Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0055] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0056] As described above, in the traditional laser test experiment, due to the complex operation of the existing test instruments, it is easy to cause damage to the pins of the laser to be tested.

[0057] To at least partially solve one or more of the above problems and other potential problems, exemplary embodiments of the present utility model provide a tool for laser testing, including: a mounting platform 1; a rotating platform 2 rotatably disposed on the surface of the mounting platform 1; a rotating drive assembly 3 disposed on the inner top surface of the mounting platform 1, with the driving part connected to the rotating platform 2; a laser mounting platform 4 disposed above the rotating drive assembly 3, and several lasers to be tested 10 are provided inside the laser mounting platform 4; a test circuit board 5 disposed between the laser mounting platform 4 and the rotating platform 2; a laser receiving device 6 disposed on one side of the rotating platform 2; an automatic loading platform 7 disposed on the other side of the rotating platform 2, and the loading end of the automatic loading platform 7 is arranged close to the laser mounting platform 4; and a support assembly 8, with one end connected to the surface of the rotating platform 2 and the other end passing through the test circuit board 5 and connected to the laser mounting platform 4.

[0058] In the above embodiment, during the test preparation stage, the lasers to be tested 10 are loaded into the automatic loading platform 7, and the rotating drive assembly 3 is started, so that the rotating drive assembly 3 drives the rotating platform 2 to rotate on the surface of the mounting platform 1. Since the laser mounting platform 4 and the test circuit board 5 are both mounted on the surface of the rotating platform 2 through the support assembly 8, when the rotating platform 2 rotates, it drives the laser mounting platform 4 to rotate on one side of the automatic loading platform 7. During this process, the automatic loading platform 7 continuously puts the lasers to be tested 10 into the laser mounting platform 4, so that the lasers to be tested 10 are arranged in a divergent manner with the center of the laser mounting platform 4 as the center. Press down the laser mounting platform 4, so that the laser mounting platform 4 and the test circuit board 5 approach the rotating platform 2 along the support assembly 8. During the approaching process, the test circuit board 5 is electrically connected to the pins of the lasers to be tested 10;

[0059] During the test stage, when the pins of the lasers to be tested 10 are electrically connected to the test circuit board 5, the lasers to be tested 10 are powered on to emit laser light. The rotating drive assembly 3 is started again, so that the rotating drive assembly 3 drives the rotating platform 2 to rotate. When the lasers to be tested 10 on the laser mounting platform 4 rotate, the lasers to be tested 10 make circular motions around the center of the laser mounting platform 4, so that the laser light released by each laser to be tested 10 is sequentially received by the laser receiving device 6, thereby detecting the laser intensity released by each laser to be tested 10 through the laser receiving device 6;

[0060] After the test is completed, lift the laser mounting platform 4, so that the pins of the lasers that have completed the test on the laser mounting platform 4 are disconnected from the test circuit board 5, remove the lasers that have completed the test, and reload the lasers to be tested 10 for the next test;

[0061] High-efficiency batch testing capability. Through the divergent layout design of the rotating platform 2 and the lasers 10 to be tested, multiple lasers 10 to be tested can be accommodated at a time. The linkage between the automatic loading platform 7 and the rotation drive assembly 3 realizes the assembly line operation of testing and replacement, improving the testing efficiency.

[0062] The circular motion trajectory ensures equal-distance and equal-angle testing of each laser with the receiving device.

[0063] It improves the problems existing in traditional laser testing, such as low efficiency, poor consistency, and difficulty in dynamic testing. It is particularly suitable for full-parameter detection (light intensity, wavelength, divergence angle, etc.) in the batch production scenario, and is applicable to fields such as optical communication devices and lidar components.

[0064] Please refer to Figures 1-9 As shown in, in some embodiments, the rotating platform 2 includes: a first circular plate 21, spaced on the surface of the installation platform 1; a limiting ring 22, spaced on the bottom surface of the first circular plate 21; a plurality of support rods 23, provided between the surface of the limiting ring 22 and the bottom surface of the first circular plate 21; a plurality of limiting blocks 24, arranged in an annular array between the limiting ring 22 and the installation platform 1; a limiting groove 25, provided on the top surface of each limiting block 24; wherein the bottom ends of the limiting blocks 24 are arranged on the surface of the installation platform 1, and the outer circumferential wall of the limiting ring 22 slides in each limiting groove 25.

[0065] In the above embodiments, the output shaft of the rotation drive assembly 3 is connected to the center of the bottom surface of the first circular plate 21. When the output end of the rotation drive assembly 3 works, it drives the first circular plate 21 to rotate on the surface of the installation platform 1. During rotation, the limiting ring 22 on the bottom surface of the first circular plate 21 slides in the limiting grooves 25 on the surfaces of the limiting blocks 24. The limiting blocks 24 are arranged in an annular array below the limiting ring 22, providing good support for the limiting ring 22 and preventing the first circular plate 21 from shaking during rotation.

[0066] Please refer to Figures 1-9 As shown in, in some embodiments, the rotation drive assembly 3 includes: a first motor 31, installed on the inner top surface of the installation platform 1, and the output shaft passes through the surface of the installation platform 1; a driving gear 32, arranged on the surface of the installation platform 1, connected to the output shaft of the first motor 31; a transmission gear 33, arranged on the surface of the installation platform 1, meshing with one side of the driving gear 32; a tooth ring 34, arranged on the bottom surface of the first circular plate 21, concentric with the driving gear 32; wherein the inner wall of the tooth ring 34 meshes with the transmission gear 33.

[0067] In the above embodiments, when it is necessary to drive the first circular plate 21 to rotate, the output shaft of the first motor 31 rotates, driving the driving gear 32 to rotate around the output shaft of the first motor 31. When the driving gear 32 rotates, it drives the transmission gear 33 meshing with it to rotate. The transmission gear 33 is rotatably arranged on the surface of the mounting platform 1. When the driven gear rotates, it drives the tooth ring 34 meshing with it to rotate around the center of the driving gear 32. Since the top surface of the tooth ring 34 is fixedly connected to the bottom surface of the first circular plate 21 and the center of the tooth ring 34 coincides with the center of the bottom surface of the first circular plate 21, during the rotation of the first circular plate 21 and the tooth ring 34, the limiting ring 22 slides in the limiting groove 25, and the limiting groove 25 limits the rotation of the limiting ring 22 and the first circular plate 21.

[0068] Please refer to Figures 1-9 , in some embodiments, the laser mounting platform 4 includes: a laser carrying platform 41, arranged above the test circuit board 5; a laser cover plate 42, spaced apart from the surface of the laser carrying platform 41; a plurality of first arc-shaped grooves 43, which are arranged in a circular array on the surface of the laser carrying platform 41; a plurality of second arc-shaped grooves 44, which are arranged in a circular array on the bottom surface of the laser cover plate 42; wherein the first arc-shaped grooves 43 and the second arc-shaped grooves 44 are arranged in one-to-one correspondence, and the laser to be tested 10 is installed between the first arc-shaped groove 43 and the second arc-shaped groove 44.

[0069] In the above embodiments, the laser to be tested 10 is installed between the first arc-shaped groove 43 and the second arc-shaped groove 44. The automatic loading platform 7 pushes the laser to be tested 10 into the first arc-shaped groove 43 on the surface of the laser carrying platform 41. Subsequently, when the laser cover plate 42 is pressed, the second arc-shaped groove 44 on the surface of the laser cover plate 42 fixes the surface of the laser to be tested 10, preventing the laser to be tested 10 from being detached from the surface of the laser carrying platform 41 under the influence of centrifugal force when the laser to be tested 10 rotates around the center of the rotating platform 2. One end of the first arc-shaped groove 43 and the second arc-shaped groove 44 close to the outer wall of the circumference of the laser carrying platform 41 is open, so that when the laser to be tested 10 emits laser light, the laser light can be emitted from the openings of the first arc-shaped groove 43 and the second arc-shaped groove 44 to the laser receiving device 6.

[0070] Please refer to Figures 1-9 , in some embodiments, the test circuit board 5 includes: a circuit board body 51, arranged between the laser carrying platform 41 and the rotating platform 2; a plurality of test probes 52, which are arranged in a circular array on the surface of the circuit board body 51; wherein one end of the test probe 52 is electrically connected to the circuit board body 51.

[0071] In the above embodiments, the circuit board body 51 is disposed between the laser carrier platform 41 and the rotating platform 2. When the laser carrier platform 41 drives the laser under test 10 to move downward, the test probe 52 passes through the laser carrier platform 41 and contacts the pins of the laser under test 10 in the first arc-shaped groove 43, so that the circuit board body 51 is electrically connected to each laser under test 10. After the laser under test 10 is powered on, it emits laser light.

[0072] Please refer to Figures 1-9 , in some embodiments, the support assembly 8 includes: a plurality of slide bars 81, the bottoms of the plurality of slide bars 81 are mounted on the surface of the first circular plate 21, and the tops respectively pass through the circuit board body 51, the laser carrier platform 41 and are connected to the laser cover plate 42; wherein each of the slide bars 81 is arranged in a ring on the surface of the first circular plate 21; a plurality of first springs 82, each of the first springs 82 is sleeved on the outer wall of the circumference of each slide bar 81; wherein the first springs 82 are respectively arranged between the first circular plate 21 and the circuit board body 51, between the circuit board body 51 and the laser carrier platform 41, and between the laser carrier platform 41 and the laser cover plate 42.

[0073] In the above embodiments, when the first circular plate 21 and the circuit board approach each other, the first spring 82 between them contracts, and the circuit board slides downward along the outer wall of the circumference of the slide bar 81. The laser carrier platform 41 compresses the first spring 82 and approaches the circuit board body 51, compressing the first spring 82 between them. The laser cover plate 42 approaches the laser carrier platform 41, compressing the first spring 82 between them. When it is necessary to reload the laser under test 10 after the test is completed, the first spring 82 increases the distance between the first circular plate 21 and the circuit board body 51, between the circuit board body 51 and the laser carrier platform 41, and between the laser carrier platform 41 and the laser cover plate 42, so that the test probe 52 is separated from the pins of the laser under test 10, avoiding damage caused by the collision between the pins of the laser under test 10 and the top of the test probe 52 when the laser under test 10 is pushed into the first arc-shaped groove 43 during the loading of the laser under test 10.

[0074] Please refer to Figures 1-9 , in some embodiments, a limiting assembly 9 is further provided between the rotating platform 2 and the test circuit board 5; a plurality of limiting assemblies 9 are arranged in a ring array on the surface of the rotating platform 2, and the limiting assembly 9 includes: a mounting foot 91, the bottom end of which is disposed on the surface of the first circular plate 21; a limiting rod 92, the bottom end of which is disposed on the top surface of the mounting foot 91; a plurality of limiting holes 93, which are arranged in a ring array on the surface of the circuit board body 51; wherein each of the limiting holes 93 corresponds to each of the limiting rods 92; a second spring 94 is sleeved on the outer wall of the circumference of the limiting rod 92.

[0075] In the above embodiments, when the circuit board body 51 moves downward, the limiting rod 92 passes through the limiting hole 93. When it continues to move downward, the bottom surface of the circuit board body 51 abuts against the top end of the second spring 94, causing the second spring 94 to be compressed. Until the second spring 94 can no longer be compressed, the surface of the circuit board body 51 is horizontally arranged on the surface of the rotating platform 2. Subsequently, when the circuit board body 51 moves downward, it is avoided that the surface of the circuit board body 51 cannot be horizontal finally, resulting in different heights of the top ends of the test probes 52 and unable to make effective electrical connection with the pins of the laser to be tested 10. It can also avoid the test probes 52 being compressed and broken due to excessive compression.

[0076] Please refer to Figures 1-9 , in some embodiments, the automatic loading platform 7 includes: a bracket 71, arranged on the surface of the laser cover plate 42 and spaced from the laser cover plate 42; wherein the bracket 71 is installed at the top ends of the sliding rods 81; an electric telescopic rod 72, arranged at the top end of the bracket 71; wherein the telescopic end of the electric telescopic rod 72 passes through the bracket 71 and is connected to the surface of the laser cover plate 42; a loading plate 73, arranged on the surface of the installation platform 1; a loading groove 74, arranged on the surface of the loading plate 73; wherein the length direction of the loading groove 74 is perpendicular to the outer wall of the circumference of the laser carrying platform 41, and the lasers to be tested 10 are arranged at intervals in the loading groove 74; a plurality of shifting rods 75, arranged between the lasers to be tested 10; a mounting rod 76, arranged on the surface of each shifting rod 75, and the shifting rods 75 are arranged at intervals on the bottom surface of the mounting rod 76; an L-shaped rod 761, one end of which is hinged to one end of the mounting rod 76; a first connecting rod 762, the top end of which is hinged to the corner of the L-shaped rod 761, and the bottom end of which is hinged to the surface of the loading plate 73; a horizontal rod 763, arranged on the upper part of the mounting rod 76, and one end of which is hinged to the end of the L-shaped rod 761 away from the mounting rod 76; a Y-shaped rod 764, the first end of which is hinged to the end of the horizontal rod 763 away from the L-shaped rod 761, and the second end of which is hinged to the end of the mounting rod 76 away from the L-shaped rod 761; a second connecting rod 765, the top end of which is hinged to the intersection of the Y-shaped rod 764, and the bottom end of which is hinged to the surface of the loading plate 73; a third connecting rod 766, one end of which is hinged to the third end of the Y-shaped rod 764; a second motor 767, the output shaft of which is connected to the end of the third connecting rod 766 away from the Y-shaped rod 764; a motor mounting rod 768, the bottom end of which is installed on the surface of the loading plate 73, and the top end of which installs the second motor 767; wherein the horizontal rod 763 is parallel to the mounting rod 76, and the first connecting rod 762 is parallel to the second connecting rod 765.

[0077] In the above embodiments, when loading the laser 10 to be measured, first place a plurality of lasers 10 to be measured in the loading groove 74, so that the lasers 10 to be measured are arranged at intervals in the loading groove 74. Start the second motor 767. The output shaft of the second motor 767 drives the third connecting rod 766 to make a circular motion around the output shaft of the second motor 767, and then drives the third end of the Y rod 764 to make a circular motion around the output shaft of the third motor, and then pulls the first end and the second end of the Y rod 764 to make an elliptical motion. The two ends of the L rod 761 make an elliptical motion. At the same time, the first end of the Y rod 764 and one end of the L rod 761 pull the mounting rod 76 to make an elliptical motion. When the mounting rod 76 is located in the lower half of the elliptical motion trajectory, the mounting rod 76 drives each shifting rod 75 to move downward, pushing the laser 10 to be measured to move in the direction of the first arc groove 43, and then lifting it. When the mounting rod 76 is located in the upper half of the elliptical motion trajectory, it drives the shifting rod 75 to move upward and reset, pushing each laser 10 to be measured into the first arc groove 43 in turn.
