Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ultrasonic welding machines, and more specifically, particularly relates to a wire clamping structure of an ultrasonic welding machine. Background Art
[0002] The principle of ultrasonic welding machine is that the generator generates 20KHz (or 15KHz) high-voltage and high-frequency signals, and converts the signals into high-frequency mechanical vibrations through the transducer system, which are applied to the plastic workpiece. The temperature transmitted to the interface is increased through the friction between the workpiece surface and the molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is melted quickly and then filled in the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, and the welding purpose is achieved. The ultrasonic ultra-high frequency vibration welding head generates friction heat at the joint surface of the two pieces of plastic under moderate pressure, and melts and joins instantly. The welding strength is comparable to that of the body. With suitable workpieces and reasonable interface design, watertightness and airtightness can be achieved, and the inconvenience caused by the use of auxiliary products can be eliminated, realizing efficient and clean welding.
[0003] At present, the clamping tools used by ultrasonic welding machines for welding wire materials are generally tightened with bolts. Other tools are needed for fixing, which is troublesome. There is no effective protection for the wire materials, which may cause unavoidable damage to the wire materials. When adjusting the alignment, the alignment efficiency will be reduced due to being too flexible. Most ultrasonic welding machine wire clamping structures can only perform straight-line welding, and cannot be used for some welding that requires bending. Utility Model Content
