The device is compact in structure, wide in application range, and capable of achieving the state that a laser machining head swings at will at a fixed point.

Description

technical field [0001] The invention relates to a laser microhole processing device, in particular to a robot wrist for laser precision processing. Background technique [0002] The wrist of the robot is the part that connects the arm and the end effector. Its main function is to realize the three position coordinates of the end effector in the work space by the wrist after the arm and the base realize the three position coordinates of the end effector in the work space. Attitude coordinates, that is, realize three rotational degrees of freedom, and connect and support the end effector through a mechanical interface. [0003] At this stage, most of the research on robotic hands is concentrated in the research fields of multi-degree-of-freedom, flexibility, and precise positioning, but it violates the most basic requirements of real production: 1. Simple operation, 2. Simplified mechanism , 3. Low cost, 4. Clear working principle, 5 Wide applicability, etc.; making a large n...

[0003] At this stage, most of the research on robotic hands is concentrated in the research fields of multi-degree-of-freedom, flexibility, and precise positioning, but it violates the most basic requirements of real production: 1. Simple operation, 2. Simplified mechanism , 3. Low cost, 4. Clear working principle, 5 Wide applicability, etc.; making a large number of robotic hands have strong applicability in specific fields, and almost every robotic hand is aimed at a specific group of people, which greatly reduces production efficiency
