Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding, in particular to a terminal ultrasonic metal welding machine. Background Art

[0002] Ultrasonic metal welding machines for terminals utilize high-frequency ultrasonic vibration waves transmitted to the surface of metal terminals. Under pressure, these waves cause the metal terminals to rub against each other, forming a molecular bond. Advantages of ultrasonic metal welding for terminals include high speed, energy efficiency, high bond strength, excellent conductivity, spark-free operation, and near-cold-processing, making them suitable for mass production in factories.

[0004] During the welding process, the existing ultrasonic terminal welding machine needs to align the connecting wire and place it directly under the welding head, and requires the staff to press continuously to ensure that the position does not shift. The operator must maintain a high degree of attention and stability to ensure the accurate position of the connecting wire to avoid poor welding or product damage, which increases the labor intensity and mental stress of the operator. Therefore, it is necessary to provide a welding machine that does not require the operator to position the connecting wire in the welding area. Utility Model Content

There is no need for the operator to manually align. The operator only needs to simply place the connecting wire, which simplifies the operating steps and reduces the labor intensity of the operator.

[0020] 2. Based on the first beneficial effect, by setting up the limit assembly, before welding, the operator first places the metal plate on the upper surface of the placement plate.
