よる部品固定方法。1. A winding step of winding a band around each winding position of a plurality of parts attached to an assembly by a band winding device, and a laser for irradiating overlapping portions at both ends of the band from a laser irradiation head. In a method of fixing a component, which comprises a welding process of welding with a beam, an object to be assembled is sequentially conveyed to a plurality of work stations in which band wrapping devices are respectively arranged, and a predetermined component is tightened at each work station. The band winding process is performed for each location, and multiple band winding devices arranged at these work stations are used to convey the objects to be assembled so that the number of laser irradiation heads is less than the number of band winding devices. The groups are divided into at least two groups, one in the front and one in the rear, and each group is provided with a laser irradiation head for one unit. Sequentially moved so as to perform a welding process in a position that matches the device with the band winding belonging to,
Further, the movement of one laser irradiation head and the movement of the other laser irradiation head are alternately performed so that the laser beam from one laser oscillator is commonly guided to the other laser irradiation head during the movement of one laser irradiation head. A method of fixing a component using a band, which is characterized in that a welding process is performed by using a band.

特徴とするバンドによる部品固定装置。2. A component provided with a band winding device for winding a band around each winding position of a plurality of components inserted and attached to an object to be assembled, and a laser irradiation head for irradiating a laser beam to overlapping portions at both ends of the band. In the fixing device, a plurality of work stations for sequentially transporting the objects to be assembled are provided, and band wrapping devices corresponding to the winding positions of predetermined parts are arranged at the respective work stations, and the number of laser irradiation heads is increased. The plurality of band winding devices arranged in these work stations are grouped into at least two groups, ie, a front position and a rear position in the conveying direction of the object to be assembled so that the number of band winding devices is smaller than that of the band winding devices. One laser irradiation head is provided for each group, and the laser irradiation heads are sequentially moved independently of each other to positions corresponding to each band winding device belonging to the corresponding group. Moving means, one common laser oscillator, switching means for selectively directing a laser beam from the laser oscillator to each laser irradiation head, and controlling the moving means so that each laser irradiation head is moved alternately And a control means for controlling the switching means so that the laser beam is guided to the other laser irradiation head while the one laser irradiation head is moving, and a component fixing device using a band.
