[0027] The transportation of the cylindrical battery current collector plate welded to the bare battery cell is carried out by loading it with a cup with holes at the bottom and transporting it through the logistics line. Foreign matters generated by the wear between the chain plate of the logistics line and the cup will be electrostatically adsorbed on the end face of the battery cell, thus contaminating the end face of the battery cell.

[0028] In order to remove foreign matters and avoid contaminating the end face of the battery cell, a dust removal device is generally set on the logistics line. However, the dust removal effect of the dust removal device in the related art is poor when in use.

[0029] Based on the above considerations, in order to solve the problem of poor dust removal effect of the existing dust removal device when in use, a dust removal system is designed.

[0030] In the technical solution of the embodiments of the present application, since the air outlet of the first ventilation duct faces the logistics line, by blowing ionic wind into the first ventilation duct, the dust electrostatically adsorbed on the surface of the materials on the logistics line can be blown off. Then, the dust collector is used to remove the sundries at the gap of the logistics line to avoid the sundries at the gap of the logistics line falling on the surface of the materials. Finally, the electrostatic adsorption function of the dust removal member is used to adsorb the remaining fine dust particles on the surface of the materials, so that the dust on the materials can be effectively treated, and the overall dust removal effect is good.

[0031] According to some embodiments of the present application, Figure 4 is a schematic diagram of the dust removal member in the present application, Figure 5 is Figure 4 a schematic diagram from another perspective. As Figure 4 shown in combination with Figure 5 the present application provides a dust removal member 14, which includes a housing 11, an electrostatic adsorption roller 141, a cleaning roller 142, a connecting pin 145 and an elastic member 144. Among them, the housing 11 includes opposite side plates 112, and the side plates 112 are provided with an arc-shaped groove 114 and a second notch 1122. The electrostatic adsorption roller 141 is disposed in the housing 11; at least part of the roller core of the cleaning roller 142 passes through the second notch 1122, and the cleaning roller 142 is configured to clean the electrostatic adsorption roller 141; the connecting pin 145 is disposed in the arc-shaped groove 114, and the connecting pin 145 can slide relative to the arc-shaped groove 114; one end of the elastic member 144 is connected to the roller core of the cleaning roller 142, and the other end is connected to the connecting pin 145.

[0032] The electrostatic adsorption roller 141 in this embodiment may be composed of a roller core, a conductive layer, an insulating layer and an electrode. Among them, the conductive layer is wrapped on the surface of the roller core, the insulating layer is located on the surface of the conductive layer, and the electrodes are installed at both ends of the roller core or other specific positions for connecting a power supply to provide charge for the electrostatic adsorption roller. It should be noted that the above structure of the electrostatic adsorption roller 141 is only an example, and can be determined according to actual situations, and the embodiments of this specification do not limit this.

[0033] In this embodiment, both ends of the roller core of the electrostatic adsorption roller 141 can be correspondingly connected to the opposite two side plates 112 on the housing 11, and the electrostatic adsorption roller 141 as a whole can rotate relative to the side plates 112 around the axial direction of the roller core.

[0034] The cleaning roller 142 in this embodiment can be a tearable dust-removing roller, a sponge rubber roller, etc. Both ends of the roller core of the cleaning roller 142 are correspondingly connected to the opposite two side plates 112 on the housing 11, and the cleaning roller 142 as a whole can rotate relative to the side plates 112.

[0035] Referring to Figure 4 as shown, the cleaning roller 142 is located below the electrostatic adsorption roller 141, and at the same time, the cleaning roller 142 is in contact with the electrostatic adsorption roller 141.

[0036] In this embodiment, the elastic member 144 can refer to a member that can deform under an external force and return to its original state after the external force is removed. The elastic member 144 can be elastically compressed in the vertical direction. The elastic member 144 can be made of a metal material or a non-metal material, such as: leaf spring, helical spring, gas spring, rubber spring, etc. It can be determined according to actual situations, and the embodiments of this specification do not limit this.

[0037] The connecting pin 145 in this embodiment can be snap-fitted on the side plate 112, or the connecting pin 145 is integrally formed, which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0038] Refer to Figure 4 As shown, when the two ends of the roller core on the cleaning roller 142 pass through the second notch 1122 correspondingly and are stuck in the second notch 1122, then one end of the elastic member 144 is connected to the roller core and the other end is connected to the connecting pin 145, so that the cleaning roller 142 can be installed on the side plate 112.

[0039] The structure of the arc-shaped groove 114 in this embodiment is as Figure 4 shown. When the connecting pin 145 is at the leftmost end of the arc-shaped groove 114, at this time, after the elastic member 144 is connected to the connecting pin 145, the elastic member 144 is in a stretched state, and the cleaning roller 142 is fixed on the side plate 112 under the pulling force of the elastic member 144; When the connecting pin 145 slides from the left end to the right end in the arc-shaped groove 114, at this time, the elastic member 144 is driven by the connecting pin 145 and returns from the stretched state to the initial state. The elastic member 144 is no longer under the pulling force. In this way, there is no pulling force between the elastic member 144 and the connecting pin 145, so that the elastic member 144 can be conveniently disassembled from the connecting pin 145. After the elastic member 144 is disassembled from the connecting pin 145, the elastic member 144 is further disassembled from the roller core on the cleaning roller 142. At this time, the roller core on the cleaning roller 142 is taken out from the second notch 1122, and then the cleaning roller 142 can be disassembled from the side plate 112.

[0040] During use, through the electrostatic adsorption function carried by the electrostatic adsorption roller 141 itself, it is convenient to adsorb the fine dust particles remaining on the surface of the material. At the same time, the dust adsorbed on the electrostatic adsorption roller 141 can stick to the cleaning roller 142, so that it is convenient to clean the electrostatic adsorption roller 141.

[0042] In this embodiment, the two ends of the roller body are correspondingly connected to two opposite side plates 112 on the housing 11, and the roller body as a whole can rotate relative to the side plate 112. The adhesive layer wraps around the surface of the roller body, and the sticky side of the adhesive layer is located on the outside. In this way, by contacting the electrostatic adsorption roller 141 with the adhesive layer, the dust adsorbed on the electrostatic adsorption roller 141 will stick to the adhesive layer, so that the electrostatic adsorption roller 141 can be cleaned.

[0043] When there are a lot of debris stuck on the outermost sticky layer, the outermost sticky layer can be torn off and the next sticky layer can be used to continue working.

[0045] The connecting member 143 in this embodiment can be a bolt, an indexing pin, etc. The specific connection member 143 can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0046] The fixing sheet 115 in this embodiment can be vertically welded to the side of the side plate 112 away from the electrostatic adsorption roller 141. The side plate 112 is provided with a first notch 1121. The two ends of the roller core on the electrostatic adsorption roller 141 pass through the first notch 1121 and are stuck at the first notch 1121. The connecting member 143 is connected to the fixing sheet 115 in the vertical direction and then connected to the roller core on the electrostatic adsorption roller 141. At this time, the electrostatic adsorption roller 141 can be fixedly installed on the side plate 112.

[0047] According to some embodiments of the present application, the connecting member 143 includes an indexing pin, which is fixed to the fixing plate 115 and connected to the roller core on the electrostatic adsorption roller 141 .

[0048] In the present embodiment, the structure of the indexing pin may be an L-shaped indexing pin. When in use, the L-shaped indexing pin is threadedly connected to the fixing plate 115 and then connected to the roller core on the electrostatic adsorption roller 141, so that the electrostatic adsorption roller 141 can be quickly fixed to the side plate 112.

[0049] The present application also provides a dust removal system, such as Figures 1 - 3 As shown, the dust removal system includes a dust collector 13 and a dust removal component as any one of the embodiments of the present application, wherein a shell 11 is arranged on the bottom surface of the logistics line 10, a first ventilation duct 12 is arranged on the shell 11, and an air outlet of the first ventilation duct 12 faces the logistics line 10; the dust collector 13 is arranged on the bottom surface of the logistics line 10, and is configured to remove debris in the gap of the logistics line 10; the dust removal component 14 is arranged on the bottom surface of the logistics line 10, and is configured to electrostatically adsorb debris on the logistics line 10.

The first ventilation duct 12 can be connected to the housing 11 by bolts, or the first ventilation duct 12 is integrally formed with the housing 11. The air blown out from the first ventilation duct 12 can blow onto the materials on the logistics line 10.

[0051] The dust collector 13 in this embodiment can be a brush, a roller brush, etc. The dust collector 13 can be fixed inside the housing 11 by bolts, or the dust collector 13 is snap - connected inside the housing 11. Specifically, it can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0052] For the specific structure of the dust removal member 14 in this embodiment, refer to the above - mentioned embodiment, and details will not be described here again.

[0053] During use, since the air outlet of the first ventilation duct 12 faces the logistics line 10, by blowing ionized air into the first ventilation duct 12, the dust electrostatically adsorbed on the surface of the materials on the logistics line 10 can be blown off. Then, the dust collector 13 is used to remove the sundries in the gaps of the logistics line 10, preventing the sundries in the gaps of the logistics line 10 from falling on the surface of the materials. Finally, the electrostatic adsorption function of the dust removal member 14 is used to adsorb the fine dust particles remaining on the surface of the materials, so that the dust on the materials can be effectively treated, and the overall dust removal effect is good.

[0054] According to some embodiments of the present application, as Figure 1 and combined with Figure 4 shown, the position of the side plate 112 on the housing 11 relative to the logistics line 10 is adjustable in the first direction, where the first direction intersects with the conveying direction of the logistics line 10.

[0056] Referring to Figure 4 shown, in this embodiment, a long slot 113 is provided on the side plate 112. The long slot 113 extends along the X - axis direction. By passing bolts through the corresponding long slots 113 and connecting them to the logistics line 10, adjusting the position of the long slots 113 relative to the logistics line 10 in the X - axis direction can synchronously adjust the position of the side plate 112 relative to the logistics line 10 in the X - axis direction. At this time, the distance between the electrostatic adsorption roller 141 on the side plate 112 and the logistics line 10 in the X - axis direction can also be synchronously adjusted so that the electrostatic adsorption roller 141 can contact the bottom surface of the materials on the logistics line.

[0057] According to some embodiments of the present application, as Figure 1As shown, a second ventilation duct 15 is provided on the housing 11. The second ventilation duct 15 is located downstream of the electrostatic adsorption roller 141 along the conveying direction of the material flow line 10; the air outlet of the second ventilation duct 15 faces the material flow line 10.

[0059] During use, when the materials are dust-removed by the electrostatic adsorption roller 141, and then the second ventilation duct 15 is used to blow ion wind towards the materials, the static electricity generated on the surface of the materials due to friction can be eliminated, preventing the materials from adsorbing dust again due to the action of static electricity. According to some embodiments of the present application, the dust removal system further includes a first ion blower (not marked in the figure), and the air outlet of the first ion blower is communicated with the air inlet of the second ventilation duct 15. In this way, it is convenient to blow ion wind into the second ventilation duct 15.

The guiding surface is inclined along a first direction. The guiding surface is located around the through hole 111, and the first direction intersects with the conveying direction of the material flow line 10.

[0061] The first direction in this embodiment can refer to the description above and will not be elaborated here.

[0062] In this embodiment, the dust generated after dust removal can conveniently flow out through the through hole 111 to the outside. And the dust generated after dust removal can quickly flow to the guiding surface through the guiding surface, avoiding the dust from falling on the inner bottom surface of the housing 11.

[0063] According to some embodiments of the present application, the dust removal system further includes a second ion blower (not marked in the figure), and the air outlet of the second ion blower is communicated with the air inlet of the first ventilation duct 12; the included angle between the air outlet direction of the first ventilation duct 12 and the material flow line 10 is adjustable.

[0064] In this embodiment, a plurality of gaskets are provided between the first ventilation duct 12 and the side wall of the housing 11, and the first ventilation duct 12 and the side wall of the housing 11 are connected by bolts.

[0065] During use, refer to Figure 1As shown, by adding gaskets to the upper side of the connection between the first ventilation duct 12 and the side wall of the housing 11, or by reducing gaskets on the lower side of the connection between the first ventilation duct 12 and the side wall of the housing 11, the included angle between the air outlet direction of the first ventilation duct 12 and the material flow line 10 can be adjusted. In this way, the ion wind blown out by the first ventilation duct 12 can be made to blow towards the surface of the material.

[0066] Of course, it can be understood that the structure for adjusting the included angle between the air outlet direction of the first ventilation duct 12 and the material flow line 10 by increasing or decreasing gaskets is only an example. In other alternative solutions, a baffle can also be provided at the air outlet of the first ventilation duct 12 to adjust the air direction of the air outlet, which can be determined according to the actual situation specifically, and the embodiments of this specification do not limit this.
