Problems solved by technology

[0002] Copper foil is a negative electrolytic material. When in use, it needs to be pasted on the base layer of the circuit board. The coating of the copper foil needs to ensure the flatness of the surface and prevent wrinkles on the surface. The existing copper foil When the sheet is conveyed before lamination, due to the transmission deviation between the transmission structures in the equipment, the surface tension of the conveying copper foil may be too large or too small. When the tension is too large, the surface of the copper foil will be partially deformed, and if the tension is too small, the surface of the copper foil will be wrinkled. When the copper foil is coated, it will cause certain damage to the flatness of the coating. Influence, when the conveying direction of the copper foil is shifted, when the copper foil is coated, creases will appear on the surface, which will affect the effect of the copper foil coating

Abstract

The invention provides a copper foil laminating device with high flatness and capable of avoiding wrinkles, and relates to the technical field of copper foil laminating. The copper foil laminating device high in flatness and capable of avoiding wrinkles comprises an adjusting mechanism, a fixed shaft seat is arranged in the adjusting mechanism, a transmission shaft is rotatably connected to the interior of the fixed shaft seat, a groove disc is arranged on the surface of the transmission shaft, and a top plate is slidably connected to the side surface of the fixed shaft seat; according to the copper foil laminating device high in flatness and capable of avoiding wrinkles, through matched use of a transmission shaft and a groove disc, the positions of top plates can be adjusted, through matched use of the top plates, the effective diameters of the circumferences of the surfaces of a first tension roller and a second tension roller can be changed, and through matched use of the first tension roller and the second tension roller, the flatness is improved. The tension of the surface of the copper foil can be adjusted by changing the distance of the copper foil between the first tension roller and the second tension roller, the surface of the copper foil is prevented from being arranged too large or too small, and the flatness of the surface of the copper foil is guaranteed.

Description

technical field [0001] The invention relates to the technical field of copper foil coating, in particular to a copper foil coating device with high flatness and avoiding wrinkles. Background technique [0002] Copper foil is a cathodic electrolytic material. When using it, it needs to be attached to the base layer of the circuit board. The coating of copper foil needs to ensure the flatness of its surface and prevent wrinkles on its surface. The existing copper foil When the sheet is conveyed before lamination, due to the transmission deviation between the various transmission structures in the equipment, the surface tension of the copper foil in conveying may be too large or too small. When the tension is too large, the surface of the copper foil will be partially deformed. If the tension is too small, the surface of the copper foil will be wrinkled. When the copper foil is coated, the flatness of the coating will be affected to a certain extent. Influence, when the convey...
