Automatic riveting machine to the surface of the plate without any requirements, the connection point of the plate surface of the original coating, paint layer is not damaged. High degree of automation in connection process, single or multi-point simultaneous connection, non-destructive strength detection and automatic monitoring of the whole process, high production efficiency. The jointing technology without willow nail is a new connecting method which gradually replaces the traditional backward connecting technology. Because up to now the connection method which uses has the economical and the technical insufficiency. We only take spot welding as an example, its equipment is expensive, the connection cost is high, it is difficult to connect multi-layer plates and coated plates or aluminum, copper and stainless steel plates, but it is impossible to connect spray-painted plates, plates of different materials, plates with excessive thickness difference and plates with interlayer in the middle. At the same time, the spot welding connection will destroy the plating layer on the surface of the plate and produce thermal deformation. And all the unreliable factors in the process of connection processing can not be detected automatically without damage. In addition, the use of traditional methods of connection, single-piece connection cost is too high, such as riveting or thread connection method, the preparation of the corresponding transportation and spare parts costs, will cause high costs.
