Processing technology of multilayer material composite waterproof and dustproof net

Abstract

The invention provides a processing technology of a multilayer material composite waterproof and dustproof net. The processing technology comprises the following steps: cutting a parting line along the middle of a double faced adhesive tape and cutting a positioning hole in the double faced adhesive tape; punching holes in the double-faced adhesive tape, and compounding a silk screen on the adhesive surface of the lower double-faced adhesive tape; manually adhering the upper double-sided adhesive tape to the silk screen, and detecting by using CCD equipment; cutting off the double-sided adhesive tape and the silk screen at the handle position, compounding a PET release film on the adhesive surface of the upper double-sided adhesive tape, and overturning the material belt; cutting out two sides, adjacent to the handle position, in the appearance of the product in a jump cutting mode; and cutting out one side, opposite to the handle position, of the product appearance in a jump cutting mode, and cutting out the handle appearance. The product appearance is cut by detaching a cutter, so that no displacement and no sheet falling are ensured; the jump cutting mode avoids the situation that the edge of the product is impressed in the machining process; and the handle is cut by turning over the material belt, so that the phenomena of reverse release and layering of the product are effectively solved, the precision of the produced product is high, and the production yield and efficiency are improved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic products, in particular to a processing technology of a composite waterproof and dustproof net made of multilayer materials. Background technique [0002] With the rapid development of science and technology and the continuous progress of society, people's living standards are improving day by day, and electronic products such as mobile phones, tablet computers, and LCD TVs are becoming more and more popular. These electronic products have become an important part of people's life and work. Due to its excellent waterproof, dustproof, sound permeability, filtering and other properties, as well as good temperature resistance, thermal stability and chemical stability, silk mesh is widely used in electronic products such as mobile phones, tablet computers, and LCD TVs. [0003] At present, the processing of waterproof and dustproof net generally adopts the following process: use a circular...

AI Technical Summary

Problems solved by technology

[0004] Since waterproof and dustproof net products are generally relatively small, waste is discharged after directly cutting the shape of the product, the product is easy to fall off and shift, and the screen is also prone to threading; if the shape of the product is directly cut, the handle of the product will have knife marks. After the product is assembled, it is easy to cause the product to be reversed; therefore, the yield rate of the product produced by this process is low, and it is not suitable for mass production
