The Main Features And Application Details Of Parallel Robots

Parallel robots have emerged as early as the 1990s, and now they are the new generation of industrial robots. They are widely used in light industries such as medicine and electronics. This paper introduces its classification, application fields and other relevant knowledge.

I. Main characteristics of parallel robot

1, no cumulative error, high accuracy;

2, the driving device can be placed on the fixed platform or close to the position of the fixed platform, so that the moving part of light weight, high speed, good dynamic response;

3, compact structure, high stiffness, large bearing capacity;

4. The fully symmetrical parallel mechanism has good isotropy;

5. Small working space;

According to these characteristics, parallel robots have been widely used in the fields requiring high stiffness, high precision or large load without large workspace.

Two, the main application of parallel robot

Parallel mechanism is mainly used for occasions requiring high stiffness, high precision, high speed and no large space. Specific applications include:

1, food, medicine, electronics, chemical industry sorting, handling, packing, etc.

2. Simulated movement: such as pilot 3d space training simulator; Engineering simulator, such as Marine swing platform, etc. Test the running reliability of the product under the simulated repeated impact and vibration; Entertainment and sports simulator.

3. Parallel machine tools

4, docking action: such as space docking spacecraft; Wheel installation on automobile assembly line; Prosthetic osteosynthesis in hospital.

5, bearing movement: such as high torque bolt fastening; Short distance heavy lifting.

6, metal cutting processing: can be applied to all kinds of milling machine, grinding machine drilling machine or spot welding machine, cutting machine.

7, can be used for measuring machine, used as the error compensator of other institutions

8. Micro-operated robot: used for micro-mechanism or micro-mechanism

9, robot joints: can be used as robot joints, crawling mechanism, food, medicine packaging and shifting manipulator.
