Main characteristics and applications of parallel robot
Parallel robots have emerged as early as the 1990s, and now they are a new generation of industrial robots, which are widely used in light industries such as medicine and electronics. This article introduces its classification, application fields and other related knowledge.
Main characteristics of parallel robot
1. No accumulated error, high accuracy;
2. The driving device can be placed on or near the fixed platform, so that the moving part has light weight, high speed and good dynamic response;
3. Compact structure, high rigidity and large bearing capacity;
4. The fully symmetric parallel mechanism has better isotropy;
5. Small working space;
According to these characteristics, parallel robots have been widely used in the fields that need high stiffness, high accuracy or large load without large workspace.
Main applications of parallel robot
Parallel mechanisms are mostly used in occasions requiring high stiffness, high accuracy, high speed and no large space. Specific applications include:
1. Sorting, handling and packing in food, medicine, electronics and chemical industries.
2. Simulated movement: such as the pilot's three-dimensional space training simulator; Engineering simulator, such as marine swing table; Test the operation reliability of products under simulated repeated impact and vibration; Entertainment Sports simulator.
3. Parallel machine tool
4. Docking action: such as space docking of spacecraft; Wheel installation on automobile assembly line; Prosthetic limb osteosynthesis in hospital.
5. Bearing movement: such as large torque bolt tightening; Short distance load handling.
6. Metal cutting: it can be applied to various milling machines, grinding machines, drilling machines, spot welding machines and cutting machines.
7. It can be used for measuring machines and error compensators of other mechanisms
8. Micro manipulation robot: used for micro mechanism or micro mechanism
9. Robot joints: they can be used as joints of robots, crawling mechanisms, food, medical packaging and transfer robots.
