Description

Technical Field

[0001] This application relates to the field of metal welded mesh inspection technology, and in particular to a non-destructive testing device and method for metal welded mesh. Background Technology

[0002] Welded wire mesh is made by melting and welding multiple interlaced metal wires at their intersections. After surface passivation and plasticizing treatment, it maintains a flat and firm mesh surface while also having high weather resistance and corrosion resistance. Therefore, welded wire mesh has been widely used in various industries.

[0003] To ensure the welding quality of the metal mesh, the welded joints are usually inspected after the welding is completed.

[0004] Currently, most existing metal welded mesh inspections employ non-destructive testing methods. Workers use handheld inspection probes to inspect each weld point on the metal welded mesh to ensure the welding quality.

[0005] Regarding the aforementioned technologies, the inventors discovered that since metal welded mesh is made of multiple metal wires interlaced and welded together, there are many welding points in the metal welded mesh. This results in a significant time commitment for workers when performing non-destructive testing on the welding points of the metal welded mesh, leading to a low testing efficiency when performing non-destructive testing on the metal welded mesh. Summary of the Invention

[0006] To alleviate the problem of low testing efficiency when performing non-destructive testing on welded metal mesh, this application provides a non-destructive testing device and method for welded metal mesh.

[0007] In the first aspect, this application provides a non-destructive testing device for welded metal mesh, which adopts the following technical solution:

[0008] A non-destructive testing device for welded metal mesh includes a conveying mechanism and a testing mechanism. The conveying mechanism supports and moves the welded metal mesh. The testing mechanism includes a first support and multiple sets of testing components. The first support is connected to the conveying mechanism, and the multiple sets of testing components are all connected to the first support. The multiple sets of testing components are arranged one-to-one with multiple welding points in the same row of the welded metal mesh. The multiple sets of testing components are used to simultaneously test the multiple welding points in the same row of the welded metal mesh.

[0009] By adopting the above technical solution, multiple sets of detection components are set on the first support. When non-destructive testing of the metal welded mesh is required, the metal welded mesh is first placed on the conveying mechanism. The conveying mechanism drives the metal welded mesh to move, and then the multiple sets of detection components on the first support test the welding points on the metal welded mesh row by row, thereby realizing automated testing of the metal welded mesh and improving the efficiency of non-destructive testing of the metal welded mesh.

[0010] Preferably, the conveying mechanism includes a drive assembly, a support frame, and multiple support rollers. The multiple support rollers are rotatably connected to the support frame and are spaced apart along the moving direction of the metal mesh. The drive assembly is connected to the support frame, and the multiple support rollers are connected to the drive assembly. The drive assembly drives the multiple support rollers to rotate synchronously. The first bracket is fixedly connected to the support frame.

[0011] By adopting the above technical solution, multiple support rollers are rotatably connected on the support frame. When inspecting the metal welded mesh, the drive assembly drives the multiple support rollers to rotate, so that the metal welded mesh is conveyed forward. Then, multiple sets of inspection components inspect the metal welded mesh row by row, which improves the convenience of inspecting the welding points of the metal welded mesh.

[0012] Preferably, each detection assembly includes a first cylinder, a detection block, and two detection probes. The first cylinder is connected to the first bracket, the detection block is fixedly connected to the piston rod of the first cylinder, the detection block is a "U"-shaped block, and the two detection probes are respectively fixedly connected to the two inner sidewalls of the detection block.

[0013] By adopting the above technical solution, the detection block is set as a "U" shaped block. After one row of welding points on the metal welded mesh moves to the bottom of the detection block, the first cylinder drives the detection block to move down, so that the detection probe on the detection block can detect the welding points of the metal welded mesh. The detection of the entire metal welded mesh can be achieved by the intermittent movement of the metal welded mesh.

[0014] Preferably, each of the detection blocks is provided with a marking component, which includes a storage tank, a discharge pipe and a spray gun. The storage tank and the spray gun are both fixedly connected to the detection block. The storage tank contains paint, and the storage tank is connected to the spray gun through the discharge pipe. The spray gun is used to spray paint onto the metal welded mesh.

[0015] By adopting the above technical solution, a marking component is set on the detection block. When the detection probe on the detection block detects that the welding point of the metal mesh is unqualified, the unqualified part of the metal mesh is marked by a spray gun, which makes it easier for the staff to identify the unqualified welding point of the metal mesh.

[0016] Preferably, the support frame is provided with a re-inspection mechanism, which includes a second bracket, an identification probe, a re-inspection component, and a second power component. The second bracket is fixedly connected to the support frame, the identification probe is set on the second bracket to identify the marked areas of the metal welded mesh, the re-inspection component is connected to the second bracket, and the second power component is connected to the second bracket to adjust the position of the re-inspection component.

[0017] By adopting the above technical solution, an identification probe is set on the second support. The identification probe identifies the marked welding points on the metal welded wire mesh, and then the second power component is activated. The second power component drives the re-inspection component to move, so that the re-inspection component can perform a second inspection on the marked welding points, thereby improving the accuracy of metal welded wire mesh inspection.

[0018] Preferably, each of the detection blocks is provided with a guide assembly, which includes two guide plates fixedly connected to the detection block. Both guide plates are parallel to the moving direction of the metal mesh, and each of the two guide plates has an inclined surface on one side close to the other. The two inclined surfaces are used to limit the metal wires on the metal mesh to guide the movement of the metal mesh.

[0019] By adopting the above technical solution, two guide plates are fixedly connected to each detection block. When the first cylinder drives the detection block to move down to detect the welding points on the metal wire mesh, the two guide plates fixedly connected to the detection block move down at the same time, so that the inclined surfaces on the guide plates correct the position of the metal wires on the metal wire mesh, reducing the possibility of the metal wire mesh shifting during transportation.

[0020] Preferably, a sorting mechanism is provided on the discharge side of the conveying mechanism. The sorting mechanism includes a sorting component, a rotating component, and a placement component for placing defective metal mesh. The sorting component includes a base, a support rod, a sorting frame, a fourth motor, a conveyor belt, and two conveyor rollers. The support rod is rotatably connected to the base and is perpendicular to the ground. The support rod rotates about its own axis. The sorting frame is fixedly connected to the support rod. The fourth motor is fixedly connected to the sorting frame. Both conveyor rollers are rotatably connected to the sorting frame. The fourth motor is coaxially fixedly connected to one of the conveyor rollers. The conveyor belt is sleeved on the outside of the two conveyor rollers. The rotating component is connected to the base and is connected to the support rod to drive the support rod to rotate. The placement component is located on one side of the sorting frame.

[0021] By adopting the above technical solution, the support rod is rotatably connected to the base. After the qualified metal welded wire mesh enters the conveyor belt on the sorting rack, it continues to be transported to the next process. After the unqualified metal welded wire mesh enters the conveyor belt, the rotating component drives the support rod to rotate, so that the conveyor belt above the support rod faces the placement component, and then the unqualified metal welded wire mesh is transported to the placement component, realizing the sorting of metal welded wire mesh and making it easy to reject the unqualified metal welded wire mesh.

[0022] Preferably, the placement assembly includes a placement frame, a winch, and multiple placement frames. The placement frame is located on one side of the sorting frame, the winch is fixedly connected to the placement frame, and the multiple placement frames are slidably connected to the placement frame. The multiple placement frames are arranged side by side along the direction perpendicular to the ground and are fixedly connected together. The pull rope on the winch is fixedly connected to one of the placement frames.

[0023] By adopting the above technical solution, multiple placement frames are slidably connected on the placement rack. After the identification probe identifies the unqualified welding points of the metal welded mesh, the height of the placement frames is adjusted so that metal welded mesh with different numbers of unqualified welding points enters different placement frames, realizing the detailed sorting of metal welded mesh and facilitating the subsequent processing of metal welded mesh by the staff according to the product quality.

[0024] Preferably, the support frame is provided with a control component, which includes a blocking plate and a contact switch. The blocking plate is slidably connected to the support frame and is located at the discharge end of the support frame to block the metal mesh conveyed on the support frame. The contact switch is connected to the side of the blocking plate near the support frame. The conveying mechanism and the detection mechanism are both electrically connected to the contact switch. The blocking plate is connected to the rotating component. When the rotating component drives the support rod to rotate, the rotating component simultaneously drives the blocking plate to move to block the metal mesh on the support frame.

[0025] By adopting the above technical solution, the rotating component drives the blocking plate to move. When the metal mesh with unqualified weld points is transported to the conveyor belt, the rotating component drives the support rod to rotate. At the same time, the rotating component drives the blocking plate to move, so that the blocking plate blocks the metal mesh to be inspected by the support frame. This reduces the possibility of the metal mesh being transported to the conveyor belt and affecting the metal mesh sorting. When the metal mesh being transported to the conveyor belt comes into contact with the contact switch, the contact switch can control the conveying mechanism and the inspection mechanism to stop running, reducing the possibility of damage to the inspection device caused by continued operation.

[0026] Secondly, this application provides a non-destructive testing method for welded metal mesh, which adopts the following technical solution:

[0027] A non-destructive testing method for welded metal mesh includes the following steps:

[0028] S1: Material conveying, placing the welded metal mesh on the conveying mechanism for conveying the welded metal mesh;

[0029] S2: Preliminary inspection, during the transportation process, non-destructive testing is carried out on each row of the welded metal mesh by an inspection agency;

[0030] S3: Marking, using marking components to mark unqualified welding points on metal welded wire mesh;

[0031] S4: Re-inspection, identify the marked metal welded mesh, and then conduct a second inspection on unqualified weld points;

[0032] S5: Sorting, classifying and placing the metal mesh according to the number of defective weld points.

[0033] By adopting the above technical solution, the metal welded mesh is inspected row by row by the conveying mechanism, and then the unqualified welding points are inspected a second time by the re-inspection mechanism. This achieves automated inspection while ensuring the accuracy of the inspection results. Then, the metal welded mesh is classified and placed according to the number of unqualified welding points by the sorting mechanism, which facilitates the subsequent processing of the metal welded mesh.

[0034] In summary, this application includes at least the following beneficial technical effects:

[0035] 1. By setting multiple sets of detection components on the first support, when inspecting the metal welded mesh, the metal welded mesh is first placed on the conveying mechanism, and the conveying mechanism drives the metal welded mesh to move. During the movement of the metal welded mesh, the multiple sets of detection components on the first support are used to inspect the welding points on the metal welded mesh row by row, thereby realizing the automated inspection of the metal welded mesh and improving the efficiency of non-destructive testing of the metal welded mesh.

[0036] 2. By setting a marking component on each detection block, after the detection component detects a non-conforming welding point of the metal welded mesh, the marking component marks the non-conforming part of the metal welded mesh, which makes it easier for the staff to identify the non-conforming welding point of the metal welded mesh;

[0037] 3. By sliding multiple placement frames on the placement rack, after the identification probe identifies the unqualified welding points of the metal welded mesh, the height of the placement frames is adjusted so that metal welded mesh with different numbers of unqualified welding points enters different placement frames, thereby achieving detailed sorting of metal welded mesh and facilitating the classification and processing of metal welded mesh.

[0048] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0049] This application discloses a non-destructive testing device for welded metal mesh.

[0050] Reference Figure 1A non-destructive testing device for welded metal mesh includes a conveying mechanism 100, a testing mechanism 200, and a sorting mechanism 400. The conveying mechanism 100 conveys the welded metal mesh to be tested. The testing mechanism 200 is mounted on the conveying mechanism 100 and is used to automatically test the weld points on the conveyed welded metal mesh. The sorting mechanism 400 is located at the discharge end of the conveying mechanism 100 and is used to sort the tested welded metal mesh, separating qualified welded metal mesh from unqualified welded metal mesh. The automated testing of welded metal mesh is achieved through the cooperation of the conveying mechanism 100 and the testing mechanism 200, thereby improving the efficiency of non-destructive testing of welded metal mesh.

[0051] Reference Figure 1 and Figure 2 The conveying mechanism 100 includes a support assembly 110, which includes a support frame 111. Multiple support rollers 112 are rotatably connected to the support frame 111, with their rotation axes arranged parallel to each other and spaced apart along the length of the support frame 111. A drive assembly 120 is mounted on the support frame 111, which drives the multiple support rollers 112 to rotate synchronously. During non-destructive testing of the welded metal mesh, after placing the welded metal mesh on the multiple support rollers 112, the drive assembly 120 drives the multiple support rollers 112 to rotate, thus achieving the conveying of the welded metal mesh.

[0052] The drive assembly 120 includes a first motor 121, which is fixedly connected to the side wall of the support frame 111. A rotating rod 122 is rotatably connected to one side of the support frame 111. The rotation axis of the rotating rod 122 is parallel to the length direction of the support frame 111. The first motor 121 and the rotating rod 122 are coaxially fixedly connected. Multiple first bevel gears 123 are coaxially fixedly connected to the rotating rod 122, and the multiple first bevel gears 123 are spaced apart along the length of the rotating rod 122. Each support roller 112 has a second bevel gear 124 coaxially fixedly connected to one end. The multiple first bevel gears 123 and multiple second bevel gears 124 are arranged in a one-to-one correspondence, and the first bevel gear 123 meshes with its corresponding second bevel gear 124. The rotation of the main shaft of the first motor 121 drives the rotating rod 122 to rotate, which in turn drives the multiple first bevel gears 123 coaxially fixedly connected to it to rotate, thereby driving the multiple second bevel gears 124 to rotate, thus realizing the synchronous rotation of the multiple support rollers 112.

[0053] Reference Figure 1 , Figure 2 and Figure 3The testing mechanism 200 includes a first bracket 210, which is fixedly connected above the support frame 111. A first groove 211 is provided on the first bracket 210, which is opened along the width direction of the support frame 111.

[0054] Reference Figure 3 , Figure 4 and Figure 5 Multiple sets of detection components 220 are installed on the first bracket 210. These components are spaced apart along the width of the support frame 111. Each detection component 220 includes a first slider 221, which is adapted to a first slide groove 211 and slidably connected within the groove. A first cylinder 222 is fixedly connected below the first slider 221, and is vertically positioned. A detection block 223, a U-shaped block with its opening facing the ground, is fixedly connected to the piston rod of the cylinder. Detection probes 224 are fixedly connected to the two inner sidewalls of the detection block 223, and are positioned opposite each other. A first power assembly 230 is installed on the first bracket 210 to drive the multiple first sliders 221 to move. When the welded metal mesh moves below the first support 210, multiple first cylinders 222 drive multiple detection blocks 223 to move downwards, causing the detection blocks 223 to respectively engage with multiple welding points on both sides of the same row of the welded metal mesh. This allows for simultaneous detection of multiple welding points in the same row. Then, as the welded metal mesh moves, it is inspected row by row, completing the non-destructive testing of the welded metal mesh. By slidably connecting multiple first sliders 221 within the first slide groove 211 and using the first power assembly 230 to drive the movement of the first sliders 221, the movement of the first sliders 221 drives the connected detection blocks 223 to move, enabling the detection blocks 223 to inspect welded metal meshes of different mesh sizes, thus improving the applicability of the testing device.

[0055] Reference Figure 3 and Figure 4 The first power assembly 230 includes a first rack 231 fixedly connected above the first bracket 210, the length direction of the first rack 231 being parallel to the width direction of the support frame 111. A second motor 232 is fixedly connected above each first slider 221, the main shaft of the second motor 232 being perpendicular to the ground. A first gear 233 is coaxially fixedly connected to the main shaft of each second motor 232, and each first gear 233 meshes with the first rack 231. When the position of the detection block 223 needs to be adjusted, the rotation of the main shaft of the second motor 232 drives the first gear 233 coaxially fixedly connected to it to rotate. The engagement of the first gear 233 with the first rack 231 enables the movement of the first slider 221, thereby adjusting the position of the detection block 223.

[0056] Reference Figure 3 , Figure 4 and Figure 5 To reduce the possibility of skewing during the movement of the welded wire mesh, each detection block 223 is equipped with a set of guide components 250. Each guide component 250 includes a connecting rod 251, which is fixedly connected to the detection block 223 and is horizontally positioned. Two guide plates 252 are fixedly connected to the connecting rod 251. Both guide plates 252 are parallel to the conveying direction of the welded wire mesh and are positioned opposite each other, with a gap between them to accommodate the metal wires on the welded wire mesh. An inclined surface is formed on the side of each guide plate that is close to each other, with the ends of the two inclined surfaces near the ground tilting away from each other. When the first cylinder 222 moves downward, causing the detection block 223 to detect the welded wire mesh, it simultaneously moves the two guide plates 252 downward, using the inclined surfaces on the two guide plates 252 to guide the metal wires on the welded wire mesh. If the position of the welded wire mesh shifts, it will return to its original position under the push of the inclined surfaces of the two guide plates 252. During the inspection of the metal welded mesh, the position of the metal welded mesh is guided and corrected once for each row of welded points inspected, reducing the possibility of the metal welded mesh shifting during transportation; and the guide component 250 can change the inspection position as the inspection block 223 moves, ensuring the applicability of the guide component 250.

[0057] Reference Figure 4 and Figure 5 Each detection block 223 is equipped with a marking component 240. Each group of marking components 240 includes a storage tank 241, which is fixedly connected to the corresponding detection block 223. The storage tank 241 is used to hold the coating. A discharge pipe 242 is fixedly connected to the storage tank 241. One end of the discharge pipe 242 is connected to the inside of the storage tank 241, and the other end is connected to a spray gun 243, which is fixedly connected to the detection block 223. When the detection probe 224 on the detection block 223 detects a defective weld point in the metal mesh, the corresponding spray gun 243 is activated to spray the coating onto the defective weld point, marking the defective weld point for easy identification by staff.

[0058] Reference Figure 1 and Figure 6To improve the accuracy of metal welded mesh inspection, a re-inspection mechanism 300 is provided on the support frame 111. The re-inspection mechanism 300 is located on the side of the first support 210 away from the metal welded mesh feed. The re-inspection mechanism 300 includes a second support 310, on which multiple identification probes 320 are fixedly connected. The identification probes 320 are used to identify the coating sprayed on the metal welded mesh.

[0059] Reference Figure 1 and Figure 6 The second support 310 is equipped with a second power assembly 330 and a re-inspection assembly 340. The second power assembly 330 is used to drive the re-inspection assembly 340 to re-inspect the non-conforming points of the welded metal mesh. The second power assembly 330 includes a third motor 331 fixedly connected to the second support 310, and multiple identification probes 320 are electrically connected to the third motor 331. Two sprockets 332 are rotatably connected to the second support 310. The rotation axes of the two sprockets 332 are parallel and located in the same plane. The two sprockets 332 are located near both ends of the second support 310. The main shaft of the third motor 331 is coaxially fixedly connected to one of the sprockets 332, and chains 333 are sleeved on the outer sides of the two sprockets 332.

[0060] The re-inspection assembly 340 includes a second slider 341, which is fixedly connected to a chain 333. A second slide groove 311 is provided on the second bracket 310 along the length of the second bracket 310. The second slider 341 is adapted to the second slide groove 311 and is slidably connected within the second slide groove 311. A second cylinder 342 is fixedly connected below the second slider 341 and is vertically arranged. A re-inspection block 343 is fixedly connected to the piston rod of the second cylinder 342. The re-inspection block 343 is a "U"-shaped block with its opening facing the ground. Re-inspection probes 344 are fixedly connected to the two inner sidewalls of the re-inspection block 343. The detection direction of the re-inspection probes 344 is perpendicular to the detection direction of the detection probe 224. The re-inspection probes 344 are used to re-inspect the welding points of the metal welded mesh that are not up to standard. After the testing agency 200 detects unqualified welding points, the spray gun 243 sprays dye to mark the unqualified welding points. Once the paint on the unqualified welding points on the metal welded mesh is detected by the identification probe 320, the third motor 331 is started. The rotation of the main shaft of the third motor 331 drives the sprocket 332 fixedly connected to it to rotate, thereby causing the chain 333 to drive the second slider 341 to adjust the position of the re-inspection block 343. Then, the second cylinder 342 drives the re-inspection block 343 to move down, so that the re-inspection probe 344 can re-inspect the unqualified welding points of the metal welded mesh, thereby improving the accuracy of the metal welded mesh inspection results. By setting the detection direction of the re-inspection probe 344 perpendicular to the detection direction of the detection probe 224, the re-inspection of the metal welded mesh can be carried out in a different direction than the first inspection, further improving the accuracy of the re-inspection data.

[0061] Reference Figure 1 and Figure 7 The sorting mechanism 400 includes a sorting assembly 410, which includes a base 411. A support rod 412 is rotatably connected to the base 411. The support rod 412 is vertically arranged and rotates along its own axis. A sorting frame 413 is fixedly connected to the upper end of the support rod 412. Two conveyor rollers 414 are rotatably connected to the sorting frame 413. Both conveyor rollers 414 are parallel to the width direction of the sorting frame 413 and are located near both ends of the sorting frame 413. A fourth motor 415 is fixedly connected to the sorting frame 413. The main shaft of the fourth motor 415 is coaxially fixedly connected to one of the conveyor rollers 414. A conveyor belt 416 is sleeved on the outer side of the two conveyor rollers 414, and the two conveyor rollers 414 are connected by transmission through the conveyor belt 416. A rotating assembly 420 is installed on the base 411 to drive the support rod 412 to rotate. A placement component 430 is installed on one side of the sorting rack 413. The placement component 430 is used to place metal mesh with defective weld points.

[0062] Figure 1 , Figure 7 and Figure 8 The rotating assembly 420 includes a fifth motor 421 and two second gears 422. The fifth motor 421 is fixedly connected to the base 411. The main shaft of the fifth motor 421 is coaxially fixedly connected to one of the second gears 422. The other second gear 422 is coaxially sleeved on the outside of the support rod 412. The support rod 412 is coaxially fixedly connected to the second gear 422 sleeved on its outside. The two second gears 422 are meshed together. After being inspected by the inspection agency 200 and the re-inspection agency 300, qualified metal welded wire mesh enters the conveyor belt 416 on the sorting rack 413 and continues to be conveyed to the next process. Unqualified metal welded wire mesh enters the conveyor belt 416 and is then started by the fifth motor 421. The fifth motor 421 and the two second gears 422 work together to drive the support rod 412 to rotate. The rotation of the support rod 412 drives the sorting rack 413 and the conveyor belt 416 fixedly connected above it to rotate, thereby conveying the unqualified metal welded wire mesh to the placement component 430, thus realizing the sorting of the metal welded wire mesh and making it easier to reject the unqualified metal welded wire mesh.

[0063] Reference Figure 7 and Figure 9 The placement assembly 430 includes a placement frame 431, within which multiple placement frames 432 are slidably connected. These placement frames 432 are arranged side-by-side vertically and are fixedly connected together. Four guide rails 433 are fixedly connected within the placement frame 431, located near the four corners of the frame. Each placement frame 432 has four guide blocks 434 fixedly connected, each corresponding to one of the four guide rails 433, and the guide blocks 434 are slidably connected to their respective rails. A winch 435 is fixedly connected above the placement frame 431, and the steel cable on the winch 435 is fixedly connected to the uppermost placement frame 432. By sliding multiple placement frames 432 on the placement rack 431, and using the identification probe 320 to identify the unqualified welding points of the metal wire mesh, the height of the placement frame 432 is adjusted according to the number of unqualified welding points on the metal wire mesh, so that metal wire mesh with different numbers of unqualified welding points enters different placement frames 432 respectively, thereby achieving more detailed sorting of metal wire mesh and facilitating the classification and processing of metal wire mesh.

[0064] Reference Figure 9Each placement frame 432 is equipped with a dragging assembly 440. The dragging assembly 440 includes a sixth motor 441 fixedly connected to the top of the placement frame 432. The main shaft of the sixth motor 441 is coaxially fixedly connected to a lead screw 442. The lead screw 442 is rotatably connected to the top of the placement frame 432. The rotation axis of the lead screw 442 is parallel to the length direction of the placement frame 432. A sliding block 443 is threadedly connected to the lead screw 442. The sliding block 443 is slidably connected to the placement frame 432. An electromagnet 444 is fixedly connected to the lower end of the sliding block 443. When the conveyor belt 416 transports the metal welded wire mesh into the placement frame 432, after the conveyor belt 416 transports one end of the metal welded wire mesh into the placement frame 432, the electromagnet 444 attracts one end of the metal welded wire mesh, and then drives the sixth motor 441. The sixth motor 441 drives the lead screw 442 to rotate, which in turn drives the sliding block 443 to move, so that the electromagnet 444 drags the metal welded wire mesh into the placement frame 432, improving the convenience of the metal welded wire mesh entering the placement frame 432.

[0065] Reference Figure 1 , Figure 7 and Figure 8 To facilitate the control of the transfer of the welded metal mesh, a control component 450 is installed on the support frame 111. The control component 450 includes a support plate 451, which is horizontally arranged and fixedly connected to the discharge end of the support frame 111. A lifting rod 452 is inserted through the support plate 451 and is vertically arranged. A blocking plate 453 is fixedly connected to the upper end of the lifting rod 452. The blocking plate 453 is perpendicular to the moving direction of the welded metal mesh and is used to block the welded metal mesh. A contact switch 454 is installed on the side of the blocking plate 453 near the support frame 111. The first motor 121, the second motor 232, and the third motor 331 are all electrically connected to the contact switch 454.

[0066] A lifting rod 455 is fixedly connected to the side wall of the lifting rod 452. The length direction of the lifting rod 455 is parallel to the rotation axis of the support roller 112. A second rack 456 is slidably connected to the support plate 451. The length direction of the second rack 456 is parallel to the conveying direction of the metal welded mesh. The second rack 456 meshes with a second gear 422 that is coaxially fixedly connected to the support rod 412. A push block 457 is fixedly connected to one end of the second rack 456 near the support frame 111. The upper surface of the push block 457 is inclined. The height of the upper surface of the push block 457 near the support frame 111 is lower than the height of the end away from the support frame 111. The lifting rod 455 abuts against the upper surface of the push block 457. After the metal mesh with defective welded points is conveyed onto the conveyor belt 416, the fifth motor 421 drives the two second gears 422 to rotate, which in turn drives the support rod 412 to rotate. The second gear 422, which is fixedly connected to the support rod 412, simultaneously drives the second rack 456 meshing with it to slide. The sliding of the second rack 456 drives the push block 457 to slide, so that the push block 457 uses the inclined surface to drive the lifting rod to move upward, thereby realizing the upward movement of the lifting rod 452 and the blocking plate 453. The blocking plate 453 blocks the subsequent conveyed metal mesh on the conveying mechanism 100, reducing the possibility that the subsequent conveyed metal mesh will continue to be conveyed and affect the sorting component 410 sorting. When the metal mesh comes into contact with the contact switch 454 on the blocking plate 453, the contact switch 454 controls the first motor 121, the second motor 232 and the third motor 331 to turn off. After the sorting component 410 sorts the unqualified metal wire mesh, the fifth motor 421 drives the support rod 412 to reset through the two second gears 422, and at the same time drives the second rack 456 and the push block 457 to move back, so that the blocking plate 453 and the lifting rod 452 fall under the action of gravity. At this time, the contact switch 454 separates from the metal wire mesh, so that the first motor 121, the second motor 232 and the third motor 331 can be restarted to continue to transport and inspect the metal wire mesh.

[0067] This application also discloses a non-destructive testing method for welded metal mesh, which uses the aforementioned non-destructive testing device for welded metal mesh and includes the following steps:

[0068] S1: Material conveying, placing the metal welded mesh on the conveying mechanism 100 to convey the metal welded mesh;

[0071] S4: Re-inspection, identify the marked metal welded mesh, and then conduct a second inspection on unqualified weld points;

[0072] S5: Sorting, classifying and placing the metal mesh according to the number of defective weld points.

[0073] The implementation principle of the non-destructive testing device and method for welded metal mesh in this application embodiment is as follows: By installing a testing mechanism 200 and a re-inspection mechanism 300 on the conveying mechanism 100, when testing the welded metal mesh, the welded metal mesh is first placed on the conveying mechanism 100, and the conveying mechanism 100 drives the welded metal mesh to move. During the movement, the testing mechanism 200 tests the welding points on the welded metal mesh row by row, and the re-inspection mechanism 300 performs a second test on the unqualified welded metal mesh, thereby improving the accuracy of the test results and realizing automated testing of the welded metal mesh, thus improving the efficiency of non-destructive testing of the welded metal mesh.
