Technical Field
[0001] This utility model relates to the field of steel pipe production technology, and in particular to a positioning device for recognizing the content of spray marks on steel pipes. Background Technology
[0002] In the field of steel pipe manufacturing and quality inspection, accurate identification of markings on the surface of steel pipes is crucial for product traceability, specification confirmation, and quality control. The markings on steel pipes contain key information such as product model, batch number, and specifications. To ensure that the markings can be accurately read by a visual recognition system, the steel pipe needs to be precisely positioned in the optimal working position for the system. Therefore, positioning devices for steel pipe marking identification have emerged, which assist visual recognition systems in obtaining clear and complete images of the markings, thereby improving recognition efficiency and accuracy.
[0003] Existing steel pipe marking content recognition and positioning technologies often employ manual or semi-manual operation methods. For example, the steel pipe is secured by manually adjusting the bolts on the operating table, which moves the clamping plate. This method relies heavily on the operator's experience and skill. The steel pipe is first placed on the operating table, and then the bolts are tightened one by one, causing the clamping plate to slowly move and clamp the pipe, completing the initial positioning. After this initial positioning, a vision recognition system identifies the marking content. During the positioning process, the operator needs to repeatedly confirm the position of the steel pipe and the tightness of the clamping plate to ensure that the marking content is within the field of view of the vision recognition system.
[0004] Since the manual adjustment process is quite complicated, requiring operators to tighten or loosen multiple bolts one by one, it not only consumes a lot of time, but also is prone to adjustment errors under frequent operation, resulting in inaccurate fixing position of the steel pipe, which in turn affects the efficiency of marking content recognition. Therefore, a positioning device for marking content recognition on steel pipe is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a positioning device for recognizing the content of spray markings on steel pipes, aiming to improve the problem that the traditional method of fixing steel pipes by turning bolts to move clamps is cumbersome and affects work efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A positioning device for recognizing the content of spray-painted markings on steel pipes includes an operating table, a fixing frame fixedly connected to the side wall of the operating table, an adjustment component provided on the side wall of the fixing frame, and a fixing component provided inside the operating table.
[0008] The fixing assembly includes a clamping plate. A transverse groove is formed inside the operating table. A sliding plate is fixedly connected inside the operating table. A connecting column is slidably connected to the side wall of the sliding plate. The bottom of the clamping plate is fixedly connected to the side wall of the connecting column. A rubber pad is fixedly connected to the side wall of the clamping plate. A fixing block is fixedly connected to one side wall of the connecting column. A rack is fixedly connected to the side wall of the fixing block. A sliding frame is fixedly connected to the side wall of the sliding plate. A full gear is rotatably connected inside the operating table. The rack meshes with the full gear. A motor is fixedly connected to the bottom of the operating table. The output end of the motor is connected to the full gear.
[0009] As a further description of the above technical solution:
[0010] The adjustment assembly includes a connecting frame, and an industrial camera is mounted on the side wall of the fixing frame. The side wall of the connecting frame is fixedly connected to the bottom of the industrial camera.
[0011] As a further description of the above technical solution:
[0012] The side wall of the fixed frame is provided with a connecting frame, and a rotating shaft is rotatably connected inside the connecting frame. The connecting frame is fixedly connected inside the side wall of the rotating shaft.

[0014] A worm gear is fixedly connected to the side wall of the rotating shaft, and the side wall of the worm gear is rotatably connected inside the connecting frame. A worm is rotatably connected inside the connecting frame, and the worm gear meshes with the worm.
[0015] As a further description of the above technical solution:
[0016] A second motor is fixedly connected to the side wall of the connecting frame, and the output end of the second motor is connected to the worm gear. A fixed frame is fixedly connected to the side wall of the fixing bracket, and a fixed column is rotatably connected inside the fixed frame.
[0017] As a further description of the above technical solution:
[0018] The bottom of the connecting frame is fixedly connected to the side wall of the fixed column, the side wall of the fixed column is fixedly connected to the main gear, and the inside of the fixed frame is rotatably connected to the driven gear, with the main gear meshing with the driven gear.
[0019] As a further description of the above technical solution:
[0020] The side wall of the fixed frame is equipped with a motor three, and the output end of the motor three is connected to the driven gear.
[0021] As a further description of the above technical solution:
[0022] The sidewall of the connecting column is slidably connected inside the transverse groove, and the sidewall of the rack is slidably connected inside the slide frame.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the steel pipe is placed on the operating table, and the motor is started. Its output end drives the full gear to rotate. The full gear meshes with the rack, converting the rotational motion into linear motion. The rack drives the connecting column to slide in the side wall of the slide plate and the transverse groove through the fixing block, so that the clamping plate moves towards the middle to clamp the steel pipe. The rubber pad increases the friction and completes the fixed positioning. This solves the problem that the traditional method of fixing the steel pipe by turning the bolt to drive the clamping plate is more troublesome and affects the work efficiency. The above technical solution improves the efficiency of fixing the steel pipe.
[0025] 2. In this utility model, when adjusting the position and angle of the industrial camera, motor two is started, and its output end drives the worm gear to rotate. The worm gear meshes with the worm wheel, transmitting the rotational motion to the worm wheel, which drives the rotating shaft to change the angle between the connecting frame and the industrial camera. At the same time, motor three is started, and its output end drives the driven gear to rotate. The driven gear meshes with the main gear, transmitting power to the main gear to drive the fixed column to rotate the connecting frame. This adjusts the horizontal position of the industrial camera and expands the shooting range, facilitating subsequent system analysis and recognition of the sprayed marking image. This solves the problem that industrial cameras are difficult to adapt to changes in the sprayed marking position of steel pipes of different specifications, and the single shooting angle easily leads to incomplete shooting of the sprayed marking content. The above technical solution improves the adaptability of industrial cameras to shooting different steel pipes. Attached Figure Description

The side wall of the rack 9 is slidably connected inside the slide frame 10. The motor 12 works with the full gear 11 and the rack 9 to perform transmission motion. The output end of the motor 12 drives the full gear 11 to rotate. The full gear 11 meshes with the rack 9, converting the rotational motion into the linear motion of the rack 9, which in turn drives the connecting column 5 and the clamping plate 6 to slide in the transverse groove 3, achieving the effect of automatically clamping or releasing the steel pipe and realizing the fixed positioning of the steel pipe.
[0035] Reference Figure 1 , Figure 4 and Figure 5The adjustment assembly includes a connecting frame 14, and an industrial camera 13 is mounted on the side wall of a fixed frame 2. The industrial camera 13 is the core component for marking content recognition, used to capture images of the markings on the surface of the steel pipe and transmit the image information to the subsequent processing system for analysis and recognition. The side wall of the connecting frame 14 is fixedly connected to the bottom of the industrial camera 13. A connecting frame 15 is mounted on the side wall of the fixed frame 2, and a rotating shaft 16 is rotatably connected inside the connecting frame 15. The side wall of the rotating shaft 16 is fixedly connected inside the connecting frame 14. A worm gear 17 is fixedly connected to the side wall, and the worm gear 17 is rotatably connected inside the connecting frame 15. A worm 18 is rotatably connected inside the connecting frame 15. The worm gear 17 meshes with the worm 18. A second motor 19 is fixedly connected to the side wall of the connecting frame 15. The output end of the second motor 19 is connected to the worm 18. The rotating shaft 16 rotates in conjunction with the worm gear 17 and the worm 18. The output end of the second motor 19 drives the worm 18 to rotate, and the worm 18 meshes with the worm gear 17, transmitting the rotational motion of the worm 18 to the worm gear 17. The rotating shaft 16 is driven to rotate, thereby changing the angle between the connecting frame 14 and the industrial camera 13, achieving the effect of adjusting the shooting angle of the industrial camera 13 to adapt to the shooting of the marking content in different positions. A fixed frame 20 is fixedly connected to the side wall of the fixed frame 2, and a fixed column 21 is rotatably connected inside the fixed frame 20. The bottom of the connecting frame 15 is fixedly connected to the side wall of the fixed column 21.

A motor 24 is provided on the side wall of the fixed frame 2, and the output end of the motor 24 is connected to the driven gear 23. The fixed column 21 rotates in cooperation with the main gear 22 and the driven gear 23. The output end of the motor 24 drives the driven gear 23 to rotate. The driven gear 23 meshes with the main gear 22, transmitting power to the main gear 22, which in turn drives the fixed column 21 to rotate, causing the connecting frame 15 to rotate accordingly. This achieves the effect of adjusting the position of the industrial camera 13 in the horizontal direction and expanding the shooting range of the industrial camera 13.
[0036] Working principle: When the equipment starts working, the steel pipe is first placed on the operating table 1, and then the motor 12 is started. The output end of the motor 12 drives the full gear 11 to rotate. Since the full gear 11 and the rack 9 mesh with each other, the rotational motion of the full gear 11 is converted into the linear motion of the rack 9. The rack 9 drives the connecting column 5 to slide on the side wall of the slide plate 4 through the fixing block 8. At the same time, the connecting column 5 also slides synchronously in the transverse groove 3. As the connecting column 5 slides, the clamping plate 6 moves towards the middle to clamp the steel pipe. At this time, the rubber pad 7 on the side wall of the clamping plate 6 plays a role, increasing the friction between the clamping plate 6 and the steel pipe, thereby completing the fixed positioning of the steel pipe.
[0037] When the position and angle of the industrial camera 13 need to be adjusted, motor 2 19 is started. The output end of motor 2 19 drives the worm gear 18 to rotate. The worm gear 18 meshes with the worm wheel 17, transmitting the rotational motion to the worm wheel 17. The worm wheel 17 drives the rotating shaft 16 to rotate, thereby changing the angle of the connecting frame 14 and the industrial camera 13 to adapt to the shooting of the marking content at different positions. At the same time, motor 3 24 is started. The output end of motor 3 24 drives the driven gear 23 to rotate. The driven gear 23 meshes with the main gear 22, transmitting power to the main gear 22. The main gear 22 drives the fixed column 21 to rotate, causing the connecting frame 15 to rotate accordingly. Through this process, the position of the industrial camera 13 in the horizontal direction is adjusted, and the shooting range is expanded, thereby ensuring that the industrial camera 13 can clearly capture the marking image on the surface of the steel pipe, which is convenient for the subsequent processing system to analyze and identify the image.
