Abstract

The invention is an ultrasonic welding head applicable to automobile dashboard glass welding. The ultrasonic welding head applicable to automobile dashboard glass welding comprises a welding head body provided with welding bumps on the ultrasonic generating surface and is characterized in that the welding head body is cylindrical, the middle portion of the welding head body is provided with an energy diversity opening, one side of the upper portion of the welding head body is provided with a shaping notch, the other side of the welding head body is provided with a shaping flat opening perpendicular to the tangent plane, and the welding bumps comprise inner welding bumps arranged around the energy diversity opening, upper welding bumps arranged on the upper side of the ultrasonic generating surface and lower welding bumps arranged on the lower side of the ultrasonic generating surface. The ultrasonic welding head applicable to automobile dashboard glass welding has the advantages of being capable of ensuring shock equilibrium during welding due to the unique design and ensuring that the contact surface difference between the welding surface of the welding head and the glass surface of a workpiece does not exceed 0.05mm, thereby meeting requirements of the accuracy and quality of welding.

Description

Technical field [0001] The present invention involves an ultrasonic welding head, especially an ultrasonic welding head suitable for the glass welding of the car dashboard. Background technique [0002] At present, when the glass of welding car dashboard is glass, the design structure of the automotive duty panel is complicated, the design is more gully, and the designed welding connection surfaces are uneven. The use of traditional welding heads during welding will cause a large problem of shocks, which will leadThe welding quality of the workpiece does not meet the accurate qualification standards. Invention content [0003] The purpose of the present invention is to provide an ultrasonic welding head suitable for the glass welding of the car instrument panel to solve the problem of inaccurate welding of the instrument panel. [0004] The technical solution used to solve its technical problems of the present invention is: [0005] A ultrasonic welding head suitable for the gla...
