DETAILED DESCRIPTION

[0045] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with the embodiments.

[0046] Example 1

[0047] The present application provides an automatic following rotating laser cleaning device, which comprises a workbench, a three-axis rotating structure, a laser, an air pipe, a support plate, a scanning camera, a magnetic attraction driving structure, a shielding protection structure, a moving plate, a fine adjustment structure, a blocking plate, a guiding anti-collision structure and a positioning piece. Figures 1 to 7As shown, it comprises: a workbench 1, a three-axis rotating structure 2, a laser 3, an air pipe 4 and an automatic adjustment blocking assembly; the workbench 1 serves as the support frame of the whole laser cleaning device; the three-axis rotating structure 2 is connected to the workbench 1 and is used for multi-azimuth angle adjustment (axial movement along the X-axis, Y-axis and Z-axis and rotation along the Y-axis and Z-axis); the laser 3 is connected to the three-axis rotating structure 2 and is used for emitting a laser beam; the air pipe 4 is connected to the laser 3 and is used for guiding gas; the automatic adjustment blocking assembly comprises: a support plate 51, a scanning camera 52, a magnetic driving structure 53, a shielding protection structure 54, a moving plate 55, a fine adjustment structure 56, a blocking plate 57 and a guiding anti-collision structure 58; the support plate 51 is connected to the laser 3 and is used for mounting and fixing the scanning camera 52, the top end of the support plate 51 is connected to the magnetic driving structure 53 through the shielding protection structure 54, the shielding protection structure 54 is connected to the fine adjustment structure 56 through the moving plate 55, the bottom end of the moving plate 55 and the top end of the support plate 51 are connected to the guiding anti-collision structure 58, the guiding anti-collision structure 58 is used for adjusting the reset efficiency of the moving plate 55, the blocking plate 57 is connected to the fine adjustment structure 56, and the magnetic driving structure 53 and the fine adjustment structure 56 drive the blocking plate 57 to move linearly (along the X-axis) above the support plate 51.

[0048] When encountering complex situations such as changes in groove depth or internal depressions on the workpiece surface, the traditional laser cleaning method is difficult to effectively adjust the width of the linear laser beam, causing over-cleaning problems in the area around the workpiece groove or depression, which not only wastes cleaning materials but also may damage the workpiece surface;

[0049] The device achieves the purpose of adjusting the width of the laser beam through the automatic adjustment blocking assembly. First, the scanning camera 52 performs omnidirectional scanning on the workpiece surface, identifies the characteristics of the grooves and depressions on the workpiece surface, collects surface topography data and transmits it to the control system. Then, the magnetic driving structure 53 drives the moving plate 55 to preliminarily move the blocking plate 57 according to the control instruction, and coarsely adjusts the width of the laser beam. Next, the fine adjustment structure 56 plays a role in finely adjusting the position of the blocking plate 57, realizing the constraint of the width of the laser beam. In the whole cleaning process, the width of the laser beam can match the needs of the workpiece surface, effectively preventing over-cleaning or under-cleaning phenomena, significantly improving the quality and efficiency of laser cleaning, ensuring uniform cleaning effect of the workpiece surface and meeting the cleaning requirements of various complex workpieces;

[0050] In the above process, although the blocking plate 57 can block the laser beam, the blocking plate 57 is damaged after blocking the laser beam, which reduces the service life of the blocking plate 57. Therefore, the guide anti-collision structure 58 is used to make the blocking plate 57 tilt during horizontal movement, so that the blocking plate 57 blocks the laser beam at different positions on the surface, preventing the same part from blocking the laser beam for a long time and causing damage, thereby effectively improving the service life of the blocking plate 57.

[0051] In use, the workpiece is placed on the surface of the workbench 1, and the air pipe 4 is connected to the gas source (the gas is pumped out of the external environment and discharged along the air pipe 4, which is a prior art and will not be described in detail here). At this time, the gas is sprayed on the surface of the workpiece along the air pipe 4, and the visual linkage module obtains visual information through the scanning camera 52. After the data is analyzed by the central processor, the three-axis rotating structure 2 and the magnetic driving structure 53 are driven to operate by the central processor, so as to adjust the angle and width of the laser beam. The three-axis rotating structure 2 makes the laser 3 move along the X-axis, Y-axis and Z-axis, and can also make the laser 3 rotate along the Y-axis and Z-axis, so that the laser can automatically follow the surface of the workpiece 3. This achieves comprehensive cleaning of the surface of the workpiece, and realizes the purpose of cleaning the uneven workpiece through the automatic zoom function (automatic zoom and automatic following are prior arts and will not be described in detail here). When the cleaning part is too small and the laser beam is too wide, the magnetic driving structure 53 is connected to the power supply and operates at this time. The magnetic driving structure 53 drives the moving plate 55 to move when it operates. The moving plate 55 slides in the support plate 51 through the guide anti-collision structure 58 when it moves, so that the moving plate 55 moves axially and tilts in the support plate 51, changes the position of the moving plate 55 at the center point of the top of the support plate 51, and then starts the fine adjustment structure 56. The fine adjustment structure 56 drives the blocking plate 57 to move when it operates, so as to realize the constraint of the width of the laser beam.

[0052] Specifically, the top end of the workbench 1 is provided with a three-axis rotating structure 2, the output end of the three-axis rotating structure 2 is provided with a laser 3, the outer side of the laser 3 is embeddedly provided with an air pipe 4, the bottom end of the laser 3 is symmetrically provided with a supporting plate 51, the bottom end of the supporting plate 51 is embeddedly provided with a scanning camera 52, the top end of the supporting plate 51 is fixedly provided with a shielding protection structure 54, the shielding protection structure 54 is fixedly provided with a magnetic suction driving structure 53 inside, the same moving plate 55 is connected between the magnetic suction driving structure 53 and one end of the shielding protection structure 54, the moving plate 55 is internally provided with a fine adjustment structure 56, one end of the fine adjustment structure 56 is provided with a blocking plate 57, the bottom end of the moving plate 55 is fixedly provided with a guide anti-collision structure 58, a rounded corner is formed at one end of the blocking plate 57, a shape memory alloy self-repairing coating is sprayed on the top end of the blocking plate 57, the shape memory alloy self-repairing coating is made of nickel-titanium alloy powder, and the blocking plate 57 can be self-repaired through the surface of the blocking plate 57, so that the service life of the blocking plate 57 is improved, the scanning camera 52 and the three-axis rotating structure 2 are connected through a visual linkage module, and visual acquisition and mechanical adjustment are associated (this mode belongs to the prior art, and will not be described in detail here), the visual linkage module acquires visual information through the scanning camera 52, data is analyzed by a central processing unit, and the three-axis rotating structure 2 and the magnetic suction driving structure 53 are driven to adjust the angle and width of the laser beam (which belongs to the prior art, and will not be described in detail here), and finally closed-loop feedback is realized through an encoder and a displacement sensor (the encoder and the displacement sensor belong to the prior art, and will not be described in detail here), and the top end of the supporting plate 51 is symmetrically integrally formed with a positioning piece 59, which is used to limit the position of the moving plate 55.

[0053] As shown in Figure 4 and Figure 6 The guide anti-collision structure 58 comprises a stand 581, a bearing 582, a rotating piece 583, an extrusion piece 584, an air inlet piece 585 and an exhaust groove 586; the stand 581 is connected below the moving plate 55; the bearing 582 is sleeved outside the stand 581; the rotating piece 583 is sleeved outside the bearing 582 and rotates outside the stand 581 through the bearing 582; the extrusion piece 584 is connected to the stand 581; the air inlet piece 585 is inserted into the stand 581; and the exhaust groove 586 is arranged outside the stand 581 and above the air inlet piece 585.

[0054] After the magnetic suction driving structure 53 is powered off, the moving plate 55 will be reset due to the internal magnetic suction mechanism, which is easy to cause collision between components, and further causes displacement of internal precision components of the laser 3, affecting the emission accuracy of the laser beam and the stability of the equipment. In order to solve this problem, the guide anti-collision structure 58 is designed in the device, which reduces the strength of the rigid collision.

[0055] When the magnetic attraction driving structure 53 is powered off to trigger the reset of the moving plate 55, the moving plate 55 drives the column 581 to move, the column 581 promotes the rotation piece 583 to move inside the inclined groove, and the rotation piece 583 rotates under the support of the friction and the bearing 582. At this time, the rotation of the rotation piece 583 causes the external gas to enter the inside of the air inlet piece 585. Since the shape of the air inlet piece 585 is Y-shaped, the air inlet piece 585 is composed of two air inlets and one air outlet at this time, and the diameter of the air outlet is smaller than that of the air inlet (as shown in Figure 6 The gas converges and accelerates inside the air inlet piece 585, and the accelerated gas enters the inside of the rotation piece 583 and the bottom of the extrusion piece 584. At this time, the airflow pushes the extrusion piece 584 to rise along the axis of the column 581, so that the extrusion piece 584 is tightly attached to the inner wall of the rotation piece 583. As the contact pressure between the extrusion piece 584 and the rotation piece 583 increases, the friction between them increases, the rotation speed of the rotation piece 583 is inhibited, the reset speed is reduced, the rigid collision in the magnetic attraction driving structure 53 is avoided, and the blocked gas at the bottom of the extrusion piece 584 is discharged through the exhaust groove 586, completing a complete buffering process.

[0056] Specifically, the moving plate 55 is integrally formed with the column 581 at the bottom end, the bearing 582 is installed on the outer surface of the bottom of the column 581 through interference fit, the rotation piece 583 is installed on the outer side of the bearing 582 through interference fit, the extrusion piece 584 is slidingly connected inside the column 581, the sliding groove is formed in the middle of the column 581, the extrusion piece 584 is composed of a circular ring and a rectangular strip, the rectangular strip is slidingly connected inside the sliding groove, the inner wall of the circular ring and the outer side of the column 581 are attached to each other, the outer surface of the circular ring is provided with a chamfer at the edge, the inner wall of the rotation piece 583 is provided with a chamfer (as shown in Figure 6 The outer surface of the rotation piece 583 is embedded with a plurality of air inlet pieces 585, the air outlet end of the air inlet piece 585 is located at the bottom end of the extrusion piece 584, the exhaust groove 586 is formed at the top end of the air inlet piece 585, the shape of the air inlet piece 585 is Y-shaped, and the air inlet piece 585 belongs to a Y-shaped conduit (as shown in Figure 6 The diameter of the air inlet piece 585 is greater than that of the exhaust groove 586, the air inlet efficiency of the air inlet piece 585 is greater than that of the exhaust groove 586, the air inlet speed is greater than the air outlet speed at this time, so that the extrusion piece 584 can be driven to rise).

[0057] As shown in Figure 3 and Figure 5 The fine adjustment structure 56 includes a driving piece 561 and a limiting piece 562. The driving piece 561 is connected to the moving plate 55 and the blocking plate 57. The limiting piece 562 penetrates the moving plate 55 and is connected to the blocking plate 57. The driving piece 561 drives the moving plate 55 and the blocking plate 57 to move away from or close to each other.

[0058] In use, the blocking plate 57 is driven to move by the driving member 561, and the blocking plate 57 moves on the top end of the moving plate 55 by the limiting member 562, so that the position of the blocking plate 57 is fine-tuned, and the limiting is kept during the fine-tuning, so that the purpose of stable axial movement is achieved.

[0059] Specifically, the moving plate 55 is provided with the driving member 561 on one end surface, and the moving plate 55 is provided with a circular hole symmetrically in the inside, the circular hole is slidably connected with the limiting member 562, and the limiting member 562 and the driving member 561 are connected with the blocking plate 57.

[0060] In the application, the driving member 561 specifically belongs to a linear driving structure, and specifically belongs to a piezoelectric ceramic, and the limiting member 562 belongs to a linear limiting structure, and specifically belongs to a limiting rod.

[0061] As shown in Figure 3 and Figure 4 , the shielding protection structure 54 comprises a shielding layer outer cover 541 and a shielding layer inner cover 542, the shielding layer outer cover 541 is connected to the laser 3, the shielding layer inner cover 542 is connected to the shielding layer outer cover 541 and the moving plate 55 at both ends respectively, a limiting groove is formed in the inner side of the shielding layer outer cover 541, a protrusion is integrally formed on the outer side of the shielding layer inner cover 542, and the inner wall of the shielding layer outer cover 541 and the outer side of the shielding layer inner cover 542 are mutually attached.

[0062] Since the magnetic driving structure 53 generates magnetism during operation, the magnetism is blocked by the shielding protection structure 54 at this time, so as to prevent the magnetism from interfering with the inside of the laser 3.

[0063] In use, the shielding layer inner cover 542 moves along the inside of the shielding layer outer cover 541.

[0064] In the application, the shielding layer outer cover 541 and the shielding layer inner cover 542 belong to a magnetic shielding structure, and specifically belong to engineering plastics, such as magnetic polyvinyl chloride and magnetic polyethylene.

[0065] Specifically, the shielding layer inner cover 542 is slidably connected to the inside of the shielding layer outer cover 541, the outer side of the shielding layer outer cover 541 is fixedly connected to the top end of the support plate 51, and the inside of the shielding layer outer cover 541 is fixedly connected to the outer side of the suction accessory 533.

[0066] As shown in Figure 3 and Figure 4 , the magnetic driving structure 53 comprises a fixing member 531, a magnetic attraction member 532, a suction accessory 533 and a sliding block 534, the fixing member 531 is connected to the inside of the shielding layer outer cover 541, the magnetic attraction member 532 is connected to the fixing member 531, the suction accessory 533 is connected to the inside of the shielding layer inner cover 542, the magnetic attraction member 532 drives the suction accessory 533 to move away from the fixing member 531, and the sliding block 534 is connected to the suction accessory 533 and connected to the inside of the moving plate 55.

[0067] When in use, the magnetic suction component 532 generates electromagnetic fields when energized. At this time, the magnetic poles on the opposite side of the suction component 533 are opposite, causing the magnetic drive to move the suction component 533 away from the fixing component 531. At the same time, the slider 534 drives the moving plate 55 to move. At this time, the moving plate 55 moves obliquely under the action of the guide anti-collision structure 58, causing the moving plate 55 to move along the outside of the slider 534, thereby causing the moving plate 55 to be displaced obliquely. At the same time, when the magnetic suction component 532 is de-energized, the fixing component 531 and the suction component 533 will stick together due to the attraction force.

[0068] Inside the outer shielding cover 541, a fastener 531 is fixedly installed. A magnetic attractor 532 is fixedly installed on the inner wall of the fastener 531. Inside the inner shielding cover 542, an adsorption component 533 is fixedly installed. A slider 534 is fixedly installed at one end of the adsorption component 533. The slider 534 is an insulator made of engineering plastic and is I-shaped (e.g., ...). Figure 4 As shown), slider 534 is slidably connected to the inside of movable plate 55. A guide groove is provided inside movable plate 55 corresponding to the outer side of slider 534, allowing slider 534 to move within movable plate 55 via the guide groove (e.g., ...). Figure 3 (As shown).

[0069] In this application, the magnetic attracting component 532 is an electromagnet, the fixing component 531 is an iron block, and the adsorption component 533 is a permanent magnet.

[0070] Working principle: When in use, the workpiece is placed on the surface of the worktable 1 and fixed. At this time, the air pipe 4 is connected to the air source. The air source sprays along the air pipe 4 onto the surface of the workpiece, using gas to clean the surface of the workpiece and prevent the debris after cleaning from accumulating on the surface of the workpiece and affecting the viewing of the workpiece. At the same time, the scanning camera 52 scans the surface of the workpiece. After information processing, the vision linkage module drives the three-axis rotation structure 2 and the magnetic drive structure 53 to run. When the three-axis rotation structure 2 is running, it adjusts the laser beam angle and makes the laser 3 move along the three axes of the spatial coordinate system on the X, Y and Z axes. At the same time, it can make the laser 3 rotate along the Y and Z axes, so that the laser beam emitted by the laser 1 can automatically follow the complex curved surface of the workpiece.

[0071] Meanwhile, the magnetic drive structure 53 runs, the magnetic attraction 532 power generation at this time, and with the opposite pole of the suction member 533, resulting in magnetic drive suction member 533 and fixed between the repulsion of the same sex and far away, the suction member 533 moving with the slider 534 moves, at this time the slider 534 drive moving plate 55 moves, moving plate 55 moving with the column 581 moves, at this time the column 581 with the rotating member 583 along the guide groove guide effect moves, and through the friction between the support plate 51 makes the rotating member 583 in the guide groove inside rotation, at this time through the guide groove guide effect makes the moving plate 55 along the support plate 51 top end oblique displacement, and at the same time, the moving plate 55 oblique displacement through the guide groove outside the slider 534 horizontal movement, so that the moving plate 55 realizes the composite movement of oblique displacement and horizontal displacement (axial movement, the moving plate 55 in the support plate 51 top end position changes);

[0072] And, the suction member 533 and the magnetic attraction 532 away from this time, the shielding layer cover 542 along the shielding layer cover 541 inside the limit groove sliding, then the drive member 561 connected to the power supply and run, at this time through the drive member 561 drive barrier plate 57 moves, the barrier plate 57 moves through the limit of the limit piece 562 under the movement, so as to achieve the position of the barrier plate 57 fine tuning, and in fine tuning to keep stable purpose, at this time through the fine tuning of the barrier plate 57 to the laser beam, so that the width of the laser beam changes;

[0073] Finally, when the magnetic drive structure 53 power off, the magnetic attraction 53 and the suction member 533 due to the principle of magnetic attraction trigger moving plate 55 fast reset, the moving plate 55 moving with the column 581 moves, prompting the rotating member 583 in the guide groove moves, and through the friction force under the support of the bearing 582 rotates, at this time, the rotating member 583 rotates to make the external gas into the air inlet member 585 inside, and because the shape of the air inlet member 585 is Y type, at this time the air inlet member 585 consists of two air inlet and one air outlet, and the diameter of the air outlet is smaller than the diameter of the air inlet, resulting in the gas into the air inlet member 585 gathering to accelerate, the accelerated gas into the rotating member 583 inside and into the extrusion member 584 bottom, high speed airflow pushes the extrusion member 584 along the column 581 axial rising, make it with the rotating member 583 inner wall closely, with the extrusion member 584 and the rotating member 583 contact pressure increases, the friction between the two increases, effectively increases the rotating member 583 rotation resistance, inhibit the rotating speed of the rotating member 583, reduce the reset speed, thereby reducing the strength of the rigid collision in the magnetic drive structure 53, and the gas through the exhaust groove 586 after the air inlet member 584 bottom barrier, complete a complete buffering process.

[0074] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them.
