[0029] Embodiment 1: An efficient cutting device for FPC, comprising a bottom plate 1, a support frame 2 is fixedly connected to the middle of the top of the bottom plate 1, a motor 3 is fixedly connected to the front end of the support frame 2, a rotating rod 4 is fixedly connected to the driving end of the motor 3, a rotating disk 5 is fixedly connected to the rear end of the rotating rod 4, a rotating shaft 6 is rotatably connected to the outer side of the right end of the rotating disk 5, a connecting rod 7 is fixedly connected to the bottom end of the rotating shaft 6, the bottom end of the connecting rod 7 is connected to a sliding plate 9 through a hinge 8, the inner walls of the left and right ends of the sliding plate 9 are slidably connected to the outer wall of the sliding rod 11, the top of the cutting knife 10 is fixedly connected to the bottom end of the sliding plate 9, the inner walls of the left and right ends of the bottom plate 1 are fixedly connected to the sliding rod 11, and a cutting groove 12 is provided on the inner wall of the middle of the top of the bottom plate 1;
[0030] Specifically, by placing the FPC on the base plate 1 and starting the motor 3, the rotating rod 4 is driven to rotate, and then the rotating disk 5 is driven to rotate. Through the rotation of the rotating disk 5, the rotating shaft 6 is driven to rotate along with the rotating disk 5 on the outside of the rotating disk 5. The rotating shaft 6 is connected to the connecting rod 7, and the connecting rod 7 is connected to the sliding plate 9 through the hinge 8. When the rotating disk 5 rotates, the sliding plate 9 can be driven to move, and the sliding plate 9 slides on the sliding rod 11, so that the movement of the sliding plate 9 tends to move up and down, driving the cutting knife 10 on the sliding plate 9 to move up and down quickly, thereby improving the efficiency of FPC cutting.
[0031] Embodiment 2: The left and right ends of the bottom plate 1 are fixedly connected to a fixing frame 13, an electric push rod 14 is fixedly connected to the inner wall of the middle part of the top of the fixing frame 13, and the driving end of the electric push rod 14 is fixedly connected to a connecting plate 15, and the front and rear ends of the connecting plate 15 are slidably connected to the inner wall of the fixing frame 13, and the front and rear sides of the bottom end of the connecting plate 15 are fixedly connected to a supporting plate 16, and the bottom end of the supporting plate 16 is fixedly connected to a fixing block 17, and the outer wall of the fixing block 17 is slidably connected to a fixing seat 18, and the fixing block 17 is connected to the inner wall of the fixing seat 18 through a spring 19, one end of the spring 19 is connected to the fixing block 17, and the other end of the spring 19 is connected to the inner wall of the fixing seat 18, and the top of the anti-slip pad 20 is fixedly connected to the bottom end of the fixing seat 18;
[0032] Specifically, during cutting, the electric push rod 14 is started to drive the connecting plate 15 to move downward, thereby driving the supporting plate 16 to move downward. The movement of the supporting plate 16 drives the fixing seat 18 on the fixing block 17 to fix the FPC. The spring 19 can prevent excessive pressure from damaging the FPC. The anti-slip pad 20 can improve the anti-slip property of the FPC when it is fixed. The FPC can be fixed when it is cut, thereby improving the effect of FPC cutting.
[0033] As one of the optimized structural designs for Example 1, Figure 1-Figure 4 As shown, the front end of the rotating disk 5 is rotatably connected to the inner wall of the support frame 2, which can improve the rotation stability of the rotating disk 5. The cutting knife 10 is matched with the cutting groove 12, which is convenient for cutting the FPC.
[0034] Working principle: First, by placing the FPC on the bottom plate 1, the motor 3 is started to drive the rotating rod 4 to rotate, and then the rotating disk 5 is driven to rotate. The rotating disk 5 rotates, thereby driving the rotating shaft 6 on the outside of the rotating disk 5 to rotate with the rotating disk 5. The rotating shaft 6 is connected to the connecting rod 7, and the connecting rod 7 is connected to the sliding plate 9 through the hinge 8. When the rotating disk 5 rotates, the sliding plate 9 can be driven to move, and the sliding plate 9 slides on the sliding rod 11, so that the movement of the sliding plate 9 tends to move up and down, driving the cutting on the sliding plate 9 The knife 10 moves up and down quickly, which improves the efficiency of FPC cutting. When cutting, the electric push rod 14 is started to drive the connecting plate 15 to move downward, and then the support plate 16 is driven to move downward. The movement of the support plate 16 drives the fixing seat 18 on the fixing block 17 to fix the FPC. The spring 19 can prevent excessive pressure from damaging the FPC. The anti-skid pad 20 can improve the anti-skid property of the FPC when it is fixed. When the FPC is cut, the FPC can be fixed, thereby improving the effect of FPC cutting.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
