The electrode placement plate 25 is connected to a controller 26 through wires. An ohmmeter 27 is arranged on the inner side of the conveying platform 3, and the ohmmeter 27 is connected to the electrode placement plate 25 through wires. When the conveying platform 3 enters the first chamber 16, the magnetic field generator 19 is started, and the magnetic field generator 19 creates a magnetic field environment for the ultrasonic transducer 24 on the conveying platform 3. Then the ohmmeter 27 detects the magnetic field through the electrode placement plate 25 and the controller 26. The resistance value under the current environment, then when the conveyor 3 drives the ultrasonic transducer 24 into the second chamber 17, the air heater 20 is started, and the air heater 20 heats the inside of the second chamber 17 to create a high temperature environment for the ultrasonic transducer 24.

After the detection is completed, the discharge pump 22 is started, and the discharge pump 22 discharges the liquid in the third chamber 18, which is convenient for the ultrasonic transducer 24 to be taken out, which is conducive to setting different environments to detect the ultrasonic transducer 24, and detecting the performance indicators of the ultrasonic transducer 24 in various environments, which is convenient for evaluating the quality of the ultrasonic transducer 24, reducing the use failure of the ultrasonic transducer 24, and detecting the ultrasonic transducer 24 in real time through the ohmmeter 27, which is convenient for quickly classifying and processing the ultrasonic transducer 24, and improving the efficiency of detection.

[0034] As an embodiment of the present invention, Figure 2 and Figure 3 as well as Figure 8As shown, the sealing protection mechanism includes a telescopic airbag 28 arranged between the side of the slider 4 and the inner wall of the slideway 5, the telescopic airbag 28 is fixedly connected to one end of a first air delivery pipe 29, the other end of the first air delivery pipe 29 passes through the conveying platform 3 and the slider 4 and is fixedly connected to a first expansion airbag 30, the first expansion airbag 30 is sleeved on the conveying platform 3, the inner side of the first expansion airbag 30 is fixedly connected to one end of a second air delivery pipe 31, the other end of the second air delivery pipe 31 passes through the conveying platform 3 and is fixedly connected to a second expansion airbag 32, and the second The expansion airbag 32 is sleeved on the outer side of the ultrasonic transducer 24. When the conveyor 3 drives the ultrasonic transducer 24 into the first chamber 16, the second chamber 17 and the third chamber 18, the slider 4 at the bottom of the conveyor 3 squeezes the telescopic airbag 28, and the gas in the telescopic airbag 28 enters the first expansion airbag 30 through the first gas pipe 29. Then the first expansion airbag 30 expands, and the first expansion airbag 30 seals the entrances of the first chamber 16, the second chamber 17 and the third chamber 18, so that the first chamber 16, The second chamber 17 and the third chamber 18 form a sealed environment, and the strength and recovery effect of the telescopic airbag 28 are improved by the return spring 33. Finally, the gas in the first expansion airbag 30 enters the second expansion airbag 32 through the liquid inlet pump 21. The second expansion airbag 32 fixes and isolates the lower part of the ultrasonic transducer 24 in the placement groove 23. The apertures of the two channels opened in the front slot 10 of the functional table 1 are larger than the inlet apertures of the first chamber 16, the second chamber 17 and the third chamber 18, so it does not affect the opening of the slot 10.

[0035] Working principle: When in use, first put the ultrasonic transducer 24 into the right conveying platform 3 in the slot 10, and the left conveying platform 3 is used to take out the ultrasonic transducer 24 that has been tested, then start the servo motor 7, the servo motor 7 drives the guide plate 8 to rotate counterclockwise, the guide channel 9 provided on the guide plate 8 guides the guide rod 6, and because the slider 4 at the bottom of the conveying platform 3 is restricted by the slideway 5, the conveying platform 3 cannot rotate, so that the conveying platform 3 at the bottom of the guide rod 6 moves toward the center of the functional platform 1, and then start the step Stepper motor 11 drives gear 12 to rotate. Gear 12 meshes with gear ring 13, and gear ring 13 is fixed at the bottom end of center disk 2. Therefore, stepper motor 11 drives center disk 2 to rotate a fixed angle through gear 12 and gear ring 13, and the friction between function table 1 and center disk 2 is reduced by rolling of ball 14 in guide groove 15. Finally, servo motor 7 drives guide disk 8 to rotate clockwise in the same way. Guide disk 8 drives conveying table 3 to enter different detection chambers in turn through guide rod 6 and servo motor 7.

[0036] When the conveyor 3 enters the first chamber 16, the magnetic field generator 19 is started, and the magnetic field generator 19 creates a magnetic field environment for the ultrasonic transducer 24 on the conveyor 3. Then the ohmmeter 27 detects the resistance value in the current environment through the electrode placement plate 25 and the controller 26. Then, when the conveyor 3 drives the ultrasonic transducer 24 to enter the second chamber 17, the air heater 20 is started, and the air heater 20 heats the inside of the second chamber 17 to create a high-temperature environment for the ultrasonic transducer 24. Finally, when the conveyor 3 drives the ohmmeter 27 to enter the third chamber 18, the liquid inlet pump 21 is started, and the liquid inlet pump 21 delivers liquid into the third chamber 18. The liquid can be the liquid that the ultrasonic transducer 24 contacts with in the use environment, or it can be replaced by water. After the detection is completed, the drainage pump 22 is started, and the drainage pump 22 removes the liquid in the third chamber 18 to facilitate the removal of the ultrasonic transducer 24.

[0037] When the conveying platform 3 drives the ultrasonic transducer 24 into the first chamber 16, the second chamber 17 and the third chamber 18, the slider 4 at the bottom of the conveying platform 3 squeezes the telescopic airbag 28, and the gas in the telescopic airbag 28 enters the first expansion airbag 30 through the first air pipe 29, and then the first expansion airbag 30 expands, and the first expansion airbag 30 seals the entrances of the first chamber 16, the second chamber 17 and the third chamber 18, so that the first chamber 16, the second chamber 17 and the third chamber 18 become a sealed environment, and finally the gas in the first expansion airbag 30 enters the second expansion airbag 32 through the liquid inlet pump 21, and the second expansion airbag 32 fixes and isolates the lower part of the ultrasonic transducer 24 in the placement groove 23, and the apertures of the two channels opened in the front end slot 10 of the functional platform 1 are larger than the apertures of the entrances of the first chamber 16, the second chamber 17 and the third chamber 18, so it does not affect the placement of the ultrasonic transducer 24 on the conveying platform 3 in the slot 10.
