Abstract

A foreign body removing device includes a foreign body removing tool for removing a foreign body that has adhered to a surface of a workpiece. This foreign body removing tool includes: a grip to be grasped by a worker; a blade that contacts the foreign body; and an airflow delivering portion for delivering compressed gas that has been supplied from a compressed gas supply source, as an airflow contacting the blade.

First claim

What is claimed is:

1. A foreign body removing device comprising:
a compressed gas supply source;
a foreign body removing tool configured to remove a foreign body that has adhered to a surface of a workpiece,
wherein the foreign body removing tool comprises:
a grip configured to be gripped by a worker,
a blade that extends from the grip and that is configured to contact the foreign body, and
an airflow delivering portion that includes a discharge hole configured to deliver compressed gas that has been supplied from the compressed gas supply source, as an airflow contacting the blade;

a base configured to support the workpiece, wherein on an inside of the base, there is formed a flow passage that is configured to allow second compressed gas from the compressed gas supply source to flow, and the flow passage opens into a hollow portion that is formed between the base and the workpiece when the workpiece is supported upon the base; and
two partitioning portions, including a first partitioning portion and a second partitioning portion, that are walls that form an inner chamber between the first partitioning portion and the second partitioning portion within the hollow portion,

wherein the flow passage opens in the inner chamber.

2. The foreign body removing device according to claim 1 , wherein the blade has a combtooth-shaped cutting portion.

3. The foreign body removing device according to claim 1 , wherein the blade has a sawtooth-shaped cutting portion.

4. The foreign body removing device according to claim 3 , wherein the airflow delivering portion supplies the airflow to the cutting portion.

5. The foreign body removing device according to claim 1 , further comprising an intercepting member that includes a shielding surface and is configured to capture the foreign body that has been blown by the airflow after separating from the surface of the workpiece.

6. The foreign body removing device according to claim 5 , wherein the intercepting member is detachably attached to the base in a manner that a position of the intercepting member is changeable.

7. The foreign body removing device according to claim 1 , wherein the foreign body removing device is configured to remove, as the foreign body, dross generated by laser processing.
