Abstract:
1. A head assembly for a chip mounter comprising: a nozzle module disposed above a printed circuit board (PCB) and configured to suck and move an electronic component to mount the electronic component on the PCB along a moving path of a lift device of the nozzle module; and a component recognition module electrically connected to the nozzle module and configured to recognize presence of the electronic component, a distance between the PCB and the nozzle module when the electronic component is at a first position located above the PCB and on the moving path, and alignment of the electronic component when the electronic component is at a second position located higher in height than the first position and located on the moving path, wherein the moving path is formed perpendicular to a surface where the electronic component is mounted on the PCB, wherein the nozzle module comprises: a nozzle module body; the lift device installed at the nozzle module body and configured to receive an electrical signal from an exterior to be raised and lowered along the moving path toward the PCB; a nozzle installed at a lower end of the lift device and configured to suck the electronic component; and two position sensors disposed at the first position and the second position at at least one side of the moving path, located under the nozzle module, and configured to measure at least one given moving position of the electronic component.
