Description

一种多通道阻差均衡及聚能快固一体机 技术领域
本发明涉及电池模组冷焊技术领域，特别是涉及一种多通道阻差均衡及聚能快固一体机。
技术背景
随着新能源汽车的发展，电池模组的使用越来越广泛。为了提升电池模组的蓄电量，电池模组中需要安装成百上千的电池共同工作。由于电池模组中的电池数量较多，可以考虑利用胶水冷焊的方式提升稳定性，比如利用导电胶进行电池负极与母排的连接或者电池侧面与外框架的连接，然后用紫外线照射固化，生产效率较高。
实际生产过程中，由于冷焊点较多，需要在电池模组上加工的点胶孔数量较多，给紫外线照射固化带来了困难，工作效率低，还容易导致紫外线的泄漏问题，影响生产的安全性。
另外，电池模组点胶后直接进行紫外线照射固化往往存在质量缺陷，由于部分电池负极与母排接触的压力不同，导致电池与母排的接触电阻差异较大，而导电胶固化后难以进行调整，导致产品存在安全隐患。因此，还需要在光固前对电池模组进行阻差检测和调整，而且现有技术中，并没有可以对电池模组中电池负极与母排接触压力进行调整的设备，只能单独进行电阻的检测、调整和光固，工作效率低，工序衔接性差。
