Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a loading and unloading manipulator. Background Art

[0002] Traditional workpiece loading is highly repetitive and lacks technical skills. For this reason, many factories have changed the loading method to a robot arm, but the adaptability of the robot arm is poor. When the size of the workpiece changes, the robot arm needs to be adjusted to adapt to the size of the workpiece. However, the surface of the workpiece is relatively smooth. If the workpiece is clamped vertically, if the clamping force is not enough, it is easy to cause the workpiece to slip, and if the clamping force is too large, it is easy to cause the workpiece to deform and damage.
