Embodiment 1
[0029] figure 1 It is a schematic diagram of an automatic welding grid before pouring busbars, figure 2 It is a schematic diagram of an automatic welded grid after pouring busbars, image 3 A schematic diagram of the production process for an automatic welding grid, Figure 4 It is a partial structural schematic diagram of the lead wire drawing forming equipment. like figure 1 , figure 2 , image 3 and Figure 4 Shown, a kind of manufacturing process of automatic welding plate grid, comprises the following steps:
[0030] a. Put the raw material of the lead pillar into the heating furnace and heat it to 170°C to 190°C, so that the raw material of the lead pillar is in a semi-liquid state;
[0031] b. Add the semi-liquid lead column raw material into the lead wire forming mold 1a, the lead wire forming mold 1a is designed with a radial input port 1b and a lead wire axis output port 1c, the semi-liquid lead column raw material passes through the The input port 1b enter...
Embodiment 2
[0037] An automatic welding grid, comprising several lead wires 1 and busbars 2; the lead wires 1 are wire-shaped objects formed by wire drawing; One end of the bus bar is vertically inserted into the cavity 31 of the bus bar mold 3 to cast a bus bar 2 connected with a plurality of lead wires 1; the plurality of lead wires 1 are vertically arranged with the bus bar 2; the plurality of installation holes 21 are arranged at equal intervals; The cross-section of the lead wire 1 is elliptical, the major axis of the cross-section is 3mm-4mm, and the minor axis is 1.8mm-2.2mm.
[0038] Through the observation of the crystal phase structure, the data shows that the density of the battery grid manufactured by the above method has been greatly improved compared with the traditional one-piece cast grid. In the actual use process, it was found that the grid made by this method The performance of the battery is improved unexpectedly, and the manufacturing method of the grid is convenient....
Embodiment 3
[0040] A battery, including the automatic welding grid described in the second embodiment, the automatic welding grid is manufactured by the manufacturing process described in the first embodiment. The inventor believes that since the grid is used in the battery as a prior art, its working principle and structure will not be described here.
