[0008] In the above-mentioned ear shaft defect identification device based on machine vision technology, this scheme allows the transparent detection inner disk to rotate circumferentially in the groove, so that the side position of the ear shaft body on the transparent detection inner disk can be displaced in a circle, so that it cooperates with the camera area on the side, so that the ear shaft body can achieve a full range of detection effects through three camera mechanisms.

[0009] As a further improvement of the present application, the sponge strip is filled with lubricating oil, and a plurality of protruding vertical shafts are fixedly connected to the upper end of the matching gear.

[0015] In summary, in this scheme, a gear bar is arranged on the base circular plate. When the transparent detection inner disc is transported to the gear bar, the gear bar and the camera mechanism position correspond. The transparent detection inner disc can contact and mesh with the gear bar through the matching gear below it, so that the transparent detection inner disc rotates circumferentially in the slot, and the side position of the ear shaft body on the transparent detection inner disc can be displaced in a circle, so that it can cooperate with the camera area on the side, so that the ear shaft body can achieve a full range of detection effects through three camera mechanisms. At the same time, in the process of contact between the gear bar and the matching gear, a sponge bar body can also be arranged on the gear bar. The protruding vertical axis on the matching gear and the sponge bar body are squeezed and contacted with each other, and the lubricating oil liquid soaked in the sponge bar body is squeezed out and dripped between the meshing surfaces between the matching gear and the gear bar, which can make the connection between the matching gear and the gear bar smoother, which is beneficial to ensure the smooth rotation of the transparent detection inner disc.
