AI Technical Summary

Technical Problem

In existing technologies, glass, plastic and other products are often damaged or scratched on worktables due to factors such as foreign matter residue, uneven material, and processing debris, which affects product yield, production costs and optical performance.

Method used

The system employs a gradient groove structure made of double-layer fluoropolymer material and a laser etching fixture system. By using grooving fixtures and hole-opening fixtures, clearance grooves and suction holes are formed on the worktable. Combined with a vacuum adsorption system, it achieves zero contact with foreign objects and self-chip removal.

Benefits of technology

It effectively prevents foreign object pressure and scratches, improves processing quality, reduces the scratch rate by nearly 100%, extends the life of the protective layer, improves processing accuracy and efficiency, and reduces operation difficulty and cost.

Abstract

The invention relates to the technical field of product processing assistance, in particular to a method and equipment for preventing a working table from being crushed and scratched by foreign matters, which are used for preventing glass, plastic, acrylic and other products from being crushed or scratched due to residual foreign matters when the products are processed on the working table, and are suitable for machining, product assembling and other scenes with high precision requirements. A method for preventing a working table from being crushed and scratched by foreign matter is characterized by comprising the following steps that S1, the working table is cleaned; s2, pasting a first protective layer on the cleaned table top; s3, positioning is conducted through a grooving jig, and an avoiding groove is formed in the first protection layer in a cutting mode; s4, a second protective layer is pasted to the first protective layer area, the stretch rate of the second protective layer is controlled to be 3%-5%, and a gradient inclined groove is formed between the two protective layers; and S5, positioning is conducted through a trepanning jig, and air suction holes are formed in the grooved first protection layer area.
