Embodiment

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

Refer to Fig. 1. Notice, structure that this specification sheets institute accompanying drawings illustrates, ratio, size etc., all only content in order to coordinate specification sheets to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore do not have an essential meaning in technology, the adjustment of the modification of any structure, the change of proportionlity or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain. Simultaneously, this specification sheets is quoted as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and it is not used to limit the enforceable scope of the utility model, the change of its relative relation or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.

As shown in Figure 1, the utility model provides a kind of ultrasonic bonding machine frame, and this frame comprises ultrasonic generator 1, transverter 2 and soldering tip 3 three parts, and ultrasonic generator 1 is connected with transverter 2, and transverter 2 is connected with soldering tip 6 by horn 5. Ultrasonic generator 1 for converting 15,20,30 or 40KHz electric energy to by 50/60 hertz of electric current, transverter 2 can convert electric energy to the mechanical movement into equal frequencies, pass to soldering tip 6 by horn 5 again, drive soldering tip 6 to carry out vibration friction at body surface. Transverter 2 mainly utilizes the piezoelectric effect of some single crystal material and the electrostrictive effect of some polycrystalline material to realize the conversion of electric energy to mechanical energy.

Transverter 2 is positioned at a permanent seat 3, and permanent seat 3 is provided with a through hole, and transverter 2 is positioned at this through hole. Also being provided with the first holding ring 4 and the 2nd holding ring 7, first holding ring 4 in through hole for clamping transverter 2, when the position that the first holding ring 4 clamps is positioned at transducer vibrations, amplitude is the transverter node location of zero. 2nd holding ring 7 is for clamping horn 5, and it is the horn node location of zero that the position that the 2nd holding ring 7 clamps is positioned at amplitude when horn 5 is vibrated. Like this in vibration friction welding (FW) working process, the first holding ring 4, the 2nd holding ring 7 can not produce vibration, thus can effectively reduce the power loss of welding machine.

As a kind of optimal way, permanent seat 3 can be divided into first permanent seat and second permanent seat two portions, first permanent seat is connected by screw with second permanent seat, the installation of the first holding ring 4, the 2nd holding ring 7, transverter 2 and horn 5 can be facilitated like this, particularly it is convenient to the position adjustments of holding ring on transverter or horn.

As a kind of embodiment, two grooves can be provided with on the inner peripheral surface of permanent seat 3, the first holding ring 4, the 2nd holding ring 7 are stuck in two grooves and are positioned by holding ring. as another kind of embodiment of this patent, twice arc convex tendon can be set respectively on the inner peripheral surface of first permanent seat with second permanent seat, first permanent seat is corresponding with the arc convex tendon position on second permanent seat, when first permanent seat and second permanent seat link together, twice arc convex tendon on upper lower fixed seat can form twice ring structure, this twice ring structure also can be used as the first holding ring 4 and the 2nd holding ring 7, adopt the dynamics of this kind of structure clamping bigger, transverter 2 can be lowered so to a certain extent and stress that horn 5 node location is subject to. owing to arc convex tendon can exist certain thickness, therefore holding ring clamping transverter 2 or horn 5 it is possible to there will be some vibration, such welding machine will send noise in working process, therefore vibration isolation rubber can be set between the first holding ring 4 and transverter 2 and between the 2nd holding ring 7 and horn 5, noise when welding machine works can be reduced like this.

This ultrasonic bonding machine frame arranges the first holding ring and the 2nd holding ring in permanent seat, and amplitude is the node location of zero when the position of the first holding ring, the 2nd holding ring is clamped in transverter and the vibration of vertically hung scroll bar respectively, like this when transducer vibrations, the position of the first holding ring, the 2nd holding ring clamping almost can not produce any vibration, so just can effectively reduce the power loss of transverter and vertically hung scroll bar, it is to increase the working efficiency of welding machine. So, the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.

Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model. Above-described embodiment all not running counter under spirit of the present utility model and category, can be modified or change by any person skilled in the art scholar.
