Background technique

With the rapid development of battery products in our country, during the battery manufacturing process, especially in the process of manually lowering the pole group, the assembly pressure of the pole group directly affects the performance of the battery, because the active material on the plate plate is directly Adsorbed on the grid ribs, the active material expands continuously during the charging and discharging process of the battery, and due to the action of gravity, the active material must fall off, which makes the separator paper between the positive and negative plates must have a certain tension , tightly pressing the active substance so that it is not easy to fall off. If the assembly pressure of the separator paper is too high, although it plays a great role in the shedding of the active material, it may easily damage the polar plate and burst the battery case, and if the AGM separator is pressed tightly, it will cause internal damage. The density is high, the relative acid absorption is reduced, and the acid and colloid are not easy to penetrate the bottom of the battery, thus affecting the performance of the battery. In addition, usually the thickness of the separator paper is the thickness under the theoretical assembly pressure calculated according to the empirical value, but there is a certain deviation between the thickness of the plate obtained by the actual smear and the theoretical value, which makes the assembly pressure and the standard value Any discrepancy will definitely affect the performance of the battery. Therefore, how to accurately measure the assembly pressure of the battery pole group plays a vital role in the assembly of the battery, and it is imperative to invent a device that can measure the assembly pressure of the battery. .

Compared with the prior art, the utility model has the following obvious advantages:

The utility model rotates the lead screw into the lead screw nut by shaking the handle, and moves forward together against the push plate, and the push plate can transfer the thrust to the pressure plate through the pressure sensor, driving the pressure plate to move towards the detected pole group. When the pressure plate presses the tested pole group from the original expansion distance to the measured distance, the display value of the electronic display connected with the pressure sensor is the assembly pressure of the tested pole group. The utility model can accurately detect the assembly pressure of the battery pole group, and can avoid the expansion and easy falling off of the positive active material in the charging and discharging process caused by too small assembly pressure, damage to the pole plate and bursting of the battery shell due to excessive assembly pressure , The phenomenon that acid and colloid are not easy to penetrate the bottom of the battery ensures stable and reliable performance of the battery.
