Description

Technical Field

[0001] The present invention relates to the technical field of transducer temperature resistance detection, and in particular to an ultrasonic transducer temperature resistance detection device and method. Background Art

[0002] Ultrasonic transducers are devices that use the piezoelectric effect of ceramics to convert the mechanical vibrations generated by ultrasound into electrical signals or generate mechanical vibrations under the drive of an electric field to emit ultrasound. In detection applications, ultrasonic transducers are used in pairs, one for transmission and the other for reception. In order to ensure the validity of the ultrasonic transducer detection data, it is necessary to ensure that the characteristics of the transmission wave and the echo of the paired transducers match.

[0003] In order to ensure the effectiveness of ultrasonic transducers under extreme temperatures, it is usually necessary to perform temperature resistance tests on ultrasonic transducers. When existing ultrasonic transducer temperature resistance testing equipment is used to test the transducer, the transducer is usually fixed. However, when the transducer is used in a high temperature environment, it may be used with vibration. If the transducer is not subjected to a vibration test at high temperature, the performance of the transducer in a high temperature vibration environment cannot be obtained. In addition, after the existing temperature resistance testing equipment has performed a high temperature test on the transducer, the physical properties of the piezoelectric ceramics, metals and other materials inside the transducer may produce stress or residual stress due to the high temperature. The existing temperature resistance testing equipment does not have a cooling function and can only rely on natural cooling. Due to the slow natural cooling speed, the natural cooling process will not be effective. During the cooling process, these stresses may not be fully released, causing problems such as structural loosening, deformation or damage. In particular, when preload is used during the transducer assembly process, natural cooling may lead to preload loss, which in turn affects the performance and stability of the transducer after the test. After the high-temperature test of the ultrasonic transducer is completed, the performance parameters of the transducer, such as resonant frequency and amplitude, may change. In order to ensure the accuracy of the temperature resistance test, it is necessary to wait for the transducer to cool to room temperature and retest its performance parameters to evaluate its performance stability in a high temperature environment. The existing temperature resistance test equipment lacks a cooling device, so subsequent testing or evaluation work needs to wait for the transducer to cool naturally, which will extend the entire test cycle and reduce detection efficiency.

[0021] In this embodiment, when using, the operator can first insert the transducer 15 to be monitored into the clamping table 13, and the transducer 15 is installed and fixed by the mounting plate inside the clamping table 13.

A cooling water pipe 30, a cleaning agent pipe 29 and a hot water pipe 28 are arranged inside the infusion rod 35. The cooling water pipe 30 is connected to the interior of the cold water cavity 40.

The interior of the hot water pipe 28 is connected to a hot water delivery port 58, and the hot water delivery port 58 is located inside the hot water cavity 42, and a liquid storage tank 23 is fixedly connected to the outer wall of the mounting platform 22. A water storage tank 25, a detergent storage tank 26 and a hot water tank 27 are respectively arranged inside the liquid storage tank 23. A heater is arranged inside the hot water tank 27. The cooling water pipe 30, the detergent pipe 29 and the hot water pipe 28 are connected to the inside of the water storage tank 25, the detergent storage tank 26 and the hot water tank 27 at one end away from the infusion rod 35. The inside of the water storage tank 25, the detergent storage tank 26 and the hot water tank 27 are all provided with a pluggable liquid filling port 24, and the inside of the cooling cylinder 36 is provided with a cleaning brush 14.

[0023] In this embodiment, after the device body 1 completes the temperature resistance test on the transducer 15, in order to ensure the use effect of the transducer 15 after the test, the multiple driving wheels 7 in the side rails 6 will rotate, allowing the test bench 8 to move out of the device body 1 along the side rails 6. When the test bench 8 drives the transducer 15 to move to the bottom of the cooling cylinder 36, the driving wheel 7 will stop rotating, allowing the transducer 15 to stay under the cooling cylinder 36. When the transducer 15 stays under the cooling cylinder 36, the telescopic rod 21 starts and contracts, and the cooling cylinder 36 is put on the outside of the transducer 15. When the transducer 15 is located under the cooling cylinder 36, the telescopic rod 21 starts and contracts. After the transducer 15 is inside the cylinder 36, in the initial stage of cooling the transducer 15, in order to avoid the cooling speed being too fast, resulting in rapid cooling of the transducer 15 and affecting the physical properties of the internal material thereof, the speed regulating motor 31 will be started at low power, and the transmission rod 34 will be driven to rotate slowly through the rotating wheel 32 and the belt 33. When the transmission rod 34 rotates slowly, under the action of a small centrifugal force, the baffle 44 will overcome the tension of the tension spring 45 and move a short distance to the outside of the water delivery box 37. When the baffle 44 moves a short distance to the outside of the water delivery box 37, one of the two through holes 54 will come to the right side of the baffle 44 (refer to Fig.10), when one of the two through holes 54 comes to the right side of the baffle 44, the baffle 44 will no longer block it. When the transmission rod 34 rotates, the cold water in the cold water chamber 40 will be thrown into the water delivery box 37. When the baffle 44 no longer blocks one of the two through holes 54, the cooling water entering the water delivery box 37 will enter the circulation box 46 through the single through hole 54, and then enter the bottom box 39 through the infusion channel 38. When the transmission rod 34 rotates slowly, it will also drive the bottom box 39 to rotate slowly. When the bottom box 39 rotates slowly, the hot water in the hot water chamber 42 will be thrown into the hot water channel 49. Since the rotation speed of the bottom box 39 is slow, the hot water produced at this time The generated smaller centrifugal force will cause the trigger member 55 to overcome the elastic force of the pressing spring 53 and move a short distance to the outside of the bottom box 39. When the trigger member 55 moves a short distance to the outside of the bottom box 39, it will push the flow regulating plate 56 a short distance into the hot water channel 49 along its inclined surface, thereby blocking the hot water passing through the hot water channel 49 in a small range. The hot water entering the hot water channel 49 will finally flow to the outside of the bottom box 39 through the ejection hole 60 in large quantities and mix with the cold water transported from the infusion channel 38. After the cold water and hot water are mixed in the bottom box 39 to form warm water, they will enter the cooling cylinder 36 through the liquid guide tube 43 to cool the transducer 15 located inside the cooling cylinder 36.

[0024] When the warm water cools the transducer 15 for a period of time, in the middle of the cooling process, the speed regulating motor 31 will drive the wheel 32 to rotate at a medium power. Under the above principle, the transmission rod 34 will rotate rapidly compared with the initial stage of cooling. When the transmission rod 34 rotates rapidly, under the action of a large centrifugal force, the baffle 44 will overcome the tension of the tension spring 45 and move a large distance to the outside of the water delivery tank 37. When the baffle 44 moves a greater distance to the outside of the water delivery tank 37, the two through holes 54 will be located on the right side of the baffle 44 (refer to Fig.10), when the two through holes 54 come to the right side of the baffle 44, the baffle 44 will no longer block it. At this time, the cooling water entering the water delivery box 37 will enter the circulation box 46 through the two through holes 54, and then flow into the bottom box 39 through the infusion channel 38. The cold water is input through the two through holes 54. Compared with the initial stage of cooling, the amount of cold water input into the bottom box 39 by the water delivery box 37 will increase. When the transmission rod 34 drives the bottom box 39 to rotate rapidly, the larger centrifugal force generated at this time will cause the trigger member 55 to overcome the elastic force of the pressing spring 53 and move a greater distance to the outside of the bottom box 39. When the trigger member 55 moves a greater distance to the outside of the bottom box 39, it will flow along its inclined surface. The regulating plate 56 is pushed further into the hot water channel 49. When the flow regulating plate 56 moves further into the hot water channel 49, the blocking effect of the flow regulating plate 56 on the hot water in the hot water channel 49 will be improved compared with before. Therefore, the amount of hot water flowing from the hot water channel 49 to the outside of the bottom tank 39 through the liquid ejection hole 60 will be reduced. When the amount of cold water delivered to the bottom tank 39 by the water delivery tank 37 through the liquid delivery channel 38 increases, and the amount of hot water delivered by the hot water channel 49 decreases, when the two are mixed, the temperature of the warm water mixed in the middle of the cooling process is lower than that in the initial stage of cooling. After the warm water with a lower temperature is mixed in the bottom tank 39, it will enter the cooling cylinder 36 through the liquid guide tube 43 again to drip and cool the transducer 15. When the lower temperature warm water cools the transducer 15 for a period of time, in the late stage of cooling, the speed regulating motor 31 will drive the wheel 32 to rotate at a high power. When the wheel 32 rotates at a high speed, the amount of cold water input from the water delivery box 37 to the bottom box 39 through the infusion channel 38 remains unchanged. Compared with the middle stage of cooling, a greater centrifugal force will be generated, which will cause the trigger member 55 to overcome the elastic force of the pressing spring 53 and move a greater distance to the outside of the bottom box 39. When the trigger member 55 moves a long distance to the outside of the bottom box 39, the trigger member 5 5 will make its plane contact with the flow regulating plate 56, thereby pushing the flow regulating plate 56 to completely block the hot water channel 49, so that the hot water channel 49 no longer transmits hot water to the outside of the bottom box 39 through the liquid ejection hole 60. When the trigger member 55 moves to a relatively far distance outside the bottom box 39, the flow regulating plate 56 completely blocks the hot water channel 49, and at the same time, it will drive the push plate 48 to contact and push the slide tube 50. When the push plate 48 pushes the slide tube 50 to move into the infusion channel 38, the drip hole 52 will enter the cleaning channel. When the dripping hole 52 enters the cleaning channel 47, the cleaning liquid transported in the cleaning channel 47 will enter the slide tube 50 through the dripping hole 52, and then enter the infusion channel 38 through the open end of the slide tube 50 to mix with the cooling water transported by the infusion channel 38. When the hot water channel 49 stops transporting hot water, the cooling water mixed with the cleaning liquid enters the bottom box 39, and then enters the transducer 15 through the liquid guide tube 43 to drip on the transducer 15. The temperature of the water is lower than the temperature of the warm water in the middle of the cooling process. By using cooling water of different temperatures to cool the transducer 15 in stages, it is possible to avoid the phenomenon that rapid cooling causes the material inside the transducer 15 to have an excessively large thermal gradient, thereby affecting the physical properties of the entire transducer 15. After the cooling water mixed with the cleaning liquid enters the cooling cylinder 36, it can also cooperate with the rotating multiple cleaning brushes 14 to clean the impurities generated by thermal decomposition on the surface of the transducer 15, thereby avoiding impurities remaining on the transducer 15 and affecting subsequent detection.

[0025] It should be noted that in the later stage of cooling, when the transmission rod 34 rotates at high speed, although the baffle 44 will overcome the tension of the tension spring 45 and be thrown to the outside of the water tank 37, there are only two through holes 54 in the water tank 37. Therefore, the water flow rate does not change compared with the middle stage of cooling.

[0026] It should also be noted that, in the later stage of cooling, after the cooling water mixed with cleaning liquid has cooled and cleaned the transducer 15, the speed regulating motor 31 will drive the transmission rod 34 to slowly slow down until it stops. When the transmission rod 34 slowly rotates until it stops, the effect of the transmission rod 34 caused by the rotation speed will also be realized under the action of the above principle. At this time, the bottom box 39 will re-introduce warm water into the cooling cylinder 36, and cooperate with the cleaning brush 14 to brush the surface of the transducer 15 to avoid residual cleaning liquid on the surface of the transducer 15, which affects the use of the transducer 15. Since the process of slowly slowing down the transmission rod 34 until it stops is relatively short, the warm water will not reheat the transducer 15. At the same time, the adjustment of the driving power of the speed regulating motor 31 and the test bench 8 driving the transducer 15 to move to the position directly below the cooling cylinder 36 and stop are all controlled by PLC programming (this is the prior art and will not be elaborated in detail).

[0027] It should also be noted that when the transmission rod 34 rotates, the infusion rod 35 is stationary relative to the transmission rod 34. Therefore, the cooling water pipe 30 in the infusion rod 35 will transport the cold water in the water storage tank 25 to the cold water cavity 40 through the cold water dripping port 62, the detergent pipe 29 will transport the cleaning liquid in the detergent storage tank 26 to the cleaning cavity 41 through the cleaning liquid dripping port 63, and the hot water pipe 28 will transport the hot water in the hot water tank 27 to the hot water cavity 42 through the hot water delivery port 58. The hot water tank 27 is provided with a heater to heat the cooling water in the hot water tank 27. The cooling water used by the cooling cylinder 36 to cool the transducer 15 will drip into the water receiving tank 5 for collection.

[0028] It should also be noted that a cover 59 is provided on the outside of the ejection hole 60 to block it. Only when the bottom box 39 rotates, under the action of centrifugal force, the cover 59 will overcome the elastic force of the pressure spring and move, thus losing the blockage of the ejection hole 60.
