Device for polishing side edge of circular light guide plate

The invention relates to the technical field of polishing of light guide plates, in particular to a device for polishing the side edge of a circular light guide plate. The device includes a base and adevice body; a through groove is formed in the middle part of the top of the base, a buffer plate penetrates through the through groove internally, the device body is arranged at the upper end of thebuffer plate, a limiting plate is arranged at the lower end of the buffer plate, and the left end and the right end of the limiting plate are respectively and slidably connected with the inner wall of the base. According to the device for polishing the side edge of the circular light guide plate, through the design and use of a series of structures, a damping function is achieved in the use process of the device, the effect of shock absorption for the vibration generated during the operation of the device is improved, the service life of the device is prolonged, the use efficiency of the device is improved, and the pr
