Problems solved by technology

The processing of traditional cylindrical single production biometric lens modules mostly adopts sheet biometric lens modules to cut out a single production biometric lens module and then undergo rounding, gluing and UV curing processes, which need to be bonded once during the gluing process Alignment once, most of this kind of process has low efficiency, the appearance yield rate is repaired, and the dimensional accuracy of the processed product is low, which cannot meet customer needs

Embodiment Construction

[0024] refer to figure 1 , figure 2 , image 3 with Figure 4 , the processing technology of a kind of multi-layer laminated biometric lens module of the present invention, comprises the following several steps:

[0025] The first step is to superimpose the biometric lens module, and align and stack three layers of the same sheet-shaped biometric lens module;

[0026] The second step is to attach the protective glass, and attach the protective glass to the upper end of the uppermost sheet biometric lens module and the lower end of the lowermost sheet biometric lens module with glue;

[0027] The third step is metal blade cutting. Place the multi-layer sheet biometric lens module after bonding the protective glass in the second step on the backing plate with cutting grooves to carry out the separation between the multi-layer sheet biometric lens module and the cutting groove. Align the CCD between them and use a Disco metal blade to cut the multi-layer sheet biometric lens...

Abstract

The invention discloses a processing technology of a multilayer superimposed biological recognition lens module. The processing technology comprises the following steps of step 1, superimposition of the biological recognition lens module; step 2, pasting of protective glass; step 3, cutting of a metal blade; step 4, cylindrical processing of the single multilayer biological recognition lens module; step 5, degumming processing; and step 6, ultrasonic cleaning. The processing technology of the multilayer superimposed biological recognition lens module has the advantages that the processing precision is high, the non-defective product rate of the appearance is high, and the technology is novel.

Description

【Technical field】 [0001] The invention relates to the technical field of biometric lens module processing, in particular to the technical field of a multilayer laminated biometric lens module processing technology. 【Background technique】 [0002] The center of the cylindrical biometric lens module has a light hole, which is often used as an optical component. The biometric lens module is also equipped with multi-layer optical coating and metal film to achieve good light transmission effect. The processing of traditional cylindrical single production biometric lens modules mostly adopts sheet biometric lens modules to cut out a single production biometric lens module and then undergo rounding, gluing and UV curing processes, which need to be bonded once during the gluing process For one alignment, most of this process has low efficiency, the appearance yield rate is repaired, and the dimensional accuracy of the processed product is low, which cannot meet customer needs.
