Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleaning equipment for copper foil production, specifically to a cleaning treatment device for processing ultra-thin carrier copper foil. Background Technology
[0002] Copper foil, a key basic material for electronic products such as lithium-ion batteries and printed circuit boards (PCBs), directly affects the yield and product performance of subsequent coating, lamination, and other processes due to its surface cleanliness. In the copper foil production process, the raw foil after electrolytic deposition requires multiple post-processing steps. The cleaning stage aims to remove residual electrolyte, organic additives, oxides, and mechanical impurities from the copper foil surface to prevent corrosion, oxidation, or decreased interfacial adhesion. Traditional cleaning processes rely on chemical immersion, high-pressure water rinsing, or mechanical brushing, but these methods suffer from high cleaning agent consumption, high wastewater treatment costs, and the risk of scratching the copper foil surface. With the development of copper foil towards ultra-thin (below 6μm) and high tensile strength, higher demands are placed on the refined control, environmental friendliness, and energy efficiency of cleaning equipment. In recent years, the industry has gradually introduced new technologies such as ultrasonic cavitation cleaning, membrane separation circulating water systems, and online monitoring. By optimizing the distribution of cleaning media, achieving closed-loop water circulation, and real-time feedback control, these technologies are driving the upgrading of cleaning equipment towards high efficiency, low consumption, and intelligence.
[0003] Chinese patent application publication number CN114990641A discloses a carrier ultrathin copper foil and its preparation method, which describes the specific process of copper foil cleaning. Chinese patent application publication number CN116673254A discloses a surface cleaning device and method for copper foil before winding. In this device, the copper foil is first guided and conveyed by multiple guide rollers in the main structure. A bending component in the spray cleaning structure changes the shape of the copper foil to avoid damage from the spray, while a nozzle assembly sprays water onto the copper foil for cleaning. A water removal structure scrapes away residual water stains on the copper foil, and finally, a drying component dries the copper foil with air, completing the cleaning process. However, this device separates the water removal structure and the drying component, resulting in high overall complexity and making maintenance difficult.
[0004] To address the aforementioned problems, this utility model proposes a cleaning and treatment device for processing ultra-thin carrier copper foil. Utility Model Content

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0027] Reference Figures 1-7 A cleaning and treatment device for processing ultra-thin carrier copper foil includes a main body 1, a spraying and washing mechanism 2, and a dewatering mechanism 3. The dewatering mechanism 3 can be detached from the main body 1. The dewatering mechanism 3 includes a mounting block 31 at its bottom, a scraper 32, a sponge roller 33, and a drying mechanism inside the dewatering mechanism 3. The main body 1 has a mounting slot 11 adapted to the mounting block 31, and the mounting block 31 and the main body 1 have fixing slots 12 on their sides. When the mounting block 31 is inserted into the mounting slot 11, the fixing slots 12 on their sides overlap. A U-shaped pin 13 is inserted into the fixing slot 12. The spraying and washing mechanism 2 includes an upper spray head and a lower spray head on the main body 1.
[0028] In existing technologies, the dewatering device and the drying device are separate units, which increases the overall complexity of the cleaning device and makes it inconvenient to remove them from the cleaning device, thus making maintenance difficult. To address this problem, this application provides a cleaning device for processing ultra-thin carrier copper foil. This device integrates a main body 1, a spraying mechanism 2, and a dewatering mechanism 3, forming a complete copper foil cleaning system. The main body 1 includes a conveying channel to support and guide the transport of the copper foil.
[0029] The main body 1 is equipped with an upper nozzle and a lower nozzle, which spray water to clean the upper and lower surfaces of the copper foil, respectively. The cleaning solution is sprayed evenly onto the copper foil surface through the nozzle at an appropriate pressure and angle, effectively removing stains and impurities from the copper foil surface while avoiding damage to the copper foil.
[0030] The bottom of the water removal mechanism 3 is equipped with a mounting block 31, which matches the mounting slot 11 reserved on the main body 1, so that the water removal mechanism 3 can be stably installed on the main body 1. At the same time, both the mounting block 31 and the side of the main body 1 are provided with fixing slots 12. When the mounting block 31 is fully inserted into the mounting slot 11, the mounting block 31 and the fixing slot 12 on the side of the main body 1 will overlap. At this time, a U-shaped pin 13 can be inserted to further fix the water removal mechanism 3 and ensure its stability during operation.
[0031] The dewatering mechanism 3 is equipped with a scraper 32, a sponge roller 33, and a drying mechanism, which can efficiently remove residual moisture from the copper foil. The scraper 32 is responsible for initially scraping away excess water, while the sponge roller 33, with its soft material and appropriate pressure, further absorbs and dries the tiny water droplets on the surface of the copper foil. Finally, the drying mechanism uses airflow to quickly dry the residual moisture on the surface of the copper foil, ensuring that the copper foil can quickly return to a dry state after cleaning.
[0032] Throughout the cleaning process, the copper foil passes through the conveying channel of the main body 1, sequentially through the spraying mechanism 2 and the dewatering mechanism 3, completing the two key steps of cleaning and dewatering.
[0033] Reference Figures 1-6 As shown: The scraper 32 includes a lower scraper 322 and an upper scraper 321. The lower scraper 322 is fixedly installed in the water removal mechanism 3. The inner side wall of the water removal mechanism 3 is provided with a moving groove. The upper scraper 321 is connected to two pull rods 41 on both sides, and the pull rods 41 are slidably connected to the moving groove.
[0034] The upper scraper 321 is slidably connected to the moving groove via the pull rods 41 connected on both sides, so that the upper scraper 321 can slide up and down in the moving groove according to actual needs, adjusting the contact pressure and position between it and the copper foil, thereby more effectively removing moisture or stains that are difficult to remove from the surface of the copper foil.
[0035] Reference Figure 6 As shown: A guide rod 43 is provided in the moving groove, and a guide groove 42 adapted to the guide rod 43 is opened on the pull rod 41. A return spring is sleeved on the guide rod 43.
[0036] The guide rod 43 effectively prevents the upper scraper 321 from shifting or shaking, thereby ensuring that the upper scraper 321 has a uniform water scraping effect on the copper foil surface.
[0037] Meanwhile, a return spring is also fitted on the guide rod 43. The return spring can ensure that the upper scraper 321 can always be pressed against the copper foil, thereby ensuring the water removal efficiency.
[0038] Reference Figures 1-6 As shown: The dewatering mechanism 3 is provided with a limiting mechanism 5; the limiting mechanism 5 includes a limiting block 52 located on the top of the dewatering mechanism 3 and a limiting slot 51 opened on the pull rod 41.
[0039] Under the action of the return spring, the upper scraper 321 always tends to move in the direction of abutting the lower scraper 322. When it is necessary to pass the copper foil between the upper scraper 321 and the lower scraper 322, pull the pull rod 41 until the limit slot 51 is exposed outside the dewatering mechanism 3. At this time, the limit block 52 is inserted into the limit slot 51, and the upper scraper 321 and the lower scraper 322 are in a state of being separated by a distance. At this time, the copper foil can be passed through the upper scraper 321 and the lower scraper 322.
[0040] Reference Figures 1-4 As shown: The U-shaped pin 13 has an anti-disengagement insertion hole 131 at its open end, and an anti-disengagement insertion block 132 is slidably connected in the insertion hole.
[0041] When the U-shaped pin 13 is inserted into the fixed slot 12 to fix the water removal mechanism 3 to the main body mechanism 1, the anti-detachment block 132 is inserted into the anti-detachment hole 131 provided at the open end of the U-shaped pin 13 to prevent the U-shaped pin 13 from coming out of the fixed slot 12.
[0042] Reference Figures 1-3 As shown: The main body 1 has permeable holes 6 to prevent water accumulation.
[0043] When the spray cleaning mechanism 2 sprays water to clean the copper foil, excess water or cleaning fluid may flow along the contact surface between the copper foil and the main body mechanism 1. The presence of the water permeable hole 6 allows this excess water to smoothly penetrate the main body mechanism 1 and flow into the collection system below. This collection system can be a cavity that can hold a certain volume of water, thus maintaining the drying of the main body mechanism 1 and ensuring a smooth cleaning process.
[0044] Reference Figures 1-7 As shown: the upper scraper 321 and the lower scraper 322 are fixedly connected to the two ends of the mounting plate, and a quick-release mechanism 7 is provided between the sponge roller 33 and the mounting plate.
[0045] The sponge roller 33 can be easily replaced using the quick-release mechanism 7.
[0046] Reference Figures 1-7 As shown: A sleeve is provided on the mounting plate, and the quick-release mechanism 7 includes a moving rod 71 located at one end of the sponge roller 33. A cavity is opened at one end of the shaft of the sponge roller 33 near the moving rod 71, and a return spring is provided in the cavity. The moving rod 71 is inserted into the sleeve.
[0047] When the sponge roller 33 needs to be disassembled for replacement or maintenance, the operator only needs to drive the shaft of the sponge roller 33 towards the moving rod 71 to overcome the elastic force of the return spring, so that the shaft at the other end of the sponge roller 33 is completely disengaged from the sleeve. At this time, the sponge roller 33 can be easily removed from the mounting plate.
[0048] Working principle: The device integrates the main body 1, the spraying mechanism 2, and the dewatering mechanism 3, forming a complete copper foil cleaning system. During the cleaning process, the copper foil is transported through the conveying channel of the main body 1.
[0049] First, the copper foil passes through the spray cleaning mechanism 2, which includes an upper spray head and a lower spray head mounted on the main body 1, respectively spraying water to clean the upper and lower surfaces of the copper foil. The cleaning fluid is sprayed evenly onto the copper foil surface at appropriate pressure and angle, effectively removing stains and impurities from the copper foil surface.
[0050] Subsequently, the copper foil enters the dehydration mechanism 3. The bottom of the dehydration mechanism 3 is equipped with a mounting block 31 that matches the mounting slot 11 pre-drilled on the main body 1, allowing the dehydration mechanism 3 to be securely mounted on the main body 1. The dehydration mechanism 3 is internally equipped with a scraper 32, a sponge roller 33, and a drying mechanism. The scraper 32 includes a lower scraper 322 and an upper scraper 321 that can slide up and down. The upper scraper 321 is slidably connected to the moving groove via a pull rod 41, and its contact pressure and position with the copper foil can be adjusted according to actual needs to initially remove excess water. The sponge roller 33, with its soft material and appropriate pressure, further absorbs and dries the tiny water droplets on the surface of the copper foil. Finally, the drying mechanism uses airflow to quickly dry the residual moisture on the surface of the copper foil, ensuring that the copper foil can quickly return to a dry state after cleaning.
[0051] Finally, to facilitate the replacement of the sponge roller 33, mounting plates are fixedly connected to both ends of the upper scraper 321 and the lower scraper 322, and a quick-release mechanism 7 is provided between the mounting plate and the sponge roller 33. Through the quick-release mechanism 7, the operator can easily remove the sponge roller 33 from the mounting plate for replacement or maintenance.
[0052] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
