Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board manufacturing technology, and in particular to a shearing device for flexible circuit board manufacturing. Background Technology

[0002] Flexible printed circuit boards (PCBs) are printed circuits made of flexible insulating substrates. They have many advantages that rigid PCBs do not have. They can be bent, rolled, and folded freely, arranged arbitrarily according to spatial layout requirements, and moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.

[0003] However, in the existing technology, during the shearing process of flexible circuit boards, a conveyor is needed to transport the flexible circuit board to the lower end of the shearing blade. However, since the flexible circuit board itself is thin, it is often easily disturbed by airflow and human factors during the conveying process, causing the flexible circuit board to deviate, which in turn causes errors in the shearing process, reducing the production efficiency and quality of flexible circuit boards. Therefore, this application provides a shearing device for flexible circuit board production to meet the requirements. Utility Model Content

[0028] like Figures 1-5As shown, an embodiment of this utility model provides a shearing device for flexible circuit board production, including: a mounting frame 1, which is concave; a support platform 6 is fixedly connected to the middle of the upper end of the mounting frame 1; widening strips 22 are fixedly connected to both sides of the support platform 6; leveling rollers 2 are rotatably connected to both side walls of the mounting frame 1; springs 3 are arranged around both ends of the side walls of the leveling rollers 2; one end of each spring 3 is fixed to both sides of the inner wall of the mounting frame 1; and the other end of each spring 3 is fixedly connected to a centering plate 4.

When the second rotating shaft 13 rotates, it drives the first rotating shaft 12 and the third rotating shaft 15 to rotate via the first and second chain sprocket sets. The rotation of the second rotating shaft 13, in turn, drives the leveling roller 2 to rotate via the conveyor belt structure. When the flexible circuit board passes between the two sets of centering plates 4, both ends of the flexible circuit board abut against the multiple sets of movable rollers 5 on the two sets of centering plates 4. At this time, the two sets of springs... The flexible circuit board is compressed and deformed by the centering plate 4. When the leveling roller 2 rotates, its lower surface comes into contact with the upper surface of the flexible circuit board. Due to the friction, the flexible circuit board moves towards the cutting mechanism when the leveling roller 2 rotates. Multiple sets of movable rollers 5 rotate and cooperate to transport the flexible circuit board and level its surface. In addition, the two sets of centering plates 4 cooperate to limit the position of the flexible circuit board and prevent movement deviation, thereby reducing the error in the shearing process and improving the production efficiency and quality of the flexible circuit board.

[0029] like Figures 1-5As shown, in this embodiment, the cutting mechanism includes a shearing blade 9, two vertical plates 21, and a servo motor 14. The servo motor 14 is fixedly mounted on a set of vertical plates 21. The output end of the servo motor 14 passes through a set of vertical plates 21 and is fixedly mounted with a second rotating shaft 13. The second rotating shaft 13 is connected to a first rotating shaft 12 via a first chain and sprocket set. Both ends of the first rotating shaft 12 are fixedly connected with circular cams 11. One side of each of the two circular cams 11, away from the center, is rotatably connected with a connecting rod 8. The other ends of the two connecting rods 8 are rotatably connected to both ends of the shearing blade 9. One side of the shearing blade 9, near the two sides, is slidably connected with a slide rail via two sets of slide grooves. One side of each of the two slide rails is fixedly mounted with a fixing column 10. The lower ends of the two fixing columns 10 are fixedly connected to the upper end of the mounting frame 1. The upper end of the mounting frame 1, located on both sides of the support platform 6, is provided with mounting holes 7. The two connecting rods 8 are respectively disposed inside the two mounting holes 7. The second rotating shaft 13 is connected to the third rotating shaft 15 via the second chain and sprocket set.

Two rotating rollers 18 are rotatably connected between the two vertical plates 21. The tops of the two rotating rollers 18 are respectively located in the two square holes 17. The tops of the two rotating rollers 18 are flush with the upper surface of the support platform 6. The upper and lower ends of the vertical plate 21 are fixed to the interior of the mounting frame 1. The collection box 20 is provided with a handle on the side away from the inclined end 19. The upper ends of both sides of the mounting frame 1 are provided with bevels. The upper and lower ends of the multiple sets of movable rollers 5 are provided with rounded chamfers. The conveyor wheel 16 is provided with multiple sets of weight-reducing holes. When the circular cam 11 rotates, it drives the two sets of connecting rods 8 to rotate, which further drives the shearing blades 9 to move up and down along the guide rail to periodically cut the flexible circuit board. The third rotating shaft 15 drives the conveyor wheel 16 to rotate. The conveyor wheel 16 and the lower set of rotating rollers 18 cooperate to transport the cut flexible circuit board. After passing through another set of rotating rollers 18, the flexible circuit board slides down the inclined end 19 into the collection box 20, which can complete the collection of the cut flexible circuit board, making it convenient for sorting and further processing.

[0030] The technical solution provided by this utility model first involves placing a flexible circuit board on a support platform 6. By starting a servo motor 14, the output of the servo motor 14 rotates, further driving the second rotating shaft 13 to rotate. When the second rotating shaft 13 rotates, it drives the first rotating shaft 12 and the third rotating shaft 15 to rotate via the first and second chain sprocket sets. The rotation of the second rotating shaft 13, in turn, drives the leveling roller 2 to rotate via a conveyor belt structure. When the flexible circuit board passes between two sets of centering plates 4, both ends of the flexible circuit board engage with multiple sets of movable rollers 5 on the two sets of centering plates 4. When the two sets of springs 3 come into contact, they are compressed and deformed by the centering plate 4. When the leveling roller 2 rotates, its lower surface comes into contact with the upper surface of the flexible circuit board. Due to the friction, the leveling roller 2 rotates and drives the flexible circuit board to move closer to the cutting mechanism. Multiple sets of movable rollers 5 rotate and cooperate to transport the flexible circuit board and level its surface. The two sets of centering plates 4 cooperate to limit the position of the flexible circuit board and prevent movement deviation, thereby reducing the error in the shearing process and improving the production efficiency and quality of the flexible circuit board.

[0031] When the circular cam 11 rotates, it drives the two sets of connecting rods 8 to rotate, which in turn drives the shearing blade 9 to move up and down along the guide rail, periodically cutting the flexible circuit board. Meanwhile, the third rotating shaft 15 drives the conveyor wheel 16 to rotate. The conveyor wheel 16 and a set of rotating rollers 18 at its lower end cooperate to transport the cut flexible circuit board. After passing through another set of rotating rollers 18, the flexible circuit board slides down the inclined end 19 into the collection box 20, thus completing the collection of the cut flexible circuit board for easy sorting and further processing.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.
