Abstract
A mounting machine which mounts one or more components on a substrate includes: a mounting head which has a fiducial mark, holds the component, and moves the component onto the substrate; an imaging section which images the mounting head; setting means for setting, out of image data of the fiducial mark and component held by the moving mounting head captured by the imaging section, a processing region containing the component, based on the position of the fiducial mark; and detection means for detecting a state of the component which is held by the mounting head by processing the image data of the set processing region.
Claims12
A mounting machine, the mounting machine comprising:
- a mounting head which includes a fiducial mark;
- a suction nozzle attached to the mounting head, configured to hold a component, and move the component onto a substrate;
- a camera which captures a reference image and a component image, the reference image including the fiducial mark and the suction nozzle not holding the component, the component image including the component and the fiducial mark;
- and
- a microprocessor configured to
- detect a position of the fiducial mark;
- set a processing region for the component image based on the detected position of the fiducial mark and the reference image;
- and
- detect a positional shifting amount or a suction angle of the component based on the set processing region.
A component detection method of a mounting machine, the mounting machine including a mounting head which has a fiducial mark, the component detection method comprising:
- capturing, by a camera, a reference image and a component image, the reference image including the fiducial mark and a suction nozzle not holding a component, the component image including the component and the fiducial mark;
- detecting, by a microprocessor, a position of the fiducial mark;
- setting, by the microprocessor, a processing region for the component image based on the detected position of the fiducial mark and the reference image;
- and
- detecting, by the microprocessor, a positional shifting amount or a suction angle of the component based on the set processing region.
A mounting method of a mounting machine, the mounting machine including a mounting head which has a fiducial mark, the mounting method comprising:
- capturing, by a camera, a reference image and a component image, the reference image including the fiducial mark and a suction nozzle not holding a component, the component image including the component and the fiducial mark;
- detecting, by a microprocessor, a position of the fiducial mark;
- setting, by the microprocessor, a processing region for the component image based on the detected position of the fiducial mark and the reference image;
- detecting, by the microprocessor, a positional shifting amount or a suction angle of the component based on the set processing region;
- rotating a suction nozzle holder to correct the detected positional shifting amount or the suction angle of the component, the suction nozzle being mounted on the suction nozzle holder;
- and
- mounting the component with the corrected positional shifting amount or suction angle onto a substrate.
