Description

Technical Field

[0001] The invention relates to the technical field of electrolytic copper foil cleaning, and in particular to electrolytic copper foil cleaning equipment. Background Art

[0002] Electrolytic copper foil refers to a metal copper foil produced by electrolysis using copper as the main raw material. Specifically, it uses cathode copper or copper wire as the main raw material. In a dedicated electrolytic equipment, the copper ions in the copper sulfate solution are reduced to copper at the cathode through electrochemical deposition to form the original foil. Then, it is subjected to surface roughening, curing, heat-resistant layer, corrosion-resistant layer, anti-oxidation layer and other surface treatments. Among them, lithium battery copper foil is mainly subjected to surface organic anti-oxidation treatment. Finally, it is made into a finished product after slitting, testing and other steps.

[0003] At present, after the electrolytic copper foil is cleaned, it is blown dry by a hot air blower. Since a large amount of water adheres to the surface of the electrolytic copper foil, the efficiency of the drying of the electrolytic copper foil is affected, which needs to be improved. Summary of the invention

[0004] The object of the present invention is to provide an electrolytic copper foil cleaning device in order to improve the drying efficiency of the electrolytic copper foil.

[0005] The present invention provides an electrolytic copper foil cleaning device that adopts the following technical solution: it includes a cleaning box, the cleaning box is provided with a accommodating cavity, the inner wall of the accommodating cavity is connected with a spraying mechanism, a drying mechanism and a blowing mechanism, the drying mechanism is located between the spraying mechanism and the blowing mechanism, the drying mechanism includes two mounting blocks that are slidably connected in the accommodating cavity, the two mounting blocks are rotatably connected to the opposite sides with rotating rollers, the outer peripheral surface of the rotating roller is connected with a drying cloth for bonding with the electrolytic copper foil, and the cleaning box is connected with a driving component for driving the two mounting blocks to slide in a direction of approaching or moving away from each other.

[0006] By adopting the above technical solution, the electrolytic copper foil passes through the spray mechanism, the drying mechanism and the blowing mechanism in sequence, and the spray mechanism cleans the electrolytic copper foil first. The driving component drives the two mounting blocks to slide in the direction of approaching each other, so that the two drying cloths are respectively in contact with the two sides of the electrolytic copper foil. During the movement of the electrolytic copper foil, the electrolytic copper foil and the outer peripheral surface of the drying cloth are in active contact, and the drying cloth drives part of the moisture to separate from the electrolytic copper foil, and some of the moisture is absorbed by the drying cloth, thereby reducing the moisture adhering to the electrolytic copper foil and improving the efficiency of the electrolytic copper foil being blown by the blowing mechanism.

[0007] Optionally, the rotating roller is provided with two rotating posts, and the mounting block is provided with a rotating cavity for rotatingly cooperating with the corresponding rotating posts, and the opening of the rotating cavity is configured to be constricted.

[0008] By adopting the above technical solution, the mounting block is made of elastic material. When installing the rotating roller, the rotating column is inserted into the mounting cavity, and the rotating column drives the mounting block to produce elastic deformation, so that the opening size of the rotating cavity becomes larger, until the rotating column is completely inserted into the rotating cavity, and the mounting block is elastically reset, so that the opening size of the rotating cavity becomes smaller, thereby completing the installation of the rotating roller and preventing the rotating column from detaching from the mounting block during the rotation process.

[0009] Optionally, the mounting block is provided with two guide surfaces, the two guide surfaces are located at the opening of the rotating cavity, and the distance between the two guide surfaces decreases step by step toward the direction approaching the rotating cavity.

[0014] By adopting the above technical solution, when the mounting block slides, the guide block slides along the guide groove, and the sliding cooperation between the guide block and the guide groove plays a guiding and limiting role in the sliding of the mounting block, thereby improving the sliding stability of the mounting block and improving the abutment effect between the drying cloth and the electrolytic copper foil.

[0016] By adopting the above technical solution, the driving member drives the bidirectional screw rod around its own axis, so that the two limit blocks can slide in the direction of approaching or moving away from each other, that is, the two sliding seats can slide in the direction of approaching or moving away from each other, and the sliding cooperation between the limit blocks and the limit grooves can guide and limit the sliding of the sliding seat, thereby preventing the sliding seat from rotating during the sliding process.

[0018] By adopting the above technical solution, the pump is turned on, water enters the two connecting water pipes through the water inlet pipe, and the water in the connecting water pipes is discharged through each water outlet pipe, so that both sides of the electrolytic copper foil are washed by water.

The hot air in the connecting air ducts is discharged from each air outlet pipe, and the hot air dries both sides of the electrolytic copper foil.

[0021] Optionally, the cleaning box is connected to two groups of guide rollers, and the spraying mechanism, the wiping mechanism and the blowing mechanism are located between the two groups of guide rollers.

[0022] By adopting the above technical solution, the two groups of guide rollers play a guiding and limiting role in the movement of the electrolytic copper foil, thereby improving the effect of the electrolytic copper foil passing through the spraying mechanism, the wiping mechanism and the blowing mechanism in sequence.

[0023] Optionally, each group of guide rollers includes two guide rollers, the two guide rollers are rotatably connected to the cleaning box, and the two guide rollers are vertically arranged.

[0024] By adopting the above technical solution, the guide roller is vertically arranged, that is, the electrolytic copper foil moves vertically. After the electrolytic copper foil is washed with water, the moisture attached to the electrolytic copper foil is separated from the electrolytic copper foil under the influence of gravity, thereby reducing the moisture attached to the electrolytic copper foil and improving the efficiency of the electrolytic copper foil being dried by the drying mechanism.

[0025] In summary, the present invention includes at least one of the following beneficial technical effects:
