[0021] The automatic marking mechanism for online detection of aluminum plate surface quality disclosed in this utility model is mainly applied in aluminum plate production scenarios.

[0022] Reference Figures 1 to 5An automatic marking mechanism for online inspection of aluminum plate surface quality includes: an inspection table 1, a mounting frame 2 fixedly connected to the top of the inspection table 1, a mounting plate 3 provided on one side of the mounting frame 2, a high-speed line scan camera 4 provided at the bottom of the mounting plate 3, a lifting component provided inside the mounting frame 2, a laser marking machine 5 provided on one side of the mounting plate 3, a displacement component provided on the top of the mounting plate 3, a display screen 6 provided on the top of the inspection table 1, a control switch 7 provided on one side of the inspection table 1, and two mounting slots 8 opened inside the inspection table 1, with conveying components provided inside the two mounting slots 8. The conveying assembly includes a rotating rod 9, which is equidistantly rotatably connected inside the mounting groove 8. A roller 10 is fixedly connected to the outside of the rotating rod 9. A first motor 11 is provided on one side of the detection table 1, and one end of the output shaft of the first motor 11 is fixedly connected to one side of one of the rotating rods 9. A first synchronous pulley 12 is fixedly connected to the outside of the rotating rod 9. A clamping rod 14 is equidistantly connected to one side of the mounting groove 8 of the first synchronous belt 13 on the outside of the first synchronous pulley 12. The bottom and top of the clamping rod 14 abut against the top and bottom of the first synchronous belt 13, respectively. One end of one of the rotating rods 9 is fixedly connected to a second synchronous pulley 15, and a second synchronous belt 16 is provided on the outer side of the second synchronous pulley 15; Mounting blocks 17 are fixedly connected at equal intervals to the top of the testing table 1. Threaded rods 19 are threadedly connected inside the mounting blocks 17. A positioning plate 18 is rotatably connected to one end of the threaded rod 19. The bottom of the positioning plate 18 is slidably connected to the top of the testing table 1.

[0023] In the above technical solution, considering that the existing aluminum plate detection device requires manual operation by the operator when moving the aluminum plate, it is time-consuming, labor-intensive, and has low detection efficiency. Some detection devices are combined with conveyors. However, the combination of conveyors and detection devices makes the structure of the entire system more complex. The maintenance and upkeep of the equipment require professional technicians and involve expensive repair costs. To solve this problem, the specific operation is as follows: By setting a conveyor assembly in the detection table 1, the threaded rod 19 is rotated according to the width of the aluminum plate to adjust the distance between the two sets of positioning plates 18. Then, the aluminum plate to be detected is placed on the first set of rollers 10. The first motor 11 is started, and the first synchronous wheel 12 and the first synchronous belt 13 are used to drive the first set of rollers 10 to rotate. Then, the second synchronous wheel 15 and the second synchronous belt 16 are used to move the aluminum plate on the first set of rollers 10 along the specified trajectory to the second set of rollers 10. During this process, the aluminum plate will pass under the high-speed line scan camera 4. The high-speed line scan camera 4 scans the surface of the aluminum plate. When a defect is detected on the surface of the aluminum plate, the laser marking machine 5 will emit a weak laser beam to irradiate the surface of the aluminum plate to make dots, thereby forming a mark. By setting up the conveying components, the aluminum plate can automatically move along a predetermined trajectory on the inspection table 1 without manual operation, which greatly improves the inspection efficiency. The distance between the positioning plates 18 can be changed by the threaded rod 19, which can be precisely adjusted according to the width of the aluminum plate to ensure that the aluminum plate always stays in the optimal position during the inspection process and improves the inspection accuracy.

[0024] Reference Figures 1 to 5In a preferred embodiment, the lifting assembly includes a first lead screw 20, which is rotatably connected inside the mounting frame 2. A second motor 21 is disposed on the top of the mounting frame 2. The bottom of the output shaft of the second motor 21 is fixedly connected to the top of the first lead screw 20. The outer side of the first lead screw 20 is threadedly connected to the inside of the mounting plate 3. A limit block 27 is fixedly connected to one side of the mounting plate 3, and one side of the limit block 27 is slidably connected to one side of the mounting frame 2. The displacement assembly includes a fixed block 22, which is fixedly connected to the top of the mounting plate 3. A second lead screw 23 is rotatably connected to one side of the fixed block 22. A third motor 24 is disposed on one side of the mounting plate 3. A movable block 25 is threadedly connected to the outer side of the second lead screw 23. One side of the movable block 25 is fixedly connected to one side of the laser marking machine 5. The bottom of the mounting plate 22 is slidably connected to the top of the mounting plate 3; a baffle 26 is fixedly connected to the top of the fixed block 22, and the bottom of the baffle 26 is slidably connected to the top of the movable block 25; a housing 28 is fixedly connected to one side of the inspection table 1; when inspecting aluminum plates of different widths, the lifting assembly can be used to start the second motor 21 to drive the first lead screw 20 to rotate, and the limiting block 27 can be used to restrict the mounting plate 3 to move up and down inside the mounting frame 2, thereby adjusting the height of the high-speed line scan camera 4 to ensure that the high-speed line scan camera 4 can cover the aluminum plate. Then, the displacement assembly can be used to start the third motor 24 to drive the second lead screw 23 to rotate, and the baffle 26 can be used to restrict the movable block 25 to move on the top of the mounting plate 3, thereby driving the laser marking machine 5 to move back and forth, so that the detected defective parts can be marked at any time. The height of the high-speed line scan camera 4 can be adjusted by the lifting assembly to ensure that it can accurately cover the entire surface of the aluminum plate, reduce the detection blind zone, and improve the detection accuracy. The position of the laser marking machine 5 can be adjusted by the displacement assembly to ensure that it can accurately mark the detected defects and avoid marking errors or omissions.

[0025] Working principle: In use, by setting up a conveying assembly in the inspection table 1, firstly, according to the width of the aluminum plate, rotate the threaded rod 19 to adjust the distance between the two sets of positioning plates 18. Start the second motor 21 to drive the first lead screw 20 to rotate, and use the limiting block 27 to restrict the mounting plate 3 to move up and down inside the mounting frame 2, thereby adjusting the height of the high-speed line scan camera 4 to ensure that the high-speed line scan camera 4 can cover the aluminum plate. Then, place the aluminum plate to be inspected on the first set of rollers 10, start the first motor 11, and use the transmission action of the first synchronous pulley 12 and the first synchronous belt 13 to drive the first set of rollers 10 to rotate. The aluminum plate on the first set of rollers 10 is moved along a designated trajectory to the second set of rollers 10 by the transmission action of the second synchronous pulley 15 and the second synchronous belt 16. During this process, the aluminum plate will pass under the high-speed line scan camera 4. The high-speed line scan camera 4 scans the surface of the aluminum plate. When a defect is detected on the surface of the aluminum plate, the third motor 24 is started to drive the second lead screw 23 to rotate. By the restriction of the baffle 26, the movable block 25 moves on the top of the mounting plate 3, thereby driving the laser marking machine 5 to move back and forth to mark the detected defective part.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
