Abstract

The present invention relates to the technical field of display, and discloses a glass substrate conveyer. The glass substrate conveyer comprises a rack, a conveying member mounted on the rack, a power system for driving the conveying member, a light sensing system mounted below the conveying member, and a controller connected with the power system. According to the present invention, the broken glass substrate can be easily found in time.

First claim

The invention claimed is:

1. A glass substrate conveyer, comprising: a rack, a conveying member mounted on said rack, a power system for driving said conveying member, as light sensing system mounted below said conveying member, and a controller connected with said power system, wherein
said conveying member comprises a conveying belt mounted on said rack and a plurality of conveying rolls which are sequentially horizontally mounted on said rack, and any two adjacent conveying rolls are mutually parallel and have a gap therebetween, thereby forming a rectangular conveying member;
said light sensing system comprises a plurality of light sensing units, the plurality of light sensing units are sequentially arranged below at least one pair of opposite sides of said conveying member and the arrangement direction thereof is parallel to the corresponding sides of said conveying member, and light rays from the light sensing units below the same pair of opposite sides are mutually parallel, for detecting glass fragments falling off a broken glass substrate; and
said controller is respectively connected with individual light sensing units to receive and process signals from the light sensing units as well as send a control signal to said power system according to a processing result, and wherein
each light sensing unit comprises two portions respectively mounted below two opposite sides of said conveying member,
said two portions being respectively a laser distance sensor and a reflective baffle, wherein
said laser distance sensor detects a distance from the nearest object, and
said controller is connected with said laser distance sensor to receive a distance signal detected by said laser distance sensor and send a control signal to the power system if the received distance signal is less than a standard distance signal, said standard distance signal indicating a distance, which is detected by said laser distance sensor, from the reflective baffle.

2. The glass substrate conveyer according to claim 1 , wherein light rays from said light sensing units are parallel to axial directions of said conveying rolls or light rays from said light sensing units are perpendicular to axial directions of said conveying rolls.

3. The glass substrate conveyer according to claim 1 , wherein said two portions are respectively a light transmitter and a light receiver, and said controller is connected with the light receiver, wherein
said light receiver receives a light signal transmitted by said light transmitter, and transfers the light signal to said controller, and
said controller sends a control signal to the power system when detected that the light signal received by any receiver is interrupted.

4. The glass substrate conveyer according to claim 1 , wherein the light sensing units below the same pair of opposite sides are arranged equidistantly.

5. The glass substrate conveyer according to claim 1 , wherein a fragment collector is arranged below said conveying member.

6. The glass substrate conveyer according to claim 1 , further comprising a display, which is connected with said controller, for displaying signals detected by said light sensing units.

7. The glass substrate conveyer according to claim 1 , further comprising an alarm apparatus, which is connected with said controller, for sending out an alarm.
