Description

Technical Field

[0001] This utility model relates to the field of steel strip inspection technology, and in particular to a steel strip defect detection device. Background Technology

[0002] Steel strip is a strip product based on carbon steel. High-strength steel wires are incorporated into the steel strip, enabling it to withstand strong tensile forces. It is often used for traction and transportation in conveyors and is also frequently used in the traction structure of elevators. During the production of steel strip, its surface needs to be inspected to prevent defects such as dents and scratches from appearing on the surface after packaging.

[0003] Existing technologies, such as Chinese Patent Publication No. CN221078451U, disclose a steel strip surface inspection device. This device uses a combination of a transmitting and receiving light module to detect the bottom surface of the steel strip by reflecting light; it also uses a photographic module on the upper part of the steel strip to take pictures, achieving image inspection of the upper part of the steel strip. This device achieves simultaneous inspection of the upper and lower surfaces of the steel strip, and the two inspection methods are completely different, ensuring accuracy. This steel strip surface inspection device, through the combined use of the photographic module and the inkjet module, allows operators to first perform a preliminary inspection of the images of problematic areas on the steel strip surface, and then check the specific location of the processed steel strip based on the inkjet marks, thereby further improving accuracy and facilitating correction or cutting operations on the detected problematic areas. However, this utility model does not effectively clean the steel strip surface before inspection, and dust and impurities on it may affect the inspection results.

[0004] To address the issue that steel strip defect detection devices cannot efficiently clean the steel strip surface before inspection, existing technologies use methods such as camera imaging to detect surface defects. However, since the steel strip surface may contain dust, impurities, and other foreign matter, these can easily affect the inspection results, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing steel strip defect detection devices are not convenient for efficiently cleaning the surface of the steel strip before detection, and therefore proposes a steel strip defect detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel strip defect detection device, comprising a frame, guide rollers, a camera, and a cleaning mechanism, wherein the cleaning mechanism is disposed on the surface of the frame; The cleaning mechanism includes a motor, which is fixedly mounted on the surface of the frame. A rotating shaft is fixedly connected to the output end of the motor. A conveying roller is fixedly connected to the surface of the rotating shaft. A half gear is fixedly connected to the surface of the rotating shaft. A guide rod is fixedly connected to the surface of the frame. A toothed plate is slidably connected to the surface of the guide rod. The half gear meshes with the surface of the toothed plate. A spring is sleeved on the surface of the guide rod. One end of the spring is fixedly connected to the surface of the frame, and the other end of the spring is fixedly connected to the surface of the toothed plate. A sliding groove is provided on the surface of the frame. A mounting plate is fixedly connected to the surface of the toothed plate. The mounting plate is slidably connected to the surface of the sliding groove. A cleaning plate is provided on the surface of the mounting plate.

[0007] Furthermore, there are two sets of both the mounting plate and the cleaning plate. The surface of the cleaning plate is provided with a slot. The inner wall of the mounting plate is slidably connected with a retaining plate. The retaining plate is engaged with the surface of the slot. A pull rod is fixedly connected to the surface of the retaining plate. The pull rod is slidably connected to the inner wall of the mounting plate.

[0008] Furthermore, a second spring is sleeved and connected to the surface of the pull rod. One end of the second spring is fixedly connected to the surface of the clamping plate, and the other end of the second spring is fixedly connected to the inner wall of the mounting plate.

[0009] Furthermore, the surface of the card plate is provided with an arc surface, and there are two card slots, two card plates and two pull rods, with the two card slots arranged symmetrically.

[0010] Furthermore, the surface of the frame is provided with an adjustment mechanism, the adjustment mechanism including a limiting groove, the limiting groove being formed on the surface of the frame, a slide table being slidably connected to the surface of the limiting groove, and the camera being fixedly mounted on the surface of the slide table.

[0011] Furthermore, a second motor is fixedly mounted on the surface of the frame, and a bidirectional lead screw is fixedly connected to the output end of the second motor. The slide is threadedly connected to the surface of the bidirectional lead screw.

[0012] Furthermore, there are two sets of the limiting groove, the camera, and the slide, and multiple sets of the guide rollers, all of which are rotatably mounted on the surface of the frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a cleaning mechanism is set up. Starting the motor causes the rotating shaft to drive the conveyor roller and the half-gear to rotate. The conveyor roller, in conjunction with the guide roller, conveys the steel strip. When the half-gear contacts the toothed plate, it drives the toothed plate to slide along the guide rod and press against the spring. When the half-gear disengages from the toothed plate, the toothed plate returns to its original position under the rebound action of the spring. This process repeats, causing the mounting plate to continuously reciprocate along the slide groove. The cleaning plate on it cleans the upper and lower surfaces of the steel strip, allowing for clear imaging to detect defects. When the cleaning plate needs to be replaced, simply pull the two sets of levers to lock it in place. Once the plate disengages from the slot and spring two is pressed, the cleaning plate can be pulled out from the mounting plate. Inserting a new cleaning plate into the mounting plate, the curved surface allows the plate to slide directly into the inner wall of the mounting plate without the need for manual pulling of the lever. After the cleaning plate is inserted, the spring two returns and engages the slot, securing it in place. By incorporating this cleaning mechanism, the reciprocating cleaning plate can clean the upper and lower surfaces of the steel strip before defect detection, preventing impurities from affecting the imaging of the steel strip. Furthermore, the system utilizes only the rotation of the conveyor rollers as a power source, saving costs and effectively improving the equipment's convenience.

[0014] 2. In this utility model, by setting an adjustment mechanism, two sets of cameras are used to photograph the upper and lower surfaces of the steel strip in order to detect surface defects. Starting the second motor causes the bidirectional lead screw to rotate, which can drive the two sets of slides to move towards or away from each other along the limiting groove, so as to adjust the distance between the two sets of cameras. By setting an adjustment mechanism, two sets of adjustable-position cameras are used to photograph the upper and lower surfaces of the steel strip, so as to maintain a suitable shooting distance between the camera and the steel strip according to the on-site environment, which effectively improves the convenience of the equipment.

[0018] The following section will explain the specific setup and function of its cleaning mechanism 4 and adjustment mechanism 5.

[0019] In this embodiment: the cleaning mechanism 4 includes a motor 401, which is fixedly mounted on the surface of the frame 1. The output end of the motor 401 is fixedly connected to a rotating shaft 402. A conveying roller 403 is fixedly connected to the surface of the rotating shaft 402. A half gear 404 is fixedly connected to the surface of the rotating shaft 402. A guide rod 405 is fixedly connected to the surface of the frame 1. A toothed plate 406 is slidably connected to the surface of the guide rod 405. The half gear 404 meshes with the surface of the toothed plate 406. A spring 407 is sleeved on the surface of the guide rod 405. One end of the spring 407 is fixedly connected to the surface of the frame 1, and the other end of the spring 407 is fixedly connected to the surface of the toothed plate 406. A sliding groove 408 is opened on the surface of the frame 1. A mounting plate 409 is fixedly connected to the surface of the toothed plate 406. The mounting plate 409 is slidably connected to the surface of the sliding groove 408. A cleaning plate 410 is provided on the surface of the mounting plate 409.

[0020] The effects achieved by the above components are as follows: The motor 401 and rotating shaft 402 are configured so that when the motor 401 is started and the rotating shaft 402 rotates, it drives the conveyor roller 403 and the half-gear 404 to rotate. The conveyor roller 403 is configured to cooperate with the guide roller 2 to convey the steel belt. The half-gear 404, guide rod 405, toothed plate 406, and spring 407 are configured so that when the half-gear 404 contacts the toothed plate 406, it drives the toothed plate 406 to slide along the guide rod 405 and press against the spring 407. 7. When the half gear 404 disengages from the toothed plate 406, the toothed plate 406 returns to its original position under the rebound action of the spring 407. This process repeats. The sliding groove 408 is provided to facilitate the sliding of the mounting plate 409. The mounting plate 409 is provided to facilitate the loading and unloading of the cleaning plate 410. The cleaning plate 410 is provided so that when the toothed plate 406 reciprocates, it can drive the mounting plate 409 to move along the sliding groove 408, thereby using the reciprocating cleaning plate 410 to efficiently clean the surface of the steel strip.

[0021] Specifically, there are two sets of mounting plates 409 and cleaning plates 410. The surface of the cleaning plate 410 is provided with a slot 411. The inner wall of the mounting plate 409 is slidably connected with a retaining plate 412. The retaining plate 412 is engaged with the surface of the slot 411. The surface of the retaining plate 412 is fixedly connected with a pull rod 413. The pull rod 413 is slidably connected with the inner wall of the mounting plate 409.

[0022] The effects achieved by the above components are as follows: the two sets of cleaning plates 410 are provided to facilitate cleaning of both the upper and lower surfaces of the steel strip; the slots 411 and the plate 412 are provided to fix the cleaning plate 410 on the mounting plate 409 when the plate 412 is inserted into the slot 411; and the pull rod 413 is provided to facilitate pulling the plate 412 to disengage it from the slot 411 so that the cleaning plate 410 can be removed.

[0023] Specifically, a second spring 414 is sleeved and connected to the surface of the pull rod 413. One end of the second spring 414 is fixedly connected to the surface of the clamping plate 412, and the other end of the second spring 414 is fixedly connected to the inner wall of the mounting plate 409.

[0024] The effect achieved by the above components is that the spring 414 is set so that the clamping plate 412 can be clamped in the slot 411, and its rebound effect can be used to facilitate the reset of the clamping plate 412.

[0025] Specifically, the surface of the card plate 412 is provided with an arc surface 415, and there are two card slots 411, two card plates 412 and two pull rods 413, with the two card slots 411 arranged symmetrically.

[0026] The effects achieved by the above components are as follows: the curved surface 415 is designed so that when the cleaning plate 410 is inserted into the mounting plate 409, the clamping plate 412 can be directly pushed into the inner wall of the mounting plate 409 under the action of the curved surface 415, without the need to manually pull the lever 413, so as to achieve quick installation. The two slots 411 and the clamping plate 412 are designed so that the cleaning plate 410 can only be removed when both clamping plates 412 are disengaged from the slots 411, so as to avoid accidental contact.

[0027] Specifically, the surface of the frame 1 is provided with an adjustment mechanism 5, which includes a limiting groove 51. The limiting groove 51 is formed on the surface of the frame 1, and a slide table 52 is slidably connected to the surface of the limiting groove 51. The camera 3 is fixedly installed on the surface of the slide table 52.

[0028] The effects achieved by the above components are as follows: the limiting groove 51 is provided to guide and limit the movement of the slide 52, preventing it from rotating with the bidirectional lead screw 54; the slide 52 is provided to facilitate the placement of the camera 3.

[0029] Specifically, a second motor 53 is fixedly mounted on the surface of the frame 1, and a bidirectional lead screw 54 is fixedly connected to the output end of the second motor 53. The slide table 52 is threadedly connected to the surface of the bidirectional lead screw 54.

[0030] The effect achieved by the above components is as follows: the motor 53 and the bidirectional lead screw 54 are set so that when the motor 53 is started and the bidirectional lead screw 54 is rotated, it can drive the two sets of slides 52 to move towards each other or away from each other along the limiting groove 51, thereby adjusting the distance between the two sets of cameras 3.

[0031] Specifically, there are two sets of limiting grooves 51, cameras 3 and slides 52, and multiple sets of guide rollers 2, all of which are rotatably mounted on the surface of the frame 1.

[0032] The effects achieved by the above components are as follows: setting two sets of cameras 3 is to facilitate simultaneous shooting of the upper and lower surfaces of the steel strip, ensuring good defect detection efficiency; setting guide rollers 2 is to assist in the conveying of the steel strip.

[0033] Working principle: By setting up the cleaning mechanism 4, starting the motor 401 causes the rotating shaft 402 to drive the conveyor roller 403 and the half gear 404 to rotate. The conveyor roller 403, in conjunction with the guide roller 2, conveys the steel strip. When the half gear 404 contacts the toothed plate 406, it drives the toothed plate 406 to slide along the guide rod 405 and press the spring 407. When the half gear 404 disengages from the toothed plate 406, the toothed plate 406 returns to its original position under the rebound action of the spring 407. This process repeats, causing the mounting plate 409 to continuously reciprocate along the slide groove 408. The cleaning plate 410 on it cleans the upper and lower surfaces of the steel strip, so that subsequent clear photography can be taken to detect defects. When the cleaning plate 410 needs to be replaced, simply pull the two sets of pull rods 413. Once the clamping plate 412 disengages from the clamping slot 411 and presses against the second spring 414, the cleaning plate 410 can be pulled out from the mounting plate 409. Inserting the new cleaning plate 410 into the mounting plate 409, under the action of the arc surface 415, the clamping plate 412 can be directly pushed into the inner wall of the mounting plate 409 without manually pulling the lever 413. After the cleaning plate 410 is inserted into place, the clamping plate 412 is engaged in the clamping slot 411 under the rebound action of the second spring 414, achieving fixation. By setting the cleaning mechanism 4, the reciprocating cleaning plate 410 can be used to clean the upper and lower surfaces of the steel strip before defect detection, avoiding impurities and foreign objects affecting the imaging of the steel strip. Furthermore, it only requires the rotation of the conveyor roller 403 as a power source, saving costs and effectively improving the convenience of the equipment.

[0034] Furthermore, by setting an adjustment mechanism 5, two sets of cameras 3 are used to photograph the upper and lower surfaces of the steel strip to detect surface defects. The motor 53 is started to rotate the bidirectional lead screw 54, which can drive the two sets of slides 52 to move towards or away from each other along the limiting groove 51, so as to adjust the distance between the two sets of cameras 3. By setting an adjustment mechanism 5, two sets of adjustable-position cameras 3 are used to photograph the upper and lower surfaces of the steel strip, so as to maintain a suitable shooting distance between the cameras 3 and the steel strip according to the on-site environment, which effectively improves the convenience of the equipment.
