[0002] Ultrasonic welding positioning fixture is a special welding processing fixture used to assist in the fixation of ultrasonic welding. Ultrasonic welding is a process that uses high-frequency vibration energy to weld two or more materials. This technology is widely used in the automotive, electronics, medical and packaging industries. Ultrasonic welding positioning fixture can assist in the clamping and positioning of welded parts or molds during ultrasonic welding.

[0003] Based on the above, ultrasonic welding is widely used in many industries.
