Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a ground demagnetization device. Background Technology

[0002] Within lithium battery production workshops, there are sources of pollution such as dust, metal particles, and moisture. The battery manufacturing process is particularly vulnerable to the introduction of metal particles, which can adhere to the surface of battery materials and potentially cause short circuits. In lithium battery production workshops, most metal particles settle on the ground, necessitating demagnetization treatment of the floor.

[0003] Traditional demagnetization methods involve manually cleaning the floor using dust collection carts or floor scrubbers, or holding a magnetic rod close to the ground for adsorption. These methods are time-consuming and labor-intensive, and the demagnetization effect is poor, affecting production. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a ground demagnetization device that has a good demagnetization effect on the ground, and has a simple structure and is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The supporting part is connected to the frame via the connecting part. The upper pressing part is spaced above the supporting part. The magnet is located between the supporting part and the upper pressing part. The upper pressing part is connected to the supporting part via the locking member to press the magnet against the supporting part. The magnet protrudes from the bottom of the frame, and its length direction extends along a first direction. Both ends of the magnet protrude from the supporting part along the first direction, which is perpendicular to the vertical direction.

[0007] As a further embodiment of the ground demagnetization device, the locking component includes multiple screws and nuts that engage with the screws. The supporting portion is provided with two sets of hole structures spaced apart along the second direction. The magnet is located between the two sets of hole structures. Each set of hole structures includes at least two first connecting holes. The upper pressing portion is provided with multiple second connecting holes through it along the vertical direction.

[0008] As a further embodiment of the ground demagnetization device, the locking member includes a plug-in portion and a locking portion. One end of the upper pressing portion along the second direction is detachably connected to the connecting portion through the plug-in portion. The locking portion is located on the side of the magnet away from the connecting portion along the second direction. The edge of the other end of the upper pressing portion along the second direction is connected to the supporting portion through the locking portion to press the magnet against the supporting portion. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0009] As a further embodiment of the ground demagnetization device, the plug-in portion includes a plug-in block and a plug-in hole. The upper pressing portion has the plug-in block protruding on one side of the connecting portion along the second direction. The connecting portion has the plug-in hole corresponding to the plug-in block, and the plug-in block is plugged into the plug-in hole.

[0010] As a further embodiment of the ground demagnetization device, the locking part includes a plurality of screws and nuts that engage with the screws. The supporting part is provided with a set of hole structures adjacent to the edge of the supporting part along the second direction. The hole structures include a plurality of first connecting holes that penetrate the supporting part in a vertical direction. The upper pressing part is provided with a plurality of second connecting holes that penetrate in a vertical direction. The second connecting holes correspond one-to-one with the first connecting holes. The screws pass through the first connecting holes and the second connecting holes and are screwed into the nuts. The nuts abut against the upper surface of the upper pressing part.

[0011] As a further embodiment of the ground demagnetization device, the walking mechanism also includes a crash bar, which is fixed to the outer periphery of the frame and adjacent to the bottom of the frame, with the magnet located below the crash bar.

[0012] As a further embodiment of the ground demagnetization device, the length of the connecting part extends vertically, and the connecting part is fixed between the anti-collision strip and the vehicle frame.

The ground can be demagnetized as the walking mechanism moves through the wheels. Since the two ends of the magnet protrude from the support part along its length and the magnet protrudes from the bottom of the frame, the magnet can be exposed and close to the ground, which has a good demagnetizing effect on the ground.

[0031] Example 1

[0032] like Figures 1 to 3As shown, this utility model embodiment provides a ground demagnetizing device, including a walking mechanism 100 and a demagnetizing mechanism 200. The walking mechanism 100 includes a frame 110 and walking wheels (not shown in the figure). The bottom of the frame 110 is provided with a plurality of walking wheels spaced apart. The demagnetizing mechanism 200 includes a connecting part 210, a supporting part 220, an upper pressing part 230, a locking member, and a magnet 240. The supporting part 220 is connected to the frame 110 through the connecting part 210, and the upper pressing part 230 is spaced apart from the supporting part 220. Above the support portion 220, the magnet 240 is located between the support portion 220 and the upper pressing portion 230. The upper pressing portion 230 is connected to the support portion 220 by a locking member to press the magnet 240 against the support portion 220. The magnet 240 protrudes from the bottom of the frame 110, and the length direction of the magnet 240 extends along the first direction (X direction in the figure). The two ends of the magnet 240 protrude from the support portion 220 along the first direction, which is perpendicular to the vertical direction (Z direction in the figure).

[0033] In this embodiment, the support portion 220 supports the magnet 240, which is fixed to the support portion 220 by the upper pressing portion 230. The support portion 220 is connected to the frame 110 by the connecting portion 210, thereby allowing the magnet 240 to be mounted on the frame 110. The walking mechanism 100 demagnetizes the ground during walking. Since the magnet 240 protrudes from the support portion 220 at both ends along its length and protrudes from the bottom of the frame 110, the magnet 240 is exposed and closer to the ground, resulting in a better demagnetization effect on the ground.

[0034] Understandably, the upper pressure part 230 locks the magnet 240 onto the support part 220 using a locking member. After the ground demagnetization process is completed, the locking member can be released, and the magnet 240 can be removed for cleaning. The ground demagnetization device in this embodiment has a simple structure, the magnet 240 is easy to install and remove, and it does not occupy the internal space of the frame 110.

[0035] Furthermore, the locking member includes a plug-in portion and a locking portion. One end of the upper pressing portion 230 along the second direction (Y direction in the figure) is detachably connected to the connecting portion 210 through the plug-in portion. The locking portion is located on the side of the magnet 240 away from the connecting portion 210 along the second direction. The edge of the other end of the upper pressing portion 230 along the second direction is connected to the supporting portion 220 through the locking portion to press the magnet 240 against the supporting portion 220. The first direction, the second direction and the vertical direction are perpendicular to each other.

[0036] In this case, after one end of the upper pressing part 230 along the second direction is connected to the connecting part 210 through the plug-in part, the upper pressing part 230 can be pre-fixed. At this time, the edge of the other end of the upper pressing part 230 along the second direction is connected to the supporting part 220 through the locking part, so that the magnet 240 can be fixed on the supporting part 220 more quickly.

[0037] like Figure 3 As shown, the plug-in part includes a plug-in block 250 and a plug-in hole 260. The upper pressing part 230 has a plug-in block 250 protruding on one side of the connecting part 210 along the second direction. The connecting part 210 has a plug-in hole 260 corresponding to the plug-in block 250. The plug-in block 250 and the plug-in hole 260 are plugged in and engaged.

[0038] When installing the magnet 240, first place the magnet 240 on the support part 220, then align the plug 250 on one side of the upper pressing part 230 with the plug hole 260 on the connecting part 210. After the plug 250 and the plug hole 260 are plugged in and engaged, the upper pressing part 230 and the support part 220 are connected by the locking part on the other side of the upper pressing part 230, thereby fixing the magnet 240 on the support part 220.

[0039] In other embodiments, a plug hole 260 may be provided on the side of the upper pressing part 230 facing the connecting part 210 along the second direction, and a plug block 250 may be provided on the side of the connecting part 210 facing the plug hole 260, thereby realizing the plug-in engagement between the connecting part 210 and the upper pressing part 230.

[0040] In this embodiment, the locking part includes a plurality of screws 270 and nuts 280 that cooperate with the screws 270. The supporting part 220 is provided with a set of hole structures adjacent to the edge of the supporting part 220 along the second direction. The hole structures include a plurality of first connecting holes 221 that penetrate the supporting part 220 in the vertical direction. The upper pressing part 230 is provided with a plurality of second connecting holes 231 that penetrate in the vertical direction. The second connecting holes 231 correspond one-to-one with the first connecting holes 221. The screws 270 pass through the first connecting holes 221 and the second connecting holes 231 and are screwed into the nuts 280. The nuts 280 abut against the upper surface of the upper pressing part 230.

[0041] After connecting the upper pressing part 230 to the connecting part 210 along one side of the second direction via the plug-in part, only a second connecting hole 231 needs to be provided at the edge position of the upper pressing part 230 along the other side of the second direction, and a corresponding first connecting hole 221 needs to be provided on the support part 220. A corresponding screw 270 can then pass through the first connecting hole 221 and the second connecting hole 231 and be locked with a nut 280. When the nut 280 abuts against the upper surface of the upper pressing part 230, the magnet 240 can be stably fixed above the support part 220 by the upper pressing part 230. In this embodiment, the plug-in part and the locking part are combined to fix the magnet 240 to the support part 220, eliminating the need to provide locking parts on both sides of the magnet 240 along the second direction. This results in a simple structure and convenient and quick operation.

[0042] For example, the locking part includes two screws 270 and two nuts 280, and there are also two corresponding first connecting holes 221 and two second connecting holes 231. The supporting part 220 and the connecting part 210 are both cuboid structures. The two first connecting holes 221 are located at the two corners of the supporting part 220, and the two second connecting holes 231 are located at the two corners of the pressing part 230.

[0043] In this embodiment, the nut 280 is a wing nut 280, which is convenient for tightening. The screw 270 passes through the first connecting hole 221 and the second connecting hole 231 from the lower end of the support part 220 and extends to the top of the upper pressing part 230, and is then locked and fixed with the wing nut 280. The lower end of the screw 270 can be flush with or slightly protrude from the lower surface of the support part 220, which can prevent the screw 270 from colliding with other debris on the ground and affecting the installation stability of the magnet 240 and the smoothness of the walking mechanism 100.

[0044] Furthermore, the walking mechanism 100 also includes a crash bar 120, which is fixed to the outer periphery of the frame 110 and adjacent to the bottom of the frame 110, with the magnet 240 located below the crash bar 120.

[0045] In this embodiment, the anti-collision strip 120 is used to protect the frame 110. By designing and installing the magnet 240 below the anti-collision strip 120, the anti-collision strip 120 can provide a certain protective effect for the demagnetizing mechanism 200.

[0046] Furthermore, the length of the connecting part 210 extends vertically, and the connecting part 210 is fixed between the anti-collision strip 120 and the frame 110.

[0047] For example, the lower end of the connecting part 210 is vertically connected to the supporting part 220. The connecting part 210 is fixedly connected to the frame 110 by bolts. The connecting part 210 is located between the anti-collision strip 120 and the frame 110. The anti-collision strip 120 can be used to provide anti-collision protection for the connecting part 210. At the same time, the anti-collision strip 120 can be used to abut against the connecting part 210 to improve the installation stability of the connecting part 210.

[0048] In this embodiment, the connecting part 210 is fixed between the anti-collision strip 120 and the frame 110, and will not occupy the internal space of the frame 110.

[0049] Furthermore, such as Figure 4 As shown, the demagnetizing mechanism 200 also includes a rubber pad 290. The rubber pad 290 protrudes from the side of the upper pressing part 230 facing the supporting part 220 and abuts against the magnet 240.

[0050] When the upper pressing part 230 fixes the magnet 240 to the support part 220 through the locking member, the rubber pad 290 will be squeezed and fit tightly against the magnet 240, which can improve the installation stability of the magnet 240 and avoid rigid contact between the upper pressing part 230 and the magnet 240, thus preventing damage to the magnet 240.

[0051] In this embodiment, the support portion 220 is provided with a plurality of clearance holes extending vertically. By providing clearance holes, the area of ​​the magnet 240 exposed on the support portion 220 can be increased, thereby improving the demagnetizing effect of the magnet 240 on the ground.

[0052] For example, the support portion 220 has an annular square frame structure, which can maximize the area of ​​the magnet 240 exposed in the support portion 220.

[0053] In this embodiment, the walking mechanism 100 is an AGV (Automated Guided Vehicle) trolley, which automatically demagnetizes the ground by walking automatically.

[0054] Of course, in other embodiments, the walking mechanism 100 can also be a handcart.

[0055] In this embodiment, a plurality of demagnetizing mechanisms 200 are provided at intervals on the outer periphery of the frame 110.

[0056] Example 2

[0057] The ground demagnetizing device in this embodiment is basically the same as that in Embodiment 1 above (refer to the attached drawings of Embodiment 1 above, and use the same markings for the same parts), the difference being the structure of the locking element.

[0058] like Figure 5 As shown, each group of hole structures includes at least two first connecting holes 221, such as... Figure 6 As shown, the upper pressing part 230 is provided with a plurality of second connecting holes 231 through it in the vertical direction, and the second connecting holes 231 correspond one-to-one with the first connecting holes 221.

[0059] In this embodiment, the locking component includes a plurality of screws 270 and nuts 280 that cooperate with the screws 270. The support portion 220 is provided with two sets of hole structures spaced apart along the second direction. The magnet 240 is located between the two sets of hole structures. The screws 270 pass through the first connecting hole 221 and the second connecting hole 231 and are screwed into the nuts 280. The nuts 280 abut against the upper surface of the upper pressing portion 230. The first direction, the second direction and the vertical direction are perpendicular to each other.

[0060] In this embodiment, by providing connecting holes on both sides of the support portion 220 and the upper pressing portion 230 along the second direction, and by using screws 270 to pass through the corresponding connecting holes and locking them with nuts 280, a downward pressing force can be applied to the two edges of the magnet 240 along the second direction, thereby stably fixing the magnet 240 on the support portion 220.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
