Abstract

Image data of various kinds of components and component text data required for mounting of components, e.g., shapes, dimensions, packing forms, colors, and the like of the components, are stored in a storage medium in a manner to be read out as part of a component electronic catalog. The storage medium is used to make a search for components on a screen and automatically read out necessary component text data. The component electronic catalog can be used not only to search for components on a screen, similar to a conventional component electronic catalog, but to automatically read out component text data so as to automatically form mounting data for components to be mounted which are selected through the screen search.

Claims2

Dependent claims

A method for performing a component recognition operation, the method comprising:

while using a component electronic catalog storing component text data of a plurality of components to be mounted, the component text data including shapes, dimensions, and weights of the plurality of components,
selecting one of the plurality of components from the component electronic catalog;
reading out from the catalog the component text data corresponding to the selected component;
selecting one of a plurality of nozzles for sucking the selected component based on component text data read from the catalog corresponding to the selected component;
and
comparing a size of a suction face of the selected nozzle with a dimension of the selected component to be sucked by the selected nozzle,
wherein, if the size of the suction face of the selected nozzle is larger than the dimension of the selected component, then performing a reflection type of component recognition operation for recognizing a posture of the selected component to be sucked by the selected nozzle with respect to the selected nozzle by illuminating the selected component from below the selected component and then receiving a light reflected by a bottom surface of the selected component, and
wherein, if the size of the suction face of the selected nozzle is smaller than the dimension of the selected component, then performing a transmission type of component recognition operation for recognizing a posture of the selected component to be sucked by the selected nozzle with respect to the selected nozzle by illuminating the selected component from above to below the selected component and then receiving a light passed through a periphery of the selected component.

A method for performing a component recognition operation, the method comprising:

deciding whether or not a component mounting apparatus has a reflection type illumination device and/or a transmission type illuminating device;
wherein, if said deciding indicates that the component mounting apparatus has both of the reflection type illumination device and the transmission type illuminating device, performing operations as follows:
while using a component electronic catalog storing component text data of a plurality of components to be mounted, the component text data including shapes, dimensions, and weights of the plurality of components,
selecting one of the plurality of components from the component electronic catalog;
reading out from the catalog the component text data corresponding to the selected component;
selecting one of a plurality of nozzles for sucking the selected component based on the component text data read from the catalog corresponding to the selected component;
and
comparing a size of a suction face of the selected nozzle with a dimension of the selected component to be sucked by the selected nozzle,
wherein, if the size of the suction face of the selected nozzle is larger than the dimension of the selected component, then performing a reflection type of component recognition operation for recognizing a posture of the selected component to be sucked by the selected nozzle with respect to the selected nozzle by illuminating the selected component from below the selected component and then receiving a light reflected by a bottom surface of the selected component,
wherein, if the size of the suction face of the selected nozzle is smaller than the dimension of the selected component, then performing a transmission type of component recognition operation for recognizing a posture of the selected component to be sucked by the selected nozzle with respect to the selected nozzle by illuminating the selected component from above to below the selected component and then receiving a light passed through a periphery of the selected component;
wherein, if said deciding indicates that the component mounting apparatus has only the reflection type illumination device, then performing the reflection type of component recognition operation for mounting the selected;
and
wherein, if said deciding indicates that the component mounting apparatus has only the transmission type illumination device, selecting a nozzle with a suction face that is smaller than the dimension of the selected component and then performing the transmission type component recognition operation.
