[0030] Furthermore, the technical features of the various embodiments of the present invention described below can be combined with each other, as long as they do not contradict each other.

[0031] The wide-width laser rust removal apparatus shown in Figures 1-2 comprises a rust removal device and a reversing device. The rust removal device includes a cleaning table 2 suitable for placing workpieces and a rust removal assembly 3 provided above the cleaning table 2 via a three-axis drive member. The cleaning table 2 is provided with a first transport member suitable for transporting workpieces, and the rust removal assembly 3 includes a laser device and a positive pressure lens protection structure connected to the laser device. The reversing device is provided at one end of the cleaning table 2 and includes a reversing table 4 and a reversing drive member suitable for rotating the reversing table 4. The reversing table 4 is provided with a second transport member 5 suitable for transporting workpieces.

[0032] This wide-width laser rust removal system uses a laser device to remove rust and clean the workpiece (i.e., steel plate) on the cleaning table 2. The rust removal assembly 3 is mounted on a three-axis drive member, allowing the laser device to move in multiple directions for rust removal, ensuring thorough rust removal and cleaning of the steel plate, thus guaranteeing a rust removal effect. The positive pressure lens protection structure ensures stability during focused rust removal of the laser device and improves rust removal and cleaning efficiency. The first transport member allows a steel plate that has been cleaned on one side to be transported to the reversing table 4 of the reversing device located at one end of the cleaning table 2, eliminating the need for manual carrying or movement. The reversing drive member drives the reversing table 4 to reverse, allowing the steel plate transported on the reversing table 4 to be reversed from the cleaned side to the uncleaned side. Furthermore, the second transport member transports the reversed steel plate to the washing table 2 to perform rust removal and washing on the uncleaned side. This eliminates the need to manually reverse or transport the workpiece, reducing the difficulty and workload of manual operation while ensuring rust removal efficiency and quality, improving the overall rust removal efficiency and quality of the workplace, and maximizing the safety of the operator.

[0033] In this embodiment, the three-axis drive member comprises guide rail brackets 6 provided on opposing sides of the washing table 2, two X-axis guide rails 7 attached to the two guide rail brackets 6 respectively, a Y-axis guide rail 8 movably connected to the two X-axis guide rails 7, and a connecting arm 10 movably connected to the Y-axis guide rail 8. The bottom of the connecting arm 10 is provided with a Z-axis guide rod 9 and a Z-axis drive member suitable for driving the Z-axis guide rod 9 up and down to move it closer to or further away from the washing table 2. The rust removal assembly 3 is attached to the Z-axis guide rod 9. In this way, the rust removal effect of the rust removal assembly 3 can be ensured at any point on the flat surface of the steel plate, and the up and down function of the Z-axis guide rod 9 allows the rust removal assembly 3 to be adapted for rust removal of steel plates of various thicknesses and to steel plate surfaces with uneven structures.

[0034] In this embodiment, a conveying device is further provided that is connected between the rust removal device and the inversion device. The conveying device includes a conveying table, and a third conveying member is provided on the conveying table. The first conveying member, the second conveying member 5, and the third conveying member are all at the same height. In this way, stability during steel plate conveying is ensured, the conveying effect is avoided due to an uneven conveying path during the transport of the steel plate, and damage to the steel plate in a conveying path with height differences can be avoided.

[0035] Specifically, the first conveying member, the second conveying member 5, and the third conveying member are all multiple rollers provided at equal intervals. By using rollers as the conveying structure in this way, the efficiency of steel plate conveying can be improved, and because the roller structure has higher structural strength than other conveying structures, it can withstand the load on the steel plate and ensure the service life of the conveying structure.

[0036] In this embodiment, the rust removal assembly 3 is equipped with a dust cover fixed to the Z-axis guide rod 9. The dust cover has a semi-sealed structure, and both the laser device and the positive pressure lens protection structure are located inside the dust cover. By arranging a semi-sealed dust cover and placing both the laser device and the positive pressure lens protection structure inside the dust cover, it is possible to ensure that the laser device and the positive pressure lens protection structure operate efficiently and stably, while also achieving environmental friendliness.

[0037] Specifically, the rust removal assembly 3 further includes a dust removal device installed inside the dust cover. This dust removal device allows for rust removal of the steel plate while simultaneously suctioning away contaminants resulting from the rust removal process, ensuring that there is no contamination from laser rust removal.

[0038] In this embodiment, the reversing table 4 has a frame structure with both ends extending through it, and rollers are provided on both the upper and lower inner walls of the reversing table 4. In this way, by providing rollers on both the upper and lower side walls of the frame structure of the reversing table 4, steel plates can be easily transported regardless of which side the reversing table 4 is reversed to.

[0039] Specifically, the inversion table 4 is provided with two trays suitable for placing steel plates, and the outside of the inversion table 4 is provided with two clamping drive members suitable for driving the two trays to move closer together or further apart from each other. In this way, by controlling the trays with the clamping drive members to move them closer together, the two trays clamp the steel plate placed on the trays, ensuring that the steel plate is fixed in place and facilitating subsequent inversion of the steel plate.

[0040] Specifically, both clamping drive members are equipped with a magnetic adsorption structure suitable for adsorbing trays. In this way, the trays are firmly adsorbed by the magnetic adsorption structure, and the clamping drive members control the magnetic adsorption structure to bring the trays closer together, so that the two trays clamp the steel plate placed on the trays, ensuring that the steel plate is fixed in place, facilitating the subsequent inversion of the steel plate, and when the inversion is complete, the adsorption of the tray located on the lower side in the inversion table 4 is released, making it easy for the tray to move to the next station with the steel plate on it.

[0041] In this embodiment, a restricting structure is provided at one end of the reversing table 4 that is separated from the rust removal equipment. In this way, the restricting structure restricts the steel plates on the reversing table 4, preventing the steel plates from overhanging or falling off the reversing table 4 during steel plate transport.

[0042] In this embodiment, the rust removal equipment is electrically connected to the cleaning host 11. Further comprising an industrial console 1 electrically connected to the cleaning host 11, the inversion equipment, and the conveying equipment, the industrial console 1 controls the rust removal / cleaning work, conveying work, and inversion work, thereby improving operational accuracy. There is no need to determine the focus height based on human experience, and the laser head does not have the problem of accumulation of errors in the focus point height due to long-term continuous adjustment. This effectively reduces equipment maintenance and correction time, enabling long-term, high-quality, and highly efficient rust removal, and significantly improving the rust removal efficiency and intelligence level of the entire process.

[0043] The principle of operation is as follows: When removing rust from a steel plate, the steel plate is placed on the washing table 2 using one tray (at this time, the other tray is positioned on the upper side of the inversion table 4 under the magnetic attraction of the magnetic attraction structure). After the laser head completes the rust removal process on the side of the steel plate that is separated from the tray, the tray moves the steel plate along the rollers on the washing table 2 onto the rollers of the transport equipment, and then onto the lower rollers in the inversion table 4. After being transported to the predetermined position, the magnetic attraction structure located on the lower side of the inversion table 4 attracts and fixes the tray on which the steel plate is placed, and the upper clamping drive member of the inversion table 4 controls the upper magnetic attraction structure to lower the corresponding tray, so that the two trays clamp and fix the steel plate. Furthermore, the reversing drive member is turned on to reverse the reversing table 4 by 180° and invert the steel plate. The tray located on the upper side of the reversing table 4 after reversal is then controlled to separate it from the steel plate, and the magnetic suction structure located on the lower side of the reversing table 4 after reversal is released from its suction hold. Finally, the rollers on the lower side of the washing table 2 gradually transport the tray and the steel plate on the tray to the washing table 2, and the inverted steel plate is washed on the other side.

[0044] As described above, this wide-width laser rust removal device uses a laser device to remove rust and clean the workpiece (i.e., steel plate) on the cleaning table 2. The rust removal assembly 3 is mounted on a three-axis drive member, allowing the laser device to move in multiple directions to remove rust, ensuring that the rust removal equipment thoroughly removes rust and cleans the steel plate, thus ensuring a rust removal effect. The positive pressure lens protection structure ensures the stability of the laser device during focused rust removal and improves rust removal and cleaning efficiency. The first transport member allows the steel plate, which has been cleaned on one side, to be transported onto the inversion table 4 of the inversion device located at one end of the cleaning table 2, eliminating the need for manual carrying or movement. The reversing drive member drives the reversing table 4 to reverse, allowing the steel plate transported on the reversing table 4 to be reversed from the cleaned side to the uncleaned side. Furthermore, the second transport member transports the reversed steel plate to the washing table 2 to perform rust removal and washing on the uncleaned side. This eliminates the need to manually reverse or transport the workpiece, reducing the difficulty and workload of manual operation while ensuring rust removal efficiency and quality, improving the overall rust removal efficiency and quality of the workplace, and maximizing the safety of the operator.

[0045] As is clear, the above embodiments are merely examples given for illustrative purposes and do not limit the embodiments. Those skilled in the art can make various other modifications and changes based on the above description. It is neither necessary nor possible to list all embodiments here.
