Processing technology of glass cover plate with medium and large size

Abstract

The invention discloses a processing technology of a glass cover plate with a medium and large size. The method comprises the following steps: step 1, glass cutting: cutting a raw material to be processed by using a glass cutting machine until the allowance of the overall dimension is about 1mm away from a finished product; step 2, profiling by a fine carving machine: pasting a layer of special composite material on the tool surface in contact with the glass cover plate, placing the glass cover plate on the surface of the special composite material, fixing the glass cover plate through vacuum adsorption, and processing the glass to a size required by a finished product by using a forming grinding head; step 3, sheet placement: the processed glass cover plate is flatly placed in the turnover box with the high-density sponge laid, another piece of sponge is used for covering, and one piece of glass is allowed to be placed between every two pieces of sponge; and 4, cleaning the flat plate: cleaning the glass cover plate by using a glass flat plate cleaning machine. The method is simple to operate, accurate in time, low in processing cost and high in rate of finished products, and reduces environmental pollution, personnel requirements and skill requirements.

Description

technical field [0001] The invention belongs to the technical field of glass cover plate processing, and in particular relates to a process for processing medium and large-sized glass cover plates. Background technique [0002] In the existing traditional glass cover processing technology, it usually needs to go through a series of steps such as spraying protective oil, cutting, CNC, inserting the basket, removing the protective oil, ultrasonic cleaning, inserting the basket, chemical toughening, inserting the frame, and ultrasonic cleaning. There are the following defects: 1. When spraying protective oil, personnel need to wear dust masks all the way, which pollutes the surrounding environment and needs to be filtered and exhausted; 2. The product processing process needs to go through multiple frame insertions, especially for medium and large sizes. The glass cover plate requires extremely high skills for employees. Improper operation of taking the film and inserting it in...

AI Technical Summary

Problems solved by technology

There are the following defects: 1. When spraying protective oil, personnel need to wear dust masks all the way, which pollutes the surrounding environment and needs to be filtered and exhausted; 2. The product processing process needs to go through multiple frame insertions, especially for medium and large sizes. The glass cover plate requires extremely high skills for employees, and improper operation of taking the film and inserting the basket can easily cause defective products and increase product scrap rate; 3. After the glass cover plate sprayed with protective oil is processed, the protective oil must be removed

The protective oil for fading uses strong alkali, which has potential safety hazards and is highly corrosive to glass, which can easily cause bluish defects in glass made of sodium calcium; 4. Spraying protective oil and protective oil for fading increases the demand for personnel and material costs

5. The product uses ultrasonic cleaning, which requires more cost input for manpower and cleaning frames. The current glass cover processing technology has high personnel requirements and high processing costs.
