[0040] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0041] Please see Figures 1 to 8 The present invention provides a molding module for an easily separable flexible film, comprising a conveying base 5 and a first molding component 1, a second molding component 2, a third molding component 3 and a fourth molding component 4 arranged sequentially along the conveying direction. The first molding component 1, the second molding component 2, the third molding component 3 and the fourth molding component 4 are all located above the conveying base 5.

[0042] The first forming component 1 includes a first cutting mold 11, a contour film feeding device 12, and a first bonding device 13. The first cutting mold 11 and the first bonding device 13 are arranged sequentially along the conveying direction, and the contour film feeding device 12 is arranged close to the first bonding device 13.

[0043] The first cutting mold 11 includes a first cutter holder 100, a first outer frame cutter 101, and a first inner frame cutter 102. The first outer frame cutter 101 and the first inner frame cutter 102 are both disposed on the first cutter holder 100. The height of the first outer frame cutter 101 protruding from the first cutter holder 100 is greater than the height of the first inner frame cutter 102 protruding from the first cutter holder 100. The first outer frame cutter 101 is spaced apart from the conveying base 5.

[0044] The second molding component 2 includes a second cutting mold 21, a double-sided adhesive feeding device 22, and a second bonding device 23. The second cutting mold 21 and the second bonding device 23 are arranged sequentially along the conveying direction, and the double-sided adhesive feeding device 22 is arranged close to the second bonding device 23.

[0045] The second cutting die 21 includes a gap cutter 202, which is located at the edge of the second cutting die 21;

[0046] The fourth forming component 4 includes a fourth cutting mold 41, a carrier film feeding device 42, and a fourth bonding device 43. The fourth cutting mold 41 and the fourth bonding device 43 are arranged sequentially along the conveying direction, and the carrier film feeding device 42 is arranged close to the fourth bonding device 43.

[0047] Specifically, in this embodiment, the first forming component 1 is used for bonding and forming the protective film 94 and the contour film 93. Preferably, the protective film 94 includes multiple layers of PET protective film and one layer of PET base film. The multiple layers of PET protective film are stacked sequentially from top to bottom. The PET base film is located on the upper surface of the multiple layers of PET protective film. The first cutting die 11 includes a first cutter 100, a first outer frame cutter 101 and a first inner frame cutter 102. The first outer frame cutter 101 processes the outer contour of the protective film 94, that is, it cuts the multiple layers of PET protective film and one layer of PET base film with the overall thickness, so that the outer contour of the protective film 94 becomes a preset shape. The first inner frame cutter 102 processes the one layer of PET base film, that is, the first inner frame cutter 102 only cuts the outer contour of the PET base film. Then the waste is discharged to complete the processing and production of the protective film 94. The contour film feeding device 12 feeds the external contour film 93 to the top of the conveying base 5. Under the action of the first bonding device 13, the external contour film 93 and the protective film 94 are bonded.

[0048] The second forming component 2 includes a second cutting mold 21, a double-sided adhesive feeding device 22, and a second bonding device 23. The second cutting mold 21 cuts the combination of the contour film 93 and the protective film 94. The second cutting mold 21 includes a gap cutter 202, which is located at the edge of the second cutting mold. The gap cutter 202 cuts the edge of the contour film 93 to form a gap strip, which isolates the internal stress within a unit area of ​​the contour film 93, thereby reducing the adhesive force between the contour film 93 and the protective film 94. This avoids the phenomenon that the adhesive force between the protective film 94 and the contour film 93 will tear the contour film 93 off together during the process of tearing the protective film 94. The double-sided adhesive feeding device 22 feeds the external double-sided adhesive 92 to the top of the conveying base 5. Under the action of the second bonding device 23, the external double-sided adhesive 92, the contour film 93, and the protective film 94 are bonded together, wherein the double-sided adhesive 92 is bonded to the contour film 93.

[0049] The third molding component 3 cuts the inner contour of the product after the double-sided adhesive 92, the contour film 93 and the protective film 94 are bonded together.

[0050] The fourth forming component 4 includes a fourth cutting die 41, a carrier film feeding device 42, and a fourth bonding device 43. The fourth cutting die 41 cuts the outer contour of the product after the double-sided adhesive 92, the contour film 93, and the protective film 94 are bonded together. Then, the carrier film feeding device 42 transports the external carrier film to the top of the conveying base 5. Under the action of the fourth bonding device 43, the carrier film 91 and the double-sided adhesive 92, the contour film 93 and the protective film 94 are bonded together.

[0051] By setting up a first forming component 1, a second forming component 2, a third forming component 3, a fourth forming component 4, and a conveying base 5, the outer protective film 94, the contour film 93, the double-sided adhesive 92, and the carrier film 91 are sequentially processed, formed, and bonded. The second forming component 2 is equipped with a gap cutter 202 to cut the outer protective film 94 into gap strips, thereby removing internal stress and reducing the adhesive force between the protective film 94 and the contour film 93. This prevents the contour film 93 from being torn off during the process of peeling off the protective film 94, thus meeting the requirements of subsequent processing and production.

[0052] The first cutter holder 100 is cylindrical, the first outer frame cutter 101 is a closed ring, and the first inner frame cutter 102 is a closed ring. The first inner frame cutter 102 is located inside the first outer frame cutter 101. An external driving source drives the cylindrical first cutter holder 100 to rotate, so that the first outer frame cutter 101 and the first inner frame cutter 102 sequentially contact the external protective film to complete the cutting process.

[0053] The second cutting die 21 includes a second cutter holder 200 and a small hole cutter 201. The small hole cutter 201 and the gap cutter 202 are both disposed on the second cutter holder 200. The height of the small hole cutter 201 protruding from the second cutter holder 200 is less than the height of the gap cutter 202 protruding from the second cutter holder 200. The gap cutter 202 is spaced apart from the conveying base 5. There are two small hole cutters 201, which are located on both sides of the gap cutter 202. The small hole cutter 201 cuts the protective film, further reducing the adhesion between the protective film 94 and the contour film 93, and preventing the contour film 93 from being torn off during the process of peeling off the protective film 94.

[0054] The second cutter holder 200 is cylindrical, and the small hole cutter 201 and the gap cutter 202 are spaced apart. An external drive source drives the cylindrical second cutter holder 200 to rotate, so that during the process of the conveying base 5 conveying the protective film 94 and the conformal film 93, the small hole cutter 201 and the first inner frame cutter 102 sequentially contact the external protective film 94 to complete the processing purpose.

[0055] The third forming component 3 includes a third cutter holder 300 and a pre-forming cutter assembly 301. The pre-forming cutter assembly 301 is disposed on the third cutter holder 300, and the pre-forming cutter assembly 301 is spaced apart from the conveying base 5.

[0056] The third cutter holder 300 is cylindrical, and the pre-forming cutter assembly 301 is closed. An external driving source drives the cylindrical third cutter holder 300 to rotate, so that during the process of the conveying base 5 conveying the protective film 94 and the contour film 93, the pre-forming cutter assembly 301 sequentially contacts the combination of the external protective film 94 and the contour film 94 to complete the processing purpose.

[0057] The fourth forming component 4 includes a fourth tool holder 400 and a forming tool assembly 401. The forming tool assembly 401 is disposed on the fourth tool holder 400 and is spaced apart from the conveying base 5. The fourth tool holder 400 is equipped with the forming tool assembly 401. An external driving source drives the fourth tool holder 400 to rise and fall, so that the forming tool assembly 401 moves closer to or further away from the conveying base 5 to complete the processing of the carrier film 91.

[0058] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
