Description
Technical field
The utility model belongs to the tin material supply technical field of crest welder, is specifically related to a kind of technological improvement that adds the tin device automatically of crest welder.
Background technology
Wave soldering (wave-soldering) is mainly used in conventional via plug-in mounting printed circuit board electrical fitting technology, and surface-assembled and through-hole mounting components and parts load in mixture technology.The surface-assembled components and parts that are applicable to wave-soldering technology have rectangle and cylindrical slice component, SOT and less devices such as SOP.At present domestic crest welder commonly used mainly contains that these are several: desk-top crest welder, dual waves welding machine, little crest welder and unleaded crest welder.
The wave-soldering welding procedure comprises: finish point (or printing) glue, mount, the printed board of adhesive curing, plug-in mounting through-hole component moves forward with conveyer belt from the arrival end of crest welder, during by solder flux foaming (or spraying) groove, the pad of printed board lower surface, all components and parts terminations and pin surface are applied the very thin solder flux of last layer equably.Along with conveyer belt operation, printed board enters the preheating zone, and the solvent in the solder flux is volatilized to be fallen, and rosin and activating agent begin to decompose and activate in the solder flux, and oxide-film and other pollutant on printed board pad, components and parts termination and pin surface are eliminated; Simultaneously, printed board and components and parts obtain abundant preheating.
Printed board continues operation forward, and the solder wave of first fusion is at first passed through in the bottom surface of printed board.First solder wave is random ripple (vibration wave or a turbulent ripple), and all pad, the components and parts in bottom surface of scolder being got to printed board weld on end and the pin; The scolder of fusion soaks on the metal surface that purifies through solder flux and spreads.Afterwards, the solder wave of second fusion of underrun of printed board, second solder wave is level and smooth ripple, level and smooth ripple separates the crossover between pin and the weldering end, and removes and draw point weld defects such as (icicles).When printed board continues after second solder wave left in operation forward, cooling cooling formation solder joint is promptly finished welding naturally.
Common solder wave produces like this: melt solder produces bore at rabbling mechanism in molten tin bath, and the bore arranged outside has grade ripple spare to allow molten tin flow through, and produces the tin face that gushes a little more than molten tin liquor position height; When circuit board when gushing the tin face, the element of circuit board is eaten tin.Yet along with the carrying out of welding job, molten tin liquor position is whole can to descend, and causes circuit board wicking height to be affected, and then influences welding quality.And settling mode of the prior art is: when tin cylinder tin after a little while, liquid level sensor will be reported to the police, and adopts methods such as manually adding tin then.Yet artificial the interpolation greatly reduces the efficient of production, and is unfavorable for controlling the balance of whole tin liquor position, can cause the sequelae of whole welding process, and be too much etc. as tin ripple shakiness, scruff.The present invention comes therefrom.
