Description

Technical Field

[0001] The utility model belongs to the technical field of zinc coil detection, and in particular relates to a device for detecting defects of finished galvanized coils. Background Art

[0002] Galvanized coils are currently manufactured by immersing thin steel sheets in a bath of molten zinc, forming a zinc coating on the surface. This coating effectively protects the steel from rust and corrosion. To ensure the quality of galvanized coils, laser inspection is often used during production, particularly for quality control and surface defect detection.

[0003] Chinese patent application number CN202222019988.9 discloses a device for detecting bulge defects in cold-rolled galvanized steel coils, including a bracket, a saddle, a detector, and a track. Four support rods and a top plate form a table-like structure. The saddle is placed in the middle of the support rods. The detector is a laser detection device, which is assembled on the track. The track is a groove-type structure slide inside, and the slider is assembled in the slide.

[0004] The above solution uses a detector to realize automatic detection of bulge defects of cold-rolled galvanized products, and provides the secondary system with the unevenness information of the outer side of the steel coil, so that technicians can query the curve information and evaluate the degree of bulge of the steel coil through the secondary system, and analyze the bulge defects of the steel coil through the accumulated data. However, in actual use, a certain amount of dust is often generated during mechanical operations such as cutting, packaging, and transportation. Therefore, there is generally a certain amount of dust in the detected air. The detection probe is continuously exposed to the dust environment, which will cause dust pollutants to gradually adhere to the surface of the probe. The laser probe usually contains lenses and optical elements. These components are very sensitive to dust and pollutants, which will affect the accuracy of its detection. Therefore, frequent manual cleaning is usually required, which not only wastes manpower and time, but also disassembly and reinstallation of parts may accelerate equipment wear.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0031] See also Figure 1-4 As shown, in this embodiment, a galvanized coil finished product defect detection device is provided, which includes a detection frame 1 and a display tray 2. The display tray 2 is located inside the detection frame 1. The galvanized coil body 3 is provided on the upper side of the display tray 2. The lower side of the detection frame 1 is fixedly connected to an empty slot plate 4. The inner wall of the empty slot plate 4 is slidably engaged with a slider 5.

[0032] A detection assembly 6 is installed on the lower side of the slider 5. A dustproof frame 7 located on the outside of the empty slot plate 4 is fixedly connected to the lower side of the detection frame 1. An opening and closing opening 8 is provided on one side of the inner wall of the dustproof frame 7. A sealing plate 9 is rotatably fitted on the inner wall of the opening and closing opening 8. A reset groove 10 is fixedly provided on one side of the opening and closing opening 8. Two tension springs 11 fixedly connected to the sealing plate 9 are fixedly connected to one side of the inner wall of the reset groove 10. A soft rubber strip 12 that matches the opening and closing opening 8 is fixedly connected to one side of the sealing plate 9.

[0033] A dehumidification component 13 is installed on one side of the dustproof frame 7 , and a driving component 14 is installed inside the empty slot plate 4 .

[0034] One aspect of the present embodiment is as follows: when in use, the galvanized coil body 3 is first transported to the upper side of the display tray 2 by the corresponding equipment. After it stabilizes, the stepper motor 142 is started to drive the threaded rod 141 to rotate, and the slider 5 is dragged to drive the detection component 6 to move. During the movement, the corresponding galvanized coil body 3 is illuminated by the laser probe 602 to form an image, which is then compared and processed by the corresponding system. This is a prior art and will not be described in detail.

[0035] After the detection is completed, the slider 5 is reset by reversing the stepper motor 142. During the reset process, its laser probe 602 will squeeze the sealing plate 9, so that the sealing plate 9 opens the opening and closing mouth 8. When the detection component 6 moves to a certain distance inside the dustproof frame 7, it is separated from the sealing plate 9, and then the sealing plate 9 is straightened by the action of the tension spring 11, so that the sealing plate 9 is reset. During the reset process, the soft rubber strip 12 is squeezed and fits between the opening and closing mouth 8, thereby sealing the dustproof frame 7. Then, when not in detection, the detection component 6 can be sealed by the dustproof frame 7, reducing the possibility of contact with dust during non-use, reducing the adsorption of dust on the detection component 6, and shortening its maintenance cycle.
