[0047] As a preferred embodiment, to save space, the machine platform 1 is provided with an internal active space, within which the cutting mechanism 2 is mounted. A cutting clearance 11 communicating with the active space is provided on the tabletop of the machine platform 1. The processing end of the cutting mechanism 2 is configured to pass through the cutting clearance 11 to cut the PCBs 100 on the feed mechanism 4. There are at least two feed mechanisms 4, distributed from left to right on the feed frame 3. Each feed mechanism 4 has a corresponding cutting clearance 11 directly below it, forming a dual workstation.

[0048] In this embodiment, the cutting mechanism 2 includes a cutting spindle 21 for driving the milling cutter 200 to rotate and a three-axis cutting movement mechanism 22 for driving the cutting spindle 21 to move in the XYZ directions. The fixed end of the three-axis cutting movement mechanism 22 is installed on the machine table 1, and the action output end is connected to the cutting spindle 21, thereby driving the cutting spindle 21 to move in the XYZ directions, thereby performing the cutting action of the PCB circuit board 100.

The camera lifting mechanism 24 is used to drive the industrial camera 23 to move up and down relative to the action output end of the cutting three-axis moving mechanism 22, so that when the cutting spindle 21 changes the tool, the industrial camera 23 can be driven down to make the height of the industrial camera 23 and the cutting spindle 21 staggered, thereby avoiding the industrial camera 23 affecting the tool change of the cutting spindle 21.

[0050] When the tool needs to be changed, the action output end of the cutting three-axis moving mechanism 22 drives the industrial camera 23 and the cutting spindle 21 to move to the tool holder 6 position. The industrial camera 23 is used to detect whether there is a milling cutter 200 on the tool holder 7. After detecting that there are milling cutters 200 on those tool holders 7, the original milling cutter 200 on the cutting spindle 21 is first inserted into the clamping mouth of the tool holder 7 without the milling cutter 200, and then the original milling cutter 200 is clamped by the clamping mouth of the tool holder 7. Then the cutting spindle 21 is moved to the position of the tool holder 7 with the milling cutter 200 to clamp the new milling cutter 200, thereby completing the tool change.

[0052] In this embodiment, the unloading linkage rack 85 is located on one side of the bottom of the material tray 82, and a unloading pad 86 is provided on the other side of the bottom of the material tray 82. The unloading slider is mounted on the bottom of both the unloading linkage rack 85 and the unloading pad 86. Furthermore, the material tray 82 is provided with an unloading avoidance groove 821 for avoiding the conveying support ring 4041.

By inputting control parameters into the control device 9, the worker can allow the control device 9 to control each part to automatically perform corresponding actions, thereby realizing online and data-based control of the panel splitter.

[0054] When the board separator is working, the PCB circuit board 100 is placed between the first conveying unit 41 and the second conveying unit 42 of the feeding mechanism 4 by manual placement or conveying with a conveyor belt. At this time, the bottom of the PCB circuit board 100 is supported by the conveying support ring 4041, and the left and right sides of the PCB circuit board 100 are in rolling contact with the conveying surface of the conveying wheel 404, so that the PCB circuit board 100 moves toward the in-place stopper 403; when the PCB circuit board 100 is blocked by the in-place stopper 403 and detected by the in-place monitoring switch on the in-place stopper 403, the conveying wheel 404 stops rotating, and then the side pressing member 412 is actuated to press the PCB circuit board 100, so that the PCB circuit board 100 cannot move left and right, and the top pressure rod 433 is pressed on the top of the PCB circuit board 100, so that the PCB circuit board 100 cannot move up and down; then the cutting spindle 21 cuts the PCB circuit board 100;

[0055] After the PCB circuit board 100 is cut, the feeding mechanism 4 releases the PCB circuit board 100, and then the unloading motor unit 83 drives the unloading drive gear 84 to rotate, so that the unloading linkage rack 85 and the material tray 82 are moved to the bottom of the feeding mechanism 4; then the conveying wheel 404 and the PCB circuit board 100 are controlled to descend synchronously, wherein the conveying support ring 4041 extends into the unloading avoidance groove 821, so that the cut PCB circuit board 100 can be placed on the material tray 82, and then the left and right drive units 407 are used to control the conveying wheel 404. The conveying support ring 4041 of the first conveying unit 4 moves away from the bottom of the cut PCB circuit board 100, and then the conveying wheels 404 of the first conveying unit 41 and the second conveying unit 42 are lifted, completing the action of placing the cut PCB circuit board 100 into the material tray 82; after the feeding mechanism 4 places the cut PCB circuit board 100 into the material tray 82, the unloading motor unit 83 is linked to the material tray 82 to reset, thereby moving the PCB circuit board 100 out from under the feeding mechanism 4, completing the unloading action of the cut PCB circuit board 100.

[0056] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the scope of protection of the present invention.
