[0028] Working principle:

[0029] Optical lens surface limit detection work:

[0030] When the optical lens surface shape needs to be detected, the optical lens is placed between the wool pad 11 and the plurality of straight rods 10 (such as Figure 3 ), the external power supply of the second motor 206 is turned on, the second motor 206 starts to drive the stud 202 to rotate in the second box body 201 through the bearing, the rotation of the stud 202 drives the two nuts 203 to slide relatively in the slideway processed on the inner wall of the second box body 201, and the two nuts 203 respectively drive the first box body 204 to move relatively, so that the plurality of straight rods 10 drive the rubber pad 9 to move relatively;

[0031] When the multiple rubber pads 9 are against the surface of the optical lens, the multiple straight rods 10 will compress the first springs 205 respectively. When the multiple straight rods 10 are against the surface of the optical lens, the second motor 206 stops rotating. In this way, the multiple first springs 205 can be used to push the straight rods 10 to limit the optical lens. Then, the external power supply of the hydraulic cylinder 8 is turned on. The hydraulic cylinder 8 starts to drive the fourth box 101 to move to the right, thereby driving the multiple round rods 102 to move to the right. When the multiple round rods 102 correspond to the top of the optical lens, the hydraulic cylinder 8 stops moving, and then the external power supply of the first motor 7 is turned on.

[0032] The first motor 7 starts and drives the threaded rod 4 to rotate in the third box body 5. The rotation of the thread 4 drives the threaded seat 6 to slide downward in the slideway processed on the inner wall of the third box body 5 through the surface protrusion, thereby driving the fourth box body 101 and the multiple round rods 102 to move downward through the hydraulic cylinder 8. When the multiple round rods 102 are against the surface of the optical lens through the rubber block 105, the hydraulic cylinder 8 stops moving, and the multiple round rods 102 compress the spring 103 through the protrusion on the surface of the optical lens. At the same time, the multiple round rods 102 will drive the scale 104 to move upward in the frame 106. In this way, the height of the scale 10 in the middle and on both sides can be clearly seen to determine whether the curvature of the optical lens meets the working standards.

[0033] When you need to replace optical lenses of different sizes;

[0034] The second motor 206 is controlled to reverse to reset the plurality of straight rods 10, and the first motor 7 is controlled to reverse to reset the plurality of round rods 102. The optical lenses are then taken out and optical lenses of different sizes are placed, and then the detection work is performed in accordance with the above working method.

[0035] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
