Abstract

The invention relates to an optical fingerprint identification module detection device, comprising a base, a moving base provided with a transverse fixing plate and slidably connected with the base through a longitudinal linear guide rail, a longitudinal driving device, a plurality of optical detection devices arranged transversely in parallel, and a detection circuit board arranged at the lower end of the base. Each optical detection device comprises a light source drive plate arranged at that front end of the transverse fix plate, a vertical linear guide rail connected with a rear end of a transverse fixing plate by a slider, a lifting seat connected with an upper end of the vertical linear guide rail, a lifting driving device, a cushioning floating assembly provided at a lower end of the vertical linear guide rail, an optical detection assembly provided at a lower end of the cushioning floating assembly, and a module detection seat provided on a base and positioned below the opticaldetection assembly. The optical fingerprint identification module detection device detects the photosensitivity and the resolution of the optical fingerprint identification module, and has high detection efficiency and small detection error.

Description

technical field [0001] The invention relates to the technical field of fingerprint module detection and sorting, in particular to an optical fingerprint recognition module detection device and detection method. Background technique [0002] Nowadays, fingerprint recognition technology has been widely used in smart phones, attendance machines, security access control and port customs clearance; testing the photosensitive performance and resolution of optical fingerprint recognition modules can ensure the reliability of optical fingerprint recognition modules ;The photosensitivity and resolution detection of the traditional optical fingerprint identification module is manually detected, which has the disadvantages of low detection efficiency and large detection error; therefore, an optical fingerprint with high detection efficiency and small detection error is designed Identifying the module detection device and detection method has become an urgent problem to be solved. Con...
