Graded storage method of substrates

Abstract

The invention provides a graded storage method of substrates. A random storage mode and a mixed storage mode are additionally arranged on the basis of a manual specific storage mode. When graded storage of the substrates is performed, the substrates of large number and grade of multiple substrates are arranged in corresponding manual specific storage mode carriers so that the loading rate of the carriers can be guaranteed, and the efficiency of the corresponding grades of substrates to the next station can be enhanced; partial grades of substrates are randomly arranged in random storage mode carriers so that empty waste of the carriers caused by the fact that an operator forgets to set the grade can be prevented, and an elastic space for storing multiple grades of substrates can also be provided for machines having less storage positions; and multiple grades of substrates of less number are arranged in mixed storage mode carriers in a mixed way so that each carrier is enabled to be fully loaded as much as possible, the utilization rate of the carriers can be enhanced, the transport time can be reduced, the efficiency of later continuous classification and waiting can be enhanced and the capacity of the production line can be greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of display panel manufacturing, in particular to a hierarchical storage method for substrates. Background technique [0002] With the development of display technology, display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) display have the advantages of high image quality, power saving, thin body and wide application range. , and are widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and become the mainstream of display devices. [0003] The liquid crystal display currently on the market generally includes a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many small vertical and horizontal wires bet...

AI Technical Summary

Problems solved by technology

At present, the commonly used hierarchical storage method for substrates is to manually set each carrier to store a specific grade of substrates before placing multiple carriers in the storage position. This method is logically simple and easy to operate. As the number of substrates increases, there will be a large number of substrates in some grades, and the corresponding carriers are not enough to store, while the number of substrates in other grades is small, and there are more vacant positions in the corresponding carriers, and the full load rate of the carriers is low. ;At the same time, because the storage position of the production line is certain, when the number of substrate levels is too large, the carriers on the storage position will not be enough to store all levels of substrates
