Ultrasonic welding equipment

The utility model discloses ultrasonic welding equipment, and relates to the technical field of ultrasonic welding equipment. The ultrasonic hot melting assembly comprises an ultrasonic hot melting mechanism, and the ultrasonic hot melting mechanism is installed on the base frame; the material assembly comprises a jig and a first driving mechanism, the jig is arranged below the ultrasonic hot melting mechanism, the jig is provided with at least two profiling blocks, each profiling block is provided with a profiling groove used for containing a workpiece, and the first driving mechanism is used for driving the jig to move. During welding, after the ultrasonic hot melting mechanism welds a workpiece in one profiling block, the position of the jig is changed through the first driving mechanism so that the ultrasonic hot melting mechanism can conveniently weld the workpiece placed in the other profiling block, and the situation that the workpiece needs to be replaced when each workpiece is welded is avoided; ther
