Description

Electric core mechanical rubbing equipment

Technical Field

The utility model relates to the technical field of battery processing, in particular to a mechanical cell flattening device.

Background

The battery cell is used as the most important component of the battery, and the battery cell can be assembled to form the battery after being sequentially subjected to the working procedures of mechanical/ultrasonic flattening, encapsulation, shell entering, current collecting disc welding and the like. Before the battery cell is subjected to rubbing treatment, the end part of the battery cell is uneven, flanging and more burrs can possibly occur, and certain degree of external deflection exists on concentricity relative to the battery cell body. In order to facilitate the subsequent welding of the current collecting disc at the end part of the battery core, the end part of the battery core needs to be flattened so as to ensure the welding quality of the current collecting disc.

Currently, oppositely arranged rubbing mechanisms are generally arranged at two sides of a battery cell conveying line so as to mechanically rub horizontally arranged battery cells conveyed by the battery cell conveying line. In the process of rubbing two ends of the battery core, the rubbing mechanisms at two sides of the battery core are required to be centered so as to ensure the rubbing quality. However, in practical application, since the rubbing mechanisms on two sides of the battery cell are mounted on the respective supporting seats, a certain mounting error exists between the two supporting seats, so that centering adjustment of the rubbing mechanisms on two sides of the battery cell is difficult to achieve.

Meanwhile, any one of the two rubbing mechanisms fails, and when maintenance is needed, the rubbing mechanisms on two sides of the battery cell are required to be detached from respective supporting seats, and when the rubbing mechanisms after maintenance are installed, centering adjustment is needed, so that the operation difficulty is high, and time and labor are wasted.
