second protective film tearing hands 6, so that the removable protective film 7 can be torn off on both sides after installation.

[0025] A protective film integral tearing handle 5 is arranged on the side of the front protective film 3 away from the transparent base film 1, and the protective film integral tearing handle 5 can tear off the transparent base film 1 as a whole. A docking piece 9 is arranged between the transparent base film 1 and the front protective film 3 for bonding the transparent base film 1 and the front protective film 3.

[0026] A segmented setting is adopted, and the removable protective film 7 can be separated when the protective film cutting line 4 is cut, and the second base film 8 can be separated when the base film cutting line 2 is cut, so that the composite material can be attached twice, the first time to stick to the FPC / PCBA and then proceed to the subsequent process. After the finished product is electrically tested and found to be ok, the removable protective film 7 and the second base film 8 of the composite material are torn off, and the transparent base film 1 and the front protective film 3 are used to stick to the BLU.

[0027] Working principle:

[0028] In the first step, a segmented setting is adopted. The removable protective film 7 can be separated when the protective film cutting line 4 is cut, and the second base film 8 can be separated when the base film cutting line 2 is cut, so that the composite material can be attached twice. The first time, the FPC / PCBA is adhered and then the subsequent process is carried out. After the finished product is electrically tested and there is no problem, the removable protective film 7 and the second base film 8 of the composite material are torn off, and the transparent base film 1 and the front protective film 3 are used to adhere the BLU.

[0029] In the second step, if BLU and composite material related defects are found after the first pasting, the removable protective film 7 can be torn off through the second protective film tearing hand 6, and then the second bottom film 8 can be torn off from the transparent bottom film 1. It will not affect the transparent bottom film 1 and the front protective film 3, and will not involve the disassembly of the CG, which greatly optimizes the disassembly process and improves the working efficiency.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
