[0020] like Figure 1 to Figure 7 As shown, the use principle of the present invention is: The entire detection mechanism uses the frame as the support platform. The feed assembly is responsible for transporting the ball cage holder workpiece to be inspected to the designated position in an orderly manner. The gripper assembly 1 in the transfer assembly accurately grabs the workpiece on the feed assembly and transfers it to the inspection table. After the motor of the detection assembly is started, it drives the connecting rod module to move synchronously, and then drives the sensor module corresponding to the connecting rod module on each group to move along the guide rail of the inspection table to the workpiece.
