Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding machines, in particular to an ultrasonic welding head which is convenient to disassemble for an ultrasonic welding machine. Background Art

[0002] Ultrasonic welding transmits ultrasonic energy to the welding area through the upper weldment. Since the welding area, i.e. the interface between the two welds, has a large acoustic resistance, local high temperature will be generated. Due to the poor thermal conductivity of plastic, it cannot be dissipated in time and gathers in the welding area, causing the contact surfaces of the two plastics to melt rapidly. After a certain pressure is applied, they are fused into one. When the ultrasonic wave stops working, the pressure is continued for a certain period of time to allow it to solidify and form. In this way, a strong molecular chain is formed to achieve the purpose of welding. The welding strength can be close to the strength of the raw material itself.

[0003] For example, an ultrasonic plastic welding machine with automatic welding head positioning provided by authorization number CN219544055U fixes the mold on the welding platform, starts the linear motor to drive the ultrasonic transducer and the welding head to be longitudinally aligned with the welding mold through the connecting plate, slider, slide groove, rotating shaft, fixed block, connecting rod, fixing ring and cylinder, and starts the servo motor to drive the ultrasonic transducer and the welding head to rotate and be horizontally aligned with the welding mold through the worm, turbine, rotating shaft, fixed block, connecting rod, fixing ring and cylinder; the goal of automatically aligning the welding head and the mold after replacing the welding mold in the ultrasonic plastic welding machine is achieved, and the problem of difficulty in aligning the mold with the welding head during installation due to the different shapes of the welding molds, which affects the welding effect, is avoided. The machine is very convenient to use.
