[0002] The lithium battery shell is used to protect the internal lithium battery to prevent the lithium battery from being damaged. The lithium battery shell will be welded during production. Ultrasonic waves are used to increase the temperature transferred to the interface due to the friction between the surface and molecules of the workpiece. When the melting point of the workpiece is reached, the interface of the workpiece melts rapidly for welding.
[0003] A self-positioning welding device for a lithium battery shell with application number "CN202221913313.2" is provided, in which a mounting rod is installed on one side of the welding table, a positioning screen is installed on the top of the mounting rod, and an industrial camera is installed at the bottom of the mounting shell. The industrial camera can take pictures of the position where the workpiece is placed. The industrial camera is electrically connected to the positioning screen. The industrial position photographed by the industrial camera will be displayed through the positioning screen. When placing the shell, the staff can place it by observing the positioning screen, so that the shell can be placed more accurately. However, when placing the lithium battery shell, the above scheme places it according to the observation of the positioning screen, but it does not set a limiting positioning part. When placing it, the lithium battery shell needs to be adjusted to the appropriate position many times, and the positioning efficiency is poor. At the same time, after the lithium battery shell is welded, it is necessary to remove, re-place and position the lithium battery shell to be welded. This placement and positioning process takes up extra time, affecting the welding efficiency. Utility Model Content

[0009] According to the novel ultrasonic welding press-fitting mechanism, the lower ends of the two threaded blocks are both slidably connected to the bottom wall of the mounting groove.
[0010] According to the novel ultrasonic welding press-fitting mechanism, four corners of the lower end of the workbench are fixedly connected with columns.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. This novel ultrasonic welding pressing mechanism drives the positioning block to move by setting a dual-axis motor, a threaded rod, and a threaded block.
