The utility model discloses constitute by crest power supply, transfer passage, crest nozzle assembly, back flow, electric heater and solder groove.
Description
Technical field
The utility model relates to a kind of peak generator of convertible crest width, specially refers in the printed circuit board (pcb) automatic welding device, produces the peak generator of the convertible crest width of liquid metal soft solder material crest.
Background technology
Since printed circuit board wave-soldering connection had been invented by Britain Fry ' s Metal company in 1956, the wave soldering technology had been widely used in the domestic and international electronic product manufacturing enterprise.Yet recent decades, what both at home and abroad crest welder manufacturing enterprise provided to market is the crest welder of set wave peak width entirely.
Use the crest welder of set wave peak width, when welding PCB width is suitable with the crest width, do not have problems,, will cause certain waste when PCB width during much smaller than the crest width.In actual production, the width that PCB often occurs is less than half of crest width.Weld the PCB of same width, the crest width is wide more, and the area that fusion welding exposes in air is just big more, and the scolder oxidation is just many more, and energy consumption and pollution are also big more simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of peak generator of convertible crest width, and the scolder oxidation that its width that has solved PCB in the background technology is produced during much smaller than the crest width is many, energy consumption and heavy-polluted technical problem.
Technical solution of the present utility model is: a kind of peak generator of convertible crest width, comprise crest power source, crest nozzle assembly and the transfer passage 4 that connects crest power source and crest nozzle assembly, its special character is: described crest nozzle assembly comprises a series of crest nozzles 6 that the crest exit width is different.
Connect or the quick-speed jigs crimping for bolt between above-mentioned crest nozzle assembly and the transfer passage 4.
Above-mentioned crest nozzle assembly is single crest nozzle assembly or dual waves nozzle assembly; Described single crest nozzle assembly comprises a crest power source and a crest nozzle assembly that is connected with described crest power source; Described dual waves nozzle assembly comprises two crest power sources and two crest nozzle assemblies that are connected with described two crest power sources respectively.
Above-mentioned crest nozzle assembly comprises the current stabilization orifice plate 5 that is arranged in the crest nozzle 6.
Above-mentioned crest power source is the mechanical pump of phase asynchronous induction electromagnetic pump, single-phase induction formula electromagnetic pump or motor-driven impeller.
Above-mentioned phase asynchronous induction electromagnetic pump comprises three-phase electromagnetic system 1 and electromagnetic force active region 2.
Be connected with welding between above-mentioned transfer passage 4 and the crest power source.

Embodiment
Accompanying drawing is embodiment, adopts the utility model in the phase asynchronous induction electromagnetic pump crest welder of single/double wave crest series of products.
The utility model is achieved by the following technical solution: the peak generator of the convertible crest width of design is made up of crest power source, transfer passage 4, crest nozzle assembly, return duct 3, electric heater 7 and solder bath 8.Its medium wave peak power source, transfer passage 4 and crest nozzle assembly constitute solder crest dynamical system jointly.The crest power source can be phase asynchronous induction electromagnetic pump, can be single-phase induction formula electromagnetic pump, also can be the mechanical pump of motor-driven impeller.Phase asynchronous induction electromagnetic pump is made up of three-phase electromagnetic system 1 and electromagnetic force active region 2.Transfer passage 4 usefulness stainless steels or titanium alloy plate are made, and are connected with welding between the crest power source, and are connected with bolt between the crest nozzle assembly or use the quick-speed jigs crimping, easily dismantle or replacing.The crest nozzle assembly is made of stainless steel or titanium alloy plate, is made up of a series of crest nozzles 6 that the crest exit width is different, and current stabilization orifice plate 5 is equipped with in crest nozzle 6 inside.The crest nozzle assembly is divided into single crest nozzle assembly and dual waves nozzle assembly, is respectively applied for single crest welder and dual waves welding machine.Electric heater 7 can be the electrothermal tube that is immersed in the scolder cell body, also can be the electric hot plate that is attached to the solder bath outer wall.Solder bath 8 usefulness stainless steels or titanium alloy plate are made, and by changing the crest nozzle 6 of different crest exit widths, reach the purpose of conversion crest width.Thereby reduce the scolder oxidation, energy efficient reduces and pollutes.
