Description

TECHNICAL FIELD

[0001] The utility model belongs to welding processing technical field, especially relate to a laser cleaning device for steel wire rod. BACKGROUND

[0002] Wire rod is an important raw material for manufacturing solid welding wire. With the substantial increase in demand for lightweight equipment in China, the production of high-strength steel welding wire has also increased day by day, and it has been widely used in the fields of heavy-duty crane supports, transport ships, port machinery, etc. However, in order to ensure the quality of the subsequent processing of the welding wire, the surface of the high-strength steel welding wire needs to be kept clean during the production process, and ultimately the cleanliness of the weld and the suppression of defects can be ensured.

[0003] In industrial production, the existing wire rod cleaning methods mainly include sand blasting cleaning and chemical solvent cleaning. Sand blasting cleaning uses high-speed sand particles to impact the surface of the wire rod to remove contaminants such as rust and oil. However, this method has many drawbacks. On the one hand, the sand blasting process produces a large amount of dust, causing serious environmental pollution and harming the health of operators; on the other hand, the impact of sand particles can cause wear to the wire rod substrate, reducing the mechanical properties and surface quality of the wire rod, and affecting subsequent processing and product quality.

[0004] Chemical solvent cleaning uses chemical reagents to react with contaminants on the surface of the wire rod to achieve the purpose of cleaning. However, chemical solvents are usually volatile and corrosive, not only polluting the air and water sources, but also possibly leaving chemical residues on the surface of the wire rod, causing corrosion problems. In addition, the disposal of waste liquid after chemical solvent cleaning is costly, and improper disposal can have long-term negative effects on the ecological environment.

[0005] Laser cleaning, as a new technology, has significant advantages. It uses high-frequency high-energy laser pulses to directly irradiate the surface of the workpiece, causing the oil stains, rust, plating or coating on the surface of the workpiece to absorb the focused laser energy in an instant, resulting in volatilization or detachment, thereby achieving the purpose of quickly and efficiently eliminating surface attachments or surface coatings. Its non-polluting nature avoids damage to the environment, and the non-contact cleaning process does not cause wear to the wire rod substrate, effectively maintaining the integrity and physical properties of the wire rod, and the cleaning speed is fast and efficient, which can greatly shorten the cleaning cycle, and also allows for precise cleaning of small areas on the surface of the wire rod, ensuring cleaning quality.

[0006] Most of the existing laser cleaning devices are designed for flat or simple-shaped workpieces, and it is difficult to meet the cleaning needs of the wire rod which is long and flexible. The wire rod needs to be stably transmitted and accurately positioned during the cleaning process, and at the same time, it is necessary to ensure that the laser can uniformly cover each part of the surface. The conventional laser cleaning equipment cannot effectively fix the wire rod and make it pass through the laser action area at a constant speed, and it is also difficult to ensure that each position of the wire rod can be cleaned, which may lead to incomplete or uneven cleaning. Practical new type content

[0007] Therefore, the utility model aims at providing a laser cleaning device for steel wire rod to solve the problem that the existing laser cleaning equipment cannot be used for cleaning the steel wire rod.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a laser cleaning device for steel wire rod, it includes conveying mechanism and laser cleaning mechanism, the conveying mechanism quantity is two, two conveying mechanisms are arranged at the both sides of laser cleaning mechanism respectively, the laser cleaning mechanism includes laser, inner circle rotating wheel ring and outer circle rotating wheel ring, the number of laser is multiple, multiple lasers are uniformly distributed on the inner circle rotating wheel ring along the circumferential direction, the inner circle rotating wheel ring is rotatably embedded in the inner part of the outer circle rotating wheel ring, the inner circle rotating wheel ring is connected with the driver, the steel wire rod is placed on the conveying mechanism, the steel wire rod passes through the center of the inner circle rotating wheel ring.

[0009] Further, the conveying mechanism includes a transmission base, a transmission shaft and a conveyor belt, the transmission base is rotatably connected with the two transmission shafts respectively on both sides, the two transmission shafts are connected through the conveyor belt, the steel wire rod is placed on the conveyor belt.

[0010] Further, a conveying groove is formed in the conveyor belt, and the steel wire rod is placed in the conveying groove.

[0011] Further, the conveying mechanism and the laser cleaning mechanism are arranged on the workbench.

[0012] Further, a support column is arranged below the outer circle rotating wheel ring, and the support column is connected with the workbench.

[0013] Further, a concave mounting groove is arranged on the upper surface of the workbench, and the transmission base and the support column are connected in the concave mounting groove.

[0014] Further, the driver is a motor.

[0015] Further, the number of lasers is four.

[0016] Further, the laser is electrically connected with a laser power adjusting device.

[0017] Further, the output end of the laser is provided with a focusing lens group.

[0018] Compared with the prior art, the beneficial effects of the present application are: in view of the problem of environmental pollution caused by the existing sand blasting and chemical solvent cleaning methods, the present application adopts laser cleaning technology, and no chemical cleaning agent or large amount of water resource is needed in the whole cleaning process, thus eliminating the generation of waste water, waste gas and chemical residues from the root, greatly reducing the pollution to the environment, and effectively protecting the ecological environment. The non-contact laser cleaning process of the present application avoids the wear and damage of the wire rod base caused by mechanical impact or chemical corrosion, ensures that the wire rod can maintain its original mechanical properties and surface quality after cleaning, lays a solid foundation for subsequent processing into high-quality high-strength steel welding wire, effectively guarantees the cleanliness and defect suppression effect of the weld, and significantly improves the quality reliability of the final product.

[0019] In order to solve the problem that the existing laser cleaning device cannot meet the cleaning requirements of the wire rod, the present application designs a conveying mechanism and a laser cleaning mechanism. In the conveying mechanism, the rotary connection of the transmission base and the transmission shaft and the setting of the conveying belt, especially the specially designed conveying groove on the conveying belt, can stably place the steel wire rod and ensure that it maintains a stable transmission state during the conveying process, effectively avoiding the shaking and deviation of the wire rod. At the same time, the two conveying mechanisms are arranged on both sides of the laser cleaning mechanism, so that the wire rod can be well guided and supported when entering and leaving the cleaning area. In the laser cleaning mechanism, a plurality of lasers are arranged along the circumferential direction of the inner ring rotating wheel ring, and the inner ring rotating wheel ring and the outer ring rotating wheel ring are nested and rotated, and the motor drives the inner ring rotating wheel ring, so that the lasers can clean the wire rod passing through the center of the inner ring rotating wheel ring in all directions and uniformly. Through this design, no matter how long the wire rod is, it can ensure that every part of its surface can fully receive laser irradiation, achieving thorough and uniform cleaning effect, effectively solving the problem of incomplete or uneven cleaning of the wire rod by conventional laser cleaning equipment.

[0020] Moreover, the lasers are electrically connected with the laser power adjusting device, which can flexibly and accurately adjust the laser power according to different types and thicknesses of pollutants on the surface of the wire rod, further optimize the cleaning effect, and improve the cleaning efficiency. At the same time, the focusing lens group at the output end of the laser can make the laser beam more concentrated on the surface of the wire rod, enhance the cleaning ability, and reduce unnecessary energy consumption under the premise of ensuring the cleaning quality.
