Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a laser cleaning device. Background Technology

[0002] Laser cleaning is a non-contact cleaning technology that utilizes the interaction between a high-energy laser beam and contaminants to selectively remove surface contaminants through photothermal or photomechanical effects. Its core advantage lies in the ability to precisely control the laser wavelength, energy density, and pulse frequency, causing contaminants to evaporate, vaporize, or peel off instantaneously, while the substrate material remains almost unaffected.

[0003] In addition, laser cleaning heads can efficiently and accurately clean curved workpieces. Through photothermal effects, contaminants are instantly vaporized or peeled off without damaging the substrate. When laser cleaning a workpiece, the workpiece is first placed on the operating table. The top of the workpiece is cleaned by a laser cleaning head that moves continuously on one side. After cleaning the top of the workpiece, the workpiece can be rotated so that the other side of the workpiece faces the laser cleaning head. Then, the other side of the workpiece is cleaned by the laser cleaning head. Since workpieces generally have multiple sides, this type of laser cleaning equipment needs to clean each side of the workpiece one by one, which reduces cleaning efficiency to some extent.

[0004] Therefore, it is necessary to provide a new laser cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] In the specific implementation process, such as Figures 1-5As shown, the system includes an operating table 1, on which an adjustment device is provided. An adjustment plate 2 is mounted on the adjustment device. The adjustment device is used to drive the adjustment plate 2 to move on the xOy plane. The xOy plane is the plane formed by the X-axis, Y-axis and origin O in the mathematical coordinate system. A lifting device is rotatably connected to the adjustment plate 2. A mounting plate 3 is fixed on the lifting end of the lifting device. Two adjustable mounting brackets 4 are slidably arranged on the mounting plate 3. Laser cleaning heads 5 are fixedly installed on the opposite side walls of the two mounting brackets 4. Two adjustable support members are installed on the operating table 1. The support members can extend and retract along the Z-axis direction, which is perpendicular to the xOy plane. A rotating member is provided on the operating table 1 between the two support members. A telescopic member is installed on the rotating member. A top plate 6 is installed on the telescopic member.

[0021] In use, the distance between the two laser cleaning heads 5 is adjusted according to the workpiece size. The workpiece to be cleaned is placed on the two supports. The position of the adjusting plate 2 is moved by the adjusting device so that the two laser cleaning heads 5 are located on the upper and lower sides of the workpiece, respectively. During cleaning, the position of the two mounting brackets 4 is adjusted by the adjusting device, and the two laser cleaning heads 5 clean the top and bottom of the workpiece, respectively. Then, the laser heads are moved away from the workpiece, and the lifting device is rotated so that the two laser cleaning heads 5 are on the same horizontal plane. The distance between the two mounting brackets 4 is adjusted, and the laser cleaning heads 5 are moved towards the workpiece. The two laser cleaning heads 5 are located on the longitudinal sides of the workpiece, respectively. The lifting device can drive the laser cleaning heads 5 to different heights on the side of the workpiece, and the adjusting device can make the laser cleaning heads 5 located at different lateral positions on the side of the workpiece, thereby achieving cleaning of the side of the workpiece. Finally, the telescopic component drives the top plate 6 to lift the workpiece, and the rotating component drives the workpiece to rotate. After rotating a certain angle, the top plate 6 drives the workpiece back to the two supports, thus facilitating cleaning of different sides of the workpiece.

[0022] The adjustment device includes a longitudinal plate 7, a transverse plate 8, a longitudinal electric cylinder 9, and a transverse electric cylinder 10. The longitudinal plate 7 is fixed on the operating table 1, the longitudinal electric cylinder 9 is fixed on the longitudinal plate 7, the transverse plate 8 is slidably disposed on the longitudinal plate 7, and the telescopic end of the longitudinal electric cylinder 9 is fixedly connected to the transverse plate 8. A guide rail 11 is fixed on the transverse plate 8, and a sliding plate 12 is slidably disposed on the guide rail 11. One end of the sliding plate 12 is fixed on the adjustment plate 2. The transverse electric cylinder 10 is fixed on the transverse plate 8, and the telescopic end of the transverse electric cylinder 10 is fixed on the adjustment plate 2. The longitudinal electric cylinder 9 drives the transverse plate 8 to move longitudinally, thereby realizing the longitudinal movement of the laser cleaning head 5. The transverse electric cylinder 10 drives the adjustment plate 2 to move laterally, thereby realizing the lateral movement of the laser cleaning head 5.

[0023] The lifting device includes a lifting frame 13, a lifting cylinder 14, and a lifting plate 15. The lifting frame 13 is rotatably connected to the adjusting plate 2. The lifting plate 15 is slidably disposed on the lifting frame 13. "Slidably disposed" can be understood as two or more guide rods 26 being fixed on the lifting frame 13. The guide rods 26 movably pass through the lifting plate 15, and the lifting plate 15 is fixedly connected to the mounting plate 3. The lifting cylinder 14 is fixed on the lifting frame 13, and the telescopic end of the lifting cylinder 14 is fixed to the lifting plate 15. The lifting plate 15 is driven to slide on the lifting frame 13 by the lifting cylinder 14, which facilitates the cleaning of the side of the workpiece by the laser cleaning head 5.

[0024] The phrase "a lifting device is rotatably connected to the adjusting plate 2" in this application can be understood as a rotatable connection between the lifting frame 13 and the adjusting plate 2, for example, the two are connected by bearings. A second motor 25 is fixedly installed on the adjusting plate 2, and the output end of the second motor 25 is fixed on the lifting frame 13. This structure allows the second motor 25 to rotate only the lifting frame 13 without supporting the weight of the lifting frame 13, thereby improving the service life of the second motor 25.

[0025] The mounting plate 3 has placement slots 16 at both ends, and an adjusting electric cylinder 17 is fixed in each of the two placement slots 16. The two mounting brackets 4 are slidably disposed in the two placement slots 16 respectively. The telescopic ends of the two adjusting electric cylinders 17 are fixed on the two mounting brackets 4 respectively. The adjusting electric cylinders 17 drive the mounting brackets 4 to move in the placement slots 16, thereby realizing the adjustment of the distance between the laser cleaning heads 5 on the two mounting brackets 4.

[0026] The operating table 1 has multiple limiting grooves 18. The support includes a base plate 19, a sleeve plate 20, and a movable plate 21. The base plate 19 is connected to the limiting grooves 18 by bolts. The sleeve plate 20 is fixed to the top of the base plate 19. The movable plate 21 is slidably disposed within the sleeve plate 20. The sleeve plate 20 and the movable plate 21 are positioned by bolts. This can be understood as the sleeve plate 20 being threadedly connected to the bolts. When the movable plate 21 moves to a suitable position, the bolts can be rotated, causing the end of the bolts to abut against the movable plate 21, thus enabling the movable plate 21 to move. The locking mechanism of the movable plate 21 can also be achieved by having multiple through holes from top to bottom on the movable plate 21. When the movable plate 21 moves to a certain position, the bolt can be rotated so that the end of the bolt moves into the through hole of the movable plate 21, thereby locking the movable plate 21. By setting multiple limiting grooves 18, the base plate 19 can be installed in a certain limiting groove 18 by bolts, which facilitates the installation of the support on the operating table 1. According to the usage requirements, the base plate 19 can be installed in different limiting grooves 18 to adjust the distance between the two support members.

[0027] The rotating component includes a bracket 22 and a first motor 23. The bracket 22 is fixed in the side groove of the operating table 1, and the first motor 23 is fixed to the bottom wall of the side groove. A rotating rod is rotatably connected to the bracket 22, and the output end of the first motor 23 is fixedly connected to the rotating rod. The telescopic component is a movable electric cylinder 24. The bottom end of the movable electric cylinder 24 is fixed to the rotating rod, and the telescopic end of the movable electric cylinder 24 extends to the outside of the side groove and is fixedly connected to the top plate 6. The first motor 23 drives the telescopic component and the top plate 6 on it to rotate, thereby rotating the workpiece. The movable electric cylinder 24 drives the top plate 6 to extend and retract, thereby lifting and lowering the workpiece.

[0028] It also includes an analysis module, a control module, and two camera acquisition modules (not shown in the figure). The two camera acquisition modules are respectively installed on two mounting brackets 4 near the laser cleaning head 5. The analysis module, control module, and two camera acquisition modules are electrically connected. After the workpiece is cleaned, the camera acquisition modules take images of the workpiece surface (high resolution + uniform light source required). After taking the images, the data is transmitted to the analysis module. If the residual rate is > a threshold (e.g., 3%), "repeated cleaning" is triggered. At this time, the control module controls the laser cleaning head 5 to move to the corresponding position for secondary cleaning. If it is ≤ a threshold, the process ends.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
