Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, and more specifically, to a wide-width laser derusting device.

Background Art

[0002] When a steel structure factory performs derusting of component plates, generally, it is necessary to perform derusting and cleaning of the steel plate surface manually or by using large equipment such as a shot blasting machine, so as to ensure that the appearance and roughness meet the quality requirements and facilitate subsequent further painting treatment. However, due to various factors such as the working load of workers and the resource consumption, it is disadvantageous for the further energy saving and efficiency improvement of the factory. In addition, when performing derusting treatment on multiple surfaces of the steel plate, it is necessary for the operator to manually invert it. When the weight of the steel plate is large, manual inversion is dangerous and the safety of the operator cannot be guaranteed.

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

[0031] The wide-width laser derusting device shown in FIGS. 1 to 2 includes a derusting device and a reversing device. Here, the derusting device includes a cleaning table 2 suitable for placing a workpiece, and a derusting 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 the workpiece, and the derusting assembly 3 has 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 rotationally driving the reversing table 4. The reversing table 4 is provided with a second transport member 5 suitable for transporting the workpiece.

[0032] Such a wide-width laser derusting device performs derusting and cleaning on a workpiece (i.e., a steel plate) on the cleaning table 2 by means of a laser device. The derusting assembly 3 is provided on a three-axis drive member, so that the laser device can move in multiple directions for derusting, ensuring that the derusting equipment thoroughly derusts and cleans the steel plate, and the derusting effect can be ensured. The provision of a positive pressure lens protection structure can ensure the stability of the laser device during focusing derusting and improve the derusting and cleaning efficiency. The provision of the first conveying member enables the steel plate that has been cleaned on one side to be conveyed onto the reversing table 4 of the reversing device at one end of the cleaning table 2, eliminating the need for manual handling or movement. By driving the reversing table 4 to reverse by means of a reversing drive member, the steel plate conveyed onto the reversing table 4 can be reversed from the cleaned surface to the uncleaned surface. Furthermore, the reversed steel plate can be conveyed onto the cleaning table 2 by means of the second conveying member for derusting and cleaning of the uncleaned surface. Without the need for manual reversal or conveyance of the workpiece, on the premise of ensuring derusting efficiency and quality, the difficulty of manual operation and the workload are reduced, the derusting efficiency and quality of the entire workplace are improved, and the safety of the operator's body is maximally ensured.

[0033] In this embodiment, the three-axis drive member includes guide rail brackets 6 provided on both opposite sides of the cleaning table 2, two X-axis guide rails 7 respectively attached to the two guide rail brackets 6, 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. At the bottom of the connecting arm 10, a Z-axis guide rod 9 and a Z-axis drive member suitable for driving the Z-axis guide rod 9 to move up and down to approach or separate from the cleaning table 2 are provided. The derusting assembly 3 is attached to the Z-axis guide rod 9. In this way, the derusting effect of the derusting assembly 3 at any part of the steel plate plane can be ensured. Moreover, due to the lifting function of the Z-axis guide rod 9, the derusting assembly 3 can adapt to derusting of steel plates of various thicknesses and also to a steel plate plane with an uneven structure.

[0034] In this embodiment, a conveying device connected between the rust removal device and the inversion device is further provided. The conveying device includes a conveying table, a third conveying member is provided on the conveying table, and the first conveying member, the second conveying member 5, and the third conveying member are all at the same height. In this way, the stability during steel plate conveyance can be ensured, the conveyance effect can be prevented from being impaired by an uneven conveyance path during the conveyance of the steel plate, and damage to the steel plate on a conveyance 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 a plurality of rollers provided at equal intervals. In this way, by using the rollers as the conveying structure, the steel plate conveying efficiency can be improved. Also, since the roller structure has higher structural strength than other conveying structures, it can adapt to the load on the steel plate and ensure the service life of the conveying structure.

[0036] In this embodiment, the rust removal assembly 3 includes a dust-proof cover fixedly attached to the Z-axis guide rod 9. The dust-proof cover has a semi-closed structure, and both the laser device and the positive pressure lens protection structure are located inside the dust-proof cover. In this way, by arranging the semi-closed dust-proof cover and providing both the laser device and the positive pressure lens protection structure inside the dust-proof cover, it can be ensured that the laser device and the positive pressure lens protection structure operate efficiently and stably, and environmental friendliness can be achieved.

[0037] Specifically, the rust removal assembly 3 further includes a dust removal device installed inside the dust-proof cover. In this way, by providing the dust removal device, the rust removal operation of the steel plate can be performed, contaminants generated by rust removal can be sucked by the dust removal device, and it can be ensured that there is no pollution caused by laser rust removal.

[0038] In this embodiment, the inversion table 4 has a frame structure with both ends penetrating, and rollers are provided on both the upper and lower inner walls of the inversion table 4. In this way, by providing rollers on both the upper and lower side walls of the frame-structured inversion table 4, the steel plate can be easily conveyed regardless of which side the inversion table 4 is inverted to.

[0039] Specifically, two trays suitable for placing steel plates are provided inside the inversion table 4, and two clamping drive members suitable for driving the two trays to approach or separate from each other are provided outside the inversion table 4. In this way, by controlling the trays with the clamping drive members to approach each other, the two trays clamp the steel plate placed on the trays, ensuring the fixation of the steel plate and facilitating subsequent inversion of the steel plate.

[0040] Specifically, both of the two clamping drive members are provided with a magnetic adsorption structure suitable for adsorbing the trays. In this way, the trays are firmly adsorbed by the magnetic adsorption structure, and by controlling the magnetic adsorption structure with the clamping drive members to make the trays approach each other, the two trays clamp the steel plate placed on the trays, ensuring the fixation of the steel plate and facilitating subsequent inversion of the steel plate. When the inversion is completed, by releasing the adsorption of the tray located on the lower side inside the inversion table 4, it is easy for the tray to carry the steel plate and move to the next station.

[0041] In this embodiment, a restricting structure is provided at one end of the inversion table 4 that is separated from the rust removal device. In this way, the steel plate on the inversion table 4 can be restricted by the restricting structure, avoiding the steel plate from protruding or falling off the inversion table 4 during steel plate conveyance.

[0042] In this embodiment, the rust removal device is electrically connected to the cleaning host 11. The industrial console 1 electrically connected to the cleaning host 11, the inversion device, and the conveying device is further provided. By controlling the rust removal / cleaning operation, the conveying operation, and the inversion operation with the industrial console 1, the operation accuracy can be improved, there is no need to judge the focus height by oneself based on manual experience, there is no problem of error accumulation in the height of the focus point due to long-term continuous adjustment of the laser head, the maintenance and correction time of the device can be effectively reduced, long-term, high-quality, and high-efficiency rust removal can be realized, and the rust removal efficiency and the intelligent level of the whole process can be greatly improved.

[0043] The principle of operation is as follows. When descaling a steel plate, the steel plate is placed on the cleaning table 2 by a tray (at this time, the other tray is located above in the reversing table 4 under the adsorption action of the magnetic adsorption structure). After the descaling operation on the side of the steel plate away from the tray by the laser head is completed, the tray moves the steel plate along the rollers on the cleaning table 2 onto the rollers of the conveying device and further onto the lower rollers in the reversing table 4. After being conveyed to a predetermined position, the magnetic adsorption structure located below the reversing table 4 adsorbs and fixes the tray with the steel plate on it, and further controls the upper magnetic adsorption structure by the clamping drive member above the reversing table 4 to lower the corresponding tray, so that the two trays clamp and fix the steel plate. Further, turn on the reversing drive member to reverse the reversing table 4 by 180° to reverse the steel plate, and further control the tray located above in the reversing table 4 after reversal to separate from the steel plate, release the adsorption and fixation of the tray by the magnetic adsorption structure located below in the reversing table 4 after reversal, and further gradually convey the tray located above it and the steel plate on the tray to the cleaning table 2 by the lower rollers in the cleaning table 2 to clean the steel plate reversed to the other side.

[0044] As described above, this wide-width laser derusting device performs derusting and cleaning on the workpiece (i.e., steel plate) on the cleaning table 2 by means of a laser device. The derusting assembly 3 is provided on a three-axis drive member, so that the laser device can move in multiple directions for derusting, ensuring that the derusting equipment thoroughly derusts and cleans the steel plate and ensuring the derusting effect. The provision of a positive pressure lens protection structure ensures the stability of the laser device during focusing and derusting, and can improve the derusting and cleaning efficiency. The provision of the first conveying member enables the steel plate that has been cleaned on one side to be conveyed onto the reversing table 4 of the reversing device at one end of the cleaning table 2, eliminating the need for manual handling or movement. By driving the reversing table 4 to reverse by means of a reversing drive member, the steel plate conveyed onto the reversing table 4 can be reversed from the cleaned surface to the uncleaned surface. Further, the steel plate after reversal is conveyed onto the cleaning table 2 by means of the second conveying member for derusting and cleaning of the uncleaned surface, eliminating the need for manual reversal or conveyance of the workpiece. On the premise of ensuring the derusting efficiency and quality, the difficulty of manual operation and the workload are reduced, the derusting efficiency and quality of the entire workplace are improved, and the safety of the operator's body is maximally ensured.
