Description

Technical Field

[0001] The present invention relates to the field of detecting the length of a probing electrode, and more particularly to a device for detecting the length of a probing electrode of a semiconductor laser. Background Art

[0002] In recent years, due to the unique characteristics of semiconductor lasers, such as small size, light weight, high efficiency and high reliability, they have been more and more widely used in the fields of medical treatment, display lighting, laser processing and military. In the process of semiconductor laser packaging, in order to improve the quality of the laser and screen out the lasers with unqualified performance in time, the commonly adopted screening method is to use a pulse or DC power supply to set a certain range of output voltage and current. The output end of the power supply is connected to a probing electrode with good electrical conductivity, and the probing electrode is connected to the positive and negative electrodes of the laser. The laser is powered on through the probing electrode, so as to carry out the aging and testing work of the laser. As a connecting structure between the power supply and the laser, the probing electrode plays a very important role in the aging and testing process of the laser.

[0003] In the process of laser production, in order to improve the production efficiency, a set of aging test fixtures has multiple groups of probing electrodes to simultaneously carry out aging tests on multiple lasers. Since there are certain deviations in the length dimensions of the probing electrodes during the processing, if the deviation exceeds a certain range, during the aging test, some lasers will have poor contact due to the inconsistent height of the probing electrodes, resulting in the lasers being burned out. Therefore, before using the probing electrode, it is necessary to detect the length of the probing electrode and screen out the probing electrodes whose detected values exceed the required range.

[0004] The commonly adopted method for detecting the probing electrode is to measure the length of the probing electrode one by one with a vernier caliper, and judge the quality of the probing electrode according to the measurement results. This method for detecting the probing electrode is relatively simple, but the efficiency is relatively low. Moreover, different operators apply different forces to the vernier caliper during detection, resulting in different detection data deviations, poor detection accuracy and consistency, and it is easy to damage the surface of the probing head during the detection process, affecting the quality of the probing electrode. With the increasing usage of probing electrodes, this detection method cannot meet the needs of batch detection, and there is no special device for detecting the length of probing electrodes on the market at present. Therefore, a device and a detection method for detecting the length of a probing electrode of a semiconductor laser, which have a simple structure, are easy to operate, have high detection efficiency, high precision and good consistency, are needed to solve the problems existing in the current detection of the length of probing electrodes.

Detailed implementation manners

[0031] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0032] Such as Figure 1As shown in the figure, a device for detecting the length of the probing electrode of a semiconductor laser includes a base 1, a bracket 2 arranged on the base 1, a feeding mechanism 4 arranged on the bracket 2 for sequentially feeding the probing electrode 3, a turning mechanism 5 arranged on the bracket 2 for supporting the probing electrode 3 to be detected, a detecting mechanism 6 arranged on the bracket 2 for detecting the length of the probing electrode 3, and a transfer mechanism 7 arranged on the base 1 for pushing out the probing electrode after the detection is completed. The base 1 is located at the lower end of the device, and a portal-shaped bracket 2 is arranged at the upper end of the base 1. A fixing plate is arranged at the upper end of the bracket 2, and the feeding mechanism 4 is installed on the fixing plate. During the detection process, the device start switch is pressed, and the probing electrode to be detected is placed at the upper end of the feeding mechanism by an automatic feeding machine, and then slides downward and is evenly arranged in the feeding mechanism. The lowermost probing electrode enters the position of the turning mechanism 5, and the detecting mechanism 6 detects the length of the probing electrode 3. After the detection is completed, the turning mechanism 5 drives the probing electrode 3 to turn over and fall to the transfer mechanism 7 for output. It has a high degree of automation and is convenient to operate. The entire detection process runs automatically and continuously. The efficiency of detecting the length of the probing electrode is 5 - 10 times higher than that of the previous manual operation. When using this device to detect the length of the probing electrode, it avoids the damage to the surface of the probing head during manual detection and effectively improves the detection quality of the probing electrode. By using this device to detect the length of the probing electrode, one person can operate multiple devices simultaneously, greatly reducing the production labor cost.

[0033] As Figure 2 shown, the feeding mechanism 4 includes fixing frames 41 symmetrically arranged on the bracket 2, baffles 42 symmetrically arranged in the fixing frames 41, and inclined surfaces 43 arranged at the lower ends of the two baffles 42. The feeding mechanism 4 is used to place multiple probing electrodes 3 to be detected. The probing electrode 3 is supported on the inclined surface 43 to limit the probing electrode 3, and due to the self-gravity of the probing electrode 3, the probing electrode 3 can slide downward automatically. A sloped surface 17 is respectively arranged on the inner side of each baffle 15, and the surface of the sloped surface 17 is smooth. The angle of the sloped surface 17 is 30 - 60°, and the probing electrode 7 can slide downward freely on the sloped surface 17.

[0034] As Figure 3 and Figure 7 shown, the turning mechanism 5 includes a turning roller 51 arranged on the bracket 2 and rotating on the bracket 2. A V-shaped groove 52 is arranged on the outer cylindrical surface of the turning roller 51. The rotating shaft of the turning roller 51 is supported on the bracket 2 through a bearing. A motor is arranged on the bracket 2, and the output shaft of the motor is connected to the rotating shaft of the turning roller 51 through a belt to drive the turning roller 51 to rotate 360°. The number of V-shaped grooves 52 is 2. The probing electrode 3 falls into the V-shaped groove 52, and the detecting mechanism 6 detects the length of the probing electrode 3 in the V-shaped groove 52.

[0035] As Figure 4As shown in the figure, the detection mechanism 6 includes a fixed rod 61 provided at the lower end of the left baffle 42 and a displacement sensor 62 provided at the lower end of the right baffle 42. The displacement sensor 62 is coaxial with the fixed rod 61. The displacement sensor 62 uses a high-precision glass grating displacement sensor. After the detection electrode 3 falls into the V-shaped groove 52, the fixed rod 61 positions the left end of the detection electrode 3. The high-precision glass grating displacement sensor contacts the right end of the detection electrode 3, and the high-precision glass grating displacement sensor detects the length dimension of the detection electrode 7. The high-precision glass grating displacement sensor has a maximum detection accuracy of ±0.003 mm. By using the high-precision glass grating displacement sensor instead of the vernier caliper for detection, the detection accuracy is improved from ±0.05 mm before to ±0.003 mm, and the accuracy and reliability of the detection data are greatly improved.

[0036] As Figure 2 shown in the figure, a cross bar 44 passing through the baffle 42 is provided inside the fixing frame 41. In this embodiment, there are three cross bars 44. Two cross bars 44 are provided at the upper end of the fixing frame 41, and one cross bar 44 is provided at the lower end of the fixing frame 41. One baffle 42 is provided on each inner side of the two fixing frames 41. A sleeve cooperating with the cross bar 44 is provided on the baffle 42 and is positioned by screws, and the interval between the two baffles 42 can be adjusted according to the length of the electrode to be measured.

[0037] As Figure 3 shown in the figure, a discharge port 53 is provided on the bracket 2 at the position of the turning roller 51. A sliding frame 54 is provided inside the discharge port 53. After the length measurement of the detection electrode is completed, the turning roller 51 rotates, and the detection electrode falls from the V-shaped groove 52 into the sliding frame 54 and slides to the transfer mechanism 7.

[0038] As Figure 3 shown in the figure, locking blocks 45 that move up and down on the baffle 42 are provided at the inclined plane positions of the two baffles 42. A positioning block 46 is provided at the front end of the baffle 42. A protrusion 47 that cooperates with the locking block 45 to lock the second-to-last detection electrode 3 is provided on the rear side of the positioning block 46. The upper surface of the locking block 45 is parallel to the plane where the inclined plane 43 is located. During the process of the detection electrode 3 falling into the V-shaped groove 52, the upper surface of the locking block 45 overlaps with the plane where the inclined plane 43 is located, and the detection electrode 3 can slide into the V-shaped groove 52. After the lowermost detection electrode 3 slides into the V-shaped groove 52, the locking block 45 rises and cooperates with the protrusion 47 to clamp the second-to-last detection electrode 3, and the remaining detection electrodes 3 will not all fall.

[0039] As Figure 3As shown in the figure, a locking cylinder 48 for driving the lifting of the locking block 45 is provided on the baffle 42. The cylinder body end of the locking cylinder 48 is fixed on the baffle 42, and the piston rod end of the locking cylinder 48 is connected to the locking block 45 through a connecting rod. A long slot is provided on the baffle 42, and the connecting rod passes through the long slot to connect the piston rod of the cylinder 48 with the locking block 45. When performing the detection of the probing electrode, the movement of the locking block is controlled by the telescopic movement of the piston rod of the locking cylinder of the locking mechanism, and then the gap between the locking block and the positioning block is controlled, so as to control the feeding of the probing electrode. When the piston rod of the locking cylinder of the locking mechanism extends, the gap between the locking block and the positioning block decreases, and the probing electrode cannot continue to slide down through the gap. On the contrary, when the piston rod of the locking cylinder of the locking mechanism contracts, the gap increases and the probing electrode can continue to slide down.

[0040] As Figure 2 shown, a blocking mechanism 8 for guiding the probing electrode 3 to enter the position of the flipping mechanism is provided on the bracket 2.

[0041] As Figure 6 shown, the blocking mechanism 8 includes a blocking cylinder 81 provided on the bracket 2, a first blocking plate 82 and a second blocking plate 83 provided at the piston rod end of the blocking cylinder 81. The first blocking plate 82 is located above the second blocking plate 83. The blocking cylinder 81 is located between the two baffles 42. The motor of the flipping mechanism 5 is located on one side of the blocking cylinder 81, and the flipping roller 51 is located at the lower end of the second blocking plate 83. The blocking mechanism 8 is used to block the probing electrode 3 sliding down from the inclined surface of the feeding mechanism 4, so that the probing electrode 3 accurately falls into the V-shaped groove 52 of the flipping roller 51. When the probing electrode 3 to be detected starts to fall from the gap between the positioning block 46 and the locking block 45 at the lower end of the feeding mechanism, the blocking cylinder 81 drives the first blocking plate 82 and the second blocking plate 83 to move forward, so that the probing electrode 3 falls onto the upper end of the second blocking plate 83. When the V-shaped groove 52 of the flipping roller 51 rotates to the uppermost end and the probing electrode 3 falls to the test position, the blocking cylinder 81 drives the first blocking plate 82 and the second blocking plate 83 to move backward, so that the probing electrode 3 just falls into the V-shaped groove 52 of the flipping roller 51.

[0042] As Figure 2 shown, a fixing mechanism 9 for placing the radial runout of the probing electrode 3 to be detected is provided on the bracket 2.

[0043] As Figure 3As shown, the fixing mechanism 9 includes a fixing cylinder 91, a moving rod 92 arranged at the piston rod end of the fixing cylinder 91, vertical rods 93 arranged at both ends of the moving rod 92, and balls 94 arranged at the ends of the vertical rods 93. Guide plates 95 are symmetrically arranged on the bracket 2, and guide holes 96 cooperating with the ends of the moving rod 92 are arranged on the guide plates 95. The fixing cylinder 91 is located in front of the turning roller 51. By driving the fixing cylinder 91, the moving rod 92 and the vertical rods 93 can be moved back and forth, and then the balls 94 can be driven to move back and forth. The balls 94 are used to fix the measuring electrode 3 in the V-shaped groove 52 of the turning roller 51. During the detection process of the measuring electrode 3, the balls 94 on the left and right sides move to the upper end of the measuring electrode 3, so that the measuring electrode 3 will not move up and down during the detection process. After the detection of the measuring electrode 3 is completed, the fixing cylinder 91 drives the balls 94 to move outwards, and the fixing of the measuring electrode 3 is released.

[0044] As Figure 5 shown, the transfer mechanism 7 includes a V-shaped guide rail 71 arranged on the base 1, a transfer cylinder 72 arranged at the end of the V-shaped guide rail 71, a sliding block 73 arranged at the piston rod end of the transfer cylinder 72, and a sliding rod 74 arranged on the side of the sliding block 73. Columns supporting the V-shaped guide rail 71 are arranged on the base 1. The transfer mechanism 7 is located below the sliding frame 54. An inclined plate 76 is arranged on the side of the V-shaped guide rail 71, and a storage box 75 is arranged at the end of the V-shaped guide rail 71. The transfer mechanism 7 is used to transfer the detected measuring electrode 3 into the storage box 75. The detected measuring electrode 3 falls onto the inclined plate 76 through the sliding frame 54, and then slides onto the V-shaped guide rail 71 through the inclined plate 76. The measuring electrode 3 is pushed into the storage box 75 by the sliding rod 74 of the transfer mechanism to store the detected measuring electrode 3.

[0045] The specific working process is as follows:

[0046] Press the device start switch, and the measuring electrode 3 to be detected is put onto the upper end of the feeding mechanism 4 through the automatic feeding machine. The measuring electrode 3 slides down through the inclined plane 43 and is arranged evenly. After the inclined plane 43 is full of the measuring electrodes 3;

[0047] The blocking mechanism 8 and the locking block 45 operate simultaneously, so that the measuring electrode 3 at the lowermost end of the inclined plane 43 falls onto the second blocking plate 83 in the blocking mechanism 8;

[0048] The turning mechanism 5 starts to operate, and the motor drives the turning roller 51 to rotate, so that the V-shaped groove 52 rotates to the detection position, and the blocking mechanism 8 places the measuring electrode 3 into the V-shaped groove 52;

[0049] The fixing mechanism 9 starts to operate. The fixing cylinder 91 drives the ball 94 to move forward, and fixes the puncture and measurement electrode 3 in the V-shaped groove 52 through the ball 94. At this time, the puncture and measurement electrode 3 can move left and right in the V-shaped groove 52;

[0050] The detection mechanism 6 starts to operate. The displacement sensor 62 of the detection mechanism 6 pushes the puncture and measurement electrode 3 forward, so that the other end of the puncture and measurement electrode 3 contacts the fixed rod 61. The puncture and measurement electrode 3 is detected by the displacement sensor of the detection mechanism 6, and the detection data is transmitted to the computer.

[0051] After the detection is completed, the detection mechanism 6 and the fixing mechanism 9 automatically reset, and the fixing of the puncture and measurement electrode 3 is released;

[0052] The flipping mechanism 5 starts to operate. The flipping roller 51 rotates, so that the puncture and measurement electrode 3 falls from the V-shaped groove 52 into the sliding frame 54, and falls into the V-shaped guide rail 71 through the inclined plate 76 of the sliding frame 54;

[0053] The transfer cylinder 72 starts to operate. The transfer cylinder 72 drives the sliding rod 74 to push the puncture and measurement electrode 3 into the storage box 75, stores the puncture and measurement electrode 3 after the detection is completed, and completes the detection work of the puncture and measurement electrode 3.
