[0002] In electrical switching components, contacts and contact blades are common structural parts. The contacts and contact blades are connected by riveting. When connecting, the contacts are first assembled in the prefabricated holes of the contact blades, and then the contacts are fixed to the contact blades by riveting. The characteristics of this type of parts are extremely wide range of uses and a large number of parts, while the size of the contacts is very small. For a long time, the assembly work between the contacts and contact blades has been completed by a working mechanism combined with a large amount of manual labor.

[0003] The commonly used assembly method is to use an existing press and assist with mold feeding. During operation, the positioning and alignment of the prefabricated holes on the contacts and contact pieces is a major difficulty. Existing positioning methods usually include two: the first is manual assisted positioning. Manual operation not only has extremely low productivity, but also has the need for manual operations at all times during press operation, which can easily cause personal injury and is very unsafe; the second is to use an intelligent system robot to accurately position and transport the contacts and contact pieces. This method has high equipment costs and requires high equipment precision. Summary of the Invention
