Problems solved by technology

[0002] The existing electronic industry is becoming more and more developed, and in the wave soldering process of PCBA boards, the wave soldering furnace will produce a large amount of tin slag every day, that is, tin oxide impurities. According to statistics, a wave soldering machine produces about 4KG per day. This is because the wave soldering furnace does not have sealing measures, and the tin in the wave soldering furnace directly flows and oxidizes in the air, resulting in the generation of tin slag, and the existing tin wave grooves are all 150mm, so the tin that is too wide The wave groove also makes it easier to form oxides. On this basis, because the wave soldering furnace does not have any sealing measures, the smoke is caused to escape from the wave peak and fill the air, making the solder smoke in the production workshop pungent. , while wasting solder, it also makes the workshop environment harsh and affects the health of workers

Abstract

The invention provides an energy saving device and method for a wave soldering machine. The energy saving device comprises a device body, the wave soldering machine, a soldering machine sealing cap, a soldering wave trough, a mechanical pump and a smoke exhaust device, wherein the wave soldering machine is arranged on the device body; the soldering wave trough is arranged in the wave soldering machine; the mechanical pump is connected with the soldering wave trough and used for forming wave crests in the soldering wave trough; the soldering machine sealing cap is arranged over the wave soldering machine; the smoke exhaust device is connected with the soldering machine sealing cap in a sealed mode. By means of the energy saving device and method for the wave soldering machine, the requirements for soldering are lowered, materials are saved, and the requirement for wave soldering are met. The soldering machine sealing cap can completely prevent outside air from entering the wave soldering machine, and then smoke in the wave soldering machine is exhausted and treated through the smoke exhaust device, so that the shortcoming that smoke is exhausted out of a wave crest opening to air is overcome, and the environment of a workshop is improved while soldering tin is saved. The energy saving device and method save energy, are environmentally friendly, and do not affect the physical health of workers.
