Abstract

An electronic component handler includes: a transport unit which transports an electronic component; a region where an electronic component placement unit on which the electronic component is placed is capable of being disposed; a light irradiation unit which is capable of emitting light and capable of adjusting an irradiation direction of the light with respect to the electronic component placement unit; a processing unit which performs determination processing about the presence or absence of the electronic component in the electronic component placement unit based on at least one of a projection shape and an irradiation position of the light projected to the electronic component placement unit; and a display unit which displays an image having the projection shape.

First claim

What is claimed is:

1. An electronic component handler comprising:
a transporter which transports an electronic component;
a test region configured to accommodate an electronic component support having a plurality of recessed pockets in which the electronic component is placed, each of the plurality of recessed pockets having a longitudinal axis aligned with a longitudinal axis of the electronic component support;
a plurality of light sources vertically aligned perpendicular to a face of the test region and differently oriented with respect to the plurality of recessed pockets, each of the plurality of light sources being configured to emit light at one of the plurality of recessed pockets and being configured to adjust an irradiation direction of the light with respect to the one of the plurality of recessed pockets, the plurality of light sources being vertically aligned along a light source axis that intersects and is orthogonal to the longitudinal axes of each of the plurality of recessed pockets;
a processor configured to determine a presence or absence of the electronic component on the electronic component support based on at least one of a projection shape and an irradiation position of the light projected toward the electronic component support; and
a display which displays an image having the projection shape;
wherein the electronic component support comprises an electronic component placement unit.

2. The electronic component handler according to claim 1 ,
wherein the display is configured to display a projection position of the light and an image obtained by capturing the electronic component support.

3. The electronic component handler according to claim 1 , further comprising:
a notifier configured to notify that the irradiation position is at a predetermined position.

4. The electronic component handler according to claim 3 ,
wherein the electronic component support has a recess in which the electronic component is accommodated, and
wherein the notifier makes a first notification when the irradiation position is in a first region including the recess and makes a second notification when the irradiation position is in a second region which is outside of the first region and on the electronic component support.

5. The electronic component handler according to claim 4 ,
wherein the notifier emits sound, and
wherein the first notification and the second notification are different sounds.

6. The electronic component handler according to claim 4 ,
wherein the notifier makes a third notification when the irradiation position is in a third region outside of the electronic component support.

7. The electronic component handler according to claim 1 ,
wherein the adjustment of the irradiation direction includes adjusting at least one of a height of the light source in a perpendicular direction relative to the electronic component support and an angle of the light source with respect to the perpendicular direction.

8. The electronic component handler according to claim 1 ,
wherein the projection shape is linear, and
wherein a linear center line in a width direction is the irradiation position.

9. The electronic component handler according to claim 1 ,
wherein the processor is configured to adjust the irradiation direction of the light with respect to the electronic component support prior to determining the presence or absence of the electronic component on the electronic component support.

10. The electronic component handler according to claim 1 ,
wherein the electronic component support is a tester which is configured to test the electronic component placed thereon.

11. An electronic component handler comprising:
a transporter which transports an electronic component;
a test region configured to accommodate an electronic component support having a plurality of recessed pockets in which the electronic component is placed, each of the plurality of recessed pockets having a longitudinal axis aligned with a longitudinal axis of the electronic component support;
a plurality of light sources vertically aligned perpendicular to a face of the test region and differently oriented with respect to the plurality of recessed pockets, each of the plurality of light sources being configured to emit light at one of the plurality of recessed pockets and being configured to adjust an irradiation direction of the light with respect to the one of the plurality of recessed pockets, the plurality of light sources being vertically aligned along a light source axis that intersects and is orthogonal to the longitudinal axes of each of the plurality of recessed pockets;
a processor configured to determine a presence or absence of the electronic component on the electronic component support based on at least one of a projection shape and an irradiation position on the electronic component support of the light projected to the electronic component support; and
a notifier configured to notify that the irradiation position is at a predetermined position;
wherein the electronic component support comprises an electronic component placement unit.

12. The electronic component handler according to claim 11 , further comprising:
a detector configured to detect the irradiation position based on a height of a first of the plurality of light sources in a perpendicular direction relative to the electronic component support and an angle of the first of the plurality of light sources with respect to the perpendicular direction.

13. An electronic component tester comprising:
a transporter which transports an electronic component;
an electronic component support having a plurality of recessed pockets in which the electronic component is placed, each of the plurality of recessed pockets having a longitudinal axis aligned with a longitudinal axis of the electronic component support;
a test region configured to accommodate the electronic component support;
a plurality of light sources vertically aligned perpendicular to a face of the test region and differently oriented with respect to the plurality of recessed pockets, each of the plurality of light sources being configured to emit light at one of the plurality of recessed pockets and being configured to adjust an irradiation direction of the light with respect to the one of the plurality of recessed pockets, the plurality of light sources being vertically aligned along a light source axis that intersects and is orthogonal to the longitudinal axes of each of the plurality of recessed pockets;
a processor configured to determine a presence or absence of the electronic component on the electronic component support based on at least one of a projection shape and an irradiation position of the light projected to the electronic component support; and
a display which displays an image having the projection shape,
wherein the electronic component support is a tester configured to test the electronic component placed thereon.
