Problems solved by technology

[0004] However, because the lens module to be dispensed is not easy to be accurately fixed and other factors, it is difficult to achieve precise dispensing, which affects the assembly yield
Therefore, the dispensing process is generally the bottleneck of assembly yield.

Abstract

The invention relates to a dispensing fixture which is used for positioning a lens module to be dispensed. The dispensing fixture comprises a tray, a cover body, an L-shaped block and a pushing block. The tray is internally provided with a depression for containing the lens module. The cover body is provided with a through hole which is corresponding to the depression, and the cover body is matched with the tray to fix the lens module. The block is used for positioning the tray and the cover body. The pushing block is used for resisting the adjacent two sides of the tray and the cover body at the block for fixation. The dispensing fixture of the invention has simple structure, the pushing block can be matched with the block for positioning the tray and the cover body, thus accurately positioning the lens module and further improving the dispensing accuracy and the assembly yield.

Description

technical field [0001] The invention relates to the technical field of lens module assembly, in particular to a lens module glue dispensing jig. Background technique [0002] In recent years, with the development of optical products, the scope of application of lens modules continues to expand, such as digital cameras, mobile phones with camera functions and other electronic products. For electronic products, especially consumer electronic products, the development trend is light weight and thinner, and the corresponding lens modules installed therein are also becoming smaller and smaller, and the requirements for precision are also getting higher and higher. Therefore, the assembly process of the lens module also requires higher accuracy and stability to ensure assembly efficiency and assembly yield. [0003] Lens modules usually include lens barrels, lens groups, spacer rings and filters. The lens group, the spacer ring and the optical filter are sequentially fixed in th...
