Compact low-friction heat production mechanical arm suitable for rapid sorting of devices

The invention provides a compact type low-friction heat production mechanical arm suitable for rapid sorting of devices, and relates to the technical field of mechanical arms. The mechanical arm comprises a mechanical arm body, a wire harness guide block, a plurality of air pipes and a plurality of servo mechanisms, the wire harness guide block is connected with the mechanical arm body, and a plurality of guide holes are formed in the wire harness guide block in the vertical direction; each servo mechanism comprises a suction nozzle and a servo motor, and the suction nozzles and the servo motors are arranged on the mechanical arm body. The ends, away from the suction nozzles, of the air pipes located on the two sides penetrate through the corresponding guide holes from bottom to top, pass through the side faces of the servo motors and then are connected to the mechanical arm body, and the end, away from the suction nozzles, of the air pipe located in the middle penetrates through the corresponding guide holes
