Problems solved by technology

The process of testing the apparent density of the lead paste used in the current production process: artificially take samples at different positions of the lead paste, make the sample into a cylindrical shape by hand pinching, put it into a cylindrical measuring cup and tamp it down, and scrape off the excess lead paste with a scraper Remove it, this method of sample preparation is greatly affected by human factors, different hand pinching and scraping lead plaster methods will cause deviations in results, and the large fluctuations in the results of the lead paste apparent density process will directly affect the quality of the lead plaster

Embodiment 1

[0038] A lead-acid battery apparent density test lead paste sampling test tool, such as figure 1 , 2 , 3, including sampler 1, sample carrier 2 and scraper 3,

[0039] The sampler 1 includes a body 4, a cover plate 5, and a fixing member 6 for cooperating and fixing the cover plate 5 and the body 4; the body 4 is matched with the cover plate 5 to form a circular tube shape, and the fixing member 6 is sleeved on the cover plate 5 The junction with the body 4 is used to fix the two;

[0040] The scraper 3 is used to scrape off excess samples in the sample carrier 2.

[0041] The body 4 includes a gripping portion 7 at the rear and a matching portion 8 at the front that fits with the cover plate 5 . The gripping portion 7 is in the shape of a round tube, and the fitting portion 8 cooperates with the cover plate 5 to form a round tube shape.

Embodiment 2

[0043] Make further improvement on the basis of embodiment 1, as Figure 4 section, as follows:

[0044] The cross-section of the cover plate 5 gradually increases from the front end to the rear end, that is to say, the contact line between the cover plate 5 and the body 4 gradually slopes downward from the front end to the rear. Such an arrangement can facilitate the filling of the body 4 and the cover plate 5 with lead paste Finally, for the disassembly of the cover plate 5.

Embodiment 3

[0046] Make further improvement on the basis of above-mentioned embodiment; Figure 4 with Figure 5 As shown, the details are as follows:

[0047] A discharge bump 9 is provided at the joint between the rear part of the cover plate 5 and the matching portion 8 , and the fitting portion 8 is provided with a discharge inner concave portion 10 matched with the discharge bump 9 . On the one hand, the discharge projection 9 can form a clamping connection with the discharge inner recess 10 to form a fixing effect on the cover plate 5. When the tool is inserted into the lead paste, it cooperates with the fixing member 6 to form the cover plate 5 and the body 4 into one Overall; at the same time, on the other hand, the structure of the discharge bump 9 and the discharge inner recess 10 can be used to facilitate the removal of the cover plate 5, which can reduce the adhesion of the lead paste to the cover plate 5 and prevent the removal of the cover plate 5 During the process, the l...

Abstract

The invention relates to the technical field of storage battery test, in particular to a lead paste sampling testing tool and a testing method for testing the visual density of lead acid storage batteries. The lead paste sampling testing tool comprises a sampler, a sample carrier and a scraper, wherein the sampler comprises a body, a cover plate and a fixing member which is used for matching and fixing the cover plate and the body; the body is matched with the cover plate to form a circular tube shape, the fixing member is sleeved at a joint of the cover plate and the body and is used for fixing the two members; the scraper is used for scraping off the excess sample from the sample carrier. According to the lead paste sampling testing tool and testing method for testing visual density of lead acid storage battery, the tool is convenient to sample, and a sample can be taken out of the lead paste directly in a certain shape for testing; and after the sample is taken out, the sample can be easily removed without damaging the initial formation of the sample, thereby the sample can be transferred to the sample carrier for tamping for further testing.

Description

technical field [0001] The invention relates to the technical field of battery detection, in particular to a lead paste sampling test tool and a test method for the apparent density test of a lead-acid battery. Background technique [0002] Lead-acid batteries have been invented for more than 150 years. Driven by the development of automobile, transportation and communication industries, the production and market of lead-acid batteries have increased rapidly, and the vigorous development of information technology has also created a large demand for batteries. Lead-acid batteries have high cost performance, high safety reliability and recyclable characteristics, and have become an indispensable power source for human life at this stage. [0003] With the continuous improvement of the cycle performance requirements for power lead-acid batteries and the specific requirements for the initial performance of related aspects, in addition to improving the test performance by improvi...
