Abstract
The utility model relates to the technical field of anti-thunder modules, in particular to a double-chip anti-thunder module reflow soldering tool which comprises an upper module, a lower module and a supporting foot structure fixed together through a butterfly-shaped bolt. Two supporting feet of the supporting foot structure are provided with an aluminum alloy rocker arm pressing head and a torsional spring respectively to form a self-clamping clamp.
Description
Technical field
The utility model relates to lightning-protection module technical field, is specifically related to dual chip lightning-protection module Reflow Soldering welding tooling.
Background technology
The working method of traditional dual chip lightning-protection module low temperature solder joint Reflow Soldering welding tooling, the general structural design that all adopts steel screw in compression low temperature solder joint, as shown in Figure 1.This design has been very ripe technology, the Reflow Soldering welding of the dual chip of extensive use simultaneously lightning-protection module low temperature solder joint, but in long-term use procedure, find that this welding manner has two defects: 1, to have determined that the holding screw size of traditional frock can not design too large due to product structure, therefore holding screw is all smaller, this has just caused operator's occasional to forget that tight screw just puts into product Reflow Soldering equipment, causes defective work; 2, in order to improve the service life of frock, traditional frock holding screw is all steel screw, this just causes a kind of drawback, steel screw is because its material behavior is all easily inhaled tin, cause the scolding tin of welding position likely by screw, to be adsorbed, thereby cause failure welding, so existing welding tooling can not meet the demands obviously.
Meanwhile, the eutectic welding means of spot welds quality of dual chip lightning-protection module is one of most important performance indications of dual chip lightning-protection module.At present, because eutectic welding means of spot welds quality is unstable, causing usually appears in existing dual chip lightning-protection module does not thread off or the bad phenomenon such as improper dropout.
For solving the aforementioned problems in the prior, the utility model provides a kind of new solution.
Summary of the invention
The purpose of this utility model is to provide Novel welding frock, and this tool structure is simple, and clamping is quick, also can guarantee the reliability of welding simultaneously, and is easy to a kind of dual chip lightning-protection module Reflow Soldering welding tooling of manufacture in batches.
The present invention is to achieve these goals by the following technical solutions:
A kind of dual chip lightning-protection module Reflow Soldering welding tooling, it is characterized in that: comprise upper module and lower module, described upper module and lower module, by the wing bolt formation stand bar structure that is fixed together, are respectively arranged with Aluminum Rocker Arm pressure head and torsion spring and form from grip jaw on two legs of described stand bar structure.
In such scheme, described torsion spring material selection I class silicon-manganese spring steel 60Si2MnA.
In such scheme, Aluminum Rocker Arm pressure head is selected fine aluminum alloy 5052.
The present invention has following beneficial effect:
One, clamping is quick, accurate positioning;
Two, solder joint crimping position is reproducible, enhances productivity and welding quality, is embodied in:
Pressure head is pressed on soldering part 1 spring leaf under the effect of torsion spring, after moving contact slipper downwards, spring leaf guaranteed certain gap all the time and between soldering part 2 chips, this gap can fully be filled scolding tin, by the firm linking springs sheet of scolding tin and chip, because the gap between spring leaf and chip has unanimously guaranteed the consistent of soldering tin amount, therefore guaranteed the dropout uniformity that it is good, and before with screw when firm, the bad control of its Tightening moment, thereby cause the gap between spring leaf and chip inconsistent, the soldering tin amount of its filling is also inconsistent, therefore its dropout uniformity is poor,
Three, avoided human factor to leak tight screw and produced waste product.
Accompanying drawing explanation
Fig. 1 is conventional module reflow soldering frock;
Fig. 2 is the module reflow soldering frock of utility model;
Wherein, 1, torsion spring; 2, Aluminum Rocker Arm pressure head; 3, butterfly screw rod; 4, upper module; 5, lower module 6, steel holding screw.
The specific embodiment
The utility model provides a kind of dual chip lightning-protection module Reflow Soldering welding tooling, it is characterized in that: comprise upper module and lower module, described by the wing bolt formation stand bar structure that is fixed together, on two legs of described stand bar structure, be respectively arranged with Aluminum Rocker Arm pressure head and torsion spring and form from grip jaw.
Torsion spring material selection I class silicon-manganese spring steel 60Si2MnA, this spring steel elastic limit is high, good mechanical properties, stressed cycle-index is greater than 1000000 times.
Rocking arm pressure head is selected fine aluminum alloy 5052, this material has and has good shaping processability energy, corrosion stability, with medium static strength, most critical be that aluminium alloy is not inhaled tin, guaranteed the solderability of module low temperature solder joint, guarantee welding quality.
After product is placed between upper and lower module, at the effect lower shake-changing arm pressure head of torsion spring, automatically push down module low temperature solder joint, avoided the fastening phenomenon of leakage of artificial trip bolt.
Solder joint crimping position is reproducible, enhances productivity and welding quality, is embodied in:
Aluminum Rocker Arm pressure head is pressed on soldering part 1 spring leaf under the effect of torsion spring, after moving contact slipper downwards, spring leaf guaranteed certain gap all the time and between soldering part 2 chips, this gap can fully be filled scolding tin, by the firm linking springs sheet of scolding tin and chip, because the gap between spring leaf and chip has unanimously guaranteed the consistent of soldering tin amount, therefore guaranteed the dropout uniformity that it is good, and before with screw when firm, the bad control of its Tightening moment, thereby cause the gap between spring leaf and chip inconsistent, the soldering tin amount of its filling is also inconsistent, therefore its dropout uniformity is poor.
