Abstract

The invention discloses an ultrasonic welding head. The ultrasonic welding head comprises a handle, a variable arc rod, a swinging arc rod, a reducing part and welding teeth, wherein the variable arc rod is connected to one end of the handle, and the cross-sectional area of the variable arc rod is less than that of the handle; the swinging arc rod is connected to one end, which is far from the handle, of the variable arc rod, and the cross section of the swinging arc rod is approximately in a rectangular shape; the reducing part is arranged on at least one side surface of the swinging arc rod, in the direction from the free end of the reducing part to the swinging arc rod, the cross-sectional area of the reducing part is gradually increased, and one side surface, which is far from the handle, of the reducing part is flush with the end surface of the free end of the swinging arc rod; and the welding teeth are arranged on the end surface of the free end of the reducing part. According to the ultrasonic welding head, the reducing part is arranged, so that energy loss during ultrasonic welding can be reduced, the service life of the ultrasonic welding head is prolonged, and bad defects of false welding, over welding and the like when products are welded are avoided.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an ultrasonic welding head. Background technique [0002] In the related art, the ultrasonic energy loss is relatively large when the welding head welds metal, which leads to a short service life of the ultrasonic welding head, and brings bad defects such as false welding and over welding to product welding. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an ultrasonic welding head, which is beneficial to reducing the energy loss of ultrasonic waves and prolonging the service life of the welding head. [0004] The ultrasonic welding head according to the embodiment of the present invention includes: a handle; a variable arc rod connected to one end of the handle, and the cross-sectional area of ​​the variable arc rod is smaller than that of ...
