Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foils, and particularly to an edge polishing device for a copper foil making machine. Background Art

[0002] The core equipment for preparing electrolytic copper foils is a copper foil making machine, which mainly consists of an anode tank (with anode plates inside), a cathode roller, other guide rollers, and motors. During the copper foil making process of the copper foil making machine, copper needles and long copper phenomena are likely to occur at the edge of the cathode roller, which will cause the bonding force between the copper foil and the edge of the cathode roller to be too large, and then it is difficult to peel off the copper foil at the edge of the cathode roller, resulting in torn edges of the copper foil. When the foil tears, the width of the copper foil decreases accordingly. At the same time, the remaining foil after tearing still adheres to the surface of the cathode roller. As the cathode roller rotates continuously, it is very easy to enter the electrolytic cell, causing a short circuit between the cathode and anode of the electrolytic cell, punching through the surface of the cathode roller, and causing a major accident of scrapping the cathode roller. Some manufacturers currently use manual operation and polishing cloth to clean the copper needles at the edge of the cathode roller. However, when polishing in this way, the applied force is uneven, which easily brings problems such as uneven polishing and inconvenient operation.

[0003] After retrieval, Patent CN220481312U uses a servo motor to drive a polishing wheel to polish the edge of the electrolytic copper foil, solving the problem of uneven polishing caused by previous manual operations. However, this patent uses an X-axis handwheel, an X-axis body, a Y-axis handwheel, and a Y-axis body to drive the polishing wheel, which can only move in the horizontal and vertical directions and cannot deflect at an angle, resulting in the problem that the local position at the edge of the cathode roller is not completely polished by this device.

[0004] In view of this, it is urgent to develop an edge polishing device for a copper foil making machine to solve at least one of the problems of uneven force application, uneven polishing in manual polishing, and incomplete polishing of local positions in automatic devices.
