[0002] As an important component in construction projects, the quality and length of steel bars directly affect the structural performance and construction quality of the project. Therefore, before steel bars are processed and shipped out, they need to be weighed, measured in length, and marked. This information is not only used to identify steel bar specifications and performance parameters, but also provides reliable data support for subsequent construction, ensuring the correct use of steel bars and avoiding engineering risks caused by confusion or misuse of specifications. At the same time, marking information helps improve the efficiency of steel bar management and achieve seamless integration of production and construction.

[0003] However, in the prior art, weighing, measuring and marking of steel bars are usually completed in multiple independent steps, and the equipment in each step is independent of each other, and the transfer and positioning of the samples need to be done manually or by additional mechanical devices. This decentralized operation mode has the problems of complex operation process and low efficiency, which not only increases the manpower and time costs, but also easily leads to measurement data errors or inaccurate markings due to improper operation, making it difficult to meet the requirements of modern construction projects for efficient, accurate and automated steel bar processing. Summary of the invention

[0036] The first moving mechanism includes a motor 51, and the output end of the motor 51 drives the housing 6 to move along the substrate 3 through the driving rod. A telescopic rod is installed inside the housing 6, and the laser marker 7 is connected to the telescopic rod, and the telescopic rod is used to drive the laser marker 7 to move after operation.

[0037] In the present invention, the first moving mechanism includes a motor 51, the output end of which is connected to the shell 6 through a driving rod, and can drive the shell 6 to move precisely along the direction of the substrate 3, providing stable support for the positioning of the laser marker 7; a telescopic rod is installed inside the shell 6, and the laser marker 7 is connected to the telescopic rod. When the telescopic rod is in operation, the position of the laser marker 7 can be further adjusted, so that it can move flexibly in different directions, thereby adapting to steel bar samples 13 of different sizes and shapes, and ensuring the accuracy of the marking position and the marking quality.

[0038] The moving mechanism 2 8 includes a support 81, which is fixedly connected to the bottom of the base plate 3. A motor 2 82 is installed on one side of the support 81. A threaded rod 83 is fixed to the output end of the motor 82. The threaded rod 83 is inside the support 81, and a slide 2 84 is threadedly connected to the outer wall of the threaded rod 83. The slide 2 84 is slidably connected in the support 81. A support platform 85 is fixedly connected to the top of the slide 84, and the support platform 85 is connected to the weighing mechanism 9.

[0039] In the present invention, the moving mechanism 2 8 includes a support 81, which is fixedly connected to the bottom of the base plate 3 to provide a stable supporting structure; a motor 2 82 is installed on one side of the support 81, and the output end of the motor 2 82 is connected to a threaded rod 83, and the threaded rod 83 is arranged inside the support 81, and its outer wall is connected to a slide 2 84 through a thread, and the slide 2 84 can slide along the inside of the support 81 to achieve precise linear motion; the top of the slide 2 84 is fixedly connected to a support platform 85, and the support platform 85 is connected to the weighing mechanism 9. By driving the motor 2 82 to rotate the threaded rod 83, the weighing mechanism 9 can be driven to move, so that the steel bar sample 13 can adjust its position more flexibly and accurately during weighing and subsequent length measurement, thereby improving the convenience of operation and measurement accuracy.

[0040] The weighing mechanism 9 includes a platform 91, and vertical plates 92 are fixedly connected to both sides of the top surface of the platform 91. The vertical plates 92 are used to support the steel bar sample 13. The weighing sensor is located between the support 85 and the platform 91. The top surfaces of the vertical plates 92 on both sides are provided with a plurality of V-shaped grooves.

[0041] In the present invention, the weighing mechanism 9 includes a platform 91, and vertical plates 92 are fixedly connected to both sides of the top surface of the platform 91. The vertical plates 92 are used to provide stable support for the steel sample 13 to ensure that the sample remains stable during the weighing process; the weighing sensor is arranged between the support 85 and the platform 91, and the high-precision measurement of the weight of the steel sample 13 is achieved by accurately detecting the mass change of the platform 91; a plurality of V-shaped grooves are provided on the top surface of the vertical plate 92, and these grooves can better fix the steel sample 13 of different diameters to prevent it from shifting during weighing or moving, thereby improving the stability of weighing and the reliability of measurement.

[0042] A plurality of small holes 12 are provided in the middle of the detection frame 10 , and the photoelectric sensors 11 are coaxially arranged with the small holes 12 .

[0043] In the present invention, a plurality of small holes 12 are provided in the middle of the detection frame 10, and the small holes 12 are coaxially arranged with the photoelectric sensor 11. Through this structural design, when the steel bar sample 13 moves above the detection frame 10, the small holes 12 can accurately guide the light, so that the photoelectric sensor 11 can efficiently detect the shielding of the steel bar sample 13. This design not only improves the sensitivity and accuracy of the detection, but also provides reliable technical support for the accurate calculation of the steel bar length.

[0044] A through hole is provided in the middle of the base plate 3, and the support platform 85 is slidably connected in the through hole. Both sides of the outer wall of the support platform 85 are fixedly connected with folding plates 14, and the far sides of the folding plates 14 on both sides are fixedly connected to the two sides of the inner wall of the through hole. A switch door 2 is installed on the outer wall of the body 1.

[0045] In the present invention, a through hole is opened in the middle of the base plate 3, and the support 85 is slidably connected in the through hole. The movement of the support 85 realizes the smooth and accurate position adjustment of the steel sample 13 during the weighing and testing process through the through hole; the two sides of the outer wall of the support 85 are fixedly connected with folding plates 14, and the far sides of the folding plates 14 are respectively fixedly connected to the two sides of the inner wall of the through hole. When the support 85 slides, the folding plate 14 on one side will be folded and the other side will be stretched, thereby effectively shielding the through hole, preventing the debris generated during the movement or marking of the steel sample 13 from falling into the inside of the machine body 1, and ensuring the cleanliness of the device and the stability of operation.

[0046] Working principle: When in use, in the initial state of the weighing mechanism 9, the weight sensor records the mass value of the weighing mechanism 9 as T0. When the first steel bar sample 13 is placed, the weight sensor records the total mass of the weighing mechanism 9 and the first steel bar sample 13 as T1. The mass of the first steel bar sample 13 can be obtained by calculating T1-T0. Similarly, the steel bar samples 13 are placed one by one, the total mass value is recorded, and the weight of each steel bar sample 13 is obtained one by one by the same calculation method.

[0047] After the steel bar weight measurement is completed, the moving mechanism is driven to operate. At this time, the second motor 82 is started, driving the threaded rod 83 to rotate, thereby driving the second slide 84 and the support 85 to slide along the support 81, and then driving the weighing mechanism 9 to move as a whole, so that the steel bar sample 13 moves to one side of the detection frame 10. When one end of the steel bar sample 13 moves to the top of the small hole 12 in the middle of the detection frame 10, since the small hole 12 and the photoelectric sensor 11 are coaxially arranged, the steel bar sample 13 will block the photoelectric sensor 11 at this time. At this time, the blocked time is recorded, and the time of multiple steel bar samples 13 is recorded. Then, the second motor 82 is driven in the reverse direction to drive the threaded rod 83 to reverse, so that the steel bar sample 13 moves to the detection frame 10 on the other side, and then the time when the steel bar sample 13 blocks the photoelectric sensor 11 on the other side is recorded, and the time when each steel bar sample 13 blocks the photoelectric sensor 11 on the other side is recorded respectively, and then the length of each steel bar is calculated by the known motor speed;

[0048] When the quality and length detection is completed, the laser marker 7 is driven to mark the corresponding quality and length data on the corresponding steel bar sample 13, and during marking, the driving motor 51 can drive the driving rod to run, and the driving rod can drive the slide 52 to slide along the bracket 4, thereby driving the shell 6 and the laser marker 7 to move, so that they are close to or away from the steel bar sample 13. When marking the steel bar sample 13 with a larger diameter, the laser marker 7 is moved away from the steel bar sample 13, and when marking the steel bar sample 13 with a smaller diameter, the laser marker 7 is moved close to the steel bar sample 13. During marking, the telescopic rod can also be driven to drive the laser marker 7 to move further, and different positions of the steel bar sample 13 can be marked. When the support 85 moves, since the folding plates 14 are installed on its side, when the support 85 moves toward one side of the base plate 3, the folding plates 14 on one side will be folded, and the folding plates 14 on the other side will be stretched, so the through holes on the base can be blocked to prevent the debris on the steel bar or the debris generated by marking from falling into the interior of the steel bar and affecting the operation of the device.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
