[0001] The utility model relates to the field of ceramic-metal sealing, in particular to a ceramic-metal hot-pressing sealing tool. Background Art

[0002] Ceramic and metal connectors are widely used in new energy, electronics, semiconductor packaging, and IGBT modules. These products primarily include ceramic-metal structural components. Due to increasing market demand and the continuous emergence of new materials, the sealing process for ceramic and metal components of corresponding shapes is crucial, while also ensuring high strength, airtightness, and reliability. However, existing technologies require the use of a pressure setting tool to set the initial pressure each time metal and ceramic are sealed, which is a cumbersome operation. Furthermore, the clamps used for installation and removal are inconvenient, resulting in low hot pressing efficiency. Utility Model Content

[0003] In order to solve the technical problem that each time metal and ceramic are sealed, the initial pressure of the pressure setting tool needs to be used, resulting in low hot pressing efficiency, an object of the present utility model is to provide a hot pressing sealing tool for ceramics and metals.

[0004] To achieve the above-mentioned purpose, an embodiment of the present invention provides a ceramic metal hot pressing sealing tool, including a sleeve with a first accommodating cavity provided therein; an adjusting component arranged inside the first accommodating cavity, the top of the adjusting component passing through the upper surface of the sleeve; a sealing component arranged inside the first accommodating cavity, the lower end of the sealing component passing through the lower surface of the sleeve; a pressure-bearing component, the upper end of which is connected to the adjusting component and the lower end of which is connected to the sealing component; a supporting component arranged below the sleeve, the lower end of the sealing component extending into the interior of the supporting component.

[0005] By providing an adjusting component inside the first accommodating cavity and providing a sealing component located in the first accommodating cavity below the adjusting component, pressure can be applied to the pressure-bearing component through the adjusting component, and the pressure-bearing component then applies pressure to the sealing component, so that the sealing components can be connected into a whole. When a group of sealing components are connected, the operator no longer needs to adjust the pressure of the adjusting component, and can directly apply pressure to the pressure-bearing component, thereby reducing the operating difficulty of the operator and improving the hot pressing efficiency. By providing a supporting component below the sleeve, the lower end of the sealing component can be prevented from contacting the ground, and at the same time, it can also have a positioning effect on the sealing component.

[0006] In addition, the punching die for the glass powder ring in the above embodiment provided by the present invention may also have the following additional technical features:

[0007] In the above technical solution, the sleeve includes a lower sleeve with a first end face at the upper end; an upper sleeve with a lower end slidably connected to the interior of the lower sleeve, and a second end face is provided on the side wall of the upper sleeve, and threaded holes are provided corresponding to the second end face and the first end face.

[0008] By sliding the lower end of the upper sleeve into the interior of the lower sleeve, the sealing of the upper sleeve and the lower sleeve can be ensured. In addition, by providing a first end face at the upper end of the lower sleeve and a second end face on the side wall of the upper sleeve, the first end face and the second end face are connected to the threaded hole by screws, thereby further improving the sealing of the upper sleeve and the lower sleeve, while also ensuring the stability of the upper sleeve and the lower sleeve.

The first screw is threadedly connected to the top of the upper sleeve. By rotating the first screw, the first screw pushes the first sleeve downward, causing the disc spring to contract. The contraction of the disc spring generates pressure on the sealing assembly. During use, the pressure of the disc spring can be set by adjusting the screw once, and the operation process is simple.

[0011] In the above technical solution, the sealing assembly includes: a first metal part, placed on the inner bottom of the lower sleeve, and a groove is provided on the upper surface of the first metal part; a ceramic part, including a head and a tail, the head is provided at the bottom of the groove, an annular groove is provided on the upper surface of the head, and the tail passes through the bottom of the groove and the lower surface of the lower sleeve; a second metal part, the lower end of which is provided inside the annular groove, and a second shoulder is provided on the side wall of the second metal part, which is located on the upper surface of the ceramic part; a sealing ring is provided between the bottom of the groove and the lower surface of the head, and a sealing ring is provided between the upper surface of the head and the lower surface of the second shoulder.

[0012] Sealing rings are provided between the bottom of the groove and the lower surface of the head, as well as between the upper surface of the head and the lower surface of the second shoulder.

The liquid solder and the metal diffuse and dissolve with each other, and after condensation, a brazing head is formed. Then, the first metal, the second metal part and the ceramic part can be connected into a whole through the sealing ring.

[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] Refer to the following Figures 1 to 5 A ceramic-metal hot-pressing sealing tool is described according to some embodiments of the present invention.

[0037] like Figures 1 to 5 As shown, an embodiment of the present invention provides a ceramic-metal hot-pressing sealing tool, comprising a sleeve, an adjusting assembly, a sealing assembly, a pressure-bearing assembly and a supporting group.

[0038] Specifically, a first accommodating cavity 1 is provided inside the sleeve; an adjusting component is provided inside the first accommodating cavity 1, and the top of the adjusting component passes through the upper surface of the sleeve; a sealing component is provided inside the first accommodating cavity 1, and the lower end of the sealing component passes through the lower surface of the sleeve; a pressure-bearing component, the upper end of which is connected to the adjusting component and the lower end of which is connected to the sealing component; a supporting component is provided below the sleeve, and the lower end of the sealing component extends into the interior of the supporting component.

[0039] When the sealing assembly needs to be hot-pressed, the sleeve is first placed on the upper surface of the supporting assembly, and then the sealing assembly is placed in the bottom of the first accommodating cavity 1. The lower end of the sealing assembly passes through the bottom of the sleeve and extends into the interior of the supporting assembly. Then the pressure-bearing assembly is placed on the sealing assembly, and then the adjusting assembly is placed in the sleeve, and the bottom of the adjusting assembly is against the upper surface of the pressure-bearing assembly. Then the sleeve is sealed, and then the pressure of the adjusting assembly is adjusted. The pressure generated by the adjusting assembly acts on the pressure-bearing assembly, and the pressure-bearing assembly then acts on the sealing assembly. Then the entire device is placed in the high-temperature container, and the sealing assembly is completed. When the next cycle is carried out, since there is no need to operate the adjustment component, it is only necessary to remove the sleeve and put another sealing component into the sleeve, and then seal the sleeve again. Compared with the prior art which requires pressure adjustment every time, the present invention only requires one pressure adjustment, which is easier to operate. In addition, the prior art adopts a clamp type connection, and the internal hot pressing structure is relatively complex, which is not convenient for installation and disassembly. However, the present application only requires connecting the workpieces that need to be hot pressed together, putting them into the sleeve, and then transferring the pressure through the pressure-bearing component. The internal structure is relatively simple, and disassembly and installation are more convenient.

[0040] like Figures 1 to 4 As shown, in one embodiment of the present utility model, the sleeve includes a lower sleeve 2, the upper end of which is provided with a first end face 4; an upper sleeve 3, the lower end of which is slidably connected to the interior of the lower sleeve 2, and the side wall of the upper sleeve 3 is provided with a second end face 5, and the second end face 5 and the first end face 4 are correspondingly provided with threaded holes 6.

[0041] When it is necessary to connect the upper sleeve 3 and the lower sleeve 2 to each other, the lower end of the upper sleeve 3 is extended into the interior of the lower sleeve 2, the outer wall of the upper sleeve 3 contacts the inner wall of the lower sleeve 2, and the upper sleeve 3 and the lower sleeve 2 are slidably connected, which can improve the sealing of the upper sleeve 3 and the lower sleeve 2. In addition, by providing a first end face 4 at the upper end of the lower sleeve 2, a second end face 5 is provided on the side wall of the upper sleeve 3, and threaded holes 6 are correspondingly provided on the first end face 4 and the second end face 5. The screws are threadedly connected with the threaded holes 6 corresponding to each other, and the first end face 4 and the second end face 5 can be connected until the first end face 4 and the second end face 5 contact each other and are locked with each other. The close contact between the first end face 4 and the second end face 5 can further improve the sealing of the upper sleeve 3 and the lower sleeve 2, while also ensuring the stability of the upper sleeve 3 and the lower sleeve 2.

[0042] like Figure 1 and Figure 3As shown, in one embodiment of the present utility model, the adjustment assembly includes a first sleeve 7, which is slidably connected to the upper sleeve 3; a second sleeve 8, which is fixedly connected to the lower surface of the first sleeve 7, the second sleeve 8 is coaxially arranged with the first sleeve 7, and the outer diameter of the second sleeve 8 is smaller than the outer diameter of the first sleeve 7; a disc spring 9, which is sleeved on the outside of the second sleeve 8; a first screw 10, which is threadedly connected to the upper surface of the upper sleeve 3; a pressure head 11, which is sleeved on the second sleeve 8, and the pressure head 11 is arranged at the bottom of the disc spring 9, and a first shoulder 12 is provided at the top of the side wall of the pressure head 11, and the first shoulder 12 is slidably connected to the inner wall of the upper sleeve 3; a gasket 13, which is arranged on the lower surface of the pressure head 11; a second screw 14, which passes through the gasket 13 and is threadedly connected to the second sleeve 8.

[0043] When it is necessary to install the adjustment component, first put the first sleeve 7 and the second sleeve 8 into the interior of the upper sleeve 3, and the second sleeve 8 is located on the lower surface of the first sleeve 7. The first sleeve 7 and the second sleeve 8 are integrally formed, which can reduce the difficulty of separately processing the first sleeve 7 and the second sleeve 8. In addition, the integral formation of the first sleeve 7 and the second sleeve 8 can improve the structural strength of the first sleeve 7 and the second sleeve 8. The first sleeve 7 and the second sleeve 8 are coaxially arranged, and the diameter of the second sleeve 8 is smaller than the diameter of the first sleeve 7. The outer wall of the first sleeve 7 contacts the inner wall of the upper sleeve 3 and is slidably connected to the inner wall of the upper sleeve 3 to prevent the first sleeve 7 from shaking in the horizontal direction. The diameter of the second sleeve 8 is smaller than the diameter of the first sleeve 7, thereby making the first sleeve 7 There is a gap between the second sleeve 8 and the inner wall of the upper sleeve 3, which makes it easy to sleeve a disc spring 9 on the outer wall of the second sleeve. The outer wall of the disc spring 9 contacts the inner wall of the upper sleeve 3, which can prevent the disc spring 9 from shaking in the horizontal direction. When the disc spring 9 is installed, a pressure head 11 is sleeved on the bottom of the second sleeve. The pressure head 11 is a circular ring structure. The inner wall of the pressure head 11 is in contact and sliding connection with the outer wall of the second sleeve 8. A gasket 13 is provided at the bottom of the pressure head 11. The gasket 13 is coaxially arranged with the first sleeve 7 and the second sleeve 8. The diameter of the gasket 13 is larger than the inner diameter of the pressure head 11, which can ensure that the gasket 13 has a limiting effect on the pressure head 11. By using a second screw 14 to penetrate the center of the gasket 13 and threadedly connected to the second sleeve 8, through The second screw 14 can connect the first sleeve 7, the second sleeve 8, the disc spring 9, the pressure head 11, the first shoulder 12 and the gasket 13 into a whole. When it is necessary to set the initial pressure for the entire device, the operator can rotate the first screw 10 threadedly connected to the top of the upper sleeve 3. The first screw 10 gradually extends into the interior of the upper sleeve and gradually presses down the first sleeve 7. The first sleeve 7 presses down the disc spring 9. Since the position of the sealing component will not change during installation, and the position of the pressure-bearing component will not change, the top of the pressure-bearing component is against the first shoulder 12, so that the position of the pressure head 11 and the first shoulder 12 will not change. Therefore, when the first screw 10 applies pressure to the first sleeve 7, the first sleeve 7, the second sleeve 8, the gasket 13 and the first sleeve 7 are pressed together. The two screws 14 move downward together, and the first sleeve 7 compresses the disc spring 9. The pressure generated by the disc spring 9 acts on the pressure head 11 and the first shoulder 12, and then the pressure generated by the first shoulder 12 and the pressure head 11 acts on the pressure-bearing component. The pressure-bearing component then generates pressure on the sealing component. The first screw 10 is continuously adjusted until the pressure generated by the disc spring 9 meets the pressure of the hot pressing of the sealing component. Then, the adjustment of the first screw 10 is stopped, and the entire device is placed inside the hot pressing equipment to hot press the sealing component. In the above process, after the operator completes the first hot pressing, he only needs to take out the hot-pressed sealing component and replace it with a new sealing component. There is no need to adjust the adjustment component again, which greatly simplifies the operating steps and improves the hot pressing efficiency of the sealing component.

[0044] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the sealing assembly includes: a first metal part 15, placed on the inner bottom of the lower sleeve 2, and a groove 16 is provided on the upper surface of the first metal part 15; a ceramic part 17, including a head 18 and a tail 19, the head 18 is arranged at the bottom of the groove 16, and an annular groove 20 is provided on the upper surface of the head 18, and the tail 19 passes through the bottom of the groove 16 and the lower surface of the lower sleeve 2; a second metal part 21, the lower end of which is arranged inside the annular groove 20, and a second shoulder 22 is provided on the side wall of the second metal part 21, which is located on the upper surface of the ceramic part 17; a sealing ring is provided between the bottom of the groove 16 and the lower surface of the head 18, and a sealing ring is provided between the upper surface of the head 18 and the lower surface of the second shoulder 22.

[0045] According to the actual use requirements of the first metal member 15, the second metal member 21 and the ceramic member 17, the first metal member 15 needs to be placed in the inner bottom of the lower sleeve 2, and a gap is left between the first metal member 15 and the inner wall of the lower sleeve 2. A plurality of step surfaces are provided on the side wall of the first metal member 15, and a groove 16 is provided inside the first metal member 15. A ceramic member 17 is provided inside the groove 16. The ceramic member 17 includes a head 18 and a tail 19.

The outer wall of the second metal part 21 is provided with a second shoulder 22. The lower surface of the second shoulder 22 contacts the upper surface of the ceramic part 17. The upper end of the pressure-bearing component is against the lower surface of the first shoulder 12, and the lower end is against the upper surface of the second shoulder 22. Through the mutual cooperation of the pressure-bearing component, the first shoulder 12 and the second shoulder 22, the adjusting component applies pressure to the sealing component. A sealing ring is provided between the bottom of the groove 16 and the lower surface of the head 18, and a sealing ring is also provided between the upper surface of the head 18 and the lower surface of the second shoulder 22. The sealing ring adopts high-temperature lead solder, which melts in a high-temperature and high-pressure environment and is sucked in by capillary action, filling the space between the bottom of the groove 16 and the lower surface of the head 18, as well as between the upper surface of the head 18 and the lower surface of the second shoulder 22. The liquid solder and the metal diffuse and dissolve with each other, and form a brazing head after condensation. Then, the first metal, the second metal part 21 and the ceramic part 17 can be connected into a whole through the sealing ring.

[0046] It should be noted that the above descriptions of the structures of the ceramic part 17, the first metal part 15 and the second metal part 21 are all existing technologies and are not the innovations of the present invention. The structural descriptions of the first metal part 15, the second metal part 21 and the ceramic part 17 are mainly used to introduce the specific position of the sealing ring. The main design point is that sealing rings are provided on the connecting surfaces in the horizontal direction between the first metal part 15 and the ceramic part 17, and on the connecting surfaces in the horizontal direction between the second metal part 21 and the ceramic part 17. The sealing rings can connect the first metal part 15, the second metal part 21 and the ceramic part 17 into a whole under a hot pressing environment.

[0048] A lower pressure ring 23 is provided between the first shoulder 12 and the second shoulder 22, so that the adjustment component can apply pressure to the sealing component through the lower pressure ring 23. At the same time, the lower pressure ring 23 is loosely matched with the second metal part 21, and the second metal part 21 can be positioned through the lower pressure ring 23. The middle part of the lower pressure ring 23 is a hollow structure, which can ensure that the gasket 13 is not blocked when moving downward.
