Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a lithium battery pole piece iron removal device for automatically cleaning magnetic bar iron powder. Background Art

[0002] During the production of lithium battery pole pieces, a coating machine coats the stirred slurry on a metal foil. The coated pole pieces are then dried in an oven. The dried pole pieces are then rolled into a roll by a winding mechanism and transferred to subsequent sections for processing. The quality of the coating directly determines the performance and safety of the battery product. The coating machine has a complex and large structure, and its internal components wear out during movement, generating iron powder. The metal foil before coating easily carries this iron powder, leaving it on the pole piece along with the slurry during coating. After drying with the slurry, this iron powder is not easy to remove. Pole pieces with residual iron powder can easily pierce the diaphragm inside the lithium battery, affecting the life and safety of the lithium battery. To solve this problem, it is necessary to remove iron from the metal foil before pole piece coating to ensure that the produced pole pieces and lithium batteries are sufficiently safe.

[0003] The existing iron removal solution is to set a magnetic bar inside the coating machine. The magnetic bar is set close to one side of the pole piece and parallel to the tape running direction of the pole piece. When the metal foil passes through the magnetic bar, the iron powder and magnetic powder carried by the metal foil will be magnetically attracted and removed by the magnetic bar. After long-term use, thicker iron powder and magnetic powder will accumulate on the surface of the magnetic bar. These thicker iron powders affect the magnetic lines of force of the magnetic bar, which reduces the effect of the magnetic bar in removing iron powder. It is necessary to stop the machine and clean the magnetic bar. However, the installation position of the magnetic bar is inside the coating machine, and the magnetic bar cannot be easily removed for cleaning, which makes it difficult to clean the magnetic bar. The cleaning is not thorough, affecting the iron removal effect of the magnetic bar. Utility Model Content

[0029] The specific implementation of the present utility model is introduced with reference to the accompanying drawings.

[0030] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of a lithium battery pole piece iron removal device that automatically cleans magnetic rod iron powder. The entire device can be set at different positions of the coating machine, and can perform iron removal operations on metal foil before coating and pole piece 101 after coating. It can also be set in any process flow between the coating process and the winding process of the pole piece 101 to perform iron removal operations on the pole piece 101; wherein, the entire device is centered on the magnetic rod 1 and is arranged in parallel along the magnetic rod 1. Rotating components 2 are set on both sides of the magnetic rod 1, and a cleaning component 3 is set in parallel at the lower end of the magnetic rod 1, and the magnetic rod 1 is cleaned by the cleaning component 3.

[0031] refer to Figures 1 to 7 , a lithium battery pole piece iron removal device for automatically cleaning magnetic rod iron powder, includes a magnetic rod 1, a rotating component 2, and a cleaning component 3. The magnetic rod 1 is installed on the rotating component 2 and is arranged parallel to one side of the pole piece 101 walking path. The cleaning component 3 is arranged on one side of the magnetic rod 1. The magnetic rod 1 is provided with at least one iron removal magnetic surface 12. The rotating component 2 drives the magnetic rod 1 to rotate, so as to drive the iron removal magnetic surface 12 to switch between the iron removal position 102 and the cleaning position 103. The iron removal position 102 is set close to the pole piece 101, and the cleaning position 103 is set away from the pole piece 101; in the iron removal position 102, the iron removal magnetic surface 12 attracts the iron powder carried on the pole piece 101 by magnetic force to perform magnetic attraction and iron removal operation on the pole piece 101; in the cleaning position 103, the iron removal magnetic surface 12 cooperates with the cleaning component 3, and the cleaning component 3 wipes the iron removal magnetic surface 12 through the wiping block 31 to clean the iron powder adsorbed on the iron removal magnetic surface 12.

[0032] The iron removal device for lithium battery pole piece 101 that automatically cleans iron powder of magnetic rod 1 of the embodiment of the present application performs iron removal operation on pole piece 101 in the conveying path through magnetic rod 1 that is arranged in close parallel on one side of the conveying path of pole piece 101. The magnetic rod 1 is driven to rotate by rotating component 2 to switch the iron removal magnetic surface 12 between the iron removal position 102 and the cleaning position 103. The iron removal magnetic surface 12 with accumulated iron powder is cleaned by cleaning component 3, which facilitates the cleaning of magnetic rod 1 and enables magnetic rod 1 to maintain good magnetic force for iron removal operation.

[0033] In order to be able to clean the magnetic rod 1 without stopping the coating equipment, in this embodiment, reference Figures 1 to 3 The cross section of the magnetic bar 1 is a square. The magnetic bar 1 is provided with four ferromagnetic surfaces 12, and the ferromagnetic surfaces 12 are rectangular planes.

[0034] It can be understood that, by setting it in this way, the ferromagnetic surface 12 is set as a rectangular plane, and the four ferromagnetic surfaces 12 of the magnetic rod 1 can be switched in turn, so that the magnetic rod 1 can perform iron removal and cleaning operations at the same time, and the cleaning of the ferromagnetic surface 12 can be completed without stopping the coating machine; wherein, in addition to the square cross-section, the magnetic rod 1 can also be a regular hexagonal cross-section or a regular octagonal cross-section, and the corresponding ferromagnetic surfaces 12 are six and eight, and the ferromagnetic surfaces 12 are all rectangular planes.

[0035] In order to ensure that the iron removing magnetic surface 12 can better remove the iron from the pole piece 101, in this embodiment, reference Figure 3 The iron removal magnetic surface 12 at the iron removal position 102 is parallel to the pole piece 101 .

[0036] It can be understood that with such an arrangement, the iron removal magnetic surface 12 at the iron removal position 102 is parallel to the pole piece 101, which can ensure that the pole piece 101 passes through a larger magnetic field area and ensure that the iron removal magnetic surface 12 can magnetically absorb as much iron powder on the pole piece 101 as possible.

[0037] In order to drive the magnetic rod 1 to rotate, in this embodiment, referring to the figure, the rotating assembly 2 includes a rotating driving member 21, a cam 22, and a positioning rod 23. The two rotating driving members 21 are arranged at both ends of the magnetic rod 1. The cam 22 is fixed to the driving end of the rotating driving member 21 and is fixed to the magnetic rod 1 through the fixing seat 11. The rotating driving member 21 is connected to the guide rail 25 through the slider 24. A positioning rod 23 is provided on the outside of the cam 22. The positioning rod 23 is provided with a positioning contact 231 that contacts the cam surface 221 of the cam 22. The rotating driving member 21 drives the cam 22 and the magnetic rod 1 to rotate. During the rotation process of the cam 22 relative to the positioning rod 23, the cam surface 221 and the positioning contact 231 cooperate to push the rotating driving member 21 and the magnetic rod 1 to move along the guide rail 25 to limit the magnetic rod 1 and the iron powder on the de-ferromagnetic surface 12 from contacting the pole piece 101 during rotation.

[0038] It should be further explained that the positioning rod 23 is fixed to one side of the rotating drive member 21 through a positioning seat 29. The setting direction of the positioning rod 23 is parallel to the guide rail 25, so that the positioning contact 231 of the positioning rod 23 and the cam surface 221 can be along the direction of the guide rail 25, thereby pushing the rotating drive member 21 and the magnetic rod 1 to move along the guide rail 25. The guide rail 25 and the pole piece 101 are perpendicular to each other in the running direction, so that when the iron removal magnetic surface 12 is switched, the magnetic rod 1 is driven away from the pole piece 101. The gap between the iron removal magnetic surface 12 and the pole piece 101 on the iron removal position 102 is controlled by adjusting the length of the positioning rod 23 extending from the positioning seat 29.

[0039] It is understandable that, with such an arrangement, since the magnetic bar 1 is square, during the rotation of the magnetic bar 1, the edges of the magnetic bar 1 and the iron powder near the edges are easy to contact the pole piece 101, thereby causing the iron powder to stick back to the pole piece 101, resulting in the failure of the pole piece 101 to remove iron. Through the cooperation of the cam 22 and the positioning rod 23, the rotation of the magnetic bar 1 is completed without the iron powder on the magnetic bar 1 and the iron removal magnetic surface 12 touching the pole piece 101. At the same time, it also ensures that the distance between the iron removal magnetic surface 12 of the magnetic bar 1 at the iron removal position 102 and the pole piece 101 meets the working requirements of magnetic attraction and iron removal.

[0040] In order to cooperate with the rotation of the magnetic bar 1, in this embodiment, reference Figures 1 to 5 The cam 22 is in the shape of a square, and the cam surfaces 221 on the four sides of the cam 22 are arranged as arc surfaces concave toward the center, and the cam surfaces 221 at the corners are convex outwards.

[0041] It can be understood that, with such a configuration, the magnetic bar 1 is square, and the distance between the edge and the pole piece 101 needs to be controlled when the magnetic bar 1 rotates. By adopting a square cam 22, the rotation of the magnetic bar 1 can be coordinated to a large extent. When the positioning contact 231 of the positioning rod 23 contacts a corner of the cam 22, a corresponding edge of the magnetic bar 1 is facing the pole piece 101, so that during the rotation of the magnetic bar 1, the distance between the edge and the pole piece 101 will not be less than the distance between the iron removal magnetic surface 12 and the pole piece 101 during the iron removal operation, thereby preventing the edge of the magnetic bar 1 and iron powder from contacting the pole piece 101.

[0042] In order to make the cam surface 221 and the positioning contact 231 fit tightly, in this embodiment, reference Figures 1 to 5 The rotary driving member 21 is connected to a guide rod 26, and the guide rod 26 and the guide rail 25 are arranged parallel to each other. A limit seat 27 is installed at the end of the guide rod 26, and the guide rod 26 is slidably connected to the limit seat 27. A spring 28 and an adjustment plate 4 are sleeved on the guide rod 26. The two ends of the spring 28 respectively abut against the rotary driving member 21 and the adjustment plate 4. An adjusting screw 41 is provided on the limit seat 27, and the adjusting screw 41 is connected to the adjustment plate 4. The adjusting screw 41 adjusts the elastic force of the spring 28 by adjusting the distance between the adjustment plate 4 and the limit seat 27.

[0043] It can be understood that, in such a setting, the spring 28 is installed through the guide rod 26, and the rotary drive member 21 is pushed toward the positioning rod 23 through the elastic force of the spring 28, so that the cam surface 221 of the cam 22 is in close contact with the positioning contact 231 of the positioning rod 23. The elastic force of the spring 28 is adjusted by the adjusting plate 4 and the adjusting screw 41. The elastic force of the spring 28 is adjusted according to the rotation of the cam 22 to ensure that the rotary drive member 21 can smoothly drive the cam 22 to rotate relative to the positioning rod 23, avoid getting stuck during rotation, and avoid the cam 22 from jumping relative to the positioning rod 23 during rotation.

[0044] In order to facilitate the rotation of the magnetic bar 1, in this embodiment, Figure 5 , the rotary driving member 21 is a rotary cylinder.

[0045] It can be understood that with such a configuration, the rotary cylinder uses compressed air as a power source, which is simple to control and can easily drive the magnetic rod 1 to rotate. The rotary cylinder of the embodiment of the present application rotates 90° at a time, is simpler in structure, and is very suitable for compact installation locations.

[0046] In order to clean the magnetic bar 1, in this embodiment, refer to Figure 1 、 Figure 3 、 Figure 6 and Figure 7 The cleaning assembly 3 includes a wiping block 31, a wiping drive member 32, a mounting seat 33, and a rodless cylinder 34 connected in sequence. The wiping block 31 is installed at the driving end of the wiping drive member 32, and the wiping drive member 32 is fixed on the mounting seat 33. The mounting seat 33 is connected to the slide 35 of the rodless cylinder 34. The rodless cylinder 34 is arranged parallel to one side of the magnetic rod 1. The rodless cylinder 34 is connected to the rotating drive member 21 through the support seat 5. When cleaning the magnetic rod 1, the wiping drive member 32 drives the wiping block 31 to move to the cleaning position 103. The wiping block 31 contacts the ferromagnetic surface 12 of the magnetic rod 1 at the cleaning position 103, and the rodless cylinder 34 drives the wiping block 31 to move in a straight line along the magnetic rod 1 to wipe the ferromagnetic surface 12 of the cleaning position 103.

[0047] It can be understood that, with such a setting, the wiping block 31 is driven by the wiping drive 32 to move closer to or away from the magnetic rod 1 to avoid the rotation of the magnetic rod 1, and the wiping block 31 is driven by the rodless cylinder 34 to move and wipe along the ferromagnetic surface 12 to wipe off the iron powder on the ferromagnetic surface 12, ensuring that the iron powder on the magnetic rod 1 will not accumulate excessively, so that the ferromagnetic surface 12 of the magnetic rod 1 can be used continuously without the need for the coating machine to be stopped for cleaning.

[0048] In order to better clean the magnetic rod 1, in this embodiment, refer to Figure 3 and Figure 6 , the shape of the wiper 31 is C-shaped.

[0049] It can be understood that with such a setting, the cross-section of the magnetic rod 1 is square, and the three ferromagnetic surfaces 12 can be wiped at the same time by the C-shaped wiper 31, so that each ferromagnetic surface 12 is cleaned three times by the wiper 31 during the cleaning operation cycle. Each time cleaning is performed, the wiper 31 will be driven by the rodless cylinder 34 to move back and forth along the ferromagnetic surface 12 once, ensuring that the magnetic rod 1 can be better cleaned.

[0050] In order to optimize the structure of the cleaning component 3, in this embodiment, reference Figure 6 and Figure 7 The wiping drive member 32 is a linear cylinder, and the mounting seat 33 is in an L-shape.

[0051] It should be further explained that a waste box for mobile phone iron powder can be set between the magnetic rod 1 and the rodless cylinder 34. The iron powder wiped and cleaned by the magnetic rod 1 through the wiper 31 can fall into the waste box. The L-shaped mounting seat 33 can provide more space for the waste box to ensure that the waste box can receive the fallen iron powder well.

[0052] It can be understood that, in such a setting, the wiping drive member 32 adopts a linear cylinder, and the linear cylinder adopts compressed air as a power source. When wiping the magnetic rod 1, the linear cylinder pushes the wiping block 31 close to the magnetic rod 1. The wiping block 31 can be installed in a position horizontally facing the magnetic rod 1 through the L-shaped mounting seat 33, which facilitates the iron powder wiped off the ferromagnetic surface 12 of the cleaning position 103 to fall off.

[0053] In the embodiment of the present application, the pole piece 101 in the tape is removed by a magnetic rod 1 which is arranged in close parallel to one side of the tape path of the pole piece 101. The magnetic rod 1 is driven to rotate by the rotating component 2 to switch the iron removal magnetic surface 12 between the iron removal position 102 and the cleaning position 103. During the switching process, the cam 22 and the positioning rod 23 cooperate to prevent the magnetic rod 1 and the iron powder on the iron removal magnetic surface 12 from contacting the pole piece 101 during the rotation process, thereby ensuring the iron removal effect of the pole piece 101. The magnetic rod 1 is cleaned by the cleaning component 3, so that the magnetic rod 1 can maintain a good magnetic force for iron removal.

[0054] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
