Description

Technical Field

[0001] This utility model relates to the field of laser cleaning technology, specifically a wide-width laser cleaning machine. Background Technology

[0002] Laser cleaning technology is based on the photophysical reaction between a high-intensity beam of short-pulse laser and a contaminant layer. It uses high-frequency, high-energy laser pulses to irradiate the surface of the object to be cleaned. The contaminants on the surface of the object instantly absorb the laser energy, causing the dirt, rust, or coating on the surface to evaporate or peel off instantly. Under the action of the laser, plasma is formed, generating shock waves that impact the surface of the object, causing the contaminants to break into fragments and be removed. This achieves the purpose of cleaning the surface of the object quickly and effectively by removing the attachments or surface coatings.

[0003] In the prior art, a laser cleaning machine with publication number "CN115608715A" includes a laser cleaning machine body, an optical fiber cable mounted on the laser cleaning machine body, and a handheld laser head mounted at the end of the optical fiber cable. A swing plate is hinged to the side of the laser cleaning machine body, and a handle is hinged to the end of the swing plate. Through the cooperation of these structures, when using the laser cleaning machine to clean objects, the handheld laser head can only be retrieved and used to clean the workpiece after the protective goggles have been pushed out of the storage box. This avoids damage to the eyes caused by operators forgetting to wear protective goggles. Furthermore, when cleaning objects with the handheld laser head, the optical fiber cable is always taut, preventing it from piling up on the ground and causing friction from the ground when the handheld laser head is moved back and forth during use.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] During the use of the aforementioned laser cleaning machine, the laser head needs to be manually held to clean the object. The speed at which the cleaning head is moved manually is uncontrollable. If it is too fast or too slow, the laser will stay on the object for a different amount of time, resulting in uneven cleaning. In addition, it is easy to make mistakes when holding the laser head, which may cause the laser to shine on the operator or nearby people and cause harm to their bodies. Utility Model Content

[0006] The purpose of this invention is to provide a wide-width laser cleaning machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wide-width laser cleaning machine includes a frame, two I-shaped support legs fixedly installed under the frame, two support plates symmetrically arranged on the frame, a slide rod fixedly installed between the two support plates, a slider slidably sleeved on the slide rod, a laser cleaning head fixedly installed on the slider, the laser cleaning head being fixedly connected to a laser via an optical fiber, and the laser being placed on the ground;

[0009] A moving mechanism is provided between the two support plates to enable the laser cleaning head to move at a constant speed.

[0010] The frame is equipped with a conveyor mechanism for intermittently transporting objects to be cleaned.

[0011] Preferably, the moving mechanism includes a reciprocating lead screw rotatably disposed between two support plates, the reciprocating lead screw threaded through the slider, gears fixedly disposed at both ends of the reciprocating lead screw on the outside of the support plates, a gearbox fixedly disposed on the support plates on the gears, and a motor fixedly connected to one end of the reciprocating lead screw, the motor being fixedly disposed on the gearbox by bolts.

[0012] Preferably, the conveying mechanism includes a driving roller and a driven roller rotatably mounted at both ends of the frame, a conveyor belt fitted on the driving roller and the driven roller, a pulley 1 fixedly mounted at both ends of the driving roller, a rotating shaft rotatably mounted inside the gearbox, a gear 2 fixedly mounted inside the gearbox on the rotating shaft, a pulley 2 fixedly mounted outside the gearbox on the rotating shaft, belts fitted on the pulley 1 and pulley 2, and a connecting component on the slider capable of engaging and disengaging the gear 1 and gear 2.

[0013] Preferably, the connecting assembly includes gear columns fixedly disposed on both sides of the slider, a third gear slidably sleeved on the gear column, a push ring fixedly disposed between the gear column and the third gear, a threaded groove formed on the side of the gear column away from the push ring, a nut sleeved on the gear column that can mesh with the threaded groove, and a gear hole formed between the first gear and the second gear on the support plate.

[0014] Preferably, a limiting plate is fixedly provided on one of the support plates, and the limiting plate has a limiting hole through which the optical fiber slides.

[0015] Preferably, the frame is provided with several support rollers rotating in the middle of the conveyor belt.

[0016] Preferably, the gearbox has a support hole through which the gear post can slide in and out;

[0017] Preferably, the laser cleaning head can adjust the width of the emitted laser spot.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. During use, this device can move the laser cleaning head back and forth at a constant speed through the moving mechanism to perform laser cleaning on the objects on the conveyor belt, making the objects cleaned more evenly. Moreover, it is safer because no one needs to hold the laser cleaning head.

[0020] 2. After the laser cleaning head cleans the object on the conveyor belt, the connecting component drives the conveying mechanism to move the object forward a certain distance. When the laser cleaning head moves back, it can directly perform subsequent cleaning work on the object, thereby saving a lot of time and improving cleaning efficiency.

[0021] 3. Since the laser cleaning head can adjust the width of the emitted laser spot, the area cleaned by the laser cleaning head when it moves laterally will also be different. However, the moving speed of the slider is constant. The engagement time of gear one, gear two and gear three can be controlled by adjusting the distance between the slider and the push ring through the nut. This adjusts the distance of the intermittent movement of the conveyor belt, thus ensuring that no object is missed during cleaning. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: Example

[0030] A wide-width laser cleaning machine includes a frame 1. Two I-shaped support legs 2 are fixedly mounted under the frame 1. Two support plates 3 are symmetrically arranged on the frame 1. A slide rod 4 is fixedly mounted between the two support plates 3. A slider 5 is slidably mounted on the slide rod 4, and the slider 5 can slide along the slide rod 4. A laser cleaning head 6 is fixedly mounted on the slider 5. The laser cleaning head 6 can move with the slider 5 and emits a laser spot or band downwards. The width of the emitted laser spot can be adjusted. The optical fiber 7 is fixedly connected to the laser 8, which is placed on the ground. The laser 8 can generate laser light, which is then transmitted to the laser cleaning head 6 through the optical fiber 7. The laser light is emitted by the adjustment inside the laser cleaning head 6. This is existing technology and will not be described in detail here. A limit plate 28 is fixedly installed on one of the support plates 3. The limit plate 28 has a limit hole 29 through which the optical fiber 7 slides. The limit plate 28 is set to prevent the optical fiber 7 from falling under the laser cleaning head 6 and being damaged, and also to facilitate the movement of the slider 5 and the laser cleaning head 6.

[0031] A moving mechanism is provided between the two support plates 3 to enable the laser cleaning head 6 to move at a uniform speed. The moving mechanism includes a reciprocating screw 9 rotatably arranged between the two support plates 3. The reciprocating screw 9 is threaded through the slider 5. Gears 10 are fixedly arranged at both ends of the reciprocating screw 9 on the outside of the support plates 3. A gearbox 11 is fixedly arranged on the support plates 3 on the gears 10. A motor 12 is fixedly connected to one end of the reciprocating screw 9. The motor 12 is fixedly arranged on the gearbox 11 by bolts.

[0032] When the motor 12 is powered on and rotates, it drives the reciprocating screw 9 to rotate together. Since the several protrusions inside the slider 5 at the reciprocating screw 9 are inserted into the bidirectional threaded groove of the reciprocating screw 9, and the other side of the slider 5 is sleeved on the slide rod 4, the rotation of the reciprocating screw 9 will cause the slider 5 to move back and forth on the reciprocating screw 9. At the same time, the rotation of the reciprocating screw 9 will drive the gear 10 on it to rotate together. Example

[0033] The frame 1 is equipped with a conveying mechanism for intermittently transporting objects to be cleaned. The conveying mechanism includes a drive roller 30 and a driven roller 13 that are rotatably mounted at both ends of the frame 1. A conveyor belt 25 is mounted on the drive roller 30 and the driven roller 13. When the drive roller 30 rotates, the conveyor belt 25 moves, thereby driving the driven roller 13 to rotate. Several support rollers 27 are rotatably mounted in the middle of the conveyor belt 25, which can support the objects on the conveyor belt 25 and rotate voluntarily without affecting the movement of the conveyor belt 25 and the objects on it. Pulley 14 is fixedly mounted at both ends of the drive roller 30. A rotating shaft 15 is rotatably mounted inside the gearbox 11. A gear 16 is fixedly mounted inside the gearbox 11 on the rotating shaft 15. Pulley 17 is fixedly mounted outside the gearbox 11 on the rotating shaft 15. A belt 18 is mounted on the pulley 14 and the pulley 17.

[0034] When gear 16 rotates, it drives shaft 15 to rotate, which in turn drives pulley 17 to rotate. Pulley 17 then drives pulley 14 to rotate via belt 18, thereby driving drive roller 30 to rotate.

[0035] The slider 5 is equipped with a connecting component that enables the engagement and disengagement of gear 10 and gear 26. The connecting component includes gear posts 19 fixedly mounted on both sides of the slider 5, gear 3 20 slidably mounted on the gear posts 19, and a push ring 21 fixedly mounted between the gear posts 19 and gear 3 20. The push ring 21 can push gear 3 20 to move. A threaded groove 22 is opened on the side of the gear posts 19 away from the push ring 21. A nut 23 that can mesh with the threaded groove 22 is mounted on the gear posts 19. The nut 23 can rotate at the threaded groove 22 of the gear posts 19 and move by rotation. A gear hole 24 is opened between gear 10 and gear 26, through which gear 3 20 can pass. A support hole 26 is opened in the gear box 11, through which gear posts 19 can slide in and out. When gear 3 20 enters the gear box 11, gear posts 19 will be inserted into the support hole 26, thereby locking the suspended end of gear posts 19 and providing support for gear posts 19.

[0036] When the slider 5 moves close to the support plate 3, the gear column 19 is inserted into the support hole 26, and the gear 3 20 also enters the gearbox 11 from the gear hole 24, and meshes with the gear 1 10 and the gear 2 16 respectively. Since the gear 1 10 rotates with the reciprocating screw 9, it drives the gear 2 16 to rotate through the meshing gear 3 20. The gear 2 16 then drives the rotating shaft 15 to rotate, thereby driving the conveyor belt 25 to move.

[0037] Working principle: First, place the object to be cleaned on the conveyor belt 25. Then, adjust the width of the laser emitted by the laser cleaning head 6. Next, rotate the nut 23 to adjust the distance between the nut 23 and the push ring 21. Then, turn on the laser 8 and the motor 12. The motor 12 drives the reciprocating screw 9 to rotate. The rotating reciprocating screw 9 causes the slider 5 to move on it. When the slider 5 moves and comes into contact with a support plate 3, the gear column 19 is inserted into the support hole 26. The third gear 20 is pushed by the push ring 21, passes through the gear hole 24, and enters the gearbox 11. At this time, the third gear 20 meshes with the first gear 10 and the second gear 16 respectively. The reciprocating screw 9 drives the rotating shaft 15 to rotate through the gears 10, 16, and 20. The rotating shaft 15 drives the drive roller 30 to rotate through the cooperation of the pulley 14, pulley 27, and belt 18, so that the conveyor belt 25 moves forward, thereby moving the object forward.

[0038] As the reciprocating screw 9 continues to rotate, the slider 5 moves toward the support plate 3 on the other side, causing the gear column 19 to move as well. When the nut 23 is pressed against the gear 3 20, it pushes the gear 3 20 out of the gearbox 11. The gear 3 20 no longer meshes with the gear 1 10 and the gear 2 16, so the drive roller 30 loses power and stops rotating. The conveyor belt 25 and the objects on it also stop moving. The slider 5 drives the laser cleaning head 6 to move toward the support plate 3 on the other side, thereby cleaning the objects until the gear 3 20 on the other side meshes with the gear 1 10 and the gear 2 16 on the other side. The above process is repeated, so that when the laser cleaning head 6 cleans the objects, the objects do not move. When the laser cleaning head 6 is pressed against the support plate 3, the objects can move a certain distance and then stop again. The laser cleaning head 6 then cleans the uncleaned parts of the objects.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
