Problems solved by technology

Although reducing the speed of the winding roller and unwinding roller can prevent wrinkles, it will also lead to a decrease in production capacity
The second method is to reduce the tension of the long-meter base material. However, if the tension is reduced, it is easy to make the long-meter base material sag, and even cause the base material to fall off during winding.

[0022] figure 1 A side view of the substrate transport system according to the first embodiment of the present invention is shown. Such as figure 1 As shown, in this embodiment, the substrate transfer system may include a substrate transfer device 100 , a winding shaft 200 and a wind pressure providing device 300 . The substrate transfer device 100 can transfer the flexible substrate 400 toward the winding shaft 200 . In other words, the substrate 400 can be transferred from the substrate transfer device 100 to the winding shaft 200 along the transfer direction D1 shown in the figure. The winding shaft 200 can wind up the substrate 400 from the substrate transfer device 100 , and make the substrate 400 and the winding shaft 200 form an angle θ. The air pressure providing device 300 is at least partially located within the angle θ formed by the substrate 400 and the winding shaft 200 , and the air pressure providing device 300 can apply air pressure toward the angle θ to cha...

Embodiment 1

[0034] This embodiment uses figure 1 The substrate conveying system shown is used to convey the substrate 400, wherein the material of the substrate 400 is polyethylene terephthalate (PET), and the width of the substrate 400 is 650 mm, and the length is 3000 meters , the thickness of the substrate is 50 micrometers, and the roughness value of the surface 401 of the substrate 400 is 4 nanometers. When the winding tension of the base material 400 is set to 10 kilograms, the wind pressure provided by the wind pressure providing device 300 is set to 4.5 kilograms, and the winding speed is set to 15 meters per minute, the winding shaft 200 The base material 400 can be smoothly rolled up, and the base material 400 on the winding shaft 200 will not be wrinkled.

Embodiment 2

[0036] This embodiment uses figure 1 The substrate conveying system shown is used to convey the substrate 400. The difference between this embodiment and Embodiment 1 is that the wind pressure provided by the wind pressure providing device 300 is relatively weak. Specifically, the material of the base material 400 is polyethylene terephthalate (PET), and the width of the base material 400 is 650 millimeters, the length is 3000 meters, and the thickness is 50 microns, and the surface of the base material 400 401 has a roughness value of 4 nm. When the winding tension of the base material 400 is set to be 10 kilograms in weight, the air pressure provided by the wind pressure providing device 300 is set to be 4.1 kilograms in weight, and the winding speed is set to 15 meters per minute, the winding shaft 200 The base material 400 can be smoothly rolled up, and the base material 400 on the winding shaft 200 will not be wrinkled.

Abstract

The invention relates to a base material transmission system. The base material transmission system comprises a base material transferring device, a rolling rotating shaft and a wind pressure providing device. The base material transferring device is used for transferring a base material. The rolling rotating shaft is used for rolling the base material coming from the base material transferring device, and an included angle is formed between the base material and the rolling rotating shaft. As at least a part of the wind pressure providing device is located within the included angle formed between the base material and the rolling rotating shaft, wind pressure is applied in the manner of facing the included angle, and the degree of the included angle is changed, the base material located at the included angle can be supported to be flat, and folds can be prevented from generating.

Description

technical field [0001] The invention relates to a conveying technology of a substrate, and in particular to a conveying system of a flexible substrate with a rough surface. Background technique [0002] Currently, the transfer method of the flexible substrate is usually realized by using continuous roll-to-roll technology. Further, one end of the flexible substrate can be wound on the unwinding roller, and the other end of the flexible substrate can be wound on the take-up roller. The unwinding roller and the winding roller can rotate simultaneously, so that the flexible substrate is transferred from the unwinding roller to the winding roller. [0003] At present, many flexible substrates are long-meter substrates (for example, more than 1000 meters). The meter-number substrate can be maintained in a flattened state rather than sagging, so that the long-meter substrate can be smoothly transferred to the winding roller. However, when the meter-long substrate is maintained ...
