Embodiments of the invention relate to the technical field of semiconductor lasers, and disclose a lens coupling positioning device and a coupling positioning method thereof; the lens coupling and positioning device comprises a base, a base adjusting mechanism, a chuck, a chuck adjusting mechanism and a visual image detection mechanism; the base used for placing a plurality of chips is arranged onthe base adjusting mechanism, and the base adjusting mechanism is used for moving the chip to be coupled to an observation area; the chuck used for clamping the lens is connected to the output end ofthe chuck adjusting mechanism, and the input end of the chuck adjusting mechanism is connected to the visual image detection mechanism; and the lens of the visual image detection mechanism faces thebase so as to measure the relative positions of the lens and the chip to be coupled. According to the lens coupling positioning device, the chuck adjusting mechanism, the base adjusting mechanism andthe visual image detection mechanism are matched with each other, so that the automatic and continuous operation of sequentially carrying out lens coupling positioning on the plurality of chips can becompleted, and the precision and the efficiency of the coupling process are improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of semiconductor lasers, in particular to a lens coupling positioning device and a coupling positioning method thereof. Background technique [0002] Semiconductor lasers are P-N junction diodes with optical feedback functions that use semiconductor materials as the working substance. Compared with solid-state lasers and gas lasers, they have the advantages of compact structure, high reliability, high efficiency and stability, and have been widely used in mechanical processing, materials, etc. industries such as processing, weapons manufacturing and laser display. Semiconductor lasers have special light-emitting characteristics, and the output laser light generally cannot be directly used in practice, and must be shaped, transformed and collimated. Therefore, since the birth of semiconductor lasers, the coupling problem of semiconductor lasers has arisen. The so-called coupling proces...
