Background technology
At present, circuit developer is when using electric iron to carry out the welding of components and parts pin, the usual employing right hand takes electric iron, left hand to take solder stick, electric iron melts welding wire and welds, this manual pcb welding method is because the normalization of operation is wayward, different operators makes the quality of welding very different, and the problems such as short circuit, short circuit, rosin joint often occur, the qualification rate of product not high and welding after connect shape unsightly.
Summary of the invention
The object of the present invention is to provide a kind of pcb welder, the uppity technical problem of working specification in pcb welding process in solution prior art.
In order to solve this technical problem, the present invention adopts following technical scheme:
A kind of pcb welder, comprise hollow pipe, one end and the drawing mechanism of described hollow pipe are tightly connected, and the other end and connecting portion seal and connect, and described drawing mechanism is funnel-form, and the tapering of drawing mechanism is detachable is provided with end cap; Be provided with piston in described hollow pipe, piston runs through along its axis direction copper pipe, is tightly connected between copper pipe and piston, and copper pipe through connecting portion, and can slide along movable part, and copper pipe differs from the one end being connected with piston and is provided with handle; Be provided with spring in hollow pipe, spring is between piston and drawing mechanism; The outer sheathed shell of described hollow pipe, the two ends of shell are connected with drawing mechanism and connecting portion respectively; Heat insulating mattress is provided with between shell and hollow pipe; Be provided with resistance wire between hollow pipe and hollow pipe, between hollow pipe and resistance wire, be provided with thermally conductive insulating layer.
This device is adopted to carry out the process of pcb welding as follows:
1), end cap get lodged on the discharging opening in drawing mechanism tapering, take off handle, required solder stick or soldering paste are put into hollow pipe by copper pipe, then handle is installed to copper pipe and differs from the one end being connected with piston.
2), by resistance wire be connected with external power, resistance wire generates heat, and transfers heat to conduction to hollow pipe, and the solder stick in hollow pipe is dissolved.
3), after solder stick dissolves, the discharging opening of end cap from drawing mechanism tapering is taken off, is that the solder stick melted flows out from discharging opening, is added dropwise to the welding position of components and parts to be welded.Because discharging opening aperture is less, liquid scolding tin can not flow out naturally owing to being subject to surface tension, now need operator to hold shell and press handle simultaneously, then copper pipe is equivalent to piston rod driven plunger and moves in hollow pipe, piston compression spring makes the pressure in hollow pipe increase, ensure that liquid scolding tin flows out, weld smoothly.The amount flowing out liquid scolding tin depends on the size acting on pressure on handle, if pad is little, needs many scolding tin few, so applies external force just less, otherwise want large.
4), at the end of welding, unclamp the hand of pressing handle, piston moves upward under the restoring force of spring, and the unnecessary scolding tin drop being suspended on discharging opening can be sucked in hollow pipe again, prevents from falling on pcb and causes short circuit.
Further improvement, the tapering of described drawing mechanism is provided with adjusting device, according to the size of pad, is adjusted the size of materials device discharging opening by adjusting device, controls the flow of liquid solder.
Further improvement, the one end near handle on described connecting portion is connected with sleeve, and jacket casing is located at the outside of copper pipe, and the length of sleeve is less than the spacing of handle and connecting portion, when welding, hold sleeve thumb press handle simultaneously, a hand is only needed to operate, easy to operate.
Further improvement, described sleeve lining is provided with internal thread, and connecting portion is provided with external screw thread, and sleeve is threaded with connecting portion, is threaded for convenience detach.
Further improvement, is provided with boss in the middle part of the inwall of described hollow pipe, and spring is arranged between piston and boss, shortens the length of spring, reduces cost.
Further improvement, described hollow pipe seals to connect to be with drawing mechanism, connecting portion and is threaded, and is threaded for convenience detach.
Compared with prior art, the present invention has following beneficial effect:
1, pcb welder of the present invention, by arranging copper pipe, resistance wire, conveniently solder stick, tin cream being put into hollow pipe heating and melting, and controlling the outflow of liquid solder by the motion of piston, make working specification in pcb welding process easy to control, ensure welding quality.
2, by arranging boss in the middle part of the inwall of hollow pipe, spring is arranged between piston and boss, shortens the length of spring, reduces cost.
3, adjusting device is set by the tapering at drawing mechanism, then according to the size of pad, the size of materials device discharging opening can be adjusted by adjusting device, control the flow of liquid solder.
