DETAILED DESCRIPTION

[0048] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0049] like Figures 1 to 9 A detection and positioning device for a semiconductor laser is shown, comprising:

[0050] The machine base 1 has a top end rotatably connected to a testing platform 2, and a rotation drive mechanism is provided inside the machine base 1 for driving the testing platform 2 to rotate;

[0051] An optical power meter probe 27 is provided at the detection position on the outer wall of the base 1 for receiving and detecting the optical power of the laser body 28;

[0052] 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 slots 201;

[0053] A first push adjustment mechanism adapted to the number of the slots 201, the first push adjustment mechanism and the rotary drive mechanism are linked to drive the two L-shaped clamping plates 5 corresponding to the detection position to clamp the laser body 28;

[0054] 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 by the clamping and conveying mechanism. The clamping and conveying mechanism cooperates with the first pushing and adjusting mechanism to drive the power connectors 4 at the detection position to be plugged into the laser body 28;

[0055] In the existing technology, during the laser detection and positioning process, the single-station operation mode requires frequent start-up and shutdown of the equipment to replace samples. When replacing samples, the power connector needs to be manually plugged in and out. This increases the detection cycle, reduces detection efficiency, and is not convenient for large-scale laser detection. This technical solution can solve the above problems. The specific operations are as follows:

[0056] 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. Then start the rotary drive mechanism to rotate the test platform 2. The rotation of the test platform 2 will drive the multiple laser bodies 28 to rotate. The multiple laser bodies 28 pass through the test position in sequence to complete the test.

[0057] During the process of the detection table 2 rotating and driving 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, so that the two L-shaped clamping plates 5 are close to each other, the position of the laser body 28 is adjusted, and the laser body 28 is clamped. This can improve the coincidence degree between the center of the light spot and the receiving surface of the optical power meter probe 27, thereby improving 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.

[0058] After the two L-shaped clamping plates 5 adjust the position of the laser body 28 and clamp it, the clamping and conveying mechanism drives the power connector 4 at the detection position to move, so that the power connector 4 is plugged into the laser body 28, thereby starting the laser body 28. The light outlet of the laser body 28 emits a laser signal to the optical power meter probe 27;

[0059] After the detection is completed, the detection table 2 is driven to rotate by the rotary 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). In the process of the laser body 28 leaving the detection position, the power connector 4 at the detection position is first driven to move by the clamping and conveying mechanism, so that the power connector 4 is separated from the laser body 28, the laser body 28 is closed, and the light outlet 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 adjustment mechanism drives the two L-shaped clamping plates 5 away from each other to release the clamping of the laser body 28, thereby facilitating the rapid replacement of new detection samples and improving detection efficiency.

[0060] As a further embodiment of the present invention, it also includes a power supply box 3, which is fixedly connected to the top of the detection platform 2, and the power line of the power connector 4 is connected to the power supply box 3; power is supplied to the power connector 4 through the power supply box 3.

[0061] As a further implementation scheme of the present invention, the L-shaped clamping plate 5 is a metal heat-conducting plate, and a temperature sensor 6 is provided on the side wall of the L-shaped clamping plate 5 to detect the temperature of the laser body 28 at the corresponding position in real time. According to the heating rate and temperature peak of the laser body 28, it is helpful to detect whether the heat dissipation of the laser body 28 is good.

[0062] As a further implementation scheme of the present invention, the rotary drive mechanism includes an annular rack 24, which is fixedly connected to the bottom end of the detection table 2. A self-locking motor 25 is fixedly connected to the base 1, and the output shaft of the self-locking motor 25 is fixedly connected to a transmission gear 26, which engages with the annular rack 24. By starting the self-locking motor 25, the transmission gear 26 is driven to rotate, and under the meshing action, the annular rack 24 is rotated, thereby driving the detection table 2 to rotate, thereby realizing the transportation of the laser body 28 to the detection position.

[0063] As a further implementation scheme of the present invention, it also includes several mounting plates 21, and the several mounting plates 21 are respectively fixedly connected to the ends of the slots 201. The bottom ends of the mounting plates 21 are fixedly connected to a reading head 22, and the top ends of the machine base 1 are fixedly connected to an annular magnetic scale 23. By setting the reading head 22 and the annular magnetic scale 23, a detection point is set on the annular magnetic scale 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 by the external controller to ensure that the laser body 28 is accurately moved to the detection position, thereby improving the overlap between the center of the light spot and the receiving surface of the optical power meter probe 27 and reducing the detection error.

[0064] As a further embodiment of the present invention, it also includes a guide rail 17, which is fixedly connected to the machine base 1, and a slider 19 is driven by a screw rod 18 in the guide rail 17 (the screw rod 18 is rotatably installed in the guide rail 17, and the slider 19 is threadedly sleeved on the screw rod 18), and an optical power meter probe 27 is fixedly connected to the top of the slider 19, and a knob 20 is fixedly connected to the end of the screw rod 18; during the detection process, the screw rod 18 can be rotated by rotating the knob 20, and the scale indication on the guide rail 17 can be cooperated with to flexibly adjust the position of the optical power meter probe 27 according to the detection requirements, and adjust the distance between the optical power meter probe 27 and the light outlet, thereby effectively preventing the optical power meter probe 27 from being ablated due to high energy density.

[0065] It should be noted that the optical power meter probe 27 is fixed to the top of the slider 19 by bolts. There are multiple sets of threaded holes on the top of the slider 19 to facilitate the adjustment of the position of the optical power meter probe 27, ensure that the laser body 28 is accurately moved to the detection position, and improve the overlap between the center of the light spot and the receiving surface of the optical power meter probe 27.

[0066] As a further embodiment of the present invention, it also includes:

[0067] Two flip clamping plates 14, the two flip clamping plates 14 are symmetrically rotated and connected to the two ends of the L-shaped clamping plate 5;

[0068] Two driving gears 15 are symmetrically connected to the two ends of the L-shaped clamping plate 5, and the driving gears 15 are coaxially fixed with the flip clamping plate 14 at the corresponding position;

[0069] Two drive racks 16 , the two drive racks 16 are engaged with the drive gear 15 , and the drive racks 16 are fixedly connected in the notch 201 ;

[0070] Specifically, by setting the flip clamping plate 14, the driving gear 15 and the driving rack 16, when the two L-shaped clamping plates 5 approach 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 flip clamping plate 14, clamping the front and rear ends of the laser body 28, and further adjusting the position of the laser body 28. On the one hand, it ensures that during the detection process, the light outlet of each laser body 28 maintains the same distance from the optical power meter probe 27, thereby improving the detection accuracy. On the other hand, it ensures that the power connector 4 is at the same distance from the interface on the laser body 28, which is conducive to accurately connecting the power connector 4 with the interface on the laser body 28, avoiding the problem of the power connector 4 being over-inserted or not fully inserted into the interface.

[0071] As a further embodiment of the present invention, the first push adjustment mechanism includes: two drive plates 7, the two drive plates 7 are respectively fixedly connected to the side walls of the two L-shaped clamping plates 5, and the top of the drive plate 7 is provided with a drive groove 701;

[0072] Two driving rods 8 are symmetrically slidably connected in the slot 201 , and a push pin 801 is fixed to the end of the driving rod 8 , and the push pin 801 is slidably connected in the driving slot 701 at the corresponding position.

[0073] Push the adjustment assembly, which is linked to the rotation drive mechanism. When the laser body 28 rotates to the position of the optical power meter probe 27, the adjustment assembly is pushed to extend the two drive rods 8 at the target position. Under the guidance of the drive slot 701, the two L-shaped clamping plates 5 approach each other.

[0074] The push adjustment assembly includes: a column 9, the bottom end of which is fixedly connected to the base 1;

[0075] The annular drive frame 10 is fixedly connected to the top of the column 9 and is rotatably connected to the bottom end of the detection platform 2;

[0076] The upper track groove 1001 and the lower track groove 1002 are respectively provided on the upper bottom surface and the lower bottom surface of the annular driving frame 10;

[0077] The upper track groove 1001 and the lower track groove 1002 both have an arc-shaped groove 1003 , both ends of the arc-shaped groove 1003 are connected to a guide groove 1004 , the ends of the two guide grooves 1004 are connected to each other, and the connection point of the two guide grooves 1004 ends is located at the position of the optical power meter probe 27 ;

[0078] Two sliding pins 802, the two sliding pins 802 are fixedly connected to the ends of the driving rod 8, and the sliding pins 802 at corresponding positions are slidably connected in the upper track groove 1001 and the lower track groove 1002 respectively;

[0079] 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 position, the two sliding pins 802 are located in the arc groove 1003. During the movement of the laser body 28 toward the detection position, 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.

[0080] After the detection is completed, the detection table 2 continues to rotate, and the laser body 28 on the detection position leaves. In the process of the laser body 28 leaving the detection position, the sliding pin 802 moves along the guide groove 1004. Under the guidance of the guide 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 groove 1003. Under the drive in the driving groove 701, the driving plate 7 drives the L-shaped clamping plate 5 away from the side wall of the laser body 28, and the two L-shaped clamping plates 5 cancel the clamping positioning of the laser body 28, which is convenient for quick replacement of the detection sample.

[0081] As a further embodiment of the present invention, the driving groove 701 includes a driving inclined groove 702 and a driving straight groove 703;

[0082] As a further embodiment of the present invention, the clamping and conveying mechanism comprises:

[0083] The fixing plate 11 is slidably connected in the notch 201 , a spring 12 is connected between the fixing plate 11 and the notch 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 ;

[0084] Two pushing blocks 13, the two pushing blocks 13 are symmetrically arranged on the back of the fixed plate 11, and the two pushing blocks 13 are respectively fixedly connected to the surfaces of the two driving rods 8;

[0085] Specifically, when the driving rod 8 moves toward the end of the slot 201, the pushing pin 801 first moves along the driving oblique groove 702. Driven by the driving oblique groove 702, 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. Then, the driving rod 8 continues to move toward 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 toward the interface on the laser body 28, and finally the power connector 4 is connected to the interface.

[0086] When the driving rod 8 moves away from the end of the notch 201, the pushing pin 801 first moves along the driving straight groove 703, so that the pushing block 13 moves away from the back of the fixed plate 11. Under the action of the spring 12, the fixed 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 oblique groove 702. Under the guidance of the driving oblique groove 702, the two L-shaped clamping plates 5 cancel the clamping position of the laser body 28, which facilitates the rapid replacement of the test sample.

[0087] The above technical solution achieves:

[0088] Before plugging in the power connector 4, first adjust and position the laser body 28 using the two L-shaped clamping plates 5 to ensure that the power connector 4 is accurately plugged into the interface;

[0089] After the power connector 4 is removed from 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 be removed from the interface smoothly.

[0090] The working principle of the present invention is as follows: multiple laser bodies 28 to be inspected are placed 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. Then, the rotary drive mechanism is activated to rotate the inspection platform 2. The rotation of the inspection platform 2 drives the multiple laser bodies 28 to rotate, and the multiple laser bodies 28 pass through the inspection position in sequence.

[0091] During the process of the detection platform 2 rotating and driving 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, so that the two L-shaped clamping plates 5 are close to each other, and the position of the laser body 28 is adjusted and the laser body 28 is clamped.

[0092] After the two L-shaped clamping plates 5 adjust the position of the laser body 28 and clamp it, the clamping and conveying mechanism drives the power connector 4 at the detection position to move, so that the power connector 4 is plugged into the laser body 28, thereby starting the laser body 28. The light outlet of the laser body 28 emits a laser signal to the optical power meter probe 27;

[0093] After the detection is completed, the detection table 2 is driven to rotate by the rotary 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). In the process of the laser body 28 leaving the detection position, the power connector 4 at the detection position is first driven to move by the clamping and conveying mechanism, and the power connector 4 is separated from the laser body 28. The laser body 28 is closed, and the light outlet stops emitting laser signals (at this time, the two L-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, the first pushing adjustment mechanism is used to move the two L-shaped clamping plates 5 away from each other, and the personnel replace the new detection sample.

[0094] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
