Ear is located at the side of pole group top surface, and the tab of all negative plates is located at the other side of pole group top surface, between homopolarity tab by with
Busbar cast welding is connected.
Generally need solder type first in cast welded mold is intracavitary to fill lead liquid, then by pole group's tab insertion solder type it is intracavitary into
Row welding；Then leading to cooling water in cast welded mold cools down lead liquid, and lead liquid is during cooling and solidifying, i.e., by pole group's
Tab row's cast welding is integral, finally further takes out pole group.
In response to national clean manufacturing, the requirement of intelligence manufacture and machine substitute human labor, electric road vehicle battery is at present
Automatic cast welding is converted to from manual welding successively, because positive plate lugs thickness difference is larger, positive and negative tab is needed in welding
Different heats requires height to cast welded mold, completes cast welding under same mold, be easy to cause welding quality unstable, different
It causes.
The major defect of traditional approach:
(1) after tab glues scaling powder, the aqueous or oiliness scaling powder of storage free state is easy on tab, when tab is inserted
Enter to after cast welded mold, because lead liquid temperature is high, be easy to cause the water of the inside, generate bubble, seriously affected busbar connector
Welding quality, be easy to cause in busbar connector and form stomata, accelerate the corrosion of busbar connector.
(2) positive plate lugs thickness is than cathode plate thickness, without prior preheating, be easy to cause positive plate falseness weld or
The superfusion of person's negative lug.
