Problems solved by technology

[0006] In the traditional manufacturing technology, a single tool is used to cut micro-grooves on the surface of the roller. However, in the face of an increasing number of micro-grooves, not only the processing time cannot be reduced, but the wear rate of the diamond tool is also greatly increased.
Therefore, it is not only unfavorable for mass production, but also leads to an increase in the production cost of the roller.
Moreover, due to the rapid wear of the diamond cutter, the uniformity of the micro-groove structure on the surface of the roller will be affected, which in turn will affect the production of the optical brightness enhancement film.

Abstract

The invention discloses a device and a method for processing a roller micro groove. The device for processing the roller micro groove at least comprises: a cutter holder, wherein one side of the tool holder is at least provided with a plurality of cutter fixing openings; and a plurality of cutters which are fixedly arranged in the cutter fixing openings in a corresponding manner, wherein each cutter is provided with a knifing and a nose radius, the knifings are different from each other and the same goes for the nose radii, and these cutters can cut the surface of a roller simultaneously.

Description

technical field [0001] The invention relates to a processing device and a processing method of a roller, and in particular to a processing device and a processing method of a micro-groove of a roller. Background technique [0002] In the development of flat panel displays, the enlargement of display size is one of the important trends. Therefore, in response to the large-scale development of flat-panel displays, the manufacturing technology of large-scale backlight modules that provide backlight sources for display panels has also become the focus of research and development. [0003] In the backlight module of the liquid crystal display, the optical brightness enhancement film (Brightness Enhancement Film; BEF), commonly known as the prism sheet, is a very important component in the backlight module of today. However, the optical brightness enhancement film is quite expensive. In a backlight module, the cost of the optical brightness enhancement film accounts for about 40%...
