Problems solved by technology

[0003] However, because this method is extended from the traditional light guide plate, there are many kinds of light guide plate with its own development, such as the light guide plate with many bumps and pits on the surface, so it can be done with ordinary scratches. When scribing, the pit cannot be effectively scribbled, resulting in uneven cross-section or rough appearance when the light guide plate is opened.

Abstract

The invention discloses a cutting tool bit for light guide plates. The cutting tool bit comprises three main tool bits; a wedge-shaped main blade is arranged at the bottom of each main tool bit; a connecting rod is arranged between every two adjacent main tool bits; and ribs are arranged on the opposite side surfaces of every two adjacent main tool bits. The cutting tool bit further comprises sliding blocks arranged between every two adjacent main tool bits; and first guide grooves matched with the ribs are formed in two sides of the sliding blocks. The cutting tool bit further comprises screws; the bottoms of the screws are connected with the tops of the sliding blocks; the screws penetrate through the connecting rods; and the tops of the screws are in threaded connection with adjusting nuts. With two groups of tool bits, one group is retractable, cutting seams in the surfaces of the light guide plates can be effectively cut in place, and the conditions that the edges of the light guide plates are coarse and irregular when the light guide plates are split due to positions which are not cut can be avoided.

Description

technical field [0001] The invention relates to a cutter head for cutting a light guide plate. Background technique [0002] Since the light guide plate is similar to an acrylic plate, there are many ways to cut the light guide plate, including laser or direct cutting, but the current relatively low-cost or relatively simple cutting method is to draw a line on the light guide plate, and then press on both sides. Disconnect the light guide plate like scratching glass. [0003] However, because this method is extended from the traditional light guide plate, there are many kinds of light guide plate with its own development, such as the light guide plate with many bumps and pits on the surface, so it can be done with ordinary scratches. When scribing, the pits cannot be effectively scribbled, resulting in uneven cross-sections or roughness when the light guide plate is opened. Contents of the invention [0004] The object of the present invention is to overcome the above-me...
