[0024] Before providing a more detailed description of the invention, the structure of the fusible electrode tab will be explained first:

[0025] like Figure 1 As shown, a fusible electrode consists of an electrode tab (metal tab), a fusible opening (usually a Z-shaped fusible opening) on ​​the electrode tab, and electrode adhesive covering the electrode tab. The electrode adhesive seals the fusible opening. The electrode tab is a conductive substrate, typically made of metal.

[0026] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 2 Detailed explanation. Figure 2A schematic block diagram of a fully automated processing device for fusible electrode tabs according to an embodiment of the present invention is shown. The fully automated processing device for fusible electrode tabs in this embodiment includes:

[0027] The material feeding section 1, the first electrode tab adhesive coating section 2, the fuse hole punching section 3, the second electrode tab adhesive coating section 4, and the cutting section 5;

[0028] The feeding section 1 provides the tab strip to be processed; the first tab adhesive coating section 2 coats the tab strip with a first tab adhesive layer, thereby forming a punched portion on the tab strip; the fusing punching section 3 performs fusing punching on the punched portion to form a secondary adhesive coating portion on the tab strip; the second tab adhesive coating section 4 coats the secondary adhesive coating portion with a second tab adhesive layer to obtain a fusing tab strip to be cut; and the cutting section 5 cuts the fusing tab strip to be cut to obtain a fusing tab.

[0029] Specifically, the first tab adhesive-coated section, the fusing point punching section, and the second tab adhesive-coated section are arranged sequentially according to the processing order. Each section processes the tab strip accordingly to form a fusing tab strip. Finally, the cutting section cuts the fusing tab strip into sheets to obtain multiple fusing tabs.

[0030] In one embodiment, such as Figure 3 As shown, the feeding section includes a feeding station 11 and a leveling station 12; wherein, the feeding station 11 is used to place the tab coil; the leveling station 12 is used to level the tab coil to obtain the tab strip to be processed. The tab strip to be processed is as follows: Figure 4 As shown in state A. It should be understood that, Figure 4 Each state only shows a portion of the tab material; the state of the remaining portions is the same as the shown portion.

[0031] It should be understood that the tab coil is made of metal and is the raw material for the tab sheet. The leveling process involves flattening the tab coil.

[0032] In one embodiment, the first tab adhesive coating section includes: a first preheating station 21 for preheating the tab strip; a first adhesive coating station 22 for coating the tab strip with a first tab adhesive layer; and a first shaping station 23 for pressing the first tab adhesive layer to fix it onto the tab strip. The state of the tab strip after passing through the first tab adhesive coating section is as follows: Figure 4 As shown in state B. The part to be punched is as follows. Figure 4 As shown in state B, it is composed of a first tab adhesive layer and a tab strip material covered by the first tab adhesive layer.

[0033] It should be understood that the preheating station is generally a heating table with built-in heating elements. The shaping station uses a hot press or hot pressing equipment, which is a specific area used to heat and pressurize materials or products. It is usually equipped with heating devices, pressure application devices, and platforms or molds for placing the items to be processed.

[0034] In one embodiment, such as Figure 3 As shown, section 3, the punching section at the fuse break, is a punching station. This station is used to simultaneously punch the first tab adhesive layer and the tab strip portion covered by the first tab adhesive layer, obtaining the portion to be coated with adhesive a second time. The portion to be coated with adhesive a second time is as follows: Figure 4 As shown in state C, it consists of a portion to be punched and a welded opening formed on that portion. It should be noted that if holes are punched directly onto the tab strip, the strength of the metal strip will decrease after two openings. The strip cannot be subjected to force during forward movement, otherwise it will break. The method of coating the first tab with an adhesive layer and then punching holes in the coated strip solves the problem of easy breakage when directly punching holes on the tab strip.

[0035] In one embodiment, such as Figure 4 As shown in state C, the fuse is a Z-type fuse.

[0036] In one embodiment, such as Figure 3 As shown, the second tab adhesive coating section 4 includes: a second preheating station 41 for preheating the part to be coated a second time; and a second coating station 42 for coating the part to be coated a second time with the second tab adhesive layer, the coated state being as shown. Figure 4 As shown in state D; the second shaping station 43 is used to simultaneously press the first tab adhesive layer and the second tab adhesive layer; the hot melting station 44 is used to heat the first tab adhesive layer and the second tab adhesive layer and fuse them together.

[0037] It should be understood that the second tab adhesive layer is used to complete... Figure 1 The function of the tab adhesive is shown. The preheating station is generally a heating table with built-in heating elements. The shaping station uses a hot press or hot pressing equipment, which is a specific area used to heat and pressurize materials or products. It is typically equipped with heating devices, pressure application devices, and a platform or mold for placing the items to be processed.

[0038] In one embodiment, such as Figure 3 As shown, the cutting section 5 includes: a rubber shoulder cutting station 51, which is used to cut the rubber shoulder of each rubber in the fusible rubber material to be cut according to the preset rubber shoulder size.

[0039] It should be understood that, like, rubber shoulders Figure 1The image shows the portion of the tab adhesive extending outwards from the edge of the tab. The tab adhesive shoulder is trimmed to meet pre-defined dimensions. These dimensions include the shoulder height and width. The shoulder dimensions can be set according to actual needs and are not limited here.

[0040] In one embodiment, such as Figure 3 As shown, the cutting section 5 includes a material pulling station 52 and a cutting station 53; wherein, the material pulling station 52 is used to convey the fusible electrode material after the rubber shoulder cutting process to the cutting station 53, so that the cutting station can cut it according to the preset size of the fusible electrode, thereby obtaining the fusible electrode. It should be understood that the size of the fusible electrode can be set according to requirements, and the present invention does not limit it.

[0041] It should be noted that the existing tab production equipment processes as follows: raw materials are fed in roll form to the feeding station, then guided to the pressing station and the adhesive coating station. Mechanical fingers then pass the adhesive and unadhesive layers of the tab through the material. The adhesive coating station then presses the material together to bond the adhesive to the metal. The material then passes through the venting station, the fusing station, and the shaping station to ensure the product meets performance requirements. Finally, it is cut to the set specifications at the cutting station. Thus, existing tab production equipment sequentially coats and fuses the tab roll. After fusing, it is sliced ​​to obtain the final tab. However, existing tab production equipment cannot meet the production requirements of fusible tabs. The tab production equipment of this invention can not only automatically and continuously produce multiple fusible tabs, improving production efficiency, but also solves the problem of fusible tabs easily breaking during continuous production.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0043] In summary, this application provides a fully automated processing equipment for fusible tabs. The equipment includes: a feeding section, a first tab adhesive coating section, a fusing point punching section, a second tab adhesive coating section, and a cutting section. The feeding section provides the tab strip to be processed. The first tab adhesive coating section coats the tab strip with a first tab adhesive layer, forming a punched portion on the tab strip. The fusing point punching section performs a fusing punching operation on the punched portion to form a portion to be coated with adhesive for secondary bonding. The second tab adhesive coating section coats the portion to be coated with adhesive with a second tab adhesive layer to obtain a fusible tab strip to be cut. The cutting section cuts the fusible tab strip to obtain fusible tabs. This fully automated processing equipment for fusible tabs can automatically process fusible tabs, improving production efficiency. Therefore, this application effectively overcomes the various shortcomings of the prior art and has high industrial applicability.

[0044] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
