から抜くことができる。The present invention will be explained in detail below with reference to Examples. FIG. 1 shows an embodiment of the present invention, in which hot plates 3.3 disposed vertically facing each other are formed by providing heating means such as a heater inside, and are heated by hydraulic pressure. It is designed so that it can be pressed up and down with a device. Disk-shaped heating protrusions 4.about.4 are protruded at the end of the upper surface of the lower hot plate 3 and the end of the lower surface of the upper hot plate, respectively. The heating protrusion 4 is formed so that the area of its tip surface is about 1-2 to 4 am2. The heat insulating material 5 is made of a material having heat resistance and heat insulating properties such as asbestos and is formed into a sheet shape, and has through holes 12°, 12 . . . corresponding to the dark areas of the heating projections 4.
is perforated. This insulation material 5 is the lower hot plate 3
They are arranged on the lower surface and the upper surface of the upper hot plate 3, respectively, and stacked on the upper surface of the lower hot plate 3 and the lower surface of the upper hot plate 3 with each heating protrusion 4 passed through each through hole 12. It can be detachably attached. Therefore,
As shown in FIG. 2, the upper surface of the lower hot plate 3 and the lower surface of the upper hot plate 3 are covered with a heat insulating material 5, with the heating protrusions 4, 4, . . . The protruding dimension of each heating protrusion 4 is set to be slightly larger than the thickness of the heat insulating material 5, and the tip of the heating protrusion 4 is 0.01 to 1. It is designed to protrude beyond the surface of the heat insulating material 5 with a dimension of about 0 mm. Here, lower hot plate 3
It is sufficient to simply place the heat insulating material 5 on top of the hot plate 3, but in order to prevent the heat insulating material 5 from falling off the hot plate 3 above, suction holes 13, 13, etc. are provided in the hot plate 3. The heat insulating material 5 is attached to the lower surface of the hot plates 1 and 3 and held by the suction force from the suction holes 13, 13, . . . . When welding the laminate 2 using the spot welding device formed as described above, a plurality of inner layer laminates 2 with circuits provided on the surface are attached to the prepreg 1 as shown in the layer configuration shown in FIG. At the same time, the outer layer laminate 2 or @ foil 8 is superimposed on the outside through the prepreg 1, and this laminate 10 is set on the upper and lower hot plates 3, 3 open, and the upper and lower hot plates are stacked. This can be done by sandwiching the laminate 10 between 3.3 and pressing. When tightened in this way, the hot plates 3, 3
In this case, only the heating protrusions 4, 4, . heating and pressure will not work. Therefore, the prepreg 1 of the laminate 10 is melted and hardened only at the heating protrusions 4, 4, . . . , and each laminate 2 can be welded spot-wise through the prepreg 1. Since the heat insulating material 5 prevents heat from acting on the prepreg 1 in areas other than the one spot where it is spot-welded, it is possible to reduce the effect on the thermal history of the prepreg 1. In this way, as shown in FIG. 8, the ends of the laminate 10 are spot-welded 11 to integrate the laminate 10.
It is used for multilayer lamination molding as shown in the figure. FIG. 3 shows another embodiment of the present invention, in which the lower surface of the upper hot plate 3 is not provided with heating protrusions 4 and is formed as a flat surface. Spot welding can also be performed with this embodiment. In the embodiment shown in FIG.
A large number of through holes 15, 15...
The metal heating pins 16, 16, . At the position of the heating protrusions 4, 4...
It is designed so that it can be set up. In this device, the position of the heating protrusion 4 can be changed according to the size of the laminate 2, etc., and various laminates 2 can be spot-welded using one type of hot plate 3. In FIG. 4(a), the through holes 15, 15... are shown only in the periphery of the heat insulating material 5, but in reality, there are a large number of through holes 15, 15, etc. arranged in a grid pattern on the entire surface of the insulating material 5. Through holes 15, 15, . . . are formed. Further, as shown in FIG. 4(b), a fitting recess 17 is provided in the hot plate 3 corresponding to each through hole 15, and the base of the heating pin 16 is fitted into the fitting recess 17, so that the heating pin 16 can be attached. It may be made stronger. The hot plate 3 shown in FIG. 4 may be used in both upper and lower elbows as in the case of FIG. 2, or may be used in either the upper or lower direction as in the case of FIG. In addition to the circular shape, the spot weld 11 can also be formed into a C-shape as shown in FIG.
The gas generated in the surrounded area can be extracted from the C-shaped gap.

。As described above, in the present invention, a plurality of heating protrusions are provided protruding from at least one of the upper surface of the lower hot plate and the lower surface of the upper hot plate at the location where spot welding is to be performed, and the location of the heating protrusion is The surface on which the heating protrusions protrude is covered with a heat insulating material, so by sandwiching the laminate and prepreg laminate between the upper and lower hot plates and applying pressure, multiple heating protrusions can be used to The laminates can be spot-welded at the same time at different locations, making the spot welding work more efficient.Also, the parts other than the heating projections are covered with heat insulating material, making it possible to weld the welded parts in a spot-like manner. It is possible to prevent heat from acting on the prepreg in other parts, and to reduce the influence on the thermal history of the prepreg.
