A detection device, color film repair equipment and detection method

Abstract

The invention provides a detection apparatus, a color film repairing device and a detection method. The detection apparatus comprises a bearing table, a positioning clamp, an adsorption unit, a driving unit and a control unit, wherein the positioning clamp is used for clamping a product to be detected so as to perform positioning on the product to be detected; the adsorption unit is used for adsorbing and fixing the product to be detected to the bearing table; the driving unit is used for driving the positioning clamp to perform lifting movement in a vertical direction perpendicular to a bearing surface of the bearing table, and driving the positioning clamp to horizontally move to a first positioning position and a second positioning position in a horizontal direction parallel to the bearing surface of the bearing table; and the control unit is connected to the driving unit and used for controlling the working state of the driving unit, so that the driving unit drives the positioningclamp to locate at the first positioning position or the second positioning position, so that the product to be detected can be subjected to secondary positioning in the horizontal direction. According to the detection apparatus, the color film repairing device and the detection method, a problem that the color film repairing device in the prior art has a repairing blind area can be solved, and the yield of products to be detected can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a detection device, color film repair equipment and a detection method. Background technique [0002] In the production process of the color film substrate of the liquid crystal display panel, BM (black matrix), R (red color film), G (green color film), B (blue color film), OC (flat layer), PS (isolation layer) need to be carried out in sequence. Matter pad) process, each process will inevitably produce microscopic defects in the production process, and the defects will reduce the product yield. Therefore, using color film repair equipment to repair microscopic defects after each process can greatly improve product yield. . [0003] The repair methods of the existing color film repair equipment are: after the BM process is completed, perform Auto Laser repair (repair under the transmitted light source), after the R, G, B, and OC processes are completed, perform Auto Tape repair...
