Description

Technical Field

[0001] The present application relates to the technical field of battery separator production equipment, and in particular to a mist suction device and a coating system. Background Art

[0002] To ensure the spraying quality of the battery separator, the opening width of the spray head needs to be greater than the width of the separator. As a result, not all the slurry particles ejected from the opening of the spray head can adhere to the separator. Some atomized slurry will accumulate on both sides in the width direction of the separator. When the driving roller drives the separator to move, the atomized slurry on both sides of the separator will flow with the air, which may cause the atomized slurry to adhere to the driving roller or the ground behind the separator.

[0003] The prior art usually uses a mist suction device to absorb the atomized slurry on both sides of the separator. However, the width of the mist suction channel of the existing mist suction device cannot adapt to separators with different widths. When processing separators with different widths, it is necessary to replace the mist suction device with a corresponding mist suction channel width, thereby increasing the production cost.

[0039] Embodiment 1

[0040] Please refer to Figure 1 , an embodiment of the present application provides a fog absorption device 100, which is used in a coating system having a spraying device. The spraying device can spray atomized slurry on one side of the separator 400, and the fog absorption device 100 can absorb the atomized slurry on both sides of the separator 400 along the width direction.

[0041] Please refer to Figure 4 , the spraying device of this embodiment includes a driving roller 200 and a spraying head 300. The driving roller 200 is used to drive the separator 400 to move, and the spraying head 300 faces one side of the separator 400. The spraying head 300 is used to spray atomized slurry on one side of the separator 400.

[0042] The spraying head 300 has an opening, the extending direction of the opening is parallel to the width direction of the separator 400, and the width of the extending direction of the opening is greater than the width of the separator 400 to ensure the spraying quality of the separator 400. Atomized slurry will accumulate on both sides of the separator 400 along the width direction.

[0043] Please refer to Figure 1 and Figure 4 , the fog absorption device 100 includes a main body 110, a ventilation pipe 120, a suction member 140, a first baffle member 150 and a second baffle member 160.

[0044] Among them, the main body 110 is arranged on the side of the separator 400 away from the spraying head 300. The main body 110 has a cavity inside, and at least one air suction groove 111 extending along the first direction X is also opened on the main body 110. The air suction groove 111 faces the spraying head 300 and communicates with the cavity.

[0045] The extending direction of the air suction groove 111 and the width direction of the separator 400 are both the first direction X.

[0046] At least a part of the ventilation pipe 120 penetrates through the main body 110, and an air intake groove 1211 is opened on the ventilation pipe 120. The air intake groove 1211 communicates with the cavity.

[0047] The suction port of the suction member 140 is communicated with one end of the ventilation pipe 120.

[0048] The fog suction device 100 of this embodiment opens the air intake groove 1211 communicating with the cavity inside the main body 110 on the ventilation pipe 120, so that the air extraction port of the air suction member 140 can extract the gas inside the cavity, thereby generating a pressure difference inside and outside the cavity, enabling the dust and the dissipated atomized slurry on both sides of the diaphragm 400 to flow into the cavity through the air suction groove 111 along with the air, and further preventing the dissipated atomized slurry from adhering to the driving roller 200 or the ground behind the diaphragm 400 as it flows with the air. The fog suction device 100 of this embodiment can avoid adverse effects such as scratches and dents on the diaphragm 400 caused by the accumulation of slurry on the roller surface by reducing the amount of atomized slurry adhering to the driving roller 200, prevent the diaphragm 400 from being scrapped, and reduce the cleaning time due to the slurry adhering to the ground.

[0049] The first baffle member 150 and the second baffle member 160 are oppositely arranged along the first direction X outside the main body 110, and both the first baffle member 150 and the second baffle member 160 can move along the first direction X on the main body 110.

[0050] The first baffle member 150 and the second baffle member 160 moving towards each other or away from each other along the first direction X on the main body 110 can adjust the air suction width of the air suction groove 111 along the first direction X to adapt to the diaphragm 400 with different film widths.

[0051] In some embodiments, an air suction groove 111 extending along the first direction X is opened on the main body 110. When the first baffle member 150 and the second baffle member 160 move towards each other along the first direction X on the main body 110, the first baffle member 150 and the second baffle member 160 can block both ends of the air suction groove 111 to reduce the air suction width a of the air suction groove 111. When the first baffle member 150 and the second baffle member 160 move away from each other along the first direction X on the main body 110, the air suction width a of the air suction groove 111 gradually increases.

[0052] In some embodiments, please refer to Figure 1 , a plurality of air suction grooves 111 extending along the first direction X are opened on the main body 110 to improve the air intake efficiency of the fog suction device 100. The first baffle member 150 and the second baffle member 160 cooperate to be able to control the air suction width a of a plurality of air suction grooves 111 simultaneously.

[0053] In some embodiments, a plurality of air suction grooves 111 are evenly arranged along the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0054] The operator adjusts the suction width a of the suction slot 111 to be smaller than the width of the diaphragm 400 by driving the first baffle 150 and the second baffle 160 to move towards or away from each other, thereby avoiding the phenomenon of insufficient spraying.

[0055] The phenomenon of insufficient spraying means that the suction slot 111 absorbs the slurry particles that should have adhered to the surface of the diaphragm 400.

[0056] In some embodiments, the suction width a of the suction slot 111 is smaller than the width of the diaphragm 400 by 1 - 3 cm.

[0057] Preferably, when the suction width a of the suction slot 111 is smaller than the width of the diaphragm 400 by 2 cm, both the absorption effect can be ensured and the appearance performance of the diaphragm 400 can be prevented from being affected.

[0058] In some embodiments, referring to Figures 1 to 3 , the mist suction device 100 further includes a mounting member 190. The mounting member 190 is provided on the main body 110. The mounting member 190 has a chute 191 extending along the first direction X inside. The first baffle 150 and the second baffle 160 are respectively movably provided at both ends of the chute 191. An air inlet communicating with the suction slot 111 is provided in the middle of the mounting member 190.

[0059] Exemplarily, both the first baffle 150 and the second baffle 160 are stainless steel plates.

[0060] In some embodiments, referring to Figure 1 , the ventilation pipe 120 includes a pipe body 121, an air inlet end 122 and an air outlet end 123. The pipe body 121 penetrates through the main body 110. An air inlet groove 1211 is formed on the pipe body 121. The air inlet end 122 and the air outlet end 123 are respectively connected to both ends of the pipe body 121, and both the air inlet end 122 and the air outlet end 123 are exposed outside the main body 110. The air outlet end 123 is communicated with the suction port of the suction member 140.

[0061] When the dust and atomized slurry in the cavity flow into the pipe body 121 from the suction slot 111 along with the gas, since the air inlet end 122 is communicated with the outside air, the smooth flow of the gas in the pipe body 121 is ensured. The dust and atomized slurry in the pipe body 121 can flow towards the air outlet end 123 along with the gas.

[0062] In some embodiments, referring to Figure 1, the fog suction device 100 further includes a collection member 130. The collection member 130 is connected to the air outlet end 123 of the ventilation pipe 120. The interior of the collection member 130 is in communication with the interior of the ventilation pipe 120, and the interior of the collection member 130 is also in communication with the air extraction port of the air suction member 140.

[0063] Under the action of the air suction member 140, the dust and atomized slurry in the pipe body 121 can enter the collection member 130 through the air outlet end 123. The collection member 130 can collect the dust and atomized slurry to reduce the waste of the atomized slurry.

[0064] Exemplarily, the collection member 130 is a plastic-coated Teflon barrel.

[0065] In some embodiments, the height of the air inlet end 122 along the second direction Y is higher than that of the air outlet end 123 to prevent the atomized slurry and dust in the pipe body 121 from flowing into the air inlet end 122 due to gravity.

[0066] In some embodiments, please refer to Figure 1 , the fog suction device 100 further includes a filter member 170. The filter member 170 is disposed inside the connection between the collection member 130 and the ventilation pipe 120. The filter member 170 can prevent dust from entering the air suction member 140, thereby avoiding blockage of the air suction member 140.

[0067] Exemplarily, the filter member 170 is an electrospun filter cotton or a polyester fiber filter element.

[0068] In some embodiments, the fog suction device 100 further includes an air suction pipe 180. One end of the air suction pipe 180 is in communication with the air suction port of the air suction member 140, and the end of the air suction pipe 180 away from the air suction member 140 is in communication with the interior of the collection member 130.

[0069] Exemplarily, the air suction member 140 is a vortex air pump.

[0070] In some embodiments, the operator can adjust the power of the air suction member 140 to adapt to the separator 400 with different film widths.
