Abstract

The invention provides a roller machining device, which is used for machining a roller. The roller machining device comprises a cutter, a cutter driving shaft, a bearing device, a guide rail and a numerical control module, wherein the cutter is arranged on the cutter driving shaft; the cutter driving shaft is used for driving the cutter to feed, the guiding direction of the guide rail is vertical to the feeding direction of the cutter; the bearing device is movably arranged on the guide rail; the roller is arranged on the bearing device, the central shaft of the roller is parallel to the guiding direction of the guide rail, and the bearing device is used for driving the roller to rotate around the central shaft of the roller; the numerical control module is used for controlling the feeding amount of the cutter, the movement speed of the bearing device and the rotation speed of the roller, so that the cutter spirally engraves the roller. In a process of spirally engraving the roller, the roller is expanded to be at a flat state, the path of the cutter is in a sine or cosine shape. According to the roller machining device disclosed by the invention, the cutter engraves the roller by utilizing a continuously machined spiral engraving method, so that the micro-structure machining with high speed and height change to the roller is realized.

Description

technical field [0001] The invention relates to a processing device, in particular to a drum processing device. Background technique [0002] In order to prevent moiré fringes from being generated in the backlight module, it is necessary to form a microstructure with varying heights on the brightness enhancement film in the backlight module. The microstructure on the brightness enhancement film is usually formed by roller transfer printing, and the microstructure with high and low changes on the roller is generally formed by the cut-in engraving method. However, the processing device equipped with the cut-in engraving method needs to engrave one microstructure before engraving another microstructure, so that the processing is discontinuous, and repeated positioning is required, resulting in slow processing speed and low processing accuracy, so it is not suitable for Processing of large drums. Contents of the invention [0003] In view of this, it is necessary to provide ...
