Abstract

The invention relates to the technical field of corona treatment, in particular to a protective film corona treatment device capable of automatically adjusting the corona distance. The protective filmcorona treatment device comprises a rack, wherein the rack is provided with an upper traction roller, a forward corona roller, a forward corona electrode set, a lower traction device, a reverse corona roller and a reverse corona electrode set, wherein a transparent upper auxiliary roller and a transparent lower auxiliary roller are arranged on the rack, magnetostrictive sensors are arranged in the upper auxiliary roller and the lower auxiliary roller, and a micro magnetic block is arranged on the protective film. A circumferential magnetic field generated by a waveguide tube in the magnetostrictive sensors can be intersected with a magnetic field generated by the micro magnetic block, the pulse signals received by an electronic chamber are converted into corresponding electric signals, asignal processing system is used for identifying and calculating the width characteristic of the protective film according to the distribution of the electric signals, the number of the required corona electrodes is automatically adjusted by a control system, so that the energy consumption is effectively reduced, and the problem that the protective film corona treatment device in the prior art cannot adapt to protective films of different sizes is solved.

Description

technical field [0001] The invention relates to the technical field of corona treatment, in particular to a protective film corona treatment device for automatically adjusting the corona distance. Background technique [0002] Corona treatment is an electric shock treatment that makes the surface of the substrate more adherent. In order to meet the needs of production, it is necessary to perform corona treatment on the protective film to improve the adhesion of the protective film. At present, the protective film corona treatment device in the prior art generally has a single function and cannot meet the requirements in the actual production process. Different types of protective films have different thicknesses and widths. Workers can only use a fixed amount of energy to corona when operating the corona treatment device, which will inevitably result in waste of resources and energy. At the same time, the corona will generate high temperature, and the high temperature will...
