An electrolytic copper foil cutting device

Abstract

The invention discloses an electrolytic copper foil cutting device, which comprises a casing with openings at both ends, sealed guide rollers fixedly installed at both ends of the opening of the casing, and a dust collecting seat fixedly installed in the casing, which is arranged above the dust collecting seat and The cutting idler roller connected with the casing in rotation, the cutting knife arranged above the cutting idler roller and slidingly connected with the casing, the first dust removal roller and the second dust removal roller arranged on one side of the dust collecting seat, the first dust removal roller and the The second dust removal roller is rotatably installed on the casing, and the first dust removal roller is arranged above the second dust removal roller; the cutting device can reduce the copper powder adhering to the surface of the copper foil on the one hand and make the adhering The copper powder is mainly concentrated on the two sides of the cutting, and then the attached copper powder is cleaned and transferred to ensure the quality of the produced copper foil, and the collected copper powder can also be transferred in time to ensure that after a long period of cleaning work, Still able to maintain a good cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of electrolytic copper foil processing, and in particular relates to an electrolytic copper foil cutting device. Background technique [0002] Electrolytic copper foil is an important material for the manufacture of copper clad laminates, printed circuit boards, and lithium-ion batteries. The production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product cutting. The edge of the formed copper foil is cut to form a smooth and flat edge, and then the formed copper foil is rolled and packaged. [0003] During the slitting process of electrolytic copper foil, the vibration of the cutting device, the condition of the cutting tool, and the relative movement between the copper foil and the cutting device will cause copper powder to be produced during the slitting process. If these copper powders are not treated in time After processing, th...

Problems solved by technology

[0003] During the slitting process of electrolytic copper foil, the vibration of the cutting device, the condition of the cutting tool, and the relative movement between the copper foil and the cutting device will cause copper powder to be produced during the slitting process. If these copper powders are not treated in time After processing, the copper powder produced by slitting will adhere to the surface of the copper foil, causing these aluminum foils to easily cause quality problems during application, such as breakdown accidents when used in lithium batteries, and short circuits when used on circuit boards. In the production process of copper foil, it is necessary to deal with the copper powder produced in the production process in time to improve the quality of the formed electrolytic copper foil. In the prior art, it is mainly through manual cleaning and mechanical cleaning. The former The cost is high and the efficiency is low. The latter is easy to absorb copper powder after cleaning for a long time, resulting in the gradual decline of the cleaning effect as the cleaning progresses. , an electrolytic copper foil slitting device that ensures the quality of the slit-formed copper foil, the present invention provides the following technical solutions
