Description
Technical Field
[0001] The present invention relates to the technical field of laser life detection, and in particular to a laser durability testing device and method. Background Art
[0002] A semiconductor laser is a light source that uses semiconductor materials (such as gallium arsenide and indium phosphide) as laser media and generates laser output through electric current drive. It is often used in communications, sensing, medical and other fields, and has the advantages of small size, high efficiency and long life. In appearance, semiconductor lasers are usually small rectangular or cylindrical, equipped with metal or plastic packaging to protect internal components, and with a light-emitting surface or optical fiber interface at the end of the package for outputting laser beams. The life detection of semiconductor lasers is the process of evaluating their performance and stability in actual use, aiming to determine how long the laser can continue to work under different working conditions.
[0003] In the prior art, when batch life tests are performed on semiconductor lasers, workers usually insert the semiconductor lasers into the power socket, wait for the test to be completed, unplug the semiconductor lasers, kick out the unqualified semiconductor lasers, and store them in designated locations. Workers are prone to fatigue from long-term laser plugging and unplugging and sorting work, which can lead to errors in the inspection process, especially in the sorting of qualified and unqualified products. Fatigue can reduce workers' concentration and operational accuracy, resulting in unqualified lasers being misclassified as qualified products, or vice versa, placing qualified products in unqualified areas. This inaccurate sorting not only affects product quality control and increases rework and testing costs, but can also cause unqualified products to enter the market, affecting the end-user experience and the reliability reputation of the product.

[0047] The specific implementation steps and principles of the present invention are as follows:
[0048] In the initial state, the auxiliary wheel 341 is at the top of the bottom horizontal surface 361, and the self-release door 33 opens the bottom of the storage box 22. At this time, the blocking microswitch 14 is not pressed, the blocking cylinder 16 is in an extended state, and the blocking plate 18 closes the top of the guide frame 19. When the entire device needs to work, the horizontal cylinder 27 is started, the horizontal cylinder 27 retracts, and the horizontal cylinder 27 drives the integrated structure of the storage box 22 to move upward.

[0050] After waiting for the laser life detection, the main controller 25 drives the second square slot 62 or the third square slot 63 on the multi-functional disc 6 to rotate to a position parallel to the storage box 22 according to the detection structure, and the horizontal cylinder 27 extends again. The auxiliary wheel 341 is at the top of the bottom horizontal surface 361, and the self-release door 33 opens the bottom of the storage box 22. At this time, the blocking microswitch 14 is not pressed, the blocking cylinder 16 is in an extended state, and the blocking plate 18 closes the top of the material guide frame 19, and the laser falls into the first storage box 11 or the second storage box 9.
