Description

Technical Field

[0001] The utility model relates to the technical field of wave soldering machines, in particular to an energy-saving wave soldering machine. Background Art

[0002] Wave soldering machine is to make molten solder (lead-tin alloy) spray into solder wave crest as required by design through electric pump or electromagnetic pump, or by injecting nitrogen into solder pool, so that printed circuit board with components pre-installed can pass through solder wave crest, and realize mechanical and electrical connection between component soldering end or pin and printed circuit board pad. When using wave soldering machine to solder computer motherboard or other plates, it can effectively ensure the soldering effect. At present, there are still some shortcomings in the existing wave soldering machine for computer motherboard processing. First of all, the existing computer motherboard processing The wave soldering machine is not convenient to move. When the wave soldering machine needs to be moved due to work needs or changes in the processing flow, it needs multiple people to carry it, and the operation is cumbersome, which reduces the convenience of using the wave soldering machine for computer motherboard processing. Secondly, during the operation of the existing wave soldering machine for computer motherboard processing, the welding fume generated is mostly directly discharged. Since the welding fume contains solder particles, it is easy to be absorbed by the operator when it is directly discharged, thereby damaging the operator's health, thereby reducing the safety of using the wave soldering machine for computer motherboard processing.

[0003] Prior art publication number: CN212191612U, provides a technical solution: a wave soldering machine for computer motherboard processing, including a wave soldering machine body and an exhaust port, a base is fixedly installed at the bottom of the wave soldering machine body, and a roller is fixedly installed at the bottom of the base, and a support seat is horizontally penetrated at the vertical end of the base. In the utility model, when the wave soldering machine body is operating normally, the support seat cooperates with the spring to support the wave soldering machine as a whole, and the spring can also perform shock-absorbing support for the wave soldering machine body through its own elastic potential energy. When the device needs to move, the hydraulic cylinder is controlled to work, the hydraulic cylinder pushes the support seat upward, the spring is deformed, and the roller at the bottom of the base abuts the ground. At this time, the overall movement of the wave soldering machine can be achieved through the roller, and after moving to the specified position, the hydraulic cylinder pulls back the support seat to reset it, thereby ensuring the overall stability of the wave soldering machine while improving its convenience of movement.

[0004] but:

[0005] The wave soldering machine will produce smoke when working, and the welding smoke will contain solder particles, which need to be filtered before discharge. However, during the filtering process, after the filter device has been used for a long time, a large number of small tin particles will remain on the filter net, causing the filter holes to be blocked, the exhaust fan's air suction becomes smaller, and the welding smoke will overflow through the gap between the welding machine and the welding door.
