Description
Technical field
The utility model relates to a kind of lithium battery seal machine, relates in particular to a kind of based on the lithium battery negative pressure sealing machine under the subnormal ambient.
Background technology
Along with the development of twentieth century microelectric technique, production and the application of lithium battery have obtained fast development.The advantages such as voltage platform height, self-discharge rate are low, adaptable because lithium battery has, long service life, environmental protection, replacing lead-acid battery and nickel-cadmium cell are widely used in the fields such as electric automobile, electric bicycle, mobile phone, notebook computer, mine lamp, household electrical appliance in recent years.
At the lithium battery production field, exist for a long time a technical barrier: how lithium battery seals liquid injection port after injecting electrolyte always, two pole pieces of liquid injection port and battery are on the same sidewall of lithium battery, such as Fig. 1, the diameter of liquid injection port 20 only has 1.3mm, and the mode of sealing is that the steel ball with diameter 1.5mm is pressed on the hole of liquid injection port 1.3mm steadily, securely.
Because the diameter of steel ball and liquid injection port is too little, in the manufacturing enterprise of lithium battery, mostly adopt manual or semi-automatic mode to realize the sealing of lithium battery liquid injection port at present, consult domestic and international pertinent literature, sum up and get up to have following two kinds of general modes:
Manual type is manually put into lithium battery on the location-plate, and then the cylinder clamping lithium battery is clamped steel ball with tweezers and put to the lithium battery liquid injection port, utilize the good steel ball of the plane regulating orientation of tweezers after, utilize the drift of lithium battery top to move down steel ball pounded in the entrance.Adopt the shortcoming of manual type to be:
