Method for plating flexible thin film on resin film

Abstract

The invention discloses a method for plating a flexible thin film on a resin film. The method comprises the following steps that 1, the peripheral edge of the resin film is clamped through a special jig; the jig comprises a bottom frame and an upper frame, a plurality of magnets are arranged on a frame on the periphery of the bottom frame, the frame of the upper frame is buckled on a frame of the bottom frame through the magnets, and the bottom frame and the upper frame jointly clamp the peripheral edge of the resin film. Step 2, uniformly distributing the thickness of a flexible film to be plated to two surfaces of the resin film, and respectively performing film plating by adopting a specific ion source auxiliary process; and 3, the frame of the upper frame is taken down from the frame of the bottom frame, and the resin film plated with the flexible film is taken down. According to the invention, double-sided coating is carried out on the blue-light glass, so that the effect of single-sided coating is achieved, the optical effect is met, and the problems of overlarge stress and overlarge warping caused by a relatively thick single-sided coating film layer are solved.

Description

Technical Field

[0001] The invention relates to a resin film coating method, in particular to a method for coating a flexible film on a resin film. Background Art

[0002] Resin film 1 is a new type of material designed and developed to address the limitations of blue glass material in terms of fragility and thickness, while maintaining the original optical properties of blue glass material. It has a thickness of 0.11mm and is now widely used in high-end mobile phone series products.

[0003] At present, it is also necessary to plate a flexible film 2 on one side of the resin film 1 (see Figure 1 ), but because the resin film material is a flexible material, the supporting strength is not enough, and the conventional processing technology cannot meet the production needs. In addition, the thickness of the resin film prepared by the conventional processing technology is relatively thick, which will cause problems such as excessive stress and excessive warping. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for coating a flexible film on a resin film using a special fixture in view of the above-mentioned technical problems existing in the existing single-sided coating on a blue glass material.

[0005] The technical problem to be solved by the present invention can be achieved by the following technical solutions:

[0006] A method for coating a flexible film on a resin film comprises the following steps:

[0007] Step 1: clamp the edges of the resin film using a special jig; the jig includes a bottom frame and an upper frame, a plurality of magnets are arranged on the frames around the bottom frame, the frame of the upper frame is buckled on the frame of the bottom frame through the magnets, and the bottom frame and the upper frame jointly clamp the edges of the resin film;

[0008] Step 2: Divide the thickness of the flexible film to be plated into two surfaces of the resin film and plate them separately using a specific ion source assisted process; the specific ion source assisted process is shown in the following table:

[0009]

[0010] Step 3: Remove the upper frame from the bottom frame, and take out the resin film coated with the flexible film.

[0011] In a preferred embodiment of the present invention, gaskets are arranged between the bottom frame, the upper frame and the blue light glass.

[0012] Due to the adoption of the above technical solution, the present invention adopts the frame of the upper frame to be buckled on the frame of the bottom frame through the magnet, and the bottom frame and the upper frame jointly clamp the edges of the resin film, saving the time of clamping the resin film with a jig and improving the efficiency. In addition, the double-sided coating of the resin film achieves the effect of single-sided coating, which not only meets the optical effect, but also solves the problems of excessive stress and excessive warping caused by the thick film layer of the single-sided coating.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] A method for coating a resin film on a resin film of the present invention comprises the following steps:

[0024] Step 1: See Figures 2 to 8 , a special fixture is used to clamp the edges of the resin film 1; the fixture includes a bottom frame 10, an upper frame 20 and two gaskets 30, a plurality of magnets 11 are arranged on the frame around the bottom frame 10, the frame of the upper frame 20 is buckled on the frame of the bottom frame 10 through the magnets 11, and the bottom frame 10 and the upper frame 20 jointly clamp the edges of the resin film 1; when clamping, gaskets 30 are arranged between the bottom frame 10 and the upper frame 20 and the resin film 1.

[0025] Step 2: The thickness of the flexible film 2a to be plated is evenly distributed to the two surfaces of the resin film 1, and the film is plated respectively using a specific ion source assisted process; the specific ion source assisted process is shown in the following table:

[0026]

[0027]

[0028] Step 3: After coating, the upper frame 10 is removed from the lower frame 20, and the resin film 1 coated with the flexible film 2a is taken out. Figure 7 , and achieved the effect of single-sided coating, which not only met the optical effect, but also solved the problems of excessive stress and warping caused by the thick single-sided coating layer.
