Description

Technical Field

[0001] This utility model belongs to the field of bare steel coil processing technology, and in particular relates to an auxiliary device for surface inspection of bare steel coils. Background Technology

[0002] Bare steel coils refer to hot-rolled or cold-rolled steel coils that have not undergone surface plating, coating, or other treatments. Their surface quality directly affects the performance and appearance of products processed subsequently. The use of surface inspection auxiliary devices aims to efficiently identify potential defects such as cracks, scratches, iron oxide scale, and dents on the surface of bare steel coils through automated visual inspection and sensor scanning technologies. This ensures product quality meets standards, reduces the influx of defective products into downstream processes, lowers production losses and costs, and improves inspection efficiency and accuracy, replacing the subjectivity and limitations of manual inspection.

[0003] However, existing auxiliary devices are not convenient for positioning bare steel coils during use, which can cause the steel coils to deviate or shake when rotating, making it difficult for the inspection agency to stably capture a complete surface image and reducing the overall inspection efficiency. Utility Model Content

By setting a positioning part, it solves the problem that existing auxiliary devices are not convenient for positioning bare steel coils during use, which can cause the steel coils to easily deviate or shake when rotating, making it difficult for the inspection mechanism to stably capture a complete surface image and reducing the overall inspection efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Cylindrical rods are fixedly connected to both the left and right sides of the support frame. Two support rods are hinged to the two cylindrical rods respectively. A power component is provided on the top inner wall of the support frame. Two connecting rods are located on the left and right sides of the drive plate respectively. The power component includes a bracket fixedly connected to the top inner wall of the support frame. A motor is fixedly connected to the bottom of the bracket. The output shaft of the motor is fixedly connected to a threaded rod through a coupling. The top of the threaded rod passes through the bracket and extends outward. The threaded rod is rotatably connected to the bracket. The top of the threaded rod passes through the drive plate. The drive plate is threadedly connected to the threaded rod. The top of the threaded rod is rotatably connected to the support frame. The threaded rod is located inside the support frame.

[0007] Furthermore, the support includes two support components arranged in a mirror image and mounted on the top of the support frame; and a rotating component mounted on the top of the support frame; wherein the rotating component is located between the two support components.

[0008] Furthermore, the positioning component includes a C-shaped bracket fixedly connected to a support rod. The C-shaped bracket has two grooves, each containing a slider. A roller is rotatably connected between the two sliders. Elastic elements are provided within the two grooves. The two grooves are located at the front and rear sides of the C-shaped bracket, respectively. Each elastic element includes a telescopic rod fixedly connected to one of the two grooves. The left side of each telescopic rod is fixedly connected to one of the two sliders. A spring is fitted onto the outer wall of each telescopic rod. The right side of each spring is fixedly connected to the right inner wall of one of the two grooves, and the left side of each spring is fixedly connected to one of the two sliders.

[0009] Furthermore, the support assembly includes two rectangular supports fixedly connected to the top of the support frame, a fixed rod rotatably connected between the two rectangular supports, and a support roller fixedly connected to the outer wall of the fixed rod; wherein the support roller is located between the two rectangular supports.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a positioning part, starting the motor drives the threaded rod to rotate, causing the drive plate to move down along the slide bar. Through the connecting rod, the support rod is pushed to rotate and approach on the cylindrical rod, thereby driving the roller on the C-shaped bracket to approach the bare steel coil to achieve positioning. The telescopic rod and spring can increase the movement range of the roller. Reversing the rotation can release the positioning, preventing the steel coil from shifting or shaking during inspection, thus stably capturing a complete surface image and improving the overall inspection efficiency.

[0013] 2. By setting up a support unit, start motor two. Motor two drives the rotating roller to rotate through the rotating shaft. The rotating roller drives the bare steel coil to rotate by friction with the bare steel coil, which in turn drives the two support rollers to rotate, so as to realize the detection of the surface of the bare steel coil, ensure that the bare steel coil rotates smoothly and at a uniform speed, and stably detect the surface of the steel coil, reducing the instability of detection caused by unstable rotation.
