Problems solved by technology
[0005] In the method shown in Patent Document 1, interference can be checked two-dimensionally based on the outline of the planar projected figure of the component. It also moves in the X and Y directions, that is, sometimes it moves obliquely. Therefore, only checking the interference with two-dimensional data will not be able to accurately detect the interference between the nozzle and the mounted component during the movement of the nozzle.

Embodiment Construction
[0038] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0039] figure 1 and figure 2 A surface mounter (hereinafter referred to as a mounter) to which the present invention is applied is schematically shown. As shown in the above figure, the base 1 of the mounter is provided with a conveyor 2 for conveying substrates. The substrate 3 is conveyed on the conveyor 2 and can be stopped at a predetermined mounting work position.
[0040]Component supply units 4 are provided on both sides of the conveyor belt 2 . The supply unit 4 is provided with a plurality of rows of tape feeders 4a. Each tape feeder 4a has a tape (tape) that can be guided from a reel, and holds small chip chips such as ICs, transistors, and capacitors at predetermined intervals, and passes through the head unit described later. 6 Components can be fed out intermittently while taking out components.
[0041] Above the above-mentioned base 1, a head unit 6...

The present invention relates to a surface-mounting machine, which has a three-dimensional data storage 33a storing three-dimensional data of the shape of a used suction nozzle and the shape of each part loaded on the substrate, and a mounting data storage 33b storing preset part loading places and mounting data containing a loading sequence. The surface mounting machine further has an arithmeticmeans 34 arithmetically operating the moving locus of the suction nozzle on the basis of the part loading places and the loading sequence; and an interference discriminating means 35 discriminating the presence of interference among the suction nozzle and the previously loaded part on the substrate on the basis of the three-dimensional data of the shape of the suction nozzle and the shape of the part and the moving locus. The invention can accurately discriminate the interference state of a suction nozzle loading a part on a substrate and a loaded part in a surface-mounting machine.
Description
technical field [0001] The present invention relates to an interference detection method and an interference detection device for judging whether or not interference occurs between a suction nozzle and a mounted component when electronic components are mounted on a substrate by a suction nozzle for a surface mounting machine for mounting electronic components such as ICs on a substrate , and a surface mounter on which the interference detection device is installed. Background technique [0002] In a known surface mounter, electronic components such as ICs are picked up from a component supply unit by a movable mounting head provided with a suction nozzle, and are transported to a predetermined position on a substrate for component mounting. In this type of surface mounter, a plurality of components are sequentially mounted on a substrate according to a predetermined mounting sequence and mounting process. [0003] However, in recent years, due to downsizing of substrates on...
