[0017] Beneficial effects
[0018] This invention provides a laser pulse testing fixture. Compared with the prior art, it has the following advantages:
[0019] 1. This laser pulse testing fixture secures multiple laser emitters with different power ranges to a mounting plate using protective housings and reinforcing nuts. Then, the second servo motor is activated, driving the worm gear to rotate. The worm gear then drives the worm wheel, which in turn drives the movable plate to rotate. The movable plate then drives the beam analyzer to rotate synchronously, aligning it with the laser emitter of the required power. This eliminates the time required to change between laser emitters of different power, thus improving testing efficiency.
[0020] 2. This laser pulse testing fixture starts the first servo motor, which drives the lead screw to rotate. Because the nut block is limited by the limit rod, the nut block will move linearly along the lead screw when the lead screw rotates. At the same time, the nut block will also drive the support to move, thereby adjusting the distance between the laser emitter and the beam analyzer to obtain different test data. The grooves on the roller are used to fix the cables connected to the laser emitter to prevent them from getting tangled together. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] Reference Figures 1 to 5This application provides a laser pulse testing fixture, including a base plate 1, with an adjustment testing component 2 disposed on the top of the base plate 1; the adjustment testing component 2 includes a support column 21, which is fixedly connected to the top of the base plate 1, and a mounting plate 22 is fixedly connected to one side of the support column 21; the adjustment testing component 2 also includes a protective shell 23, with a laser emitter 24 fixedly installed inside the protective shell 23, and the protective shell 23 is movably connected to the interior of the mounting plate 22; the adjustment testing component 2 also includes a nut block 29, with a support 211 fixedly installed on the top of the nut block 29, and a movable disk 212 rotatably connected inside the support 211; a beam analyzer 213 is fixedly installed on one side of the movable disk 212, and a worm gear 214 is fixedly connected to the other side of the movable disk 212. A protrusion 219 is fixedly connected to the top of the nut block 29, and a worm gear 221 is rotatably connected between the two protrusions 219. The worm gear 221 meshes with a worm wheel 214. A second servo motor 220 is fixedly mounted on the top of the nut block 29, and the output shaft of the second servo motor 220 is fixedly connected to one end of the worm gear 221. A roller 210 is fixedly mounted on the bottom of the nut block 29, and the roller 210 makes rolling contact with the top of the base plate 1. The adjustment test assembly 2 also includes a reinforcing nut 25, which is threadedly connected to the mounting plate 22 and the interior of the protective shell 23.
[0031] In practice: Multiple laser emitters 24 with different power ranges are fixed together on the mounting plate 22 by the cooperation of the protective shell 23 and the reinforcing nut 25. Then, the second servo motor 220 can be started to drive the worm gear 221 to rotate. The worm gear 221 drives the worm wheel 214 to rotate. The worm wheel 214 drives the movable plate 212 to rotate. The movable plate 212 can drive the beam analyzer 213 to rotate synchronously so that it is aligned with the laser emitter 24 with the required power. This can save the time of changing between laser emitters 24 with different power and thus improve the testing efficiency.
[0032] Reference Figures 1 to 5 In one aspect of this embodiment, a mating plate 26 is fixedly connected to the top of the base plate 1, and a lead screw 27 is rotatably connected between the two mating plates 26. The lead screw 27 is internally threadedly connected to the nut block 29. A limiting rod 28 is also fixedly connected between the two mating plates 26, passing through the nut block 29 and movably connected thereto. A first servo motor 215 is fixedly mounted on the top of the base plate 1, and the output shaft of the first servo motor 215 is fixedly connected to one end of the lead screw 27. An auxiliary rod 216 is fixedly connected to the top of the base plate 1, and a circular roller 217 is fixedly connected between the two auxiliary rods 216. A groove 218 is fixedly connected to the outer wall of the circular roller 217.
[0033] In specific implementation: by starting the first servo motor 215, the lead screw 27 is driven to rotate. Since the nut block 29 is restricted by the limit rod 28, the nut block 29 will move linearly along the lead screw 27 when the lead screw 27 rotates. At the same time, the nut block 29 will also drive the support 211 to move, thereby adjusting the distance between the laser emitter 24 and the beam analyzer 213 to obtain different test data. The groove 218 on the roller 217 is used to fix the cables connected to the laser emitter 24 respectively, which can effectively prevent them from getting tangled together.
[0034] All electrical devices in this plan are powered by an external power source.
[0035] Working principle: Before conducting laser pulse testing, multiple laser emitters 24 with different power ranges are installed in their respective protective shells 23. The protective shells 23 are then inserted into the mounting plate 22 through a movable connection between the protective shells 23 and the mounting plate 22. Finally, the reinforcing nuts 25 are connected to the internal threads of the mounting plate 22 and the protective shells 23, thereby fixing the laser emitters 24 onto the mounting plate 22 and completing the installation and fixing of the laser emitters 24 before testing.
[0036] During testing, when testing is required for laser emitters 24 with different power levels, the second servo motor 220 is activated. Its output shaft drives the worm gear 221 to rotate between the two protrusions 219. Since the worm gear 221 meshes with the worm wheel 214, the rotation of the worm gear 221 drives the worm wheel 214 to rotate. The worm wheel 214 then drives the movable disk 212 to rotate within the support 211. The movable disk 212 drives the beam analyzer 213 to rotate synchronously, thereby aligning the beam analyzer 213 with the laser emitter 24 of the required power. This eliminates the time required to change between laser emitters 24 with different power levels and improves testing efficiency.
[0037] If it is necessary to adjust the distance between the laser emitter 24 and the beam analyzer 213 to obtain different test data, the first servo motor 215 is started, and its output shaft drives the lead screw 27 to rotate between the two docking plates 26. Since the lead screw 27 is internally threaded with the nut block 29, and the nut block 29 is limited by the through-hole limit rod 28, when the lead screw 27 rotates, the nut block 29 will move linearly along the lead screw 27 and the limit rod 28. At the same time, the roller 210 at the bottom of the nut block 29 rolls on the top of the base plate 1 to assist the movement of the nut block 29. The movement of the nut block 29 will drive the support 211 and the beam analyzer 213 above to move synchronously, thereby realizing the adjustment of the distance between the laser emitter 24 and the beam analyzer 213.
[0038] In addition, the cables connected to the laser emitter 24 can be fixed in the grooves 218 on the outer wall of the roller 217. The separation and arrangement of the grooves 218 can effectively prevent the cables from getting tangled together and ensure the orderly conduct of the test process.
