Description

Technical Field

[0001] The invention relates to the technical field of ceramic detection, in particular to a sintered ceramic tube detection device. Background Art

[0002] Ceramic tube is a tubular structure made of high-purity ceramic material with a variety of excellent physical and chemical properties. According to different materials and manufacturing processes, it can be divided into high-purity alumina ceramic tube, boron nitride ceramic tube, corundum ceramic tube, etc. The processing procedures of ceramic products are complicated, and each process may form defects that affect the performance. Therefore, it is necessary to use a test device to detect the defects of ceramic tubes. Non-destructive testing is to use various methods to detect defects inside or on the surface of parts without damaging the ceramic tube, and these defects are often not found or confirmed by visual inspection.

[0003] There are many methods of non-destructive testing, which can be generally divided into three categories: radiation (X-ray, Y-ray) testing, ultrasonic testing and surface testing. Penetrant testing is widely used in non-destructive testing of ceramic tubes, and is mainly divided into fluorescent penetrant testing and color penetrant testing. Penetrant testing uses green fluorescent penetrant liquid or red color penetrant liquid to display the traces of the magnified defect image, so that cracking defects on the surface of the specimen can be detected with the naked eye. The use of fluorescent penetrant is called fluorescent penetrant testing, and the use of red color penetrant is called color penetrant testing. The operating steps of the fluorescent penetrant testing method are as follows:

[0004] 1) Penetration: First, immerse the ceramic tube specimen in the penetrant, or apply the penetrant on the surface of the specimen with a sprayer or brush. If the specimen has cracks, pores and other cracks, the penetrant (fluorescent liquid) will penetrate into it.

[0005] 2) Cleaning: After the penetrant (fluorescent liquid) fully penetrates into the defect, use a cleaning agent or water to wash away the penetrant on the surface of the specimen. Since the cleaning agent cannot penetrate into the cracks and pores where the penetrant remains, the penetrant in the cracks and pores is retained.

[0006] 3) Development: Spray the developer onto the surface of the specimen. The penetrant remaining in the cracks and pores will be absorbed by the developer onto the surface, forming an amplified yellow-green fluorescence or red display mark.

[0007] 4) Observation: The traces displayed by fluorescent penetrant can emit strong fluorescence under ultraviolet light, which is very easy to identify. Very fine defects can be found by naked eye.

[0008] There are also fluorescent penetrant testing devices in the prior art to perform inspection operations on test pieces, such as the patent with authorization announcement number CN219641597U and name "A fluorescent penetrant testing device for non-destructive testing", which includes a supporting mechanism, a spraying mechanism and a removal mechanism. The supporting mechanism includes a bracket and a supporting plate for placing a plate, the supporting plate is connected to the bracket, the spraying mechanism includes a storage box and a spraying assembly, the storage box is located below the supporting plate, the spraying assembly is connected to the storage box, the spraying assembly is used to spray fluorescent penetrant onto the plate, and the removal mechanism is connected to the bracket, and the removal mechanism is used to push excess fluorescent penetrant on the plate into the storage box.

[0009] Another example is the invention patent application with application publication number CN114994068A, entitled A fluorescent penetration detection device with intelligent identification and its detection method, which includes a U-shaped work frame, a workpiece clamping assembly, a fluorescent powder recovery assembly, a height adjustment frame assembly and a turntable adjustment assembly. When in use, the workpiece to be inspected is placed on the conveying roller, and then the conveying motor is started to adjust the conveying roller movement to drive the workpiece to move to a suitable position, the electric clamping rod is started to adjust the workpiece clamping plate to clamp and limit the workpiece, and then the first electric telescopic rod is started to adjust the arc cover to cover the outside of the workpiece, and the water pump is started to spray the fluorescent powder to be sprayed on the outside of the workpiece, and it flows into the side drawer for collection. After the spraying is completed, the electric clamping rod is started to loosen the clamping of the workpiece through the workpiece clamping plate, and then the adjustment motor is started to adjust the turntable rotation, and the darkroom cover is adjusted by the second electric telescopic rod to cover the workpiece to form a darkroom.

[0010] The fluorescent penetrant testing device in the prior art is suitable for testing plate-shaped test pieces. When testing tubular pieces of ceramic tubes, the penetrant (fluorescent liquid) on the outer wall of the ceramic tube cannot be cleaned, and the developer cannot be sprayed on the surface of the ceramic tube, which will affect the detection effect.

[0044] Specifically, an upper box is arranged above the workbench 1, and a frame 10 is installed on the workbench 1 and located inside the upper box. The frame 10 is used for installing relevant operating mechanisms. The frame 10 includes a base 11 and a mounting frame arranged on the base 11. The base 11 is provided with different operating stations in sequence along its length direction. There are at least three operating stations: a feeding station 15, a penetration spraying station 16 and a cleaning and developing station 17. Different detection operations are arranged correspondingly at different stations.

The illumination observation operation can be performed at the cleaning and developing station 17, or an independent illumination observation operation station can be provided for the illumination observation operation.

[0045] In this embodiment, a feeding mechanism 18 is provided at the feeding station 15, a receiving V-shaped groove 12 is provided on the base 11 at the penetration spraying station 16, and a supporting mechanism 13 is provided on the receiving V-shaped groove 12. The supporting mechanism 13 includes a supporting seat 14, and a plurality of supporting seats 14 are arranged in sequence along the length direction of the receiving V-shaped groove 12. The feeding mechanism 18 is arranged on one side of the base 11. During use, the ceramic pipe fittings 2 are first cleaned of dust, scale, etc., and the ceramic pipe fittings 2 are transported to the supporting seat 14 through the feeding mechanism 18. The feeding mechanism 18 can be a pushing cylinder, a manipulator or other structures. This is the prior art and will not be repeated.

[0046] A spraying assembly 19 is provided directly above the penetration spraying station 16. The spraying assembly 19 can spray fluorescent liquid onto the ceramic pipe fitting 2 located on the supporting seat 14, and the excess fluorescent liquid sprayed will flow and be collected in the receiving V-shaped groove 12. When the receiving V-shaped groove 12 is full of fluorescent liquid, the lower half of the ceramic pipe fitting 2 is immersed in the fluorescent liquid in the receiving V-shaped groove 12. In this way, when the fluorescent liquid is sprayed, the upper half of the ceramic pipe fitting 2 is sprayed by the spraying assembly 19, and the lower half is immersed in the fluorescent liquid in the receiving V-shaped groove 12, so that the fluorescent liquid can penetrate into tiny defects.

During this process, the moving operating mechanism 5 cleans and wipes the ceramic tube 2 to wipe off the excess fluorescent liquid on the ceramic tube 2; the second operation stage is the display agent coating operation. After the cleaning and wiping operation is completed, after the ceramic tube 2 is dried, the moving operating mechanism 5 moves along the axial direction of the ceramic tube 2, so that the display agent is evenly coated on the ceramic tube 2.

[0048] In this embodiment, after the ceramic tube 2 completes the display agent coating operation, a searchlight inspection operation is then performed. The searchlight inspection operation in this embodiment is also performed at the cleaning and developing station 17, that is, a searchlight source 6 is installed above the cleaning and developing station 17, and the upper box body has a shading effect. The searchlight source 6 can emit ultraviolet rays to the ceramic tube 2. The searchlight source 6 is preferably a quartz mercury lamp, which is a lamp tube or bulb filled with neon gas. Ultraviolet rays are emitted after the power is turned on. Nickel glass is arranged under the searchlight source 6 to absorb visible light and only allow ultraviolet rays to pass through.

[0049] The sintered ceramic tube detection device provided by the present invention includes a workbench 1 and a frame 10 arranged on the workbench 1. The frame 10 is sequentially provided with a penetration spraying station 16 and a cleaning and developing station 17 along its length direction. The penetration spraying station 16 is provided with a supporting mechanism 13 and a spraying assembly 19. The cleaning and developing station 17 is provided with a clamping mechanism 3 and a moving operating mechanism 5. In this way, during use, the ceramic tube 2 can be transported to the supporting mechanism 13 through the feeding mechanism 18, and the spraying assembly 19 sprays fluorescent liquid on the ceramic tube 2 located on the supporting mechanism 13, so that the fluorescent liquid can penetrate into the tiny defects of the ceramic tube 2. Then, the ceramic tube 2 can be transported to the clamping mechanism 3, and the moving operating mechanism 5 moves along the axial direction of the ceramic tube 2 to wipe and spray the ceramic tube 2, so that the excess fluorescent liquid on the ceramic tube 2 is thoroughly wiped off, and the indicator can be evenly coated on the ceramic tube 2.

[0050] In another embodiment provided by the present invention, preferably, the clamping mechanism 3 includes a rotating clamping assembly 4 and a limiting assembly 30 which are relatively arranged, and the rotating clamping assembly 4 and the limiting assembly 30 are respectively arranged at opposite ends of the cleaning and developing station 17, and the positions of the rotating clamping assembly 4 and the limiting assembly 30 can be adjusted as needed, so that the distance between the rotating clamping assembly 4 and the limiting assembly 30 is set corresponding to the length of the ceramic pipe 2, and the rotating clamping assembly 4 is arranged on the side away from the penetration spraying station 16, and the limiting assembly 30 includes a movable seat 31 and a limiting ring 32 arranged on the movable seat 31, and the radial dimension of the limiting ring 32 is larger than the radial dimension of the ceramic pipe 2, and the movable seat 31 is movably mounted on the base 11, and the movable seat 31 is driven to adjust its position. During use, when the ceramic pipe 2 is transported from the penetration spraying station 16 to the cleaning and developing station 17 by the feeding mechanism, one end of the ceramic pipe 2 is located at the rotating clamping assembly 4, and the rotating clamping assembly 4 clamps the ceramic pipe 2, and the other end of the ceramic pipe 2 is located in the limiting ring 32.

[0051] In another embodiment provided by the present invention, preferably, the rotating clamping assembly 4 includes a clamping seat 40, on which a clamping member 41 and a clamping driving member 42 are provided, a cylindrical mounting cavity 400 is provided at the center position of the clamping seat 40, the cylindrical mounting cavity 400 passes through the clamping seat 40, and an annular groove portion 401 connected to the cylindrical mounting cavity 400 is provided at both ends of the clamping seat 40, and an annular rotating member 402 is provided in the annular groove portion 401. The clamping member 41 includes a clamping mounting body 410 and a clamping member 414. The clamping mounting body 410 can be rotatably mounted in the cylindrical mounting cavity 400. The clamping mounting body 410 is cylindrical, and at least three fan-shaped grooves are arranged in the middle position of the clamping mounting body 410, and the multiple fan-shaped grooves are arranged in sequence along the circumference of the clamping mounting body 410. In this way, the clamping mounting body 410 forms an intermediate mounting body and a connecting ring 419 located at both ends of the intermediate mounting body. The connecting ring 419 is fixedly connected to the annular rotating member 402, so that the clamping mounting body 410 can be rotatably mounted in the cylindrical mounting cavity 400. At the same time, the fan-shaped grooves form at least three radial mounting parts 411 on the middle mounting body, a central channel 413 is arranged at the central position of the central mounting body, and a radial opening 412 is arranged on each radial mounting part 411. The radial opening 412 extends axially through the connecting ring 419, and each radial opening 412 is connected to the central channel 413. If there are four fan-shaped grooves, four radial mounting parts 411 are formed, and radial openings 412 are arranged on the four radial mounting parts 411. The four radial openings 412 and the central channel 413 form an open cavity with a cross-shaped cross section, and the open cavity is for the clamping member 414 to be installed inside.

[0052] The number of the clamping members 414 is consistent with the number of the radial openings 412, that is, a clamping member 414 is installed in each radial opening 412 in a one-to-one correspondence. The clamping member 414 is a strip-shaped structure, a part of the clamping member 414 is located in the opening cavity, and the other part extends out of the opening cavity to form an extended clamping portion. A sliding pin 415 is provided on the clamping member 414, and a sliding limiting groove 416 is provided on the side wall of the radial opening 412. The sliding pin 415 is slidably limited in the sliding limiting groove 416, so that each clamping member 414 can only be driven along the column. In order to facilitate radial movement of the cylindrical mounting cavity 400, a spring member 417 is provided between each clamping member 414 and the side wall of the radial opening 412. The spring member 417 is provided along the radial direction of the cylindrical mounting cavity 400, and a radial mounting plate is installed on the side wall of the radial opening 412. One end of the spring member 417 is connected to the radial mounting plate, and the other end is connected to the clamping member 414. The spring member 417 is arranged as follows: when the spring member 417 is in the initial state, the distance between the clamping members 414 is the smallest, that is, the clamping members 414 are fitted together.

[0053] In another embodiment provided by the present invention, preferably, the clamping driving component 42 includes a driving cylinder 420 and a conical driving body 422, the conical driving body 422 is connected to the piston rod 421 on the driving cylinder 420, an L-shaped connecting seat 423 is arranged at the end of the clamping seat 40, the driving cylinder 420 is installed on the L-shaped connecting seat 423, a through hole for the piston rod 421 to move is arranged on the L-shaped connecting seat 423, the conical driving body 422 is located in the central channel 413 of the open cavity and is connected to the end of the piston rod 421, and the end of the conical driving body connected to the piston rod 421 is the end with a smaller radial dimension, and a pressure bearing 418 is arranged at the end of the clamping member 414 located inside the open cavity through a central axis sleeve, and each pressure bearing 418 is in pressure contact with the conical surface of the conical driving body.

[0054] During operation: in the initial state, the piston rod 421 contacts the pressure bearings 418, at which time the spring members 417 are in the initial state, and the distance between the ends of the clamping members 414 away from the clamping seat 40 is the smallest and they fit together, so that the clamping members 414 can be inserted into the inner wall of the ceramic tube, and there is a gap between the ends of the clamping members 414 located inside the clamping seat 40, which encloses a space surrounding the conical driving body, and then the piston rod 421 is driven by the cylinder 420 to make a recovery movement, and the conical surface of the conical driving body faces the pressure bearings. The bearing 418 is pressed, so that the clamping parts 414 move away from each other along the radial opening 412. During this process, each spring part 417 is pressed and has elasticity until each clamping part 414 presses against the inner wall of the ceramic tube, thereby clamping and fixing the ceramic tube; conversely, when the driving cylinder 420 works to make the piston rod 421 extend, the pressing pressure of the conical surface of the conical driving body on each pressing bearing 418 disappears, and under the elastic force of the spring part 417, the clamping parts 414 move towards each other, thereby loosening the clamping and fixing of the ceramic tube.

[0055] In another preferred embodiment provided by the present invention, the rotary clamping assembly 4 further includes a rotary driving member 43. The rotary driving member 43 includes a rotary driving motor 424 and a transmission member. An L-shaped mounting seat 430 is provided on the clamping seat 40.

The L-shaped mounting seat 430 includes a mounting side plate 431 parallel to the end face of the clamping seat 40 and a connecting side plate 432 perpendicular to the mounting side plate 431. The other end of the connecting side plate 432 is connected to the end face of the clamping seat 40. The mounting side plate 431, the connecting side plate 432 and the end face of the clamping seat 40 form a U-shaped mounting space. The rotary driving motor 424 is mounted on the mounting side plate 431, and the transmission member is mounted in the U-shaped mounting space. The transmission member includes a driving bevel gear 433, a transmission bevel gear 434 and a rotary bevel gear 435 that are sequentially transmission-connected. The driving bevel gear 433 is connected to the driving shaft of the rotary driving motor 424. The transmission bevel gear 434 is rotatably mounted on the connecting side plate 432. The rotary bevel gear 435 is connected to an annular rotating member 402. Since the driving bevel gear 433, the transmission bevel gear 434 and the rotary bevel gear 435 are transmission-connected, when the rotary driving motor 424 drives the driving bevel gear 433 to rotate, the transmission bevel gear 434 and the rotary bevel gear 435 are sequentially driven to rotate, so that the clamping and mounting body 410 and the clamping member 414 located on the clamping and mounting body 410 both rotate. If the clamping member 414 is in a clamping state with respect to the ceramic pipe fitting 2, the rotation of the clamping member 414 can drive the ceramic pipe fitting 2 to rotate as well. Thus, during the cleaning and wiping operation and the application operation of the developer, the ceramic pipe fitting 2 can rotate, enabling the wiping and application of the ceramic pipe fitting 2 without dead angles, avoiding the situation where the ceramic pipe fitting 2 is not wiped or not applied, and improving the detection effect. In this embodiment, a central hole is provided on the rotary bevel gear 435 for the piston rod 421 to pass through.

An annular mounting seat 51 is arranged on one side of the sliding seat 50, and a plurality of radial grooves 510 are arranged on the annular mounting seat 51. The plurality of radial grooves 510 are arranged in sequence and spaced apart along the circumference of the annular mounting seat 51, and a sliding wiping body 52 is arranged in each radial groove 510. The sliding wiping body 52 includes a strip sliding block 520 and a wiping piece 521 arranged on the strip sliding block 520, and the wiping piece 521 is arranged perpendicular to the strip sliding block 520. The inner wall of the wiping piece 521 is an arc-shaped wall, and a flexible wiping structure 522 is arranged on the arc-shaped wall. The flexible wiping structure 522 can wipe the fluorescent liquid on the ceramic tube. The flexible wiping structure 522 can be made of sponge, cotton yarn, etc., and the flexible wiping structure 522 can be detachably installed on the arc-shaped wall, so that when the flexible wiping structure 522 needs to be cleaned or replaced, the flexible wiping structure 522 can be removed from the arc-shaped wall.

[0057] In another embodiment provided by the present invention, preferably, the mobile operating mechanism 5 also includes an annular adjustment plate 53, an outer surface of the annular adjustment plate 53 is provided with an arc-shaped driving handle 530, the arc-shaped driving handle 530 is arranged along the radial direction of the annular adjustment plate 53, and an installation cavity is arranged inside the annular mounting seat 51, the annular adjustment plate 53 can be rotatably installed in the installation cavity, the installation cavity is communicated with each radial groove 510, and the annular adjustment plate 53 is provided with a plurality of arc-shaped limiting grooves 531 along the circumferential direction, and the plurality of arc-shaped limiting grooves 531 are arranged in sequence at intervals along the circumference of the annular adjustment plate 53, the number of the arc-shaped limiting grooves 531 is consistent with the number of the strip sliding blocks 520, and the arc-shaped limiting grooves 531 are arranged as follows: along the circumference of the annular adjustment plate 53, the distance of the arc-shaped limiting grooves 531 from one end to the other end from the center of the annular adjustment plate 53 gradually decreases.

[0058] In another embodiment provided by the present invention, preferably, a limiting column 523 is provided at the bottom of the bar sliding block 520, and the limiting column 523 is slidably restricted in the arc-shaped limiting groove 531. The side of the annular mounting seat 51 is provided with an arc-shaped opening connected to the mounting cavity, and the arc-shaped driving handle 530 extends from the arc-shaped opening. When the arc-shaped driving handle 530 is driven, the annular adjustment plate 53 rotates in the mounting cavity, and can correspondingly drive each bar sliding block 520 to move along the radial groove 510. The inner wall of each wiping member 521 forms a cylindrical wiping cavity 56 corresponding to the ceramic tube. The annular adjustment plate 53 is driven to rotate and can adjust the size of the cylindrical wiping cavity 56, so that the size of the cylindrical wiping cavity 56 is consistent with the size of the ceramic tube, so that the flexible wiping structure 522 fits on the ceramic tube. In this way, the size of the cylindrical wiping cavity 56 is adjustable and can be adapted to cleaning and wiping operations on ceramic tubes of different sizes.

[0059] The number of sliding wiping bodies 52 can be set as needed, such as 3, 4, 5, 6, etc. The adjustment process of the annular adjustment plate 53 is described as follows assuming that there are 6 sliding wiping bodies 52: there are six radial grooves 510 on the annular mounting seat 51, and they are arranged at equal intervals along the circumference of the annular mounting seat 51. There are also six arc-shaped limiting grooves 531 on the annular adjustment plate 53. The strip sliding blocks 520 of the sliding wiping body 52 are slidably connected in the radial grooves 510. The limiting columns 523 at the bottom of each strip sliding block 520 are slidably connected in the arc-shaped limiting grooves 531 one by one. During the rotation of the annular adjustment plate 53, there is always a part of the arc-shaped limiting groove 531 corresponding to the radial groove 510 and connected to the radial groove 510. The arc-shaped limiting groove 531 here is called the connection driving groove 531. When the annular adjustment plate 53 rotates in the first direction, the distance between the connecting driving part of the arc-shaped limiting groove 531 and the center of the cylindrical wiping cavity 56 gradually increases, and the wiping piece 521 and the strip sliding block 520 both move away from the center position of the cylindrical wiping cavity 56. At this time, the wiping piece 521 is in a dispersed state, and the size of the cylindrical wiping cavity 56 becomes larger, which can facilitate the insertion of the ceramic tube into the cylindrical wiping cavity 56; on the contrary, when the annular adjustment plate 53 rotates in the second direction (the direction opposite to the first direction), the distance between the connecting driving part of the arc-shaped limiting groove 531 and the center of the central cleaning cavity gradually decreases, and the wiping piece 521 and the strip sliding block 520 both move towards the center position of the central cleaning cavity until the flexible wiping structure 522 fits on the ceramic tube. At this time, the wiping piece 521 is in a fitted wiping state.

[0060] In another embodiment provided by the present invention, preferably, the mobile operating mechanism 5 also includes a driving member 54 arranged on the sliding seat 50, and the arc-shaped driving handle 530 can be driven by the driving member 54 to rotate, so that the annular adjustment plate 53 rotates. For example, the driving member 54 can be a cylinder. This is a prior art and will not be elaborated.

[0061] In order to improve the cleaning and wiping effect of the ceramic tube, in another embodiment provided by the present invention, a flexible wiping structure 522 is provided on the curved wall of a part of the wiping piece 521, and a water outlet hole 524 is provided on the other part of the wiping piece 521. A water inlet channel is provided inside the sliding wiping body 52, and a connecting port is provided on the sliding wiping body 52, which is connected to the water pipe. In this way, during use, a small amount of water can be sprayed onto the ceramic tube 2 through the water outlet hole 524, thereby facilitating wiping.

[0062] At the same time, the arc-shaped limiting groove 531 includes a first arc-shaped groove 532 and a second arc-shaped groove 533. The first arc-shaped groove 532 corresponds to the wiping piece 521 provided with a flexible wiping structure 522, and the second arc-shaped groove 533 corresponds to the wiping piece 521 provided with a water outlet hole 524. Along the circumference of the annular adjustment plate 53, the second arc-shaped groove 533 is coaxially arranged with the annular adjustment plate 53, and along the circumference of the annular adjustment plate 53, the distance from one end of the first arc-shaped groove 532 to the other end from the center of the annular adjustment plate 53 gradually decreases, so that during the adjustment process: when the annular adjustment plate 53 rotates, the wiping piece 521 corresponding to the second arc-shaped groove 533 does not move, but the wiping piece 521 corresponding to the first arc-shaped groove 532 521 will move. For example, when the annular adjustment plate 53 rotates in the first direction, the distance between the connecting portion of the second arc groove 533 and the center of the central cleaning chamber remains unchanged, and the distance between the connecting portion of the first arc groove 532 and the center of the central cleaning chamber gradually increases, so that the wiping member 521 provided with the flexible wiping structure 522 moves away from the center position of the cylindrical wiping chamber 56. When the annular adjustment plate 53 rotates in the second direction, the distance between the connecting portion of the second arc groove 533 and the center of the central cleaning chamber remains unchanged, and the distance between the connecting portion of the first arc groove 532 and the center of the central cleaning chamber gradually decreases, so that the wiping member 521 provided with the flexible wiping structure 522 moves toward the center position of the cylindrical wiping chamber 56. The advantage of such a configuration is that the wiping piece 521 provided with the water outlet hole 524 always maintains a certain distance from the ceramic pipe fitting 2, so that a small amount of water required for cleaning can be sprayed onto the ceramic pipe fitting 2, and the position of the wiping piece 521 provided with the flexible wiping structure 522 can be adjusted, so that the flexible wiping piece 521 can fit on the ceramic pipe fitting 2 to wipe the ceramic pipe fitting 2.

[0063] In another embodiment provided by the present invention, preferably, an annular spray seat 55 is arranged on the other side of the sliding seat 50, and the annular spray seat 55 and the annular mounting seat 51 are respectively arranged on the opposite sides of the sliding seat 50, and the radial dimension of the annular spray seat 55 is larger than the radial dimension of the ceramic tube, and a plurality of spray members 550 are arranged inside the annular spray seat 55, and an annular cavity is arranged inside the annular spray seat 55, and a spray interface connected to the annular cavity is arranged on the annular spray seat 55, and the spray interface is connected to the display agent delivery pipe, so that the display agent can be evenly sprayed onto the ceramic tube through the display agent delivery pipe, the annular cavity and the plurality of spray members 550.

[0064] In this embodiment, in actual use, the operation steps are as follows:

[0065] In the first step, the dust, scale, etc. of the ceramic pipe fitting 2 are cleaned up, and the inspection station is placed on the feeding mechanism 18 by a manipulator or other feeding device, and then the ceramic pipe fitting 2 is pushed from the feeding mechanism 18 to the supporting mechanism 13 by the feeding mechanism. In this way, the ceramic pipe fitting 2 is at the penetration spraying station 16, and the spraying assembly 19 sprays fluorescent liquid on the ceramic pipe fitting 2 located on the supporting mechanism 13, and the fluorescent liquid penetrates into the tiny defects of the ceramic pipe fitting 2;

[0066] In the second step, after the fluorescent liquid spraying operation is completed, the ceramic tube 2 is transported to the cleaning and imaging station 17 through the feeding mechanism. During this process, the ceramic tube 2 passes through the central cleaning cavity, so that the wiper 521 surrounds the ceramic tube 2. One end of the ceramic tube corresponds to the rotating clamping assembly 4. At this time, each clamping member 414 is in a retracted state so that it can be inserted into the inner wall of the ceramic tube. Then, the driving cylinder 420 is driven to perform a contraction movement so that the clamping members 414 perform a separation movement along the radial opening 412 to separate from each other until each clamping member 414 is pressed against the inner wall of the ceramic tube, thereby achieving the clamping and fixing of the ceramic tube. At this time, the other end of the ceramic tube 2 is located on the limiting ring 32 of the limiting assembly 30.

[0067] In the third step, the arc-shaped driving handle 530 and the annular adjustment plate 53 are driven to rotate by the driving component 54, so that the wiping member 521 provided with the flexible wiping structure 522 moves toward the direction close to the ceramic tube 2 until the flexible wiping structure 522 is attached to the ceramic tube 2. Then, the sliding seat 50 is driven by the driving unit to move along the axial direction of the ceramic tube, and the flexible wiping structure 522 wipes the fluorescent liquid on the ceramic tube 2, so that the excess fluorescent liquid on the ceramic tube 2 is wiped off.

[0068] During this process, the rotating drive member 43 works to cause the clamping member 414 to rotate, and the rotation of the clamping member 414 also drives the ceramic tube to rotate. In this way, during the cleaning and wiping operation, the ceramic tube can also rotate, so that the flexible wiping structure 522 can wipe the ceramic tube without dead angles, avoiding the situation where the ceramic tube is not wiped.

[0069] During this process, a small amount of water can be sprayed onto the ceramic tube through the wiping piece 521 provided with the water outlet hole 524, so as to facilitate wiping and improve the wiping effect.

[0070] In the fourth step, after the cleaning and wiping operation is completed, when the ceramic tube 2 is dry, the driving component 54 drives the arc-shaped driving handle 530 and the annular adjustment plate 53 to rotate, so that the wiping member 521 provided with the flexible wiping structure 522 moves in the direction away from the ceramic tube 2, and then the sliding seat 50 is driven by the driving unit to move along the axial direction of the ceramic tube. In this process, the display agent is evenly sprayed onto the ceramic tube through the annular spray seat 55 and multiple spray members 550, and the rotating driving member 43 works to rotate the clamping member 414 and the ceramic tube, so that the display agent is evenly sprayed onto the ceramic tube.

[0071] In the fifth step, after the ceramic pipe 2 has completed the display agent coating operation, a searchlight inspection operation is then performed. The searchlight source 6 emits ultraviolet rays to the ceramic pipe 2. The display traces of the fluorescent liquid emit strong fluorescence under the ultraviolet rays. The defects of the ceramic pipe 2 are detected by observing the fluorescence.

[0072] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
