Description

Technical Field

[0001] This utility model relates to the field of rotary ultrasonic welding, and in particular to a welding fixture for a rotary ultrasonic welding machine. Background Technology

[0002] The existing rotary ultrasonic welding equipment has the following structure: Figure 1 As shown, when the turntable rotates the product to the ultrasonic welding station, the ultrasonic welding mechanism presses down to perform welding. After welding, the ultrasonic welding mechanism returns to its original position, and the tooling fixture rotates to proceed to the next process.

[0003] However, each time the product is changed, only the welding head is replaced, and the change requires entering the equipment. After replacing the welding head, the position needs to be adjusted through the fine-tuning base A. The debugging time is long, the change is difficult, and the operation skills of the workers are required, which is not conducive to production. Moreover, the fine-tuning base A is relatively heavy, making the initial and later debugging difficult. Utility Model Content
