The fourth, fifth and sixth axes 14, 15, 16 constitute the wrist joint of the robot arm. The mechanical fork is laterally mounted at the end of the sixth shaft 16, and the working space of the mechanical arm is relatively large compared to a mechanical fork vertically mounted at the end of the sixth shaft 16. In order to ensure that the roll angle and the pitch angle are unchanged during the operation of the robot arm, the sixth axis 16 remains unchanged. And along with the rotation of the fifth shaft 15, the probability that the fourth shaft 14 and the sixth shaft 16 are parallel is higher, at this time, a wrist singular point is generated on the mechanical arm, and the fifth shaft 15 generates sudden changes of speed and posture, so that the posture of the tail end of the sixth shaft 16 is uncontrollable (a wafer box is broken), and even the mechanical arm is damaged.
