US 6,178,833 B2 · Electronic parts loading device

Abstract

Disclosed is an electronic parts loading device comprising a head unit on which a operating means, such as a loading mechanism for loading electronic parts on a printed circuit board or an adhesive spread mechanism for spreading adhesive on a place of the printed circuit board where the electronic parts are to be mounted, is mounted; driving means for moving the operating means toward or away from the printed circuit board; measuring means for measuring a distance from the head unit to a loading place of the printed circuit board, the measuring means being mounted on the head unit; and control means for optimally controlling the movement of the operating means in response to data measured by the measuring means whenever the operating means performs a working.

Dependent claims

An electronic part mounting device, comprising:

a head unit;
an operating means, mounted on the head unit and rotatable about a central axis from a rotation reference position, for performing an operation on a printed circuit board, the operating means having a working device mounted thereon at a location separated from the central axis by a radial offset and separated from the central axis with respect to the rotation reference by an angular offset;
drive means for positioning the operating means to a specified location with respect to the printed circuit board;
detecting means for detecting the presence of the working device;
calculating means for calculating the radial and angular offsets;
and
control means for positioning the working device to a desired location with respect to the printed circuit board by operating the drive means to position the operating means at the desired location, corrected by the calculated radial and angular offsets.
