DETAILED DESCRIPTION

[0035] 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.

[0036] See also Figures 1 to 5 A chemical treatment tank shown includes at least a first treatment tank 1, which includes a first tank body 11 having a first tank cavity. The first tank cavity includes a main chamber 1a and a first chamber 1c. The main chamber 1a has a liquid outlet, and the first chamber 1c is located below the liquid outlet.

[0037] When the product to be processed is chemically treated, the main chamber 1a is filled with liquid for chemical treatment, and the product to be processed is transferred or placed in the main chamber 1a to contact the liquid for chemical treatment. For example, when the battery cell is electroplated, the main chamber 1a is filled with electroplating liquid, and the battery cell is electroplated when it contacts the electroplating liquid in the main chamber 1a. In some embodiments, the product to be processed can be translated in the main chamber 1a along the length extension direction of the first trough body 11. During processing, the product to be processed is transferred to the main chamber 1a along the length extension direction of the first trough body 11 by a transmission mechanism and is contacted with the liquid for processing. After completion, the product is transferred out of the main chamber 1a by the transmission mechanism. When there is too much liquid in the main chamber 1a, the excess liquid flows from the liquid outlet into the first chamber 1c for easy recycling.

[0038] In the chemical treatment tank, the first treatment tank 1 also includes a guide plate assembly 13 for buffering the liquid flowing out of the liquid outlet and then introducing it into the first chamber 1c. The guide plate assembly 13 includes a plurality of guide plates sequentially distributed in 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 1c after multiple buffering. In this way, when the chemical treatment tank is working, after the liquid in the main chamber 1a flows out from the liquid outlet, the liquid will pass through the multiple guide plates of the guide plate assembly 13, and then enter the first chamber 1c after multiple buffering from top to bottom. This makes the drop of the liquid from top to bottom in the process of flowing to the first chamber 1c smaller, which can avoid or reduce the generation of foam as much as possible. The liquid entering the first chamber 1c contains less foam or even no foam when it is returned to the main chamber 1a for use, thus reducing or eliminating the generation of foam from the root, so there is no need to use a foam breaker or add a defoaming agent to eliminate foam.

[0039] In the chemical treatment tank provided in this embodiment, the first tank cavity also includes a second chamber 1b located on at least one side of the main chamber 1a. The upper part of the second chamber 1b is connected to the main chamber 1a through the liquid outlet. The first chamber 1c is located below the second chamber 1b and is connected to the second chamber 1b. After the liquid in the main chamber 1a flows out from the liquid outlet, it first enters the second chamber 1b and then flows downward into the first chamber 1c.

[0040] An overflow plate 14 is disposed between the main chamber 1a and the second chamber 1b. This plate is provided with multiple through-holes 141 extending through its thickness. These through-holes 141 establish fluid communication between the second chamber 1b and the main chamber 1a. These through-holes 141 serve as the aforementioned liquid outlets. Liquid in the main chamber 1a flows through these through-holes 141 into the second chamber 1b, resulting in a more gradual flow rate when the liquid enters the second chamber 1b, further reducing or preventing the formation of foam.

[0041] The second chamber 1b is located on one or both sides of the main chamber 1a in the direction of the width of the first trough 11. When there are two second chambers 1b, they are spaced apart in the direction of the width of the first trough 11, and each second chamber 1b is connected to the main chamber 1a at its upper portion. When there is only one second chamber 1b, the second chamber 1b is located side by side with the main chamber 1a. When there is too much liquid in the main chamber 1a, the excess liquid can flow from the upper portion of the second chamber 1b into the second chamber 1b, and then flow into the first chamber 1c.

[0042] The first treatment tank 1 also includes a partition assembly 12, by which the first tank cavity is divided into a main chamber 1a, a second chamber 1b, and a first chamber 1c. The partition assembly 12 includes at least one partition 121 and a bottom plate 122. The partition 121 is vertically arranged in the first tank body 11 and has a certain distance from the side wall of the first tank body 11 to form the second chamber 1b; the bottom plate 122 is horizontally arranged in the first tank body 11 and is connected to the partition 121 and the first tank body 11 on both sides, or is connected to two partitions 121 respectively. The bottom plate 122 has a certain distance from the bottom of the first tank body 11 to vertically divide the first tank body 11 into the main chamber 1a and the first chamber 1c. In this embodiment, there are two second chambers 1b arranged on both sides of the main chamber 1a. Each second chamber 1b is formed between the two vertical partitions 121 and the two side walls of the first tank body 11, and the bottom plate 122 is connected between the two partitions 121.

[0043] As shown in the accompanying drawings, the guide plate assembly 13 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 1b. Specifically, in some embodiments, all guide plates are located in the second chamber 1b; in other embodiments, the guide plate located at the top extends into the main chamber 1a to guide the liquid in the main chamber 1a 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 1c; in some other embodiments, guide plates are provided in both the first chamber 1c and the second chamber 1b. This allows the liquid to be guided and buffered during its passage through the second chamber 1b, reducing the generation of foam. Among the multiple guide plates of the guide plate assembly 13, 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.

[0044] See also Figure 1The device provides a deflector assembly 13. The deflector assembly 13 comprises multiple deflectors, including one or more first deflectors 131 and one or more second deflectors 132. The first deflectors 131 extend gradually downwardly from the partition 121 toward the sidewall of the first trough 11, while the second deflectors 132 extend gradually downwardly from the sidewall of the first trough 11 toward the partition 121. The first deflectors 131 and second deflectors 132 are alternately arranged vertically. This allows liquid overflowing from the main chamber 1a to flow through the multiple sets of first deflectors 131 and second deflectors 132, allowing it to slowly enter the bottom first chamber 1c. Specifically, one end of the first guide plate 131 is fixed to the partition 121, and the other end is a certain distance from the side wall of the first trough body 11. One end of the second guide plate 132 is fixed to the side wall of the first trough body 11 and is a certain distance from the partition 121. This allows liquid overflowing from the main chamber 1a into the second chamber 1b to be continuously guided along the first guide plate 131 and the second guide plate 132, preventing the liquid from directly falling into the first chamber 1c below and generating foam. Here, among all the guide plates, the first guide plate 131 is located at the top, and the second guide plate 132 is located at the bottom. When setting, the first guide plate 131, located at the top, should be located below the through hole 141 with a small height difference.

[0045] See also Figure 6 Another guide plate assembly 13 is shown, comprising a first guide plate 131, a second guide plate 132, and a third guide plate 133. The first guide plate 131 extends gradually downwardly from the partition 121 toward the sidewall of the first trough body 11, the second guide plate 132 extends gradually downwardly from the sidewall of the first trough body 11 toward the partition 121, and the third guide plate 133 extends horizontally. There are at least one set of first guide plates 131 and third guide plates 133, and the two are arranged alternately. The second guide plate 132 is located at the bottom and ultimately guides the liquid into the first chamber 1c. This also allows the liquid to undergo multiple diversions and buffering processes from the liquid outlet to the first chamber 1c, reducing or preventing the generation of foam.

[0046] See also Figure 7Another guide plate assembly 13 is shown, which includes a first guide plate 131, a second guide plate 132, and a third guide plate 133. The first guide plate 131 extends gradually downward from the partition 121 toward the side wall of the first trough body 11; the second guide plate 132 extends gradually downward from the side wall of the first trough body 11 toward the partition 121; and the third guide plate 133 extends horizontally. The first guide plate 131, the second guide plate 132, and the third guide plate 133 are arranged alternately, wherein the second guide plate 132 is located at the top, at least part of which is located below the liquid outlet; the second guide plate 132 is also located at the bottom, which finally guides the liquid into the first chamber 1c. The guide plate assembly 13 also allows the liquid to undergo multiple diversions and buffering processes from the liquid outlet to the first chamber 1c, reducing or avoiding the generation of foam.

[0047] See also Figure 8 Another deflector assembly 13 is shown, comprising only a plurality of third deflectors 133 extending horizontally. Of two adjacent third deflectors 133, one third deflector 133 has one end mounted on the partition 121 and the other end spaced apart from the sidewall of the first tank body 11. The other third deflector 133 has one end fixed to the sidewall of the first tank body 11 and the other end spaced apart from the partition 121. The sequential flow diversion of these multiple third deflectors 133 also ensures that the liquid undergoes multiple diversions and buffering processes from the liquid outlet to the first chamber 1c, reducing or preventing the generation of foam.

[0048] As shown in the accompanying drawings, the bottom of the first chamber 1c is provided with a drain port 15 connected thereto, and the liquid collected in the first chamber 1c is discharged outward through the drain port 15; the bottom of the main chamber 1a is also provided with a liquid supply port (not shown in the drawings) for supplying liquid into the main chamber 1a.

[0049] The chemical treatment tank also includes a second treatment tank 2, which includes a second tank body 21 having a second tank cavity 2a, and the second tank body 21 is provided with a reflux port (not shown in the figure) and a liquid extraction port (not shown in the figure) respectively connected to the second tank cavity 2a. In some embodiments, the liquid discharge port 15 is higher than the above-mentioned reflux port in the vertical direction, and the liquid discharge port 15 is connected to the reflux port through a reflux pipe 3, and the liquid extraction port is connected to the liquid supply port through a liquid supply pipe (not shown in the figure). In this way, the liquid overflows from the main chamber 1a of the first treatment tank 1 to the second chamber 1b and then reaches the first chamber 1c, and then enters the second tank cavity 2a of the second treatment tank 2 through the liquid discharge port 15, the reflux pipe 3 and the reflux port, and then circulates from the liquid extraction port through the liquid supply pipe and the liquid supply port to the main chamber 1a under the action of the pumping device.

[0050] See also Figure 3As shown, the second treatment tank 2 also includes a baffle assembly disposed within the second tank cavity 2a. The baffle assembly includes a plurality of baffles 22 spaced apart along a first direction. All of the baffles 22 extend along a second direction. All of the baffles 22 cooperate to form a liquid flow path for liquid to flow from the reflux port to the liquid extraction port. This allows the liquid flow in the second tank cavity 2a to be relatively stable, further avoiding or reducing the generation of foam. The first direction and the second direction intersect and are specifically perpendicular to each other, which can specifically be the length and width directions of the second treatment tank 2.

[0051] 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 second groove cavity 2a; one group of liquid extraction ports is provided, and the liquid extraction port is provided between the two groups of reflux ports, and a liquid flow path as mentioned above is formed between each reflux port and the liquid extraction port.

[0052] In this embodiment, the chemical treatment tank further includes a liquid extraction pipe 5 extending in the second direction and located within the second tank cavity 2a. 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 the 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 second tank cavity 2a through the reflux ports at both ends. Subsequently, under the guidance of the plurality of baffles 22, 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 1a through the liquid extraction pipe.

[0053] When configuring the second treatment tank 2, one end of each baffle 22 abuts against one side wall of the second tank body 21, while the other end maintains a certain distance from the other side wall of the second tank body 21, thereby restricting liquid flow to a predetermined direction. Furthermore, the height of each baffle 22 should be higher than the liquid level during operation of the second treatment tank 2. The bottom wall 211 of the second tank chamber 2a extends obliquely to one side to facilitate drainage of the liquid within the second tank chamber 2a.

[0054] The return pipe 3 is also equipped with a regulating valve 4 for adjusting the liquid flow rate in the return pipe 3. By adjusting the regulating valve 4, the liquid flow rate when returning from the first treatment tank 1 to the second treatment tank 2 can be adjusted, thereby controlling the liquid level in the first chamber 1c within a preset range. When the chemical treatment tank is in operation, the lower portion of the bottommost guide plate is suspended above the bottom wall of the first chamber 1c and is located below the liquid level in the first chamber 1c. This allows the liquid to flow smoothly into the liquid in the first chamber 1c, preventing impact and foaming.

[0055] See also Figure 4 、 Figure 5 As shown, the first treatment tank 1 also includes a plurality of drain ports provided on the bottom plate 122 for draining the liquid in the main chamber 1a, thereby facilitating the replacement of the liquid or maintenance of the first treatment tank 1. An adjustment plate 16 for adjusting the diameter of the drain port is provided at the drain port, so as to select to open or close the drain port as needed, or to adjust the flow rate / flow rate of the discharge through the drain port; a drain pipe 17 is provided at the lower part of the drain port, the diameter of the drain pipe 17 is smaller than the diameter of the drain port, and the drain pipe 17 is located in the first chamber 1c. During the discharge process, the liquid reaches the drain pipe with a 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 17 in a manner with a height difference, thereby avoiding the generation of foam during the discharge process.

[0056] 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.

[0057] In summary, the chemical treatment tank of this embodiment is provided with a guide plate assembly 13, so that the liquid flowing out of the main chamber 1a can be buffered and enter the first chamber 1c, so that there is basically no impact during the downward process of the liquid, thereby solving the foam problem from the root. In this way, 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.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly.
