a transmission device

Abstract

The invention provides a conveying device. The conveying device comprises a conveying body support, a supporting unit used for supporting a to-be-conveyed object and conveying units. The supporting unit comprises a plurality of supporting rods used for being supported on the two opposite sides of the to-be-conveyed object. The conveying units are arranged on the conveying body support and connected with the supporting unit and can move on the conveying body support to drive the supporting unit to move so that the to-be-conveyed object can be conveyed. The conveying units are arranged on the two sides of the conveying body support and are used for supporting and conveying the to-be-conveyed object. Compared with the prior art, contact between the to-be-conveyed object and the conveying device in the conveying process is reduced, the breakage rate in the carrying process is reduced, and the production yield is increased. When to-be-conveyed objects with patterns on the back side are encountered, the locality and possibility of scratching of the back side patterns can be greatly reduced, the quality is guaranteed, and the conveying speed is more easily controlled. Compared with a traditional conveying device, the number of wheels is reduced, and the equipment purchasing and installing and maintaining cost is saved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a transmission device. Background technique [0002] In the prior art, the conveying device generally adopts the way of roller conveying. Taking the TFT-LCD (Thin Film Transistor-Liquid Crystal Display) manufacturing field as an example, the glass substrate is passed from one process to another through a substrate conveying device. During the conveying process, the glass substrate is carried on the rollers. Through the rotation of the rollers, the glass substrate and the rollers generate relative motion, which drives the glass substrate to move along the horizontal plane. However, in the substrate transfer device in the prior art, the rollers are inevitably in contact with the glass substrate in a large area during the transfer process of the substrate, and the glass substrate is easily damaged during the transfer process, resulting in poor production; The speed is not easy...

Problems solved by technology

However, in the substrate transfer device in the prior art, the rollers are inevitably in contact with the glass substrate in a large area during the transfer process of the substrate, and the glass substrate is easily damaged during the transfer process, resulting in poor production; The speed is not easy to control; in addition, the number of rollers is too large, which increases the cost of factory equipment procurement and maintenance costs, etc., and large-scale contact, especially for glass substrates with back patterns, the regional and possibility of scratches are high. certain risk
