Description

Technical Field

[0001] This utility model relates to the field of optical thin film die-cutting technology, specifically a high-precision optical thin film die-cutting device. Background Technology

[0002] Optical thin films are thin-film materials with specific optical properties, commonly used in optical devices, optical coatings, and optical filters. The main function of optical thin films is to control the transmission, reflection, and transmission of light to achieve specific optical functions. Die-cutting equipment, also known as a die-cutting machine, is used to cut materials, making optical thin films easier for subsequent processing and use.

[0003] While existing technologies use a template to secure the film at the four corners of the cutting plate during the cutting process, preventing film displacement, reducing errors, and improving accuracy, adjustments to the cutting direction at specific angles require fine-tuning. This not only takes longer for operators but also depends heavily on their experience and skill, making it inconvenient. Adjusting the cutting spacing necessitates stopping the machine, which is cumbersome, time-consuming, and labor-intensive, resulting in low efficiency. Furthermore, the traditional method of pushing the film out via a conveyor belt for cutting is prone to inconsistent feed rates due to friction with the conveyor belt and variations in the conveyor belt's transfer ratio, leading to compromised cutting accuracy.

[0004] Therefore, a high-precision optical thin film die-cutting device is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision optical thin film die-cutting device to solve the problems mentioned in the background art, such as the cumbersome adjustment method, long adjustment time, and poor transfer accuracy caused by the transfer ratio of the conveying kun accompanying the film transport.

[0007] Preferably, a support plate is fixedly installed on the top surface of the mounting component, a guide is fixedly installed on the bottom surface of the support plate, a first rotating wheel is rotatably installed on the inner wall of the mounting component via a bearing sleeve, a first rotating roller is rotatably installed on the inner wall of the mounting component via a bearing seat, a bearing sleeve is fixedly opened on the side of the mounting component, a second driven wheel is fixedly installed on the inner wall of the bearing sleeve, a second rotating wheel is fixedly installed on the end face of the second driven wheel, and a second rotating roller is rotatably installed on the side of the mounting component via a bearing seat.

[0009] Preferably, a connecting plate is fixedly installed on the side of the mounting block, a first cylinder is fixedly installed on the side of the connecting plate, a slider is fixedly installed on the end face of the push rod of the first cylinder, and a through hole is fixedly opened on the side of the slider, with the inner wall of the through hole slidably connected to the side of the guide rail.

[0010] Preferably, the cutting angle adjustment mechanism includes a servo motor. The side of the servo motor is fixedly connected to the top surface of the slider via a fixing plate. A first gear is fixedly installed on the side of the servo motor. A placement plate is fixedly installed on the side of the slider. A scale plate is fixedly installed on the side of the placement plate. A through hole is fixedly opened on the side of the placement plate. A connecting rod is rotatably installed on the inner wall of the through hole via a bearing sleeve.

[0011] Preferably, a second gear is fixedly mounted on the side of the connecting rod, the tooth surface of the second gear meshing with the tooth surface of the first gear, a pointer is fixedly mounted on the side of the connecting rod, a base plate is fixedly mounted on the end face of the connecting rod, and a second cylinder is fixedly mounted on the side of the base plate via a fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) In use, this high-precision optical film die-cutting device first passes the optical film through the guide, then the drive motor is turned on, which drives the first rotating wheel to rotate and move the optical film forward. The second cylinder is turned on to push the connecting rod and the cutting blade to cut the optical film. The remaining section of the optical film pushes the cut optical film to the inner wall of the second rotating rod and the second rotating roller. At the same time, the motor wheel rotates, which drives the belt to rotate and then the second driven wheel and the third driven wheel to rotate. The guide ring limits the rotation, and then drives the second rotating wheel to rotate and move the cut optical film out of the equipment, completing the cutting operation. It can effectively move the optical film through the rotating wheel and the rotating roller, ensuring that the film will not have different feed lengths due to inconsistent rotation ratios, thus improving the cutting accuracy.

[0015] 2) When the cutting spacing and cutting angle need to be adjusted, the servo motor drives the first gear to rotate, which in turn drives the second gear to rotate, causing the connecting rod and the base plate to deflect. This, in turn, causes the cutting blade mounted on the base plate to deflect, and the adjustment angle can be determined by the scale plate to change the feed angle of the cutting blade. When the cutting length of the optical film needs to be adjusted, the first cylinder is activated, and the push rod pushes the slider sleeved on the side of the guide rail to move, which in turn drives the cutting angle adjustment mechanism mounted on the side of the slider to move, thereby adjusting the position of the cutting point of the cutting blade and thus adjusting the length of the optical film being cut. This achieves precise adjustment and control of the cutting angle and cutting length, improving the application scenarios of the device. Attached Figure Description
