Detailed description of the invention

By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.

Refer to Fig. 1 to Fig. 3. Notice, the structure of this specification institute accompanying drawings depicted, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop on the disclosed technology contents of this utility model and obtain in the scope that can contain. Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " and " one " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.

As it can be seen, this utility model provides a kind of ultrasonic welding machine, it includes a holster shell 1, the front end of holster shell 1 is provided with work top, being provided with a cavity in holster shell 1, be provided with ultrasonic bonding frame 2 in cavity, ultrasonic bonding frame 2 is fixing with holster shell 1 to be connected.One it is additionally provided with for clamping the clamp system of ultrasonic bonding frame 2 in cavity, this clamp system includes two relative clamping plate in position, two clamping plate lay respectively on two sidewalls of cavity, two clamping plate are connected by a drive mechanism, can driving two clamping plate in the same direction or dorsad synchronizing moving by this drive mechanism, holster shell 1 is provided with adjusting knob 5. Adopting this mechanism, holster shell 1 just can clamp different clamping ultrasonic bonding frames 2, and such holster shell will have good versatility.

Ultrasonic welding machine frame includes supersonic generator 21, transducer 22, and supersonic generator 21 is connected with transducer 22, and transducer 22 is connected with soldering tip 4 by horn 25.
