Ultrasonic Welding Automation


Ultrasonic plastic welding is to transmit high-frequency mechanical vibrations through the workpiece to the interface part to accelerate the movement of the molecules. The molecular friction is converted into heat to dissolve the plastic at the interface, so that the two weldments are truly integrated into one another by molecular coupling. Because this molecular motion is done in an instant, most of the ultrasonic plastic welding can be completed in 0.25 to 0.5 s. Ultrasonic plastic welding is suitable for plastic parts with small welding area, regular structure and thermoplasticity.

Plastic welding technology has been successfully used in automotive warranty bars, instrument panels and dashboards, brake display lights, direction indicators, automotive door panels and other engine-related parts manufacturing industries. In recent years, many of the traditional metal-used parts have also been replaced with plastics, such as intake pipes, instrument pointers, radiator reinforcement, fuel tanks, filters, and so on. Vibration friction welding is suitable for workpieces with large welding area and complicated structure, and there is no special requirement for plastic type.


As a traditional basic process and technology in manufacturing, the history of application in industry is not long, but its development is very rapid. The welding robot is an advanced welding equipment developed on the basis of industrial robots. It is an industrial robot engaged in welding (including cutting and spraying). It is mainly used in the field of industrial automation. It is widely used in the manufacture of automobiles and parts, motorcycles, engineering. Machinery and other industries have been widely used in the four major production processes of stamping, welding, painting and final assembly of automobile production. Among them, arc welding and spot welding are the most widely used.


Typical welding robot systems are available in the following forms: welding robot workstations, welding robot production lines, and welding special machines. The welding robot system is generally suitable for medium and small batch production. The weld seam of the welded workpiece can be short and many, and the shape is more complicated. The flexible welding line is especially suitable for the variety of products, and the number of each batch is very small. The welding special machine is suitable for products with large batch size and slow modification. It is also suitable for workpieces with small number of welds and long shape and regular shape. As for the type of automatic welding production, it depends on the actual situation of the enterprise.
