At the same time, a telescopic mechanism 210 and a rotating mechanism 220 are arranged on each grasping component 200, so that the piston 211 on the telescopic mechanism 210 moves downward along the moving groove of the piston cylinder 213 under the positive pressure air source input by the first air delivery pipe 215, thereby driving the linkage rod 212 fixedly connected to the bottom of the piston 211 to move downward along the vertical direction, so that the adsorption plate 232 on the driving grasping mechanism 230 moves downward and abuts against the cover plates with different diameters. The second air delivery pipe 235 connected to the adsorption plate 232 on the grasping mechanism 230 outputs a negative pressure air source, so that the negative pressure air source adsorbs and grasps the capacitor cover plate abutted by the adsorption plate 232. The second air delivery pipe 235 on the telescopic mechanism 210 is closed, so that the elastic potential energy generated after the compression and recovery of the first elastic member 214, the metal spring, pushes the piston 211 upward, so that the grasping component 200 returns.

At the same time, the rotating mechanism 220 drives the grasped capacitor cover to rotate, thereby improving the grasping and welding orientation of the capacitor, and improving the grasping and processing efficiency of the capacitor cover plate grasping device;

[0037] III. By arranging a moving mechanism 100 on the capacitor cover plate grasping device, the second rotation driving member 130 on the moving mechanism 100 drives the moving plate 110 installed with two grasping components 200 to reciprocate along the length direction of the slide rail 120, so that the two grasping components 200 can grasp and place the cover plate during welding and grasp and take the cover plate, thereby improving the grasping efficiency of the cover plate grasping device and the production efficiency of the capacitor.
