The utility model relates to a kind of mechanical hand with automatic deviation rectification function.The mechanical hand includes
machine hand support,
machine hand main body, mechanical hand calibration mechanism;
Machine hand support includes support base, and each one support side frame of two sides of support base is arranged side by side;
Machine hand main body includes the transverse
linear drive element being equipped at the top of two support side frames, longitudinal
linear drive element being equipped on transverse
linear drive element, lifting linear drive element being equipped on longitudinal linear drive element, pick-and-place structure being equipped on lifting linear drive element;Mechanical hand calibration mechanism includes the camera vision calibration structure being equipped on support base, the vision calibration mark structure being equipped on the bottom of pick-and-place structure, and corresponding with camera vision calibration structure upper and lower cooperation.The utility model can solve the problem that traditional mechanical hand is prone to point deviation after long time cycle action, and then affect feeding accuracy, cause a large number of alarm, affect production efficiency.
