[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] In this article, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0028] Figure 1 This is a schematic diagram of the electrolyte cylinder defect detection device provided in this application embodiment. The mounting frame 2 of the electrolyte cylinder defect detection device 1 is erected on the coil conveyor line. It is generally assumed that the mounting frame on the conveyor line adopts a Z-shaped gantry structure, that is, two side beams and a top crossbeam. An adjustable component 3 that can slide laterally is provided on the top crossbeam of the mounting frame 2. The detection fixing frame 4 is suspended above the coiled steel through the adjustable component 3. The adjustable component 3 can form a sliding relationship with the crossbeam in the form of a slot or a slide rail. This sliding relationship can be controlled by electric or manual control to move the adjustable component 3 left and right (that is, in a direction perpendicular to the direction of movement of the coiled steel).

[0029] The camera module 5 is mounted on the inspection fixture 4 and contains several camera lenses arranged side by side to photograph the coiled steel plate below. Figure 1 The camera module consists of nine cameras arranged side-by-side, each with a specific shooting angle to ensure that the entire width of the steel section can be captured. In other embodiments, the number of cameras can be increased or decreased according to actual needs; this application does not limit this.

[0030] like Figure 2The schematic diagram of the defect detection scenario shown indicates that at least two sets of strip light sources are installed on the mounting frame 2. The lower strip light source 6 is installed on the side beam of the mounting frame 2, while the upper strip light source 7 is installed on the detection fixing frame 4. The two sets of strip light sources are located above and below the coil conveyor line, respectively, and the steel passes between the two strip light sources to ensure that the light illuminates both sides of the coil steel.

[0031] Figure 3 yes Figure 1 In the enlarged view at point A, in one possible implementation, to allow the light source to adapt to steel of different heights, mounting plates 61 can be provided at both ends of the lower strip light source 6. The mounting plates 61 are slidably mounted on the side beams of the mounting frame 2. This sliding connection can be made via a slide rail or a slot, and can be controlled electrically or manually. The height of the lower light source can be adjusted at any time when the production line height changes.

[0032] Figure 4 This is a schematic diagram of another possible form of the electrolyte cylinder defect detection device. To protect the camera, a housing 8 can be installed at the crossbeam position of the mounting bracket 2, such as... Figure 4 The rectangular outer shell 8 can be composed of two half-shells joined together. The adjustment assembly 3, the detection mounting bracket 4, and the camera module 5 are located inside the shell 8, while the lower strip light source 6 is located at the bottom of the shell. The upper strip light source 7 and several camera lenses arranged side-by-side illuminate and detect defects through openings at the bottom of the shell 8.

[0033] Figure 5 This is a partial schematic diagram of an electrolyte cylinder defect detection device. The detection mounting frame 4 includes two fixing plates 41 on both sides and a camera horizontal plate 42 connecting the two fixing plates 41; the camera module 5 is mounted on the camera horizontal plate 42. The detection mounting frame 4 can be a plate-like structure or a strip-like structure, such as... Figure 5 The detection mounting bracket 4 has a U-shaped structure with a protruding mounting handle at the top, through which the camera horizontal plate 42 is mounted and fixed. In some other structures, the camera horizontal plate 42 can be mounted on a U-shaped side leg, thus making the camera equivalent to being at the same height as the upper strip light source 7.

[0034] In some embodiments, at least two sets of upper strip light sources 7 may be provided on the light source mounting bracket 9, with the camera module 5 located between the two sets of upper strip light sources 7, which can ensure the uniformity of light source illumination.

[0035] Light source mounting brackets 9 are provided on the fixing plates 41 on both sides, and the upper strip light source 7 is mounted through the light source mounting brackets 9 on both sides. Figure 5Taking a strip-shaped structure as an example, the strip-shaped light source mounting bracket 9 and the U-shaped detection fixing bracket 4 form a U-shaped structure, with the end of the upper strip light source 7 located above the U-shaped light source mounting bracket 9. Of course, in some embodiments, the upper strip light source 7 can also be suspended below the light source mounting bracket 9.

[0036] In some embodiments, a plurality of mounting holes are horizontally provided on the camera horizontal plate 42, and the camera module 5 is mounted on the camera horizontal plate 42 through the mounting holes. When the camera position is not suitable, the position of the mounting holes can be changed to assist in adjustment.

[0037] Figure 6 yes Figure 5 The enlarged view at point C shows that, considering the fixed position of the bottom, the upper strip light source 7 should have as many adjustable postures as possible to adapt to blind hole illumination at various tilt angles. For example, light source adjustment shafts 71 can be set at both ends of the strip light source, and the light source adjustment shafts 71 are fitted into the light source mounting block 72. The light source mounting frame 9 is set parallel to the movement direction of the coiled steel, and the light source mounting block 72 is slidably set on the light source mounting frame 9. In this way, the upper strip light source 7 can rotate within the light source mounting block 72 based on the light source adjustment shafts 71 to adjust the light source angle. This operation can be performed by the worker according to the actual scenario; simply rotating the upper strip light source 7 achieves the purpose.

[0038] Figure 7 yes Figure 5 The enlarged view at point B shows that because the lower bar light source 6 can be raised and lowered, the upper bar light source 7 should also have the function of raising and lowering for illumination. Therefore, in this embodiment, the adjustment component 3 is designed to include an adjustment base plate 31, an adjustment slide plate 32, and an adjustment bolt 33. The adjustment base plate 31 is slidably mounted on the side beam of the mounting frame 2, the adjustment slide plate 32 is slidably mounted on the adjustment base plate 31, and the adjustment bolt 33 is fixedly installed in the camera horizontal plate 42. The adjustment slide plate 32 can be connected to the adjustment base plate 31 via a slide groove or slide rail, and is threadedly connected by the adjustment bolt 33. When raising and lowering control is required, the adjustment slide plate 32 can be raised and lowered using the adjustment bolt 33. The adjustment bolt 33 is fixedly installed in the camera horizontal plate 42.

[0039] During normal operation, the coiled steel passes between the upper and lower strip light sources. The lower light can pass through the blind holes in the steel, allowing the bright spots to be clearly captured from the perspective of the camera above. The upper strip light source shines downwards, providing supplementary lighting as needed to ensure uniform illumination even in dark environments, assisting the camera in capturing images and performing defect detection clearly and efficiently.

[0040] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
