Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle frame longitudinal beam cleaning, and more particularly, relates to a vehicle frame longitudinal beam cleaning system and method. Background Art

[0002] Frame rails are a crucial component of the vehicle frame. They are typically stamped or roll-formed, with a channel-shaped cross-section. For welded frames, the frame rails consist of a box-shaped structure consisting of inner and outer channel-shaped rails. These rails are then arc-welded to form a rail assembly, which is then welded or assembled with the crossbeams to complete the frame.

[0003] Since the inner and outer longitudinal beam pieces are formed by stamping or rolling processes, the surface of the longitudinal beam pieces contains a large amount of oil, dust, processing chips and other dirt after forming. During the welding process of the inner / outer longitudinal beam pieces to form the longitudinal beam assembly, welding defects such as pores and cracks are easily caused. Therefore, the inner / outer longitudinal beam pieces need to be cleaned before welding.

[0004] Frame rails are long, typically reaching nearly the entire vehicle length, reaching 5-7 meters. Currently, most rail component manufacturers remove surface dirt by manually wiping or spraying with cleaning solvents. However, these traditional methods present numerous challenges. Manual wiping is inefficient and difficult to guarantee, often missing hard-to-reach areas. Spraying with cleaning solvents can pollute the environment, negatively impacting air quality and operator health. Summary of the Invention

Through the reasonable layout and coordinated operation of the longitudinal beam loading system, the longitudinal beam lifting and handling system, the ultrasonic cleaning system and the longitudinal beam unloading system, the whole process from loading to cleaning to unloading is automated, which significantly improves the cleaning efficiency, reduces manual operation, and reduces labor intensity and safety risks. The ultrasonic cleaning system utilizes the cavitation effect generated by high-frequency sound waves to efficiently remove dirt on the surface of the longitudinal beam without damaging the workpiece surface, which not only improves the cleaning quality, but also reduces the cleaning time and improves production efficiency. The ultrasonic cleaning system is combined with automatic control, and the cleaning parameters can be adjusted according to different cleaning needs to further optimize the cleaning effect.

A first limiting plate 124 is provided at the two end portions of the first longitudinal frame 121, and a limiting groove matching the first longitudinal beam rail 112 is provided at the bottom of the first limiting plate 124, which is used to limit the left and right shaking of the loading trolley 12 during operation to ensure transportation safety.

[0046] like Figure 3As shown, the longitudinal beam lifting and handling system 2 includes a support frame 21 and a horizontal traveling crane 22 provided at the bottom of the support frame 21. The support frame 21 includes two longitudinal support frames 212 arranged parallel to each other, and slide grooves are provided on the two side walls of the longitudinal support frames 212. A transverse support frame 213 is fixedly installed between the two ends of the two parallel longitudinal support frames 212. The longitudinal support frames 212 and the transverse support frames 213 constitute a square support frame, forming a stable frame structure that can effectively bear the weight during the lifting and handling process and ensure the stability of the system. The four corners of the square support frame are provided with columns 211.

[0048] like Figure 4 As shown, the ultrasonic cleaning system 3 includes a cleaning mechanism 31, a rinsing mechanism 32, a passivation mechanism 33 and a cleaning control system 34. The cleaning mechanism 31, the rinsing mechanism 32 and the passivation mechanism 33 are arranged at the lower part of the longitudinal beam lifting and handling system 2 at one time. The cleaning control system 34 is arranged on the side of the ultrasonic cleaning system 3. The cleaning mechanism 31, the rinsing mechanism 32 and the passivation mechanism 33 are arranged in sequence to form a modular cleaning process, realizing the integrated operation of cleaning, rinsing and passivation, improving cleaning efficiency, reducing manual intervention, and reducing operational risks.

[0049] Furthermore, the cleaning mechanism 31 includes a cleaning tank 311 and an ultrasonic generator 313. The cleaning tank 311 is a rectangular trough structure made of stainless steel with good corrosion resistance. It can adapt to the use requirements of various cleaning liquids and extend the service life of the equipment. A plurality of vibration plates 312 are provided at the bottom of the cleaning tank 311, and a plurality of ultrasonic generators 313 are provided inside the cleaning control system 34. Each of the vibration plates 312 is electrically connected to each of the ultrasonic generators 313 to convert the high-frequency oscillation electrical signal generated by the ultrasonic generator 313 into high-frequency mechanical vibration and transmit it to the cleaning liquid. The cavitation effect is used to efficiently remove dirt on the surface of the longitudinal beam, especially for complex shapes and difficult-to-reach areas. The cleaning control system centrally controls the ultrasonic generator to ensure the stability and consistency of the cleaning process, which is convenient for operation and maintenance.

[0050] Furthermore, a circulating filtration device 314 is installed on the outside of the cleaning tank 311. The device consists of a centrifugal pump and a filter. The centrifugal pump uses the centrifugal force generated by its high-speed rotation to suck the cleaning liquid from the cleaning tank 311 and transport it to the filter. The filter is used to filter the cleaning liquid containing dirt. The filtered clean liquid then flows back to the cleaning tank 311 through the pipeline, realizing the recycling of the cleaning liquid.

[0051] The rinsing mechanism 32 includes a rinsing tank 321 and a bubbling device 322. The rinsing tank 321 is a rectangular trough structure made of stainless steel, has good corrosion resistance, can adapt to the use requirements of various cleaning liquids, and extends the service life of the equipment; the bubbling device 322 is arranged on the side of the rinsing tank 321. The device connects the rinsing tank 321 with the passivation mechanism 33 through a conveying pipeline, and uses the high-temperature water vapor generated by the passivation mechanism 33 to generate a large number of bubbles in the rinsing tank 321, thereby improving the rinsing effect of the longitudinal beam piece and can efficiently remove residual stains on the surface of the longitudinal beam piece.

[0052] Furthermore, the passivation mechanism 33 includes a passivation tank 331 , a heating device 332 and an exhaust device 333 . The passivation tank 331 adopts a rectangular trough structure and is made of stainless steel. It has good corrosion resistance and can adapt to the use requirements of various passivation liquids, thereby extending the service life of the equipment; the heating device 332 is fixedly installed at the bottom of the passivation tank 331 and is composed of several groups of electric heating tubes for heating the passivation liquid to produce a passivation film on the surface of the longitudinal beam to improve the corrosion resistance of the longitudinal beam; the exhaust device 333 is arranged on the side of the passivation tank 331 and is composed of a centrifugal fan and a pipeline. The input end of the centrifugal fan is connected to the passivation mechanism 33, and the output end of the centrifugal fan is connected to one end of the pipeline. The other end of the pipeline is connected to the bubbling device 322 of the rinsing mechanism 32. The exhaust device 333 extracts the water vapor generated above the passivation liquid in the passivation tank 331 and transports it to the bubbling device 322. Bubbles are generated in the rinsing tank 321 through the bubbling device 322 to provide hot steam support for the rinsing process.

[0053] The cleaning mechanism 31, rinsing mechanism 32, and passivation mechanism 33 are electrically connected to a cleaning control system 34 for transmitting control and feedback signals. Sensors (such as temperature sensors, liquid level sensors, and pressure sensors) are installed in each mechanism to monitor the equipment's operating status in real time. These sensors transmit the data they detect to the control system 34, which then makes real-time adjustments based on this data. The cleaning control system 34 stores preset cleaning programs designed to meet specific cleaning and process requirements. These programs include parameters such as ultrasonic frequency, power, cleaning time, and the temperature and time for rinsing and passivation. The cleaning control system 34 automatically controls the operation of each mechanism according to the preset program. For example, when a longitudinal beam enters the cleaning tank 311, the cleaning control system 34 automatically activates the ultrasonic generator 313 and the circulating filter 314. After cleaning is complete, the system automatically switches to the rinsing program. The cleaning control system 34 is equipped with an operation panel or touch screen, allowing the operator to manually start, stop, and adjust the cleaning process. The operation panel typically includes buttons, a display, and an alarm indicator. The operator can adjust the cleaning parameters, such as ultrasonic power, cleaning time, and rinse temperature, through the operation panel according to actual conditions. These adjustments will be immediately reflected in the operating status of each mechanism. The control system 34 monitors the working status of each mechanism in real time, including key parameters such as temperature, liquid level, and ultrasonic power. Once an abnormality is detected, such as equipment failure or parameter deviation from the set value, the control system will issue an alarm and automatically shut down. The cleaning control system 34 records the parameters and operating status of each cleaning, including data such as cleaning time, ultrasonic power, temperature, and liquid level. These records can be used for production management and quality control. When problems arise, operators can retrieve historical data through the control system for tracing and analysis to optimize the cleaning process.

The unloading trolley 42 runs on the track to realize efficient transportation of longitudinal beam sheets, reduce manual operation, reduce labor intensity, and provide reliable material support for subsequent processes.

[0055] Furthermore, the unloading trolley 42 includes a second longitudinal frame 421 arranged on the top of the second longitudinal beam rail 413, and a second transverse frame 422 is fixedly installed between the two ends of the second longitudinal frame 421. The second longitudinal frame 421 and the second transverse frame 422 form a square trolley frame for carrying and transporting material frame equipment. A second roller 423 is fixedly installed near the two end ends at the bottom of each second longitudinal frame 421, and the second roller 423 abuts against the second longitudinal beam rail 412.

[0056] Furthermore, a drain pan 43 is provided at the bottom of the second longitudinal beam rail 412, the side of which is aligned with the end of the second longitudinal beam rail 412 and extends into the interior of the support frame 21, for receiving the liquid remaining after the longitudinal beam piece is cleaned, preventing the liquid from dripping and contaminating the ground, thereby keeping the working environment clean and reducing safety hazards such as slipping.

[0057] Furthermore, the longitudinal beam blanking system 4 also includes a blowing device 44, which is arranged on the side of the drain pan 43 and is used to blow low-temperature compressed air onto the surface of the longitudinal beam lifted by the electric hoist sling 224 and the horizontal walking hanger 22, so that the passivation liquid on the surface of the longitudinal beam can evaporate and dry quickly, so that the longitudinal beam can be cooled and dried.

[0060] S100: placing a material frame filled with longitudinal beams to be cleaned onto the loading trolley 12 and transporting it to the loading position; a certain number of longitudinal beams are lifted from the material frame by the electric hoist 224 of the longitudinal beam lifting and handling system 2, and transported to the ultrasonic cleaning system 3 via the horizontal traveling hanger 22;

[0061] S200: Utilize the multiple vibration plates 312 arranged in the cleaning structure 31 of the ultrasonic cleaning system 3 to convert the high-frequency oscillation electrical signal generated by the ultrasonic generator 313 into high-frequency mechanical vibration and transmit it to the cleaning liquid, thereby removing the oil, dust, machining chips, floating rust, etc. on the surface of the longitudinal beam and suspending them in the water. The cleaning liquid containing dirt is then filtered through the circulation filter device 314 outside the cleaning tank 311 and then flows back into the cleaning tank 311;

[0062] S300: After the stringer piece is cleaned, the horizontal traveling hanger 22 is used to lift the stringer piece from the cleaning tank 311 and transport it to the rinsing mechanism 32. The high-temperature steam generated by the passivation mechanism 33 generates a large number of bubbles in the rinsing tank 321 to remove the residual stains on the surface of the stringer piece so that they do not affect the subsequent passivation of the stringer piece.

[0063] S400: After the longitudinal beam piece is rinsed, the longitudinal beam piece is lifted from the rinsing tank 321 by the horizontal traveling hanger 22 and transported to the passivation mechanism 33. The passivation liquid is heated by the heating device 332 to form a passivation film on the surface of the longitudinal beam piece, thereby improving the corrosion resistance of the longitudinal beam piece.

[0064] S500: After the longitudinal beam is passivated, the longitudinal beam is lifted out of the passivation tank 331 by the horizontal traveling hanger 22, and placed above the drain pan 43. Low-temperature compressed air is blown onto the surface of the longitudinal beam through the blowing device 44 outside the passivation tank 331, so that the passivation liquid on the surface of the longitudinal beam is quickly evaporated and dried, and the longitudinal beam is cooled and dried.

[0065] S600: Place the dried longitudinal beam pieces into the material frame device on the unloading trolley 42 through the horizontal traveling hanger 22, and the unloading trolley 42 transports them to the unloading station.

[0066] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
