Description

Technical Field

[0001] This utility model relates to the field of ultrasonic power supplies, and in particular to an ultrasonic power supply and operating equipment. Background Technology

[0002] Ultrasonic waves are widely used in various fields, such as ultrasonic welding and cutting. Ultrasonic welding is a process that uses high-frequency sound wave vibrations (typically 15-60 kHz) to generate frictional heat and mechanical pressure at the material interface, fusing two or more material interfaces together to achieve a solid-state connection. Besides welding, in materials science, ultrasonic technology is also used for material modification, cutting, and many other applications. The ultrasonic waves generated by an ultrasonic generator can induce changes in the microstructure and properties of materials, achieving material modification. Ultrasonic cutting technology utilizes the impact and shearing forces generated by ultrasonic vibrations to precisely and rapidly cut materials. The core advantages of ultrasonic welding include: 1. Non-melting bonding: No need for high-temperature melting of materials, reducing the heat-affected zone, suitable for heat-sensitive materials (such as plastics and thin metals). 2. High efficiency and environmental friendliness: Short welding time (typically less than 1 second), no need for solder or flux, reducing pollution and material loss. 3. High precision and flexibility: Can weld small parts and adapt to various material combinations (such as metals, plastics, and ceramics).

[0003] Currently, the control chip in ultrasonic power supplies not only needs to control the generation of ultrasonic waves, but also needs to handle other functions, such as communication with external devices. This can cause the control chip to consume loop time while handling other functions during cyclic control, resulting in inaccurate ultrasonic output and ultimately affecting the quality of the work. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this invention provides an ultrasonic power supply that, by incorporating an ultrasonic control module and an auxiliary control module, operates in a dual-channel simultaneous manner, thereby significantly improving the accuracy and efficiency of ultrasonic wave generation. This invention also provides an application device.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

The feedback signal includes the operating parameter signals of the ultrasonic generator module.

[0011] By adopting the above technical solution, the ultrasonic control module and the auxiliary control module operate simultaneously. The ultrasonic control module primarily generates control signals to enable the ultrasonic generator to produce ultrasonic waves. The auxiliary control module handles functions other than generating control signals, significantly improving the accuracy and efficiency of ultrasonic wave generation and the accuracy and efficiency of controlling other functions. This technical solution avoids the problem of a single control module consuming loop time for non-control signal generation during cyclic control. Specifically, when a single control module is processing non-control signal generation, it cannot update the control signals in a timely manner, leading to inaccurate and inefficient ultrasonic wave generation.

[0012] Furthermore, the auxiliary control module is communicatively connected to the ultrasonic control module.

[0039] Furthermore, the multi-phase controllable drive signals output by the full-bridge phase-shifting circuit are four signals;

[0040] The IGBT drive circuit includes a first push-pull circuit block, a second push-pull circuit block, a third push-pull circuit block, a fourth push-pull circuit block, a first isolation transformer, and a second isolation transformer. The first isolation transformer has one primary coil and two secondary coils, and the second isolation transformer has one primary coil and two secondary coils.

[0041] The input terminal of the first push-pull circuit block is connected to the corresponding drive signal among the multiple phase-controllable drive signals, and the output terminal is connected to one end of the primary coil of the first isolation transformer. The input terminal of the second push-pull circuit block is connected to the corresponding drive signal among the multiple phase-controllable drive signals, and the output terminal is connected to the other end of the primary coil of the first isolation transformer.

One secondary coil of the second isolation transformer is connected to the third IGBT drive circuit block, and the other secondary coil is connected to the fourth IGBT drive circuit block.

[0043] By adopting the above technical solution, the full-bridge phase-shifting circuit and the IGBT driving circuit are made more reasonable. The arrangement of the first push-pull circuit block, the second push-pull circuit block, the third push-pull circuit block, and the fourth push-pull circuit block can not only amplify the power of the corresponding driving signals respectively, providing appropriate driving current for the subsequent driving of the IGBT circuit, but also adjust the output impedance to achieve better impedance matching between the signal source and the load, thereby improving energy transfer efficiency. Furthermore, the arrangement of the first push-pull circuit block, the second push-pull circuit block, the third push-pull circuit block, and the fourth push-pull circuit block can also improve the switching speed, providing fast switching signals for power devices such as IGBTs, reducing losses during the switching process, and improving overall efficiency.

[0044] The first isolation transformer and the second isolation transformer are designed to effectively achieve isolated output and prevent downstream faults from burning out the upstream circuit. Specifically, the first isolation transformer and the second isolation transformer have the same manufacturing parameters.

[0045] Furthermore, the output circuit includes an output transformer and an output inductor. The primary coil of the output transformer is connected to the output structure of the IGBT circuit.

[0075] The phase comparison unit is connected to the signal generation unit to feed back the phase relationship signal acquired by the phase comparison unit to the signal generation unit.

[0076] The signal generation unit is used to generate a reference signal of a specific form based on the control signal of the ultrasonic control module, the amplitude signal fed back by the amplitude acquisition unit, and the phase relationship signal fed back by the phase comparison unit.

[0077] By adopting the above technical solution, the ultrasonic power supply is made more reasonable. The amplitude acquisition unit and the phase comparison unit transmit the acquired data to the ultrasonic control module, and then the ultrasonic control module sends it to the signal generation unit. There will be a certain delay. Therefore, in this technical solution, the amplitude acquisition unit and the phase comparison unit not only send the acquired data to the ultrasonic control module, but also send it to the signal generation unit, so that the signal generation unit can update the reference signal in a timely manner.
