Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] like Figure 1-4 As shown, this utility model provides a novel marking machine, including a frame 1. A controller 2, a fixing frame 3, and a fixing plate 4 are bolted to the top of the frame 1. A first cylinder 10 is bolted to the lower surface of the fixing frame 3. A base 11 is bolted to the bottom of the first cylinder 10. A camera 12 and a laser generator 13 are mounted on the lower surface of the base 11. A smoke extraction pipe 14 is fixedly connected inside the base 11. A first flexible hose 15 is provided at the end of the smoke extraction pipe 14. An exhaust pipe 16 is provided at the end of the first flexible hose 15 away from the smoke extraction pipe 14. An efficient filter 17, an activated carbon filter layer 18, and a fan 23 are provided inside the exhaust pipe 16. The upper part of the fixing plate 4... The surface is equipped with an air pump 24 and a second cylinder 26. A second hose 25 is provided on the top of the air pump 24. A connecting pipe 27 is provided at the end of the second hose 25 away from the air pump 24. A fan cover 28 is fixedly connected to the end of the connecting pipe 27 away from the second hose 25. The top of the second cylinder 26 is connected to the connecting pipe 27. The controller 2 is used to coordinate the operation of each system. The fixing frame 3 and the fixing plate 4 are used to fix the marking component and the dust removal component, respectively. The first cylinder 10 drives the base 11 to move vertically and adjusts the distance between the laser generator 13 and the workpiece. The camera 12 collects the workpiece image in real time and feeds it back to the controller 2 to achieve precise positioning. The laser generator 13 etches the surface of the workpiece with high-energy laser.

[0023] Specifically, a motor 5 is bolted to the outer surface of the frame 1, and an active roller 6 is installed at the output end of the motor 5. A driven roller 7 and a support roller group 9 are rotatably connected inside the frame 1 through bearings. A conveyor belt 8 is installed on the outer surface of the active roller 6 and the driven roller 7. The motor 5 drives the active roller 6 to rotate, which drives the conveyor belt 8 to run continuously, thereby realizing the automatic conveying of the workpiece.

[0024] Specifically, the end of the drive roller 6 furthest from the motor 5 is rotatably connected inside the frame 1. The idler roller group 9 is evenly arranged between the drive roller 6 and the driven roller 7. The even distribution of the idler roller group 9 avoids vibration of the conveyor belt 8 due to gravity, while reducing running resistance and extending the service life of the equipment.

[0025] Specifically, a third cylinder 29 is bolted to the inner surface of the frame 1, and a centering push plate 30 is provided at the output end of the third cylinder 29. The third cylinder 29 and the centering push plate 30 are symmetrically arranged inside the fixed frame 3. The third cylinder 29 drives the centering push plate 30 to move symmetrically, pushing the workpiece on the conveyor belt 8 to the middle position, ensuring the accuracy and consistency of laser marking.

[0026] Specifically, both the high-efficiency filter 17 and the activated carbon filter layer 18 are provided with a connecting plate 19 at the top. A handle 20 is fixedly connected to the upper surface of the connecting plate 19 by welding, and a locking block 21 is fixedly connected to the lower surface of the connecting plate 19. A slot 22 is opened on the upper surface of the exhaust pipe 16. The connecting plate 19 is quickly locked to the slot 22 of the exhaust pipe 16 by the locking block 21. The handle 20 is convenient for operators to lift and disassemble, simplifying the replacement process of the high-efficiency filter 17 and the activated carbon filter layer 18 and improving maintenance efficiency.

[0027] Specifically, the outer surface of the card block 21 is adapted to the inner surface of the card slot 22. The activated carbon filter layer 18 is set outside the high-efficiency filter 17, and the fan 23 is set outside the activated carbon filter layer 18. The activated carbon filter layer 18 is a box with through holes filled with activated carbon. The high-efficiency filter 17 acts as a primary filter layer to intercept large particles, and the activated carbon filter layer 18 acts as a secondary filter to adsorb volatile organic compounds and odors. The dual purification ensures that the emitted air meets environmental protection standards.

[0028] The working principle and beneficial effects of the above embodiments.

[0029] During operation, the PCB multilayer board is placed at the edge of the feeding end of the conveyor belt 8. Two sets of third cylinders 29 drive the centering push plate 30 to push the item to the middle of the conveyor belt 8 for centering, ensuring the accuracy of subsequent marking. At this time, the PCB multilayer board is held by the two centering push plates 30. The air pump 24 is started, so that the airflow passes through the second hose 25 and the connecting pipe 27 and is blown out from the fan shroud 28. The high-speed airflow blows towards the surface of the PCB multilayer board, removing the dust on its surface. Then, the third cylinder 29 is shortened to release the PCB multilayer board, while the second cylinder 26 is extended. The connecting pipe 27 and the hood 28 are raised, and the motor 5 drives the active roller 6, which in turn drives the driven roller 7 and the idler roller group 9 to work together. The PCB multilayer board is transported to the working area by the conveyor belt 8. Then, the first cylinder 10 drives the base 11 to move vertically downward to a suitable height. The camera 12 installed on the base 11 performs real-time image acquisition on the PCB multilayer board and feeds back the position information to the controller 2. The controller 2 dynamically adjusts the coordinate parameters of the laser generator 13 according to the feedback data to ensure that the laser beam is accurately focused on the preset marking position. After the laser generator 13 is started, it passes through a high... A laser beam can mark the surface of a multilayer PCB board. Activating fan 23 causes suction in the fume extraction pipe 14, drawing in smoke and debris generated during marking. The smoke and debris are then drawn into the exhaust pipe 16 via the first flexible hose 15. The exhaust pipe 16 contains a high-efficiency filter 17 and an activated carbon filter layer 18 arranged sequentially from the inside out. The high-efficiency filter 17 uses multi-layer composite filter material to intercept particulate matter, while the activated carbon filter layer 18 removes harmful gases and odors through physical adsorption. This ensures continuous smoke intake and double purification before the exhaust of clean air, effectively preventing environmental pollution and achieving high efficiency. Both the filter 17 and the activated carbon filter layer 18 are engaged in the slot 22 on the exhaust pipe 16 by the locking block 21 at the bottom of the connecting plate 19, making the high-efficiency filter 17 and the activated carbon filter layer 18 detachable. The operator can easily pull the handle 20 to disengage the locking block 21 from the slot 22 and quickly replace the filter material to ensure filtration efficiency. In summary, this marking machine, through precise positioning by mechanical transmission, efficient operation by laser etching, intelligent filtration and environmental protection, and automated control, not only significantly improves marking accuracy and efficiency, but also greatly reduces manual intervention and environmental pollution.
