Copper scale sweeping device

Abstract

The invention discloses a copper scale sweeping device which comprises at least one roller set and at least one pressure unit. The roller set is provided with two free rollers which are arranged oppositely. Each free roller is provided with a symmetric surface and supported by a roller shaft. The pressure units are arranged on the roller shafts correspondingly and drive the symmetric surfaces of the two free rollers to face each other so as to from clamping force. The extension lines of the roller shafts of the two free rollers intersect, so that the opposite symmetric surfaces define a feed end and a sweeping end. The feed end is connected with and leads in copper foil, and then the sweeping end clears away copper scale of the copper foil. According to the copper scale sweeping device, byarranging the two free rollers of the roller set at the cutting edge for copper foil slitting, the copper scale produced during cutting for copper foil slitting can be effectively swept away, puzzling problems of subsequent processing are effectively solved, and the practical effectiveness is good.

Description

technical field [0001] The invention relates to a device for removing copper scrap, in particular to a device for removing copper scrap by force. Background technique [0002] In the printed circuit board industry and battery industry, copper foil is the key material, including electrolytic copper foil and rolled copper foil, both of which have different crystal phase structures. Among them, the bright surface treatment, nodulation treatment and etching performance of copper foil are considered in industrial application, and electrolytic copper foil with fast etching speed, large etching factor, close to vertical structure, neat crystal orientation and high etching performance can be expected. However, the copper nodules of electrolytic copper foil are relatively large. When the copper foil is slit, it is easy to produce copper powder, copper nodules and other copper scraps on the cutting edge of the copper foil. Chips detached between the two conductors may cause a short c...

AI Technical Summary

Problems solved by technology

However, the copper nodules of electrolytic copper foil are relatively large. When the copper foil is slit, it is easy to produce copper powder, copper nodules and other copper scraps on the cutting edge of the copper foil. If the shavings are separated between the two conductors, it may cause a short circuit or poor insulation, which will cause a breakdown of the electrical product, and may even cause disasters such as overheating, fire or explosion of the battery.

At present, although there are some control measures for copper shavings in the manufacturing process, if the copper foil material itself is not removed, these hidden worries cannot be effectively avoided, and there is a need for improvement
