The output end of the screw feeding mechanism 2 is connected to the input end of the guide rail assembly 4, and the screws will be transported from the screw feeding mechanism 2 to the guide rail assembly 4. The straight vibrator 3 is used to make the screws on the guide rail assembly 4 move in a straight line. When the screw moves to the end of the guide rail assembly 4, the dividing mechanism 8 pushes the screw out, and the multi-station feeding mechanism 9 transfers the screw. When the screw on the guide rail assembly 4 passes through the visual inspection component 5, the visual inspection component 5 then inspects the appearance of the screw. When the inspection is qualified, the screw passes through the rejection component 6. When the inspection is unqualified, the rejection component 6 rejects the screw.
