Description

Technical Field

[0001] This disclosure pertains to the field of copper foil technology, specifically relating to a cleaning device and a foil production system. Background Technology

[0002] In the field of copper foil technology, foreign matter such as crystals can easily be generated on the O-rings and guide wheels of the foil production machine. These foreign matter may cause the O-rings to not seal properly during the copper foil production process and may cause the copper foil to tear at the edges. If the crystals fall off onto the copper foil, they may also cause scratches, bumps, or even pinholes.

[0003] There is no existing technical solution that can automatically clean O-rings. Usually, the O-rings and guide wheels are cleaned manually by spraying water on them periodically during the up and down rolling. This is not only time-consuming and labor-intensive, but also carries the risk of forgetting to clean them or not cleaning them thoroughly. Utility Model Content

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0035] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0037] like Figure 1 and Figure 2As shown, this disclosure provides a cleaning device, which may include at least a cleaning box 100, and the cleaning box 100 may include a box body 1 and a cleaning structure 17.

[0038] Specifically, the interior of the box 1 is hollow, forming a receiving space. The side wall of the box 1 has a through-hole structure, which is configured to allow the part to be cleaned 6 to enter and exit the receiving space, and is configured to rub against the part to be cleaned 6 when it enters and exits the receiving space. The cleaning structure 17 is located in the receiving space and is configured to clean the part to be cleaned 6 located in the receiving space.

[0039] This disclosure utilizes a housing 1 to generate friction between the housing 1 and the part 6 to be cleaned, thereby scraping off impurities. A cleaning structure 17 is provided within the housing 1 to remove these impurities. In other words, during the movement of the part 6, the cleaning box 100 automatically scrapes off impurities from the part 6 using the housing 1, and the cleaning structure 17 within the housing space removes the impurities. This achieves automatic cleaning of the part 6, improving upon the problem of forgetting parts during manual cleaning, thus maintaining the cleanliness of the part 6 and reducing labor costs.

[0040] It should be noted that the component 6 to be cleaned in this disclosure can be an O-ring in a foil-forming machine. During operation, the O-ring moves under the action of guide wheels and enters and exits the receiving space through a through-hole structure. Thus, the O-ring can be automatically cleaned by the cleaning box 100 during operation to remove crystalline foreign matter from the O-ring. This improves the problem of incomplete O-ring sealing and copper foil tearing caused by these foreign objects during copper foil production. Simultaneously, it reduces the likelihood of crystalline foreign matter falling onto the copper foil and causing scratches, dents, or even pinholes. Furthermore, compared to manual cleaning of the O-ring, using the cleaning box 100 allows for more comprehensive cleaning, improving the problem of inadequate O-ring cleaning.

[0041] However, it is not limited to this. The part to be cleaned 6 in this disclosure can also be other structures besides O-rings, depending on the specific circumstances.

[0042] In some embodiments, the through-hole structure may include a through-hole that penetrates the side wall of the housing 1. The part to be cleaned 6 can enter and exit the receiving space through the through-hole. When passing through the through-hole, the part to be cleaned 6 can contact the side wall of the through-hole and rub against it, thereby scraping off the impurities on the part to be cleaned 6 and cleaning the part to be cleaned 6.

[0043] In some embodiments, the through-hole structure may include a through-hole penetrating the sidewall of the housing 1 and a flexible portion 12 disposed at the through-hole, the flexible portion 12 being configured to rub against the part 6 to be cleaned when it enters or exits the receiving space through the through-hole.

[0044] Specifically, the flexible portion 12 may include a plurality of flexible scrapers 11, which are arranged circumferentially at the through hole. The first ends of the flexible scrapers 11 are connected to the housing 1, and the second ends of the flexible scrapers 11 extend in a direction close to the center of the through hole. The second ends of the flexible scrapers 11 are configured to rub against the part 6 to be cleaned as it moves through the through hole into and out of the receiving space. By providing a plurality of flexible scrapers 11 in the flexible portion 12, the multiple flexible scrapers 11 can make corresponding adjustments to avoid the movement of the part 6 when it moves in and out of the receiving space, thereby reducing the difficulty for the part 6 to enter and exit the receiving space.

[0045] For example, such as Figure 1 and Figure 3 As shown, the second ends of a plurality of flexible scrapers 11 in the flexible part 12 can collectively form a through hole 18 for the part to be cleaned 6 to pass through. The through hole 18 is configured to allow the part to be cleaned 6 to pass through, and when the part to be cleaned 6 passes through the through hole 18 to enter or exit the receiving space, the second end of the flexible scraper 11 can rub against the part to be cleaned 6 to scrape off the impurities on the part to be cleaned.

[0046] Furthermore, in this embodiment, the shape of the through hole 18 formed by the plurality of flexible scrapers 11 can be adapted to the shape of the part 6 to be cleaned entering the cleaning box 100, so as to facilitate all-round cleaning of the part 6 to be cleaned.

[0047] For example, when the cross-sectional shape of the part 6 to be cleaned entering the cleaning box 100 is circular, the shape of the through hole 18 formed by the multiple flexible scrapers 11 can also be circular, and the diameter of the through hole 18 can be equal to or smaller than the diameter of the cross-section of the part 6 to be cleaned, so that the flexible scrapers 11 can better and more thoroughly remove impurities from the part 6 to be cleaned.

[0048] However, this is not the only embodiment. In some embodiments, the multiple flexible scrapers 11 in the flexible portion 12 may also completely cover the through hole.

[0049] For example, such as Figure 2 and Figure 4As shown, the second ends of the plurality of flexible scrapers 11 can be pointed, and the second ends of the plurality of flexible scrapers 11 extend to the same point and contact each other. During the process of the part to be cleaned 6 passing through the through hole, the flexible scrapers 11 can deform to facilitate the passage of the part to be cleaned 6 and to rub against the part to be cleaned 6. When the part to be cleaned 6 does not pass through the through hole, the flexible scrapers 11 can restore their deformation and completely cover the through hole, so as to improve the problem of external dust entering the cleaning box 100 and causing contamination to the cleaning box 100.

[0050] In this embodiment, the flexible scraper 11 can be made of ABS (acrylonitrile-butadiene-styrene) to reduce damage to the part to be cleaned 6 while cleaning it. However, it is not limited to this, and other materials with good flexibility and impact resistance can be included in this embodiment.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the through-hole structure may include an inlet 13 and an outlet 14, both of which penetrate the side wall of the cleaning box 100. The part to be cleaned 6 can enter the receiving space through the inlet 13 and leave through the outlet 14.

[0052] For example, the inlet 13 and the outlet 14 can be located on opposite sides of the cleaning box 100 to reduce the resistance encountered by the part to be cleaned 6 when entering and exiting the cleaning box 100, thereby reducing the driving force for driving the part to be cleaned 6 to enter and exit the cleaning box 100, and thus reducing the energy consumption of the part to be cleaned 6 when entering and exiting the cleaning box 100.

[0053] However, it is not limited to this. The through-hole structure in this disclosure may also include a through hole, through which the cleaning component 6 can enter the receiving space and then leave.

[0054] In some embodiments, a plurality of cleaning structures 17 may be provided inside the cleaning box 100. The plurality of cleaning structures 17 may be evenly spaced on the inner wall of the cleaning box 100 to achieve multi-directional cleaning of the part 6 to be cleaned.

[0055] For example, such as Figure 1 and Figure 2 As shown, in this embodiment of the present disclosure, a cleaning structure 17 can be provided on at least one of the top wall, side wall, and bottom wall of the cleaning box 100 to clean multiple locations of the component 6 to be cleaned. Furthermore, as... Figure 5 As shown, multiple cleaning structures 17 can also be provided on one side wall of the box body 1.

[0056] In this embodiment, the cleaning structure 17 can be a cleaning tube installed on the cleaning box 100, but it is not limited to this. The cleaning structure 17 can also be a nozzle, liquid inlet or other structure provided on the inner wall of the cleaning box 100. The cleaning agent in the cleaning structure 17 can be used to clean away the impurities attached to the part 6 to be cleaned.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the bottom wall of the cleaning box 100 may be provided with a liquid outlet 15, which is configured to discharge liquid from the containing space into the cleaning box 100. The inner side of the bottom wall of the cleaning box 100 slopes downward in the direction near the liquid outlet 15, so that solid impurities, waste liquid, etc. inside the containing space can flow out of the cleaning box 100 through the liquid outlet 15 under the action of gravity, thereby keeping the inside of the cleaning box 100 clean.

[0058] For example, the angle between the inner side of the bottom wall of the cleaning box 100 and the horizontal plane can be in the range of 20°-45°.

[0059] For example, the angle between the inner side of the bottom wall of the cleaning box 100 and the horizontal plane can be 20°, 25°, 30°, 35°, 40°, 45°, etc., depending on the actual situation.

[0060] Furthermore, the cleaning box 100 may also include a connecting structure 16 arranged around the liquid outlet 15. The connecting structure 16 is located outside the containing space and connected to the bottom wall of the cleaning box 100. The bottom end of the connecting structure 16 extends away from the containing space. The connecting structure 16 is configured to connect to an external pipeline to guide solid impurities, waste liquid, etc. in the containing space to an external impurity recovery device.

[0061] For example, such as Figure 1 and Figure 2 As shown, in this embodiment, the sidewalls and top wall of the cleaning box 100 can together form a rectangular receiving space. A through-hole structure can be provided on each of the two opposite sidewalls, and a cleaning structure 17 can be provided on the other two sidewalls and the top wall. The liquid outlet 15 can be located in the middle of the bottom wall of the cleaning box 100, and the bottom wall of the cleaning box 100 forms an inverted truncated pyramid. The connecting structure 16 can be designed according to the structure of the external pipeline; for example, the connecting structure 16 can be in the shape of a quadrangular prism, cylinder, etc.

[0062] This disclosure, by setting up a cleaning box 100, can achieve self-controlled and all-round cleaning of O-rings using a through-hole structure and a cleaning structure 17, which improves the problems that occur when cleaning is done manually on a regular basis: easy to forget to clean regularly, difficulty in controlling the flow of cleaning fluid, and easy to cause incomplete cleaning, thereby improving cleaning efficiency and reducing cleaning costs.

[0063] like Figures 6 to 8 As shown, in some embodiments, the cleaning device may further include a liquid collection box 200, on which a liquid collection trough and a flow port 21 are formed. The opening of the liquid collection trough faces upward and is configured to receive liquid on the worktable. The flow port 21 communicates with the liquid collection trough and is configured to drain liquid from the liquid collection trough.

[0064] It should be noted that when there are multiple parts 6 to be cleaned, multiple flow ports 21 can be formed on the liquid collection box 200. At this time, a drip tube 3 can be provided on at least some of the flow ports 21. The drip tube 3 corresponds one-to-one with the parts 6 to be cleaned and is configured to clean the part of the parts 6 to be cleaned located outside the cleaning box 100.

[0065] Specifically, the inlet 13 end of the drip tube 3 can be connected to the liquid collection box 200, and the outlet 14 end of the drip tube 3 can be set above the corresponding part 6 to be cleaned. After the liquid collection box 200 collects the liquid, the liquid in the liquid collection box 200 can be introduced into the drip tube 3, and the liquid in the liquid collection box 200 can be used to clean the part of the part 6 to be cleaned that is outside the cleaning box 100.

[0066] This embodiment of the present disclosure provides a drip tube 3 on a portion of the flow port 21 on the liquid collection box 200, which allows the liquid collected from the workbench to be cleaned directly, thus eliminating the need to obtain external pure water to clean the workbench 6 and reducing cleaning costs.

[0067] Furthermore, the cleaning of the part to be cleaned 6 by the drip tube 3 depends on the amount of liquid accumulated in the liquid collection box 200. When there is no liquid in the liquid collection box 200, the drip tube 3 will automatically stop, thus eliminating the need for manual operation by the operator and reducing labor costs. In this embodiment of the present disclosure, the drip tube 3 can be used to initially clean the part to be cleaned 6 located outside the cleaning box 100. When the part to be cleaned 6 enters or exits the receiving space, the through holes and cleaning structure 17 on the cleaning box 100 can be used to perform deep cleaning of the part to be cleaned 6, thereby improving the cleanliness of the part to be cleaned 6.

[0068] It should be noted that the working machine in this disclosure can be a foil-making machine, the part to be cleaned 6 in this disclosure can be an O-ring, and the cleaning box 100 and the drip tube 3 on the liquid collection box 200 in the cleaning device can be used together to clean the O-ring in the foil-making machine.

[0069] Furthermore, the part 6 to be cleaned in this disclosure can also be an O-ring and a guide wheel. The drip irrigation tube 3 can clean the guide wheel and the O-ring located on it.

[0070] However, it is not limited to this. The cleaning device in this disclosure can also be used to clean other structures besides the foil-making machine, depending on the actual situation.

[0071] The liquid collection box 200 may include an inlet side and an outlet side. The inlet side is located on the side of the liquid collection box 200 closer to the worktable to receive liquid on the worktable, and the outlet side is located on the side of the liquid collection box 200 away from the worktable.

[0072] In some embodiments, the liquid collection box 200 may include a rear baffle 2 disposed on its liquid outlet side, the rear baffle 2 being configured to form part of the sidewall of the liquid collection tank for containing the liquid flowing onto the liquid collection box 200 within the liquid collection tank.

[0073] The flow port 21 can be set at the bottom of the rear baffle 2. After the liquid enters the liquid accumulation tank from the inlet side, it can gradually flow to the outlet side and accumulate on the outlet side.

[0074] In this embodiment, by setting the flow port 21 on the rear baffle 2, the liquid accumulated in the liquid collection tank near the liquid outlet side can provide a stable liquid flow to the dripping tube 3, thereby facilitating the control of the flow rate of the dripping tube 3 and improving the problem of poor cleaning effect on the part to be cleaned 6 due to the unstable flow rate at the outlet 14 of the dripping tube 3.

[0075] However, it is not limited to this. In addition to setting the flow port 21 on the rear baffle 2, the flow port 21 can also be set on the bottom wall of the liquid accumulation tank. The specific setting can be made according to the actual situation.

[0076] It should be noted that compared with the volume of liquid collected from the workbench by the liquid collection box 200, the volume of liquid flowing out of the drip tube 3 for cleaning the parts 6 to be cleaned is smaller. If the liquid in the collection tank is discharged only through the drip tube 3, after long-term operation, the liquid may overflow the liquid collection box 200 and cause pollution to the external environment.

[0077] To solve the above problems, such as Figure 8 As shown, in this embodiment of the present disclosure, the flow port 21 on the liquid collection box 200 that is not connected to the drip irrigation tube 3 can be connected to an external pipeline such as the waste liquid tube 4, so that the excess liquid not used for cleaning the part to be cleaned 6 can be discharged from the liquid collection tank to an external waste liquid collection device through the external pipeline.

[0078] However, this is not the only option. In this embodiment, at least a portion of the flow port 21 on the liquid collection box 200 that is not connected to the drip irrigation tube 3 can be connected to the cleaning structure 17 on the cleaning box 100. This allows the liquid in the liquid collection box 200 to be used to clean the part 6 to be cleaned, thereby reducing or avoiding the need for the cleaning device to obtain pure water from the outside to clean the part 6, and thus reducing cleaning costs.

[0079] In some embodiments, a control valve may be provided on the flow port 21 connected to the drip tube 3. The control valve is configured to regulate the liquid flow into the drip tube 3, thereby improving the problem of liquid waste caused by excessive liquid flow in the drip tube 3, and also improving the problem of inadequate cleaning of the part to be cleaned 6 caused by insufficient liquid flow in the drip tube 3, thereby improving the cleaning efficiency of the part to be cleaned 6.

[0080] In addition, control valves may be provided on all flow ports 21 in this embodiment.

[0081] The flow port 21 connected to external pipelines such as the waste liquid pipe 4 is defined as the second through hole, and the other flow ports 21 (e.g., the flow port 21 connected to the drip pipe 3, the flow port 21 connected to the cleaning structure 17) are defined as the first through hole. By controlling the opening of the control valves on the first and second through holes respectively, the liquid flow in the drip pipe 3 used to clean the parts 6 to be cleaned and the liquid flow discharged to the waste liquid collection device through the second through hole can be controlled.

[0082] For example, when the liquid volume in the collection tank is low, the opening of the control valve on the second through-hole can be reduced, and the opening of the control valve on the first through-hole can be increased. This can improve the problem of inadequate cleaning of the part to be cleaned 6 due to insufficient liquid flow in the drip tube 3. When the liquid volume in the collection tank is high, the opening of the control valve on the second through-hole can be increased so that excess liquid in the collection tank can be quickly discharged into the external waste liquid collection device through the second through-hole, reducing the problem of liquid overflow from the collection tank and causing environmental pollution.

[0083] For example, when the liquid collection box 200 is installed above the anode tank in the foil production system and is used to collect the foil washing water from the foil production machine, the excess liquid in the liquid collection tank can be discharged to the external waste liquid collection device by using external pipelines such as the second through hole and the waste liquid pipe 4. This can improve the problem of the foil washing liquid flowing into the anode tank and causing the anode tank to be contaminated.

[0084] In some embodiments, the inner wall of the liquid collection box 200 in the corner area on the liquid outlet side may be sloped 19, and the sloped 19 slopes downward in the direction close to the flow port 21.

[0085] For example, such as Figure 9 As shown, the liquid collection box 200 in this embodiment can be a hollow rectangular box 1, and the accommodating space formed inside the liquid collection box 200 can also be approximately rectangular. The two opposite ends of the liquid outlet side of the liquid collection box 200 form a corner area, and a plurality of flow ports 21 are formed between the two corner areas.

[0086] In this embodiment of the present disclosure, by making the inner wall of the corner area of ​​the liquid collection box 200 on the liquid outlet side sloped 19, the liquid in the liquid collection box 200 can be concentrated and flow towards the flow port 21. While facilitating the discharge of liquid from the liquid collection box 200, the sloped 19 can also reduce the residue of liquid in the corner area of ​​the liquid collection box 200.

[0087] When some of the flow ports 21 on the liquid collection box 200 are connected to the drip irrigation tube 3, and some of the flow ports 21 are connected to external pipelines such as the waste liquid tube 4, the second through hole connected to the waste liquid tube 4 or other external pipelines can be set on the side of the first through hole connected to the drip irrigation tube 3 near the center of the liquid collection box 200. In this way, a large amount of liquid in the liquid collection box 200 can be collected in the second through hole, so that excess liquid in the liquid collection tank can be discharged from the liquid collection box 200 through the second through hole.

[0088] For example, when two parts 6 to be cleaned are provided on the workbench, three flow ports 21 arranged in a horizontal direction can be provided on the liquid collection box 200. These ports can include two first through holes arranged at intervals and a second through hole provided between the two first through holes. This allows the liquid in the liquid collection tank to accumulate in the second through hole and most of the liquid in the liquid collection tank to be discharged out of the liquid collection tank through the second through hole.

[0089] In some embodiments, the inner bottom wall of the liquid collection box 200 can be inclined downward in the direction close to the liquid outlet side, so that the liquid on the inlet side can flow to the outlet side under the action of gravity and be discharged from the liquid collection box 200 through the flow port 21, thereby reducing the liquid residue in the liquid collection box 200 and facilitating the cleaning of the liquid collection box 200.

[0090] In some embodiments, the drip tube 3 may include a slow-flow section 31, which is inclined downward in the direction close to the part 6 to be cleaned.

[0091] For example, such as Figure 9 and Figure 10 As shown, the liquid collection box 200 can be set above the part 6 to be cleaned. The inlet 13 end of the drip tube 3 is connected to the liquid collection box 200, and the outlet 14 end is located on the side of the slow flow section 31 away from the inlet 13 end. The slow flow section 31 extends obliquely downward to the top of the part 6 to be cleaned so that the liquid can drip onto the part 6 to be cleaned.

[0092] This embodiment of the present disclosure provides a downwardly extending slow-flow section 31 in the drip tube 3, which can extend the flow path of the liquid in the drip tube 3, thereby achieving slow liquid flow and improving the stability of the liquid flow rate when the drip tube 3 drips onto the part to be cleaned 6, thus improving the cleaning effect. At the same time, it can also reduce the impact force on the part to be cleaned 6 when the liquid drips, and improve the problem of excessive liquid flow causing liquid droplets to splash and form liquid marks on the products (such as copper foil) of the workbench.

[0093] In some embodiments, the slow-flow section 31 may include a plurality of slow-flow nodes 32, the inner surface of which is an outwardly convex arc surface, thereby extending the flow path of the liquid in the drip tube 3 and enabling the slow flow of the liquid.

[0094] The drip tube 3 can be rotatably connected to the liquid collection box 200. When the liquid in the liquid collection tank is guided to the part to be cleaned 6 by the drip tube 3, the drip tube 3 can be rotated arbitrarily according to the position of the part to be cleaned 6 so as to adjust the outlet 14 end of the drip tube 3 to the top of the part to be cleaned 6, thereby improving the adaptability of the drip tube 3 to the part to be cleaned 6 in different positions.

[0095] In some embodiments, the diameter of the drip irrigation tube 3 can be in the range of 1cm-1.5cm, and the length of the drip irrigation tube 3 can be in the range of 20cm-30cm.

[0096] For example, the diameter of the drip irrigation tube 3 can be 1cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm, 1.5cm, etc., and the length of the drip irrigation tube 3 can be 20cm, 21cm, 22cm, 23cm, 24cm, 25cm, 26cm, 27cm, 28cm, 29cm, 30cm, etc., depending on the actual situation.

[0097] In some embodiments, a scraper 5 may be provided on the liquid inlet side of the liquid collection box 200. The scraper 5 is connected to the liquid collection box 200 and spaced apart from the liquid outlet side of the liquid collection box 200. The scraper 5 is configured to contact the workbench for scraping off the liquid on the workbench and guiding the liquid into the liquid collection tank.

[0098] When the working platform in this disclosure is a foil production machine, the scraper 5 can be configured to contact the copper foil on the working platform to scrape off the liquid on the copper foil.

[0099] The size of the scraper 5 can be adapted to the size of the liquid inlet side of the liquid collection box 200.

[0100] Specifically, the length of the scraper blade 5 can be the same as the length of the liquid inlet side of the liquid collection box 200, thereby improving the efficiency of scraping liquid.

[0101] In addition, when the scraper 5 is used to scrape off the liquid on the copper foil, the length of the scraper 5 can be adapted to the length of the copper foil to improve the efficiency of removing liquid from the copper foil.

[0102] For example, the dimensions of the liquid collection tank in this embodiment of the present disclosure can be: a rectangle with a length of 1.1m-1.4m, a width of 0.3m-0.4m, and a height of 0.1m-0.15m, and the volume of the liquid collection tank can be 0.033m³.3 -0.084m 3 The inlet side and outlet side are located on opposite sides of the width of the liquid collection tank. However, this is not a limitation; the liquid collection tank in this embodiment can also be of other shapes and sizes, depending on the actual situation.

[0103] The material used to manufacture the wiper blade 5 may include PVC (polyvinyl chloride sheet), but is not limited to it. Other materials with good impact resistance and rigidity besides PVC may also be included in the embodiments disclosed herein.

[0104] In some embodiments, the scraper 5 can be tilted downwards in the direction near the liquid outlet side of the collection box 200, so that the liquid scraped off the worktable can automatically flow into the collection tank under the guidance of the scraper 5. However, it is not limited to this, the scraper 5 can also be disposed horizontally on the collection box 200, and the specific configuration can be determined according to the actual situation.

[0105] In some embodiments, a plurality of scraper blades 5 may be provided on the liquid inlet side of the liquid collection box 200, which are spaced apart along the depth direction of the liquid collection groove.

[0106] For example, such as Figure 9 As shown, a scraper 5 can be installed at the top and bottom of the liquid collection box 200, which can reduce the liquid residue on the worktable.

[0107] It should be noted that the top of the liquid collection box 200 can refer to the top wall of the liquid collection tank, and the bottom of the liquid collection box 200 can refer to the bottom wall of the liquid collection tank.

[0108] This disclosure also provides a foil production system, which may include a foil production apparatus and any of the cleaning devices described above. The foil production apparatus can be used to produce copper foil, and the cleaning device is configured to clean the component 6 to be cleaned in the foil production apparatus.

[0109] Specifically, the foil production device may include: a cathode roller, an acid-squeezing roller, a water-squeezing roller, an anode tank, guide wheels, and O-rings. The specific working principle of the foil production device can be as follows: copper foil is electrolytically plated onto the cathode roller in the anode tank, and the copper foil is rotated out during the rotation of the cathode roller. It then passes through the acid pickling, acid-squeezing roller, water washing, and water-squeezing roller in sequence before being peeled off on the stripping roller.

[0110] Among them, the through-hole structure on the cleaning box 100 can scrape off impurities such as crystals on the O-ring, thereby improving production abnormalities such as copper foil tearing and denting caused by impurities on the O-ring, and thus improving production efficiency and yield.

[0111] In addition, when the cleaning device includes both a cleaning box 100 and a liquid collection box 200, the liquid on the copper foil can be scraped off by the scraper 5 and guided into the liquid collection box 200. The washing water collected in the liquid collection tank can be guided to the O-ring on the guide wheel by the drip irrigation tube 3 connected to the flow port 21 of the liquid collection box 200. This is to initially clean away the larger impurities on the O-ring and the guide wheel, and improve the problems of copper foil tearing, unevenness, or even pinholes caused by crystallization and other impurities on the O-ring and the guide wheel. At this time, the foreign matter attached to the O-ring can be basically removed. The excess liquid in the liquid collection tank can be introduced into the external waste liquid collection device for waste liquid treatment through the flow port 21 which is not connected to the drip irrigation tube 3. Furthermore, an O-ring not set on the guide wheel can be installed through the cleaning box 100 to deeply remove stubborn foreign matter (such as crystals, residual copper, etc.) on the O-ring using the through-hole structure on the cleaning box 100. This reduces the possibility of foreign matter falling off the O-ring during the foil production process, improves the copper foil production yield, and reduces the need to obtain pure water from the outside to clean the parts to be cleaned 6, thereby reducing the cleaning and production costs of the foil production system.
