Description

Technical Field

[0001] This invention relates to the field of surface treatment, specifically to an intelligent peeling process for surface coatings on large aerospace components at the base level. Background Technology

[0002] During long-term service, aircraft surface coatings are prone to damage, aging, and corrosion due to the influence of the natural environment or their own characteristics. Therefore, base-level repairs require disassembling the aircraft and removing and repairing the surface coatings to meet flight requirements.

[0003] Currently, the removal of surface coatings from large, base-level aerospace components mainly relies on manual grinding or chemical paint removers. Chemical paint removal methods are prone to environmental pollution and human health hazards, and suffer from low efficiency, high cost, and inapplicability to composite materials. Manual grinding suffers from low efficiency, difficulty in quality control, and potential damage to the substrate, while also posing serious health risks. Therefore, from the perspectives of paint removal efficiency, quality, versatility, environmental protection, and occupational health, the use of chemical paint removal or manual grinding for component-level surface coating removal no longer meets the current needs of aircraft component repair. There is an urgent need to develop and utilize new coating removal technologies to achieve rapid, non-destructive, efficient, and environmentally friendly removal of surface coatings from large aerospace components. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes an intelligent peeling process for the surface coating of large aerospace components at the base level.

[0005] A smart peeling process for surface coatings on large, base-level aerospace components comprises the following steps:

[0006] S1. Inspection before paint removal:

[0007] a: Check if gasoline, kerosene, and alcohol have been drained from the components;

[0008] b: Inspect the surface of the components for severe oil stains and large-area damage;

[0009] c: Check if the antenna inside the radome is intact, ensuring there are no breaks or wear;

[0010] d: Check that there are no extraneous objects at the joints of the wing fuel tank openings, rudder, vertical tail, and horizontal tail components;

[0011] e: Whether the component substrate is deformed, has mechanical scratches, or has dents or other damage;

[0012] S2. Preparations before paint removal:

[0013] a: Inventory the quantity and condition of equipment, tools, fixtures, and aircraft parts;

[0014] b: Check and calibrate the remaining quantity of instruments, meters, and consumables such as tapes;

[0015] c: Install the components correctly and stably on the corresponding tooling, and use an indoor positioning system to determine the positioning accuracy, spatial coordinate system, and world coordinate system;

[0016] S3. Pre-painting protection: Protect the radome, wingtips, lower tail, rudder, horizontal tail, vertical tail, and outer wings separately.

[0017] S4. Pre-run checks:

[0018] a. Robot inspection: Regularly check for oil leaks; check for excessive gear backlash; check for damage to the cables between the control cabinet, purging unit, base, and robotic arm.

[0019] b. Sandblasting can inspection: Spray a small amount of soapy water on the interface of valves and joints. If no bubbles come out, it indicates that the airtightness is good.

[0020] c. Inspection of bottom guide rails and top rails;

[0021] d. Inspection of the sandblasting pipe;

[0022] e. Inspection of the vibrating screen;

[0023] S5, System Pre-boot:

[0024] a: Open all control cabinets in sequence, correctly powering on the main and auxiliary systems involved. Before powering on, ensure you are wearing complete personal protective equipment. When powering on, turn on the necessary switches in a standardized manner. After powering on, close the cabinet door promptly. Do not turn on switches incorrectly or arbitrarily. Pay attention to personal and equipment safety.

[0025] b: The electronic monitoring system will automatically display after being powered on. Log in to the control page to adjust the display screen, number of monitors and shooting parameters, and customize the display screen to meet production needs;

[0026] c: Log in to the electronic display system to automatically display the parameters of each system, switch the content of the demonstration screen and adjust the playback parameters according to production needs;

[0027] d: Log in to the host computer system corresponding to the robot, handle the error message, and first turn on the air compressor and air dryer to generate high-pressure air. After the high-pressure air pressure reaches the system preset value, switch to the parameter configuration page and input the process parameters in conjunction with the production components. Then turn on the safety monitoring system, dust removal system, sand return system, sand lifting system, pipeline system, and sandblasting system, observe whether the system is operating normally, and handle the system error message in a timely manner.

[0028] e: Turn on the vision system computer, and it will automatically enter the industrial camera screen; observe the camera display for any abnormalities, and check whether the screen parameter configuration and adjustment are normal;

[0029] f: After checking that there are no abnormalities in the communication between the safety door and the PLC, close the safety door of the robot's work area to ensure that it is in a closed state;

[0030] g: Turn on the robot controller switch and perform a cold start of the system for 15 minutes. Then, reset the system via the host computer. After processing the error message from the robot teach pendant, reset the system again. Select the appropriate program to clear the original system parameters, then select the automatic configuration program and run it. After the program runs without errors, place the teach pendant properly to avoid bumps and drops.

[0031] S6. System Automatic Operation:

[0032] a: Observe the monitoring screen of the host computer and confirm that all systems have entered the normal startup state. Then, match the production parts, select the robot running program, and load it. Check whether the content of the parameter setting page matches the actual production automatically.

[0033] b: Start the robot using the control panel. The robot will perform actions according to the program. The sandblasting time can be selected automatically or manually according to production needs to start the sandblasting and paint removal operation.

[0034] c: Based on the coating condition and paint removal requirements, observe the industrial camera footage during the operation and adjust the process parameters. Different peeling parameters are used for different parts.

[0035] Open the safety door when the automatic program has run to about 1 / 5 of its length; wear appropriate personal protective equipment before entering the sandblasting room, observe the peeling effect up close, and adjust the process parameters.

[0036] d: After automatic paint removal, turn off the system, observe the peeling effect and record it; for areas that are difficult to remove paint, such as tooling-covered areas, narrow gaps, and protruding parts, use a manual spray gun to remove paint. Before manual paint removal, the sandblasting tube should be replaced correctly and replaced promptly after manual sandblasting is completed.

[0037] S7. Clean after removal:

[0038] a: After the paint removal work is completed, remove the protective packaging, clean the dust from the surface of the parts, and ensure that the parts are clean and free of contamination;

[0039] S8, Inspection:

[0040] a: Appearance quality inspection is conducted using a 100% inspection method.

[0041] a1. If layered paint removal is performed, the coating surface after paint removal should not have a large area of ​​the next paint layer exposed, but local exposure of the substrate is allowed.

[0042] a2. If all paint is to be removed, the paint layer should be completely removed. For some special areas, the paint layer may be retained due to technical or process limitations. Non-painted areas should be well protected.

[0043] b: Use a 100% inspection method to check for foreign objects, including visual inspection, to ensure that the product after paint removal is free of protective tape, abrasive media, or other foreign objects.

[0044] c: Based on the previously completed technical feasibility assessment and process verification, no further assessment of the damage to the substrate caused by the paint removal process is required.

[0045] The step S3 described above requires cleaning the surface of the radome and the surrounding area of ​​the diversion strip two to three times with a clean cotton cloth soaked in anhydrous ethanol. After cleaning, use special protective tape for protection.

[0046] The protection of the antenna inside the radome in step S3 requires the use of cable ties to secure the antenna inside the radome to ensure that it does not move during the paint removal process.

[0047] The protection of the radome pin holes and pitot tube mounting base in step S3 requires using pins to plug the pin holes and attaching a layer of protective tape of the same size to the pin surface to prevent the pins from falling off during the paint removal operation.

[0048] The protection of the wingtip in step S3 requires stuffing the inside area of ​​the wingtip with cotton cloth and securing it with masking tape; the protection of the drooping tail in step S3 requires taping the area with a larger slit.

[0049] In step S3, for the rudder, a special protective plate for the rudder docking surface needs to be used to secure it firmly, and then tape is used to stick the protective plate to the narrow gap area between the protective plate and the fuselage surface; for the vertical tail, a special protective plate needs to be used on the vertical tail docking surface and lower wall panel and secured firmly, and then tape is used to stick the protective plate to the narrow gap area between the protective plate and the fuselage surface.

[0050] In step S3, after the horizontal stabilizer is securely fixed with a special protective plate for the horizontal stabilizer docking surface, tape is used to stick the protective plate to the narrow gap area between the protective plate and the fuselage surface; for the outer wing, after the outer wing docking surface is securely fixed with a special protective plate for the outer wing, tape is used to stick the protective plate to the narrow gap area between the protective plate and the fuselage surface.

[0051] The inspection in step S4c specifically includes visually inspecting whether the markings on the anchor bolts have shifted; checking whether the surfaces of the rack and guide rail are damaged due to wear or abrasive blasting to ensure the precise operation of the robot's external axes; checking whether the output gears are worn and inspecting the mechanical components; checking whether the automatic lubrication system is leaking and checking the fluid level to determine whether replacement is needed.

[0052] The inspection in step S4d specifically includes visually inspecting all hoses for signs of wear through; any hose pierced by abrasive must be replaced immediately; inspecting the couplers connecting all different hoses; ensuring the hooks are reliably connected and that safety pins are installed on each coupler to prevent accidental disengagement; and checking the two gaskets for wear to ensure proper sandblasting conditions and to prevent additional wear or damage to adjacent components.

[0053] The inspection in step S4e specifically includes checking whether all fasteners are fully tightened and whether the screen surface is damaged; checking whether the vibrator bearings are lubricated on schedule; and checking and eliminating any blockages or foreign objects between the screen and fixed objects such as chutes and funnels that may affect the normal use of the screen.

[0054] The beneficial effects of this invention are: based on the intelligent peeling system for coatings of ultra-large and complex aircraft structural components, it can realize the automatic removal of surface coatings of complex structural components such as aircraft radomes, outer wings, vertical tails, and horizontal tails. In terms of paint removal capability, paint removal quality, paint removal efficiency, and energy saving and environmental protection, it far surpasses existing manual grinding or chemical paint removal technologies, solves the problem of surface coating removal of components in aviation repair systems, and greatly improves the level of automation in aviation equipment repair.

[0090]

[0091] Open the safety door when the automatic program has run to about 1 / 5 of its length; wear appropriate personal protective equipment before entering the sandblasting room, observe the peeling effect up close, and adjust the process parameters.

[0097] a1. If layered paint removal is performed, the coating surface after paint removal should not have a large area of ​​the next paint layer exposed, but local exposure of the substrate is allowed.

[0101] The step S3 described above requires cleaning the surface of the radome and the surrounding area of ​​the diversion strip two to three times with a clean cotton cloth soaked in anhydrous ethanol. After cleaning, use special protective tape for protection.

[0102] Specifically, the width of the special protective tape is larger than that of the diverter strip, and its protective effect is as follows: when the radar dome is upright, the left side of the tape overlaps with the left side of the diverter strip, and the right side of the tape naturally adheres to the paint surface. After the tape is pasted, it is repeatedly pressed until it is tightly adhered.

[0103] Specifically, it may be necessary to apply two layers of tape depending on the situation.

[0104] The protection of the antenna inside the radome in step S3 requires the use of cable ties to secure the antenna inside the radome to ensure that it does not move during the paint removal process.

[0105] The protection of the radome pin holes and pitot tube mounting base in step S3 requires using pins to plug the pin holes and attaching a layer of protective tape of the same size to the pin surface to prevent the pins from falling off during the paint removal operation.

[0106] Specifically, simply roll up a cloth to the same diameter as the pitot tube mounting bracket and insert it.

[0107] The protection of the wingtip in step S3 requires stuffing the inside area of ​​the wingtip with cotton cloth and securing it with masking tape.

[0108] The protection of the drooping tail in step S3 can be achieved by applying tape to the area with a larger slit.

[0109] In step S3, the rudder needs to be securely fixed with a special protective plate for the rudder mating surface, and then the narrow gap between the protective plate and the surface of the fuselage is glued with tape.

[0110] In step S3, after the horizontal tail needs to be securely fixed with a special protective plate for the horizontal tail docking surface, tape is used to stick the protective plate to the narrow gap area between the protective plate and the surface of the machine body.

[0111] Specifically, the original cover is used to protect the tailgate opening.

[0112] The protection of the vertical tail in step S3 requires the use of a special protective plate on the vertical tail docking surface and lower wall panel, which must be securely fixed before tape is used to adhere the protective plate to the narrow gap area between the protective plate and the machine body surface.

[0113] Specifically, the original cover is used to protect the tail section.

[0114] The protection of the outer wing in step S3 requires using a special protective plate for the outer wing docking surface to secure it firmly, and then using tape to stick the protective plate to the narrow gap area between the protective plate and the fuselage surface.

[0115] Specifically, the original aircraft cover is used for protection at the outer wing opening.

[0116] Specifically, the intelligent coating stripping system based on the ultra-large and complex structural components of aircraft can automatically remove the surface coatings of complex structural components such as radomes, outer wings, vertical tails, and horizontal tails. In terms of paint removal capability, paint removal quality, paint removal efficiency, and energy saving and environmental protection, it far surpasses the existing manual grinding or chemical paint removal technology, solves the problem of surface coating removal of components in aviation repair systems, and greatly improves the level of automation in aviation equipment repair.
