Abstract
The utility model relates to the technical field of ultrasonic transducers, in particular to an ultrasonic transducer used for ultrasonic welding on a wire welding machine. According to the ultrasonic transducer, a piezo-electric crystal is located in the middle, and meanwhile, stretching ribs at the joint positions on the front edge and the rear edge of the piezo-electric crystal are connected with flanges used for installation. Due to the fact that the ribs supporting the transducer are led out of the two different positions in the axis direction of the transducer, bending rigidity of the transducer can be easily guaranteed; meanwhile, because the ribs are led out from the vibration joint positions of the transducer and the vibration amplitude of the transducer is the minimum at the vibration joint positions, interference suffered from installed positions on the transducer is minimized after the transducer is installed on a machine.
Description
Technical field
The utility model relates to the technical field of ultrasonic transducer, relate in particular to a kind of on bonding equipment the ultrasonic transducer for ultra-sonic welded.
Background technology
Bonding equipment is widely used in semiconductor packages industry.Transducer, as one of critical component on bonding equipment, has material impact to the performance of bonding equipment.Along with the development of semiconductor packages industry, the speed of service of bonding equipment is proposed to more and more higher requirement.The speed of service of bonding equipment can arrive welding 20 lines per second.In addition, different types of slice, thin piece is more and more, requires bonding equipment can be applicable to the welding demand of multiple different slice, thin pieces, comprises the QFN that is relatively difficult to welding.
In bonding equipment running, the transducer being contained on bonding equipment moves up and down at a high speed under motor driving, itself produces ultrasonic vibration and converts electric energy to ultrasonic vibrational energy and be delivered to porcelain mouth by accepting electric drive, and porcelain mouth is vibrated with supersonic frequency back and forth along transducer axis direction.
More and more faster along with the high-speed full-automatic bonding equipment speed of service, the weight of transducer itself starts to become a bottleneck.Need to there is light-duty transducer.
In addition, transducer is in when work, and the porcelain mouth of its clamping is with solder joint contact and be subject in vertical direction reaction force upwards, and therefore transducer head produces being bent upwards to a certain degree, the larger interference to ultrasonic vibration of degree of crook is larger, more unfavorable to ultra-sonic welded quality.Therefore in the light-duty transducer of design, must take into account the bending stiffness of not falling end transducer.
Moreover, provide transducer to be mechanically fastened on machine, in the time of work, its ultrasonic vibration is inevitably subject to the impact of installation position.Can contact area be installed by reduction and reduce the impact from installation position, but simple reduction installation contact area can cause the reduction of the bending stiffness of transducer.
Summary of the invention
The utility model technical issues that need to address are: by considering various influence factors, design a kind of transducer, both made its quality enough slim and graceful, had again enough bending stiffnesses, be arranged on machine that in the time of work, to be subject to the adverse effect of installation position little simultaneously.
An embodiment of the present utility model, is characterized in that: piezo-electric crystal is positioned at middle part, and porcelain mouth is clamped in transducer one end by locking porcelain mouth screw; Before having on vibration nodal point position between middle piezo-electric crystal and porcelain mouth, muscle stretches out, and on front muscle, is connected with forward flange; After having on the vibration nodal point position between piezo-electric crystal and the other end of transducer, muscle stretches out, and on rear muscle, is connected with rear flange, and forward flange 10 is not directly connected with rear flange 11.
Another embodiment of the present utility model, is characterized in that: piezo-electric crystal is positioned at medium position, and porcelain mouth is clamped in transducer one end by locking porcelain mouth screw; Before having on vibration nodal point position between middle piezo-electric crystal and porcelain mouth, muscle stretches out; After having on the vibration nodal point position between piezo-electric crystal and the other end of transducer, muscle stretches out; Front muscle and rear muscle link together, and centre is connected with flange.
