Description

Technical Field

[0001] The utility model relates to the technical field of power battery winding, in particular to a dust removal device. Background Art

[0002] The cells of power batteries need to go through a winding process during production and processing. The winding process refers to the process of stacking the positive electrode sheet, negative electrode sheet and diaphragm, and then winding them to form a cell. The positive electrode sheet and the negative electrode sheet are collectively referred to as the electrode sheet. The outer surface of the electrode sheet is coated with an active layer, which causes the electrode sheet to produce a certain amount of dust particles during the winding, transportation and cutting process. At the same time, there are also dust particles in the external environment. These particles will be rolled into the cell during winding, and it is easy to pierce the diaphragm and cause a short circuit, so a dust removal device is needed to remove dust from the electrode sheet before winding.

[0003] Existing dust removal devices all use rotating brushes to sweep dust from the pole piece. Some of the swept particles will be discharged from the dust removal device with the airflow, and some particles will stick to the brush surface or be mixed in the brush. Long-term use will affect the dust removal effect on the pole piece. The existing solution is to manually disassemble and clean the brush regularly, which is cumbersome and time-consuming, affecting the dust removal and winding efficiency. Utility Model Content

[0047] See also Figures 1 to 5, is a dust removal device 100 of an embodiment of the utility model, comprising a housing 10, a dust sweeping assembly 20 and a dust shaking assembly 30. A cavity 15 is provided in the housing 10, and the cavity 15 forms a space for dust removal of the pole piece 90, thereby reducing the leakage of dust. The dust sweeping assembly 20 comprises a mounting seat 21, a brush 22 and a rotating driving member 23; the mounting seat 21 is slidably arranged in the housing 10; the brush 22 is rotatably connected to the mounting seat 21, and the brush 22 is arranged in the cavity 15, and the brush 22 is used to perform dust removal operation on the surface of the pole piece 90; the rotating driving member 23 is connected to the brush 22 to drive the brush 22 to rotate, thereby realizing the dust removal operation of the brush 22. The dust shaking assembly 30 includes a top support member 31, an elastic member 32 and a stop block 33; the top support member 31 is connected to the outer shell 10, and the top support member 31 drives the mounting seat 21 to move away from the stop block 33; the elastic member 32 is respectively connected to the outer shell 10 and the mounting seat 21; the stop block 33 is fixedly connected to the outer shell 10, and the setting position of the stop block 33 corresponds to the mounting seat 21. Among them, the top support member 31 overcomes the elastic force of the elastic member 32 itself to push the mounting seat 21 to move, and the mounting seat 21 drives the brush 22 to move together; when the top support member 31 is separated from the mounting seat 21, the mounting seat 21 hits the stop block 33 under the elastic force generated by the elastic member 32 restoring its own deformation, and the impact load generated by the collision is transmitted to the brush 22, thereby shaking off the particles attached to and mixed with the brush 22, so as to achieve self-cleaning of the brush 22.

[0048] Furthermore, the housing 10 is in a hollow rectangular shape, and the cavity 15 is arranged in a rectangular shape in the housing 10. The housing 10 is provided with a feed port 11 and a discharge port 12; the feed port 11 and the discharge port 12 are arranged on both sides of the housing 10 in a first direction, and the feed port 11 and the discharge port 12 are both connected to the cavity 15. The feed port 11 is used to send the pole piece 90 into the cavity 15 for dust removal, and the discharge port 12 is used to send the pole piece 90 after dust removal from the cavity 15. In this embodiment, the feed port 11 and the discharge port 12 are symmetrically arranged relative to the housing 10, so that the pole piece 90 passes through the housing 10 in a straight line direction, thereby avoiding dead angles in the dust removal process of the pole piece 90, and ensuring the dust removal effect of the pole piece 90.

[0049] Furthermore, the number of dust sweeping assemblies 20 is multiple, and the multiple dust sweeping assemblies 20 are symmetrically arranged on both sides of the feed port 11 along the second direction to ensure that the dust sweeping assemblies 20 perform dust removal operations on both sides of the pole piece 90 at the same time to ensure dust removal efficiency.

[0050] Furthermore, the mounting seat 21 is slidably disposed in the housing 10, and the mounting seats 21 in the dust sweeping assembly 20 on both sides of the feed port 11 are close to or away from each other. The brush 22 is cylindrical, and the brush 22 can be rotatably connected to the mounting seat 21. The brush 22 moves together with the mounting seat 21, and the mounting seat 21 drives the brushes 22 on both sides of the feed port 11 to approach or move away from each other, thereby achieving a synchronous dust removal operation on both sides of the pole piece 90. The rotating drive member 23 is connected to the mounting seat 21, and the rotating drive member 23 moves together with the mounting seat 21. The rotating drive member 23 is disposed on the outside of the housing 10, and the rotating drive member 23 is used to provide the torque required for the brush 22 to rotate. In the present embodiment, the same dust sweeping assembly 20 includes one brush 22, and the number of the dust sweeping assemblies 20 is two. The two dust sweeping assemblies 20 are symmetrically arranged on both sides of the feed port 11. Therefore, two brushes 22 are arranged in the housing 10, and the two brushes 22 are symmetrically arranged on both sides of the feed port 11 along the second direction. Considering the connection stability of the brush 22, the mounting seat 21 is respectively arranged at both ends of the brush 22. In another embodiment, the same dust sweeping assembly 20 includes a plurality of brushes 22, and the plurality of brushes 22 in the same dust sweeping assembly 20 are arranged at intervals along the first direction. By arranging the brushes 22 at intervals in the first direction, a multi-point dust removal operation of the electrode 90 is achieved, thereby improving the dust removal effect. Of course, it is understandable that in order to achieve the purpose of arranging a plurality of brushes 22 at intervals along the first direction, a plurality of groups of dust sweeping assemblies 20 may be arranged, and each dust sweeping assembly 20 is arranged at intervals along the first direction. At this time, the brushes 22 are symmetrically arranged on both sides of the feed port 11 along the second direction to perform synchronous dust removal operations on both sides of the pole piece 90 to ensure dust removal efficiency; the brushes 22 are arranged at intervals along the first direction to perform multi-point dust removal operations on the same side of the pole piece 90 to ensure dust removal effect.

[0051] Furthermore, the mounting seat 21 includes a bearing portion 211 and a sliding portion 212. The bearing portion 211 is in a rectangular block shape, and the brush 22 is rotatably connected to the bearing portion 211; the sliding portion 212 is in a strip shape, and the sliding portions 212 are relatively arranged on both sides of the bearing portion 211 in the first direction, and one end of the sliding portion 212 away from the bearing portion 211 is movably connected to the housing 10, so that the mounting seat 21 can be slidably arranged in the housing 10. In this embodiment, a slide rail is arranged between the slide portion 212 and the housing 10, and the slide rail is fixed to the housing 10 along the second direction, and the slide portion 212 is slidably arranged on the slide rail, so that the mounting seat 21 can move relative to the housing 10 along the second direction.

[0052] Furthermore, in the moving direction of the mounting seat 21 relative to the housing 10, the width dimension of the bearing portion 211 is D1 mm, and the width dimension of the sliding portion 212 is D2 mm. Among them, D1>D2. That is, in the second direction, the width of the bearing portion 211 is greater than the width of the sliding portion 212. By making the width dimension of the bearing portion 211 greater than the width dimension of the sliding portion 212, the local bearing capacity of the mounting seat 21 at the position of the bearing portion 211 is improved, and at the same time, there is no need to widen the mounting seat 21 as a whole to improve the bearing capacity, thereby saving the material cost used in processing the mounting seat 21.

[0053] Furthermore, the top support member 31 and the stop block 33 are arranged on the same side of the bearing portion 211, and the top support member 31 is connected and fixed to the housing 10. The top support member 31 is used to push the mounting seat 21 to press the brush 22 against the pole piece 90. The stop block 33 is in the shape of a long strip and extends from the housing 10 toward the bearing portion 211. The stop block 33 and the top support member 31 are both arranged corresponding to the bearing portion 211 of the mounting seat 21, so that the loads applied by the top support member 31 and the stop block 33 to the mounting seat 21 are concentrated on the bearing portion 211. At the same time, since the bearing portion 211 is centrally designed with a structure to improve the bearing capacity, the reliability of the operation of the mounting seat 21 can be effectively guaranteed. The stop blocks 33 are relatively arranged on both sides of the top support member 31 in the first direction to ensure that the impact load applied by the stop blocks 33 to the mounting seat 21 is more balanced, avoid generating a deflection torque on the mounting seat 21, and ensure the reliability of the dust shaking operation. In this embodiment, the supporting member 31 is a pneumatic cylinder or a hydraulic cylinder. The specific structure of the supporting member 31 is not limited here. It is sufficient to ensure that the supporting member 31 can provide the power required for the movement of the mounting seat 21.

[0054] Further, the elastic member 32 is arranged on one side of the sliding portion 212 close to the supporting member 31, one end of the elastic member 32 is connected to the sliding portion 212, and the other end of the elastic member 32 is connected to the housing 10. There are multiple elastic members 32, and the elastic members 32 are respectively arranged on the sliding portions 212 located on both sides of the bearing portion 211. In this embodiment, the elastic member 32 is a tension spring, that is, when the supporting member 31 pushes the mounting seat 21 to move toward the direction close to the pole piece 90, the elastic member 32 is in a stretched state, and then after the supporting member 31 interrupts the supporting force applied to the mounting seat 21, the mounting seat 21 will hit the stop block 33 under the tension of the elastic member 32. In another embodiment, the elastic member 32 is a compression spring, and the elastic member 32 is correspondingly arranged on the side of the sliding part 212 away from the supporting member 31, that is, when the supporting member 31 pushes the mounting seat 21 to move toward the pole piece 90, the elastic member 32 is in a compressed state, and after the supporting member 31 interrupts the supporting force applied to the mounting seat 21, the mounting seat 21 will also hit the stop block 33 under the push of the elastic member 32. It can be understood that the specific arrangement position of the elastic member 32 and the working mode of whether it is a tension spring or a compression spring are not limited here, ensuring that the supporting member 31 will overcome the elastic force of the elastic member 32 in the process of driving the mounting seat 21 to move, thereby causing the elastic member 32 to produce elastic deformation, and after the supporting member 31 interrupts the force applied to the mounting seat 21, the mounting seat 21 will hit the stop block 33 under the action of the elastic member 32 restoring the elastic deformation, thereby generating an impact load to shake off the dust attached to or mixed with the brush 22.

[0055] Furthermore, the number of the dust-shaking assemblies 30 is multiple, and in the second direction, the multiple dust-shaking assemblies 30 are respectively arranged on the sides of the dust-sweeping assemblies 20 located on both sides of the feed port 11, which are away from each other. It can be understood that the dust-shaking assembly 30 can also be arranged between the dust-sweeping assemblies 20 on both sides, and the top support member 31 pushes the mounting seat 21 to move and hit the stop block 33, and the top support member 31 interrupts the support force on the mounting seat 21. The mounting seat 21 moves toward the pole piece 90 under the elastic force of the elastic member 32, so that the brush 22 contacts the pole piece 90.

[0056] Furthermore, the dust removal device 100 also includes a dust suction pipe 40. The dust suction pipe 40 is arranged on one side of the housing 10, and is used to extract the gas in the cavity 15. The dust suction pipe 40 can extract the dust swept off the pole piece 90 and the dust attached to the brush 22 with the air, and then the dust is accumulated in the cavity 15, ensuring the dust removal effect on the pole piece 90 and the dust shaking effect on the brush 22.

[0057] Furthermore, the dust removal device 100 also includes an air nozzle 50. The air nozzle 50 is arranged on a side of the housing 10 away from the dust suction pipe 40, and the air nozzle 50 is arranged opposite to the dust suction pipe 40. The air nozzle 50 is used to blow gas into the cavity 15, and then by sucking and blowing air on the opposite sides of the housing 10, a unidirectional linear airflow is formed in the cavity 15, thereby improving the dust extraction effect, and avoiding the generation of swirling airflow, which causes dust to accumulate in the cavity 15. In this embodiment, the number of the air nozzles 50 is multiple, and the multiple air nozzles 50 are arranged at intervals along the extension direction of the brush 22, so that the airflow blown by the air nozzle 50 impacts the brush 22, effectively improving the effect of shaking off the dust attached to the brush 22 and the mixed dust.

[0058] In summary, the embodiment of the utility model provides a dust removal device 100, which has the following beneficial effects:

[0059] The mounting base 21 is pushed to move by the top support member 31, and when resetting, the mounting base 21 will collide with the stop block 33 under the action of the elastic member 32. The impact load generated by the collision will be transmitted to the brush 22 connected to the mounting base 21, and then the dust particles attached to and mixed with the brush 22 will be shaken off, so that the brush 22 automatically shakes off the dust particles after each battery cell is wound, and there is no need for regular disassembly and cleaning, thereby ensuring continuous dust removal efficiency and battery cell winding efficiency.

[0060] Since the mounting seat 21 includes the bearing portion 211 and the sliding portion 212 and the width of the bearing portion 211 is greater than the width of the sliding portion 212 , the ability of the bearing portion 211 to withstand impact loads can be improved, thereby improving the reliability of the mounting seat 21 .

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
