A transfer pathway of mounting headsin a component-mounting round during which the mounting headmoves back and forth between a component feeding unitand a substrate conveyance mechanismis derived by a transfer pathway calculation unitfor each component-mounting round from mounting program data. On the basis of data pertaining to the thus-derived transfer pathway, image data output from a line sensor camera assigned to a head transfer range segment that the transfer pathway of the mounting headcrosses in each of component-mounting rounds are selected and captured by an image selection processing unit. The image data output from the line sensor camera whose focusing point substantially matches the imaging target can be used for detecting whether or not a component still exists.

Component mounting apparatus and component detection method

A transfer pathway of a mounting headin a component-mounting round during which the mounting headmoves back and forth between a component feeding unitand a substrate conveyance mechanismis derived by a transfer pathway calculation unitfor each component-mounting round from mounting program data. A focusing processing unitcontrols an optical system focusing mechanism, thereby matching a focusing point of a line sensor cameraachieved during imaging operation to the transfer pathway of the mounting headbased on data pertaining to the derived transfer pathway. Further, an optical system zooming mechanismadjusts an imaging range according to the focusing point. Accordingly, even when a long substrateis taken as an object, it is possible to detect with high precision whether or not a component exists on the pickup nozzleof the mounting head

An image generation method for distinguishing a shape of a component includes: a color image taking step (S) of taking an image of the component in color, and a conversion step (S, S) of converting the color image taken in the color image taking step (S) into a black-and-white grayscale image in which the shape of the component is shown in black-and-white grayscale.

Method of generating image of component

An apparatus has a holder that receives a component from a component supply and then places the component on a substrate. In operation, it is determined whether the holder would make an interference with another component already mounted on the substrate. If this judgement is affirmative, mounting of the component held by the holder is prohibited. If, on the other hand, this judgement is negative, the component held by the holder is mounted onto the substrate.

Adjustment of image pickup conditions through alternative selection of two cameras different in resolution, adjustment of image lightness of a to-be-recognized component based on component information of the component, and performing control allows an image of the component to be picked up by either one of the cameras under the image pickup conditions.

Method and apparatus for component recognition

In an electronic component mounting method and apparatus, an electronic component is taken out from an electronic component feed position, a posture of the component is detected, and the component is mounted on a board based on a detected result. The method includes acquiring image data with a camera of the component from the feed position, processing acquired image data with a plurality of algorithms for detecting postures of components, and detecting a posture of the component.

Mounting electronic component method and apparatus

An electronic component mounting apparatus ( ) includes a device for illuminating a mark ( ) on a printed circuit board ( ) for recognition. The illumination device ( ) includes a light path adjustable member ( ). This light path adjustable member ( ) is disposed between an illumination source unit ( ) and the object ( ) to be illuminated. At least one of the light incidence side and the emission side of the light path adjustable member ( ) is divided into a plurality of subareas ( ), ( ), ( ), each having a different index of refraction. Each of the subareas ( ), ( ), ( ) emits light at a respective different index of refraction. The emitted light can be collected on a specific area containing the object ( ), and appropriate illumination light can thus be emitted to the object ( ).

Electronic component mounting apparatus

A visual recognition apparatus of the invention can acquire an image exclusive of a background of a subject of image processing, thereby rendering the image of the subject fit for the image processing. More specifically, a mirror-surfaced collar covering a retainer has a specified configuration and a specified positional relationship with a lighting element and a camera such that a light from the lighting element toward the retainer is reflected by the mirror-surfaced collar for deviation from a light path to enter the camera.
