The testing tool is characterized that a sliding block is also included, wherein two sides of the sliding block are provided with a fixed block and a cylinder respectively, the bottom of the sliding block is arranged on a guide rail, and the cylinder can push the sliding block to move along the guide rail; and one of the anode probe and the cathode probe is fixedly arranged on the fixed block, the other probe is fixedly arranged on the sliding block, and the anode probe and the cathode probe share the same axis. The testing tool has simple structure, and is convenient to operate and favorable for improving the testing efficiency and the testing accuracy in the production process.
Description
Technical field
The utility model relates to battery and makes technical field of tooling clamps, especially relates to a kind of battery cover internal resistance testing tool.
Background technology
In cylindrical lithium ion battery is produced, the contact resistance of various piece there is very high requirement, the especially internal resistance of battery cover itself, because the structure more complicated of battery cover, the internal resistance that causes battery cover is instability more.If can not be effectively the internal resistance of battery cover be effectively detected, can produce great influence to battery quality, and existing checkout equipment and detection method are cumbersome time-consuming, need screw is fastening when measuring battery, also will manually probe be clamped battery cover measures, very loaded down with trivial details, so can only inspect by random samples, can't adapt to and carry out extensive full inspection in the production.Main is that the measurement of contact resistance and pressure dependence that battery cover itself is fixed are very big, and pressure is big more, and measured value is more little, and present method of testing is often because the excessive measured value that causes of bed knife can't embody the real internal resistance value of battery cover.Therefore, be badly in need of a kind of effective reliable battery lid and detect frock and detection method, the internal resistance of battery cover is detected entirely.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of battery cover internal resistance testing tool, and is simple in structure, easy to operate, help to improve the testing efficiency in the production run and the accuracy of test.
For achieving the above object, the utility model is by the following technical solutions: a kind of battery cover internal resistance testing tool of the present utility model, comprise anodal probe and negative pole probe, it is characterized in that: also comprise a sliding shoe, the both sides of this sliding shoe are provided with a fixed block and a cylinder respectively, the sliding shoe bottom is arranged on the guide rail, and cylinder can promote sliding shoe and move along guide rail; One of them probe stationary of described anodal probe and negative pole probe is arranged on the described fixed block, and another probe stationary is arranged on the sliding shoe, and the axis of anodal probe and negative pole probe is positioned on the same axis.
The beneficial effects of the utility model are: the utility model is fixed block or the sliding shoe of the positive and negative electrode probe stationary that is used for the internal resistance detection in corresponding setting, sliding shoe can move at the promotion lower edge of cylinder guide rail, therefore the space of placing battery cover between the positive and negative electrode probe can be regulated, can be adapted to measure battery cover, improve the utilization ratio of testing tool itself without model; During use, can realize taking battery cover to measure on the other hand on the other hand, simplify measuring method, realize the full requirement of examining of the battery cover internal resistance of producing, help improve production efficiency and product quality; Because cylinder is exerted pressure when measuring, pressure stability and pressure between the probe are less, and the data of internal resistance test are more accurate.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following instructions and the accompanying drawing.
Description of drawings
Fig. 1 is existing battery cover internal resistance testing tool structural representation.
Fig. 2 is a battery cover internal resistance testing tool structural representation of the present utility model.
Embodiment
As shown in Figure 1, existing battery cover internal resistance testing tool in use, battery cover 4 is clamped between punch 5 and the die 3, holding force provides by bolt 2, battery cover 4 picks and places inconvenience, and holding force is too big, and the dynamics when at every turn manually screwing bolt 2 is difficult to control, therefore holding force is also unstable, and the internal resistance data of the battery cover 4 that probe 1, probe 6 two ends tests obtain are also inaccurate.
As shown in Figure 2, battery cover internal resistance testing tool of the present utility model comprises anodal probe 1 and negative pole probe 4 and a sliding shoe 5, the both sides of this sliding shoe 5 are provided with a fixed block 2 and a cylinder 6 respectively, the bottom of sliding shoe 5 is arranged on the guide rail, and cylinder 6 can promote sliding shoe 5 and move along guide rail; Described anodal probe 1 is fixedly set on the described fixed block 2, and negative pole probe 4 is fixedly set on the sliding shoe 5, and the axis of anodal probe 1 and negative pole probe 4 is positioned on the same axis.During use, cylinder 6 promotes sliding shoe 5 and moves to fixed block 2 along guide rail, anodal probe 1 and negative pole probe 4 are mutually near also battery cover to be measured 3 being clamped, measurement is over only to be needed cylinder 6 is resetted, and negative pole probe 4 just can move easily and open, and the distance between the both positive and negative polarity probe is drawn back, put into new battery cover, drive cylinder again, compress battery cover, just can measure once more.Advantage of the present utility model is: the both positive and negative polarity probe has the location, and the cylinder snap-in force is stable, so the battery cover internal resistance measurement is accurate; The both positive and negative polarity probe to the pressure of battery cover less than 0.1N, very little to the internal resistance influence of lid own, measure accurately; Because cylinder drives, battery cover picks and places easily, and is easy to operate.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
