Problems solved by technology

[0003] Brazing is often required in the capacitor industry, and there will be an oxide film between the brazing materials. The most traditional method to remove the oxide film during brazing is that workers use tools to rub the brazing place continuously until the oxide film is completely worn. This method of removing the oxide film is not only difficult to grasp the accuracy, but also inefficient; some existing brazing machines are connected with a rotating mechanism above the soldering iron tip, and the soldering iron tip is attached to the welding surface before welding. , Grind off the oxide film on the welding surface, and then weld. Although this method does not require manual removal to grasp the accuracy, the efficiency is still low

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see figure 1 , a kind of ultrasonic brazing device, comprises brazing machine 1, and described brazing machine 1 is provided with ultrasonic transducer 2, and described ultrasonic transducer 2 is connected with ultrasonic generator 3, and described ultrasonic transducer 2 It is arranged on the soldering iron head 11 of the soldering machine 1 . This arrangement enables the ultrasonic transducer 2 to be brazed directly after the oxide film on the welding surface is removed without further movement. The speed of removing the oxide film by ultrasonic wave before brazing is very fast. By adjusting the frequency of the ultrasonic wave, only the oxide film will be removed and the unoxidized part will not be removed, and the removal accuracy is high.

[0012] see figure 2 , Embodiment 2, the difference from Embodiment 1 is that the brazing machin...

Abstract

The invention discloses an ultrasonic soldering device, which comprises a soldering machine. An ultrasonic transducer is arranged on the soldering machine. The ultrasonic transducer is connected with an ultrasonic generator. Oxide films can be removed very quickly before soldering by using ultrasonic waves, only the oxide films instead of parts which are not oxidized are removed by adjusting the frequency of the ultrasonic waves, and the removing accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of welding, in particular to an ultrasonic brazing device. Background technique [0002] Brazing is to use a metal material with a lower melting point than the base metal as the solder, heat the weldment and the solder to a temperature higher than the melting point of the solder and lower than the melting temperature of the base metal, use liquid solder to wet the base metal, fill the gap between the joints and The method of interdiffusion with the base metal to realize the connection of the weldment. The brazing deformation is small, and the joint is smooth and beautiful. It is suitable for welding precision, complex and components composed of different materials, such as honeycomb structure plates, turbine blades, hard alloy tools and printed circuit boards. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and oxide films to ensure the assembly clearance ...
