[0031] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments to make the advantages and features of the present invention easier for those skilled in the art to understand. Obviously, the embodiments described in this application are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0032] See also Figures 1 to 5 The chemical treatment tank shown includes at least a first treatment tank 1. The first treatment tank 1 comprises a first tank body 11 having a first tank cavity 1a. The first tank body 11 is provided with a reflux port and a liquid extraction port communicating with the first tank cavity 1a. Liquid enters the first tank cavity 1a through the reflux port and, under the action of a pumping device, flows out of the liquid extraction port and is supplied to another treatment tank, thereby achieving liquid recycling.

[0033] Specifically, the chemical treatment tank also includes a second treatment tank 2, which is the other treatment tank mentioned above. The second treatment tank 2 includes a second tank body 21 having a second tank cavity, the second tank cavity having a main chamber 2a and a first chamber 2b. The main chamber 2a has a liquid outlet, and the first chamber 2b is located below the liquid outlet. When the product to be processed is chemically treated, the main chamber 2a is filled with a liquid for chemical treatment. The product to be processed is transferred or placed in the main chamber 2a to contact the liquid for chemical treatment. For example, when electroplating a battery cell, the main chamber 2a is filled with a plating liquid. When the battery cell contacts the plating liquid in the main chamber 2a, the electroplating treatment is achieved. In some embodiments, the product to be processed can be translated in the main chamber 2a along the length of the second tank body 21. During processing, the product to be processed is transferred to the main chamber 2a along the length of the second tank body 21 by a conveying mechanism and is contacted with the liquid for processing. After completion, the product is transferred out of the main chamber 2a by the conveying mechanism. When there is too much liquid in the main chamber 2a, the excess liquid flows from the liquid outlet into the first chamber 2b for easy recycling.

[0034] Specifically, the bottom of the first chamber 2b is provided with a drain port 25 connected thereto, and the liquid collected in the first chamber 2b is discharged outward through the drain port 25; the bottom of the main chamber 2a is also provided with a liquid supply port (not shown in the figure) for supplying liquid to the main chamber 2a. The above-mentioned drain port 25 is connected to the reflux port via the reflux pipe 3, and the liquid extraction port is connected to the liquid supply port via the liquid supply pipe (not shown in the figure). In this way, the liquid overflows from the main chamber 2a of the second treatment tank 2 to the first chamber 2b, and then enters the first tank chamber 1a of the first treatment tank 1 through the drain port 25, the reflux pipe 3 and the reflux port. Then, under the action of the pump device, the liquid circulates from the liquid extraction port through the liquid supply pipe and the liquid supply port to the main chamber 2a, realizing the recycling of the liquid.

[0035] In the chemical treatment tank provided by the present application, the first treatment tank 1 also includes a baffle assembly arranged in the first tank cavity 1a, and the baffle assembly includes a plurality of baffles 12 arranged at intervals. All the baffles 12 cooperate with each other to form a liquid flow path for the liquid to flow from the reflux port to the liquid extraction port. This allows the liquid to flow along the liquid flow path in the process of reaching the liquid extraction port from the reflux port, thereby making the liquid flow in the first tank cavity 1a relatively stable, thereby avoiding or reducing the generation of foam in the first tank cavity 1a. When the liquid is circulated to the main chamber 2a for use, it contains less or even no foam, thereby reducing or eliminating the generation of foam from the root, so that there is no need to use a foam breaker or add a defoaming agent to eliminate foam.

[0036] Specifically, see Figure 3As shown, all the baffles 12 in the baffle assembly are spaced apart along a first direction, and all the baffles 12 extend along a second direction, the first direction intersecting the second direction. In this embodiment, the first direction and the second direction are perpendicular to each other, and can specifically be the length direction and width direction of the first treatment tank 1. When setting up the first treatment tank 1, one end of any baffle 12 abuts against the side wall of the first tank body 11, and the other end has a certain distance from the other side wall of the first tank body 11 to allow the liquid to flow only along the preset direction. In addition, the height of each baffle 22 should be higher than the height of the liquid level when the first tank body 11 is in operation; the bottom wall 111 of the first tank cavity 1a extends obliquely toward one side to facilitate the emptying of the liquid in the first tank cavity 1a.

[0037] Specifically, in this embodiment, see Figure 3 As shown, the first groove cavity 1a has a first side wall 13 and a second side wall 14 arranged opposite to each other in the above-mentioned second direction. Among the two adjacent baffles 12, one end of one baffle 12 is against the first side wall 13 and the other end is spaced apart from the second side wall 14, and one end of the other baffle 12 is against the second side wall 14 and the other end is spaced apart from the first side wall 13. In this way, the multiple baffles 12 cooperate with each other to guide the liquid, so that the liquid in the first groove cavity 1a can flow smoothly from the reflux port to the liquid extraction port along the multiple baffles 12.

[0038] In this embodiment, two groups of reflux ports are provided along the first direction, and the two groups of reflux ports are respectively provided at two different ends of the first groove cavity 1a; one group of liquid extraction ports is provided, and the liquid extraction port is provided between the two groups of reflux ports, and an above-mentioned liquid flow path is formed between each reflux port and the liquid extraction port.

[0039] In this embodiment, the chemical treatment tank further includes a liquid extraction pipe 5 extending in the second direction and located within the first tank cavity 1a. One end of the liquid extraction pipe 5 is connected to a liquid extraction port or a liquid supply pipe. The liquid extraction pipe 5 is provided with a plurality of liquid holes 51 communicating with the lumen of the liquid extraction pipe 5. Liquid enters the liquid extraction pipe 5 through the plurality of liquid holes 51, resulting in a relatively stable flow rate. Here, the baffle assembly includes an intermediate baffle, which is one of a plurality of baffles 12. Two sets of liquid flow paths are formed on either side of the intermediate baffle. The liquid extraction pipe 5 and the intermediate baffle extend along the same length, with a gap between them. Thus, liquid enters the first tank cavity 1a through the reflux ports at both ends. Subsequently, under the guidance of the plurality of baffles 12, it flows along the liquid flow path toward the liquid extraction pipe 5, passes through the plurality of liquid holes, and enters the liquid extraction pipe 5. It is then supplied to the main chamber 2a through the liquid extraction pipe.

[0040] As shown in the accompanying drawings, in the chemical treatment tank, the second treatment tank 2 also includes a guide plate assembly 23 for buffering the liquid flowing out of the liquid outlet and then introducing it into the first chamber 2b. The guide plate assembly 23 includes a plurality of guide plates distributed in sequence along the vertical direction, so that the liquid can flow through the upper guide plate to the lower guide plate, so that the liquid flows into the first chamber 2b after multiple buffering. In this way, when the chemical treatment tank is in operation, after the liquid in the main chamber 2a flows out from the liquid outlet, the liquid passes through the multiple guide plates of the guide plate assembly 23, and then enters the first chamber 2b after multiple buffering from top to bottom. This makes the drop in the liquid from top to bottom in the process of flowing to the first chamber 2b smaller, which can avoid or reduce the generation of foam as much as possible. The liquid entering the first chamber 2b contains less foam or even no foam when it is returned to the main chamber 2a for use, further reducing or eliminating the generation of foam from the root.

[0041] In the chemical treatment tank provided in this embodiment, the second tank cavity also includes a second chamber 2c located on at least one side of the main chamber 2a. The upper part of the second chamber 2c is connected to the main chamber 2a through the liquid outlet. The first chamber 2b is located below the second chamber 2c and is connected to the second chamber 2c. After the liquid in the main chamber 2a flows out from the liquid outlet, it first enters the second chamber 2c and then flows downward into the first chamber 2b.

[0042] An overflow plate 24 is disposed between the main chamber 2a and the second chamber 2c. This overflow plate 24 is provided with a plurality of through-holes 241 extending through its thickness. These through-holes 241 establish fluid communication between the second chamber 2c and the main chamber 2a. These through-holes 241 serve as the aforementioned liquid outlets. Liquid in the main chamber 2a flows through these through-holes 241 into the second chamber 2c. This results in a more gradual flow rate when the liquid enters the second chamber 2c, further reducing or preventing the formation of foam.

[0043] The second chamber 2c is located on one or both sides of the main chamber 2a along the width of the second trough 21. When there are two second chambers 2c, they are spaced apart along the width of the second trough 21, each communicating with the main chamber 2a at its upper portion. When there is only one second chamber 2c, the second chamber 2c is located side by side with the main chamber 2a. When there is excess liquid in the main chamber 2a, the excess liquid can flow from the upper portion of the second chamber 2c into the second chamber 2c, and then flow into the first chamber 2b.

[0044] The second processing tank 2 also includes a partition assembly 22, which is used to separate the second tank cavity into a main chamber 2a, a first chamber 2b, and a second chamber 2c. The partition assembly 22 includes at least one partition 221 and a bottom plate 222. The partition 221 is vertically arranged in the second tank body 21 and has a certain distance from the sidewall of the second tank body 21 to form the second chamber 2c. The bottom plate 222 is horizontally arranged in the second tank body 21 and is connected to the partition 221 and the second tank body 21 on both sides, or is connected to two partitions 221 on both sides. The bottom plate 222 has a certain distance from the bottom of the second tank body 21 to vertically divide the second tank body 21 into the main chamber 2a and the first chamber 2b. In this embodiment, there are two second chambers 2c arranged on both sides of the main chamber 2a. The two vertical partitions 221 and the two sidewalls of the second tank body 21 each form a second chamber 2c. The bottom plate 222 is connected between the two partitions 221.

[0045] As shown in the accompanying drawings, the guide plate assembly 23 includes a plurality of guide plates distributed sequentially in the vertical direction, and at least some of the guide plates are located in or extend into the second chamber 2c. Specifically, in some embodiments, all guide plates are located in the second chamber 2c; in other embodiments, the guide plate located at the top extends into the main chamber 2a to guide the liquid in the main chamber 2a to the top guide plate in a manner without a drop; in other embodiments, the guide plate located at the bottom extends into the first chamber 2b; in some other embodiments, guide plates are provided in both the first chamber 2b and the second chamber 2c. This allows the liquid to be guided and buffered during its passage through the second chamber 2c, reducing the generation of foam. Among the multiple guide plates of the guide plate assembly 23, each guide plate has a suspended end, which can be understood as the non-fixed end of the guide plate or the liquid outlet end of the guide plate, and the liquid flows downward from the suspended end. Among any two adjacent guide plates, the projection of the suspended end of the upper guide plate on the horizontal plane falls on the projection of the lower guide plate on the horizontal plane. In this way, after the liquid flows downward along the upper guide plate, it can fall down to the lower guide plate, so that the liquid can flow through multiple guide plates in sequence without falling directly to the bottom, thereby avoiding the generation of foam.

[0046] See also Figure 1The diagram shows a deflector assembly 23. The deflector assembly 23 comprises multiple deflectors, including one or more first deflectors 231 and one or more second deflectors 232. The first deflectors 231 extend gradually downwardly from the partition 221 toward the sidewall of the second trough 21, while the second deflectors 232 extend gradually downwardly from the sidewall of the second trough 21 toward the partition 221. The first deflectors 231 and second deflectors 232 are alternately arranged vertically. In this way, liquid overflowing from the main chamber 2a is continuously guided by multiple sets of first deflectors 231 and second deflectors 232, and can slowly enter the bottom first chamber 2b. Specifically, one end of the first guide plate 231 is fixed to the partition 221, and the other end is a certain distance from the side wall of the second trough body 21. One end of the second guide plate 232 is fixed to the side wall of the second trough body 21 and is a certain distance from the partition 221. This allows liquid overflowing from the main chamber 2a into the second chamber 2c to be continuously guided along the first guide plate 231 and the second guide plate 232, preventing the liquid from directly falling into the first chamber 2b below and generating foam. Here, of all the guide plates, the first guide plate 231 is located at the top, and the second guide plate 232 is located at the bottom. When setting, the top first guide plate 231 should be located below the through hole 241 with a small height difference.

[0047] See also Figure 6 Another deflector assembly 23 is shown, comprising a first deflector 231, a second deflector 232, and a third deflector 233. The first deflector 231 extends gradually downwardly from the partition 221 toward the sidewall of the second trough 21, the second deflector 232 extends gradually downwardly from the sidewall of the second trough 21 toward the partition 221, and the third deflector 233 extends horizontally. At least one set of the first deflector 231 and the third deflector 233 are provided, alternating between them. The second deflector 232, located at the bottom, ultimately directs the liquid into the first chamber 2b. This also ensures that the liquid undergoes multiple diversions and buffering processes from the liquid outlet to the first chamber 2b, reducing or preventing the formation of foam.

[0048] See also Figure 7Another guide plate assembly 23 is shown, which includes a first guide plate 231, a second guide plate 232, and a third guide plate 233. The first guide plate 231 extends gradually downward from the partition 221 toward the side wall of the second trough body 21, the second guide plate 232 extends gradually downward from the side wall of the second trough body 21 toward the partition 221, and the third guide plate 233 extends horizontally. The first guide plate 231, the second guide plate 232, and the third guide plate 233 are arranged alternately, wherein the second guide plate 232 is located at the top, at least part of which is located below the liquid outlet; the second guide plate 232 is also located at the bottom, which ultimately guides the liquid into the first chamber 2b. The guide plate assembly 23 also allows the liquid to undergo multiple diversions and buffering processes from the liquid outlet to the first chamber 2b, reducing or avoiding the generation of foam.

[0049] See also Figure 8 Another deflector assembly 23 is shown, comprising only a plurality of third deflectors 233 extending horizontally. Of two adjacent third deflectors 233, one third deflector 233 has one end mounted on the partition 221 and the other end spaced apart from the sidewall of the second tank body 21. The other third deflector 233 has one end fixed to the sidewall of the second tank body 21 and the other end spaced apart from the partition 221. The sequential flow diversion of these multiple third deflectors 233 also ensures that the liquid undergoes multiple diversions and buffering processes as it travels from the liquid outlet to the first chamber 2b, reducing or preventing the formation of foam.

[0050] See also Figure 1 、 Figure 3 As shown, in the chemical treatment tank provided in this embodiment, a regulating valve 4 is further provided on the return pipe 3 for regulating the liquid flow in the return pipe 3. By adjusting the regulating valve 4, the flow rate of the liquid returning from the second treatment tank 2 to the first treatment tank 1 can be adjusted, thereby controlling the liquid level in the first chamber 2b within a preset range. When the chemical treatment tank is in operation, the lower portion of the lowest guide plate is suspended above the bottom wall of the first chamber 2b and is located below the liquid level in the first chamber 2b. This allows the liquid to merge seamlessly into the liquid in the first chamber 2b, preventing impact and foaming.

[0051] See also Figure 4 、 Figure 5As shown, the second treatment tank 2 also includes a plurality of drain ports provided on the bottom plate 222 for draining the liquid in the main chamber 2a to facilitate replacement of the liquid or maintenance of the second treatment tank 2. An adjustment plate 26 for adjusting the diameter of the drain port is provided at the drain port to select opening or closing the drain port as required, or to adjust the flow rate / flow rate of the drain through the drain port; a drain pipe 27 is provided at the lower part of the drain port, the diameter of the drain pipe 27 is smaller than the diameter of the drain port, and the drain pipe 27 is located in the first chamber 2b. During the discharge process, the liquid reaches the drain pipe of small diameter from the large-diameter drain port, which can keep the drain pipe filled with liquid, so that the liquid will not enter the drain pipe 27 in a manner with a height difference, thereby avoiding the generation of foam during the discharge process.

[0052] Although not shown in the figure, this embodiment also provides a cell processing device, which uses the chemical treatment tank as described above to process the cell. The processing device can be a cell electroplating device or an etching device.

[0053] In summary, in the chemical treatment tank of this embodiment, a baffle assembly is arranged in the first tank cavity 1a of the first treatment tank 1, and a liquid flow path is formed between the reflux port and the liquid extraction port, so that the liquid can flow along the liquid flow path from the reflux port into the first tank cavity 1a to the liquid flowing out of the first tank cavity 1a from the liquid extraction port, thereby making the liquid flow in the first tank cavity 1a relatively smooth, thereby avoiding or reducing the generation of foam in the first tank cavity 1a, and the liquid contains less foam or even no foam when it is circulated to the main chamber 2a for use, thereby solving the foam problem from the root, so that there is no need to use a foam breaker or add a defoaming agent to eliminate the foam, saving the cost of using a foam breaker or adding a defoaming agent.
