Description

Technical Field

[0001] This utility model relates to the technology in the field of silicone protective film production, and in particular to a folded OCA processing waste discharge production equipment. Background Technology

[0002] Silicone protective film is a protective film material that uses silicone as an adhesive. Silicone protective films typically have high transparency, clearly showcasing the appearance of the protected item. They maintain stable performance over a wide temperature range and will not peel or deteriorate due to temperature changes. Silicone protective films have a wide range of applications: they can protect electronic devices such as mobile phone screens, tablet screens, and camera lenses from scratches, dust, and dirt. They can also be used for protecting automotive paint and interior parts, preventing scratches and stains. Furthermore, they can be used for surface protection of home decoration materials such as glass, ceramics, and marble. In addition, silicone protective films can be used for surface protection of various mechanical equipment and instruments, preventing collisions and scratches during operation or transportation.

[0003] Silicone protective films are typically formed by laminating multiple layers of materials, such as OCA optical adhesive and high-viscosity adhesive layers. These adhesive materials are relatively thin. During manufacturing, multiple layers are usually laminated before being cut into bare pieces using a circular cutter. Due to the special properties (high viscosity) of adhesive materials such as OCA optical adhesive and high-viscosity adhesive layers, waste removal is difficult, resulting in defects such as easy breakage of adhesive edges, inability to pull the edges back up, adhesive pulling during waste removal, and bubbles forming at the edges of the waste product. These issues affect processing efficiency and easily lead to product quality defects. Therefore, it is necessary to research a solution to these problems. Utility Model Content

[0039] The working principle of this embodiment is described in detail below:

[0040] The pre-compression device 21, the first die-cutting device 22, the second die-cutting device 23, the third die-cutting device 24, the pressure device 25, the OCA raw film unwinding device 31, the single-layer silicone film unwinding device 41, the silicone protective film finished product winding device 42, the OCA release film winding device 51, the waste discharge PET film winding device 52, the high-viscosity raw film unwinding device 53, the waste material winding device 54, the release film unwinding device 55, and the edge material unwinding device 56 are all connected to an external control system. The external control system controls the pre-compression device 21, the first die-cutting device 22, the second die-cutting device 23, the third die-cutting device 24, the pressure device 25, the OCA raw film unwinding device 31, the single-layer silicone film unwinding device 41, the silicone protective film finished product winding device 42, the OCA release film winding device 51, the waste discharge PET film winding device 52, the high-viscosity raw film unwinding device 53, the waste material winding device 54, the release film unwinding device 55, and the edge material unwinding device 56 to work together.

[0041] First, the OCA pre-film 61 is unwound by the OCA pre-film unwinding device 31, and simultaneously, the single-layer silicone film 62 is unwound by the single-layer silicone film unwinding device 41. The OCA pre-film 61, after being superimposed on the upper surface of the single-layer silicone film 62, enters the pre-pressing device 21 together with the single-layer silicone film 62. The pre-pressing device 21 presses the OCA pre-film 61 and the single-layer silicone film 62. Next, the OCA release film 63 on the OCA pre-film 61 is separated and wound up by the OCA release film winding device 51. Then, the single-layer silicone film 62 and the OCA pre-film 61 with the OCA release film 63 removed enter the first die-cutting device 22, where the first die-cutting device 22 die-cuts the OCA pre-film 61 with the OCA release film 63 removed. Then, the high-viscosity pre-film unwinding device 53 unwinds the high-viscosity pre-film 64, causing the high-viscosity pre-film 64 to overlap with the OCA pre-film 61 with the OCA release film 63 removed. Film 61 is laminated and enters the second die-cutting device 23. At the same time, the waste PET film winding device 52 winds up the PET film 65 of the high-adhesion original film 64. Then, the second die-cutting device 23 performs OCA inner frame die-cutting, and the waste material winding device 54 winds up the waste material 66 generated by die-cutting. Then, the release film unwinding device 55 releases the release film 67, so that the release film 67 is laminated with the high-adhesion original film 64 from which the PET film 65 has been torn off and enters the third die-cutting device 24. Then, the third die-cutting device 24 performs finished outer frame die-cutting to obtain edge material 68 and finished silicone protective film 69. Then, the edge material 68 is wound up by the edge material unwinding device 56, and the finished silicone protective film 69 enters the pressing device 25 for pressing and output. Finally, the finished silicone protective film 69 is wound up by the finished silicone protective film winding device 42.

[0042] The key design feature of this invention is that by combining a pre-pressing device, a first die-cutting device, a second die-cutting device, a third die-cutting device, and a pressurizing device, the silicone protective film is die-cut multiple times during the production process. This ensures smooth processing, effectively removes OCA waste, improves processing efficiency, and reduces quality defects such as bubbles and glue residue on product edges, thus bringing convenience to production operations.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
