Abstract
The invention discloses a base plate edge inspection machine and an edge inspection method. The base plate edge inspection machine comprises a machine seat, wherein a moving part, a rotating prat, a scanning module and an installing part are arranged on the machine seat; the moving part is used for moving a base plate along a first direction; the rotating prat is arranged on the moving part and isused for rotating the base plate, so that the long edge direction and the short edge direction of the base plate rotate to the first direction respectively; the scanning module is used for scanning the upper edge and the lower edge of two parallel edges of the base plate in a moving state; the installing part is fixed on the machine seat; the scanning module is arranged on the installing part; when the long edge of the base plate moves along the first direction, the scanning module is used for scanning the upper edge and the lower edge of the two long edges; when the short edge of the base plate moves along the first direction, the scanning module is used for scanning the upper edge and the lower edge of two short edges. The long edges and the short edges of the base plate are switched tothe moving direction by the rotating part; the position of the scanning module is regulated, so that the distance difference of the long and short edges is overcome; the upper and lower edge detection on the four edges of the base plate can be simultaneously performed; the detection efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of substrate inspection, in particular to a substrate edge inspection machine and an edge inspection method. Background technique [0002] The preparation of the display panel needs to go through multiple processes, the process of the process of multiple processes and the process of transportation and transmission between the processes. Generally, the display panel is made of a substrate or a flexible substrate of other materials. During the above process, the edge of the substrate may occur. Defects such as breakage, splinters or contamination, which can have a significant impact on flat panel display quality, require inspection at the edge of the substrate for defects. [0003] Existing substrate edge inspection devices can only inspect the upper or lower sides of the parallel sides of the substrate, but cannot simultaneously inspect the four sides up and down, and the detection efficiency is low. [0004...
