Description
Technical field
The present invention relates to lead-acid storage battery busbar welding technology fields more particularly to a kind of lead-acid storage battery busbar to weld
Connection device and method.
Background technology
Lead-acid accumulator whether in traffic, communication, electric power, military or in navigation, each economic field of aviation, all rises
Indispensable important function is arrived.Lead-acid accumulator has been developed as the maximum battery product of yield in the world, output
The 50% of battery industry total amount is accounted for, the 70% of rechargeable battery is accounted for, it is even American-European-Japanese to wait countries and regions most flourishing in the world,
So far also still mass production and use lead-acid accumulator.
Lead-acid accumulator generally includes battery case, battery cover and the pole group in battery case, and pole group is that plumbic acid stores
The core component of battery, if it includes the mutually overlapping positive and negative pole plate of dry plate and the demarcation strip for separating positive/negative plate, just,
Negative plate top is equipped with lug, and the lug of same polarity forms bus-bar and leading-out terminal by welding, electric current when battery discharge
Positive/negative plate, lug, bus-bar is passed sequentially through to be pooled on leading-out terminal again.
There are mainly two types of the existing bus-bar welding manners of lead-acid accumulator：
One is artificial oxygen welding modes, if first by special fixture by the plate ear of dry plate same polarity pole plate equidistantly and
It is fixed on bus-bar vertically upward and melts intracavitary, then lights welding gun and adjusts flame, then lug is melted with flame, melts simultaneously
Filler metal melts intracavitary to bus-bar, finally can form bus-bar after alloy cooling.Although this human weld's mode
The thorough fusion of lug and bus-bar may be implemented, but it is very high for the requirement of the level of skill of operating personnel, and welding quality is not
Stablize, easy tos produce rosin joint, spends phenomena such as weldering, cause consistency of internal resistance of battery poor, eventually reduce battery；Together
When due to group quantity of polar plate of poling group it is more, manual operation needs scorification lug one by one, uncomfortable so production efficiency is very low
Preferably large-scale batch production.
Another kind is automation casting welding, is first integrally put into the pole group being laminated by regulation quantity of polar plate special
It in fixture, afterwards turns over fixture and makes lug vertically downward, lug is by cutting the processing of the multiple tracks such as brush, soldering flux applying and pre- tinning
Afterwards, pole group is transferred to cast welded mold station, the lug of all positive/negative plates is inserted into simultaneously respectively contains liquid metal
In positive and negative anodes mold, lug coating metal is heated at this time carries out phase transformation from solid-state to liquid, then same with the liquid metal in mold
When cool down, be finally completed cast welding formed bus-bar.Compared to artificial cast welding, it is seen that the production efficiency of automation casting welding is higher,
But busbar cast welding quality is with lug thickness, alloy species, mold temperature, lead liquid temperature, weld interval, cooling time, leaching
Tin, lug cut the effect of brush, the use of scaling powder has close relation, need the procedure parameter controlled various, any one ring
Section error can all cause cast welding quality problems, for example temperature is excessively high, overlong time can cause lug superfusion to be even broken, temperature mistake
It is low, the time is too short, pretreatment not in place can lead to lug rosin joint, dry joint, solder skip；Corresponding this automatic cast welding machine structure also compares
More complex, fixture, mold, cast welding liquid used in cast welding are cut these consumables of brush ear, heating tube and vulnerable part and can be all added to
This, makes energy consumption greatly increase.
