Problems solved by technology
At present, during the processing of micro-biological intelligent structured light modules (with a size below 5.0mm×5.0mm×4.7mm), especially when the laser diode and the lens are focused, it is easy to cause the collimated spot to become larger or smaller, resulting in focusing Blurring, which affects the image quality, because the focus effect of the two parts cannot be confirmed during the assembly process, resulting in defects and material scrapping problems

The invention discloses an LD (laser diode) focusing jig of a 3D imaging module for minitype biological intelligent structural light. The LD focusing jig comprises a copper part assembly fixing block,an LD positioning lighting base and a coaxial lead screw motion device, wherein the copper part assembly fixing block is used for fixing a copper part assembly with a lens; the LD positioning lighting base can be driven by the coaxial lead screw motion device to be moved in the direction close to or away from the copper part assembly fixing block; an LD fixing column and LD positioning holes areformed in the LD positioning lighting base; a conducting wire pin for lighting LD is arranged in the LD fixing column; a circular light-transmission through hole is formed in the copper part assemblyfixing block and is coaxial to the LD fixing column; a clamping groove for fixing the copper part assembly is formed around the light-transmission through hole and formed in one side, facing the LD positioning lighting base, of the copper part assembly fixing block. According to the LD focusing jig of the 3D imaging module for minitype biological intelligent structural light disclosed by the invention, a product can be quickly focused and assembled, so that the efficiency is improved, and poor products caused by eccentricity is reduced.
Description
technical field [0001] The invention relates to a laser diode (LD) focusing jig for a miniature biological intelligent structured light 3D image module, and belongs to the technical field of manufacturing a micro biological intelligent structured light 3D image camera module. Background technique [0002] The laser light is emitted from the laser and then converged into a narrow band of light through the lens, which is called structured light. Structured light is a mainstream technology of depth cameras, which can be used in multiple application scenarios such as human-computer interaction, intelligent biometric identification, 3D modeling, AR, security and assisted driving. At present, during the processing of micro-biological intelligent structured light modules (with a size below 5.0mm×5.0mm×4.7mm), especially when the laser diode and the lens are focused, it is easy to cause the collimated spot to become larger or smaller, resulting in focusing Blurring affects the imag...
