Abstract
A mounting apparatus for mounting an electronic component on a circuit board, which apparatus has a pickup head with a suction nozzle arranged to be movable on a horizontal plane and further movable vertically with respect to the horizontal plane, thereby picking up and carrying the electronic component to the circuit board. The apparatus is also equipped with a laser monitoring section for monitoring the electronic component picked up by the pickup head. The laser monitoring section includes a laser illuminating device for emitting a laser light beam to the electronic component placed at a monitoring position and for receiving light reflected from the electronic component to obtain information indicative of a state of the electronic component. The laser illuminating device is encased within a cover device arranged to be openable and closable to receive the picked-up electronic component and cover the electronic component when reaching the monitoring position. The cover device has a dome-like configuration and comprises two portions symmetrically arranged to be movable horizontally to be separated from each other and brought close to each other so that the dome-like cover device is openable and closable. This arrangement can prevent the laser light beam from the laser illuminating device from damaging the apparatus operator.
