Production method of light source module

Abstract

The invention provides a production method of a light source module. The light source module at least comprises a substrate, light source elements and a lens cover. The production method includes: providing at least one pad and a marked substrate; printing solder paste on the corresponding pad; disposing the light source elements on the pad correspondingly; melting the solder paste to weld the light source elements on the pad; acquiring first offset of the center of each light source element, relative to a marked first direction; dispensing glue at positions of the substrate, to be glued; correspondingly disposing the lens cover at the positions to be glued to cover above the light source elements; melting the glue to fix the lens cover on the substrate; acquiring second offset of the center of the lens cover, relative to the marked first direction; when a first difference between the first offset and the second offset in the first direction, namely a first offset distance between the centers of each light source element and the lens cover, is not larger than a first reference distance, subjecting the light source module to function testing; if yes, re-producing the light source module.

Description

technical field [0001] The invention relates to a method for manufacturing a light source module, in particular to a method for manufacturing a light source module that simplifies the process and reduces the cost. Background technique [0002] As the manufacturing cost of the electronics industry continues to increase, the manufacturing cost of some light source modules such as diode light bars is no exception. In the manufacturing process of the existing light source module, especially for the manufacture and production of the light source module with a lens cover, it is necessary to conduct a center alignment test (Tilt Test) on the finished product, that is, to measure the Whether the offset distance between the center and the center of the lens cover is within the preset range value, so as to ensure the assembly accuracy of the shipped products. However, the cost of the center alignment machine used for this test is high, and the cost of subsequent maintenance is also h...

AI Technical Summary

Problems solved by technology

However, the cost of the central alignment machine used for this test is relatively high, and the cost of subsequent maintenance is also high. Therefore, using such a device for measurement and testing will inevitably increase the burden on the manufacturing enterprise.

However, if this test is not carried out, the assembly accuracy of the shipped products will not be guaranteed. Therefore, this situation puts the manufacturer in a dilemma
