Abstract
Description

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous layer of metal foil deposited on the substrate of the circuit board. It serves as the conductor of the PCB. It easily adheres to the insulating layer, accepts the printed protective layer, and forms the circuit pattern after corrosion.
[0003] During the copper foil production process, the foil is moved along by conductive rollers through processes such as pickling, roughening, curing, and washing. After pickling, the copper foil enters the roughening and curing processes, and copper sulfate solution is deposited on its surface. This solution then adheres to the conductive rollers, potentially causing copper plating on the conductive rollers.
[0004] In order to solve the problem of copper plating on the conductive roller, a spray pipe is currently used to spray the conductive roller. However, the liquid after spraying the conductive roller is easily discharged together with the pickling liquid and other liquids, which increases the cost of wastewater treatment.

[0037] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted.

[0038] Example 1
[0039] When the copper foil comes out of the roughening tank or the curing tank, a large amount of copper sulfate solution will be attached to its surface. When the copper foil moves under the drive of the conductive roller 200, the copper sulfate solution attached to the surface of the copper foil will adhere to the conductive roller 200, which can easily cause copper plating on the surface of the conductive roller 200.
[0040] In order to solve the problem that the copper sulfate solution adheres to the conductive roller 200 and causes the conductive roller 200 to be copper-plated, the first embodiment of the present application provides a cleaning module 100. This cleaning module 100 is used to clean the conductive roller 200 to remove the copper sulfate solution remaining on the conductive roller 200 when transporting copper foil, thereby preventing the conductive roller 200 from being copper-plated. The cleaning liquid used to clean the conductive roller 200 can also be discharged separately to reduce wastewater treatment costs.
[0041] In the examples of this application, see Figure 1 As shown, the cleaning module 100 includes a cleaning component, which is mainly used to clean the roller surface of the conductive roller 200 to prevent the conductive roller 200 from being copper-plated.
[0042] Among them, see Figure 1 and Figure 2 As shown, the cleaning assembly includes a cleaning tank 110 and a cleaning member 112. The conductive roller 200 is located within the cleaning tank 110 and is capable of rotating relative to the cleaning tank 110, driving the copper foil to move during the rotation of the conductive roller 200. The cleaning member 112 is located within the cleaning tank 110 and has a cleaning port. This cleaning port corresponds to the conductive roller 200 located within the cleaning tank 110 and can spray cleaning liquid toward the conductive roller 200 to remove the copper sulfate solution on the surface of the conductive roller 200, thereby preventing copper plating on the surface of the conductive roller 200.
[0043] It is understandable that since the conductive roller 200 will move the copper foil during rotation, in order to prevent the cleaning liquid from directly acting on the copper foil, the cleaning port rinses the side of the conductive roller 200 where the copper foil is not attached.
[0044] In addition, the conductive roller 200 rotates in the cleaning tank 110 , so that the cleaning member 112 can clean the roller surface of the conductive roller 200 more carefully, thereby preventing the conductive roller 200 from being copper-plated.
[0045] It is worth mentioning that the cleaning liquid after cleaning the conductive roller 200 remains in the cleaning tank 110. In order to remove the cleaning liquid in the cleaning tank 110 in time and avoid affecting the cleaning efficiency, the cleaning tank 110 is also provided with a drain port.
[0046] In an embodiment of the present application, at least one drain port is provided at the bottom of the cleaning tank 110. By providing at least one drain port at the bottom of the cleaning tank 110, the cleaning liquid can flow out from the drain port by utilizing its own gravity, thereby reducing the use of a power device and thereby reducing production costs.
[0047] For example, two drain ports are provided at the bottom of the cleaning tank 110 , and the two drain ports are spaced apart from each other so that the cleaning liquid in the cleaning tank 110 can be discharged in time.
[0048] In the examples of this application, see Figure 1 As shown, the cleaning module 100 also includes a drainage assembly. The drainage assembly includes a reservoir 120 that collects the cleaning liquid discharged from the drain port. This reservoir 120 collects the cleaning liquid after cleaning the conductive roller 200, preventing the cleaning liquid from mixing with other aqueous solutions and reducing wastewater treatment costs.
[0049] That is to say, through this cleaning component and drainage component, the copper sulfate solution on the surface of the conductive roller 200 can be rinsed to prevent the conductive roller 200 from being copper-plated, and the cleaning liquid after cleaning the conductive roller 200 can be discharged separately to reduce wastewater treatment costs.
[0050] In the embodiment of the present application, the drain port is provided on the bottom wall of the cleaning tank 110 so as to discharge the cleaning liquid in the cleaning tank 110 in a timely manner and avoid accumulation in the cleaning tank 110 to affect the cleaning effect of the conductive roller 200 .
[0051] In an embodiment of the present application, the liquid storage tank 120 is located below the cleaning tank 110, and the groove of the liquid storage tank 120 corresponds to the drain port, that is, the drain port is located directly above the groove of the liquid storage tank 120. The cleaning liquid discharged from the drain port can be directly discharged into the liquid storage tank 120. The discharge path is short, the discharge of the cleaning liquid is smoother, and the cleaning liquid in the cleaning tank 110 can be discharged faster.
[0052] In the examples of this application, see Figure 1 and Figure 3As shown, the cleaning module 100 further includes a drain pipe 130, which is disposed at the drain port and extends toward one side of the liquid outlet tank, i.e., it extends vertically downward. Drain pipe 130 discharges the cleaning liquid after cleaning the conductive roller 200 into the groove of the liquid reservoir 120, ensuring that the cleaning liquid is completely collected in the liquid reservoir 120, preventing splashing of the cleaning liquid and ensuring the quality of the copper foil and the cleanliness of other components.
[0053] In the examples of this application, see Figure 3 As shown, one end of the drain pipe 130 is connected to the drain port, and the other end extends into the liquid storage tank 120 to further prevent the cleaning liquid from splashing out, thereby ensuring the quality of the copper foil and the cleanliness of other components.
[0054] In this embodiment of the present application, the liquid reservoir 120 is provided with at least one drain port 1200 for draining the cleaning liquid from the reservoir 120. This prevents the cleaning liquid from accumulating in the reservoir 120 and allows the cleaning liquid to flow smoothly into the reservoir 120, preventing overflow and contamination of the copper foil or components. The cleaning liquid discharged through the drain port 1200 is stored separately in the storage chamber and processed separately, reducing wastewater treatment costs.
[0055] For example, see Figure 1 As shown, the liquid storage tank 120 is provided with two discharge ports 1200 , which can discharge the cleaning liquid in the liquid storage tank 120 in time to prevent the cleaning liquid from accumulating in the liquid storage tank 120 .
[0056] It is worth mentioning that see Figure 4 and Figure 5 As shown, in order to discharge the cleaning liquid in the liquid storage tank 120 , a liquid pipe 140 is provided at the discharge port 1200 for discharging the cleaning liquid in the liquid storage tank 120 .
[0057] In the examples of this application, see Figure 1As shown, the liquid storage tank 120 includes a liquid storage bottom wall, a first liquid storage side wall 1201, a second liquid storage side wall 1202, a first baffle 1203, and a second baffle 1204. The liquid storage bottom wall and the drain pipe 130 are perpendicular to each other. The first liquid storage side wall 1201 and the second liquid storage side wall 1202 are disposed opposite each other and connected to opposite edges of the liquid storage bottom wall. A drain port 1200 is provided at the bottom of the first liquid storage side wall 1201 for draining the cleaning liquid from the liquid storage tank 120. The first baffle 1203 and the second baffle 1204 are disposed opposite each other, and are respectively disposed on opposite sides of the first liquid storage side wall 1201 and the second liquid storage side wall 1202 in the longitudinal direction. The first baffle 1203 and the second baffle 1204 are both connected to the first liquid storage side wall 1201 and the second liquid storage side wall 1202. That is, the liquid storage bottom wall, the first liquid storage side wall 1201 , the second liquid storage side wall 1202 , the first baffle 1203 and the second baffle 1204 form the liquid storage tank 120 .
[0058] In order to enhance the stability of the cleaning module 100 , the first liquid storage sidewall 1201 is connected to the cleaning tank 110 , and one end of the first baffle 1203 and the second baffle 1204 are connected to the cleaning tank 110 .
[0059] In addition, the other ends of the first baffle 1203 and the second baffle 1204 are extended vertically downward, and the height of the first baffle 1203 and the second baffle 1204 is greater than the height of the first liquid storage side wall 1201 and the second liquid storage side wall 1202. The other ends of the first baffle 1203 and the second baffle 1204 are connected to the machine to fix the cleaning module 100 on the machine so that the conductive roller 200 can be cleaned smoothly.
[0060] It is worth mentioning that the height of the first liquid storage side wall 1201 is greater than the height of the second liquid storage side wall 1202, that is, the second liquid storage side wall 1202 is not connected to the cleaning tank 110, so as to facilitate real-time observation of the liquid level changes in the liquid storage tank 120 and timely adjustment of the discharge size of the discharge port 1200.
[0061] In addition, one end of the drain pipe 130 should have an overlapping area with the second liquid storage side wall 1202 , that is, the drain pipe 130 extends into the liquid storage tank 120 and the cleaning liquid will not splash out of the liquid storage tank 120 .
[0062] The height of the discharge port 1200 may be lower than or equal to the height of the second liquid storage side wall 1202 , as long as the cleaning liquid in the liquid storage tank 120 can be discharged in time.
[0063] In the embodiment of the present application, the width of the first baffle 1203 and the second baffle 1204 is greater than the width of the first liquid storage side wall 1201 and the second liquid storage side wall 1202 to further enhance the stability of the cleaning module 100 and increase the connection stability with the machine.
[0064] In the embodiment of the present application, the cleaning tank 110 is a square structure. Figure 1 As shown, the cleaning tank 110 includes a cleaning bottom wall, a first cleaning side wall 1100, a second cleaning side wall 1101, a third cleaning side wall 1102, and a fourth cleaning side wall 1103. The first cleaning side wall 1100, the second cleaning side wall 1101, the third cleaning side wall 1102, and the fourth cleaning side wall 1103 are sequentially connected and arranged around the outer edge of the cleaning bottom wall. The conductive roller 200 is rotatably mounted on the second cleaning side wall 1101 and the fourth cleaning side wall 1103 at its axial ends. The cleaning bottom wall is connected to the first liquid storage side wall 1201, and the second cleaning side wall 1101 and the fourth cleaning side wall 1103 are connected to the first baffle 1203 and the second baffle 1204, respectively, to ensure that the various structures of the cleaning module 100 are more stable and less likely to separate. The first cleaning sidewall 1100 is provided on one side of the cleaning bottom wall close to the roughening tank 300 or the solidification tank 400. The first cleaning sidewall 110 can separate the cleaning tank 110 from the roughening tank 300 and the solidification tank 400 so as to retain the copper sulfate solution in the roughening tank 300 and the solidification tank 400 and reduce copper loss.
[0065] In the examples of this application, see Figure 2 As shown, the cleaning member 112 includes a cleaning pipe 1120 and a plurality of nozzles 1121 disposed on the cleaning pipe 1120. The plurality of nozzles 1121 are spaced apart from each other on the cleaning pipe 1120. The plurality of nozzles 1121 are located within the cleaning tank 110, while some cleaning pipes 1120 are located outside the cleaning tank 110 for supplying cleaning fluid. The nozzles 1121 are provided with cleaning ports, which are positioned corresponding to the conductive roller 200 and are used to spray cleaning fluid, such as water, onto the conductive roller 200 to clean the conductive roller 200.
[0066] Among them, in order to improve the cleaning efficiency of the conductive roller 200, the nozzle 1121 is arranged below the conductive roller 200, and the bottom of the conductive roller 200 is sprayed for cleaning, which can avoid the cleaning liquid from being directly sprayed onto the copper foil, thereby ensuring the quality of the copper foil; by spraying water on the conductive roller 200 to clean the copper sulfate solution on the conductive roller 200, the probability of copper plating on the conductive roller 200 can be reduced.
[0067] It is worth mentioning that this cleaning part 112 uses a nozzle 1121 and a cleaning pipe 1120 to form a nozzle 1121 type cleaning pipe 1120. It can not only ensure the water washing effect of the roller surface of the conductive roller 200, but also reduce water consumption, making its water washing pressure stronger and the flushing effect better.
[0068] In the embodiment of the present application, the plurality of nozzles 1121 are spaced apart along the length of the cleaning tube 1120 , and the ratio of the spacing between two adjacent nozzles 1121 to the length of the cleaning tube 1120 is in the range of 0.05 to 0.06.
[0069] For example, one cleaning pipe 1120 is connected to 16 nozzles 1121 , the spacing between the nozzles 1121 is 90 mm, and the length of the cleaning pipe 1120 is 1400 mm.
[0070] It should be understood that when cleaning element 112 comprises 16 nozzles 1121, and each nozzle 1121 is spaced 90 mm apart on a 1400 mm long cleaning pipe 1120, each nozzle 1121 can spray a fan-shaped water mist, and each fan-shaped water mist intersects. As a result, cleaning element 112 has a strong water pressure and a good flushing effect. Furthermore, a single cleaning pipe 1120 consumes approximately 2 m³ / h of water, significantly saving water.
[0071] That is to say, the liquid spraying areas of two adjacent nozzles 1121 overlap, which can ensure the cleaning effect of the roller surface of the conductive roller 200 and make the cleaning of the conductive roller 200 more detailed.
[0072] In the embodiment of the present application, the liquid spraying area of each nozzle 1121 is a fan-shaped area, and the central angle thereof is in the range of 30° to 60°.
[0073] Optionally, the central angle of the sector-shaped area is 30°, 45°, 50°, 55°, or 60°.
[0074] Of course, in other embodiments, the spraying area of each nozzle 1121 may not be entirely a fan-shaped area, and the range of the central angle may not be entirely 30° to 60°, as long as the spraying areas of two adjacent nozzles 1121 overlap with each other.
[0075] Example 2
[0076] The second embodiment of the present application provides a copper foil production system 10, see Figure 1 and Figure 6As shown, it includes a roughening tank 300, a curing tank 400, and any cleaning module 100 described in Example 1. The copper foil passes through the roughening tank 300 and the curing tank 400 for roughening and curing, leaving a large amount of copper sulfate solution attached to the surface of the copper foil. When the copper foil is transferred to the conductive roller 200, the copper sulfate solution adheres to the conductive roller 200. The cleaning port on the cleaning member 112 sprays cleaning liquid onto the roller surface of the conductive roller 200 that is not covered by the copper foil to remove the copper sulfate solution from the conductive roller 200 and prevent copper plating on the conductive roller 200.
[0077] In addition, the cleaning liquid after cleaning is discharged into the liquid storage tank 120 through the liquid drain port, and the cleaning liquid is treated separately, which reduces the wastewater treatment cost.
[0078] That is, the cleaning module 100 can remove the copper sulfate solution on the conductive roller 200 and discharge the cleaning liquid after cleaning the conductive roller 200 into the liquid storage tank 120. The cleaning liquid is discharged separately, which reduces the wastewater treatment cost.
[0079] It should be understood that the roughening tank 300 and the curing tank 400 are both provided with conductive rollers 200 to transport the copper foil out.
