[0037] Please refer to Figures 1-6As shown, an automatic offline milling and separating machine includes a frame 10 and a cutting mechanism 20 disposed on the frame 10. The upper end of the frame 10 is provided with a working platform 11, and the cutting mechanism 20 is disposed below the working platform 11. The working platform 11 is provided with a feeding mechanism 30, a separating station and a discharging mechanism 60 in sequence along the moving direction of the PCB board. The separating station includes a first station 40 and a second station 50 arranged side by side. Both the first station 40 and the second station 50 are provided with trays for placing PCB boards. A transfer double robot arm 70 and a pressure plate mechanism 80 are provided on the side of the separating station. The pressure plate mechanism 80 includes a pressure plate 80 for fixing the PCB board on the tray and a transfer drive assembly for driving the pressure plate 80 to move between the first station 40 and the second station 50. By employing a dual-link manipulator 70 for material transfer, the loading and unloading structure is simplified, reducing equipment complexity and manufacturing costs. The inclusion of a pressure plate 80 and a transfer drive assembly allows each PCB separation station to share a single pressure plate mechanism 80, further reducing production costs and enhancing automation. During operation, the PCBs to be separated can be placed on a tray or via a fixture. Both the tray and fixture have clearance slots corresponding to the slitting line.

[0038] Specifically, the actuator of the dual-link manipulator 70 is equipped with a first suction plate 71 for moving the PCB board to be divided from the feeding mechanism 30 to the PCB board separating station, and a second suction plate 72 for moving the divided PCB board from the PCB board separating station to the discharging mechanism 60. The lower surfaces of both the first suction plate 71 and the second suction plate 72 are equipped with suction cups. The suction cups on the second suction plate 72 are distributed according to the number of PCB boards to be separated and are independently controlled, so that good PCB boards and defective PCB boards can be picked up and placed separately during material transfer. 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 direction, a Z-axis drive assembly 23 driven by the Y-axis drive assembly 22 to move along the Y-axis direction, and an electric spindle 24 driven by the Z-axis drive assembly 23 to move along the Z-axis direction. The output end of the electric spindle 24 extends upwards. A dust collection hood 25 is fixedly installed on the side of the electric spindle 24. The dust collection hood 25 is equipped with a dust collection pipe 26. During the slitting operation, an external dust collection device removes the dust generated during slitting through the dust collection pipe 26 and the dust collection hood 25. The X-axis drive assembly 21, Y-axis drive assembly 22, and Z-axis drive assembly 23 all adopt technical means with low cost in the field, and will not be described in detail here.

[0039] In this invention, the pressure plate mechanism 80 further includes a plate-moving slide rail 82 parallel to both sides of the first station 40 and the second station 50. The extension direction of the plate-moving slide rail 82 is parallel to the moving direction of the PCB board. Each plate-moving slide rail 82 is provided with a plate-moving slide seat 85, and each plate-moving slide seat 85 is equipped with a pressing drive mechanism 86. A connecting frame 87 is fixedly provided at the upper end of the pressure plate 80, and both ends of the connecting frame 87 are respectively connected to the driving ends of the corresponding pressing drive mechanism 86. The plate-moving drive assembly includes a plate-moving motor 83 and a synchronous belt 84 driven by the plate-moving motor 83. One plate-moving slide seat 85 is fixedly connected to one side of the synchronous belt 84 and is driven by the synchronous belt 84 to slide along the plate-moving slide rail 82. The other plate-moving slide seat 85 is driven by the connecting frame 87 to slide synchronously along the corresponding plate-moving slide rail 82. During operation, the transfer motor 83 moves the connecting frame 87 to the current board-separating station via the synchronous belt 84. Then, the pressing drive mechanism 86 controls the pressure plate 80 to press down. Then, the slitting mechanism 20 performs board separation on the PCB board at the current board-separating station. At the same time, the second suction plate 72 of the transfer double robot arm 70 takes out the PCB board that has been separated at another station, and the first suction plate 71 puts the PCB to be separated back in.

[0040] In this invention, an upwardly extending guide rod 88 is fixedly provided on the connecting frame 87, and a guide sleeve 89 is provided on the sliding plate slide 85. The upper end of the guide rod 88 is slidably connected to the guide sleeve 89. The cooperation between the guide rod 88 and the guide sleeve 89 improves the consistency of the vertical movement of the connecting frame 87. In this invention, the downward driving mechanism 86 is a downward cylinder. It should be understood that in practical applications, the downward driving mechanism 86 can also be other driving mechanisms capable of lifting functions, such as motors, electric cylinders, etc.

[0041] Specifically, a waste discharge port 12 is provided between the PCB separation station and the discharge mechanism 60, and the waste discharge port 12 is connected to a waste discharge chute 13. The discharge mechanism 60 includes a discharge slide rail 62, a discharge slide block 61, and a discharge drive assembly 63. The discharge slide rail 62 extends to the side of the waste discharge port 12, and the extension direction of the discharge slide rail 62 is parallel to the movement direction of the PCB board. The discharge slide block 61 is disposed on the discharge slide rail 62 and is driven by the discharge drive assembly 63 to slide along the discharge slide rail 62. When a defective product is detected, the second suction plate 72 of the transfer double-barrel manipulator 70 first moves to the waste discharge outlet 12 to discharge the defective product from the waste discharge chute 13. Then, the discharge drive assembly 63 blocks the waste discharge outlet 12 via the discharge slide 61, and the second suction plate 72 places the good product onto the tray of the discharge slide 61. Alternatively, the second suction plate 72 can first place the good product onto the tray of the discharge slide 61, then the discharge slide 61 moves away from the waste discharge outlet 12, and then the defective product is discharged through the waste discharge chute 13. In this invention, the discharge drive assembly 63 uses a motor and a lead screw to drive the discharge slide 61 to slide along the discharge rail 62. The feeding mechanism 30 uses a motor-driven belt to transport the PCB board to be cut.

[0042] In this utility model, the frame 10 is also equipped with a control unit (not shown), and the cutting mechanism 20, feeding mechanism 30, discharging mechanism 60, material transfer double robot arm 70 and pressure plate mechanism 80 are all controlled by the controller.

[0043] In summary, this utility model, by employing a down-milling method, avoids the need for flipping plates when components are too tall, thereby improving production efficiency and reducing operating costs. The slitting mechanism, installed below the work platform, also reduces the overall size of the equipment. The use of a dual-link manipulator for material transfer simplifies the loading and unloading structure, reducing equipment complexity and manufacturing costs. Furthermore, by incorporating a pressure plate and a plate-shifting drive assembly, a single pressure plate mechanism can be shared across the slitting stations, further reducing production costs and enhancing the automation level of the equipment.

[0044] 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.
