As an indispensable key material in modern display technology, optical instruments, and electronic equipment, the cutting quality of optical films not only affects the optical performance of the product but also directly impacts its lifespan and user experience.

[0003] According to the authorized announcement number CN212666239U, a cutting device for optical films is disclosed, including a cutting body, a rotating shaft disposed inside the cutting body, and a drive motor fixed to the side wall of the cutting body for driving the rotating shaft to rotate. A pressure roller is rotatably mounted on the side of the cutting body away from the rotating shaft, and a lower pressure roller is disposed above the pressure roller. A cylinder is mounted on the cutting body, and a bearing is rotatably connected to both ends of the lower pressure roller. The piston rod of the cylinder faces the pressure roller and is fixedly connected to the bearing.

[0004] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the prior art: In the aforementioned case, before the operator drives the cutting body to cut the optical film, the driving cylinder drives the lower pressure roller to press down onto the roller surface of the pressure roller to clamp the optical film, and then the cutting body is controlled to cut the optical film. However, during use, the operator needs to manually control the cutting distance of the optical film, affecting work efficiency and cutting accuracy.

[0005] Therefore, we propose an optical film equidistant cutting device that can automatically cut optical films at equal intervals and can automatically adjust the cutting distance of the optical film. Utility Model Content

[0012] As an optional solution to the technical solution of this application, the drive rod is rotatably connected to both sides of the mounting groove via bearings, and the servo motor is fixedly connected to the upper end of one side of the cutting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the optical film can be transported by an electric conveyor belt, and the servo motor can be controlled to drive the drive rod and cam to rotate.

[0018] Please see Figures 1-2 This utility model provides a technical solution: an optical film equidistant cutting device, including a conveying trough 1, an electric conveyor belt 11 arranged inside the conveying trough 1, a cutting frame 12 welded to the middle of the upper end of the conveying trough 1, a blade 13 vertically arranged on the bottom side of the cutting frame 12, and a driving mechanism for driving the blade 13 to reciprocate cutting. The driving mechanism includes a servo motor 22. An installation groove 14 is opened inside the cutting frame 12. A driving rod 2 is horizontally rotatably connected to the inner side of the installation groove 14. The shaft end of the servo motor 22 is fixedly connected to one end of the driving rod 2. The driving rod 2 is rotatably connected to both sides of the installation groove 14 through bearings. The servo motor 22 is fixedly connected to the upper end of one side of the cutting frame 12. Cams 21 are installed through and fixedly mounted on both sides of the driving rod 2. A guide plate 16 is horizontally fixedly mounted on one end of the blade 13 placed inside the installation groove 14. The cam 21 abuts against the upper surface of the guide plate 16. A guide groove 15 is horizontally opened through the middle of the inner wall of the bottom end of the installation groove 14. The blade 13 is slidably connected to the guide groove 15.

[0019] In this technical solution, the optical film can be conveyed by the electric conveyor belt 11. The servo motor 22 is controlled by the industrial control computer 27 to drive the drive rod 2 to rotate, thereby driving the two sets of cams 21 to rotate in the mounting groove 14. When the convex end of the cam 21 abuts against the upper surface of the guide plate 16, it can push the blade 13 on the bottom side of the guide plate 16 to move downward to cut the optical film on the surface of the electric conveyor belt 11. It should be noted that a pressure roller can be installed at the bottom of the cutting frame 12 for fixing the optical film during cutting.

[0020] In this embodiment, two sets of limiting rods 23 are vertically fixedly installed on the inner wall of the bottom end of the mounting groove 14. The two sets of limiting rods 23 vertically penetrate both ends of the guide plate 16 and are slidably connected to the guide plate 16. Springs 24 are provided at both ends of the lower surface of the guide plate 16, and the two sets of springs 24 are respectively sleeved on the outside of the two sets of limiting rods 23.

[0021] In this technical solution, when the drive rod 2 drives the cam 21 to rotate, causing the convex end of the cam 21 to move away from the guide plate 16, two sets of springs 24 are provided on the bottom side of the guide plate 16. The elastic force of the springs 24 can push the guide plate 16 to move upward, thereby driving the blade 13 to move upward and reset. Furthermore, the cam 21 reciprocates, which can reciprocate to perform equidistant cutting operations on the optical film on the upper surface of the electric conveyor belt 11 during the conveying process. The springs 24 are sleeved on the outside of the limiting rod 23, which can limit the springs 24 and improve the stability of the springs 24 and the guide plate 16.

[0022] In this embodiment, a control mechanism for controlling the cutting interval of the blade 13 includes a Hall sensor 25 and a magnet 26. The Hall sensor 25 is fixedly connected to the middle of the inner wall of the top of the mounting groove 14, and the magnet 26 is equidistantly installed on the outer side of the middle of the drive rod 2. The Hall sensor 25 and the magnet 26 correspond to each other. An industrial control computer 27 is fixedly connected to the lower side of the side of the cutting frame 12 where the servo motor 22 is installed.

[0023] In this technical solution, the drive rod 2 drives the cam 21 to rotate, which in turn drives the magnet 26 to rotate. When the magnet 26 rotates to the point where its upper end is aligned with the Hall sensor 25, the Hall sensor 25 can transmit data to the industrial control computer 27, thereby detecting the number of rotations of the drive rod 2. By controlling the speed of the servo motor 22, the rotation speed of the drive rod 2 can be controlled, further controlling the cutting interval of the blade 13, which facilitates the adjustment of the cutting distance of the optical film.

[0024] When using an optical film equidistant cutting device, the optical film is conveyed via an electric conveyor belt 11. An industrial control computer 27 controls a servo motor 22, which drives a drive rod 2 to rotate. This, in turn, causes two sets of cams 21 to rotate within the mounting groove 14. When the convex end of the cam 21 abuts against the upper surface of the guide plate 16, it pushes the blade 13 on the bottom side of the guide plate 16 downwards to cut the optical film on the surface of the electric conveyor belt 11. When the drive rod 2 drives the cam 21 to rotate, causing the convex end of the cam 21 to move away from the guide plate 16, two sets of springs 24 are installed on the bottom side of the guide plate 16. The spring force of the springs 24 pushes the guide plate... 16 moves upward, thereby driving the blade 13 to move upward and reset. Furthermore, the cam 21 reciprocates, enabling it to perform equidistant cutting operations on the optical film during the conveying process on the upper surface of the electric conveyor belt 11. While the drive rod 2 drives the cam 21 to rotate, it can also drive the magnet 26 to rotate. When the magnet 26 rotates to the upper end and aligns with the Hall sensor 25, the Hall sensor 25 can transmit data to the industrial control computer 27, thereby detecting the number of rotations and speed of the drive rod 2. By controlling the speed of the servo motor 22, the rotation speed of the drive rod 2 can be controlled, further controlling the cutting interval of the blade 13, making it convenient to adjust the cutting distance of the optical film according to the usage requirements.
