Description

Technical Field

[0001] This invention relates to the field of laser inspection and processing technology for automotive sunroof sealing strips, and particularly to a laser inspection device for automotive sunroof sealing strips. Background Technology

[0002] As a core feature enhancing driving comfort and vehicle prestige, the sunroof's sealing performance directly determines the vehicle's waterproofing, dustproofing, sound insulation, and heat insulation effects. The sunroof sealing strip, a key component for achieving this sealing function, is the core carrier ensuring the reliability of the sunroof system. This sealing strip is typically molded from a single piece using elastic materials such as rubber and silicone. Its structure includes complex and irregular features such as sealing lips, mounting grooves, and reinforcing ribs. It must simultaneously meet three core quality requirements: dimensional accuracy, surface integrity, and assembly fit. Excessive dimensional deviations can lead to uneven assembly gaps, causing rainwater leakage or sunroof opening / closing difficulties. Therefore, quality inspection of the sunroof sealing strip is an indispensable and crucial process in automotive parts production and vehicle assembly. To address this, patent CN117990032B discloses a sealing strip contour detector, comprising a machine base and a detector body. The detector body is slidably mounted on the machine base, on which a conveyor belt for conveying sealing strips is installed. The detector probe of the detector body is located above the conveyor belt. A transmission mechanism for driving the conveyor belt is installed on the machine base. The transmission mechanism includes a motor, a first gear, a second gear meshing with the first gear, and a grooved wheel mechanism. The output end of the motor is keyed to the first gear, the second gear is driven by a connector to the grooved wheel mechanism, and the grooved wheel mechanism is keyed to the rotating shaft of the conveyor belt. Rotation of the motor's output end drives the first gear to rotate, which in turn drives the second gear to rotate, which in turn drives the grooved wheel mechanism to rotate, causing the conveyor belt to rotate intermittently. This invention eliminates the need for manual operation, reducing labor intensity and improving detection efficiency. Furthermore, the coordinated operation of each component, driven by the same motor, enhances overall coordination. The existing technical solutions mentioned above have the following drawbacks: when inspecting the size and appearance of automotive sunroof sealing strips, it is impossible to stably and quickly process the loading of automotive sunroof sealing strips, which causes the automotive sunroof sealing strips to shift during loading, thereby affecting the accuracy of their inspection.

[0010] Preferably, the air cylinder is fixedly installed at the bottom of the testing platform, and the piston and the air cylinder form a sliding structure.

[0011] Preferably, the outer wall of the platform is fixedly connected to a positioning and correction mechanism. The positioning and correction mechanism includes a first slider fixedly installed on one side of the platform and a second slider movably installed on one side of the detection cover. A return spring is fixedly connected to the outer wall of the second slider, a receiving plate is fixedly connected to one side of the second slider, a correction plate is fixedly connected to the outer wall of the receiving plate, and a laser ranging probe is embedded in the inner wall of the correction plate.

Furthermore, the combined effect of the guide plate and the guide groove can improve the stability of the loading platform as it slides along the inspection table. Furthermore, as the movable block continues to move, the transmission roller can rotate along the support frame and simultaneously slide upward along the wedge-shaped support block, causing the movable rod fixedly connected to the bottom of the platform to slide upward along the movable block, which can lift and feed the car sunroof sealing strip placed on the top of the platform, further improving the stability of feeding the car sunroof sealing strip. Furthermore, as the guide plate slides along the guide groove, it can drive the piston fixedly connected to one end of the receiving rod to slide along the air cylinder, which can draw air inward through the adsorption hole, thus facilitating the automatic adsorption and pre-positioning of the car sunroof sealing strip placed on the platform, further improving the stability of feeding the car sunroof sealing strip. By incorporating a platform and a positioning and correction mechanism, as the platform is lifted, the first slider presses against the second slider and slides along it. This causes the receiving plate, which is fixedly connected to one side of the second slider, to slide towards the detection cover, thereby moving the two correction plates towards each other. This facilitates the pressing and correction of the sunroof sealing strip placed on the platform, achieving further positioning and enhancing the stability of feeding the sunroof sealing strip.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-11 The present invention provides a laser inspection device for automotive sunroof sealing strips, including an inspection platform 1.

[0019] Reference Figures 1-7 As shown, the inspection table 1 has a guide groove 2 inside, a wedge-shaped support block 3 is installed on the top of the inspection table 1, an inspection cover 5 is installed on the top of the inspection table 1, a laser inspection probe 6 is installed on the inner wall of the inspection cover 5, and a positioning and feeding mechanism 4 is installed on the outer wall of the inspection table 1. The positioning and feeding mechanism 4 includes a drive motor 41 fixedly installed on the outer wall of the inspection table 1. The output shaft of the drive motor 41 is fixedly connected to a threaded rod 42 through a coupling. A movable block 43 is movably connected to the outer wall of the threaded rod 42. A threaded groove 44 is opened inside the movable block 43. A guide plate 45 is fixedly connected to the bottom of the movable block 43. An clearance groove 46 is opened inside the movable block 43. A movable rod 47 is movably connected inside the movable block 43. A platform 48 is fixedly connected to the top of the movable rod 47. A support frame 481 is fixedly connected to one side of the platform 48. A rotating shaft 482 is movably connected inside the support frame 481. The outer wall of the rotating shaft 482... A transmission roller 483 is fixedly connected. A counterweight 49 is fixedly connected to the bottom of the platform 48. A threaded rod 42 is threadedly connected to a movable block 43 through a threaded groove 44. A guide plate 45 forms a sliding structure with the detection table 1 through a guide groove 2. The guide plate 45 is symmetrically arranged around the central axis of the movable block 43. Both the guide plate 45 and the guide groove 2 are T-shaped. The transmission roller 483 forms a rotating structure with the support frame 481 through a rotating shaft 482. The transmission roller 483 forms a sliding structure with the wedge-shaped support block 3. The counterweight 49 is engaged with the movable block 43 through a clearance groove 46. A movable rod 47 forms a sliding structure with the movable block 43. A bidirectional lead screw 9 is movably connected to the top of the platform 48. A knob 10 is fixedly connected to the outer wall of the bidirectional lead screw 9. A threaded plate 11 is threadedly connected to the outer wall of the bidirectional lead screw 9. A support column 12 is fixedly connected to one side of the threaded plate 11. An inner support plate 13 is fixedly connected to one end of the support column 12.

[0020] By placing the rectangular sunroof sealing strip on the platform 48, turning the knob 10 drives the double-acting screw 9 to rotate. Since the double-acting screw 9 is threadedly connected to the threaded plate 11, the threaded plate 11 can be moved, causing the inner support plate 13, which is fixedly connected to one end of the receiving column 12, to move. This allows the inner support plate 13 to support the inner wall of the rectangular sunroof sealing strip and prevent it from bending. Starting the drive motor 41 causes the threaded rod 42 to rotate. Since the threaded rod 42 is threadedly connected to the movable block 43 through the threaded groove 44, the movable block 43 can slide along the testing table 1, causing the guide plate 45 to slide along the guide groove 2 opened inside the testing table 1. When the transmission roller 483 on one side of the platform 48 contacts and presses against the wedge-shaped support block 3, as the movable block 43 continues to move, under the action of the rotating shaft 482, the transmission roller 483 can rotate along the support frame 481. The drive roller 483 slides upward along the wedge-shaped support block 3, thereby moving the platform 48 upward. This causes the movable rod 47, which is fixedly connected to the bottom of the platform 48, to slide upward along the movable block 43. At this time, the counterweight 49 moves out of the clearance groove 46, which can lift the car sunroof sealing strip placed on the top of the platform 48 for feeding. At this time, the laser detection probe 6 installed on the inner wall of the detection cover 5 is activated to inspect the size and appearance of the car sunroof sealing strip. When the platform 48 is unloaded, the threaded rod 42 rotates in the opposite direction, causing the movable block 43 to slide outward along the detection table 1, causing the drive roller 483 to slide down along the wedge-shaped support block 3. Under the action of the counterweight 49, the platform 48 can be moved downward, causing the counterweight 49 to engage with the clearance groove 46 for docking and engagement. This allows for quick unloading of the car sunroof sealing strip after inspection.

[0021] Reference Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a receiving rod 451 is fixedly connected to the bottom of the guide plate 45, a piston 452 is fixedly connected to one end of the receiving rod 451, an air cylinder 453 is movably connected to the outer wall of the piston 452, a first one-way valve 454 is installed on the outer wall of the air cylinder 453, a second one-way valve 455 is installed at the output end of the air cylinder 453, an air extraction pipe 456 is installed at the output end of the second one-way valve 455, a flexible hose 457 is fixedly connected to one end of the air extraction pipe 456, an adsorption hole 458 is opened inside the platform 48, the output end of the flexible hose 457 is fixedly installed on one side of the platform 48, the adsorption holes 458 are evenly distributed around the central axis of the platform 48, the air cylinder 453 is fixedly installed at the bottom of the detection table 1, and the piston 452 and the air cylinder 453 form a sliding structure.

[0022] As the guide plate 45 slides along the guide groove 2, it can drive the receiving rod 451 to slide along the detection table 1, causing the piston 452, which is fixedly connected to one end of the receiving rod 451, to slide along the air cylinder 453. At this time, the second one-way valve 455 opens and draws air into the air cylinder 453, while the first one-way valve 454 closes. As the second one-way valve 455 opens, the suction pipe 456 draws air inward, and the suction hole 458 draws air inward, so that the car sunroof sealing strip placed on the platform 48 is automatically adsorbed and pre-positioned when conveying and loading. When the platform 48 retracts the material, the second one-way valve 455 closes and the first one-way valve 454 opens, so that the gas in the air cylinder 453 is discharged from the first one-way valve 454.

[0023] Reference Figure 2 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, a positioning and correction mechanism 7 is fixedly connected to the outer wall of the platform 48. The positioning and correction mechanism 7 includes a first slider 71 fixedly installed on one side of the platform 48 and a second slider 72 movably installed on one side of the detection cover 5. A return spring 73 is fixedly connected to the outer wall of the second slider 72. A receiving plate 74 is fixedly connected to one side of the second slider 72. A correction plate 75 is fixedly connected to the outer wall of the receiving plate 74. A laser ranging probe 8 is embedded in the inner wall of the correction plate 75. The first slider 71 and the second slider 72 form a sliding structure. The first slider 71 is symmetrically arranged about the central axis of the platform 48. The detection cover 5 has a slotted design. The detection cover 5 and the receiving plate 74 form a sliding structure.

[0024] As the loading platform 48 is lifted, the first slider 71, which is fixedly connected to the outer wall of the platform 48, moves upward, causing the first slider 71 to press against the second slider 72 and slide along the second slider 72. This causes the second slider 72 to slide along one side of the detection cover 5, causing the return spring 73 to deform due to the compression. This allows the receiving plate 74, which is fixedly connected to one side of the second slider 72, to slide towards each other along the detection cover 5. This causes the two correction plates 75 to press and correct the sunroof sealing strip placed on the platform 48, so that the rectangular sunroof sealing strip is corrected and centered. This allows the laser detection probe 6 to detect and cover the entire sunroof sealing strip. After the two correction plates 75 are centered and corrected, the laser ranging probe 8 embedded in their inner wall can assist in the detection of the dimensions of the rectangular sunroof sealing strip.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
