Before the construction of construction engineering, it is necessary to conduct visual inspection on the steel plates and other materials used in the construction engineering to ensure that there are no defects such as cracks, delamination, rust, scratches, etc. on their surfaces, as well as the appearance quality and dimensional deviations of the welds.

[0003] However, most steel plate appearance inspections are currently conducted manually using inspection tools. This method results in low accuracy of the parameters obtained during the inspection process, as well as problems such as large workload and low efficiency. Utility Model Content

[0006] Both sides of the lower side of the frame are provided with bidirectional lead screw modules, and both sides of the upper side of the frame are provided with limit frames. Limit rollers are evenly arranged inside the limit frames. Both sides of the limit frames are connected to movable frames. The lower side of the movable frames is slidably connected to one side of the bidirectional lead screw modules. A pushing component is provided on the upper side of the frame. Both sides of the upper side of the first assembly frame are provided with first electric push rods.

[0009] In the above scheme, reinforcing ribs are provided at the inner bending points of the mobile frame.

[0010] In the above scheme: guide rods are connected to both sides of the push plate, and one side of the guide rod is inserted into the fixed base.

[0011] Beneficial effects

[0012] This utility model provides a pattern acquisition device based on visual recognition, which has the following beneficial effects: 1. This device adopts a pattern acquisition method based on visual recognition. By setting industrial cameras on the lower side of the lifting seat of the frame and the lower side of the second assembly frame, it can accurately acquire pattern information on the surface of the steel plate. Compared with traditional manual inspection, it avoids the detection error caused by human factors and greatly improves the accuracy of the detection parameters, providing reliable data support for the quality inspection of construction projects.

[0013] 2. Through the combination of conveying rollers, bidirectional lead screw modules, limiting frames, limiting rollers, and pushing components, steel plates can be smoothly conveyed on the frame without the need for frequent manual handling of steel plates for inspection. The bidirectional lead screw module, in conjunction with the moving frame, can drive the limiting frame to move and limit steel plates of different widths, keeping them stable during conveying. This facilitates accurate image acquisition by the industrial camera and improves the inspection effect. Attached Figure Description

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example

[0020] Please see Figs. 1-3A pattern acquisition device based on visual recognition includes a frame 1, with assembly plates 2 on both sides of the frame 1. A first assembly frame 3 and a second assembly frame 4 are respectively installed on the upper and lower sides of the assembly plate 2. A first rectangular opening and a second rectangular opening are respectively opened on the upper side of the frame 1. A row of conveying rollers 5 are rotatably connected inside the first rectangular opening and the second rectangular opening.

[0021] Both sides of the lower side of the frame 1 are provided with bidirectional lead screw modules 6, both sides of the upper side of the frame 1 are provided with limit frames 7, the inner side of the limit frames 7 is evenly provided with limit rollers 8, both sides of the limit frames 7 are connected to movable frames 9, the lower side of the movable frames 9 is slidably connected to one side of the bidirectional lead screw module 6, the upper side of the frame 1 is provided with a push assembly, both sides of the upper side of the first assembly frame 3 are provided with first electric push rods 10, the output end of the first electric push rods 10 passes through the first assembly frame 3 and is connected to a lifting seat 11, the lower side of the lifting seat 11 and the lower side of the second assembly frame 4 are provided with industrial cameras 12.

[0022] The pushing component includes a fixed base 13, a second electric push rod 14 is provided on one side of the fixed base 13, and the output end of the second electric push rod 14 passes through the fixed base 13 and is connected to a push plate 15.

[0023] It should be noted that before construction, the steel plates and other materials used in the construction project need to be visually inspected to ensure that there are no defects such as cracks, delamination, rust, scratches, etc. on their surfaces, as well as the appearance quality and dimensional deviations of the welds. At this time, the steel plate can be placed on the upper side of the frame 1, where multiple sets of conveying rollers 5 inside the second rectangular opening support the steel plate. Then, the bidirectional screw module 6 runs and drives the limiting frame 7 and multiple sets of limiting rollers 8 to move closer to each other through the moving frame 9, thus limiting the position of the steel plate. At the same time, the steel plate is not clamped or held, so it will not affect the movement of the steel plate on the conveying rollers 5, and can prevent the steel plate from shifting its position over a large range during the movement, which would affect the subsequent drawing acquisition and inspection.

[0024] It can also limit the movement of steel plates of different widths to keep them stable during transportation, making it easier for the industrial camera 12 to accurately capture images and improve the detection effect;

[0025] Simultaneously, the second electric push rod 14 operates, which can move the steel plate through the push plate 15. At this time, the industrial cameras 12 located on the upper and lower sides of the third rectangular opening can detect defects such as cracks, delamination, corrosion, and scratches on the upper and lower surfaces of the steel plate, as well as accurately measure parameters such as the appearance quality and dimensional deviation of the weld, thereby achieving the purpose of visual recognition and pattern acquisition. After the inspection is completed, the second electric push rod 14 continues to operate, and the steel plate can be removed through the conveying roller 5 inside the first rectangular opening for subsequent processing. Compared with traditional manual inspection, it avoids the detection errors caused by human factors and greatly improves the accuracy of the detection parameters, providing reliable data support for the quality inspection of construction projects.

[0026] Reinforcing ribs 16 are provided at the inner bends of the movable frame 9 to increase the overall strength of the movable frame 9 and enhance the limiting effect of the steel plate.

[0027] Guide rods 17 are connected to both sides of the push plate 15. One side of the guide rod 17 is inserted into the fixed seat 13 to increase the stability of the push plate. At the same time, the lower edge of the push plate 15 is higher than the upper surface of the conveying roller 5, so that the movement of the push plate 15 and the conveying roller 5 will not cause interference.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
