Description

Technical Field

[0001] This invention relates to the field of battery foil production technology, specifically to a device and method for removing dust from the surface of battery foil. Background Technology

[0002] Battery foil, also known as battery aluminum foil, is used as a current collector in lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode current collector, which has high requirements for the uniformity of color, flatness, and smoothness of the aluminum foil. However, during the production process, the surface of the freshly rolled aluminum foil will have a lot of dust and stains attached to it, and the surface of the aluminum foil needs to be cleaned in order to meet the requirements for use. Otherwise, it will affect the performance of the battery.

[0003] Chinese Patent CN110668234A discloses an aluminum foil winding device for cleaning the surface of aluminum foil. This device uses a cleaning tank to allow the surface of the aluminum foil to come into contact with water, thus achieving the purpose of cleaning the aluminum foil surface. Furthermore, a water spraying disc combined with cleaning guide rollers enhances the cleaning effect on the aluminum foil surface. Simultaneously, water-absorbing sponge layers are provided on the surfaces of the first, second, and third support rollers to absorb water adhering to the aluminum foil surface. However, the device lacks a mechanism to remove water from the water-absorbing sponge layers on the first, second, and third support rollers. This results in the first, second, and third support rollers becoming saturated with water over a long period and losing their ability to absorb water adhering to the aluminum foil surface. Additionally, the device only rinses one side of the aluminum foil with the water spraying disc, leaving the other side uncleaned, leading to poor aluminum foil cleaning results and affecting the quality of battery foil production.

[0004] Based on this, a dust removal device and method for battery foil surface is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a dust removal device and method for battery foil surfaces, so as to solve the problem in the prior art that it is inconvenient to remove water from the absorbent roller.

[0011] In one alternative embodiment: the cleaning mechanism includes a first cleaning roller and a second cleaning roller, both of which are rotatably disposed inside a cleaning tank. The first cleaning roller is positioned inside the cleaning tank corresponding to the upper end of the battery foil, and the second cleaning roller is positioned inside the cleaning tank corresponding to the lower end of the battery foil. A second driving gear and a second driven gear are respectively fixed on one end of the rotating shaft of the first and second cleaning rollers, and the second driving gear and the second driven gear mesh with each other. A third driven wheel on one end of the rotating shaft of the first cleaning roller is connected to a third driving wheel on one end of the rotating shaft of the second water-absorbing roller via a third belt.

[0012] In one alternative: a water pump is fixedly installed at the bottom of the dust collector corresponding to the position of the cleaning box. The output end of the water pump is connected to the inside of the cleaning box, the input end of the water pump is connected to the output end of the filter box on one side of the dust collector, the input end of the filter box is connected to the inside of the cleaning box, and the filter box is provided with several filter plates.

[0013] In one alternative: the extrusion mechanism includes extrusion rollers, two of which are respectively disposed inside the dust collection box at positions corresponding to the first and second water absorption rollers. A scraper is disposed inside the dust collection box corresponding to the positions of the extrusion rollers, and one side of the scraper is in close contact with the first and second water absorption rollers.

[0014] In one alternative embodiment: the drying mechanism includes two symmetrically arranged third air ducts, both of which are fixedly installed inside the dust collection box. The input end of the third air duct is connected to the output end of the second transmission pipe, and the input end of the second transmission pipe is connected to the output end of the heating box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this invention, the battery foil passes through the cleaning tank under the action of the guide roller through the cleaning mechanism. The first cleaning roller and the second cleaning roller inside the cleaning tank can clean both sides of the battery foil respectively. At the same time, by setting a water pump and a filter box, it is convenient to circulate and filter the cleaning liquid inside the cleaning tank, thereby increasing the cleaning effect on the surface of the battery foil.

[0019] 2. The present invention uses a squeezing mechanism. When the first and second water-absorbing rollers rotate, the squeezing rollers can easily squeeze the water-absorbing layer on the first and second water-absorbing rollers to squeeze out the cleaning liquid absorbed by the water-absorbing layer. At the same time, the scraper can easily scrape off the residual cleaning liquid and impurities on the water-absorbing layer, so as to keep the first and second water-absorbing rollers dry and clean. This solves the problem of inconvenience in removing water from the water-absorbing rollers and increases the practicality of the dust removal device on the surface of the battery foil.

[0020] 3. In this invention, the air is heated by a drying mechanism and then transported to the inside of a second transmission pipe. The output end of the second transmission pipe delivers the heated air to several scrapers and a third air duct. The third air duct keeps the surface of the battery foil dry, facilitating the winding process of the battery foil. The scrapers dry the first and second water-absorbing rollers, increasing their water absorption effect. Simultaneously, the fan delivers air to several first air ducts through the first transmission pipe. The first air ducts help reduce the amount of cleaning fluid adhering to the surface of the battery foil, and the water guide plate helps redirect the cleaning fluid adhering to the battery foil back into the cleaning tank, reducing the waste of cutting fluid and increasing the practicality of the battery foil surface dust removal device.

The inside of the dust removal box 11 is provided with a squeezing mechanism to facilitate the squeezing of the first water absorption roller and the second water absorption roller 21. The inside of the dust removal box 11 is provided with a drying mechanism to facilitate the drying of the battery foil at a position corresponding to the liquid collection box 24. The cleaning mechanism facilitates the cleaning of the surface of the battery foil inside the cleaning box 13, the squeezing mechanism facilitates the squeezing out of the water inside the second water absorption roller 21, and the drying mechanism facilitates keeping the battery foil dry.

[0029] The first drive assembly includes a motor 33, which is fixedly mounted on the upper end of the dust collection box 11. The first drive wheel on the output end of the motor 33 is connected to the first driven wheel on the rotating shaft of the first water absorption roller via a first belt. The first drive gear on the rotating shaft of the first water absorption roller meshes with the first driven wheel on the rotating shaft of the second water absorption roller 21. In use, when it is necessary to clean the cleaning liquid on the surface of the battery foil, the motor 33 is started. The first drive wheel on the output end of the motor 33 drives the first water absorption roller to rotate via the first belt. The first water absorption roller rotates by meshing with the first drive wheel and the first driven wheel, which in turn drives the second water absorption roller 21 to rotate. At the same time, the first water absorption roller and the second water absorption roller 21 rotate in opposite directions. The water absorption layer on the first water absorption roller and the second water absorption roller 21 is a sponge layer.

[0030] The second drive assembly includes a sleeve shaft fitted on the rotating shafts at both ends of the take-up roller 31. The sleeve shaft is fixedly connected to the take-up roller 31 by screws. A driven friction wheel 32 is fixedly mounted on the sleeve shaft at one end of the take-up roller 31. An active friction wheel is fitted on the driven friction wheel 32. The active friction wheel is fixedly mounted on a fixed shaft on one side of the dust collector 11. A second driven wheel is fixedly mounted on the fixed shaft. The second driven wheel is connected to a second active wheel on the rotating shaft at one end of the first water suction roller via a second belt. In use, when the first water suction roller rotates, it drives the fixed shaft to rotate via the second belt. The fixed shaft drives the active friction wheel to rotate. The active friction wheel and the driven friction wheel 32 cooperate to drive the take-up roller 31 to rotate. When the take-up roller 31 rotates, it can wind up the cleaned battery foil.

[0031] The cleaning mechanism includes a first cleaning roller 14 and a second cleaning roller, both of which are rotatably mounted inside a cleaning tank 13. The first cleaning roller 14 is positioned inside the cleaning tank 13 corresponding to the upper end of the battery foil, and the second cleaning roller is positioned inside the cleaning tank 13 corresponding to the lower end of the battery foil. A second driving gear and a second driven gear are respectively fixed on one end of the rotating shaft of the first cleaning roller 14 and the second cleaning roller, and the second driving gear and the second driven gear mesh with each other. A third driven wheel on one end of the rotating shaft of the first cleaning roller 14 is connected to a third driving wheel on one end of the rotating shaft of the second water absorption roller 21 via a third belt. In use, when the second water absorption roller 21 rotates, it drives the third driven wheel to rotate via the third belt. When the third driven wheel rotates, it drives the first cleaning roller 14 to rotate. When the first cleaning roller 14 rotates, it drives the second cleaning roller to rotate via the meshing of the second driving gear and the second driven gear. The rotation of the first cleaning roller 14 and the second cleaning roller can clean the surface of the battery foil.

[0032] A water pump 15 is fixedly installed at the bottom of the dust collector 11, corresponding to the position of the cleaning box 13. The output end of the water pump 15 is connected to the inside of the cleaning box 13, and the input end of the water pump 15 is connected to the output end of the filter box 16 on one side of the dust collector 11. The input end of the filter box 16 is connected to the inside of the cleaning box 13. The filter box 16 is equipped with several filter plates. In use, the cleaning liquid is drawn from the inside of the filter box 16 through the input end of the water pump 15. The cleaning liquid in the cleaning box 13 flows into the filter box 16 and then passes through several filter plates to filter the cleaning liquid for reuse. The water pump 15 then delivers the filtered cleaning liquid back into the cleaning box 13.

[0033] The extrusion mechanism includes extrusion rollers 22, two of which are respectively disposed inside the dust collection box 11 at positions corresponding to the first and second water absorption rollers 21. A scraper 23 is disposed inside the dust collection box 11 at a position corresponding to the extrusion rollers 22. One side of the scraper 23 is in close contact with the first and second water absorption rollers 21. In use, when the first and second water absorption rollers 21 rotate, they can absorb the residual cleaning liquid on the surface of the battery foil. Then, when the water absorption area rotates to the position corresponding to the extrusion rollers 22, the extrusion rollers 22 squeeze the water absorption area, squeezing out the cleaning liquid. The cleaning liquid on the first water absorption roller falls onto the upper end of the scraper 23 and then falls into the collection box 24. At the same time, the scraper 23 can scrape off the residual cleaning liquid and impurities on the first and second water absorption rollers 21.

[0034] The drying mechanism includes two symmetrically arranged third air ducts 29, both of which are fixed inside the dust collection box 11. The input end of the third air duct 29 is connected to the output end of the second transmission pipe 27, and the input end of the second transmission pipe 27 is connected to the output end of the heating box 28. The heating box 28 is fixed at the upper end of the dust collection box 11, and its input end is connected to the output end of the fan 20. In use, when the fan 20 is working, it delivers air to the heating box 28, which heats the air. The heating box 28 then delivers the heated air to the second transmission pipe 27, and the output end of the second transmission pipe 27 delivers the heated air to the third air duct 29. The third air duct 29 discharges air through several air outlets on one side, which can dry the surface of the battery foil. At the same time, the heated air can dry the surfaces of the first and second water absorption rollers 21.

[0035] The dust removal box 11 is equipped with a second air duct 26 corresponding to the positions of the first and second water suction rollers 21. The second air duct 26 has several air outlets on one side. The input end of the second air duct 26 is connected to the output end of the second transmission pipe 27. In use, when the heating box 28 heats the air delivered by the fan 20, it is delivered to the inside of the second transmission pipe 27. The air inside the second transmission pipe 27 is delivered to the inside of several second air ducts 26 and third air ducts 29. The second air ducts 26 can heat the second water suction roller 21, making the surface of the second water suction roller 21 dry and increasing the water absorption effect of the second water suction roller 21.

[0036] The dust removal box 11 is equipped with several first leveling rollers 12 and second leveling rollers 30 at its two ends, which facilitates the leveling of the battery foil during use.

[0037] The above embodiment discloses a dust removal device for battery foil surfaces. When cleaning and winding the battery foil, several guide rods inside the dust collection box 11 guide the battery foil, fixing one end of the foil to the winding roller 31. Then, the motor 33 is started. The first drive wheel at the output end of the motor 33 drives the first water-absorbing roller to rotate via a first belt. The first water-absorbing roller, through the meshing of the first drive wheel and the first driven wheel, drives the second water-absorbing roller 21 to rotate. Simultaneously, the first and second water-absorbing rollers 21 rotate in opposite directions. When the second water-absorbing roller 21 rotates, it drives the third driven wheel to rotate via a third belt. When the three driven wheels rotate, they drive the first cleaning roller 14 to rotate. When the first cleaning roller 14 rotates, it drives the second cleaning roller to rotate through the meshing of the second driving gear and the second driven gear. The rotation of the first cleaning roller 14 and the second cleaning roller can clean the surface of the battery foil. Then the battery foil moves to the top of the connecting pipe 25. A water guide plate 17 is provided above the connecting pipe 25 to facilitate the return of the cleaning liquid to the cleaning tank 13 after the battery foil falls. Then the fan 20 and the heating box 28 are started. When the fan 20 is working, it delivers air to the first transmission pipe 19 and the heating box 28. The first transmission pipe 19 delivers air to the first air duct 18. The first air duct 18 discharges air through several air outlets, blowing off the cleaning liquid on the surface of the battery foil to reduce the amount of cleaning liquid carried on the battery foil. Then, the first and second absorbent rollers 21 absorb the cleaning liquid on the battery foil. When the absorbent area rotates to the position corresponding to the squeeze roller 22, the squeeze roller 22 squeezes the absorbent area, expelling the cleaning liquid. The cleaning liquid on the first absorbent roller falls onto the upper end of the scraper 23 and then into the collection tank 24. Simultaneously, the scraper 23 scrapes off any remaining cleaning liquid and impurities on the first and second absorbent rollers 21. The heating box 28... The air is heated, and then the heating box 28 delivers the heated air to the inside of the second transmission pipe 27. The output end of the second transmission pipe 27 delivers the heated air to the inside of the third air duct 29. The third air duct 29 discharges air through several air outlets on one side, which can dry the surface of the battery foil. At the same time, the heated air can dry the surface of the first water-absorbing roller and the second water-absorbing roller 21. Meanwhile, the air inside the second transmission pipe 27 is delivered to several second air ducts 26, which can heat the second water-absorbing roller 21, dry the surface of the second water-absorbing roller 21, and increase the water absorption effect of the second water-absorbing roller 21.
