[0034] A power member for driving the internal thread sleeve 10 to rotate;

[0035] During detection, the stepper motor 2 drives the mounting plate 17 to rotate, and the mounting plate 17 drives the internal thread sleeve 10 and the external thread rod 11 to revolve, and the external thread rod 11 drives the side camera 16 to rotate around the glass bottle, and collects the surface image of the glass bottle in the circumferential direction. At the same time, the power part drives the internal thread sleeve 10 to rotate, and the internal thread sleeve 10 drives the external thread rod 11 to move in the vertical direction, so that the side camera 16 moves in the vertical direction. At the same time, the side camera 16 collects images in the height direction of the glass bottle, and the detection is comprehensive and more accurate.

[0036] Wherein, the power part comprises:

[0039] It can be understood that when the mounting plate 17 is driven to rotate by the stepping motor 2, the mounting plate 17 drives the internal thread sleeve 10 to rotate around the gear ring 8, so that the gear 9 rotates around the gear ring 8. Since the gear 9 is meshed with the gear ring 8, the gear 9 rotates, and the gear 9 drives the internal thread sleeve 10 to rotate, and the internal thread sleeve 10 drives the external thread rod 11 to move up and down, so that the external thread rod 11 drives the side camera 16 to move up and down;
