Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically to a controller PCB board cutting device. Background Technology

[0002] After a series of manufacturing processes, a PCB board becomes a multilayer board with a complete circuit pattern. At this point, the multilayer board is still a complete board with several PCB units, which need to be cut to obtain individual PCBs. After V-cutting, the entire PCB board can be easily separated into multiple individual PCBs. PCBs cut using this method are generally rectangular. However, due to different controller housing styles, sometimes it is necessary to perform secondary cutting on the blank parts of the controller PCB to modify the PCB's shape to fit the controller housing design. Existing cutting machine guides generally can only perform straight-line cutting, making it inconvenient to adjust the cutting angle. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a controller PCB board cutting device that facilitates the adjustment of the PCB board cutting angle.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a controller PCB board cutting device, including a cutting table and a cutting machine disposed on the cutting table, and further comprising:

[0005] The first guide rail is fixed on the cutting table;

[0006] The first slide block is slidably mounted on the first guide rail;

[0007] The second guide rail is fixed on the first slide block and is perpendicular to the first guide rail.

[0008] The second slide block is slidably mounted on the second guide rail;

[0009] A disc, which is rotatably mounted on a second slide;

[0010] The limiting frame is fixed on the disc and includes two limiting plates. The planes on which the two limiting plates are located are perpendicular, and a clearance notch is provided between the two limiting plates.

[0011] The clamping structure is set on the limit frame and is used to clamp the PCB board.

[0012] Furthermore, the disc has teeth on its circumference, and a swivel is provided on the second slide. A first adjusting rod is rotatably mounted on the swivel, and a gear that meshes with the teeth is fixed at one end of the first adjusting rod.

[0013] Furthermore, a second adjusting rod is threaded onto the rotary seat, which is used to lock the first adjusting rod onto the rotary seat.

[0014] Furthermore, a third adjusting rod is rotatably mounted on the second guide rail, and the third adjusting rod is threadedly engaged with the second slide block.

[0015] Furthermore, the clamping structure includes a fourth adjusting rod, which is threaded onto the limiting frame. A pressure plate is fixed to one end of the fourth adjusting rod near the disc, and a rubber pad is provided on the side of the pressure plate near the disc.

[0016] Furthermore, the limiting frame is L-shaped, with two limiting plates located at the two ends of the L-shape, and the clearance notch located within the included angle of the L-shape.

[0017] Furthermore, there are two first guide rails, which are arranged in parallel, and two first slide blocks, both of which are fixed to the bottom of the second guide rail.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention features a first guide rail and a first slide on a cutting table, and a second guide rail and a second slide on the first slide.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figures 1 to 5 As shown, Embodiment 1 of this utility model provides a controller PCB board cutting device, which can conveniently adjust the cutting angle and can also be used to cut curved edges. Specifically, it includes a cutting table 1, on which a cutting machine 2, a circular saw blade type cutting device, is fixedly mounted. Two parallel first guide rails 3 are also fixedly mounted on the cutting table 1, perpendicular to the axis of the circular saw blade. A first slide block 4 is slidably mounted on each first guide rail 3, and both first slide blocks 4 are fixedly connected to the same second guide rail 5, which is located above the first slide block 4. The length direction of the second guide rail 5 is perpendicular to the length direction of the first guide rail 3. The length direction of the second guide rail 5 is parallel to the axis of the circular saw blade.

[0031] A second slide block 6 is slidably mounted on the second guide rail 5, and the position of the second slide block 6 on the second guide rail 5 is adjustable. Specifically, the adjustment structure is as follows: a mounting plate is fixed to the end of the second slide block 6 furthest from the cutting machine 2, and a third adjusting rod 16 is threaded onto the mounting plate. One end of the third adjusting rod 16 is rotatably mounted on the second guide rail 5. Thus, rotating the third adjusting rod 16 adjusts the position of the second slide block 6 on the second guide rail 5, thereby adjusting the distance between the second slide block 6 and the cutting machine 2.

[0032] like Figure 1 and Figure 2 As shown, a disc 7 is rotatably mounted on the second slide block 6. A limiting frame 8 is fixed on the disc 7. The limiting frame 8 is L-shaped and has a double-layer structure. The lower layer is fixedly connected to the edge of the disc 7, and the upper layer is located above the disc 7, leaving a material feeding gap between them. The limiting frame 8 includes two limiting plates 9, which are located at the two ends of the L-shape and perpendicular to the disc 7. The planes on which the two limiting plates 9 are located are perpendicular. A clearance notch 10 is provided between the two limiting plates 9, which is located within the included angle of the L-shape. The two sides of the PCB board can respectively abut against the two limiting plates 9, so that one corner of the PCB board is in the clearance notch 10. Then, the disc 7 is rotated to bring the PCB board in the notch closer to the cutting machine 2. The first slide block 4 is slid along the first guide rail 3, allowing the cutting machine 2 to cut the corner of the PCB board. The cutting angle can be adjusted by rotating the disc 7.

[0033] Example 2:

[0034] Based on Embodiment 1, in order to maintain the position of the PCB board during PCB board cutting, this utility model also provides a clamping structure on the limiting frame 8, specifically including a fourth adjusting rod 17 threadedly installed on the limiting frame 8. Figure 5 As shown, a pressure plate 18 is fixed to one end of the fourth adjusting rod 17 located between the disc 7 and the limiting frame 8. A rubber pad is provided on the side of the pressure plate 18 near the disc 7. In this way, rotating the fourth adjusting rod 17 will lower the pressure plate 18, allowing the pressure plate 18 to press the PCB board onto the disc 7, thus preventing the PCB board from moving when cutting the PCB board.

[0035] Example 3:

[0036] Based on Embodiments 1 and 2, to facilitate adjustment and maintain the angle of the disc 7, this invention includes a rotating base 12 fixedly mounted on the second slide block 6, with an adjusting rod rotatably mounted on the rotating base 12. A ring of teeth 11 is formed on the circumferential surface of the disc 7. A gear 14, meshing with the teeth 11, is fixed to one end of the first adjusting rod 13 near the disc 7. Thus, rotating the second adjusting rod 15 drives the disc 7 to rotate via the gear 14. While this allows for precise adjustment of the disc 7's rotation angle, it is still necessary to fix the second adjusting rod 15 to prevent rotation and thus restrict the disc 7's rotation. Therefore, this invention also includes a second adjusting rod 15 threadedly fitted to the rotating base 12, with the end of the second adjusting rod 15 abutting against the first adjusting rod 13. Rotating the second adjusting rod 15 locks the first adjusting rod 13 onto the rotating base 12, thereby preventing the disc 7 from rotating.

[0037] In use, first, place the two sides of the PCB board against the two limiting plates 9 respectively. Then, rotate the fourth adjusting rod 17 to fix the PCB board on the disc 7. Next, rotate the first adjusting rod 13 to drive the disc 7 to rotate, turning the PCB board to a suitable angle. Then, rotate the second adjusting rod 15 to lock the disc 7. After that, rotate the third adjusting rod 16 to control the distance between the second slide 6, the disc 7, and the cutting machine 2, thereby adjusting the cutting depth of the PCB board. Finally, push the first slide 4 along the first guide rail 3 to allow the cutting machine 2 to cut the PCB board. When rounded corner cutting is required, simply rotate the first adjusting rod 13 during the cutting process to rotate the disc 7, and an arc edge will be cut on the PCB board.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
