Description

Technical Field

[0001] This invention relates to the field of rust removal equipment technology, specifically to an automatic laser rust removal device for steel pipes. Background Technology

[0002] In the industrial production field, steel pipes are a widely used basic component. Surface rust removal is a key step to ensure the quality of subsequent processing and extend service life. With the acceleration of industrialization, the requirements for the efficiency and quality of rust removal of steel pipes are increasing. Automatic laser rust removal equipment for steel pipes has emerged to replace traditional manual rust removal through automation and improve work efficiency. However, existing automatic laser rust removal equipment for steel pipes still has many defects in practical applications. In terms of clamping and fixing, the clamping mechanism of traditional equipment is difficult to adapt to steel pipes of different specifications, and often the clamping is unstable, causing the steel pipes to shake during the rust removal process, which seriously affects the accuracy of laser rust removal and cannot guarantee the uniformity of the surface after rust removal.

[0003] In terms of the design of the flipping mechanism, the existing equipment lacks effective anti-reverse measures. The steel pipes are prone to reverse rotation during the flipping process, resulting in poor stability and safety, and there is a risk that the steel pipes may fall or be damaged. At the same time, when it is necessary to remove rust from the other side of the steel pipes, the flipping operation is mostly done manually, which not only increases labor costs but also interrupts the continuity of the operation and reduces the overall production efficiency.

[0004] In the impurity removal stage, the existing equipment is not capable of handling the impurities generated during the rust removal process. Laser rust removal produces a large amount of rust chips and other impurities. If these impurities are not cleaned in time, they will remain on the surface of the steel pipes, affecting subsequent rust removal operations and even causing some wear to the equipment itself. Although some equipment has a simple cleaning structure, the cleaning effect is not good, and it is impossible to achieve efficient collection and removal of impurities, making it difficult to guarantee the cleanliness of the rust removal process.

[0005] In terms of cleaning, existing equipment does not clean the surface of steel pipe fittings thoroughly enough. Even after rust removal and preliminary cleaning, fine stains and dust may still remain on the surface of the steel pipe fittings. The cleaning mechanism of existing equipment is often unable to effectively deal with these residual impurities, resulting in insufficient purity of the surface of the steel pipe fittings after rust removal, which has an adverse effect on subsequent processing or use.

[0017] As a further preferred embodiment of this technical solution, a second triangular block is fixedly installed on the top of the connecting block, an inlet pipe is connected to the top of the water tank, a drain hole is provided at the bottom of the inlet pipe, a pressure plate is slidably connected inside the water tank, and a seventh damping spring is provided at the bottom of the pressure plate. L-shaped rods are slidably connected to both sides of the top of the pressure plate, the L-shaped rods are slidably connected to the top of the water tank, and the positions of the L-shaped rods and the second triangular block correspond to each other.

[0018] Compared with existing technologies, it has the following advantages:

[0019] The left and right clamping frames securely hold the steel pipe fittings. The combination of the splined rod and sleeve rod, along with the elasticity of the second damping spring, allows for the adaptation to different specifications of steel pipe fittings, ensuring that the fittings do not wobble during rust removal and further guaranteeing rust removal accuracy. The anti-reverse mechanism, composed of a ratchet and pawl, effectively prevents the ratchet from rotating in the opposite direction under the action of a torsion spring, ensuring the stability and safety of the steel pipe fitting during flipping and avoiding the risk of the fitting falling or being damaged due to unstable flipping. When rust removal is needed on the other side of the steel pipe fitting, the trapezoidal block is moved by the control component, driving the first toothed rod to mesh with the first gear, achieving a 180-degree rotation of the steel pipe fitting. This eliminates the need for manual flipping, saving labor costs and improving work continuity. Furthermore, the rotation of the rotating rod drives the ratchet and reciprocating component to rotate. The reciprocating component, in conjunction with the ball bearing, causes the striking rod to reciprocate under the action of the third damping spring, striking the right clamping frame. The vibration is transmitted to the steel pipe fittings, which can promptly clean up impurities generated during rust removal, ensuring the cleanliness of the rust removal process. The cleaning component further improves the quality of the rust removal effect. It can promptly remove surface impurities and dust during the turning and rust removal process of the steel pipe fittings, avoiding the impact of residual impurities on subsequent rust removal operations, ensuring the purity of the surface of the steel pipe fittings after rust removal, and providing a good foundation for subsequent processing or use. From the overall workflow, the equipment has a high degree of automation and is easy to operate. From clamping and fixing the steel pipe fittings to the automatic turning after one side is rusted, and then to the rust removal and impurity cleaning of the other side, the entire process requires little manual intervention. This not only reduces the labor intensity of manual operation, but also reduces the impact of human factors on the quality of operation. The equipment can complete the rust removal task of steel pipe fittings efficiently and with high quality, saving enterprises time and costs, improving production efficiency, and is suitable for large-scale, batch rust removal operations of steel pipe fittings.

[0020] The cylindrical surface is covered with densely packed bristles of moderate texture, which effectively remove impurities from the steel pipe surface during rotation without damaging it. Simultaneously, the hollow design of the cylinder with multiple evenly distributed through-holes, combined with the powerful suction generated by the pump, creates a negative pressure environment within the semi-circular frame. Impurities can quickly enter the cylinder through these through-holes and then be sucked into the collection box via the connecting pipe. This design ensures high efficiency in impurity cleaning and collection, providing a clean working surface for subsequent processing. The fixed plates on both sides of the semi-circular frame are equipped with scrapers at their bottom ends. These scrapers are made of high-quality materials, have a smooth surface and a certain degree of hardness, and can closely adhere to the steel pipe surface. As the sliding frame and semi-circular frame move laterally, the scrapers effectively remove firmly attached impurities that are difficult to remove by the bristles, further ensuring the cleanliness of the steel pipe surface and enhancing the cleaning effect.

[0021] As the sliding frame and semi-circular frame move, the water tank moves accordingly, allowing the internal cleaning fluid to gradually penetrate the sponge pad, keeping it moist. When the sponge pad contacts the surface of the steel pipe, it evenly spreads the cleaning fluid, meticulously wiping areas where impurities have been scraped away, removing any remaining fine stains and dust, resulting in a cleaner surface for the steel pipe. Rollers on the outer end of the connecting block push the first triangular blocks on both sides of the water tank, causing the water tank and sponge pad to move downwards synchronously. The sixth damping spring is compressed, generating elastic potential energy, ensuring the sponge pad maintains a constant, tight seal against the steel pipe surface. This moderate pressure ensures the cleaning fluid is evenly applied while preventing damage to the steel. Damage to the pipe fitting surface is caused when the sliding frame and semi-circular frame return to their initial positions. The bidirectional screw rotates in the opposite direction, and the sixth damping spring releases its elastic potential energy, pushing the water tank and sponge pad upwards back to their initial height for the next cleaning and wiping action, thus achieving a comprehensive cleaning of the steel pipe fitting surface. When the second triangular block moves inwards synchronously with the connecting block, it pushes the L-shaped rod downwards. The L-shaped rod drives the pressure plate to slide inside the water tank and squeezes the water downwards. Under pressure, the water flows from the inlet pipe into the pressure plate, making the pressure plate wet. When the wet pressure plate comes into contact with the surface of the steel pipe fitting, it can scrub the surface of the steel pipe fitting, further improving the cleaning effect and realizing the rational use of the cleaning solution.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Combining Figures 1-9 As shown, the present invention provides a technical solution: an automatic laser rust removal device for steel pipes, including a worktable 1 and a steel pipe 6. The top of the worktable 1 is provided with a horizontal sliding rail, and a support platform 2 is slidably mounted on the top of the worktable 1 along this rail. The support platform 2 serves as a carrier platform for the laser emitter 3. Its structural design fully considers stability and flexibility of movement. The laser emitter 3 is stably mounted on one end. The laser emitter 3 has the characteristics of high energy and high focusing, and can perform precise rust removal on the surface of the steel pipe 6.

[0034] Rotating rollers 11 are rotatably mounted on both sides of the workbench 1. One of the rotating rollers 11 is equipped with a control motor 12 at its end. The control motor 12 serves as the power source, and its performance directly affects the operating efficiency of the entire equipment. The outer walls of the two rotating rollers 11 are tightly connected to the conveyor belt 13 through specially designed conveyor wheels. The design of the conveyor wheels is optimized, providing good friction and transmission efficiency with the conveyor belt 13, ensuring stable power transmission. The support platform 2 is securely mounted on the conveyor belt 13 through a reliable fixing method. When the control motor 12 is turned on, it acts as a forward and reverse motor, driving the rotating rollers 11 to rotate forward or in the reverse direction according to the control signal. The rotation of the rotating rollers 11 drives the conveyor belt 13 to move laterally through the conveyor wheels, thereby driving the support platform 2 and the laser emitter 3 to move laterally on the workbench 1, enabling the laser emitter 3 to perform comprehensive and meticulous rust removal treatment on the surface of the steel pipe 6.

[0035] A first fixed frame 4 is fixedly installed on the front surface of the workbench 1. A flipping assembly 5 is provided on the first fixed frame 4. The flipping assembly 5 includes a left clamping frame 53 and a right clamping frame 57 installed on both sides of the inner cavity of the first fixed frame 4. These two clamping frames are key components for fixing the steel pipe fitting 6. A rotating rod 56 is fixedly connected to the right end of the right clamping frame 57. The rotating rod 56 is rotatably mounted on the first fixed frame 4 through a high-precision rotating bearing, ensuring the flexibility of rotation. A first gear 58 is fixedly connected to the right end of the rotating rod 56. The first gear 58 serves as a transmission component, capable of transmitting power to the rotating rod 56. A fixed mounting bracket is provided above the first gear 58. The mounting bracket 515 on the workbench 1 provides a stable mounting base for other components. A second crossbar 517 is laterally slidable on the surface of the mounting bracket 515. To ensure the stability of the sliding of the second crossbar 517, a sliding groove is provided on the surface of the mounting bracket 515. A first sliding rod 516 is fixedly installed in the sliding groove. The second crossbar 517 is laterally slidably installed on the first sliding rod 516. A fourth damping spring 518 is provided on the right side of the second crossbar 517 and sleeved on the first sliding rod 516. Under the elastic force of the fourth damping spring 518, the second crossbar 517 can move to the right and reset, ensuring the automatic return function of the component.

[0036] The surface of the second crossbar 517 is slidably connected to the first toothed rod 519 in the vertical direction. The first toothed rod 519 is fixedly mounted on both sides of the first slide rod 519. The second crossbar 517 is fixedly connected to both sides of the second slide rod 522. The second slide rod 521 is slidably mounted on the positioning block 522. The top of the positioning block 522 is provided with a fifth damping spring 523 sleeved on the second slide rod 521. Under the elastic force of the fifth damping spring 523, the first toothed rod 519 and the trapezoidal block 520 can move upward and reset. The position of the first toothed rod 519 is adapted to the position of the first gear 58. When the first toothed rod 519 moves up and down, it can mesh with the first gear 58, thereby driving the first gear 58 to rotate. The top of the first toothed rod 519 is fixedly mounted with the trapezoidal block 520. The position of the trapezoidal block 520 and the second crossbar 517 is adapted to the position of the control component. The control component can accurately control the movement of the trapezoidal block 520, thereby realizing the control of the rotation of the first gear 58.

[0037] A sleeve rod 51 is rotatably connected to the left side of the inner cavity of the first fixed frame 4. A spline rod 52 is slidably connected to the inner side of the sleeve rod 51. The other end of the spline rod 52 is fixedly connected to the left clamping frame 53. This design allows the left clamping frame 53 to move in the horizontal direction. A second damping spring 54 is provided between the sleeve rod 51 and the left clamping frame 53 and sleeved on the spline rod 52. When installing the steel pipe 6, the left clamping frame 53 is controlled to move to the left and compress the second damping spring 54. Then the steel pipe 6 is placed between the left clamping frame 53 and the right clamping frame 57. The second damping spring 54 is released. The elastic force of the second damping spring 54 is used to push the left clamping frame 53 to move to the right clamping frame 57. Thus, the steel pipe 6 can be firmly clamped and fixed by the left clamping frame 53 and the right clamping frame 57.

[0038] A ratchet 59 is mounted on the outer wall of the rotating rod 56 via a torsion spring. A pawl 510, which is compatible with the ratchet 59, is mounted on the outer wall of the first fixed frame 4. The ratchet 59 and the pawl 510 form an anti-reverse mechanism. Under the action of the torsion spring and the ratchet 59, the ratchet 59 can be effectively prevented from rotating in the opposite direction, ensuring the stability and safety of the steel pipe 6 during the flipping process. A striking rod 511 is slidably mounted on both sides of the first fixed frame 4. A ball 512 is fixedly connected to one end of the striking rod 511 near the ratchet 59, and the other end corresponds to the position of the right clamping frame 57. A gap is provided between the ball 512 and the first fixed frame 4. The third damping spring 513 is sleeved on the striking rod 511. The ratchet 59 has a reciprocating part 514 arranged in a circumferential array on its surface, and the reciprocating part 514 is matched with the position of the ball 512. When the rotating rod 56 rotates, it can drive the ratchet 59 and the first toothed rod 519 to rotate synchronously. The rotating reciprocating part 514, together with the elastic force of the third damping spring 513, can drive the striking rod 511 to move back and forth. The striking rod 511 strikes the right clamping frame 57, thereby transmitting the vibration to the steel pipe 6. When the steel pipe 6 is flipped, the impurities generated by rust removal are vibrated and cleaned.

[0039] The top of the first fixed frame 4 is equipped with a cleaning component 7 for cleaning impurities on the surface of the steel pipe fitting 6. The cleaning component 7 adopts advanced cleaning technology, which can remove impurities and dust from the surface in a timely manner during the turning and rust removal process of the steel pipe fitting 6, ensuring the purity and quality of the rust removal effect.

[0040] In an embodiment of the present invention, the steel pipe 6 is first placed between the left clamping frame 53 and the right clamping frame 57. The steel pipe 6 is clamped and fixed by controlling the movement of the left clamping frame 53. Then, the laser emitter 3 is turned on, and the control motor 12 is started at the same time, so that the support platform 2 and the laser emitter 3 move laterally on the worktable 1 to remove rust from one side of the steel pipe 6. After the rust removal is completed on one side, the trapezoidal block 520 is moved by the control component, which drives the first gear 519 to mesh with the first gear 58, so that the first gear 58 rotates 180 degrees, thereby driving the rotating rod 56. The right clamping frame 57, the left clamping frame 53, and the steel pipe 6 rotate 180 degrees to remove rust from the other side of the steel pipe 6. During the rotation, the rotating rod 56 drives the ratchet 59 to rotate, and the reciprocating part 514 interacts with the ball 512 to make the striking rod 511 move back and forth to strike the right clamping frame 57, transmitting the vibration to the steel pipe 6 to clean the impurities generated during rust removal. At the same time, the cleaning component 7 continues to work to further ensure the cleanliness of the surface of the steel pipe 6. The whole process is highly automated, easy to operate, and can complete the rust removal task of the steel pipe 6 efficiently and with high quality.

[0041] Example 2: Combination Figure 2As shown, based on Embodiment 1, the control component includes a first horizontal bar 21 fixedly installed on the support platform 2. A push block 22 and a rectangular block 23 are fixedly installed on both sides of the bottom end of the first horizontal bar 21, and the positions of the push block 22 and the trapezoidal block 520 correspond to each other. The positions of the rectangular block 23 and the second horizontal bar 517 correspond to each other. A push rod 24 is laterally slidably connected to the end of the rectangular block 23 near the second horizontal bar 517. A first damping spring 25 is provided on the inner end of the push rod 24, and the elastic force of the first damping spring 25 is greater than the elastic force of the fourth damping spring 518. A connecting frame 26 is fixedly installed on the outer end of the support platform 2, and the connecting frame 26 is fixedly connected to the sliding frame 72.

[0042] In an embodiment of the present invention, when the support platform 2 and the laser emitter 3 move to the right, the laser emitter 3 is used to remove rust from the steel pipe 6. After the rust removal work on one side of the steel pipe 6 is completed, when the support platform 2 continues to move to the right, the support platform 2 can drive the first horizontal bar 21, the push block 22, the rectangular block 23, and the push rod 24 to move synchronously. The push rod 24 first contacts the second horizontal bar 517, and as the support platform 2 continues to move to the right, the push rod 24 can push the second horizontal bar 517 to move to the right and compress the fourth damping spring 518, thereby causing the second horizontal bar 517 to drive the first toothed bar 519 to move synchronously to the right. The movement causes the first toothed rod 519 to move to the position where it meshes with the first gear 58. At this time, the second crossbar 517 has moved to the rightmost position and will not move to the right again under the blocking action of the mounting bracket 515. As the support platform 2 continues to move to the right, the push rod 24 retracts into the rectangular block 23 and compresses the first damping spring 25. At this time, the push block 22 moves to the position of the trapezoidal block 520 and pushes the trapezoidal block 520 and the first toothed rod 519 downward and compresses the fifth damping spring 523. This causes the first toothed rod 519 to drive the meshing first gear 58 to rotate 180 degrees, thereby driving the steel pipe 6 to flip.

[0043] After the steel pipe 6 is flipped, the control support platform 2 and the laser emitter 3 move to the left, so that the push block 22 moves to a position where it is no longer in contact with the trapezoidal block 520. At this time, because the pawl 510 engages with the ratchet 59, the first gear 58 will not rotate in the opposite direction. That is to say, at this time, the fifth damping spring 523 will not push the first toothed rod 519 and the trapezoidal block 520 to move upward and reset. When the push rod 24 moves to a position where it is no longer in contact with the second crossbar 517, under the elastic force of the fourth damping spring 518, the second crossbar 517 and the first toothed rod 519 are pushed to move to the left and reset. When the first toothed rod 519 moves to the left, it separates from the first gear 58 and is no longer engaged. At this time, under the elastic force of the fifth damping spring 523, the first toothed rod 519 and the trapezoidal block 520 are pushed to move upward and reset.

[0044] Example 3: Combination Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, based on Embodiment 2, the core part of the cleaning component 7 includes a positioning frame 71 fixedly installed on the front and rear ends of the surface of the first fixed frame 4. The positioning frame 71 serves as the support structure for the entire cleaning component. A sliding frame 72 is slidably connected to its top. This design allows the sliding frame 72 to move smoothly and precisely along the positioning frame 71. A cylinder 74 is rotatably connected to the inner end of the sliding frame 72. The surface of the cylinder 74 is evenly covered with dense bristles 75. These bristles 75 are of moderate texture, which can effectively brush off impurities from the surface of the steel pipe 6 without damaging the surface of the steel pipe 6. The cylinder 74 adopts a hollow structure design and has multiple through holes 76 on its surface. These through holes 76 are evenly distributed and of moderate size, which can ensure that impurities can smoothly enter the interior of the cylinder 74 and prevent the bristles 75 from being sucked into the interior of the cylinder 74 during rotation.

[0045] During the cleaning process, the sliding frame 72 is controlled by the support platform 2 and the connecting frame 26 to slide laterally on the positioning frame 71. The sliding frame 72 drives the semi-circular frame 73 and the cylinder 74 to move synchronously. When the cylinder 74 moves to the surface of the steel pipe 6, the pump body is started, and the pump body begins to work and generate a strong suction force. This suction force is transmitted to the semi-circular frame 73 through the connecting pipe 725, so that a negative pressure environment is formed inside the semi-circular frame 73. At this time, the bristles 75 on the surface of the cylinder 74 come into close contact with the surface of the steel pipe 6 during the rotation process, cleaning the surface of the steel pipe 6. Impurities on the surface are brushed off. Under negative pressure, these impurities quickly enter the interior of the cylinder 74 through the through holes 76 on the surface of the cylinder 74, and are then sucked into the collection box 726 through the connecting pipe 725. The collection box 726 is reasonably designed and has a moderate capacity to meet the needs of long-term cleaning work. It is also equipped with a filter device to effectively prevent impurities from re-entering the cleaning system. Through this series of operations, the cleaning and collection of impurities on the surface of the steel pipe fitting 6 are achieved, creating good conditions for subsequent rust removal treatment using the laser emitter 3.

[0046] In addition to the cleaning function of the cylinder 74 and the brush 75, the outer walls of the semi-circular frame 73 are also fixedly installed with fixing plates 79. The bottom of the fixing plates 79 is provided with scrapers 710 for cleaning impurities on the surface of the steel pipe fitting 6. The scrapers 710 are made of high-quality materials, with a smooth surface and a certain degree of hardness, and can fit tightly against the surface of the steel pipe fitting 6. During the lateral movement of the sliding frame 72 and the semi-circular frame 73, the scrapers 710, due to their tight fit against the surface of the steel pipe fitting 6, effectively scrape off those impurities that are more firmly attached and not easy to be brushed off by the brush 75. This design further ensures the cleanliness of the surface of the steel pipe fitting 6 and provides a cleaner working surface for subsequent processing.

[0047] A second fixing frame 711 is fixedly installed on the outer end of the fixing plate 79. A third sliding rod 712 is fixedly installed on the inner side of the second fixing frame 711. A water tank 713 is slidably connected to the third sliding rod 712. The water tank 713 is reasonably designed with sufficient internal space to store enough cleaning fluid. A sixth damping spring 714 is sleeved on the outer wall of the third sliding rod 712. The sixth damping spring 714 has a certain elastic coefficient and can deform when the water tank 713 is subjected to external force and quickly return to its original shape after the external force disappears. A sponge pad 715 for wiping the surface of the steel pipe 6 is provided at the bottom of the water tank 713. The sponge pad 715 is soft and highly absorbent, and can evenly absorb the cleaning fluid in the water tank 713 and evenly spread it on the surface of the steel pipe 6 when in contact with it.

[0048] As the sliding frame 72 and the semi-circular frame 73 move, the water tank 713 moves along with them. The cleaning fluid stored inside gradually seeps into the sponge pad 715, keeping the sponge pad 715 moist. As the sponge pad 715 moves, it continuously comes into contact with the surface of the steel pipe 6, evenly applying the cleaning fluid to the surface of the steel pipe 6. This operation meticulously wipes the area after scraping off impurities, removing any possible residual fine stains and dust, making the surface of the steel pipe 6 cleaner. This clean state creates favorable conditions for the subsequent rust removal treatment of the laser emitter 3, ensuring a more ideal rust removal effect.

[0049] To further improve the adhesion between the sponge pad 715 and the surface of the steel pipe fitting 6, a double-acting lead screw 78 is rotatably connected to the top of the fixing plate 79. A second gear 723 is fixedly connected to both ends of the double-acting lead screw 78. A second rack 724 is meshed with the bottom end of the second gear 723, and the second rack 724 is fixedly mounted on the positioning frame 71. When the sliding frame 72 and the semi-circular frame 73 move laterally, the second gear 723 meshes with the second rack 724 during the lateral movement, causing rotation. The second gear 723 drives the double-acting lead screw 78 to rotate. Connecting blocks 77 are threaded to both sides of the double-acting lead screw 78, and the connecting blocks 77 are laterally slidably mounted on the fixing plate 79. Under the rotation of the double-acting lead screw 78, the two connecting blocks... 77 moves inward synchronously. A roller 716 is provided on the outer end of the connecting block 77. The water tank 713 is fixedly connected to the two sides of the first triangular block 717, and the roller 716 is located on the top of the first triangular block 717. When the connecting block 77 drives the roller 716 to move synchronously, the roller 716 pushes the first triangular block 717 to move downward, and drives the water tank 713 and the sponge pad 715 to move downward synchronously. During the downward movement, the sixth damping spring 714 is compressed and generates elastic potential energy. This design allows the sponge pad 715 to continuously and tightly adhere to the surface of the steel pipe 6 with a certain pressure. This moderate pressure can ensure that the cleaning liquid is fully and evenly applied to the surface of the steel pipe 6, and can also avoid damage to the surface of the steel pipe 6 due to excessive pressure.

[0050] When the sliding frame 72 and the semi-circular frame 73 complete their lateral movement and are ready to return to their initial positions, the double-acting screw 78 rotates in the opposite direction. Under the action of the reverse rotation of the double-acting screw 78, the two connecting blocks 77 move outward synchronously. The connecting blocks 77 drive the roller 716 to move outward. At this time, the sixth damping spring 714 releases its elastic potential energy, pushing the water tank 713 and the sponge pad 715 to move upward back to their initial height. This design allows the sponge pad 715 to return to its initial state after each cleaning, so that it can perform the next cleaning and wiping action. This cycle repeats, achieving a comprehensive and meticulous cleaning treatment of the surface of the steel pipe 6, laying a solid foundation for the subsequent rust removal process of the laser emitter 3.

[0051] In addition, to further improve the cleaning effect, a second triangular block 722 is fixedly installed on the top of the connecting block 77. A water inlet pipe 718 is connected to the top of the water tank 713, and a drain hole 719 is provided at the bottom of the water inlet pipe 718. The drain hole 719 is of moderate size and can control the outflow speed of the cleaning liquid. A pressure plate 720 is slidably connected inside the water tank 713, and a seventh damping spring 727 is provided at the bottom of the pressure plate 720. The seventh damping spring 727 has a certain elastic coefficient and can deform when the pressure plate 720 is subjected to external force, and quickly return to its original shape after the external force is removed. L-shaped rods 721 are slidably connected to both sides of the top of the pressure plate 720. The L-shaped rods 721 are slidably connected to the top of the water tank 713, and the L-shaped rods 721 are connected to the second The positions of the triangular blocks 722 correspond to each other. When the second triangular block 722 moves inward synchronously with the connecting block 77, it can push the L-shaped rod 721 downward. The L-shaped rod 721 drives the pressure plate 720 downward, causing the pressure plate 720 to slide in the water tank 713 and squeeze the water downward. Under pressure, the water flows from the water inlet pipe 718 into the interior of the pressure plate 720, making the pressure plate 720 wet. When the wet pressure plate 720 comes into contact with the surface of the steel pipe fitting 6, it can wipe the surface of the steel pipe fitting 6, further improving the subsequent rust removal efficiency. This design makes full use of the mechanical movement in the cleaning process, realizes the automatic replenishment of cleaning fluid and enhances the wiping function, and provides strong support for the performance improvement of the entire cleaning assembly.
