Reaction jet welding device and uses thereof

Abstract

The invention discloses an injection stream welding plant and the application thereof. The injection stream welding plant comprises a clamp, a soldering flux generator, a preheater, a solder groove with a first-level spout, a voltage-stabilizing filter and a nozzle; the preheater is arranged downstream the soldering flux generator; the solder groove is located downstream the soldering flux generator; the voltage-stabilizing filter is positioned behind the solder groove and has an overflow cover and a second-level spout, wherein, an overflow baffle with adjustable height is arranged in the middle of the overflow cover; the nozzle is arranged on above the second-level spout and provided with a millimeter-level sized spout and a pair of nozzles which extend along the parabola trace of the solder stream, are arranged symmetrically in the shape of an inverted V and combined by blast baffles and form a millimeter-level section sized solder injection stream that hangs in the air to be exposed in the upper, left and right sides. The application of the injection stream welding plant of the invention is that the application of the wave-soldering welding technology is extended to the electronic product welding field of none-plane-type welding point arrangement between electronic wires and electronic elements beyond the plane-welding PCB welding field. The injection stream welding plant has the advantages of being capable of realizing consecutive welding and being used in the welding between none-plane electronic wires and electronic elements.

Description

technical field [0001] The present invention relates to a welding device and its application, in particular to a jet flow welding device for products with non-planar solder point arrangement and its application. Background technique [0002] Tin soldering of electronic connectors in the electronics industry usually uses soldering iron soldering, wave soldering, reflow soldering, etc. For example, soldering iron is used for plug and wire, wave soldering is used for PCB pin components, and reflow soldering is used for PCB chip components. In terms of soldering efficiency and soldering quality, wave soldering and reflow soldering are at the same level, while soldering iron soldering is not as good as the former two. At present, wave soldering is only suitable for soldering PCB components, that is, tin soldering with solder joints distributed on a flat plate, and cannot be used for soldering products with non-planar solder joints. Therefore, under the current conditions, the s...
