Description

Technical Field

[0001] The present invention belongs to the technical field of laser cleaning machines, and in particular, relates to a high-efficiency laser cleaning machine and a method for using the same. Background Art

[0002] As a new surface treatment process, laser cleaning technology has been gradually developed since the 1990s. With its advantages of non-contact, no chemical pollution, high precision and selective cleaning, it has been applied in aerospace, precision electronics, cultural relics restoration and rail transportation. Its principle is to use a high-energy laser beam to act on pollutants on the surface of the material (such as oxides, oil stains, coatings, etc.), and use the difference in laser absorption rate between pollutants and substrates to instantly vaporize or peel off the pollutants while avoiding damage to the base material. Compared with traditional sandblasting, chemical solvent cleaning or mechanical polishing, laser cleaning technology is green and environmentally friendly, and can be digitally controlled, which meets the needs of modern manufacturing for efficient cleaning and sustainable development. However, existing laser cleaning equipment still has significant technical bottlenecks in practical applications:

[0003] 1. Traditional laser cleaning machines often have a simple structural design and relatively fixed cleaning movements, making it difficult to achieve comprehensive and rapid cleaning. For example, for some complex-shaped workpieces, conventional laser cleaning machines may not be able to efficiently clean all parts, resulting in low overall cleaning efficiency and difficulty meeting the needs of large-scale industrial production.

[0004] 2. A large amount of dust will be generated during the laser cleaning process. This dust will not only pollute the working environment and affect the health of the operators, but may also cause damage to the laser cleaning equipment itself, such as affecting the transmission accuracy of the laser light path. Currently, the dust treatment devices of most laser cleaning machines are not effective and cannot effectively collect and filter dust.

[0005] 3. When facing workpieces with convex heads or uneven surfaces, existing laser cleaning machines have difficulty in automatically adjusting the laser head angle to adapt to different surface conditions, resulting in unsatisfactory cleaning effects and inability to ensure consistent cleaning quality;

[0006] To solve the above problems, this application proposes a high-efficiency laser cleaning machine and a method for using the same. Summary of the Invention

[0007] In response to the problems in the related art, the present invention proposes a high-efficiency laser cleaning machine and a method of using the same to overcome the above-mentioned technical problems existing in the existing related art.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A high-efficiency laser cleaning machine and a method for using the same machine include a base plate, four support rods fixedly mounted on the top of the base plate, a fixed ring fixedly mounted on the top ends of the four support rods, a load-bearing ring provided between the fixed ring and the base plate, an air ring box rotatably connected to the inner side of the load-bearing ring, four symmetrically arranged lifting ears fixedly mounted on the outer side of the load-bearing ring, the lifting ears being slidably connected to the corresponding support rods, a controller installed on one side of the fixed ring, a placement plate fixedly mounted on the top of the base plate, and two laser heads rotatably connected to the inner side of the air ring box;

[0010] The driving mechanism includes a plurality of air spray heads, a plurality of corner elbows are rotatably installed on the inner side of the air ring box, and the air spray heads are connected to the corresponding corner elbows;

[0011] The direction adjustment mechanism includes multiple drive rings, which are rotatably mounted on the inner side of the air ring box. Multiple springs are fixedly mounted on the inner side of the drive rings, and the springs are connected to the corresponding corner bends.

[0012] The convex head side cleaning mechanism includes two cylinders, which are installed on the inner side of the air ring box. Push rings are installed on the pistons of the two cylinders, and the push rings are transmission-connected with the laser head.

[0013] Preferably, the driving mechanism also includes two exhaust fans, which are installed on the top of the air ring box. Two filter boxes are installed on the top of the air ring box. A duct is connected to the filter box, which is connected to the exhaust fan, and the filter box and the air ring box are connected to each other. One side of the filter box is set with an opening, and a filter core is slidably connected in the filter box. A baffle is installed on one side of the filter core, and the baffle cooperates with the opening.

[0014] Through the setting of the exhaust fan, the dust generated during laser cleaning can be easily sucked out. At the same time, the sucked gas is introduced into the filter box through the conduit, and then introduced into the air ring box after being filtered by the filter element. At the same time, an opening is set on the filter box, and with the cooperation of the baffle, the filter element can be easily disassembled and replaced.

[0015] Preferably, two track plates are fixedly installed on the top of the air ring box, and a sliding groove is opened on the track plate. A moving block is slidably connected to the inner wall of the sliding groove, and a support frame is fixedly installed on the moving block. The support frame is fixedly connected to the exhaust fan, and a screw rod is rotatably connected to the inner wall of the sliding groove, and the screw rod is threadedly connected to the moving block.

[0016] The sliding connection between the sliding groove and the moving block can limit the moving block, and the threaded connection between the screw rod and the moving block can adjust the position of the exhaust fan, so that the exhaust fan is close to the cleaning material, making the dust suction more thorough.

[0017] Preferably, the top of the lifting ear is rotatably connected to a transmission gear, and an outer gear ring is fixedly installed on the outer side of the air ring box. The outer gear ring is meshed with four transmission gears, and the transmission gears are threadedly connected to the corresponding support rods.

[0018] The load-bearing ring is positioned by the sliding connection between the lifting lug and the support rod, and the transmission gear is positioned by the meshing of the outer gear ring and the transmission gear, so that the outer gear ring and the four transmission gears can be stably transmitted.

[0019] Preferably, the adjustment mechanism also includes four wedge plates, which are respectively fixedly mounted on the top of the base plate and the bottom of the fixed ring. Two force rods are fixedly mounted on the inner side of the driving ring, and the force rods cooperate with the corresponding two wedge plates. A plurality of protrusions are mounted on the top of the driving ring, and two clamps are fixedly mounted on the inner side of the air ring box, and the clamps cooperate with the protrusions.

[0020] The wedge plate cooperates with the force-bearing rod so that when the air ring box drives the force-bearing rod to move to the wedge plate position, the inclined surface of the wedge plate squeezes the force-bearing rod, forcing it to rotate in the opposite direction. The force-bearing rod drives the corner elbow to rotate through the spring, so that the corner elbow drives the air nozzle to rotate to the other side. At the same time, the engagement limit of the clamping head and the protruding head can limit the angle of the driving ring, so that when the driving ring is not under force, the corner elbow can be positioned by the spring, thereby making the wind force discharged from the corner elbow and the air nozzle push the air ring box to rotate in the opposite direction.

[0021] Preferably, the convex head side cleaning mechanism further includes four infrared sensors, which are symmetrically fixedly mounted on the inner side of the air ring box, and the infrared sensors are connected to the controller.

[0022] Through the setting of the infrared sensor, the raised surface of the workpiece can be scanned and detected. When the infrared sensor located below detects the raised surface, the controller controls the piston on the cylinder to push the push ring upward, thereby driving the laser head to face obliquely downward, thereby performing laser cleaning on the top side of the raised surface. When the infrared sensor moves out of the raised position, the cylinder is reset under the control of the controller, so that the laser head is in a flat state. When the infrared sensor above detects the raised position, the controller controls the piston of the cylinder to drive the push ring to move in the opposite direction, thereby making the laser head face obliquely upward, thereby performing laser cleaning on the bottom of the raised position. When the infrared sensor moves out of the raised position, the cylinder is reset under the control of the controller.

[0023] Preferably, a U-shaped mounting seat is fixedly installed on the inner side of the air ring box, and a mounting plate is rotatably connected to the inner side of the U-shaped mounting seat. The laser head is fixedly connected to the mounting plate, and two racks are fixedly installed on the top of the push ring. A driven gear is fixedly installed on the mounting plate, and the driven gear and the corresponding rack are engaged with each other. An air guide cylinder is provided on the outer side of the laser head, and one end of the air guide cylinder is opened, and a plurality of heat sinks are installed in a ring shape on the laser head, and the heat sink passes through the air guide cylinder. An air pipe is installed on the air guide cylinder, and one end of the air pipe is connected to the air ring box.

[0024] The moving push ring pushes the rack to move, and the rack engages with the driven gear to drive the mounting plate and the laser head to change their angles. The gas in the air ring box is introduced into the air guide cylinder through the air pipe and dispersed and discharged through multiple heat sinks, thereby quickly dissipating the heat of the laser head through the heat sink. At the same time, it can also directly act on the contaminants removed by the laser to clean the contaminants.

[0025] Preferably, a positioning box is installed on one side of the U-shaped mounting seat, the positioning box is slidably connected to the rack, and the driven gear and the rack are both located in the positioning box.

[0026] By providing the positioning box, the mutual meshing connection between the driven gear and the rack can be stabilized.

[0027] Preferably, six limit blocks are fixedly installed on the outer side of the air ring box, and an annular limit groove is opened on the inner side of the load-bearing ring, and the six limit blocks are slidably installed in the annular limit groove.

[0028] The limit block is connected to the annular limit groove by sliding, so that the bearing ring can position the air ring box, so that the air ring box can rotate stably on the bearing ring. The present invention also proposes a method for using the high-efficiency laser cleaning machine, which is used for the high-efficiency laser cleaning machine proposed above, including the following steps:

[0029] S1: Place the workpiece material to be cleaned on the placement plate, perform laser cleaning through the laser head in the air ring box, and start the exhaust fan. The exhaust fan sucks the dust generated during laser cleaning, and at the same time, the sucked gas is introduced into the filter box through the conduit, and then introduced into the air ring box after being filtered by the filter element. The filter box is provided with an opening, and with the cooperation of the baffle, the filter element can be easily disassembled and replaced. The filtered gas in the air ring box is ejected from the air nozzle through the corner elbow. The angle of the corner elbow is set to make the direction of the air nozzle obliquely upward, and then the air ring box is pushed to rotate under the reaction force of the gas, and the ejected gas can also blow the dust upward to the exhaust fan position, and circulate the suction through the exhaust fan;

[0030] S2: The rotating air ring box drives the outer gear ring to rotate. The outer gear ring engages with the transmission gear, thereby driving the transmission gear to rotate. The transmission gear is connected to the support rod through a thread, thereby driving the lifting lug to move up and down, and then driving the bearing ring and the air ring box to move up and down, thereby driving the laser head up and down to laser clean the material;

[0031] S3: When the air ring box moves upward or downward and the force rod touches the wedge plate, the inclined surface of the wedge plate squeezes the force rod, forcing it to rotate in the opposite direction. The force rod drives the corner elbow to rotate through the spring, so that the corner elbow drives the air nozzle to rotate to the other side. At the same time, the engagement limit of the clamp and the convex head can limit the angle of the drive ring, so that when the drive ring is not under force, it can support and position the corner elbow through the spring, and then the wind force discharged from the corner elbow and the air nozzle pushes the air ring box to rotate in the opposite direction, so that the laser head also rotates, thereby performing all-round laser cleaning on the workpiece material;

[0032] S4: When the air ring box drives the infrared sensor to move to the raised position of the workpiece material, it can scan and detect the raised surface of the workpiece. When the infrared sensor located below detects the raised surface, the controller controls the piston on the cylinder to push the push ring upward, and the moving push ring drives the rack to move. The rack engages with the driven gear, thereby driving the mounting plate and the laser head to change the angle, thereby driving the laser head to face obliquely downward, and performing laser cleaning on the top side of the protrusion. When the infrared sensor moves out of the raised position, the cylinder is reset under the control of the controller, so that the laser head is in a straight state. When the upper infrared sensor detects the raised position, the controller controls the piston of the cylinder to drive the push ring to move in the opposite direction, thereby making the laser head face obliquely upward, thereby performing laser cleaning on the bottom of the raised position. When the infrared sensor moves out of the raised position, the cylinder is reset under the control of the controller.

[0033] In summary, the technical effects and advantages of the present invention are as follows:

[0034] 1. Integrated multi-mechanism linkage: The drive mechanism, direction adjustment mechanism, and convex head side cleaning mechanism are integrated into one, and each mechanism works in coordination. For example, the drive mechanism rotates the air ring box while simultaneously driving the load-bearing ring to move up and down, achieving vertical cleaning of the laser head. The ingenious coordination of the various mechanisms achieves all-round cleaning, which is different from traditional single-function laser cleaning equipment.

[0035] 2. Unique air ring box structure: The inner side of the air ring box rotates to connect the laser head, corner elbow, etc., and the outer side cooperates with the transmission gear and external gear ring. It is connected to the load-bearing ring through the limit block and can rotate stably. This structure ensures that its own rotation can achieve circumferential cleaning, and can achieve axial cleaning through transmission. It has a compact structure and diverse functions.

[0036] 3. Dust treatment and airflow assistance: The dust suction and filtration system is composed of exhaust fans, filter boxes, filter elements, etc. The dust generated by cleaning is sucked and filtered, and the gas is ejected from the air nozzle, which not only purifies the environment but also uses airflow to assist cleaning. It can also use the reaction force of the airflow to drive the air ring box to rotate, achieving multiple goals at one stroke.

[0037] 4. Automatic adaptation to convex head cleaning: Utilize infrared sensors to detect workpiece protrusions, and coordinate with cylinders, push rings, racks, driven gears, etc. to automatically adjust the angle of the laser head for targeted cleaning of the top and bottom of the protruding parts, effectively solving the problem of complex surface cleaning and improving cleaning effects and applicability.

[0038] 5. Intelligent direction adjustment control: The wedge plate, force rod, spring, drive ring, clamp, and convex head in the direction adjustment mechanism cooperate to automatically adjust the corner elbow and the direction of the air ring box when it moves, so as to achieve continuous rotation of the air ring box and all-round cleaning of the laser head without frequent manual intervention, thereby improving the degree of cleaning automation.

[0039] 6. Refined position adjustment: The exhaust fan position adjustment structure is composed of track plate, sliding groove, moving block, screw rod, etc., which can accurately adjust the exhaust fan position according to cleaning needs, making dust suction more thorough and improving equipment performance.

[0062] The present invention also provides a method for using a high-efficiency laser cleaning machine, which is used for the high-efficiency laser cleaning machine proposed above, comprising the following steps:

[0063] S1: Place the workpiece material to be cleaned on the placement plate 15, perform laser cleaning through the laser head 83 in the air ring box 5, and start the exhaust fan 61. The exhaust fan 61 sucks the dust generated during laser cleaning, and at the same time, the sucked gas is introduced into the filter box 62 through the conduit, and then introduced into the air ring box 5 after being filtered by the filter element 63.

The transmission gear 10 is threadedly connected to the support rod 2, thereby driving the lifting lug 9 to move up and down, and then driving the bearing ring 4 and the air ring box 5 to move up and down, thereby driving the laser head 83 to move up and down to perform laser cleaning on the material;

[0065] S3: When the air ring box 5 moves upward or downward and the force rod 75 touches the wedge plate 76, the inclined surface of the wedge plate 76 squeezes the force rod 75, forcing it to rotate in the opposite direction. The force rod 75 drives the corner elbow 65 to rotate through the spring 74, so that the corner elbow 65 drives the air nozzle 66 to rotate to the other side. At the same time, the engagement limit of the clamping head 72 and the protruding head 73 is used to limit the angle of the driving ring 71, so that the driving ring 71 can support and position the corner elbow 65 through the spring 74 when it is not under force, thereby making the wind force discharged from the corner elbow 65 and the air nozzle 66 push the air ring box 5 to rotate in the opposite direction, so that the laser head 83 also rotates, thereby performing all-round laser cleaning on the workpiece material;

[0066] S4: When the air ring box 5 drives the infrared sensor 88 to move to the raised position of the workpiece material, it can scan and detect the raised surface of the workpiece. When the infrared sensor 88 located below detects the raised surface, the controller 14 controls the piston on the cylinder 84 to push the push ring 87 upward. The moving push ring 87 pushes the rack 86 to move. The rack 86 is engaged with the driven gear 85, thereby driving the mounting plate 82 and the laser head 83 to change the angle, thereby driving the laser head 83 to face obliquely downward, and performing laser cleaning on the top side of the protrusion. When the infrared sensor 88 moves out of the raised position, the cylinder 84 is reset under the control of the controller 14, so that the laser head 83 is in a straight state. When the upper infrared sensor 88 detects the raised position, the controller 14 controls the piston of the cylinder 84 to drive the push ring 87 to move in the opposite direction, thereby making the laser head 83 face obliquely upward, thereby performing laser cleaning on the bottom of the raised position. When the infrared sensor 88 moves out of the raised position, the cylinder 84 is reset under the control of the controller 14.

10. A method for using a high-efficiency laser cleaning machine, used for a high-efficiency laser cleaning machine according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: Place the workpiece material to be cleaned on the placement plate (15), perform laser cleaning through the laser head (83) in the air ring box (5), and start the exhaust fan (61). The exhaust fan (61) sucks the dust generated during the laser cleaning, and the sucked gas is introduced into the filter box (62) through the conduit, and then introduced into the air ring box (5) after being filtered by the filter element (63). The filter box (62) is provided with an opening, and with the cooperation of the baffle (64), the filter element (63) can be easily disassembled and replaced. The filtered gas in the air ring box (5) is ejected through the corner bend pipe (65) and the air nozzle (66). The corner of the corner bend pipe (65) is set so that the direction of the air nozzle (66) is inclined upward, and then the air ring box (5) is pushed to rotate under the reaction force of the gas, and the ejected gas can also blow the dust upward to the position of the exhaust fan (61), and circulate and extract through the exhaust fan (61); S2: The rotating air ring box (5) drives the outer gear ring (11) to rotate, and the outer gear ring (11) is engaged with the transmission gear (10), thereby driving the transmission gear (10) to rotate. The transmission gear (10) is connected to the support rod (2) through a thread, thereby driving the lifting lug (9) to move up and down, and then driving the bearing ring (4) and the air ring box (5) to move up and down, thereby driving the laser head (83) to perform laser cleaning on the material; S3: When the air ring box (5) moves upward or downward and the force rod (75) touches the wedge plate (76), the reaction force of the wedge surface of the wedge plate (76) pushes the force rod (75) to rotate in the opposite direction, and the force rod (75) drives the corner bend pipe (65) to rotate through the spring (74), so that the corner bend pipe (65) drives the air nozzle (66) to rotate to the other side, and at the same time, the angle of the drive ring (71) can be limited by the buckle of the clamping head (72) and the convex head (73), so that the drive ring (71) can support and position the corner bend pipe (65) through the spring (74) when it is not under force, and then the wind force discharged by the corner bend pipe (65) and the air nozzle (66) pushes the air ring box (5) to rotate in the opposite direction, so that the laser head (83) also rotates, thereby performing all-round laser cleaning on the workpiece material; S4: When the air ring box (5) drives the infrared sensor (88) to move to the raised position of the workpiece material, the raised surface of the workpiece can be scanned and detected. When the infrared sensor (88) located below detects the raised surface, the piston on the cylinder (84) is controlled by the controller (14) to push the push ring (87) upward. The moving push ring (87) pushes the rack (86) to move. The rack (86) is meshed with the driven gear (85), thereby driving the mounting plate (82) and the laser head (83) to change the angle, thereby driving the laser head (83) to face obliquely downward to the raised surface. The top side of the protrusion is laser cleaned. When the infrared sensor (88) moves out of the protruding position, the cylinder (84) is reset under the control of the controller (14), so that the laser head (83) is in a straight state. When the infrared sensor (88) above detects the protruding position, the controller (14) controls the piston of the cylinder (84) to drive the push ring (87) to move in the opposite direction, thereby making the laser head (83) face obliquely upward, thereby performing laser cleaning on the lower side of the protruding position. When the infrared sensor (88) moves out of the protruding position, the cylinder (84) is reset under the control of the controller (14).
