Description

Technical Field

[0001] This disclosure relates to the field of laser processing technology, and in particular to a laser marking device for power station signage. Background Technology

[0002] As a core component for guidance, warning, and information disclosure, the marking quality of refueling station signs directly affects the safety and visual recognition of use. They also need to adapt to the complex outdoor environment of refueling stations (high and low temperatures, wind and rain, corrosive gases), requiring extremely high clarity, wear resistance, and corrosion resistance of the markings.

[0003] When processing signs and labels of different sizes and dimensions, conventional laser marking equipment requires workers to repeatedly adjust the installation position and marking height of the laser marking device when dealing with signs and labels of varying lengths, widths, and thicknesses. Furthermore, after laser marking, a large amount of dust, debris, slag particles, and various impurities remain inside the marking grooves. Since signs and labels are usually placed horizontally with their faces upwards during processing, conventional dust blowers can only remove surface dust due to structural orientation limitations. Airflow cannot penetrate deep into the grooves to create effective convection, and the retention of impurities can easily cause corrosion and blockage of the marking lines, affecting the aesthetics and lifespan of the finished product. Subsequent manual cleaning further increases the workload and labor costs. Summary of the Invention

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. This invention achieves rapid positioning of signs of different specifications through the cooperation of docking components and laser marking devices. When the moving frame moves, the gear and rack mesh, driving the first docking rod and the second docking rod to rotate synchronously. Through threaded transmission, the first docking block and the second docking block are moved to the edge of the sign. Then, the electric telescopic rod pushes the guide block, driving the laser marking device to the marking position. This eliminates the need for staff to repeatedly adjust the horizontal and vertical position and height of the laser marking device for signs of different length and width specifications, reducing adjustment time, improving the continuity and efficiency of marking operations, and reducing the difficulty of manual operation. 2. This invention uses a flipping component to rotate the placement plate 180° so that the sign faces downwards. The nozzle of the air blowing strip can be directly aligned with the marking groove, allowing the airflow to penetrate deep into the groove and form convection, thoroughly blowing out residual dust, slag, and other impurities. At the same time, the dust collector quickly sucks the impurities into the dust collection box through the suction port, achieving integrated "air blowing-dust suction" cleaning. This avoids the corrosion of the sign and blockage of the marking lines caused by the retention of impurities, effectively improving the finished appearance of the energy station sign and extending the service life of the sign. 3. This invention utilizes a sliding dust-collecting plate along a guide frame for loading and unloading, enabling simultaneous cleaning and removal of marked labels and conveying and loading of unmarked labels. The flipping component can rotate the placement plate 180°, switching between the marking surface and the loading / unloading surface. The flipping action is linked to the movement of the moving frame, requiring no additional power and simplifying the operation. Furthermore, the flipping of the placement plate, combined with the locking mechanism of the electric locking push rod and locking pin, ensures the stability and safety of the flipping process.

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1-13As shown in the figure, this disclosure proposes a laser marking device for refueling station signs, including a marking table 1, a placement plate 2 rotatably mounted on the marking table 1, a movable frame 3 slidably mounted above the placement plate 2 on the marking table 1, a laser marking device 4 slidably mounted on the movable frame 3, a flipping component 5 cooperating with the movable frame 3 between the marking table 1 and the placement plate 2, a docking component 6 between the laser marking device 4 and the movable frame 3, and a loading / unloading dust extraction plate 7 slidably mounted below the placement plate 2 on the marking table 1. Guide frames 8 are fixedly connected to both sides of the fixed legs below the engraving table 1. A placement groove 9 is formed downwards on the upper side of the loading / unloading dust collection plate 7. At least two first cylinders 10 are fixedly installed at the bottom of the loading / unloading dust collection plate 7. Each first cylinder 10 has a telescopic shaft that passes through one end of the loading / unloading dust collection plate 7 located within the placement groove 9 and is fixedly connected to a support plate 11. The two sides of the loading / unloading dust collection plate 7 are slidably fitted onto the inner walls of the guide frames 8. The support plate 11 is located within a groove on the bottom wall of the placement groove 9. A dust collection box 12 is fixedly installed at the bottom of the loading / unloading dust collection plate 7. The bottom wall of the placement trough 9 has a downward-facing suction port 13 that communicates with the dust collection box 12. An air blowing strip 14 is fixedly connected to the bottom wall of the placement trough 9. A dust collector 16 is fixedly installed at the bottom of the loading / unloading dust collection plate 7. Several nozzles 15 are fixedly connected to the air blowing strip 14. The air inlet of the dust collector 16 is connected to the dust collection box 12 and the suction port 13 via a pipe. The air outlet of the dust collector 16 is connected to the air blowing strip 14 via a pipe. Right-angle positioning frames 17 are fixedly connected to both the upper and lower surfaces of the placement plate 2. A second cylinder 18 is fixedly installed in the transverse grooves on both the upper and lower surfaces of the placement plate 2. The end of the telescopic shaft of the second cylinder 18 is fixedly connected to a transverse clamping plate 19 that slides on the placement plate 2. A third cylinder 20 is fixedly installed in the longitudinal grooves on both the upper and lower surfaces of the placement plate 2. The end of the telescopic shaft of the third cylinder 20 is fixedly connected to a longitudinal clamping plate 21 that slides on the placement plate 2. The transverse clamping plate 19 is parallel to the longer side of the right-angle positioning frame 17, and the longitudinal clamping plate 21 is parallel to the shorter side of the right-angle positioning frame 17.

[0021] Understandably, activating the first cylinder 10 at the bottom of the loading / unloading dust extraction plate 7 causes the telescopic shaft of the first cylinder 10 to push the tray 11 upward, lifting the unmarked label in the placement slot 9 and placing it within the right-angle positioning frame 17 on the bottom surface of the placement plate 2. Subsequently, activating the third cylinder 20 in the longitudinal groove and the second cylinder 18 in the transverse groove on the bottom surface of the placement plate 2 causes the third cylinder 20 to drive the longitudinal clamping plate 21 and the second cylinder 18 to drive the transverse clamping plate 19 to move synchronously, cooperating with the right-angle positioning frame 17 to complete the longitudinal and transverse positioning and clamping of the unmarked label, ensuring that the label does not shift during the marking process. After clamping, the loading and unloading dust suction plate 7 is pulled out along the guide frame 8 to prepare for the flipping of the placement plate 2. After flipping, the unloaded loading and unloading dust suction plate 7 is pushed back under the placement plate 2, and the dust collector 16 is started. The dust collector 16 draws the dust collection box 12 to a negative pressure state through the pipe. At the same time, the air outlet of the dust collector 16 supplies air to the air blowing strip 14 through the pipe. Several nozzles 15 on the air blowing strip 14 blow air onto the surface of the marked nameplate and the marked groove, blowing out the dust, debris, slag particles and other impurities remaining in the groove. After the impurities are blown out, they are sucked into the dust collection box 12 through the dust suction port 13 on the bottom wall of the placement groove 9, completing the collection and cleaning of impurities and avoiding impurity retention.

[0022] In some embodiments, the flipping assembly 5 includes a rotating rod 501 fixedly connected to the middle of both sides of the placement plate 2. A cylindrical cam 502 is fixedly connected to the end of one of the rotating rods 501 on the placement plate 2. A slide rod 503 is slidably fitted on the marking stage 1.

[0023] Understandably, after the label is marked, the servo motor 26 drives the first screw 27 to rotate in the opposite direction, causing the moving frame 3 to return to the front end of the placement plate 2, and then continues to move away from the placement plate 2. At this time, the electric locking push rod 510 on one side of the marking table 1 is activated, causing the locking pin 511 to disengage from the locking groove 512 of the placement plate 2, thus releasing the lock on the placement plate 2. As the moving frame 3 continues to move, the overlapping block 508 on its lower side abuts against the displacement block 504, causing the slide rod 503 to slide backward along the first slide groove 506, compressing the first spring 507; the guide post 505 at the bottom of the displacement block 504 slides in conjunction with the groove on the periphery of the cylindrical cam 502 (two semi-circular spiral grooves connected by straight grooves), driving the cylindrical cam 502 and the rotating rod 501 to rotate 180°, thereby causing the placement plate 2 to rotate 180°, so that the marked label is facing down and aligned with the loading and unloading dust collection plate 7 below.

[0024] In some embodiments, the docking assembly 6 includes a first docking rod 601 rotatably engaged with the movable frame 3, and a second docking rod 602 rotatably engaged with the side of the marking stage 1.

The laser marking device 4 is elastically slidably mounted on one side of the guide block 23. A high-low undulating wheel 25 is fixedly mounted on the front side of the laser marking device 4. A servo motor 26 is fixedly mounted on one side of the marking stage 1. The output shaft of the servo motor 26 is fixedly connected to a first screw 27. An electric telescopic rod 29 is fixedly connected to one side of the first docking block 603. The second docking block 604 cooperates with the longitudinal clamping plate 21. A threaded groove 28 that is threaded to the first screw 27 is opened through one side of the moving frame 3. The end of the telescopic shaft of the electric telescopic rod 29 overlaps with one side of the guide block 23. A second spring 30 is fixedly connected between one side of the first docking rod 601 and the inner wall of the guide groove 22. A first threaded section 607 is provided on the first docking rod 601. A first connecting block 608 that is threadedly engaged with the first threaded section 607 is fixedly connected to one side of the first docking block 603. A second threaded section 609 is provided on the second docking rod 602. A second connecting block 610 that is threadedly engaged with the second threaded section 609 is fixedly connected to one side of the second docking block 604. A connecting sleeve 611 is slidably fitted around the periphery of the second docking rod 602. A right-angle block 612 is fixedly connected around the periphery of the connecting sleeve 611. One end of the first docking rod 601 is connected to the right-angle block 612. One side of the 12 rotates and engages, and one end of the first docking rod 601 is fixedly connected to the periphery of the connecting sleeve 611 with bevel gears 613. The two bevel gears 613 mesh with each other. A connecting ring plate 614 is fixedly connected to the lower part of the moving frame 3. The hollow groove of the connecting ring plate 614 is fitted around the periphery of the first docking rod 601 and a ratchet ring 615 is fixedly connected to its edge. A gear 616 is fixedly connected to the periphery of the ratchet ring 615. A rack 617 is fixedly connected to the upper side of the marking stage 1. A fixed disk 618 located inside the ratchet ring 615 is fixedly connected to the periphery of the first docking rod 601. A ratchet tooth 619 is rotatably engaged on one side of the fixed disk 618.In this configuration, the gear 616 meshes with the rack 617; a third torsion spring is provided at the rotating part of the ratchet 619 and the fixed disk 618; the ratchet 619 engages with the ratchet groove on the inner wall of the ratchet ring 615; a disk 620 with multiple slots on its circumference is fixedly connected to the periphery of the first docking rod 601; a positioning frame 621 is elastically slidably fitted on one side of the moving frame 3; a beveled block 622 is fixedly connected to one side of the positioning frame 621; and a protrusion 623 is fixedly connected to the marking stage 1. The beveled edge of the beveled block 622 engages with the slot of the disk 620, and the bottom end of the longitudinal edge of the positioning frame 621 engages with the protrusion 623.

[0025] It should be noted that when the servo motor 26 on one side of the marking stage 1 is started, the output shaft of the servo motor 26 drives the first screw 27 to rotate. Since the threaded groove 28 on one side of the moving frame 3 is threadedly engaged with the first screw 27, the rotation of the first screw 27 drives the moving frame 3 to slide along the top of the marking stage 1, thereby adjusting the longitudinal position of the laser marking device 4. Meanwhile, the laser marking device 4 on the moving frame 3 can slide laterally along the moving frame 3 to further adjust the lateral marking position. When the moving frame 3 moves, the gear 616 meshes with the rack 617 on the marking table 1 and rotates. Through the meshing of the ratchet ring 615 and the ratchet 619, the first docking rod 601 is driven to rotate. The first docking rod 601 meshes with the bevel gear 613 and drives the second docking rod 602 to rotate synchronously. The first docking rod 601 and the second docking rod 602 drive the first docking block 603 and the second docking block 604 to move to the edge of the sign through the first threaded section 607 and the second threaded section 609, respectively. The first docking block 603 pushes the guide block 23 to slide along the guide groove 22 through the electric telescopic rod 29, compressing the second spring 30, and finally drives the laser marking device 4 to move precisely to the marking position of the sign. The laser marking device 4 is started to complete the laser marking operation on the sign.

[0026] Working principle: When using the device, firstly, the operator places the unmarked label in the placement groove 9 of the loading and unloading dust collection plate 7, pushes the loading and unloading dust collection plate 7 to slide along the guide frame 8, and moves it to the hollow area in the middle of the marking table 1, below the placement plate 2. Then, the first cylinder 10 at the bottom of the loading and unloading dust collection plate 7 is activated. The telescopic shaft of the first cylinder 10 pushes the support plate 11 upward, lifting the unmarked label in the placement groove 9 and placing it into the right angle positioning frame 17 on the bottom surface of the placement plate 2. Next, the third cylinder 20 in the longitudinal groove and the second cylinder 18 in the transverse groove on the bottom surface of the placement plate 2 are activated. The third cylinder 20 drives the longitudinal clamping plate 21 and the second cylinder 18 drives the transverse clamping plate 19 to move synchronously, cooperating with the right angle positioning frame 17 to complete the longitudinal and transverse positioning and clamping of the unmarked label, ensuring that the label does not shift during the marking process. After clamping is completed, the loading and unloading dust collection plate 7 is pulled out along the guide frame 8 to prepare for the placement plate 2 to flip.After the moving frame 3 drives the laser marking device 4 to complete the laser marking of the label, it returns to the front end of the placement plate 2 on the marking table 1, and then continues to move away from the placement plate 2. At this time, the electric locking push rod 510 drives the locking pin 511 away from the locking groove 512 of the placement plate 2. The moving frame 3 continues to move until the laser marking device 4 and the high and low undulating wheel 25 are completely moved out of the top of the placement plate 2. At this time, the abutting displacement block 504 drives the slide rod 503 to slide backward in the first slide groove 506. The first spring 507 is compressed. While the displacement block 504 moves backward, it slides through the guide post 505 at its bottom and the groove on the periphery of the cylindrical cam 502, thereby driving the cylindrical cam 502 and the rotating rod 501 to rotate 180°, so that the placement plate 2 As the rotating frame 3 moves backward, gear 616 meshes with rack 617 on the marking stage 1 and rotates. At this time, the rotating gear 616 meshes with ratchet 619 through the inner groove of ratchet ring 615, thereby driving the fixed disk 618 and the first docking rod 601 to rotate. The rotating first docking rod 601 drives the second docking rod 602 to rotate synchronously through the meshing of two bevel gears 613. The rotation of the first docking rod 601 drives the disk 620 to rotate. The inclined block 622 of the elastic sliding fit positioning frame 621 on the moving frame 3 engages with the groove on the periphery of the disk 620. When the first docking rod 601 and the second docking rod 602 rotate, they respectively drive the first torsion spring 605 and the second torsion spring 606 at their ends to compress. The inclined block 622 and the disk 620... The groove on the periphery of the disc 620 limits its movement. When the first docking rod 601 and the second docking rod 602 rotate, they drive the first docking block 603 and the second docking block 604 away from the top of the placement plate 2 through the first threaded section 607 and the second threaded section 609, respectively, to reset. When laser marking is required for the next label, the servo motor 26 drives the moving frame 3 to move upward toward the placement plate 2 through the first screw 27. At this time, when the gear 616 meshes with the rack 617 on the marking stage 1, the gear 616 does not mesh with the ratchet tooth 619 through the inner groove of the ratchet ring 615, and the first docking rod 601 and the second docking rod 602 do not rotate. When it moves to the position of the protrusion 623, the moving frame 3 stops for a period of time. At this time, the positioning frame 62 1. The bottom abuts against the protrusion 623 and lifts it up, thereby moving the inclined block 622 away from the groove around the disc 620. At this time, the first docking rod 601 and the second docking rod 602 rotate through the elastic force released by the first torsion spring 605 and the second torsion spring 606, thereby driving the first docking block 603 and the second docking block 604 to move to the edge of the sign on the placement plate 2 respectively. The first docking block 603 abuts against one side of the guide block 23 through one end of the electric telescopic rod 29, driving the guide block 23 to compress the second spring 30 and move the laser marking device 4 to the marking position of the sign. For signs of different widths, it is not necessary to adjust the position of the laser marking device 4 multiple times. It can be moved to the marking position of different sizes of signs according to the docking assembly 6.Push the unloaded loading / unloading dust collection plate 7 under the placement plate 2, start the dust collector 16, and the dust collector 16 draws the dust collection box 12 to a negative pressure state through the pipeline. At the same time, its air outlet supplies air to the air blowing strip 14 through the pipeline. Several nozzles 15 on the air blowing strip 14 blow air onto the surface of the marked nameplate and into the marked groove, blowing out residual dust, debris, slag particles and other impurities. The impurities are sucked into the dust collection box 12 through the dust suction port 13 on the bottom wall of the placement groove 9 for collection and cleaning. After cleaning, release the second cylinder 18 and the third cylinder 20, remove the marked nameplate from the placement plate 2, and then place the new unmarked nameplate into the placement groove 9 of the loading / unloading dust collection plate 7. Repeat the above process to achieve continuous cyclic laser marking operation of the nameplate.
