Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning, in particular to a failure detection device for an ultrasonic transducer. Background Art

[0002] Ultrasonic wave is a kind of mechanical wave. Ultrasonic cleaning utilizes the cavitation effect, acceleration effect and rectilinear flow effect of ultrasonic wave in the cleaning liquid to vibrate and strip the dirt inside and outside the workpiece immersed in the cleaning liquid. In the related art, an ultrasonic transducer is needed to convert the input electric power into mechanical power (i.e., ultrasonic wave) and then transmit it to realize the propagation of ultrasonic wave in the cleaning liquid.

[0003] The electro-acoustic conversion efficiency of the ultrasonic transducer is relatively low, and most of the power will be converted into heat energy, resulting in an increased probability of the ceramic chip in the ultrasonic transducer being broken and damaged during the working process. To ensure the normal cleaning of the workpiece, it is necessary to perform failure detection on the ultrasonic transducer to screen out the failed and damaged ultrasonic transducers.

[0004] Therefore, there is an urgent need to invent a failure detection device for an ultrasonic transducer to solve the above problems. Content of the Utility Model

[0038] Embodiment 1

[0039] The electroacoustic conversion efficiency of the ultrasonic transducer is relatively low, and most of the power will be converted into heat energy, resulting in an increased probability of the ceramic chip in the ultrasonic transducer being broken and damaged during the working process. To ensure the normal cleaning of the workpiece, it is necessary to perform failure detection on the ultrasonic transducer to screen out the ultrasonic transducers that are damaged due to failure.

[0040] Therefore, as Figures 1 to 3As shown in the figure, this embodiment provides a failure detection device 1000 for an ultrasonic transducer. The failure detection device 1000 for the ultrasonic transducer includes a mounting member 100, a receiving housing 200, a control member (not shown in the figure), and a thermal imaging detection device 300. Among them, the receiving housing 200 has a receiving cavity 210 for receiving a cleaning liquid. An opening 211 is provided at the upper end of the receiving cavity 210. The mounting member 100 covers the opening 211. At least two ultrasonic transducers 2000 are mounted on the end face of the mounting member 100 close to the receiving housing 200. All the ultrasonic transducers 2000 are at least partially immersed in the cleaning liquid. The mounting member 100 has a heat conduction function. The control member can control the synchronous start and stop of all the ultrasonic transducers 2000. The thermal imaging detection device 300 is used to detect the infrared energy of the mounting member 100.

[0041] The failure detection device 1000 for the ultrasonic transducer sets a cleaning liquid in the receiving cavity 210 of the receiving housing 200, opens an opening 211 on the receiving cavity 210, covers the opening 211 with the mounting member 100, and mounts at least two ultrasonic transducers 2000 on the end face of the mounting member 100 close to the receiving housing 200, so that all the ultrasonic transducers 2000 are at least partially immersed in the cleaning liquid, and the control member synchronously controls the start and stop of all the ultrasonic transducers 2000, which can truly simulate the working environment of the ultrasonic transducers 2000. By ensuring that the mounting member 100 has a heat conduction function, using the heat generated during the working process of the ultrasonic transducers 2000, and using the thermal imaging detection device 300 to detect the infrared energy of the mounting member 100, it can be detected that the infrared energy at different positions of the mounting member 100 where the ultrasonic transducers 2000 are mounted is different, and then the failed parts among all the ultrasonic transducers 2000 can be accurately detected, with high detection efficiency and high detection accuracy.

[0042] It should be noted that in this embodiment, 8 ultrasonic transducers 2000 are mounted on the mounting member 100. In other embodiments, the specific number of ultrasonic transducers 2000 on the mounting member 100 can also be adjusted according to actual needs, and this embodiment does not make specific limitations.

[0043] As an optional solution, in this embodiment, the thermal imaging detection device 300 includes a thermal imaging probe (not shown in the figure) and a display (not shown in the figure). Among them, the thermal imaging probe is used to detect the infrared energy of the mounting member 100. The display is communicatively connected to the thermal imaging probe, and the display is used to display the detection information of the thermal imaging probe.

[0044] Specifically, when it is necessary to perform a failure detection on the ultrasonic transducers 2000 on the mounting member 100, first, the control member controls all the ultrasonic transducers 2000 on the mounting member 100 to start synchronously for about thirty minutes, and then the control member controls all the ultrasonic transducers 2000 on the mounting member 100 to stop synchronously. Use a thermal imaging probe to detect the mounting member 100. If only multiple red-pink regions are shown on the display, it indicates that none of the ultrasonic transducers 2000 on the mounting member 100 have failed. If only blue-green regions are shown on the display, it indicates that all the ultrasonic transducers 2000 on the mounting member 100 have failed. If both red-pink regions and blue-green regions are shown on the display, it indicates that some of the ultrasonic transducers 2000 on the mounting member 100 have not failed and some have failed. The non-failed ultrasonic transducers 2000 are correspondingly installed in the red-pink regions, and the failed ultrasonic transducers 2000 are installed in the blue-green regions.

[0045] It should be noted that in other embodiments, the working time of the ultrasonic transducers 2000 can also be adjusted according to actual needs, as long as it can be ensured that the color of the region where the failed ultrasonic transducers 2000 are installed on the mounting member 100 is different from the color of the region where the non-failed ultrasonic transducers 2000 are installed on the mounting member 100 in the subsequent precise detection. This embodiment does not make specific limitations. In addition, the specific structures and working principles of the control member, the thermal imaging probe, and the display all belong to the prior art and will not be elaborated here.

[0046] During the working process of the ultrasonic transducers 2000, since the mounting member 100 has thermal conductivity, the heat generated by the non-failed ultrasonic transducers 2000 during operation may be transferred to the corresponding region of the mounting member 100 and then to the corresponding region of the failed ultrasonic transducers 2000 on the mounting member 100, affecting the judgment of the detection result.

[0047] To solve the above problem, the distance between two adjacent ultrasonic transducers 2000 on the mounting member 100 is not less than 50 mm. By ensuring that the distance between two adjacent ultrasonic transducers 2000 on the mounting member 100 is not less than 50 mm, the heat transfer efficiency between the corresponding regions of two adjacent ultrasonic transducers 2000 on the mounting member 100 can be reduced, facilitating the observation of the detection result.

[0048] As an alternative, at least two first mounting grooves 110 are provided on the end surface of the mounting member 100 close to the receiving housing 200. The ultrasonic transducer 2000 is installed in the first mounting groove 110, and each first mounting groove 110 is correspondingly arranged with an ultrasonic transducer 2000. By providing at least two first mounting grooves 110 on the end surface of the mounting member 100 close to the receiving housing 200, installing the ultrasonic transducer 2000 in the first mounting groove 110, and ensuring that each first mounting groove 110 is correspondingly arranged with an ultrasonic transducer 2000, the mounting positioning accuracy and mounting and fixing efficiency of the ultrasonic transducer 2000 and the mounting member 100 can be provided. It should be noted that in this embodiment, 8 ultrasonic transducers 2000 are fixed on the mounting member 100, so 8 first mounting grooves 110 are provided on the mounting member 100. In other embodiments, the specific number of the first mounting grooves 110 can also be adjusted according to the specific number of the ultrasonic transducers 2000, and no specific limitation is made in this embodiment.

[0049] In an alternative embodiment, a second mounting groove 130 is provided on the end surface of the mounting member 100 close to the receiving housing 200, and the side wall of the receiving housing 200 is installed in the second mounting groove 130. By providing the second mounting groove 130 on the end surface of the mounting member 100 close to the receiving housing 200 and installing the side wall of the receiving housing 200 in the second mounting groove 130, the positioning accuracy of the mounting member 100 and the opening 211 on the receiving housing 200 can be provided.

[0050] In this embodiment, the mounting member 100 is made of 316 stainless steel material, and the mounting member 100 is plate-shaped with a thickness of 2 mm. The first mounting groove 110 and the second mounting groove 130 are both formed by stamping. The 316 stainless steel material has good strength and strong corrosion resistance. In other embodiments, the mounting member 100 can also be made of other materials with heat conduction functions, and the thickness of the mounting member 100 can also be adjusted according to actual needs, and no specific limitation is made in this embodiment.

[0051] As an alternative, a conduit 220 is provided on the receiving housing 200. One end of the conduit 220 communicates with the receiving cavity 210, and the other end of the conduit 220 extends outward. The connecting wire harness of the ultrasonic transducer 2000 extends outward along the conduit 220 and is connected to the control member. By providing the conduit 220 communicating with the receiving cavity 210 on the receiving housing 200, the connecting wire harness of the ultrasonic transducer 2000 is extended outward along the conduit 220 and connected to the control member wire harness, so that the connecting wire harnesses of the ultrasonic transducers 2000 on the mounting member 100 can be integrated together, which is convenient for arrangement. It should be noted that in this embodiment, both the receiving housing 200 and the conduit 220 are made of 316 stainless steel material. The wall thickness of the receiving housing 200 is 2 mm, the wall thickness of the conduit 220 is 2 mm, and the inner diameter is 8 mm. The 316 stainless steel material has good strength and strong corrosion resistance. In other embodiments, the receiving housing 200 and the conduit 220 can also be made of other materials, and the wall thickness of the receiving housing 200, the wall thickness of the conduit 220, and the inner diameter can all be adjusted according to actual needs, and this embodiment does not make specific limitations.

[0052] As Figures 1 to 3 shown, the mounting member 100 is provided with an extension portion 120. The extension portion 120 extends horizontally out of the open end 211. The extension portion 120 is provided with a positioning and fixing hole 121. The extension portion 120 and the external device are detachably fixed through the positioning and fixing hole 121. By providing the extension portion 120 extending horizontally outward on the mounting member 100 and providing the positioning and fixing hole 121 on the extension portion 120, the extension portion 120 and the external device are detachably fixed together through the positioning and fixing hole 121, which can effectively fix the mounting member 100 and the external device, and further effectively fix the ultrasonic transducer 2000 mounted on the mounting member 100 and the external device.

[0053] Specifically, the failure detection device 1000 of the ultrasonic transducer further includes a locking bolt (not shown in the figure). Among them, the inner cavity wall of the positioning and fixing hole 121 is provided with internal threads, and the external device is provided with a threaded blind hole coaxially arranged with the positioning and fixing hole 121. The locking bolt is threadedly fixed to the positioning and fixing hole 121 and the threaded blind hole in sequence. When it is necessary to connect and fix the mounting member 100 and the external device, first, the positioning and fixing hole 121 on the mounting member 100 and the threaded blind hole on the external device are arranged coaxially along the axis, and then the threaded end of the locking bolt is inserted into the positioning and fixing hole 121 and the locking bolt is screwed to make the locking bolt threadedly fixed to the positioning and fixing hole 121 and the threaded blind hole in sequence, so as to realize the connection and fixing of the mounting member 100 and the external device. When it is necessary to disassemble the mounting member 100 and the external device that are connected and fixed together, the locking bolt is screwed in the reverse direction to make the locking bolt disengage from the threaded blind hole and the positioning and fixing hole 121, so as to realize the disassembly of the mounting member 100 and the external device.

[0054] To further improve the fixing effect between the mounting member 100 and the external device, a plurality of positioning and fixing holes 121 are spacedly arranged on the extension portion 120, and the extension portion 120 and the external device are detachably fixed through the plurality of positioning and fixing holes 121. It should be noted that, in this embodiment, the mounting member 100 is rectangular, and extension portions 120 are arranged at both ends of the mounting member 100 along the length direction. Two positioning and fixing holes 121 are spacedly arranged on each extension portion 120, and each positioning and fixing hole 121 corresponds to a threaded blind hole and a locking bolt. In other embodiments, the specific number of the positioning and fixing holes 121 on the extension portion 120 can also be adjusted according to actual requirements, as long as it is ensured that each positioning and fixing hole 121 corresponds to a threaded blind hole and a locking bolt. In addition, in other embodiments, the threaded blind hole on the external device can also be replaced with a threaded through hole, which is not specifically limited in this embodiment.

[0055] Embodiment Two

[0056] This embodiment provides a failure detection device 1000 for an ultrasonic transducer. The failure detection device 1000 for an ultrasonic transducer provided in this embodiment is basically the same as that in Embodiment One. The difference between the failure detection device 1000 for an ultrasonic transducer provided in this embodiment and that in Embodiment One lies in: the connection and fixing method between the mounting member 100 and the external device is different.

[0057] Specifically, in this embodiment, the failure detection device 1000 for an ultrasonic transducer does not include a locking bolt. The failure detection device 1000 for an ultrasonic transducer includes a positioning and fixing pin. The external device is provided with a plugging blind hole coaxially arranged with the positioning and fixing hole 121, and the positioning and fixing pin is plugged and fixed with the positioning and fixing hole 121 and the plugging blind hole in sequence. By using the positioning and fixing pin to be plugged and fixed with the positioning and fixing hole 121 and the plugging blind hole in sequence, the positioning and fixing efficiency between the mounting member 100 and the external device can be further improved.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
