Cassette

Abstract

The invention discloses a gate. The gate comprises a shell, multiple bearing layers arranged in the shell, and multiple positioning devices; the shell has an opening; each bearing layer surrounds the inner wall of the shell to bear a basal plate; and the multiple positioning devices are arranged in the opening corresponding to the bearing layers for fixing the basal plate. Compared with the prior art, the gate can achieve an aligning effect on the basal plate through setting the positioning devices, and achieves a fixing effect on the basal plate in the carrying process to prevent crushing caused by displacement or throwing of the basal plate.

Description

technical field [0001] The invention relates to a substrate storage device, in particular to a cassette. Background technique [0002] In the display manufacturing process, due to the complex production process and numerous steps, the glass substrate needs to go back and forth between relatively independent production equipment many times. In actual production, a cassette capable of carrying multiple glass substrates is generally used as a carrying device for storing and transporting glass substrates, and the cassette is placed on a mechanical handling device to go back and forth between various production equipment. The manipulators of each production equipment take out a single glass substrate from the cassette to carry out the production process, and return the glass substrate to the cassette after the production process is completed, and so on until the entire production process is completed.

Problems solved by technology

[0004] However, sometimes it is necessary to transfer the entire cassette with the glass substrate 4. When the thimble is not firmly fixed, or there is moisture on the surface of the glass substrate 4, the transfer process (such as figure 1 (indicated by the arc arrow in the middle) will cause the glass substrate 4 to shift or be thrown out, which may cause the glass substrate 4 to break when the subsequent process is carried out after the transfer
