[0029] The features and performance of the battery pole piece dust removal device of the application are further described in detail below in conjunction with the embodiments.
[0030] Example 1
[0031] As Figure 1 , Figure 2 and Figure 3As shown, the battery pole piece dust removal device provided by the embodiment of the application is used for removing dust from the surface of the battery pole piece 100 transported around and through the two conveying rollers 140. The battery pole piece dust removal device comprises a base 110 arranged below the battery pole piece 100 and two bottom support plates 120 respectively connected to the top of the base 110. A dust removal channel 130 for the battery pole piece 100 to pass through is formed between the base 110 and the two bottom support plates 120. A front brush dust removal mechanism, a gas dust removal mechanism and a rear brush dust removal mechanism are arranged in the dust removal channel 130 and are spaced apart along the length direction of the battery pole piece 100.
[0032] The front brush dust removal mechanism and the rear brush dust removal mechanism have the same structure. Therefore, the front brush dust removal mechanism is taken as an example for description. The front brush dust removal mechanism comprises two fixed horizontal rods 200 arranged above and below the battery pole piece 100 respectively. The two ends of each fixed horizontal rod 200 are connected to the adjacent side of the two bottom support plates 120 through buckles respectively. A brush 210 for cleaning the surface of the battery pole piece 100 is detachably connected to the bottom of each fixed horizontal rod 200 through a bolt.
[0033] The gas dust removal mechanism comprises dust removal plates 300 arranged above and below the battery pole piece 100 respectively. The two ends of each dust removal plate 300 are connected to the adjacent side of the two bottom support plates 120 through buckles respectively. Dust removal holes 310 aligned with the upper surface and the lower surface of the battery pole piece 100 are arranged on the bottom of the upper dust removal plate 300 and on the top of the lower dust removal plate 300 respectively. Air ducts 320 in communication with the corresponding dust removal holes 310 are arranged in the dust removal plates 300 respectively. The air ducts 320 of the two dust removal plates 300 are connected with air blowers 330 through hoses respectively. The cross sections of the air ducts 320 of the upper dust removal plate 300 decrease from top to bottom in sequence. The cross sections of the air ducts 320 of the lower dust removal plate 300 decrease from bottom to top in sequence. A dust suction pipe 340 is arranged on each side of each dust removal hole 310. Dust suction holes 350 spaced apart along the length direction of the dust suction pipe 340 are arranged on the dust suction pipe 340. Suction nozzles 390 are connected to the dust suction holes 350. The dust suction pipe 340 is connected with a suction device 360 through a hose. The suction device 360 is a suction pump.
[0034] The working principle of the battery pole piece dust removal device provided by the embodiment of the application is as follows: two rotating horizontally arranged conveying rollers 140 are used to drive the battery pole piece 100 to move along the length direction through the dust removal channel 130 formed between the base 110 and the two support plates 120 for the battery pole piece 100 to pass through, so that the battery pole piece 100 passes through the front brush dust removal mechanism, the gas dust removal mechanism and the rear brush dust removal mechanism in sequence. When the battery pole piece 100 passes through the front brush dust removal mechanism, the four brushes 210 connected with the two fixed horizontal rods 200 arranged above and below the battery pole piece 100 of the front brush dust removal mechanism clean the upper surface and the lower surface of the battery pole piece 100 respectively. Subsequently, the battery pole piece 100 passes through the two upper and lower arranged dust removal plates 300 of the gas dust removal mechanism, so that the air blower 330 respectively passes air into the air ducts 320 of the two dust removal plates 300 through the hoses, and then sprays the air out of the two dust removal holes 310 to spray and blow the upper surface and the lower surface of the battery pole piece 100, so that the dust on the upper surface and the lower surface of the battery pole piece 100 is separated, and at the same time, the air is sucked out from the two sides of the dust removal holes 310 of the dust removal plates 300 through the respective suction nozzles 390, the respective dust suction holes 350 and the dust suction pipes 340 respectively, so as to separate and suck out the dust separated from the surface of the battery pole piece 100 to realize dust removal. Finally, the battery pole piece 100 after the spraying and dust removal treatment passes through the rear brush dust removal mechanism, so that the four brushes 210 connected with the two fixed horizontal rods 200 arranged above and below the battery pole piece 100 of the rear brush dust removal mechanism clean the upper surface and the lower surface of the battery pole piece 100 respectively, so as to realize the overall cleaning work of the battery pole piece 100.
[0035] In the embodiment, the cross sections of the air ducts 320 of the upper dust removal plates 300 decrease from top to bottom in sequence, and the cross sections of the air ducts 320 of the lower dust removal plates 300 decrease from bottom to top in sequence, so that when the air blower 330 respectively passes air into the air ducts 320 of the two dust removal plates 300 through the hoses and then sprays the air out of the two dust removal holes 310, the air sprayed out of the dust removal holes 310 is subjected to pressure boosting treatment by the air ducts 320 with varying cross sections to improve the spraying and dust removal effect.
[0036] Embodiment 2
[0037] As Figure 4 and Figure 5As shown, this application provides a battery electrode dust removal device, which has a structure that is roughly the same as the battery electrode dust removal device provided in embodiment 1. The difference is that in this embodiment, arc-shaped dustproof plates 370 are connected to both sides of the dust removal plate 300. The dust removal plate 300 and the two corresponding dustproof plates 370 enclose to form a suction chamber 380 covering the corresponding dust removal hole 310 and suction pipe 340. The bottom of the upper dustproof plate 370 and the top of the lower dustproof plate 370 are respectively hinged to a fixing seat 420 by a rotating shaft 410. The rotating shaft 410 extends along the width direction of the battery electrode 100. The fixing seat 420 is provided with a slot 430, and a brush strip 400 for cleaning the surface of the battery electrode 100 is engaged in the slot 430.
[0038] The battery electrode dust removal device provided in this application embodiment has arc-shaped dustproof plates 370 connected to both sides of the dust removal plate 300. The dust removal plate 300 and the two corresponding dustproof plates 370 enclose a suction chamber 380 covering the corresponding dust removal hole 310 and suction pipe 340. When the gas blown from the dust removal hole 310 blows up the dust on the surface of the battery electrode 100, the two dustproof plates 370 can block it, preventing the blown gas from blowing the dust in all directions and causing secondary pollution. This ensures that the air pump draws the air containing dust from both sides of the dust removal hole 310 of the dust removal plate 300 through each suction nozzle 390, each suction hole 350 and suction pipe 340 for dust removal.
[0039] The dustproof plate 370 is hinged to a fixed base 420 via a pivot 410. The bottom of the fixed base 420 is provided with a slot 430, which holds a brush strip 400 for cleaning the surface of the battery electrode 100. The brush strip 400 connected to the dustproof plate 370 can be used to clean the dust on the surface of the battery electrode 100. When the brush strip 400 needs to be replaced after long-term use, the fixed base 420 can be rotated around the pivot 410 to remove the brush strip 400 from the slot 430. The new brush strip 400 can be inserted into the slot 430 and the fixed base 420 can be rotated in the opposite direction to use the new brush strip 400 to clean the surface of the battery electrode 100.
[0040] Example 3
[0041] like Figure 6 As shown, this application embodiment provides a battery electrode dust removal device, which has a structure that is generally the same as the battery electrode dust removal device provided in embodiment 1. The difference is that in this embodiment, the gas dust removal mechanism also includes two pairs of baffles 440. Each dust removal plate 300 has a baffle 440 on both sides. The two ends of each baffle 440 are connected to two support plates 120 respectively. The bottom of each baffle 440 is provided with a baffle brush 450 for cleaning the corresponding surface of the battery electrode 100. One support plate 120 has an opening 460. The support plate 120 is hinged with a closed door 470 that can be rotated to open and close the opening 460.
[0042] The battery pole piece dust removal device provided by the embodiment of the application is provided with a baffle 440 on each side of each dust removal plate 300, which can isolate the two upper and lower arranged dust removal plates 300 of the gas dust removal mechanism by using the two baffles, so that the air blower 330 respectively passes air into the air ducts 320 of the two dust removal plates 300 through the hoses and then sprays out through the two dust removal holes 310 to spray and blow the upper surface and the lower surface of the battery pole piece 100, so that the dust on the upper surface and the lower surface of the battery pole piece 100 is separated, and the two baffles 440 are used to block the dust separated by the gas spraying, so as to avoid secondary pollution caused by the dispersion of the dust.
[0043] In addition, each baffle 440 is provided with a baffle brush 450 for cleaning the corresponding surface of the battery pole piece 100, which can use the baffle brush 450 to clean the dust on the upper surface and the lower surface of the battery pole piece 100; the support plate 120 is provided with an opening 460 and a closing door 470 which can be rotated to open and close the opening 460, which can facilitate the operator to rotate the closing door 470 to open the opening 460 and then maintain and clean the inside of the dust removal channel 130.
[0044] The above described embodiments are part of the embodiments of the application, but not all the embodiments. The detailed description of the embodiments of the application is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application.
