Description

Technical Field

[0001] This utility model belongs to the field of strip steel inspection technology, specifically, it relates to a strip steel surface cleanliness inspection device. Background Technology

[0002] During the strip steel production process, surface cleaning is required to remove oil, iron filings, and other contaminants from the strip steel surface. Poor cleaning will result in defects (iron mud spots), while oil on the strip steel surface will affect the atmosphere inside the annealing furnace, causing nodules to form inside the furnace, which will seriously affect the production line and product quality.

[0003] During the production process, every 4-8 hours, the on-site operator uses filter paper to wipe the upper and lower surfaces of the steel plate at the continuous return inlet section (cleaning section outlet) with a force of about 3KG for 3-5 seconds. The operator observes the degree of dirt on the filter paper and adjusts the inlet cleaning process in real time based on the wiping results.

[0004] A document with publication number (CN215833396U) discloses a device for detecting the surface cleanliness of galvanized steel strip. The device includes a main body with a placement groove on its top. A sliding mechanism is installed inside the main body, and a fixing mechanism is installed inside the sliding mechanism. A top plate is fixed to the top of the main body, and an adjustment mechanism is installed inside the top plate. The device rotates a rotating head, which drives a threaded rod to rotate. Through the threaded connection between the threaded rod and the connecting plate, and the limiting effect of the telescopic rod, a lower pressure plate moves downward, fixing the galvanized steel strip and preventing it from moving during testing, thus affecting the testing results. Simultaneously, a sliding slider on the outside of the fixing plate allows adjustment of the positions of the connecting plate and the lower pressure plate, facilitating the fixing of steel strips of different lengths and enhancing practicality. After adjustment, bolts are inserted into the fixing holes to fix the slider.

[0005] The aforementioned device performs testing after the strip steel is fixed. However, in actual use, the strip steel needs to be wound into coils after production. The standalone setting of the aforementioned device is not suitable for assembly line production and cannot intuitively display the surface cleanliness of the strip steel. Testing is required by instruments, and the position of the instruments needs to be changed frequently.

[0006] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please see Figure 1-5 A strip steel surface cleanliness testing device includes a testing component for testing the cleanliness of the strip steel. The testing component includes a frame 1, a testing device 2, a mounting shaft 3, and a dust-adhesive roller 4. The frame 1 is symmetrically arranged, and the testing device 2 and the mounting shaft 3 are both arranged between the frame 1. The end of the testing device 2 is fixedly connected to the corresponding frame 1. The mounting shaft 3 is rotatably connected to the frame 1. The dust-adhesive roller 4 is symmetrically arranged on the mounting shaft 3 and is quickly detachably connected to the mounting shaft 3. The dust-adhesive roller 4 is in close contact with the surface of the strip steel. The strip steel is transported through the internal components of the frame 1. The dust-adhesive roller 4 contacts the surface of the strip steel, wipes away the dust on the surface of the strip steel, and adheres it to the dust-adhesive roller 4, which facilitates a direct display of the cleanliness of the strip steel. The cleanliness is tested in real time by the testing device 2. When no one is observing, the cleanliness is reflected by the data, thereby adjusting the cleanliness of the strip steel. The dust-adhesive roller 4 can be replaced, and direct testing can still be performed during replacement.

[0029] It is worth noting that the frame 1 is installed at the discharge port of the cleaning section in strip steel production. Since the discharge port of this part is a known technology in the cleaning section of strip steel production, it is not described in detail in the figure and text. This part includes: strip steel storage silo, S-roll group, conveyor roller, tension stretching roller group, annealing furnace, zinc immersion tank, heat preservation system, cooling system, traction pull-up roller, and monitoring roller set between the S-roll group and the conveyor roller. The monitoring roller is driven to rotate by the strip steel. One end of the rotating shaft of the monitoring roller is connected to a rotary encoder through a coupling. The rotary encoder is connected to the main unit. The hot-dip galvanized strip steel production system of the present invention can automatically stop the machine in time when strip steel breaks by monitoring the setting of the rollers, which makes it easy for operators to connect the strip steel and quickly resume production, improves production efficiency, greatly reduces labor maintenance costs and avoids production losses; the design of the cooling roller saves production line wiring space and production costs; the strip steel production device of this invention has been fully disclosed in the hot-dip galvanized strip steel production system document with announcement number CN106119756B, and will not be described again here.

[0030] It is worth noting that the detection device 2 includes: determining a first distance from the surface of the object to be detected to the objective lens surface of the microscope; controlling a camera to acquire images of multiple flashing components arranged according to a preset rule, obtaining a preset number of images, the preset number of images including images of any flashing component flashing individually; determining a target flashing component among the multiple flashing components based on the pixel value of each image in the preset number of images; determining a second distance between the horizontal plane of the target flashing component and the objective lens surface; and controlling a focusing motor to focus the objective lens based on the first and second distances, so as to detect dust on the surface of the object to be detected through the focused microscope. This achieves the goal of improving the efficiency and accuracy of surface dust detection. The detection device 2 has been fully disclosed in the focusing method, apparatus, equipment, and storage medium document for surface dust detection equipment with announcement number CN115499582B, and will not be repeated here.

[0031] The mounting shaft 3 is symmetrically equipped with mounting discs 31, each fixedly connected to the mounting shaft 3. Each mounting disc 31 is also symmetrically equipped with mounting blocks 33, each fixedly connected to the mounting disc 31. Each mounting block 33 is rotatably connected with a swing rod 37. Each swing rod 37 has a slidably connected limit rod 38 at its end. Each limit rod 38 is fitted with a second spring 39, the end of which is fixedly connected to the corresponding swing rod 37 and limit rod 38. The two ends of the adhesive roller 4 are rotatably connected with connecting blocks 41. Each connecting block 41 has an arc groove 42, and a snap-fit ​​groove is formed in the middle of each arc groove 42. The end of the limit rod 38 slides within the corresponding arc groove 42 and snaps into the snap-fit ​​groove, thus securing the connecting blocks 4. After aligning with the corresponding position on the mounting block 33, manually pull the corresponding limiting rod 38. The limiting rod 38 moves and compresses the second spring 39. The second spring 39 deforms and applies the deformation force to the limiting rod 38. Manually lift the corresponding limiting rod 38 and rotate the corresponding swing rod 37 to slide the limiting rod 38 into the arc groove 42. Continue to rotate the swing rod 37, which drives the limiting rod 38 to slide in the arc groove 42. When the arc groove 42 slides to the snap-fit ​​groove position, the second spring 39 releases the deformation force and pushes the limiting rod 38 to snap into the snap-fit ​​groove. When it is necessary to replace the corresponding sticky roller 4, manually pull the limiting rod 38 to separate it from the snap-fit ​​groove and slide the limiting rod 38 out of the arc groove 42 to quickly complete the removal. The installation and removal of the sticky roller 4 can be quickly completed by lifting the limiting rod 38.

[0032] Each mounting block 33 is slidably connected to a movable rod 35, each movable rod 35 is fixedly connected to a mounting frame 36, each mounting frame 36 abuts against a connecting block 41, and a first spring 34 is provided between each movable rod 35 and the mounting block 33. The end of each first spring 34 is fixedly connected to the corresponding mounting block 33 and movable rod 35. After the connecting block 41 is aligned with the mounting block 33, the connecting block 41 pushes the mounting frame 36, and the mounting frame 36 pushes the movable rod 35 to compress the first spring 34. The first spring 34 deforms and applies the deformation force to the mounting frame 36. The mounting frame 36 pushes the connecting block 41 downward. During the downward movement of the connecting block 41, the arc groove 42 is restricted by the limiting rod 38. Thus, through the cooperation of the first spring 34 and the mounting frame 36, the installation position of the connecting block 41 and the dust roller 4 is not interrupted after installation, and the connecting block 41 cannot slide arbitrarily, ensuring the stability after installation.

[0033] The mounting plate 31 is equipped with a pin 32 that penetrates the corresponding wall surface of the frame 1 and engages with the mounting plate 31. The mounting plate 31 has a connection position at an angle. When the dust roller 4 is replaced, the pin 32 is separated from the mounting plate 31, the mounting plate 31 is rotated, and the bottom mounting block 33 is turned upwards. This re-locks the pin 32 with the corresponding position on the mounting plate 31, thus enabling a continuous and intuitive display of the cleanliness of the strip steel during the replacement of the dust roller 4.

[0034] The frame 1 is symmetrically equipped with a first transmission shaft 12 and a second transmission shaft 13. Each first transmission shaft 12 and second transmission shaft 13 is rotatably connected to the frame 1. The strip steel body 11 is inserted between the first transmission shaft 12 and the second transmission shaft 13. The dust-adhesive roller 4 abuts against the strip steel body 11. As shown in the figure, the strip steel body 11 is inserted between the first transmission shaft 12 and the second transmission shaft 13. Through symmetrical shearing force, the strip steel body 11 is straightened, which facilitates the detection of the cleanliness of the surface of the strip steel body 11. The dust-adhesive roller 4 presses the strip steel body 11 down slightly, which improves the straightness and the effect of the dust-adhesive roller 4 in collecting dust and impurities on the strip steel body 11.

[0035] Working principle: The strip steel is transported through the internal components of the frame 1. The dust-adhesive roller 4 contacts the surface of the strip steel, wiping away dust and adhering it to the roller 4 for easy and intuitive display of the strip steel's cleanliness. The cleanliness is also monitored in real time by the testing equipment 2. Even without observation, the cleanliness is reflected in the data, allowing for adjustments to the strip steel's cleanliness. The dust-adhesive roller 4 is replaceable, allowing for continued visual inspection during replacement. After aligning the connecting block 41 with the corresponding position on the mounting block 33, the corresponding limit rod 38 is manually pulled. The limit rod 38 moves, compressing the second spring 39, causing the second spring 39 to deform. The deformation force is applied to the limiting rod 38. The corresponding limiting rod 38 is manually pulled and the corresponding swing rod 37 is rotated, causing the limiting rod 38 to slide into the arc groove 42. The swing rod 37 is continuously rotated, causing the limiting rod 38 to slide within the arc groove 42. When the arc groove 42 slides to the locking groove position, the second spring 39 releases the deformation force and pushes the limiting rod 38 to engage with the locking groove. When the corresponding sticky roller 4 needs to be replaced, the limiting rod 38 is manually pulled away from the locking groove, and the limiting rod 38 is slid out of the arc groove 42, quickly completing the removal. The removal of the sticky roller 4 is quickly completed through the lifting action of the limiting rod 38. After the connecting block 41 is aligned with the mounting block 33, the connecting block 41 pushes the mounting bracket 36, which in turn pushes the movable rod 35 to compress the first spring 34. The first spring 34 deforms and applies the deformation force to the mounting bracket 36. The mounting bracket 36 pushes the connecting block 41 downwards. During the downward movement of the connecting block 41, the arc groove 42 is restricted by the limiting rod 38. Thus, through the cooperation of the first spring 34 and the mounting bracket 36, the installation position of the connecting block 41 and the sticky roller 4 is seamless, and the connecting block 41 cannot slide freely, ensuring the stability after installation. During the replacement of the sticky roller 4, the pin 3 is removed. 2. Separate from the mounting plate 31, rotate the mounting plate 31, and after the bottom mounting block 33 faces upward, fix the pin 32 to the corresponding position on the mounting plate 31 again, so that the cleanliness of the strip can be displayed continuously and intuitively during the replacement of the dust roller 4. As shown in the figure, the strip body 11 is inserted between the first transmission shaft 12 and the second transmission shaft 13. The strip body 11 is straightened by symmetrical shearing force, which facilitates the detection of the cleanliness of the surface of the strip body 11. The dust roller 4 presses the strip body 11 slightly downward, which improves the straightness and the effect of the dust roller 4 in collecting dust and impurities on the strip body 11.
