Description

Technical Field

[0001] The utility model relates to the technical field of film processing equipment, in particular to a polyimide film surface treatment device. Background Technique

[0002] The polyimide film is a film with high temperature resistance, chemical corrosion resistance, radiation resistance and electrical insulation. It can be used for a long time in a high-temperature environment and is extremely suitable for use as a flexible circuit board substrate. It can also be used as various electrical insulation materials. Since the chemical properties of polyimide are stable, polyimide can prevent combustion without adding a flame retardant, and the polyimide film has a high tensile strength.

[0003] During the production process of the polyimide film, in order to ensure the flatness of the thin surface, generally, a flattening plate is added during the conveying process to flatten the polyimide film. For example, the Chinese utility model patent with the publication number of CN220986182U specifically discloses a surface treatment device for polyimide films.

[0004] However, in the actual use process of the above polyimide film surface treatment equipment, people will find that although the device is provided with multiple cleaning rods on the stretching rod, the polyimide film can be cleaned by the cleaning rods, but only one side can be cleaned. And because the cleaning rods are arranged on the stretching rod and there are gaps between multiple cleaning rods, it is difficult for the flattening plate to cooperate with the stretching rod to flatten the polyimide film, which greatly reduces its practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a polyimide film surface treatment device to solve the problems raised in the above background technique.

During the process, the polyimide film is flattened by the cooperation of the pressure roller and the flattening plate, and the upper and lower surfaces of the polyimide film are cleaned by the first cleaning rod and the second cleaning rod. The first cleaning rod and the second cleaning rod can use dust sticking rollers or electrostatic dust removal rollers.

[0008] Preferably, positioning rods parallel to each other are arranged on the side of the lead screw. The positioning rods penetrate through the bracket and are fixed to the third roller bracket. A positioning block is fixed to the top of the positioning rod. The arranged positioning rods are used to limit the third roller bracket.

[0009] Preferably, reinforcing plates are arranged at the bottoms of the first roller bracket and the second roller bracket. The arranged reinforcing plates are used to improve the supporting effect of the first roller bracket and the second roller bracket.
