Special-shaped angle ultrasonic welding seat structure

Abstract

The invention discloses a special-shaped angle ultrasonic welding seat structure. The special-shaped angle ultrasonic welding seat structure is characterized by comprising an upper connecting structure connected with a machine frame structure, an extension structure arranged at the lower part of the upper connecting structure and an embedded type ultrasonic welding structure connected with the lower part of the extension structure, wherein the upper connecting structure comprises an upper connecting block connected with the machine frame structure and a longitudinal adjusting block structure connected to the lower portion of the upper connecting block, and the embedded type ultrasonic welding structure comprises a welding connecting block, an embedded ultrasonic welding head set arranged in the welding connecting block, and a spacing adjusting structure arranged between the welding connecting block and the embedded ultrasonic welding head set. The special-shaped angle ultrasonic welding seat structure has the beneficial effects that the scientific and reasonable structure design that multiple transversely-arranged transverse arc-shaped through grooves and multiple longitudinally-arranged longitudinal arc-shaped through grooves are formed in a welding head body is adopted, so that the welding firmness of automobile plastic parts is guaranteed, the overflow phenomenon is not prone to occurrence, and the quality of welding is further ensured.

Description

technical field [0001] The invention relates to an ultrasonic welding seat structure with special-shaped angles, in particular. Background technique [0002] Ultrasonic welding is the use of high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form fusion between molecular layers. When the ultrasonic wave acts on the thermoplastic contact surface, tens of thousands of high-frequency vibrations per second will be generated. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Since the welding area is two The acoustic resistance at the interface of two welds is large, so local high temperature will be generated. And because of the poor thermal conductivity of the plastic, it cannot be dissipated in time for a while, and it gathers in the welding area, causing the conta...
