Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board cutting technology, and in particular to a PCB board forming and cutting device. Background Technology
[0002] In PCB manufacturing, raw materials are typically large-sized PCB boards (such as panels). After processes like printing and electroplating, these boards need to be shaped and cut. At this stage, a cutting device is used to cut the boards into specific shapes (such as rectangles, circles, or complex shapes) according to design drawings to accommodate subsequent installation and assembly. During production, the PCB boards may require further trimming or removal of unwanted parts. This cutting device can precisely remove edges or excess portions, ensuring the circuit board meets design requirements, avoiding unnecessary material waste, and improving production efficiency.
[0003] However, some existing PCB board forming and cutting devices typically place the PCB board directly on top of the worktable and then start the device to cut and shape the PCB board. However, they do not take into account that the PCB board will be subjected to force from the cutting blade during the cutting process, thus requiring the PCB board to be clamped and fixed.
[0004] Therefore, a PCB board forming and cutting device is proposed to address the above problems. Utility Model Content

The threaded rods are connected to moving frames with external threads. The bottom of the moving frames is provided with cutting blades. The middle of the lifting plates is provided with sliding holes two. The top front and rear sides of the lifting plates are fixedly connected to support plates.

[0023] 1. In this utility model, the PCB board to be clamped and fixed is first placed on the top of the workbench. Then, motor one is started, and the output end of motor one drives the output shaft to rotate. When the output shaft rotates, it drives the rotating plate to move.

This can prevent the PCB board from shaking during the cutting process, thereby improving the stability of the device.
[0024] 2. In this utility model, after the PCB board is clamped and fixed, the electric guide rail can be activated, causing the sliding block to move.

As the threaded rod rotates, it will drive the moving frame to move. When the moving frame moves to the appropriate position, the cutting blade is activated to cut the PCB board. This allows the device to cut different positions on the PCB board, thereby improving the flexibility of the device. Attached Figure Description

[0031] 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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a PCB board forming and cutting device, including a worktable 1. The worktable 1 serves as the basic support structure of the device, used to support the PCB board to be cut and other mechanical components. A mounting plate 2 is fixedly connected to the bottom of the worktable 1, and the mounting plate 2 fixes a drive assembly, connecting a motor 3 to the worktable 1 to ensure stable operation of the drive assembly. A drive assembly for providing power to the device is fixedly connected to the top of the mounting plate 2, and a rotating plate 5 is fixedly connected to the top of the drive assembly. The drive assembly includes a motor 3, which provides rotational power, driving an output shaft 4 to rotate, thereby moving the rotating plate 5. The bottom of the motor 3 is fixedly connected to the top of the mounting plate 2, and the output end of the motor 3 is fixedly connected to the output shaft 4. The output shaft 4 transmits the rotational power of the motor 3 to the rotating plate 5, causing it to produce circular motion. The middle of the rotating plate 5 is fixedly connected to the top of the output shaft 4. The rotating plate 5 converts the rotation of the motor 3 into the reciprocating motion of the connecting plate 7 through circular motion, indirectly driving the sliding plate 9 to move horizontally. Fixed posts 6 are fixedly connected to the top front and rear sides of the rotating plate 5. The fixed posts 6 serve as the connection fulcrum between the rotating plate 5 and the connecting plate 7, transmitting motion and limiting the range of motion of the connecting plate 7. The connecting plates 7 are rotatably connected to the outside of the two fixed posts 6. The connecting plates 7 convert the circular motion of the rotating plate 5 into the horizontal linear motion of the sliding plate 9, thereby realizing the lateral position adjustment of the clamping mechanism.
[0033] The workbench 1 has guide components fixedly connected to its interior front and rear sides. Each guide component includes two guide rods 8, which provide linear guidance for the sliding plate 9, ensuring stable horizontal sliding and preventing deviation. The exterior of the two guide rods 8 is fixedly connected to the interior front and rear sides of the workbench 1. Sliding plates 9 are slidably connected to the left and right sides of each guide component, with their middle sections slidably connected to the exterior left and right sides of the two guide rods 8, respectively. Guided by the guide rods 8, the sliding plates 9 carry the electric push rod 10 and the clamping plate 11, allowing for horizontal movement and adjusting the clamping position. Connecting posts 22 are fixedly connected to the bottom of each sliding plate 9, connecting the connecting plate 7 and the sliding plate 9, transmitting motion and maintaining structural stability. The other end of the connecting plate 7 is rotatably connected to the exterior of the connecting post 22. Electric push rods 10 are fixedly connected to the top front and rear sides of the sliding plate 9, driving the clamping plate 11 to vertically lift and lower, clamping or releasing the PCB board and ensuring its fixation during cutting. The output end of the electric push rod 10 is fixedly connected to a clamping plate 11. The clamping plate 11 directly contacts and fixes the PCB board, and the clamping force is provided by the thrust of the electric push rod 10 to prevent the board from shaking during cutting. Two sliding holes 12 are provided on both the front and rear sides of the top of the worktable 1. The sliding holes 12 guide the vertical movement of the electric push rod 10, ensuring its stable vertical lifting and lowering. The top of the electric push rod 10 is slidably connected inside the sliding hole 12.
[0034] Reference Figure 1 and Figure 4The worktable 1 has two fixed moving components on its top front and rear sides for adjusting the cutting position. Each moving component includes two electric guide rails 13. The electric guide rails 13 drive sliding blocks 14 to move horizontally, adjusting the lateral position of the electric push rod 15 to achieve coarse adjustment of the cutting position. The bottoms of the two electric guide rails 13 are fixedly connected to the top front and rear sides of the worktable 1, respectively. Sliding blocks 14 are slidably connected to the outside of each electric guide rail 13. The sliding blocks 14 slide along the electric guide rails 13, carrying the electric push rod 15 and subsequent cutting components for lateral displacement. The top of the moving components has the electric push rod 15 fixedly connected, and the bottom of the electric push rod 15 is fixedly connected to the top of the sliding blocks 14. The electric push rod 15 drives the lifting plate 16 to move vertically, adjusting the height of the cutting blade 20 to accommodate PCB boards of different thicknesses. The output ends of the two electric push rods 15 are fixedly connected to the lifting plate 16, which carries the motor 17, threaded rod 18, moving frame 19, and cutting blade 20. The cutting height is adjusted by the movement of the electric push rods 15. A second motor 17 is fixedly connected to the top rear side of the lifting plate 16. The second motor 17 provides rotational power, driving the threaded rod 18 to rotate, which in turn drives the moving frame 19 to move horizontally. The output end of the second motor 17 is fixedly connected to the threaded rod 18, which converts the rotation of the second motor 17 into the horizontal linear motion of the moving frame 19, achieving precise lateral positioning of the cutting blade 20. The external thread of the threaded rod 18 connects to the moving frame 19, which slides along the threaded rod 18 and the sliding hole 21, carrying the cutting blade 20 for lateral movement and adjusting the cutting position. The cutting blade 20 is located at the bottom of the moving frame 19, directly cutting the PCB board. Precise cutting is achieved through the drive of the second motor 17 and the threaded rod 18. The second sliding hole 21 is provided in the middle of the lifting plate 16, guiding the horizontal movement of the moving frame 19 and ensuring that the cutting blade 20 moves in a straight line. The bottom of the movable frame 19 is slidably connected to the inside of the sliding hole 21. Support plates are fixedly connected to the front and rear sides of the top of the lifting plate 16. The support plates support the two ends of the threaded rod 18 to ensure its stable rotation and prevent deviation during movement. The external rotatable connection of the threaded rod 18 is to the top of the two support plates. Support legs are fixedly connected to the four corners of the bottom of the worktable 1, and anti-slip pads are provided on the bottom of the support legs.
[0035] Working Principle: First, the PCB board to be cut is placed stably on top of the worktable 1. Then, motor 3 is started, and its output end drives the output shaft 4 to rotate. Since the output shaft 4 is fixedly connected to the rotating plate 5, the rotating plate 5 moves in a circular motion. The fixed posts 6 on the front and rear sides of the top of the rotating plate 5 also move in a circular motion, driving the connecting plate 7, which is externally rotatably connected to it, to move. The other end of the connecting plate 7 is rotatably connected to the connecting post 22 fixed at the bottom of the sliding plate 9, thereby causing the sliding plate 9 to slide outside the guide rod 8 as the connecting plate 7 moves. When the sliding plate 9 moves to the appropriate position, the electric push rod 10, which is fixedly connected to the front and rear sides of the top of the sliding plate 9, is activated. Its output end drives the clamping plate 11 to descend until the clamping plate 11 is in close contact with the PCB board, firmly clamping and fixing the PCB board on the worktable 1 to prevent it from shaking during the cutting process.
[0036] After the PCB board is clamped and fixed, the cutting and position adjustment process begins. First, a rough adjustment of the cutting position is performed. The electric guide rail 13 is activated, driving the sliding block 14 to move horizontally externally. Since the top of the sliding block 14 is fixedly connected to the electric push rod 15, the electric push rod 15 moves synchronously. It is moved to a roughly suitable position according to the cutting requirements, completing the initial adjustment. Next, the cutting height is adjusted. Once the electric push rod 15 has moved to the appropriate position, it is activated. Its output end drives the lifting plate 16 to descend. The lifting plate 16 carries the motor 17, threaded rod 18, moving frame 19, and cutting blade 20 as it descends together. The cutting blade 20 is adjusted to a suitable height according to the PCB board thickness. Then, the cutting position is finely adjusted. Motor 17 is started, and its output drives the threaded rod 18 to rotate. Since the moving frame 19 is threadedly connected to the threaded rod 18 and its bottom slides within the sliding hole 21, the rotation of the threaded rod 18 causes the moving frame 19 to move horizontally along the threaded rod 18 and the sliding hole 21. Precise positioning of the cutting blade 20 is achieved by precisely controlling the rotation of motor 17. Finally, the PCB board is cut. After the moving frame 19 moves to the appropriate position, the cutting blade 20 is started to rotate at high speed to cut the PCB board. During the cutting process, the cutting position can be finely adjusted again via the electric guide rail 13, or the cutting height can be finely adjusted via the electric push rod 15, to ensure cutting accuracy and quality.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
