[0024] 1. When the utility model is used, the external robot drives the first octagonal tube and the second octagonal tube to move in the direction close to the product through the pancake shaft, the flange connecting plate and the gripper base. When the positioning component detects the position of the product, the vacuum adsorption component adsorbs the product on the vacuum adsorption component, and at the same time the self-locking pneumatic clamping component clamps and fixes the product and self-locks it, and still provides clamping force when the air is cut off. The risk of product falling is reduced by the cooperation of the vacuum adsorption component and the self-locking pneumatic clamping component. The use safety is high. The position detection component can monitor the position of the product during the clamping process.

At this time, the first strong clamping cylinder and the second strong clamping cylinder stop running. Since the first strong clamping cylinder and the second strong clamping cylinder are both equipped with a self-locking structure, they can still provide clamping force even when the air is cut off, so there is no risk of the product falling, and the safety of use is high.

[0026] 3. When the positioning assembly of the utility model detects the position of the product, the vacuum suction cup is driven to the top of the product by the first suction cup fixing plate, the second suction cup fixing plate, the second octagonal tube and the first octagonal tube, and continues to move in the direction close to the product. When the vacuum suction cup contacts the product, it adsorbs the product. Then the first strong clamping cylinder and the second strong clamping cylinder clamp and fix the front, back, left and right of the product through the clamping block. The product is further clamped by the cooperation of the vacuum suction cup and the clamping block, thereby reducing the risk of the product falling.

[0027] 4. The external robot of the utility model drives the first octagonal tube and the second octagonal tube to move toward the product through the pancake shaft, the flange connecting plate, and the gripper base, and then moves toward the product through the third octagonal tube, the fourth octagonal tube, the third octagonal tube mounting seat, the cylinder connecting plate, the locating pin cylinder and the locating pin.
