Detailed implementation manners

[0025] The following will Figures 1-8 further elaborate on the present invention in detail.

[0026] Embodiment 1:

[0027] An embodiment of the present invention discloses an automatic welding detection system in automobile production. Referring to Figure 1 , the automatic welding detection system in automobile production includes a detection cover 1, a detection mechanism, an illumination mechanism, and a clamping mechanism 2; the lower end of the detection cover 1 has a plurality of support rods 22 to fixedly install the detection cover 1 at the welding site in automobile production, and both the bottom wall and one side wall of the detection cover 1 have openings 23 to facilitate the transfer of automobile parts into or out of the detection cover 1; the detection mechanism is arranged inside the detection cover 1 and is used to detect whether there are any missed welds on the parts of the automobile parts; the illumination mechanism is arranged inside the detection cover 1 and is used to provide illumination inside the detection cover 1; the clamping mechanism 2 is used to clamp the automobile parts and move them into or out of the detection cover 1.

[0028] During operation, the welded automobile parts are moved into the detection cover 1 through the clamping mechanism 2, and the inside of the detection cover 1 is illuminated by the illumination mechanism, which helps to ensure that the brightness of the automobile parts is consistent during detection. Then, the detection mechanism is used to detect whether there are any missed welds on the parts of the automobile parts. If there are missed welds on the parts, the clamping mechanism 2 will return the automobile parts to the welding station for re-welding. If there are no missed welds, the clamping mechanism 2 will move the automobile parts to the conveyor belt for the next process, thereby helping to timely determine whether there are any missed welds on the body parts after welding and ensuring the quality of the welded products to a certain extent. In the embodiment of the present invention, it mainly judges whether there are any missed welds on the parts such as screws and bolts on the vehicle floor.

[0029] Referring to Figure 1, for facilitating lighting inside the detection cover 1, the lighting mechanism includes multiple lamps 21. The multiple lamps 21 are respectively installed on opposite sides inside the detection cover 1, and there are multiple lamps 21 distributed on each side. The number and positions of the lamps 21 can be set according to needs. With the multiple lamps 21, it helps to ensure that the brightness of automotive parts is consistent during detection and is not easily affected by natural light factors, thus not affecting the detection accuracy.

[0030] Refer to Figure 1 , for facilitating the detection of automotive parts, the clamping mechanism 2 uses a mechanical gripper. The mechanical gripper belongs to the prior art, and its specific structure and principle will not be elaborated here. The mechanical gripper is located at the position of the side opening 23 of the detection cover 1, so as to facilitate clamping and moving the welded automotive parts into the detection cover 1 for detection or moving the detected automotive parts out of the detection cover 1.

[0031] Refer to Figure 1 , Figure 2 and Figure 3 , for facilitating the detection of whether there are any missed welds on the parts of the workpiece, a support frame 4 is fixedly installed inside the detection cover 1. The support frame 4 is of a portal structure. The detection mechanism includes a control platform, a mounting frame, and multiple cameras 3. The control platform is arranged outside the detection cover 1 and is a PLC control platform. The mounting frame is arranged on the support frame 4, and multiple cameras 3 are all installed on the mounting frame. Specifically, an adjustment bracket 20 is fixedly suspended on the mounting frame, and the adjustment bracket 20 corresponds to the camera 3 one by one. The camera 3 is fixedly installed on the corresponding adjustment bracket 20. The adjustment bracket 20 can adjust the angle and position of the corresponding camera 3 according to needs. Specifically, the adjustment bracket 20 includes multiple adjustment rods connected to each other through a ball joint or a ball head joint, and the ball joints between the adjustment rods are fixed by screws or bolts, thereby realizing the adjustable performance of the adjustment bracket 20. The multiple cameras 3 have the same inclination direction, and the cameras 3 are wirelessly connected to the control platform. The control platform is wirelessly connected to the mechanical gripper. The cameras 3 are used to take pictures of different positions of the automotive parts and send them to the control platform. The control platform is used to receive and identify the pictures taken by the cameras 3 and compare them with the preset pictures to determine whether there are any missed welds on the parts of the automotive parts. Among them, the preset picture is a picture of the parts on the automotive part being welded completely. By automatically identifying the pictures taken by the cameras 3 through the control platform, it helps to realize the automatic detection of production, improve production efficiency and automation level.

[0032] During the inspection, the automobile parts are moved to the bottom of the multiple cameras 3 on the mounting frame by the mechanical gripper, and the automobile parts are close to the multiple cameras 3. The multiple cameras 3 take pictures of different positions of the automobile parts and send them to the control platform. The control platform receives and identifies the pictures taken by the cameras 3 and compares them with the preset pictures, so as to determine whether there is a welding leak on the parts of the automobile parts. If there is a welding leak, the mechanical gripper returns the automobile parts to the welding station for repair welding. If there is no welding leak, the mechanical gripper moves the automobile parts to the conveyor belt for the next process, thereby ensuring the quality of the welding products to a certain extent. There are multiple cameras 3. On the one hand, due to the focal length limitation of the camera 3, the multiple cameras 3 can take clear pictures of different positions of the automobile parts; on the other hand, by adjusting the bracket 20 to adjust the angle and position of the camera 3 at different positions, it is helpful to adapt to the special-shaped automobile parts and reduce the error caused by reflection.

[0033] Reference Figure 1 and Figure 2 In order to facilitate the detection of both sides of the automobile parts, lifting seats 5 are slidably arranged on the opposite sides of the support frame 4. The lifting seats 5 are slidably arranged in the vertical direction. The arrangement direction of the lifting seats 5 on both sides is parallel to the plane where the side opening 23 of the detection cover 1 is located. Specifically, each lifting seat 5 is slidably matched with the guide rail on the support frame 4, so that the lifting seat 5 will not be separated from or deviated from the support frame 4; a rotating rod 7 is arranged between the lifting seats 5 on both sides, and the mounting frame is arranged on the rotating rod 7 between the two lifting seats 5. The support frame 4 is provided with a driving member 6 for driving the lifting seats 5 on both sides to move.

[0034] Reference Figure 2 and Figure 4 In order to facilitate the synchronous movement of the lifting seats 5 on both sides, the driving member 6 includes a driving motor 61, a driving rod 62, a sprocket 63, a chain 64 and a counterweight seat 65. The driving motor 61 is fixedly mounted on the top of the support frame 4, and the driving rod 62 is rotatably arranged on the support frame 4. The rotation axis of the driving rod 62 is parallel to the arrangement direction of the two lifting seats 5. The driving rod 62 is coaxially fixed with the output end of the driving motor 61, and the driving rod 62 is located above the mounting frame; the sprocket 63 is fixedly sleeved on the driving rod 6 2, and the sprocket 63 corresponds to the lifting seat 5 one by one, the chain 64 corresponds to the sprocket 63 one by one, the chain 64 is engaged with the corresponding sprocket 63, the counterweight seat 65 corresponds to the lifting seat 5 one by one, the counterweight seat 65 is slidably connected to the support frame 4 along the vertical direction, and the counterweight seat 65 is located on the side of the support frame 4 away from the corresponding lifting seat 5, one end of the chain 64 is fixedly connected to the corresponding lifting seat 5, and the other end is fixedly connected to the corresponding counterweight seat 65, and the driving motor 61 is wirelessly connected to the control platform.

[0035] After the inspection of one side of the automotive component is completed, the drive motor 61 is started. The drive motor 61 drives the drive rod 62 to drive the sprocket 63 to rotate. The sprocket 63 drives the corresponding chain 64 to convey towards the direction of the counterweight seat 65. At this time, the chain 64 on both sides of the lifting seat 5 pulls the lifting seat 5 to drive the mounting bracket and the camera 3 to move upward. The chain 64 remains in an extended state under the gravity of the counterweight seat 65. Then, the automotive component is turned over by the mechanical gripper, so as to provide sufficient space for turning over the automotive component. After the automotive component is turned over, the drive motor 61 drives the drive rod 62 to rotate in the reverse direction, so that the chain 64 conveys towards the direction close to the lifting seat 5. Under the gravity of the lifting seat 5 and the mounting bracket, the multiple cameras 3 move downward to approach the automotive component, and then the other side of the automotive component can be photographed and recognized to facilitate the inspection of the welding condition of the other side of the automotive component.

[0036] Referring to Figure 2 and Figure 4 , for facilitating the adjustment of the angle of the camera 3 (referring to Figure 3 ), the rotating rod 7 is rotatably arranged between the two lifting seats 5. The rotation axis of the rotating rod 7 is parallel to the arrangement direction of the two lifting seats 5. A drive source 8 for driving the rotating rod 7 to rotate is fixedly installed on the lifting seat 5. Specifically, the drive source 8 includes a stepping motor fixedly installed on any one side of the lifting seat 5. The rotating rod 7 is coaxially fixed with the output shaft of the stepping motor. In other embodiments, the stepping motor can be replaced by a servo motor, a drive motor, etc.

[0037] By starting the drive source 8 to drive the rotating rod 7 to rotate, the rotating rod 7 drives the mounting bracket to rotate, so that the angles of all the cameras 3 can be adjusted as needed to facilitate the inspection of the welding condition of the automotive component with a special-shaped inclined surface.

[0038] Referring to Figure 2 and Figure 4 , further, for facilitating the installation of the camera 3 (referring to Figure 3 ), the mounting bracket includes a plurality of mounting plates 9. The plurality of mounting plates 9 are fixedly spaced on the rotating rod 7. The arrangement direction of the plurality of mounting plates 9 is parallel to the rotation axis of the rotating rod 7. The mounting plate 9 is made of angle steel. The adjusting brackets 20 of the plurality of cameras 3 are respectively fixed on the mounting plates 9. Specifically, cameras 3 are distributed at both ends of each mounting plate 9. In other embodiments, the number and positions of the cameras 3 can be set as needed.

[0039] The implementation principle of Embodiment 1 of the present invention is as follows: During operation, the welded automotive component is moved into the detection cover 1 by a mechanical gripper, such that the automotive component is located below multiple cameras 3. Multiple lamps 21 inside the detection cover 1 are turned on to illuminate the automotive component, which helps ensure the brightness of the automotive component during detection. Then, the drive motor 61 is started to drive the drive rod 62 to rotate, causing the chain 64 to be conveyed towards the direction close to the lifting seat 5. Under the gravitational action of the lifting seat 5 and the mounting frame, the multiple cameras 3 move downward close to the automotive component. Then, the multiple cameras 3 take pictures of different positions on the upper surface of the automotive component at this time and send them to the control platform. The control platform receives and identifies the pictures taken by the cameras 3 and compares them with the preset pictures, thereby determining whether there are any missed welds on the parts of the automotive component.

[0040] When one side of the automotive component is detected, the drive motor 61 is started. The drive motor 61 drives the drive rod 62 to drive the sprocket 63 to rotate, and the sprocket 63 drives the corresponding chain 64 to be conveyed towards the direction of the counterweight seat 65. At this time, the lifting seat 5 is pulled by the chains 64 on both sides to drive the mounting frame and the cameras 3 to move upward, providing sufficient space for turning over the automotive component. Then, the mechanical gripper is used to turn over the automotive component. After the turning over is completed, the drive motor 61 drives the drive rod 62 to rotate in the reverse direction, causing the chain 64 to be conveyed towards the direction close to the lifting seat 5. Under the gravitational action of the lifting seat 5 and the mounting frame, the multiple cameras 3 move downward close to the automotive component, and then pictures can be taken of the other side of the automotive component, thereby realizing the detection of the welding condition of the other side of the automotive component. If there are missed welds on the automotive component, the mechanical gripper returns the automotive component to the welding station for re-welding. If there are no missed welds on the automotive component, the mechanical gripper moves the automotive component to the conveyor belt for the next process, which helps timely determine whether there are missed welds of parts such as bolts and screws on the body components after welding, and ensures the quality of the welded products to a certain extent.

[0041] Embodiment 2:

[0042] Refer to Figure 5 and Figure 6, the difference between the embodiment of the present invention and Embodiment 1 is that the mounting bracket includes a first support plate 10, a fixed group and a movable group. The first support plate 10 is fixedly arranged below the rotating rod 7. Both the fixed group and the movable group are located on the side of the first support plate 10 away from the rotating rod 7. Among them, the fixed group includes a plurality of first mounting strips 11 arranged at intervals. The arrangement direction of the plurality of first mounting strips 11 is parallel to the rotation axis of the rotating rod 7. A first synchronous connection plate 13 is fixedly connected by the plurality of first mounting strips 11. The length direction of the first mounting strip 11 is perpendicular to the rotation axis of the rotating rod 7. The first synchronous connection plate 13 is located on the side of the first mounting strip 11 away from the center of the first support plate 10. The first synchronous connection plate 13 is fixedly hoisted below the first support plate 10 by a plurality of suspension rods 24, so that the first mounting strip 11 is relatively fixed to the first support plate 10.

[0043] Refer to Figure 6 and Figure 7 , the movable group includes a plurality of second mounting strips 12 arranged at intervals. The arrangement direction of the plurality of second mounting strips 12 is parallel to the rotation axis of the rotating rod 7. The movable group is located on the side of the first mounting strip 11 away from the first synchronous connection plate 13. A second synchronous connection plate 14 is fixedly connected to the side of the plurality of second mounting strips 12 close to the first mounting strip 11. A plurality of sliding rods 15 are fixed on the second synchronous connection plate 14. The sliding rods 15 slidably penetrate through the first support plate 10. The sliding direction of the sliding rods 15 is perpendicular to the plane where the first support plate 10 is located. The adjusting brackets 20 of the camera 3 are respectively fixedly arranged on the first mounting strip 11 and the second mounting strip 12, so that two rows of cameras 3 are installed on both sides below the first support plate 10; an adjusting member is arranged on the first support plate 10, and the adjusting member is used to adjust the plurality of second mounting strips 12 to slide synchronously in a direction close to or away from the first support plate 10.

[0044] Refer to Figure 5 , Figure 7 and Figure 8 , to facilitate the synchronous sliding of the plurality of second mounting strips 12 in a direction close to or away from the first support plate 10, the adjusting member includes a spring 16, a first telescopic rod 17, a second support plate 18 and a second telescopic rod 19. The springs 16 correspond to the sliding rods 15 one by one. The spring 16 is sleeved on the corresponding sliding rod 15 and is located at the end of the sliding rod 15 away from the second synchronous connection plate 14. One end of the spring 16 is fixed on the side of the first support plate 10 close to the rotating rod 7, and the other end is fixed on the side of the sliding rod 15 away from the second synchronous connection plate 14.

[0045] Refer to Figure 6 and Figure 7, One end of the first telescopic rod 17 is hinged to the second synchronous connecting plate 14, and the other end is hinged to the first synchronous connecting plate 13. The hinge axis of the first telescopic rod 17 is parallel to the rotation axis of the rotating rod 7, and the telescopic direction of the first telescopic rod 17 is perpendicular to the rotation axis of the rotating rod 7. A plurality of first telescopic rods 17 are distributed along the rotation axis direction of the rotating rod 7. The first telescopic rod 17 and the first mounting strip 11 are arranged in a staggered manner so that the first telescopic rod 17 and the first mounting strip 11 will not interfere with each other.

[0046] Refer to Figure 5 , Figure 6 and Figure 7 , The second support plate 18 is fixed between the two lifting seats 5. The rotating rod 7 is located between the first support plate 10 and the second support plate 18. The second telescopic rods 19 correspond to the first telescopic rods 17 one by one. The second telescopic rods 19 slidably pass through the first support plate 10. Through holes 25 for the first telescopic rods 17 to move are formed in the first support plate 10. The diameter of the through holes 25 is larger than the maximum diameter of the second telescopic rods 19. One end of the second telescopic rod 19 is fixed to the second support plate 18, and the other end is fixed to the end of the corresponding first telescopic rod 17 close to the first synchronous connecting plate 13. The telescopic direction of the second telescopic rod 19 is arranged in the vertical direction, and the telescopic direction of the first telescopic rod 17 is parallel to the arrangement direction of the fixed group and the movable group. When the first support plate 10 is in the initial state, it is in a horizontal state; the rotation angle of the rotating rod 7 driving the first support plate 10 is less than 30°.

[0047] The implementation principle of Embodiment 2 of the present invention is as follows: When the driving source 8 drives the rotating rod 7 to drive the first support plate 10 to rotate so that the side of the first support plate 10 close to the fixed group is inclined downward, since the first synchronous connecting plate 13 and the second synchronous connecting plate 14 will be located on different horizontal planes under the rotation of the first support plate 10, then the first synchronous connecting plate 13 will drive the ends of the plurality of first telescopic rods 17 to move downward. Since the first telescopic rod 17 is hinged to the first synchronous connecting plate 13, the first synchronous connecting plate 13 can change the angle with the first telescopic rod. The first telescopic rod 17 maintains a horizontal state under the guidance of the second telescopic rod 19. Then, while the end of the first telescopic rod 17 far from the first synchronous connecting plate 13 drives the second synchronous connecting plate 14 to move downward, it extends. The second synchronous connecting plate 14 drives the plurality of second mounting strips 12 and the sliding rods 15 of the movable group to move in a direction away from the first support plate 10. Since the sliding rods 15 move, the position change between the second synchronous connecting plate 14 and the first synchronous connecting plate 13 can be adapted, so that the plurality of cameras 3 on the second mounting strip 12 move in a direction away from the first support plate 10, so that even though the first mounting strip 11 and the second mounting strip 12 are synchronously inclined, the height difference between the cameras 3 of the fixed group and the cameras 3 of the movable group can be reduced, ensuring that the photographing distance of the cameras 3 on the movable group from the automotive parts will not be too far, and it is applicable to the special-shaped surfaces of automotive parts with multiple identical inclined surfaces.

[0048] Similarly, when the driving source 8 drives the rotating rod 7 to drive the first support plate 10 to rotate, and the side of the first support plate 10 close to the fixed group tilts upward, the first synchronous connection plate 13 will drive the ends of the plurality of first telescopic rods 17 to move upward. Then, the end of the first telescopic rod 17 away from the first synchronous connection plate 13 drives the second synchronous connection plate 14 to move upward and the first telescopic rod 17 extends. The second synchronous connection plate 14 drives the plurality of second mounting bars 12 and the sliding rod 15 of the movable group to move in the direction close to the first support plate 10, so that the plurality of cameras 3 on the second mounting bar 12 move in the direction close to the first support plate 10, so that even though the first mounting bar 11 and the second mounting bar 12 are synchronously and reversely tilted, the distance between the cameras 3 of the fixed group and the cameras 3 of the movable group from the automotive component can be close, ensuring that the photographing distance of the cameras 3 on the fixed group from the automotive component will not be too far.

[0049] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
