At the same time, they have very high requirements for surface cleanliness and shape integrity. The traditional copper gasket boxing method relies on manual operation, that is, the gaskets are picked up one by one by hand and placed into the packaging tube. Even if the operator wears gloves, it is difficult to avoid contaminants such as sweat stains and oil stains from adhering to the surface of the copper gasket. Moreover, for copper gaskets with a large inner diameter, this boxing method is prone to cause the copper gasket to bend and twist, resulting in product scrap. SUMMARY
