Abstract

An electronic component handler includes a region where an electronic component placing unit on which an electronic component is placed is capable of being disposed. A transport unit includes a first hand and a second hand for holding and transporting the electronic component. A light irradiation unit is capable of emitting light toward the electronic component placing unit and is capable of adjusting an emitting direction of the light. A capturing unit is capable of capturing an image of the electronic component placing unit irradiated with the light via a space between the first hand and the second hand. A control unit performs determination processing about the presence or absence of the electronic component in the electronic component placing unit based on the image captured by the capturing unit.

First claim

What is claimed is:

1. An electronic component handler comprising:
a region for accommodating an electronic component support on which an electronic component is placed;
a transporter having a first hand and a second hand for holding and transporting the electronic component;
a light source which is configured to emit light toward the electronic component support and configured to adjust an emitting direction of the light;
a camera which is configured to capture an image of the electronic component support, the electronic component support being irradiated with the light via a space between the first hand and the second hand;
a display which displays the image captured by the camera; and
a controller which controls the transporter, the light source, and the camera, and is configured to determine a presence or absence of the electronic component on the electronic component support based on the image captured by the camera,
wherein the camera captures a first image when the transporter is positioned at a first position and captures a second image when the transporter is positioned at a second position different from the first position, and
wherein the controller displays the first image and the second image together on the display.

2. The electronic component handler according to claim 1 ,
wherein the controller displays a composite image obtained by composing the first image and the second image on the display.

3. The electronic component handler according to claim 2 ,
wherein the light has an elongated irradiation shape, and
wherein the composite image is a combination of the first image and the second image along a longitudinal direction of the elongated irradiation shape in the first image and the second image.

4. The electronic component handler according to claim 1 ,
wherein the controller displays the first image and the second image separately side by side on the display.

5. The electronic component handler according to claim 1 ,
wherein, in a case where the same part of the electronic component support is taken in the first image and the second image, the controller removes the same part from one of the first image or the second image and displays the images.

6. The electronic component handler according to claim 1 ,
wherein, in a case where the same part of the electronic component support is taken in the first image and the second image, the controller removes the same part from both of the first image and the second image and displays the images.

7. The electronic component handler according to claim 1 ,
wherein the electronic component support includes a plurality of recesses arranged in rows and columns to accommodate the electronic component therein, and
wherein the first image and the second image are images respectively obtained by capturing different rows out of the rows.

8. The electronic component handler according to claim 1 ,
wherein the controller displays the first and second images on the display prior to the controller determining the presence or absence of the electronic component.

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

10. An electronic component tester comprising:
a region for accommodating an electronic component support on which an electronic component is placed;
a transporter having a first hand and a second hand for holding and transporting the electronic component;
a light source which configured to emit light toward the electronic component support and configured to adjust an emitting direction of the light;
a camera which is configured to capture an image of the electronic component support, the electronic support being irradiated with the light via a space between the first hand and the second hand;
a display which displays the image captured by the camera; and
a controller which controls the transporter, the light source, and the camera, and is configured to determine a presence or absence of the electronic component on the electronic component support based on the image captured by the camera,
wherein the camera captures a first image when the transporter is positioned at a first position and captures a second image when the transporter is positioned at a second position different from the first position,
wherein the controller displays the first image and the second image together on the display, and
wherein the electronic component support is a tester which is configured to test the electronic component placed thereon.
