[0031] Working principle:

[0032] Embodiment 1

[0033] The whole device can be used in combination with an existing robotic arm. Then, when the workpiece needs to be picked up and placed, the existing robotic arm moves and adjusts the whole device until the magnetic adsorption surfaces of the magnetic adsorption components 3 arranged on the two material taking support rods 2 are all attached to the surface of the workpiece. At the same time, the buffer pads in the clamping blocks 44 on the fixed clamping plate 43 will also be attached to the surface of the corresponding edge of the workpiece. Then, first start the electromagnetic chuck inside the magnetic adsorption component 3, and the electromagnetic chuck makes a preliminary magnetic adsorption connection to the workpiece. Then, compress air is input into the air cylinder 45, so that the output end of the air cylinder 45 drives the straight tooth plate 46 to meshingly drive the transmission gear 47. Then, the transmission gear 47 drives the moving clamping plate 42 and the clamping blocks 44 connected to the moving clamping plate 42 to rotate synchronously through the bearing. The two clamping blocks 44 move relatively, and then automatically clamp and limit the corresponding edge of the workpiece. After completion, the existing robotic arm drives the whole device and the limited workpiece to move to the designated position.

[0034] Embodiment 2

[0035] For the picking up and placing of the workpiece, operate according to the above Embodiment 1. When the material taking support rod 2 or the magnetic adsorption component 3 or the pneumatic clamping component 4 associated with the material taking support rod 2 is damaged and needs to be repaired, turn the U-shaped movable frame 52, so that the U-shaped movable frame 52 drives the two positioning hook plates 53 to rotate and adjust until the two positioning hook plates 53 and the two positioning shafts 62 are all in a separated state. Then, the material taking main rod 1 and the material taking support rod 2 can be separated for targeted repair.
