Electronic detector for pressure of accumulator polar group

Abstract

The invention discloses an electronic detector for the pressure of an accumulator polar group. A front fixed plate and a rear fixed plate which are mutually parallel are arranged at both ends of a base supporting plate; a pressing plate and a pushing plate are arranged in parallel between the front fixed plate and the rear fixed plate, two guiding posts are respectively arranged at both sides of the front fixed plate and the rear fixed plate, transversally penetrate through the pressing plate and the pushing plate and are fixedly connected with the front fixed plate and the rear fixed plate; a pressure sensor is arranged between the pressing plate and the pushing plate, one end of the pressure sensor is vertically fixed in the center of the pressing plate, the other end of the pressure sensor contacts with the pushing plate; an electronic monitor is connected with the pressure sensor to display the pressure value of the pressure sensor; a screw nut is fixed in the center of the rear fixed plate, one end of the screw is connected with a crank, and the other end of the screw is screwed in the screw nut, abuts the pushing plate and moves forwards. The invention can accurately measure the assembly pressure of the accumulator polar group and ensure the stable and reliable performance of the accumulator.

Description

technical field [0001] The invention relates to a valve-controlled lead-acid storage battery, in particular to a detection device for the battery pole group pressure. Background technique [0002] 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 sh...

Problems solved by technology

[0003] The purpose of the present invention is to provide an electronic detector for battery pole group pressure, which can accurately measure the assembly pressure of the battery, so as to solve the problem of expansion of the positive active material during the charging and discharging process caused by the excessive or too small assembly pressure in the prior art It is easy to fall off, damage the plate and burst the battery shell, acid and colloid are not easy to penetrate the bottom of the battery and affect the performance of the battery
