Description

technical field [0001] The invention belongs to the technical field of lithium battery production, and in particular relates to an automatic weighing and sorting device for lithium battery pole pieces. Background technique [0002] The consistency of battery pole pieces means that the weight, shape and size of a group of battery pole pieces are located in a specific range, which can be divided into several intervals according to the requirements of the manufacturer; in addition, the consistency also includes the pole piece coating. cloth thickness etc. In the production process of lithium batteries, the consistency of the battery pole pieces directly affects the battery life, but due to the existing manufacturing errors, the battery pole pieces often have different weights. Therefore, in the production process, the battery pole pieces are generally classified according to weight. After weighing the weight, remove the overweight and ultra-light unqualified pole pieces, and d...

Problems solved by technology

[0003] At present, the process of weighing and sorting lithium battery pole pieces is usually manual operation, that is, manually weighing the pole pieces on an electronic scale and then classifying them. Emotion, physical strength, and behavioral state are very important, and are easily disturbed by human factors. Therefore, there are problems such as slow speed, high sorting error rate, low labor efficiency and high labor intensity in manual weighing and sorting of pole pieces.

[0004] The Chinese patent with the patent number ZL201010202222.3 discloses a method and a classification system for classifying battery pole pieces. The disadvantage of this method is that the method uses a manipulator to pick up the pole piece and directly put the pole piece on the electronic scale. In the process of falling chips onto the electronic scale, it will affect the electronic scale and affect the accuracy of weighing, and the classification system is complicated and the sorting efficiency is not high

The Chinese patent with application number 201010165935.7 discloses a pole piece weighing machine. Its shortcoming is that the pole piece weighing machine does not have a pole piece continuous feeding mechanism, which cannot ensure that the height and position of the pole piece are consistent when grabbing the pole piece. The device has a large sorting error rate
