Description
Technical field
The present invention relates to flexible packing lithium ion battery production equipment, specifically be a kind of lithium battery fluid injection and change into and vacuumize integrated apparatus.
Background technology
In recent years, but lithium ion battery since have operating voltage height, energy density high, have extended cycle life, the advantages such as memory-less effect, non-environmental-pollution large current density, development obtains advancing by leaps and bounds in fields such as portable type electronic product, electronic toy, electric vehicle, large-sized power power supply and energy storage.
Fluid injection and chemical synthesis technology play vital effect in lithium battery manufacturing process, it has determined the various performances such as the film forming situation of battery and cycle life.In the electric enterprise of existing lithium, the fluid injection of battery and to change into nearly all be that operation break-down carries out, because electrolyte and water easily react, so moisture control has become the most important thing, therefore each man of lithium power plant is relatively harsher to environmental requirement between battery car, battery is divided into two kinds of vacuum-pumping type or gasbag-types by formation regime, both are as follows to the environmental requirement of fluid injection and formation process, vacuum-pumping type: adopt the fluid injection of PP pipe, generally be selected in 20 ± 5 ℃ of temperature, carry out in ℃ drying shed of dew point≤-30, need to insert when changing into, pull out PP pipe, inevitable so that inside battery contacts with the external world, so the humiture of formation workshop is also had certain requirement, be 15 ℃～35 ℃ of ambient temperatures, humidity≤40%; Gasbag-type: adopt uncovered fluid injection, stricter to the fluid injection environmental requirement, require 20 ± 5 ℃ of drying shed temperature, dew point≤-40 ℃, in said method, no matter how operating process is controlled, also can't avoid moisture on the impact of battery, and process is loaded down with trivial details, not only increases the manufacturing cost of battery core, and affects the quality of battery.
Summary of the invention
The objective of the invention is to overcome the weak point in the existing lithium battery making, a kind of simple in structure, easy to operate lithium battery fluid injection is provided and changes into and vacuumize integrated apparatus, adopt this device can simplify working process, reduce energy consumption, overcome simultaneously in fluid injection, the formation process ambient moisture to the impact of battery, increase battery capacity, promote battery cycle life.
Technical scheme of the present invention is: lithium battery fluid injection and change into and vacuumize integrated apparatus, its improvements are to be provided with double rows of pipelines and two piston of opening in this device, described double rows of pipelines is independently fluid injection pipeline and vacuum-pumping pipeline, two pistons of opening have three ports, 1st, 2 ports are isolated mutually, are connected with vacuum-pumping pipeline with liquid injection pipe respectively, and the 3rd port alternately is communicated with the 1st, 2 ports respectively, perhaps isolate simultaneously with the 1st, 2 ports, the 3rd port links to each other with the battery valve port.
Further scheme is: described two sides of opening piston are provided with the in-line handle, and there are respectively " Z " and " C " printed words at the handle two ends; Opening piston for described pair has 4～8, is connected in parallel on the double rows of pipelines; Be provided with in this device with two and open the program control part that piston links to each other.
Be provided with in this device with two and open the program control part that piston links to each other, described two pistons of opening can carry out manually and automatically regulating, and by this piston, the fluid injection of adjustable pond, battery are shelved and battery changes into and the operation such as vacuumizes.Described two opening is provided with probe in the piston, probe links to each other with program control part, by the accuracy of program control assurance injecting electrolytic solution amount.Described two piston of opening is 4-8, is connected in side by side on double-row type fluid injection and the vacuum-pumping pipeline by conduit, and this device can carry out simultaneously the fluid injection of several batteries and change into.
The invention has the beneficial effects as follows: 1) adopt totally enclosed fluid injection and change into to vacuumize integrated apparatus, effectively shield outside moisture to the adverse effect of battery, increase battery capacity, improve battery cycle life; 2) reduce technology for manufacturing electric core to the requirement of workshop condition humidity, reduce energy consumption; 3) with fluid injection and change into to vacuumize and be integrated, and carry out simultaneously the fluid injection of many batteries and change into, simplified technique, less artificial consuming time; 4) change into than gasbag-type, reduced the aluminum plastic film consumption, it is more abundant that pre-inflatable body is discharged, and promotes battery performance.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
By reference to the accompanying drawings, the present invention will be further described.
Referring to accompanying drawing, lithium battery fluid injection and change into and vacuumize integrated apparatus, consisted of by the fluid injection pipeline A in the double-row type pipeline and vacuum-pumping pipeline B and two piston 6, conduit 5 and program control part opened, A pipe left side 1 links to each other with fluid reservoir, B pipe left side 2 links to each other with vacuum pump, when changing into battery is carried out vacuum pumping, B pipe right side 3 links to each other with vacuum gauge, carries out vacuum and shows.Two sides of opening piston 6 have in-line handle 4, there are respectively " Z " and " C " printed words at the handle two ends, two pistons of opening have three ports, wherein 6-1 port and 6-2 port are isolated, be connected with A, B pipe respectively, the 6-3 port alternately is communicated with 6-1 and 6-2 port respectively or simultaneously isolation, and the 6-3 port is used with the battery valve port and linked to each other.Concrete operations are as follows during work: the conduit 5 that battery that at first will fluid injection installs therewith links to each other, this device can connect 4 batteries, during battery liquid-filling, control the control panel of program control part, begin to carry out fluid injection, this moment, two " Z " that open piston handle 4 held up, when electrolyte reaches the fluid injection requirement, two pistons of opening are closed, and namely handle is in level, carry out the process of shelving after the fluid injection, when battery changes into, twoly open piston handles 4 " C " ends up, by the technical papers requirement, by program control vacuum degree value and pumpdown time be set, after changing into end, vacuum pumping stops automatically, and this moment is two opens the piston autoshutdown, and handle is in level.
Electrolyte and extraneous contacting have been avoided in the use of this device, have reduced the negative effect of moisture to battery, adopt to vacuumize simultaneously to change into, thoroughly get rid of internal gas, eliminate positive and negative pole gap, the both positive and negative polarity active material is brought into play more fully, thus the useful life of having improved battery.
