[0049] See also Figure 1 and Figure 2 As shown, the ultrasonic probe acoustic testing device according to the embodiment of the utility model comprises a test frame 100, a probe fixing frame 200 and a three-way displacement adjustment mechanism 300. The test frame 100 is provided with a reflection plate 110 for reflecting signals. The probe fixing frame 200 is used to fix and install the ultrasonic probe 10. The three-way displacement adjustment mechanism 300 is used to be fixed to the test frame 100.

[0050] The three-way displacement adjustment mechanism 300 includes a first linear displacement mechanism 310, a second linear displacement mechanism 320 and an angular displacement mechanism 330. The first linear displacement mechanism 310 is fixedly mounted on the test frame 100 along the X-axis, the second linear displacement mechanism 320 is movably arranged on the first linear displacement mechanism 310, and the second linear displacement mechanism 320 is extended along the Z-axis, the angular displacement mechanism 330 is movably arranged on the second linear displacement mechanism 320, the probe fixing frame 200 is fixed to the angular displacement mechanism 330, and the axial direction of the ultrasonic probe 10 is arranged along the Z-axis, and the probe fixing frame 200 can swing around the Y-axis under the action of the angular displacement mechanism 330.

[0051] The three-way displacement adjustment mechanism 300 is used to adjust the displacement of the ultrasound probe 10 on the X-axis and Z-axis, and the swing angle around the Y-axis, so that the signal emitting surface 101 of the ultrasound probe 10 can be parallel to the signal reflecting surface 111 of the reflecting plate 110 .

[0052] The ultrasonic probe acoustic test device of the embodiment of the utility model comprises a test frame 100, a probe fixing frame 200 and a three-way displacement adjustment mechanism 300. The probe fixing frame 200 is used to fix and install the ultrasonic probe 10, and fix the ultrasonic probe 10 to the three-way displacement adjustment mechanism 300. The three-way displacement adjustment mechanism 300 can adjust the displacement of the ultrasonic probe 10 on the X-axis and the Z-axis, and the swing angle around the Y-axis, so that the signal emitting surface 101 of the ultrasonic probe 10 can be parallel to the signal reflecting surface 111 of the reflecting plate 110. Therefore, the ultrasonic probe acoustic test device of the embodiment of the utility model can realize automatic adjustment of the position and angle of the ultrasonic probe 10, and only the displacement of the ultrasonic probe 10 on the X-axis and the Z-axis, and the swing angle around the Y-axis need to be adjusted. The adjustment process takes a short time, thereby effectively improving the adjustment efficiency and the test efficiency.

[0053] The test frame 100 is mainly used to carry and set the relevant structural components of the ultrasonic probe acoustic test. The test frame 100 can be made of aluminum profiles or steel materials to ensure its structural stability. The test frame 100 can have a roughly rectangular frame body.

[0054] like Figure 1 As shown, in one embodiment, a water tank 120 is fixedly mounted on the test stand 100, and the water tank 120 is a structure with an open top, and the reflector 110 is arranged at the bottom of the water tank 120. The water tank 120 can contain water as a propagation medium. Compared with directly performing acoustic testing without using water as a propagation medium, this embodiment enables ultrasonic signals to propagate in water by setting up the water tank 120 to simulate the propagation of ultrasonic waves in human tissues, thereby improving the test accuracy. At the same time, by allowing ultrasonic signals to propagate in water, the propagation speed of ultrasonic waves emitted by the ultrasonic probe 10 can be increased, thereby improving the test efficiency.

[0055] In this embodiment, since the density of water is close to that of the human body, the propagation of ultrasound in water and in human tissue is similar. Therefore, using water as a propagation medium for acoustic testing can effectively simulate the propagation of ultrasound in human tissue and improve the accuracy of the test. However, the present application is not limited to this, and in other embodiments, other propagation media may also be used, depending on the specific situation.

[0056] In this embodiment, the three-way displacement adjustment mechanism 300 can be fixed to the test frame 100 and is located on one side of the top opening of the water tank 120. The probe fixing frame 200 can be extended into the water tank 120 through the three-way displacement adjustment mechanism 300, and the signal emitting surface 101 of the ultrasonic probe 10 is parallel to the signal reflecting surface 111 of the reflecting plate 110 under the adjustment of the three-way displacement adjustment mechanism 300.

[0057] Combination Figure 3 As shown, the reflective plate 110 may be arranged to extend along the X-axis direction. The signal reflecting surface 111 of the reflective plate 110 may face the vertically upward direction.

[0058] During the test, the three-way displacement adjustment mechanism 300 is fixed to the test frame 100, so that the front end of the ultrasonic probe 10 on the probe fixing frame 200 is immersed in the water. It can be understood that for the sake of convenience of description, the ultrasonic transmitting end of the ultrasonic probe 10 is called the front end, and the end of the ultrasonic probe 10 opposite to the front end is the tail end.

[0059] When the front end of the ultrasonic probe 10 is immersed in water, the signal emitting surface 101 of the ultrasonic probe 10 faces the vertical downward direction. That is, the signal emitting surface 101 of the ultrasonic probe 10 is arranged opposite to the signal reflecting surface 111 of the reflecting plate 110. At this time, the position and angle of the ultrasonic probe 10 can be adjusted by the three-way displacement adjustment mechanism 300 so that the signal emitting surface 101 can be parallel to the signal reflecting surface 111 of the reflecting plate 110 at the bottom of the water tank 120. Figure 4 As shown, specifically, during the process of adjusting the position and angle of the ultrasonic probe 10, it is possible to determine whether the signal emitting surface 101 is parallel to the signal reflecting surface 111 by transmitting signals and receiving reflected signals. When the shortest distance between the signal emitting surface 101 and the signal reflecting surface 111 is equal at any position, that is, both are H, it means that the two are parallel to each other, and the ultrasonic probe 10 can be acoustically tested at this time.

[0060] In the embodiment of the present application, the three-way displacement adjustment mechanism 300 includes a first linear displacement mechanism 310. Figure 1 and Figure 2 As shown, in one embodiment, the first linear displacement mechanism 310 includes a first linear slide 311 and a first slide 312. The first linear slide 311 is fixedly mounted on the test frame 100 along the X-axis. The first slide 312 is slidably connected to the first linear slide 311. The second linear displacement mechanism 320 is fixedly mounted on the first slide 312. The first linear slide 311 can be fixedly mounted on the test frame 100 by using various structures capable of realizing detachable fixed connection, such as a threaded locking structure, a snap-fit ​​structure, and the like.

[0061] In the embodiment of the present application, the three-way displacement adjustment mechanism 300 further includes a second linear displacement mechanism 320. Figure 2 As shown, in one embodiment, the second linear displacement mechanism 320 includes a second linear slide 321 and a second slide 322, the second linear slide 321 is fixedly mounted on the first slide 312 along the Z axis, the second slide 322 is slidably connected to the second linear slide 321, and the angle displacement mechanism 330 is fixedly mounted on the second slide 322. Among them, the second linear slide 321 can be fixedly mounted on the first slide 312 using various structures that can achieve detachable fixed connection, such as a threaded locking structure, a snap-fit ​​structure, and the like.

[0062] In the embodiment of the present application, the three-way displacement adjustment mechanism 300 further includes an angle displacement mechanism 330. Figure 2As shown, in one embodiment, the angle displacement mechanism 330 includes a base 331 and a swing table 332, the base 331 is fixedly mounted on the second slide 322, the swing table 332 is rotatably arranged on the base 331, the probe fixing frame 200 is fixedly mounted on the swing table 332, and the swing table 332 can drive the probe fixing frame 200 to swing around the Y axis. The base 331 can be arranged perpendicular to the Z axis direction. For example, the base 331 can be fixedly connected to the second slide 322 through an L-shaped plate.

[0063] Among them, the base 331 and the L-shaped plate, as well as the L-shaped plate and the second slide 322, can be relatively fixed by adopting various structures capable of realizing detachable fixed connection, such as a threaded locking structure, a snap-fit ​​structure, etc.

[0064] See also Figure 2 As shown, in one embodiment, the three-way displacement adjustment mechanism 300 further includes a first driving member 340, a second driving member 350 and a third driving member 360. The first driving member 340 is in transmission connection with the first slide 312 to drive the first slide 312 to slide on the first linear slide rail 311. The first driving member 340 can be a stepping motor or a servo motor. The first driving member 340 can use a screw transmission structure or a gear rack transmission structure to drive the first slide 312 to slide.

[0065] The second driving member 350 is in driving connection with the second slide 322, and is used to drive the second slide 322 to slide on the second linear slide rail 321. The second driving member 350 can be a stepping motor or a servo motor. The second driving member 350 can use a screw transmission structure or a gear rack transmission structure to drive the second slide 322 to slide.

[0066] The third driving member 360 is connected to the swing table 332 for driving the swing table 332 to rotate on the base 331. The third driving member 360 can be a stepping motor or a servo motor. The third driving member 360 can be a worm gear structure to drive the swing table 332 to rotate.

[0067] In the embodiment of the present application, the first slide 312, the second slide 322 and the swing table 332 are driven by the first driving member 340, the second driving member 350 and the third driving member 360 respectively to adjust the position and angle of the ultrasound probe 10. However, the present application is not limited thereto, and in other embodiments, the movement of the first slide 312, the second slide 322 and the swing table 332 can also be achieved manually.

[0068] In the embodiment of the present application, the first linear displacement mechanism 310 can be fixedly mounted on the test frame 100 by a screw structure, and its first slide 312 can slide on the first linear slide rail 311 along the X axis. The second linear displacement mechanism 320 can be fixedly mounted on the first slide 312 of the first linear displacement mechanism 310 by a screw structure, and the second slide 322 of the second linear displacement mechanism 320 can slide on the second linear slide rail 321 along the Z axis. The angular displacement mechanism 330 can be fixedly mounted on the second slide 322 of the second linear displacement mechanism 320 by a screw structure, and the swing table 332 of the angular displacement mechanism 330 can swing around the Y axis. Since the ultrasonic probe 10 is fixed on the swing table 332 of the angular displacement mechanism 330, the displacement of the ultrasonic probe 10 on the X axis and the Z axis, as well as the swing angle around the Y axis, can be adjusted by the three-way displacement adjustment mechanism 300, so that the signal emitting surface 101 of the ultrasonic probe 10 can be parallel to the signal reflecting surface 111 of the reflecting plate 110.

[0069] In an embodiment of the present application, the first linear displacement mechanism 310 and the second linear displacement mechanism 320 may adopt a linear displacement table. The angular displacement mechanism 330 may adopt an angular displacement table. By using a displacement table device, precise control of the position and angle of the ultrasonic probe 10 can be achieved, thereby improving the test accuracy. However, the present application is not limited thereto. In other embodiments, the first linear displacement mechanism 310 may be a simple slide rail and slider matching structure, as long as it can achieve the displacement of the ultrasonic probe 10 on the X-axis. The second linear displacement mechanism 320 may also be a simple slide rail and slider matching structure, as long as it can achieve the displacement of the ultrasonic probe 10 on the Z-axis. The angular displacement mechanism 330 may include a rotating motor, and the purpose of driving the ultrasonic probe 10 to swing around the Y-axis can be achieved by the rotating motor.

[0070] In the embodiment of the present application, the probe fixing frame 200 is used to fix and install the ultrasound probe 10. Figure 3 In one embodiment, the probe fixing frame 200 includes a first fixing plate 210, a second fixing plate 220, and a connecting rod 230. The first fixing plate 210 and the second fixing plate 220 are arranged in parallel and spaced apart, and both ends of the connecting rod 230 are respectively connected to the first fixing plate 210 and the second fixing plate 220. The first fixing plate 210 is provided with a first clamping groove 211 for clamping the front end of the ultrasonic probe 10, and the second fixing plate 220 is provided with a second clamping groove 221 for clamping the rear end of the ultrasonic probe 10.

[0071] like Figure 3 As shown, the first fixing plate 210 may be a rectangular plate. A first slot 211 for clamping the front end of the ultrasonic probe 10 may be provided in the middle of the first fixing plate 210. The first slot 211 may be a stepped slot with a larger size at the bottom and a smaller size at the bottom along the Z-axis direction. The first slot 211 may limit and fix the ultrasonic probe 10 along the Z-axis direction.

[0072] like Figure 3 As shown, the second fixing plate 220 may be a rectangular plate. The second fixing plate 220 is provided with a second slot 221 for inserting the tail end of the ultrasonic probe 10. The second slot 221 may be an open slot provided on one side of the second fixing plate 220. The second slot 221 facilitates the fixed installation of the ultrasonic probe 10.

[0073] There may be more than one connecting rod 230 . For example, when the first fixing plate 210 is a rectangular plate, there may be four connecting rods 230 . The four connecting rods 230 are respectively arranged at four corners of the first fixing plate 210 .

[0074] In this embodiment, when the ultrasonic probe 10 is fixedly mounted on the probe fixing frame 200, the degrees of freedom of the ultrasonic probe 10 in all directions are restricted. When the probe fixing frame 200 is fixedly mounted on the three-way displacement adjustment mechanism 300, the ultrasonic probe 10 can only change its displacement on the X-axis and Z-axis, and the swing angle around the Y-axis through the three-way displacement adjustment mechanism 300. During the adjustment process, it is only necessary to drive the probe fixing frame 200 and the ultrasonic probe 10 thereon to displace along the X-axis and Z-axis, and swing around the Y-axis through the three-way displacement adjustment mechanism 300, without the need to make unnecessary adjustments to the position and angle of the ultrasonic probe 10 in other directions. This effectively reduces the steps of parallel alignment of the signal emitting surface 101 of the ultrasonic probe 10 and the signal reflecting surface 111 of the reflecting plate 110, thereby improving the adjustment efficiency.

[0075] The first fixing plate 210 and the connecting rod 230 may be relatively fixedly connected. For example, the first fixing plate 210 may be provided with a mounting hole, and the end of the connecting rod 230 may be inserted into the mounting hole and fixed to the first fixing plate 210 .

[0076] The second fixing plate 220 and the connecting rod 230 may be slidably connected. For example, a through hole may be provided on the second fixing plate 220, and the end of the connecting rod 230 away from the first fixing plate 210 is inserted into the through hole. The second fixing plate 220 can slide along the connecting rod 230. Thus, the distance between the second fixing plate 220 and the first fixing plate 210 can be changed as needed, so that the probe fixing frame 200 can fix ultrasonic probes 10 of different lengths, thereby improving the practicality and versatility of the testing device.

[0077] See also Figure 3In one embodiment, the probe fixing frame 200 further includes a pressing spring 240, which is sleeved on one end of the connecting rod 230, and is held between the end of the connecting rod 230 and the second fixing plate 220, so as to provide an elastic force for pressing the second fixing plate 220 toward the first fixing plate 210. By providing the pressing spring 240, when the ultrasonic probe 10 is fixed on the first fixing plate 210 and the second fixing plate 220, the second fixing plate 220 always has a tendency to move toward the first fixing plate 210 under the action of the pressing spring 240, so that the second fixing plate 220 can press and limit the ultrasonic probe 10 on the first fixing plate 210, thereby ensuring reliable fixation of the ultrasonic probe 10.

[0078] In other embodiments, the first fixing plate 210 and the second fixing plate 220 may both be fixedly connected to the connecting rod 230. The connecting rod 230 may be a retractable structure.

[0079] See also Figure 3 In one embodiment, the ultrasonic probe acoustic testing device further includes a connecting bracket 400, and the probe fixing frame 200 is fixed to the angle displacement mechanism 330 via the connecting bracket 400. Specifically, the probe fixing frame 200 is fixed to the swing table 332 of the angle displacement mechanism 330 via the connecting bracket 400.

[0080] like Figure 3 As shown, the connecting bracket 400 includes a first plate body 410, a second plate body 420 and a third plate body 430 connected to each other. The first plate body 410 is used to be fixedly connected to the angle displacement mechanism 330. The first plate body 410 can be arranged perpendicular to the Z axis.

[0081] The second plate body 420 is vertically connected to one end of the first plate body 410. Specifically, the second plate body 420 is arranged parallel to the Z axis.

[0082] The third plate 430 is vertically connected to one end of the second plate 420 away from the first plate 410, and is used to fix the probe fixing frame 200. The third plate 430 is arranged perpendicular to the Z axis. The first plate 410 and the third plate 430 are respectively located on both sides of the second plate 420.

[0083] like Figure 3 As shown, in one embodiment, a limiting groove 431 is provided on the third plate 430, and the probe fixing frame 200 is fixed in the limiting groove 431. The limiting groove 431 may be a stepped groove with a larger size at the bottom and a smaller size at the bottom along the Z-axis direction. The limiting groove 431 may limit and fix the probe fixing frame 200 along the Z-axis direction.

[0084] It should be noted that the ultrasonic probe acoustic testing device of the embodiment of the utility model may also include an adjustment control system. The adjustment control system is connected to the three-way displacement adjustment mechanism 300 and is used to control the action of each driving member according to the displacement feedback of each displacement stage device. Specifically, the adjustment control system can control the action of the first driving member 340, the second driving member 350 and the third driving member 360 to achieve precise adjustment of the position and angle of the ultrasonic probe 10.

[0085] In addition, the ultrasonic probe 10 to be tested can be connected to an acoustic test transmitting and receiving system. The acoustic test transmitting and receiving system is used to control the ultrasonic probe 10 to transmit ultrasonic signals and to control the ultrasonic probe 10 to receive ultrasonic signals reflected by the reflector 110.

[0086] At the same time, the acoustic test transmitting and receiving system can be configured with a test switching and storage module. The test switching and storage module is used to realize the switching of ultrasonic signals during the test process, as well as data storage and other functions.

[0087] See also Figures 1 to 3 When the ultrasonic probe acoustic testing device of the embodiment of the utility model is used:

[0088] First, a mounting groove for the reflector plate 110 may be provided at the bottom of the water tank 120, and the reflector plate 110 may be fixed to the mounting groove at the bottom of the water tank 120. An appropriate amount of water is filled in the water tank 120.

[0089] The water tank 120 is placed on the test frame 100. The test frame 100 may be provided with a limit stop bar 130, which is used to keep the water tank 120 stably installed.

[0090] The ultrasonic probe 10 to be tested is fixed by the probe fixing frame 200, and then the probe fixing frame 200 is embedded in the limiting groove 431 of the connecting bracket 400. The first plate 410 of the connecting bracket 400 is fixedly mounted on the swing table 332 of the angle displacement mechanism 330 by screws. The front end of the ultrasonic probe 10 can be completely immersed in the horizontal plane of the water tank 120 by more than 5 mm.

[0091] Since the ultrasonic probe 10 is fixed on the swing table 332 of the angle displacement mechanism 330, the displacement of the ultrasonic probe 10 on the X-axis and Z-axis, as well as the swing angle around the Y-axis, can be adjusted through the three-way displacement adjustment mechanism 300, so that the signal emitting surface 101 of the ultrasonic probe 10 can be parallel to the signal reflecting surface 111 of the reflecting plate 110. In the adjustment process, the position and angle of the ultrasonic probe 10 are precisely adjusted by adjusting the control system in coordination with each driving member.

[0092] After the ultrasonic probe 10 is adjusted, an acoustic test can be performed through the acoustic test transmitting and receiving system. Among them, the acoustic test transmitting and receiving system can be connected to the test report generation system through a computer. Therefore, by automatically performing acoustic testing through the acoustic test transmitting and receiving system, and cooperating with the test report generation system, it is possible to directly generate a usable test report after the test data is automatically collected and processed. The entire test process can be controlled by a program, which significantly improves the test efficiency. According to experiments, a complete test of the ultrasonic probe 10 requires 2 to 3 hours for manual testing, while the ultrasonic probe acoustic test device of the embodiment of the present application can be completed within 0.5 hours.

[0093] The ultrasonic probe acoustic testing device of the embodiment of the utility model can adjust the displacement of the ultrasonic probe 10 on the X-axis and Z-axis, and the swing angle around the Y-axis through the three-way displacement adjustment mechanism 300, so that the signal emitting surface 101 of the ultrasonic probe 10 can be parallel to the signal reflecting surface 111 of the reflecting plate 110. By adjusting the position and angle of the ultrasonic probe 10 through the three-way displacement adjustment mechanism 300, the error of manual adjustment is reduced, the adjustment efficiency and the test efficiency are improved, and the test accuracy is improved.

[0094] The ultrasonic probe 10 is fixed by the probe fixing frame 200, and then the probe fixing frame 200 is fixed to the swing table 332 through the connecting bracket 400. In this way, the ultrasonic probe 10 can be initially limited and fixed, thereby reducing the operation steps during adjustment and alignment, and improving the adjustment efficiency. Specifically, there is no need to adjust the displacement of the ultrasonic probe 10 along the Y axis, the angle of rotation around the X axis, and the angle of rotation around the Z axis. Instead, the displacement of the ultrasonic probe 10 on the X axis and the Z axis, as well as the angle of swing around the Y axis, are adjusted by the three-way displacement adjustment mechanism 300, so that the signal emitting surface 101 of the ultrasonic probe 10 can be parallel to the signal reflecting surface 111 of the reflecting plate 110. Thereby, the steps of aligning the signal emitting surface 101 of the ultrasonic probe 10 in parallel with the signal reflecting surface 111 of the reflecting plate 110 are effectively reduced, the adjustment efficiency is improved, and then the test efficiency is improved.
