[0003] Processes such as thin film processing and vapor deposition on mother glass substrates require an extremely high level of cleanliness and must therefore be performed in a vacuum environment. Robotic arms moving in a vacuum must have seals built into each joint to prevent air and dust from escaping from within the arm. However, these seals hinder the arm's movement, often resulting in a limited degree of freedom in joint motion.
[0004] During the production process of glass substrates, they often need to be transported. The transport work is generally completed by a robotic arm. In the process of lifting and lowering the glass substrates, due to the thin glass substrates, they will form a sag between the forks of the robotic arm, causing them to slide on the forks, resulting in scratches and damage to the glass. Subsequently, the glass substrates will be damaged or have a poor appearance in subsequent processes, reducing the product yield. Summary of the Invention
