Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a copper cylinder conductive cooling water tank device. Background Technology

[0002] In the VCP electroplating process, a large amount of direct current needs to be transmitted to a continuously moving substrate (such as a PCB board) through a conductive mechanism to complete electrochemical deposition in the plating tank. During this process, when a large current passes through the sliding contact area between the conductive contacts and the conductive unit (such as a copper slider or roller), a large amount of Joule heat is generated due to the contact resistance, causing the temperature of that area to rise sharply. The high temperature not only accelerates the oxidation of copper materials, forming an oxide layer with higher resistance, resulting in energy waste and instability in the electroplating process, but may also trigger equipment overheating alarms or even shutdowns, seriously affecting production efficiency and product yield.

[0003] To address the aforementioned overheating issue, current technologies generally employ a cooling water tank external to the conductive mechanism, using circulating cooling water to cool the mechanism. However, most current cooling water tanks are long, integrally welded structures. VCP electroplating lines are often tens of meters long, resulting in enormous cooling water tanks. This integral structure presents several drawbacks: First, its manufacturing, transportation, and installation in cleanrooms are extremely difficult and costly; second, if any part of the tank is damaged or leaks, repair and replacement are very inconvenient, requiring a complete shutdown; finally, to ensure a consistent liquid level throughout the long tank, an overflow port at a fixed height is typically installed at one end, making precise control and adjustment of the liquid level difficult. An excessively high liquid level can lead to cooling water overflow and environmental pollution, while an excessively low liquid level may result in insufficient cooling of some conductive contacts, uneven cooling, and compromised conductivity stability.

[0004] Therefore, the existing copper cylinder conductive cooling water tank device has defects such as poor portability, low maintainability and insufficient liquid level control accuracy, and a new structural solution is urgently needed to solve these problems. Utility Model Content

[0005] Therefore, it is necessary to provide a copper cylinder conductive cooling water tank device to address the technical problems of poor portability and insufficient liquid level control accuracy of existing cooling water tanks.

[0006] A copper cylinder conductive cooling water tank device is disclosed, comprising a cooling water tank and a conductive mechanism, wherein the conductive mechanism is installed in the cooling water tank.

[0007] The cooling water tank includes a connecting tank and a drain tank. Several connecting tanks can be arranged in sequence and connected end to end to form a main tank structure with leak-proof performance. The drain tank is set at both ends of the main tank structure to form a complete cooling water tank.

[0008] One end of the drainage trough is connected to the adjacent connecting trough, and the other end of the drainage trough is provided with a drain outlet, a temporary water storage tank and a weir plate; the drain outlet is located on the end wall of the corresponding end of the drainage trough; the temporary water storage tank is a box structure that extends outward from the end wall of the drainage trough, and the temporary water storage tank is connected to the inside of the drainage trough through the drain outlet; the weir plate is fitted to the drain outlet and is movably connected to the end wall of the drainage trough.

[0009] In one embodiment, the aforementioned temporary water tank is provided with a drain pipe located at the bottom of the temporary water tank.

[0010] In one embodiment, the drainage trough body is provided with a matching groove on one end wall of the connecting weir plate, and the weir plate is movably fitted into the matching groove.

[0011] In one embodiment, the aforementioned weir plate and the groove wall of the mating groove are connected by an interference fit.

[0012] In one embodiment, the aforementioned weir plate is made of an elastic material.

[0013] In one embodiment, the cooling water tank is provided with a plurality of connectors, which are respectively disposed on the bottom wall of each connecting tank and each drain tank. The two connecting tanks and the connecting tank and the drain tank are connected by corresponding connectors.

[0014] In one embodiment, the two ends of the connecting groove are provided with sealing elements. The sealing elements are provided at the corresponding end faces of the connecting groove. When the two connecting grooves are connected or the connecting groove is connected to the drainage groove, the sealing elements fill the connection between the connecting groove and the adjacent connecting groove or drainage groove.

[0015] In one embodiment, the aforementioned seal is configured as an elastic sealing strip.

[0016] In one embodiment, the aforementioned connecting groove is provided with a first splash guard, which is located on the top of one side wall of the connecting groove and extends a predetermined distance to the opposite side.

[0017] In one embodiment, the drainage trough is provided with a second splash guard, which is located on the top of one side wall of the drainage trough and extends a predetermined distance to the opposite side.

[0018] In one embodiment, the aforementioned conductive mechanism comprises a conductive copper busbar and several copper conductive brush heads.

[0019] The aforementioned copper cylinder conductive cooling water tank device is composed of connecting tanks and drainage tanks. Users can flexibly configure the number of tanks according to the actual space of the production workshop and the length of the electroplating line, thereby extending or shortening the production line. When a section of the connecting tank is damaged or needs cleaning, only that section can be operated on, without having to empty and deal with the entire giant tank, greatly reducing maintenance difficulty and downtime. Furthermore, the height of the drain outlet can be adjusted by the movable weir plate to form an overflow structure to control the liquid level, allowing operators to precisely set the optimal liquid level height to adapt to different process formulas and optimize production results. In addition, the overflowing water enters the temporary storage tank and can be either refilled or discharged. The temporary storage tank can serve as an auxiliary heat dissipation pool, which helps stabilize the water temperature. If necessary, the water that has risen in temperature can be directly drained and replaced with new, cool water, thereby controlling the temperature of the entire cooling system more efficiently.

[0027] Please see Figures 1 to 5This utility model discloses a copper cylinder conductive cooling water tank 10 device 1, which includes a cooling water tank 10 and a conductive mechanism 20. The conductive mechanism 20 is installed in the cooling water tank 10, so that in the actual electroplating process, the cooling water tank 10, in combination with circulating cooling water, can cool and reduce the temperature of the conductive mechanism 20, thereby ensuring the conductivity of the conductive mechanism 20. The cooling water tank 10 includes a connecting tank body 11 and a drain tank body 12. Several connecting tank bodies 11 can be arranged in sequence and connected end to end to form a main tank structure with leak-proof performance. The drain tank body 12 is set at both ends of the main tank structure to form a complete cooling water tank 10. This realizes the multi-segment connection structure of the cooling water tank 10, thereby greatly enhancing the portability of the cooling water tank 10, making the cooling water tank 10 easy to transport and easy to assemble. In the actual electroplating production, the end of the drain tank body 12 can be used for overall control of the cooling water level of the cooling water tank 10 and for filling and draining the cooling water. Specifically, one end of the drainage trough 12 is connected to the adjacent connecting trough 11, and the other end of the drainage trough 12 is provided with a drain outlet a, a temporary storage tank 121, and a weir plate 122. The drain outlet a is located on the end wall of the corresponding end of the drainage trough 12. The temporary storage tank 121 is a box structure that extends outward from the end wall of the drainage trough 12, and the temporary storage tank 121 is connected to the interior of the drainage trough 12 through the drain outlet a. The weir plate 122 is fitted to the drain outlet a and is movably connected to the end wall of the drainage trough 12. Thus, by adjusting the relative height between the weir plate 122 and the drainage trough 12, the drainage height of the drain outlet a can be adjusted, thereby forming an overflow structure, controlling the liquid level inside the drainage trough 12, and the overflowing cooling water flows into the temporary storage tank 121 for temporary storage. The cooling water can be returned to the drainage trough 12 according to the actual cooling needs, or directly discharged to the outside of the cooling water tank 10. Based on the above configuration, the copper cylinder conductive cooling water tank 10 device 1 of this solution is composed of a connecting tank 11 and a drainage tank 12 connected together. Users can flexibly configure the number of tanks according to the actual space of the production workshop and the length of the electroplating line to extend or shorten the production line. When a section of the connecting tank 11 is damaged or needs cleaning, only that section can be operated on without emptying and treating the entire giant tank, which greatly reduces maintenance difficulty and downtime. Furthermore, the height of the drain outlet a can be adjusted by the movable weir plate 122 to form an overflow structure to control the liquid level, allowing operators to accurately set the optimal liquid level height to adapt to different process formulas and optimize production results. In addition, the overflowing water enters the temporary storage tank 121 and can be either refilled or discharged. The temporary storage tank 121 can serve as an auxiliary heat dissipation pool, which helps stabilize the water temperature. If necessary, the water with the increased temperature can be directly drained and replaced with new water at a lower temperature, thereby controlling the temperature of the entire cooling system more efficiently.

[0028] Furthermore, the temporary water tank 121 is provided with a drain pipe 1211, which is located at the bottom of the temporary water tank 121 for discharging the cooling water inside the temporary water tank 121.

[0029] Furthermore, a matching groove b is provided on one end wall of the drainage trough 12 body connected to the weir plate 122. The weir plate 122 is movably fitted into the matching groove b, so that the operator can adjust the relative height of the weir plate 122 to the drainage trough 12 body to control the drainage height of the drainage outlet a.

[0030] Specifically, in one embodiment, the weir plate 122 and the wall of the mating groove b are connected by an interference fit to ensure the tightness of the connection between the weir plate 122 and the mating groove b, thereby ensuring the sealing performance of the weir plate 122 to the drain outlet a. In another embodiment, the weir plate 122 is made of an elastic material, so that by controlling the thickness of the weir plate 122, an elastic connection between the weir plate 122 and the wall of the mating groove b can be achieved, thereby further enhancing the sealing performance between the weir plate 122 and the drain outlet a based on the rebound capability of the weir plate 122 itself.

[0031] Furthermore, the cooling water tank 10 is provided with a number of connectors 13, which are respectively provided on the bottom wall of each connecting tank 11 and each drain tank 12. The two connecting tanks 11 and the connecting tank 11 and the drain tank 12 are connected by corresponding connectors 13 to form the overall structure of the cooling water tank 10.

[0032] Furthermore, sealing elements 111 are provided at both ends of the connecting groove 11. The sealing elements 111 are located at the corresponding end faces of the connecting groove 11. When the two connecting grooves 11 are connected or the connecting groove 11 is connected to the drainage groove 12, the sealing elements 111 fill the connection between the connecting groove 11 and the adjacent connecting groove 11 and drainage groove 12 to ensure the sealing performance between adjacent grooves.

[0033] Specifically, in one embodiment, the seal 111 is set as an elastic sealing strip to ensure the overall leak-proof capability of the cooling water tank 10, prevent cooling water from leaking between the joints of each tank unit, and thus maintain the stability of the cooling water level in the tank.

[0034] Furthermore, the connecting tank 11 is provided with a first splash guard 112. The first splash guard 112 is located on the top of one side wall of the connecting tank 11 and extends a predetermined distance to the opposite side, thereby forming a splash guard structure that shields the top side of the open opening of the connecting tank 11, so as to avoid excessive consumption of cooling water due to splashing during the electroplating process.

[0035] Correspondingly, the drainage trough 12 body is provided with a second splash guard 123. The second splash guard 123 is located on the top of one side wall of the drainage trough 12 body and extends to the opposite side by a predetermined distance, thereby forming a splash guard structure that shields the top side of the open opening of the drainage trough 12 body, so as to realize the splash guard function of the drainage trough 12 body.

[0036] Furthermore, the conductive mechanism 20 consists of a conductive copper busbar and several copper conductive brush heads, which are installed and housed inside several connecting grooves 11 and drainage grooves 12 at both ends. The specific arrangement is a conventional method in the art and will not be described in detail here.

[0037] In summary, the copper cylinder conductive cooling water tank device disclosed in this utility model is composed of a connecting tank and a drainage tank connected together. Users can flexibly configure the number of tanks according to the actual space of the production workshop and the length of the electroplating line to extend or shorten the production line. When a section of the connecting tank is damaged or needs cleaning, only that section can be operated on, without having to empty and deal with the entire giant tank, greatly reducing maintenance difficulty and downtime. Furthermore, the height of the drain outlet can be adjusted by the movable weir plate to form an overflow structure to control the liquid level, allowing operators to accurately set the optimal liquid level height to adapt to different process formulas and optimize production results. In addition, the overflowing water enters a temporary storage tank and can be either refilled or discharged. The temporary storage tank can serve as an auxiliary heat dissipation pool, which helps stabilize the water temperature. If necessary, the water that has risen in temperature can be directly drained and replaced with new, cool water, thereby controlling the temperature of the entire cooling system more efficiently.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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 patent should be determined by the appended claims.
