The invention discloses a device for exhausting of a flexible lithium battery formation. A driving mechanism drives a sliding seat to slide along guide rails; an overturning mechanism or a lifting mechanism drives a pricking exhaust mechanism to turn or vertically move to be clamped on two sides of the flexible lithium battery; the pricking exhaust mechanism comprises a mounting seat, a first mounting arm, a second mounting arm, a power mechanism for driving the first mounting arm and the second mounting arm to move toward the same direction or opposite directions, a pricking needle arranged on the inner side of the free end of the first mounting arm, a needle guard arranged on the inner side of the free end of the second mounting arm and a second elastic sucker; the pricking needle is positioned in a die cavity of the first elastic sucker; the needle guard is positioned in a die cavity of the second elastic sucker; the first mounting arm and / or the second mounting arm is provided withan exhaust hole connected with a negative pressure system pipeline; when the first mounting arm and the second mounting arm are clamped on two sides of the battery, the power mechanism pushes the first mounting arm and the second mounting arm to move toward the opposite directions; the pricking needle and the needle guard are matched to prick an air hole on a battery bag; in addition, the first elastic sucker and the second elastic sucker are adsorbed to two sides of the battery; after the negative pressure system exhausts gas in the battery, a sealing mechanism seals the air hole.
Description
technical field [0001] The invention relates to the field of battery formation machinery, in particular to a gas extraction device for the formation of soft-pack lithium batteries. Background technique [0002] The soft pack lithium battery is to put the electrolyte into the packaging bag and seal it; after sealing, the battery needs to be formed. During the formation process of the battery, a large amount of gas will be generated. In order not to affect the formation of the battery, it is necessary to enlarge the storage space of the packaging bag to form an air bag area. The harmful exhaust gas generated by the formation is collected in the air bag area. After the formation is completed, Then cut the redundant part of the packaging bag and seal the packaging bag. Although this operation can avoid the tail gas generated by the formation from affecting the formation, it will cause waste of packaging raw materials, and the raw material cost of the packaging bag Higher, thus ...
