[0036] like Figure 5 As shown, the pushing bracket 502 is also provided with a seventh driving assembly that cooperates with the second push rod 503. The seventh driving assembly includes a third cylinder 507 and a third piston rod 508 arranged at the output end of the third cylinder 507. The third cylinder 507 drives the third piston rod 508 to move along the X-axis direction and the end of the third piston rod 508 away from the third cylinder 507 cooperates with the second push rod 503. The third cylinder 507 drives the third piston rod 508 to move, so that the second push rod 503 can be moved under the drive of the third piston rod 508, and when the third piston rod 508 extends out of the third cylinder 507, the second push rod 503 extends into the groove to push the lens holder 200 in the detection chamber 301 into the second accommodating groove, and when the third piston rod 508 retracts into the third cylinder 507, the second push rod 503 is reset, and the third piston rod 508 is driven to move back and forth by the third cylinder 507, so that the lens holder 200 in the detection chamber 301 can be continuously loaded into the second material box 501.

[0037] In detail, the pusher bracket 502 is further provided with a fifth guide rail 509, the length direction of the fifth guide rail 509 is parallel to the X-axis direction, and the second push rod 503 is provided with a fifth slider matched with the fifth guide rail 509. The fifth guide rail 509 provided on the pusher bracket 502 is used to guide the second push rod 503 to move on the pusher bracket 502, ensuring that the second push rod 503 smoothly enters the slot, and preventing the second push rod 503 from deviating from the preset direction to cause the lens bracket 200 to fall from the detection bracket 300.

[0038] Please refer to Figure 2 and Figure 3 In the present embodiment, the diameter and depth of the positioning groove 201 on the lens holder 200 are adapted to the size of the optical lens to be detected. When detecting optical lenses of different sizes, it is sufficient to replace the lens holder 200 with the matching positioning groove 201, which is beneficial to improving the versatility of the optical lens automatic detection device.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
