Problems solved by technology

Since the fast-axis collimating lens is pre-stored in the tray, the position accuracy of loading it into the tray may not be guaranteed, so the picking up of the lens will also cause inaccurate positioning, resulting in a decrease in coupling accuracy or even coupling failure. , which needs to be improved

Embodiment 1

[0037] Embodiment 1 of the present invention provides a collimating lens automatic coupling packaging method, which specifically includes the following steps:

[0038] S1. After the lens is loaded and positioned in the tray according to the preset attitude, the lens fixture moves to the pick-up point of the tray to pick up the lens, and then moves to the inspection point. Among them, the lens fixture has multiple high-precision displacement degrees of freedom, which can not only move the lens from the tray to the coupling packaging position, but also fine-tune each corresponding position to adjust the picking posture or lens coupling posture. Due to high coupling accuracy requirements, there is a certain deviation in the placement position of the lens in the tray, which may cause deviations in picking and positioning and reduce coupling accuracy. Therefore, the lens fixture and lens move to the inspection point to confirm the picking and positioning accuracy.

Abstract

The invention relates to the technical field of lens coupling, in particular to an automatic coupling and packaging method for collimating lenses. The automatic coupling packaging method comprises the following steps that 1, the lenses are picked up and moved to detection points; 2, the detection points are visually detected in the X direction, the Y direction and the Z direction through the reflection effect, and the lens pickup positioning deviation is confirmed; 3, the pick-up positioning deviation of the lenses is corrected; 4, the lenses are moved to the coupling positions to complete coupling; and 5, the lenses are dispensed and cured. According to the automatic coupling and packaging method, after the lenses are picked up, the pick-up precision is confirmed in a visual positioning manner, the datum point deviation of the lenses relative to the chuck is confirmed from multiple directions through the reflection effect, if the pick-up precision does not meet the requirement, the lenses are placed at the transfer position, the lenses are picked up for the second time after the pick-up posture is adjusted, and the relative positions of the lenses are corrected, so that the accuracy of lens picking and positioning is ensured, and the coupling and packaging precision of the lenses is improved.

Description

technical field [0001] The invention relates to the technical field of lens coupling, in particular to an automatic coupling packaging method for a collimating lens. Background technique [0002] Semiconductor lasers have the characteristics of small size, light weight, high efficiency, and long life. They can be pumped by simply injecting current. Their operating voltage and current are compatible with integrated circuits, so they can be monolithically integrated with them. Direct current modulation with frequencies up to GHz for high-speed modulated laser output. Due to these advantages, semiconductor lasers have been widely used in laser communication, optical storage, optical gyroscope, laser printing, ranging and radar. [0003] With the development of practical engineering, the output power requirements of semiconductor lasers are getting higher and higher. Semiconductor lasers usually have a fast-axis collimating lens (FAC). In order to ensure the output power, the ...
