Embodiment 1

[0032] See Figures 1 through 3 、 Figures 7 through 9, a kind of 2×3 structure battery bus welding mold of the present invention, comprising a first welding module 10, a second welding module 20, the first welding module 10 comprising an A comb mold 1, two B comb molds 2, and may be combined with A comb mold 1, two B comb molds 2 clamping three top molds 4, the second welding module 20 comprises a C comb mold 3, two B comb molds 2, and may be combined with C comb mold 3, two B comb mold 2 molds 4, respectively; The A comb die 1 is provided with two first type cavity grooves 11, between the two first type grooves 11 is provided with a first barrier boss, the first type cavity groove 11 has a terminal positioning groove 12 for accommodating terminals; The B comb die 2 is provided with two second type cavity grooves 21, two second type cavity grooves 21 are provided with a second barrier boss; The C comb die 3 is provided with a third type cavity 31, each top die 4 for plugging the op...

Embodiment 2

[0041] See Figures 4 through 6 The difference between the present embodiment and Example 1 is that: when the two B comb molds 2, A comb mold 1 and the top mold 4 of the first welding module 10 are combined, respectively, the position corresponding to the second row, the fourth row, and the sixth row of polar ears of the battery is formed in a welding cavity (corresponding Figure 5 In the position of 200, 400, 600), the second welding module 20 of the C comb mold 3, two B comb molds 2 and the top mold 4 when the mold is combined, respectively, in the first row of the battery, the third row, the fifth row of polar ears corresponding to the position to form a welding cavity (corresponding Figure 6 The position of the labels in 100, 300, 500).

[0042] The method of using the above mold to achieve battery welding includes the following steps:

[0043] S1. The battery is formed by two B comb molds 2 and top mold 4, A comb mold 1 and top mold 4 in the first station to form multiple prim...

Abstract

The invention provides a welding die and a welding method for a storage battery busbar of a 2 * 3 structure, and the welding method comprises the following steps: S1, a plurality of primary welding cavities are formed by closing two comb dies B and a top die and closing a comb die A and the top die at a first station of a battery, and part of tabs are welded into the busbar through a welding gun; s2, the battery is converted to a second station, a plurality of secondary welding cavities are formed through die assembly of the C comb die and the top die and die assembly of the two B comb dies and the top die, and then the remaining tabs of the battery are welded into a busbar through the welding gun; when the step S1 and the step S2 are welded or only the step S2 is welded, the busbar gap bridge and the busbar are welded into a whole at the same time, and the two groups of busbars corresponding to the second row of tabs and the third row of tabs of the battery and the two groups of busbars corresponding to the fourth row of tabs and the fifth row of tabs of the battery are connected. According to the invention, step-by-step welding is adopted and the bus-bar gap bridge is added, so that the welding of the bus-bar with a complex structure is realized, the streamline automatic operation can be arranged, the unmanned automatic welding is realized, and the labor cost is greatly reduced.

Description

【Technical field】 [0001] The present invention relates to the technical field of battery welding, in particular a 2×3 structure battery bus welding die and welding method thereof. 【Background】 [0002] Lead-acid batteries are generally made up of multiple single cells in series, generally for adjacent 6 single cells in series, known as 1X6 structure, there are also 3 adjacent single cells in series, and then the two groups of 3 single cells are connected together to form a battery, called 2×3 structure batteries. [0003] Among them, the 1X6 structure battery adopts a high-current discharge welding method, and the market has begun to apply. 2×3 structure battery because of its structural particularity, the use of high current welding has not yet been specific performance, now proposed a 2×3 structure battery bus welding mold and its welding method. 【Contents of the Invention】 [0004] Object of the present invention is to solve the problems in the prior art, to propose a 2×3 str...
