Abstract
Lithium ion battery liquid injection of the present utility model and standing fixture, move forward and backward fixing lithium ion battery by air cylinder driven clamping side plate and squeeze out the air of inside lithium ion cell simultaneously, electrolyte is easier to penetrate into inside lithium ion cell and infiltrate pole piece, and impregnation process required time greatly reduces；Stand under vacuum conditions after lithium ion battery liquid injection, air can be prevented effectively from and enter battery, reduce note, liquid difficulty, shorten time of repose, significantly improve fluid injection and stand efficiency and product quality.
Description
Technical field
This utility model relates to a kind of lithium ion battery liquid injection and stands fixture, is applied to lithium ion battery manufacturing.
Background technology
Lithium ion battery needs inject electrolyte and infiltrate to pole piece in process of production, and tradition liquid injection process uses normal temperature and pressure fluid injection, and the gap of lithium ion battery electrolysis solution infiltration is the least, and electrolyte permeability is highly difficult；And inside pole piece, there is air so that electrolytic solution permeation enters inside lithium ion cell and infiltrates pole piece very slowly, the longest, and lithium-ion electric pool size the biggest fluid injection difficulty is the biggest, the longest；General employing vacuum liquid filling technology in prior art, during vacuum liquid filling, electrolysis side has air to enter, and easily because of pressure reduction generation electrolyte splash, and evacuation operation is loaded down with trivial details, with high costs；Regardless of whether use which kind of mode to lithium ion battery liquid injection, all needing to stand for a long time so that electrolyte fully permeates infiltration Battery Pole Core, the stability standing process directly affects lithium ion battery liquid injection effect.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of lithium ion battery liquid injection is provided and stands fixture, it is easy to electrolyte and injects lithium ion battery, air is avoided to enter inside lithium ion cell, reduce time of repose after fluid injection, promote electrolyte effect of impregnation, after improving product fluid injection and fluid injection, stand quality.
Lithium ion battery liquid injection of the present utility model and standing fixture, include casing, it is provided with some to clamping side plate for clamping lithium ion battery in casing, every pair of clamping side plate has side plate to be fixed on box house, another side plate is can be carried out, by air cylinder driven, the mobile side board that moves forward and backward, being provided with heater in every pair of clamping side plate, heater is by clamping side plate to lithium ion battery heat temperature raising, and heater is heating silica gel plate.
Lithium ion battery liquid injection of the present utility model and standing fixture, casing connects vacuum extractor, can stand under vacuum conditions after box sealing.
Lithium ion battery liquid injection of the present utility model and standing fixture, move forward and backward fixing lithium ion battery by air cylinder driven clamping side plate and squeeze out the air of inside lithium ion cell simultaneously, heater is by clamping side plate to lithium ion battery heat temperature raising, electrolyte is easier to penetrate into inside lithium ion cell and infiltrate pole piece, and impregnation process required time greatly reduces；Stand under vacuum conditions after lithium ion battery liquid injection, air can be prevented effectively from and enter battery, reduce note, liquid difficulty, shorten time of repose, significantly improve fluid injection and stand efficiency and product quality.
Accompanying drawing explanation

Fig. 2 is this utility model embodiment preferred version perspective view.
Detailed description of the invention
nullAs shown in the figure，A kind of lithium ion battery liquid injection and standing fixture，Include casing 1，It is provided with some to clamping side plate for clamping lithium ion battery 4 in casing 1，Every pair of clamping side plate has a fixed side 5 to be fixed on casing 1 inside，Another side plate is can be driven, by cylinder 2, the mobile side board 3 carrying out moving forward and backward，After being provided with heater 6 heating clamping in every pair of clamping side plate side plate reaching design temperature，Lithium ion battery 4 is inserted in every pair of clamping side plate，Cylinder 2 drives mobile side board 3 to move forward clamping lithium ion battery 4，And extrude eliminating lithium ion battery 4 inner air，Device for simultaneous heating 6 is conducted lithium ion battery 4 heat temperature raising by clamping side plate，During fluid injection, mobile side board 3 is in impaction state，After fluid injection completes，Cylinder 2 drives mobile side board 3 to be moved rearwards by unclamping，Suitably reduce lithium ion battery 4 pressure applied，It is beneficial to electrolyte and enters lithium ion battery 4 inside，Subsequently into standing operation；Standing operation to stand under vacuum conditions, after seal case 1, direct evacuation stands.
This utility model embodiment arranges case lid 7 and is packaged in formation sealing space above casing 1, and then evacuation stands, it is to avoid extraneous air enters battery；At high temperature, electrolyte viscosity and surface tension reduce so that electrolyte infiltration battery speed is accelerated；After standing completes, cylinder 2 drives mobile side board 3 to be moved rearwards by, and unclamps lithium ion battery 4, is then taken off by lithium ion battery 4, and fluid injection has stood；Lithium ion battery liquid injection of the present utility model and standing fixture, can be prevented effectively from air and enter battery, reduce fluid injection difficulty, shorten time of repose, significantly improves fluid injection and standing efficiency and product quality.
