Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple illumination light sources are placed at different positions to clearly identify recognition objects with varying surface properties, then imaging quality is improved, but the occupied space of the illuminating apparatus increases
Solution Approach 1:
The illuminating apparatus divides the illumination function into multiple independent light sources (first illumination light source and second illumination light source) that can be selectively activated. This segmentation allows the system to provide different illumination conditions for different recognition objects without requiring all light sources to be simultaneously active, thereby maintaining imaging quality while reducing the effective illumination area needed at any given time.
Solution Approach 2:
The control unit dynamically selects which illumination light source to activate based on the type of recognition object being imaged. For recognition marks, the first illumination light source is activated; for component bodies, the second illumination light source is activated. This dynamic control allows the system to adapt illumination conditions to specific imaging needs without requiring a fixed large array of simultaneously active light sources, thus reducing occupied space while maintaining imaging quality.
2Adaptability or versatility
If various illumination conditions with different irradiation ranges and color tones are provided to support various recognition objects, then adaptability is improved, but device complexity increases
Solution Approach 1:
The illuminating apparatus uses a control unit that serves multiple functions: identifying recognition objects, selecting appropriate illumination light sources, and controlling illumination conditions. This multi-functional control unit allows the system to adapt to different recognition objects (marks or component bodies) and provide appropriate illumination conditions without requiring separate dedicated illumination systems for each object type, thereby reducing overall device complexity while maintaining high adaptability.
Solution Approach 2:
The system changes illumination parameters (which light source to activate, irradiation range, and color tone) based on the type of recognition object being imaged. By dynamically adjusting these parameters rather than providing fixed separate illumination systems for each object type, the apparatus achieves high adaptability with reduced structural complexity. The control unit modifies illumination conditions in response to different imaging requirements.

AI summary
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).
