As labor costs are getting higher and higher, the development of science and technology has gradually replaced manual labor with automated equipment. In the TP coating industry, automated CV transmission robots have gradually replaced manual film picking, which has the advantages of low cost and reduced risk of human error. In the prior art, the principle of conveying and loading the coated substrate (substrate product) is as follows: the robot is located above the substrate, the conveying guide wheel is located below the substrate, the robot grasps the non-film surface of the substrate with a vacuum suction cup for loading, the product is placed on the substrate rack for vacuum coating, and a coated substrate is formed.

After adjustment, the substrate is placed horizontally on the two conveyor belts 105 with the coated surface facing up, and the drive motor 104 is started to drive the rotating rod 102 to rotate. The convex 1021 and the concave 1031 are limited and matched to drive the conveying guide wheel 103 to rotate, thereby driving the conveyor belt 105 to convey the substrate. The contact area with the substrate during transmission is reduced to reduce the chance of scratching. When taking the substrate, the electric push rod 205 pushes the robot body 206 upward, and the vacuum suction cup 207 is turned on to suck the bottom end of the substrate. Next, the servo motor 204 is started to drive the robot body 206 to rotate, and the substrate is driven to rotate 90 degrees to separate it from the conveyor belt 105, and the film taking is completed.
