Polishing system and polishing method

Abstract

The invention discloses a polishing system and a polishing method. The polishing system comprises a polishing fixing device and polishing equipment, and can polish to-be-polished sheet-like products which are stacked together, and positioning holes used for positioning are formed in each to-be-polished product. The invention aims to provide the polishing system and the polishing method. After hundreds of products are fixed by the polishing fixing device of the polishing system, hundreds of products can be polished at a time by the polishing equipment, the rejection rate of the polished products is substantially reduced while polishing efficiency is increased, and the rejection rate is as low as about 0.3%.

Description

technical field [0001] The invention relates to the field of polishing, in particular to a polishing system and a polishing method. Background technique [0002] The production process of the light guide plate: the substrate (usually optical grade acrylic or PC sheet) is cut into a fixed size, and then the cut substrate is polished to a precise size, and finally on the bottom surface of the substrate Use laser engraving, V-shaped cross grid engraving, UV screen printing and other technologies to print the light guide dot structure. [0003] The traditional polishing technology is to directly stack the base materials of the light guide plate to be polished, and fix them with a baffle for processing. Because the base material of the light guide plate is provided with a boss with a height of about 1 mm, such as image 3 As shown, the base material of the stacked light guide plate is easy to tilt, so that only a small amount of products can be processed each time, and due to the...

Problems solved by technology

[0003] The traditional polishing technology is to directly stack the base materials of the light guide plate to be polished, and fix them with a baffle for processing. Because the base material of the light guide plate is provided with a boss with a height of about 1 mm, such as image 3 As shown, the base material of the stacked light guide plate is easy to tilt, so that only a small amount of products can be processed each time, and due to the relatively high requirements for the length and width of the polished products, the product rejection rate is relatively high

At present, 10 pieces of light guide plate substrates are generally stacked and then polished, the scrap rate is 40%-50%, the polishing efficiency is low, and the scrap rate is high, which cannot meet the production needs
