Liquid crystal panel carrying arm with scanning function

The liquid crystal panel carrying arm with the scanning function is provided with an arm base and two arm teeth arranged side by side in the left-right direction, the rear ends of the two arm teeth are both fixedly arranged on the arm base, and a plurality of vacuum suction cup devices are fixedly arranged at the bottoms of the arm teeth in the front-back length direction of the arm teeth. A scanning sensor capable of scanning whether a liquid crystal panel exists or not is fixedly arranged at the front end of any arm tooth, a hollow channel used for penetrating through an air channel pipeline on the vacuum suction cup device and a wire harness on the scanning sensor is formed in the arm tooth in the front-back length direction of the arm tooth, and the hollow channel penetrates through the front end and the rear end of the arm tooth. According to the liquid crystal panel carrying arm with the scanning function, the research and development cost is reduced, empty layers can be skipped, redundant actions are g
