It is made of semiconductor materials and features miniaturization, high efficiency, and high precision. When testing a laser diode, simply connect the pins to make it emit light and observe its brightness. If the laser diode's light emission meets the preset requirements, it proves that the chip inside the laser diode meets the requirements; otherwise, the tested laser diode does not meet the requirements.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a power monitoring device for laser diode chips with a positioning mechanism, including a laser power detector 11 and a positioning mechanism. The positioning mechanism is used to position the laser diode, and the positioning mechanism corresponds to the laser power detector 11. Figure 2 and Figure 3 As shown, the positioning mechanism includes a support ring 8, with multiple support tubes 15 on one side of the support ring 8. Each support tube 15 is mounted on a U-shaped seat 17, and each U-shaped seat 17 is slidably mounted on the support ring 8. Annular grooves 25 are provided on both sides of the support ring 8, and a block is provided on the inner wall of the U-shaped seat 17 that is movable within the annular groove 25. This allows the U-shaped seat 17 to slide freely along the support ring 8 without falling off. When the U-shaped seat slides to a preset position, it needs to be positioned. Therefore, a first fastening knob 18 is threaded onto the side of the U-shaped seat 17, and the first fastening knob 18 passes through the U-shaped seat 17 and abuts against the support ring 8.

[0023] Each U-shaped seat 17 has a guide seat 16 on one side, and the support tube 15 is movably placed inside the guide seat 16. A second fastening knob 20 is threaded onto the guide seat 16, and the second fastening knob 20 passes through the guide seat 16 and abuts against the support tube 15. Therefore, the support tube 15 can rotate around the support ring 8 through the U-shaped seat 17, and the support tube 15 can also move within the guide seat 16. After the length of the support tube is adjusted, it can be positioned by the second fastening knob 20.

[0024] Each end of the support tube 15 near the center of the support ring 8 is provided with a conductive insert 13. The size of the conductive insert 13 matches the pin size of the laser diode, and the position of the conductive insert 13 corresponds to the position of the laser diode pin. In use, the pins of the laser diode to be tested are inserted into the conductive insert 13 respectively, and the laser diode can be fixed. Because the conductive insert 13 can change position with the movement of the support tube 15, the position of the conductive insert 13 can be adjusted to any position, so that the conductive insert 13 can meet the testing requirements of laser diodes of different sizes.

[0025] Each support tube 15 is connected to the conductive insertion tube 13, and each support tube 15 has a movable stop rod 24 inside. The end of the stop rod 24 away from the conductive insertion tube 13 is provided with a fastening mechanism, such as... Figure 4 As shown, the fastening mechanism includes a support sleeve 9 located at the end of the support tube 15 away from the conductive insertion tube 13, with internal threads inside the support sleeve 9; a drive rod 26 located at the end of the abutment rod 24 away from the conductive insertion tube 13, with external threads on its surface, and the drive rod 26 is threaded into the support sleeve 9. A knob 10 is located at the end of the drive rod 26. When the knob 10 is rotated, it can drive the drive rod 26 to rotate in and out of the support sleeve 9, thereby allowing the abutment rod 24 to freely extend and retract within the conductive insertion tube 13. That is, under the action of the fastening mechanism, one end of the abutment rod 24 extends into the conductive insertion tube 13, thereby clamping the pins located within the conductive insertion tube 13 and preventing the laser diode from falling out.

[0026] Furthermore, the support ring 8 is installed on the top of the support section, which includes a socket 5 on the side of the support ring 8. The socket 5 has a polygonal prism structure, and its bottom is movably inserted into the top of the adjusting column 21. That is, the top of the adjusting column 21 has a polygonal prism hole that matches the polygonal prism. In use, the adjusting column 21 is movably inserted into the fixing tube 3. The top of the fixing tube 3 is threaded with a third fastening knob 22. The bolt at the end of the third fastening knob 22 passes through the fixing tube 3 and abuts against the adjusting column 21, which is used to position the adjusting column 21. The bottom of the fixing tube 3 is connected to the support plate 23. When the support ring 8 is pulled out from the top of the adjusting column 21, the support ring 8 can be laid flat for easy wiring of the laser diode.

[0027] like Figure 1As shown, the probe head and support plate 23 of the laser power detector 11 are both mounted on the slide rail 4 via sliders 2, and the slide rail 4 is mounted on the strip seat 1. The two ends of the strip seat 1 are perpendicularly connected to the strip plate 6, and each slider 2 is threaded with a fourth fastening knob 19. The bolt at the end of the fourth fastening knob 19 passes through the slider 2 and abuts against the strip seat 1. The strip seat 1 and the strip plate 6 form an "I"-shaped frame, which is supported in a plane.

[0028] Furthermore, each end of the fixed tube 3 is provided with a connecting foot 14, and a wire is connected to the connecting foot 14. The connecting foot 14 is connected to the laser power regulator 7 through the wire 12, and the laser power regulator is connected to the laser power supply (mains power) through the wire. The connection between the connecting foot 14 and the wire can be sealed with heat shrink tubing, and the conductive tube 13 has an insulating layer on the outside, such as a rubber layer, but the inner surface of the conductive tube 13 is exposed. In this way, even if the conductive tubes 13 touch each other when adjusting the position of the conductive tubes 13, there is no possibility of electric shock.

[0029] Based on the above embodiments, the specific monitoring process is as follows: First, insert the pins of the laser diode to be tested into the corresponding conductive tube 13, then fix each pin by turning the knob 10 to drive the stop rod, and then control the laser power regulator 7 to supply power to the laser diode. Secondly, place the laser diode and the probe of the laser power detector 11 on the same straight line, and let the light emitted by the laser diode shine on the probe of the laser power detector 11. At this time, the power of the laser diode can be monitored. The output power of the laser diode can be adjusted by the laser power regulator 7. In this way, it can be observed whether the light emitted by the laser diode under different power outputs meets the preset requirements. If the preset requirements are met, it can be proven that the laser diode chip meets the requirements. Finally, after one laser diode has been tested, the other laser diode can be connected into the conductive tube 13. The operation is simple and convenient. Moreover, the support ring 8 and the probe of the laser power detector can be adjusted in position via the slide rail, thereby adjusting the distance between the laser diode and the laser power detector 11 to achieve the optimal distance.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
