Problems solved by technology

If the substrate is broken at this time, the robot arm enters the rework machine and cannot take the piece normally, causing collision between the robot arm and the inside of the rework machine, resulting in damage to the robot arm and internal damage to the equipment
Seriously affects the production efficiency of the display panel and increases the production cost

Abstract

The invention provides a substrate breakage detecting device which comprises detecting units and an output element.The detecting units are arranged below a substrate and comprise light transmitters and light receivers matched with the light transmitters, and the output element is connected with the light receivers and is used for outputting detection results.The substrate breakage detecting device has the advantages that whether the substrate is broken or not can be detected by the aid of linear propagation principles of light, the detection results can be outputted by the output element, accordingly, breakage anomaly of the substrate can be detected, and the substrate production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of display panel processing, in particular to a substrate fragment detection device and substrate processing equipment. Background technique [0002] With the continuous development of backlight display technology, liquid crystal display devices such as liquid crystal displays (Liquid Crystal Display, LCD) have been widely used as display components in electronic products such as mobile phones, digital cameras, and personal digital assistants (Personal Digital Assistant, PDA). [0003] In the production process of liquid crystal displays, the glass used as the substrate needs to be coated, but the coating is often flawed due to abnormal interference of the process or incoming materials. Therefore, it needs to be sent to the alignment film dry rework machine by a mechanical arm to remove the coating for reprocessing. In the existing alignment film dry rework machine, after the coating is removed, the substrat...
