[0002] At present, the automobile development process requires luxurious and high-end configurations, which determines that the development and processing of parts are more angles. Different parts need to be combined together through welding to achieve a double breakthrough in function and appearance. The different angles determine that the welding process must use high-angle welds to meet actual production needs.

[0003] The angle of existing welding structure products generally does not exceed 45°. At the same time, the product samples are relatively small. Ultrasonic welding is generally used for large product sizes to meet the needs of multiple angles. However, ultrasonic welding takes a long time due to single-point control, and the equipment investment is relatively large, so a separate robot mechanism is required to meet the needs.

The relative clamping and fixation of the upper and lower templates can keep the fetal membrane in a stable state. In addition, the oblique push cylinder can be set to a large inclination angle of more than 45° according to needs, which can not only adapt to large-angle inclined welding processes, but also ensure the stability of the welding process and the welding yield, ensure the consistency and quality stability of the product, and control the clamping and displacement process before welding through the cylinder to improve the efficiency and stability of the welding process.
