DETAILED DESCRIPTION

[0026] In order to make the purpose, method scheme and advantages of the embodiments of the present application more clear, the method scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0027] In the whole production process of the battery, the material needs to be cleaned of environmental pollution or fine metal impurities contained therein. The original method is to install a strong magnet on a magnetic attraction device on a production line, and the material is automatically separated by the strong magnetic force when passing through. However, the magnet needs to be cleaned after being filled with metal residues. The production line needs to be stopped for cleaning each time, and then the magnet needs to be disassembled, cleaned, reinstalled, and adjusted. It takes about half an hour to complete a set of processes, and the production line needs to be stopped for cleaning at least once per shift. Such operation is labor-intensive, time-wasting, and causes great loss to the production due to the stoppage of the production line. Therefore, the installation plate of the magnet is flipped to clean the impurities on the magnet, and then the magnet is flipped back to its original position. Such operation is simpler, but the convenience of flipping the magnet and the stability of the magnet after being reset affect the use of the device. For example, in order to ensure the stability of the installation plate after being reset, the installation plate is fixed by bolts to maintain the horizontal state, but the bolts need to be disassembled for flipping and cleaning, which is relatively cumbersome. In addition, the magnet has a certain weight, and it is relatively laborious to flip it. Therefore, the applicant expects to improve the structure to solve the above problems, so that the magnet can be flipped conveniently and the stability of the magnet after being reset can be ensured. The specific embodiments are shown below.

[0028] Embodiment 1: As shown in Figures 1-2 , a magnetic attraction mechanism convenient for quick flipping includes an installation plate 1, a limiting shaft 2, and a side plate 3. The installation plate 1 is used to connect with a magnet 11. The side wall of the installation plate 1 is provided with the limiting shaft 2. The installation plate 1 is provided with one side plate 3 on each side. The installation plate 1 is rotationally connected with the side plate 3 through a rotating shaft 4. The side plate 3 is provided with an arc-shaped notch 301. The center of the arc-shaped notch 301 corresponds to the rotating shaft 4. A first elastic member 5 and a reciprocating block 6 are provided. One end of the first elastic member 5 is connected with the side wall of the arc-shaped notch 301. The other end of the first elastic member 5 is connected with the reciprocating block 6. When the first elastic member 5 is in a natural state, the reciprocating block 6 abuts against the side wall of the limiting shaft 2. The reciprocating block 6 is located on the side of the limiting shaft 2 away from the bottom wall of the arc-shaped notch 301. When the installation plate 1 rotates around the rotating shaft 4, the movement path of the limiting shaft 2 includes an arc-shaped notch segment.

[0029] In the specific implementation process, the installation plate 1 can be connected with the magnet 11 through bolts as shown in Figure 1 . The central axis of the installation plate 1 refers to the central axis extending along the length of the installation plate 1 as shown in Figure 1 . The first elastic member 5 can be a spring, and a spring mounting hole can be provided on the side wall of the arc-shaped notch 301. The reciprocating block 6 can be as shown in Figure 2As shown, when the reciprocating block 6 is in contact with the limiting shaft 2, the reciprocating block 6 still has a part in the opening, avoiding the reciprocating block 6 from being squeezed into the opening after being squeezed.

[0030] When the installation plate 1 is turned over, the reciprocating block 6 is squeezed into the opening, thereby leaving space for the limiting shaft 2 to move upward, so that the installation plate 1 can continue to turn over. When the installation plate 1 is reset by turning over, the reciprocating block 6 is squeezed again, leaving space for the limiting shaft 2 to move downward. When the limiting shaft 2 moves to the bottom wall of the arc-shaped notch 301, the reciprocating block 6 can have two states. One is that the reciprocating block 6 is in contact with the limiting shaft 2 under the action of the rebound force of the first elastic member 5, locking the limiting shaft 2. The other is that the reciprocating block 6 restores to the natural state under the action of the rebound force of the first elastic member 5, and the reciprocating block 6 is located above the limiting shaft 2, limiting the upward movement of the limiting shaft 2.

[0031] Example 2: In order to further improve the stability of the reciprocating block 6 locking the limiting shaft 2, the embodiment 1 is improved as shown in Figure 1 As shown, in this embodiment, the rotating shaft 4 and the limiting shaft 2 are arranged on the two sides of the central axis of the installation plate 1.

[0032] In the specific implementation process, if the rotating shaft 4 is located in the middle of the side wall of the installation plate 1, since the weight of the impurities adsorbed on the surface of the magnet 11 is not uniform, it is difficult to ensure that the deflection forces on the two sides of the rotating shaft 4 are strong or weak. If the rotating shaft 4 and the limiting shaft 2 are located on the same side of the central axis, it will cause the deflection force of the part of the installation plate 1 on the other side of the central axis on the rotating shaft 4 to be greater. The above two cases may cause the reciprocating block 6 to be subjected to upward force when the magnet 11 is in working state, and the locking stability of the reciprocating block 6 is weakened. Therefore, the rotating shaft 4 and the limiting shaft 2 are arranged on the two sides of the central axis at least has the advantage of ensuring the locking stability of the reciprocating block 6 on the limiting shaft 2. The rotating shaft 4 deviates from the central axis of the installation plate 1, which makes the turning operation more labor-saving, and the limiting shaft 2 and the rotating shaft 4 support the installation plate 1 more stably.

[0033] Example 3: In order to further improve the convenience of turning over, the embodiment 1 is improved as shown in Figure 2 As shown, in this embodiment, the reciprocating block 6 and the limiting shaft 2 are both arc-shaped at the end of mutual contact.

[0034] In the specific implementation process, the reciprocating block 6 can be Figure 2 As shown, it is provided as a spherical type. The existence of the arc surface on the reciprocating block 6 causes the limiting shaft 2 to squeeze the reciprocating block 6, so that the reciprocating block 6 is subjected to not only the vertical force but also the horizontal force, so as to compress the first elastic member 5, and make the reciprocating block 6 give way to the movement of the limiting shaft 2. The limiting shaft 2 can be provided as a cylindrical type.

[0035] Example 4: In order to better adjust the distance between the magnet and the adsorbed object, the embodiment 1 is improved as shown in Figures 1-2 In this embodiment, it also includes an adjusting plate 7, a fixing plate 8 and a second elastic member 9. The adjusting plate 7 is connected to the side plate 3 away from the mounting plate 1. The adjusting plate 7 is connected to the fixing plate 8 through a bolt. The fixing plate 8 is spaced apart from the adjusting plate 7 in the vertical direction. The second elastic member 9 is sleeved on the bolt and is located between the adjusting plate 7 and the fixing plate 8 in a compressed state.

[0036] In the implementation process, the fixing plate 8 can be installed on the flow line equipment, and the second elastic member 9 can be a spring. Because different use scenarios have different installation height requirements for the magnet 11, this embodiment sets the adjusting plate 7 on the side plate 3. By screwing the bolt, the distance between the adjusting plate 7 and the fixing plate 8 can be adjusted. The fixing plate 8 is installed on the flow line equipment and does not change position. Therefore, the position of the adjusting plate 7 changes, and the height of the mounting plate 1 changes. The second elastic member 9 can reduce the stress on the threads of the bolt and increase the installation stability of the adjusting plate 7.

[0037] Example 5: In order to realize the overturning limiting and better clean the impurities adsorbed on the magnet 11, the embodiments 1-4 are improved as shown in Figures 1-2 In this embodiment, it also includes a limiting block 10. The limiting block 10 is connected to the side plate 3 and is located on the side of the pivot 4 of the mounting plate 1. During the rotation of the mounting plate 1, at least one state is in abutment with the limiting block 10.

[0038] In the implementation process, the limiting block 10 can be as shown in Figure 1 The height is higher than the pivot 4, and it can also be as shown in Figure 2 Connected to one end of the side plate 3 in the length direction and in an L shape. When cleaning the magnet 11, the mounting plate 1 is overturned so that the mounting plate 1 is lapped on the limiting block 10. At this time, the position of the mounting plate 1 is stable and the whole is inclined. The cleaning operation is simpler, and the adsorbed objects on the surface of the magnet 11 are also easy to slide down along the inclined surface.

[0039] Example 6: This embodiment provides a magnetic attraction device as shown in Figures 3-7 It includes two magnetic attraction mechanisms. The mounting surfaces of the mounting plates 1 of the two magnetic attraction mechanisms are oppositely arranged in the longitudinal direction and are staggered in the transverse direction.

[0040] In the implementation process, the mounting surface of the mounting plate 1 refers to the surface connected with the magnet 11. When the upper and lower surfaces of the material need to be cleaned by the strong magnetic magnet, the magnetic attraction device provided in the embodiment can be used, which is provided with two magnetic attraction mechanisms provided in any one of the embodiments 1-5. The upper magnetic attraction mechanism is responsible for cleaning the metal impurities on the upper surface of the material, and the lower magnetic attraction mechanism is responsible for cleaning the metal impurities on the lower surface of the material. However, since the magnetic attraction mechanism needs to be flipped during cleaning, the two magnetic attraction mechanisms are arranged in a staggered manner as shown in Figure 7 , so that one of the magnetic attraction mechanisms is not hindered by the other magnetic attraction mechanism during the flipping operation.

[0041] Embodiment 7: In order to make the spacing adjustment range between the two magnets 11 larger and reduce the size of the device, the embodiment 6 is improved, as shown in Figure 3 and Figure 6 , in the embodiment, the opening end of the arc-shaped notch 301 of the upper magnetic attraction mechanism faces upward, and the opening end of the arc-shaped notch 301 of the lower magnetic attraction mechanism faces downward.

[0042] In the implementation process, if the upper and lower magnetic attraction mechanisms are flipped upward when cleaning is needed, the spacing of the two magnetic attraction mechanisms in the horizontal and vertical directions needs to be larger. The flipping space of the mounting plate 1 in the lower magnetic attraction mechanism is given up, the size of the device is larger, and the minimum distance between the two magnets can also be larger, which reduces the applicability. In addition, when the limiting shaft 2 and the rotating shaft 4 are arranged on the central axis, the part of the mounting plate 1 flipped upward is larger than the part flipped downward, which further increases the minimum distance between the two magnetic attraction mechanisms.

[0043] Embodiment 8: In order to further avoid the mutual interference of the two magnetic attraction mechanisms, the embodiment 7 is improved, as shown in Figure 3 and Figure 6 , in the embodiment, the rotating shaft 4 of the upper magnetic attraction mechanism is farther away from the lower magnetic attraction mechanism in the horizontal direction than the limiting shaft 2; and the rotating shaft 4 of the lower magnetic attraction mechanism is farther away from the upper magnetic attraction mechanism in the horizontal direction than the limiting shaft 2.

[0044] In the implementation process, since part of the mounting plate 1 rotates upward and part of the mounting plate 1 rotates downward during flipping, the mutual interference between the two mounting plates 1 can be reduced if the rotating directions are opposite. In the embodiment, when the upper magnetic attraction mechanism is flipped, the part of the upper mounting plate 1 close to the lower mounting plate 1 rotates upward, as shown in Figure 3 . In the embodiment, when the lower magnetic attraction mechanism is flipped, the part of the lower mounting plate 1 close to the upper mounting plate 1 rotates downward, as shown in Figure 6, the part of the lower mounting plate 1 close to the upper mounting plate 1 rotates downward. The limiting block 10 corresponding to the lower magnetic attraction mechanism can be used to support the mounting plate 1 after it is turned over, and keep the inclination of the mounting plate 1. In the lower magnetic attraction mechanism, the mounting plate 1 rotates downward, so that it can rotate faster under the action of gravity, and the inertia causes the turning angle to be too large, so the limiting block 10 corresponding to the lower magnetic attraction mechanism is mainly used to prevent the mounting plate 1 from turning over too much.

[0045] Example 9: In order to better install the magnet 11, on the basis of example 6, it is improved as shown in Figure 4 In this embodiment, it also includes: a magnet 11, the magnet 11 includes: a functional block 1101 and a connecting block 1102, one connecting block 1102 is arranged at each end of the functional block 1101, the connecting block 1102 is connected with the mounting plate 1, and the thickness of the functional block 1101 is greater than that of the connecting block 1102.

[0046] In the specific implementation process, the functional block 1101 mainly provides magnetic force for adsorbing metal impurities. Because the thickness of the functional block 1101 is large, it is not convenient to be directly connected with the mounting plate 1. Therefore, the connecting block 1102 with small thickness is used to realize the installation of the magnet 11 in this embodiment. The connecting block 1102 can have magnetism or not. When the connecting block 1102 and the functional block 1101 are a whole magnet, the connecting block 1102 with small thickness can also increase the distance between the connecting block 1102 and the metal impurities, so as to avoid that too many impurities are adsorbed on the connecting block 1102. Because the surface of the connecting block 1102 is not flat due to the existence of the bolt, it is not convenient to clean.

[0047] Example 10: In order to prevent installation from being not in place, on the basis of examples 6-9, it is improved as shown in Figure 2 Or Figure 5 In this embodiment, it also includes: a travel switch 12, the travel switch 12 is connected with the side plate 3 close to the side of the magnet 11, and the height of the travel switch 12 is less than that of the limiting shaft 2.

[0048] In the specific implementation process, the travel switch 12 is an electrical control device used for detecting the position or travel end point of a mechanical moving part. In the process of rotating the mounting plate 1 to the horizontal state, when it moves to the preset position and contacts the travel switch 12, it is determined that the mounting plate 1 moves to the position. If the mounting plate 1 does not move to the position, and the cleaning operation of the magnet 11 on the metal impurities on the surface of the material continues, the staff can be prompted by alarm.

[0049] The above merely is preferred embodiment of the present utility model, and is not used to limit the present utility model, for the method personnel in the art, the present utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the present utility model, should be contained in the protection scope of the present utility model.
