Abstract

A vacuum tweezer includes: a tweezer body including a suction distal end portion that performs vacuum suction of an object to be suctioned; and a light source causing a beam to be condensed at a position on an extension of the suction distal end portion on which a vacuum suction force acts.

Claims (14)

1. A vacuum apparatus comprising:

a body including a suction distal end portion that performs vacuum suction of an object to be suctioned; and

a laser light source radiating a light beam from a location on the body, the light beam being condensed to a minimum diameter at a position extended from the suction distal end portion, the position being a location on which a vacuum suction force from the suction distal end portion acts, the position being a non-contact location of the suction distal end portion with the object.

2. The vacuum apparatus of claim 1 , wherein the light source is placed inside the suction distal end portion and the light beam is radiated from a distal end port of the suction distal end portion.

3. A vacuum apparatus comprising:

a body including a suction distal end portion that performs vacuum suction of an object to be suctioned; and

a laser light source positioned on the body and outputting a plurality of beams, the plurality of beams positioned to cause the plurality of beams to cross each other at a position extended from the suction distal end portion, the position being a location on which a vacuum suction force from the suction distal end portion acts on the object, the position being a non-contact location of the suction distal end portion with the object.

4. The vacuum apparatus of claim 3 , wherein the plurality of beams are three beams.

5. The vacuum apparatus of claim 3 , wherein the plurality of beams have mutually different colors.

6. A vacuum apparatus comprising:

a body including a suction distal end portion that performs vacuum suction of an object to be suctioned; and

a laser light source outputting a plurality of beams from a location on the body, the plurality of beams positioned to overlap at a spaced distance from the suction distal end portion, the spaced distance being a distance at which a vacuum suction force from the suction distal end portion acts, the position being a non-contact location of the suction distal end portion with the object.

7. The vacuum apparatus of claim 6 , wherein the plurality of beams are three beams.

8. The vacuum apparatus of claim 6 , wherein the plurality of beams have mutually different colors.
