Abstract
The utility model is related to the technical field of ultrasonic transducer, more particularly to a kind of oscillator for ultrasonic transducer for being used for ultra-sonic welded on bonding equipment.This oscillator for ultrasonic transducer, except with it is common be directly subject to extraneous electricity input to drive and produce vibration deformation by electric drive piezo-electric crystal in addition to, this piezo-electric crystal with also have between transducer body it is non-by electric drive piezo-electric crystal as transition zone.It is non-by electric drive piezo-electric crystal by setting up, can suitably ultrasonic wave transmission further optimized.
Description
Technical field
The present invention relates to the technical field of ultrasonic transducer, more particularly to a kind of it is used for ultra-sonic welded on bonding equipment
Oscillator for ultrasonic transducer.
Background technology
Bonding equipment is widely used in semiconductor packaging industry.Transducer is used as one of critical component on bonding equipment, butt welding
The performance of line machine has a major impact.With the development of semiconductor packaging industry, the speed of service to bonding equipment proposes more and more higher
Requirement, all at least there are hundreds of thousands of bonding equipments to run at the same time encapsulation factory of certain scale.
With the continuous improvement of the speed of service of the high-volume use and bonding equipment of bonding equipment, as bonding equipment key portion
The importance of the ultrasonic transducer quality of part manifests further.Stability and coherence request more and more higher to transducer.
The content of the invention
In product experience and repetition test for many years, a kind of oscillator for ultrasonic transducer is found, in general design base
On plinth, piezo-electric crystal is set up as transition zone, the transmission characteristic of transducer can further be optimized.
The present invention relates to a kind of oscillator for ultrasonic transducer, it is characterised in that：Piezo-electric crystal is installed in the middle of oscillator body 1；
Voussoir 2 is provided with, causes that piezo-electric crystal is tightly pressed in hole by precompression for being pressurizeed in its one end；Piezo-electric crystal point is received
Voltage electric crystal 31,32,33,34 and non-by voltage electric crystal 41,42；By voltage electric crystal by electrode 51,52,53 by the external world
Electricity input directly converts electrical energy into mechanical energy；It is non-not directly affected by the input of extraneous electricity by voltage electric crystal, only as mistake
Cross layer.

The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is an example of the present invention schematic perspective view；
Wherein:1st, oscillator body, 2, voussoir, 31, by voltage electric crystal, 32, by voltage electric crystal, 33, by electric piezo crystals
Body, 34, by voltage electric crystal, 41, non-by voltage electric crystal, 42, non-by voltage electric crystal, 51, electrode, 52, electrode, 53, electricity
Pole.
Specific embodiment
It is as shown in Figure 1 one embodiment of the invention.Piezo-electric crystal is installed in the middle of oscillator body 1；Voussoir 2 is provided with, is used for
Pressurizeed in its one end and cause that piezo-electric crystal is tightly pressed in hole by precompression；Piezo-electric crystal point by voltage electric crystal 31,
32nd, 33,34 and non-by voltage electric crystal 41,42；Directly will by extraneous electricity input by electrode 51,52,53 by voltage electric crystal
Electric energy is converted to mechanical energy；It is non-not directly affected by the input of extraneous electricity by voltage electric crystal, only as transition zone.
