[0002] The light guide plate is a high-tech product that converts a line light source into a surface light source. It has a plate-like structure and is usually processed by cutting, milling and other processing steps according to the needs of use. Different processes require corresponding processing equipment to operate. For example, during cutting, the light guide plate is punched and cut by a cutter to cut it into the required size. The cut light guide plate usually needs to be milled by a milling device to make its cut smooth. However, the existing light guide plates are manually transferred during the processing between various processes. For example, the light guide plate to be cut is placed on a cutting machine, and then the cutting machine is started for cutting. After cutting, the light guide plate is manually removed from the cutting machine, and then the angle or direction is changed and placed on the milling equipment for milling. The operation is cumbersome, labor-intensive, and increases production costs.
