外観不良の発生を防止するものとされている。DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a hot plate apparatus according to the present invention. The hot plate apparatus 1 is basically composed of a lens receiving jig 2, a housing receiving jig 3 and a hot plate 4.
Contact part 21 provided on lens 21 and housing 22
The point of melting and welding a and 22a is similar to that of the conventional example, but according to the present invention, the heating plate 4 is provided with a fluororesin coating sheet 5 (hereinafter abbreviated as sheet 5).
Is attached to prevent the occurrence of the appearance defect described in the conventional example.

れて市販が行われているものである。The structure of the hot plate 4 and the sheet 5 will be described in more detail below. First, the sheet 5 is coated with a fluororesin on the surface of a sheet-shaped member having excellent mechanical properties such as heat resistance and tensile strength. For example, it is a commercially available product that is called a heat tape as a surface protection material for a heater.

されている。In this embodiment, the surface of the hot plate 4 that contacts the housing 22 is covered with the sheet 5 at an appropriate interval D, and at this time, the hot plate 4 of the housing 22 melts it. The area of the sheet 5 is set so that the portion in which the contact is performed, that is, the entire contact portion 22a is covered.

り、これにより溶融工程が行われる。The sheet 5 is stretched from four sides by coil springs 6 as shown in FIG. 2, so that the hot plate 4 is fixed to the housing receiving jig 3, that is, the housing 2.
When approaching the contact portion 22a of the second coil 2, the coil spring 6 expands, and the sheet 5 has a gap D.
The heat plate 4 and the contact portion 22a are finally sandwiched between the heat plate 4 and the contact portion 22a (see FIG. 3), so that the heat generated by the heat plate 4 is transmitted to the contact portion 22a. Thus, the melting step is performed.

のとなる。Next, when the hot plate 4 and the housing receiving jig 3 are separated when the contact portion 22a is melted,
Due to the tension of the coil spring 6, first, the heating plate 4 and the seat 5 are separated from each other, and when the distance is further increased, the distance between the seat 5 and the contact portion 22a is also separated (see FIG. 4). Therefore, in this state, the heat plate 4 is retracted from between the lens receiving jig 2 and the housing receiving jig 3 and the receiving jig 2 and the housing receiving jig 3 are pressed against each other in the same manner as described in the conventional example. As a result, the lens 21 and the housing 22 are joined together.

First, a portion of the heating plate 4 which is in contact with the housing 22 is stretched by the coil spring 6 so as to have a gap D. Since it is covered with 5, the adhesion of the resin member to the hot plate 4 side due to melting occurs on the sheet 5.

のとなる。At this time, when the contact with the housing 22 is not made, a gap D is generated between the heat plate 4 and the sheet 5, so that the waiting time before the next melting operation is performed. Does not heat the adhered resin member, so that carbonization due to overheating does not occur.

はない。Further, since the sheet 5 is made of a fluororesin coating which is incompatible with most resin members, the resin member having the housing 22 that causes carbonization, such as ABS resin, is melted. The above-mentioned actions and effects are further ensured by the fact that the above-mentioned substances do not substantially adhere. Although the sheet 5 has been described as being coated with a fluororesin in this embodiment, the sheet may be a sheet made of fluororesin, and it may be one in which the molten material of the resin member does not easily adhere and is excellent in heat resistance. As long as it is a sheet of other material or a sheet coated with other material, it does not impair the gist of the present invention.

When a resin member having a higher melting temperature is used on the side of, the sheet 5 may be provided on the side of the lens 21, or may be provided on both sides.

するものである。As described above, according to the present invention, the fluororesin coating sheet is provided at least on the side of the surface of the hot plate that is in contact with the resin member that is likely to be carbonized, with a proper gap with the surface. By using a hot plate device for welding resin members that is stretched by springs, firstly, even if adhesion occurs, the resin member touches the hot plate at a time other than when the melting process is performed. Secondly, by preventing the carbonization from occurring, and secondly, by making the sheet coated with the fluororesin, it is assumed that the adhesion causing the carbonization is not substantially caused, and thus the carbonization is performed. It is possible to prevent the resin member from being transferred from the hot plate to the vehicular lamp again to cause a defective appearance and to improve the yield. Therefore, the productivity of this type of vehicular lamp is improved and the appearance is extremely excellent. It is effective.
