Cassette carrying device, liquid crystal panel production system and cassette conveying method

Abstract

The invention relates to the field of manufacturing of liquid crystal panels, and discloses a cassette carrying device, a liquid crystal panel production system and a cassette carrying method of the liquid crystal panel production system. The cassette carrying device comprises a conveying device (3) which comprises a loading port for loading a cassette, an unloading port for unloading the cassette, a supply port for supplying glass to process equipment and a receiving port for receiving the glass output by the process equipment and can be used for moving the cassette between the supply port and the receiving port, a power unit which is used for driving the conveying device to operate so as to move the cassette placed on the conveying device, and a control unit which can control the conveying device according to the state of the cassette placed on the conveying device. The cassette carrying device provided by the invention can reduce damage to the glass in a carrying process, relieve the load on a storehouse and effectively improve the production efficiency.

Description

technical field [0001] The invention relates to the field of liquid crystal panel manufacturing, in particular to a cassette carrying device, a liquid crystal panel production system and a cassette transport method thereof. Background technique [0002] With the continuous development of the liquid crystal display technology, the application of the liquid crystal display is more and more extensive, and the liquid crystal panel is an important part of the liquid crystal display. [0003] In the liquid crystal panel manufacturing industry, glass substrates are usually stored in cassettes, which are stored in storage equipment. During the production process, the actual cassettes loaded with glass substrates and the ones without glass substrates are separated by mechanical arms and other equipment. The empty cassettes are transported from the storage equipment to the substrate supply device and the substrate receiving device of the liquid crystal panel manufacturing equipment re...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned substrate supply device and substrate receiving device need to be provided with elevating mechanism, positioning mechanism, etc. on each supply unit and receiving unit respectively, and because it is impossible to make both supply units of the substrate supply device aligned with the glass inlet end of the liquid crystal panel manufacturing equipment Therefore, it is necessary to set up lateral transfer equipment to transfer the glass substrate at the supply unit that cannot be aligned with the glass inlet end of the liquid crystal panel manufacturing equipment to the glass inlet end. Similarly, the substrate receiving device also needs to be equipped with lateral transfer equipment, resulting in its Complex structure, large space occupation and high cost

In addition, in the manufacture of glass panels, it is necessary to transport the cassettes multiple times (the production of a cassette product needs to transport the cassettes 4 times), the workload is heavy, and the glass substrate or glass panel is easily damaged during the cassette transport process.
