Description

Technical Field

[0001] This invention relates to the field of high-power ultrasonic technology, specifically to an ultrasonic system used under hard-on-hard conditions. Background Technology

[0002] A head-on collision is a special case in ultrasonic applications, and one that presents a significant challenge. Theoretically, under such conditions, existing ultrasonic systems will inevitably damage the transducer. This is because the power supply can output a large amount of power, while the tool head can only output a small amount (or, in other words, the actual power consumed by the load is very low—simply put, it's like putting the car in neutral and then accelerating). Therefore, the transducer is very likely to be overloaded and damaged. However, due to application requirements, this is difficult to avoid. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the present invention aims to provide an ultrasonic system for use under hard-on-hard conditions. By increasing the thickness and diameter of the aluminum gasket and making its edges serrated, the heat dissipation capacity is greatly increased, allowing the heat dissipated from the inside of the 20k inverted horn transducer to be quickly dissipated, thereby facilitating the improvement of the power input efficiency of the 20k inverted horn transducer.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] An ultrasonic system for use under head-on collision conditions includes an ultrasonic driving power supply, the output of which is electrically connected to a 20k inverted horn transducer.

[0006] The 20k inverted horn transducer includes a central screw, a rear cover plate threadedly connected above the surface of the central screw, an aluminum clamping gasket threadedly connected in the middle of the central screw, piezoelectric ceramics disposed on the upper and lower outer walls of the aluminum clamping gasket, aluminum gaskets disposed on the upper and lower outer walls of the piezoelectric ceramics, and a front cover plate threadedly connected below the surface of the central screw.

[0007] Through the above technical solutions, by making the outer surface of the aluminum pad 1 serrated and by making the aluminum pad 1 conformal design and processing, the contact area is increased, the unit contact pressure of the aluminum pad 1 is reduced, and the power input efficiency is improved. By increasing the thickness of the aluminum pad 1, the heat conduction capacity is greatly increased, and the heat generated by the energy conversion inside the 20k inverted horn transducer can be quickly dissipated, thus improving the heat dissipation efficiency. By increasing the diameter of the aluminum pad 1 and changing the edge to serrated, the heat dissipation capacity is greatly increased, and the heat dissipated from inside the 20k inverted horn transducer can be quickly dissipated, thus achieving the effect of facilitating the improvement of the power input efficiency of the 20k inverted horn transducer.

[0008] By clamping a fixed coupling medium between the piezoelectric ceramic and the aluminum pad, the coupling medium is a solid coupling material. The piezoelectric ceramic is the output and the aluminum pad is the load. Adding the coupling medium increases the power of the ultrasonic drive power supply. The input and output efficiency between the piezoelectric ceramic and the aluminum pad is increased through the coupling medium, thereby preventing the 20k inverted horn transducer from overloading.

[0009] By starting the isolation protection unit with 220V AC mains power, the drive current or power limit of the ultrasonic drive power supply can be limited. For power supplies with constant power output, we limit the current and voltage, thus ensuring the output of the ultrasonic drive power supply while limiting excessive output, protecting the 20k inverted horn transducer. The voltage detection module, current detection module, transducer detection module, and temperature detection module in the sampling unit limit the current and voltage within the acceptable range of the 20k inverted horn transducer. The ultrasonic waves from the ultrasonic drive power supply can be used on traditional hard-to-hard loads, the ultrasonic system is less prone to damage, the user experience is greatly improved, and the application range of ultrasonic waves is expanded.

[0010] Preferably, a coupling medium is clamped and fixed between the piezoelectric ceramic and the aluminum gasket, and there are four sets of piezoelectric ceramics.

[0011] The above technical solution involves clamping a fixed coupling medium between the piezoelectric ceramic and the aluminum pad, which is a solid coupling material. The piezoelectric ceramic is the output, and the aluminum pad is the load. By adding the coupling medium, the power of the ultrasonic drive is increased, and the input and output efficiency between the piezoelectric ceramic and the aluminum pad is increased, thereby preventing the 20k inverted horn transducer from overloading.

[0012] Preferably, the outer surface of the aluminum gasket is serrated, and there are two sets of the aluminum gasket located above the front cover and below the rear cover, respectively.

[0013] Through the above technical solutions, by making the outer surface of the aluminum pad serrated and processing it in a contoured manner, the contact area is increased, the unit contact pressure of the aluminum pad serrated is reduced, and the power input efficiency is improved. The thickness of the aluminum pad serrated is increased, which greatly increases the heat conduction capacity. The heat generated by the energy conversion inside the 20k inverted horn transducer can be quickly dissipated, improving the heat dissipation efficiency. The diameter of the aluminum pad serrated is increased and the edge is made serrated, which greatly increases the heat dissipation capacity. The heat dissipated from inside the 20k inverted horn transducer can be quickly dissipated.

[0014] Preferably, the surface of the aluminum pad has a ring-shaped array of heat dissipation holes, and the output terminal of the ultrasonic drive power supply is connected to a piezoelectric ceramic.

[0015] The above technical solution uses aluminum alloy as the clamping pad, which facilitates heat dissipation. The surface of the clamping pad has a ring array of heat dissipation holes, which greatly improves the heat dissipation efficiency. Moreover, the impedance is controlled within a reasonable range, or in other words, the impedance has increased, but it is still within the allowable range. The output terminal of the ultrasonic drive power supply is connected to the piezoelectric ceramic.

[0016] Preferably, the aluminum gasket, piezoelectric ceramic, and aluminum gasket are all clamped above the front cover and below the rear cover.

[0017] The above technical solution uses a central screw to clamp the aluminum gasket, piezoelectric ceramic, and aluminum gasket 1 above the front cover and below the rear cover, thus fixing the aluminum gasket, piezoelectric ceramic, and aluminum gasket 1, and providing convenient protection for the front and rear cover plates.

[0018] Preferably, the ultrasonic driving power supply includes 220V AC mains power. The output terminals of the 220V AC mains power are respectively fixedly connected to a rectification filter and an isolation protection unit. The output terminal of the rectification filter is fixedly connected to an LGBT full-bridge inverter. The output terminal of the LGBT full-bridge inverter is fixedly connected to an isolation step-up transformer. The output terminal of the isolation step-up transformer is fixedly connected to an LC resonant network matching. The output terminal of the LC resonant network matching is fixedly connected to a sampling unit. The output terminals of both the sampling unit and the isolation protection unit are fixedly connected to a data processing unit. The output terminals of the data processing unit are respectively fixedly connected to the isolation step-up transformer and the LC resonant network matching.

[0019] The above technical solution utilizes a 220V AC mains-powered isolation protection unit to limit the drive current or power limit of the ultrasonic drive power supply. For a power supply with a fixed power output, we limit both current and voltage, thus ensuring the output of the ultrasonic drive power supply while limiting excessive output, protecting the 20kHz inverted horn transducer.

[0020] Preferably, the sampling unit includes a voltage detection module, a current detection module, a transducer detection module, and a temperature detection module.

[0021] Through the above technical solution, the current and voltage are limited to the acceptable range of the 20k inverted horn transducer by means of the voltage detection module, current detection module, transducer detection module and temperature detection module in the sampling unit.

[0022] Preferably, the output terminals of the voltage detection module, current detection module, transducer detection module, and temperature detection module are respectively connected to the data processing unit, and the input terminals of the voltage detection module, current detection module, transducer detection module, and temperature detection module are respectively connected to the LC resonant network matching.

[0023] The above technical solution connects the input terminals of the voltage detection module, current detection module, transducer detection module, and temperature detection module to an LC resonant network for matching, which facilitates limiting the current and voltage to within the acceptable range of the 20k inverted horn transducer.

[0024] Preferably, the output terminal of the LC resonant network is fixedly connected to a 20k inverted horn transducer.

[0025] Through the above technical solution, a 20k inverted horn transducer is fixedly connected to the output terminal of the LC resonant network. The ultrasonic drive power supply is connected to the 20k inverted horn transducer. The ultrasonic waves of the ultrasonic drive power supply can be used on traditional hard-to-hard loads. The ultrasonic system is not easily damaged, the user experience is greatly improved, and the application range of ultrasonic waves is expanded.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0027] First, this invention increases the contact area and reduces the unit contact pressure of the aluminum pad by making the outer surface of the aluminum pad serrated and processing it in a contoured manner, thereby improving the power input efficiency. Increasing the thickness of the aluminum pad greatly increases its thermal conductivity, allowing the heat generated by the energy conversion inside the 20k inverted horn transducer to dissipate quickly, thus improving heat dissipation efficiency. Furthermore, increasing the diameter of the aluminum pad and making the edges serrated further enhances its heat dissipation capacity, allowing the heat dissipated from inside the 20k inverted horn transducer to dissipate quickly, thus facilitating the improvement of the power input efficiency of the 20k inverted horn transducer.

[0028] Secondly, the present invention uses a fixed coupling medium sandwiched between the piezoelectric ceramic and the aluminum pad, which is a solid coupling material. The piezoelectric ceramic is the output and the aluminum pad is the load. By adding the coupling medium, the power of the ultrasonic drive is increased. The input and output efficiency between the piezoelectric ceramic and the aluminum pad is increased through the coupling medium, thereby preventing the 20k inverted horn transducer from overloading.

[0029] Third, this invention utilizes a 220V AC mains-activated isolation protection unit to limit the driving current or power limit of the ultrasonic drive power supply. For a power supply with a fixed power output, we limit the current and voltage, thus ensuring the output of the ultrasonic drive power supply while limiting excessive output, protecting the 20k inverted horn transducer. The voltage detection module, current detection module, transducer detection module, and temperature detection module within the sampling unit limit the current and voltage to within the acceptable range of the 20k inverted horn transducer. The ultrasonic waves from the ultrasonic drive power supply can be used on traditional hard-to-hard loads, the ultrasonic system is less prone to damage, the user experience is greatly improved, and the application range of ultrasonic waves is expanded.
