Abstract
Description
Technical Field
[0001] This invention relates to the field of polishing equipment technology, and in particular to a reciprocating polishing device for light guide plate cuts. Background Technology
[0002] Light guide plates are made of optical-grade acrylic / PC sheets and high-tech materials with extremely high reflectivity and no light absorption. They are commonly used in the LCD screens of laptops and are optical products that transform line light sources into surface light sources. During the production and processing of light guide plates, they need to be cut to change their size as needed. After cutting, the cut ends of the light guide plates need to be polished to meet the standards required for use.
[0003] For example, application number CN201822000340.0 discloses an edge grinding device for cutting a light guide plate, including a first base, a movable plate, a fixed plate, and a fixed platform. A second base is provided on one side of the first base, and a first groove is provided on the side of the second base away from the first base. A first slider is provided inside the first groove, and a first moving rod passes through the inside of the first slider. A first servo motor is provided at one end of the first moving rod. The movable plate is provided on the side of the first slider away from the first moving rod, and a moving roller is provided on the side of the movable plate away from the first slider. The moving roller is provided inside the roller groove. In this edge grinding device for cutting a light guide plate, starting the second servo motor drives the second moving rod to rotate, allowing the second moving rod to control the movement of the second slider. Then, starting the first motor drives the grinding block to rotate, thus allowing the grinding block to process and grind the edge of the light guide plate.
[0004] However, there are some shortcomings in the current design of light guide plate grinding equipment. When grinding light guide plates, the grinding equipment can only grind one group of light guide plates at a time. This processing method is inefficient and not suitable for large-scale light guide plate grinding. Summary of the Invention
