The demagnetization method is simple and has high demagnetization efficiency.

Description

Technical Field

[0001] This application relates to the field of battery manufacturing tools, and more particularly to a demagnetizing device. Background Technology

[0002] The production process of lithium battery cathode materials places extremely high demands on the environmental requirements of the manufacturing workshop, which must be free of any metallic foreign objects. To prevent the presence of metallic foreign objects in the workshop, they must be adsorbed and removed, i.e., demagnetized.

[0003] Existing demagnetizing devices involve a cumbersome and time-consuming process of disassembling the outer casing and then demagnetizing. Iron impurities adsorbed on the magnetic rods need to be manually removed, which is also time-consuming and inefficient. Furthermore, friction between the machine body and materials or external equipment generates metal particles, which can directly contaminate the workshop environment, posing a high risk of metal contamination. In addition, strong magnetic adsorption may cause operators to injure their fingers, or adsorption onto walls may damage the walls or the demagnetizing device. Moreover, the carbon steel demagnetizing device requires rust prevention treatment, resulting in high maintenance costs. Utility Model Content

[0004] In view of this, this application proposes a demagnetizing device to improve demagnetization efficiency, reduce the risk of metal introduction, operational difficulty and maintenance costs, and ensure safe operation.

[0005] A demagnetizing device includes a housing, a magnetic component, a lifting mechanism, and a moving mechanism. The housing has an interior cavity in which the magnetic component is housed. The lifting mechanism includes a handle and a connector; the handle is located outside the cavity, and a portion of the connector is located inside the cavity. One end of the connector is connected to the handle, and the other end is connected to the magnetic component. The connector is configured to move up and down within the cavity, thereby causing the magnetic component to move up and down within the cavity. The moving mechanism is connected to the housing and is used to move the housing.

[0006] In one embodiment, the outer casing has a through hole on its surface facing the handle. The connector includes a first part and a second part connected to each other, the first part being fixedly connected to the handle, and the second part being connected to the magnetic element. The second part is configured to move up and down within the cavity and the through hole.

[0007] In one embodiment, the second part has a recess, and the magnetic element is engaged in the recess.

[0008] In one embodiment, the connector further includes a protrusion. The protrusion is located at the junction of the first portion and the second portion and outside the cavity, protruding beyond the surface of the first portion.

[0009] In one embodiment, the inner surface of the housing is provided with a guide groove, and the two ends of the magnetic element in the extension direction are configured to move up and down in the cavity along the guide groove.

[0010] In one embodiment, the demagnetizing device further includes an operating mechanism. The operating mechanism includes a connecting portion and an operating rod. The connecting portion is disposed within the cavity, and the magnetic element passes through the connecting portion. The operating rod is connected to the connecting portion and extends out of the cavity.

[0011] In one embodiment, the connecting part is provided with an external thread, and the operating rod is provided with an internal thread adapted to the external thread. The connecting part and the operating rod are connected by the external thread and the internal thread.

[0012] In one embodiment, the moving mechanism includes a wheel. The wheel is connected to the housing and is equipped with a locking mechanism.

[0013] In one embodiment, the moving mechanism further includes a protective cover. The protective cover is disposed on the housing and corresponding to the wheel, and the protective cover covers the wheel.

[0014] In one embodiment, both the outer shell and the lifting mechanism are made of polypropylene.

[0015] The demagnetizing device of this application, by setting up a magnetic component, handle, connector and other structures, allows the operator to simply lift the handle and the connector to move the magnetic component upward in the cavity of the outer shell. The metal impurities adsorbed at the bottom of the outer shell will fall off automatically due to the weakening of the magnetic attraction, or they can be removed by the operator with just a light touch or scrape. The demagnetizing method is simple and the demagnetizing efficiency is high. Attached Figure Description

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please see Figure 1 and Figure 2 This application provides a demagnetizing device 100, including a housing 10, a magnetic element 20, a lifting mechanism 30, and a moving mechanism 40. A cavity 11 is formed inside the housing 10, and the magnetic element 20 is housed within the cavity 11. The lifting mechanism 30 includes a handle 31 and a connector 32. The handle 31 is located outside the cavity 11, and a portion of the connector 32 is located inside the cavity 11. One end of the connector 32 is connected to the handle 31, and the other end is connected to the magnetic element 20. The connector 32 can move up and down within the cavity 11, thereby causing the magnetic element 20 to move up and down within the cavity 11. The moving mechanism 40 is connected to the housing 10 and is used to move the housing 10, thereby moving the magnetic element 20.

[0028] like Figure 1 As shown, when the demagnetizing device 100 is in working condition (demagnetizing), the operator can push the outer casing 10 through the moving mechanism 40, thereby moving the magnetic component 20. At this time, the handle 31 is not lifted, and the magnetic component 20 is close to the bottom of the outer casing 10. The magnetic force of the magnetic component 20 can penetrate the outer casing 10, thereby adsorbing the metal impurities on the bottom of the outer casing 10, completing the demagnetizing operation.

[0029] like Figure 2 As shown, when demagnetization is complete and demagnetization is required, the operator can lift the handle 31. The connecting piece 32 will rise along with the handle 31, thereby lifting the magnetic component 20 connected to the connecting piece 32. When the magnetic component 20 is raised to a certain distance from the bottom of the outer casing 10, the distance between the magnetic component 20 and the metal impurities it has attracted increases, and the magnetic force of the magnetic component 20 is greatly weakened. The metal impurities will fall off by themselves due to their own gravity, or the operator only needs to gently touch or scrape them to make them all fall off the outer casing 10, thus completing the demagnetization operation. That is, the demagnetization device 100 of this application can easily achieve the demagnetization operation simply by the operator lifting the handle 31, and the demagnetization method is simple and efficient.

[0030] like Figure 1 and Figure 2As shown, in some embodiments, the outer shell 10 has a cuboid structure, but this is not a limitation. The outer shell 10 may include a top wall 12, a bottom wall 13, a first side wall 14, a second side wall 15, and a third side wall 16. The top wall 12 and the bottom wall 13 are arranged opposite each other, and the first side wall 14 and the second side wall 15 are arranged opposite each other. The first side wall 14 is connected to one end of the top wall 12 and the bottom wall 13, and the second side wall 15 is connected to the other end of the top wall 12 and the bottom wall 13. The third side wall 16 is connected to the top wall 12, the bottom wall 13, the first side wall 14, and the second side wall 15. The top wall 12, the bottom wall 13, the first side wall 14, the second side wall 15, and the third side wall 16 together form a cavity 11. The size of the outer shell 10 can be adjusted according to actual needs, and this application does not impose any limitations.

[0031] Furthermore, the handle 31 may be located on the top wall 12 (the handle 31 does not contact the top wall 12), and the handle 31 may be, but is not limited to, cylindrical. The connector 32 may pass through the top wall 12 to connect with the magnetic element 20 inside the cavity 11. The magnetic element 20 may be a permanent magnet rod, and its extension direction (axial direction) may be the arrangement direction of the first sidewall 14 and the second sidewall 15. That is, the first sidewall 14 and the second sidewall 15 are located at the two ends of the extension direction of the magnetic element 20, respectively. The extension direction (axial direction) of the cylindrical handle 31 may be parallel to the extension direction of the permanent magnet rod. The diameter and size of the permanent magnet rod may be adjusted according to actual conditions, and the diameter and length of the handle 31 may also be adjusted according to actual conditions; this application does not impose any limitations.

[0032] In some embodiments, the housing 10, handle 31, and connector 32 are all made of polypropylene (PP). The PP (non-metallic) housing 10 eliminates the risk of metal contamination caused by metal wear. Furthermore, PP is lightweight and will not adhere to other equipment or walls, making operation safer, easier, and less strenuous. In addition, PP has good corrosion resistance to most acids, alkalis, and solvents, and its smooth surface allows for direct washing and easy cleaning, reducing the maintenance cost of the demagnetizing device 100.

[0033] In some embodiments, such as Figure 2As shown, the outer casing 10 has a through hole 120 on its surface facing the handle 31. That is, the top wall 12 has a through hole 120 that penetrates the top wall 12 along its thickness direction. The number of through holes 120 can be one or more, corresponding to the number of connectors 32. The number of connectors 32 can also be one or more. In this embodiment, there are two connectors 32 and two through holes 120. The two connectors 32 can be connected to both ends of the handle 31 respectively. The connectors 32 can be, but are not limited to, sheet-like shapes. Each connector 32 can include a first part 321 and a second part 322 connected to each other. The first part 321 is located outside the cavity 11, and the end of the first part 321 facing away from the second part 322 is fixedly connected to the handle 31. The second part 322 is connected to the magnetic component 20 and can move up and down within the cavity 11 and the through hole 120. When the handle 31 is not lifted, the second part 322 is located within the through hole 120 and the cavity 11; when the handle 31 is lifted, the second part 322 can pass through the through hole 120 such that at least a portion of the second part 322 is located outside the cavity 11.

[0034] Furthermore, the connector 32 also includes a protrusion 323. The protrusion 323 is located at the junction of the first portion 321 and the second portion 322, and is located outside the cavity 11. The protrusion 323 is disposed around the first portion 321 and protrudes from the surface of the first portion 321. The protrusion 323 can cover the through hole 120, preventing the first portion 321 from entering the through hole 120 or the cavity 11.

[0035] In some embodiments, such as Figure 3 As shown, the second part 322 has a recess 324, in which the magnetic component 20 is engaged. Specifically, the recess 324 can be formed by the surface portion of the second part 322 facing away from the third sidewall 16 and recessed towards the third sidewall 16. The shape of the recess 324 is adapted to the shape of the magnetic component 20. For example, when the magnetic component 20 is a permanent magnet rod (rod-shaped), the shape of the recess 324 can be semi-circular. By connecting the magnetic component 20 by forming a recess 324 on the second part 322 of the connector 32, the magnetic component 20 can be installed and removed conveniently and quickly, making the maintenance or replacement of the magnetic component 20 easier.

[0036] In some embodiments, the inner surface of the housing 10 is provided with guide grooves (not shown). When the handle 31 is lifted, the two ends of the magnetic element 20 extending in the direction of extension can move up and down within the cavity 11 along the guide grooves. The guide grooves ensure the directionality and stability of the magnetic element 20 during lifting and lowering. In this embodiment, the guide grooves are formed on the surface of the first sidewall 14 facing the second sidewall 15 and the surface of the second sidewall 15 facing the first sidewall 14, and the extension direction of the guide grooves is vertical (i.e., the arrangement direction between the top wall 12 and the bottom wall 13).

[0037] In some embodiments, such as Figures 1 to 3 As shown, the moving mechanism 40 includes wheels 41 connected to the housing 10. The number of wheels 41 can be one or more, and this application is not limited thereto. In this embodiment, there are two wheels 41, symmetrically arranged on both sides of the magnetic component 20 extending in the direction of extension (i.e., one wheel 41 is connected to the outer surface of the first sidewall 14, and the other wheel 41 is connected to the outer surface of the second sidewall 15) to ensure the stability of the demagnetizing device 100 during movement. A locking mechanism (not shown) may be provided on the wheels 41 to prevent movement of the demagnetizing device 100 when not in operation. The locking mechanism can be a component for limiting the rotation of the wheel 41 axle, and it can be mounted on the side of the wheel 41 axle.

[0038] Furthermore, the moving mechanism 40 also includes a protective cover 42. The protective cover 42 is disposed on the outer casing 10 and correspondingly positioned to cover the wheel 41. The protective cover 42 protects the wheel 41, preventing debris from tangling or clogging it, thus ensuring smooth movement. The material of the protective cover 42 may be, but is not limited to, PP. In this embodiment, the cross-section of the protective cover 42 is "7"-shaped, and the protective cover 42 covers the top and sides of the wheel 41.

[0039] In some embodiments, such as Figure 1 and Figure 4 As shown, the demagnetizing device 100 also includes an operating mechanism 50, which includes a connecting portion 51 and an operating rod 52 connected to the connecting portion 51. The connecting portion 51 is located inside the cavity 11, and the magnetic element 20 passes through the connecting portion 51 (that is, the magnetic element 20 protrudes from the connecting portion 51). The connecting portion 51 may be cylindrical, but is not limited to, one end of which may be fixed to the third side wall 16 of the outer casing 10, and the other end may be connected to the operating rod 52. The operating rod 52 extends out of the cavity 11, and may have a relatively long length, allowing the operator to easily push the demagnetizing device 100 by applying force to the operating rod 52.

[0040] Furthermore, the inner surface of the connecting part 51 may be provided with an external thread 511, and the outer surface of the operating rod 52 may be provided with an internal thread (not shown) that is compatible with the external thread 511. By engaging the external thread 511 and the internal thread, a reliable connection between the connecting part 51 and the operating rod 52 can be achieved, and the disassembly of the operating rod 52 can also be facilitated.

[0041] The demagnetizing device 100 provided in this embodiment of the application, by setting up a magnetic component 20, a handle 31, and a connector 32, allows the operator to simply lift the handle 31, which causes the magnetic component 20 to move upward within the cavity 11 of the outer casing 10. Metal impurities adsorbed at the bottom of the outer casing 10 will automatically fall off due to the weakening of the magnetic attraction, or can be easily removed by a gentle touch or scrape from the operator. The demagnetization method is simple and highly efficient. Furthermore, the outer casing 10, handle 31, and connector 32 are made of PP, eliminating the risk of metal contamination caused by metal wear. PP material is lightweight, and since the magnetic component 20 is housed within the cavity 11 of the outer casing 10, the demagnetizing device 100 will not adhere to other equipment or walls, making operation safer, more convenient, and less strenuous. PP material is corrosion-resistant and easy to clean, reducing maintenance costs.

[0042] The above description describes some specific embodiments of this application, but in actual applications, the application should not be limited to these embodiments. For those skilled in the art, other modifications and alterations made based on the technical concept of this application should fall within the protection scope of this application.
