Detailed Description
The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1, the electron coating device for a film winding coater comprises an electron beam 1, a deflection coil 2, an electron gun 3 and a cold roller 4 for passing a film 5, wherein the electron beam 1 is emitted to the film 5 on the cold roller 4 through the electron gun 3, the electron beam 1 scans at a high speed under the action of the deflection coil 2 and scans and covers the width of the film 5, the film 5 is an insulator, and electrons are attached to the surface of the film 5.
Preferably, the electron gun 3 has a filament, and a dc voltage 6 is applied between the filament of the electron gun 3 and the cold roll 4.
Further, the direct-current voltage 6 is 4-10 kv, and the high-voltage power supply voltage is 4-10 KV adjustable constant-voltage power supply; the electron beam 1 current also needs constant current, and is in a constant voltage and constant current state during operation, so that electrons are stably emitted.
Further, since the film 5 is rapidly moved during vapor deposition, the deflection frequency of the deflection coil 2 is 300Hz to 3000Hz in order to match the moving speed of the film 5.
The electron gun 3 emits the electron beam 1 towards the film 5, the electron beam 1 scans at a high speed under the action of the deflection coil 2, the scanning width covers the width of the film 5, electrons are attached to the surface of the film 5 due to the fact that the film 5 is an insulator, electronic coating is achieved, 4 KV-10 KV direct current voltage 6 (adjustable according to process or equipment requirements) is applied between a filament of the electron gun 3 and the cold roller 4, and the film 5 is finally tightly adsorbed on the cold roller 4.
Due to the size limitation of the machine, the structural design of the electron gun 3 and the deflection yoke 2 is required to meet the requirement that the scanning width of the electron beam 1 reaches the width of the film 5 within a short distance, for example, the distance between the electron gun 3 and the film 5 in a prototype is adjustable by about 100 mm-800 mm, and the width of the film 5 is about 600 mm-3000 mm.
The energy distribution of the electron beam 1 is uniform, so that the electron distribution on the film 5 can be uniform, and the scanning driving circuit is required to have a scanning waveform correction function and can be adjusted according to actual conditions.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
Although terms such as the electron beam 1, the deflection yoke 2, the electron gun 3, the cold roll 4, the film 5, the direct voltage 6, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the invention; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present invention.
