[0002] VCSEL is a semiconductor optoelectronic device that emits laser light in a direction perpendicular to the substrate surface. It is widely used in high-end fields such as facial recognition, 3D sensing, data center optical communication, and LiDAR. It is one of the core devices in the field of modern optoelectronic technology. VCSEL production requires dedicated molding and packaging components. VCSEL chips are extremely small in size and have narrow pin pitch. The packaging process requires precise alignment, bonding, and encapsulation protection between the chip and the substrate. With the surge in demand for VCSELs in fields such as 3D sensing and optical communication, large-scale and standardized production is required. Traditional packaging methods are inefficient and difficult to adapt to the needs of mass production. Molding and packaging components can achieve precise molding of encapsulation materials and stable fixation of devices through mold forming.
[0003] Currently, VCSEL molding packaging mainly adopts manual positioning and simple molding methods. Manual positioning packaging requires operators to manually place the VCSEL chip in a preset position on the substrate with the aid of a microscope, and then encapsulate it with a simple molding die. The positioning accuracy depends entirely on the operator's experience. In use, the product qualification rate is low, and the operation is cumbersome and inefficient, making it difficult to adapt to large-scale production. Utility Model Content

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a VCSEL molding and packaging component with moisture-proof and dust-proof functions, including a base plate 1, a shell 2 fixedly connected to the upper surface of the base plate 1, a crank handle 3 rotatably connected to the outer wall of the shell 2, a threaded rod 4 fixedly connected to the outer wall of the crank handle 3, a moving block 5 rotatably connected to the outer wall of the threaded rod 4, a protective shell 6 fixedly connected to the outer wall of the moving block 5, a motor 7 fixedly mounted on the protective shell 6, a large bevel gear 8 fixedly connected to the output end of the motor 7, a central shaft 10 fixedly connected to the inner wall of the large bevel gear 8, a small bevel gear 9 meshing with the tooth end of the large bevel gear 8, a threaded rod 11 fixedly connected to the outer wall of the small bevel gear 9, a track 13 slidably connected to the outer wall of the protective shell 6, a moving bracket 12 rotatably connected to the outer wall of the threaded rod 11, and a packaging and positioning component fixedly mounted on the upper surface of the base plate 1. Specifically, the crank handle 3 connected to the outer casing 2 is rotated, which drives the threaded rod 4 to rotate. The base plate 1 supports the outer casing 2, ensuring the stability of the outer casing 2 when supporting the crank handle 3. At the same time, the outer casing 2 protects the crank handle 3 and the threaded rod 4, ensuring that the crank handle 3 does not shift or fall off due to external factors when driving the threaded rod 4. Then, the rotation of the threaded rod 4 drives the moving block 5 to move, which in turn drives the protective casing 6 to move. The moving block 5 supports the protective casing 6, while the threaded rod 4 and the track 13 restrict and guide the protective casing 6, ensuring that the protective casing 6 always moves linearly when moving and positioning with the moving block 5, and will not shift or fall off due to excessive movement, thus affecting the packaging. When it reaches the designated position, the motor 7 fixed on the protective casing 6 is started. The large bevel gear 8 is driven to rotate, with the central shaft 10 supporting it to prevent it from falling off due to its own weight. The rotation of the large bevel gear 8 then drives the small bevel gear 9 to mesh and rotate. The protective shell 6 protects both the large and small bevel gears 8 and 9, ensuring they remain in mesh and are not affected by external factors. The rotation of the small bevel gear 9 then drives the threaded rod 11 to rotate, which in turn moves the movable bracket 12, achieving axial positioning in the x and y directions. Combined with the packaging positioning components, this not only achieves high-precision and stable positioning of the components during the packaging process, ensuring the accuracy and consistency of the molding packaging, but also improves the convenience and reliability of the packaging positioning operation, adapting to high-precision packaging requirements and ensuring the quality and production efficiency of packaged products.
[0019] Reference Figure 1 and Figure 2 The encapsulation positioning component includes a retainer 14, the outer wall of which is fixedly disposed on the upper surface of the base plate 1, and a chip 15 is fixedly connected to the upper surface of the retainer 14. Specifically, the base plate 1 provides support to the retainer 14 to ensure stability during packaging, thereby ensuring that the retainer 14 fixes the chip 15 when it is positioned, which facilitates packaging.
[0020] Reference Figure 2 and Figure 3 The outer wall of the threaded rod 4 is rotatably connected to the inner wall of the outer shell 2, the outer wall of the large bevel gear 8 is rotatably connected to the inner wall of the protective shell 6, and the outer wall of the central shaft 10 is rotatably connected to the outer wall of the moving block 5. Specifically, the rotational connection of the outer shell 2 to the threaded rod 4 makes the threaded rod 4 more stable during rotation, reducing the offset or shaking caused by external factors. The stable rotation of the large bevel gear 8 within the protective shell 6 ensures meshing transmission with the small bevel gear 9, increasing the stability during transmission. The rotational connection of the central shaft 10 to the moving block 5 provides support for the large bevel gear 8, enabling the large bevel gear 8 to maintain a stable posture during rotation.
[0021] Reference Figure 2 and Figure 3 The outer wall of the small bevel gear 9 is rotatably connected to the inner wall of the protective shell 6, the outer wall of the threaded rod 11 is rotatably connected to the inner wall of the protective shell 6, the outer wall of the track 13 is fixedly connected to the upper surface of the base plate 1, and the outer wall of the movable bracket 12 is slidably connected to the inner wall of the protective shell 6. Specifically, the small bevel gear 9 is rotated on the inner wall of the protective shell 6 to ensure meshing transmission with the large bevel gear 8, reducing offset or shaking caused by external factors. The rotational connection of the threaded rod 11 on the inner wall of the protective shell 6 ensures stability during rotation and provides drive for the movement of the movable bracket 12. The track 13 is fixed on the upper surface of the base plate 1 to provide guidance and restriction for the movement of the protective shell 6, ensuring the straightness and stability of the protective shell 6 during movement. The sliding connection of the movable bracket 12 on the inner wall of the protective shell 6 enables movement and positioning under the drive of the threaded rod 11, realizing convenient positioning during the packaging process.
[0022] Reference Figure 1 , Figure 2 and Figure 4A fixed bracket 16 is fixedly connected to the outer wall of the movable bracket 12. A second motor 17 is fixedly mounted on the fixed bracket 16. A threaded post 18 is fixedly mounted at the output end of the second motor 17. A threaded cavity 19 is rotatably connected to the outer wall of the threaded post 18. A second threaded cavity 20 is rotatably connected to the outer wall of the first threaded cavity 19. A third threaded cavity 21 is rotatably connected to the outer wall of the second threaded cavity 20. A movable cavity 22 is rotatably connected to the outer wall of the third threaded cavity 21. A fixed seat 23 is fixedly connected to the inner wall of the movable cavity 22. An encapsulator 24 is fixedly connected to the outer wall of the movable cavity 22. The outer wall of column 18 is rotatably connected to the inner wall of fixed bracket 16, and the outer wall of movable cavity 22 is rotatably connected to the inner wall of fixed bracket 16; the inner wall of movable cavity 22 is rotatably connected to the outer wall of threaded cavity one 19, the inner wall of movable cavity 22 is rotatably connected to the outer wall of threaded cavity two 20, and the inner wall of movable cavity 22 is rotatably connected to the outer wall of threaded cavity three 21; the inner wall of fixed seat 23 is rotatably connected to the outer wall of threaded cavity one 19, the inner wall of fixed seat 23 is rotatably connected to the outer wall of threaded cavity two 20, and the inner wall of fixed seat 23 is rotatably connected to the outer wall of threaded cavity three 21. Specifically, the motor 17, fixed to the inner wall of the fixed bracket 16, drives the threaded column 18 to rotate. The fixed bracket 16 supports the threaded column 18, ensuring its stable rotation and preventing deviation or shaking caused by external factors. The rotation of the threaded column 18 simultaneously drives the first threaded cavity 19, the second threaded cavity 20, and the third threaded cavity 21 to rotate. The rotation of these three cavities then drives the movement and extension of each stage of the moving cavity 22, thereby enabling the packager 24 to encapsulate the chip 15. The fixed base 23 protects, restricts, and guides the first threaded cavity 19, the second threaded cavity 20, and the third threaded cavity 21, ensuring their stable rotation. The stability of threaded cavity 19 and threaded cavity 20 when driven by threaded post 18 ensures that threaded cavity 19, threaded cavity 20 and threaded cavity 21 are always in linear motion during rotation, avoiding deviation or dislodgement caused by external factors. At the same time, the moving cavity 22 protects the fixed seat 23, threaded cavity 19, threaded cavity 20 and threaded cavity 21, ensuring that the internal thread transmission is not affected by external factors and is not deviated or dislodged. This not only achieves stable operation of chip 15 molding and packaging and ensures the consistency and sealing of the packaging process, but also improves the reliability and adaptability of the packaging operation, meets the packaging requirements of VCSEL components, and ensures the quality and production efficiency of packaged products.
[0023] Working principle: When positioning is required for packaging, the crank handle 3 is rotated, which drives the threaded rod 4 to rotate. The rotation of the threaded rod 4 then drives the moving block 5 to move, which in turn drives the protective shell 6 to move. When it reaches the designated position, the motor 7 is started to drive the large bevel gear 8 to rotate. The rotation of the large bevel gear 8 then drives the small bevel gear 9 to mesh and rotate. The rotation of the small bevel gear 9 then drives the threaded rod 11 to rotate, which in turn drives the moving bracket 12 to move. This achieves axial positioning in the x and y directions. Combined with the packaging positioning components, this not only achieves high-precision and stable positioning of the components during the packaging process, ensuring the accuracy and consistency of the molding packaging, but also improves the convenience and reliability of the packaging positioning operation, adapts to high-precision packaging requirements, and ensures the quality of packaged products and production efficiency. When encapsulation is required, the second motor 17 drives the threaded column 18 to rotate. The rotation of the threaded column 18 simultaneously drives the first threaded cavity 19, the second threaded cavity 20, and the third threaded cavity 21 to rotate. The rotation of the first threaded cavity 19, the second threaded cavity 20, and the third threaded cavity 21 then drives the movement and extension of each stage of the moving cavity 22, thereby driving the encapsulator 24 to encapsulate the chip 15. This not only achieves stable operation of the chip 15 molding encapsulation and ensures the consistency and sealing of the encapsulation process, but also improves the reliability and adaptability of the encapsulation operation, meets the encapsulation requirements of VCSEL components, and ensures the quality of the encapsulated products and production efficiency. In other words, this packaging component not only achieves high-precision and stable positioning of components during the packaging process, ensuring the accuracy and consistency of molding packaging and improving the convenience and reliability of packaging positioning operations, adapting to high-precision packaging requirements, and ensuring the quality and production efficiency of packaged products, but also achieves stable operation of chip 15 molding packaging, ensuring the consistency and sealing of packaging processes, and improving the reliability and adaptability of packaging operations, meeting the packaging requirements of VCSEL components, and ensuring the quality and production efficiency of packaged products.
