[0002] With the rapid development of robot technology, industrial robots have been widely used in various fields. With the popularization of robots, the demand for industrial robot end effectors is also increasing. However, the existing robots and their grippers are not flexible enough and are subject to many restrictions. Since the clamping force of the clamp is small or the operation is inconvenient and not flexible, the size of the object to be grasped is greatly restricted. Therefore, a clamp gripper with a simple structure and greater clamping force is needed.

[0003] The prior art also has the following defects during use:

[0004] The robots and their grippers in the prior art have low flexibility and are subject to various restrictions. Due to the low clamping force or inconvenient operation of the clamp, they do not have high flexibility, resulting in the size of the grasped object being highly restricted. For workpieces that are relatively heavy and complex in shape, most of the current robot clamps cannot meet the grasping requirements and the workpiece is prone to falling.

[0005] In view of this, we propose a robot multi-gripper device to solve the existing problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model classifies different workpieces according to their shapes and sizes to manufacture a certain number of grippers of different specifications. Different grippers can be switched to pick up materials through automatic disc changing.
