Description

Technical Field

[0001] The invention relates to the technical field of laser cleaning, in particular to an online laser rust removal and cleaning device and system. Background Art

[0002] With the development of science and technology, people are paying more and more attention to the quality of life and the awareness of environmental protection is getting stronger. Traditional cleaning methods, such as mechanical cleaning, chemical cleaning and ultrasonic cleaning, can no longer meet people's needs. People are beginning to pursue new cleaning methods that do not harm health or pollute the environment. Therefore, laser cleaning machines came into being.

[0003] The so-called laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece, causing the dirt, rust or coating on the surface to evaporate or peel off instantly, and quickly and effectively remove the attachments or coatings on the surface of the cleaning object, thereby achieving a clean process. Laser cleaning is a new and efficient environmentally friendly cleaning technology, and is a new technology based on the interaction effect between laser and matter. Unlike traditional mechanical cleaning methods, chemical cleaning methods and ultrasonic cleaning methods (wet cleaning processes), it does not require any CFC organic solvents that damage the ozone layer, is pollution-free, noise-free, and harmless to the human body and the environment. It is a "green" cleaning technology that is gradually replacing traditional cleaning processes in many fields.

[0004] The principle of laser rust removal, in simple terms, is to use the 1064nm wavelength laser generated by the Nd:YAG solid laser, which is specially used for cleaning, to produce high-frequency vibrations (up to 1,000 vibrations per second) to break the rust layer; the instantaneous high temperature generated by the laser is used to peel the rust layer off the surface of the substrate, thereby achieving the purpose of rust removal. Laser cleaning will not damage the surface of the substrate, nor will it even change the physical characteristics of the substrate, so it will truly not damage the substrate. Laser rust removal uses lasers with a certain peak power and single pulse energy. When the laser contacts the work surface, it can be imagined as using small energy balls to hit it in turn. The rust will absorb energy. Due to the short action time, the rust on the surface absorbs energy and vaporizes instantly, and it cannot conduct heat downward, which will cause the surface rust to disappear instantly without damaging the workpiece. The laser is converted into a line laser with a mirror, and the processing speed is relatively fast.

[0005] At present, the commonly used is the handheld laser cleaning system, that is, the handheld laser gun, which can be widely used in non-standard and irregular paint removal, rust removal, dirt removal, and oxide skin removal. The movement trajectory of the laser scanning head is controlled by hand, and its advantages are flexible and convenient operation and mobile operation. Its disadvantages are poor accuracy, poor consistency, high labor intensity, and it is difficult to batch work, and the stability of rust removal quality is difficult to guarantee.

[0006] At present, there are also semi-automatic or fully-automatic laser cleaning systems. The motion trajectory of the laser scanning head is controlled by a manipulator / machine tool. The former uses a platform similar to a machining center to install the scanning head on a spindle driven by a servo motor to achieve semi-automatic cleaning and maintain the cleaning distance; the latter installs the optical scanning head on a motion mechanical device (such as a robot, manipulator, etc.), and the mechanical device automatically completes the preset motion trajectory. The advantages of semi-automatic or fully-automatic laser cleaning systems are high precision, large-scale operation, and low technical requirements and labor intensity for operators. However, since the workpiece to be cleaned does not move, a semi-automatic or fully-automatic laser cleaning system is required to move, but it is difficult for a semi-automatic or fully-automatic laser cleaning system to complete the movement of irregular trajectories, and the robot must be adjusted for a long time to achieve it. It is not economical to remove rust from long workpieces such as steel pipes, and the repeatability of the operation is not easy to guarantee. Summary of the invention

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. Among them, the use of adjective or adverbial modifiers "center", "clockwise" and "counterclockwise", "front" and "back", "left" and "right", "top" and "bottom", "inside" and "outside" is only to facilitate relative reference between multiple groups of terms, and does not describe any specific directional restrictions on the modified terms. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0036] like Figures 1 to 5 As shown, the present invention provides an online laser rust removal cleaning device, which can remove rust from a steel pipe 100 moving through it. The cleaning device comprises a rack 1 and a plurality of lasers 2, for example, the lasers 2 are laser guns, and a through hole 11 is axially provided in the rack 1 for the moving steel pipe 100 to pass through. Figure 1 The arrow in the figure indicates the moving direction of the steel pipe 100. Of course, the steel pipe 100 can also move in the opposite direction. The through hole 11 is not limited to a circular hole, but can also be a square hole, a trapezoidal hole, a stepped hole or other shapes, as long as the steel pipe 100 can pass through.

[0037] Multiple lasers 2 are installed on one side of the tray 1. Figure 1In the embodiment of the invention, a plurality of lasers 2 are installed on the left side of the bracket. The steel pipe 100 passes through the perforation 11 and the space inside the plurality of lasers 2 in sequence during the forward movement. The plurality of lasers 2 are arranged in an annular pattern around the steel pipe 100. Each laser 2 is tilted relative to the steel pipe 100. There is a spacing between each laser 2 and the steel pipe 100. Each laser 2 can be rotatably connected to the disc rack 1 and can swing around the connection between the laser 2 and the disc rack 1. One end of each laser 2 is a laser emitting end facing the steel pipe 100. The laser emitting end can emit a laser beam 21 for rust removal to the outer wall of the steel pipe 100. Preferably, the laser beams 21 emitted by the plurality of lasers 2 form an annular laser belt surrounding the steel pipe 100 on the outer wall of the steel pipe 100. During the forward movement of the steel pipe 100, the annular laser belt sweeps and cleans the surface of the steel pipe 100, thereby cleaning the entire outer wall of the steel pipe 100.

[0038] The other end of each laser 2 is connected to a pull rod 3, which is inclined relative to the steel pipe 100. One end of the pull rod 3 is connected to the laser 2 so that it can rotate relative to it, and the other end of the pull rod 3 can be moved radially along the disc rack 1 on the other side of the disc rack 1. By moving the other end of the pull rod 3 along the radial direction of the disc rack 1, the pull rod 3 pushes and pulls the laser 2, so that the laser 2 swings around the connection between it and the disc rack 1. The laser 2 adjusts the working distance L of the laser beam 21 by swinging, that is, when the other end of the pull rod 3 is moved along the radial direction of the disc rack 1, the pull rod 3 itself moves radially along the disc rack 1, and the pull rod 3 itself rotates around the connection between it and the laser 2. Driven by the pull rod 3, the laser 2 rotates (sways) around the connection between the laser 2 and the disc rack 1, so the angle θ between the laser 2 and the steel pipe 100 changes, and the working distance L of the laser beam 21 also changes.

[0039] The present invention provides a plurality of lasers 2 arranged in a ring-like interval around a steel pipe 100, and removes rust from the moving steel pipe 100 through a laser beam 21. By setting a pull rod 3 to push the laser 2 to swing, not only can the spacing between the laser 2 and the steel pipe 100 be adjusted to allow steel pipes 100 with different outer diameters to pass through the space inside the plurality of lasers 2, but also the angle θ between the laser 2 and the steel pipe 100 can be adjusted to adjust the working distance L of the laser beam 21, thereby achieving effective rust removal and cleaning of steel pipes 100 with different outer diameters.

[0040] Compared with the existing handheld laser cleaning system, the rust removal and cleaning device of the present invention is fixed and the steel pipe is movable, so there is no need for manual handheld laser, which reduces the labor intensity of workers and has good stability of rust removal quality. Compared with the existing semi-automatic or fully automatic laser cleaning system, the present invention can automatically adjust to adapt to steel pipes with different outer diameters, without manual adjustment, thereby improving production efficiency and reducing economic costs.

[0041] The specific number of lasers can be flexibly selected according to the outer diameter of the steel pipe. Since the cleaning width of each laser is fixed, in order to meet the cleaning of steel pipes with different diameters and circumferences, multiple lasers are usually evenly distributed. According to the number of lasers evenly distributed, when laser guns are used, the rust removal and cleaning device of the present invention can be divided into a three-gun evenly distributed laser rust removal and cleaning device (such as Figure 2 As shown), four-gun uniform laser rust removal and cleaning device (as shown Figure 3 As shown), five-gun uniform laser rust removal and cleaning device (as shown Figure 4 As shown), six-gun uniformly distributed laser rust removal and cleaning device (as shown Figure 5 As shown), or even more rust removal and cleaning devices with evenly distributed laser guns.

[0042] like Figure 1 , Figure 2 As shown, in one embodiment, the laser 2 is hinged to the disc rack 1, and the laser 2 is hinged to the pull rod 3. Specifically, each laser 2 is rotatably connected to the disc rack 1 through a first rotating shaft 4, and each laser 2 is rotatably connected to the pull rod 3 through a second rotating shaft 5. The first rotating shaft 4 and the second rotating shaft 5 are parallel to each other and perpendicular to the axial direction of the steel pipe 100.

[0043] like Figure 1 , Figure 2 As shown, in one embodiment, an annular mounting groove 12 is provided on the other side of the disc frame 1, and the online laser rust removal and cleaning device further comprises a synchronous ratchet disc 6 for connecting the other end of the pull rod 3, the synchronous ratchet disc 6 can be rotatably installed in the mounting groove 12, the synchronous ratchet disc 6 comprises an annular disc body 61 and a plurality of spiny sliding rods 62 arranged on the outer peripheral wall of the disc body 61, the plurality of sliding rods 62 are arranged at intervals along the circumferential direction of the disc body 61, one end of the sliding rod 62 is a fixed end 621 fixedly connected to the disc body 61, and the other end of the sliding rod 62 is The tilted end 622 (or called the free end), each slide bar 62 extends along the circumference of the disk body 61, and each slide bar 62 is inclined from the fixed end 621 to the tilted end 622 in the direction away from the center of the disk body 61. For example, the shape of the slide bar 62 is arc-shaped, and each slide bar 62 can slide through each pull rod 3 respectively. By driving the synchronous ratchet disk 6 to rotate, the pull rod 3 slides along the slide bar 62 and moves along the radial direction of the disk body 61. The pull rod 3 pushes and pulls the laser 2 by moving along the radial direction of the disk body 61, so that the laser 2 swings relative to the disk rack 1.

[0044] exist Figure 2When the synchronous ratchet disk 6 rotates in the clockwise direction, the sliding bar 62 will also move in the clockwise direction, which is equivalent to the other end of the pull rod 3 sliding along the sliding bar 62 toward its fixed end 621, that is, the other end of the pull rod 3 moves inward along the radial direction of the synchronous ratchet disk 6 (or the radial direction of the disk rack 1) under the inner pull of the sliding bar 62, and the pull rod 3 then pulls the laser 2 to rotate, so that the laser 2 swings in the clockwise direction, and the angle θ between the laser 2 and the steel pipe 100 becomes smaller; when the synchronous ratchet disk 6 rotates in the counterclockwise direction, the sliding bar 62 will also move in the counterclockwise direction, which is equivalent to the other end of the pull rod 3 sliding along the sliding bar 62 toward its tilted end 622, that is, the other end of the pull rod 3 moves outward along the radial direction of the synchronous ratchet disk 6 (or the radial direction of the disk rack 1) under the outward push of the sliding bar 62, and the pull rod 3 then pulls the laser 2 to rotate, so that the laser 2 swings in the counterclockwise direction, and the angle θ between the laser 2 and the steel pipe 100 becomes larger.

[0045] In this embodiment, by providing a synchronous ratchet 6, it can not only drive the other end of the pull rod 3 to move along the radial direction of the disk rack 1, but also support the pull rod 3 and the laser 2, and stabilize the laser 2 that has been swung into place in the working position.

[0046] Furthermore, a support tube (not shown) is passed through the through hole 11, and the support tube is fixedly connected to the disk body 61. The movable steel pipe 100 passes through the support tube, and the disk body 61 of the synchronous ratchet 6 can be rotatably mounted outside the support tube. By setting up the support tube, the synchronous ratchet 6 can be supported and kept concentric with the disk body 61.

[0047] Furthermore, the online laser rust removal and cleaning device also includes a driving device for driving the synchronous ratchet disc 6 to rotate.

[0048] Furthermore, the driving device is a worm gear mechanism, the synchronous ratchet plate 6 is connected to the worm gear of the worm gear mechanism, and the motor is used as the power source of the worm gear mechanism. However, the present invention is not limited to this, and other driving devices can also be used to drive the synchronous ratchet plate 6 to rotate, such as using an end face gear (such as an inner hexagon end face gear) to drive, specifically, the end face ( Figure 1 The end face gear is arranged on the right end face in the figure, and each tooth of the end face gear extends along the radial direction of the synchronous ratchet 6. The end face gear is matched with the end face gear on the end face of the disc body 61. When the end face gear is rotated, the synchronous ratchet 6 will also rotate accordingly.

[0049] like Figure 1 As shown, further, the through hole 11, the synchronous ratchet disc 6 and the steel pipe 100 are coaxially arranged. When the disc body 61 is a circular disc, the through hole 11 and the disc body 61 can be coaxially arranged.

[0050] In a specific embodiment, the synchronous ratchet disc 6 is clearance-matched with the mounting groove 12, and the online laser rust removal and cleaning device also includes an annular buckle cover 8, which covers the notch of the mounting groove 12 and is fixedly connected to the disc body 61 to prevent the synchronous ratchet disc 6 from falling out of the mounting groove 12. There is a gap between the synchronous ratchet disc 6 and the buckle cover 8 so that the synchronous ratchet disc 6 can rotate in the mounting groove 12.

[0051] like Figure 1 As shown, further, the disc rack 1 is also provided with a plurality of first embedding grooves 13 for respectively embedding the plurality of lasers 2, and a plurality of second embedding grooves 14 for respectively embedding the plurality of pull rods 3. Both the first embedding grooves 13 and the second embedding grooves 14 are through grooves. The first embedding grooves 13 are arranged obliquely relative to the steel tube 100. The laser 2 passes through the first embedding grooves 13. The width of the first embedding grooves 13 is slightly larger than the width of the laser 2. The first embedding grooves 13 can limit the laser 2 from swinging in the tangential direction of the disc rack 1. The second embedding grooves 14 are arranged obliquely relative to the steel tube 100. The pull rod 3 passes through the second embedding grooves 14. The width of the second embedding grooves 14 is slightly larger than the width of the pull rod 3. The second embedding grooves 14 can limit the pull rod 3 from swinging in the tangential direction of the disc rack 1. The second embedding grooves 14 are connected to the mounting grooves 12 to facilitate the connection between the pull rod 3 and the synchronous ratchet 6.

[0052] like Figure 1 , Figure 2 As shown, in one embodiment, the number of lasers 2 is equal to the number of slide bars 62 , a plurality of lasers 2 are arranged at equal intervals around the steel pipe 100 , and a plurality of slide bars 62 are arranged at equal intervals along the circumferential direction of the disk body 61 .

[0053] like Figure 1 , Figure 2 As shown, in one embodiment, the slide bar 62 is connected to the pull rod 3 via a slide hinge 7, the slide hinge 7 is rotatably embedded in the pull rod 3, and the slide bar 62 passes through the slide hinge 7 and can slide relative to the slide hinge 7. When the synchronous ratchet 6 rotates, the slide bar 62 and the slide hinge 7 slide relative to each other, and the slide hinge 7 rotates relative to the pull rod 3.

[0054] Furthermore, the sliding hinge 7 is a sphere or a sleeve, for example, the sleeve is a copper sleeve.

[0055] When the online laser rust removal and cleaning device of the present invention is used to remove rust from a steel pipe, the laser does not move but the steel pipe moves. By utilizing the surface decontamination capability of the laser, multiple lasers can clean the surface of the steel pipe at different positions. Compared with chemical cleaning, it does not require any chemical agents and cleaning fluids. Compared with mechanical cleaning, it has no grinding, no stress, no consumables, and minimal damage to the substrate. It has a wide range of applications and is an efficient, green, and advanced steel pipe rust removal and cleaning equipment.

[0056] In addition, the rust removal and cleaning device of the present invention can not only remove rust from steel pipes, but also can be used to remove paint, oil stains, mud stains, and coatings (almost all kinds of impurities on the metal surface, including oxides, grease, oil stains, chlorides and many other organic and inorganic residues), with high cleanliness (can remove pollution particles below the nanometer level).

[0058] When the laser beam 21 emitted by the laser 2 of a cleaning device cannot completely cover the outer circumferential wall of the steel pipe 100, by setting up multiple cleaning devices and setting the lasers 2 of the multiple cleaning devices to be staggered in the circumferential direction of the steel pipe 100, the laser beams 21 emitted by the lasers 2 of the multiple cleaning devices can completely cover the outer circumferential wall of the steel pipe 100, thereby improving the rust removal and cleaning effect.
