Embodiment 1

[0039] Heat the PUR hot melt adhesive to a molten state, and unwind the TPU soft film layer roll with a thickness of 100 microns through traction, and use a roller doctor blade to apply the molten liquid PUR hot melt adhesive on the surface through slit extrusion. On the TPU soft film layer, control the coating thickness to 20-30 microns, and quickly cool the coated glue into a solid to obtain a transparent adhesive layer, and finally wind it into a roll material. During this process, the glue does not react, and the transparent adhesive layer The kinetic friction coefficient of the surface is less than 0.5. Then, on the surface of the soft film layer away from the transparent adhesive layer, a UV transfer layer, a PVD coating layer, and an ink cover layer are sequentially formed, and then the above-mentioned product is cut into the same size as the shell substrate, and the shell is positioned by the CCD The base material and the product obtained above are covered with an isol...

Abstract

The invention provides a shell assembly, a preparation method thereof and electronic equipment. The method comprises the steps of forming a transparent adhesive layer on one surface of a soft film layer, wherein the dynamic friction coefficient of the surface, which is away from the soft film layer, of the transparent adhesive layer is less than 1.0; attaching the transparent adhesive layer to the inner surface of a shell base material, and performing first solidification treatment on the transparent adhesive layer so as to bond the soft film layer to the shell base material through the transparent adhesive layer, wherein the drawing force of the transparent adhesive layer after the first solidification treatment is greater than or equal to 16N/inch. According to the method, the formation of folds at the positions such as corners of the shell base material can be avoided, so that the processing yield is greatly improved. In addition, the obtained shell assembly is more excellent in appearance effect and better in use experience.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and in particular, relates to a casing assembly, a preparation method thereof, and electronic equipment. Background technique [0002] At present, the solution of attaching decorative film to electronic equipment shells is generally to paste OCA optical film on the back of PET decorative film. Gorgeous looks and durable reliability. However, the technology in the related art can only realize the lamination of the decorative film on the flat or small-curved electronic device casing. When the edge of the battery cover has a large-curved surface, wrinkles are easily generated due to the excessive curvature of the four corners, resulting in poor lamination. [0003] Therefore, the related technology of pasting decorative films on electronic equipment casings still needs to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical...
