Problems solved by technology

[0004] The deflection of the flexible substrate during the transportation process will cause wavy winding of the flexible substrate, ridges or uneven sides of the substrate, and even wrinkles or cracks
In addition, for high-precision flexible electronic products, because the flexible substrate is shifted during the transmission process, the accuracy conditions that can be provided in the process are limited, and the high-precision requirements cannot be met.
[0005] In addition, since the flexible substrate of the general roll-to-roll production line must be conveyed and turned by many transmission wheels during the transportation process, it is usually alternately sandwiched between these transmission wheels, so the upper and lower surfaces of the flexible substrate will interact with these transmission wheels. Contact, so that the upper and lower surfaces of the flexible substrate bear positive and reverse forces, this phenomenon may cause the flexible substrate to wrinkle or even crack

Abstract

A conveyor apparatus including a control module, an unwinding module, at least one tension sensing module, and a rewinding module is provided. The tension sensing module includes a load cell disposed between a set of rollers. An objet is conveyed along a conveying direction perpendicular to an axis of the roller. A wrap angle is formed by the object and the roller with a fulcrum of the loadi cell served as a center, and the wrap angle is less than 180 DEG . The rewinding and unwinding modules have different actuating units electrically connected to the control module respectively, such that the object is wound or unwound by the rewinding and the unwinding modules.

Description

technical field [0001] The invention relates to a transmission device. Background technique [0002] When the thickness of the glass drops to a certain level, it can be bent to form a flexible glass, which has the characteristics of bendability and high hardness, and can be applied to the flat substrate of electronic paper (e-Paper), the protective cover in the photovoltaic module, Contact sensors, solid-state lighting and electronic devices, etc. The material of the flexible substrate can be glass, polymer or metal. [0003] Currently, thin glass can be transported using a roll-to-roll method. Although the flexible glass has a certain degree of flexibility under the ultra-thin thickness, it still retains the hard and brittle nature of the material. The strength of the flexible glass may cause stress concentration due to surface defects or scratches Decrease 2 to 4 times. Any unstable delivery force or drag and torque on the flexible glass may cause the thin glass to bre...
