Description

Technical Field

[0001] The present application relates to the technical field of lithium-ion battery positive electrode material manufacturing equipment, and in particular to a demagnetization tool for a kiln circulation line. Background Art

[0002] The kiln circulation line is a professional equipment for the sintering process of the battery positive electrode material production line. It can realize the functions of automatic conveying of saggers, automatic separation of saggers, automatic pouring of materials, automatic cleaning, automatic quantitative loading of saggers, automatic shaking, and automatic stacking of saggers. During the above mechanical movement, metal foreign matter will be generated inside the kiln circulation line and deposited on the bottom wall of the kiln circulation line. During the operation of the kiln circulation line, these metal foreign matter may be mixed into the positive electrode material, resulting in a sharp decline in product performance and even safety hazards. Therefore, in order to ensure the performance of battery products and reduce safety hazards, the kiln circulation line needs to undergo a demagnetization process.

[0003] The traditional manual demagnetization method requires opening the upper cover of the kiln circulation line and manually holding a permanent magnet to perform the demagnetization work. The demagnetization efficiency is low, there are blind spots for demagnetization, and there is a risk of foreign matter being introduced during the demagnetization process. Utility Model Content

[0004] The purpose of this application is to provide a demagnetization tool for a kiln circulation line, which has high demagnetization efficiency, improves the demagnetization effect, and avoids the risk of introducing other foreign matter.

[0005] In order to solve the above-mentioned technical problems, the present application provides a demagnetization tool for a kiln circulation line. The kiln circulation line has a bottom wall and a roller conveying mechanism. The roller conveying mechanism is arranged above the bottom wall. The demagnetization tool includes a non-metallic frame and a magnetic suction component. The non-metallic frame and the magnetic suction component are connected to each other. The demagnetization tool has preset external dimensions. The demagnetization tool can be placed on the roller conveying mechanism for transportation, and the metal foreign matter deposited on the bottom wall can be adsorbed by the magnetic suction component.

[0006] The demagnetization tool of this embodiment includes a non-metallic frame and a magnetic attraction component. The non-metallic frame is connected to the magnetic attraction component, so that the demagnetization tool has preset external dimensions. The preset external dimensions here refer to the external dimensions of the demagnetization tool being consistent with the external dimensions of the sagger. In this way, when it is necessary to demagnetize the kiln circulation line, the demagnetization tool can be placed on a roller conveying mechanism for transportation, and the magnetic attraction component in the demagnetization tool can face the bottom wall of the kiln circulation line. During the operation of the kiln circulation line, the demagnetization tool runs to each workstation under the conveying action of the roller conveying mechanism, and absorbs metal foreign matter deposited on the bottom wall. The demagnetization efficiency is high, and there is no dead corner for demagnetization, thereby achieving an efficient demagnetization effect.

[0007] At the same time, since the kiln circulation line is in a closed state when demagnetizing, there is no need to open the upper cover of the kiln circulation line like the traditional manual demagnetization method, thereby avoiding the introduction of external foreign matter into the kiln circulation line.

[0008] Optionally, the non-metallic frame has an embedding groove with one end open, the magnetic attraction component is at least partially embedded in the embedding groove, and the magnetic attraction component is exposed on the side wall of the embedding groove to absorb the metal foreign matter.

[0009] Optionally, the magnetic attraction component is embedded in the embedding groove, and the side wall of the magnetic attraction component exposed from the embedding groove is flush with the open end wall of the non-metallic frame.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please refer to Figure 1-Figure 2 , Figure 1 A schematic structural diagram of a specific embodiment of the demagnetization tool provided in this application; Figure 2 for Figure 1 Schematic diagram of the structure of the demagnetization tool during demagnetization.

[0035] In a specific embodiment of the demagnetization tool for a kiln circulation line provided in the present application, the kiln circulation line 01 has a bottom wall 011 and a roller conveying mechanism 012, the roller conveying mechanism 012 is arranged above the bottom wall 011, and the roller conveying mechanism 012 is used to realize the conveyance of the sagger during operation;

[0036] The demagnetization tool 1 includes a non-metallic frame 11 and a magnetic component 12 which are connected to each other. The demagnetization tool 1 has a preset outer dimension. The demagnetization tool 1 can be placed on a roller conveying mechanism 012 for transportation, and the magnetic component 12 can absorb metal foreign matter deposited on the bottom wall 011.

[0037] The demagnetization tool 1 of this embodiment includes a non-metallic frame 11 and a magnetic attraction member 12. The magnetic attraction member 12 is used to absorb metal foreign matter deposited on the bottom wall 011 during demagnetization. The non-metallic frame 11 is used to make the demagnetization tool 1 have preset external dimensions after being connected to the magnetic attraction member 12. The preset external dimensions here refer to the external dimensions of the demagnetization tool 1 being consistent with the external dimensions of the sagger. In this way, when it is necessary to demagnetize the kiln circulation line 01, the demagnetization tool 1 can be placed on the roller conveying mechanism 012 for transportation, and the magnetic attraction member 12 in the demagnetization tool 1 is made to face the bottom wall 011 of the kiln circulation line 01. During the operation of the kiln circulation line 01, the demagnetization tool 1 runs to each workstation under the conveying action of the roller conveying mechanism 012, and absorbs metal foreign matter deposited on the bottom wall 011. The demagnetization efficiency is high, and there is no dead angle for demagnetization, thereby achieving an efficient demagnetization effect.

[0038] At the same time, since the kiln circulation line 01 is in a closed state when the kiln circulation line 01 is demagnetized, there is no need to open the upper cover of the kiln circulation line 01 like the traditional manual demagnetization method, thereby avoiding the introduction of external foreign matter into the kiln circulation line 01; except for the magnetic suction part 12, all the demagnetization tools 1 are designed with non-metallic materials. No additional metal foreign matter will be generated during use, and the environmental quality of the kiln circulation line 01 will not be affected.

[0039] Please continue to refer to Figure 1 , Figure 3-Figure 4 , Figure 3 for Figure 1 A schematic diagram of the structure of the demagnetization tool at a second angle; Figure 4 for Figure 1 Schematic diagram of the structure of the demagnetization tool from the third angle.

[0040] In this embodiment, the non-metallic frame 11 has an embedding groove with an open end, and the magnetic attraction component 12 includes a plate portion 121 and a protrusion 122. The protrusion 122 is connected to one side of the plate portion 121, and the magnetic attraction component 12 is embedded in the embedding groove. The side wall of the plate portion 121 facing away from the protrusion 122 is exposed in the embedding groove, and the side wall of the plate portion 121 facing away from the protrusion 122 is flush with the open end wall of the non-metallic frame 11.

[0041] As configured above, the non-metallic frame 11 is wrapped around the magnetic attraction part 12. When the kiln circulation line 01 is demagnetized, the side wall of the plate portion 121 facing away from the protrusion 122 and the open end wall of the non-metallic frame 11 are supported on the roller conveying mechanism 012. The side wall of the plate portion 121 facing away from the protrusion 122 is used to adsorb metallic foreign matter. The other side walls of the demagnetization tool 1 are made of non-metallic materials to avoid magnetic attraction between the demagnetization tool 1 and other metal structures in the kiln circulation line 01, thereby ensuring the normal circulation of the demagnetization tool 1.

[0042] Depend on Figure 1 It can be seen that in this embodiment, the side wall of the plate portion 121 facing away from the protrusion 122 is flush with the opening end wall of the non-metallic frame 11. In practice, it is also feasible that the side wall of the plate portion 121 facing away from the protrusion 122 is recessed into the opening end wall of the non-metallic frame 11, as long as the magnetic attraction member 12 has sufficient magnetic attraction to absorb the metal foreign matter deposited on the bottom wall 011.

[0043] Depend on Figure 1 It can be seen that in this embodiment, the cross-sectional area of ​​the plate portion 121 is greater than the cross-sectional area of ​​the protruding portion 122 .

[0044] In practice, the magnetic material is mainly added inside the protrusion 122, so that the plate portion 121 has sufficient magnetic attraction, and the cross-sectional area of ​​the plate portion 121 is larger than the cross-sectional area of ​​the protrusion 122, which can increase the adsorption area of ​​the magnetic part 12 and improve the adsorption capacity of the magnetic part 12, so that the metal foreign matter deposited on the bottom wall 011 can be attracted by the magnetic part 12 as much as possible, thereby improving the demagnetization effect of the demagnetization tool 1.

[0045] In order to accommodate the above-mentioned plate portion 121 and protrusion 122, the embedding groove specifically includes a first groove portion and a second groove portion. The first groove portion is closer to the opening end of the embedding groove than the second groove portion. The structural dimensions of the first groove portion match the plate portion 121, and the structural dimensions of the second groove portion match the protrusion 122. The protrusion 122 is located inside the second groove portion, and the plate portion 121 is located inside the first groove portion, thereby realizing the embedding design of the magnetic suction component 12.

[0046] Depend on Figure 4 It can be seen that in this embodiment, the cross-sections of the plate portion 121 and the protrusion 122 are both square. When the magnetic member 12 is embedded in the embedding groove, the magnetic member 12 and the embedding groove can be limited along the circumferential direction to achieve a reliable connection between the magnetic member 12 and the non-metallic frame 11. In practice, the cross-sections of the plate portion 121 and the protrusion 122 are not limited to the above implementation methods, such as the plate portion 121 and the protrusion 122 can also be rectangular.

[0047] As can be seen from the foregoing, in the first embodiment, the magnetic attraction member 12 is completely embedded in the embedding groove. Figure 5, Figure 5 This is a cross-sectional view along the thickness direction of the second specific embodiment of the demagnetization tool provided in the present application.

[0048] In the second embodiment, the protrusion 122 is embedded in the embedding groove, the plate portion 121 is located outside the embedding groove, the side wall of the plate portion 121 connected to the protrusion 122 is in contact with the opening end wall of the non-metallic frame 11, and the side wall of the plate portion 121 facing away from the protrusion 122 and the peripheral wall of the plate portion 121 are exposed in the embedding groove. It can be seen that in this embodiment, the magnetic attraction member 12 is only partially embedded in the embedding groove.

[0049] In this way, when the kiln circulation line 01 is demagnetized, the side wall of the plate portion 121 facing away from the protrusion 122 is supported on the roller conveying mechanism 012, and the side wall of the plate portion 121 facing away from the protrusion 122 and the surrounding wall of the plate portion 121 can be used to adsorb metal foreign matter, thereby increasing the adsorption area of ​​the magnetic part 12 and improving the adsorption capacity of the magnetic part 12.

[0050] Please refer to Figure 6 , Figure 6 This is a cross-sectional view along the thickness direction of the third specific embodiment of the demagnetization tool provided in the present application.

[0051] In the third embodiment, the cross-sectional areas of the plate portion 121 and the protrusion 122 are equal, that is, the cross-sectional area of ​​the magnetic member 12 is always equal. In practice, the cross-sectional area of ​​the magnetic member 12 is not limited as long as the magnetic member 12 can have sufficient adsorption capacity.

[0052] Furthermore, in some embodiments of the application, the non-metallic frame 11 and the magnetic attraction component 12 can be connected together through an insert injection molding process.

[0053] Specifically, during the molding process, the magnetic component 12 can be first loaded into the mold, and then the molten material can be injected into the mold. After the molten material and the magnetic component 12 are joined and solidified, a blank of the demagnetization tool 1 is formed. After fine processing of the blank, a demagnetization tool 1 with preset external dimensions is obtained.

[0054] The above molding method can improve the connection reliability between the non-metal frame 11 and the magnetic member 12, thereby improving the process quality of the demagnetization tool 1. Of course, in practice, the non-metal frame 11 and the magnetic member 12 are not limited to the above connection method, such as the non-metal frame 11 and the magnetic member 12 can also be fixed by bonding, or interference fit, etc.

[0055] Please refer to Figure 7 , Figure 7 This is a cross-sectional view along the thickness direction of the fourth specific embodiment of the demagnetization tool provided in the present application.

[0056] In the above three embodiments, the magnetic member 12 is at least partially embedded in the non-metallic frame 11, and the magnetic member 12 is exposed on the side wall of the embedding groove to absorb metal foreign matter. In practice, it is also feasible to connect the magnetic member 12 to one side of the non-metallic frame 11, such as Figure 7 As shown, in the fourth embodiment, the cross-sectional area of ​​the magnetic component 12 is equal to the cross-sectional area of ​​the non-metallic frame 11, and the side wall of the plate portion 121 facing away from the protrusion 122 and the peripheral wall of the plate portion 121 can be used to adsorb metal foreign matter, thereby increasing the adsorption area of ​​the magnetic component 12 and improving the adsorption capacity of the magnetic component 12.

[0057] In this embodiment, the magnetic element 12 and the non-metal frame 11 can be fixed by bonding.

[0058] Furthermore, in some embodiments of the application, the magnetic attraction member 12 is a permanent magnet.

[0059] It is understandable that, in practice, the magnetic attraction member 12 can also achieve the adsorption of metal foreign matter by using an electromagnet, but the electromagnet structure may make the demagnetization tool 1 more complicated and increase the cost of the demagnetization tool 1. Therefore, it is a more preferred technical solution that the magnetic attraction member 12 uses a permanent magnet.

[0060] In addition, the material of the non-metal frame 11 includes but is not limited to synthetic resin and the like.

[0061] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
