Step 31, sealing sample is cut along the axis of the oral area of cylindrical lithium ion battery；
Step 32, the oral area section cut out is polished until all battery oral area sections display.
Among one embodiment：In the step 3：Sample after sealing is splitted on milling machine or grinding machine, and to sample
Face is polished with sanding apparatus, until the section of battery oral area clearly shows.
Among one embodiment：In the step 4, the size that detection oral area section is shown is observed on video detection instrument, then
According to Size calculation go out sealing ring by compression ratio.
Among one embodiment：The pattern-making material selects rapid-result steel clay.
Compared with background technology, it has the following advantages that the technical program：
Oral area sealing is in pattern-making material (such as rapid-result steel clay) and forms sealing sample, cuts sealing sample to show mouth
Portion's section, the size that shows of observation detection oral area section, sealing ring is gone out by compression ratio according to Size calculation, then being capable of quick standard
Really obtain by compression ratio calculate needed for size, such as sealing ring thickness, then sequentially the acquisition Size calculation is by compression ratio, then subsequently
Can be according to the feasibility that sealing process is judged by compression ratio, detection is quick, accurate, cost is low.
Along the oral area of the lower battery of the axis cutting of vertical cylinder lithium ion battery, along the axle of the oral area of cylindrical lithium ion battery
Wire cutting sealing sample, sealing sample is cut along the axis of the oral area of cylindrical lithium ion battery；The oral area section that polishing is cut out
Until all battery oral area sections display, the dimensional accuracy detected is higher.
Closure part size can be more accurately detected using video detection instrument, detection error is improved, under the influence of avoiding
The compression ratio of one step calculates.
Embodiment
A kind of cylindrical lithium ion battery seals slice test detection method, it is therefore an objective to based on evaluation cylindrical lithium ion battery envelope
Whether mouth technique is reasonable and progress, including：
Step 1, the oral area of lower cylindrical lithium ion battery is cut, the oral area comprises at least the top of side wall；
Step 2, the oral area cut out using rapid-result steel clay parcel, make oral area sealing in rapid-result steel clay and form solid
Approved sample product；The rapid-result steel clay can to the metal material such as steel, iron, aluminium product carry out rapid link with repairing, using it is preceding be clay
Shape, do not drip, do not trickle in use, be nontoxic, be tasteless, be pollution-free, bonding soon, after solidification, intensity is high, hardness is good, temperature tolerance is strong,
Resistant to chemical etching, non-volatile, indeformable, adhesive effect is prolonged, and carrying operation is very convenient；Rapid-result steel clay such as U.S. is general applies for this
