Abstract

A cutting apparatus for a separator of an electrical device cuts or severs a separator which includes a melt material representing a substrate and a heat-resistant material laminated on the melt material and having a higher melt temperature than the melt material. The separator cutting apparatus comprises at least two cutting members which are disposed spaced apart from one another, a first suction member, and second suction members. The cutting members cut the separator such that a cut piece generates. The first suction member moves the cut piece in a direction away from the separator while sucking the cut piece. The second suction members suck up the cutting dust produced accompanying the cutting process of the separator.

First claim

The invention claimed is:

1. A cutting apparatus for a separator of an electrical device, the separator including a melt material representing a substrate and a heat-resistant material laminated on the melt material and higher in melting point than the melt material, the cutting apparatus comprising:
at least two cutting members disposed spaced apart from each other for cutting the separator into a cut piece with opposing cut edges, the at least two cutting members moved to the separator and away from the separator with a moving device; and
a suction member comprising:
a suction producing mechanism;
a first suction unit providing a first suction opening that is configured to suck the cut piece with the first suction opening;
a second suction unit providing a second suction opening that is configured to suck through the second suction opening cutting dust that is produced proximate the opposing cut edges of the cut piece;
a rotating portion configured to move the first suction opening and the second suction opening into contact with the cut piece after the at least two cutting members are moved away from the separator; and
a driving mechanism configured to move the first suction unit away from the separator to move the cut piece away from the separator while leaving the second suction unit in contact with the cut piece.

2. The separator cutting apparatus for an electrical device as claimed in claim 1 , wherein the suction member further comprises a third suction unit with the first suction unit provided between the second suction unit and the third suction unit so as to sandwich the first suction unit, the second suction unit and the third suction unit spaced to correspond to the opposing cut edges of the cut piece.

3. The separator cutting apparatus for an electrical device as claimed in claim 1 , wherein each of the at least two cutting members is formed with an aperture in a side surface portion thereof and a hollow base portion thereof opposing a blade end and opened to the aperture.

4. The separator cutting apparatus for an electrical device as claimed in claim 3 , further comprising a blowing member disposed adjacent each of the at least two cutting members for blowing air in a direction of the side surface portion of a respective cutting member so that cutting dust may be blown through the aperture in the side surface portion and into the hollow base portion.
