Abstract

An electronic component handler that transports an electronic component to an electronic component placement unit on which the electronic component is placed includes: a transport unit that transports the electronic component; a light irradiation unit that irradiates the electronic component placement unit with light; and a vertical direction moving mechanism unit that has a guide that supports the light irradiation unit and guides the light irradiation unit in a vertical direction.

First claim

What is claimed is:

1. An electronic component handler that transports an electronic component to an electronic component placement unit on which the electronic component is placed, the handler comprising:
a transport unit that transports the electronic component;
a light irradiation unit that irradiates the electronic component placement unit with light; and
a vertical direction moving mechanism unit having a guide that supports the light irradiation unit and guides the light irradiation unit in a vertical direction,
wherein the vertical direction moving mechanism unit has a movement adjustment unit that adjusts a position of the light irradiation unit.

2. The electronic component handler according to claim 1 ,
wherein the vertical direction moving mechanism unit has a decelerator that decelerates moving speed of the light irradiation unit.

3. The electronic component handler according to claim 1 ,
wherein the light irradiation unit has a first laser light source that emits laser light along a first optical axis and a second laser light source that emits laser light along a second optical axis, and
wherein the handler further comprises
a first turning mechanism unit that turns the first laser light source, and
a second turning mechanism unit that turns the second laser light source.

4. An electronic component handler that transports an electronic component to an electronic component placement unit on which the electronic component is placed, the handler comprising:
a transport unit that transports the electronic component;
a light irradiation unit that irradiates the electronic component placement unit with light; and
a vertical direction moving mechanism unit having a guide that supports the light irradiation unit and guides the light irradiation unit in a vertical direction,
wherein the light irradiation unit has a first laser light source that emits laser light along a first optical axis and a second laser light source that emits laser light along a second optical axis.

5. The electronic component handler according to claim 4 ,
wherein the light irradiation unit has a support unit that supports the first laser light source and the second laser light source.

6. The electronic component handler according to claim 4 ,
wherein the vertical direction moving mechanism unit has a first support unit that supports the first laser light source and a second support unit that supports the second laser light source.

7. The electronic component handler according to claim 4 ,
wherein the first laser light source and the second laser light source are disposed in the vertical direction, and
wherein when a straight line extending in the vertical direction is assumed to be a vertical line, an angle between the second optical axis of the second laser light source and the vertical line is smaller than an angle between the first optical axis of the first laser light source and the vertical line.

8. An electronic component handler that transports an electronic component to an electronic component placement unit on which the electronic component is placed, the handler comprising:
a transport unit that transports the electronic component;
a light irradiation unit that irradiates the electronic component placement unit with light;
a vertical direction moving mechanism unit having a guide that supports the light irradiation unit and guides the light irradiation unit in a vertical direction; and
a turning mechanism unit that turns the light irradiation unit.

9. The electronic component handler according to claim 8 ,
wherein the turning mechanism unit has a decelerator that decelerates an angular speed of the light irradiation unit.
