Problems solved by technology

Therefore, it is time-consuming and difficult to select the components required to match the lens modules of different designs from the components formed by different mold cavities in different molds, thereby reducing production efficiency
In addition, in the injection-molded components, there may be too large gap width between the assembled components, which exceeds the requirement of the lens module for the gap width. At this time, the component may be abnormal.
However, it is currently impossible to judge whether the gap width of the lens module component group meets the assembly requirements through testing in time, so that the injection machine may continue to mold abnormal components, reducing the assembly utilization rate of the final molded components, resulting in a decrease in yield

Abstract

The invention provides a method for testing assembly elements of a lens module. The method comprises the following steps: an element set of the lens module is provided; the element set comprises at least two elements provided with bosses for assembly; the bosses of the elements for assembly are blocked up with each other; and the element set of the lens module are clamped to test the gap width between the two elements for assembly. The method has simple operation, and can improve the efficiency of subsequent assembly operation.

Description

technical field [0001] The invention relates to the technical field of lens modules, in particular to a method for testing assembly components of a lens module. Background technique [0002] The lens module is to assemble the lens module components such as lens, spacer, spacer ring, infrared cut filter into the lens barrel, so that the lens, spacer, spacer ring, infrared cut filter and other components in the lens barrel The lens barrels are coaxially arranged to realize imaging. Due to the increasing demand for lens modules in light, thin and miniaturized electronic products, especially in portable devices such as notebook computers and mobile phones, when producing the components of the lens module, it is necessary to satisfy the small size of the product and at the same time, High precision, low cost, etc. have also become the goals pursued by people. [0003] Because the injection molding method can directly form plastic products, the molding cycle is short, and the p...
