Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a steel plate pretreatment cleaning equipment based on laser rust removal. Background Art

[0002] The widespread application of laser cleaning technology in steel plate pretreatment, with its high efficiency and environmental friendliness, has significantly improved the quality and efficiency of rust removal processes. However, during laser treatment, after rust is removed from the steel plate's surface, some fine rust can easily remain on the conveyor belt or steel plate surface due to airflow disturbances or conveyor belt vibrations. This residual rust can adhere to subsequent steel plates, affecting the quality of subsequent processes and reducing production efficiency.

[0003] Traditional cleaning methods, such as mechanical sweeping or negative pressure vacuuming, can alleviate this problem to a certain extent, but they still have obvious shortcomings. Mechanical cleaning devices (such as brush rollers or scrapers) are easily worn out due to long-term friction, need to be replaced frequently, and are less effective in removing fine rust. Negative pressure vacuuming systems consume a lot of energy and are affected by the stability of the airflow, which may lead to incomplete rust removal or even secondary diffusion. Therefore, there is an urgent need for a steel plate pretreatment and cleaning equipment based on laser rust removal to solve the problem of rust remaining on the conveyor belt or steel plate in the existing technology, affecting the quality of subsequent processes. Summary of the Invention

A ball assembly is provided at the edge of the anti-rust baffle, and the ball assembly rolls and abuts against the edge of the conveyor belt.

[0013] Furthermore, an anti-rust baffle is provided in the laser rust removal chamber.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See also Figure 1-Figure 7 A preferred embodiment of the present invention is a steel plate pretreatment and cleaning device based on laser rust removal, which includes a conveyor belt 1, a laser generating device 2 and an air knife 4.

[0033] The conveyor belt 1 includes a belt body 101 and multiple rollers 102; the belt body 101 is used to support and transport steel plates; the multiple rollers 102 are arranged at intervals along the conveying direction, and the belt body 101 is mounted outside the multiple rollers 102; the laser generating device 2 is used to perform laser rust removal on the steel plates carried on the conveyor belt 1, wherein a laser rust removal chamber 3 is formed between the conveying plane of the belt body 101 and the laser generating device 2; the air knife 4 is horizontally arranged in the laser rust removal chamber 3 and extends along the conveying direction of the conveyor belt 1, and the air outlet of the air knife 4 is facing the side edge of the conveying plane of the belt body 101, and is used to generate airflow to remove rust remaining on the surface of the belt body 101 or the steel plate.

[0034] The belt body 101 of the conveyor belt 1 circulates under the support of multiple rollers 102 arranged at intervals along the conveying direction, forming a flat conveying plane to stably carry and continuously transport the steel plate; when the steel plate enters the laser rust removal chamber 3 composed of the conveying plane and the laser generating device 2 along the conveyor belt 1, the laser generating device 2 generates a laser beam with a specific power and frequency, and accurately peels off the oxide layer and rust on the surface of the steel plate through thermal effect and shock wave effect; at the same time, the horizontally arranged wind knife 4 extends along the conveyor belt 1, and a high-speed airflow is generated at the air outlet of the wind knife 4 toward the belt body 101. On the one hand, this airflow completely removes the loose rust generated by the laser treatment from the surface of the steel plate, and on the other hand, forms an airflow barrier on the conveying plane of the belt body 101 to prevent the rust from being deposited again on the surface of the conveyor belt 1; the rust-removed steel plate continues to move with the conveyor belt 1 to the next process, and the peeled rust is blown into the matching rust cleaning device by the direction of the airflow.

[0035] Based on the continuous transportation mode of steel plates on the conveyor belt, the continuous flow operation of the steel plate rust removal process is realized. Compared with the traditional intermittent rust removal method, the production efficiency is significantly improved, which is particularly suitable for the mass production needs of modern intelligent manufacturing production lines.

[0036] Based on the rust removal method of the laser generator 2, this solution adopts a process route of non-contact laser processing combined with airflow cleaning, which effectively avoids the wear problem of traditional mechanical rust removal on workpieces and equipment, significantly reduces the frequency of equipment maintenance, extends the service life of key components, reduces the company's investment costs, and improves economic benefits.

[0037] Based on the method of using air knife 4 to clean rust, an efficient directional airflow field can be formed by optimizing the design of air outlet angle and air pressure parameters, ensuring that the surface of the steel plate after laser rust removal reaches the residue-free cleaning standard and avoiding rust residue on the conveyor belt 1, providing reliable guarantee for subsequent precision processing or high-quality surface treatment.

[0038] The traditional conveyor belt 1 is prone to damage in some cases. For example, in order to further improve production efficiency and reduce the laser accuracy to significantly increase the rust removal area, a detachable metal tray assembly is installed on the surface of the conveyor belt 1. Each tray is provided with a positioning groove that matches the size of the steel plate, which can completely block the direct exposure of the laser beam to the conveyor belt 1 body, avoiding ablation damage to the belt body 101 material due to laser scattering, greatly improving the service life of the conveyor belt 1. At the same time, the rust removal operation area can be expanded to more than 95% of the full width of the conveyor belt 1, thereby improving the rust removal efficiency.

[0039] If the steel plate to be processed is large, when the equipment is running, due to the continuous operation of the laser generating device 2, the temperature is often in a high state. In the traditional conveyor belt 1, not only will the rubber belt body 101 be prone to thermal aging, leading to hardening and cracking; the high temperature will also accelerate the volatilization of the grease of the roller 102 bearing, increasing the risk of mechanical wear. In this case, a chain plate conveyor belt 1 can be used to replace the traditional roller 102 conveyor belt 1. The chain plate conveyor belt 1 is spliced ​​by stainless steel chain plates. With the tight bite between the chain plates, the operating stability is greatly improved. It can also withstand heavier steel plates and reduce the rust removal deviation caused by the shaking of the belt body 101. In addition, the surface of the chain plate is specially treated with high friction, which can effectively prevent the steel plate from sliding during transportation. At the same time, the chain plate has strong wear resistance and is not easily damaged under the irradiation of the laser, which extends the service life of the conveyor belt 1.

[0040] If the laser generator 2 operates continuously for too long, the output power will be unstable, causing the rust removal effect to fluctuate. To address this problem, the laser generator 2 can be equipped with a power monitoring module to set the output power value. When the output power fluctuates, the control module can adjust it in real time to keep it close to the preset value. To further improve the rust removal efficiency, multiple laser generators 2 can be provided to increase the area of ​​rust removal per unit time, while reducing the operating time of each laser generator 2 to enhance its stability.

[0041] In order to better improve the quality of the product, an intelligent air pressure control system should be introduced into the wind knife 4. According to the conveying speed and thickness of the steel plate and the actual needs of laser rust removal, the air pressure of the wind knife 4 can be adjusted in real time to achieve precise control of the rust cleaning process, while also reducing production energy consumption. In the design and selection of the wind knife 4, the appropriate specifications of the wind knife 4 can be flexibly selected according to different production scales and steel plate sizes. For production lines that process small steel plates, a narrow wind knife 4 with dense air outlets is selected to ensure that the airflow can accurately cover the surface of the steel plate, reducing energy consumption while achieving efficient rust removal; and for large steel plates, a wide, high-power wind knife 4 can quickly blow away large areas of rust, greatly improving cleaning efficiency.

[0042] In order to prevent the steel plate from being oxidized due to excessive contact with air before entering the next process after rust removal, preferably, the air knife 4 is connected to an inert gas source through a pipeline. Such as argon, nitrogen and helium. When the air knife 4 blows out the inert gas, a tight gas protection film is quickly formed on the surface of the steel plate, which effectively isolates the steel plate from the contact with oxygen in the air, and fundamentally inhibits the oxidation of the steel plate during the interval between the two processes. In addition, this design optimizes the production process, reduces the need for additional remedial measures such as secondary rust removal due to re-oxidation of the steel plate, shortens the production cycle, and improves production efficiency. At the same time, compared with traditional rust prevention methods, the use of an inert gas source avoids tedious processes such as applying rust inhibitors, reduces the use and residue of chemical agents, reduces production costs, and complies with the green and environmentally friendly production concept, helping companies build a cleaner and more efficient production environment.

[0043] In order to further improve the flexibility of the laser generating device 2, preferably, the laser generating device 2 is connected to a first motor 5, which is used to drive the laser generating device 2 to swing in a conveying direction perpendicular to the conveyor belt 1 to adjust the laser irradiation angle. The laser generating device 2 is driven to swing by the first motor 5, which greatly improves the accuracy and comprehensiveness of the rust removal operation. When faced with steel plates with complex surface structures, curvatures or special shapes, the laser generating device 2 can flexibly adjust the irradiation angle so that the laser beam covers the surface of the steel plate in all directions, ensuring that every rust mark can be accurately removed, effectively avoiding the problem of incomplete rust removal due to blind angles of irradiation, and significantly improving the quality of rust removal. This design also greatly expands the scope of application of the equipment. During the production process, different batches of steel plates may have differences in size, shape and material. The swingable characteristics of the laser generating device 2 enable it to quickly adapt to these changes without the need for complex re-debugging or replacement of components of the equipment, reducing the threshold for equipment use and maintenance costs. At the same time, precise angle control enables the laser to act on the surface of the steel plate at the optimal incident angle, giving full play to the rust removal efficiency of the laser. Under the premise of ensuring the quality of rust removal, the operating power of the laser generator is reduced, thereby reducing the energy consumption of the equipment and extending the service life of the equipment, so that enterprises can easily cope with diversified production needs, quickly respond to market changes, and enhance the competitiveness and adaptability of enterprises in the market. The first motor 5 can be selected from different categories according to needs. For example, when higher precision is required, a stepper motor can be used, and it can be used with a frequency converter and an encoder. When only the approximate rust removal range needs to be determined and the precision requirements are low, a servo motor can be selected, which has its own angle feedback and is simple to control.

[0044] The laser generator 2 can also move in the conveyor belt 1's direction of travel. This can be coordinated with the conveyor belt 1's speed during the rust removal process, further improving rust removal efficiency. Preferably, the first motor 5 is interlocked with a slider 6, which is threadedly connected to a lead screw 7 extending in the conveyor belt 1's direction of travel. The lead screw is connected to a second motor 8, which drives the lead screw back and forth in the conveyor belt 1's direction of travel. Thanks to the coordinated operation of the first and second motors 5 and 8, the laser generator 2 can flexibly move in both vertical and horizontal directions, significantly enhancing the automation and intelligence of the rust removal process. In actual production, the second motor 8 can precisely control the laser generator 2's speed in the conveyor belt 1's direction of travel, ensuring that the laser beam is always focused on the treated area of ​​the steel plate. This avoids rust removal omissions or duplicated operations caused by deviations in the laser irradiation position, significantly improving rust removal efficiency. The connection between the lead screw 7 and the slider 6 improves the smoothness and precision of the laser generator 2's movement along the conveyor belt 1, reducing control complexity and preventing complex operations that could damage production equipment due to errors.

[0045] In order to prevent rust from being blown off the surface of the conveyor belt 1 and the steel plate by the air knife 4 and then accidentally entering between the roller 102 and the belt body 101, preferably, an anti-rust baffle 9 is further provided in the laser rust removal chamber 3. The anti-rust baffle 9 extends along the width direction of the conveyor belt 1 and is located on the opposite side of the air outlet of the air knife 4. A ball assembly 10 is provided at the edge of the anti-rust baffle 9, and the ball assembly 10 rolls and abuts against the edge of the belt body 101. The anti-rust baffle 9 abuts against the belt body 101 of the conveyor belt 1 to a certain degree, preventing the belt body 101 from running. At the same time, the rolling abutment design of the ball assembly 10 and the edge of the conveyor belt 1 ensures a close fit between the baffle and the conveyor belt 1, enhancing the rust-blocking effect, while not causing additional resistance to the normal operation of the conveyor belt 1. It not only avoids damage to the conveyor belt 1 caused by friction, but also absorbs rust and prevents it from spreading again under the action of the air knife 4.

[0046] In addition, the anti-rust baffle 9 not only abuts against the edge of the conveyor belt 1, but preferably, an anti-rust baffle 9 is also provided in the laser rust removal chamber 3. The anti-rust baffle 9 extends along the width of the conveyor belt 1 and is located on the opposite side of the air outlet of the wind knife 4. It is also placed between the belt body 101 and the roller 102. The anti-rust baffle 9 rolls against the belt body 101 and the roller 102 respectively through the ball assembly 10. The anti-rust baffle 9 is placed between the belt body 101 and the roller 102, which constructs a more stringent rust barrier system than the anti-rust baffle 9 abutting against the edge of the belt body 101. This layout greatly reduces the channel for rust to enter the gap between the roller 102 and the belt body 101, eliminating the possibility of rust particles invading key parts of the equipment at the source, further reducing the probability of failure of the roller 102 and the conveyor belt 1 due to rust wear, significantly extending the overall service life of the equipment, and reducing long-term operation and maintenance costs.

[0047] To better treat rust that is blown onto the rust-proof baffle 9 by the air knife 4, the rust-proof baffle 9 is preferably connected to a rust-cleaning device. This device comprises a rust collection guide tube 11 and a water pipe 12. One end of the rust collection guide tube 11 is connected to the rust-proof baffle 9, while the other end is in sealed communication with the water pipe 12. Rust on the rust-proof baffle 9 flows through the collection guide tube into the water pipe 12, where it is carried away from the laser rust removal chamber 3, preventing rust from accumulating on the rust-proof baffle 9. Furthermore, to more closely track the rust removal, an electromagnet is mounted on the rust-proof baffle 9. The electromagnet is configurable for on / off intervals, and its magnetic force can be increased or decreased based on the amount of rust. When energized, the electromagnet attracts rust, causing it to adhere to the vicinity of the rust-proof baffle 9. When de-energized, the accumulated rust falls into the collection guide tube. In addition, a flow sensor and a pressure regulating device are installed inside the water pipe 12, which can adjust the water flow rate and pressure in real time according to the amount of rust collected, ensuring that the rust can be discharged smoothly, avoiding pipe blockage, and ensuring the efficient and stable operation of the rust cleaning work, thereby greatly improving the automation level and operational reliability of the equipment.

[0048] To better recycle resources, the water pipe 12 is preferably interconnected with a water pump 13 and a water tank 14. The water tank 14 is equipped with a filter screen 15 that is horizontal to the bottom of the water tank 14. The inlet of the water tank 14, the filter screen, and the outlet of the water tank 14 are sequentially connected along the height direction. When water enters the inlet of the water tank 14, it first contacts the filter screen 15, where impurities such as rust are intercepted. Clean water then flows smoothly through the filter screen 15 and flows to the outlet of the water tank 14, rejoining the rust cleaning cycle. Rust itself will also settle at the bottom of the water tank 14 due to gravity, without clogging the filter screen and thus affecting the filtering effect. However, because fine impurities cannot pass through the filter screen 15, the water quality will become very turbid if the circulation time is too long. Therefore, a water quality monitoring sensor can be installed in the water to monitor key indicators such as turbidity and pH of the water in the water tank 14 in real time. If the water quality parameters exceed the preset range, the system will immediately issue an alarm, reminding the staff to clean the water tank 14 or replace the filter screen.

[0049] To facilitate the replacement and cleaning of the water and accumulated rust in the water tank 14, a cleaning door 16 is preferably provided on the sidewall of the water tank 14 between the filter 15 and the bottom of the water tank 14. The provision of cleaning door 16 greatly simplifies the cleaning process of the water tank 14. When the water and accumulated rust in the water tank 14 need to be replaced or cleaned, the operator simply opens the cleaning door 16 and easily accesses the accumulated rust at the bottom of the water tank 14, quickly removing it with specialized tools. Simultaneously, the wastewater in the water tank 14 can be quickly drained through the cleaning door 16, significantly reducing cleaning time and significantly improving work efficiency. During daily operation, regular opening of the cleaning door 16 for inspection and cleaning can promptly identify potential damage or blockages within the water tank 14, enabling preventive maintenance and ensuring stable operation of the equipment. Furthermore, this design creates a safer working environment for operators, preventing health risks associated with direct contact with wastewater and rust. The cleaning door 16 is also equipped with a handle for easy opening and closing.

[0050] Furthermore, to prevent the precipitated rust from being disturbed by the water flow and affecting the filtering effect of the filter, a magnetic device 17 is preferably connected to the surface of the cleaning door 16 facing the interior of the water tank 14. During the daily operation of the water tank 14, the magnetic device 17 continues to function, firmly absorbing the rust settled at the bottom of the water tank 14. The outlet path of the water pipe 12 passes through the inner wall of the cleaning door 16, allowing the magnet to better absorb the rust. When the water pump 13 drives the water circulation, even if the water flow is significantly disturbed, the rust fixed by the magnetic device 17 will not roll with the water flow, preventing rust particles from impacting and clogging the filter, greatly extending the effective service life of the filter, reducing the frequency of filter replacement, and thus reducing equipment maintenance costs. In addition, when the staff opens the cleaning door 16 for cleaning, the rust attracted by the magnetic device 17 will be concentrated near the cleaning door 16, making it convenient for the staff to quickly collect and handle it, significantly improving cleaning efficiency. At the same time, this centralized cleaning method reduces the possibility of rust being scattered throughout the water tank 14, further reducing the risk of rust contaminating other parts of the equipment.

[0051] The file storage auxiliary device of the present invention has but is not limited to the following technical effects:

[0052] 1. Conveyor belt 1 transports steel plates for laser rust removal, ensuring continuous production and a stable assembly line operation. Steel plates enter the laser rust removal area at a constant speed via conveyor belt 1. Laser generator 2 and air knife system 4 work together to achieve seamless transport, rust removal, and cleaning. This continuous production not only significantly increases throughput per unit time but also ensures highly consistent rust removal quality for each steel plate, eliminating quality fluctuations that could be caused by manual intervention.

[0053] 2. The equipment achieves continuous assembly line operation through the coordinated operation of the laser generator 2, air knife 4, and conveyor belt 1, significantly improving rust removal efficiency. Air knife 4, connected to an inert gas source, forms a protective gas film on the steel plate surface, preventing secondary oxidation and providing high-quality blanks for subsequent processing, thereby improving product yield.

[0054] 3. The first motor 5 of the laser generator 2 drives vertical oscillation, while the second motor 8 achieves synchronous horizontal movement via the lead screw slider 6, ensuring full laser coverage of complex curved surfaces and eliminating blind spots. A built-in power monitoring module calibrates output in real time, and combined with multi-laser rotation, it avoids fluctuations caused by long-term operation and ensures consistent rust removal quality.

[0055] 4. The rust cleaning system realizes the full process automation management of rust from stripping to recycling through the three-level coordination of "air blowing + baffle + water flushing", which not only ensures the immediate effect of laser rust removal, but also solves the pain point that rust chips are difficult to completely remove in traditional equipment.
