Description

Technical Field

[0001] The utility model belongs to the technical field of cell welding, and particularly relates to an ultrasonic welding mechanism with an inverted welding method. Background Art

[0002] The final welding of the cell tab refers to the process in battery manufacturing where the electrode sheet and the tab are tightly connected through welding to ensure smooth conduction of the current inside the battery, reduce resistance loss, and thereby improve the performance and service life of the battery. Currently, the final welding of the cell tab can be carried out using an ultrasonic welding machine. An ultrasonic welding machine refers to a machine that utilizes the principle of ultrasonic waves. It generates high-voltage and high-frequency signals through a generator and converts them into high-frequency mechanical vibrations. The high-frequency mechanical vibrations cause frictional heat to be generated at the contact surface between the electrode sheet and the tab to be welded. The frictional heat raises the temperature of the contact surface to the melting state, and after cooling, the electrode sheet and the tab are welded together.

[0003] The existing ultrasonic welding machine includes a machine base. A fixed fixture for clamping and fixing the cell is arranged on the machine base, and a welding head is arranged on the top of the fixed fixture. The welding head performs welding operations on the electrode sheet and the tab on the fixed fixture.

[0004] However, when the ultrasonic welding machine is in operation, welding slag will be generated at the welding head. The welding slag will fall due to the action of gravity. When the welding slag falls onto the cell diaphragm, the welding slag is likely to cause the diaphragm to be punctured and pose a risk of short circuit. At this time, it is difficult to ensure the ultrasonic welding effect, and the battery quality is easily affected. Summary of the Utility Model

[0010] In some implementation manners, the welding driving component includes a transmission seat and a welding driving source. The transmission seat is drivingly connected to the welding driving source, and both the welding head and the second negative pressure dust removal member are located on the transmission seat.

[0017] In summary, the present utility model has at least the following beneficial effects:

[0018] For the ultrasonic welding mechanism with an inverted welding method provided by the present utility model, during the ultrasonic welding process, the workpiece to be welded is placed in the welding area.

[0019] During the welding process, the first negative pressure dust removal component sucks the welding slag generated at the welding seat, while the second negative pressure dust removal component sucks the welding slag generated at the welding head. The welding slag falls due to its own gravity and is timely subjected to negative pressure dust removal through the dust removal component. Compared with the traditional ultrasonic welding mechanism, the workpiece to be welded can improve the risks of diaphragm puncture and short circuit that occur when falling onto the battery core diaphragm through inverted welding and the dust removal component absorbing the welding slag, which is beneficial to ensuring the ultrasonic welding effect and further reducing the impact on the battery quality.
