Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
For this manual internal resistance test device for the test to soft package lithium battery internal resistance, soft package lithium battery includes positive plate, cathode
Piece is separated between positive plate and negative electrode tab by diaphragm, but in the actual production process, diaphragm is it is possible that breakage etc.
Situation so causes positive plate and negative electrode tab that can contact conducting to form short circuit, therefore the soft package lithium battery thus produced is not
It is qualified.Soft package lithium battery is after manufacture it sometimes appear that bulge phenomenon, the reason is that when due to production between positive plate and negative electrode tab
Between each other there is certain interval not eliminate, that is, mutually compresses and suffer not over diaphragm between positive plate and negative electrode tab
, but the intermediate air layer for having also appeared certain interval, even when above-mentioned described diaphragm occur there are the situations such as breakage,
Due to the air layer with the presence of certain interval, positive plate and negative electrode tab do not turn on to form short circuit due to that will not contact,
It is unqualified that its just so can not be tested in test, that is to say, that will be existed practical substandard product when qualified products dispatch from the factory
Into market, then will have larger security risk in actual use.Therefore, it needs when testing by above situation
Qualification is tested whether after eliminating again.This manual internal resistance test device can be eliminated before testing to be deposited between positive plate and negative electrode tab
The air layer of certain interval prevent substandard product when qualified products enter market so that test accuracy rate is higher.
As shown in Figure 1, this manual internal resistance test device includes bottom plate 1, the first lower platen 9, the second lower platen 12 and positive and negative survey
Probe header 3,4, bottom plate 1 are equipped with battery positioning plate 2, the limit for having battery rest area 21 on battery positioning plate 2 and convexing to form
Position convex edge 22,21 size of battery rest area match with soft package lithium battery shape size.The height of positive and negative test probe 3,4 is high
Height in above-mentioned battery rest area 21 only need to be by one avris of lithium battery against limit convex edge when placing soft package lithium battery to be measured
22, have that side of positive and negative tab against positive and negative test probe 3,4, can fast and easy contraposition lithium battery is accurately placed to electricity
On pond rest area 21；After placing, the positive and negative tab of soft package lithium battery positive and negative electrode on piece is located at above-mentioned positive and negative test
The surface of probe 3,4.
Circuit conversion connector 5, the input terminal of circuit conversion connector 5 and positive and negative test probe 3,4 are fixedly provided on bottom plate 1
Connection, output end are connect with above-mentioned digital display multimeter 6, so that the connection of test circuit is formed, after circuit is connected, if digital display general-purpose
Resistance is shown on table 6 close to if zero, illustrating that short circuit phenomenon occurs for circuit, and positive plate in soft package lithium battery and negative is judged with this
Internal resistance is zero between pole piece, and short circuit occurs, then judges that the soft package lithium battery is unqualified；Conversely, if showing electricity on digital display multimeter 6
Resistance has certain numerical value, then illustrates there is certain internal resistance between positive plate and negative electrode tab, and there is no short circuits, then judgement should
Soft package lithium battery is qualified.
First lower platen 9 and the second lower platen 12 are located at above-mentioned battery rest area 21 and positive and negative test and pop one's head in 3,4
Surface is additionally provided with the first driving mechanism and the second driving mechanism on bottom plate 1.Wherein, the first driving mechanism includes that foot is stepped on out
The lower air cylinder bracket 7 close, being fixedly mounted on bottom plate 1 and the lower air cylinder 8 being connected on lower air cylinder bracket 7, under first
Pressing plate 9 is connected on the piston rod of lower air cylinder 8, and foot steps on switch and connect with lower air cylinder 8 and can control the work of lower air cylinder 8.
When needing to push, foot is stepped on foot and steps on switch, the work of lower air cylinder 8 drives the extruding of 9 downlink of the first lower platen soft by piston rod
Packet lithium battery compresses downwards soft package lithium battery, compresses positive plate and negative electrode tab and is close to, with eliminate positive plate and negative electrode tab it
Between gap, to eliminate bulge phenomenon.Further, lower air cylinder bracket 7 is gantry support, and the first lower platen 9 is insulation
Backing plate.Second driving mechanism includes the tested cylinder bracket 10 being fixedly mounted on above-mentioned bottom plate 1, is connected in tested cylinder bracket
Tested cylinder 11 and above-mentioned foot on 10 step on switch, and the second driving mechanism shares the same foot with the first driving mechanism and steps on out
It closes, the second lower platen 12 is connected on the piston rod of tested cylinder 11, and above-mentioned foot steps on switch and connect and can control with tested cylinder 11
Tested cylinder 11 processed works.When foot steps on foot and steps on switch, lower air cylinder 8 and tested cylinder 11 are worked at the same time, and the first lower platen 9
Reach designated position simultaneously with the second lower platen 12, i.e., the gap between elimination positive plate and negative electrode tab simultaneously, the second lower platen
12 are pressed on positive and negative tab the circuit company that positive and negative plate and digital display multimeter 6 are realized on positive and negative test probe 3,4 respectively
It is logical.One lithium battery of every test need to only step on a foot and step on switch and can be realized and eliminate having synchronized for bulge phenomenon and inner walkway
At testing efficiency is high, and overall structure is simple, easy to operate.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
