Description
技术领域technical field
本实用新型属于锂电池生产技术领域，具体涉及一种锂电池极片自动称重分选装置。The utility model belongs to the technical field of lithium battery production, in particular to an automatic weighing and sorting device for lithium battery pole pieces.
背景技术Background technique
电池极片的一致性是指一组电池极片其重量大小和形状尺寸大小位于一个特定区间内，可根据厂家要求将重量大小和形状尺寸大小划分为若干区间；另外一致性也包括极片涂布的厚度等等。在锂电池生产过程中，电池极片的一致性直接影响电池寿命，但是由于存在的制造误差，电池极片往往重量不同，因此在生产过程中，一般要对电池极片按重量进行分档，称出重量后剔除超重和超轻的不合格极片，同时把合格的极片按不同重量分成若干挡来分别收集。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 divide the qualified pole pieces into several blocks according to different weights to collect them separately.
目前锂电池极片称重分选的这道工序通常是采用人工作业，即用人工的方式将极片在电子称上称量再分档，称重和分选极片的质量与人的情绪、体力、行为状态关系重大，容易受人为的因素干扰，因此人工称重分选极片存在着速度慢、分选差错率较大、劳动效率低下和劳动强度大等问题。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 status are of great importance and are easily disturbed by human factors. Therefore, manual weighing and sorting of pole pieces has problems such as slow speed, high sorting error rate, low labor efficiency and high labor intensity.
专利号为ZL201010202222.3的中国专利公开了一种对电池极片进行分类的方法及分类系统，其不足之处在于该方法利用机械手来吸取极片并直接将极片放在电子称上，极片下落到电子称上过程中，会对电子称造成影响，影响称重的准确性，且该分类系统装置复杂，分选效率不高。申请号为201010165935.7的中国专利公开了一种极片称重机，其不足之处在于该极片称重机没有极片连续进料机构，不能保证抓取极片时极片的高度位置一致，导致该装置分选差错率较大。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. During the process of falling the chips onto the electronic scale, it will affect the electronic scale and affect the accuracy of weighing. Moreover, the sorting 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. Cause the sorting error rate of this device is bigger.
