Description

Technical Field

[0001] The utility model relates to the technical field of detecting light sources, in particular to a point light source with a small volume and a linear light path. Background Art

[0002] With the increasing demands of the 3C industry, the inspection requirements for the dimensions and appearance of some high-end products are becoming increasingly stringent. As a result, the precision and structural miniaturization requirements of the automated equipment (or the machines and inspection devices within the automated equipment) used to process and produce these high-end products are becoming increasingly stringent. To ensure the precision and structural miniaturization requirements of these automated equipment or devices, the use of inspection light sources is indispensable. The inspection light sources can provide a good illumination area in these automated equipment or devices, thereby ensuring the accurate operation of the inspection devices or automated devices.

[0003] At present, there are two types of detection light sources: laser light sources and linear light sources. Laser light sources have defects such as short life, complex installation, high price and limited usage conditions. At present, linear light sources are usually used as detection light sources in the market.

[0004] However, with the growing demands of the 3C industry, if linear light sources want to meet the requirements of the irradiated light area, they will have the disadvantage of being large in size and difficult to install on precision detection equipment.

[0005] Therefore, the field of automated inspection currently lacks a detection light source that is compact and has a linear optical path with a good illumination area. (Currently, there is no detection light source with this combination, but there are corresponding optical structures. However, these optical structures are complex in composition and assembly, still relatively large in size, and lack good application scenarios. Therefore, we will not elaborate on them here. This related optical structure is referenced in patent document number: CN214369453U, and the patent name is: Chinese Utility Model Patent for a Coaxial Point Light Source.) Summary of the Invention

The first linear light path and the second linear light path are superimposed to form a planar linear light path.
