[0033] As Figures 1-5As shown, an offline downmilling and PCB splitting machine includes a frame 10 and a slitting mechanism 20 mounted on the frame 10. A work platform 11 is located at the upper end of the frame 10, and the slitting mechanism 20 is positioned below the work platform 11. The slitting mechanism 20 includes an X-axis drive assembly 21, a Y-axis drive assembly 22 driven by the X-axis drive assembly 21 to move along the X-axis, a Z-axis drive assembly 23 driven by the Y-axis drive assembly 22 to move along the Y-axis, and an electric spindle 24 driven by the Z-axis drive assembly 23 to move along the Z-axis. The work platform 11 has a first window for the slitting mechanism 20 to be exposed, and a tray 30 for placing PCB boards is provided at the first window. By using downmilling, the need for flipping components due to their height is avoided, improving production efficiency and reducing operating costs. The slitting mechanism 20's placement below the work platform 11 also reduces the overall size of the equipment and improves safety during use. Furthermore, the tray 30 is fixed, requiring only the electric spindle 24 to be moved for PCB splitting operations, resulting in a simpler equipment structure and easier system debugging.
[0034] Specifically, the work platform 11 has a second window next to the first window, and a tool holder 40 is embedded in the second window. The tool holder 40 is equipped with a plurality of downward-extending milling cutters 41. In this invention, the milling cutters 41 on the tool holder 40 are arranged at linear intervals along the X-axis. Using down-milling makes tool changing more convenient and is more conducive to automatic tool changing by the electric spindle 24.
[0035] In this invention, the working platform 11 is provided with a protective cover 50, which has an opening for placing and removing PCB boards. A cover 51 is provided at the opening. The height of the protective cover 50 is greater than the height of the components on the PCB board. The rear side of the cover 51 is hinged to the rear side of the opening, and the front side of the upper surface of the protective cover 50 is a slope 52 that slopes downwards from back to front. By providing the protective cover 50, better protection for workers can be achieved. The slope 52 on the front side of the upper surface of the protective cover 50 makes it easier for workers to place and remove PCB boards. A protective light grille 53 is provided along the edge of the opening. Control buttons 54 are provided on both sides of the opening of the protective cover 50. This dual-button structure requires both control buttons to be pressed during operation to perform milling work, thus better preventing injury due to misoperation.
[0036] Specifically, the protective cover 50 is equipped with a controller 60, and the X-axis drive assembly 21, Y-axis drive assembly 22, Z-axis drive assembly 23, electric spindle 24, protective light grating 53, and control button 54 are all controlled by the controller 60. In this utility model, the X-axis drive assembly 21, Y-axis drive assembly 22, and Z-axis drive assembly 23 are all conventional drive structures in the art, and will not be described in detail here.
[0037] In this utility model, a dust collection hood 25 is fixedly provided on the side of the electric spindle 24, and a dust collection pipe 26 is provided on the dust collection hood 25, so that dust and debris generated during milling can be removed by connecting a dust collection device through the dust collection pipe 26 during the plate separation operation.
[0038] Specifically, the edge of the first window is provided with several fixing holes 12, and the tray 30 is provided with through holes 31 corresponding to the fixing holes 12. The through holes 31 are oblong holes. By using oblong holes, the installation position of the tray 30 can be better adjusted, thereby improving the separation accuracy. In this utility model, two first windows are arranged side by side, and each of the two first windows is provided with a corresponding tray 30, which can improve work efficiency. In this utility model, the PCB board can be directly fixed to the tray 30, or it can be placed on the tray 30 through a positioning fixture plate. Correspondingly, both the tray 30 and the positioning fixture plate are provided with clearance holes or clearance grooves (not shown) for the milling cutter 41 to pass through. In actual operation, the tray 30 or the positioning fixture plate is also covered with a pressure cover (not shown) to prevent the PCB board from moving during separation.
[0039] In this utility model, the bottom end of the frame 10 is provided with casters 13 and height-adjustable feet. When the equipment needs to be moved, the support feet 14 are first retracted, and after the equipment is moved into place, the support feet 14 are extended to support the ground, thereby facilitating the movement of the equipment.
[0040] In summary, this utility model avoids the need for flipping plates when components are too high by using a down-milling method, thereby improving production efficiency and reducing operating costs. The slitting mechanism is also installed below the work platform, which reduces the overall size of the equipment. At the same time, the pallet is fixed, and only the movement of the electric spindle needs to be controlled for the slitting operation, making the equipment structure simpler and the system debugging more convenient.
[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
