DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and other obvious variations can be envisioned by those skilled in the art.

[0024] like Figures 1 to 9 A detection and positioning device for a semiconductor laser is shown, comprising: A machine base 1, the top of which is rotatably connected to a testing platform 2, and a rotation driving mechanism is provided inside the machine base 1 for driving the testing platform 2 to rotate; An optical power meter probe 27 is provided at the detection position of the outer wall of the base 1 for receiving and detecting the optical power of the laser body 28; A plurality of slots 201 are provided in a circular array on the top surface of the testing platform 2, and two L-shaped clamping plates 5 are symmetrically and slidably connected in the plurality of slots 201; A first push adjustment mechanism matched with the number of the slots 201, the first push adjustment mechanism cooperates with the rotation drive mechanism to drive the two L-shaped clamping plates 5 corresponding to the detection position to clamp the laser body 28; The power connectors 4 are matched with the number of the slots 201, and the power connectors 4 are respectively arranged in the corresponding slots 201 through the clamping and conveying mechanism, and the clamping and conveying mechanism cooperates with the first pushing and adjusting mechanism to drive the power connector 4 at the detection position to be plugged with the laser body 28; In the prior art, during the laser detection and positioning process, the single-station operation mode requires frequent start-stopping of the equipment to replace samples, and when replacing samples, the power connector needs to be manually plugged in and out, which increases the detection cycle and reduces the detection efficiency. It is not convenient to detect lasers in large quantities. This technical solution can solve the above problems. The specific operations are as follows: Place multiple laser bodies 28 to be tested in the slot 201, with the bottom surface of the laser body 28 in contact with the top surface of the L-shaped clamping plate 5, and then start the rotation drive mechanism to rotate the test platform 2. The rotation of the test platform 2 will drive the multiple laser bodies 28 to rotate, and the multiple laser bodies 28 pass through the test position in turn to complete the test; In the process of rotating the detection table 2 to drive the laser body 28 to move to the detection position, the first push adjustment mechanism at the corresponding position drives the two L-shaped clamping plates 5 corresponding to the detection position to make the two L-shaped clamping plates 5 approach each other, adjust the position of the laser body 28 and clamp the laser body 28. This can improve the coincidence degree between the center of the light spot and the receiving surface of the optical power meter probe 27 and improve the detection accuracy. On the other hand, it can improve the stability of the laser body 28 during the detection process, preparing for the subsequent insertion of the power connector 4. After the two L-shaped clamping plates 5 adjust the position of the laser body 28 and clamp it, the power connector 4 at the detection position is driven to move through the clamping and conveying mechanism, so that the power connector 4 and the laser body 28 are plugged together, thereby starting the laser body 28, and the light outlet of the laser body 28 emits a laser signal to the optical power meter probe 27; After the detection is completed, the detection table 2 is driven to rotate by the rotation drive mechanism, so that the laser body 28 leaves the detection position (the laser body 28 at the next position moves to the detection position, and is positioned and detected according to the above operations). During the process of the laser body 28 leaving the detection position, first, the clamping and conveying mechanism drives the power connector 4 at the detection position to move, so that the power connector 4 is separated from the laser body 28. The laser body 28 is turned off, and the light output port stops emitting laser signals (at this time, the two L-shaped clamping plates 5 continue to clamp the laser body 28 to ensure the stability of the laser body 28 during the process of pulling out the power connector 4). After the power connector 4 is separated from the laser body 28, the first pushing and adjusting mechanism is used to drive the two L-shaped clamping plates 5 to move away from each other, releasing the clamping of the laser body 28, thereby facilitating the rapid replacement of a new detection sample and improving the detection efficiency.

[0025] As a further embodiment of the present invention, it further includes a power supply box 3. The power supply box 3 is fixedly connected to the top end of the detection table 2, and the power cord of the power connector 4 is connected to the power supply box 3; the power supply box 3 supplies power to the power connector 4.

According to the heating rate and temperature peak value of the laser body 28, it is beneficial to detect whether the heat dissipation of the laser body 28 is good.

[0027] As a further embodiment of the present invention, the rotation drive mechanism includes an annular rack 24. The annular rack 24 is fixedly connected to the bottom end of the detection table 2. A self-locking motor 25 is fixedly connected inside the machine base 1, and the output shaft of the self-locking motor 25 is fixedly connected with a transmission gear 26. The transmission gear 26 meshes with the annular rack 24; by starting the self-locking motor 25, the transmission gear 26 is driven to rotate. Under the meshing action, the annular rack 24 rotates, thereby driving the detection table 2 to rotate, and realizing the transportation of the laser body 28 to the detection position.

[0028] As a further embodiment of the present invention, it further includes several mounting plates 21. The several mounting plates 21 are respectively fixedly connected to the end of the notch 201. A reading head 22 is fixedly connected to the bottom end of the mounting plate 21, and an annular magnetic grating ruler 23 is fixedly connected to the top end of the machine base 1; by setting the reading head 22 and the annular magnetic grating ruler 23, detection points are set on the annular magnetic grating ruler 23. When the reading head 22 at the corresponding position detects the position information of the detection point, the self-locking motor 25 is turned off through an external controller to ensure that the laser body 28 accurately moves to the detection position, improve the coincidence degree between the center of the light spot and the receiving surface of the optical power meter probe 27, and reduce the detection error.

[0029] As a further embodiment of the present invention, it further includes a guide rail 17, the guide rail 17 is fixedly connected to the machine base 1, a slider 19 is driven in the guide rail 17 through a lead screw 18 (the lead screw 18 is rotatably installed in the guide rail 17, and the slider 19 is threadedly sleeved on the lead screw 18), an optical power meter probe 27 is fixedly connected to the top end of the slider 19, and a knob 20 is fixedly connected to the end of the lead screw 18; during the detection process, by rotating the knob 20, the lead screw 18 can be rotated, and in cooperation with the scale indication on the guide rail 17, the position of the optical power meter probe 27 can be flexibly adjusted according to the detection requirements, and the distance between the optical power meter probe 27 and the light outlet can be adjusted, thereby effectively preventing the ablation phenomenon of the optical power meter probe 27 caused by high energy density.

[0030] It should be noted that the optical power meter probe 27 is fixed to the top end of the slider 19 by bolts, and multiple groups of threaded holes are provided at the top end of the slider 19 to facilitate adjusting the position of the optical power meter probe 27, ensuring that the laser body 28 accurately moves to the detection position and improving the coincidence degree between the light spot center and the receiving surface of the optical power meter probe 27.

[0031] As a further embodiment of the present invention, it further includes: Two flipping clamping plates 14, the two flipping clamping plates 14 are symmetrically and rotatably connected to both ends of the L-shaped clamping plate 5; Two driving gears 15, the two driving gears 15 are symmetrically and rotatably connected to both ends of the L-shaped clamping plate 5, and the driving gear 15 is coaxially fixed to the corresponding flipping clamping plate 14; Two driving racks 16, the two driving racks 16 are engaged with the driving gears 15, and the driving racks 16 are fixedly connected in the notch 201; Specifically, by providing the flipping clamping plates 14, the driving gears 15 and the driving racks 16, during the process of the two L-shaped clamping plates 5 approaching each other, the driving gear 15 will move relative to the driving rack 16. Under the meshing action, the driving gear 15 rotates, thereby flipping the flipping clamping plate 14 to clamp the front and rear ends of the laser body 28, further adjusting the position of the laser body 28. On the one hand, during the detection process, the light outlet of each laser body 28 is kept at the same distance from the optical power meter probe 27 to improve the detection accuracy. On the other hand, it ensures that the distance between the power connector 4 and the interface on the laser body 28 is the same, which is beneficial for accurately connecting the power connector 4 to the interface on the laser body 28 and avoiding problems such as over-insertion or incomplete insertion of the power connector 4 into the interface.

[0032] As a further embodiment of the present invention, the first pushing and adjusting mechanism includes: two driving plates 7, the two driving plates 7 are respectively fixedly connected to the side walls of the two L-shaped clamping plates 5, and a driving groove 701 is provided at the top of the driving plate 7; Two driving rods 8 are symmetrically slidably connected in the notch 201 , and a push pin 801 is fixed at the end of the driving rod 8 , and the push pin 801 is slidably connected in the driving slot 701 at the corresponding position.

[0033] Push the adjustment component, and push the adjustment component to cooperate with the rotation drive mechanism. When the laser body 28 rotates to the position of the optical power meter probe 27, push the adjustment component to drive the two driving rods 8 at the target position to extend. Under the guidance of the driving groove 701, the two L-shaped clamping plates 5 are close to each other. The push adjustment assembly includes: a column 9, the bottom end of which is fixedly connected to the base 1; An annular driving frame 10, the annular driving frame 10 is fixedly connected to the top of the column 9, and the annular driving frame 10 is rotatably connected to the bottom end of the detection platform 2; An upper track groove 1001 and a lower track groove 1002 are respectively provided on the upper bottom surface and the lower bottom surface of the annular driving frame 10; The upper track groove 1001 and the lower track groove 1002 both have an arc groove 1003, both ends of the arc groove 1003 are connected to guide grooves 1004, the ends of the two guide grooves 1004 are connected to each other, and the connection point of the ends of the two guide grooves 1004 is located at the position of the optical power meter probe 27; Two sliding pins 802, the two sliding pins 802 are respectively fixedly connected to the ends of the driving rod 8, and the sliding pins 802 at corresponding positions are respectively slidably connected in the upper track groove 1001 and the lower track groove 1002; Specifically, during the rotation of the detection table 2, the two sliding pins 802 at the corresponding positions will move along the upper track groove 1001 and the lower track groove 1002 respectively. When the laser body 28 has not moved to the detection station, the two sliding pins 802 are located in the arc groove 1003. During the movement of the laser body 28 to the detection station, the sliding pin 802 first moves along the arc groove 1003, and then moves along the guide groove 1004. Under the guidance of the guide groove 1004, the end of the driving rod 8 moves toward the end of the notch 201, and the pushing pin 801 at the end of the driving rod 8 moves along the driving groove 701. Under the guidance of the driving groove 701, the driving plate 7 drives the L-shaped clamping plate 5 to approach the side wall of the laser body 28, and finally the laser body 28 is clamped and positioned by the two L-shaped clamping plates 5. After the detection is completed, the detection table 2 continues to rotate, and the laser body 28 at the detection position leaves. During the process of the laser body 28 leaving the detection position, the sliding pin 802 moves along the guiding groove 1004. Under the guiding action of the guiding groove 1004, the end of the driving rod 8 moves away from the end of the slot 201, pushing the pin 801 to move along the driving groove 701 and enter the arc-shaped groove 1003. Driven by the driving groove 701, the driving plate 7 drives the L-shaped clamping plate 5 to move away from the side wall of the laser body 28 and approach it. The two L-shaped clamping plates 5 cancel the clamping and positioning of the laser body 28, facilitating the rapid replacement of the detection sample.

[0034] As a further embodiment of the present invention, the driving groove 701 includes a driving inclined groove 702 and a driving straight groove 703; As a further embodiment of the present invention, the clamping and conveying mechanism includes: A fixing plate 11, the fixing plate 11 is slidably connected in the slot 201. A spring 12 is connected between the fixing plate 11 and the slot 201. The power connector 4 is fixedly connected to the fixing plate 11, and the fixing plate 11 is slidably connected to the two driving rods 8; Two pushing blocks 13, the two pushing blocks 13 are symmetrically arranged on the back of the fixing plate 11, and the two pushing blocks 13 are respectively fixedly connected to the surfaces of the two driving rods 8; Specifically, during the process of the driving rod 8 moving towards the end of the slot 201, the pushing pin 801 first moves along the driving inclined groove 702. Driven by the driving inclined groove 702, the driving plate 7 drives the L-shaped clamping plate 5 to approach the side wall of the laser body 28. Finally, the laser body 28 is clamped and positioned by the two L-shaped clamping plates 5. Subsequently, the driving rod 8 continues to move towards the end of the slot 201, and the pushing pin 801 moves along the driving straight groove 703. At this time, the pushing block 13 contacts the back of the fixing plate 11 and pushes the fixing plate 11 to move, so that the fixing plate 11 drives the power connector 4 to move towards the interface on the laser body 28 and finally connects the power connector 4 to the interface; During the process of the driving rod 8 moving away from the end of the slot 201, the pushing pin 801 first moves along the driving straight groove 703, causing the pushing block 13 to move away from the back of the fixing plate 11. Under the action of the spring 12, the fixing plate 11 drives the power connector 4 to reset, and the power connector 4 is separated from the interface. After the power connector 4 is separated from the interface, the pushing pin 801 moves along the driving inclined groove 702. Under the guiding of the driving inclined groove 702, the two L-shaped clamping plates 5 cancel the clamping and positioning of the laser body 28, facilitating the rapid replacement of the detection sample; The above technical solution realizes: Before the power connector 4 is plugged in, the laser body 28 is adjusted and positioned by the two L-shaped clamping plates 5 first to ensure accurate plugging of the power connector 4 into the interface; After the power connector 4 leaves the interface, the two L-shaped clamping plates 5 are then released from clamping and positioning the laser body 28 to ensure that the power connector 4 can smoothly leave the interface.

[0035] The working principle of the present invention is as follows: A plurality of laser bodies 28 to be detected are placed in the notch 201, and the bottom surface of the laser body 28 contacts the top surface of the L-shaped clamping plate 5. Subsequently, the rotation drive mechanism is started, causing the detection table 2 to rotate. The rotation of the detection table 2 drives the plurality of laser bodies 28 to rotate, and the plurality of laser bodies 28 sequentially pass through the detection position. During the process of the detection table 2 rotating to drive the laser body 28 to move to the detection position, through the first pushing and adjusting mechanism at the corresponding position, the two L-shaped clamping plates 5 corresponding to the detection position are driven, so that the two L-shaped clamping plates 5 approach each other, adjust the position of the laser body 28 and clamp the laser body 28. After the two L-shaped clamping plates 5 adjust the position of the laser body 28 and clamp it, through the clamping and conveying mechanism, the power connector 4 at the detection position is driven to move, so that the power connector 4 is inserted into the laser body 28, thereby starting the laser body 28. The light-emitting port of the laser body 28 emits a laser signal to the optical power meter probe 27. After the detection is completed, the detection table 2 is driven to rotate by the rotation drive mechanism, and the laser body 28 leaves the detection position (the laser body 28 at the next position moves to the detection position and is positioned and detected according to the above operations). During the process of the laser body 28 leaving the detection position, first, through the clamping and conveying mechanism, the power connector 4 at the detection position is driven to move, and the power connector 4 is separated from the laser body 28. The laser body 28 is turned off, and the light-emitting port stops emitting the laser signal (at this time, the two L-shaped clamping plates continue to clamp the laser body 28 to ensure the stability of the laser body 28 during the process of pulling out the power connector 4). After the power connector 4 is separated from the laser body 28, through the first pushing and adjusting mechanism, the two L-shaped clamping plates 5 are separated from each other, and the operator replaces a new detection sample.
