Abstract
The present invention relates to a hole processing apparatus and processing method for optical films. According to an aspect of the present invention, there is provided a hole processing apparatus for optical films, comprising: a clamping unit for fixing a plurality of sheets of optical films in the state of being stacked; and a processing unit for performing a hole operation in predetermined regions of the optical films to sequentially pass through the plurality of sheets of optical films along the stack direction, in a state where the optical films are fixed to the clamping portion, wherein the processing unit, during hole operations, includes a drill unit provided to perform a first hole processing operation and a bite unit provided to perform a second hole operation in a first hole operation region.
Description
technical field [0001] The present invention relates to a hole processing device and a hole processing method for optical films. [0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2018-0134926 filed on November 6, 2018, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] In order to process the holes in the polarizing plate, the polarizing plate is fixed to the device, the processing position of the hole is determined by a camera, and then the hole processing is performed using a laser. [0004] At this time, since the hole processing of the polarizing plate is performed one by one, mass production takes a lot of time, and depending on the raw material, some materials are damaged at the time of laser processing, so that some products are also difficult to be processed, and thus there are difficulties in conventionally to apply hole machining problems.
