[0002] At present, copper foil is used to manufacture various products such as cathodes for secondary batteries and flexible printed circuit boards. This copper foil is manufactured by an electroplating method in which an electrolyte is provided between the positive electrode and the negative electrode to make an electric current flow. The copper foil has low surface oxygen characteristics and can adhere to various different substrates such as metals and insulating materials, and has a wide temperature range of use. It is mainly used for electromagnetic shielding and antistatic. Placing the conductive copper foil on the substrate surface and combining with the metal substrate has excellent conductivity and provides the effect of electromagnetic shielding. The demand for electronic-grade copper foil, especially high-performance electronic-grade copper foil, is increasing in the domestic and foreign markets. At present, it is usually inconvenient to replace the winding roller during the winding process of copper foil processing, resulting in low winding efficiency, and foreign objects adhere to the surface of the wound copper foil for a long time, which is easy to damage the surface of the copper foil.

When fixing, only the clamping bracket needs to be moved. The fixing operation is simple and easy to use.

[0020] 2. A winding device for copper foil processing is provided with a winding sleeve. Since the outer side surface of the winding sleeve is flush with the top of the fixed seat, when the copper foil is fixed in the clamping groove, the winding shaft is driven to rotate by the driving motor, and the winding shaft drives the winding sleeve to rotate through the fixed seat, so that the copper foil can be rolled up to the top of the winding sleeve. When the winding is completed, the limiting device is removed from the winding shaft, and the winding sleeve can be removed from the winding shaft. When the winding sleeve slides on the winding shaft, it drives one end of the copper foil to slide in the clamping groove, and the winding sleeve is disengaged from one end of the winding shaft. When one end of the copper foil is disengaged from the clamping groove, the removal of the winding sleeve is completed, and then a new winding sleeve can be installed. The replacement operation is convenient, and the removed winding sleeve can be directly drawn out from the copper foil rolled thereon, so that the copper foil can be stored separately and the winding sleeve can be reused.

[0021] 3. A winding device for copper foil processing, when the winding sleeve is winding the copper foil, the thickness of the rolled copper foil on the winding sleeve gradually increases, so that one side of the rolled copper foil gradually extends to the inside of the concave-shaped limit clamp. When the winding is completed, the limit clamp is driven to move downward by the extension of the telescopic push rod, and the limit clamp drives the rolled copper foil to move downward, and the copper foil drives the winding sleeve to move downward, so that the winding sleeve and the rolled copper foil thereon can be removed from the winding shaft together, and the rolled copper foil can be automatically removed without manual operation, which is easy to use and has good safety.

And when winding, the top of the supporting disk closely adheres to the lower part of the winding sleeve and the copper foil on the winding sleeve. When it is necessary to rotate and remove the limiting device, the limiting disk rotates, and the supporting disk does not rotate under the action of friction, which can avoid the friction between the limiting device and the copper foil from damaging the side of the copper foil, and is convenient for protecting the copper foil from damage during disassembly.

[0023] 5. The winding device for copper foil processing is provided with a cleaning device. When winding, one end of the copper foil passes through the channel of the feeding cylinder and is fixed on the winding device.
