Camera protective film die-cutting device

Technical Field

The utility model relates to the technical field of protective film production, and more specifically to a camera protective film die-cutting device.

Background Art

The camera, also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, and real-time monitoring. In addition, people can also use it for various popular digital images, audio and video processing, etc. In the production process of the camera, a protective film is needed to protect the camera. In the production of camera protection, a die-cutting device is needed to die-cut the protective film.

The current camera protective film die-cutting device, such as the "Camera Protective Film Die-cutting Device" proposed in 202222990404.2, includes a load-bearing plate, a group of support columns are fixedly connected to the bottom surface of the load-bearing plate, a protective frame is installed on the upper surface of the load-bearing plate, and the inner wall of the protective frame is slidably connected to the mounting plate. The upper surface of the protective frame is fixedly inlaid with two driving mechanisms, and the output ends of the two driving mechanisms are fixedly connected to the upper surface of the mounting plate. It can be arranged through the coordination between the load-bearing plate, support columns, protective frame, mounting plate, driving mechanism, die-cutting tool, limit assembly, holding frame, die-cutting seat and load-bearing block. The driving mechanism can drive the mounting plate and the die-cutting tool to move, and can die-cut the protective film. The limit assembly can be used to facilitate the disassembly of the die-cutting tool, and at the same time, the die-cutting tool can be well fixed, which can ensure the stability of the die-cutting tool during use and avoid damage to the die-cutting tool.

The existing camera protective film die-cutting device disassembles the cutting tool through the installation mechanism. Although it can be more convenient to replace the cutting tool, in actual use, with the diversification of electronic products, the lens modules of different electronic products are also very different. At this time, lens modules of different shapes are required to adapt to different sizes. Lens modules of different shapes require the cutting tool to be replaced, but when replacing, the cutting tool is generally disassembled and replaced through the disassembly and assembly mechanism. This operation method is time-consuming, affects work efficiency to a certain extent, and is inconvenient to use. Therefore, there is an urgent need to improve the technology of the camera protective film die-cutting device structure to improve this equipment.

As the lens module of the electronic product changes, the lens protective film corresponding to its size needs to be cut. At this time, the cutting knife 15 needs to be replaced. The gear 18 can be released by pulling the L-shaped push rod 22, and then the connecting rod 17 can be rotated arbitrarily. The connecting rod 17 drives the turntable 12 to rotate through the shaft 13. After the rotation is completed, the L-shaped push rod 22 can be loosened, and the restoring elastic force generated by the second spring 21 drives the L-shaped push rod 22 to move against the gear 18 to lock it. There is no need to disassemble the cutting knife 15 for replacement. You only need to rotate the turntable 12, and the turntable 12 drives the cutting knife 15 of the corresponding specification to be located directly above the workbench 23.
