Problems solved by technology
However, in the existing ultrasonic welding, the ultrasonic system needs to be disassembled when the tool head is replaced, resulting in a decrease in the stability of the ultrasonic system, and it will also cause changes in the position of the tool head and the worktable, which will affect the processing efficiency and increase the economic cost.
When the tool head is worn, the frequency of the ultrasonic system drifts, causing the position of the wave peak to deflect and affecting the welding quality
Moreover, in the existing ultrasonic welding, only one type of tab can be welded, which cannot expand production and affect production efficiency.

The invention discloses a multifunctional adjustable tab ultrasonic welding system. The system comprises a cylinder, a vibration mechanism and a workbench. The cylinder is disposed at the upper end ofa bracket, the lower end of the bracket is connected to a base, and a piston rod of the cylinder is connected with a lifting plate. A guide rail pair is arranged between the lifting plate and the bracket. The vibration mechanism comprises a transducer and an ultrasonic amplitude-change pole which are connected through a bolt. The transducer is connected with an ultrasonic generator. A die head isarranged on the ultrasonic amplitude-change pole. The vibration mechanism is connected with the lifting plate. The base is provided with the workbench, and the upper end face of the workbench corresponds to the die head. The angle of the die head can be quickly adjusted, so that the die head is perpendicular to the workbench, and the welding quality is guaranteed. In addition, the system is applicable to welding of various tabs, realizes multifunctional adjustable welding, is simple to operate, and greatly improves the welding quality and welding efficiency of the tabs.
Description
Technical field: [0001] The invention relates to the field of lithium battery tab welding, in particular to a multifunctional adjustable tab ultrasonic welding system Background technique: [0002] With the continuous development and innovation of electronic products, higher requirements are put forward for the high-rate charge and discharge of lithium batteries, and the quality of lithium battery tab welding is a key factor affecting its performance. Ultrasonic welding has become a widely used welding method in tab welding due to its advantages of speed, environmental protection and stability. However, in the existing ultrasonic welding, the ultrasonic system needs to be disassembled when the tool head is replaced, which leads to a decrease in the stability of the ultrasonic system, and also causes changes in the position of the tool head and the worktable, which affects the processing efficiency and increases the economic cost. When the tool head is worn, the frequency of...
