    摘要： A method for manufacturing a resin molding that uses a laser beam can provide a high level of adhesion, an excellent appearance, and can include very strong welded portions. The method can include preparing a light-transmitting resin member having a protruding portion formed on a rear surface of the light-transmitting resin member and having an end surface, the protruding portion having both side surfaces having asymmetric inclination angles with respect to the normal of the end surface of the protruding portion. The method can also include arranging and pressing together the end surface of the protruding portion that is a welded region of the light-transmitting resin member, and a welded region of a corresponding light-absorbing resin member so that they are opposed to each other. A laser beam can be emitted from a laser light source to be incident on a surface of the light-transmitting resin member while the laser beam is refracted. The method can also include repeatedly irradiating the laser beam onto the welded regions to heat and fuse the entire welded regions to weld the light-transmitting resin member and the light-absorbing resin member while opposed to each other and pressed together, wherein the inclination angle of the side surface of the protruding member near the laser light source is equal to or more than a travel angle of the refracted laser beam.

    摘要： A method for manufacturing a resin molding can be provided that uses a laser beam. The method can include providing the resin molding including welded portions that can impart high level of adhesion, have excellent appearance and provide very strong bonding strength. The method can also include arranging and pressing a weld region of a light-absorbing resin member and corresponding weld region of a light-transmitting resin member that are opposed to each other, and setting a plurality of irradiation areas in the extending direction of the welded regions. The method can also include arranging a plurality of laser irradiation scanning heads corresponding to the irradiation areas. Here, the irradiation areas can include a single irradiation area which the corresponding scanning head can irradiate with the laser beam and a composite irradiation area which the adjacent scanning heads can irradiate with respective laser beams. The method can further include causing the plurality of laser beams emitted from the scanning heads to repeatedly scan the single irradiation area along a first trajectory in the extending direction of the single irradiation area and part of both the single irradiation area and the composite irradiation area along a second trajectory in the extending direction, so that the entire welded regions are heated and fused to weld the light-transmitting resin member and the light-absorbing resin member.
