Abstract
A substrate working device includes a working unit that performs work on a substrate on which a component is mounted, an imager capable of imaging a correction mark for position correction, and a mark projector that projects the correction mark. The correction mark includes a first correction mark and a second correction mark. The mark projector projects the first correction mark to a first height and projects the second correction mark to a second height.
Claims19
A substrate working device comprising:
- a working unit arranged above a substrate, and configured to perform work on a substrate on which a component is mounted;
- an imager arranged separated from a correction mark for position correction, in an upward-downward direction, and configured to image the correction mark, the imager including a first imager focused at a first height and a second imager focused at a second height different from the first height;
- and
- a mark projector configured to project the correction mark, such that the correction mark includes a first correction mark and a second correction mark, the mark projector is arranged at a position where the first correction mark is projected at the first height and at a position where the second correction mark is projected at the second height, and the mark projector is configured to project the first correction mark to the first height and is configured to project the second correction mark to the second height which is different from the first height, wherein
- the mark projector includes a first projection target projected as the first correction mark, a second projection target projected as the second correction mark, and a lens unit assembly configured to project the first projection target as the first correction mark to the first height and configured to project the second projection target as the second correction mark to the second height.

A component mounting device comprising:
- a mounting head configured to mount a component on a substrate;
- an imager arranged separated from a correction mark for position correction, in an upward-downward direction, and configured to image the correction mark, the imager including a first imager focused at a first height and a second imager focused at a second height different from the first height;
- and
- a mark projector configured to project the correction mark, such that the correction mark includes a first correction mark and a second correction mark, the mark projector is arranged at a position where the first correction mark is projected at the first height and at a position where the second correction mark is projected at the second height, and the mark projector is configured to project the first correction mark to the first height and is configured to project the second correction mark to the second height which is different from the first height, wherein
- the mark projector includes a first projection target projected as the first correction mark, a second projection target projected as the second correction mark, and a lens unit assembly configured to project the first projection target as the first correction mark to the first height and configured to project the second projection target as the second correction mark to the second height.
