DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides a bar flaw detector system, including a bar bearing platform, a bar picking device, a flaw detection device, a bar transfer device and a bar receiving device, wherein the bar bearing platform, the bar picking device, the flaw detection device and the bar receiving device are sequentially arranged along a first direction, and the bar is placed on the bar bearing platform extending along a second direction; wherein the bar picking device includes:

[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 bearing platform, the movable guide rail platforms can move along the first direction to drive the bar to approach or move away from the flaw detection device, and a bearing wheel mechanism for bearing 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, and the two movable clamping structures cooperate to clamp the two ends of the rod;

[0043] A rotary drive mechanism, which is mounted on one of the movable guide rail platforms and is used to drive the rod between the two movable clamping structures to rotate around its own axis;

[0044] The rod transfer device includes at least two rod transfer mechanisms 4, which are arranged along the second direction and located between two movable guide rail platforms; the rod transfer mechanism 4 is used to receive the rods after flaw detection and transfer the rods after flaw detection to the rod receiving device.

[0045] In this embodiment, when flaw detection is performed on the rod, the guide rail platform is first moved toward the direction close to the rod supporting platform to the clamping station. At this time, the rod to be inspected located on the clamping station is located between the two movable clamping structures, and the rod to be inspected located on the clamping station falls on the supporting wheel mechanism. Subsequently, the two movable clamping structures cooperate to clamp the two ends of the rod to be inspected, and the rotating drive mechanism drives the rod to be inspected located between the two movable clamping structures to rotate around its own axis. Subsequently, the mobile guide rail platform drives the rod to be inspected to move toward the flaw detection device until it moves to the flaw detection station. At this time, the rod to be inspected is still rotating around its axis. The flaw detection mechanism in the flaw detection device reciprocates along the second direction to inspect different positions of the rod to be inspected. After the flaw detection is completed, the mobile guide rail platform moves toward the rod bearing platform to the unloading station, so that the rod moves to the top of the rod transfer device. Subsequently, the rotary drive mechanism stops working and the two mobile clamping structures release the rod, and the rod falls onto the rod transfer device. The rod transfer device transfers the rod to the rod receiving device. Then, the mobile guide rail platform continues to move toward the rod bearing platform until it moves to the clamping station again, waiting for the next flaw detection work.

[0046] Compared with the existing self-spinning bar flaw detector, this bar flaw detector system has at least the following advantages:

[0047] First, the loading and unloading process is simpler and faster, which improves the efficiency of material change.

[0048] Second, the bar picking device with feeding function can drive the bar to rotate, thereby replacing the traditional bar rotating roller system. The system has higher system integration and there is no need to set up a bar rotating roller system, thus saving costs.

[0049] Thirdly, the bar receiving device not only has the function of receiving the bars, but also can provide buffer for the unloaded bars, thus avoiding the generation of loud abnormal noises when unloading the bars, and playing a role in protecting the bars.

[0050] In this embodiment, the first direction is the direction from the rod supporting platform 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, Figure 1 As shown, the movable guide rail platform, the bar material bearing platform and the flaw detection device are all arranged on the upper surface of the base 1. There are three movable guide rail platforms, which are arranged in sequence from left to right. The flaw detection device is located in front of the three movable guide rail platforms. There are two bar material transfer devices, which are respectively arranged in the space between two adjacent movable guide rail platforms.

[0052] Furthermore, the mobile guide rail platform includes a bearing seat, an industrial guide rail, a sliding table and a pushing cylinder 14, wherein the bearing seat is arranged on the base 1, two industrial guide rails are provided, the two industrial guide rails are arranged on the bearing seat, and the two industrial guide rails are perpendicular to the flaw detection device, at least one sliding block is slidably installed on the two industrial guide rails, the sliding table is fixedly installed on the sliding block of the industrial guide rail, and a pushing cylinder 14 is provided on the back side of the bearing seat, the outer shell of the pushing cylinder 14 is fixedly installed on the bearing seat, and its rod end is fixedly connected to the sliding table.

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

[0054] It should be noted that two limit switches are installed on the industrial guide rail, namely the first limit switch and the second limit switch. When the push cylinder 14 pulls the sliding table along the industrial guide rail to move away from the flaw detection device to the clamping station, the first limit switch gives a signal to the control box 2, indicating that the sliding table has reached the first limit position, and the control box 2 controls the push cylinder 14 to suspend work in preparation for clamping the rods on the rod support table. When the push cylinder 14 pushes the sliding table along the industrial guide rail to move toward the flaw detection device to the flaw detection station, the second limit switch gives a signal to the control box 2, indicating that the sliding table has reached the second limit position, and the control box 2 controls the push cylinder 14 to suspend work in preparation for flaw detection.

[0055] Preferably, considering that if only two mobile clamping structures are used to clamp the rod in mid-air, the load on the mobile clamping structures will be too large, at least one set of load-bearing wheel mechanisms are installed on the table surfaces of the sliding tables of the three mobile guide rail platforms, such as Figure 8As shown, the bearing wheel mechanism includes two guide wheel parts, which are arranged along the moving direction of the sliding table. The guide wheel parts include a portal frame 17, a roller 15 and an axle 16. The two portal frames 17 are installed in an inverted manner on the table surface of the sliding table. The axle 16 is installed on the top of the portal frame 17, and the axial direction of the axle 16 is the same as the axial direction of the rod. At least one roller 15 is rotatably installed on the axle 16. The bearing wheel mechanism is used to bear the rod, and the weight of the rod is borne by the bearing wheel mechanism. Therefore, the two movable clamping structures only need to cooperate to clamp the rod, and do not need to bear the weight of the rod. When the rod rotates, the rod will drive the roller 15 to rotate together. There is rolling friction between the rod and the roller 15, and the friction force is small.

[0056] Exemplarily, two bearings are coaxially arranged on the axle 16, and a roller 15 is arranged on the outer ring sleeve of the bearing, that is, two rollers 15 are rotatably mounted 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 movable guide rail platform is named as the first movable guide rail platform, the middle movable guide rail platform is named as the second movable guide rail platform, and the rightmost movable guide rail platform is named as the third movable guide rail platform.

[0058] like Figure 1 As shown, one mobile clamping structure is installed on the sliding platform of the first mobile guide rail platform, and the other mobile clamping structure is installed on the sliding platform of the second mobile guide rail platform. For the convenience of distinction, the mobile clamping structure on the left is named the first mobile clamping structure, and the mobile clamping structure on the right is named the second mobile clamping structure.

[0059] Among them, Figure 3 As shown, the first movable clamping structure includes a first guide rail 903, a first slider 904, a first fixed seat 905, a first cylinder 906 and a first sleeve 907. The first guide rail 903 is fixedly mounted on the sliding platform of the first movable guide rail platform, and the first guide rail 903 is arranged in the left-right direction, the first slider 904 is slidably mounted on the first guide rail 903, the first fixed seat 905 is in an L-plate shape, and has a bottom plate and a vertical plate connected to each other, the bottom plate is fixedly mounted on the first slider 904, and the first sleeve 907 is rotatably mounted on the right side of the vertical plate. A first fixed plate is arranged on the left side of the first guide rail 903, the first fixed plate is fixed on the sliding platform of the first movable guide rail platform, the first cylinder 906 is fixedly mounted on the first fixed plate, and the cylinder end of the first cylinder 906 is fixedly connected to the left end face of the first fixed seat 905.

[0060] It should be noted that the first sleeve 907 is cylindrical, and its inner diameter is larger than the outer diameter of the rod, so that the end of the rod can extend into the first sleeve 907.

[0061] Furthermore, the rotary drive mechanism is installed on the sliding table of the first movable guide rail platform, and the rotary drive mechanism includes a second motor 902, a reducer 910, a driving pulley, a driven pulley 908 and a transmission belt 909, wherein the driven pulley 908 is sleeved on the first sleeve 907, the driving pulley is installed on the output end of the reducer 910, the driving pulley and the driven pulley 908 are connected by a transmission belt 909, and the output end of the second motor 902 is connected to the input end of the reducer 910. The second motor 902 provides power to drive the driving pulley to rotate, and the driving pulley drives the driven pulley 908 to rotate through the transmission belt 909, and finally drives the first sleeve 907 to rotate.

[0062] In this embodiment, if Figure 4 As shown, the second movable clamping structure includes a second guide rail 133, a second slider 134, a second cylinder 135, a second fixed seat 136, a second fixed plate 132, and a second sleeve 137. The second guide rail 133 is mounted on the sliding table of the third movable guide rail platform, the second slider 134 is slidably mounted on the second guide rail 133, the bottom plate of the second fixed seat 136 is fixedly mounted on the second slider 134, the second sleeve 137 is rotatably mounted on the vertical plate of the second fixed seat 136, the second fixed plate 132 is located on the right side of the second guide rail 133, and is fixed on the sliding table of the third movable guide rail platform, the second cylinder 135 is fixedly mounted on the second fixed plate 132, and the cylinder end of the second cylinder 135 is fixed on the right side surface of the second fixed seat 136.

[0063] When taking materials, the control box 2 controls the pushing cylinders 14 of the three movable guide platforms to shorten at the same time to pull the three sliding platforms to move toward the rod supporting platform at the same time until they move to the clamping station. At this time, the rod located at the clamping station is just between the first sleeve 907 and the second sleeve 137. Then the control box 2 controls the first cylinder 906 and the second cylinder 135 to work at the same time. The first cylinder 906 and the second cylinder 135 extend a fixed distance to make the first sleeve 907 and the second sleeve 137 close to each other, thereby pressing and clamping the two ends of the rod. The two ends of the rod are respectively close to the inner walls of the first sleeve 907 and the second sleeve 137. Then the control box 2 controls the second motor 902 to work. The second motor 902 drives the 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 drives the first sleeve 907 to rotate. In this way, the rod rotates with the rotation of the first sleeve 907. During flaw detection, the rod rotates continuously around its own axis to facilitate flaw detection by the flaw detection device. There is no need to set up a rod rotating roller system, which saves costs and makes loading and unloading more convenient.

[0064] As a preferred embodiment, Figure 1 and Figure 2As shown, two bar material transfer mechanisms 4 are provided, wherein one bar material transfer mechanism 4 is located between the first movable guide rail platform and the second movable guide rail platform, and the other bar material transfer mechanism 4 is located between the second movable guide rail platform and the third movable guide rail platform. The two bar material transfer mechanisms 4 are arranged along the length direction of the bar material. Specifically, the bar material transfer mechanisms 4 are 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 rods. The two ends of the top plate 404 are respectively hinged to the top ends of the two telescopic members. The bent plate 405 is mounted on the top of the top plate 404 to support the rods and prevent them from rolling down.

[0065] Among them, one telescopic member is an electric cylinder 402, and the other telescopic member 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] In this way, when the three movable guide rail platforms move toward the bar bearing platform to the unloading station, the bar just moves to the top of the bar transfer mechanism 4 after flaw detection, and then the rotary drive mechanism stops working and the two movable clamping structures release the bar, and the bar falls onto the bent plate 405. Then the electric cylinder 402 and the electric telescopic rod 403 extend at the same time to raise the height of the bar, so that the height of the bar exceeds the bar receiving device, and 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, so that the top plate 404 tilts toward the flaw detection device to a certain extent, so that it is difficult to restrict the bar on the bent plate 405, and the bar then slides out of the bent plate 405 and falls 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 restriction 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 direction of the flaw detection device and are located in front of the flaw detection device. Specifically, the bar receiving mechanism 5 includes a bottom plate 501, a vertical rod 502, a top rod 503, a lifting block 504, an elastic member and a contact plate 507; wherein the vertical rod 502 is vertically arranged on the bottom plate 501, one end of the top rod 503 is connected to the vertical rod 502, and the other end thereof points to the bar bearing platform, and the height of the top rod 503 gradually decreases from the bar bearing 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 an obtuse angle.

[0070] Furthermore, the lifting block 504 is slidably mounted on the vertical rod 502, and the elastic member is disposed between the bottom plate 501 and the lifting block 504 to provide a buffer for the lifting block 504. The contact plate 507 is vertically mounted on the upper surface of the lifting block 504, the top of the contact plate 507 is higher than the top rod 503, and an accommodating space for accommodating the rod is formed between the side of the vertical rod 502 away from the top rod 503 and the contact plate 507.

[0071] It should be noted that the distance between the end of the push rod 503 pointing to the bar bearing platform and the bar transfer mechanism 4 is very close to ensure that the bars on the bar transfer mechanism 4 can smoothly roll onto the push rod 503. In addition, the push rod 503 is higher than the mobile clamping mechanism to avoid blocking the movement of the bars.

[0072] After the bar on the bar transfer mechanism 4 rolls onto the push rod 503, the height of the push rod 503 from one end close to the bar transfer mechanism 4 to the other end thereof gradually decreases, so that the bar rolls along the push rod 503 and is then stopped by the upper part of the contact plate 507. The bar hits the contact plate 507, and the impact force of the bar is mostly offset by the contact plate 507. Then the bar falls into the receiving space and acts on the lifting block 504. As the weight of the lifting block 504 increases, the elastic member is compressed, and the elastic member offsets the last kinetic energy of the bar. This ensures that when the bar is unloaded, the impact force of the bar is small, and the bar will not produce a large abnormal sound or a violent impact, thereby protecting the bar.

[0073] That is, the bar receiving device has the function of receiving the bars, and can also provide buffer for the unloaded bars, avoiding large abnormal noise when unloading the bars, thereby protecting the bars.

[0074] Moreover, when the electric cylinder 402 and the electric telescopic rod 403 synchronously lift the rod until the rod passes through the top rod 503, the rod is slightly higher than the top rod 503. Then, when the electric cylinder 402 continues to lift the rod so that the rod slides onto the top rod 503, since the height difference between the rod and the top rod 503 is relatively small at this time, the power of the rod is limited, and the impact force generated is also very limited, thereby ensuring that it can be unloaded quietly, the noise generated during the unloading process is small, and the surface will not be damaged due to severe collision. That is, because the actual falling height of the rod is small, its kinetic energy when falling is small.

[0075] The rod rolls along the push rod 503 and is stopped by the upper part of the contact plate 507, so that the impact force of the rod is further offset. After the rod falls into the receiving space, the elastic potential energy of the elastic member itself offsets the final kinetic energy of the rod.

[0076] Exemplarily, the contact plate 507 is a metal elastic plate, such as a stainless steel plate, a copper plate, etc. After the bar is blocked by the contact plate 507, the contact plate 507 itself has elasticity, thus playing a buffering role to a certain extent, and using the elasticity of the contact plate 507 itself to offset the impact force of the bar, so that the bar quickly stabilizes, and can also play a role in reducing noise.

[0077] In addition, it should be noted that the rods that fall into the material receiving space will eventually fall onto the upper surface of the lifting block 504. Under the gravity of the rods, the lifting block 504 moves downward. Due to the presence of the elastic member, the elastic member is slowly compressed, and the elastic member provides a buffer to offset the impact force generated when the rods fall, so that the lifting block 504 can move slowly downward.

[0078] As a specific embodiment, Figure 5 and Figure 6 As shown, a long strip-shaped sliding hole 505 is provided on the side of the vertical rod 502 and extends 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, and the vertical rod 502 is a U-shaped rod. A vertical round rod is provided 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, and the spring 506 is sleeved on the outside of the round rod. Further, as shown in FIG. Figure 7 The upper surface of the lifting block 504 is provided with a rectangular insertion hole and a through hole for the round rod to pass through.

[0079] In order to facilitate the installation and subsequent disassembly of the bar receiving mechanism 5, preferably, the bottom end side of the round rod has an external thread, and a threaded hole is opened on the upper surface of the bottom plate 501. Bolt holes are opened on both sides of the lower surface of the vertical rod 502, and countersunk holes corresponding to the bolt holes on the lower surface of the vertical rod 502 are opened on the bottom plate 501. 501, and finally, use the countersunk bolts to fix the vertical rod 502 and the bottom plate 501.

[0080] As a preferred embodiment, in order to further improve the anti-impact capability of the contact plate 507. In this embodiment, two support members are installed on the lifting block 504, and the support members include a one-to-one corresponding support plate 509 and an extension rod 508. The extension rod 508 is arranged on the end surface 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 to the end of the extension rod 508 away from the lifting block 504, and the other end thereof abuts against the contact plate 507. The 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 rod, the contact plate 507 bends outward. 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 excessively outward to ensure that the bending degree of the contact plate 507 is within the specified range, thereby ensuring that the contact plate 507 can completely block the rod, avoiding the rod from crossing the contact plate 507 and falling into the unloading area, thereby improving the safety when receiving the materials.

[0083] It should be noted that a cylinder is connected to one end of the support plate 509 that contacts the outer side surface of the contact plate 507 , 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 impact resistance of the contact plate 507 , a plurality of contact plates 507 may be provided, and the plurality of contact plates 507 are sequentially arranged along the length direction of the top rod 503 on the lifting block 504 .

[0085] Considering that when the bars in the receiving space cannot be removed in time, resulting in a large number of bars piled up in the receiving space, the sum of the weight of the lifting block 504 and the bars in the receiving space exceeds the load borne by the spring 506. When the spring 506 is subjected to a load exceeding its designed bearing capacity, the spring 506 will be permanently deformed or broken. To avoid such problems, it is preferred that Figure 6 and Figure 7 As shown, an auxiliary block 510 is inserted between the two extension rods 508. The cross section of the auxiliary block 510 is I-shaped, and the two sides thereof are respectively provided with slots adapted to the extension rods 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 contacts the bottom plate 501 before the lifting block 504.

[0086] In this way, when the weight of the lifting block 504 plus the weight of the bar in the receiving space 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 this time, most of the force acts on the auxiliary block 510 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 its service life is increased. In addition, the double buffering of the spring 506 and the auxiliary block 510 can greatly improve the bearing capacity of the bar receiving mechanism 5, and can carry more bars.

[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 material receiving space is large and the number of rods that can be accommodated is large, the length of the auxiliary block 510 can be appropriately increased; otherwise, it can be appropriately reduced.

[0088] In this embodiment, the first movable guide rail platform includes a first bearing seat 8, a first industrial guide rail 801, a first sliding table 9 and a first pushing cylinder 14, and a first bearing wheel mechanism 901 for supporting the rod is provided on the table top of the first sliding table 9.

Figure 1 and Figure 2As shown, the linear module mechanism 3 includes a strip-shaped carrying box, a tooth plate 301, a gear, a walking plate and a walking motor 302, wherein the tooth plate 301 is installed in the carrying box, the walking plate is slidably installed on the top of the carrying box, the gear and the tooth plate 301 are meshed, the walking motor 302 is installed on the top of the walking plate, and the output end of the walking motor 302 is connected to the gear. A fixed frame 303 is installed on the walking plate, and the flaw detection mechanism is installed on the top of the fixed frame 303. The gear is driven to rotate by the walking motor 302, and because the gear and the tooth plate 301 are meshed, the walking plate moves along the length direction of the tooth plate 301, that is, moves left and right, and finally drives the flaw detection mechanism to move back and forth to detect the rotating rod.

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

After the bar at the clamping station is removed, the next bar is moved to the clamping station by manual or truss robot to wait, and so on until all the bars on the bar bearing platform are inspected.
