該部品の影像を画像入力装置に投影することができる。(Operation) In the component recognition device in the component mounting machine of the present invention,
Since a plurality of light emitting diodes (LEDs) on the lower surface side of the reflecting plate and a diffusing plate that scatters the light of each light emitting diode are combined, the illumination means provided on the support exterior body is integrally attached around the suction nozzle. It is possible to irradiate light stably and uniformly from behind the component sucked by the suction nozzle to project a shadow image of the component on the image input device.

合が発生することはない。Further, the light emitting diode of the lighting means is not likely to be deteriorated by the vibration caused by the operation of the mounting head, has a long life, is excellent in durability, and consumes less power. Therefore, the maintenance of the lighting means is easy, and the manufacturing of the lighting means is facilitated. Cost and running cost can be reduced. Further, the light emitting diode can be selected from various shapes such as a surface emitting type, which is small in size and requires a small space for installation, and generates almost no heat during lighting, which increases the degree of freedom in the shape of the lighting means. . In this way, by using a light emitting diode as the light source of the illumination means to make the back of the component brighter, the cost is reduced, vibration resistance is improved, and the degree of freedom in shape is improved compared to conventional ring light sources. It is possible to reduce power consumption and heat generation. Further, since the reflecting plate is provided behind the light emitting diode, the generated light can be effectively directed to the component, and the brightness can be improved. Further, since the light of the light emitting diode is scattered and uniformized by the diffusion plate, the image of the component can be captured in the image input device with a good contrast, and the light source is not properly arranged as in the conventional device. In such a case, the problem that the image of the part cannot be captured does not occur.
