Problems solved by technology

[0003] The most commonly used method for the existing copper powder treatment method is the manual method, that is, manually use a sticky cloth to wipe the end face of the rolled copper foil or use the stickiness of the sticky paper to stick the copper scraps away, which often results in incomplete cleaning and incomplete cleaning. Wiping or sticking traces are left on the copper foil end face, which is time-consuming and labor-intensive

Embodiment 1

[0032] refer to figure 1 with figure 2 As shown, a copper foil slitting and cleaning device includes a rewinding roller 1 and an unwinding roller 2 that cooperate with each other. Between the rewinding roller 1 and the unwinding roller 2, a slitting area 3, In the cleaning area 4 and the drying area 5, the copper foil located in the slitting area 3 is arranged along the horizontal direction. When the copper foil is slit, the horizontal slitting method is generally adopted, so in the slitting area 3, the end face of the copper foil is along the horizontal direction. Orientation settings.

[0033] A copper foil reversing mechanism 6 is provided between the slitting area 3 and the cleaning area 4. The copper foil reversing mechanism 6 consists of a horizontal guide roller 6a arranged in the horizontal direction and a reversing roller arranged obliquely on the side of the horizontal guide roller 6a. Composed of guide roller 6b; the reversing guide roller 6b is located on the si...

Embodiment 2

[0047] refer to image 3 As shown, in a copper foil slitting and cleaning device of this embodiment, the structure of the cleaning device is basically the same as that of the cleaning device in Embodiment 1, the only difference is that the number of the 9 guide rollers is two , the feed roller 7, the discharge roller 8 and two guide rollers 9 cooperate to make the copper foil advance along the S-shaped path; the mounting plate 10 is arranged on the outside of the S-shaped path conversion part, and the nozzles 11 are distributed on the mounting plate 10 on the inner end face. By adopting this structure, the length of the equipment can be effectively shortened, and the occupied area of ​​the equipment can be reduced. At the same time, both sides of the copper foil can be cleaned.

[0048] In a copper foil slitting cleaning method of this embodiment, the cleaning method is basically the same as the cleaning method in Embodiment 1, the only difference is that: step (3) is specifi...

Abstract

The invention discloses a copper foil slitting and cleaning device and a copper foil slitting and cleaning method and belongs to the technical field of copper foil cleaning. The copper foil slitting and cleaning device is characterized by comprising a winding roll and an unwinding roll which are matched with each other, a slitting area, a cleaning area and a drying area are arranged between the winding roll and the unwinding roll horizontally sequentially, and a copper foil positioned in the slitting area is arranged horizontally; a copper foil reversing mechanism is arranged between the slitting area and the cleaning area, and the copper foil positioned in the cleaning area and the drying area is arranged vertically after passing through the copper foil reversing mechanism; feeding rolls, discharging rolls and at least one guide roll are arranged in the cleaning area vertically; a mounting plate is arranged on each of two sides of the copper foil between the feeding rolls and the discharging rolls, and a plurality of spray nozzles opposite to the copper foil are distributed on each mounting plate; a brush cleaning portion is arranged at the side edges of the spray nozzles on the side close to the discharging rolls; a wastewater pool is arranged on the lower sides of the mounting plates. The copper foil slitting and cleaning device and the copper foil slitting and cleaning method are used for cleaning copper foils, and convenience in use and good effects are achieved.

Description

technical field [0001] The invention relates to a cleaning device, more specifically, to a copper foil cutting and cleaning device which is convenient to use and has good effect. The invention also relates to a copper foil cutting and cleaning method. Background technique [0002] The application fields of electrolytic copper foil are very wide, such as printed circuit boards, lithium battery cathode manufacturing, copper clad laminates, etc. When the copper foil is bound to carry copper powder during the slitting process, if it is not treated, if it is directly applied to the lithium battery cathode, it will cause the diaphragm between the cathode and anode of the lithium battery to form a short circuit, thereby improving the electrochemical performance of the lithium battery. severely affected. Therefore, how to deal with the copper powder formed in the copper foil slitting process has always been an aspect of concern in the development of copper foil production technolo...
