る。 Conventionally, the method of thermally bonding thermoplastic resin components involves forming melting grooves in the component in advance, bending the grooves, and thermally bonding the components, and also attaching the thermal bonding points of both components to be thermally bonded. The method used was to heat them, then butt them together and thermally bond them together. However, the former method of forming melting grooves requires a considerable amount of melting of the thermoplastic resin member;
In addition to causing heat thinning, it is also troublesome in terms of equipment as it requires a means for forming melting grooves and a bending means, and on the other hand, the latter method of butting each other after melting by heating individually also causes heat thinning due to a considerable amount of melting. As the size increases, the heating loss due to the elapse of time from heating and melting to thermal bonding also increases, and the effective use of thermal energy has not yet been achieved. Also,
There was also a method in which a thermoplastic resin member was pressed onto a hot blade, and the hot blades were pulled out from between the thermoplastic resin members while keeping them parallel, and the thermoplastic resin members were simultaneously pressed and thermally bonded to each other at the same time as they were pulled out. 41−

-25116 Publication, etc.), the hot blade is simply inserted parallel between the parts, and it is difficult to smoothly insert the hot blade between the parts because it cannot deal with variations in the thickness of the parts, etc. The degree of pressure on the surface against the hot blade is uneven, which may result in uneven fusion of parts due to the hot blade, resulting in the fusion surface not being level or the bonding strength being insufficient. It was hot. Therefore, in the method of the present invention, the drawbacks and inconveniences of the above-mentioned prior art are overcome, and extremely excellent thermal bonding can be performed. One of them is fixed in position and only the other can be moved, and one end is located on the same plane as the upper end of the member on the fixed position side,
A thermal blade whose other end is rotatable using the one end as a fulcrum is resiliently held in an inclined state where the other end is higher than the upper end of the member on the fixed position side, and comes into contact with both of the members. Then, while pressing and transferring the above-mentioned member on the transfer side to the hot blade, the hot blade is rotated around one end so as to be parallel to the thermal bonding surface of the above-mentioned members, and the above-mentioned member This is characterized in that while pressing the hot blade to the hot blade, the hot blade is pulled out from between the members in the above-mentioned parallel state, and immediately the above-mentioned members are pressed together and thermally bonded.

である。 As described above, according to the present invention, the thermoplastic resin members are interposed between the thermoplastic resin members and the thermoplastic resin members are pressed together when the hot blade is pulled out while the thermoplastic resin members are being pressed together. In order to thermally bond the
There is no cooling timing between the heat treatment of the thermoplastic resin member and the pressure bonding of the members, making it easy to thermally bond the members, making effective use of thermal energy, and almost eliminating heating loss. In addition, by achieving effective and appropriate thermal bonding in this way, the amount of heating and melting of the thermoplastic resin components is reduced, reducing heat loss of the thermoplastic resin components, and providing a good appearance in the thermally bonded state. This method exhibits various excellent effects, such as improved performance, and overcomes the drawbacks and inconveniences of conventional thermal bonding methods.

も大きいものとなる。 Furthermore, in this invention, one of the thermoplastic resin members is fixed in position and only the other is moved without moving both of the thermoplastic resin members, which is particularly suitable for thermally bonding a small member to a larger member. In addition, one end of the thermal blade is located on the same plane as the upper end of the thermoplastic resin member on the positioning side, and the other end is rotatable using this end as a fulcrum. The thermoplastic resin member is elastically held so that it is slanted above the upper end of the thermoplastic resin member on the fixed side, and is inserted between the members so as not to touch either of them, so the thermal blade can be smoothly inserted between the members. The heat blade can be inserted into the heat cutter, and even if there is a variation in the thickness of the member, it can be handled well, and the hot blade can be inserted without any problems. Then, when the thermoplastic resin member on the transition side is transferred to the hot blade by pressure, the hot blade turns around the one end and becomes parallel to the thermal bonding surface between the thermoplastic resin members. The component is evenly crimped to the hot blade, and the crimped surface of the component is evenly melted by the hot blade, eliminating uneven fusion of the component unlike the conventional method in which the hot blade is inserted horizontally between the components. This does not occur, the fused surfaces of the members are horizontal, and the bonding strength between the members is also uniform. Moreover, since the thermal blade rotates on the same axis as the forward and backward movement, it has the great advantage of being able to be equipped without requiring a mechanically complex operating mechanism.
