DETAILED DESCRIPTION OF THE INVENTION
1 is a perspective view of the panel member, FIG. 2 is a side view situation in FIG. 1, FIG. 3 is a front view situation in FIG. 1, and FIG. 4 is a view of a panel member according to an embodiment of the present invention. The conceptual situation of a device implementing the manufacturing method is shown.
[0011]
As shown in FIGS. 1 to 3, the panel member 1 has a rectangular shape having a plane (a crossing surface) perpendicular to the flat panel panels 2a and 2b between a pair of flat panel panels 2a and 2b (for example, a thickness of 2 mm to 3 mm). A plurality of rib plates 3 having a shape (for example, a width of 50 mm to 60 mm) are provided, and the rib plates 3 are joined between the flat panel panels 2a and 2b. For the joining of the rib plate 3, laser welding is performed simultaneously from both the front surface side of the flat panel 2a, 2b (the side where the rib plate 3 is not disposed) with the rib plate 3 disposed between the flat panel 2a, 2b. Applied.
[0012]
That is, a plurality of pairs of gripping jigs 4 for gripping the end portion of the rib plate 3 and pulling in the longitudinal direction (direction of arrow A in FIGS. 1 and 2) are provided, and the rib plate 3 is provided on the surface of one flat panel 2b. A plurality of rib plates 3 are pulled and urged by the holding jig 4 in the longitudinal direction. In this state, the other flat panel 2a is placed on the rib plate 3, and the flat panel 2a, 2b is pressed by the pressure roller 5 from both sides before and after the laser processing head 6 so that the two laser processing heads 6 are mounted. It is moved and welding of a welded part is simultaneously performed from both surfaces of the flat panel 2a, 2b.
[0013]
The flat panels 2a and 2b can be pressed by a pressure panel having a weld line opening instead of the pressure roller 5 as a whole. Further, the laser processing head 6 may be moved while pulling and urging the flat panel 2a, 2b in a direction orthogonal to the moving direction of the laser processing head 6 (in the direction of arrow B in FIG. 3) during welding. Further, it is also possible to perform welding by arranging the flat panels 2a and 2b vertically and moving the laser processing head 6 up and down.
[0014]
Accordingly, since the welded portions are welded simultaneously from both sides of the flat panel 2a, 2b in a state where the flat panel 2a, 2b is pressed by the pressure roller 5, the bending of the flat panel 2a, 2b is removed and the deformation is suppressed. It becomes possible to manufacture the panel member 1 efficiently.
[0015]
As shown in FIG. 4, the position of the pair of gripping jigs 4 that pull and bias the rib plate 3 in the longitudinal direction is detected by the detection sensor 7, and information of the detection sensor 7 is input to the control device 8. In the control device 8, the position of the welding line 9 (see FIG. 1) as a target position is derived based on the information of the detection sensor 7 (position information of the pair of gripping jigs 4). From the control device 8, a movement command is output to the moving means 10 of the laser processing head 6 and a drive command is output to the laser oscillator 11 based on the information on the derived welding line 9. As a result, the laser processing head 6 can be moved along the welding line 9 to accurately irradiate the welding line 9 with the laser beam.
[0016]
Therefore, by detecting the gripping jig 4 by the detection sensor 7, the welding line 9 can be accurately grasped, and the laser processing head 6 is reliably moved along the welding line 9 to perform accurate welding. Is possible. For this reason, the rib plate 3 can be reliably joined to the flat panels 2a and 2b without forming a margin for welding by forming the rib plate 3 like a U-shaped cross section.
[0017]
In welding, as long as the rib plate 3 can be joined from the surface side of the flat panels 2a and 2b, an apparatus such as electric welding can be applied in addition to laser welding. In the embodiment described above, the laser processing head 6 is moved along the welding line 9. However, the laser processing head 6 is provided in accordance with the number of welding lines, and the laser processing head 6 is fixed. It is also possible to perform welding by moving the panel member 1 with a table or the like.
[0018]
As a method for manufacturing the panel member 1, as shown in FIG. 5, the rib plate 3 is gripped by the gripping jig 4, pulled in the longitudinal direction and installed on the surface plate 21, and the flat panel 2a is ribbed. It arrange | positions on the board 3, it welds in the state which pressed the flat panel 2a to the rib board 3, it reverses, another flat panel (illustration omitted) is arrange | positioned on the rib board 3, and another flat panel is attached. By performing welding in a state where the rib plate 3 is pressed, the rib plate 3 can be joined between the pair of flat panel panels.
