Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic gun transducer sealing detection, and in particular to a multi-station transducer sealing detection tool and a sealing detection device thereof. Background Art

[0002] An ultrasonic cannon transducer is a core component connected to the ultrasonic cannon mainframe for energy conversion. It generally consists of a housing, a piezoelectric ceramic disc, an insulating sleeve, and connecting components. The piezoelectric ceramic disc is mounted on the inside of the housing, and an isolation cavity for mounting internal electrical components must be separated between the disc and the housing. A water bladder is installed at the front end of the piezoelectric ceramic disc. To prevent moisture from entering the isolation cavity and affecting the operation of the internal electrical components, the connection between the piezoelectric ceramic disc and the housing must be completely sealed using methods such as glue filling. After assembly of the piezoelectric ceramic disc, housing, and other components, the sealing performance of the connection must be tested.

[0003] In this regard, a Chinese patent with publication number CN221594206U and publication date 2024.08.23 proposes an airtightness detection tool for the upper section of the ultrasonic knife transducer shell. The airtightness detection tool is driven by a lifting mechanism to move the sealing and inflating head up and down to engage with or detach from the workpiece. When the sealing and inflating head is engaged with the workpiece, a sealing structure with a cavity is formed between the sealing and inflating head and the inner periphery of the upper section of the shell. The airtightness detection of the upper section of the transducer shell is achieved by filling gas into the sealing structure.

[0004] The transducer housing airtightness testing fixture has at least the following potential drawbacks when in use: For example, the sealing and inflating head can only perform airtightness testing on one housing workpiece at a time, failing to meet the requirements for efficient batch testing. Therefore, there is an urgent need for a sealing testing device that can simultaneously perform airtightness testing or sealing tests on multiple workpieces with a single clamping operation.

In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0032] Example 1:

[0033] The embodiments of this specification propose a multi-station transducer seal testing tool, which aims to address the problem that existing transducer airtightness testing tooling lacks the ability to efficiently perform batch testing. This tool not only enables simultaneous seal testing of multiple workpieces through a single clamping operation, significantly improving testing efficiency, but also ensures a safe and reliable testing process, effectively avoiding testing errors caused by human intervention.

[0034] like Figures 1 to 4As shown, the sealing detection tooling specifically includes a positioning seat 1, a clamping seat 2, and a driving component 4 that drives the clamping seat 2 to approach the positioning seat 1 to clamp the workpiece or away from the positioning seat 1 to release the workpiece. The positioning seat 1 has a plurality of first recesses 11, and the clamping seat 2 has a plurality of second recesses 21. The plurality of first recesses 11 correspond one-to-one with the plurality of second recesses 21 to define a plurality of clamping spaces for clamping the workpiece between the clamping seat 2 and the positioning seat 1. In each of the clamping spaces, an independent sealing detection cavity 22 is formed by the first recess 11 or the second recess 21 and the end face 7 of the workpiece to be inspected, and also includes an inflation channel 3 that is connected to each of the sealing detection cavities 22.

[0035] When the batch of materials arrives, the operator or the robot can first move the transducer workpiece to the first recess 11 on the positioning seat, refer to Figures 1 to 3 As shown, in this embodiment, the positioning seat 1 has 8 first recesses 11, thus generating 8 inspection stations. In other embodiments, the number of stations can also be increased or decreased according to the specific use environment. Then the driving component 4 is started to drive the clamping seat 2 to move toward the positioning seat 1 until the workpiece is clamped between the corresponding first recess 11 and the second recess 21, that is, in the corresponding clamping space. Figures 3 to 4 As shown, in this embodiment, in each clamping space, a sealed detection cavity 22 is formed between the second recess 21 and the end face 7 of the workpiece to be detected. At this time, the detection gas is introduced into the inflation channel 3, and the detection gas is distributed along the channel into each sealed detection cavity 22. Figure 3 and 4 The middle arrow S1 shows the flow direction of the detection gas in the inflation channel 3. Furthermore, the gas leakage amount in each sealing detection cavity 22 is detected by a gas leakage detection instrument connected to each sealing detection cavity 22, and the sealing quality of the connection between the end face 7 to be detected of the workpiece and the workpiece mounting shell can be known.

[0036] Thus, it can be seen that by setting and cooperating the multiple first recesses 11 on the positioning seat 1 and the multiple second recesses 21 on the clamping seat 2, multiple independent clamping spaces can be formed between the clamping seat 2 and the positioning seat 1, so that multiple workpieces can be clamped and positioned, that is, multi-station workpiece clamping can be achieved. Furthermore, by setting the air filling channel 3, the test gas can be simultaneously filled into each independent sealing detection cavity 22 to detect the sealing between the end face 7 of the workpiece to be tested and its mounting shell. In this way, multiple workpieces can be clamped at one time and the sealing of the multiple workpieces can be tested at the same time, which can meet the needs of efficient batch testing.

[0037] Here, the workpiece end surface 7 to be inspected can be the surface of a piezoelectric ceramic sheet. The piezoelectric ceramic sheet and the mounting housing form a sealed isolation cavity for mounting the electrical components within the transducer. Alternatively, a sealing sheet with a different purpose can be used, which will not be detailed here.

[0038] As shown in Figures 3, 4, and 6, in this embodiment, the inflation channel 3 is disposed within the clamping base 2. The inflation channel 3 includes an inflation hole 31, multiple air outlet holes 32, and an air distribution cavity 33. One end of the inflation hole 31 is connected to the gas source and the other end is connected to the air distribution cavity 33. The multiple air outlet holes 32 correspond one-to-one to the multiple sealing detection cavities 22, and one end of each of the air outlet holes 32 is connected to the corresponding sealing detection cavity 22 and the other end is connected to the air distribution cavity 33. During testing, the operator turns on the gas source, and the test gas enters the air distribution cavity 33 through the inflation hole 31 and is then distributed to each sealing detection cavity 22.

[0039] Preferably, an annular sealing gasket 23 is provided in each of the second recesses 21. When the workpiece is in a clamped state, the surface of the sealing gasket 23 is pressed against the end edge of the workpiece. During detection, the detection gas discharged from the air outlet 32 ​​can pass through the center hole of the sealing gasket 23 and enter the sealed detection cavity 22.

[0040] Preferably, the clamping seat 2 includes a seat body and an inflation cover 5 connected to the seat body, and the inflation cover is provided with an inflation hole 31. Here, the inflation cover 5 can be connected to the clamping seat 2 in a detachable manner, such as detachably fixed by screws or fixed by snapping, or can be connected in a non-detachable manner, such as rotatably connected to the clamping seat 2 by a rotating shaft. In this case, the inflation cover 5 is still connected to the clamping seat 2 in the open state.

[0041] Preferably, the side wall of the clamping seat 2 is recessed inward to form a side mounting groove for installing the inflation cover 5, and the air distribution cavity 33 is formed at the bottom of the side mounting groove. After the inflation cover 5 is installed in place, the cavity of the air distribution cavity 33 is located between the inflation cover 5 and the clamping seat 2.

[0042] The main functions of setting the inflation cover 5 here are, firstly, to facilitate cleaning of particles blocked inside the gas distribution cavity 33 and the air outlet 32 ​​after opening the inflation cover 5; secondly, during the assembly process of the tooling, the inflation nozzle on the air source can be first installed on the inflation cover 5, and then the inflation cover 5 can be installed on the clamping seat 2. The installation of the inflation cover 5 is relatively quick and convenient, thereby simplifying the assembly process between parts and facilitating inspection and maintenance.

[0043] Furthermore, the inflation cover 5 can be configured in a strip-shaped, disc-shaped, etc., and no further restrictions are imposed herein. As an easily conceivable structure, the inflation cover 5 can also be omitted, and the air distribution cavity 33 can be provided inside the clamping seat 2. The inflation hole 31 is provided on the clamping seat 2, with one end extending outward through the outer wall of the clamping seat 2 and the other end communicating with the air distribution cavity 33. This can also achieve the technical purpose of inflating the air distribution cavity 33, but it is not convenient for the inspection and maintenance of the interior of the inflation channel 3. Technicians can make choices based on the usage scenario.

[0044] It should be noted that, in this embodiment, the clamping seat 2 and the positioning seat 1 are arranged relative to each other in the longitudinal direction. As an extended implementation method, the clamping seat 2 and the positioning seat 1 can also be arranged relative to each other in the horizontal direction, or in the inclined direction. No further restrictions are made here, as long as the clamping and positioning of the workpiece can be achieved.

[0045] In order to facilitate the description of the specific details of this embodiment, the following description will be given by taking the example of the two being arranged relative to each other in the vertical direction.

[0046] refer to Figure 1 As shown, in this embodiment, the positioning seat 1 may include a base plate and a positioning template detachably connected to the base plate, wherein the four corners of the bottom of the base plate are provided with foot cups for supporting the base plate. The positioning template is mounted on the base plate via threaded fasteners, and the plurality of first recesses 11 are formed on the positioning template. With this positioning seat structure, since the positioning template can be individually customized based on the number of workstations, workpiece positioning dimensions, and other factors, different positioning templates can be replaced during the inspection process according to different process or product requirements, thereby providing a high degree of flexibility and adaptability in the inspection tooling.

[0047] Similarly, the clamping base 2 may also include an upper base plate and a clamping template detachably connected to the upper base plate, wherein the top of the upper base plate is connected to the driving component 4, the clamping template is mounted on the upper base plate via threaded fasteners, and the plurality of second recesses 21 are formed on the clamping template. Different clamping templates can be replaced according to different process or product requirements, and the clamping template and positioning template are mutually compatible, making the inspection tooling highly flexible and adaptable.

[0048] refer to Figure 5As shown, in this embodiment, the positioning seat 1 can also adopt an integral seat plate structure. In this case, the first recess 11 is opened on the seat plate, the bottom of the seat plate is supported by the foot cup, and the driving component 4, the guide component 6 and other components are installed on the upper part of the seat plate. Although this positioning seat structure can also achieve the technical purpose of clamping and positioning the workpiece, since the positioning seat 1 is a non-detachable integral structure, during inspection, the workpiece can only be accommodated by the first recess 11 with a specific size. Therefore, the scope of application of the inspection tooling is very limited.

[0049] Similarly, the clamping seat 2 can also adopt an integral seat plate structure, that is, the upper seat plate and the clamping template are integrally formed and connected. At this time, the second recess 21 is opened at the lower part of the seat plate, and the upper part of the seat plate is connected to the driving component 4, the guide component 6 and other components.

[0050] Preferably, a through groove is provided in the center of the base plate which passes through the base plate in the longitudinal direction, and an air leakage hole is provided inside each of the first recesses 11 for discharging excess gas leaked from the corresponding sealed detection cavity 22. When the positioning template is installed on the base plate, each air leakage hole is connected to the through groove so that the leaked excess gas can be discharged to the outside.

[0051] Preferably, the first recess 11 can be configured as a stepped hole with a positioning step, and during inspection, the bottom end of the workpiece rests on the positioning step. Of course, the first recess 11 can also be configured as a groove, in which case the air vent can be provided at the bottom of the groove.

[0052] Preferably, the second recess 21 is configured to be groove-shaped, and the air outlet is opened along the center of the second recess 21 .

[0053] refer to Figure 1 and 5 As shown, in this embodiment, the clamping base 2 is configured to reciprocate relative to the positioning base 1 between a workpiece clamping position and a workpiece release position. The driving component 4 specifically includes a movement mechanism for driving the clamping base 2 to reciprocate relative to the positioning base 1 between the workpiece clamping position and the workpiece release position. Specifically, the driving component 4 comprises a linear cylinder, and the positioning base 1 is provided with a drive control valve 42 for controlling the opening and closing of the driving component 4. It is understood that the linear cylinder described here can also be replaced with structures such as a linear slide or linear motor, which will not be described in detail here.

[0054] In this embodiment, a door-shaped mounting seat is connected to the base plate. Here, the door-shaped mounting seat is composed of two profile columns arranged opposite to each other on the base plate and a mounting top plate erected between the two profile columns.

[0055] In order to ensure the positional accuracy of the clamping seat 2 during linear movement, the inspection fixture also includes a guide component 6 for guiding the clamping seat 2 to reciprocate linearly relative to the positioning seat 1. Specifically, the guide component 6 includes two guide posts arranged relative to each other on the mounting top plate, the lower ends of the guide posts are connected to the clamping seat 2, and the outer sides of the guide posts are connected to the mounting top plate via linear bearings. The driving component 4 is arranged in the center of the mounting top plate, and its bottom end can be connected to the clamping seat 2 via a floating joint 41. For example, when the driving component 4 adopts a linear cylinder, the piston rod end of the linear cylinder is connected to the clamping seat 2 via a floating joint 41. The provision of the floating joint 41 can, on the one hand, bridge the deviation of the clamping seat 2 during movement, ensuring that the guide post and the piston rod are always in a relatively parallel state during movement. On the other hand, it can prevent interference between the guiding process of the guide post on the clamping seat 2 and the driving process of the linear cylinder on the clamping seat 2 within a certain range, ensuring that the piston rod can move smoothly along the axial direction in the cylinder.

[0056] This embodiment further provides a transducer sealing detection device, comprising the above-mentioned transducer sealing detection tooling, a gas leakage detection instrument connected to each of the sealing detection cavities, and an inflation gas source connected to the inflation channel 3 .

[0057] Example 2:

[0058] like Figure 7 As shown, this embodiment differs from the first embodiment in that, within each clamping space, a sealed inspection cavity 22 is formed by the first recess 11 and the workpiece end face 7 to be inspected, and the gas filling passage 3 is formed on the positioning seat 1. During inspection, inspection gas enters the sealed inspection cavity 22 through the gas filling passage 3 within the positioning seat 1. By detecting gas leakage within the sealed inspection cavity 22, the sealing quality between the workpiece end face 7 to be inspected and its mounting housing is determined.

[0059] Preferably, the inflation channel 3 can adopt a structure basically the same as that of Example 1, that is, a structure including an inflation hole, an air distribution cavity and multiple air outlet holes. In this way, the air distribution cavity 33 can be used to distribute the detection gas filled in the channel 3 along the multiple air outlet holes to each sealed detection cavity 22.

[0060] Correspondingly, an inflation cover 5 with an inflation hole 31 is installed on the positioning seat 1 .

[0061] Correspondingly, the second recess 21 is provided with an air leakage hole.

[0062] Correspondingly, an annular sealing gasket 23 is provided in each of the first recesses 11. When the workpiece is in a clamped state, the surface of the sealing gasket 23 is pressed against the end edge of the workpiece, and the detection gas discharged from the air outlet 32 ​​can pass through the center hole of the sealing gasket 23 and enter the sealed detection cavity 22, where the arrow S1 roughly shows the flow direction of the detection gas in the inflation channel 3.

[0063] The parts not described in this embodiment are the same as those in the first embodiment and will not be described in detail here.

[0064] Example 3:

[0065] like Figure 8 As shown, the difference between this embodiment and embodiment one and embodiment two is that the clamping seat 2 is configured to rotate back and forth between the workpiece clamping position and the workpiece releasing position relative to the positioning seat 1. For example, the clamping seat 2 can be rotatably connected to the positioning seat 1 via a rotating shaft. Accordingly, the driving component 4 adopts a driving mechanism, such as a rotary cylinder, that drives the clamping seat 2 to rotate back and forth between the workpiece clamping position and the workpiece releasing position relative to the positioning seat 1. In this case, although the guide component 6 does not need to be provided, it is still necessary to ensure the position accuracy of the clamping seat 2 during rotation, so as to prevent the corresponding first recess 11 and second recess 21 from being misaligned when in the workpiece clamping position, thereby causing damage to the workpiece.

[0066] The connection method between the clamping seat 2 and the positioning seat 1 in this embodiment can also achieve the technical purpose of multi-station clamping and positioning workpieces. However, since the clamping seat 2 and the positioning seat 1 need to be connected by connecting parts such as rotating shafts and hinges, the position and distance between the clamping seat 2 and the positioning seat 1 have been restricted to a certain extent. Therefore, this embodiment can only be applied to the sealing detection of smaller transducer workpieces. Technical personnel can independently select and design according to the size requirements and process requirements of the workpiece to be detected.

[0067] In summary, in the above embodiment, by setting and cooperating the multiple first recesses 11 on the positioning seat 1 and the multiple second recesses 21 on the clamping seat 2, multiple independent clamping spaces can be formed between the clamping seat 2 and the positioning seat 1, so that multiple workpieces can be clamped and positioned, that is, multi-station workpiece clamping can be achieved. Furthermore, by setting the inflation channel 3, the detection gas can be simultaneously filled into each independent sealing detection chamber 22 to detect the sealing between the end face 7 of the workpiece to be inspected and its mounting shell. In this way, multiple workpieces can be clamped at one time and the sealing of the multiple workpieces can be tested at the same time, which can meet the needs of efficient batch testing.

[0068] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0069] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
