[0002] At present, in industrial manufacturing, welding technology is still widely used in the connection method of many products and equipment. The existing welding technology still requires a lot of manual operations. Simple workpieces can be directly welded. However, if it is a filtering product in the semiconductor industry, when the product is assembled in a multi-layer barrel structure, manual positioning is prone to inaccurate positioning, and inaccurate positioning will, to a certain extent, lead to problems such as increased scrap rate or low product pass rate. Because the multi-layer barrel structure needs to be equipped with filter cotton when it is used for purification, air impurities can be filtered by the filter cotton when passing through the annular channel of the multi-layer barrel structure. However, since the filter cotton is a standard consumable, when it needs to be replaced, the inaccurately positioned barrel structure will make it difficult for customers to replace and install it.
