Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic technology applications, specifically a device for automatic calibration of an ultrasonic amplitude transformer. Background Technology
[0002] Ultrasonic amplitude transformers are widely used in many fields, such as ultrasonic welding, ultrasonic extraction, and ultrasonic processing. Their main function is to concentrate the energy of ultrasonic vibrations and amplify the amplitude to meet the energy and amplitude requirements of different applications. In ultrasonic welding, the amplitude transformer amplifies the longitudinal vibration generated by the transducer, thereby providing sufficient energy and pressure to the welding area, enabling reliable welding of materials such as plastics and metals.
[0003] Traditional design and manufacturing issues: The design of traditional ultrasonic amplitude transformers is usually based on theoretical calculations and empirical formulas. Once their length and other parameters are determined, they are relatively fixed after manufacturing. However, in actual manufacturing, factors such as machining accuracy and differences in material properties may cause deviations between the actual resonant frequency of the amplitude transformer and the design value, affecting its performance and working efficiency. Moreover, under different working environments and conditions, such as changes in temperature, pressure, and load, the optimal working length and vibration mode of the amplitude transformer may also change.
[0004] The adjustable ultrasonic amplitude transformer has an adjustable actual operating length, allowing it to better adapt to different working environments and conditions. For example, in ultrasonic cleaning machines, the length of the amplitude transformer can be adjusted according to different cleaning objects and degrees of dirt to achieve the best cleaning effect; in ultrasonic welding equipment, the welding parameters can be optimized and the welding quality improved by adjusting the length of the amplitude transformer for welding materials of different thicknesses and materials.
[0005] Based on this, this solution proposes a device for automatic calibration of ultrasonic amplitude transformers. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 This utility model provides a technical solution: an automatic calibration device for an ultrasonic amplitude transformer, comprising an ultrasonic device 1, a fixed column 3 fixedly installed on the top of the ultrasonic device 1, a connecting column 4 fixedly installed on the fixed column 3, an adjusting motor 16 fixedly installed on the top of the connecting column 4, and a connector 5 fixedly installed on the bottom of the connecting column 4. A connecting block 14 is fixedly connected to the bottom of the connector 5, an installation groove 20 is opened at the bottom of the connecting block 14, and three through holes are evenly spaced on the connecting block 14. A telescopic rod 21 is fixedly installed on the top inner wall of the installation groove 20, an ultrasonic amplitude transformer 7 is fixedly installed at the bottom end of the telescopic rod 21, a fixed rod 13 is fixedly installed on the ultrasonic amplitude transformer 7, a movable hole is opened on the connecting column 4, a vertical rod 9 is slidably installed in the movable hole, and connecting rods are fixedly installed at both ends of the vertical rod 9. The connecting rod 8 is connected to the positioning block 11. A positioning motor 12 is fixedly installed on one side of the positioning block 11, and two positioning screws 18 are rotatably installed inside the positioning block 11. Each of the two positioning screws 18 is threaded with an L-shaped movable rod 19, and the two positioning screws 18 are fixedly connected. An adjusting rack 17 is fixedly installed at the bottom of the connecting rod 8. An adjusting gear 15 that meshes with the adjusting rack 17 is fixedly sleeved on the output shaft of the adjusting motor 16. A first spring 10 is sleeved on the vertical rod 9. One end of the first spring 10 is fixed on the vertical rod 9, and the other end of the first spring 10 is fixed on the inner wall of the movable hole. The threads of the two positioning screws 18 are set in opposite directions. A slide rail is fixedly installed in the positioning block 11 along the horizontal direction. Two sliders are slidably installed on the slide rail, and the two sliders are fixedly connected to the corresponding L-shaped movable rods 19.
[0030] In this embodiment, when it is necessary to calibrate the vertical position of the ultrasonic amplitude transformer 7, the positioning motor 12 is started to drive the rotation of the two positioning screws 18, which in turn drives the two L-shaped movable rods 19 to move towards each other, thus fixing the rod 13 for clamping and fixing. The control panel 2 starts the adjustment motor 16, which meshes with the adjustment rack 17 at the bottom of the connecting rod 8 through the adjustment gear 15 on the output shaft, thereby driving the connecting rod 8 and the vertical rod 9 to move upward, which in turn drives the ultrasonic amplitude transformer 7 to move upward. The ultrasonic amplitude transformer 7 and the telescopic rod 21 form an amplitude transformer, thus adjusting the actual length of the amplitude transformer.
[0031] Combination Figure 1-5 As shown, in this embodiment, compression blocks 26 are fixedly installed on both sides of the ultrasonic amplitude transformer 7, and a crossbar 24 is slidably installed in any one of the through holes. Rollers 25 and pulling blocks 22 are fixedly installed at both ends of any one of the crossbars 24, and the two compression blocks 26 are symmetrically arranged. One end of any one of the second springs 23 is fixed on the corresponding crossbar 24, and the other end of any one of the second springs 23 is fixed on the inner wall of the corresponding through hole.
[0032] In this embodiment, as the ultrasonic amplitude transformer 7 moves upward, it drives the two compression blocks 26 to move upward. During the upward movement of the compression blocks 26, the rollers 25 are compressed twice, causing the corresponding two crossbars 24 to retract inward and the corresponding two second springs 23 to retract. When the compression blocks 26 move above the rollers 25, the crossbars 24 are ejected outward by the elastic force of the second springs 23, thus locking the height position of the compression blocks 26. After the adjustment is completed, the fixed rod 13 can be released by reversing the start of the output shaft of the positioning motor 12.
[0033] Combination Figure 1-5 As shown, in this embodiment, a laser displacement measuring device 6 is fixedly installed on the side of the ultrasonic device 1 near the ultrasonic amplitude transformer 7, and a control panel 2 is fixedly installed on the top of the ultrasonic device 1.
[0034] In this embodiment, the laser displacement measuring device 6 measures the displacement change of the ultrasonic amplitude transformer 7 in real time and feeds the data back to the control panel 2. The control panel 2 adjusts the working status of the motor 16 and the positioning motor 12 wirelessly according to the preset calibration parameters and real-time measurement data until the ultrasonic amplitude transformer 7 reaches the predetermined calibration position.
[0035] Working principle of this utility model:
[0036] The ultrasonic amplitude transformer 7 is installed in the mounting groove 20 of the connecting block 14 via the telescopic rod 21, ensuring that it can move vertically.
[0037] The control panel 2 on the ultrasonic device 1 is used to control the entire calibration process.
[0038] The laser displacement measuring device 6 is used to accurately measure the displacement change of the ultrasonic amplitude transformer 7.
[0039] Vertical calibration: When it is necessary to calibrate the vertical position of the ultrasonic amplitude transformer 7, firstly, the positioning motor 12 is started, which drives the two positioning screws 18 to rotate, thereby causing the two L-shaped movable rods 19 to move towards each other, thus fixing the rod 13 for clamping and fixation. The control panel 2 starts the adjustment motor 16, which meshes with the adjustment rack 17 at the bottom of the connecting rod 8 through the adjustment gear 15 on the output shaft, thereby driving the connecting rod 8 and the vertical rod 9 to move upward, thus driving the ultrasonic amplitude transformer 7 to move upward. The ultrasonic amplitude transformer 7 and the telescopic rod 21 form an amplitude transformer, which can be adjusted to the actual position. The ultrasonic amplitude transformer 7 moves upward, which drives the two extrusion blocks 26 to move upward. During the upward movement of the extrusion blocks 26, the rollers 25 are extruded twice, causing the corresponding two crossbars 24 to retract inward and the corresponding two second springs 23 to retract. When the extrusion blocks 26 move above the rollers 25, the crossbars 24 are ejected outward by the elastic force of the second springs 23, which can lock the height position of the extrusion blocks 26. After the adjustment is completed, the fixed rod 13 can be released by reversing the start of the output shaft of the positioning motor 12.
[0040] Measurement and feedback during calibration: The laser displacement measuring device 6 measures the displacement change of the ultrasonic amplitude transformer 7 in real time and feeds the data back to the control panel 2. The control panel 2 adjusts the working status of the motor 16 and the positioning motor 12 wirelessly according to the preset calibration parameters and real-time measurement data until the ultrasonic amplitude transformer 7 reaches the predetermined calibration position.
[0041] Based on the above working principle, this patented device for automatic calibration of ultrasonic amplitude transformers can automatically calibrate for materials of different thicknesses and materials by adjusting the actual length of the amplitude transformer, thereby improving the performance and working efficiency of ultrasonic equipment.
