Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic welding, and in particular to an ultrasonic welding device and a continuous welding method. Background Art

[0002] Ultrasonic welding is an advanced assembly technology that uses ultrasonic vibration frequency to generate heat energy through friction between contact surfaces, so that two plastic parts are melted and fixed together at the welding interface. This technology converts low-frequency current into high-frequency electrical energy through an ultrasonic generator. This electrical energy is converted into mechanical vibration through a transducer and transmitted to the welding head. The welding head then transmits the vibration energy to the interface of the plastic parts to be welded, causing them to melt and connect. Ultrasonic welding has the advantages of energy saving and environmental protection, low cost, high efficiency, high welding strength, beautiful welds, and easy automated production. It is widely used in many fields such as automobile manufacturing, plastic electronics production, toy and stationery manufacturing, and medical supplies manufacturing.

[0003] After searching, the invention patent with Chinese patent number CN114589392A discloses an ultrasonic welding machine. Compared with the prior art, the invention patent with Chinese patent number CN114589392A places a mold frame for storing workpieces on an adjusting column, and then controls an electric telescopic rod, which controls the movement of a fastening frame. By pulling a fastening L-plate, a spring in a fastening groove is deformed by tensile force. After the fastening L-plate is against both sides of the mold frame, the fastening L-plate is loosened, and the spring is contracted to pull the fastening L-plate, so that the fastening L-plate clamps both sides of the mold frame. A limit block at one end of the fastening L-plate is located on the fastening groove to prevent the fastening L-plate from being separated from the fastening groove. Two electric telescopic rods are provided and symmetrically arranged, so that the two fastening frames clamp the other two sides of the mold frame. After the mold frame is fixed, the workpiece is placed on the mold frame, and then the ultrasonic welding mechanism is controlled to perform ultrasonic welding on the workpiece.

[0004] However, in actual use, it is not easy to continuously weld multiple welded parts at the same time. After welding a workpiece, the staff needs to re-place the materials for welding. The work efficiency of the welding process is low. At the same time, the welded parts are in a relatively fixed state during the welding process. When the ultrasonic welder acts on the welded parts, there may be gaps of different sizes between the contact surfaces of the two welded parts. During the welding process, the vibration generated by the ultrasonic welder is not easy to act evenly between the welded surfaces, resulting in different tightness of the welded surfaces. There may be a situation of cold welding somewhere. Therefore, an ultrasonic welding device and a continuous welding method are proposed. Summary of the invention
