Heating device for bus-bar manufacturing

Abstract

The invention relates to the field of battery manufacturing, in particular to a heating device for bus-bar manufacturing. According to the technical scheme, the heating device for bus-bar manufacturing comprises a die; the die comprises molding grooves, the heating device further comprises a heat supply assembly, and the heat supply assembly comprises a constant-temperature heat supply assembly body used for stably and continuously providing heat for the die and a fast heat supply assembly body used for heating the die fast; and the fast heat supply assembly body is connected with the die through heating channels arranged in the die. The heating device for bus-bar manufacturing does not need to be soaked in a lead pot in the heating process, lead residue generation is avoided, the heating device comprises the constant-temperature heat supply assembly body and the fast heat supply assembly body, and molten lead treatment heat efficiency is high.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to a bus bar manufacturing heating device. Background technique [0002] In the battery industry, especially the lead-acid battery industry, commonly used parts include tabs and matching busbars. In the traditional manufacturing process of busbars, it is necessary to prepare busbar molds and lead pots. For example, the publication number is CN103268963A An internalized storage battery manufacturing process announced by the Chinese Invention Patent Document requires that the mold be placed in the lead pot and flow into the busbar at high temperature, but there are certain problems in this method: first, the large-capacity lead pot needs to be continuously In the heating state, energy consumption is large; secondly, during the heating process, the outer surface of the mold is higher than the inner surface of the mold, resulting in low energy efficiency and waste of heat sources; f...

[0002] In the battery industry, especially the lead-acid battery industry, commonly used parts include tabs and matching busbars. In the traditional manufacturing process of busbars, it is necessary to prepare busbar molds and lead pots. For example, the publication number is CN103268963A An internalized storage battery manufacturing process announced by the Chinese Invention Patent Document requires that the mold be placed in the lead pot and flow into the busbar at high temperature, but there are certain problems in this method: first, the large-capacity lead pot needs to be continuously In the heating state, energy consumption is large; secondly, during the heating process, the outer surface of the mold is higher than the inner surface of the mold, resulting in low energy efficiency and waste of heat sources; finally, because such a process requires the mold to be soaked in the lead pot In the middle, the lead liquid in the mold bubbles under the action of boiling, and the lead slag is much

On the other hand, busbars need to heat up and cool down the mold during the production process. After cooling down, the heating speed is slow and the efficiency is low, which not only consumes resources but also affects the speed of finished products.
