Quick dispensing device for lens module group assembling

Abstract

The invention provides a glue dripping device used in a lens module assembly; the glue dripping device comprises a glue storage chamber; the glue storage chamber has at least one glue outlet and a bottom part; the glue dripping device also comprises at least one fixing part; the fixing part is positioned on the outer surface of the bottom part. The glue dripping device used in a lens module assembly can accurately position the position on the lens module group on which glue is to be dripped, which avoids the impact on glue dripping quality caused by the uneven glue dripping caused by the inaccurate counter position and guarantees the glue dripping quality.

Description

Technical field [0001] The invention relates to a glue dispensing device, in particular to a glue dispensing device which can be used for assembling a lens module. Background technique [0002] A lens module applied to a camera or optical instrument is usually composed of a lens barrel with optical components and a lens holder. See figure 1 , Is a lens module 100, which includes a lens holder 10, a lens barrel 20, a lens group 21, a spacer ring 22, and a filter 23. The lens group 21, the spacer ring 22, and the filter 23 are sequentially along the optical axis Fixed in the lens barrel 20, the filter 23 is arranged on the outermost side of the lens barrel 2. The outer wall of the lens barrel 20 and the inner wall of the lens holder 10 are provided with threads, and the lens barrel 20 is fixed to the lens holder 10 through the threads. [0003] In the assembly process of the lens module, a glue dispensing process is generally used to fix the filter on the inner wall of the lens ba...

Problems solved by technology

However, this method has many problems in automatic dispensing. For example, the dispensing device needs to be positioned multiple times, which is not only time-consuming, but also easily leads to inaccurate alignment of the dispensing device, making dispensing invalid and affecting the quality of dispensing, which in turn will cause It directly affects the quality of the lens module, because one of the reasons why the lens module fails during use is that the filter in the lens module falls off

When the lens module is assembled, especially when the filter is fixed on the inner wall of the lens barrel, if dispensing quality problems such as uneven dispensing and insufficient dispensing amount occur, it will seriously affect the relationship between the filter and the inner wall of the lens barrel. Adhesion between

Due to the weak adhesion between the filter and the inner wall of the lens barrel, the probability of lens module failure due to the loss of the filter during use will be greatly increased
