[0002] In the automotive industry, the quality of the lower trim strips for car windows is a crucial decorative component, directly impacting the overall aesthetics and quality of the vehicle. With increasingly fierce competition in the automotive market, consumers are demanding higher and higher levels of vehicle exterior quality, making high-quality lower trim strips even more critical.

While some solutions using automated inspection equipment have improved inspection efficiency and accuracy to a certain extent, they lack effective marking methods after detecting damage on the bright strip surface. This makes it difficult for operators to quickly and accurately locate the damaged area in subsequent production processes, increasing the difficulty and time cost of handling defective products.

When the defect marking operation is performed, the lighting tube is cleaned simultaneously to ensure that the lighting effect is always good during the inspection process.

[0017] The present invention provides a device for detecting the bright strip under the triangular window of an automobile. It has the following beneficial effects:

[0018] (1) The device drives the forward and reverse screws to rotate by setting a driving motor. The rotation of the forward and reverse screws causes the adjustment frame to move linearly along the forward and reverse screws. As the adjustment frame moves, the movable rod rotates, thereby driving the two guide plates on the top of the conveyor belt to move closer to or away from each other. At the same time, the guide frame and the tension spring can ensure the stability of the guide plate movement, thereby enabling the detection device to adapt to bright strips of various widths.

[0019] (2) The device is provided with a scale groove. The scale fixed to the top of the guide plate cooperates with the scale groove opened in the protective shell wall. The operator can accurately adjust the position of the guide plate according to the scale groove to adapt to the different widths of the car's triangular window lower bright strips, ensuring that the bright strips can be accurately transported to the detection position, thereby improving the stability and consistency of the detection results, reducing the detection deviation caused by the difference in the position of the bright strips, and ensuring the accuracy and validity of the detection data.

[0020] (3) The device is provided with a liquid guide component. When scratches, pits, cracks and other damages are detected on the surface of the bright strip, the electric push rod drives the liquid guide component to move downward. At this time, the sliding ring slides downward along the inner side of the mounting shell, and the sealing ring slides downward along the surface of the hollow guide column. At this time, the through hole is separated from the inner side of the sealing ring, and the ink flowing from the ink storage cartridge into the hollow guide column can flow into the surface of the sliding ring through the through hole, and then flow to the thinner diameter part of the hollow guide column through the guide groove. After that, it can be immersed in the rubbing plate through the liquid guide ring to provide sufficient ink for marking.

[0021] (4) The device is provided with a rubbing plate. The mounting cylinder will move downward along with the sliding ring, driving the liquid guide ring and the rubbing plate. At this time, the rubbing plate can print ink on the damaged part of the bright strip surface and mark the outside of the damaged part with a ring mark. In the subsequent production process, the operator can intuitively see which parts of the bright strip surface have scratches, pits or cracks, without having to use complex detection equipment to find the damage points, which greatly improves the efficiency of subsequent processing of defective products.

[0022] (5) The device is provided with an annular baffle, the top of which is fixed to the mounting shell. When the mounting cylinder moves downward, the annular baffle gradually slides out of the mounting cylinder, thereby preventing the ink from contacting the detection probe when entering the mounting shell. When the electric push rod drives the sliding ring to reset, the inner side of the sealing ring contacts the surface of the hollow guide column again and blocks the through hole, thereby blocking the flow path of the ink and realizing ink supply on demand, avoiding the waste of ink when the ink mark is not needed, resulting in excessive marking.

[0023] (6) The device is equipped with lighting components. When the bright strip passes through the protective shell, the lighting components fixed on both sides of the shell are installed to operate synchronously. The lighting tube can provide good lighting conditions for the detection probe, facilitating clearer detection of the bright strip.

[0024] (7) The device is provided with a rubber wiping plate. As the connecting block moves, a negative pressure state is formed in the bent pipe, forcing the limit block to slide to the side close to the bent pipe. At this time, the inclined surface on the top of the limit block and the inclined surface on the bottom of the sliding block slide against each other. Under the action of the spring, the sliding block gradually drives the rubber wiping plate to press on the top of the lighting tube. At this time, the adjustment motor drives the guide roller to rotate. While the guide roller rotates, the lighting tube can rotate along the inner side of the mounting frame, so that the rubber wiping plate can wipe and clean the surface of the rotating lighting tube in all directions.

[0025] (8) This device utilizes a connecting block, and the downward movement of the liquid guide ring typically occurs when a defect in the bright strip is detected and needs to be marked. During defect marking, the connecting block and the liquid guide ring move synchronously, ultimately cleaning the lighting tube, ensuring optimal lighting throughout the inspection process. During the marking process, the inspection is complete, and changes in the lighting tube state will not affect the obtained test results, effectively ensuring the accuracy of the inspection.

[0042] The lighting assembly 63 includes a mounting frame 631, a sliding block 632 is slidably connected to the inner side of the mounting frame 631, a rubber wiper 633 is fixedly connected to the bottom of the sliding block 632, a lighting tube 634 is rotatably connected to the rubber wiper 633, and springs 630 are fixedly connected to both sides of the sliding block 632.

During the downward movement of the liquid guide ring 654, the connecting block 639 moves downward synchronously. At this time, as the connecting block 639 moves, a negative pressure state is formed in the curved tube 638, forcing the limit block 637 to slide to the side close to the curved tube 638.

The downward movement of the liquid guide ring 654 is usually an action when a defect in the bright strip is detected and needs to be marked. When marking defects, the lighting tube 634 is cleaned simultaneously to ensure that the lighting effect is always good during the inspection process. During the marking process, the inspection is completed at this time, and the change in the state of the lighting tube 634 will not affect the obtained inspection results, which can effectively ensure the accuracy of the inspection.

[0043] Working principle: This device is mainly used to detect the bright strips under the car's triangular windows. The detection mechanism 6 is used to detect surface defects (such as scratches, pits, cracks, etc.) of the bright strips, and the guide plate 11 can be adjusted according to the different sizes of the bright strips.

[0044] When it is necessary to inspect the lower bright strip of the automobile triangular window, a motor is installed on the outside of the frame 1 so that it can drive any one of the two rollers 2 located on both sides of the frame 1 to rotate. The rotation of the roller 2 drives the conveyor belt 3 to operate, and the lower bright strip of the automobile triangular window placed on the conveyor belt 3 can be transported to the inspection area inside the protective shell 4.

[0045] During this process, by starting the driving motor 7, it drives the forward and reverse screw rods 8 to rotate. The rotation of the forward and reverse screw rods 8 will cause the adjusting frame 9 to move linearly along the forward and reverse screw rods 8. As the adjusting frame 9 moves, the movable rod 10 rotates, thereby driving the two guide plates 11 at the top of the conveyor belt 3 to move closer to or away from each other. At the same time, the guide frame 12 and the tension spring 13 can ensure the stability of the movement of the guide plate 11, thereby enabling the detection device to adapt to bright strips of various widths and specifications, and allowing the bright strips to pass directly under the detection mechanism 6 car.

[0046] The scale 14 fixedly connected to the top of the guide plate 11 cooperates with the scale groove 15 opened in the wall of the protective shell 4. The operator can accurately adjust the position of the guide plate 11 according to the scale groove 15 to adapt to the bright strips under the car triangular windows of different widths, ensuring that the bright strips can be accurately transported to the detection position, thereby improving the stability and consistency of the detection results, reducing the detection deviation caused by the difference in the position of the bright strips, and ensuring the accuracy and effectiveness of the detection data.

[0047] When the detection mechanism 6 is working, after the bright strip is transported to the detection position, the telescopic cylinder 5 fixedly connected to the top of the protective shell 4 is started, and the piston rod of the telescopic cylinder 5 extends downward, driving the detection mechanism 6 fixedly connected to the bottom to descend as a whole, so that the detection mechanism 6 is close to the bright strip. At this time, the mounting shell 61 drives the fixing cylinder 62 to descend synchronously, and the detection probe 66 descends synchronously to detect the bright strip, thereby obtaining relevant data of the bright strip.

[0048] When scratches, pits, cracks and other damage are detected on the surface of the bright strip, the electric push rod 64 drives the liquid guide assembly 65 to move downward. At this time, the sliding ring 651 slides downward along the inner side of the mounting shell 61, and the sealing ring 657 slides downward along the surface of the hollow guide column 656. At this time, the through hole 659 is separated from the inner side of the sealing ring 657, and the ink flowing from the ink storage cartridge 67 into the hollow guide column 656 can flow into the surface of the sliding ring 651 through the through hole 659, and then flow to the thinner diameter part of the hollow guide column 656 through the guide groove 658, and then can be immersed in the rubbing plate 655 through the liquid guide ring 654.

[0049] During this process, the installation cylinder 652 will move downward together with the sliding ring 651, driving the liquid guide ring 654 and the rubbing plate 655. At this time, the rubbing plate 655 can print ink on the damaged part of the surface of the bright strip, and mark the outside of the damaged part with a ring mark. In the subsequent production process, the operator can intuitively see which parts of the surface of the bright strip have scratches, pits or cracks, without having to use complex detection equipment to find the damage points, which greatly improves the efficiency of subsequent processing of defective products.

[0050] The top of the annular baffle 653 is fixed to the mounting shell 61. When the mounting cylinder 652 moves downward, the annular baffle 653 gradually slides out of the mounting cylinder 652, thereby preventing the ink from contacting the detection probe 66 when entering the mounting shell 61. When the electric push rod 64 drives the sliding ring 651 to reset, the inner side of the sealing ring 657 contacts the surface of the hollow guide column 656 again and blocks the through hole 659, thereby blocking the flow path of the ink, realizing on-demand ink supply, and avoiding the waste of ink when the ink mark is not needed, resulting in an overly heavy mark.

[0051] When the bright strip passes through the protective shell 4, the lighting components 63 fixedly connected on both sides of the mounting shell 61 work synchronously. The lighting tube 634 can provide good lighting conditions for the detection probe 66, making it easier to detect the bright strip.

[0052] As the liquid guide ring 654 moves downward, the connecting block 639 moves downward synchronously. At this time, as the connecting block 639 moves, a negative pressure state is formed in the curved pipe 638, forcing the limit block 637 to slide to the side close to the curved pipe 638. At this time, the inclined surface at the top of the limit block 637 and the inclined surface at the bottom of the sliding block 632 slide against each other. Under the action of the spring 630, the sliding block 632 gradually drives the rubber wiping plate 633 to press on the top of the lighting tube 634. At this time, the adjusting motor 635 drives the guide roller 636 to rotate. While rotating, the guide roller 636 can make the lighting tube 634 rotate along the inner side of the mounting bracket 631, so that the rubber wiping plate 633 can wipe and clean the surface of the rotating lighting tube 634 in all directions.

[0053] The downward movement of the liquid guide ring 654 typically occurs when a defect in the bright strip is detected and needs to be marked. During defect marking, the lighting tube 634 is cleaned simultaneously to ensure optimal lighting throughout the inspection process. By wiping the light during the marking process, the inspection is complete, and changes in the state of the lighting tube 634 will not affect the obtained test results, effectively ensuring inspection accuracy.
