Description

Technical Field

[0001] The present application relates to the technical field of vehicle welding quality detection, and in particular to a method and system for detecting welding defects of a truck beam. Background Art

[0002] In the production process of truck beams, welding is a key link, and the welding quality directly affects the strength of the beam and the safety of the vehicle. Due to the long length and heavy weight of the beam, it is difficult to flip and occupies a large area.

[0003] The truck beam is made of multiple steel plates welded into an H-shaped steel structure. The welding process is complicated, and manual inspection cannot efficiently and comprehensively identify all welding defects. Existing welding defect detection equipment, such as traditional inspection robots or automated inspection systems, are usually large in size, occupy a large area, and require complex spatial layout. For small workshops with limited space, it is difficult to detect the welds on the inside of the beam. Summary of the invention

[0004] In order to facilitate detection and reduce floor space, the present application provides a truck beam welding defect detection method and system.

[0005] On the one hand, the present application provides a truck beam welding defect detection system, which adopts the following technical solution: A truck beam welding defect detection system, comprising: frame; A receiving portion, arranged on the frame and used for receiving the beam; A first semi-ring track is slidably disposed on the frame along a vertical direction and is located above the receiving portion, with an opening of the first semi-ring track facing downward; A second semi-ring track, wherein the second semi-ring track is located below the first semi-ring track, and an opening of the second semi-ring track faces upward; A driving assembly, the driving assembly is used to drive the first half-ring track and the second half-ring track to move along the length direction of the receiving portion; A lifting assembly, arranged on the frame and used for driving the first half-ring track to lift and lower; A detection module is used to detect beam welding defects. The detection module is arranged on the first semi-ring track and the second semi-ring track and can move along the first semi-ring track and the second semi-ring track.

[0006] By adopting the above technical solution, the welded truck beam is moved from one side of the receiving part to the receiving part, and the first semi-ring track is driven by the lifting component to move downward to be close to the second semi-ring track; when the detection module detects the welding seam of the beam, the detection module moves along the first semi-ring track and the second semi-ring track, so that the circumferential direction of the beam can be detected by the detection module; at the same time, the first semi-ring track and the second semi-ring track are driven by the driving component to move along the length direction of the receiving part to complete the detection of the entire beam.

[0007] After the inspection is completed, the first half-ring track is driven upward by the lifting assembly, and then the beam is removed from the other side of the receiving part. The space occupied by the entire equipment is equivalent to the length of the beam, which effectively reduces the space occupied by the workshop; and there is no need to flip the beam during the entire inspection process, which makes the inspection convenient.

[0008] Optionally, the receiving portion includes a side plate and a plurality of receiving rollers, wherein two side plates are horizontally arranged, the receiving roller is rotatably arranged between the two side plates, and the plurality of receiving rollers are arranged on the side plate at intervals.

[0009] Optionally, the frame is provided with an abutting portion for abutting against one end of the beam, and the frame is provided with a pushing member for abutting against the other end of the beam and capable of pushing the beam to move.

[0010] By adopting the above technical solution, after the beam is placed on the receiving roller, the pusher pushes the beam to move so that the other end of the beam is pressed against the abutment portion, so that the position of the beam is limited, preventing the beam from shifting during the detection process, and ensuring the accuracy of the detection. After the first round of detection is completed, the pusher continues to push the beam a short distance so that the position where the beam contacts the receiving roller moves to between the two receiving rollers, revealing the blocked part. At this time, the beam is detected again so that all parts of the entire beam can be detected, thereby improving the accuracy of the detection results.

[0011] Optionally, the abutment portion includes an abutment plate and an elastic member, the abutment plate is slidably disposed on the side plate along the length direction of the side plate, and the elastic member is used to drive the abutment plate to slide in a direction close to the receiving roller.

[0012] Optionally, the detection module includes a moving seat and a camera module. The detection modules are arranged on the first semi-ring track and the second semi-ring track. The moving seat can move along the first semi-ring track or the second semi-ring track. The camera module is arranged on the moving seat for photographing the beam weld.

[0013] Optionally, a moving block is disposed on the moving seat, a driving member for driving the moving block to move is disposed on the moving seat, and the camera module is disposed on the moving block.

[0014] By adopting the above technical solution, during the detection process, for some unclear positions, the driving member can drive the moving block to move closer to the beam, thereby shortening the distance between the camera module and the beam and improving the detection accuracy. In addition, because some truck beams have curved sections, when the detection module moves to this position, the detection module on one side is far away from the beam during the circular motion, and when it rotates to the other side, it is closer to the beam and even interferes with the beam; at this time, the driving member can be used to drive the moving block to ensure that the distance between the camera module and the beam remains constant, improve the detection quality, and prevent the curved part from interfering with the movement of the camera module.

[0015] Optionally, a blowing assembly is provided on the movable seat, and the blowing assembly includes an air nozzle, an air pipe and an air pump. The air nozzle is provided on the movable block, and the air pump is provided on the movable seat. One end of the air pipe is connected to the output end of the air pump, and the other end is connected to the air nozzle.

[0016] By adopting the above technical solution, there may be welding smoke or dust in the workshop. During the detection process, if the air pump pumps air to the air nozzle through the air pipe, the air nozzle blows air toward the beam, thereby blowing away the smoke or dust in the air between the camera module and the beam, and at the same time cleaning the dust on the beam, so that the camera module can capture the weld of the beam more clearly, thereby improving the detection effect.

[0017] Optionally, two positioning blocks are slidably provided on the first semi-ring track and the second semi-ring track, the two positioning blocks are respectively located on both sides of the detection module, and the positioning blocks are provided with travel switches.

[0018] By adopting the above technical solution, the angle formed by the two welds inside the beam and the extended lines of the edges of the two wing plates is the maximum detection angle range of the detection module. During the detection process, when the moving seat contacts the two travel switches, the moving direction of the moving seat will be changed, that is, the moving range of the moving seat is between the two travel switches, and there is no need to move to the entire first semi-ring track or the second semi-ring track, thereby reducing the moving distance of the moving seat and improving the detection efficiency.

[0019] Optionally, a limiting member for limiting the position of the positioning block is provided on the positioning block, and a laser positioning member is provided on the positioning block, wherein the laser direction of the laser positioning member faces the beam.

[0020] By adopting the above technical solution and adjusting the position between the two positioning blocks, it is possible to adapt to beams of different sizes and improve applicability.

[0021] On the other hand, the present application provides a method for detecting welding defects of a truck beam, which adopts the following technical solution: A method for detecting welding defects of a truck beam comprises the following steps: Move the welded truck beam from one side of the receiving part to the receiving part, and keep the waist plate of the beam in a horizontal state; The first half-ring track is driven downward to be close to the second half-ring track by the lifting assembly; The first half-ring track and the second half-ring track are driven by the driving assembly to reciprocate along the length direction of the receiving portion, and the detection module is moved along the first half-ring track and the second half-ring track at the same time, and the welding seam of the beam is detected by the detection module to obtain detection data; Use defect assessment software or manual judgment to determine whether there are defects in the weld, as well as the type, size, and location of the defects; After the inspection is completed, the first half ring track is driven upward by the lifting assembly, and then the beam is removed from the other side of the receiving part.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the detection module detects the welding seam of the beam, the detection module moves along the first half-ring track and the second half-ring track, so that the circumferential direction of the beam can be detected by the detection module; at the same time, the first half-ring track and the second half-ring track are driven by the driving component to move along the length direction of the receiving part to complete the detection of the entire beam. After the detection is completed, the first half-ring track is driven upward by the lifting component, and then the beam is removed from the other side of the receiving part. The space occupied by the entire equipment is equivalent to the length of the beam, which effectively reduces the space occupied by the workshop; and there is no need to flip the beam during the entire detection process, which is convenient for detection.

[0023] 2. After the beam is placed on the receiving roller, the pusher is used to push the beam to move so that the other end of the beam is pressed against the abutment part, so that the position of the beam is limited, preventing the beam from shifting during the detection process and ensuring the accuracy of the detection. After the first round of detection is completed, the pusher is used to continue to push the beam a short distance so that the position where the beam contacts the receiving roller moves to between the two receiving rollers, revealing the blocked part. At this time, the beam is tested again so that all parts of the entire beam can be tested, thereby improving the accuracy of the test results.

[0024] 3. During the detection process, for some unclear positions, the driving member can drive the moving block to move closer to the beam, thereby shortening the distance between the camera module and the beam and improving the detection accuracy. In addition, because some truck beams have curved sections, when the detection module moves to this position, the detection module on one side is far away from the beam during the circular motion, and when it rotates to the other side, it is closer to the beam and even interferes with the beam; at this time, the driving member can drive the moving block to move to ensure that the distance between the camera module and the beam remains constant, improve the detection quality, and prevent the curved part from interfering with the movement of the camera module.

[0025] 4. There may be welding smoke or dust in the workshop. During the inspection process, if the air pump pumps air to the air nozzle through the air pipe, the air nozzle blows air to the beam, thereby blowing away the smoke or dust in the air between the camera module and the beam, and at the same time cleaning the dust on the beam, so that the camera module can capture the weld of the beam more clearly, thereby improving the inspection effect.

[0032] An embodiment of the present application discloses a truck beam welding defect detection system.

[0033] Reference Figure 1 A truck beam welding defect detection system includes a frame 1, a receiving part 2, a driving assembly 3, a first half-ring track 41, a second half-ring track 42 and a detection module 7, wherein the detection module 7 is used to detect welding defects of the beam 10.

[0034] Reference Figure 1 and Figure 2The receiving part 2 is arranged on the frame 1 for receiving the beam 10. The receiving part 2 includes a side plate 21 and a plurality of receiving rollers 22. Two side plates 21 are arranged horizontally. The side plates 21 are fixedly connected at the head and tail to form a rectangular frame structure. The length direction of the receiving part 2 is the length direction of the side plate 21. The side plate 21 is fixedly arranged on the frame 1. The receiving roller 22 is rotatably arranged between the two side plates 21. The plurality of receiving rollers 22 are arranged at intervals on the side plates 21. The spacing between the two receiving rollers 22 at the head and tail ends is less than the length of the beam 10. During the inspection, the I-shaped truck beam 10 is placed flat on the receiving roller 22.

[0035] Optional, see Figure 1 and Figure 2 The frame 1 is provided with an abutting portion for abutting against one end of the beam 10, and the abutting portion includes an abutting plate 51 and an elastic member 52. The abutting plate 51 is slidably provided on the side plate 21 along the length direction of the side plate 21, and the elastic member 52 is used to drive the abutting plate 51 to slide in the direction close to the receiving roller 22. Specifically, a connecting plate 23 is fixedly provided at the end of the side plate 21, and a sliding rod 53 is slidably penetrated on the connecting plate 23 along the length direction parallel to the side plate 21. Two sliding rods 53 are provided, and the abutting plate 51 is fixedly provided at one end of the sliding rod 53 away from the connecting plate 23. The elastic member 52 is a compression spring sleeved on the sliding rod 53, one end of the compression spring abuts against the connecting plate 23, and the other end abuts against the abutting plate 51.

[0036] Reference Figure 1 and Figure 2 The frame 1 is provided with a pusher for contacting with the other end of the beam 10 and pushing the beam 10 to move. In this embodiment, the pusher includes a push cylinder 61 and a push plate 62. The push cylinder 61 is horizontally fixed on the connecting plate 23 at one end of the side plate 21, and the push plate 62 is fixed on the piston rod of the push cylinder 61. When the push cylinder 61 is extended and retracted, it can push the push plate 62 to move along the length direction of the side plate 21, so that the push plate 62 contacts with the end of the beam 10 and pushes the beam 10 to move.

[0037] After the beam 10 is placed on the receiving roller 22, the pusher pushes the beam 10 to move so that the other end of the beam 10 is pressed against the abutment portion, so that the position of the beam 10 is limited, preventing the beam 10 from shifting during the detection process, and ensuring the accuracy of the detection. After the first round of detection is completed, the pusher continues to push the beam 10 to move a short distance so that the position where the beam 10 contacts the receiving roller 22 moves to between the two receiving rollers 22, revealing the blocked part. At this time, the beam 10 is detected again so that all parts of the entire beam 10 can be detected, thereby improving the accuracy of the detection results.

[0038] Reference Figure 1 and Figure 3The first semi-ring track 41 is slidably disposed on the frame 1 along the vertical direction and is located above the receiving portion 2. The opening of the first semi-ring track 41 faces downward and the first semi-ring track 41 is in a circular shape. The second semi-ring track 42 is located below the first semi-ring track 41 and the opening of the second semi-ring track 42 faces upward. The first semi-ring track 41 and the second semi-ring track 42 are directly opposite to each other, and the central angle of the first semi-ring track 41 and the second semi-ring track 42 is 180 degrees. In other embodiments, the corresponding central angle may be less than 180 degrees.

[0039] Optional, see Figure 3 The driving assembly 3 is used to drive the first semi-ring track 41 and the second semi-ring track 42 to move along the length direction of the receiving portion 2. The driving assembly 3 includes a driving motor 31, a slider 32, a screw rod 33 and a guide rod 34. The top wall of the first semi-ring track 41 and the bottom of the second semi-ring track 42 are fixedly provided with the slider 32. The screw rod 33 is threadedly penetrated in the slider 32. The screw rod 33 is arranged along the length direction of the receiving portion 2. The guide rod 34 is slidably penetrated on both sides of the first semi-ring track 41 and the second semi-ring track 42. The two ends of the screw rod 33 and the guide rod 34 are fixedly connected with the annular plate 12, and the annular plate 12 is arranged on the frame 1. The driving motor 31 is fixedly arranged on the annular plate 12, and the output shaft of the driving motor 31 is fixedly connected with the screw rod 33. The driving motor 31 is a servo motor. During detection, the drive motor 31 is started, the drive motor 31 drives the screw rod 33 to rotate, and the screw rod 33 drives the first half-ring track 41 or the second half-ring track 42 to slide along the length direction of the beam 10 to complete the detection of the beam 10.

[0040] The distance between the two annular plates 12 is greater than the length of the beam 10 to ensure that the beam 10 is located between the two annular plates 12 during detection, so that the first semi-annular track 41 and the second semi-annular track 42 can move along the length direction of the side plate 21 The distance is greater than the length of the beam 10, so as to improve the detection quality of the beam 10.

[0041] Optional, see Figure 3 The lifting component is arranged on the frame 1 to drive the first semi-ring track 41 to rise and fall. The lifting component includes a lifting cylinder 11. In the present embodiment, four lifting cylinders 11 are arranged. The lifting cylinders 11 are vertically fixed on the frame 1. The piston rods of the lifting cylinders 11 are fixedly connected to the two annular plates 12 corresponding to the first semi-ring track 41, and the four lifting cylinders 11 are respectively connected to the two ends of the two annular plates 12 to ensure the stable lifting of the first semi-ring track 41.

[0042] Optional, see Figure 3 and Figure 4 The detection module 7 is used to detect welding defects of the beam 10. The detection module 7 is arranged on the first semi-ring track 41 and the second semi-ring track 42, and can move along the first semi-ring track 41 and the second semi-ring track 42.

[0043] Specifically, refer to Figure 3 and Figure 4 The detection module 7 includes a moving seat 71 and a camera module 72. The detection module 7 is disposed on both the first semi-circular track 41 and the second semi-circular track 42. The moving seat 71 can move along the first semi-circular track 41 or the second semi-circular track 42. The camera module 72 is disposed on the moving seat 71 for photographing the weld of the beam 10. The camera module 72 can be an industrial high-speed camera for dynamic monitoring and capturing microscopic details of the weld (such as cracks, pores, unfused defects, etc.). The detection module 7 also includes an image processing module for real-time processing of image data and application of algorithms (such as edge detection, grayscale analysis, and deep learning) to identify defects.

[0044] Reference Figure 4 The moving seat 71 is provided with a walking mechanism, which includes a servo motor and rollers. Annular grooves 43 are provided on both sides of the first semi-ring track 41 and the second semi-ring track 42. The rollers are arranged to roll in the annular grooves 43, and the rollers are arranged to rotate in the moving seat 71. The servo motor is fixed in the moving seat 71, and the output shaft of the servo motor is connected to the rollers. The servo motor is used to drive the rollers to rotate, and the rollers move along the annular track, thereby driving the moving seat 71 to move along the first semi-ring track 41 or the second semi-ring track 42.

[0045] Reference Figure 4 The moving seat 71 is provided with a moving block 711, which can move radially along the first semi-ring track 41 or the second semi-ring track 42. The moving seat 71 is provided with a driving member for driving the moving block 711 to move, and the camera module 72 is provided on the moving block 711. In this embodiment, the driving member is a driving cylinder 712, which is fixedly arranged on the moving seat 71 along the radial direction of the first semi-ring track 41 or the second semi-ring track 42, and the moving block 711 is fixedly arranged on the piston rod of the driving cylinder 712.

[0046] During the detection process, for some unclear positions, the driving member can drive the moving block 711 to move closer to the beam 10, thereby shortening the distance between the camera module 72 and the beam 10 and improving the detection accuracy. In addition, because some truck beams 10 have curved sections, when the detection module 7 moves to this position, the detection module 7 moves in a circle, and the detection module 7 on one side is farther away from the beam 10, while when it rotates to the other side, it is closer to the beam 10 and even interferes with the beam 10; at this time, the driving member can drive the moving block 711 to move, so as to ensure that the distance between the camera module 72 and the beam 10 remains constant, improve the detection quality, and prevent the curved part from interfering with the movement of the camera module 72.

[0047] Optional, see Figure 4Two positioning blocks 8 are slidably disposed on the first half-ring track 41 and the second half-ring track 42. The two positioning blocks 8 are respectively located on both sides of the detection module 7. A travel switch is disposed on the positioning block 8. The travel switch is electrically connected to the servo motor on the moving seat 71. When the moving seat 71 moves to the travel switch and contacts the travel switch, the circuit state changes to control the servo motor to rotate in the opposite direction, so that the moving seat 71 reciprocates between the two positioning blocks 8.

[0048] Reference Figure 4 and Figure 5 The positioning block 8 is provided with a limiting member for limiting the position of the positioning block 8. The limiting member is a limiting bolt 81. The limiting bolt 81 is threadedly arranged in the side wall of the positioning block 8 and is used to abut against the side wall of the first semi-ring track 41 or the second semi-ring track 42 to limit the positioning block 8. The positioning block 8 is provided with a laser positioning member 82. The laser direction of the laser positioning member 82 faces the beam 10. The laser positioning member 82 can be a laser indicator that can emit a visible laser beam. By adjusting the position between the two positioning blocks 8, it can adapt to beams 10 of different sizes and improve applicability.

[0049] The angle formed by the two welds inside the beam 10 and the extended lines of the edges of the two wing panels is the maximum detection angle range of the detection module 7. Figure 5 As shown, the angle between the laser lines emitted by the two laser positioning members is the maximum angle range. During the detection process, when the moving seat 71 contacts the two travel switches, the moving direction of the moving seat 71 will be changed, that is, the moving range of the moving seat 71 is between the two travel switches, and there is no need to move to the entire first semi-ring track 41 or the second semi-ring track 42, which reduces the moving distance of the moving seat 71, shortens the circumferential detection time of the beam 10, and improves the detection efficiency.

[0050] Optional, see Figure 4 A blowing assembly is provided on the movable seat 71, and the blowing assembly includes an air nozzle 91, an air pipe 92 and an air pump 93. The air nozzle 91 is provided on the movable block 711, and the air nozzle 91 is radially arranged along the first semi-ring track 41 or the second semi-ring track 42, so that the airflow of the air nozzle 91 is ejected toward the beam 10; the air pump 93 is provided on the movable seat 71, and one end of the air pipe 92 is connected to the output end of the air pump 93, and the other end is connected to the air nozzle 91.

[0051] There may be welding smoke or dust in the workshop. During the inspection process, if the air pump 93 pumps air to the air nozzle 91 through the air pipe 92, the air nozzle 91 blows air toward the beam 10, thereby blowing away the smoke or dust in the air between the camera module 72 and the beam 10, and at the same time cleaning the dust on the beam 10, so that the camera module 72 can more clearly capture the weld of the beam 10, thereby improving the inspection effect.

[0052] The implementation principle of the embodiment of the present application is as follows: the I-shaped beam 10 includes an upper wing plate, a lower wing plate and a waist plate, the upper wing plate and the lower wing plate are parallel, and the waist plate is connected to the upper wing plate and the lower wing plate respectively. The weld is located at the connection between the waist plate and the upper wing plate and the lower wing plate. The welded truck beam 10 is moved from one side of the receiving part 2 to the receiving part 2, and the waist plate of the beam 10 is kept in a horizontal state, so that the two openings of the I-shaped beam 10 are just facing upward and downward, so that the detection module 7 does not need to move the entire circumference, and can shoot and detect the weld inside the I-shaped beam, thereby improving the detection efficiency.

[0053] The first semi-ring track 41 is driven downward to approach the second semi-ring track 42 by the lifting component. When the detection module 7 detects the welding seam of the beam 10, the detection module 7 moves along the first semi-ring track 41 and the second semi-ring track 42, so that the circumferential direction of the beam 10 can be detected by the detection module 7; at the same time, the first semi-ring track 41 and the second semi-ring track 42 are driven by the driving component 3 to move along the length direction of the supporting part 2 to complete the detection of the entire beam 10.

[0054] After the inspection is completed, the first half-ring track 41 is driven upward by the lifting assembly, and then the beam 10 is removed from the other side of the receiving portion 2. The space occupied by the entire device is equivalent to the length of the beam 10, which effectively reduces the space occupied by the workshop; and there is no need to turn over the beam 10 during the entire inspection process, which is convenient for inspection.

[0055] The embodiment of the present application also discloses a method for detecting welding defects of a truck beam.
