[0002] OCA optical adhesive is one of the important raw materials for touch screens. It is made by making optical acrylic adhesive without a substrate, and then laminating a layer of release film on the upper and lower bottom layers. It is a double-sided laminating tape without a substrate material. OCA optical adhesive needs to be cut during production and processing. The "high-precision OCA processing equipment cutting device" disclosed in the publication number "CN218639794U" has solved the technical disadvantages of difficult loading and unloading and maintenance, easy to generate bubbles and loose lamination. However, in actual use, cutting devices with similar structures still have many defects, such as Most of them support and move the OCA optical glue through rollers, and do not have the function of horizontally supporting the cutting part during operation. When the device is cutting the OCA optical glue, the cutting part will bend and deform due to pressure, thereby reducing the quality of the incision made by the device. In addition, most of them adopt an open operating structure. When cutting the OCA optical glue, suspended matter in the air will adhere to the incision, causing contamination of the OCA optical glue incision. For this reason, we have designed a high-precision OCA processing equipment cutting device to solve the above problems. Utility Model Content
