Description

Technical Field

[0001] This utility model relates to the technical field of steel quality testing equipment, and more specifically, to a low-magnification inspection and photography frame for steel billets. Background Technology

[0002] Currently, the steel industry's low-magnification testing methods for steel billets mostly involve manual on-site photography of multiple segments, followed by individual image analysis by experienced engineers. A comprehensive score is then assigned, and a report is generated. However, manual on-site photography is affected by various factors such as workpiece size, camera, environment, lighting, and personnel, resulting in inconsistent image quality and varying levels of workpiece surface precision. Furthermore, differences in experience among testing and analysis personnel can lead to differing interpretations of the same image. When a non-conforming sample is found, multiple testing and analysis personnel are required to conduct on-site analysis and verification, making it difficult to establish a standardized quality inspection method. Therefore, each steel production enterprise has its own low-magnification testing and rating method, but the quality of the low-magnification images still affects the rating, especially since manual hand-held photography is subject to issues such as camera shake.

[0027] The present invention will be further described below with reference to specific embodiments.

[0028] A low-magnification inspection photographing stand for steel billets includes a base platform 1, a lifting and adjusting device 2, a mobile phone holder 3, a ring light 4, and a resistance adjustment switch 5. The base platform 1 is horizontally positioned for placing steel billet samples. The lifting and adjusting device 2 is vertically fixedly connected to the upper surface of the base platform 1. The mobile phone holder 3 is fixedly installed on the top of the lifting and adjusting device 2 for securing the photographing equipment. The ring light 4 is arranged around the outer periphery of the mobile phone holder 3. The resistance adjustment switch 5 is electrically connected to the ring light 4 for adjusting the light intensity.

[0029] The base platform 1 is made of welded steel plate with a laser-etched cross-grid anti-slip pattern on the surface. The lifting adjustment device 2 is vertically fixed to the center of the base with bolts, and a top plate 24 is welded to its top for mounting the mobile phone holder 3. The ring light 4 is coaxially sleeved around the mobile phone holder 3 with a snap-fit. The knob base 51 of the resistance adjustment switch 5 is fixed to the right-side protrusion 11 of the base. The overall structure forms a rigid support system to eliminate equipment vibration. The ring light 4 is coaxially arranged with the shooting equipment to achieve shadowless lighting, and its height can be adjusted by the lifting adjustment device 2.

[0030] As a preferred embodiment, the lifting adjustment device 2 adopts a telescopic support structure, including:

[0031] The outer sleeve 21 is vertically fixed to the center of the base platform 1 by welding or bolting at its bottom end.

[0032] The inner sleeve 22 is nested inside the outer sleeve 21, and the two are connected by an axial sliding fit structure.

[0033] The locking knob 23 passes through the side wall of the outer sleeve 21 and abuts against the inner sleeve 22, and is radially locked by being screwed in.

[0034] The top plate 24 is fixed to the top of the inner sleeve 22, and the mobile phone holder 3 is installed on the upper surface of the top plate 24 by bolts.

[0035] The outer sleeve 21 is welded to the base, and the inner sleeve 22 is nested within it. The two are engaged by an axial sliding groove. The locking knob 23 passes through the threaded hole on the side wall of the outer sleeve 21. When screwed in, it presses against the inner sleeve 22 to achieve height locking. The mechanical locking structure ensures no displacement after lifting and lowering, avoiding unexpected changes in shooting height.

[0036] As a preferred embodiment, the mobile phone holder 3 includes an adjustable clamping arm 6, the clamping arm 6 comprising:

[0037] The U-shaped fixing seat 61 is rotatably connected to the top plate 24 of the lifting and adjusting device 2 via a rotating shaft at its bottom;

[0038] Double movable clamping arms 62 are symmetrically distributed on both sides of the U-shaped fixed base 61, and each clamping arm 62 has an inwardly curved anti-slip claw 63 at its end;

[0039] A bidirectional threaded rod 64 horizontally passes through a U-shaped fixed seat 61, and both ends engage with the movable clamping arms 62 on both sides through reverse threads. Rotating the threaded rod 64 drives the clamping arms 62 to open and close synchronously.

[0040] During operation, rotating the threaded rod 64 opens the clamping arm 6, and after inserting the mobile phone, rotating it in the opposite direction locks it in place.

[0041] As a preferred embodiment, the ring-shaped supplementary light 4 includes an LED bead array, the LED bead array being integrated into...

[0042] The ring-shaped lampshade 41 is coaxially sleeved on the outer periphery of the U-shaped fixing base 61 of the mobile phone holder 3, and the two are detachably connected by a snap-fit ​​structure.

[0043] The LED mounting plate 42 is embedded in the inner side of the lamp cover in a ring shape, and the LED beads are evenly arranged on the surface of the mounting plate 42 along the circumferential direction.

[0044] It can provide uniform 360° lighting to eliminate shadows. The embedded design can prevent light from shining directly into the lens and causing light spots. The fill light 4 is installed as a whole with the ring lamp cover 41 and can be automatically lit after being powered on.

[0045] As a preferred embodiment, the resistance adjustment switch 5 includes:

[0046] The knob base 51 is fixed to the boss 11 on the side wall of the base platform 1;

[0047] The rotating shaft 52 vertically passes through the knob base 51, with the top end connected to the external knob 53 and the bottom end connected to the internal rheostat.

[0048] Integrated circuit design avoids interference from exposed wiring; rotating the knob clockwise increases illumination, while rotating it counterclockwise decreases it.

[0052] The indicator slider 74 is fitted onto the outer wall of the inner sleeve 22, and has a triangular mark on the side pointing to the scale line.

[0053] Mechanical linkage enables highly digital reading, ensuring accurate and consistent height across multiple batches of images. The scale value indicated by the slider 74 can be observed during lifting and lowering.

[0054] The complete operating procedure for this device is as follows:

[0055] 1. Equipment commissioning phase:

[0056] Rotate the bidirectional threaded rod 64 to open the clamping arm 6, insert the mobile phone and lock it in;

[0057] Pull out the inner sleeve 22 to the specified height on the scale, and tighten the locking knob 23;

[0058] 2. Light control stage:

[0059] Turn on the ring light 4 and rotate the resistance adjustment knob to adjust to a suitable brightness;

[0060] 3. Filming stage:

[0061] Preview the image using your phone's camera to confirm there are no shadows or glare.

[0062] Trigger the shooting to obtain standardized low-magnification inspection images;

[0063] 4. Batch switching phase:
