The application of PCB splitting machines not only replaces the low efficiency and high error problems of manual splitting, avoiding edge damage and circuit breakage caused by manual board breaking, but also ensures smooth cuts and precise dimensions. However, traditional PCB depaneling machines mostly use a fixed cutting structure or only support manual adjustment in one dimension. The fixed structure cannot adapt to PCBs of different sizes.

[0015] The following is in conjunction with the appendix Figure 1-11 The present invention will be further described below.
[0016] To address the problems existing in the background art, this application proposes the following technical solution: an adjustable PCB board separating machine, including a chassis 1, a fixing frame 2 fixedly connected to the top of the chassis 1, a support plate 3 provided above the chassis 1, a plurality of positioning holes 4 provided on the support plate 3, positioning pins 5 inserted into the positioning holes 4, a first adjustment component provided between the support plate 3 and the chassis 1, an adjustment seat 22 provided outside the fixing frame 2, a laser cutter 24 detachably connected to the outside of the adjustment seat 22, a second adjustment component provided outside the fixing frame 2, a third adjustment component provided outside the second adjustment component, and the third adjustment component connected to the adjustment seat 22. In this embodiment, the chassis 1, as the basic load-bearing structure of the equipment, is made of high-strength metal and can stably support the top mounting bracket 2, support plate 3, and other components, preventing overall displacement due to vibration during equipment operation and ensuring the accuracy of board separation. The first adjustment component between the support plate 3 and the chassis 1 can adjust the position of the support plate 3, making it easy to adjust its relative position with the laser cutter 24 according to the PCB board size, ensuring that the cutting area completely covers the part to be separated. The adjustment seat 22 on the outside of the mounting bracket 2 is used to install the laser cutter 24. Its detachable design facilitates the maintenance, replacement, or upgrading of the laser cutter 24 without the need for complete equipment disassembly, reducing maintenance costs. The second and third adjustment components work together to adjust the position of the adjustment seat 22 and the laser cutter 24 from different dimensions, achieving precise control of the cutting path and solving the problem of fixed cutting position and difficulty in flexible adjustment in traditional board separation machines, thus meeting the board separation requirements of complex PCB boards. In this embodiment, the adjusting base 22 is provided with a snap-fit groove 23 on its exterior. The snap-fit groove 23 has a cylindrical structure. A snap-fit post 25 is fixedly connected to the exterior of the laser cutter 24. Magnets are fixedly connected to the bottom wall of the snap-fit groove 23 and the bottom of the snap-fit post 25, with opposite poles attracting each other. The cylindrical snap-fit groove 23 of the adjusting base 22 and the snap-fit post 25 of the laser cutter 24 are precisely matched, enabling quick positioning and installation of the laser cutter 24. Compared with the traditional bolt fixing method, there is no need for cumbersome disassembly steps, which greatly shortens the installation and replacement time and improves operating efficiency. The opposite pole magnets at the bottom of the snap-fit groove 23 and the snap-fit post 25 cooperate to enhance the stability of the connection between the two through magnetic attraction, preventing the laser cutter 24 from falling off or shifting due to vibration during operation, and ensuring the stability of the cutting process. On the other hand, the magnetic attraction has a certain buffering effect, which can reduce the vibration transmission of the laser cutter 24 during operation and avoid vibration affecting the cutting accuracy. In addition, the cylindrical snap-fit design ensures that the laser cutter 24 remains coaxial during installation, avoiding deviation of the cutting path due to installation angle deviation, and further improving the separation accuracy; the attraction force of the opposite pole magnet is moderate, which can not only ensure a stable connection, but also make it easy for operators to disassemble the laser cutter 24, balancing stability and convenience, and is especially suitable for scenarios that require frequent replacement of different models of laser cutter 24. In this embodiment, the first adjustment component includes a first mounting base 6 fixedly connected to the housing 1 and a first pulley 8 rotatably connected to both sides of the top of the first mounting base 6. A first belt 9 is sleeved on the outside of the first pulley 8. A first motor 7 is fixedly connected inside the housing 1. The output end of the first motor 7 is fixedly connected to one of the first pulleys 8. A first slide rail 11 is fixedly connected to the first mounting base 6. A first sliding seat 10 is slidably connected to the first slide rail 11. The first sliding seat 10 is fixedly connected to the first belt 9 and to the support plate 3. The first mounting base 6 of the first adjustment component provides a stable mounting foundation for components such as pulleys and slide rails, ensuring that the positions of each component are fixed during operation and avoiding adjustment deviations due to loose installation. The first motor 7 serves as a power source, driving one set of first pulleys 8 to rotate, which in turn drives the first belt 9 to drive the first sliding seat 10, which is fixed to the belt, to slide along the first slide rail 11. This belt drive method operates smoothly, with low noise and high transmission accuracy, enabling the support plate 3 to move slowly and uniformly, avoiding PCB board positioning offset due to excessive movement speed or jamming. The first slide rail 11 cooperates with the first sliding seat 10 to provide precise guidance for the movement of the support plate 3, ensuring that the support plate 3 is always adjusted in a straight line and avoiding lateral offset, thereby further ensuring the relative positional accuracy of the PCB board and the laser cutter 24. Compared with the traditional manual adjustment of the support plate 3, this electric adjustment structure not only reduces the labor intensity of the operator, but also achieves precise control of the position of the support plate 3 by controlling the speed and rotation angle of the first motor 7, meeting the positioning requirements of PCB boards of different sizes and improving the automation level and adjustment accuracy of the depaneling machine. In this embodiment, the second adjustment component includes a second pulley 12 rotatably connected to both sides of the outer side of the fixed frame 2 and a second belt 13 sleeved on the outside of the second pulley 12. A second motor 15 is fixedly connected to the outside of the fixed frame 2. The output end of the second motor 15 is fixedly connected to one of the second pulleys 12. A second sliding seat 16 is fixedly connected to the outside of the second belt 13. A second slide rail 14 is fixedly connected to the outside of the fixed frame 2. The second sliding seat 16 is slidably connected to the second slide rail 14. The second adjustment component drives the second pulley 12 and the second belt 13 via the second motor 15, causing the second sliding seat 16 to slide along the second slide rail 14, thereby achieving the first-dimensional position adjustment (such as horizontal adjustment) of the third adjustment component and the laser cutter 24. The transmission structure of the second pulley 12 and the second belt 13 also has the advantages of smooth operation and high precision, ensuring that the second sliding seat 16 moves without significant vibration, thus avoiding affecting the positional stability of the laser cutter 24. In this embodiment, the third adjustment component includes a second mounting base 17 fixedly connected to the outside of the second sliding seat 16 and a threaded rod 19 rotatably connected to the second mounting base 17. A third motor 18 is fixedly connected to the outside of the second mounting base 17, and the output end of the third motor 18 is fixedly connected to the threaded rod 19. A nut is threadedly connected to the outside of the threaded rod 19, and a third sliding seat 20 is fixedly connected to the outside of the nut. An adjustment seat 22 is fixedly connected to the third sliding seat 20, and a third slide rail 21 is fixedly connected to the outside of the second mounting base 17. The third sliding seat 20 is slidably connected to the third slide rail 21. The third adjustment component serves as the second-dimensional adjustment structure of the laser cutter 24 (such as vertical or horizontal adjustment). It drives the threaded rod 19 to rotate via the third motor 18. The threaded engagement between the threaded rod 19 and the nut converts the rotational motion of the motor into the linear motion of the third sliding seat 20. The threaded drive has a self-locking function. When the third motor 18 stops running, the friction between the nut and the threaded rod 19 keeps the third sliding seat 20 stably in its current position, preventing positional deviation due to external forces or vibrations and ensuring the positioning stability of the laser cutter 24. The second mounting base 17 provides stable support for components such as the threaded rod 19 and the third motor 18, ensuring that the threaded rod 19 rotates without radial runout and improving transmission accuracy. The third slide rail 21 cooperates with the third sliding seat 20 to guide the movement of the third sliding seat 20, preventing it from rotating or deviating during movement, further ensuring the movement accuracy of the adjusting base 22 and the laser cutter 24. Through the cooperation of the third adjusting component and the second adjusting component, the laser cutter 24 can be freely adjusted in two dimensions, accurately positioning itself to the cutting position on the PCB board, meeting the separation requirements of complex PCB boards, and greatly improving the flexibility and applicability of the separation machine.
[0017] The usage method of this embodiment is as follows: When using this adjustable PCB board separating machine, first, according to the size and positioning requirements of the PCB board to be separated, insert the positioning pin 5 into the corresponding positioning hole 4 on the support plate 3 to complete the construction of the PCB board positioning structure; then, place the PCB board to be separated stably on the support plate 3, and use the positioning pin 5 to achieve precise fixation of the PCB board, ensuring that the PCB board does not slide or shift. Next, check the connection status between the laser cutter 24 and the adjusting base 22. If the laser cutter 24 needs to be replaced, simply pull the snap pin 25 of the old laser cutter 24 out of the snap slot 23 of the adjusting base 22, and then insert the snap pin 25 of the new laser cutter 24 into the snap slot 23. Use the attraction force of the opposite pole magnets to quickly fix the two together, ensuring that the laser cutter 24 is installed firmly and the coaxiality meets the standard. Then, the power supply of the equipment is turned on, and the first motor 7 is started through the control system. The first motor 7 drives the first pulley 8 to rotate, which drives the first belt 9 to drive the transmission, thereby causing the first sliding seat 10 to slide along the first slide rail 11. The first sliding seat 10 drives the support plate 3 and the PCB board to move, adjusting the area to be cut on the PCB board to the area below the laser cutter 24, thus completing the relative position adjustment of the PCB board and the laser cutter 24 in this dimension. Subsequently, according to the requirements of the PCB board to be cut, the second motor 15 is started. The second motor 15 drives the second pulley 12 to rotate, which drives the second belt 13 to drive the second sliding seat 16 to slide along the second slide rail 14. The second sliding seat 16 drives the third adjustment component and the laser cutter 24 to move, so as to achieve precise positioning of the laser cutter 24 in the first dimension. Then start the third motor 18, which drives the threaded rod 19 to rotate. Through the threaded engagement between the threaded rod 19 and the nut, the third sliding seat 20 slides along the third slide rail 21. The third sliding seat 20 drives the adjusting seat 22 and the laser cutter 24 to move, completing the precise positioning of the laser cutter 24 in the second dimension, until the cutting head of the laser cutter 24 is precisely aligned with the cutting path of the PCB board. After positioning is completed, laser cutting parameters (such as cutting power, cutting speed, etc.) are set through the control system. After confirming that the parameters are correct, the laser cutter 24 is started. The laser cutter 24 cuts the PCB board according to the preset path. During the cutting process, the cutting status can be monitored in real time through the control system. If the cutting position needs to be adjusted, the second motor 15 or the third motor 18 can be started again for fine adjustment. After the PCB board is cut, turn off the laser cutter 24 and start the first motor 7 to drive the support plate 3 to move in the opposite direction, moving the separated PCB board out of the cutting area. Then remove the separated PCB board. If you need to continue separating boards, repeat the above steps of placing the PCB board, adjusting the position, and starting the cutting. If the separation operation is completed, turn off the power of the equipment and clean and maintain the equipment (such as cleaning the cutting residue on the support plate 3 and checking the operating status of each adjustment component).
