具体实施方式detailed description
下面结合具体附图对本发明做进一步描述。The present invention will be further described below with reference to the specific drawings.
如图1、2所示，本发明铅酸蓄电池包括电池壳体1，放置在电池壳体1的极群2，极群2和极板组成，极板上具有极耳3，将极耳进行连接的汇流排10。As shown in Figures 1 and 2, the lead-acid battery of the present invention comprises a battery case 1, a pole group 2 placed in the battery case 1, the pole group 2 and a pole plate are formed, and the pole plate is provided with a pole lug 3, and the pole lug is carried out. Connected busbars 10 .
如图3所示，模具4包括模具壳体5，壳体5内设置有空腔6，空腔6用于接收待焊接本体，待焊接本体如极群2， 空腔6内用于接收液态铅7，液态铅可以通过注入口20注入，也可以将模具沉入液态铅内的方式来实现。模具4的壳体5上形成有正电连接端口8和负电连接端口9，正电连接端口8和负电连接端口9可与液态铅形成电连接，正电连接端口8和负电连接端口9对外通过导线与外部电源进行电连接。As shown in FIG. 3, the mold 4 includes a mold shell 5, and a cavity 6 is provided in the shell 5. The cavity 6 is used to receive the body to be welded, such as the body to be welded, such as the pole group 2, and the cavity 6 is used to receive liquid. Lead 7, the liquid lead can be injected through the injection port 20, or the mold can be immersed in the liquid lead. A positive electrical connection port 8 and a negative electrical connection port 9 are formed on the shell 5 of the mold 4. The positive electrical connection port 8 and the negative electrical connection port 9 can form an electrical connection with the liquid lead, and the positive electrical connection port 8 and the negative electrical connection port 9 pass through to the outside. The wires are electrically connected to an external power source.
如图4所示，一种铅酸蓄电池的极板连接方法，包括下列步骤，在模具4空腔6内注入液态铅7；将极群2的极耳3深入模具4空腔6内(为图4中可显示出液态铅7，图中极耳3尚未深入到空腔6的底部)；将壳体5上的正电连接端口8和负电连接端口9通过导线外接电源(图中未显示)，模具4的空腔6内的液态铅进行通电，此时与液态铅融合的极耳通过电流以及通过电流的极耳表面电阻大，使得通过电流的极耳温度上升，极耳表面的氧化铅、硫酸铅会从极耳表面脱落，这样有利于液态铅与极板的极耳融合焊接，另外由于氧化铅、硫酸铅的密度低于液体铅，最终将漂浮在液态铅表面；断开外接电源；待所述液态铅冷却并与极耳凝固后，对模具4进行脱模。氧化铅、硫酸铅最终会形成在液态铅冷却后形成的汇流排的表面，对导电基本没有影响。本发明的一种铅酸蓄电池的极板连接方法，也可以先将极群的极耳深入模具内，再在模具内注入液态铅，形成通电，也可以实现本发明的目的。本发明也可以在模具4空腔6内注入液态铅7时，即对模具4的空腔6内的液态铅形成通电，这样可以保持液 态铅的温度，当极耳深入液态铅后，加快极耳表面氧化铅、硫酸铅的处理。As shown in FIG. 4 , a method for connecting a pole plate of a lead-acid battery includes the following steps: injecting liquid lead 7 into a cavity 6 of a mold 4; The liquid lead 7 can be shown in FIG. 4, the tabs 3 have not yet penetrated into the bottom of the cavity 6); connect the positive electrical connection port 8 and the negative electrical connection port 9 on the housing 5 to an external power supply through wires (not shown in the figure). ), the liquid lead in the cavity 6 of the mold 4 is energized, at this time the electrode lug fused with the liquid lead passes the current and the electrode surface resistance of the current through the current is large, so that the temperature of the electrode through the current rises, and the oxidation of the surface of the electrode Lead and lead sulfate will fall off from the surface of the tab, which is conducive to the fusion and welding of liquid lead and the tab of the electrode plate. In addition, because the density of lead oxide and lead sulfate is lower than that of liquid lead, they will eventually float on the surface of liquid lead; disconnect the external connection Power supply; after the liquid lead is cooled and solidified with the tabs, the mold 4 is demolded. Lead oxide and lead sulfate will eventually form on the surface of the busbar formed after the liquid lead is cooled, and have little effect on electrical conductivity. In the method for connecting the pole plates of a lead-acid battery of the present invention, the tabs of the pole group can also be penetrated into the mold first, and then liquid lead is injected into the mold to form electricity, which can also achieve the purpose of the present invention.

In addition, since the weight of the mold is much lighter than the weight of the body to be welded, such as the pole group, the way for the pole lugs 3 of the pole group 2 of the present invention to penetrate into the cavity 6 of the mold 4 is preferably the mold 4 to the pole group 2. The direction of the tabs 3 is moved. In addition, in order to prevent liquid lead from dripping onto the body to be welded, such as the pole group, during welding, the mold 4 is preferably located below the tabs 3 of the pole group 2. Of course, the way that the tabs 3 of the pole group 2 of the present invention go deep into the cavity 6 of the mold 4 can also be that the mold 4 moves from the upper direction toward the tabs 3 of the pole group 2.
