Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] As shown in the figure, the lithium battery electrolyte injection system with an automatic delivery mechanism in this embodiment includes a feed unit, an intermediate liquid injection unit and a discharge unit,

[0027] The intermediate liquid injection unit includes an intermediate belt conveyor 1 and several battery positioning molds 2 hinged on the intermediate belt conveyor. The specific hinged connection mode of the battery positioning molds is shown in the figure. The two ends of the positioning mold are provided with hinged shafts that rotate with the hinged seat, and the bottom surface of the battery positioning mold leans against the conveyor belt;

[0028] The middle liquid injection unit also includes a lifting plate 3 above the middle part of the middle belt conveyor and a lifting cylinder 4 vertically fixed on the frames on both side...

Abstract

The invention discloses a lithium battery electrolyte injection system with an automatic conveying mechanism, which includes a feeding unit, an intermediate liquid injection unit and a discharge unit, and the intermediate liquid injection unit includes an intermediate belt conveyor, a battery positioning mold, a lifting plate, Lifting cylinders, quantitative liquid injectors, etc.; the feeding unit and the discharging unit include belt conveyors, linear motors, beams, straight slide rails, positioning cylinders, positioning blocks, pick-up cylinders, corner cylinders and vacuum suction cups. Invented a lithium battery electrolyte injection system with an automatic delivery mechanism, which injects liquid into the lithium battery through a quantitative liquid injector. The amount of electrolyte released by the sub-injection cylinder from the quantitative cylinder is consistent, and is exactly equal to the standard liquid injection volume of the lithium battery, and the injection accuracy is high; and its feeding and discharging are automatically completed, and the feeding and discharging speed is fast ,high productivity.

Description

technical field [0001] The invention relates to battery production equipment, in particular to a battery electrolyte injection machine. Background technique [0002] When the lithium-ion battery is working normally, the negative terminal drawn from the negative current collector and the positive terminal drawn from the positive current collector form an electronic path with the external circuit, and the lithium ions in the electrolyte and the positive and negative active materials form an ion path, an electronic path and an ion path Form a circuit together to achieve the purpose of normal work. As the demand for lithium-ion batteries gradually increases, people have higher and higher performance requirements for them, especially for the cycle performance of the battery, and the liquid injection volume of the battery is an important parameter to ensure the battery cycle. Too little liquid injection will cause the cycle to decay too quickly, resulting in too fast decay of the...
