Problems solved by technology

[0005] Although the above scheme can realize the attachment of the back film 5 and the flexible substrate 4, since the back film 5 is passively pulled under the pressing force of the roller 3, the downward force on the back film 5 will affect the attachment accuracy. very big
If the downward pressure o...

Embodiment 1

[0022] A back film attachment device for a flexible substrate, comprising a workbench 10 for fixing a substrate A, a strip-shaped film 30 is arranged above the workbench 10, and the lower surface of the strip-shaped film 30 is used to absorb the film B to be pasted , the upper surface of the band-shaped film 30 is provided with a pressure roller 40, when the pressure roller 40 moves downward, the band-shaped film 30 is inclined downward to drive the end of the film B to be pasted near the pressure roller 40 to be bonded to the corresponding end of the substrate A; When the roller 40 rolls on the upper surface of the strip film 30 in the horizontal direction, the lower surface of the film B to be pasted is attached to the upper surface of the substrate A. The core of the present invention is that the pressure roller 40 is arranged on the upper surface of the strip film 30, and the lower surface of the film B to be pasted is bonded to the upper surface of the substrate A by the r...

Embodiment 2

[0027] A method for attaching a back film of a flexible substrate, comprising the following steps:

[0028] Step 100: Fix the substrate A on the upper surface of the workbench 10, and adsorb the film B to be pasted on the lower surface of the strip film 30;

[0029] Step 200: moving the workbench 10 so that the substrate A is located under the film B to be pasted as a whole;

[0030] Step 300: Drive the pressure roller 40 to move downward, so that the end of the film B to be pasted near the pressure roller 40 is aligned with the corresponding end of the substrate A;

[0031] Step 400: Drive the pressure roller 40 to roll along the upper surface of the film B to be pasted to the other end of the film B to be pasted, so that the bottom surface of the film B to be pasted and the top surface of the substrate A are completely attached.

[0032] During specific implementation, first substrate A and film B to be pasted are respectively fixed on the workbench 10 and the strip film 30...

Abstract

The invention discloses a back membrane attachment device for flexible substrates. The device comprises a workbench, above which a band-shaped membrane is arranged. The upper surface of the band-shaped membrane is provided with a pressure roller. When the pressure roller moves downward, the band-shaped membrane slopes down to drive one end of a membrane to be attached, close to the pressure roller, to fit a corresponding end of the substrate. When the pressure roller rolls on the upper surface of the band-shaped membrane in the horizontal direction, the lower surface of the membrane to be attached fits the upper surface of the substrate. A back membrane attachment method for flexible substrates comprises the following steps: respectively fixing the substrate and the membrane to be attachedon the workbench and the band-shaped membrane; moving the workbench to make the whole body of the substrate to be located below the membrane to be attached; driving the pressure roller to move downward until the membrane to be attached fit the end portion of the substrate; driving the pressure roller to roll until the lower surface of the membrane to be attached fits the upper surface of the substrate. According to the above scheme, the membrane to be attached fits the substrate through roll-in movement of the pressure roller, displacement of the membrane to be attached and the substrate willnot take place in the horizontal direction, no bubble will be generated during the attachment process, and the attachment precision is high.

Description

technical field [0001] The invention relates to the technical field of display panel production, in particular to a device and method for attaching a back film of a flexible substrate. Background technique [0002] With the development of display technology, more and more electronic devices begin to use flexible substrates that are thin and light and have good impact resistance. In the production process of flexible substrates, substrates need to be bonded with various film materials (back films), such as bonding with polarizers to change the light chromaticity of the substrates, bonding with protective films to protect the substrates from being scratched, Bond with OCA optical glue to achieve the purpose of finally bonding with the 3D glass cover. [0003] In the prior art, the attachment of the back film generally adopts the method of roller lamination, such as figure 1 As shown, the attaching device includes a lower workbench 1, an upper workbench 2 and a rolling mechan...
