Technical Field

[0001] The utility model relates to the technical field related to optical lens positioning, in particular to a positioning mechanism of an optical lens coupling machine. Background Art

[0002] An optical lens is an optical element with a spherical surface made of transparent material. It plays an important role in astronomy, military, medicine and other fields. In the production process of optical lenses, it is generally necessary to use a coupling machine to assemble the optical lenses in a coupled manner, and the positioning mechanism is an indispensable part of the coupling machine.

[0003] In the prior art, in a patent application entitled "A Positioning Mechanism of an Optical Lens Coupling Machine" with an authorization publication number of CN212735796U and an authorization publication date of 2021-03-19, a clamping mechanism is set at the bottom of the positioning platform, and the pull rod is loosened to allow the clamping spring to rebound and push the clamping block out of the fixed block, so that the clamping block is clamped at the front and rear ends of the optical lens to be coupled, and the positioning knob is turned clockwise to drive the threaded rod and the internal thread block to rotate in coordination, and the internal thread block drives the positioning block to move inward at the moving groove, and then the positioning block is clamped at the left and right sides of the optical lens to be coupled, thereby achieving precise positioning of optical lenses of different sizes to be coupled, improving the qualified rate of finished products, and avoiding unnecessary increase in production costs;

[0004] During the actual use of the above device, the threaded rod is rotated to drive the positioning block to clamp the optical lens to be coupled. However, during this process, the threaded rod needs to be rotated multiple times, which is inefficient and affects the work progress. In addition, the front and rear sides of the optical lens are positioned by clamping blocks connected to springs, which have poor stability.

[0005] Therefore, we propose a positioning mechanism for an optical lens coupling machine in order to solve the above-mentioned problems. Utility Model Content
