Description

Technical Field

[0001] The invention relates to the technical field of electrolysis, in particular to an electrolytic copper foil electrodeposition device. Background Art

[0002] Electrodeposition of electrolytic copper foil is a process in which an electric current is passed through an aqueous solution or suspension to deposit certain substances on an electrode. In this process, an insoluble anode is usually used, and under the action of direct current, the ions of the metal to be extracted (such as copper ions) are reduced and deposited on the cathode. For the production of electrolytic copper foil, the copper raw material is made into a copper sulfate solution, and then the solution is electrolytically deposited into copper foil under the action of direct current using electrolytic equipment.

[0003] In order to increase the discharge speed of copper foil after electrolysis, the cathode is generally driven to rotate by a guide roller in cooperation with a winding roller. During the rotation, the copper foil formed on the outside of the cathode moves outward and then is wound on the winding roller. However, since the cathode is in contact with the outside world during the rotation, impurities from the outside world are brought into the electrolyte and dissolved into the electrolyte, thereby reducing the purity of the electrolyte. This will affect the deposition speed and quality of the copper foil. At the same time, the presence of impurities may interfere with the reduction process of copper ions, resulting in reduced electrolysis efficiency.

[0004] At the same time, impurities may also form insoluble deposits that adhere to the electrode surface, further affecting the electrolysis efficiency. Therefore, it is necessary to frequently inspect and clean the electrode surface. In the process of inspecting the electrode surface, when inspecting the cathode, the rotating cathode can be inspected in all directions from the outside. The cathode is generally installed above the anode, so the anode can generally only be taken out of the electrolysis box for inspection. At the same time, multiple installation and disassembly of the cathode and anode may cause the installation position to shift, resulting in unequal distances between the cathode and the anode. Then, when the current passes through the electrolyte, its density distribution will become uneven. The current density is higher in areas with closer distances, while the current density is lower in areas with farther distances. This uneven current density distribution will cause uneven thickness of the copper foil during the deposition process, affecting the flatness and uniformity of the copper foil.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The embodiment of the present application provides an electrolytic copper foil electrodeposition device, which solves the problem that during the process of detecting the electrode surface, the rotating cathode can be detected in all directions from the outside when detecting the cathode. The cathode is generally installed above the anode, so the anode can generally only be removed from the electrolytic box for detection. At the same time, multiple installation and disassembly of the cathode and the anode may cause the installation position to shift, thereby causing the problem of unequal distances between the cathode and the anode. Before the electrodeposition work is carried out, the detection unit 3 can first detect the flatness of the outer sides of the cathode part 13 and the anode part 14 in the deposition box 11. When the flatness of the outer sides of the cathode part 13 and the anode part 14 fails the detection, the lifting unit 2 can drive the cathode part 13 and the anode part 14 to move vertically through the moving seat 12 until the cathode part 13 and the anode part 14 can be moved to the outside. At this time, it is convenient to clean the deposits formed by impurities on the outside of the cathode part 13 and the anode part 14. After the cleaning, the electrodeposition work can be carried out again. The surface detection efficiency is high and targeted cleaning work can be carried out. On the other hand, the detection work can be carried out without disassembling the cathode part 13 and the anode part 14, thereby reducing the number of installation and disassembly of the cathode part 13 and the anode part 14 and avoiding the situation where the distance between the cathode part 13 and the anode part 14 is unequal.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

At this time, it is convenient to clean the deposits formed by impurities on the outer side of the cathode part 13 and the anode part 14. After cleaning, the electro-deposition work can be carried out again. The surface detection efficiency is high and targeted cleaning work can be carried out. On the other hand, the cathode part 13 and the anode part 14 do not need to be disassembled for detection work, which reduces the number of installation and disassembly of the cathode part 13 and the anode part 14 and avoids the situation where the distance between the cathode part 13 and the anode part 14 is unequal.

After the copper ions in the electrolyte are exhausted, it is necessary to inject electrolyte into the space between the cathode part 13 and the anode part 14, so that the upper layer of electrolyte spreads onto the sealing strip 121 until it enters the bottom of the sedimentation box 11 through the connecting port 122 on the sealing strip 121, so that the space between the cathode part 13 and the anode part 14 is refilled with the electrolyte rich in copper ions.
