There are many production processes for lithium batteries. How to accurately detect the internal defects and product quality of lithium batteries is of great significance to the efficient production of lithium batteries. The online visual inspection system can complete the surface defect detection of pole pieces, diaphragms and other materials, and "check each layer" for the production of raw materials for lithium batteries.

During the production of lithium battery pole pieces, the system can be deployed in multiple production links. First of all, the system can be installed on the coating machine as the first checkpoint to monitor the coating abnormality and dislocation online. Secondly, install the slitting machine to detect defects such as leakage of positive and negative materials, burrs, etc. Among them, "burrs" are difficult to detect. The company's self-developed ultra-long depth of field adaptive system can eliminate the influence of pole piece offset on detection and effectively ensure burrs. detection effect and accuracy. In addition, the system can also detect the slitting size, ensure the compliance of the slitting size, and link with the labeling system to kick waste in the winding or lamination section.

The separator is the key inner layer component of the lithium battery. The quality of the separator directly affects the capacity, cycle ability and safety performance of the lithium battery. In the detection of diaphragm defects, the "oil spot" detection tests the real strength of the system. The company has proposed targeted solutions to effectively solve this problem. Such achievements are beyond the reach of many manufacturers.

Copper foil and aluminum foil are also important raw materials for lithium batteries. The production line of copper foil and aluminum foil runs fast, and it is difficult to identify "pinhole" defects. The company's technology is advanced, and it can accurately identify "pinhole" defects on high-speed production lines with high detection accuracy. In addition to the above tests, the company's products can also be used in many aspects such as cell, module size, and appearance inspection.

The company can provide customers in the lithium battery industry with intelligent testing solutions covering the entire industry chain. Most of the mainstream wet-process diaphragm manufacturers in China have in-depth cooperation with us. It is believed that more and more customers will become Apogee's partners in the future.
