A battery liquid injection vibrating device

Abstract

A battery liquid injection vibrating device includes a horizontally mounted bottom plate, two vertical plates are arranged above the bottom plate, and a fixing plate parallel to the bottom plate is arranged on the top of the vertical plate, a plurality of through holes are arranged on the fixing plate, guide columns are arranged in the through holes through linear bearing devices, the guide columns pass through the upper and lower ends of the whole fixing plate, a floating plate is supported on the top of the guide columns, a fixture is arranged on the upper surface of the floating plate, andan electric core injected with hot electrolyte is fixed in the fixture; a motor is fixed on the bottom plate between the two vertical plates through a motor mounting plate, an eccentric wheel is mounted on the output shaft of the motor, the outside of the eccentric wheel sleeves a swing rod, the other end of the swing rod is movably connected with a connecting rod, a through hole is arranged in the middle of the fixing plate, and the top surface of the connecting rod head passes through the through hole and is locked with the bottom surface of the floating plate. The invention solves the problems of too long injection time and low injection efficiency of the electric cell, increases the stability of the vibration device and avoids liquid leakage and the like.

Description

technical field [0001] The invention relates to the technical field of battery liquid injection devices, in particular to a battery liquid injection vibration device suitable for square aluminum case (steel case) EV batteries. Background technique [0002] In the battery injection production process, the battery cell is usually injected with a liquid injection device composed of a cup body and a cup cover. Since the battery cell absorbs the electrolyte for a long time and the efficiency of one-time injection is low, it is necessary to The battery cell is heated and vibrated to increase its absorption rate of the electrolyte; most of the cell vibration devices used in the prior art are simple in structure and easy to operate, but due to their unreasonable structure, it is easy to cause the cell to be fixed unstable. lead to leakage, etc. Contents of the invention [0003] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provid...
