Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehouse automation technology, and in particular to a steel pipe positioning and coding device based on a vertical truss. Background Technology
[0002] Steel pipes are one of the core basic materials of modern industry and are widely used in fields such as oil and gas transportation, building structure support, machinery manufacturing, power equipment and nuclear energy facilities. In the field of automated steel pipe processing, achieving efficient and accurate inkjet printing has always been a technical challenge. Traditional processes rely on decentralized equipment to complete the positioning, size measurement, surface treatment and marking of steel pipes, which has significant drawbacks.
[0003] Firstly, the traditional method involves highly fragmented processes, with positioning, ranging, surface pretreatment, and coding being separate procedures. Before coding, additional equipment is needed for surface rust removal and grinding, and the steel pipes require multiple transfers. The processing cycle for a single steel pipe is long, resulting in very low efficiency. Furthermore, the separate equipment arrangement can cause positional shifts during steel pipe transfer, leading to reduced coding accuracy. Finally, the multiple processes require additional equipment or manual intervention, resulting in higher production costs. To address these issues, the industry urgently needs a multi-functional integrated device that combines positioning, ranging, pretreatment, and coding to overcome the bottleneck of fragmented processes and achieve synergistic optimization of accuracy and cost. Therefore, we propose a steel pipe positioning and coding device based on a vertical truss. Utility Model Content

[0006] The multi-functional integrated module includes a rangefinder, a surface pretreatment component, a blowing pipe, a coding machine, and a barcode scanning inspection camera, arranged sequentially from left to right along the bottom of the lifting rod and the direction of the vertical truss.

The V-shaped rollers have a concave arc surface in the middle and are arranged along the axial direction to support a single steel pipe and transport it to the end positioning top plate to complete the axial positioning correction.
[0008] Preferably, the rangefinder is linked with the end positioning top plate to measure the actual length of the steel pipe abutting the end positioning top plate.

[0022] Example
[0023] This embodiment provides a steel pipe positioning and marking device based on a vertical truss. Please refer to [link / reference]. Figures 1-2 The system includes a vertical truss 1, a lifting rod 101 that can move linearly and be raised and lowered, and a multi-functional integrated module 102 disposed at the bottom of the lifting rod 101; the multi-functional integrated module 102 includes a rangefinder 102a, a surface pretreatment component 102b, a blowing pipe 102c, a coding machine 102d, and a barcode scanning inspection camera 102e arranged sequentially from left to right along the direction of the vertical truss 1 at the bottom of the lifting rod 101; and a steel pipe positioning mechanism 2, including multiple sets of V-shaped rollers 201, and an end positioning top plate 202 disposed at the end of the V-shaped rollers 201. The V-shaped rollers 201 have a concave arc surface in the middle and are arranged along the axial direction to support a single steel pipe and transport it to the end positioning top plate 202 to complete the axial positioning correction.
[0024] The rangefinder 102a is linked with the end positioning plate 202 to measure the actual length of the steel pipe abutting the end positioning plate 202; the surface pretreatment component 102b is linked with the blowing pipe 102c to automatically blow away debris after grinding; the blowing pipe 102c sprays air in the opposite direction to the marking machine 102d; the surface pretreatment component 102b includes a grinding belt 102b-1 and a grinding motor 102b-2 that drives the grinding belt 102b-1, and the grinding belt contacts the surface of the steel pipe at an angle of 20-35°; the marking machine 102d has an marking depth of 0.1-0.3mm, and the generated identification code includes information such as production batch, specifications, actual length, and warehousing time and location.
[0025] It should be noted that the vertical truss 1 adopts a column-type frame, and the lifting rod 101 achieves vertical lifting by driving the ball screw through a servo motor. At the same time, the lifting rod 101 also has the function of horizontal movement along the truss guide rail. The multi-functional integrated module 102 is fixed at the bottom of the lifting rod 101, integrating five major functional components. The vertical truss 1 can realize the three-dimensional spatial positioning of the functional area and adapt to the processing requirements of different steel pipes.
[0026] The steel pipe positioning mechanism 2 realizes the positioning and auxiliary length measurement functions of the steel pipe. The V-shaped roller 201 adopts a concave arc surface design (arc radius matches the curvature of the steel pipe). The distance between the rollers is constant and they are arranged side by side to support a single steel pipe. An end positioning top plate 202 is set at the end of the roller to limit the position of the end face of the steel pipe for easy length measurement. After the steel pipe enters the V-shaped roller 201, the concave arc surface automatically corrects the axis to ensure no deviation during the conveying process. The V-shaped roller 201 is driven by the motor to rotate the roller and use friction to send the steel pipe to the end positioning top plate 202 until the steel pipe is in contact with the end positioning top plate 202. At this time, the distance measuring instrument 102a starts to measure the distance.
[0027] The rangefinder 102a is a laser rangefinder, which is installed on the far left of the module, that is, the side closest to the end positioning top plate 202. It includes a contact part. When the lifting rod 101 moves along the truss, the contact part contacts the end face of the steel pipe. Then the laser rangefinder emits a laser to the reflective surface of the end positioning top plate 202. The actual length of the steel pipe can be calculated by combining the position of the top plate. The measured length is automatically entered into the system and the measured length data information is reflected in the identification code.
[0028] The surface pretreatment component 102b uses a grinding motor 102b-2 to drive the grinding belt 102b-1 to contact the steel pipe surface at a 25° angle. The grinding belt 102b-1 uses a sanding belt. The angled design can increase the grinding area, avoid belt jamming, and ensure uniform grinding. The pretreatment can remove oxide scale and rust, and improve the adhesion strength of the inkjet printing. At the same time, the blow pipe 102c is linked to the pretreatment. After grinding, it automatically sprays air to remove residual debris and dust. The air spray direction is diagonally to the left (opposite to the coding machine) to prevent debris from contaminating the coding area and avoid blurry or missing dots in the inkjet printing. The reverse design ensures that dust stays away from the coding machine lens.
[0029] The 102d coding machine can generate a unique identification code for steel pipes, including production batch, specifications, measured length, warehousing time, and storage location code. The coding depth is 0.2mm. The identification code can store data for the entire process and supports scanning for traceability. Finally, the 102e scanning inspection camera captures the identification code to verify the clarity and accuracy of the content. The 102e coding inspection camera is equipped with a CCD camera, which automatically verifies and identifies the identification code and matches it with the database. In case of an anomaly, it triggers repeated verification. After multiple verification failures, it automatically triggers an alarm signal.
[0030] In summary, this embodiment of a steel pipe positioning and coding device based on a vertical truss integrates a rangefinder, surface pretreatment components, a blowing pipe, a coding machine, and a barcode scanning inspection camera into a vertical truss. It works in synergistic control with a steel pipe positioning machine to integrate the traditionally dispersed five processes into a continuous automated process. By using a lifting rod to linearly move along the truss and continuously switch processes, the processing cycle for a single steel pipe is significantly shortened, efficiency is significantly improved, the equipment footprint is reduced, and the degree of automation is high. Furthermore, based on the linkage measurement of the actual length of the steel pipe using a rangefinder and an end positioning top plate, combined with grinding belt tilt angle control and reverse spraying of the blowing pipe, the coding offset rate is significantly reduced, and the debris removal rate, barcode inspection pass rate, and marking information integrity rate are all greatly improved, meeting the requirements for high-precision warehouse traceability.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
