Abstract
The invention is concerned with the assemble flow for the column lithium ion cell especially the infusing assembling flow, includes the following steps: sets the column lithium ion cell into the first infusing area; vacuumizes the cell and processes the first infuse; processes compression to the cell; vacuumizes the cell and compresses; sets the column lithium ion cell into the second infusing area; processes vacuumize for the infusing cell; compresses the cell; processes vcuumize, compress to the cell at the same working position; expels the cell.
Description
Technical field
This invention relates to the assemble flow of cylindrical lithium ion battery, relates in particular to the assemble flow of fluid injection link.
Background technology
Existing cylindrical lithium ion battery is in the enterprising luggage timing of automatic production line, the assemble flow of fluid injection operation is as shown in Figure 1: vacuumize → fluid injection → pressurize → vacuumize pressurize → leave standstill → secondary fluid injection district → battery discharges, whole operations in secondary fluid injection district all are in closed condition.Its device layout figure as shown in Figure 1, whole fluid injection link assembly line comprises three districts, the district is left standstill in a fluid injection district, secondary fluid injection district.
Leave standstill operation in theory and played effect after opening before being, the battery after the once fluid injection is fully absorbed electric liquid, and then enter next procedure by secondary fluid injection district.But actual conditions are really not so, and are at first respond well for indivedual fluid injections, the size battery that the fluid injection qualification rate is high, and before after fluid injection, leaving standstill, the basic noresidue supernatant liquid of battery surface; And bad for the fluid injection effect, the battery to the bad model of electric liquid absorption also has unabsorbed electric liquid to remain in battery surface after leaving standstill, and pollutes battery and equipment, can't guarantee the qualification rate of fluid injection.Also can further influence the anodal Laser Welding of back and the qualification rate of sealing process, not play due effect so leave standstill.Secondly, time of repose has accounted for 70% of fluid injection operation, greatly reduces production efficiency, and battery is exposed under the air for a long time simultaneously, may have impurity and moisture enters battery, and this security performance to battery is brought very big influence.Therefore we redesign liquid injection process on the basis of existing equipment.
Summary of the invention
The present invention is the new improvement of a technological process, and it mainly is the operation that leaves standstill after the consideration cancellation fluid injection, and the fluid injection operation is optimized again, makes every effort to enhance productivity and improve battery quality.
The present invention adopts following technical scheme.
A kind of method for injecting cylindrical lithium-ion battery, carry out the following step successively:
(1) cylindrical lithium ion battery is inserted one time the fluid injection district;
(2), implement fluid injection for the first time to battery vacuum-pumping;
(3) battery is pressurizeed;
(4) to pressurization again behind the battery vacuum-pumping;
(5) cylindrical lithium ion battery is inserted secondary fluid injection district;
(6) intercell is vacuumized once more.
(7) battery is pressurizeed;
(8) at same station battery is vacuumized, pressurizes;
(9) battery is discharged.
The present invention has cancelled the operation that leaves standstill that takies whole fluid injection installation time 70%, and the fluid injection operation has been optimized again by improving the fluid injection assemble flow, has saved installation time, has improved production efficiency greatly, and battery quality and fail safe also increase.Simultaneously, the fluid injection assemble flow need not that fluid injection is set again and leaves standstill the district after improving, and has improved the factory building utilance.
Description of drawings
Fluid injection link assemble flow and device layout figure before Fig. 1 liquid injection process improves;
Fluid injection link assemble flow and device layout figure after Fig. 2 liquid injection process improves.
Embodiment
We test the battery of complete series, at first the fluid injection in secondary fluid injection district is closed, but the vacuum in secondary fluid injection district, pressurization are still open, battery after such fluid injection just can well absorb in secondary fluid injection district, compared tangible lifting through a large amount of fluid injection qualification rates that experiment showed, with original technology; Secondly we progressively shorten time of repose, and the fluid injection qualification rate does not significantly decrease, and this is because not have through the battery that leaves standstill in secondary fluid injection district by vacuumizing and pressurizeing and realize absorption; We adjust the fluid injection parameter of equipment again at last, optimized and vacuumized pressing time, partly given vacuumizing, pressurizeing of secondary fluid injection district pressing time with all concentrating on vacuumizing of a fluid injection district in the past, so not only overall vacuumizing obtained prolongation pressing time, and but shorten to some extent the running time of unit cells.Owing to cancelled the process of leaving standstill, saved installation time simultaneously, average per tour can reduce the stand-by period about 1 hour, makes output also increase.
Be through the whole fluid injection process operations flow process after improving below, referring to Fig. 2:
Fluid injection district vacuumizes → and the fluid injection → pressurization of pressurizeing → vacuumize → secondary fluid injection district vacuumizes → pressurizes → vacuumize, pressurize → and battery discharges.In each pressurization steps, add and be pressed between the 0.3-0.4MPa.
Be suitable for production with the cylindrical lithium ion battery of complete series through the liquid injection process of redesign.
At new liquid injection process, this renewal also again experiment formulated the fluid injection parameter that a cover is fit to this flow process, as following table:
