A kind of electric core liquid water content test sampler
Technical field
The utility model belongs to the testing apparatus technical field, relates in particular to a kind of electric core liquid water content test sampler.
Background technology
In the manufacturing process of battery, the liquid water content of electric core need be controlled a lower level, if the liquid water content of electric core exceeds standard, then can cause the formation of battery flatulence and solid electrolyte film (SEI film) to end.
In order to test the liquid water content of electric core, need carry out the sampling of electric core earlier.Sampling method at present commonly used is: electric core (comprise positive plate, negative plate and be interval in positive plate and negative plate between barrier film) through behind the high-temperature baking, adopt instrument such as scissors manually cut out between two lugs the sample that weight is 1.0 ± 0.1g (comprise positive plate, negative plate and be interval in positive plate and negative plate between barrier film).
Concrete, this method can be divided into following steps and be described: the first step, from oven, take out electric core, and remove the outer packaging film.
Second step, the sampling empty bottle of weighing, cutting out the rectangular and weight of sheet with instruments such as scissors between two lugs is the sample of 1.0 ± 0.1g.
In the 3rd step, the sample that second step was obtained carries out the liquid water content test.
Because be not used for the sampler of electric core liquid water content test in the prior art, and can only adopt the electric core of hand cutting, the electric core product that obtain are placed in the sampling jar again.This method that does not adopt sampler and adopt manual mode to obtain sample causes the inefficacy of liquid water content specimen easily, this be because: first, the cutting sample size is operated control by the people fully, randomness is bigger, need repeatedly weigh and just can reach the example weight of regulation, overlong time in the collected specimens process, sample ambient water content can change, and influences test result.
The second, sampling is shaped as the sheet rectangle, and when length surpassed 2/3 place of sampling jar, the liquid water content test accuracy descended, and this mainly is because sample moisture can not be displaced when test fully.
The 3rd, the electric core less for size and thickness is thinner, electricity core diverse location liquid water content basically identical, but for the bigger and thicker electric core of electric core size, because concentrate the sample position, the result who adopts this sampling method sampling to carry out the liquid water content test can not represent the liquid water content value of whole electric core.
The 4th, different employees' mode of operation is different, and the sampling speed relies on employee's proficiency fully.
In view of this, necessaryly provide a kind of electric core liquid water content test sampler, this sampler can effectively shorten sample time and liquid water content test duration, thereby improve the efficient of electric core liquid water content test, can eliminate simultaneously human factor and extraneous factor to the influence of test, improve accuracy of test.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, use sampler and provide a kind of electric core liquid water content to test, this sampler can effectively shorten sample time and liquid water content test duration, thereby improve the efficient of electric core liquid water content test, can eliminate simultaneously human factor and extraneous factor to the influence of test, improve accuracy of test, test inaccurate deficiency to overcome in the prior art sample time long, liquid water content.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of electric core liquid water content test sampler, comprise back up pad, be used for to place punched-plate, guide groove, the sampling jar of electric core and be used for the drift of punching, described punched-plate is fixedly connected on described back up pad, described guide groove is fixedly connected on described punched-plate below, and described sampling jar is fixedly set in described guide groove.
As a kind of improvement of the utility model electricity core liquid water content test with sampler, described sampler also comprises base plate, and described back up pad is fixedly connected between described base plate and the punched-plate.
As a kind of improvement of the utility model electricity core liquid water content test with sampler, described punched-plate is bolted in described back up pad.
As a kind of improvement of the utility model electricity core liquid water content test with sampler, being shaped as of the through hole on the described punched-plate is square, circular, triangle or ellipse.
As a kind of improvement of the utility model electricity core liquid water content test with sampler, described sampling jar is connected in described guide groove.
As a kind of improvement of the utility model electricity core liquid water content test with sampler, described guide groove be shaped as U-shaped.
As a kind of improvement of the utility model electricity core liquid water content test with sampler, described back up pad is welded in described base plate.
With respect to prior art, the utility model has the following advantages at least: first, the size of cutting sample is determined by the size of through hole on drift and the punched-plate, thereby elimination artificial factor, and can reach the example weight of regulation in the short period of time, therefore the time lacks (practice shows, shortens to of the prior art 40% sample time) in the process of collected specimens, the variation of sample ambient water content is less to its influence, thereby improves accuracy of test.
Second, the sampling shape is various, and the size of sample is less, sample moisture can be displaced when test fully, effectively shorten the liquid water content test duration (practice shows, the liquid water content test duration shorten to prior art 60%), improve the liquid water content accuracy of test, feed back the baking state of production line fast, promote the utilization factor of baking box.
The 3rd, the utility model sample position relatively disperses (spreading all over whole electric core), and the result that these samples are carried out liquid water content test can represent the liquid water content value of whole electric core.
The 4th, in the utility model, sampling jar is fixed in the guide groove, and guide groove is positioned at the below of punched-plate, and the sample of going out can directly be fallen in the sampling jar, can avoid moisture in the external environment to the influence of sample.
