I. Main characteristics of parallel robots
1. No cumulative error, high accuracy;
2. The drive unit can be placed on or near a fixed platform, which makes the moving parts lightweight, high-speed, and with good dynamic response;
3. Compact structure, high rigidity, and large load-bearing capacity;
4. Completely symmetrical parallel mechanisms have good isotropy;
5. Small workspace;
Based on these characteristics, parallel robots have been widely used in fields that require high rigidity, high precision, or large loads but do not require a large workspace.
II. Main Applications of Parallel Robots
Parallel mechanisms are often used in applications requiring high rigidity, high precision, and high speed, but without the need for large spaces. Specific applications include:
1. Sorting, handling, and packing in the food, pharmaceutical, electronics, and chemical industries.
2. Simulated sports: such as 3D space training simulators for pilots; engineering simulators, such as marine swing platforms; testing the operational reliability of products under simulated repeated impacts and vibrations; recreational sports simulation platforms.
3. Parallel machine tools
4. Docking actions: such as space docking of spacecraft; wheel installation on an automobile assembly line; and prosthetic bone setting in a hospital.
5. Load-bearing motion: such as tightening high-torque bolts; short-distance heavy object handling.
6. Metal cutting: Applicable to various milling machines, grinding machines, drilling machines, spot welding machines, and cutting machines.
7. Can be used in measuring machines as an error compensator for other mechanisms.
8. Micro-manipulation robots: used for micro-motion mechanisms or micro-mechanisms.
9. Robot joints: can be used as joints for robots, crawling mechanisms, food and pharmaceutical packaging, and transfer manipulators, etc.
