The welding mask can ensure a good sealing effect. If an ultrasonic welding machine with an ejection mechanism disclosed in patent number CN202321517383.0 is used, it relates to the technical field of ultrasonic welding machines, and improves the situation where the welding machine is trapped in the tooling and is inconvenient to take. It includes a machine, a lower tooling is arranged in the middle of the upper surface of the machine, a slider is slidably connected to the inner side of the lower tooling, a top plate is fixedly connected to the outer surface of the slider, a bidirectional motor is fixedly connected to the inner side of the machine, a shaft is fixedly connected to the driving end of the bidirectional motor, a turntable is fixedly connected to the end of the shaft away from the bidirectional motor, and a push rod is movably connected to the outer surface of the turntable. The application can drive the operation of the shaft, turntable, push rod and top plate through the double-headed motor to drive the welded parts placed inside the slider to move upward from the lower tooling, and the welded parts are moved out from the lower tooling to facilitate the staff to take the welded parts.

[0003] When welding the mask, the disadvantage of using the above-mentioned welding mechanism is that since the shape of the welded mask is mostly arc-shaped, it cannot be effectively integrated by welding, and the wires of the welded transducer and the control box are fixedly connected, and the welding structure cannot separate the transducer and the control box during the cleaning stage. For this reason, we designed an ultrasonic welding mechanism for the electric vehicle headlight mask. Summary of the invention
