Description

Technical Field

[0001] This utility model relates to the field of copper foil production technology, specifically a slitting device that can eliminate copper powder adhering to the surface of electrolytic copper foil. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as the conductor in the PCB. It easily adheres to the insulating layer, receives the printed protective layer, and is etched to form the circuit pattern. With the rapid development of integrated circuits towards high density, multilayering, and thinness, in addition to higher requirements for the intrinsic technical properties of copper foil such as tensile strength, elongation, and oxidation resistance, stringent requirements are also placed on its appearance quality. In particular, the presence of surface defects such as copper powder is strictly prohibited during copper foil slitting, as these directly affect the final manufacturing quality and performance of the circuit board. For example, during the production of printed circuit board products, circuit breakdown or short circuits can occur, seriously affecting the reliability and safety of the product.

[0016] This invention addresses the problem of copper powder easily adhering to the surface of copper foil during the cutting process in existing slitting devices. For example... Figure 1-2As shown, the following technical solution is provided: a slitting device for eliminating copper powder adhering to the surface of electrolytic copper foil, including an unwinding shaft 1 and a rewinding shaft 13, a slitting device support is provided between the unwinding shaft 1 and the rewinding shaft 13, a blade holder 14 is installed on the slitting device support, a cutter 8 is installed on the blade holder 14, a first adjusting roller 9 is provided on the side of the cutter 8 facing the unwinding shaft 1, the electrolytic copper foil 17 between the unwinding shaft 1 and the rewinding shaft 13 passes through the cutter 8 and the first adjusting roller 9, a blade cover 7 is provided on the upper side of the cutter 8 to partially cover the cutter 8 and the electrolytic copper foil 17, the blade cover 7 is connected to an air pump 11 through a hose 16, by setting the blade cover 7, the hose 16 and the air pump 11, the copper powder can be sucked away when the cutter 8 cuts the electrolytic copper foil 17, and the copper powder remaining on the copper foil can also be sucked away.

[0017] Specifically, the cutter 8 is driven by a motor, which can be mounted on the slitting device bracket. The blade holder 14 can adjust the distance between the cutter 8 and the electrolytic copper foil 17. An adjustment mechanism can be set on the blade holder 14 to finely adjust the position of the cutter 8. The adjustment mechanism can be an adjustment screw, which adjusts the position of the cutter 8 by rotating the screw.

[0018] The position of the first adjusting roller 9 in the slitting device bracket can be adjusted to adjust the width of the electrolytic copper foil 17 after it is cut.

[0019] The hose 16 is connected to the suction pump 11 by a clamp 12 to ensure a secure connection that is not easily loosened. The suction pump 11 is equipped with a copper powder collection device to collect the copper powder.

[0020] In this embodiment, the slitting device bracket includes side plates 18 on both sides and a top plate 15 disposed between the side plates 18. The blade cover 7 is fixed on the top plate 15. The side plates 18 can limit the splashing of copper powder to a relatively small space, and the top plate 15 facilitates the installation and setting of the blade cover 7.

[0021] In this embodiment, a second adjusting roller 10 is also provided below the cutter 8. The first adjusting roller 9 and the second adjusting roller 10 are both arranged between the side plates 18. The second adjusting roller 10 can adjust the orientation of the electrolytic copper foil 17 to facilitate the rapid winding of the winding shaft 13.

Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
