Abstract
The present invention relates to the technical field of ultrasonic transducer more particularly to a kind of ultrasonic transducers that ultrasonic welding is used on bonding equipment.The energy converter head is for installing porcelain mouth, and work vibration shape is at least there are two node, and piezo-electric crystal, which is in, leans on caudal node, and mounting flange is in another node.One important feature of the energy converter is that piezo-electric crystal is disposed adjacent at the node of tail portion, and the pre- acquisition for answering pressure that piezo-electric crystal needs does not have to screw locking, energy converter has rotary inertia small, and piezo-electric crystal answers pressure not influenced by installation in advance, and variation will not be generated because of loosened screw.So that energy converter can swung up and down faster, bonding equipment speed of production is improved, while the stability of energy converter is guaranteed.
Description
Technical field
The present invention relates to the technical field of ultrasonic transducer more particularly to it is a kind of on bonding equipment for ultrasonic welding
Ultrasonic transducer.
Background technique
Bonding equipment is widely used in semiconductor packaging industry.Energy converter is as one of the 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 of bonding equipment is proposed higher and higher
Requirement.
In bonding equipment operational process, the energy converter on bonding equipment is swung up and down at a high speed under motor drive,
Body generates ultrasonic vibration by receiving electric drive and converts electric energy to ultrasonic vibrational energy and be transmitted to porcelain mouth, so that porcelain mouth is along changing
Energy device axis direction is vibrated back and forth with supersonic frequency.
With being getting faster for the high-speed full-automatic bonding equipment speed of service, it is desirable that energy converter rotary inertia itself is smaller more
Good, performance in use remains unchanged for a long time, there is extraordinary stability.
Since the factor for influencing transducer characteristics and quality is very more, along with the high-speed production applied in accurate chip
On, good energy converter will take into account every aspect on designing and manufacturing.Need largely design, test and Optimization Work.Its
In mostly important principle be when making design for certain particular demands to improve, to avoid in terms of other needs are taken into account
Meet application requirement simultaneously.
Summary of the invention
The present invention is designed a kind of energy converter, is pacified using flange form by fermenting, calculating, testing and using verifying repeatedly
Dress, piezo-electric crystal are pre- that pressure is answered to guarantee by transducer body side muscle close to body tail section.
The technical scheme is that, it is characterised in that: porcelain mouth (2) are installed on the head of transducer body (1), piezo-electric crystal
(4) it is arranged at the node (13) of ontology (1) tail portion, mounting flange (3) is disposed adjacent to another section near ontology (1) centre
At point (12), pre- in ontology (1) of piezo-electric crystal (4) answers pressure by two sides muscle (6) to keep.
The influence installed is received utmostly to reduce transducer ultrasonic characteristic after installation, is paid the utmost attention to used in ontology (1)
Slot (7) are set at flange (3).
The substantially same piezo-electric crystal of the width up and down of side muscle (6), transverse gage is preferentially between 0.7 millimeter to 1.0 millimeters, edge
Ontology longitudinal length is preferentially between 7.5 millimeters to 8.0 millimeters.

Specific embodiment
At least there are two node, the heads of transducer body (1) for energy converter as shown in Figure 1: for one embodiment of the present of invention
For installing porcelain mouth (2), piezo-electric crystal (4) is arranged at the node (13) of ontology (1) tail portion, and mounting flange (3), which is arranged in, to be leaned on
At another node (12) near nearly ontology (1) centre, pre- in ontology (1) of piezo-electric crystal (4) answers pressure by two sides muscle (6)
To keep.
Second embodiment of the invention is as shown in figure 4, on the basis of first implementation column, the method on ontology (1)
A slot (7) is opened at blue (3), further to improve mounting characteristics.
The following size is preferentially used to make transducer characteristics be in optimally band, side muscle: the substantially same piezo crystals of upper and lower width
Body, transverse gage is between 0.7 millimeter to 1.0 millimeters, along ontology longitudinal length between 7.5 millimeters to 8.0 millimeters.
