Description

Technical Field

[0001] The utility model belongs to the technical field of demagnetization, and particularly relates to a demagnetization trolley capable of demagnetizing both sides. Background Art

[0002] In the field of battery cathode materials, there are extremely high requirements for the number of metal particles and the content of magnetic substances.

[0003] Currently, magnetic adsorption is generally used to remove magnetic foreign matter. However, existing demagnetization devices usually can only adsorb magnetic foreign matter on one side (such as the bottom surface), and the adsorption amount of magnetic foreign matter is limited. Moreover, the magnetic suction force is fixed, and it may be impossible to adsorb larger magnetic foreign matter; all of these affect the demagnetization efficiency to a certain extent.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further details the present utility model through the drawings and embodiments. Through these descriptions, the features and advantages of the present utility model will become more clearly defined. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Such as Figures 1 to 4As shown in the figure, the present utility model discloses a demagnetization trolley capable of demagnetizing both sides, which includes a pusher, a demagnetization box hinged and assembled with the pusher, pulleys 7 installed on the demagnetization box, and magnetic rods 14 inserted and assembled with the demagnetization box. When it is necessary to adsorb foreign objects, magnetic rods are installed on the demagnetization box. When it is necessary to remove the foreign objects adsorbed on the demagnetization box, the magnetic rods are removed to make the demagnetization box in a demagnetized state. In this embodiment, the demagnetization box includes a demagnetization box body 8 with an open top and a cover plate 16. A groove is provided at the top of the demagnetization box body, and the cover plate is fitted and embedded with the groove. The cover plate is fixedly connected to the demagnetization box body through cover plate fixing bolts 17. During the application process, by opening the cover plate, the insertion state of the magnetic rods can be checked. In addition, it is beneficial to replace the magnetic rods. It can be understood that a cover plate handle 18 is provided on the cover plate to facilitate the lifting of the cover plate.

[0030] In this embodiment, the pusher includes a main bracket and a grip 2. The main bracket includes a cross beam 5 and side arms 6 provided at both ends of the cross beam. Both sides of the demagnetization box are respectively hinged to the corresponding side arms through rotating shafts 10. More specifically, the rotating shafts are fixedly connected to the demagnetization box, pass through the corresponding side arms and are rotatably hinged to the corresponding side arms. A locking nut 9 is threadedly connected to the end of the rotating shaft away from the demagnetization box. Adopting this hinged form is beneficial to installation and disassembly.

[0031] A sleeve 3 is provided on the cross beam. A plurality of sleeve limiting holes 301 are spaced along the length direction on the side wall of the sleeve. The grip is inserted and assembled with the sleeve and is fixed to the sleeve through a bolt assembly 4 passing through one of the sleeve limiting holes. A grip lateral limiting hole 202 for inserting and assembling the bolt assembly is provided on the grip. By passing the bolt assembly through different sleeve limiting holes, the lifting of the grip can be realized, so as to adapt to different users. A rubber sleeve 1 is provided at the hand-held end of the grip to improve the comfort of use.

[0032] On the inner wall of the demagnetization box facing the insertion of the magnetic rods, a magnetic metal guide sleeve 11 for guiding the insertion of the magnetic rods is provided. The magnetic metal guide sleeve generates a magnetic attraction force with the corresponding magnetic rod, which can not only make the magnetic rod accurately inserted, but also ensure the stability of the magnetic rod during the demagnetization work after the two are magnetically fixed.

[0033] A plurality of magnetic rods are inserted and assembled in the demagnetization box at intervals side by side. The number and positions of the magnetic metal guide sleeves correspond to those of the magnetic rods one by one. A magnetic rod connecting frame 12 is arranged in the demagnetization box. The outer ends of the plurality of magnetic rods are connected through a magnetic rod fixing frame 15. In this way, a magnetic rod group is formed, which is convenient for the overall installation and disassembly of the magnetic rods. It can be understood that the magnetic rods can be detachably connected to both the magnetic rod connecting frame and the magnetic rod fixing frame to facilitate the replacement of single magnetic rods. In addition, a handle can be provided on the magnetic rod fixing frame to facilitate the installation of the magnetic rod group.

[0034] A through hole communicating with the sleeve is formed in the cross beam, and a grip insertion hole 13 is formed in the front side wall of the demagnetization box. A forward limiting hole 201 of the grip is formed in the grip. When not in use, the demagnetization box is turned over and folded, and the grip is inserted into the grip insertion hole along the through hole. At the same time, the grip is rotated to align the forward limiting hole of the grip with the corresponding sleeve limiting hole, and then the grip is fixed by a bolt assembly passing through the sleeve limiting hole and the forward limiting hole of the grip. In this way, the demagnetization box can be stably maintained in the folded state, thereby reducing the overall volume of the demagnetization trolley and facilitating carrying.

[0035] In this application, four pulley brackets are symmetrically and fixedly arranged on the front and rear side walls of the demagnetization box, and pulleys are installed on each pulley bracket, which is beneficial to improving the smoothness of the movement of the demagnetization box.

[0036] In this application, ten 12000GS magnetic rods are arranged in parallel and at intervals in the demagnetization box. The ten magnetic rods form a magnetic rod group, which is connected into a whole by a non-magnetic magnetic rod connecting frame to meet the conditions for use as a whole. At the same time, it is ensured that a single magnetic rod can be freely replaced to adjust the magnetism. In addition, the adjustment of the number of magnetic rods can also adjust the overall magnetic attraction. The conversion between the magnetization and demagnetization of the demagnetization box body is completed by assembling and disassembling the magnetic rod group, so as to realize the adsorption and collection of magnetic foreign matters.

[0037] In this application, the pulley is a solid rubber wheel, the used magnetic rod is neodymium iron boron coated with 304 stainless steel on the surface, and the Gauss value ≥ 12000GS. The material of the push handle is aluminum alloy, and the end of its grip is protected by a rubber sleeve. The bolts and nuts used in the demagnetization trolley are all standard parts and are adapted according to requirements.

[0038] The main structure of the demagnetization trolley in this application is the demagnetization box. Four pulleys are also included for use with the demagnetization box, which are symmetrically distributed on both sides of the demagnetization box. The inside of the demagnetization box uses a replaceable magnetic rod group, either individually or as a whole, as the main working structure for demagnetization. At the same time, a magnetic metal guide sleeve is arranged inside the demagnetization box to ensure that each magnetic rod can move forward along a predetermined route when entering and exiting. When in use, the demagnetization ability of the demagnetization trolley is adjusted by using magnetic rods with different magnetisms. By applying an external force to the demagnetization trolley to make it move in the workshop, magnetic foreign matters in the area passed through are removed. When a large amount of magnetic foreign matters are adsorbed on the bottom surface of the demagnetization box, the demagnetization box is manually turned over so that its top surface faces down, and the top surface is used to adsorb magnetic foreign matters, realizing the two-sided use of the demagnetization trolley, which greatly improves the effective working area and demagnetization efficiency of the demagnetization trolley. When the demagnetization trolley needs to be cleaned, the magnetic rod group is manually pushed and pulled to convert the magnetization and demagnetization of the demagnetization box, and then the demagnetization trolley is cleaned. Its structure is simple, the operation is convenient, and the demagnetization efficiency is high.

[0039] In this embodiment, the demagnetizing box is an overall rectangular hollow shell made of aluminum alloy as the main material. The demagnetizing box mainly serves as a support for the magnetic rod group. To achieve the support function, a magnetic metal guide sleeve is provided inside the demagnetizing box body to facilitate the horizontal movement of the magnetic rod group. At the same time, it is adsorbed by magnetic force to play a role in fixing the magnetic rod group and ensuring the stability during use. The plane of the magnetic rod group is horizontally equidistant from the bottom surface of the demagnetizing box body. The demagnetizing ability of the demagnetizing trolley is adjusted by changing the Gauss value of a single magnetic rod (neodymium iron boron surface coated with 304 stainless steel, Gauss value ≥ 12000 GS) or the magnetic rod group, and also by changing the number of magnetic rods. A cover plate made of aluminum alloy is used on the upper part of the demagnetizing box body and fixed by cover plate fixing bolts to form an integral body with the demagnetizing box body. A cover plate handle is designed on the upper part of the cover plate for easy installation and disassembly of the cover plate.

[0040] In this embodiment, it moves through four pulleys connected to the demagnetizing box body. The four pulleys can be of different sizes. By replacing the pulley sizes, the distance between the demagnetizing box body and the working surface can be adjusted to change the demagnetizing effect.

[0041] In summary, for the demagnetizing trolley of this application, a replaceable magnetic rod group, either individually or as a whole, is used inside the demagnetizing box body as the main working structure for demagnetization. At the same time, a magnetic metal guide sleeve is provided inside the demagnetizing box body to ensure that the magnetic rod group can move forward along a predetermined route every time it enters and exits. The bolt assembly passes through different sleeve limiting holes to enable the lifting of the handle, thus adapting to different users. The demagnetizing trolley involved in this application has the characteristic of double-sided use, enabling it to have a larger demagnetizing area. It is convenient to carry through a folding design. This application is used for adsorbing and removing magnetic foreign objects existing in the battery material workshop, with low cost, high removal efficiency, simple structure, easy operation, small floor space, and easy to store and organize.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
