Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology, and in particular to a fluorescent penetrant detection line. Background Technology

[0002] In existing technologies, for defects such as tiny cracks that are difficult to see with the naked eye on the surface of the actuator's inner hole, fluorescent penetrant testing technology is widely used in the industry to detect these surface defects. Its principle is to allow a fluorescent penetrant to penetrate into the cracks on the surface of the actuator's inner hole through a certain method. After cleaning and drying, the penetrant and moisture on the surface of the actuator's inner hole are removed. Then, dry developing powder is applied to the surface of the actuator's inner hole. Under capillary action, the penetrant in the crack is adsorbed onto the surface of the actuator's inner hole, and then the defect is detected under a black light.

[0003] Most existing fluorescent penetrant testing lines employ a multi-functional slot, step-by-step operation, arranging these slots sequentially in an assembly line format for progressive testing. However, this type of testing line often requires multiple stations, with one station corresponding to each process, resulting in a large overall footprint. Furthermore, on a single testing line, workpieces in the previous process must wait for the next process to complete its testing before proceeding, leading to low efficiency. Moreover, when multiple workpieces need to be tested simultaneously, multiple testing lines are required, increasing costs.

[0004] Therefore, there is an urgent need to design a fluorescence penetrant detection line that has a small footprint, high detection efficiency, and low cost to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this invention is to provide a fluorescent penetrant detection line that has a small footprint, high detection efficiency, and low cost.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A fluorescent penetrant detection line for detecting the inner hole of an actuator, the fluorescent penetrant detection line comprising:

[0008] At least one fixing device for fixing the actuator;

[0009] Multiple working devices, which are capable of processing or inspecting the inner bore of the actuator;

[0010] A transfer device is available that can selectively fix and transfer the working device to the fixing device to process or inspect the inner hole of the actuator in sequence.

[0013] Optionally, the fixing device includes a fixing chamber for accommodating the actuator, the fixing chamber having a detection through hole, through which the working device can extend into the inner hole of the actuator.

[0014] Optionally, a limiting structure is provided in the fixed chamber to limit the actuator so that the inner hole of the actuator placed in the fixed chamber can be aligned with the detection through hole.

[0015] Optionally, the limiting structure includes at least one groove formed in the fixed chamber and a limiting block slidably connected in the groove, the limiting block being able to limit the actuator.

[0016] Optionally, the fixed chamber is provided with a support block to support the actuator, the support block is provided with a groove near the opening end of the actuator, the groove is movably provided with a limiting block for limiting the end of the actuator, the bottom of the groove is provided with a leakage hole, and the waste discharge structure is a liquid outlet channel that runs through the fixed chamber, the leakage hole is connected to the liquid outlet channel;

[0017] And / or, the fluorescence permeation detection line further includes a drive mechanism for driving the fixed chamber to rotate relative to the base.

[0018] Optionally, the fluorescence permeation detection line further includes a waste liquid collection device for collecting waste liquid flowing out from the waste discharge structure.

[0019] Optionally, the waste liquid collection device includes a waste liquid collection component and at least one waste liquid collection pipe. The waste liquid collection pipe is disposed on the waste liquid collection component and communicates with the interior of the waste liquid collection component. At least one of the waste liquid collection pipes is connected to the waste discharge structure of at least one of the fixed compartments in a one-to-one correspondence.

[0020] Optionally, the waste liquid collection component has a ring structure, and at least one of the fixing devices and multiple of the operating devices are arranged in a ring on the waste liquid collection component.

[0022] And / or, the fluorescence penetrant detection line further includes a placement stage, on which a placement slot is provided, and multiple of the working devices are placed in the placement slot when not in use.

[0023] The beneficial effects of this utility model are:

[0024] The fluorescent penetrant testing line provided by this utility model arranges at least one fixed device and multiple working devices circumferentially around a transfer device, allowing multiple working devices to share a single workstation. Compared to the existing streamlined testing line structure where each process requires a separate workstation, this reduces the space occupied by the testing line. Furthermore, when multiple fixed devices are present, if the actuator in one fixed device is in a time-consuming processing or testing phase, the transfer device can be used to process or test the actuators in other fixed devices during that time period. This allows multiple actuators to be processed or tested simultaneously on a single testing line, making full use of time and improving work efficiency. Moreover, compared to the existing technology that requires multiple testing lines to test multiple actuators simultaneously, this also reduces testing costs. Attached Figure Description

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] like Figures 1 to 9 As shown, the fluorescent penetrant detection line provided in this embodiment is mainly used to detect the inner surface of the actuator 9, including a fixing device 1, multiple working devices 2, and a transfer device 3. The fixing device 1 is used to fix the actuator 9, the working devices 2 can process or detect the inner surface of the actuator 9, and the transfer device 3 can selectively fix and transfer the working devices 2 to the fixing device 1 to sequentially process or detect the inner surface of the actuator 9.

[0052] This fluorescence penetrant testing line, through the aforementioned arrangement, allows multiple working devices 2 to be concentrated at one workstation. When different work steps are required, the transfer device 3 can be controlled to move the corresponding working device 2 to the fixed device 1 for operation, eliminating the need for each working device 2 to have a separate workstation. This reduces the footprint of the working devices 2, resulting in a smaller overall footprint for the fluorescence penetrant testing line. Furthermore, when there are multiple fixed devices 1, they are arranged circumferentially around the transfer device 3 with multiple working devices 2 at intervals. This arrangement allows the transfer device 3 to process or test the inner holes of other actuators 9 while one actuator 9 in a time-consuming processing or testing stage is in progress. This fully utilizes the waiting time and enables simultaneous processing or testing of multiple actuators 9 on a single testing line. This not only improves testing efficiency but also further reduces the footprint and testing cost compared to existing technologies that require multiple testing lines to process multiple actuators 9 simultaneously.

[0053] like Figure 2 and Figure 3 As shown, the fixing device 1 includes a fixing chamber 11, and the fixing chamber 11 is provided with a receiving chamber for accommodating the actuator 9, and the actuator 9 is placed in the fixing chamber 11.

[0054] Optionally, such as Figure 3 As shown, in this embodiment, the fixed chamber 11 includes an upper shell 111 and a lower shell 112.

[0055] In some embodiments, such as Figure 4 As shown, the upper shell 111 is generally a semi-cylindrical shell structure, which includes two parallel semi-circular sidewalls and a curved wall panel that connects the arcuate portions of the two semi-circular sidewalls together. The bottom edges of the two semi-circular sidewalls and the two ends of the curved wall panel form a rectangular opening.

[0056] In some embodiments, such as Figure 5 As shown, the lower housing 112 includes two parallel semi-circular sidewalls and a first top wall plate that connects the bottom edges of the two semi-circular sidewalls together. The first top wall plate has a rectangular structure and its shape and size are the same as the opening of the upper housing 111, so that the opening side of the upper housing 111 can be placed on the first top wall plate of the lower housing 112.

[0057] During the assembly of the upper housing 111 and the lower housing 112, after the opening of the upper housing 111 is placed facing the first top wall plate of the lower housing 112, the inner wall surface of the upper housing 111 and the inner wall surface of the lower housing 112 form a receiving compartment for accommodating the actuator 9.

[0058] It is understood that in some other embodiments, the fixing chamber 11 may also be a structure of other shapes, as long as it can be used to accommodate the actuator 9, and there is no limitation here.

[0059] Alternatively, in this embodiment, the upper housing 111 and the lower housing 112 are detachably connected. The detachable connection can be made in ways including but not limited to fastening, connecting with connectors, rotational connection and locking combination. The detachable connection between the upper housing 111 and the lower housing 112 facilitates the placement and removal of the actuator 9, and also facilitates the cleaning of the internal structure of the upper housing 111 and the lower housing 112.

[0060] It is understood that in some other embodiments, the upper housing 111 and the lower housing 112 may be connected in other ways, such as a fixed connection between the upper housing 111 and the lower housing 112, and a window for taking out and putting in the actuator 9 is opened on the upper housing 111. This is not a limitation.

[0061] To prevent the actuator 9 inside the fixed chamber 11 from shifting during the testing process, thereby affecting the efficiency and accuracy of the working device 2, a limiting structure is also provided inside the fixed chamber 11. This limiting structure is used to limit the actuator 9 to avoid the actuator 9 shifting during the testing process.

[0062] Optionally, the limiting structure includes at least one groove formed in the fixed chamber 11 and a limiting block 8 slidably connected in the groove, the limiting block 8 being able to limit the actuator 9. Optionally, multiple grooves are provided, each groove having two limiting blocks 8. By moving the limiting blocks 8 in the groove, multiple limiting blocks 8 can press against different positions on the outer wall of the actuator 9, thereby limiting the actuator 9. In a specific embodiment, two grooves are provided, namely a first groove 71 and a second groove 72, the first groove 71 and the second groove 72 being spaced apart in the axial direction of the actuator 9. The first groove 71 has two limiting blocks 8, which can press against the open end of the actuator 9. The second groove 72 also has two limiting blocks 8, which press against the two sides of the middle part of the actuator 9 respectively.

[0063] In order to form a chute within the fixed chamber 11, in some embodiments, such as Figure 5 and Figure 6 As shown, in this embodiment, a groove 1123 is provided on the first top wall plate of the lower shell 112, and a support block 7 is placed in the groove 1123. A first sliding groove 71 and a second sliding groove 72 are provided on the support block 7.

[0064] After the actuator 9 is placed on the support block 7, the end of the actuator 9 furthest from the opening is first placed against the side wall of the groove 1123; then the two limiting blocks 8 in the first slide groove 71 are moved to abut against the end face of the opening of the actuator 9 to limit the front-back direction of the actuator 9; finally, the two limiting blocks 8 in the second slide groove 72 are moved to abut against the left and right sides of the actuator 9 respectively to limit the left and right directions of the actuator 9, thereby fixing the position of the actuator 9.

[0065] It is understood that in some other embodiments, several grooves perpendicular or parallel to the placement direction of the actuator 9 can be directly formed on the first top wall plate of the lower housing 112, and several limiting blocks 8 can be placed in the grooves. When the actuator 9 is placed on the first top wall plate of the lower housing 112, the limiting blocks 8 in the grooves can be moved to abut against the periphery of the actuator 9 to limit the actuator 9. In this case, it is not necessary to form a groove 1123 on the first top wall plate of the lower housing 112 and to set a support block 7 in the groove 1123. Of course, in some other embodiments, other forms of limiting structures can be set in the fixing chamber 11, as long as they can limit the actuator 9, which is not limited here.

[0066] Some working devices 2 need to inject liquid into the inner hole of the actuator 9. After the liquid completes its task, it becomes waste liquid and is discharged. In order to facilitate the discharge of waste liquid generated during the detection process, the fixed chamber 11 is also provided with a waste discharge structure. The waste discharge structure can connect the chamber to the outside, so that the waste liquid generated during the detection process can be discharged through the waste discharge structure after flowing out of the inner hole of the actuator 9.

[0067] Optionally, such as Figure 5 As shown, in this embodiment, a liquid outlet channel 1124 is provided on the first top wall plate of the lower housing 112, which is the aforementioned waste discharge structure. The waste liquid generated during the detection process flows out from the inner hole of the actuator 9 and can be discharged through the liquid outlet channel 1124 on the top wall of the lower housing 112.

[0068] It is understood that in some other embodiments, the waste discharge structure can be adapted to the shape of the fixed chamber 11 and the specific position of the actuator 9 in the fixed chamber 11, as long as the waste liquid can be discharged, and no restrictions are imposed here.

[0069] When the actuator 9 is mounted on the support block 7, in order to facilitate the smooth discharge of waste liquid from the actuator 9 into the liquid outlet channel 1124, such as Figure 5 and Figure 6As shown, in this embodiment, the first groove 71 on the support block 7 is opened directly above the liquid outlet channel 1124, and a plurality of leakage holes 711 are provided through the bottom wall of the first groove 71. The outlet of the leakage hole 711 is connected to the liquid outlet channel 1124, so that the waste liquid generated during the detection process can be discharged from the liquid outlet channel 1124 through the leakage hole 711 on the bottom wall of the first groove 71 after flowing out from the inner hole of the actuator 9.

[0070] In order to support the fixed chamber 11, such as Figure 2 and Figure 7 As shown, the fixing device 1 also includes a base 12.

[0071] In some embodiments, such as Figure 7 As shown, the base 12 is generally a trapezoidal shell structure, which includes two parallel trapezoidal sidewalls and a second top wall plate connecting the two trapezoidal sidewalls together. The bottom edges of the two trapezoidal sidewalls and the two ends of the second top wall plate form a rectangular opening.

[0072] It is understood that in some other embodiments, the base 12 may also be a structure of other shapes, as long as it can support the fixing chamber 11, and there are no restrictions here.

[0073] It should be noted that, in this embodiment, to facilitate a compact connection between the fixed chamber 11 and the base 12, such as Figure 2 and Figure 3 As shown, a first clearance groove 1121 is formed between the first top wall plate in the lower housing 112 and the semi-circular side wall plates protruding from both sides of the first top wall plate, and the upper part of the base 12 passes through the first clearance groove 1121.

[0074] To facilitate the discharge of waste liquid generated during the testing process from the fixed chamber 11, the fixed chamber 11 is rotatably mounted on the base 12. Therefore, when discharging waste liquid from the inner hole of the actuator 9, the fixed chamber 11 can be rotated, causing the opening of the inner hole of the actuator 9, fixed within the fixed chamber 11, to tilt downwards, thus facilitating the outflow of waste liquid from the inner hole of the actuator 9. It is understood that because the actuator 9 is fixed within the fixed chamber 11 by the limiting structure, even if the fixed chamber 11 rotates, the actuator 9 within it will not shift.

[0075] Furthermore, the fluorescence penetrant detection line also includes a drive mechanism for driving the fixed chamber 11 to rotate relative to the base 12. In some embodiments, the drive mechanism includes a drive member 6 and a transmission structure, wherein the drive member 6 is capable of driving the transmission structure to achieve the rotation of the fixed chamber 11.

[0076] Optionally, such as Figure 3 , Figure 7 and Figure 8As shown, the transmission structure includes a meshing gear 123 and a rack 1122. The driving component 6 is a motor. The gear 123 is rotatably mounted on the base 12, and the motor shaft of the motor is connected to the gear 123. The rack 1122 is mounted on the lower housing 112 of the fixed chamber 11, and the rack 1122 is an arc-shaped rack. By setting the rack 1122 on the fixed chamber 11 to mesh with the gear 123 on the base 12, not only is the stable support of the base 12 for the fixed chamber 11 achieved, but the stability of the fixed chamber 11 during rotation is also ensured.

[0077] Furthermore, two racks 1122 are provided, respectively located on the lowermost arcuate end faces of the two semicircular sidewalls of the lower housing 112. Correspondingly, two gears 123 are provided, respectively located on the two trapezoidal sidewalls of the base 12. The two gears 123 mesh with the two racks 1122 in a one-to-one correspondence. When the gears 123 rotate, they can drive the racks 1122 to rotate together, thereby enabling the fixed chamber 11 to rotate relative to the base 12. The two gears 123 can be driven by two separate motors or by a single motor. When the two gears 123 are driven by a single motor, the two gears 123 are coaxially connected through a gear shaft, and the motor shaft is connected to the gear shaft via a conveyor belt.

[0078] It is understood that in some other embodiments, the fixed chamber 11 and the base 12 can also be rotatably connected in other ways. For example, a rotating shaft can be provided that passes through the part where the base 12 and the lower housing 112 overlap, and the rotating shaft can be directly driven by the driving member 6. In this way, the base 12 can also support the fixed chamber 11 and the fixed chamber 11 can rotate relative to the base 12. This is not a limitation. Of course, other types of driving mechanisms can also be used to drive the fixed chamber 11 to rotate relative to the base 12. This is not a limitation either.

[0079] To facilitate centralized treatment of waste liquid, the fluorescence penetrant detection line also includes a waste liquid collection device 4, which is used to collect waste liquid flowing out from the waste discharge structure.

[0080] In some embodiments, such as Figure 1 and Figure 9 As shown, in this embodiment, the waste liquid collection device 4 includes a waste liquid collection pipe 41 and a waste liquid collection component 42. The waste liquid collection pipe 41 is disposed on the waste liquid collection component 42 and communicates with the interior of the waste liquid collection component 42. The waste liquid collection pipe 41 is connected to the waste discharge structure, and the waste liquid collection component 42 is provided with an openable and closable waste discharge port. Optionally, the waste liquid collection pipe 41 is generally a T-shaped funnel structure, and the waste liquid collection component 42 is a hollow annular structure. The waste liquid collection pipe 41 is disposed on the waste liquid collection component 42, and the two are internally connected.

[0081] It is understandable that when multiple fixed devices 1 are provided, multiple waste liquid collection pipes 41 can also be provided on the waste liquid collection component 42, and the multiple waste liquid collection pipes 41 are configured one-to-one with the waste discharge structure of the multiple fixed chambers 11. This configuration allows multiple fixed chambers 11 to discharge waste liquid into the waste liquid collection component 42 for convenient unified treatment.

[0082] Furthermore, to facilitate the connection between the waste discharge structure on the fixed device 1 and the waste liquid collection pipe 41 on the waste liquid collection device 4, such as... Figure 7 and Figure 10 As shown, in this embodiment, the base 12 is also provided with a second clearance groove 121 and a third clearance groove 122. The base 12 can be locked onto the waste liquid collection component 42 through the third clearance groove 122. At the same time, the waste liquid collection pipe 41 can pass through the second clearance groove 121 so that its opening for collecting waste liquid is located directly below the liquid outlet channel 1124. Thus, the waste liquid generated during the detection process flows out from the inner hole of the actuator 9 and can finally flow into the waste liquid collection pipe 41 through the leakage hole 711 and the liquid outlet channel 1124.

[0083] It should be noted that the opening of the waste liquid collection pipe 41 for collecting waste liquid is slightly larger than the outlet of the liquid outlet channel 1124, thereby ensuring that all waste liquid discharged from the liquid outlet channel 1124 can flow into the waste liquid collection pipe 41 to avoid waste liquid leakage.

[0084] It is understood that in some other embodiments, the waste liquid collection device 4 may also be of other structures, such as a dedicated waste liquid collection tank, which is connected to the drain outlet on the fixed device 1 by a hose, and can also achieve the function of collecting waste liquid. In this case, there is no need to open the second clearance groove 121 and the third clearance groove 122 on the base 12.

[0085] Furthermore, to facilitate the positioning and fixing of multiple fixing devices 1 in the circumferential direction of the transfer device 3, such as... Figure 1 As shown, in this embodiment, the transfer device 3 is placed inside the waste liquid collection component 42, and multiple fixing devices 1 are arranged in an arc-shaped interval on the waste liquid collection component 42. The working device 2 can be placed on the part of the waste liquid collection component 42 where the fixing devices 1 are not placed. This arrangement not only makes it easier for operators to arrange and position the fixing devices 1, the working device 2, and the transfer device 3, but also makes the structure of the entire fluorescence penetrant detection line very compact, further reducing the footprint.

[0086] Optionally, such as Figure 1 and Figure 11As shown, in this embodiment, the fluorescence permeation detection line also includes a placement platform 5, which is roughly fan-shaped and placed on the outer side of the ring of the waste liquid collection component 42 where the fixing device 1 is not placed. The placement platform 5 has multiple placement slots 51, and the working device 2 is elongated. When the working device 2 is not in use, the multiple working devices 2 can be placed in the multiple placement slots 51 one by one.

[0087] It is understood that in some other embodiments, the placement platform 5 may also have other structures or shapes, as long as it can be used to place the working device 2, and there are no restrictions here.

[0088] Optionally, such as Figure 1 As shown, in this embodiment, the multiple operating devices 2 include a white light observation tube 21, a black light observation tube 22, a cleaning water pipe 23, a hot air pipe 24, an emulsifier pipe 25, a developer pipe 26, and a permeate pipe 27. The white light observation tube 21 and the black light observation tube 22 are connected to an electrical control device; the cleaning water pipe 23 and the hot air pipe 24 are connected to a water and heat control device; the emulsifier pipe 25 is connected to an emulsifier storage tank via a central control cabinet; the developer pipe 26 is connected to a developer storage tank via a central control cabinet; and the permeate pipe 27 is connected to a permeate storage tank via a central control cabinet.

[0089] It is understood that in some other embodiments, the working device 2 may be adaptively increased or decreased according to specific detection requirements, and no limitation is made here.

[0090] Furthermore, the electrical control device, water and heat control device, and central control cabinet are all connected to a computer. The computer can precisely control the amount of material used and parameters, set the working time of each working device 2, and coordinate the testing to achieve automatic production scheduling, thereby improving the automation level of the fluorescence penetrant testing line and reducing labor costs.

[0091] Furthermore, to facilitate the insertion of the working device 2 into the inner hole of the actuator 9 for operation, such as... Figure 2 and Figure 3 As shown, in this embodiment, the fixed chamber 11 is also provided with a detection through hole 1111. Optionally, the detection through hole 1111 is provided on the curved wall panel of the upper shell 111. When the actuator 9 is placed in the receiving chamber, the detection through hole 1111 can communicate with the inner hole of the actuator 9, and then the working device 2 can extend into the inner hole of the actuator 9 through the detection through hole 1111 to perform operations. It can be understood that since the actuator 9 is fixed in the fixed chamber 11 by the limiting structure, it can be ensured that the inner hole of the actuator 9 is always in a directly aligned position with the detection through hole 1111, thereby ensuring the smooth progress of the detection process.

[0092] like Figure 1As shown, in some embodiments, the transfer device 3 is a robotic arm with multiple degrees of rotational freedom. The end of the robotic arm has a gripper, and the electronic control components of the robotic arm are connected to a computer. The computer can then control the robotic arm to selectively grip the working device 2 and move it to the fixed device 1 to sequentially process or inspect the inner hole of the actuator 9. By setting the transfer device 3 as a robotic arm, the automation level of the fluorescence penetrant detection line can be further improved, and labor costs can be reduced.

[0093] It is understood that in some other embodiments, the transfer device 3 may also be other structures, such as a combination of an XYZ three-axis moving module and a gripper, as long as it can realize the fixing and moving of the working device 2, and no limitation is made here.

[0094] The specific operating procedure of the fluorescence penetrant detection line provided in this embodiment is as follows:

[0095] 1. Preparation stage: Place the cleaned actuators 9 into the fixed compartments 11 of the multiple fixed devices 1 respectively, specifically one actuator 9 is placed in one fixed compartment 11.

[0096] 2. Permeation stage: The permeate tube 27 is fixed by the transfer device 3 and moved through the detection through hole 1111 into the inner hole of the actuator 9. The permeate is sprayed by electrostatic spraying under the custom stroke. After the set parameters are completed, the permeate tube 27 is put back into the original position.

[0097] 3. Emulsification stage: If there is an emulsification process, the emulsifier tube 25 is fixed by the transfer device 3 and moved through the detection through hole 1111 to the inner hole of the actuator 9 to spray emulsifier. After completion, the emulsifier tube 25 is returned to its original position.

[0098] 4. Cleaning stage: After the penetration or emulsification time is up, use the transfer device 3 to fix the cleaning water pipe 23, and move the cleaning water pipe 23 through the detection through hole 1111 to extend into the inner hole of the actuator 9 for customized cleaning. After completion, put the cleaning water pipe 23 back in its original position.

[0099] 5. Observation Stage: After cleaning, use the transfer device 3 to fix the black light observation tube 22, and move the black light observation tube 22 through the detection through hole 1111 to the inner hole of the actuator 9 for observation to check if it is clean. After completion, put the black light observation tube 22 back in its original position. If it is clean, proceed to the next step; if not, return to the previous step for cleaning.

[0100] 6. Drying stage: After the inner hole of the actuator 9 is cleaned, the hot air pipe 24 is fixed by the transfer device 3 and moved through the detection through hole 1111 to the inner hole of the actuator 9 for drying. After completion, the hot air pipe 24 is returned to its original position.

[0101] 7. Development stage: After drying, the developing powder tube 26 is fixed by the transfer device 3 and moved to pass through the detection through hole 1111 and extend into the inner hole of the actuator 9. Electrostatic powder is sprayed using the principle of electrostatic spraying. After completion, the developing powder tube 26 is returned to its original position.

[0102] 8. Observation Stage: After powder coating is completed, first, use the transfer device 3 to fix the black light observation tube 22, and move the black light observation tube 22 through the detection through hole 1111 to extend into the inner hole of the actuator 9 for observation and photography. Then, use the transfer device 3 to fix the white light observation tube 21, and move the white light observation tube 21 through the detection through hole 1111 to extend into the inner hole of the actuator 9 for observation and photography. Both times, full-coverage observation and photography of the inner wall are performed, and position information is recorded to facilitate repeated positioning to the designated points on the photographs.

[0103] 9. Evaluation stage: The captured images are marked, evaluated manually according to standards, relevant information is entered into the computer, and an evaluation report is generated.

[0104] 10. Cleaning stage: Use the transfer device 3 to fix the cleaning water pipe 23 and move the cleaning water pipe 23 to clean the entire testing line.

[0105] The above-mentioned operation process 2-10 is a complete testing process for one actuator 9. However, in operation process 2 or 3, when the current actuator 9 is in the permeation or emulsification stage, the transfer device 3 can be controlled to fix the permeate pipe 27 or the emulsifier pipe 25 to perform the permeation or emulsification process on other actuators 9 in the fixed chamber 11 that have not yet been tested. Then, according to the different end times of permeation or emulsification, the subsequent testing stages are completed in sequence.

[0106] In summary, the fluorescence penetrant detection line provided by this utility model has the following advantages:

[0107] I. This fluorescent penetrant detection line arranges multiple fixed devices 1 and multiple working devices 2 around a transfer device 3 at circumferential intervals, allowing multiple working devices 2 to share a single workstation, thereby reducing the footprint of the detection line. Simultaneously, when the actuator 9 in one of the fixed devices 1 is in the penetrant or emulsification stage, the transfer device 3 can be controlled to process or detect the actuators in other fixed devices 1, thus enabling the simultaneous detection of multiple actuators 9 on a single detection line. This not only further reduces the footprint of the detection line but also makes full use of the waiting time during the detection process, improving detection efficiency.

[0108] Second, based on the circular layout of the detection line, the waste liquid collection device 4 is designed as a ring, which not only facilitates the operator in arranging and positioning the fixing device 1, the working device 2 and the transfer device 3, but also makes the structure of the entire fluorescence penetrant detection line very compact, further reducing the footprint.

[0109] Third, the fluorescent penetrant detection line provided by this utility model is a fully automated detection system, which not only reduces labor costs, but also improves the repeatability and stability of the detection line, reduces human error, and enhances the protection of the human body.

[0110] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
