For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] The utility model provides a tool 100 for analyzing the quality characteristics of a gold-sprayed electrode.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] In the embodiment of the present utility model, Figure 1 , Figure 2 and Figure 3 As shown, the tooling 100 for analyzing the quality characteristics of gold-sprayed electrodes includes a turntable mechanism 10, a fixing seat 20, an electrode module 30 and a spray gun 40, wherein the turntable mechanism 10 includes a turntable 11 and a drive motor 12, and the drive motor 12 drives the turntable 11 to rotate; there are three fixing seats 20 that are evenly distributed on the top of the turntable 11, and the fixing seat 20 is provided with a plurality of fixing columns 21 at intervals along the radial direction; the electrode module 30 is designed in a core-like shape, and the electrode module 30 has a plurality of fixing columns 21 that are respectively arranged on the plurality of fixing columns, and a material trough 34 is provided on the top of the electrode module 30; the spray gun 40 is located at the top of the turntable mechanism 10, and sprays back and forth along the radial direction of the turntable 11.

[0036] It can be understood that the three fixing seats 20 are evenly distributed around the circumference, that is, the angle formed between adjacent fixing seats 20 is 120°, and each fixing seat 20 is provided with a plurality of electrode modules 30, so that the electrode modules 30 are evenly distributed, and the driving motor 12 drives the turntable 11 to rotate, so that the fixing seats 20 are aligned with the spray gun 40 above in turn, and the spray gun 40 is driven by a power device to move, specifically reciprocating along the radial direction of the turntable 11 to realize gold spraying of the plurality of electrode modules 30 on the fixing seat 20, and the electrode metal material is melted by arc heating at the spray gun 40, and the metal particles are sprayed into the material trough 34 of the electrode module 30 by compressed air, thereby obtaining an electrode sample block. By setting a material trough 34, the shape of the electrode sample block formed after gold spraying is restricted, so that multiple electrode sample blocks have a uniform shape and thickness. At the same time, the electrode modules 30 are respectively set on three fixed seats 20 evenly distributed around the circumference, which can also increase the sampling area. By increasing the sample volume of the electrode module 30 and optimizing the layout of the electrode sampling, it is helpful to statistically analyze whether the thickness characteristics of the electrode within the spraying range meet the requirements. The electrode module 30 of the utility model is directly placed on the fixed column 21, which is convenient for disassembly and assembly. The electrode module 30 structure designed with a core-like shape replaces the existing electrode module 30 structure, and the top of the electrode module 30 is provided with a material trough 34. This structure eliminates the burr phenomenon on the edge of the electrode after spraying caused by the lack of external structure restrictions of the previous electrode module 30, resulting in the non-uniform size of the sample block, and the distortion of the electrode thickness measured by the micrometer due to the influence of roughness. The electrode module 30 designed with a core-like shape keeps the size of the electrode sample block after sampling consistent, which meets the consistency of the thickness analysis of each electrode sample block by weighing using a high-precision electronic scale.

[0037] In addition, the electrode module 30 is specially designed according to the shape of the capacitor core, and each electrode module 30 is an independent small unit. Especially in the normal production process, it is usually necessary to sample the thickness characteristics of the gold spraying to make an SPC control chart, and the independent small unit is conducive to the reasonable placement of the sample block and data collection.

[0038] The technical solution of the utility model includes a turntable mechanism 10, a fixing seat 20, an electrode module 30 and a spray gun 40. There are three fixing seats 20 and they are evenly distributed on the top of the turntable 11. The fixing seat 20 is provided with a plurality of fixing posts 21 at intervals along the radial direction. The electrode module 30 is designed in the shape of a core, and the plurality of electrode modules 30 are respectively arranged on the plurality of fixing posts 21. Since the technical means of evenly distributing the fixing seats 20 on the circumference and arranging a plurality of electrode modules 30 on the fixing seat 20 is adopted, the technical problems of limited analysis position, too little sample amount and non-uniform size of electrode sample blocks in the prior art are effectively solved, thereby achieving the technical effects of increasing the sample amount, increasing the sampling coverage area and improving the uniformity of the sample blocks.

[0039] In the embodiment of the present utility model, Figures 4 to 7 As shown, the electrode module 30 includes a lower connecting member 31, an upper connecting member 32 and a gasket 33, wherein the lower connecting member 31 is provided with a positioning groove 311 for cooperating with the fixing column 21; the upper connecting member 32 is arranged at the top of the lower connecting member; the gasket 33 is arranged at the top of the upper connecting member 32, and the gasket 33 is provided with a through hole 331, and a material trough 34 is formed at the position where the through hole 331 is located.

[0040] In the present invention, the electrode module 30 is a split structure, and two adjacent parts can be detachably connected, which is convenient for maintenance and replacement. The fixing column 21 of the present invention is a cylindrical structure, and the positioning groove 311 is adapted to its shape.

[0041] In the embodiment of the present utility model, Figures 4 to 7 As shown, the lower connecting member 31 and the upper connecting member 32 are connected by a threaded fastener, and the upper connecting member 32 and the gasket 33 are connected by a threaded fastener. The threaded fastener has the characteristic of being easy to disassemble and assemble.

[0042] In the embodiment of the present utility model, Figures 4 to 7 As shown, a positioning column 321 is provided on the top of the upper connecting member 32, and a positioning hole 332 is provided on the gasket 33 to cooperate with the positioning column 321. The positioning column 321 and the positioning hole 332 are provided to facilitate the installation and positioning of the gasket 33, thereby forming an electrode sample block with a fixed position and uniform shape.

[0043] In the embodiment of the present utility model, Figure 4 and Figure 7 As shown, the through hole 331 is circular in shape, thereby forming a disc-shaped electrode sample block.

[0044] Specifically, a through hole 331 and two round holes are provided on the gasket 33. The two round holes are located on the opposite side of the through hole 331. One of the round holes is used to install a threaded fastener, and the other round hole is a positioning hole 332. The positioning hole 332 cooperates with the positioning column 321 of the upper connecting member 32 to achieve positioning. At the same time, the threaded fastener passes through the other round hole and is threadedly connected with the upper connecting member 32 to achieve a fastening effect. A positioning groove 311 that cooperates with the fixing column 21 is provided at the bottom of the lower connecting member 31. Another threaded fastener passes through the positioning groove 311 and is threadedly connected with the upper connecting member 32 to achieve a fastening effect.

[0045] In the embodiment of the utility model, the lower connecting member 31 has different height specifications. The lower connecting member 31 can also be designed according to different core heights to ensure that it is consistent with the height of the capacitor core. The core-shaped design can quickly place the electrode module 30 small unit in the core disk to replace the capacitor core to sample the gold spraying thickness. This structure eliminates the inconvenient and unreasonable shortcomings of the original electrode module 30 in normal production operations.

[0046] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
