[0002] Printed circuit boards (PCBs) are important electronic components. They serve as the support for electronic components and the carrier for the electrical interconnection of these components. Their processing quality directly affects the performance and reliability of electronic products. Currently, common PCB depaneling methods include mechanical cutting, stamping depaneling, and laser depaneling.

[0003] However, most existing laser PCB separation equipment adopts a single fixed mode, which makes it difficult to quickly adapt to PCBs of different sizes. Uneven clamping force can easily cause local deformation of the PCB. During the cutting process, there is a lack of effective cleaning and dust removal measures. The debris and dust generated during cutting can easily adhere to the surface of the PCB, which not only affects the cutting quality but may also lead to electrical faults such as short circuits, reducing product yield. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PCB multi-channel laser depaneling and cutting device. It solves the problems that most existing laser depaneling equipment adopts a single fixed mode, which makes it difficult to quickly adapt to PCBs of different sizes, and the uneven clamping force can easily cause local deformation of the PCB. In addition, during the cutting process, there is a lack of effective cleaning and dust removal measures, and the debris and dust generated during cutting can easily adhere to the surface of the PCB, which not only affects the cutting quality, but may also lead to electrical faults such as short circuits and reduce product yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PCB multi-channel laser depaneling and cutting device includes a processing table. Slides are symmetrically fixedly mounted on the upper end of the processing table. A cross groove is formed at the center of the upper end of the processing table. Fixing strips are fixedly mounted on the two slides. Hydraulic cylinders are fixedly mounted on the sidewalls of the fixing strips. An electric telescopic rod is mounted on the output end of each hydraulic cylinder. Slide rods are slidably mounted inside the two slides. A U-shaped frame is fixedly mounted on the lower end of each slide rod. Threaded blocks are symmetrically fixedly mounted on the U-shaped frame. Threaded cylinders are threaded onto both ends of each of the two threaded blocks. A laser cutting head is slidably mounted inside the threaded cylinder. First circular grooves are symmetrically formed on the laser cutting head.

[0007] A purging mechanism is slidably installed inside the U-shaped frame;

[0008] The purging mechanism includes a bracket, which is slidably installed in a U-shaped frame, and a second circular groove is symmetrically opened in the inner wall of the bracket.

[0009] Preferably, a fan is fixedly installed inside the bracket, an air duct is fixedly installed on the fan, and an air outlet strip is installed at the end of the air duct away from the fan.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This equipment can provide uniform and stable clamping force, ensuring that the PCB board will not be displaced due to vibration, laser energy impact and other factors during the multi-channel laser depaneling process, thus ensuring high precision and consistency of cutting, effectively reducing the scrap rate caused by loose PCB board, and improving product quality and production yield.

[0016] Second, the fan can be turned on during the cutting process. The fan will blow air out through the air duct and air outlet strip. As the slide bar moves, the air outlet strip will blow off the dust and impurities on the PCB board, so that the equipment can keep the PCB board in a clean state during processing, effectively avoiding interference from impurities and dust, and enhancing the PCB board cutting effect.

[0024] This application provides a multi-channel laser PCB depaneling and cutting device, effectively solving the problems of existing laser depaneling equipment, which mostly adopts a single fixed mode, making it difficult to quickly adapt to PCBs of different sizes, and uneven clamping force that easily causes local deformation of the PCB. Furthermore, the lack of effective cleaning and dust removal measures during the cutting process allows debris and dust generated during cutting to easily adhere to the PCB surface, affecting cutting quality and potentially causing electrical faults such as short circuits, thus reducing product yield. This device provides uniform and stable clamping force, ensuring that the PCB does not shift due to vibration, laser energy impact, or other factors during multi-channel laser depaneling and cutting, guaranteeing high precision and consistency in cutting, effectively reducing scrap rates caused by PCB loosening, and improving product quality and production yield. During the cutting process, a fan can be activated, blowing air through the air duct and exhaust strip. As the slide bar moves, the exhaust strip first blows off dust and impurities from the PCB, keeping the PCB clean during processing, effectively avoiding interference from impurities and dust, and enhancing the PCB cutting effect.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problems of existing laser PCB depaneling equipment, which mostly adopts a single fixed mode, making it difficult to quickly adapt to PCBs of different sizes, and uneven clamping force easily causing local deformation of the PCB; during the cutting process, there is a lack of effective cleaning and dust removal measures, and the debris and dust generated during cutting easily adhere to the surface of the PCB, which not only affects the cutting quality, but may also lead to electrical faults such as short circuits, reducing product yield. The overall idea is as follows: a multi-channel laser PCB depaneling and cutting device, including a processing table 11, with sliding surfaces symmetrically fixedly installed on the upper end of the processing table 11. The frame 12 and the processing table 11 have a cross groove 13 at the center of the upper end. The two slides 12 are fixedly installed with fixing bars 14. The side walls of the fixing bars 14 are fixedly installed with hydraulic cylinders 15. The output end of the hydraulic cylinders 15 is installed with an electric telescopic rod 16. The two slides 12 are slidably installed with slide rods 21. The lower end of the slide rods 21 is fixedly installed with U-shaped frames 22. Threaded blocks 23 are symmetrically fixedly installed on the U-shaped frames 22. Threaded cylinders 24 are threaded at both ends of the two threaded blocks 23. Laser cutting heads 25 are slidably installed inside the threaded cylinders 24. The laser cutting heads 25 are symmetrically provided with first circular grooves 26.

[0027] A purging mechanism is slidably installed inside the U-shaped frame 22;

[0028] The purging mechanism includes a bracket 27, which is slidably installed in a U-shaped frame 22. The inner wall of the bracket 27 is symmetrically provided with second circular grooves 28. When it is necessary to disassemble the laser cutting head 25 and the bracket 27, two sets of threaded cylinders 24 can be rotated on the threaded block 23. Under the rotation of the two sets of threaded cylinders 24, they will slide out from the two sets of first circular grooves 26 and second circular grooves 28 respectively, thus completing the disassembly and separation of the laser cutting head 25 and the bracket 27. This makes it convenient to load and unload the laser cutting head 25 and the bracket 27 during use.

[0029] A fan 29 is fixedly installed inside the mounting bracket 27, and an air duct 31 is fixedly installed on the fan 29. An air outlet strip 32 is installed at the end of the air duct 31 away from the fan 29. After the PCB board is fixed, the hydraulic cylinder 15 can be activated, and the electric telescopic rod 16 will extend and retract. Then, the electric telescopic rod 16 will push the slide rod 21 to slide on the two slides 12. At this time, the laser cutting head 25 will perform laser cutting on the PCB board. During the cutting process, the fan 29 can also be activated. Under the action of the fan 29, air will be blown out through the air duct 31 and the air outlet strip 32. As the slide rod 21 moves, the air outlet strip 32 will first blow off the dust and impurities on the PCB board, so that the equipment can keep the PCB board in a clean state during processing, effectively avoiding the interference of impurities and dust, and enhancing the cutting effect of the PCB board.

[0030] A cross block 33 is symmetrically slidably installed inside the cross groove 13. A first screw 34 is fixedly installed at the lower end of each cross block 33, and a first threaded ring 35 is threaded onto each of the two first screws 34. A placement seat 36 is fixedly installed at the upper end of each cross block 33, and a second screw 37 is fixedly installed on each of the two placement seats 36. A second threaded ring 38 is threaded onto each of the two second screws 37. A silicone strip 39 is slidably installed inside each of the two placement seats 36, and a spring 41 is symmetrically fixedly installed at the lower end of each of the two silicone strips 39. The ends of the two springs 41 furthest from the two silicone strips 39 are respectively fixedly connected to the two placement seats 36. In use, the two placement seats 36 can be moved towards the center within the cross groove 13. At this time, the two placement seats 36 will drive the two cross blocks 33 to slide towards the center within the cross groove 13. When the distance between the two placement seats 36 is equal to that of the PCB board, the two first threaded rings 35 are rotated on the two first screws 34 to complete the fixation. At this time, the PCB board can be placed on the two placement seats 36. Then, the two silicone strips 39 can be rotated on the two second screws 37 respectively. Under the rotation of the two second threaded rings 38, the silicone strips 39 will be squeezed downward, causing them to slide downward. At this time, the two sets of springs 41 will be compressed accordingly. At this time, the two silicone strips 39 will fix the two ends of the PCB board. This structural design can provide uniform and stable clamping force, ensuring that the PCB board will not be displaced due to vibration, laser energy impact, or other factors during multi-channel laser depaneling. This ensures high precision and consistency in cutting, effectively reduces the scrap rate caused by PCB board loosening, and improves product quality and production yield.

[0031] To address the problems existing in the prior art, this utility model provides a PCB multi-channel laser depaneling and cutting device. This device can provide uniform and stable clamping force, ensuring that the PCB board will not be displaced due to vibration, laser energy impact, or other factors during the multi-channel laser depaneling and cutting process. This guarantees high precision and consistency in cutting, effectively reducing the scrap rate caused by PCB board loosening, and improving product quality and production yield. During the cutting process, the fan 29 can be activated. Under the action of the fan 29, air is blown out through the air duct 31 and the air outlet 32. As the slide bar 21 moves, the air outlet 32 ​​first blows off the dust and impurities on the PCB board, so that the device can keep the PCB board in a clean state during processing, effectively avoiding interference from impurities and dust, and enhancing the PCB board cutting effect.

[0032] in:

[0033] Processing table 11: As the basic load-bearing component of the entire device, the upper end of the table is symmetrically fixed with a slide 12, which provides a guide rail for the sliding of the slide bar 21 and ensures the stability of the movement of the cutting component; the cross groove 13 opened at the center, together with the cross block 33, realizes the flexible adjustment of the position of the placement seat 36 to adapt to the fixing requirements of PCB boards of different sizes. This design enables the device to quickly adapt to diverse production tasks and improves the versatility and processing efficiency of the equipment.

[0034] Slide 12: Installed on the upper end of the processing table 11, it not only provides stable sliding support for slide rod 21, but also, through its coordinated work with fixed bar 14, hydraulic cylinder 15 and electric telescopic rod 16, achieves precise control of the position of slide rod 21. During the cutting process, slide rod 21 can move stably along the preset path, ensuring that laser cutting head 25 accurately cuts PCB board, effectively improving the cutting accuracy and consistency.

[0035] Fixed bar 14: Fixed on the slide 12, its main function is to provide a stable mounting base for the hydraulic cylinder 15. Through this connection method, the extension and retraction of the hydraulic cylinder 15 can be reliably transmitted to the electric telescopic rod 16, thereby pushing the slide rod 21 to slide on the slide 12, ensuring the motion accuracy and stability of the laser cutting head 25, and providing a strong guarantee for achieving high-quality PCB board cutting.

[0036] Hydraulic cylinder 15 and electric telescopic rod 16: Hydraulic cylinder 15 serves as a power source, driving the electric telescopic rod 16 to extend and retract by outputting a stable thrust or pull force. The electric telescopic rod 16 precisely transmits the power of hydraulic cylinder 15 to slide rod 21, enabling smooth sliding of slide rod 21 on slide frame 12. This power transmission system provides precise displacement control, meeting the stringent requirements of different cutting processes for the speed and position accuracy of the cutting head, ensuring the stability and reliability of the laser cutting process.

[0037] Slide bar 21: Slidingly installed inside the two slides 12, with a U-shaped frame 22 fixed at its lower end supporting the laser cutting head 25 and the blowing mechanism. Driven by the hydraulic cylinder 15 and the electric telescopic rod 16, the slide bar 21 can move precisely on the slide 12, thereby driving the laser cutting head 25 and the blowing mechanism to cut and clean the PCB board according to a predetermined trajectory, ensuring the accuracy and efficiency of the cutting process;

[0038] U-shaped frame 22: provides mounting support for laser cutting head 25 and purging mechanism. Its symmetrically installed threaded blocks 23 cooperate with threaded cylinder 24 to realize convenient disassembly and installation of laser cutting head 25 and insert 27. This modular design facilitates equipment maintenance, upgrades and replacement of different functional modules, and improves the equipment's flexibility and maintenance efficiency.

[0039] Laser cutting head 25: As the core cutting component of the device, the laser cutting head 25 emits a high-energy laser beam during the cutting process to precisely cut the PCB board. Its installation method facilitates quick and convenient operation when maintenance or replacement of cutting heads with different power or models is required, so as to adapt to different PCB board cutting needs and ensure cutting quality and efficiency.

[0040] Blowing mechanism (insert bracket 27, fan 29, air duct 31, air outlet strip 32): The internally fixed fan 29 generates a strong airflow, which is transmitted to the air outlet strip 32 through the air duct 31 and blown out. During the laser cutting process, the air outlet strip 32 can promptly blow off the dust and impurities on the surface of the PCB board, effectively avoiding the interference of impurities on the cutting quality, maintaining the cleanliness of the PCB board during processing, improving the cutting effect and product quality. At the same time, the detachable connection between the insert bracket 27 and the U-shaped bracket 22 facilitates the maintenance and cleaning of the blowing mechanism, ensuring its continuous and stable operation.

[0041] Cross block 33: The first screw 34 fixed at the lower end cooperates with the first threaded ring 35 to fix the cross block 33 after the position is adjusted;

[0042] First screw 34 and first threaded ring 35: After the two placement seats 36 are adjusted to the appropriate distance, rotate the first threaded ring 35 to move and lock it on the first screw 34, thereby fixing the cross block 33 in a specific position in the cross groove 13. This threaded connection method provides a reliable fixing effect, ensuring that the placement seat 36 will not be displaced during the PCB board fixing and cutting process, thus ensuring the cutting accuracy.

[0043] Placement seat 36: Used to place PCB board. The second screw 37 set above it, the silicone strip 39 slidably installed inside, and the spring 41 connected below together constitute a flexible fixing system for PCB board. This system can ensure that the PCB board is firmly fixed during the cutting process and avoid damage to the PCB board due to excessive pressure.

[0044] The second screw 37, the second threaded ring 38, the silicone strip 39, and the spring 41: The elastic force provided by the spring 41 enables the silicone strip 39 to press the two ends of the PCB board with uniform and stable pressure. This flexible fixing method ensures that the PCB board will not be displaced due to vibration or laser energy impact during the cutting process, and avoids scratching or damage to the PCB board surface caused by rigid clamping. It effectively ensures high precision and consistency of cutting, and improves product quality and production yield.

[0045] Working principle:

[0046] First, during use, move the two placement seats 36 towards the center in the cross groove 13. At this time, the two placement seats 36 will drive the two cross blocks 33 to slide towards the center inside the cross groove 13. When the distance between the two placement seats 36 is equal to that of the PCB board, rotate the two first threaded rings 35 on the two first screws 34 to complete the fixation. At this time, the PCB board can be placed on the two placement seats 36. Then, rotate the two silicone strips 39 on the two second screws 37 respectively. Under the rotation of the two second threaded rings 38, the silicone strips 39 will be squeezed downward, causing them to slide downward. At this time, the two sets of springs 41 will be compressed accordingly. At this time, the two silicone strips 39 will fix the two ends of the PCB board. This structural design can provide uniform and stable clamping force, ensuring that the PCB board will not be displaced due to vibration, laser energy impact and other factors during the multi-channel laser board cutting process, ensuring high precision and consistency of cutting, effectively reducing the scrap rate caused by PCB board loosening, and improving product quality and production yield.

[0047] In the second step, after the PCB board is fixed, the hydraulic cylinder 15 can be activated, and the electric telescopic rod 16 will extend and retract. Then, the electric telescopic rod 16 will push the slide rod 21 to slide on the two slides 12. At this time, the laser cutting head 25 will perform laser cutting on the PCB board. During the cutting process, the fan 29 can also be activated. Under the action of the fan 29, the air will be blown out through the air duct 31 and the air outlet 32. As the slide rod 21 moves, the air outlet 32 ​​will first blow off the dust and impurities on the PCB board, so that the equipment can keep the PCB board in a clean state during processing, effectively avoiding the interference of impurities and dust, and enhancing the cutting effect of the PCB board.

[0048] Third, when it is necessary to disassemble the laser cutting head 25 and the insert 27, two sets of threaded cylinders 24 can be rotated on the threaded block 23. Under the rotation of the two sets of threaded cylinders 24, they will slide out from the two sets of first circular grooves 26 and second circular grooves 28 respectively, thus completing the disassembly and separation of the laser cutting head 25 and the insert 27, making it convenient to load and unload the laser cutting head 25 and the insert 27 when using the equipment.

[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
