Abstract

The invention discloses a detector for a lead-acid storage battery pole plate. The detector comprises a pressure testing machine, an impedance testing instrument, probes and a data collecting and processing device, wherein the pressure testing machine comprises upright posts and a supporting device arranged on an operating platform; each upright post is provided with a pressure sensor and probes,and each pressure sensor is used for collecting the interval of the corresponding probes and the pressure value; the impedance testing instrument is connected with the probes through wires, and is used for collecting direct current resistance value or alternating current resistance value; and the data collecting and processing device is connected with the pressure testing machine and the impedancetesting instrument, and is used for collecting and processing data of the pressure testing machine and the impedance testing instrument. Under the condition that the pole plate is not damaged, the resistance values or impedance values of spots at different parts on the pole plate and the thickness of the pole plate are measured, and the compatible dispersibility, uniformity and plate thickness uniformity of the components such as active substances and various additives inside the pole plate and the uniformity among different pole plates produced through same technology are judged through results capable of quantitatively judging data discretization in standard deviation, variance, average deviation and variable coefficient manners through the data collecting and processing device.

Description

technical field [0001] The invention relates to a lead-acid accumulator pole plate tester. Background technique [0002] In the manufacturing process of lead-acid batteries, the consistency of the plate quality, that is, the uniformity of the plate, directly affects the overall performance of the finished battery. The dispersion uniformity of active substances and various additives in the mixing process is the most fundamental reason affecting the uniformity of the plate, and paste and plate coating are one of the most critical processes in the production process. [0003] There are two common mixing methods, one is to prepare additives into a suspension, and then add dilute sulfuric acid, water, etc. into the mixing machine in a certain order when mixing the paste; the other is to mix the additives directly with lead powder Mix it dry in the machine, then add dilute sulfuric acid, water, etc. to knead the paste. Due to the large difference in density between various mater...
