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

A method for detecting a condition of a nozzle member of a multi-nozzle type component mounting head, in which it is determined that a nozzle is pressed against a load cell when the difference between a measured vertical position of the nozzle and a reference positional information of the nozzle is equal to or greater than a determined value and the measured vertical position of the nozzle is at a lower level position than the reference positional information, and when it is determined that the nozzle is pressed against the load cell, measuring the output value of the load cell.

An electronic component mounting apparatus includes a beam projector for projecting a laser beam, a beam receiver which is placed in opposition to the beam projector and which receives a laser beam projected from the beam projector, a light-reception-sensitivity setting unit for adjusting light-reception sensitivity of the beam receiver, a projection-side orifice provided in the beam projector to narrow a projection spot diameter of the laser beam, and a reception-side orifice provided in the beam receiver to narrow a light-reception spot diameter, where the light-reception sensitivity of the beam receiver is improved. As a result, an electronic component mounting apparatus capable of accurately detecting height size of small components by using a relatively inexpensive photoelectric sensor can be provided.
