Inspection principle
The general process flow of pole piece coating is as follows: unwinding tension control-automatic deviation correction-coating-drying-automatic deviation correction tension control-rewinding; in the initial stage of drying, due to the thickness of the slurry itself, the slurry will There is a large humidity gradient from the inside of the slurry to the surface of the slurry.
Excessive surface evaporation will lead to significant shrinkage, resulting in excessive drying and excessive shrinkage, which will cause high stress inside the pole piece, causing the pole piece Wrinkles or bends; during the entire coating process, since the pole piece itself is very thin and has poor toughness, it is necessary to accurately control the advancing speed of the tension of the pole piece, but the control process will also cause various reasons. The tension and speed are not constant, so the pole piece is also prone to wrinkles or cracks.
Functions of system
Inspection result
The system adopts high-precision linear track slide table, high-precision rotary platform, high-precision fixture platform, high-reliability motor and control system to realize the automatic process of battery loading, testing and unloading.
It is mainly used to detect defects such as pits, bulges, and scratches on the appearance of lithium batteries. According to the system algorithm and user-defined industrial parameters, the detection results are output in real time, and the lithium batteries are automatically sorted into qualified and unqualified products through the automatic mechanism. Moreover, the system is compatible with the MES industrial system, which is convenient for real-time synchronous detection of statistical data.
Advantages of CCD vision
1)High detection accuracy and fast detection efficiency:CCD visual inspection equipment uses machine control according to the system, with small error and high detection rate.
2)Wide detection range to detect cosmetic defects and dimensional measurements:The multi-station inspection method can accurately measure the outline, specifications, appearance defects, product aspect ratio and other performance parameters of the product to be inspected at one time.
3)Improve product quality and error rates:Vision inspection equipment is based on system control, which can distinguish good products from bad products through automatic inspection technology, and then automatically place them in different parts.
4)Save labor costs and enable high repetitive work:CCD visual inspection can work stably for a long time, it is difficult for human eyes to observe the same object for a long time, and machine vision can perform measurement, analysis and recognition tasks for a long time. And it can continue to work, with low requirements for the natural environment of the application, in addition to saving product costs, it also greatly improves productivity.
5)Improve company competitiveness and employee safety factor:Non-contact detection, which does not cause any damage to observers and observers, improves the reliability of the system. Machine vision technology guarantees the ultimate human-machine interaction technology, which ensures a better and safer workplace.
