Description

Technical Field

[0001] This utility model relates to the field of sodium-nickel battery technology, specifically a paste-coating and fixing fixture for sodium-nickel battery TCB components. Background Technology

[0002] The sodium-nickel battery TCB module is composed of an α-alumina ceramic ring, an inner nickel ring, and an outer nickel ring, which are bonded together by a hot-pressing bonding process. By coating the surface of the α-alumina ceramic ring of the TCB module with glass paste, and then assembling it with β″-Al2O3 solid electrolyte through high-temperature sealing, the resulting connector plays a key role in sealing the battery and isolating the positive and negative electrodes.

[0003] During the paste application process for sodium-nickel battery TCB modules, there are specific requirements for the fixed position of the TCB modules. Deviations in position can lead to uneven paste application and overflow. Currently, two common methods for fixing sodium-nickel battery TCB modules during paste application are increasing the height of the tooling edge and using spring clamps. However, both methods have certain drawbacks in practical use. With increasing the height of the tooling edge, the glass paste can adhere to the tooling edge during application, causing paste defects. With the spring clamp method, due to the small clamping area, the TCB modules may loosen and bounce during handling or paste application due to vibration, potentially causing abnormalities such as the paste application machine needle collision, thus affecting production efficiency.

[0004] Based on the above analysis, this solution designs a novel paste-coating and fixing fixture for sodium-nickel battery TCB modules. Utility Model Content

[0005] The purpose of this utility model is to provide a compact fixture that facilitates the installation and fixation of the TCB component 40, thereby addressing at least one deficiency in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A paste-coating and fixing fixture for a sodium-nickel battery TCB module includes a base plate and a plurality of edge guards fixed on the base plate. It also includes magnetic positioning seats, the number of which corresponds to the number of edge guards, and the magnetic positioning seats are disposed inside the edge guards to attract and fix the TCB module.

[0007] As a preferred embodiment: the edge guard is composed of two edge guards that are perpendicularly joined at their ends. The bottom of the edge guard at the right angle position is provided with a countersunk groove. One end of the magnetic positioning seat is engaged with the countersunk groove, and the other end has an inner arc surface or ring that is adapted to the structure of the TCB component and extends to the inner side of the edge guard.

[0008] As a preferred embodiment, the base plate is provided with a limiting groove and a threaded hole, and at the same time, positioning holes are provided on the two flanges respectively. At least one of the flanges and the magnetic positioning seat can be embedded in the limiting groove and fixed by bolts in cooperation with the threaded hole and the positioning hole.

[0009] As a preferred embodiment, the magnetic positioning seat is fitted into the countersunk groove at one end with a right-angle structure or an outwardly convex arc surface structure.

[0010] As a preferred embodiment, after fixing, the TCB component has a gap of 0.5-1mm between the inner arc surface and the upper plane of the magnetic positioning seat.

[0011] As a preferred embodiment, the base plate and the edge guard are made of metal substrate, and a wear-resistant layer is coated on the surface of the metal substrate.

[0012] As a preferred embodiment, the height of the edge guard is less than the height of the TCB component.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This solution's paste-applying and fixing fixture abandons the traditional spring clamping method and instead uses the magnetic attraction provided by the magnetic positioning seat to fix the TCB assembly. This solution places the magnetic positioning seat on one end of the inner side of the retaining member, which can simultaneously provide axial and radial attraction to the TCB assembly. On the one hand, it significantly improves the stability of the TCB assembly fixing, and on the other hand, it facilitates the quick placement and removal of the TCB assembly on the fixture, effectively improving work efficiency. It can be seen that this solution's sodium-nickel battery TCB assembly paste-applying and fixing fixture has a compact structure and is easy to use, solving the shortcomings of the existing spring clamping method where the TCB assembly is easy to loosen and bounce up.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0027] This embodiment provides a paste-applying and fixing fixture for a sodium-nickel battery TCB module. The fixture includes a base plate 10, multiple edge members 20 disposed on the base plate 10, and a magnetic positioning seat 30. The edge members 20 are equidistantly arranged on the base plate 10, and the inner dimension of each edge member 20 is greater than or equal to the dimension of the TCB module 40, ensuring that the TCB module 40 can be placed inside the edge member 20. The magnetic positioning seat 30 has strong magnetism and is disposed inside the edge member 20. It can provide at least an axial magnetic attraction force to the TCB module 40, using this axial magnetic attraction force to limit and fix the TCB module 40. Figure 1-3 The diagram shown is a structural schematic of the fixed tooling provided in this embodiment from various angles.

[0028] Specifically, this embodiment abandons the traditional spring clamping method and uses the magnetic attraction provided by the magnetic positioning seat 30 to limit and fix the TCB component 40. It can be understood that, depending on the height of the edge member 20, the TCB component 40 can be limited and fixed in a designated area of ​​the edge member 20. For example, when the height of the edge member 20 is greater than or equal to the maximum height of the TCB component 40, it is preferable that the TCB component 40 is magnetically limited and fixed in the central area of ​​the edge member 20, increasing the distance between the TCB component 40 and the edge member 20. This solves the problem that when the TCB component 40 is close to the edge member 20, the glass paste tends to adhere to the edge member 20, causing coating defects. In this embodiment, it is preferable that the height of the edge member 20 is less than the height of the TCB component 40. In this structure, the TCB component 40 is magnetically limited and fixed in a position close to the edge member 20. Figure 6-7 As shown.

[0029] Compared to existing methods, this embodiment integrates the magnetic positioning seat 30 onto the tooling, improving the compactness of the tooling structure. In addition, the use of magnetic attraction to limit and fix the TCB component 40 can significantly improve the stability of the TCB component 40 and facilitate the quick placement and removal of the TCB component 40 on the tooling, effectively improving work efficiency.

[0030] As a preferred embodiment, the edge guard 20 includes two edge guards that are perpendicularly joined at their ends, such as... Figure 4a As shown, the retaining edge 20 is a right-angled structure composed of a first retaining edge 21 and a second retaining edge 22. The two retaining edges are of equal length and the right angle formed is the inner angle of the retaining edge 20. It can be understood that the size of the inner area formed by the first retaining edge 21 and the second retaining edge 22 should be larger than the size of the TCB assembly 40 to ensure that the TCB assembly 40 can be accommodated in the inner area. The bottom of the retaining edge 20 at the right-angle position is provided with a countersunk groove 23. It can be understood that the outline size of the countersunk groove 23 can be determined according to the outline size of the magnetic positioning seat 30. One end of the magnetic positioning seat 30 engages with the countersunk groove 23, and the other end has an inner arc surface or ring adapted to the structure of the TCB assembly 40, extending to the inner side of the retaining edge 20. Understandably, when it is an inner arc surface, the outer connection end of the TCB assembly 40 (the opposite end being the paste application end) contacts this inner arc surface. That is, the TCB assembly 40 is limited and fixed by the inner arc surface of the magnetic positioning seat 30. At this time, the inner arc surface can provide the TCB assembly 40 with axial magnetic attraction and radial magnetic attraction towards the retaining edge 20. Figure 6-7 As shown; when it is a ring, the outer connection end of the TCB assembly 40 can be nested inside the ring for limiting and fixing. The ring provides magnetic attraction in both axial and radial directions for the TCB assembly 40. In this embodiment, the former is preferred, that is, the magnetic positioning seat 30 is provided with an inner arc surface adapted to the TCB assembly 40, such as... Figure 3As shown, this design structure reduces the volume of the magnetic positioning seat 30 on the one hand, and effectively fixes the TCB component 40 on the other hand, preventing it from shifting radially and axially, thus laying the foundation for subsequent paste application and handling.

[0031] Figures 4b-4c show two design structures of the countersunk groove 23 on the retaining member 20 provided in this embodiment, and Figures 5a-5b show two design structures of the magnetic positioning seat 30 provided in this embodiment. As can be seen from the figures, the structure of the countersunk groove 23 is adapted to the structure of one end of the magnetic positioning seat 30. Specifically, the end of the magnetic positioning seat 30 that is embedded in the countersunk groove 23 has a right-angle structure or an outwardly convex arc surface structure. In addition, the length of the end of the magnetic positioning seat 30 extending to the inner side of the retaining member 20 should be sufficient to ensure that the TCB component 40 is limited to the specified position.

[0032] As a preferred embodiment, the base plate 10 is a rectangular plate, the size of which can be selected according to actual needs. The base plate 10 is provided with a limiting groove 11 and a threaded hole 12, such as... Figure 2 As shown, in this preferred embodiment, the limiting groove 11 includes a side limiting groove 11 and a magnetic seat limiting groove 11. Simultaneously, positioning holes 24 are provided on the two sides. The first side 21, the second side 22, and the magnetic positioning seat 30 are respectively embedded in the corresponding limiting grooves 11 and fixed by bolts engaging with the threaded holes 12 and the positioning holes 24. Figure 1 As shown.

[0033] As a preferred embodiment, after fixing the TCB component 40 to the magnetic positioning base 30, there is a 0.5-1mm gap between the inner arc surface and the upper plane of the magnetic positioning base 30 and the TCB component 40. Specifically, after installation, the stepped protrusion in the middle area of ​​the TCB component 40 first contacts the edge of the edge retainer 20, so that the outer mating end of the TCB component 40 is 0.5-1mm away from the edge retainer. At the same time, the height of the outer mating end of the TCB component 40 is 0.5-1mm higher than the magnetic positioning base 30. That is, after installation, the TCB component 40 and the magnetic positioning base 30 are not in complete contact. This method is beneficial for the quick placement and removal of the TCB component 40, and can reduce the frictional damage to the TCB component 40 caused by direct contact.

[0034] As a preferred embodiment, the base plate 10 and the edge guard 20 are made of metal substrates such as aluminum profiles and stainless steel. At the same time, a wear-resistant layer can be coated on the surface of the metal substrate using processes such as chrome plating. The above are the preferred materials for the base plate 10 and the edge guard in this embodiment. If necessary, hard wear-resistant engineering plastics such as nylon can also be used.

[0035] In use, each TCB component 40 is placed on the corresponding edge block 20, and the TCB component 40 is positioned and fixed by the magnetic positioning seat 30 set on the edge block 20. No additional clamping device is required, and there is no need to adjust the height structure of the edge block 20.

[0036] In summary, this embodiment places the magnetic positioning seat 30 at one end of the inner side of the retaining member 20, which can simultaneously provide adsorption forces in both axial and radial directions to the TCB assembly 40. On the one hand, this significantly improves the stability of the TCB assembly 40, and on the other hand, it facilitates the quick placement and removal of the TCB assembly 40 on the fixture, effectively improving work efficiency. It can be seen that the sodium-nickel battery TCB assembly paste fixing fixture of this embodiment has a compact structure and is easy to use. It solves the shortcomings of the existing spring clamp holding method, which makes the TCB assembly 40 easy to loosen and bounce, and also solves the shortcomings of the existing method of raising the retaining member 20, which easily causes paste defects.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
