Description

Technical Field

[0001] This utility model relates to the field of aluminum foil processing technology, specifically to a surface cleaning device for aluminum foil used in power batteries of new energy vehicles. Background Technology

[0002] Against the backdrop of a global push for green travel, the new energy vehicle industry has flourished. As a core component of new energy vehicles, the performance of power batteries directly affects the vehicle's range, charging and discharging efficiency, and safety and reliability. Aluminum foil, with its excellent conductivity, good flexibility, and light weight, is widely used in key components such as electrodes and current collectors in power battery manufacturing. However, during the processing of aluminum foil, liquid substances such as alcohol may remain on its surface. Therefore, to avoid affecting subsequent vacuum packaging, it is necessary to clean the surface of the aluminum foil of these liquid substances.

[0003] For example, patent CN214683053U discloses an aluminum foil surface cleaning device for lithium batteries, which includes a conveyor belt, a motor, a heating wire, a pulley mechanism, a cleaning box, fan blades, a cleaning block, and a cleaning device. This cleaning device achieves the effect of cleaning residual liquid substances such as alcohol on the surface of aluminum foil by using hot air generated by the fan blades in conjunction with the heating wire, and can simultaneously clean the substances adhering to the conveyor belt to facilitate the subsequent vacuum packaging of aluminum foil.

[0004] However, the cleaning device provided by the aforementioned patent, when in use, relies on the cleaning blocks to remove liquid substances such as alcohol adhering to the aluminum foil on the conveyor belt surface. After repeated use, the sponge-material cleaning blocks absorb a large amount of alcohol and impurities, gradually saturating their adsorption and cleaning capacity, making it difficult to effectively remove stains from the conveyor belt surface. Simultaneously, the cleaning blocks are constantly subjected to friction during prolonged contact with the conveyor belt surface, especially during the cleaning process, where they may rub against impurities on the conveyor belt. Over time, the surface of the cleaning blocks gradually wears down, altering their shape and affecting their fit with the conveyor belt, thus reducing cleaning effectiveness. Therefore, it is essential to design a new aluminum foil surface cleaning device to address these issues. Utility Model Content

[0054] Example 1

[0055] like Figures 1-4As shown in the figure, this embodiment 1 designs a surface cleaning device for aluminum foil of power battery of new energy vehicle, which includes the following specific structural configuration:

[0056] The support frame 1 has a first direction and a second direction that are perpendicular to each other, and a mounting frame 11 is provided on its top. The mounting frame 11 is provided with a slot 12 extending in the second direction, and a limiting plate 13 extending in the second direction is also provided in the mounting frame 11.

[0057] The conveying assembly 2 is fixedly mounted on the mounting frame 11 and is used to convey aluminum foil in a first direction. Specifically, the conveying assembly 2 includes a conveying frame 21, two conveying rollers 22, a conveyor belt 23, and a first drive motor 24. The conveying frame 21 is fixedly mounted on the mounting frame 11 in the first direction. The two conveying rollers 22 are rotatably mounted at both ends of the conveying frame 21 in the first direction. The conveyor belt 23 is connected to the two conveying rollers 22 (the two conveying rollers 22 are driven by the conveyor belt 23) for conveying aluminum foil in the first direction. The conveyor belt 23 is also evenly distributed with a number of ventilation holes 231. The first drive motor 24 is mounted on the conveying frame 21 and is used to drive the conveying rollers 22 to rotate, thereby driving the conveyor belt 23 to transport the aluminum foil placed on it.

[0058] Cleaning component 3, mounted on conveying component 2, is used to surface-blow aluminum foil conveyed in conveying component 2. Specifically, cleaning component 3 includes a cleaning box 31, two sets of second drive motors 32, two sets of fan blades 33, heating wire 34, adsorption frame 35, and several adsorption tubes 36. The cleaning box 31 is a hollow structure, mounted on conveying frame 21 and located above conveyor belt 23. Several air outlets 311 are also provided at the bottom of the cleaning box 31. The second drive motors 32 are located at the top of the cleaning box 31, with their output ends extending into the interior of the cleaning box 31. The fan blades 33 are located at the output ends of the second drive motors 32 and inside the cleaning box 31. The air vent 311 is located directly below the fan blade 33. The heating wire 34 is located inside the cleaning box 31. When the heating wire 34 is heated, the fan blade 33 can be activated to blow hot air onto the aluminum foil surface on the conveyor belt 23 below, so as to quickly remove residual alcohol and other liquids from the aluminum foil surface. The adsorption frame 35 is connected to the conveyor frame 21 on both sides in the second direction and is located between the conveyor belts 23. At the same time, the adsorption frame 35 does not contact the conveyor belt 23. The adsorption frame 35 is provided with several adsorption holes 351. The adsorption tube 36 is located outside the cleaning box 31. One end of the tube extends into the interior of the cleaning box 31 and is located above the fan blade 33. The other end is connected to the adsorption hole 351.

[0059] The wiping assembly 4 is slidably inserted into the mounting frame 11 along the second direction via the slot 12 to form a drawer-type structure. The wiping assembly 4 is limited in the slot 12 by a limiting plate 13 extending in the second direction. The wiping assembly 4 is located below the conveyor belt 23 and is used to wipe the conveying assembly 2 located above it. Specifically, the wiping assembly 4 includes a mounting plate 41, several wiping units 42, a limiting rod 43, a limiting unit 44, a third drive motor 45, a handle 46, and a pull rod 47. The mounting plate 41 is slidably inserted into the slot 12 along the second direction via the slot 12. In groove 12, the mounting plate 41 is also provided with four sets of adjustment grooves 411 extending in the second direction. A sliding plate 412 perpendicular to the mounting plate 41 is slidably disposed in the adjustment groove 411, and one end of the sliding plate 412 extends out of the adjustment groove 411. A first spring 413 is connected between the sliding plate 412 and the adjustment groove 411. A plurality of wiping units 42 are rotatably disposed on the mounting plate 41 in the second direction and are mutually driven among the plurality of wiping units 42 for wiping the conveyor belt 23 located above it. The limiting rod 43 is disposed above the mounting plate 41 in the second direction and is connected to the sliding plate. One end of 412 is connected to a limiting rod 43, which also has a mounting groove 431 extending in the second direction. Several limiting units 44 are provided in the mounting groove 431. The limiting units 44 form rolling contact with the wiping units 42 to limit the wiping units 42 on both sides in the first direction. That is, the number of limiting units 44 is twice the number of wiping units 42. The third drive motor 45 is mounted on the mounting plate 41 and drives one of the wiping units 42 to rotate. The remaining wiping units 42 rotate together through mutual transmission between themselves. The handle 46 is mounted on the mounting plate 41 to facilitate pushing the entire wiping assembly 2 into or out of the slide groove 12. The pull rod 47 is mounted on the limiting rod 43 to facilitate pulling the limiting rod 43 in the second direction to prevent the limiting unit 44 from contacting the wiping unit 42, thereby releasing the restriction of the limiting unit 44 on the wiping unit 42 in the first direction. This allows the wiping unit 42 that is worn out to be replaced. After replacement, the limiting rod 43 is reset under the action of the first spring 413, and the limiting unit 44 contacts the wiping unit 42 again to limit it.

[0060] Specifically, the aforementioned wiping unit 42 includes a gear 421, a rotating shaft 422, an annular mounting member 423, a magnetic ring 424, a fixing member 425, and a sponge block 427. The gear 421 is rotatably mounted on the mounting plate 41 via the rotating shaft 422. The gears 421 in the plurality of wiping units 42 mesh with each other to realize the transmission between the wiping units 42. The annular mounting member 423 is mounted on the rotating shaft 422 and also contains a magnetic ring 424. The fixing member 425 is mounted in the annular mounting member 423 and is attracted and fixed by the magnetic ring 424. An annular groove 426 adapted to the limiting unit 44 is also provided in the circumference of the fixing member 425. The limiting unit 44 and the annular groove 426 form a rolling contact. The sponge block 427 is detachably mounted in the fixing member 425 and is used to wipe the conveyor belt 23 located above it.

[0061] The aforementioned limiting unit 44 includes a guide rod 441, a limiting ball head 442, and a second spring 443. The guide rod 441 is movably inserted into the limiting rod 43 (mounting groove 431) and one end extends toward the wiping unit 42 (specifically toward the annular groove 426 on the fixing member 425). The limiting ball head 442 is configured as a hemispherical structure and is rotatably disposed at the end of the guide rod 441. The limiting ball head 442 can engage with the annular groove 426 and form a rolling contact, thereby creating a limiting effect on the fixing member 425 on both sides in the first direction. The second spring 443 is sleeved on the guide rod 441. One end of the second spring 443 abuts against the bottom of the mounting groove 431, and the other end contacts the limiting ball head 442. Under the elastic force of the second spring 443, the limiting ball head 442 can engage in the annular groove 426, and since the limiting ball head 442 is rotatably disposed, it can form a rolling contact with the annular groove 426.

[0062] The working process of the surface cleaning device for aluminum foil of new energy vehicle power batteries designed in Embodiment 1 above:

[0063] When the cleaning component 3 is working, the two sets of second drive motors 32 start up, driving the fan blades 33 to rotate at high speed in the cleaning box 31 to generate wind; at the same time, the heating wires 34 in the cleaning box 31 are energized and heat up, turning the air blown out by the fan blades 33 into hot air. The hot air is blown onto the conveyor belt 23 through the air outlet 311 at the bottom of the cleaning box 31. The purpose is to use the hot air to dry the residual liquid substances such as alcohol on the surface of the aluminum foil on the conveyor belt 23, or to remove some impurities on the surface that are easily affected by heat, so as to meet the requirements of subsequent production processes for the cleanliness and dryness of the aluminum foil surface.

[0064] Meanwhile, multiple sets of adsorption tubes 36 are connected and installed on the cleaning box 31. One end of the adsorption tube 36 extends into the interior of the cleaning box 31 and is located above the fan blade 33. An adsorption frame 35 that does not contact the conveyor belt 23 is set between the conveyor belts 23. The adsorption frame 35 is provided with an adsorption hole 351. The other end of the adsorption tube 36 is connected to the adsorption hole 351. When the fan blade 33 rotates with the second drive motor 32, a negative pressure area is formed above the fan blade 33 due to the rapid air flow, thereby generating suction. This suction is conducted to the adsorption frame 35 through the adsorption tube 36, and then adsorbs the aluminum foil on the conveyor belt 23 above the adsorption frame 35. This can effectively resist the hot air blow, prevent the aluminum foil from shifting position, and ensure the stability of the aluminum foil during the cleaning process.

[0065] To prevent liquid substances such as alcohol on the aluminum foil from adhering to the conveyor belt 23 and affecting the subsequent aluminum foil conveying, a wiping component 4 is designed. When in use, the third drive motor 45 is started to drive the connected rotating shaft 422 and gear 421 to rotate. Since the gears 421 in the multiple wiping units 42 mesh with each other, they will drive all the wiping units 42 to rotate together synchronously. The rotating sponge block 427 contacts the bottom of the conveyor belt 23 to wipe it and remove the residual liquid substances such as alcohol on the aluminum foil, thereby keeping the conveyor belt 23 clean.

[0066] When the reusable sponge block 427 needs to be replaced, pull the handle 46 on the mounting plate 41 to pull the mounting plate 41 out from the side of the slide groove 12, and then pull the pull rod 47 on the two sets of limit rods 43 to make the limit rods 43 move in the adjustment groove 411 along the second direction. Then the two sets of oppositely arranged limiting ball heads 442 overcome the force of the second spring 443 and disengage from the annular groove 426, thereby releasing the restriction on the first direction and vertical direction of the fixing member 425 (sponge block 427). At this time, the sponge block 247 can be easily taken out for replacement. After the replacement is completed, the limiting rod 43 is reset under the elastic force of the first spring 413, and the limiting ball head 442 contacts and engages with the annular groove 426 again to limit the fixing member 425.

[0067] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
