Abstract
The utility model discloses a wave-soldering jig suitable for a wire harness component. The wave-soldering jig comprises at least one accommodating groove which is used for accommodating a PCB and is formed a jig body, and a frame portion which is corresponding to the accommodating groove. The wave-soldering jig is characterized in that the frame portion is symmetrically and fixedly provided with upright columns located at two side edges of the accommodating groove; a fixed cross beam made of magnetic materials crosses over space above the accommodating groove and is fixed on the upright columns; the polarity of a movable cross beam is opposite to the polarity of the fixed cross beam; and the movable cross beam and the fixed cross beam are matched with each other so as to be used for clamping an insulation sleeve part of the wire harness component. With the wave-soldering jig of the utility model adopted, the atomization of wave soldering of wire harnesses can be realized, and welding efficiency can be increased, and welding quality can be stabilized, and technological progress can be embodied.
Description
Technical field
The utility model relates to the SMT production technology of PCB, relates generally to specifically in this production technology for clamping the Structure Improvement Design of the tool of PCB.
Background technology
PCB(Printed Circuit Board printed circuit board (PCB)) SMT(Surface Mounted Technology surface mounting technology) in production technology, relate to Wave crest Welding technology, this is ripe in PCB processing procedure and common solder technology, it mainly comprises scaling powder sprinkling system, pre-heating system, track transfer system, tin cream tank systems.Its processing step is: first, direct insertion element is plugged in the relevant position above PCB, and the pin of element exposes from the reserved through hole of PCB, is exposed to PCB bottom surface; Then, adjust parameter of wave-soldering, comprise scaling powder sprinkling amount, preheat temperature, orbit parameter etc.; The 3rd step, PCB is pressed in tool holding tank and is flat on track, and product is crossed stove, when PCB arrives tin cylinder, what in tin cylinder, place is high-temp liquid tin, and its temperature is 250 ℃-260 ℃, PCB bottom surface contacts with high-temp liquid tin, and Molten Tin is bonded on component pin, and element is soldered; Finally, temperature reduces, and Molten Tin solidifies, and PCB comes out of the stove, and welding completes.
Known, components and parts comprise pin and package casing, generally, package casing has certain rigidity intensity, like this when pin inserts PCB preformed hole, whole element is in erectility, but when needs weld wire harness shaped element part, because it has certain length and shell is soft materials, such as plastic pipe sleeve etc., it is upper that wire harness units can not stand upright on PCB, cannot cross stove welding.The Wave soldering fixture of prior art, for example the patent documentation of publication number CN202861582U discloses a kind of furnace tool of crossing, and it comprises tool body, for placing the sunk type cavity (holding tank) of PCB, and for clamping four knob fixtures of PCB.The patent documentation of publication number CN2029980694U has disclosed the another kind of furnace tool of crossing, and enterprise comprises tool body and the groove that holds PCB, but these tools all cannot be realized the welding of wire harness shaped element part.So the welding of wire harness shaped element part adopts manual welding mode substantially, both not high the and welding quality of efficiency was difficult to guarantee.
So those skilled in the art are necessary further to improve the furnace tool of crossing of prior art, to facilitate the stove of crossing of wire harness shaped element part to weld.
Summary of the invention
For the defect of above-mentioned prior art and the technical problem of existence, the technical problems to be solved in the utility model has been to provide a kind of Wave soldering fixture that is applicable to wire harness components and parts.
The utility model solves the problems of the technologies described above adopted technical scheme: be applicable to the Wave soldering fixture of wire harness components and parts, comprise be opened on tool body at least one for holding the holding tank of PCB and with respect to the frame portion of holding tank; It is characterized in that, in the frame portion of described holding tank dual-side, be symmetrically fixed with column; The fixedly Heng Liang being made by magnetic material is across holding tank superjacent air space and be fixed on aforementioned column; Moved cross beam is contrary with fixed cross beam polarity, and coordinates with fixed cross beam, for clamping the insulating sleeve part of wire harness components and parts.
Preferred technical scheme: described fixedly Heng Liang and moved cross beam are all selected high temperature resistant magnet.
Preferred technical scheme: described column is fixed on the dual-side of holding tank length direction.
Preferred technical scheme: described tool body adopts synthesis stone material.
Technique effect of the present utility model: the design increases column on tool, utilize the magnetic force of two crossbeams to add the insulating sleeve of holding wire harness, thereby wire harness is stood upright on PCB, realized the automation of wire harness wave soldering, improved welding efficiency, stablize welding quality, embodied outstanding technological progress.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, further illustrate advantage of the present utility model and with respect to the outstanding contributions of prior art, understandable, following embodiment is only the detailed description to the better embodiment of the utility model, should not be construed as any restriction to technical solutions of the utility model.
As shown in Figure 1, 2, tool body 1 adopts synthetic stone or metal to make, and has the holding tank 11 suitable with PCB shape, thickness in the middle of it, and the remainder of body forms frame portion 12.In frame portion 12, be screwed a column 13.As shown in Figure 3, in the middle of fixed cross beam 14, nested high temperature resistant magnet is fixed on column 13 across the superjacent air space at holding tank 11 length directions screw.Moved cross beam 15 is consistent with fixed cross beam 14 length, but middle nested magnet polarity is contrary with fixed cross beam 14.According to the needs of PCB, this magnetic fixture can be set up many covers on tool, and to meet the needs of wire harness plug-in position, the present embodiment has been set up two parallel fixed cross beams 14.
During work, first wire harness pin is inserted in PCB preformed hole, and PCB is placed in holding tank 11, and turn knob fixture is fixed PCB, the insulative of wire harness is partly placed between fixed cross beam 13 and moved cross beam 14, thereby two crossbeams clamp wire harness because magnetic force reason is close together, make soft wire harness can as other components and parts, stand upright on PCB upper, then enter welding in stove, after PCB comes out of the stove, separately moved cross beam 15, removes knob fixture, takes out PCB.
The utility model, by increasing column on tool, utilizes the magnetic force of two crossbeams to clamp the insulating sleeve of wire harness, thereby wire harness is stood upright on PCB, realize the automation of wire harness wave soldering, improve welding efficiency, stablized welding quality, embodied outstanding technological progress.
Below preferred embodiment of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
