During the process of the sample conveyor belt 8 sending the battery terminals 30 to the rotary conveyor inspection device 4, the battery terminals 30 enter the top surface of the inspection ring 411 along the guide slope. The rotary rotation mechanism 42 drives the inspection rotary table 41 to rotate, so that each battery terminal 30 on the top surface of the inspection ring 411 is guided to the correct position by the guide channel 432, ensuring that each battery terminal 30 on the top surface of the inspection ring 411 can pass through the upper and lower end face inspection unit 44, the center hole inspection unit 45, the upper surface inspection unit 46, and the edge inspection unit 47 in sequence to complete the appearance inspection of the battery terminals 30.

The good product transfer device 16 moves back and forth between the good product conveyor belt 9 and the good product collection device 10 to pick up and put in the battery terminals 30, thereby transferring the battery terminals 30 from the transport surface of the good product conveyor belt 9 to the material tray body 29 provided by the good product collection device 10. The good product collection device 10 is used to collect the material tray body 29 loaded with battery terminals 30.

[0040] The defective conveyor belt 131 delivers the defective battery terminals 30 to the discharge side of the defective conveyor belt 131. The defective transfer device 18 moves back and forth between the defective conveyor belt 131 and the defective collection device 121 to pick up and put in the battery terminals 30, thereby transferring the battery terminals 30 from the transport surface of the defective conveyor belt 131 to the tray body 29 provided by the defective collection device 121. The defective collection device 121 is used to collect the tray body 29 containing the battery terminals 30. If the defects of the defective battery terminals 30 collected in this tray are extremely minor, the collected defective battery terminals 30 can be further processed into usable finished battery terminals 30.

[0041] refer to Figure 3 At least one transport guide plate 26 is provided on the transport surface of the test product transport belt 8, the transport surface of the good product transport belt 9, and the transport surface of the defective product transport belt 131. The transport guide plate 26 has a transport guide slope 2601 for guiding the battery terminal 30, thereby adjusting the position of the battery terminal 30.

[0042] A stacking sensing device 27 and a terminal pusher 24 are provided on the transport surface of the test conveyor belt 8, and an upward-facing collection channel 28 is provided below the test conveyor belt 8. The stacking sensing device 27 is used to detect whether the battery terminals 30 are stacked. The stacking sensing device 27 can be a visual inspection camera or a laser displacement sensor. When the stacking sensing device 27 detects that the battery terminals 30 are stacked, the terminal pusher 24 pushes the battery terminals 30 into the collection channel 28 by jetting air.

[0043] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
