Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production and manufacturing equipment, in particular to a copper sinking tank. Background Art

[0002] Currently, in the production of aluminum batteries, copper foil is usually used as a component of the negative electrode because of its strong conductivity, soft texture, and non-reaction with lithium.

[0003] Chemical copper deposition is a common method for preparing composite copper foil. It is to contact the activated substrate with a chemical solution containing copper ions, and use chemical reactions to reduce the copper ions and deposit them on the surface of the substrate. In the existing chemical copper deposition equipment, a copper deposition tank is required to place the solution. The deposition work is completed by passing the substrate through the copper deposition tank and contacting the solution therein. The existing copper deposition tank is usually fixed on the production line or production line equipment. When changing the solution, the solution can only be exported to other places through pipelines. When cleaning the copper deposition tank after exporting the solution, since the copper deposition tank is fixedly installed, it is inconvenient to clean it, resulting in some solution residues in the corners and edges inside, affecting subsequent work; in addition, since the chemical solution for copper deposition is usually disposable, the existing copper deposition tank consumes a large amount of solution, resulting in high costs.

The first adjustment structure can adjust the horizontal position of the guide roller and the transfer roller, and the second adjustment structure can adjust the vertical position. During installation or subsequent work, the first adjustment structure and the second adjustment structure can be used to perform position adjustment and calibration to ensure that each guide roller and transfer roller are in the same direction, thereby ensuring the normal transportation of the coiled material and avoiding the displacement of the coiled material.

[0015] Furthermore, the first adjustment structure and the second adjustment structure each include a sliding block and a fixed seat, the sliding block is slidably connected to the fixed seat, the ends of the guide roller and the transfer roller are connected to the sliding block, and fixing pieces for fixing the sliding block are provided on both sides of the fixed seat.

The prior art usually adopts an integrated design, that is, a container-type structure is directly used to hold the solution. When the solution is replaced, a pipeline is usually used to guide the solution from the container to other places. Since the container-type structure is usually installed on the equipment or production line, it is inconvenient to carry out subsequent cleaning work, resulting in some solution residues in the corners and edges of the container, which is difficult to clean and affects subsequent work.

Therefore, the copper deposition tanks of the present application are usually multiple and connected in sequence for use, such as Figure 1 As shown in the figure, only the individual copper sinking tank is described below. Embodiment 1:

[0040] Please refer to Figures 1 to 6 In a non-limiting embodiment, a copper deposition tank is provided, comprising a tank body 1, a guide mechanism 2 and a circulation mechanism 3, wherein the circulation mechanism 3 is arranged on one side of the tank body 1; the tank body 1 comprises a placement box 11 and a solution tank 12, wherein the solution tank 12 is arranged in the placement box 11 and is detachably connected to the placement box 11, and the two sides of the solution tank 12 are inclined walls 13 arranged obliquely, and a cavity is formed between the inclined walls 13 and the two side walls in the placement box 11; the guide mechanism 2 comprises a plurality of guide rollers 21, wherein the plurality of guide rollers 21 are distributed in the solution tank 12 along the same axial direction, and the two ends of the plurality of guide rollers 21 pass through the solution tank 12 and the placement box 11; the circulation mechanism 3 is arranged on the outside of the placement box 11, and the circulation mechanism 3 comprises a power device 31 and a circulation pipeline 32, wherein the power device 31 is connected to the circulation pipeline 32, and the circulation pipeline 32 is connected to the solution tank 12.

[0041] In this embodiment, the solution tank 12 is used to hold the chemical solution used in chemical copper plating. The guide roller 21 is arranged in the solution tank 12 to drive the coil material through the solution tank 12 so that the surface of the coil material is fully in contact with the chemical solution, so that the copper ions adhere to the surface of the coil material to complete the chemical copper plating; the top of the placement box 11 is open, and the solution tank 12 is installed inside the placement box 11 and is detachably connected to the placement box 11. When changing the solution, the solution tank 12 can be taken out to load or pour out the solution, which is more convenient to operate. At the same time, when cleaning after the work is completed, the solution tank 12 can be taken out for cleaning work, and the cleaning effect is better and it is not easy to have residues; the inner side wall of the placement box 11 is vertically arranged, and the inclined walls 13 on both sides of the solution tank 12 are inclined to the side walls of the placement box 11, that is, after the solution tank 12 is placed in the placement box 11, the inclined walls 13 on both sides form a A certain angle is set so that a certain cavity is retained on both sides of the solution tank 12 and between the two sides of the placement tank, so that the volume of the solution tank 12 is greatly reduced compared with the placement box 11, thereby reducing the consumption of chemical solution and saving costs without affecting the contact between the coil material and the solution; in addition, a circulation mechanism 3 is provided on the outside of the placement box 11, and the circulation pipeline 32 is connected to the solution tank 12. The power provided by the power device 31 can make the chemical solution in the solution tank 12 pass through the circulation pipeline 32 and then return to the solution tank 12. The external power is introduced through the power device 31 to make the chemical solution form a circulation flow, which plays a certain stirring role, thereby increasing the fluidity of the solution in the solution tank 12, which helps to maintain the uniform distribution of various components in the solution and promote the progress of chemical reactions. At the same time, the increase in the fluidity of the solution also helps to improve the uniformity of copper ions in the solution when adhering to the coil.

The reason for this arrangement is that, since the guide roller 21 is arranged in the solution tank 12, the two side surfaces parallel to the end faces of the guide roller 21 need to be arranged vertically to make way for the placement of the guide roller 21.

[0044] In this embodiment, a gap is left between the bottom of the solution tank 12 and the bottom surface of the placement box 11 .

[0045] After the solution tank 12 is connected to the placement box 11, a certain distance is maintained between the bottom of the solution tank 12 and the bottom surface of the inner side of the placement box 11. The distance can prevent the bottom of the solution tank 12 from colliding with the placement box 11 when the solution tank 12 is placed in the placement box 11, thereby avoiding damage to the solution tank 12. At the same time, the volume of the solution tank 12 can be further reduced to reduce solution consumption.

[0046] In this embodiment, three guide rollers 21 are provided, two of which are provided at the lower part of the solution tank 12 and one is provided at the upper part. The upper and lower guide rollers 21 are staggered in the solution tank 12. Figure 6 The direction shown moves from left to right.

[0048] In this embodiment, two power devices 31 are provided and spaced apart on one side of the placement box 11 . Both power devices 31 are connected to a circulation pipeline 32 , thereby ensuring that the solutions on both sides of the solution tank 12 can be processed evenly, which helps to ensure the overall fluidity of the solution in the solution tank 12 .

[0049] It should be noted that in the figure, only the power device 31 and the circulation pipeline 32 are arranged at the front position of the copper deposition tank, which can meet the fluidity requirements of the solution in the solution tank 12. In the specific implementation, if there are further fluidity requirements, the power device 31 and the circulation pipeline 32 can be arranged on both sides of the copper deposition tank.

[0050] In this embodiment, the guide mechanism 2 includes two transfer rollers 22, and the two transfer rollers 22 are respectively arranged on both sides of the top of the placement box 11.

The first adjustment structure 23 can adjust the horizontal position of the guide roller 21 and the transfer roller 22, and the second adjustment structure 24 can adjust the vertical position. When installing the guide roller 21 and the transfer roller 22, or in subsequent work, the first adjustment structure 23 and the second adjustment structure 24 can be used to adjust and calibrate the position to ensure that each guide roller 21 and the transfer roller 22 are in the same direction, thereby ensuring the normal transportation of the coiled material and avoiding deviation in the transportation of the coiled material.

[0053] In this embodiment, the first adjusting structure 23 includes a first sliding block 231 and a first fixed seat 232, the first sliding block 231 is slidably connected to the first fixed seat 232, and the left and right sides of the first fixed seat 232 are provided with first fixing members 233 for fixing the first sliding block 231; the second adjusting structure 24 includes a second sliding block 241 and a second fixed seat 242, the second sliding block 241 is slidably connected to the second fixed seat 242, and the upper and lower sides of the second fixed seat 242 are provided with second fixing members 243 for fixing the second sliding block 241.

[0054] One end of the guide roller 21 and the transfer roller 22 is connected to the first sliding block 231, and the other end is connected to the second sliding block 241. By sliding the first sliding block 231 and the second sliding block 241, the direction and position of the guide roller 21 and the transfer roller 22 can be adjusted so that the directions of the guide roller 21 and the transfer roller 22 are always consistent to ensure the normal transportation of the coiled material. The first fixing member 233 and the second fixing member 243 are used to fix the first sliding block 231 and the second sliding block 241 after the guide roller 21 and the transfer roller 22 are adjusted to the appropriate position.

[0055] The first sliding block 231 can only slide left and right on the first fixing seat 232 (i.e. Figure 5 In the horizontal left and right direction shown in the figure), the first fixing member 233 is arranged on the left and right sides of the first fixing seat 232 to limit the left and right movement of the first sliding block 231, and the second sliding block 241 can only slide up and down on the second fixing seat 242. The second fixing member 243 is arranged on the upper and lower sides of the second fixing seat 242 to limit the up and down movement of the second sliding block 241. Through the above arrangement, the respective adjustment functions of the first adjustment structure 23 and the second adjustment structure 24 are clarified, and they can be better selected and used according to needs during specific adjustment.

[0056] Specifically, side plates are provided on the left and right sides (upper and lower sides) of the fixing member, and the fixing member adopts bolts and is threadedly connected with the side plates. By adjusting the bolts, the sliding block can be fixed or loosened, thereby adjusting.

[0058] The pillars 25 are arranged at intervals on both sides of the placement box 11 and correspond to the positions of the first adjustment structure 23 and the second adjustment structure 24. The first adjustment component and the second adjustment component are installed on both sides of the placement box 11 through the pillars 25, wherein the fixing seat is connected to the pillars 25, that is, the first adjustment component and the second adjustment component are connected to the pillars 25 through their respective fixing seats.

[0059] In this embodiment, a pressure roller 26 is provided on one side of the transfer roller 22. The pressure roller 26 is arranged tangentially to the transfer roller 22. The coil passes through the tangent point with the transfer roller 22. The pressure roller 26 can smooth the surface of the coil treated with the chemical solution to make it smoother. In addition, since the surface of the coil passing through the solution tank 12 usually carries a certain solution, the coil is prone to slipping. By setting the pressure roller 26, a certain pressure can be applied to the coil passing through the transfer roller 22 to reduce the occurrence of slipping.

[0060] It should be noted that, since there is more solution on the surface of the coil when it is just sent out of the solution tank 12, it is easy to cause the coil to slip. Therefore, the pressure roller 26 in this embodiment is only provided on the side of the transfer roller 22 on the side where the coil is sent out of the solution tank 12. Of course, the transfer roller 22 on both sides can also be equipped with a pressure roller 26.

[0062] The support rod 27 is vertically fixed on the pillar 25, and the sliding rod 271 can slide up and down along the direction of the support rod 27, thereby driving the pressure roller 26 connected to the sliding rod 271 to move up and down. When dealing with pressure rollers 26 of different sizes, the position of the pressure roller 26 can be adjusted by the sliding rod 271 so that the pressure roller 26 and the transfer roller 22 remain tangent.

[0063] In this embodiment, the placement box 11 is provided with a sealing structure 111 at the position where the guide roller 21 passes through. The surface of the placement box 11 is provided with a through hole for the guide roller 21 to pass through, and the sealing structure 111 is provided at the through hole to seal and prevent leakage. The figure only shows the sealing structure 111 on the front of the placement box 11, and a corresponding sealing structure 111 is also provided on the back of the placement box 11; wherein, the sealing structure 111 in this embodiment is only provided at both ends of the guide roller 21 at the lower position in the solution tank 12. Since the solution in the solution tank 12 does not need to be filled, an opening can be provided above the placement box 11 and the solution tank 12 for the two ends of the guide roller 21 located above the solution tank 12 to pass through, so there is no need to provide a sealing structure 111 at both ends of the guide roller 21 at the upper position. Embodiment 2:

[0064] Please refer to Figure 7 In this embodiment, five guide rollers 21 are provided, three of which are provided below the solution tank 12 and two are provided above the solution tank 12.
