Abstract

The invention provides a base plate conveying device which comprises a conveying belt used for carrying a base plate and at least two magnetic levitation driving wheels, wherein the conveying belt is arranged on the at least two magnetic levitation driving wheels; a plurality of first magnetic blocks are arranged on each of the magnetic levitation driving wheels at intervals along circumferential direction; a plurality of second magnetic blocks opposite to the first magnetic blocks are distributed on the conveying belt at intervals; the opposite surfaces of the first magnetic blocks and the second magnetic blocks are homopolar and are used for generating a magnetic levitation force between the second magnetic blocks and the first magnetic blocks for driving the conveying belt to move between the at least two magnetic levitation driving wheels during a rotating process of the magnetic levitation driving wheels. The base plate conveying device provided by the invention is capable of reducing base plate scratching; no friction particle is generated; the influence on product quality caused by production line dust generation is prevented.

Description

technical field [0001] The invention relates to the technical field of liquid crystal manufacturing, in particular to a substrate conveying device. Background technique [0002] At present, in the liquid crystal panel manufacturing industry, the conveyor belt of the substrate conveying device used to convey the glass substrate is generally formed by arranging many rollers. Such as figure 1 As shown, the glass substrate 30 advances under the driving of the rollers 10a, and enters the rear group of rollers from the front group of rollers. [0003] Traditional substrate conveying devices have the following problems: [0004] 1. The glass substrate 30 rotates relative to the roller 10a, which is prone to defects such as scratches; [0005] 2. If figure 2 As shown, this kind of substrate conveying device is mostly one-way conveying, and it is installed between two adjacent process equipments, occupying a large area of ​​space; [0006] 3. The roller is driven by the roller,...
