Description

Technical Field

[0001] The present invention relates to the field of vehicle body paint removal, and particularly to a laser paint removal system for vehicle bodies. Background Art

[0002] With the rapid development of the automotive industry and manufacturing, traditional painting and repair technologies are facing more and more challenges. Especially in the process of accident vehicle repair, used car spare parts refurbishment, and surface treatment of other metal parts, there are certain defects in traditional manual paint removal and rust removal methods. Manual sanding for paint removal not only has a high working intensity and low efficiency, but also easily causes secondary damage to the vehicle body surface or metal spare parts, affecting the subsequent painting quality and the service life of metal parts. In addition, traditional methods usually generate a large amount of dust and waste, posing a potential threat to the environment and the health of operators.

[0003] In order to improve the quality and efficiency of automotive repair and metal surface treatment, laser paint removal technology, as a new surface treatment process, has gradually been widely used. The laser paint removal system precisely removes the paint layer or rust by a high-energy laser beam, not only avoiding the possible surface damage in traditional manual paint removal, but also being able to complete the paint removal task of complex-shaped objects in a relatively short time.

[0004] The existing technologies for laser paint removal mainly focus on the paint removal operation in the whole vehicle production line during the automotive production process, and do not involve the actual needs of accident vehicle repair, used car spare parts refurbishment, and other metal surface treatments. In these fields, traditional manual paint removal still dominates, resulting in time-consuming and laborious paint removal processes, and it is difficult to avoid environmental pollution and safety hazards. Therefore, it is particularly important to develop a laser paint removal system suitable for accident vehicle repair, used part refurbishment, and other metal surface treatments.

[0005] In addition, even if the paint removal system in the whole vehicle production line is directly applied to the automotive repair production line, there are the following problems:

[0006] The laser paint removal devices in the existing technologies are usually designed for the standardized whole vehicle production line, and mostly for the treatment of flat or simple-shaped vehicle body surfaces. However, during the accident vehicle repair process, the vehicle body is often deformed, with complex curved surfaces, uneven areas, and inaccessible parts. This makes it possible that the existing laser paint removal systems may not accurately cover these complex parts during the repair process, resulting in uneven paint removal or the inability to completely remove certain paint layers or rust.

[0007] Existing laser paint removal devices are usually fixed-configured or semi-automated designs, making it difficult to adapt to changing repair requirements. For example, when repairing different types of vehicles or spare parts, it may be necessary to adjust the laser power, scanning speed, or the position of the laser head, etc. Existing systems often require manual adjustment, which not only increases the operation difficulty but also reduces the flexibility and adaptability of the system in actual production. Especially when repairing accident vehicles, the rapid switching and adjustment of the repair process are crucial. Summary of the Invention

[0008] The purpose of the present invention is to provide a vehicle body laser paint removal system, which adopts the configuration of a double-station paint removal mechanism and a dust and smoke removal mechanism. The double-station design enables the repair work to be carried out in parallel, effectively improving the production capacity of vehicle body repair and metal surface treatment, and is particularly suitable for high-efficiency and large-scale production environments; in addition, the double-station paint removal mechanism is equipped with a robotic arm, a laser paint removal head, a vehicle body recognition device, etc., which can automatically adapt to different curved surfaces and complex structures of the vehicle body, accurately control the laser scanning path, ensure that the vehicle body will not be damaged secondarily during the repair process of accident vehicles, and can efficiently remove the paint layer or rust.

[0038] Please refer to Figure 1 , Figure 3 , Figure 4, in this embodiment, the double-station paint removal mechanism is arranged inside the isolation fence 3. The double-station paint removal mechanism includes two sets of paint removal components 4 arranged oppositely. Each paint removal component 4 includes a carrier 401, a first walking servo 402, a ground rail frame 403, a base 404, a second walking servo 405, a robotic arm 406, a laser paint removal head 407 and a vehicle body recognition device 408. The carrier 401 is arranged directly above the ground rail groove 2, and the carrier 401 moves along the length direction of the ground rail groove 2 through the first walking servo 402; the ground rail frame 403 is installed on the carrier 401 through a frame, a base 404 is arranged on the ground rail frame 403, and a laser generator 410 and a second walking servo 405 for driving it to move along the ground rail frame 403 are installed on the base 404; the robotic arm 406 is installed on the base 404 through a servo turntable 409, and the laser paint removal head 407 and the vehicle body recognition device 408 are installed at the execution end of the robotic arm 406.

[0040] The working process of the vehicle body recognition device 408 in this embodiment:

[0041] Vehicle body scanning and data acquisition: The vehicle body recognition device 408 (such as a CCD vision recognizer, a laser scanner, a glossmeter or a multispectral imaging system) first scans or photographs the vehicle body surface to obtain the state information of the paint layer in real time, including data such as paint layer thickness, damage, scratches, and dents.

[0042] Data processing and analysis: The recognition device transmits the collected data to the control system, and the control system processes and analyzes the data according to different scanning modes (for example, three-dimensional data processing or gloss analysis).

[0044] Automatically control the paint removal process: According to the generated three-dimensional paint layer thickness model, the control system adjusts the working parameters of the laser paint removal head 407 (such as power, frequency, scanning mode, etc.), and guides the robotic arm 406 to accurately move the laser paint removal head 407 to the predetermined area to start the paint removal operation.

[0045] The real-time feedback function of the vehicle body recognition device 408 can ensure the accuracy and effect during the paint removal process, ensuring that the paint removal work only acts on the target area and will not affect other parts.

[0046] Real-time adjustment and correction: During the paint removal process, the vehicle body recognition device 408 continuously monitors the paint removal progress and adjusts the position and parameters of the laser paint removal head 407 through a feedback mechanism to ensure the uniformity and quality of the paint surface treatment.

[0047] In this embodiment, the ground rail frame 403 is a U-shaped ground rail. The ground rail frames 403 of the two paint removal assemblies 4 are complementary.

When the two ground rail frames 403 of the paint removal assemblies 4 approach, they combine to form an annular ground rail system. The complementary setting means that these two paint removal assemblies 4 can work together in the spatial layout, complementing each other and forming a complementary working area. This setting can improve the working efficiency of the system and avoid bottleneck problems that may occur in a single workstation.

A suction fan is arranged inside the suction hood 507. The upper side of the suction hood 507 is connected to the external dust and smoke purifier through the suction pipe 508.

[0049] In this embodiment, multiple non-contact temperature alarms and smoke concentration alarms are also provided on the bottom side of the cover body of the suction hood 507. The non-contact temperature alarms and smoke concentration alarms are used to warn of situations such as too high temperature and too high smoke concentration during laser paint removal.

[0064] Please refer to Figure 2, in combination with the above embodiments, the present invention also proposes the working steps of the above laser paint removal system, including the following:

[0065] 1) Vehicle body transportation and positioning:

[0066] Use a forklift, an AGV transport vehicle or a transplant vehicle to transport the accident vehicle or the metal part to be processed to the working area of the system. Then, the ground rail frame 403 of the double-station paint removal mechanism is driven by the first walking servo 402, and the ground rail frames 403 of the two paint removal assemblies 4 are in a separated state, facilitating the entry of the vehicle body.

[0067] 2) Vehicle body recognition and modeling: Once the vehicle body enters the working area, the vehicle body recognition device 408 scans the paint surface to be repaired of the vehicle body under the coordination of the first servo, the second servo and the robotic arm 406, that is, uses technologies such as CCD vision recognition, laser scanning, and gloss meter to perform a detailed recognition of the vehicle body surface; the console 6 generates a three-dimensional paint surface model of the vehicle body according to the vehicle body scanning information, including information such as paint thickness and material type, providing data support for subsequent laser paint removal.

[0068] 3) Start of laser paint removal: The console 6 automatically adjusts the working parameters of the double-station paint removal mechanism according to the three-dimensional paint surface model of the vehicle body to ensure that the laser power, frequency, etc. of the laser paint removal head 407 are adapted to different parts of the vehicle body; the robotic arm 406 and the laser paint removal head 407 of the double-station paint removal mechanism work together and move precisely along the vehicle body surface. The laser beam removes the paint layer by layer through high-energy pulses. During the laser paint removal process, parameters such as the power and frequency of the laser generator 410 are automatically adjusted according to the thickness and type of the paint to reduce energy consumption and avoid unnecessary damage to the metal part.

[0069] 4) Dust and smoke removal treatment: The dust and waste gas generated during the laser paint removal process are effectively treated by the dust and smoke removal mechanism 5. The dust removal device uses a high-efficiency dust suction fan to ensure that the dust is sucked away in time during paint removal and is treated by an external dust and smoke purifier, ensuring that the air quality in the workshop meets environmental protection standards and avoiding pollution.

[0070] 5) Real-time monitoring and data feedback: The console 6 real-time monitors various data during the laser paint removal process, including laser power, working progress, dust concentration, etc. If an abnormal situation occurs (such as too high dust concentration or too high temperature, etc.), the system will automatically alarm and adjust the paint removal process to ensure safety and process quality.

[0071] 6) Completion of paint removal and inspection: Once the laser paint removal task is completed, the double-station paint removal mechanism stops working. The console 6 automatically checks the paint removal situation of the vehicle body, and uses the vehicle body recognition device 408 to perform subsequent detection on the paint surface to ensure that the paint removal effect meets the standards. Finally, the double-station paint removal mechanism resets to the starting position.

[0072] 7) Vehicle / Metal Part Removal and Subsequent Processing: When all the paint stripping work is completed, the vehicle body or metal parts are removed from the processing area by forklifts, AGV transporters, etc. for subsequent painting or refurbishment. The console 6 saves and records the paint stripping data, process parameters, etc. of the whole vehicle, providing data support for subsequent repair or quality control.

[0073] Through the automated and efficient laser paint stripping process, combined with the synergistic effect of the double-station paint stripping mechanism and the dust and smoke removal mechanism 5, the above embodiments provide a fast, precise, and environmentally friendly paint stripping technology for the surfaces of vehicle bodies and metal parts. Through the centralized management and intelligent adjustment of the console 6, the efficiency, stability, and environmental friendliness of the entire paint stripping process are ensured, and the quality and efficiency of accident vehicle repair, used car spare part refurbishment, and other metal part surface treatments can be effectively improved.

[0074] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
