Problems solved by technology

In the prior art, it is not possible to detect whether the glass substrate is damaged during the process of temporarily storing the glass substrate in the cassette until the cassette for storing the glass substrate is moved to the display panel process line through the automatic storage system. Therefore, the damaged glass substrate in the above process may not be found until the proces

Example Embodiment

[0013] Refer to Figure 1 to Figure 3 , The glass substrate detection device of the embodiment of the present invention is used to detect whether the glass substrate 40 temporarily carried in the cassette 50 is damaged. The detection device can detect part or all of the glass substrates 40 in the same cassette 50 at one time.

[0014] The cassette 50 is used to carry multiple glass substrates 40 at a time. The cassette 50 includes a plurality of supporting surfaces (not shown) arranged parallel to each other in a vertical direction, and each supporting surface is used to carry a glass substrate 40. After the glass substrate 40 is installed in the cassette 50, the adjacent glass substrates 40 are separated by a certain distance. In practical applications, in order to increase the number of glass substrates 40 in the cassette 50, the distance between adjacent glass substrates 40 is small. Therefore, when the cassette 50 is filled with glass substrates 40, except for the glass sub...

Abstract

The invention provides a detection device and a detection method for a glass substrate, and is used for detecting whether the glass substrate bore in a clamping case is damaged or not. The detection device comprises at least one sensor group and at least one processing unit, wherein the sensor group comprises an illuminating element on one side of the glass substrate and two illuminated elements respectively positioned on the two sides of the glass substrate, and the processing unit is used for judging whether the luminance difference of the luminance of the two illuminated elements is in the preset scope or not; and if the luminance difference is not in the preset scope, the glass substrate to be detected is broken. Through the detection method provided by the invention, the phenomenon that the broken glass substrate enters into a display panel processing line can be reduced or avoided.

Description

technical field [0001] The invention relates to the detection field, in particular to a detection device and a detection method for a glass substrate. Background technique [0002] Glass substrates used for display panels such as computer monitors and televisions are temporarily stored in cassettes before entering the production line. The cassette is usually provided with a plurality of support surfaces in the vertical direction, and each support surface is used to support a glass substrate. Therefore, there is a certain distance between two adjacent glass substrates installed in the same cassette. Before the display panel is produced, the cassette containing multiple glass substrates is moved to the display panel process line by a mechanical automatic device. [0003] Since the distance between two glass substrates placed on adjacent supporting surfaces in the same cassette is small, it is not easy to find whether the glass substrates are cracked / damaged during storage and...
