Description

Technical Field

[0001] The utility model relates to the technical field of laser diode production, in particular to a positioning device for laser diode production. Background Technique

[0002] The basic principle of a laser diode is to utilize the light generated when electrons and holes recombine, and form laser through the reflection and amplification of a resonant cavity. When an electric current passes through a pn junction composed of a p-type semiconductor and an n-type semiconductor, electrons are injected from the n region into the p region, and holes are injected from the p region into the n region. These non-equilibrium electrons and holes recombine near the pn junction, emitting photons. These photons are reflected and amplified in the resonant cavity, and finally form laser.

[0003] During the production process of a laser diode, precise cutting, welding, or assembly operations need to be performed on semiconductor materials. At this time, a fixing device is required during production. The fixing device can ensure that these operations are carried out at precise positions, avoiding production errors caused by position deviation. The device generally includes a mounting frame, a clamping assembly, and a driving assembly. Usually, the clamping assembly is mounted on the mounting frame. The clamping assembly includes: two threaded rods and two clamping plates. The driving assembly is generally a transmission gear set. The two threaded rods are driven to rotate through the transmission gear set, and the two threaded rods drive the two clamping plates to move towards the relatively close direction, so that the two clamping plates clamp and fix the laser diode in the middle position. At this time, the fixing during the production of the laser diode is completed. However, during the use of this fixing device, since the two clamping plates only provide pressure on the left and right sides to fix the laser diode, many operations need to be performed on the laser diode itself during the production process of the laser diode. Therefore, during the production process, when contacting the laser diode due to production operations, the laser diode may be displaced due to only applying pressure on the left and right sides of the laser diode, which may cause damage to the laser diode and result in waste of materials.

[0004] Therefore, it is necessary to provide a new positioning device for laser diode production to solve the above technical problems. Content of the Utility Model

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0023] In the specific implementation process, as Figures 1-5 shown, the positioning device for laser diode production provided by the present utility model includes: a fixing device and two auxiliary clamping devices. The two auxiliary clamping devices are both installed inside the fixing device, and the two auxiliary clamping devices are arranged oppositely. The fixing device is used to provide a clamping force in the left and right directions for the laser diode;

[0024] The auxiliary clamping device includes: a first clamping plate 1, a first threaded rod 2, a movable rod 3 and a movable block 4. One side of the first clamping plate 1 is fixedly connected to one end of the movable rod 3. The first clamping plate 1 is arc-shaped. The end of the movable rod 3 away from the first clamping plate 1 is installed inside the fixing device, and the movable rod 3 is fixedly connected to one end of the movable block 4. One end of the first threaded rod 2 penetrates through the movable block 4. The first threaded rod 2 is movably arranged on one side of the fixing device. The first threaded rod 2 is threadedly connected to the movable block 4. A rotating rod 5 is provided on the side of the first threaded rod 2 extending out of the fixing device. The above-mentioned first threaded rod 2 is movably connected to the fixing device and threadedly connected to the movable block 4, so that during use, when the threaded rod 2 rotates, it will only drive the movable block 4 to move linearly along the threaded rod 2. The arc-shaped first clamping plate 1 enables it to better fit the outer surface of the laser diode during use, making the clamping more stable. The setting of the rotating rod 5 enables the first threaded rod 2 to be rotated more conveniently during use. In the actual use process, when clamping some laser diodes with irregular shapes, the movements of the two first clamping plates 1 can be carried out separately at this time, so as to provide better clamping force for these laser diodes with irregular shapes.

[0025] The fixing device includes: a fixing block 6, a driving component and two fixing components. The fixing block 6 is in a Y shape. The protruding parts on both sides of the fixing block 6 are rectangular. Installation grooves 7 are provided on the inner walls of the protruding parts on both sides of the fixing block 6. Moving grooves 8 are provided at the upper ends of the two installation grooves 7. One ends of the two movable rods 3 and the two movable blocks 4 are respectively installed in the installation grooves 7. The two first threaded rods 2 are respectively installed in the moving grooves 8. The two fixing components are respectively installed on both sides of the fixing block 6. The two fixing components are arranged oppositely. The two fixing components are both installed inside the driving component. The driving component is installed outside the fixing block 6.

[0026] The fixing component includes: a fixing plate 9, a fixing rod 10 and a second clamping plate 11. One side of the second clamping plate 11 is fixedly connected to one end of the fixing rod 10. The end of the fixing rod 10 away from the second clamping plate 11 is fixedly connected to the fixing plate 9. The fixing plate 9 is installed inside the driving component, and the driving component penetrates through the fixing plate 9. The two first clamping plates 1 and the two second clamping plates 11 are all made of flexible materials. The above-mentioned two first clamping plates 1 and the two second clamping plates 11 are made of flexible materials, so that the laser diode can be better protected during the clamping and fixing process and will not be damaged due to excessive clamping force.

[0027] The driving assembly includes: a transmission gear set, a mounting frame 12, a second threaded rod 13, and a third threaded rod 14. One ends of the second threaded rod 13 and the third threaded rod 14 are respectively fixedly connected to both sides of the transmission gear. The ends of the second threaded rod 13 and the third threaded rod 14 far from the transmission gear set respectively penetrate through two fixing plates 9 and are threadedly connected to both fixing plates 9. The mounting frame 12 is installed on the outer sides of the second threaded rod 13 and the third threaded rod 14. The outer side wall of the fixing plate 9 is in contact with the inner side wall of the mounting frame 12. The ends of the second threaded rod 13 and the third threaded rod 14 far from the transmission gear set both penetrate through the inner wall of the mounting frame 12 and are movably connected to the mounting frame 12. The contact between the outer side wall of the fixing plate 9 and the inner side wall of the mounting frame 12 causes that when the second threaded rod 13 and the third threaded rod 14 rotate, the two fixing plates 9 will respectively move linearly along the second threaded rod and the third threaded rod due to the restriction of the mounting frame 12.

[0028] The transmission gear set includes: a first bevel gear 15, a second bevel gear 16, and a third bevel gear 17. The second bevel gear 16 and the third bevel gear 17 are arranged oppositely. One side of the second bevel gear 16 is fixedly connected to one end of the second threaded rod 13. One side of the third bevel gear 17 is fixedly connected to one end of the third threaded rod 14. The first bevel gear 15 is located on the same side of the second bevel gear 16 and the third bevel gear 17, and the first bevel gear 15 is respectively meshed with the second bevel gear 16 and the third spur gear. A rotating column 18 is provided on the side of the first bevel gear 15 far from the second bevel gear 16. The end of the rotating column 18 far from the first bevel gear 15 penetrates through the mounting frame 12.

[0029] The working principle provided by the present utility model is as follows: In the specific use process, the laser diode is placed on the fixed block 6. By rotating the rotating column 18, the first bevel gear 15 is driven to rotate. The first bevel gear 15 drives the second bevel gear 16 and the third bevel gear 17 to rotate in opposite directions. At this time, the second threaded rod 13 and the third threaded rod 14 are also driven to rotate in opposite directions. At this time, the two fixing plates 9 move relatively closer on the second bevel gear 16 and the third bevel gear 17 respectively. When the two second clamping plates 11 fix the laser diode, rotate the two rotating rods 5 at this time. At this time, the limiting block moves linearly on the first threaded rod 2. At this time, the two first clamping plates 1 make a linear motion of moving relatively closer. When the two first clamping plates 1 clamp and fix the laser diode, the clamping and fixing of the laser diode are completed. The device is simple to operate. During use, it can provide a clamping force in the left-right direction for the laser diode and at the same time provide a clamping force in the front-back direction for the laser diode. During the production of the laser diode, it provides a clamping force in four directions for the laser diode. And when adjusting the distance between the first clamping plates 1, the movements of the two first clamping plates 1 are separate and independently arranged. This enables a good clamping effect to be achieved for some irregular laser diodes, making the clamping more stable and not easy to fall off, protecting the safety of the laser diode during the production process and avoiding material waste caused by unstable clamping.

[0030] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here too much.

[0031] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
