[0002] In the production of mobile phone screen module, in order to maximize screen ratio, low pressure injection liquid silicone molding technology is adopted to accurately shape the screen middle frame. This process requires liquid silicone to be directly formed on the glass substrate, and after forming, the liquid silicone and the glass substrate need to be efficiently separated. To achieve this goal, the traditional method is to attach a layer of film on the surface of the glass substrate as an auxiliary layer for subsequent separation. After processing, this layer of film can be easily peeled off, facilitating the recycling of the glass substrate.

[0003] The existing film attachment method is to cover the film on the glass substrate manually, and then flatten it with a scraper. This process relies on manual operation, which not only consumes time and effort, increases production cost, but also inevitably leads to insufficient alignment accuracy of the film and the glass substrate, thereby affecting the quality and efficiency of subsequent processing.

[0004] Therefore, there is a need for a film attachment fixture to solve the above problems. SUMMARY

[0005] The utility model aims at providing a film attachment fixture to reduce the traditional manual film attachment process, significantly improve the alignment accuracy of the film attachment, and improve the film attachment efficiency and quality.

[0037] The existing film attaching method is that the film is covered on the glass substrate manually, and then is scraped flat by a scraper, which depends on manual operation, not only consumes time and effort, increases production cost, but also inevitably appears the case that the alignment precision of the film and the glass substrate is insufficient, thereby affecting the quality and efficiency of subsequent processing.

[0038] To solve the above problems, such as Figures 1-3As shown, the embodiment provides a film pasting jig. The film pasting jig comprises a placing plate 1 and a positioning assembly 2. The placing plate 1 is provided with a placing cavity 11, and a workpiece can be placed in the placing cavity 11. The positioning assembly 2 is arranged on the placing plate 1. The positioning assembly 2 comprises a plurality of first positioning members 21. The film comprises a pasting part and a positioning part. A plurality of first positioning holes are arranged on the positioning part. The film is placed on the workpiece. The plurality of first positioning holes correspond to the plurality of first positioning members 21 one by one. The pasting part of the film is aligned with the surface of the workpiece. The placing plate 1 provides a stable support platform. When the film is covered on the workpiece, the plurality of first positioning holes on the positioning part of the film are arranged on the plurality of first positioning members 21 one by one, so that the pasting part of the film is accurately aligned with the surface of the workpiece. Then, the air between the film and the workpiece is discharged by using a scraper, and the film pasting is completed. The film pasting is assisted by using the film pasting jig. The traditional manual film pasting process is reduced. The alignment accuracy of the film pasting is significantly improved. The subsequent processing quality problem caused by inaccurate alignment of the film is avoided. The film pasting efficiency and quality are improved.

[0039] In the embodiment, as shown in the drawings, Figure 1 The positioning assembly 2 is located at one end of the length direction of the placing cavity 11.
