Description

Technical Field

[0001] The invention relates to the technical field of soldering machines, in particular to a soldering machine for processing audio circuit boards. Background Art

[0002] A soldering machine is an automated device used for soldering electronic components. It preheats the soldering area through a heating device. When the soldering area reaches the preheating temperature, the soldering machine sends the solder wire to the soldering area through a tin feeding device, so that the soldering machine heats the solder to a molten state through the welding head and makes it contact with the metal surface of the soldering area. When the solder melts, it will wet and diffuse to the metal surface of the soldering area under the action of surface tension to form a firm soldering point. The soldering area is cooled by a cooling device to achieve the welding of electronic components on the circuit board.

[0003] The audio-specific components on the audio circuit board are extremely sensitive to audio signal interference. If the welding is not firm or there is a cold solder joint, it is very likely to cause noise, distortion and other problems. Therefore, this type of component has a high requirement for welding accuracy.

[0004] In order to ensure the welding accuracy, the current soldering machine usually uses flux. The specific method is to spray the flux on the hot melt part of the solder through the nozzle to remove the oxide layer on the surface of the welding rod and reduce the surface tension of the solder. However, the above method has the following problems: First, due to the working principle and structural limitations of the nozzle, the flux may be unevenly distributed after being sprayed out, with too much flux in some places and too little or even no flux in other places, and the uniformity of flux spraying cannot be guaranteed; second, a single flux is often difficult to simultaneously achieve the two functions of removing the oxide layer and reducing the surface tension of the solder, which reduces the hot melt quality of the solder, thereby affecting the quality of welding, and is prone to problems such as loose welding or even cold welding.
