The invention is directed to prevention of interference of an operation of mounting proper electronic components and improvement of usability without reduction of a manufacturing speed of printed boards. Suction states of electronic components held by suction by suction nozzles are detected by a line sensor unit. When the detection result shows that there is an improper electronic component, the improper electronic component is disposed of, and after the disposal a component recognition camera takes images of electronic components judged proper as a result of the detection and a recognition processing device performs a recognition process. When the recognition result shows that there is an improper electronic component, the improper electronic component is disposed of, and after the disposal only electronic components judged proper as a result of the recognition are mounted on a printed board.

Method of mounting electronic component

Electronic component mounting method

The invention provides an electronic component mounting apparatus which can obtain a relative vertically moving stroke of a suction nozzle and is applicable to electronic components ranging from thin to thick ones. The electronic component mounting apparatus of the invention has a suction nozzle for picking an electronic component up from a plurality of component feeding units supplying the electronic component to a component pickup position and mounting the electronic component on a printed board, where a mounting head movable along a beam can move vertically by a head vertical movement device and the suction nozzle provided on the mounting head can move vertically by a nozzle vertical movement device

Electronic component mounting apparatus

The invention provides a mounting apparatus with a beam which is free from adverse effect on its performance due to thermal distortion and misalignment of its guide rails, on which the beam for mounting operation travels. One end of the beam is rotatably supported on a slide, which moves along the guide rails. Another end of the beam is also rotatably supported on another slider through a moving element. The slider and the mounting element move along the guide rail. The moving element moves in a direction perpendicular to the guide rails.
