Introduction of manipulator
In many jobs, there are many dangerous, fast, efficient and complex jobs. These things can be done by the manipulator for us. Let's take a look at the structural form of the manipulator.
At present, manipulator is the most widely used automatic mechanical device in the field of robot technology. It can be seen in the fields of industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and accurately locate a point in three-dimensional (or two-dimensional) space for operation.
Sometimes it is not necessary for the manipulator arm to have a complete six degrees of freedom, but only one or several degrees of freedom. The rectangular coordinate system manipulator can be composed of a single axis manipulator. As a component, single axis manipulator is widely used in industry. Single axis manipulator. The modularization of single axis manipulator arm greatly reduces the cost of industrial design. Because professional manufacturers have the advantages of good quality assurance and mass production, using components has more advantages than self-designed manipulator. Common orthogonal manipulator combinations include cantilever type, gantry type, vertical type, horizontal type and so on.
For semiconductor manufacturing applications, the commonly used manipulator is used to transport wafers. According to different structural forms, the manipulator is divided into multi joint manipulator, rectangular coordinate manipulator, spherical coordinate manipulator, polar coordinate manipulator, cylindrical coordinate manipulator, etc. 6-DOF manipulator. It consists of six degrees of freedom: X movement, y movement, Z movement, X rotation, y rotation and Z rotation. Horizontal multi joint manipulator generally has three main degrees of freedom, Z1 rotation, Z2 rotation and Z movement. By adding x rotation to the execution terminal, y rotation can reach any coordinate point in space. The manipulator in rectangular coordinate system has three principal degrees of freedom. It is composed of X movement, y movement and Z movement. By adding x rotation, y rotation and Z rotation to the execution terminal, it can reach any coordinate point in space
The manipulator has strong universality, can adapt to a variety of operations, good manufacturability and easy maintenance and adjustment.
