The two ends of the supporting fork arm 3 are equipped with a picking module 4, and the set 3D industrial camera 46 can capture the three-dimensional shape, position and posture of the object, and can quickly and accurately identify the status of disordered incoming materials and implement gripping. At the same time, the picking module 4 adopts a spacing-adjustable design, so that the module can clamp crankshafts of different lengths and specifications, thereby improving the scope of use of the mechanism.

[0024] In this embodiment, the gas-electric slip ring 5 is a device that combines the functions of an electric slip ring and a gas slip ring. It can simultaneously transmit electricity, signals, and gas media between a rotating body and a stationary body. This device is particularly suitable for complex rotating equipment that requires both electrical connection and gas transmission.

With the cooperation of the hollow rotary table 2 and the supporting fork arm 3, the rotation angle is adjusted according to the processing system to realize the synchronous operation of loading and unloading. Compared with single-station gripping, the double-station can complete more product processing in a short time, reducing production costs; the set 3D industrial camera 46 can capture the three-dimensional shape, position and posture of the object, and can quickly and accurately identify the status of disordered incoming materials and implement gripping.
