Summary of the invention
The invention discloses a kind of Soft Roll formula measure apparatus of thickness of lithium battery, not only solve that current test soft bag lithium ionic cell poor accuracy, consistance are poor, deficiency that narrow application range and contrast thereof have little significance aspect, there is the soft-package battery method of testing that accuracy is high, consistance is strong, applied widely, contrast meaning is strong, and the thickness testing soft-package battery is maximum gauge, compares and adopt the random thickness of milscale test to have larger modular design reference significance.
The present invention includes bottom base 1, top base 2, top base 2 is provided with silk guide frame 3 above, the below of silk guide frame 3 is provided with pricker 4, the side of silk guide frame 3 is provided with thicknessmeter 5, and the side of top base 2 is provided with control system 6, and top base 2 end face is provided with level meter 7, adopt adjustable pillar to make somebody a mere figurehead between top base 2 and bottom base 1, top base 2 is parallel with bottom base 1.
Described pricker 4 adopts following material mixture ratio to form: lithium metaaluminate 1 ~ 5%, iron 60 ~ 92%, carbon 1 ~ 20%, nickel 1 ~ 2%, manganese 1 ~ 2%, cupric oxide 3 ~ 5, mercury 1 ~ 2%.
Comprise barometer in control system, its air pressure size is 0.3 ~ 0.6mpa.
Bag counting note in control system, to record the quantity of test battery, quantity is from 1 ~ 9999.
In control system, the Soft Roll press time is 1 ~ 60S.
Being applicable to test soft-package battery gauge scope is 1 ~ 20mm.
Be applicable to test soft-package battery be of a size of, length × wide=1 ~ 200mm × 1 ~ 200mm.
Beneficial effect:
Due to aluminum plastic film thinner thickness, it is higher to the accuracy requirement of thickness, and adopt milscale to there are differences because of people owing to applying pressure, time, cause the consistance of test thickness poor, and adopt thicknessmeter test soft-package battery different pressures, different time can be set according to the actual (real) thickness of soft-package battery, and each maximum gauge can be recorded, improve its accuracy and consistance.
Be in horizontality because the employing of this patent of invention top base has level meter can adjust top base whereabouts compacting battery, reduce its thickness error, improve its data accuracy and reliability,
Because pricker 4 adopts above-mentioned material, when piercing through cell aluminum-plastic membrane, effect prevents short circuit, improves the security of operation.
The deficiency that the present invention not only solves that current test soft bag lithium ionic cell poor accuracy, consistance are poor, narrow application range and contrast thereof have little significance aspect, there is the soft-package battery method of testing that accuracy is high, consistance is strong, applied widely, contrast meaning is strong, and the thickness testing soft-package battery is maximum gauge, compares and adopt the random thickness of milscale test to have larger modular design reference significance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Symbol description in Fig. 1: bottom base 1, top base 2, silk guide frame 3, pricker 4, thicknessmeter 5, control system 6, level meter 7.
Embodiment
As shown in Figure 1, a kind of Soft Roll formula measure apparatus of thickness of lithium battery, bottom base 1, top base 2 are the present invention includes, top base 2 is provided with silk guide frame 3 above, and the below of silk guide frame 3 is provided with pricker 4, and the side of silk guide frame 3 is provided with thicknessmeter 5, the side of top base 2 is provided with control system 6, top base 2 end face is provided with level meter 7, and adopt adjustable pillar to make somebody a mere figurehead between top base 2 and bottom base 1, top base 2 is parallel with bottom base 1.
Described pricker 4 adopts following material mixture ratio to form: lithium metaaluminate 2.15%, iron 82.8%, carbon 6.9%, nickel 1.22%, manganese 1.48%, cupric oxide 4.2%, mercury 1.25%.
