[0015] See also Figure 1-6 The present invention provides a technical solution: an optical lens test platform, comprising four symmetrically arranged support legs 11 and a test platform 10 fixedly mounted on the upper surfaces of the four support legs 11, a groove 20 is provided at the center of the upper surface of the test platform 10, a chuck assembly 30 is provided inside the groove 20, an L-shaped support frame 40 is fixedly mounted on one side of the upper surface of the test platform 10, a cylinder 50 is provided at the bottom end of the end of the L-shaped support frame 40, a light source lamp 60 is provided at the end of the cylinder 50, the light source lamp 60 is located just above the chuck assembly 30, and the distance between the light source lamp 60 and the optical lens is adjusted by the cylinder 50, so as to facilitate the detection of the optical lens; The chuck assembly 30 includes a placing table 31 fixedly installed in the groove 20, and four strip grooves 32 are symmetrically opened on the side of the placing table 31, and clamping blocks 33 are slidably installed inside the four strip grooves 32, wherein vertical plates 34 are fixedly installed on the outer sides of the bottom ends of two opposite clamping blocks 33, and two symmetrical electric push rods 35 are arranged between the two vertical plates 34; A servo motor 36 is fixedly installed at the center of the bottom end of the inner wall of the groove 20, and a rotating shaft 37 is provided at the end of the servo motor 36, and a connecting plate 38 is provided at the end of the rotating shaft 37. Arc-shaped connecting rods 39 are rotatably installed at the four corners of the lower surface of the connecting plate 38. The four arc-shaped connecting rods 39 are rotatably connected to one side of the bottom end of the four clamping blocks 33 in turn. By placing the optical lens at the center of the surface of the placement table 31, starting the servo motor 36, the rotating shaft 37 drives the connecting plate 38, the arc-shaped connecting rod 39 and the clamping block 33 to move equidistantly toward the center of the placement table 31. When the clamping block 33 moves inward, the electric push rod 35 is synchronously extended and retracted, thereby clamping the optical lens.

[0016] Among them, sliding grooves are provided on both sides of the inner walls of the four strip grooves 32, and sliding blocks cooperating with the sliding grooves are provided on both sides of the four clamping blocks 33. The four clamping blocks 33 are slidably installed inside the strip grooves 32 through the cooperation of the sliding blocks and the sliding grooves, so that the clamping blocks 33 move equidistantly toward the center of the placement table 31, thereby clamping the optical lens.

[0017] The upper surface of the connecting plate 38 does not contact the lower surface of the placing platform 31 , so that the connecting plate 38 is kept independent and does not affect the rotation of the connecting plate 38 .

[0018] Among them, the upper surface of the arc connecting rod 39 does not contact the lower surface of the connecting plate 38, and the lower surface of the arc connecting rod 39 does not contact the upper surface of the electric push rod 35, so as to keep the connecting plate 38 and the arc connecting rod 39 independent so as not to affect the rotation of the connecting plate 38.

At this time, the clamping area of ​​the chuck assembly 30 is the smallest, and the minimum clamping area of ​​the chuck assembly 30 is smaller than the surface area of ​​the optical lens to ensure that the optical lens can be clamped.

[0020] Among them, when rotating to the end and tail of the same arc-shaped connecting rod 39 corresponding to each other, the clamping area of ​​the chuck assembly 30 is the largest, the telescopic length of the electric push rod 35 is the longest, the clamping block 33 is away from the end of the inner wall of the strip groove 32, and the clamping block 33 is close to the edge of the placement table 31. The maximum clamping area of ​​the chuck assembly 30 is larger than the surface area of ​​the optical lens to ensure that the optical lens is easy to take.

[0021] Working principle: When in use, by placing the optical lens at the center of the surface of the placement table 31, starting the servo motor 36, the rotating shaft 37 drives the connecting plate 38, the arc connecting rod 39 and the clamping block 33 to move equidistantly toward the center of the placement table 31, while the clamping block 33 moves inward, the electric push rod 35 synchronously extends and retracts to clamp the optical lens. After the optical lens is clamped, the distance between the light source lamp 60 and the optical lens is adjusted by the cylinder 50, thereby facilitating the detection of the optical lens.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
