[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0043] Example 1
[0044] This embodiment provides a pole piece dust cleaning device, which can avoid the risk of short circuit inside the core package, improve safety performance, and reduce safety hazards.
[0045] like Figures 1-4As shown, the electrode dust cleaning device mainly includes a housing 100, an air suction assembly, a first air blowing assembly 200, and a second air blowing assembly 300. The housing 100 has an inner cavity 150. Along the first direction, two opposite sides of the housing 100 are provided with through holes 110 for transmitting the electrode 10, and the through holes 110 are connected to the inner cavity 150. Along the second direction, two opposite sides of the housing 100 are provided with air suction ports 120, and the air suction assembly is connected to the air suction ports 120.
[0046] The first blowing assembly 200 and the second blowing assembly 300 are both disposed in the inner cavity 150. A channel 140 for transporting the electrode 10 is formed between the first blowing assembly 200 and the second blowing assembly 300. The channel 140 is connected to the through-hole 110, so that the electrode 10 can be transported from one through-hole 110 through the channel 140 and out of the other through-hole 110. The first blowing assembly 200 and the second blowing assembly 300 are both disposed along a third direction, with the first direction, the second direction, and the third direction being perpendicular to each other. The first blowing assembly 200 and the second blowing assembly 300 are both configured to blow air away dust on the electrode 10; the suction assembly is configured to suck the blown dust.
[0047] Based on the above design, in this embodiment, the first blowing assembly 200 and the second blowing assembly 300 can both blow air to the pole piece 10 transmitted to the channel 140, so that the dust and other metal chips and foreign matter on the pole piece 10 can be blown away, preventing foreign matter from sticking to the pole piece 10; the suction assembly can suck the blown dust, thereby removing the dust from the pole piece 10, avoiding the risk of dust and other metal chips and foreign matter entering the core package and causing a short circuit in the core package, thereby improving safety, reducing safety hazards, and saving costs.
[0048] It can be understood that during the blowing process, positive pressure areas are formed at the first blowing component 200 and the second blowing component 300; during the suction process, negative pressure areas are formed at the suction components, so that dust and other metal chips and foreign matter can be sucked out under the action of the pressure difference.
[0049] In addition, in this embodiment, the electrode 10 is transported along a first direction, the suction assembly is arranged along a second direction, and the first blowing assembly 200 and the second blowing assembly 300 are arranged along a third direction. This ensures that the electrode dust cleaning device does not affect the transport of the electrode 10 during the blowing and suction processes, thereby ensuring production efficiency and saving costs. At the same time, the internal structure of the electrode dust cleaning device can be rationally arranged, making the electrode dust cleaning device compact and miniaturized.
[0050] The first direction is Figure 1 The X-axis direction in the second direction is Figure 1 The Y-axis direction in the third direction is Figure 1 The Z-axis direction.
[0051] like Figure 1-Figure 2 As shown, the first blowing assembly 200 and the second blowing assembly 300 in this embodiment are arranged opposite to each other, which can improve the efficiency of cleaning dust on the pole piece 10 and save costs; at the same time, it can also improve the stability and reliability of the pole piece dust cleaning device and facilitate assembly.
[0052] like Figure 1 As shown, in this embodiment, along the third direction, air blowing ports 130 are provided on opposite sides of the housing 100. The first air blowing assembly 200 is in communication with one of the air blowing ports 130, and the second air blowing assembly 300 is in communication with the other air blowing port 130. One end of the two air blowing ports 130 away from the inner cavity 150 is in communication with a positive pressure pump, so that the positive pressure pump can provide positive pressure gas to the first air blowing assembly 200 and the second air blowing assembly 300, so as to ensure that dust on the pole piece 10 is blown away and prevented from adhering to the pole piece 10.
[0053] In this embodiment, the first blowing assembly 200 and the second blowing assembly 300 have the same structure, which facilitates processing and manufacturing and saves costs.
[0054] Specifically, if Figure 1-Figure 2 As shown, the first blowing assembly 200 includes a connecting pipe 210 and a blowing platform 220. A blowing hole 240 is provided on the blowing platform 220. One end of the connecting pipe 210 is connected to the blowing port 130, and the other end is connected to the blowing hole 240. The blowing hole 240 is connected to the inner cavity 150. In this way, the positive pressure pump can blow the gas from the blowing port 130 into the connecting pipe 210, and then blow it from the connecting pipe 210 to the blowing hole 240 of the blowing platform 220, and finally blow it out from the blowing hole 240 to the pole piece 10. The provision of the connecting pipe 210 can, on the one hand, connect to the blowing hole 240, and on the other hand, support the blowing platform 220 to a certain height, thereby minimizing the distance between the blowing hole 240 and the pole piece 10 as much as possible, so that the blown gas can have as much force as possible to ensure that the dust on the pole piece 10 is blown away.
[0055] Furthermore, a groove 230 is provided on the blowing platform 220. The groove 230 has a groove bottom 2301 and a groove wall 2302 that are adjacent to each other. The blowing holes 240 are provided in the groove bottom 2301. The groove bottom 2301 can be configured as a plane, and the groove wall 2302 can be configured as a plane or an arc. Preferably, the groove wall 2302 is configured as an arc, and the groove wall 2302 is curved and extends in a direction away from the groove bottom 2301. This can play a certain role in guiding the blown gas, increase the contact area between the gas and the electrode 10, and improve the efficiency of the gas in blowing away dust. The groove bottom 2301 is configured as a plane to facilitate the arrangement of the blowing holes 240.
[0056] Optionally, the grooves 230 and connecting tubes 210 in this embodiment are both provided in plurality, and the grooves 230 and connecting tubes 210 are provided in one-to-one correspondence, and a plurality of blowing holes 240 are provided at equal intervals in each groove 230, thereby increasing the gas flow rate and improving the cleaning efficiency of the dust on the electrode 10.
[0057] Optionally, the blowing holes 240 in this embodiment can be configured as circular holes, square holes, or holes of other shapes.
[0058] like Figure 3-Figure 4 As shown, along the first direction, multiple grooves 230 are staggered, so that the time for blowing gas and dust on the pole piece 10 can be increased as much as possible during the transmission of the pole piece 10 in the channel 140, ensuring that the dust on the pole piece 10 can be blown away, improving work efficiency, and ensuring the safety of the core package.
[0059] like Figure 1 As shown, the air inlet 120 in this embodiment is provided with an outer edge 1201 along the second direction, and the outer edge 1201 is connected to the air inlet assembly. The provision of the outer edge 1201 can improve the convenience and reliability of the connection between the air inlet assembly and the air inlet 120, and reduce or avoid the risk of the air inlet assembly falling off.
[0060] Optionally, the air suction component in this embodiment includes a negative pressure pump (not shown in the figure).
[0061] This embodiment also provides a battery processing device, which includes a pole piece cutting device and the above-mentioned pole piece dust cleaning device. The pole piece dust cleaning device is located upstream or downstream of the pole piece cutting device, so that the pole piece dust cleaning device can clean both the pole piece 10 before cutting and the pole piece 10 after cutting, thereby improving the cleaning effect, avoiding residual dust in the core package, and improving the safety and reliability of the core package.
[0062] Since the battery processing equipment has the above-mentioned electrode dust cleaning device, the battery processing equipment can avoid the risk of short circuit inside the core pack, improve safety performance, and reduce safety hazards.
[0063] Example 2
[0064] like Figure 5-Figure 6 As shown, this embodiment provides a pole piece dust cleaning device, which mainly differs from the first embodiment in that the bottom 2301 of the groove 230 in this embodiment is arc-shaped, and the blowing hole 240 is arranged on the groove wall 2302, so that the gas blown out of the blowing hole 240 can not only be guided by the arc-shaped groove wall 2302, but also by the arc-shaped groove bottom 2301, thereby increasing the basic area of the gas and the pole piece 10, and improving the cleaning efficiency of the dust on the pole piece 10.
[0065] The remaining structures of the electrode dust cleaning device in this embodiment are the same as those in the first embodiment and will not be described in detail here.
[0066] This embodiment also provides a battery processing equipment, which includes a pole piece cutting device and a pole piece dust cleaning device in this embodiment. The pole piece dust cleaning device is located upstream or downstream of the pole piece cutting device, so that the pole piece dust cleaning device can clean both the pole piece 10 before cutting and the pole piece 10 after cutting, thereby improving the cleaning effect, avoiding residual dust in the core package, and improving the safety and reliability of the core package.
[0067] Since the battery processing equipment has the above-mentioned electrode dust cleaning device, the battery processing equipment can avoid the risk of short circuit inside the core pack, improve safety performance, and reduce safety hazards.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
