Description

Technical Field

[0001] This invention belongs to the field of optical thin film processing technology, and is particularly related to an optical thin film processing apparatus and processing method. Background Technology

[0002] After forming and stretching, optical films are typically wound up using film rollers before being slit. Slitting requires initially cutting the wound film into rectangular shapes, then further cutting it to predetermined sizes for use in manufacturing mobile phone displays, computer displays, and various filters. Currently, the initial cutting of optical films usually involves pulling the film wound on a single film roller to the cutting blade, then controlling the cutting blade to cut the film. This process requires multiple pulling and cutting operations to completely cut the film on the roller. For example, utility model patent application CN202022139529.5 discloses a plastic film cutting device, including a roller device, a first traction device, a cutting section, and a second traction device. It automatically cuts the film by pulling it to the cutting section without manual operation, thus improving cutting efficiency.
