[0002] In the production of transistors, especially high-power transistors in metal packages, sealing is a crucial process. Its purpose is to permanently seal the metal cover plate to the metal base containing the chip through high-temperature brazing, so as to protect the internal chip from external moisture, impurities, etc., and ensure the long-term reliability of the transistor.

[0003] In traditional transistor manufacturing sealing machines, a metal base is typically placed in a mounting hole, and then a cover plate is placed on top of the metal base. With the help of a heating head, the component in the mounting hole is hot-pressed to complete the sealing process.

[0004] However, after the sealing welding is completed, operators often need to use tweezers or other tools to pry the workpiece. The prying action is cumbersome, time-consuming, and reduces work efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

The tops of the two sliders are fixedly connected to the same support frame. A placement groove is formed at the center of the upper surface of the support frame. A top plate is placed in the placement groove. Multiple top blocks are fixedly connected to the upper surface of the top plate. A placement plate is also provided in the placement groove, with both sides of the placement plate fixedly connected to the placement groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 A sealing and welding machine for transistor production includes a frame 1, a fixed frame 3 fixed to the top of the frame 1 by bolts, a sliding groove 4 on both sides of the fixed frame 3, a slide 6 slidably connected in each of the two sliding grooves 4, a housing 19 fixed between the two slides 6 by bolts, a hydraulic cylinder 5 fixed to the top of the fixed frame 3 by bolts, and one end of the hydraulic cylinder 5 fixed to the housing 19, and the hydraulic cylinder 5 connected to a hydraulic control system;

[0026] The top of the frame 1 is fixed with two slide rails 2 by bolts. Each slide rail 2 is slidably connected with a slider 9. The top of the two sliders 9 is fixed with a support frame 8 by bolts. A placement groove is opened at the center of the upper surface of the support frame 8. A top plate 14 is placed in the placement groove. Multiple top blocks 17 are fixedly connected to the upper surface of the top plate 14. A placement plate 13 is also provided in the placement groove. Multiple fixing holes 12 are opened on the upper surface of the placement plate 13, and the top blocks 17 can pass through the fixing holes 12. The two sides of the placement plate 13 are fixedly connected to the placement groove.

[0027] An L-shaped rod 15 is fixed to the bottom of the top plate 14 by bolts. A through groove 16 is provided on one side of the support frame 8, and the L-shaped rod 15 slides in the through groove 16.

[0028] During installation, first install the top plate 14 on the support frame 8, then align the fixing holes 12 of the placement plate 13 with the top block 17, and finally weld the placement plate 13 to both sides of the placement groove.

[0029] In use, the operator pulls the L-shaped rod 15, causing the top plate 14 to slide along the bottom of the placement plate 13. The top block 17 lifts the workpiece in the fixing hole 12, making it easy to remove the processed transistor without the need for tweezers or other tools. This simplifies the material handling process, effectively shortens the operation time, and significantly improves work efficiency.

[0030] like Figure 3 As shown, the top of the frame 1 is provided with a pressurizing device for pressing the transistor. The pressurizing device includes multiple pressure heads 20, which are welded to one side of the housing 19. A heat insulation pad 18 is fixed to the top of the housing 19 by bolts. The heat insulation pad 18 is located at the connection between the hydraulic cylinder 5 and the housing 19. The heat insulation pad 18 can reduce the heat conduction to the hydraulic cylinder 5. In use, the hydraulic cylinder 5 drives the housing 19 to move down along the slide 4, and the pressure head 20 contacts the workpiece and applies pressure.

[0031] In this utility model, a heating assembly for sealing welding is provided on one side of the housing 19. The heating assembly includes multiple heating tubes 21. A cavity is opened inside the housing 19. The multiple heating tubes 21 are all fixed in the cavity by bolts. A controller 22 is fixed on one side of the housing 19 by bolts. The heating tubes 21 are electrically connected to the controller 22. A spring wire 7 is provided on one side of the controller 22. When in use, the controller 22 is model XM-TD200. The controller 22 controls the heating tubes 21 to work and heat the pressure head 20 to complete the sealing welding operation.

[0032] Especially such as Figure 3 As shown, the top of the frame 1 has multiple through holes, and a fan 11 is fixed in each of the multiple through holes by bolts. A partition 10 is fixed in the top of the through holes by bolts. The fan 11 blows air upward through the through holes, and the airflow is evenly applied to the workpiece through the partition 10 to accelerate its cooling.

[0033] A self-locking cylinder 23 is fixed to the top of the frame 1 by bolts, and one end of the self-locking cylinder 23 is fixed to the support frame 8. When the self-locking cylinder 23 is activated, it pushes the support frame 8 to move along the slide rail 2, so that the workpiece on the placement plate 13 is accurately aligned with the bottom of the pressure head 20.

[0034] Working principle: The operator places the transistor workpiece to be sealed in the fixing hole 12, and starts the self-locking cylinder 23. The self-locking cylinder 23 pushes the support frame 8 to move along the slide rail 2, so that the workpiece on the placement plate 13 is accurately aligned with the pressure head 20. Then the hydraulic cylinder 5 drives the housing 19 to move down along the slide groove 4. The pressure head 20 contacts the workpiece and applies pressure. At the same time, the controller 22 controls the heating tube 21 to work, heating the pressure head 20 to complete the sealing operation.

[0035] After the sealing is completed, the self-locking cylinder 23 pushes the support frame 8 to move along the slide rail 2, so that it comes above the fan 11. The fan 11 switch is turned on, and the fan 11 blows air upward through the through hole. The airflow is evenly applied to the workpiece through the partition 10 to accelerate its cooling.

[0036] After cooling is complete, the hydraulic cylinder 5 drives the housing 19 to reset. The operator pulls the L-shaped rod 15 to make the top plate 14 slide along the bottom of the placement plate 13. The top block 17 lifts the workpiece in the fixing hole 12, and the processed transistor can be easily taken out.

[0037] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
