[0002] During the production process of lithium battery cathode materials, the requirements for controlling the production and manufacturing environment are becoming increasingly strict. However, in the production and manufacturing workshop, due to the long-term wear of internal equipment, external air, personnel, and materials bringing in pollution sources, impurities such as metal iron filings in the pollution sources will pose a threat to battery safety. The metal particles often have magnetism and will adsorb on the material surface, resulting in an increase in the proportion of H-P short-circuit rate.

[0029] The following reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Describe the demagnetization trolley according to the embodiments of the present invention.
[0030] Refer to Figure 1As shown, the demagnetization trolley according to the embodiment of the present utility model includes a vehicle frame 100, a rotating mechanism 200, and a collection box 300.
[0031] The vehicle frame 100 includes an annular portion 110. The annular portion 110 has an inner sidewall, and the inner sidewall of the annular portion 110 encloses a middle cavity. A chute 111 is provided on the inner sidewall of the annular portion 110. The chute 111 has a conductive section 112 and a non-conductive section 113. The rotating mechanism 200 includes a rotating main shaft 210 and a rotating electromagnetic rod 220. The rotating main shaft 210 is connected to the vehicle frame 100 through a shaft support structure. One end of the rotating electromagnetic rod 220 is connected to the rotating main shaft 210. The rotating electromagnetic rod 220 is located between the chute 111 and the rotating main shaft 210. The other end of the rotating electromagnetic rod 220 is connected to the chute 111 through a conductive contact portion 230. The rotating electromagnetic rod 220 can rotate around the rotating main shaft 210. The collection box 300 is located in the middle cavity and is located below the rotating electromagnetic rod 220. The collection box 300 is arranged below the non-conductive section 113 to collect the debris falling from the rotating electromagnetic rod 220. The magnetic rod power supply 400 is electrically connected to the conductive section 112 and one end of the rotating electromagnetic rod 220 respectively. The rotating power device 500 drives the rotating main shaft 210 to rotate.
[0032] For example Figure 2 and Figure 3 As shown, the vehicle frame 100 is the main structure of the demagnetization trolley of the present utility model. The inner sidewall of the annular portion 110 encloses a middle cavity, which is equivalent to leaving a space in the middle of the annular portion 110 as the space for the rotating mechanism 200. The chute 111 of the annular portion 110 has a conductive section 112 and a non-conductive section 113. The conductive section 112 and the non-conductive section 113 of the chute 111 form a complete chute structure, and this complete chute structure is located around the inner sidewall of the annular portion 110.
[0033] For example Figure 4As shown, the rotating mechanism 200 works at the position of the middle cavity left in the annular part 110. The rotating main shaft 210 of the rotating mechanism 200 can be installed approximately vertically, while the rotating electromagnetic rod 220 can be installed approximately horizontally. The rotating electromagnetic rod 220 is controlled to rotate around the rotating main shaft 210 in an active or driven manner by the corresponding rotating power device 500. Among them, the above-mentioned active manner can be power devices in the prior art such as electric and fuel-driven ones, and the above-mentioned driven manner can be through various transmission devices, so that when the demagnetization trolley of the present invention moves, it drives the rotating electromagnetic rod 220 to rotate. The rotating electromagnetic rod 220 is connected to the sliding groove 111 through the conductive contact part 230. In this way, the sliding groove 111 can guide the conductive contact part 230 on the rotating electromagnetic rod 220 to move along the guiding range of the sliding groove 111, and further guide the rotation of the rotating electromagnetic rod 220. The rotating electromagnetic rod 220 is started by the corresponding magnetic rod power supply 400, so that the rotating electromagnetic rod 220 generates magnetic suction to adsorb iron filings. When the rotating electromagnetic rod 220 rotates to the position of the conductive section 112, the rotating electromagnetic rod 220 is in the energized state and generates magnetic suction, while when the rotating electromagnetic rod 220 rotates to the position of the non-conductive section 113, the rotating electromagnetic rod 220 is in the de-energized state and loses magnetic suction. It is equivalent that the range covered when the rotating electromagnetic rod 220 rotates through the conductive section 112 position is used as the conductive area, and the range covered when the rotating electromagnetic rod 220 rotates through the non-conductive section 113 position is used as the non-conductive area.
[0034] The collection box 300 is located below the rotating electromagnetic rod 220. The upper end of the collection box 300 is open and is used to collect the iron filings adsorbed by the rotating electromagnetic rod 220. When the rotating electromagnetic rod 220 rotates to the position of the non-conductive section 113, the rotating electromagnetic rod 220 is in the de-energized state and loses magnetic suction. In this way, the iron filings originally adsorbed on the rotating electromagnetic rod 220 fall into the collection box 300 for collection due to the loss of suction.
[0035] During actual work, while the demagnetization trolley of the present invention moves, the rotating mechanism 200 works. When the rotating electromagnetic rod 220 rotates around the rotating main shaft 210, the conductive contact part 230 remains in contact with the sliding groove 111, and the sliding groove 111 guides the rotation of the rotating electromagnetic rod 220. When the rotating electromagnetic rod 220 rotates to the position of the conductive section 112 of the sliding groove 111, the rotating electromagnetic rod 220 is in the energized state and generates magnetic suction, and the rotating electromagnetic rod 220 can adsorb iron filings. When the rotating electromagnetic rod 220 rotates to the position of the non-conductive section 113 of the sliding groove 111, the rotating electromagnetic rod 220 is in the de-energized state and loses magnetic suction, and the iron filings on the rotating electromagnetic rod 220 fall into the collection box 300 due to the loss of suction of the rotating electromagnetic rod 220.
[0036] In the above manner, the rotating electromagnetic rod 220 continuously rotates and alternately passes through the positions of the conductive section 112 and the non-conductive section 113, realizing the control of intermittent power-on and power-off of the rotating electromagnetic rod 220. It can continuously work to collect the iron filings on the ground, achieving rapid and efficient iron filings removal in the production workshop.
[0037] The way that the rotating electromagnetic rod 220 continuously rotates around the rotating main shaft 210 can also expand the working range of the rotating electromagnetic rod 220 for magnetic operations compared with the original way where the magnetic structure is fixed, improving the working efficiency of the iron filings removal work.
[0038] While the magnetic removal trolley of the present utility model is moving, the rotating mechanism 200 is performing iron filings removal work on the vehicle frame 100, so that there is no need for staff to hold the device for work. The vehicle frame 100 can be moved manually, driven by a power device, or even the travel route of the magnetic removal trolley of the present utility model can be planned by an intelligent control device. The above ways do not affect the iron filings removal work of the rotating mechanism 200.
[0039] The rotating electromagnetic rod 220 is arranged on the vehicle frame 100, so that the rotating electromagnetic rod 220 can be limited to a suitable height by the vehicle frame 100, thus avoiding the problem of wear caused by friction between the magnetic rod structure and the ground.
[0040] In some embodiments of the present utility model, the rotating electromagnetic rod 220 works through magnetoelectric conversion induction. The main body part of the rotating electromagnetic rod 220 is a thick magnetic rod, and its main body shape is the middle section of a cylinder. Both ends of the rotating electromagnetic rod 220 are fixedly clamped and connected. The main body part of the rotating electromagnetic rod 220 has a magnetic force > 6000 GS, and its working principle is electromagnetic conversion, and the magnetic force attracts target substances for adsorption.
[0041] In some embodiments of the present utility model, the rotating electromagnetic rod 220 includes a magnetic rod shaft 221 and a magnetic adsorption shaft 223. One end of the magnetic rod shaft 221 is connected to the magnetic adsorption shaft 223. The radius of the magnetic rod shaft 221 is smaller than the radius of the magnetic adsorption shaft 223. The other end of the magnetic rod shaft 221 is connected to the conductive contact part 230. The conductive contact part 230 includes a contact end 231, and the contact end 231 is inserted into the sliding groove 111, which is equivalent to the conductive contact part 230 being sleeved on the magnetic rod shaft 221 of the rotating electromagnetic rod 220. The contact end 231 of the conductive contact part 230 is inserted into the sliding groove 111, so that the contact end 231 can slide in the sliding groove 111. And the rotating electromagnetic rod 220 is powered on through the contact end 231 and the conductive section 112 of the sliding groove 111. In this way, the conductive contact part 230 can be made of a material with better conductivity to ensure the power-on operation of the rotating electromagnetic rod 220. Moreover, as a component that continuously contacts and rubs against the sliding groove 111, the conductive contact part 230 can be replaced as needed.
[0042] In some embodiments of the utility model, during the operation of the rotating electromagnetic rod 220, the conductive contact portion 230 and the magnetic rod axis 221 can be relatively fixed, or can be relatively slid or rotated for fine adjustment without affecting the operation of the rotating electromagnetic rod 220.
[0043] In some embodiments of the utility model, the conductive contact part 230 includes an outer support ring 232, which extends outward from the contact end 231. A spring 240 is mounted on the magnetic rod shaft 221. The two ends of the spring 240 are respectively in contact with the outer support ring 232 and the magnetic suction shaft 223, which is equivalent to fine-tuning the movement between the conductive contact part 230 and the magnetic rod shaft 221. The spring force is applied to the outer support ring 232 of the conductive contact part 230 by the spring 240, so that the conductive contact part 230 maintains a thrust toward the position of the slide groove 111, ensuring that the conductive contact part 230 maintains contact with the slide groove 111, thereby preventing the rotating electromagnetic rod 220 from being powered off or loosened due to insufficient contact between the conductive contact part 230 and the slide groove 111.
[0044] In some embodiments of the present invention, a clamping portion 222 is provided on the magnetic rod shaft 221 or the magnetic attraction shaft 223 of the rotating electromagnetic rod 220 , and both ends of the spring 240 abut between the outer support ring 232 and the clamping portion 222 , so that the spring 240 is firmly installed.
[0045] In some embodiments of the present invention, the conductive contact portion 230 is fixedly connected to the magnetic rod shaft 221 of the rotating electromagnetic rod 220 as a whole.
[0046] In some embodiments of the present invention, the contact end 231 is in the shape of an arcuate protrusion, and the slide groove 111 is in the shape of an arcuate groove. The arcuate protrusion of the contact end 231 matches the arcuate groove of the slide groove 111, so that the contact end 231 can contact each other more fully when inserted into the slide groove 111, and avoid the conductive contact part 230 from sliding on the slide groove 111. Figure 4 In the example, the cross section of the contact end 231 is an arc-shaped convex shape, and the cross section of the slide groove 111 is an arc-shaped concave shape.
[0047] In some embodiments of the present invention, referring to Figure 6 , the conductive segment 112 is arc-shaped, and the central angle of the arc is greater than 300° and less than 330°. The central angle of the arc is greater than 300°, which is equivalent to the conductive segment 112 covering more than five-sixths of the circular area (i.e., the conductive area area) surrounded by the chute 111, so that the rotating electromagnetic rod 220 can be ensured to have sufficient working time and magnetic suction range to ensure the efficiency of iron chip removal. The central angle of the arc is less than 330°, which is equivalent to reserving enough space for the collection box 300 to ensure that it can accommodate enough debris.
[0048] In some embodiments of the present utility model, the central angle corresponding to the arc of the conductive segment 112 is 305°, that is, the area of the conductive region accounts for about 85% of the area of the middle cavity.
[0049] In some embodiments of the present utility model, the central angle corresponding to the arc of the conductive segment 112 is 310°, that is, the area of the conductive region accounts for about 86% of the area of the middle cavity.
[0050] In some embodiments of the present utility model, the central angle corresponding to the arc of the conductive segment 112 is 315°, that is, the area of the conductive region accounts for about 88% of the area of the middle cavity.
[0051] In some embodiments of the present utility model, the central angle corresponding to the arc of the conductive segment 112 is 320°, that is, the area of the conductive region accounts for about 89% of the area of the middle cavity.
[0052] In some embodiments of the present utility model, the central angle corresponding to the arc of the conductive segment 112 is 325°, that is, the area of the conductive region accounts for about 90% of the area of the middle cavity.
[0053] In some embodiments of the present utility model, one end of the rotating electromagnetic rod 220 is fixedly connected to the lower end of the rotating main shaft 210 through the connecting end 224, and the other end of the rotating electromagnetic rod 220 is provided with a conductive contact part 230.
[0054] In some embodiments of the present utility model, when the rotating electromagnetic rod 220 is energized, it is ensured that the magnetic attraction shaft 223 has magnetism, and the conductive contact parts 230 and the connecting end 224 at both ends of the magnetic attraction shaft 223 are not required to be magnetic.
[0055] In some embodiments of the present utility model, referring to Figure 4 、 Figure 5 , the magnetic rod power supply 400 is arranged on the vehicle frame 100, a conductive slip ring 250 is arranged on the rotating main shaft 210, the conductive slip ring 250 includes a rotating part 251 and a stationary part 252, the rotating part 251 of the conductive slip ring 250 is electrically connected to the rotating electromagnetic rod 220, and the magnetic rod power supply 400 is respectively electrically connected to the conductive segment 112 and the stationary part 252 of the conductive slip ring 250. The magnetic rod power supply 400 is used to supply power to the rotating electromagnetic rod 220 to make the rotating electromagnetic rod 220 generate magnetic attraction force.
[0056] When energized, the rotating electromagnetic rod 220 conducts electricity by using the magnetic rod power supply 400, converts electric power into magnetic force, and starts to perform circular surrounding work around the rotating main shaft 210 through the rotating part 251. When the work is completed, the magnetic rod power supply 400 is turned off, the electric power disappears, and the corresponding magnetic force of the rotating electromagnetic rod 220 disappears.
[0057] The rotating electromagnetic rod 220 rotates continuously, and the conductive section 112 and the non-conductive section 113 are intermittently powered on and off, enabling the electromagnetic rod to intermittently have magnetism and not have magnetism; during the period when it has magnetism, the electromagnetic rod attracts magnetic foreign objects, and during the period when it does not have magnetism, the magnetic foreign objects fall off the electromagnetic rod.
[0058] Specifically, the positive and negative or negative and positive poles of the magnetic rod power supply 400 are respectively electrically connected to the conductive section 112 and the conductive slip ring 250 correspondingly.
[0059] The structure and working principle of the conductive slip ring 250 can refer to the conductive slip ring structure of the prior art. Since the rotating main shaft 210 rotates, the conductive slip ring 250 remains relatively stationary, which facilitates the power-on between the conductive slip ring 250 and the magnetic rod power supply 400. At the same time, the conductive section 112 of the chute 111 and the vehicle frame 100 are also relatively stationary. In this way, the magnetic rod power supply 400 can be easily electrically connected to the conductive section 112 and the conductive slip ring 250 respectively. Cooperating with the electrical connection between the conductive slip ring 250 and the rotating electromagnetic rod 220, continuous power supply to the rotating electromagnetic rod 220 by the magnetic rod power supply 400 is achieved.
[0060] In some embodiments of the present utility model, the conductive slip ring 250 can adopt the Senrui Pu H series through-hole conductive slip ring.
[0061] In some embodiments of the present utility model, the magnetic rod power supply 400 can also be arranged on the rotating mechanism 200 and rotate together with the rotating electromagnetic rod 220. Among them, the magnetic rod power supply 400 can be arranged inside or outside the rotating electromagnetic rod 220.
[0062] In some embodiments of the present utility model, the rotating power device 500 is arranged on the vehicle frame 100, a pulley 212 is arranged on the rotating main shaft 210, and the rotating power device 500 is connected to the pulley 212 through a transmission belt 510. The rotating power device 500 is used to drive the rotating electromagnetic rod 220 to rotate.
[0063] After the rotating power device 500 is started, the output shaft of the rotating power device 500 drives the transmission belt 510 to move, and then drives the pulley 212, so that the rotating electromagnetic rod 220 rotates.
[0064] In some embodiments of the present utility model, the vehicle frame 100 includes a vehicle shell part 120. There is an installation hole in the middle of the vehicle shell part 120, and the annular part 110 is sleeved inside the installation hole of the vehicle shell part 120. The vehicle shell part 120 serves as an external protection and support structure, making the structure of the vehicle frame 100 more solid and reliable, especially playing a protective role for the annular part 110 and the rotating mechanism 200.
[0065] In some embodiments of the present utility model, the shaft support structure is a support beam 130. The support beam 130 is disposed on the vehicle frame 100, and the rotating main shaft 210 is rotatably connected to the support beam 130. The support beam 130 is connected to the rotating main shaft 210 for fixing the rotating main shaft 210.
[0066] In some embodiments of the present utility model, the support beam 130 is disposed on the vehicle shell portion 120.
[0067] In some embodiments of the present utility model, a bearing is disposed between the support beam 130 and the rotating main shaft 210, and the bearing is used to guide the rotation of the rotating main shaft 210.
[0068] In some embodiments of the present utility model, a rotating shaft end cover 211 is disposed between the support beam 130 and the rotating main shaft 210, and the rotating shaft end cover 211 is used to fix the positions of both ends of the rotating main shaft 210.
[0069] In some embodiments of the present utility model, the support beam 130 includes an upper beam 131 and a lower beam 132. The upper beam 131 and the lower beam 132 are respectively disposed on the upper and lower sides of the vehicle frame 100. The upper and lower ends of the rotating main shaft 210 are respectively rotatably connected to the upper beam 131 and the lower beam 132, so that the installation of the rotating main shaft 210 is sufficiently stable and reliable, ensuring that the rotation movement process of the rotating electromagnetic rod 220 is sufficiently stable.
[0070] In some embodiments of the present utility model, the support beam 130 includes a column 133 and a cross beam 134. The column 133 is connected to the vehicle frame 100, and the cross beam 134 is connected to the rotating main shaft 210.
