Variable conveyor belt unit for optical sheet loading

Abstract

The present invention relates to a variable conveyer belt device used for optical plate loading. The variable conveyer belt device used for the optical plate loading comprises a frame, a conveyer belt used for placing an optical plate, a driving mechanism connected with the above frame and comprising a plurality of variable rollers for supporting the above conveyer belt; a shifting mechanism connected with the plurality of variable rollers of the above driving mechanism to prompt the above plurality of variable rollers to move towards the above frame. The above optical plate is shifted to a loading position with the help of the above conveyer belt, and the above shifting mechanism enables the plurality of variable rollers to act to change the above conveyer belt. The variable rollers at the loading position move towards the direction reverse to the movement direction of the above optical plate, at the same time, the above conveyer belt is reeled to place the above optical plate at the loading position in statu quo.

Description

technical field [0001] The present invention relates to a conveyor belt device (CONVEYOR APPARATUS) for transferring an optical sheet in order to mount the optical sheet on a display glass panel of LCD, PDP, LED, etc. Background technique [0002] In general, optical sheets are mounted or laminated on display glass panels of LCDs, PDPs, LEDs, etc. for light refraction, reflection, and diffusion, and light is guided using its optical properties. [0003] In this case, in order to load the optical sheet on the glass panel, when the optical sheet is transferred and loaded by the conveyor belt, the glass panel is usually arranged at the lower part of the conveyor belt, that is, the loading position, and the optical sheet transferred by the above conveyor belt is The loading position hangs downward from the front end of the optical sheet to be in contact with the glass panel. [0004] In this state, the above-mentioned optical sheet is pushed forward by the conveyor belt and loa...

Problems solved by technology

[0004] In this state, the above-mentioned optical sheet is pushed forward by the conveyor belt and loaded onto the glass panel. At this time, the optical sheet is pushed while the above-mentioned optical sheet is in contact with the glass panel so that the contact surface of the optical sheet and the glass panel is in the optical contact surface. Scraping occurs when the sheet moves, resulting in scratches on the contact surface between the optical sheet and the glass panel, that is, damage such as scratches that reduce product quality or increase product defect rates
