Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of copper foil production and processing, and particularly relates to a copper foil on-line slitting device. BACKGROUND
[0002] In the copper foil electroplating process, due to the existence of edge effect, more metal copper is deposited at the edge part of the copper foil than at the middle part, thereby causing thick edge phenomenon. This thick edge problem brings many troubles to the subsequent winding and application of the copper foil. On the one hand, the thick edge will cause the copper foil to be unable to be tightly and neatly wound in the winding process, and problems such as wrinkles and deviation are prone to occur, which seriously affects the winding quality and reduces the yield of products. On the other hand, in some application scenarios with extremely high requirements for the uniformity of the thickness of the copper foil, such as lithium battery manufacturing, electronic circuit board and the like, the copper foil with thick edge cannot meet the use requirements, resulting in a decrease in product performance and even failure.
[0003] At present, the industry mainly adopts post-processing or off-line slitting to solve the problem of thick edge of the copper foil. The post-processing has low efficiency, and the processing effect varies from person to person, so it is difficult to ensure the consistency of the quality. The off-line slitting needs to take the copper foil off the production line, and after going through multiple processes, the copper foil is reinstalled on the production line for winding, which not only increases the production cost and time cost, but also easily causes secondary damage to the copper foil in the process of carrying and reinstallation. Therefore, it has important practical significance to develop an on-line slitting device which can realize real-time slitting of the thick edge of the copper foil on the production line and ensure smooth winding of the product.
[0004] Therefore, the application provides a copper foil on-line slitting device. SUMMARY

The outer walls on both sides of the cylinder 53 are provided with annular grooves 54 arranged at intervals to provide slitting grooves, which facilitates precise slitting by the disc slitting blade 9 and makes the cut more even.
[0029] The slitting mechanism is mounted on the slitting bracket 3 and includes a sliding guide roller 6.

Through precise adjustment of the micrometer, the slitting position can be finely adjusted to adapt to the slitting requirements of copper foils of different widths and thicknesses.
