Cache device for glass substrate production line and control method thereof

Abstract

The invention relates to a cache device for a glass substrate production line and a control method thereof, solving the problems of large occupation of a conveyor belt and high production cost. The technical scheme is as follows: the control method is realized by using a horizontal conveyor belt between a preceding procedure and a post procedure and a control unit with a CPU (Central Processing unit) and a mating software program in the process of continuously delivering a glass substrate; a group of convey roll-type intermediate conveyor belts and a cache device consisting of a servo motor, an inversion mechanism and a storage mechanism for temporarily storing the glass substrate are additionally arranged between the horizontal conveyor belts in the preceding procedure and the post procedure; in the preceding procedure, the glass substrate is conveyed to the intermediate conveyor belt through the horizontal conveyor belt; based on the working state of the preceding procedure and the post procedure, a management circuit controls the cache device to perform cache processing on the glass substrate. The invention has the advantages that the length of the horizontal conveyor belt is shortened and the production space is saved by adding the cache device for storing the glass substrate on the horizontal conveyor belt in the vertical direction.

Description

technical field [0001] The invention relates to a buffer device used in a glass substrate production line and a control method thereof, belonging to the field of TFT-LCD glass manufacturing, in particular to a buffer device which saves space and effectively ensures smooth production and a control method thereof. Background technique [0002] In the manufacture of TFT-LCD glass, especially in the transmission process after glass cutting, if the production beats of the front and rear processes cannot be completely matched, or due to the shutdown of the production machinery in the subsequent process, the glass substrate will often be stuck on the conveyor belt. Then affect the normal production of the previous process. In order to reduce such effects, buffer conveyors must be set up. However, if the buffer conveyor belt is too long, it will increase the manufacturing cost, extend the total length of the production line, and affect the layout design of the entire factory. For ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that the cut glass substrate stays on the horizontal conveyor belt, which affects the production efficiency of the previous process, and designs a buffer device and its control method used in the glass substrate production line. A vertical buffer device is added between the horizontal conveyor belts, which solves the problem of large space and high cost of the conveyor belt, ensures the smoothness of the entire production line, and improves production efficiency
