Description

Technical Field

[0001] The present invention relates to the technical field of piezoelectric vibrator detection, and in particular to a piezoelectric vibrator detection device for an ultrasonic diagnostic instrument. Background Art

[0002] In ultrasonic diagnostic equipment, piezoelectric vibrators are one of the core components, and their performance directly affects the accuracy and reliability of diagnosis. Therefore, testing piezoelectric vibrators is an important part of ensuring the normal operation of ultrasonic diagnostic equipment. Among them, high-precision non-contact measurement equipment is a common device for testing piezoelectric vibrators. It uses a laser beam to illuminate the surface of the piezoelectric vibrator and accurately measures the amplitude and vibration characteristics of the vibrator by measuring the phase or frequency change of the reflected light. Laser vibrometers have the advantages of high measurement accuracy and fast response speed.

[0003] Patent CN117419797A discloses a laser vibrometer and a method for using the same, and relates to the technical field of laser vibrometers. The laser vibrometer includes a protective device, a vibrometer body, and an adjusting device. The protective device includes a protective shell and a sliding device, and the protective shell is arranged on the adjusting device. The sliding device is arranged inside the protective shell, and the vibrometer body is arranged on the sliding device. The side wall of the protective shell is provided with a through hole for use with the lens of the vibrometer body. By pushing the sliding device, the lens of the vibrometer body extends out of the protective shell through the through hole, thereby realizing detection of the target. When not in use, by pulling the sliding device, the lens of the vibrometer body is retracted into the protective shell, thereby realizing protection of the vibrometer body and the lens, and avoiding damage or destruction caused by collision. The angle of the laser vibrometer can be adjusted by an adjustment device, and the overall structure is more compact and occupies a smaller volume, which effectively improves the adaptability of the laser vibrometer. However, after the piezoelectric vibrator is detected, the detected piezoelectric vibrator needs to be classified and collected according to the detection results, which is cumbersome, time-consuming and labor-intensive, resulting in low detection efficiency.

[0008] The upper end shaft of the detection platform is connected with a material guide slide plate, and the lower end of the material guide slide plate is fixedly connected with an inclined block body and a straight block body, the thicker end of the inclined block body is fixedly connected with the straight block body, and the lower end of the inclined block body is slidably overlapped with a movable column, and the lower end of the movable column is fixedly connected with the inner wall of the detection platform.

[0009] Furthermore, the bottoms of the storage drawer A and the storage drawer B are both inclined surfaces, and the ends of the storage drawer A and the storage drawer B away from the testing platform are the lowest ends of the inclined surfaces.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to solve the technical problem that after the piezoelectric vibrators are tested, the tested piezoelectric vibrators need to be classified and collected according to their test results, which is cumbersome, time-consuming and labor-intensive, resulting in low detection efficiency, such as Figure 1-7 As shown, the following preferred technical solutions are provided:

[0034] A piezoelectric vibrator detection device for an ultrasonic diagnostic instrument comprises an outer frame 1, and an inner frame 2 slidably connected to the inner wall of the outer frame 1, a laser detection body 3 is installed on the top of the cavity of the inner frame 2, a detection platform 4 is slidably connected to the inner wall of the inner frame 2, a collection box assembly 5 is arranged at one end of the detection platform 4, a threaded rod 6 is threadedly connected to the inner wall of the inner frame 2, and the end of the threaded rod 6 away from the inner frame 2 is rotatably connected to the outer frame 1, and the inner frame 2 can be raised and lowered by connecting a motor to the threaded rod 6 to control the height of the detection platform 4, and the collection box assembly 5 comprises a box body 51 arranged at one end of the detection platform 4. The inner wall of the box body 51 is slidably connected with a storage drawer A52 and a storage drawer B53. A feeding port 54 is provided at one end of the storage drawer B53. The storage drawer A52 is used to store piezoelectric vibrators that meet the inspection standards, and the storage drawer B53 is used to store piezoelectric vibrators that do not meet the inspection standards. The upper end axis of the inspection table 4 is connected with a material guide slide plate 7. The lower end of the material guide slide plate 7 is fixedly connected with an inclined block body 8 and a straight block body 9. The end of the inclined block body 8 with a larger thickness is fixedly connected to the straight block body 9. The lower end of the inclined block body 8 is slidably overlapped with a movable column 10, and the lower end of the movable column 10 is fixedly connected to the inner wall of the inspection table 4.

[0035] The bottoms of storage drawer A52 and storage drawer B53 are both inclined surfaces, and the ends of storage drawer A52 and storage drawer B53 away from the inspection table 4 are the lowest ends of the inclined surfaces. When the movable column 10 abuts against the straight block body 9, the material guide slide 7 tilts upward, and the lowest point of the material guide slide 7 abuts against the storage drawer A52.

[0036] Specifically, when testing the piezoelectric vibrator, it is only necessary to place it on the material guide slide 7 on the upper wall of the testing platform 4, start the laser testing body 3, use the laser beam to irradiate the surface of the piezoelectric vibrator, and accurately measure the amplitude and vibration characteristics of the vibrator by measuring the phase or frequency change of the reflected light. After the test is completed, if the test result meets the standard, the threaded rod 6 is connected to the motor, and the motor drives the threaded rod 6 to rotate, driving the internal frame 2 and the testing platform 4 to move downward. When the testing platform 4 is moved to the position of the storage drawer A52, the testing platform 4 is pushed so that the testing platform 4 moves on the inner wall of the internal frame 2 and approaches the storage drawer A52. At this time, the inclined block body 8 will move on the movable column 10. When the movable column 10 abuts against the straight block body 9 , the material guide slide plate 7 is tilted upward, thereby driving the piezoelectric vibrators with qualified test results to be introduced into the storage drawer A52 for collection. If the test results are not up to standard, the internal rack 2 and the test table 4 are similarly driven to move downward. When the test table 4 is moved to the position of the storage drawer A52, the storage drawer A52 is then pulled outward to expose the feed port 54. At this time, the test table 4 is pushed, and the piezoelectric vibrators with unqualified test results are introduced into the storage drawer B53 through the feed port 54 for collection. Therefore, the classification and collection operation is extremely convenient, which solves the problem that after the piezoelectric vibrators are tested, the tested piezoelectric vibrators need to be classified and collected according to their test results. The operation is cumbersome, time-consuming and labor-intensive, resulting in low detection efficiency.

[0037] The outer wall of the threaded rod 6 is fixedly connected with a driving gear 11, one side of the driving gear 11 is meshedly connected with a driven gear 12, the inner wall of the driven gear 12 is provided with a side push assembly 13, the side push assembly 13 is used to push the detection platform 4, the side push assembly 13 includes an external rod 131 fixedly connected to the inner wall of the driven gear 12, the lower end of the external rod 131 is rotatably connected to the bottom plate of the external frame 1, the inner wall of the external rod 131 is slidably connected with an internal rod 132, the upper end of the internal rod 132 is provided with a mounting groove 133 opened on the lower wall of the detection platform 4, the two side walls of the mounting groove 133 are respectively fixedly connected with a first tooth group 134 and a second tooth group 135, and the first tooth group 134 and the second tooth group 135 are symmetrically distributed about the center of the mounting groove 133.

[0038] The upper end of the inner connecting rod 132 is fixedly connected with a side thrust gear 136, which is meshedly connected with the first tooth group 134 and the second tooth group 135. The side thrust gear 136 is only provided with meshing teeth on half of the outer wall. When the side thrust gear 136 is meshedly connected with the first tooth group 134 and continuously rotates, it will drive the detection platform 4 away from the storage drawer A52. When the side thrust gear 136 is meshedly connected with the second tooth group 135 and continuously rotates, it will drive the detection platform 4 close to the storage drawer A52.

[0039] Specifically, when the motor drives the threaded rod 6 to rotate, the threaded rod 6 will drive the driving gear 11 to rotate, and the driving gear 11 will drive the driven gear 12 to rotate, thereby driving the outer rod 131 and the inner rod 132 to rotate through the driven gear 12, and the inner rod 132 will drive the side thrust gear 136 at the same time, and the side thrust gear 136 will be driven to engage with the second tooth group 135, and the side thrust gear 136 will continue to rotate, which will drive the detection platform 4 to approach the storage drawer A52, thereby lowering the detection platform 4 to the storage drawer A52, and the detection platform 4 will be laterally close to the storage drawer A52 at the same time, which further provides convenience for the staff and has a significant effect.

[0040] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, a method for implementing a piezoelectric vibrator detection device for an ultrasonic diagnostic instrument, comprising the following steps:

[0041] Step 1: Place the piezoelectric vibrator to be tested on the material guide slide 7 on the upper wall of the testing table 4, start the laser testing body 3, irradiate the surface of the piezoelectric vibrator with a laser beam, and accurately measure the amplitude and vibration characteristics of the vibrator by measuring the phase or frequency change of the reflected light;

[0042] Step 2: When the test result meets the standard, the motor is connected to the threaded rod 6, and the motor drives the threaded rod 6 to rotate, and drives the internal frame 2 and the test platform 4 to move downward, and moves the test platform 4 to the position of the storage drawer A52. When the motor drives the threaded rod 6 to rotate, the threaded rod 6 will drive the driving gear 11 to rotate, and the driving gear 11 drives the driven gear 12 to rotate, thereby driving the outer rod 131 and the inner rod 132 to rotate through the driven gear 12, and the inner rod 132 drives the side push gear 136 at the same time, and the side push gear 136 will be driven to mesh with the second gear set 135, and the side push gear 136 will continue to rotate, which will drive the test platform 4 close to the storage drawer A52, and the inclined block body 8 will move on the movable column 10. When the movable column 10 abuts against the straight block body 9, the guide slide plate 7 tilts upward, thereby driving the piezoelectric vibrator with the test result meeting the standard to be introduced into the storage drawer A52 for collection;

[0043] Step three: If the test results do not meet the standards, the internal frame 2 and the test table 4 will be moved downward. When the test table 4 is moved to the position of the storage drawer A52, the storage drawer A52 is then pulled out to expose the feed port 54. At this time, the piezoelectric vibrators with unsatisfactory test results are introduced into the storage drawer B53 through the feed port 54 for collection.
