Description
The present invention relates to a thermoplastic resin structure bonded body and a bonding method therefor, and to a thermoplastic resin structure bonded body made of a plurality bonded to one and a bonding method for the same.
In general, thermoplastic structures such as plastic pipes or plastic molds are joined by bonding or melting of the joint surface through direct heating of the joint surface. However, since the precision and durability of thermoplastic resin structures used in precision applications such as parts of a vehicle are deteriorated by the aforementioned method, the joint surfaces facing each other with the thermoplastic resin structures are fused by ultrasonic waves, It joins as it generates heat while rubbing by this fine vibration. In more detail, any one of the structures and the other one of the structures are bonded to each other while the contact surface is melted by ultrasonic welding while the bonding surface is in close contact, or the contact surface is rubbed at high speed and the contact surface is rubbed. As they are melted by exotherm, they are joined together.
However, such a thermoplastic resin structure can be joined by ultrasonic welding or friction welding only when the contact surface is always in a straight line. If any one of the contact surfaces is curved, the part is excited by bending, so the excited part is not fused by ultrasonic welding, or the excited part is not fused because it is not rubbed.
On the other hand, induction heaters have recently emerged. The induction heater refers to an electromagnetic induction heating device. The operating principle is that when an electric current is sent to the coil of the main body, an induced electromagnetic force is generated in the coil, and when the magnetic force line of the induced electromagnetic force passes through the metal, the resistance component contained in the metal material An eddy current is generated by (iron component). In addition, the eddy current generates only the metal itself, thereby generating induction heating, in which only the metal becomes hot.
For example, the home induction heater (also called induction range) is only the pot is heated when the coil provided on the top plate of the main body to provide a magnetic line to the pot. When the induction heater is heated, the heating stops immediately when the pot is lifted, so it is not only hot and safe to touch the top plate, but also energy is generated because energy is generated only at the part where the coil and the pot are in contact.

It includes a metal plate for melting the opposing surface of the first structure and the second structure while joining the first structure and the second structure while generating heat at a high temperature.
The metal plate may have at least one communication hole for communicating the melt, or at least one groove for receiving the melt.
In contrast, the bonding method according to the present invention, the first structure input step of injecting a first structure made of a thermoplastic resin into the induction heater; A metal plate stacking step of stacking a metal plate on an upper side of the first structure; A second structure stacking step of stacking a second structure made of a thermoplastic resin on an upper side of the metal plate; An opposite surface melting step of melting the opposite surfaces of the first structure and the second structure by heating the metal plate with the induction heater; And a cooling step of cooling the first structure and the second structure.
In addition, the bonding method according to the present invention, the sequential layer step of sequentially laminating a second structure made of a metal plate and a thermoplastic resin on top of the first structure made of a thermoplastic resin; An input step of injecting the stacked first structure, the metal plate, and the second structure into the induction heater; An opposite surface melting step of melting the opposite surfaces of the first structure and the second structure by heating the metal plate with the induction heater; And a cooling step of cooling the first structure and the second structure.
The cooling step may include, for example, a first slow cooling step of slowly cooling the first structure and the second structure in which the opposite surface is melted inside the induction heater; And a second slow cooling step of discharging the first structure and the second structure to the outside of the induction heater to perform secondary cooling at room temperature.
Here, the aforementioned bonding method may further include a preheating step of preheating at least one of the first structure, the second structure, and the metal plate before the metal plate is heated.
The preheating step may be performed, for example, before the first structure, the metal plate, and the second structure are introduced into the induction heater, or may be performed after being introduced into the induction heater.
The thermoplastic resin structure joined body and the bonding method therefor according to the present invention, the first structure and the second structure as the metal plate is heated while melting the opposite surface of the first structure and the second structure by the induced electromagnetic force of the induction heater. The structure can be easily joined, and even when the first and second structures are bent on the opposite surfaces of the first plate and the second structure, when the bend is formed on the metal plate, the structure can be bonded to the plurality of thermoplastic structures regardless of the shape. have.
In particular, since the opposing surfaces of the first structure and the second structure are melted by the heat generation of the metal plate, the first structure and the second structure are bonded to each other, so that precise bonding is possible and excellent durability can be expected. It can be used in applications requiring precision.
In addition, when the melt flows into the communication hole of the metal plate or is accommodated in the unevenness of the metal plate, the first structure and the second structure can be very firmly bonded.
In addition, since the cooling is performed sequentially in the induction heater and the outside after the melt is formed, it is possible to more firmly join the joint portion of the first structure and the second structure.
In addition, when the metal plate is heated after preheating at least one of the first structure, the second structure, and the metal plate, not only the joint portion of the first structure and the second structure can be more firmly bonded, but also the melting time of the opposite surface. It can be shortened.
