Abstract

(57) [Abstract] [Purpose] To enable constant quality soldering without requiring skill [Structure] A pipe 4 is attached to the grip 1 and the pipe 4 is attached.
The cream solder is transferred from the cream solder transfer device 3 to the work, the pipe 7 is also attached to the grip portion 1, and hot air is blown from the hot air generator 6 to the cream solder application part of the work through the pipe 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a solder welding apparatus capable of applying cream solder to a work and then blowing hot air on the work to carry out solder welding without contact with a trowel.

[0002]

[Prior art]

 For soldering, it is necessary that the amount of solder, heating time, pressure and direction to the iron tip, etc. be appropriate depending on the nature of the work. Therefore, a worker needs a long experience and can to make proper soldering, but since the soldering is performed by experience, the quality variation is inevitable. Therefore, an object of the present invention is to provide a solder welding apparatus capable of performing soldering of a constant quality without requiring skill.

[0003]

[Means for Solving the Problems]

 In order to achieve the above object, the solder welding apparatus of the present invention is equipped with a pipe that automatically pushes out an appropriate amount of cream solder according to the work. It also has a pipe that automatically sends out appropriate hot air.

[Action]

 According to the work, the solder is applied to the work through the pipe based on the preset extrusion amount. Hot air is blown onto the applied cream solder through the pipe based on a preset time.

【Example】

 The implementation will be described with reference to the drawings. The grip portion 1 is a portion that is gripped by an operator to perform soldering work. Further, a pipe 4 is mounted inside the grip portion 1, and a cream solder transfer device 3 is provided at the base of the grip portion 1, and a part thereof is provided. , Terminals A and B are provided side by side. As shown in the circuit diagram, the relay sequence 9 has a relay R1, a time T1 which can be set in advance, and terminals A'and B ', which are provided side by side. The handle 1 is provided with a switch PB1. When the operator turns on the switch PB1, the relay sequence 9 of the cream solder transfer device 3 is magnetically excited through the terminals A'B 'of the circuit to activate the cream solder transfer device and transfer the paste 4 to the work to apply the cream solder. . A pipe 7 is mounted inside the handle portion 1 and a hot air generator 6 is provided at the base portion thereof, and terminals B and C are provided side by side with the hot air generator 6. As shown in the circuit diagram, the relay sequence 10 has a relay R2, a time T2 whose time can be set in advance, and terminals C and D are provided side by side. The handle portion 1 is provided with a switch PB2. When the operator turns on the switch PB2, the relay sequence 10 of the hot air generating device 6 is magnetically excited through the terminals C ′ and D ′ of the circuit, the hot air generating device 6 operates, and the hot air is applied with solder through the pipe 7. It is sprayed onto the work piece and can be easily soldered in a non-contact state.

[0005]

[Effect of device]

 As described above, by using the solder welding apparatus of the present invention, it is possible to easily carry out soldering of a certain quality.
