ELECTRONIC PARTS MOUNTING DEVICE

摘要

An electronic parts mounting device which quickly detects the attitude of an electronic part held by a suction nozzle in a mounting head. A hollow shaft installed on a mounting head movable horizontally between the upper region of a parts supply and the upper region of a packaging substrate is provided with a suction nozzle (25). A light receiving element (71a) having a light receiving surface (71) remote from the suction nozzle (25) and extending at right angles with the center axis (O) thereof is installed on the mounting head. Also installed on the mounting head are a lens (74) for directing light toward the light receiving element (71a) through an electronic part (E), and a light-sources group (76) having a plurality of light sources (76a - 76h) disposed at right angles with the optical axis (P1) of the lens (74) and parallel with the light-receiving surface (71). The light sources (76a - 76h) are successively turned on and the angle of rotation of the electronic part (E) with respect to the suction nozzle (25) is detected on the basis of the size of the shadow of the electronic part (E) cast on the light-receiving element (71a).
