Generally speaking, in order to reduce cost, it is easy to find ways of increasing the size of the glass substrate, reducing the number of masks, increasing the yield of the base station and the yield of the product, and purchasing raw materials nearby, etc. by looking at the development process of the LCD, it is the direction of continuous efforts of many LCD production enterprises. Glass substrates are important raw materials for producing TFT-LCDs, with a cost of about 15-18% of the total LCD cost, and a short twenty-year period has elapsed from the first generation (300mm × 400mm) to the present tenth generation (2,850mm × 3,050 mm). However, because the requirements of the glass substrate for the LCD on chemical composition, performance and production process conditions are extremely high, and in order to break through monopoly, the local matching of the upstream raw materials of the production enterprise and the substantial reduction of the manufacturing cost are also the necessary ways for the development of the industry.
Therefore, the LCD plane target material is used as an upstream product of the liquid crystal display and has the characteristics of larger size and fragile material. Therefore, how to improve the efficiency on the premise of ensuring the product quality becomes a difficult point.

The automatic feeding device can effectively solve the problems by matching an automatic assembly line with an automatic feeding module and using the support arm of the feeding module to support the product to be sent to a feeding trolley, so that the target polishing turnover rate, the labor efficiency and the personnel product safety rate are improved.
