Description

Technical Field

[0001] The utility model relates to the field of laser technology, in particular to a scrap steel laser rapid rust removal device and rust removal equipment thereof. Background Art

[0002] Steel is an alloy composed of iron and carbon, which easily reacts chemically with oxygen in the air or humid environment to produce iron oxide, that is, rust; specifically, when the surface of steel is exposed to air or water, the iron on the surface reacts with oxygen or oxygen in water to form iron oxide, that is, the common red rust; this rust will continue to spread and eventually lead to corrosion and damage of steel.

[0003] Laser rust removal is an advanced surface cleaning technology that uses a laser beam to irradiate the surface of the object being processed with high energy density. Dirt, oxides, rust and other substances on the surface are evaporated or crushed, thereby achieving surface cleaning and repair. Laser rust removal is fast, which means that a large number of metal surfaces can be processed in a short time, and laser rust removal maintains the original state of the workpiece, thereby extending the service life of the metal; the development and application expansion of laser rust removal technology will play a greater role in metal processing, manufacturing, cultural relics protection and other fields. It not only improves efficiency and quality, but also provides a sustainable solution for environmental protection.

[0004] The patent "A laser rust removal device and a laser rust removal method" (publication number CN116371824A, hereinafter referred to as prior art 1) discloses a laser rust removal device, which uses a conveyor belt device to move the steel to be rusted in a horizontal direction, so that its laser head can perform rust removal processing on a certain area of ​​the steel to be rusted; its laser head can perform rotation angle processing through a laser transmission device; and a swing fan device is also used, which drives multiple fans to rotate around the connecting shaft to achieve rough cleaning of scrap steel attachments at multiple angles. The laser rust removal equipment of prior art 1 moves with the scrap steel to complete rust removal in multiple ranges of the scrap steel. However, the scrap steel is heavy, and the power required to move it must be sufficient. Such operation is wasteful and inconvenient for the overall device. Because during processing, the laser beam contacts the surface of the scrap steel, the photothermal effect will cause the movement of the scrap steel, which will affect the accuracy and efficiency of rust removal. Moreover, the cleaning structure used is only a cleaning fan, which can only clean less rust dust and cannot blow away more rust dust. The two ends of the frame of the laser rust removal equipment are also limited in position, and processing cannot be performed on larger sizes or sizes exceeding the limited range.

[0037] The movable limiting frame 33 is fixed in position by fastening bolts 37; the movable limiting frame 33 can be arranged at the same height as the displacement mechanism, or its height can be arranged below the working surface 12 and through the guide rails arranged at the bottom of the brackets on both sides of the base 11, and an inverted or suspended arrangement will not interfere with the cleaning frame 31 from performing all-round cleaning; if it is arranged at the top, it will be at the same height as the cleaning frame 31 and the first displacement mechanism 41, which will affect the rust removal work of the rust removal device.

[0038] The two sides of the scrap steel 1 are respectively restricted in movement by a limit seat 13 and a limit frame 33, and the scrap steel 1 and the limit seat 13 are arranged in contact; the other side is limited by a corner limit block 32 installed on the mobile limit frame 33 and a corner limit block 32 set at the end of the workbench, and the corner limit block 32 is clamped at the corner of the scrap steel 1 so that it is restricted in the corner limit block 32.

[0039] Laser rust removal technology is to generate a laser beam through a laser generator and transmit it to the laser head through an optical fiber. The laser head focuses the laser beam on the metal surface through a focusing lens to form a small irradiation point. The laser beam produces a strong thermal effect and photomechanical effect on the rust layer on the metal surface at the irradiation point, causing the rust layer to heat up rapidly and undergo physical or chemical changes. As the laser beam scans, the rust layer is gradually vaporized or melted and blown away by the high-speed airflow to expose the metal body. The utility model has the function of flexibly adjusting the size of scrap steel. During the laser rust removal process, when the laser beam contacts the surface of the scrap steel 1, due to the photothermal effect, it may cause a slight movement of the scrap steel, which will affect the accuracy and efficiency of rust removal. In order to solve this problem, we have specially equipped the workbench with a limit mechanism to ensure the stability of the scrap steel during the processing process. These limit mechanisms are made of high-strength materials, have a sturdy structure, and can firmly fix the scrap steel to prevent it from moving during the laser processing process. The design of the limit mechanism also takes into account scrap steel of different sizes and shapes, and can adapt to the sizes of various scrap steels through simple adjustments to ensure the accuracy and efficiency of laser rust removal.

At the same time, a sensor and a control system can be provided between the displacement mechanism and the rust removal mechanism, which can monitor the rust removal on the scrap steel surface in real time, and adjust the position and power of the laser transmitter according to the actual situation to achieve the best rust removal effect. In addition, the scrap steel laser rapid rust removal device can also include safety protection devices, such as laser protective covers, protective glasses, etc., to ensure the safety of the operator. At the same time, the device should also be equipped with an exhaust gas treatment device to treat the exhaust gas generated during the rust removal process to protect the environment.
