Description

A lens assembly jig

technical field

The utility model belongs to the technical field of jigs, in particular to a lens assembly jig.

Background technique

In mobile lighting equipment, it is often necessary to use two lenses to shape the light. Traditional manufacturers only carefully position and fix the lenses one by one when assembling the finished lighting equipment, and the assembly efficiency is low. The manufacturer chooses to design the two lenses as an inner lens and an outer lens. An assembly position for assembling the inner lens extends from the edge of the outer lens. Relatively fixed, when assembling the finished product, it can be put into the housing of the lighting equipment as a part, reducing the number of steps, thereby improving the efficiency of assembling the finished product, and at the same time ensuring that the two lenses will not be loose, so that the light after shaping by the lens is not affected. The formed light spot is more stable; due to the current method of assembling the inner lens to the assembly position of the outer lens, most of them are manually installed, and the assembly efficiency is low. For some relatively small lenses, it is more inconvenient to work with gloves. Without gloves, it is easy to get fingerprints.

Therefore, there is an urgent need for a jig that can improve the efficiency of assembling the inner lens into the outer lens.
