Description

Technical Field

[0001] This invention belongs to the field of ultrasonic transducer assembly technology, specifically relating to ultrasonic transducer assembly equipment. Background Technology

[0002] An ultrasonic transducer consists of an amplitude transformer, multiple piezoelectric ceramic plates, and a rear end. It is a core component of CNC ultrasonic machining tools, ultrasonic welding machines, graphene circulating ultrasonic dispersers, and wastewater ultrasonic treatment equipment. It converts the electrical signal output from an ultrasonic generator into ultrasonic waves and focuses and amplifies them.

[0003] With the development of intelligent devices, the requirements for ultrasonic transducers are becoming increasingly stringent. To meet the requirements of ultrasonic transducers with small diameters and short lengths, a half-wavelength ultrasonic transducer was designed, consisting of a quarter-wavelength piezoelectric transducer and a quarter-wavelength amplitude transformer. Multiple piezoelectric ceramic plates of the half-wavelength transducer are directly mounted on the input end face of the amplitude transformer, with the rear end threadedly connected to the amplitude transformer to clamp the piezoelectric ceramic plates. To ensure the transduction efficiency and energy output of the piezoelectric ceramic plates, and to avoid mechanical stress on the ultrasonic transducer that could lead to cracking or failure of the piezoelectric ceramic plates, thus affecting the service life and reliability of the entire transducer, the assembled amplitude transformer, rear end, and the circumferences of the multiple piezoelectric ceramic plates must be on the same plane. However, to prevent short circuits caused by contact between the bolts on the amplitude transformer and the piezoelectric ceramic plates, reduce stress concentration, and evenly distribute pressure to prevent damage to the piezoelectric ceramic plates due to excessive stress, a PVC pipe is installed between the inner wall of the piezoelectric ceramic plates and the amplitude transformer. Since the PVC pipe is a soft material, the piezoelectric ceramic plates also have a certain amount of radial movement space. Currently, manual assembly is slow and there are errors in the torque during assembly. When using automated equipment for assembly, the piezoelectric ceramic sheet may shift, and it is difficult to restore the position of the piezoelectric ceramic sheet after assembly. In order to solve these problems, an ultrasonic transducer assembly device is proposed. Summary of the Invention

[0007] According to one embodiment of the present invention, the cross-section of the support portion is a U-shaped structure, and a portion of the circumferential surface of the amplitude rod, the piezoelectric ceramic sheet, and the rear end is in contact with the U-shaped structure to limit the amplitude rod, the piezoelectric ceramic sheet, and the rear end.

[0008] According to one embodiment of the present invention, the adjustment assembly includes a second driving part, and a push plate is provided on the output end of the second driving part. The push plate is located above the support part, and the output end of the second driving part is used to drive the push plate to approach or move away from the piezoelectric ceramic sheet, so as to cooperate with the support part to adjust the position of the piezoelectric ceramic sheet.

[0009] According to one embodiment of the present invention, the pusher plate has a V-shaped structure, and the open end of the pusher plate faces the piezoelectric ceramic sheet to increase the contact area when adjusting the position of the piezoelectric ceramic sheet.

[0010] According to one embodiment of the present invention, the pushing part includes a torque converter, the torque converter is disposed on a support platform, the output end of the torque converter faces the amplitude transformer, and a pneumatic-hydraulic device is disposed above the torque converter for controlling the opening and closing of the torque converter.

[0011] According to one embodiment of the present invention, the support platform is a disk, the support components are multiple, the number of tightening parts is half the number of support components, and the multiple support components and multiple tightening parts are evenly distributed along the circumferential direction of the support platform.

[0012] According to one embodiment of the present invention, the first drive unit includes a first motor, a drive shaft and a support unit. The first motor is mounted on a base, the drive shaft passes through the base, and both ends of the drive shaft are respectively connected to the output end of the first motor and the support platform. One end of the support unit is fixedly connected to the base, and the other end of the support unit is rotatably connected to the support platform.

[0013] According to one embodiment of the present invention, there are multiple support units, which are evenly arranged along the circumferential direction of the support platform. Each support unit includes a support frame and a bearing. The bearing is fixed on the support frame, the upper edge of the bearing is higher than the upper surface of the support frame, and the upper edge of the bearing is in rolling connection with the lower surface of the support platform.

[0014] According to one embodiment of the present invention, the first driving unit further includes a second motor, a driven shaft, a driven wheel, and a driving wheel; the second motor is disposed on the base, the output end of the second motor is connected to the driven shaft, the driven wheel is disposed on the driven shaft, the driving wheel is disposed on the driving shaft, and the driven wheel and the driving wheel are partially meshed.

[0015] An ultrasonic transducer assembly device includes the following steps:

During this process, a photographic component is used to detect the position of the piezoelectric ceramic sheet, and an adjustment component is used to adjust the position of the piezoelectric ceramic sheet, ensuring that any piezoelectric ceramic sheet that has shifted during assembly returns to its original position. This avoids the phenomenon that a shifted piezoelectric ceramic sheet cannot be repositioned after assembly. Furthermore, the use of automated equipment avoids uneven torque caused by manual operation, ensuring that the assembly of the amplitude transformer, piezoelectric ceramic sheet, and rear end is completed successfully in one go, improving the yield rate and accelerating the assembly speed.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The ultrasonic transducer assembly apparatus according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] like Figure 1-7As shown, the ultrasonic transducer assembly device according to an embodiment of the present invention includes: a base 1, a conveying unit, an assembly unit, and a detection unit; the conveying unit includes a support platform 21 and a first driving part, the first driving part being disposed on the base, and the output end of the first driving part being connected to the support platform 21; the assembly unit includes a support assembly and a tightening part 33; the support assembly is disposed on the conveying unit, and the tightening part 33 is disposed on the base 1, the support assembly including a supporting part 31 and a pushing part 32; the pushing part 32 and the tightening part 33 are arranged opposite to each other, and the supporting part 31 is located between the pushing part 32 and the tightening part 33. Between the parts 33, the supporting part 31 is used to support the amplitude rod 51, the piezoelectric ceramic sheet 52 and the rear end 53, and the pushing part 32 is used to push the rear end 53. Both the supporting part 31 and the pushing part 32 are provided on the support platform 21. The tightening part 33 is used to rotate the amplitude rod 51 to tighten the rear end 53 and the amplitude rod 51. The detection unit includes a photographing component 41 and an adjusting component 42. The photographing component 41 is used to detect the position change of the piezoelectric ceramic sheet 52 during the tightening process of the rear end 53 and the amplitude rod 51, and the adjusting component 42 is used to adjust the position of the piezoelectric ceramic sheet 52.

[0039] In this embodiment, the first drive unit drives the support platform 21 to rotate, causing the support platform 21 to move the assembly unit to the material feeding position or working position, so that the workers can feed the materials. During the assembly process, the imaging component 41 is used to detect the position change of the piezoelectric ceramic sheet 52, and the adjustment component 42 is used to adjust the position of the piezoelectric ceramic sheet 52, so that the piezoelectric ceramic sheet 52 that has shifted during the assembly process is returned to its original position. This avoids the phenomenon that the position of the piezoelectric ceramic sheet 52 that has shifted during assembly cannot be adjusted after assembly. In this process, the use of automated equipment avoids the phenomenon of uneven torque caused by manual operation, so that the assembly process of the amplitude rod 51, piezoelectric ceramic sheet 52 and rear end 53 is qualified in one go. Therefore, the qualification rate of the finished product is improved and the assembly speed is accelerated.

[0040] The cross-section of the support part 31 is U-shaped. Parts of the circumferential surfaces of the amplitude rod 51, the piezoelectric ceramic sheet 52 and the rear end 53 are in contact with the U-shaped structure to limit the amplitude rod 51, the piezoelectric ceramic sheet 52 and the rear end 53.

[0041] In this embodiment, the amplitude rod 51, the piezoelectric ceramic sheet 52, and the rear end 53 are in contact with the bottom inner surface of the support portion 31. Therefore, when the amplitude rod 51 and the rear end 53 are not tightened, the piezoelectric ceramic sheet 52 is kept on the same plane as the circumferential surface of the amplitude rod 51 and the rear end 53, preventing the piezoelectric ceramic sheet 52 from shifting to the left, right, and downward, thus achieving multi-directional limiting of the piezoelectric ceramic sheet 52.

[0042] The adjustment assembly 42 includes a second drive unit 421. A push plate 422 is provided on the output end of the second drive unit 421. The push plate 422 is located above the support unit 31. The output end of the second drive unit 421 is used to drive the push plate 422 to approach or move away from the piezoelectric ceramic sheet 52, so as to cooperate with the support unit 31 to adjust the position of the piezoelectric ceramic sheet 52. The push plate 422 has a V-shaped structure, and the open end of the push plate 422 faces the piezoelectric ceramic sheet 52, so as to increase the contact area with the piezoelectric ceramic sheet 52 when adjusting the position of the piezoelectric ceramic sheet 52.

[0043] In this embodiment, the second drive unit 421 is a pneumatic-hydraulic device, and the push plate 422 is opposite to and centrally located with the support unit 31. During the assembly process, if the piezoelectric ceramic sheet 52 is displaced, the second drive unit 421 will drive the push plate 422 to press down. At this time, the piezoelectric ceramic sheet 52 has not yet been clamped by the amplitude rod 51 and the rear end 53, so it is easier to push the piezoelectric ceramic sheet 52. Under the limitation of the V-shaped structure, the piezoelectric ceramic sheet 52 can gradually be centered when returning to its original position. Therefore, even if the displacement direction of the piezoelectric ceramic sheet 52 is to the upper left or upper right, it can still be gradually moved back to its original position by the push plate 422.

[0044] The propulsion unit 32 includes a torque converter 321, which is mounted on the support platform 21. The output end of the torque converter 321 faces the amplitude rod 51. A pneumatic-hydraulic device 322 is provided above the torque converter 321. The pneumatic-hydraulic device 322 is used to control the opening and closing of the torque converter 321.

[0045] In this embodiment, a support frame is fixedly installed on the base 1. The second drive unit 421 and the pneumatic-hydraulic device 322 are both installed on the support frame, thereby reducing the weight on the support platform 21, improving the stability of the support platform 21, and reducing the wear on the first drive unit. The upper end of the torque converter 321 has a start switch. The output end of the pneumatic-hydraulic device 322 is located directly above the start switch of the torque converter 321. The pressure value of the start switch of the torque converter 321 pressed down by the pneumatic-hydraulic device 322 determines the torsion angle of the torque converter 321. The pneumatic-hydraulic device 322 controls the torque converter 321. Compared with motor drive, its response speed is faster. It can react quickly when the piezoelectric ceramic plate 52 is detected to be displaced, and promptly stop the rotation of the amplitude rod 51.

[0046] The support platform 21 is a disc, and there are multiple support components. The number of tightening parts 33 is half the number of support components. The multiple support components and multiple tightening parts 33 are evenly distributed along the circumference of the support platform 21.

[0047] In this embodiment, the first driving unit drives the bearing platform 21 to rotate, thereby simultaneously driving multiple support components to rotate, so that multiple spaced support components correspond to the position of the tightening part 33. At this time, the tightening part 33 assembles the support components corresponding to its position, and at the same time, the ultrasonic transducer assembled on the support components that are offset from the tightening part 33 is taken out, and then the amplitude rod, piezoelectric ceramic sheet and rear end required for assembly are put in. In this process, the loading and unloading operations are realized by utilizing the assembly time, which speeds up the assembly speed and saves assembly time.

[0048] The first drive unit includes a first motor 221, a drive shaft 222, and a support unit 223. The first motor 221 is mounted on the base 1, and the drive shaft 222 passes through the base 1. The two ends of the drive shaft 222 are respectively connected to the output end of the first motor 221 and the support platform 21. The first motor 221 is used to drive the drive shaft 222 to rotate, so that the drive shaft 222 drives the support platform 21 to rotate. One end of the support unit 223 is fixedly connected to the base 1, and the other end of the support unit 223 is tactilely connected to the support platform 21. There are multiple support units 223, which are evenly arranged along the circumference of the support platform 21. Each support unit 223 includes a support frame and a bearing. The bearing is fixed on the support frame, and the upper edge of the bearing is higher than the upper surface of the support frame. The upper edge of the bearing is tactilely connected to the lower surface of the support platform 21.

[0049] In this embodiment, a support unit 223 is used to support the bearing platform 21, so that the rotating bearing platform 21 remains horizontal. This ensures the flatness of the placement of the amplitude rod 51, piezoelectric ceramic sheet 52 and rear end 53 during assembly, and avoids jamming caused by the angle tilt during assembly, which causes the force direction of the tightening part 33 to be different from the screwing direction of the amplitude rod 51. This ensures the smooth operation of the tightening part 33 and further guarantees the working speed.

[0050] The first drive unit also includes a second motor 231, a driven shaft 232, a driven wheel 233, and a driving wheel 224. The second motor 231 is mounted on the base 1, and the output end of the second motor 231 is connected to the driven shaft 232. The driven wheel 233 is mounted on the driven shaft 232, and the driving wheel 224 is mounted on the driving shaft 222. The driven wheel 233 and the driving wheel 224 are partially meshed.

[0051] In this embodiment, half of the circumferential surface of the driven wheel 233 is notched, and the other half is toothed and meshes with the driving wheel 224. When the first motor 221 drives the support platform 21 to move, the notch of the driven wheel 233 faces the driving wheel 224. At this time, the driven wheel 233 does not affect the rotation of the driving wheel 224. When the support platform 21 moves to the working position, the second motor 231 drives the driven wheel 233 to rotate and mesh with the driving wheel 224. At this time, the driven wheel 233 limits the driving wheel 224, preventing the driving wheel 224 from rotating. Also, due to the support of the driven wheel 233, the driving wheel 224 loses its space to wobble. Therefore, the effect of avoiding the rotation of the driving wheel 224 and the radial displacement of the support platform 21 is achieved.

[0052] The ultrasonic transducer assembly equipment includes the following steps:

[0053] S1. Preset the maximum displacement value of the piezoelectric ceramic sheet 52, set the torque for tightening between the amplitude rod 51 and the rear end 53, insert the amplitude rod 51, piezoelectric ceramic sheet 52 and rear end 53 into the support part 31, start the first motor 221, so that the first motor 221 drives the support platform 21 to rotate to the working position, that is, the position of part of the support component corresponds to the position of the tightening part 33;

[0054] S2. The second motor 231 drives the driven wheel 233 to rotate, so that it meshes with the driving wheel 224 to limit and support the driving wheel 224;

[0055] S3. The pusher 32 pushes the rear end 53, so that the rear end 53 presses the piezoelectric ceramic plate 52 and the amplitude rod 51. At the same time, the pneumatic hydraulic device (322) presses down the torque converter 321 to start the switch, so that the torque converter 321 drives the amplitude rod 51 to rotate, so that the amplitude rod 51 and the rear end 53 are tightened.

[0056] S4. During the process of tightening the amplitude rod 51 and the rear end 53, the camera component 41 continuously takes pictures and reads the position of the piezoelectric ceramic sheet 52. If the piezoelectric ceramic sheet 52 is displaced and the displacement exceeds the preset maximum displacement value, the pneumatic hydraulic device (322) is controlled to stop pressing down, the rotation of the tightening part 33 is paused, and the pushing part 32 is paused. At the same time, the adjustment component 42 is controlled to adjust the position of the piezoelectric ceramic sheet 52.

[0057] S5. After the position of the piezoelectric ceramic sheet 52 is adjusted, the pneumatic-hydraulic device (322) continues to press down the torque converter 321 start switch, and controls the tightening part 33 to tighten the amplitude rod 51 and the rear end 53 according to the torque requirement. After the assembly is completed, the pushing part 32 returns to its position, the pneumatic-hydraulic device (322) returns to its position, the second motor 231 drives the driven wheel 233 to rotate, and releases the limit on the driving wheel 224 so that the first motor 221 drives the support platform 21 to rotate.

[0058] In summary, during the assembly of the amplitude transformer 51, piezoelectric ceramic sheet 52, and rear end 53, the position of the piezoelectric ceramic sheet 52 was adjusted to ensure the alignment of the circumferential surface of the piezoelectric ceramic sheet 52 with the circumferential surfaces of the amplitude transformer 51 and the rear end 53, reducing the displacement of the piezoelectric ceramic sheet 52. This ensured the contact area between each piezoelectric ceramic sheet 52, achieving one-time assembly qualification and significantly improving the yield rate.
