Problems solved by technology

[0003] The disadvantage of the current solution is that when the liquid is pumped and injected, because the internal pressure of the battery is lower than the external pressure of the battery case, the battery case will shrink and deform inwardly. The plate is compressed more tightly, which will affect the smoothness of liquid injection and make the distribution of electrolyte in the electrode group uneven, especially when repeated pumping operations are required, the impact is more obvious
At the same time, when the vacuum is too large, this inward contraction force will also damage the separator and make it lose part of its elasticity, which will affect the performance of the battery

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the specific embodiments of the accompanying drawings.

[0015] Such as figure 2 , 3 , Shown in 4, lead-acid battery liquid injection device of the present invention comprises bracket 7, liquid injection port 6, workbench 11, and workbench 11 is provided with battery positioning baffle plate 9 and the groove 10 that is used for strengthening sealing effect. The liquid injection port 6 is installed on the bracket 7, the bracket 7 includes a moving cover, and a sealing rubber pad 8 is arranged on the lower end surface of the moving cover. The working process of this battery vacuum liquid injection device is: put the battery 5 into the battery positioning baffle 9 of the workbench 11, start the liquid injection program, and move the mobile cover downward to reach image 3 state, the sealing rubber pad 8 on the mobile cover is in close contact with the groove 10 on the workbench 11 to seal the batt...

Abstract

A liquid injection device for lead-acid battery provided by the invention comprises a bracket, a liquid injection port installed on the bracket and a work table for placing a storage battery, whereinthe bracket forms a sealed space with the work table, the storage battery is arranged in the sealed space, a part of the liquid injection port is connected with an acid addition port of the storage battery, and another part of the liquid injection port is arranged in the sealed space. The lead-acid battery liquid injection device of the invention can ensure that the internal and external vacuum degree of the battery is appropriate and the liquid injection is smooth.

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a liquid injection device for a lead-acid storage battery. Background technique [0002] At present, EVF series lead-acid batteries use conventional acid addition methods when adding acid in liquid injection production, such as attached figure 1 As shown, the conventional acid adding device is composed of a liquid injection port 1, a bracket 2, and a workbench 4. There is a stopper 3 for battery positioning on the workbench. When the lead-acid battery is filling the electrolyte, put the battery 5 into the working Inside the positioning stopper 3 on the platform 4, the bracket 2 moves downwards, driving the liquid injection port 1 to connect with the battery liquid injection hole to achieve figure 2 state, the upper end of the liquid injection port 1 is connected to the vacuum station of the liquid injection equipment and the electrolyte storage tank. After the connection is comple...
