Component mounting apparatus, illuminating apparatus used in imaging and illuminating method
View Patent ↗A component mounting apparatus, an illuminating apparatus used in imaging in the component mounting apparatus and an illuminating method are provided which can support various recognition objects and can meet the requirement of downsizing by reducing the occupied space. In the component mounting apparatus which performs an operation for mounting a component on a board ( 3 ), when illumination light is irradiated to the board ( 3 ) at the time of imaging with a board recognition camera ( 12 ), and when the illumination light is irradiated from a light emitting panel ( 15 ) which is formed by laminating a light source portion ( 13 ) and a color liquid crystal panel ( 14 ) and in which a plurality of light emitting portions whose light emission states can be individually changed are orderly arranged, the irradiation range of the illumination light which is irradiated from the respective light emitting portions are made to be changed on the basis of the imaging object. Therefore, while the imaging can be made on conditions suitably corresponding to various recognition objects, the requirement of downsizing can be met by reducing the occupied space of an illuminating portion ( 20 ).
1. A component mounting apparatus which performs an operation for mounting a component on a board which is held by a board holding portion, comprising:
an operation performing mechanism which performs an operation for mounting the component on the board;
an imaging portion which captures an image of a mark provided on the component or the board or an image of a body of the component;
an illuminating portion which irradiates an illumination light to the component or the board when the imaging portion captures the image of the mark or the image of the body of the component; and
a recognition portion which performs a recognition process to recognize the image of the mark or the image of the body of the component;
wherein the illuminating portion includes a light emitting panel having a plurality of light emitting portions orderly arranged, and light emission control portion which individually controls the light emitting portions to change an irradiated range of the illumination light irradiated from the light emitting panel in accordance with a type of the mark or the component, wherein a light emission state of each of the plurality of light emitting portions is individually variable.
2. The component mounting apparatus according to claim 1 , wherein changing the irradiated range of the illumination light provides a plurality of illumination patterns of different irradiated areas and different non-irradiated areas.
3. An illuminating apparatus used in imaging, which performs an operation for mounting a component on a board held by a board holding portion, comprising:
an operation performing mechanism which performs an operation for mounting the component on the board;
an imaging portion which captures an image of a mark provided on the component or the board or an image of a body of the component;
a recognition portion which performs a recognition process to recognize the image of the mark or the image of the body of the component, which irradiates an illumination light to the component or the board when the imaging portion captures the image of the mark or the image of the body of the component; and
a light emitting panel having a plurality of light emitting portions orderly arranged, and light emission control portion which individually controls the light emitting portions to change an irradiated range of the illumination light irradiated from the light emitting panel in accordance with a type of the mark or the component, wherein a light emission state of each of the plurality of light emitting portions is individually variable.
4. The illuminating apparatus according to claim 3 , wherein changing the irradiated range of the illumination light provides a plurality of illumination patterns of different irradiated areas and different non-irradiated areas.
5. An illuminating method used in a component mounting apparatus which performs an operation for mounting a component on a board which is held by a board holding portion and comprising an operation performing mechanism which performs an operation for mounting the component on the board, an imaging portion which captures an image of a mark that is provided on the component or the board or an image of a body of the component, and a recognition portion which performs a recognition process to recognize the image of the mark or the body of the component, which irradiates an illumination light to the component or the board when the imaging portion captures the image of the mark or the image of the body of the component, comprising
changing an irradiated ranges of the illumination light irradiated from a light emitting panel having a plurality of light emitting portions orderly arranged in accordance with a type of the mark or the component, wherein a light emission state of each of the plurality of light emitting portions is individually variable.
6. The illuminating method according to claim 5 , wherein changing the irradiated range of the illumination light provides a plurality of illumination patterns of different irradiated areas and different non-irradiated areas.
