[0013] 1. This type of panel visual inspection equipment uses a correction mechanism. Whenever a panel is conveyed to the bottom of the inspection cover by the conveyor belt, the cylinder drives the telescopic rod to extend and retract, driving the limit plates to clamp the two sides of the panel. The spring can relieve the force and buffer it to prevent the panel from breaking due to excessive clamping force. The position of the limit plate can be corrected under the limiting action of the limit plate, so that the panel is directly under the inspection camera. The inspection camera can fully capture the image of the panel and ensure that the panel is always placed in the center of the camera's field of view, thereby improving the accuracy and consistency of inspection.

[0014] 2. This is a panel visual inspection device. Through the setting of the pushing mechanism, if the detected panel is unqualified, the hydraulic cylinder will drive the push plate to rise and fall so that the height of the push plate is consistent with that of the panel. At the same time, the setting of the second motor and the slide will drive the hanger to move, and then push the panel to the top of the slide, so that the defective panels can be automatically picked out.
