Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination device for component recognition, and more particularly to irradiating a component adsorbed by a suction head with illumination light to make a component image incident on a recognition device such as a recognition camera. In the component recognition device configured as described above, the present invention relates to a device for irradiating the component with illumination light. 2. Description of the Related Art Conventionally, for example, in a component mounting apparatus that suctions a component from a component storage unit with a suction head and mounts the component on a wiring board or the like, a component suctioned by a suction nozzle in order to accurately mount the component at a predetermined position. A device provided with a component recognition device for recognizing the position of an object is known. As the component recognition device disclosed in, for example, Japanese Patent Application Laid-Open No. 60-28298, as shown in FIG. A back plate 13 is provided, and illumination light is projected from a lower side position on the back plate 13 at a component recognition position by a lighting device 14, and illumination light is emitted from the back plate 13 to a component P to illuminate the component P. The image is made incident on a recognition device 15 including a recognition camera, and the position of the component P is recognized. Problems to be Solved by the Invention However, in the above-described illumination method for the component P, when a large component such as one side of the component P having, for example, 36 mm is mounted, a large back plate 23 is required. There is a problem that the suction head 21 to which the plate 23 is attached becomes large and its moving speed is reduced, so that high-speed recognition and high-speed mounting cannot be performed. There is a problem that it is difficult to uniformly irradiate the illumination light, and it is not possible to uniformly illuminate the component P. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and has as its object to provide a lighting device for component recognition that enables uniform illumination regardless of the size of a component and does not require a large illuminator in a suction head. It is. Means for Solving the Problems In order to achieve the above object, the present invention disposes a pair of illuminators at appropriate intervals at which a suction head can pass on both sides of a predetermined component recognition position, and at least provides By making it possible to irradiate the scattered light from the lower surface, the scattered light is emitted from above the component sucked by the suction nozzle at the tip of the suction head in a state where the suction head is positioned between the pair of illumination bodies. It is characterized by having comprised. The present invention has the above-described configuration, and at the time of component recognition, the suction nozzle that has sucked the component is stopped at the component recognition position through a pair of illuminating bodies, or is passed through the component recognition position, thereby providing a pair of illuminations. The scattered light can be radiated from the back of the component with the body, and the part between the illuminators is illuminated with the scattered light via the reflector by the illuminating light from the opposite end face of the illuminator. By simply attaching a relatively small reflector to the component, it is possible to irradiate scattered light uniformly on the component regardless of the size of the component without providing another light source, and the recognition image is stable and the recognition rate is improves. Furthermore, since the suction nozzle becomes lighter and can be recognized without moving up and down, the component can be recognized by moving the suction nozzle at a high speed. Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 1 denotes a suction head, which is configured to suck and hold the component P at the tip of the suction nozzle 2 at the lower end.
The suction head 1 stops at a position immediately above the recognition device 3 such as a recognition camera while moving from the component suction position to the component mounting position, and recognizes the suction position, shape, and the like of the sucked component P. It is configured. Reference numerals 4 and 5 denote an illuminating body composed of a pair of flat indirect illuminating bodies arranged at appropriate intervals on both sides of the suction nozzle 2 when the suction head 1 stops at the recognition position of the component P. It is. The illuminators 4 and 5 are composed of a light guide 6 made of a plate-shaped transparent resin, a reflection surface 7 made of an aluminum thin plate or the like disposed on the back surface thereof, and a plurality of light guides 6 formed on one end of the light guide 6. And a light source 8 such as an LED fitted in each of the concave portions, and is arranged so that the light source 8 is located at the non-opposing end. The reflecting surface 7 is formed to have a small cross-sectional shape and irregularly reflect light, and the surface of the light guide 6 is also formed to have a satin finish to irradiate scattered light. Note that the surface of the light guide 6 may be a smooth surface instead of a satin finish. The illuminators 4 and 5 are configured to be adjustable on both sides according to the diameter of the suction head 1 that changes according to the size of the component P to be sucked. I try not to. A reflector 9 that receives illumination light emitted from the opposite end faces of the illumination bodies 4 and 5 and reflects scattered light on the tip side of the suction nozzle 2 is attached to an upper portion of the suction nozzle 2. The non-illuminated portion between the illuminating bodies 4 and 5 is illuminated with scattered light from the illuminating body. A pair of inclined reflecting surfaces 9a formed on both sides of the reflector 9 are formed as satin-like reflecting surfaces. The reflector 9 may be made of a translucent body, and may not only diffusely reflect the light on the inclined reflection surface 9a but also scatter the light incident inside and irradiate the light to the outside. In the above configuration, when the component P is mounted on the wiring board, the component P sucked and held by the suction nozzle 2 in the component supply unit is used.
When the suction position is recognized, the suction head 1 stops on the axis of the recognition device 3 as shown in FIG. here,
Illumination light from the light source 8 spreads over the entire surface of the illuminators 4 and 5 through the light guide 6 and is irregularly reflected on the reflection surface 7 to be scattered and radiated to the component P. The light radiated from the opposite end faces of the illuminators 4 and 5 is scattered by the reflector 9 and is radiated to the component P. In this way, the scattered light from the illuminators 4 and 5 and the reflector 9 is uniformly radiated over a wide area including the component P, and the position of the component P is accurately recognized. When the position recognition of the component P is completed, the suction head 1 moves as it is, and the component P is mounted at a predetermined position on the wiring board. The present invention is not limited to the above embodiments. For example, the illuminating body is exemplified by a flat indirect illuminating body. However, the illuminating body is not limited to this, and any shape can be used as long as the scattered light can be uniformly irradiated from the entire surface and the space is not large. . Further, although the above-described illuminating body has been exemplified as having an integrated light source, a separate light source may be provided. Further, in the above embodiment, the reflector has the same cross section over the same width as the entire width of the illuminator. However, in some cases, the reflector has such a width that the illumination light can be emitted only when a small component is recognized. You may. Further, in the above-described embodiment, the example in which the suction nozzle 2 is stopped when the component P is recognized is described. However, if the moving accuracy of the suction nozzle 2 is increased, the suction nozzle 2 can be recognized while moving. In the above-described embodiment, an example in which the position of the component P is recognized has been described. However, the present invention is not limited to the position recognition of the component P, but may be applied to the recognition of the shape and type of the component. According to the illumination device for component recognition of the present invention, as described above, the suction nozzle that sucks the component is passed between the pair of illuminators and stopped at the component recognition position or passed through the component recognition position. As a result, it is possible to perform component recognition by irradiating scattered light uniformly from the back of the component with a pair of illuminators and a small reflector attached to the suction nozzle, and obtain a stable recognition image regardless of the size of the component. Can be In addition, since only a small reflector needs to be attached to the suction nozzle, the suction nozzle can be reduced in size and weight and can be moved at high speed, and because it is possible to recognize components without moving the suction nozzle up and down, high-speed recognition is possible. There are effects such as becoming.
