The force-saving arm manipulator has the following main features:

1. Labor-saving design. Adopting pneumatic-hydraulic mixing or pneumatic compensation principle, and setting the slider mechanism, only a small force is needed to drive the arm movement during operation, which greatly reduces the operator's labor intensity.

2. High load and high precision. Pneumatic-hydraulic hybrid or pneumatic drive system can produce large thrust, can manipulate heavier objects; and high position accuracy, suitable for precision operation.

3. Speed adjustable. By adjusting the air output pressure or compensation fluid flow, the arm movement speed can be adjusted to meet the requirements of different operating environments and precision.

4. Energy-saving and environmental protection. Pneumatic or pneumatic-hydraulic energy drive, no electric control and motor, more energy-saving and environmental protection.

5. Easy maintenance. Pneumatic system structure is simple, less parts, maintenance is easier to operate.

6. Higher price. Due to the more complex structure and technology, the parts and materials involved in the higher cost, the price is higher than the all-electric drive.

7. Poor mobility. Compressed air entry port and hydraulic cylinder are required, and it is more difficult to move and install.

In summary, labor-saving arm manipulator operation labor-saving, load and high precision, adjustable speed, energy saving and environmental protection, is a more ideal high-performance manipulator products. However, due to the more complex technology and structure, high price and poor mobility, mainly for fixed assembly line production.

In the selection and management, according to the specific operating environment and requirements to choose the correct mechanism form and parameters. Regularly test the air pressure, slider movement and position accuracy, etc. to ensure normal working condition. Regularly maintain the air circuit to discharge impurities and ensure the sealing performance. Lubricate the slider and the articulated part of the arm to reduce the resistance to movement and wear. Reasonably set the loading and unloading speed and path planning during operation to maximize its labor-saving and high-precision characteristics.

Compared with the all-electric manipulator, the power method of the labor-saving arm manipulator is more environmentally friendly and energy-saving, and the operation is more humane, but the technology is also more complicated and more costly, and the mobile performance is poorer. According to the different use environment and requirements, choose the more compatible robot products. Labor-saving arm manipulator not only improves operational efficiency, but more importantly, reduces labor intensity, and belongs to the high-performance and highly humanized automation products and equipment.
