AI Technical Summary

Technical Problem

In the wafer processing process, the connection structure of the robotic arm has unstable transmission performance in humid environments and has high requirements for sealing and waterproofing, resulting in a scarcity of domestically produced equipment.

Method used

A long-line drive structure is formed by toothed belts, and the first and second toothed belts are used to drive between the forearm and the upper arm. Combined with isolation bearings and sealing gaskets, the transmission stability and sealing are ensured, and complex transmission can be completed with only a single drive source.

Benefits of technology

It achieves efficient and precise wafer transfer in humid environments, with a simple structure, stable transmission, and good sealing and waterproofing effect, making it suitable for transmission in humid environments.
