Description

Technical Field

[0001] The utility model relates to the technical field of zinc-aluminum-magnesium coated steel plate surface quality detection, in particular to a zinc-aluminum-magnesium coated steel plate surface quality detection machine. Background Art

[0002] The zinc-aluminum-magnesium coated steel plate was initially developed to better replace some of the applications of stainless steel plates. Although stainless steel plates have excellent corrosion resistance, they are expensive. Other hot-dip galvanized steel plates are not as corrosion-resistant as stainless steel plates, and more importantly, they have poor maintenance capabilities for damaged cross sections or coatings. Zinc-aluminum-magnesium coated steel plates have excellent processing performance under severe conditions (stretching, stamping, bending, painting, welding, etc.), and the coating has high hardness and is damage-resistant. Compared with ordinary galvanized and aluminum-zinc-plated products, zinc-aluminum-magnesium coatings have less adhesion, but can better protect steel and achieve better corrosion resistance. Due to this super corrosion resistance, it can replace stainless steel products in some fields. The corrosion-resistant healing property of the cut end face is a major feature of the product. The product is mainly used in civil construction (keel ceiling, porous plate, cable tray), agriculture and animal husbandry (agricultural breeding greenhouse steel structure, steel structure accessories, greenhouse, breeding equipment), railways and roads, power communications (power transmission and distribution high and low voltage switchgear, box-type substation exterior), automotive motors, industrial refrigeration (cooling towers, large outdoor industrial air conditioners) and other industries, with a very wide range of uses.

[0003] During production, due to production processes, production environments, and production equipment, scratches, cracks, and other defects may appear on the surface of steel plates. These defects not only affect the appearance of the steel plates, but also limit the large-scale application of steel plates. In severe cases, they may be downgraded to defective products, resulting in damage to the economic benefits of steel plate manufacturers. Surface defects are a key factor affecting the quality of finished steel plates. As users have higher and higher demands on the surface quality of steel products, companies are paying more and more attention to the surface quality of steel plates. In recent years, the method of defect detection has gradually transitioned from manual detection to visual online detection to improve the ability to monitor surface quality.

[0004] Surface defect detection is achieved by integrating machine vision technologies such as cameras and image processing algorithms to detect the common surface quality of steel plates in real time. For example, the Chinese patent document with publication number CN219179245U discloses "A Steel Plate Surface Defect Detection Device". This device can perform quality inspection on the upper and lower surfaces of steel plates through the visual camera inside the device. However, during the production process of zinc-aluminum-magnesium coated steel plates, due to the production process, production environment and production equipment, a certain amount of dust or granular metal scraps of varying sizes will adhere to the surface of the zinc-aluminum-magnesium coated steel plates. After these dust or scraps adhere to the surface of the zinc-aluminum-magnesium coated steel plates and enter the device for inspection, the device will mistakenly determine that there are small protrusions on the surface of the steel plate, affecting the detection accuracy.

[0030] like Figure 1-5 As shown, a zinc-aluminum-magnesium coated steel plate surface quality detection machine includes a detection box 1, a cleaning device, a limiting device and a detection device.

[0031] The cleaning device includes a mounting plate 2, a transverse pipe 3, a dust suction nozzle 4, a three-way pipe 5, a dust suction pump 6 and an output pipe 7. Two mounting plates 2 are mounted inside the detection box 1, two transverse pipes 3 are respectively arranged on the sides of the two mounting plates 2, two groups of dust suction nozzles 4 are respectively arranged on the two transverse pipes 3, the dust suction pump 6 is mounted on the upper surface of the detection box 1, the three-way pipe 5 is mounted on the input end of the dust suction pump 6, the other two ends of the three-way pipe 5 are respectively connected to the two transverse pipes 3, and the output pipe 7 is mounted on the output end of the dust suction pump 6.

[0032] The limiting device includes a bidirectional screw 9, a synchronous wheel 10, a synchronous belt 11, a threaded seat 12, a limiting plate 13 and a knob 20. The inlet 14 is opened on the front surface of the detection box 1, and the outlet 15 is opened on the rear surface of the detection box 1 and is at the same height as the inlet 14.

[0033] Two round rollers 16 are respectively arranged on one side of the inlet 14 and the outlet 15, two groups of square plates 8 are respectively arranged on the front surface and the rear surface of the detection box 1 and are above the inlet 14, two bidirectional screws 9 are respectively rotatably connected between each group of two square plates 8, two synchronous wheels 10 are respectively installed on the ends of the two bidirectional screws 9 passing through the square plates 8, synchronous belts 11 are arranged on the two synchronous wheels 10, two groups of threaded seats 12 are respectively arranged on the two bidirectional screws 9, two limit plates 13 are respectively installed on the lower surfaces of the two threaded seats 12 on the same thread, and a knob 20 is installed on the other end of one of the bidirectional screws 9 passing through the square plate 8.

[0034] The detection device includes a strip plate 17, a visual camera 18, and a lighting lamp 19. Two strip plates 17 are respectively arranged inside the detection box 1, two sets of visual cameras 18 (using commercially available MV CS200 10GM) are respectively arranged on the sides of the two strip plates 17, and two lighting lamps 19 are arranged on the inner wall of the detection box 1 and on both sides of the outlet 15.

[0035] The rotating knob 20 drives the bidirectional screw 9 connected to it to rotate, and then drives another bidirectional screw 9 to rotate in the same direction through the synchronous wheel 10 and the synchronous belt 11. Each rotating bidirectional screw 9 drives the two threaded seats 12 thereon to approach each other, thereby driving the two limit plates 13 to approach each other until the distance between the two limit plates 13 is the same as the width of the zinc-aluminum-magnesium coated steel plate to be tested.

[0038] The utility model is provided with a limiting device, which can be used to limit the advancing zinc-aluminum-magnesium coated steel plate when it passes through the inside of the device, so that it is always in the central position, thereby preventing the zinc-aluminum-magnesium coated steel plate from being out of position when it moves forward and affecting subsequent detection. At the same time, the distance between the two limiting plates can be adjusted, so that the device can adapt to zinc-aluminum-magnesium coated steel plates of various widths.
