Title:
COMPONENT POSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/176463
Kind Code:
A1
Abstract:
A component position detection device (400) for accurately measuring the position of a component (P) that has been suction-attached to a suction-attachment nozzle (20) comprises: a first lighting (210) that emits light of a first frequency from the tip-end side toward the rear-end side of the suction-attachment nozzle (20); a reflecting plate (230) that reflects the light emitted by the first lighting (210) from the rear-end side toward the front-end side of the suction-attachment nozzle (20); and a first camera (220) that receives the light of the first frequency that has been reflected by the reflecting plate (230). The reflecting plate (230) is coated with, or contains, a light-reflective pigment that reflects the light of the first frequency. Alternatively, a multilayer film in which each layer has a thickness of an integer multiple of 1/4 the wavelength of the light of the first lighting (210) is deposited on the reflecting plate (230).
