Description

Technical Field

[0001] This application relates to the technical field of semiconductor laser testing, and in particular to a semiconductor laser loading, storage and testing device. Background Technology

[0002] Semiconductor lasers, as a highly efficient and compact light source, including the laser body and the contacts electrically connected to it, are widely used in communications, medical, industrial processing, and consumer electronics. With technological advancements, the performance requirements for semiconductor lasers are increasingly stringent, making reliability and stability key performance indicators.

[0003] However, semiconductor lasers are susceptible to material defects, process fluctuations, and operating environment during manufacturing and use, leading to drift or degradation in parameters such as output power, wavelength, and beam quality, and in severe cases, even device failure. Therefore, rapid and accurate testing and performance evaluation of semiconductor lasers are crucial.

[0004] For example, a laser loading, storage, and testing device (publication number CN215218012U) includes a housing, a metal mainline, a battery, and an insulating cylinder. In use, the positive and negative pins of the semiconductor laser are inserted into the paired insulating cylinders to achieve automatic electrical connection. This device features reliable connection and simple operation, significantly improving testing efficiency, avoiding the tedious manual wiring, and allowing simultaneous testing of multiple lasers, further enhancing testing efficiency.

[0005] During laser testing, the insulating cylinder is prone to wear due to the mechanical stress caused by repeated insertion and removal of the pins over a long period. Existing technical solutions have the following main drawbacks: First, the testing process uses only a single-connection method. This single-contact design is prone to false open circuits due to unstable contact, causing the laser to fail to light up properly, thus creating a risk of misjudgment and affecting the accuracy of the test results.

[0006] Secondly, the existing testing process has a significant efficiency bottleneck. That is, the lasers that have been tested must be completely removed before the next batch of lasers can be plugged in. This serial operation mode affects the testing efficiency of the lasers.

[0007] Based on this, and given the above viewpoints, there is still room for improvement in existing technologies. Summary of the Invention

[0010] A camera, used to record the emission of a detection laser, is mounted on the top of the through cylinder via support rods symmetrically arranged along the width of the conveyor belt.

[0011] A reversing clamping assembly is mounted on the through cylinder and used to reverse the direction of the through cylinder.

[0013] Preferably, the placement plate extends through the conveyor belt and has through slots for inserting laser contacts, and the bottom of the placement plate is equipped with electrical connection blocks that correspond one-to-one with the through slots, and the electrical connection blocks have connection slots.

[0014] Preferably, the conveyor belt is provided with conveyor rollers at both ends, and the conveyor rollers are provided with corresponding support frames at both ends. The two ends of the conveyor rollers are rotatably mounted on the support frames on the corresponding sides through bearings. The conveyor belt is arranged on the two conveyor rollers, and the conveyor rollers are provided with annular grooves to accommodate the electrical connection blocks.

[0015] Preferably, a fixed frame is provided above the conveyor belt, the fixed frame is installed on the support frame on the corresponding side by a fixed connecting rod, and the reversing clamping assembly is installed on the fixed frame.

[0016] Preferably, the reversing clamping assembly includes an annular frame rotatably disposed at the bottom of the circumferential surface of the through cylinder, a plurality of circumferentially evenly distributed and automatically reset locking blocks are disposed through the bottom of the circumferential surface of the through cylinder, and the portion of the locking blocks located outside the through cylinder is provided with a guide slope, and the bottom of the annular frame is provided with a plurality of guide rods corresponding one-to-one with the locking blocks and cooperating with the guide slopes on the corresponding locking blocks.

[0017] The fixed frame is also equipped with a lifting section for lifting the through cylinder.

[0018] Preferably, a rack plate is slidably mounted on the fixed frame, and a gear meshing with the rack plate is mounted on the annular frame. An annular rubber ring is installed on the through cylinder, and an annular rod that cooperates with the annular rubber ring is slidably mounted on the through cylinder. The annular rod is mounted on the fixed frame through a support connecting rod.

[0019] Preferably, the lifting part includes a lifting cylinder mounted on a fixed frame, a lifting connecting frame is mounted on the telescopic end of the lifting cylinder, and a through cylinder is rotatably mounted on the lifting connecting frame.

[0020] Preferably, the power-conducting component includes a vertical plate installed at the bottom of the fixed frame and corresponding to the through cylinder. Conductive rods are symmetrically arranged on the vertical plate along its width direction and are installed through the vertical plate. A connecting plate that mates with the connecting groove is installed at the end of the conductive rod away from the vertical plate. Telescopic spring rods are symmetrically arranged on the connecting plate along its height direction. An electrical transition block that is electrically connected to the conductive rod is installed at the end of the telescopic spring rod away from the connecting plate. A guide slope is provided on the electrical transition block.

[0021] Preferably, a movable plate is slidably disposed on the vertical plate along the width direction of the conveyor belt, and a wobbling block is installed at the end of the movable plate away from the vertical plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This invention utilizes a highly efficient and coordinated transmission structure formed by a conveyor belt and conveyor rollers. Specifically, during laser testing, the laser to be tested can be pre-inserted and fixed onto a placement plate. The continuous operation of the conveyor belt enables pre-loading before testing. This avoids the intermittent process of reloading and re-loading after testing, effectively preventing the repetitive operation of picking up and placing the laser after testing, reducing loading time, and significantly improving overall testing efficiency.

[0024] 2. After the laser completes the first test, the laser probes are reversed by driving the through cylinder. The laser probes then exit from the through slots of the first test and rotate 180 degrees around the axis of the through cylinder to swap the positions of the laser probes. Finally, after the laser probes are swapped, they are inserted into the adjacent through slots on the same placement plate for a second test.

[0025] This dual-slot alternating detection design utilizes mechanical reversal to achieve spatial transformation of the contact points, effectively avoiding contact defects caused by single contact. Furthermore, by cross-checking the results of two independent tests, it eliminates the risk of misjudgment caused by false open circuits and improves data reliability and laser detection accuracy through redundant detection.

[0037] The following is in conjunction with the appendix Figures 1 to 10This application will be described in further detail.

[0038] This application discloses a semiconductor laser loading, storage, and detection device. Through this dual-slot alternating detection design, the spatial conversion of contact points is achieved by mechanical reversal, which can effectively avoid the contact failure problem caused by single contact. Furthermore, by cross-checking the results of two independent detections, the risk of misjudgment caused by false open circuits can be eliminated, and the data reliability and detection accuracy can be improved through redundant detection.

[0039] Example 1

[0040] A semiconductor laser loading, storage and testing device includes a conveyor belt 1 for conveying lasers 100, a plurality of placement plates 2 for placing lasers 100 are uniformly arranged on the conveyor belt 1 along its length direction, and a testing mechanism 3 for testing lasers 100 is arranged in the middle of the upper part of the conveyor belt 1.

[0041] The placement plate 2 passes through the conveyor belt 1 and has a through groove 21 for inserting the laser 100 contact pin. The bottom of the placement plate 2 is equipped with an electrical connection block 22 that corresponds to the through groove 21. The electrical connection block 22 has a connection groove 23.

[0042] The conveyor belt 1 is provided with conveyor rollers 11 at both ends, and the conveyor rollers 11 are provided with corresponding support frames 12 at both ends. The two ends of the conveyor rollers 11 are rotatably mounted on the support frames 12 on the corresponding sides through bearings. The conveyor belt 1 is provided on the two conveyor rollers 11, and the conveyor rollers 11 are provided with annular grooves 13 for the electrical connection block 22 to make way.

[0043] Among them, such as Figure 1 The arrows indicate the feeding and conveying direction of the laser 100. In actual operation, the laser 100 is placed on the placement plate 2 at the starting position, and the laser 100 contacts are inserted into the through slot 21 and then inserted into the electrical connection block 22. At this time, an existing drive motor (not shown in the figure) is used to drive any conveying roller 11 to rotate through belt drive. Since belt drive is a common knowledge, it is not shown in the figure.

[0044] During the rotation of conveyor roller 11, it cooperates with another conveyor roller 11 to form a power transmission structure that drives the conveyor belt 1 to move. When the drive end conveyor roller 11 rotates under the drive of the servo motor, the other driven conveyor roller 11 cooperates synchronously, relying on friction or meshing transmission to drive the conveyor belt 1 to move in a straight line. When the placement plate 2 fixed on the surface of the conveyor belt 1 moves with the conveyor belt 1, it will synchronously push the laser 100 to complete the loading action, so that the laser 100 is accurately moved to the designated position of the detection mechanism 3.

[0045] The drive motor here is a servo motor, which can precisely drive the conveyor roller 11 to rotate a specified number of revolutions. In the transmission design of this invention, each time the servo motor completes a specified number of revolutions, it can move the belt body a specific distance through the transmission cooperation between the conveyor roller 11 and the conveyor belt 1. This distance is exactly equal to the distance between adjacent placement plates 2, thereby ensuring that the laser 100 can achieve precise positioning and switching between workstations with the placement plate 2.

[0046] The annular groove 13 can make way for the electrical connection block 22, thus avoiding the possibility of the electrical connection block 22 colliding with the conveyor roller 11 when it moves to the conveyor roller 11.

[0047] The detection mechanism 3 includes a through cylinder 31, which is a structure that runs through the length of the conveyor belt 1 and is located above the middle of the conveyor belt 1, and rotates around its axis.

[0048] Camera 32, used to record the emission of detection laser 100, is mounted on the top of the through cylinder 31 via support rods symmetrically arranged along the width of conveyor belt 1.

[0049] The reversing clamping assembly 33 is disposed on the through cylinder 31 and is used to reverse the direction of the through cylinder 31.

[0050] The power supply component 34 corresponds to the placement plate 2 closest to the through cylinder 31 and is used to power the laser 100 being detected.

[0051] A fixed frame 14 is provided above the conveyor belt 1. The fixed frame 14 is installed on the support frame 12 on the corresponding side by a fixed connecting rod, and the reversing clamping assembly 33 is installed on the fixed frame 14.

[0052] The power-conducting component 34 includes a vertical plate 341 installed at the bottom of the fixed frame 14 and corresponding to the through cylinder 31. Conductive rods 342 are symmetrically arranged on the vertical plate 341 along its width direction, and the conductive rods 342 are installed through the vertical plate 341. A connecting plate 343 that cooperates with the connecting groove 23 is installed at the end of the conductive rod 342 away from the vertical plate 341. Telescopic spring rods 344 are symmetrically arranged on the connecting plate 343 along its height direction. An electrical transition block 345 that is electrically connected to the conductive rod 342 is installed at the end of the telescopic spring rod 344 away from the connecting plate 343. A guide slope is provided on the electrical transition block 345.

[0053] Each time the conveyor belt 1 moves, it moves the laser 100 corresponding to the placement plate 2 to directly below the through cylinder 31. The ends of the two conductive rods 342 away from the electrical connection block 22 are respectively electrically connected to the positive and negative terminals of the power supply. In specific operation, when the conveyor belt 1 moves the laser 100 to be tested directly below the through cylinder 31 through the placement plate 2, the laser 100 body is coaxial with the through cylinder 31. During the process of the laser 100 moving directly below the through cylinder 31, the corresponding placement plate 2 synchronously moves the electrical connection block 22. When the electrical connection block 22 moves to the electrical transition block 345, it comes into contact with the guide slope. At this time, the guide slope on the electrical transition block 345 is squeezed by the upper and lower sides of the connecting groove 23.

[0054] The electrical transition blocks 345 corresponding to the same connecting plate 343 move towards the connecting plate 343 at the same time, that is, the distance between the two electrical transition blocks 345 decreases until the two electrical transition blocks 345 move into the connecting groove 23. At this time, the power supply, conductive rod 342, electrical transition block 345, electrical connecting block 22 and laser 100 form a closed circuit, and then the emission of laser 100 is observed.

[0055] If the laser 100 to be tested is qualified at this time, the laser 100 can emit laser light normally, and the emitting status of the laser 100 is recorded by the camera 32.

[0056] If the laser 100 does not emit light normally, the position of the laser 100 contact pin is changed for a second test. Specifically, the reversing clamping assembly 33 includes an annular frame 331 rotatably disposed at the bottom of the circumferential surface of the through cylinder 31. Multiple circumferentially evenly distributed and automatically reset locking blocks 332 are disposed through the bottom of the circumferential surface of the through cylinder 31. The portion of the locking block 332 located outside the through cylinder 31 is provided with a guide slope. The bottom of the annular frame 331 is provided with multiple guide rods 333 that correspond one-to-one with the locking blocks 332 and cooperate with the guide slopes on the corresponding locking blocks 332.

[0057] The fixed frame 14 is also equipped with a lifting part 334 for lifting the through cylinder 31.

[0058] The lifting unit 334 includes a lifting cylinder 335 mounted on a fixed frame 14. A lifting connecting frame 336 is mounted on the telescopic end of the lifting cylinder 335, and the through cylinder 31 is rotatably mounted on the lifting connecting frame 336.

[0059] A rack plate 141 is slidably mounted on the fixed frame 14, and a gear 142 that meshes with the rack plate 141 is mounted on the ring frame 331. An annular rubber ring 143 is installed on the through cylinder 31, and an annular rod 144 that cooperates with the annular rubber ring 143 is slidably mounted on the through cylinder 31. The annular rod 144 is mounted on the fixed frame 14 through a support connecting rod.

[0060] The annular rod 144 has an annular connecting groove, the rack plate 141 is high enough, and the gear 142 can slide up and down on the rack plate 141. The locking block 332 has a connecting protrusion at the end away from the through cylinder 31, and a return spring rod for resetting the locking block 332 is installed between the connecting protrusion and the circumferential surface of the through cylinder 31. In specific operation, when the laser 100 does not emit light normally, the lifting cylinder 335 is activated. During the movement of the extension end of the lifting cylinder 335, the through cylinder 31 is driven to move down through the lifting connecting frame 336. During the downward movement of the through cylinder 31, its bottom moves down to the side of the laser 100 body, that is, the laser 100 body is located inside the through cylinder 31. At this time, the lifting cylinder 335 is closed.

[0061] At this time, the rack plate 141 is driven to move in the opposite direction to the feeding direction of the laser 100 by an externally driven slider (electric slider, etc., which is common knowledge and therefore not shown in the figure). During the movement of the rack plate 141, it meshes with the gear 142 to drive the ring frame 331 to rotate. During the rotation of the ring frame 331, it drives the guide rod 333 to rotate synchronously. During the rotation of the guide rod 333, it comes into contact with the guide inclined surface and moves into the through cylinder 31 by pressing the locking block 332 through the guide inclined surface. During the movement of the locking block 332, it clamps the laser 100 body. At this time, the return spring rod is stretched.

[0062] At this time, the annular rubber ring 143 is engaged inside the annular connecting groove, thereby increasing the friction between the annular rubber ring 143 and the annular rod 144. As a result, the through cylinder 31 remains relatively stationary through the cooperation of the annular rubber ring 143 and the annular rod 144. That is, the through cylinder 31 will not rotate on the lifting frame 336 when clamping the laser 100, thus ensuring the stability of the through cylinder when clamping the laser 100. In addition, the relative stationary state between the through cylinder 31 and the annular rod 144 can also ensure that when the annular rod 144 drives the guide rod 333 to press against the locking block 332, the possibility of relative rotation of the through cylinder 31 is avoided, thus ensuring the locking effect of the locking block 332 on the through cylinder 31.

[0063] After the locking block 332 clamps the laser 100 body, the rack plate 141 stops moving, and the ring frame 331 drives the guide rod 333 to remain stationary. At this time, the locking block 332 remains fixed, and the lifting cylinder 335 is activated, which drives the through cylinder 31 to move upward through the lifting connecting frame 336. During the upward movement of the through cylinder 31, the laser 100 is removed from the placement plate 2 with the help of the locking block 332, and at the same time, the laser 100's contact pins are pulled out from the through groove 21. After the laser 100 and its contact pins are completely separated from the placement plate 2, the lifting cylinder 335 is closed.

[0064] Subsequently, the rack plate 141 is driven by an externally driven slider to continue moving in the opposite direction to the feeding direction of the laser 100. As the rack plate 141 moves, it meshes with the gear 142, causing the ring frame 331 to rotate. The ring frame 331 simultaneously drives the guide rod 333 to rotate. Because the locking block 332 is pressed against the laser 100 body at this time, the guide rod 333 remains against the guide slope. Furthermore, the engagement of the locking block 332 and the guide rod 333 creates a barrier, keeping the ring frame 331 and the through cylinder 31 relatively stationary. Driven by the rack plate 141, the gear 142 and the ring frame 331 work together to rotate the through cylinder 31 on the lifting frame. Through the linkage between the through cylinder 31 and the locking block 332, the lifted laser 100 rotates 180 degrees, achieving the interchange of the laser 100's contact positions.

[0065] After the contact pins of laser 100 are swapped, the lifting cylinder 335 is activated. The telescopic end of the lifting cylinder 335 drives the through cylinder 31 to move downward through the lifting bracket 336, allowing the laser 100 to be re-inserted into the through slot 21 after the contact pins are swapped. If the laser 100 to be tested is qualified, it can emit laser light normally, and the camera 32 records the emission of laser 100. Otherwise, it is unqualified. This dual-slot alternating detection design, which uses mechanical reversal to achieve spatial conversion of the contact point, can effectively avoid contact problems caused by single contact. Furthermore, by cross-checking the results of two independent tests, the risk of misjudgment caused by false open circuits can be eliminated, and the data reliability can be improved through redundant detection, thereby improving the detection accuracy of laser 100.

[0066] After the second inspection, the rack plate 141 and the through cylinder 31 are reset, the laser 100 at the corresponding station is released from the limit, and the inspection ends. If it is qualified, it is removed by the existing robot gripper (not shown in the figure). If it is unqualified, it is recycled.

[0067] Example 2

[0068] Based on Embodiment 1, in order to reduce the complexity of changing the contact pins of the laser 100, a pre-detection process can be performed on the laser 100 that does not emit light after one detection. Specifically, a movable plate 346 is slidably arranged through the vertical plate 341 along the width direction of the conveyor belt 1, and a wobbling block 347 is installed at the end of the movable plate 346 away from the vertical plate 341. A wobbling groove is opened on the wobbling block 347. A reset spring rod 348 is installed between the vertical plate 341 and the wobbling block 347. An L-shaped linkage plate 349 is provided at the bottom of the rack plate 141, and the vertical section of the linkage plate 349 is installed on the bottom of the rack plate 141. Multiple arc-shaped protrusions 340 are evenly arranged along the length direction on the horizontal section of the linkage plate 349, and a cylindrical block 3410 that cooperates with the arc-shaped protrusions 340 is provided on the linkage plate 349.

[0069] In specific operation, during the clamping process of the laser 100 body, the rack plate 141 moves, driving the linkage plate 349 to move. During the movement of the linkage plate 349, its horizontal section drives the arc-shaped protrusion 340 to move synchronously. When the arc-shaped protrusion 340 contacts the cylindrical block 3410, it drives the moving plate 346 to move a small distance towards the vertical plate 341. During the movement of the moving plate 346, it drives the wobbling block 347 to move a small distance towards the vertical plate 341. During the movement of the wobbling block 347, it causes the laser 100's contact pin to come into contact with the inner wall of the through groove 21 near the vertical plate 341. At this time, the reset spring rod 348 is stretched. When the arc-shaped protrusion 340 disengages from the cylindrical block 3410, the reset spring rod 348 resets, causing the wobbling block 347 to reset. At this time, the wobbling block 347 has a certain inertia during the reset process. During the reset process, the wobbling block 347 causes the laser 100 contact pin to come into contact with the inner wall of the through groove 21 on the side away from the vertical plate 341. Then, the above action is repeated to observe whether the laser 100 flickers frequently. If it flickers frequently, it indicates to a certain extent that the laser 100 is not damaged. Then, the laser 100 contact pin is repositioned and a second test is performed to further determine whether the laser 100 is qualified. If it does not flicker, it is removed in time, and there is no need to perform a second test.

[0070] The wobbling block 347 is made of rubber. Even if there is no wear inside the through groove 21, that is, there is no gap between the laser 100 contact and the through groove 21, the wobbling block 347 will not have a rigid collision with the laser 100 contact during the wobbling process, thus ensuring the contact effect between the wobbling block 347 and the laser 100 contact.

[0071] The implementation principle of this invention is as follows:

[0072] The laser 100 is placed on the placement plate 2 at the starting position, and the laser 100's contacts are inserted into the through slot 21 and then into the electrical connection block 22. At this time, an existing drive motor (not shown in the figure) is used to drive any conveyor roller 11 to rotate via belt drive. During the rotation of the conveyor roller 11, the conveyor belt 1 is moved, and as the placement plate 2 fixed on the surface of the conveyor belt 1 moves with the conveyor belt 1, it will synchronously push the laser 100 to complete the loading action, so that the laser 100 is accurately moved to the designated position of the detection mechanism 3.

[0073] When the conveyor belt 1 moves the laser 100 to be tested directly below the through cylinder 31 via the placement plate 2, with the laser body coaxial with the through cylinder 31, the placement plate 2 simultaneously moves the electrical connection block 22. The electrical connection block 22 moves to the electrical transition block 345 and comes into contact with the guide slope. The guide slope of the electrical transition block 345 is driven by the upper and lower sides of the connecting groove 23 to squeeze the telescopic spring rod 344. The two electrical transition blocks 345 corresponding to the same connecting plate 343 move towards the connecting plate 343 at the same time, with the distance between them decreasing, until they move into the interior of the connecting groove 23. At this time, the power supply, conductive rod 342, electrical transition block 345, electrical connection block 22 and laser 100 form a closed loop. Then the emission of the laser 100 is observed.

[0074] If the laser 100 to be tested is qualified at this time, the laser 100 can emit laser light normally, and the emitting status of the laser 100 is recorded by the camera 32.

[0075] If the laser 100 does not emit light normally, the lifting cylinder 335 is activated. Its telescopic end moves the through cylinder 31 down to the side of the laser 100 body via the lifting frame 336 and then closes. Subsequently, it drives the rack plate 141 to move in the opposite direction of feeding the laser 100. The rack plate 141 meshes with the gear 142, driving the ring frame 331 to rotate. The ring frame 331 drives the guide rod 333 to rotate synchronously. The guide rod 333 abuts against the guide slope and presses the locking block 332 to move into the through cylinder 31, clamping the laser 100 body and then pulling it out.

[0076] An externally driven slider moves the rack plate 141 in the opposite direction to the laser 100 feeding direction. The rack plate 141 meshes with the gear 142, driving the ring frame 331 to rotate. The ring frame 331 simultaneously drives the guide rod 333 to rotate. At this time, the locking block 332 presses against the laser 100 body, and the guide rod 333 abuts against the guide slope. Because the locking block 332 and the guide rod 333 cooperate to form a block, the ring frame 331 and the through cylinder 31 remain relatively stationary. Driven by the rack plate 141, the gear 142 cooperates with the ring frame 331, driving the through cylinder 31 to rotate on the lifting frame. Through the linkage between the through cylinder 31 and the locking block 332, the lifted laser 100 rotates 180 degrees, realizing the interchange of the laser 100's contact positions.

[0077] After the contact pins of laser 100 are swapped, the lifting cylinder 335 is activated. The extension end of the lifting cylinder 335 drives the through cylinder 31 to move down through the lifting frame 336, so that the contact pins of laser 100 are swapped and re-inserted into the through slot 21. If the laser 100 to be tested is qualified, it can emit laser light normally, and the emitting status of laser 100 is recorded by camera 32. Otherwise, it is unqualified.

[0078] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0079] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
