Abstract
The static charge eliminator includes a charger including one or more charging units, and a grounded needle-shaped conductor. The charger is configured to charge an insulating film such that the absolute value of the surface potential of the insulating film is 3 kV or more. The needle-shaped conductor is arranged to generate a corona discharge between the needle-shaped conductor and the insulating film charged by the charger. Thereby, the static charges on the insulating film can be reliably eliminated.
Claims14
A static charge eliminator comprising:
- a charger including one or more charging units;
- and
- a grounded needle-shaped conductor, wherein
- the charger being configured to charge an insulating film by contacting the insulating film such that an absolute value of a surface potential of the insulating film is 3 kV or more,
- each of the one or more charging units includes a roller covered by an insulating member having a different level in a triboelectric series from the insulating film,
- the insulating member is configured to contact a surface of the insulating film, and
- a needle-shaped conductor is arranged to generate a corona discharge between the insulating film charged by the charger and the needle-shaped conductor.
A static charge elimination method comprising:
- charging an insulating film by bringing a charger into contact with a surface of the insulating film such that an absolute value of a surface potential of the insulating film is 3 kV or more;
- and
- generating a corona discharge between a grounded needle-shaped conductor and the charged insulating film, wherein
- the charging the insulating film includes bringing a roller covered by an insulating member having a different level in a triboelectric series from the insulating film into contact with the surface of the insulating film.
