Description

Technical Field

[0001] The present application relates to the technical field of field lens assembly, and in particular to an achromatic field lens assembly tool. Background Art

[0002] An achromatic field mirror is an optical element that is primarily used to correct the chromatic aberration between laser wavelengths (such as 355nm) and visual wavelengths (such as the common 633nm). The achromatic field mirror contains multiple lenses that are arranged in a combination to make the laser and visual imaging light completely coaxial and focused to the same point, so that their focal planes coincide. Therefore, when processing an achromatic field mirror, the lenses inside the achromatic field mirror need to be assembled.

[0003] The Chinese patent with announcement number CN206348283U, named "A Lens Group Assembly Tool", specifically, when assembling the lens, turn on the light source, and the light from the LED lamp beads is concentrated through the lens into the light guide tube; the lens is placed on the top of the light guide tube, and through the illumination of the light source, the naked eye can clearly identify whether there is dust on the surface of the lens. Each time a lens is stacked, it is observed; after confirming that all stacked lenses are free of dust, the lens barrel is put on the lens group, and then the baffle is locked at the end of the lens barrel to complete the assembly of the lens group.

[0004] The above-mentioned prior art can also realize the function of assembling lenses when in use. However, when assembling lenses, the above-mentioned prior art only determines whether there is dust on the lens surface by visual observation. It cannot press and fix the lenses, nor can it accurately adjust the distance between the lenses. At the same time, it cannot automatically assemble the lenses, and the assembly efficiency is low. Based on this, there is still room for improvement on the basis of the existing achromatic field mirror assembly tooling. Utility Model Content

Afterwards, the spacing between the lenses inside the positioning frame 20 is adjusted by the adjustment component 5, thereby achieving the function of assembling the achromatic field mirror. The assembly effect is good, the positioning is accurate, manual operation is reduced, and the assembly efficiency is improved.

[0026] See Figure 1-3 As shown, as the preferred technical solution of this embodiment, the positioning assembly 2 includes a guide rail 21 and a positioning bracket 22. The upper end of the base plate bracket 1 is symmetrically provided with grooves, and the guide rail 21 is installed in the groove. A positioning bracket 22 is installed between the upper ends of the two guide rails 21, and the upper end of the positioning bracket 22 is provided with a positioning groove that cooperates with the positioning bracket 20.

The front and rear sides of the upper end of the base plate bracket 1 are loading stations. When one positioning bracket 22 is in the middle of the lower end of the mounting bracket 3, the other positioning bracket 22 is at the loading station, which is convenient for placing the positioning bracket 20 and the lens to be assembled inside the positioning bracket 22, and also convenient for taking out the assembled positioning bracket 20 and the lens.
