Description

Technical Field

[0001] The present invention relates to the technical field of bar flaw detection, in particular to a bar flaw detector system. Background Art

[0002] After steel production is completed, it needs to be inspected using a flaw detector. A flaw detector is a device used to detect internal and surface defects in steel. It is a type of non-destructive testing technology and is mainly used to check the quality and safety of steel. The flaw detector uses physical properties to detect various defects inside or on the surface of the material, such as cracks, pores, inclusions, etc., without damaging the performance of the steel, and determines their location, size, shape and type. This technology is crucial to ensuring the quality and safety of steel. It is widely used in industrial fields such as shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation and construction, and is an indispensable detection tool in industrial production.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figures 1-8 As shown, one embodiment of the present invention provides a bar flaw detector system, comprising a bar carrying platform, a bar picking device, a flaw detection device, a bar transfer device, and a bar receiving device. The bar carrying platform, the bar picking device, the flaw detection device, and the bar receiving device are sequentially arranged along a first direction, and the bars are placed on the bar carrying platform extending along a second direction. The bar picking device comprises:

[0041] At least two movable guide rail platforms arranged along the second direction; the two movable guide rail platforms are respectively located on both sides of the bar supporting platform, and the movable guide rail platforms can move along the first direction to drive the bar toward or away from the flaw detection device, and a load-bearing wheel mechanism for carrying the bar is installed on the table of each movable guide rail platform;

[0042] The centering clamping mechanism includes two movable clamping structures, which are respectively mounted on two movable guide rail platforms. The two movable clamping structures cooperate to clamp the two ends of the bar;

[0043] A rotating driving mechanism is installed on one of the moving rail platforms, and is used to drive the bar between the two moving clamping structures to rotate around its own axis.

[0044] The bar transfer device includes at least two bar transfer mechanisms 4 arranged along the second direction and located between the two moving rail platforms. The bar transfer mechanisms 4 are used to receive the bar after flaw detection and transfer the bar to the bar receiving device.

[0045] In this embodiment, when the bar is detected, the moving rail platform first moves towards the bar carrying table to the clamping station. At this time, the bar to be detected on the clamping station is located between the two moving clamping structures, and the bar on the clamping station falls on the carrying wheel mechanism. Then, the two moving clamping structures cooperate to clamp the two ends of the bar to be detected. The rotating driving mechanism drives the bar to be detected between the two moving clamping structures to rotate around its own axis. Then, the moving rail platform drives the bar to be detected to move towards the flaw detection device until it moves to the flaw detection station. At this time, the bar to be detected is still rotating around its axis. The flaw detection mechanism in the flaw detection device reciprocates along the second direction to detect different positions of the bar to be detected. After the flaw detection is completed, the moving rail platform moves towards the bar carrying table to the unloading station, so that the bar moves above the bar transfer device. Then, the rotating driving mechanism stops working and the two moving clamping structures release the bar. The bar falls on the bar transfer device, and the bar transfer device transfers the bar to the bar receiving device. Then, the moving rail platform continues to move towards the bar carrying table until it moves to the clamping station again for the next flaw detection.

[0046] Compared with the existing self-rotating bar flaw detection machine, the bar flaw detection machine system has at least the following advantages:

[0047] First, the loading and unloading process is simpler and faster, and the material changing efficiency is improved.

[0048] Second, the bar receiving device with loading function can drive the bar to rotate, replacing the traditional bar rotating roller system. The system has higher integration, and does not need to set up a bar rotating roller system, saving cost.

[0049] Third, the bar receiving device can receive the bar and also buffer the bar during unloading, avoiding large abnormal noise during bar unloading, and protecting the bar.

[0050] In this embodiment, the first direction is from the bar carrying table to the flaw detection device, and the second direction is the length direction of the flaw detection device, or the moving direction of the flaw detection mechanism in the flaw detection device.

[0051] As a preferred embodiment, as shown in Figure 1 The mobile guide rail platform, the bar material bearing table and the flaw detection device are arranged on the upper surface of the base 1. The mobile guide rail platform is provided with three, which are arranged in sequence from left to right. The flaw detection device is located in front of the three mobile guide rail platforms. The bar material transfer device is provided with two, which are arranged in the space between the adjacent two mobile guide rail platforms.

[0052] Further, the mobile guide rail platform comprises a bearing seat, an industrial guide rail, a sliding table and a push cylinder 14. The bearing seat is arranged on the base 1. The industrial guide rail is provided with two, which are arranged on the bearing seat and perpendicular to the flaw detection device. At least one sliding block is slidingly installed on the industrial guide rail. The sliding table is fixedly installed on the sliding block of the industrial guide rail. The push cylinder 14 is arranged on the back of the bearing seat. The shell of the push cylinder 14 is fixedly installed on the bearing seat. The rod end of the push cylinder 14 is fixedly connected with the sliding table.

[0053] When the push cylinder 14 is elongated, the push cylinder 14 pushes the sliding table to move along the industrial guide rail towards the flaw detection device. When the push cylinder 14 is shortened, the push cylinder 14 pulls the sliding table to move along the industrial guide rail away from the flaw detection device.

[0054] It should be noted that the industrial guide rail is provided with two limit switches, i.e. a first limit switch and a second limit switch. When the push cylinder 14 pulls the sliding table to move along the industrial guide rail away from the flaw detection device to the clamping station, the first limit switch sends a signal to the control box 2, indicating that the sliding table has reached the first limit position. The control box 2 controls the push cylinder 14 to pause work, in order to prepare to clamp the bar material on the bar material bearing table. When the push cylinder 14 pushes the sliding table to move along the industrial guide rail towards the flaw detection device to the flaw detection station, the second limit switch sends a signal to the control box 2, indicating that the sliding table has reached the second limit position. The control box 2 controls the push cylinder 14 to pause work, in order to prepare for flaw detection work.

[0055] Preferably, considering that if only two mobile clamping structures are used to clamp the bar material, the load on the mobile clamping structure is too large. Therefore, at least one set of bearing wheel mechanism is installed on the table top of the sliding table of the three mobile guide rail platforms, as shown in Figure 8As shown, the bearing wheel mechanism comprises two guide wheel members arranged along the moving direction of the sliding table. The guide wheel member comprises a door-shaped frame 17, a roller 15 and an axle 16. The two door-shaped frames 17 are installed upside down on the table top of the sliding table. The axle 16 is installed on the top of the door-shaped frame 17, and the axial direction of the axle 16 is the same as the axial direction of the bar. At least one roller 15 is rotatably installed on the axle 16. The bar is carried by the bearing wheel mechanism, and the weight of the bar is borne by the bearing wheel mechanism. Therefore, the two moving clamping structures only need to cooperate to clamp the bar, and do not need to bear the weight of the bar. When the bar rotates, the bar will rotate together with the roller 15. The friction between the bar and the roller 15 is rolling friction, and the friction is small.

[0056] For example, two bearings are coaxially arranged on the axle 16, and a roller 15 is sleeved on the outer ring of the bearing, that is, two rollers 15 are rotatably installed on each axle 16. The bar is placed between the rollers 15 of the two guide wheel members.

[0057] In this embodiment, for the convenience of description, Figure 1 The leftmost moving guide rail platform is named as the first moving guide rail platform, the middle moving guide rail platform is named as the second moving guide rail platform, and the rightmost moving guide rail platform is named as the third moving guide rail platform.

[0058] As shown in the drawings, Figure 1 One moving clamping structure is installed on the sliding table of the first moving guide rail platform, and the other moving clamping structure is installed on the sliding table of the second moving guide rail platform. For the convenience of distinction, the left moving clamping structure is named as the first moving clamping structure, and the right moving clamping structure is named as the second moving clamping structure.

[0059] As shown in the drawings, Figure 3 The first moving clamping structure comprises a first guide rail 903, a first sliding block 904, a first fixed seat 905, a first cylinder 906 and a first sleeve 907. The first guide rail 903 is fixedly installed on the sliding table of the first moving guide rail platform, and the first guide rail 903 is arranged in the left-right direction. The first sliding block 904 is slidably installed on the first guide rail 903. The first fixed seat 905 is in the shape of an L-shaped plate, which has a bottom plate and a vertical plate connected together. The bottom plate is fixedly installed on the first sliding block 904. The first sleeve 907 is rotatably installed on the right side surface of the vertical plate. A first fixed plate is arranged on the left side of the first guide rail 903, and the first fixed plate is fixedly installed on the sliding table of the first moving guide rail platform. The first cylinder 906 is fixedly installed on the first fixed plate, and the cylinder end of the first cylinder 906 is fixedly connected with the left end surface of the first fixed seat 905.

[0060] It should be noted that the first sleeve 907 is in the shape of a cylinder, and the inner diameter of the first sleeve 907 is greater than the outer diameter of the bar, so that the end of the bar can extend into the first sleeve 907.

[0061] Further, the rotating driving mechanism is installed on the sliding table of the first moving guide rail platform, and comprises a second motor 902, a speed reducer 910, a driving pulley, a driven pulley 908 and a transmission belt 909. The driven pulley 908 is sleeved on the first sleeve 907, the driving pulley is installed on the output end of the speed reducer 910, the driving pulley and the driven pulley 908 are transmissionally connected through the transmission belt 909, and the output end of the second motor 902 is connected with the input end of the speed reducer 910. The second motor 902 provides power to drive the driving pulley to rotate, the driving pulley drives the driven pulley 908 to rotate through the transmission belt 909, and finally the first sleeve 907 is driven to rotate.

[0062] In the embodiment, as shown in Figure 4 , the second moving clamping structure comprises a second guide rail 133, a second sliding block 134, a second air cylinder 135, a second fixed base 136, a second fixed plate 132 and a second sleeve 137. The second guide rail 133 is installed on the sliding table of the third moving guide rail platform, the second sliding block 134 is slidingly installed on the second guide rail 133, the bottom plate of the second fixed base 136 is fixedly installed on the second sliding block 134, the second sleeve 137 is rotationally installed on the vertical plate of the second fixed base 136, the second fixed plate 132 is located on the right side of the second guide rail 133 and is fixed to the sliding table of the third moving guide rail platform, the second air cylinder 135 is fixedly installed on the second fixed plate 132, and the cylinder end of the second air cylinder 135 is fixed to the right side surface of the second fixed base 136.

[0063] When taking out the bar, the control box 2 controls the pushing air cylinders 14 of the three moving guide rail platforms to be shortened at the same time to pull the three sliding tables to move towards the bar carrying table at the same time until they move to the clamping position. At this time, the bar at the clamping position is just located between the first sleeve 907 and the second sleeve 137. Then the control box 2 controls the first air cylinder 906 and the second air cylinder 135 to work at the same time, and the first air cylinder 906 and the second air cylinder 135 are elongated by a fixed distance to make the first sleeve 907 and the second sleeve 137 close to each other, so as to clamp the two ends of the bar. The two ends of the bar are tightly attached to the inner walls of the first sleeve 907 and the second sleeve 137 respectively. Then the control box 2 controls the second motor 902 to work, the second motor 902 drives the speed reducer 910 to drive the driving pulley to rotate, the driving pulley drives the driven pulley 908 to rotate through the transmission belt 909, and finally the first sleeve 907 is driven to rotate. In this way, the bar rotates with the rotation of the first sleeve 907. When detecting defects, the bar rotates around its own axis without stopping, so as to facilitate the detection of the detection device, and the bar rotating roller system does not need to be set again, thereby saving cost and facilitating the feeding and discharging.

[0064] As a preferred embodiment, as shown in Figure 1 and Figure 2As shown, there are two bar transfer mechanisms 4, wherein one bar transfer mechanism 4 is located between the first movable guide rail platform and the second movable guide rail platform, and the other bar transfer mechanism 4 is located between the second movable guide rail platform and the third movable guide rail platform. The two bar transfer mechanisms 4 are arranged along the length direction of the bar. Specifically, the bar transfer mechanism 4 is as shown in FIG. Figure 5 As shown, it includes a column 401, two telescopic members, a top plate 404, and a bent plate 405. The two telescopic members are vertically mounted on the column 401 and arranged in a direction perpendicular to the rod. The ends of the top plate 404 are hinged to the top ends of the two telescopic members respectively. The bent plate 405 is mounted on the top of the top plate 404 to support the rod and prevent it from rolling off.

[0065] Among them, one telescopic part is an electric cylinder 402, and the other telescopic part is an electric telescopic rod 403. The electric telescopic rod 403 is closer to the flaw detection device, while the electric cylinder 402 is closer to the bar bearing platform.

[0066] Thus, when the three movable guide rail platforms move toward the bar loading platform to the unloading station, the bars, after flaw detection, are just above the bar transfer mechanism 4. Subsequently, the rotary drive mechanism stops working and the two movable clamping structures release the bars, causing the bars to fall onto the bent plate 405. Subsequently, the electric cylinder 402 and the electric telescopic rod 403 extend simultaneously to raise the height of the bars, so that the height of the bars exceeds the bar receiving device. Then, the electric telescopic rod 403 stops working and no longer extends, while the electric cylinder 402 continues to lift the fixed height to change the tilt angle of the top plate 404, causing the top plate 404 to tilt toward the flaw detection device to a certain degree, making it difficult for the bent plate 405 to restrain the bars. The bars then slide out of the bent plate 405 and fall onto the bar receiving device.

[0067] Exemplarily, the bent plate 405 is a U-shaped plate or a V-shaped plate.

[0068] In addition, there is no specific limit on the number of the rod transfer mechanisms 4, which is determined according to the weight of the rods. When the rods are heavy, more rods are provided, and when the rods are light, fewer rods are provided.

[0069] In this embodiment, the bar receiving device includes at least two bar receiving mechanisms 5, which are arranged along the length of the flaw detection device and located in front of the flaw detection device. Specifically, the bar receiving mechanism 5 includes a base plate 501, a vertical rod 502, a top rod 503, a lifting block 504, an elastic member, and a contact plate 507. The vertical rod 502 is vertically arranged on the base plate 501, and one end of the top rod 503 is connected to the vertical rod 502, and its other end points to the bar support platform. The height of the top rod 503 gradually decreases from the bar support platform to the flaw detection device, that is, the upper surface of the top rod 503 is connected to the upper surface of the vertical rod 502, and the angle formed between the upper surface of the top rod 503 and the upper surface of the vertical rod 502 is obtuse.

[0070] Further, the lifting block 504 is slidingly installed on the vertical rod 502, and the elastic member is arranged between the bottom plate 501 and the lifting block 504, for providing buffering for the lifting block 504. The contact plate 507 is vertically installed on the upper surface of the lifting block 504, the top end of the contact plate 507 is higher than the top rod 503, and the vertical rod 502 away from the top rod 503 forms a containing space between the vertical rod 502 and the contact plate 507 for containing the bar.

[0071] It should be noted that the distance between the end of the top rod 503 pointing to the bar carrying table and the bar transfer mechanism 4 is very close, so as to ensure that the bar on the bar transfer mechanism 4 can smoothly roll onto the top rod 503. In addition, the top rod 503 is higher than the moving clamping mechanism, so as to avoid blocking the movement of the bar.

[0072] After the bar on the bar transfer mechanism 4 rolls onto the top rod 503, since the height of the end of the top rod 503 close to the bar transfer mechanism 4 to the other end gradually decreases, the bar rolls along the top rod 503, and then is blocked by the upper half of the contact plate 507. The impact force of the bar is offset by the contact plate 507, and then the bar falls into the receiving space and acts on the lifting block 504. Since the weight of the lifting block 504 is increased, the elastic member is compressed, and the elastic member offsets the last kinetic energy of the bar. In this way, when the bar is discharged, the impact force of the bar is small, the bar will not produce a large abnormal sound, and will not produce a violent impact, thereby protecting the bar.

[0073] That is, the bar receiving device has the function of receiving the bar, and can also buffer the bar during discharging, so as to avoid the bar producing a large abnormal sound during discharging, and to protect the bar.

[0074] Moreover, the electric cylinder 402 and the electric telescopic rod 403 synchronously lift the bar until the bar passes through the top rod 503, at this time the bar is slightly higher than the top rod 503, and then the electric cylinder 402 continues to lift the bar so that the bar slides onto the top rod 503. Since the height difference between the bar and the top rod 503 at this time is relatively small, the kinetic energy of the bar is limited, and the impact force generated by the bar is also very limited, thereby ensuring that the bar can be discharged quietly, and the noise generated during the discharging process is small, and the surface of the bar will not be damaged due to violent impact. That is, since the actual falling height of the bar is small, the kinetic energy of the bar during falling is small.

[0075] The bar rolls along the top rod 503 and is blocked by the upper half of the contact plate 507, so that the impact force of the bar is further offset. After the bar falls into the receiving space, the elastic potential energy of the elastic member is used to offset the last kinetic energy of the bar.

[0076] Exemplarily, the contact plate 507 is a metal elastic plate, for example, a stainless steel plate, a copper plate, etc. After the rod is blocked by the contact plate 507, the contact plate 507 itself has elasticity, thereby playing a buffering role to a certain extent, offsetting the impact force of the rod by using the elasticity of the contact plate 507 itself, so that the rod is quickly stabilized, and noise can also be reduced.

[0077] In addition, it should be noted that the rod falling into the receiving space will eventually fall onto the upper surface of the lifting block 504. Under the action of the gravity of the rod, the lifting block 504 moves downward, and the elastic member is slowly compressed due to the presence of the elastic member. The elastic member plays a role of providing a buffer to offset the impact force generated when the rod falls, so that the lifting block 504 can slowly move downward.

[0078] As a specific embodiment, as shown in Figure 5 and Figure 6 , the side surface of the vertical rod 502 is provided with a sliding hole 505 in a strip shape and extending along the height direction of the vertical rod 502. The sliding hole 505 divides the lower half of the vertical rod 502 into two parts, that is, the vertical rod 502 is in a U-shaped rod. A circular rod is vertically arranged between the upper surface of the bottom plate 501 and the inner top wall of the sliding hole 505. The elastic member is a spring 506, which is sleeved outside the circular rod. Figure 7 Further, as shown in , the upper surface of the lifting block 504 is provided with a rectangular insertion hole and a through hole for the circular rod to pass through.

[0079] In order to facilitate the installation and subsequent disassembly of the rod receiving mechanism 5, preferably, the bottom end side of the circular rod has an external thread, and a threaded hole is formed in the upper surface of the bottom plate 501. The lower surface of the vertical rod 502 is provided with bolt holes on both sides, and the bottom plate 501 is provided with counterbores corresponding to the bolt holes on the lower surface of the vertical rod 502. During assembly, first, the circular rod is screwed into the threaded hole in the upper surface of the bottom plate 501, then one side of the bottom of the vertical rod 502 is inserted into the insertion hole of the lifting block 504, so that the lifting block 504 is slidingly assembled to the vertical rod 502, and the lifting block 504 is pushed towards the height direction of the vertical rod 502, so that the upper surface of the lifting block 504 is in close contact with the inner top wall of the sliding hole 505. Then, the spring 506 is sleeved outside the circular rod, and then the vertical rod 502 and the lifting block 504 are placed above the bottom plate 501 and the through hole on the lifting block 504 is aligned with the circular rod. Then, the vertical rod 502 and the lifting block 504 are slowly moved downward, so that the circular rod passes through the through hole on the lifting block 504, until the lower surface of the vertical rod 502 is in close contact with the upper surface of the bottom plate 501, and the bolt holes on the lower surface of the vertical rod 502 are aligned with the counterbores on the bottom plate 501. Finally, the vertical rod 502 and the bottom plate 501 are fixed by using countersunk head bolts.

[0080] As a preferred embodiment, in order to further improve the anti-impact ability of the contact plate 507. In this embodiment, two support members are mounted on the lifting block 504, the support member includes a corresponding support plate 509 and an extension rod 508, the extension rod 508 is arranged on the end face of the lifting block 504 away from the top rod 503, and is perpendicular to the contact plate 507, one end of the support plate 509 is connected with the end of the extension rod 508 away from the lifting block 504, and the other end abuts on the contact plate 507, and the included angle formed between the support plate 509 and the extension rod 508 is an acute angle. The two support members are arranged along the width direction of the lifting block 504.

[0081] Preferably, the support plate 509 is a metal elastic plate.

[0082] In this way, when the contact plate 507 is impacted by the bar, the contact plate 507 bends outwardly, and since the support plate 509 always supports the contact plate 507, the impact force that the contact plate 507 can withstand is greatly improved, and the contact plate 507 will not tilt outwardly too much, so as to ensure that the bending degree of the contact plate 507 is within a specified range, thereby ensuring that the contact plate 507 can completely block the bar, avoiding the bar falling into the unloading area beyond the contact plate 507, and improving the safety during the receiving of the bar.

[0083] It should be noted that the end of the support plate 509 in contact with the outer side surface of the contact plate 507 is connected with a cylinder, and the cylinder is in sliding contact with the outer side surface of the contact plate 507.

[0084] As an optional embodiment, in order to improve the anti-impact ability of the contact plate 507, a plurality of contact plates 507 can be arranged, and the plurality of contact plates 507 are arranged in sequence along the length direction of the top rod 503 on the lifting block 504.

[0085] It should be noted that, when the bars in the receiving space are not taken away in time, resulting in a large number of bars accumulated in the receiving space, at this time, the sum of the weight of the lifting block 504 and the bars in the receiving space exceeds the load bearing capacity of the spring 506, and the spring 506 bears a load exceeding its designed load bearing capacity, which will cause the spring 506 to be permanently deformed or broken. In order to avoid such problems, preferably, as shown in Figure 6 and Figure 7 An auxiliary block 510 is inserted between the two extension rods 508, the auxiliary block 510 has an I-shaped cross section, the two side surfaces thereof are respectively provided with a clamping groove matched with the extension rod 508, the auxiliary block 510 is a rubber block, and the lower surface of the auxiliary block 510 is lower than the lifting block 504. When the lifting block 504 falls, the auxiliary block 510 is in contact with the bottom plate 501 earlier than the lifting block 504.

[0086] When the sum of the weight of the bars in the receiving space is added to the lifting block 504 and exceeds the load borne by the spring 506, the lifting block 504 drives the auxiliary block 510 to move downward together, and the spring 506 is gradually compressed. Before the spring 506 is compressed to the limit state, the auxiliary block 510 has already contacted the bottom plate 501, at which time most of the force acts on the auxiliary block 510, so as to ensure that the force borne by the spring 506 does not exceed its load, thereby ensuring that the spring 506 will not be permanently deformed or broken, and improving its service life. Moreover, the double buffering of the spring 506 plus the auxiliary block 510 can greatly improve the carrying capacity of the bar receiving mechanism 5, and more bars can be carried.

[0087] It should be noted that the length of the auxiliary block 510 can be reasonably set according to actual conditions. For example, when the depth of the receiving space is large and the number of bars that can be accommodated is large, the length of the auxiliary block 510 is appropriately increased, and vice versa.

[0088] In the embodiment, the first moving guide rail platform includes a first bearing seat 8, a first industrial guide rail 801, a first sliding table 9, and a first push air cylinder 14.

The second moving guide rail platform includes a second bearing seat 10, a second industrial guide rail 101, a second sliding table 11, and a second push air cylinder 14. The second bearing wheel mechanism 111 is arranged on the table surface of the second sliding table 11.

[0090] In the embodiment, the flaw detection device includes a linear module mechanism 3 and a flaw detection mechanism.

As shown in Figure 1 and Figure 2As shown, the straight line module mechanism 3 comprises a long strip-shaped bearing box, a tooth plate 301, a gear, a walking plate and a walking motor 302. The tooth plate 301 is installed in the bearing box, the walking plate is slidingly installed on the top of the bearing box, the gear is engaged with the tooth plate 301, the walking motor 302 is installed on the top of the walking plate, and the output end of the walking motor 302 is connected with the gear. A fixing frame 303 is installed on the walking plate, and the flaw detection mechanism is installed on the top of the fixing frame 303. The walking motor 302 drives the gear to rotate, and the gear is engaged with the tooth plate 301, so that the walking plate moves along the length direction of the tooth plate 301, i.e. moves left and right, and finally drives the flaw detection mechanism to move back and forth to detect the rod which is rotating continuously.

[0091] It should be noted that the flaw detection mechanism comprises an ultrasonic flaw detection mechanism and an electromagnetic induction flaw detection mechanism.

[0092] As an optional embodiment, the rod bearing table comprises a first bearing plate 6 and a second bearing plate 7 which are vertically installed on the base 1.

A stopper is arranged at the end of the first bearing plate 6 and the second bearing plate 7 close to the flaw detection device, and the stopper is used to stop the rods and prevent the rods from continuing to advance.

[0093] It should be noted that when the rod flaw detector is preparing, the rods can be placed on the first bearing plate 6 and the second bearing plate 7 by using manual or gantry robot, and the rods are ensured to be close to each other. After the rod at the clamping station is removed, the next rod is moved to the clamping station by using manual or gantry robot, and the above steps are sequentially repeated until all the rods on the rod bearing table are detected.

[0094] As another optional embodiment, the method of moving the guide rail platform by one step after taking out one rod can be used for loading.
