Description
Technical Field
The invention relates to the technical field of lead-acid storage battery assembly, in particular to an induction electric heating welding device for an end post and an end post sleeve and an automatic production line.
Background
In the assembly production process of the lead-acid storage battery, an end pole sleeve positioned on a battery cover is connected with an end pole on the battery by adopting manual or equipment open flame welding gun for welding. In the welding process, flame control is difficult, heating temperature controllability is poor, and the welding effect after welding is seriously affected.
In the conventional flame welding gun, as shown in fig. 1, in the welding process of welding the end post 42 and the end post sleeve 41, natural gas and oxygen are mixed and then burned to form flame, and the flame is mainly heated and melted, and comprises a gas mixing part 51, a flame lifting device 52 and a flame spraying device 54.
Because the welding height requirements on the two end polar posts are strict, namely, the height requirements on the two positive and negative end polar posts are consistent after welding, if the set requirements are exceeded, the whole lead-acid storage battery can be judged to be defective, and repair welding and other operations are needed in the later period. The flame in the flame welding gun is difficult to control, and the controllability of the heating temperature is poor, so that the welding height is difficult to control.
In fig. 1, it can be seen that to overcome this difficulty, a flame heating core rod 55 is provided in the center of the flame gun. When the terminal post and the terminal post sleeve are welded, the die 53 is aligned with a battery workpiece to be welded under the drive of a flame lifting device 52 such as a servo motor; then, the flame which burns after the natural gas and the oxygen are mixed heats the flame heating core rod, then the height of the flame heating core rod is reduced, and the flame heating core rod is contacted with the terminal post or the terminal post sleeve through the central hole of the die to heat, so that the terminal post and the terminal post sleeve are uniformly heated and melted; the flame heating core rod is continuously lowered until the height is set, namely, the welding height of the terminal pole is ensured by the lowering height of the flame heating core rod.
The use of the flame heating core rod can improve the qualification rate of the welded terminal post to a certain degree, but still is not high, compared with the pure flame welding. The specific reason is that: because the flame heating core rod is contacted with the surfaces of the terminal post and the terminal post sleeve, after the heating is finished, the flame heating core rod and the flame rise, and the mold is cooled and molded. However, in the rising process of the flame heating core rod, molten liquid of the terminal post and the terminal post sleeve which are not cooled is taken away, and the taking-away amount of the molten liquid is not easy to control, so that the height of a battery workpiece after welding is difficult to control, and the overall height is short.
In addition, a flame system for burning natural gas and oxygen after mixing needs a complicated gas path control system, and wiring and piping are complicated and high in requirements. Further, flame temperature, size are influenced by outside change greatly, can't guarantee invariable flame temperature and size, and factor of safety is low, has certain potential safety hazard.
