The vacuum heat-seal liquid injection machine comprises a main push cylinder, a flange base, a lifting seal pot, a telescopic corrugated pipe, a guide pillar, a linear bearing, a lifting seal pot seat plate, a heat-seal seat, a chute seat, a wedged sliding heat melter, a stand, a vacuum pump, and the like, wherein the operation processes of liquid injection and sealed encapsulation are synchronously finished in a vacuum state. Compared with the traditional drying-room liquid injection mode, the vacuum heat-seal liquid injection machine has the advantages of saving energy consumption of a dehumidifier consuming enormous energy and reducing moisture intervene by reducing the liquid injection process, thereby improving the quality of a lithium ion battery.
Description
Technical field
The present invention relates to a kind of lithium ion cell injection fluid-tight packing technique, particularly vacuum heat-sealing fluid injection machine.
Background technology
Existing lithium ion battery fluid injection need be accomplished at the very low drying shed of moisture, the design standard relative humidity 5% that has, and what have requires relative humidity 1%; Even lower requirement; Ultralow wet environmental requirement need consume a large amount of dehumidifying energy consumptions, and even so low humidity standard is accomplished because fluid injection and encapsulation are divided into two technology positions; 2 technologies is that the time of staying is different in size; Airborne micro-moisture is got involved through fluid injection in the electrolyte of lithium ion battery, and is still inevitable, and the electrolyte water content of lithium ion battery what all have crucial influence with the performance and even the fail safe of lithium ion battery.
Summary of the invention
The present invention will provide a kind of purpose that electrolyte is accomplished sealed package simultaneously of in vacuum tank, injecting, and vacuum tank inter-sync fluid injection encapsulation reaches the purpose of the intervention of avoiding moisture.
Realize that technical scheme of the present invention is; Vacuum tank is made up of a up-down hermetically sealed can and heat-sealing seat, and the up-down hermetically sealed can is by promoting mainly the cylinder operation closure or openness; The heat-sealing seat is provided with fluid injection adapter and electric heating heat melting device, and in vacuum tank, operates the heat melting device functional entity.
Specify; The top cylinder Connection Block connection of push cylinder and up-down hermetically sealed can, the linear bearing that is sleeved on the guide pillar is connected with up-down hermetically sealed can seat board, and push cylinder is done when carrying out journey; Within the travel range of guide pillar; The up-down hermetically sealed can is descending, closely contacts with the heat-sealing seat, constitutes vacuum tank.When push cylinder was done return-stroke, the up-down hermetically sealed can was up, left the heat-sealing seat, located opening, when locating opening, can arrange that the aluminum-plastic composite membrane containment structure battery that needs the encapsulation fluid injection is to the fluid injection station.
Vacuum connection tube is connected with heat-sealing seat board threading, when the open vacuum pump; Bleed to the up-down hermetically sealed can through the inflation electromagnetically operated valve; Find time the air in the up-down hermetically sealed can; Fluid injection when air is evacuated, the inflation electromagnetically operated valve automatically shuts down the atmosphere path when vacuum pump is shut down, can keep vacuum state in the container.
Clamping cylinder is installed in the up-down hermetically sealed can, and the stroke end of clamping cylinder is connected with reduction pulling seat flange, and reduction pulling seat flange is connected with the upper flange of bellows; The lower flange of bellows is connected with up-down hermetically sealed can seat board; Hypotenuse compresses card in installing in the bellows chamber, and interior hypotenuse compresses to be stuck in the bellows chamber and is connected with reduction pulling seat flange, when clamping cylinder is carried out journey work; Bellows is compressed, and interior hypotenuse compresses card and is urged descending.When interior hypotenuse compresses card and does downward movement; Wedge-type slip heat melting device is stuck and down is shifted, and the track of its motion is the interior to angle hypotenuse wedge groove of sliding chute seat, because sliding chute seat is interior to the guide effect of angle hypotenuse wedge groove; Make wedge-type slip heat melting device, do downward movement and do simultaneously in opposite directions and to move; Form the function that clamps, being seated in two aluminum-plastic composite membrane containment structure battery of installing in opposite directions between the wedge-type slip heat melting device in advance will be clamped, in the wedge-type slip heat melting device electrothermal tube is installed; Electrothermal tube wedge-type slip heat melting device under "on" position is heated, and the aluminum-plastic composite membrane containment structure battery that is clamped by wedge-type slip heat melting device will be sealed by hot melt.
Install in opposite directions before wedge-type slip heat melting device do not clamp aluminum-plastic composite membrane containment structure battery as yet at two; Take over to aluminum-plastic composite membrane containment structure battery notes electrolyte through fluid injection; Annotate electrolyte hot melt sealing more afterwards, electrolyte has just been packed in aluminum-plastic composite membrane containment structure battery at vacuum state.
The power supply of the heating electrothermal tube of the wedge-type of in vacuum tank, working slip heat melting device connects power supply by insulating terminal, and insulating terminal passes and seals the seat board installation, and such structure had both guaranteed vacuum in the hermetically sealed can, has reached power supply again and has inserted the requirement of insulating.
Positive effect of the present invention: with existing relative humidity 5%; Relative humidity 1% drying shed fluid injection mode has been saved the dehumidifier power consumption of huge power consumption; Water content in the vacuum tank is lower than existing relative humidity 5% significantly; Relative humidity 1% drying shed, thus the quality that moisture is got involved the raising lithium ion battery reduced through reducing liquid injection process.
