Description
Technical field
The present invention relates to lead-acid storage battery busbar welding technology field, particularly relate to a kind of lead-acid storage battery busbar weldering
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
Arrive indispensable important function.Lead-acid accumulator has been developed as the battery product that yield is maximum in the world, volume of production
Account for the 50% of battery industry total amount, account for the 70% of rechargeable battery, even if the countries and regions that American-European-Japanese grade is the most flourishing,
The most a large amount of productions and use lead-acid accumulator.
Lead-acid accumulator generally includes battery case, battery cover and the pole group being located 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 tablet and for separating the demarcation strip of positive/negative plate, just,
Negative plate top is provided with lug, and the lug of same polarity forms bus-bar and lead-out terminal, electric current during battery discharge by welding
Pass sequentially through positive/negative plate, lug, bus-bar to be pooled to again on lead-out terminal.
Lead-acid accumulator existing bus-bar welding manner mainly has two kinds:
One is artificial oxygen welding mode, if first pass through special fixture by the plate ear of dry tablet same polarity pole plate equidistantly and
It is fixed on bus-bar vertically upward and melts intracavity, then light welding gun and adjust flame, then melting lug with flame, melting simultaneously
Filler metal melts intracavity to bus-bar, finally can form bus-bar after alloy cools down.Although this human weld's mode
Can realize the thorough fusion of lug and bus-bar, but the level of skill for operator requires the highest, welding quality is not
Stable, easily produce rosin joint, cross the phenomenons such as weldering, cause consistency of internal resistance of battery poor, eventually reduce battery；With
Time due to the quantity of polar plate of composition pole group more, manual operation needs scorification lug one by one, so production efficiency is the lowest, uncomfortable
The most large-scale batch production.
Another kind is automatization's casting welding, first puts into special by the pole group entirety good by regulation quantity of polar plate stacking
In fixture, afterwards turning over fixture and make lug vertically downward, lug is through cutting at the multiple tracks such as brush, soldering flux applying and pre-tinning
After reason, pole group transferring to cast welded mold station, the lug of all positive/negative plates is inserted simultaneously into respectively containing liquid lead alloy
Both positive and negative polarity mold in, now lug coating metal is heated and is carried out phase transformation by solid-state to liquid, then with the liquid metal in mold
Cool down simultaneously, be finally completed cast welding and form bus-bar.Compare artificial cast welding, it is seen that the production efficiency of automatization's casting welding is relatively
Height, but busbar cast welding quality with lug thickness, alloy species, mold temperature, lead liquid temp, weld interval, cool time,
Wicking, lug cut the effect of brush, the use of scaling powder has close relation, need the procedure parameter controlled various, any one
Link is made mistakes and all can be caused that cast welding quality problems, such as temperature are too high, overlong time can cause lug superfusion even to be ruptured, temperature
Too low, the time is too short, pretreatment meeting not in place causes lug rosin joint, dry joint, solder skip；Corresponding this automatic cast welding machine structure is also
More complicated, fixture, mould, cast welding liquid used by cast welding, cut brush ear, add these consumable goodss of heat pipe and consumable accessory all can increase into
This, make energy consumption be greatly increased.
