Description
Technical field
The utility model relates to flexible packing lithium ion battery production equipment, specifically is a kind of lithium battery fluid injection and changes into and vacuumize integrated apparatus.
Background technology
In recent years, but lithium ion battery because have operating voltage height, energy density height, have extended cycle life, 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 crucial effects in lithium battery manufacturing process, it has determined 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 the formula of vacuumizing or gasbag-types by the mode of changing into, both are as follows to the environmental requirement of fluid injection and formation process, vacuumize formula: 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 insert when changing into, pull out the PP pipe, unavoidably make inside battery contact with extraneous, so the humiture that changes into the 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 to the influence of battery, and process is loaded down with trivial details, not only increases the manufacturing cost of electric core, and influences the quality of battery.
The utility model content
The purpose of this utility model is the weak point that overcomes 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, cut down the consumption of energy, overcome in fluid injection, the formation process ambient moisture simultaneously to the influence of battery, increase battery capacity, promote battery cycle life.
The technical solution of the utility model 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 the handle two ends have " Z " and " C " printed words respectively; 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, but the regulating cell fluid injection, battery is shelved and battery changes into and 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 the fluid injection of several batteries simultaneously and change into.
The beneficial effects of the utility model are: 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 the fluid injection of many batteries simultaneously and change into, simplified technology, less artificial consuming time; 4) change into than gasbag-type, reduced the aluminum plastic film consumption, it is more abundant that preliminary filling gas is discharged, and promotes battery performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In conjunction with Fig. 1, the utility model is described further.
Referring to Fig. 1, lithium battery fluid injection and change into and vacuumize integrated apparatus, constituted 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, the handle two ends have " Z " and " C " printed words respectively, 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 isolates simultaneously, 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 piston and close automatically, 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.
