The solder bridge prevention fixture is simple in structure, convenient to operate, and capable of effectively preventing a solder bridge phenomenon during wave soldering.
Description
Technical field
The utility model relates to a kind of wave-soldering tool, particularly relates to a kind of anti-tin tool that connects that can prevent to connect between solder joint the tin phenomenon.
Background technology
In the prior art; Tin mainly is to utilize the tin stove to carry out wave-soldering to accomplish on the real dress wiring board, scribbles weld-proof membrane on its wiring board and the copper platinum place that will go up tin exposes, through tool carrying wiring board; Make the wiring board middle part soar and level through the liquid tin crest of tin stove; Since the absorption affinity of liquid, the solder joint on the wiring board during successively through the tin stove after through the solder joint liquid tin on the last solder joint of absorption automatically, and when liquid tin is too much the company's of formation tin phenomenon; Making solder joint limit, two places is conduction path, causes real dress wiring board to produce quality problems.
The conventional method of the company's of solution tin is with flatiron the solder joint that connects tin to be carried out manual amendment; To connect metallic tin group between two solder joints of tin melts and breaks off through flatiron; Plenty of time and manpower are not only wasted in this operation; And fundamentally the company's of solution tin problem can't effectively improve production efficiency.
The utility model content
The utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of simple in structure, easy to operate, can effectively prevent the anti-tin tool that connects of the company's tin phenomenon in the wave-soldering process.
For solving the problems of the technologies described above; The utility model provides a kind of anti-tin tool that connects, and comprises frame and base plate, and it is characterized in that: said base plate is a frame type structure; Said base plate inboard is provided with accommodating groove; Said accommodating groove towards the middle part of base plate, is provided with metal swing arm and horizontal rotary mechanism along floor level setting and opening in the said accommodating groove, said metal swing arm is fixed on can do to horizontally rotate along accommodating groove in the accommodating groove through horizontal rotary mechanism and moves.The metal swing arm is located in the accommodating groove of base plate and through horizontal rotary mechanism and is rotatably connected with base plate, horizontally rotates the metal swing arm during use and makes its free end stretch to the middle part of tool, solves the position that connects the tin problem according to needs on the real dress wiring board and adjusts, and makes it and possibly connect adjacent two solder joints of tin approaching; Through the adsorption capacity of metal swing arm liquid towards tin, the absorption of the unnecessary liquid tin on the plug-in unit pin taken away prevent to be detained, thereby solve the company's tin phenomenon between the solder joint; Improve the yields of real dress wiring board, and reduce follow-up dressing operation, save manpower and time; Improve and make efficient, reduce cost, use the back because metal swing arm structure is fragile relatively; Can the rotation of metal swing arm be stowed in the accommodating groove,, increase the service life to avoid infringement; Overall structure is simple, and is very easy to use, and the company's of preventing tin is effective.
The aforesaid anti-tin tool that connects; It is characterized in that: said horizontal rotary mechanism comprises a swingle and a spring; One end of said metal swing arm is provided with through hole, and said swingle passes the through hole on the metal swing arm, and the two ends of swingle link to each other with the bottom surface with the end face of accommodating groove respectively; Also be provided with a spring between the bottom surface of said metal swing arm and accommodating groove, said spring housing is located on the swingle.Swingle passes the through hole on the metal swing arm and links to each other with the bottom surface with the end face of accommodating groove; The metal swing arm can horizontally rotate around swingle, and is simple in structure, handled easily; Spring sheathed on the swingle plays upwards top to the metal swing arm; Make the metal swing arm more near solder joint, improve adsorption effect as much as possible near the real dress wiring board of base support.
The aforesaid anti-tin tool that connects, it is characterized in that: the material of said metal swing arm can be nickel or copper.The adsorption capacity of nickel and copper liquid towards tin is all very strong, is suitable as the material of metal swing arm.
The aforesaid anti-tin tool that connects, it is characterized in that: the material of said metal swing arm is a nickel.The adsorption effect of nickel liquid towards tin is good, can be used as preferred metal swing arm material.
The beneficial effect that the utility model reached is:
Simple in structure, easy to operate, can effectively prevent the company's tin phenomenon in the wave-soldering process.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is the metal swing arm partial structurtes sketch map of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in Figure 2, the anti-tin tool that connects comprises frame 1 and base plate 2; It is characterized in that: said base plate 2 is frame type structure, and said base plate 2 inboards are provided with accommodating groove 3, said accommodating groove 3 along base plate 2 be horizontally disposed with and opening towards the middle part of base plate 2; Be provided with the metal swing arm 4 and the horizontal rotary mechanism of nickel matter in the said accommodating groove 3; Said horizontal rotary mechanism comprises a swingle 5 and a spring 6, and an end of said metal swing arm 4 is provided with through hole, and said swingle 5 passes the through hole on the metal swing arm 4; The two ends of swingle 5 link to each other with the bottom surface with the end face of accommodating groove 3 respectively; Said spring 6 is located between the bottom surface of metal swing arm 4 and accommodating groove 3, and said spring 6 is set on the swingle 5, and said metal swing arm 4 is fixed on can do to horizontally rotate along accommodating groove 3 in the accommodating groove 3 through horizontal rotary mechanism and moves.
During use; Confirm to connect easily on the real dress wiring board bond pad locations of tin earlier, rotation adjustment metal swing arm 4 makes its free end arrive predetermined absorption position, and real dress wiring board is placed on the base plate 2; Through supporting support around 2 pairs of real dress wiring boards of base plate; Because base plate 2 middle parts are provided with dead slot, can further adjust metal swing arm 4 simultaneously, make its free end accurately arrive predetermined absorption position from the back side of base plate 2; Spring 5 also can make it as much as possible near real dress wiring board on top on the metal swing arm 4; Again tool is put into the tin stove together with real dress wiring board and carry out wave-soldering and get final product, during through the liquid tin crest, because the absorption affinity of the metal swing arm 4 liquid towards tin of nickel matter is very strong; Can the unnecessary liquid tin on the plug-in unit pin of real dress wiring board be adsorbed, make two adjacent plug-in unit pin all can evenly go up tin and company's tin phenomenon does not take place.
The utility model is simple in structure, and is easy to operate, can effectively prevent the company's tin phenomenon in the wave-soldering process.
Above embodiment limits the utility model never in any form, every above embodiment is made with the equivalent transformation mode other improve and use, all belong to the protection range of the utility model.
