Description

Technical Field

[0001] The utility model belongs to the technical field of copper foil production, and in particular relates to a pull-out dust-adhesive roller device for a surface post-processing machine. Background Art

[0002] With the advent of the 5G era, the demand for copper foil continues to increase, and high-frequency and high-speed copper clad laminates and high-quality, ultra-thin copper foils will become the mainstream development direction of market demand. In the production process of ultra-thin copper foil, the thickness of the material is very thin (measured in microns), and it is collected in a roll-up manner, so the material is extremely sensitive to surface foreign matter. Once the surface foreign matter is not handled in time, it is easy to form a pressure pit on the surface of the material, resulting in defective products. In addition, copper powder will inevitably be generated when the copper foil is sheared in the copper foil slitting section. Once the copper powder flows into the PCB board production, it is easy to form a short circuit, causing the entire circuit board to be scrapped. Therefore, in order to ensure the cleanness of the copper foil surface, it is necessary to design a dust-removing roller device structure with low cost, reliable mechanical operation, simple structure, and easy replacement; the application number is 202210170018.0, and the name is a dust removal device for the surface of ultra-thin copper foil. In a device (hereinafter referred to as a comparative document), a dust removal method for the surface of copper foil is disclosed. Although the dust and foreign matter on the surface of the copper foil is effectively cleaned and the surface of the copper foil is ensured to be clean, in the comparative document, since the main driving roller 9 and the end of the dust removal roller are both installed on the same fixed side plate, the relative position adjustment range of the two is small. When the dust collecting roller 4 or the dust sticking roller 8 in the dust removal roller needs to be replaced, the replacement is difficult due to the small space, and the replacement cycle is long. In addition, there is a risk of damaging the main driving roller 9 during the replacement process. Therefore, it is necessary to make improvements to the above-mentioned problems.
