[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width and slightly different in length according to the size of each roll. During the production process of steel strip, due to production process problems, defects such as cracks and holes will appear on the surface of the steel strip after processing. These surface defects were usually inspected with the naked eye in the past, and it was difficult to find the defects on the surface of the steel strip. For this reason, during the production process of steel strip, detection devices are usually used to detect the steel strip.

[0003] The existing steel strip inspection device usually adopts visual inspection during the inspection process, photographs the surface of the steel strip, and uploads the defects found during the shooting to the control device for inspection.

Moreover, when the existing technology is used for inspection, it is necessary to drive the steel strip to move by means of a conveyor roller. When moving, the squeezing of the conveyor roller can easily cause wear on the surface of the steel strip. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] Embodiment 1

[0037] An automatic detection device for steel strips, such as Figures 1 to 8As shown, it includes a detection platform 1, a sealing box 2 is installed on the top of the detection platform 1, two groups of steel belt brackets 3 are installed on both sides of the sealing box 2, a steel belt 8 is installed between the steel belt brackets 3, and the steel belt 8 passes through the sealing box 2. Two groups of guide rails 4 are installed inside the sealing box 2, and the top of the guide rail 4 is connected to a connecting frame 401, which is fixed to the top of the sealing box 2. The bottom end of the guide rail 4 is connected to a guide tooth 402. The inside of the sealing box 2 is located between the two groups of guide rails 4. A second cylinder 6 is installed between the two groups of guide rails 4, and the output end of the second cylinder 6 is downwardly connected to a second limiting frame 601, and the first limiting frame 506 is connected to the first limiting frame 506. Two groups of limit rollers are installed up and down inside the second limit frames 601, and the steel belt 8 is located between the two groups of limit rollers. A mounting plate 602 is symmetrically installed on the outer side of the output of the second cylinder 6, and detection cameras 603 are installed at both ends of the mounting plate 602. During detection, the second cylinder 6 is started, and the output end of the second cylinder 6 drives the second limit frame 601 and the mounting plate 602 to rise synchronously, while the positions of the two groups of first limit frames 506 do not move, thereby pulling the steel belt 8 from the middle and stretching the steel belt 8 in the vertical direction. At this time, the detection camera 603 moves upward synchronously to detect the stretched steel belt 8.

[0038] The outer side of each set of guide rails 4 is sleeved with a rotating frame 5, and an adjustment motor 501 is installed on the side of the rotating frame 5. The output end of the adjustment motor 501 is connected to a gear 502, and the gear 502 is located below the guide rail 4 and meshes with the guide gear 402. The top of the rotating frame 5 is connected to a limiting wheel 503, and the top of the guide rail 4 is located on the side of the limiting wheel 503 and a groove is provided. The limiting wheel 503 is engaged in the groove, and the rotating frame 5 rotates along the guide rail 4. The side of the rotating frame 5 is connected to a hanging frame 504, and the bottom end of the hanging frame 504 is installed with a first cylinder 505. The first limiting frame 506 is fixed to the output end of the first cylinder 505. The whole motor 501 drives the gear 502 to rotate, and the gear 502 engages with the guide tooth 402 under the guide rail 4, thereby driving the rotating frame 5 to rotate as a whole. The rotating frame 5 drives the first cylinder 505 to rotate through the lifting frame 504, thereby driving the first limit frame 506 to rotate, thereby changing the angle of the first limit frame 506, twisting the steel belt 8, and stretching the side of the steel belt 8. The rotating frames 5 located on both sides of the second cylinder 6 adjust their angles in opposite directions, so that both sides of the steel belt 8 can be twisted and stretched. At the same time, the twisted and stretched steel belt 8 is further detected by the detection camera 603.

[0039] Please refer to the figure, two groups of electromagnetic cylinders 301 are installed at the bottom end of the steel belt bracket 3, the output end of the electromagnetic cylinder 301 is fixed to the edge of the steel belt bracket 3, and a support frame 302 is connected between the two groups of electromagnetic cylinders 301, which can conveniently support and limit the steel belt roll and support steel belt rolls of different diameters.

[0040] Embodiment 2

[0041] See also Figure 3 and Figure 4 A cleaning roller 508 is connected to the side of a group of first limiting frames 506, and a transmission belt 507 is connected to the end of the limiting roller inside the first limiting frame 506. The transmission belt 507 is in transmission connection with the cleaning roller 508. The cleaning roller 508 rotates to clean the surface of the steel belt 8. A collecting box 201 is installed inside the sealing box 2 below the cleaning roller 508, so as to facilitate the cleaning of the surface of the steel belt 8 and prevent impurities from interfering with subsequent detection. The impurities are collected by the collecting box.

[0042] Embodiment 3

[0043] See also Figure 2 and Figure 7 Both sides of the sealing box 2 are provided with grooves matching the steel belt 8, and the inside of the sealing box 2 is provided with stabilizing frames 7 on the sides of the grooves, and each set of stabilizing frames 7 is connected to a limiting roller to limit the steel belt 8, and a set of stabilizing frames 7 are provided with a cross frame 703 at the top and bottom ends, and a third cylinder 704 is provided on the side of the cross frame 703, and the output end of the third cylinder 704 is connected to a fixed frame 702, and a movable frame 701 is provided below the fixed frame 702, and an extrusion roller is provided inside the movable frame 701 to level the steel belt 8.

[0044] During use of the present invention, it is first necessary to place the steel belt roll into a group of steel belt supports 3, and then pull the steel belt 8 into the sealing box 2, so that the steel belt 8 passes through each group of stabilizing frames 7, the first limiting frame 506, and the second limiting frame 601 to reach the other side of the sealing box 2, until it is connected with another group of steel belt supports 3 to achieve the installation of the steel belt 8. Subsequently, it is necessary to detect the steel belt 8. At this time, the steel belt support 3 without the steel belt roll is connected to the external driving structure (motor, etc.), so as to pull the steel belt 8 out of the steel belt roll and pass through the sealing box 2 for winding. When the steel belt 8 enters the sealing box 2, it will first pass through a group of stabilizing frames 7, and the stabilizing frames 7 stabilize the steel belt 8 to prevent the steel belt 8 from deflecting during the movement. While the steel belt 8 is moving, the detection camera 603 is started to detect the surface of the steel belt 8;

[0045] If the angle of the steel belt 8 needs to be adjusted, the second cylinder 6 is first started, and the output end of the second cylinder 6 drives the second limit frame 601 and the mounting plate 602 to rise synchronously, while the positions of the two sets of first limit frames 506 do not move, so that the steel belt 8 is pulled up from the middle and stretched in the vertical direction. At this time, the detection camera 603 moves upward synchronously to detect the stretched steel belt 8;

[0046] Then, the adjustment motor 501 in the rotating frame 5 is started, and the adjustment motor 501 drives the gear 502 to rotate, and the gear 502 meshes with the guide tooth 402 under the guide rail 4, thereby driving the rotating frame 5 to rotate as a whole, and the rotating frame 5 drives the first cylinder 505 to rotate through the hanging frame 504, thereby driving the first limit frame 506 to rotate, thereby changing the angle of the first limit frame 506, twisting the steel belt 8, and stretching the side of the steel belt 8, and the rotating frames 5 located on both sides of the second cylinder 6 are adjusted in opposite directions, so that both sides of the steel belt 8 can be twisted and stretched, and at the same time, the twisted and stretched steel belt 8 is further inspected by the detection camera 603. If the steel belt 8 has hidden defects at this time, especially the edge of the steel belt 8, the defects will be enlarged under the action of twisting and stretching, so that cracks will appear on the edge of the steel belt 8, which is convenient for the detection camera 603 to detect, thereby improving the detection effect and detection efficiency;

[0047] Moreover, when the steel belt 8 moves in the first limit frame 506, it will drive the internal limit roller to rotate, and the limit roller will drive the cleaning roller 508 to rotate through the transmission belt 507. The cleaning roller 508 rotates to clean the surface of the steel belt 8, and the steel belt 8 is twisted under the action of the first limit frame 506, so that the cleaned impurities will slide down under the action of gravity and enter the collection box 201, which is convenient for cleaning the surface of the steel belt 8 and removing the cleaned impurities from the surface of the steel belt 8, which is convenient for subsequent detection and reduces the accumulation of impurities on the steel belt 8.
