Description

Technical Field

[0001] The invention relates to the technical field of brake beam cleaning, and in particular to a brake beam laser cleaning system. Background Art

[0002] The brake beam is an important component in the braking system of railway vehicles. In order to ensure the reliability and safety of the brake beam, it is necessary to inspect and clean it regularly, especially to inspect the stress-bearing areas at the roots of both ends of the brake beam to check whether there are cracks. Since the surface of the brake beam is prone to rust, the roots must be thoroughly derusted and cleaned before flaw detection. At present, shot blasting rust removal equipment is mainly used for rust removal and cleaning of brake beams. However, the rust removal effect of shot blasting rust removal equipment is unstable and the reliability is poor. Some equipment has serious shot leakage and is prone to dust pollution. Compared with traditional shot blasting cleaning, laser cleaning technology, as an efficient and environmentally friendly modern cleaning method, can effectively utilize the interaction between high-energy laser beams and the rust layer on the surface of the brake beam, and has obvious advantages in cleaning the rust on the surface of the brake beam.

[0003] During the cleaning process of the brake beam by the laser cleaning system, the rust removal and cleaning operations at the root of the brake beam are usually carried out on a conveyor line. Since the height of the conveyor line is fixed and the distance from the ground is limited, the laser cleaning equipment is subject to space constraints when approaching the root of the brake beam, and cannot accurately locate the part that needs to be cleaned, resulting in inconvenience in removing rust from the root of the brake beam. At the same time, during the cleaning process, some brake beams are damaged or deformed, resulting in their structural dimensions exceeding the scope of use. Even after rust removal and cleaning, their normal use functions cannot be restored, further reducing the cleaning efficiency. Summary of the invention

At the same time, it can detect whether the structural dimensions of the brake beam 100 meet the standard range before cleaning, thereby improving the cleaning quality and cleaning efficiency. The brake beam laser cleaning system is used to screen and clean the brake beam 100 before cleaning, and includes a conveying mechanism 1, a centering mechanism 2, a laser cleaning mechanism 3, a detection mechanism 4 and an auxiliary cleaning mechanism 5, wherein the brake beam 100 is placed on the conveying mechanism 1, and the conveying mechanism 1 can drive the brake beam 100 to move in the direction of the loading area, the cleaning area and the unloading area of ​​the conveying mechanism 1; the centering mechanism 2 is symmetrically arranged on both sides of the loading area, and is used for centering and correcting the brake beam 100 along the central axis of the conveying mechanism 1; the laser cleaning mechanism 3 is symmetrically and positionally adjustable on both sides of the cleaning area, and is used for cleaning both ends of the brake beam 100; the detection mechanism The structure 4 is located between the laser cleaning mechanism 3 and the centering mechanism 2, and is used to detect the shape of the brake beam 100 to be cleaned; the auxiliary cleaning mechanism 5 includes a lifting component 51 and a visual measurement component 52, and the lifting component 51 is symmetrically arranged below both sides of the cleaning area, and is used to lift the brake beam 100 to the working height position of the laser cleaning mechanism 3; the visual measurement component 52 is arranged above the cleaning area and on the central axis of the conveying mechanism 1, and is used to detect the positions of the two ends of the brake beam 100. The visual measurement component 52 is electrically connected to the laser cleaning mechanism 3, and the laser cleaning mechanism 3 can adjust the cleaning position according to the detection result of the visual measurement component 52.

[0036] The brake beam 100 to be cleaned is placed on the conveying mechanism 1, and the conveying mechanism 1 moves it to the loading area. The centering mechanism 2 is symmetrically arranged on both sides of the loading area, and the position of the brake beam 100 is adjusted to be centered along the central axis of the conveying mechanism 1; then, the conveying mechanism 1 continues to convey the brake beam 100 to be cleaned to the bottom of the detection mechanism 4, and the detection mechanism 4 determines whether its size meets the cleaning standard, and moves the one that meets the cleaning standard to the cleaning area; thereafter, the brake beam 100 is supported to the working height position of the laser cleaning mechanism 3 by the lifting component 51, and the image recognition technology of the visual measurement component 52 is used to detect the position coordinates of the two ends of the brake beam 100 in real time. Since the visual measurement component 52 is electrically connected to the laser cleaning mechanism 3, the visual measurement component 52 can transmit the detected position information of the two ends of the brake beam 100 to the laser cleaning mechanism 3 through electrical signals. The laser cleaning mechanism 3 adjusts the cleaning position and angle according to the feedback information of the visual measurement component 52, so that the laser cleaning mechanism 3 can clean the two ends of the brake beam 100 more accurately and thoroughly. The centering assembly is used to keep the brake beam 100 aligned during transportation, providing a good initial positioning for subsequent inspection and cleaning operations; the laser cleaning machine 3 is symmetrically and positionally adjustable on both sides of the cleaning area, so that the cleaning of the two ends of the brake beam 100 is more flexible; the shape of the brake beam 100 to be cleaned can be inspected by the detection mechanism 4, and the detection mechanism 4 needs to detect the shape of the brake beam including: the total length of the brake beam 100, the distance between the centers of the left and right support pads of the brake beam 100, and the offset of the left and right support pads relative to the center column of the brake beam 100, where the support pads are the supporting parts on both sides of the brake beam, which play the role of supporting and fixing the brake components; confirm whether the brake beam 100 meets the requirements of the following requirements: The brake beam 100 that does not meet the cleaning requirements can be screened out in time to avoid ineffective cleaning and waste of resources. Through the lifting component 51 and the visual measurement component 52 of the auxiliary cleaning mechanism 5, the lifting component 51 can lift the brake beam 100 to the working height of the laser cleaning mechanism 3 to ensure that the laser cleaning equipment can fully contact the area to be cleaned, effectively avoiding the cleaning blind area caused by the height deviation of the brake beam 100. The visual measurement component 52 can measure the specific positions of the two ends of the brake beam 100 in real time, and provide position information for the laser cleaning mechanism 3 to adjust the working angle and position of the laser cleaning mechanism 3 to avoid incomplete cleaning of the laser equipment due to incorrect position. Therefore, the brake beam laser cleaning system realizes automation from loading to cleaning and then to unloading. Through the early screening of the detection component, the mutual cooperation and flexible adjustment of the lifting component 51, the visual measurement component 52 and the laser cleaning mechanism 3, the laser cleaning equipment is not limited by space when approaching the root of the brake beam 100, and can accurately locate the part to be cleaned, thereby improving the cleaning efficiency and accuracy.

[0037] like Figure 1As shown, in order to further improve the cleaning efficiency, in some embodiments, the conveying mechanism 1 includes a conveyor line 11 and a pallet 12, the pallet 12 is placed on the conveyor line 11, and each pallet 12 is provided with a plurality of brake beam mounting positions 13, the plurality of brake beam mounting positions 13 are spaced apart along the length direction of the conveyor line 11, and the brake beams 100 are sequentially placed on the brake beam mounting positions 13 of the pallet 12; wherein, the conveyor line 11 serves as the main transportation channel for the entire cleaning process, and drives the pallet 12 to move along a set path to ensure that the brake beams 100 can pass through the cleaning process in sequence; by evenly distributing the plurality of brake beam mounting positions 13 on the pallet 12, each pallet 12 can simultaneously accommodate a plurality of brake beams 100 and keep them spaced apart from each other, thereby increasing the loading capacity of a single conveyance, reducing the number of round trips of the pallet 12, and improving the efficiency of the production line; further, the plurality of brake beam mounting positions 13 are evenly spaced apart along the length direction of the conveyor line 11, so that the position of each brake beam 100 can be relatively fixed and the spacing can be consistent, which is convenient for accurate alignment of the jacking assembly 51 and reduces the complexity of mechanical positioning.

[0038] like Figure 2 As shown, in order to prevent the displacement of the pallet 12 during the cleaning process, in some embodiments, the auxiliary cleaning mechanism 5 also includes a limit assembly 53, which is movably arranged on the cleaning area along the height direction of the conveyor line 11 to limit the movement of the pallet 12 after it conveys the brake beam 100 to the position above the lifting assembly 51; wherein, the limit assembly 53 can limit the displacement of the pallet 12 during the cleaning process, ensuring that the pallet 12 is always in the ideal position without moving after conveying the brake beam 100 to the position above the lifting assembly 51. Specifically, the limit assembly 53 includes a limit drive and a limit block. The limit block can be installed in a liftable manner on the cleaning area to block the movement of the pallet 12. The limit drive is set at the bottom of the conveyor line 11, and the output end of the limit drive is connected to the limit block to drive the lifting operation of the limit block. When the pallet 12 moves to the cleaning area and the brake beam 100 is located above the jacking assembly 51, the limit block rises to stop the pallet 12 from moving forward, and the brake beam 100 on the pallet 12 is fixed above the jacking assembly 51, so that the jacking assembly 51 can lift the brake beam 100 with all its heart. After the brake beam 100 is cleaned, the cleaned brake beam 100 is replaced on the pallet 12, and the limit block immediately drops to allow the pallet 12 to continue to move to the lower material area.

[0039] Continue as Figure 2As shown, in order to accurately control the displacement of the tray 12, in some embodiments, a plurality of limit assemblies 53 are provided, and the plurality of limit assemblies 53 are spaced apart along the length direction of the conveyor line 11; wherein, when a plurality of brake beams 100 are placed on the tray 12, when the first brake beam 100 is cleaned, the first limit assemblies 53 close to the tray 12 are raised to limit the movement of the tray 12, and after the first brake beam 100 is cleaned, the first limit assemblies 53 are lowered to allow the tray 12 to move forward smoothly, and after ensuring that the second brake beam 100 accurately reaches the top of the lifting assembly 51, the limit assemblies 53 at the corresponding position are raised to block the movement of the tray 12, and the cycle is repeated. Furthermore, the spacing between adjacent limit assemblies 53 can be kept consistent with the spacing between adjacent brake beam mounting positions 13, so that the displacement of the tray 12 can be accurately controlled, so that the mounting position of each brake beam 100 matches the cleaning process, and each brake beam 100 can be orderly connected to the laser cleaning area and cleaned in time, thereby optimizing the entire cleaning process and improving the work efficiency of the production line. In other embodiments, the limit assembly 53 can also be disposed below the detection mechanism 4 or below the centering mechanism 2 to help accurately position the tray 12 , reduce misoperation and unnecessary displacement of the tray 12 , and thereby ensure the accuracy of the position of the brake beam 100 .

[0040] like Figure 3 As shown, in order to improve the accuracy of the centering mechanism 2, in some embodiments, the centering mechanism 2 includes a supporting column 21, a centering drive member 22 and a push plate 23. The supporting columns 21 are symmetrically arranged on both sides of the loading area along the height direction of the conveyor line 11. The distance between the two symmetrically arranged supporting columns 21 is greater than the length of the brake beam 100. The centering drive member 22 is arranged at the top of the supporting column 21. The output end of the centering drive member 22 is connected to the push plate 23. The centering drive member 22 can drive the push plate 23 to move toward or away from the end of the brake beam 100; wherein, the centering mechanism 2 can realize automatic centering operation through the centering drive member 22 and the push plate 23, and accurately position the brake beam 100 so that its middle position is in On the central axis of the conveyor line 11, the detection mechanism 4 can perform morphological detection according to a fixed reference position, and can also ensure that the brake beam 100 is in a good centered state before entering the cleaning process, which is helpful for the accuracy of the subsequent laser cleaning process and avoids uneven or offset cleaning; by supporting columns 21 symmetrically arranged on both sides of the feeding area of ​​the conveyor line 11 and the spacing is greater than the length of the brake beam 100, a stable support structure is formed, and at the same time, it can ensure that the brake beam 100 passes smoothly; by the centering drive member 22 controlling the movement of the push plate 23 close to or away from the end of the brake beam 100, the position of the brake beam 100 can be adjusted, and the centering mechanism 2 can be flexibly adjusted to adapt to brake beams 100 of different lengths and shapes. It can be understood that the centering drive member 22 can be, but is not limited to, a DC drive motor, which is not specifically limited here.

The brake beams 100 that exceed the size range can be eliminated without cleaning, thereby improving the consistency and efficiency of the overall process.

[0042] like Figure 4 As shown, in order to further improve the detection accuracy, in some embodiments, the visual detection component 41 includes a guide rail 411, a deceleration drive component 412, a mechanical arm 413 and an imaging component 414. The guide rail 411 is arranged on the single-axis truss 42 along the width direction of the conveyor line 11. One end of the mechanical arm 413 is slidably connected to the guide rail 411, and the other end of the mechanical arm 413 is connected to the imaging component 414. The output end of the deceleration drive component 412 is connected to the mechanical arm 413 to drive the mechanical arm 413 to drive the imaging component 414 to move along the guide rail 411. The mechanical arm 413 can drive the imaging component 414 to rotate; wherein the mechanical arm 413 slides along the guide rail 411 to cover the entire area in the width direction of the conveyor line 11, ensuring The detection range is comprehensive and has no blind spots. In addition, the mechanical arm 413 can drive the imaging component 414 to rotate, and can perform multi-directional scanning of the brake beam 100, so as to realize multi-angle detection, and realize more detailed detection of details such as the edge area and surface defects of the brake beam 100, thereby enhancing the flexibility and accuracy of the detection. The deceleration drive component 412 provides a stable power output to ensure that the mechanical arm 413 moves smoothly and accurately, which helps the imaging component 414 to collect high-quality images and reduce the impact of vibration on the imaging quality. The imaging component 414 can capture images in real time during the sliding and rotation of the mechanical arm 413 to realize dynamic detection, which is suitable for scenes where the production line is continuously running, and ensures that the detection efficiency is synchronized with the production rhythm. It is understandable that the imaging component 414 can use a high-resolution camera or a CMOS camera according to actual needs, and no specific limitation is made here.

When the brake beam 100 is transported to the top of the lifting assembly 51, the lifting assembly 51 is started, and the brake beam 100 is supported by the support member 513 to move to the working height position of the laser cleaning mechanism 3, reducing the adjustment time, so that the cleaning mechanism can start working quickly, thereby improving production efficiency. Among them, the lifting drive member 512 can be but not limited to a lifting cylinder, which is not specifically limited here. In other embodiments, a buffer member, such as a silicone gasket, is provided on the side of the support member 513 facing the brake beam 100, which is not specifically limited; the buffer member is made of soft material, which can reduce the hard collision when the support member 513 is in direct contact with the brake beam 100, and prevent the surface of the brake beam 100 from being damaged due to pressure or friction.

[0046] The following is the operating process of the brake beam laser cleaning system:

[0047] First, the brake beam 100 is placed on the conveying mechanism 1, and the conveying mechanism 1 drives the brake beam 100 to move along the directions of the loading area, the cleaning area and the unloading area;

[0048] Next, the brake beam 100 is transported to the positions of the centering mechanism 2 on both sides of the loading area, and the centering mechanism 2 performs centering correction on the brake beam 100 along the central axis of the conveying mechanism 1;

[0049] Afterwards, the brake beam 100 is transported to the position of the detection mechanism 4, and the detection mechanism 4 detects the shape of the brake beam 100, removes the brake beam 100 that does not meet the cleaning requirements, and transports the brake beam 100 that meets the cleaning requirements to the cleaning area;

[0050] Secondly, the brake beam 100 is transported to the top of the lifting assembly 51 in the cleaning area. The lifting assembly 51 lifts the brake beam 100 to the working height position of the laser cleaning mechanism 3. The visual measurement assembly 52 measures the positions of the two ends of the brake beam 100. After receiving the position information, the laser cleaning mechanism 3 adjusts the cleaning position and angle to clean the two ends of the brake beam 100.

[0051] Finally, the lifting assembly 51 places the brake beam 100 back on the conveying mechanism 1 , and the conveying mechanism 1 conveys the cleaned brake beam 100 to the unloading area.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
