Description

Technical Field

[0001] This utility model relates to the technical field of surface treatment equipment for rolled copper foil, and in particular to a test device for a liquid preparation system for surface treatment of rolled copper foil. Background Technology

[0002] Rolled copper foil is produced from copper ingots through complex processes such as hot rolling, cold rolling, and annealing, possessing excellent ductility, bending resistance, and conductivity. Rolled copper foil is commonly used in flexible copper-clad laminates, mobile phone back panels, and camera modules. Depending on the application, different surface electroplating treatments are required for the rolled copper foil, such as roughening, curing, blackening, zinc plating, and nickel plating. The surface treatment workshop has multiple electroplating tanks, allowing for the sequential electroplating of different layers onto the copper foil surface to obtain products that meet market demands. The solutions in each electroplating tank need to meet requirements of continuous circulation, filtration, constant temperature, and stable solution parameters. This necessitates an auxiliary workshop—the solution preparation workshop—within the surface treatment workshop. The solution preparation workshop occupies a large area and has complex piping, with each solution tank connected to the surface treatment workshop via long pipelines.

[0003] The applications of rolled copper foil are becoming increasingly diverse, leading to higher and more numerous requirements for its surface treatment. This necessitates continuous innovation and experimentation in surface treatment, requiring constant small-scale trials for process adjustments between the laboratory and production lines. However, existing solution preparation workshops are typically equipped with only enough solution tanks for production use due to cost and space constraints. These tanks must be emptied before production trials. Furthermore, the large size of these tanks (approximately 10m in diameter) and the need for the solution tanks to reach a certain level before the processing machine can begin adding solutions, coupled with the solution in the piping and filtration systems, necessitate the preparation of large quantities of solution for testing, resulting in wasted time and resources. Therefore, there is an urgent need to develop a highly efficient, energy-saving, and portable solution preparation system testing device for rolled copper foil surface treatment to meet the requirements of production trials.

[0049] Figure 1 This is a schematic structural diagram of a test apparatus 100 for a liquid preparation system for surface treatment of rolled copper foil according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 4 This utility model provides a test device 100 for a liquid preparation system for surface treatment of rolled copper foil, including a tank 110, a cover plate 130, a stirring device 140, a temperature control heating device 150, and a draining device 160.

[0050] A tank 110 has a top-opening receiving cavity 111 inside, and the tank 110 is mounted on a traveling device 120. A cover plate 130 is disposed at the top opening of the tank 110; the cover plate 130 includes a first part 131 and a second part 132, the second part 132 and the first part 131 being movably connected so that the second part 132 opens or closes a portion of the opening of the receiving cavity 111. A stirring device 140 is mounted on the first part 131, and the stirring part 142 of the stirring device 140 is located inside the receiving cavity 111; a temperature-controlled heating device 150 is mounted on the first part 131 and is used to adjust the temperature of the solution inside the receiving cavity 111. A draining device 160 is mounted on the first part 131 and is used to transport the solution inside the receiving cavity 111 to a processing machine. Specifically, the processing machine refers to an electroplating tank.

[0051] When using the solution preparation system test device 100 of this embodiment, after assembling all parts, a solution can be prepared. First, turn on the stirring device 140 and the temperature control device. When the solution temperature rises to the set temperature, the solution is delivered to the processor through the draining device 160. Then, the surface treatment test is carried out in the processor.

[0052] The experimental apparatus 100 for a surface treatment solution preparation system for rolled copper foil provided in this embodiment of the invention is based on a modular design and flexible operation. The tank 110, serving as the main body for solution storage and processing, is easily movable via a walking device 120 to adapt to different testing scenarios. The cover 130 is divided into two movable parts. Opening the second part 132 allows for easy observation of the state of the solution inside the containment chamber 111 and the working status of each device during the operation of the experimental apparatus, facilitating adjustments to the solution volume, stirring, temperature control, and discharge. The stirring device 140 ensures uniform mixing of the solution, while the temperature control heating device 150 precisely regulates the solution temperature to meet the requirements of different surface treatment processes. The discharge device 160 is responsible for transporting the prepared solution to the processing machine, completing the entire solution preparation process. Through the coordinated operation of its components, the entire solution preparation system experimental apparatus 100 achieves efficient and precise solution preparation.

[0053] In this embodiment, firstly, the solution preparation system test device 100 is small in size and has short pipes; and through the design of the walking device 120, the solution preparation system test device 100 can be moved flexibly, allowing it to be moved next to different processing machines. This avoids the inconvenience caused by the large size and fixed position of traditional solution preparation tanks in the workshop, improving the flexibility and efficiency of the test, reducing solution waste, and saving test costs. Secondly, the movable connection between the first part 131 and the second part 132 of the cover plate 130 makes the operation of solution preparation, stirring, temperature adjustment, and discharge more convenient, which helps to reduce solution waste and test costs. In addition, the precise control of the stirring device 140 and the temperature control heating device 150 ensures the uniformity of the solution and temperature stability, improving the accuracy and reliability of the surface treatment test. Furthermore, the stirring device 140, the temperature control heating device 150, and the draining device 160 are all installed on the first part 131, which facilitates the assembly and disassembly of the liquid preparation system test device 100. Removing the cover plate 130 from the tank body 110 allows for easy maintenance of various components and convenient cleaning of the containing cavity 111, facilitating the preparation of different surface treatment solutions. For example... Figure 4 As shown, in some embodiments of this invention, the second part 132 is rotatably mounted on the first part 131 via a first rotating shaft, which is horizontally positioned. The second part 132 can rotate up and down around the rotating shaft to open or close a partial opening at the top of the can 110. In other embodiments, the second part 132 is mounted on the first part 131 via a second rotating shaft, which is vertically positioned and located at the edge of both the first part 131 and the second part 132. The second part 132 can rotate around the second rotating shaft to open or close a partial opening at the top of the can 110.

[0054] like Figures 1 to 3As shown, in some embodiments of this utility model, the liquid preparation system test device 100 further includes a dosing device 170 and an infusion pipe 181. The dosing device 170 is installed on the first part 131, and the outlet of the dosing device 170 is connected to the receiving cavity 111; the infusion pipe 181 is installed on the first part 131 through the fifth mounting hole 137, the inlet of the infusion pipe 181 is used to connect to the drain port of the processor, and the outlet of the infusion pipe 181 is connected to the receiving cavity 111.

[0055] In this embodiment, during the operation of the solution preparation system test apparatus 100, the walking device 120 first moves the apparatus 100 to a designated position. Then, according to the test requirements, the second part 132 of the cover plate 130 is used to open the opening of the receiving cavity 111, and the required reagents and water are precisely added into the receiving cavity 111. The stirring device 140 is then activated to ensure that the reagents and water are thoroughly and evenly mixed. The temperature control heating device 150 can adjust the solution temperature according to preset parameters to meet specific process requirements. After the solution preparation is completed, the draining device 160 transports the solution to the processing machine.

[0056] When the test time for surface treatment of rolled copper foil is long, the pH and electroplating ion concentration (such as nickel ions, zinc ions, copper ions, or chromium ions) of the solution in the treatment machine are prone to significant changes, leading to inaccurate test results. To avoid this, this embodiment is equipped with a dosing device 170 and a delivery pipe 181. During the test, the delivery pipe 181 transports part of the solution discharged from the treatment machine to the receiving cavity 111, while the dosing device 170 replenishes the solution in the receiving cavity 111. This enables the surface treatment solution to circulate between the solution preparation system test device 100 and the treatment machine, stabilizing the pH and electroplating ion concentration of the surface treatment solution in the treatment machine and improving the accuracy of the test results.

[0057] This embodiment enhances the functionality of the solution preparation system test device 100 by adding a dosing device 170 and a delivery pipe 181, thus meeting a wider range of testing needs for the surface treatment of rolled copper foil. Specifically, the test device in this embodiment is small in size, fully functional, and easy to use, and can meet the requirements of the treatment tank solution for temperature, circulation, stability, and online testing.

[0058] like Figures 2 to 4As shown, in some embodiments of this utility model, the dosing device 170 includes a drug storage section 171 and a dosing tube 172. The drug storage section 171 has an inlet and an outlet, and a valve 173 is provided at the outlet of the drug storage section 171 to control the opening degree of the outlet of the drug storage section 171. A first mounting hole 133 is provided on the first part 131, and the dosing tube 172 is inserted into the first mounting hole 133 and fixedly connected to the first mounting hole 133. The inlet of the dosing tube 172 communicates with the outlet of the drug storage section 171, and the outlet of the dosing tube 172 communicates with the receiving cavity 111. In this embodiment, by setting the valve 173, the opening and closing of the outlet of the drug storage section 171 and the opening degree can be adjusted according to the consumption of electroplating chemicals during the test to control the dosing amount. Wherein, when the minimum opening degree of the valve 173 is zero, the outlet of the drug storage section 171 is closed.

[0059] Furthermore, in some embodiments of this invention, the drug storage portion 171 is conical in shape, wider at the top and narrower at the bottom. In some alternative embodiments, the drug storage portion 171 may also be square or spherical.

[0060] In this embodiment, the drug storage section 171 has a conical design that is larger at the top and smaller at the bottom, which can naturally guide the liquid medicine to the outlet, reduce the accumulation of liquid medicine, improve the efficiency of drug dosing, and at the same time facilitate cleaning and maintenance, ensuring the accuracy and stability of the drug dosing process.

[0061] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the dosing device 170 is a dropping funnel. The drug storage section 171, the valve 173, and the dosing pipe 172 constitute the dropping funnel. The drug is added slowly by dripping through the dropping funnel. Based on the consumption obtained from previous experiments, the dripping amount of the dropping funnel is adjusted to facilitate the stabilization of the pH and electroplating ion concentration of the surface treatment solution.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the liquid preparation system test device 100 further includes a filter section, which is installed at the outlet of the infusion pipe 181. By providing the filter section, the solution discharged from the processor can be filtered.

[0063] Furthermore, in some embodiments of this utility model, the filtration section includes a filter bag 182, which is sleeved on the end of the infusion tube 181 and secured by a rope. In some alternative embodiments, the filtration section may also be a filter screen or a filter plate. Compared with filter screens and filter plates, the filter bag 182 has the advantages of being easy to install and replace, having a large filtration area, and low operating costs.

[0064] Furthermore, in some embodiments of this invention, the filter bag 182 has a multi-layer structure, with the pore size gradually decreasing from the inside to the outside. For example, the pore sizes of the filter bag 182 from the inside to the outside are 10μm, 5μm, and 1μm respectively. This filter bag 182 can filter impurities and precipitates larger than 1μm in the solution. This embodiment can efficiently intercept impurities of different sizes layer by layer, improving filtration accuracy and efficiency, while extending the service life of the filter bag 182 and ensuring a purer fluid after filtration.

[0065] like Figure 2 and Figure 3 As shown, in some optional embodiments of this utility model, the temperature-controlled heating device 150 includes a heating element 151, a temperature sensor 152, and a temperature control switch 153. The heating element 151 is located inside the receiving cavity 111 and is used to heat the solution inside the receiving cavity 111. The temperature sensor 152 is disposed inside the receiving cavity 111 and is used to detect the temperature of the solution inside the receiving cavity 111. The temperature control switch 153 is disposed outside the receiving cavity 111 and is used to control the opening and closing of the heating element or adjust the power of the heating element according to the signal from the temperature sensor 152, so that the temperature of the solution inside the receiving cavity 111 reaches or approaches a set temperature, for example, the set temperature can be 30°C.

[0066] Specifically, the heating element is located in the center of the receiving cavity 111, and the temperature sensor 152 is located at the edge of the receiving cavity 111. A third mounting hole 135 for inserting the mounting part 154 is provided on the first part 131 of the cover plate 130 via the mounting part 154. The mounting part 154 includes a housing and connecting wires. The housing is made of rigid material. The heating element, temperature sensor 152, and temperature control switch 153 are mounted on the mounting part 154, and the heating element and temperature control switch 153, as well as the temperature sensor 152 and temperature control switch 153, are electrically connected via connecting wires.

The stirring shaft 141 is rotatably mounted on the first part 131, and the stirring part 142 is disposed on the outer wall of the stirring shaft 141. The output shaft of the motor 143 is fixedly connected to the stirring shaft 141 and is used to drive the stirring shaft 141 to rotate.

[0068] Specifically, the first part 131 is provided with a fourth mounting hole 136, and the stirring shaft 141 is inserted into the fourth mounting hole 136. The stirring shaft 141 extends in the vertical direction, and the stirring parts 142 are arranged vertically or inclinedly relative to the stirring shaft 141. There are multiple stirring parts 142, which are spaced apart on the outer wall of the stirring shaft 141. The motor is located above the cover plate 130. When the stirring device 140 is working, the motor 143 drives the stirring shaft 141 to rotate, thereby driving the stirring parts 142 to rotate, so as to stir the solution. This stirring device 140 has the advantages of simple structure, simple operation, and easy manufacturing and assembly.

[0069] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the draining device 160 includes a drain pipe 161 and a drain pump 162. A second mounting hole 134 is provided on the first part 131, and the drain pipe 161 is inserted into the second mounting hole 134. The inlet of the drain pipe 161 is located at the lower part of the receiving cavity 111, and the outlet of the drain pipe 161 communicates with the interior of the processor. The drain pump 162 is disposed on the drain pipe 161 and is used to drain the solution in the receiving cavity 111. The drain pump 162 can be disposed at the inlet of the drain pipe 161, or at the outlet or in the middle of the drain pipe 161. By providing the drain pump 162, the draining efficiency can be improved.

[0071] This embodiment achieves effective filtration and separation of liquid by designing a receiving cavity 111 containing a first cavity 1111 and a second cavity 1112, and setting a filter screen 190 between the two cavities. The connection between the drain device 160 and the second cavity 1112 facilitates the discharge of the filtered liquid, preventing sediment or impurities from being discharged into the processing machine and affecting the test results of surface treatment.

[0075] Furthermore, the limiting structure 122 is distributed around the outer periphery of the tank 110 to prevent the tank 110 from shaking during movement, thereby improving the overall safety and reliability of the test device.

[0076] In some embodiments of this utility model, the limiting structure 122 includes multiple limiting plates, which are evenly arranged along the outer periphery of the tank body 110.

[0077] Preferably, the limiting plate is an elastic plate. When the limiting plate is in its initial state, it is curved and bends toward the center of the base 121.
