Soft thin film transferring device and soft thin film transferring method

Abstract

The invention discloses a soft thin film transferring device and a soft thin film transferring method. The soft thin film transferring device comprises a first roller wheel, a connecting component and a second roller wheel, wherein the connecting component is pivoted to the second roller wheel and is connected to the first roller wheel telescopically so that the second roller wheel can protrude out from a first peripheral surface; and the peripheral surfaces of the first roller wheel and the second roller wheel are respectively provided with a controllable adsorption device. When in use, the soft thin film transferring method comprises the following steps of: peeling the edge part of a soft thin film which is adhered to a first support plate from the first support plate by using the second roller wheel; peeling the main part of the soft thin film from the first support plate by using the first roller wheel; adhering the edge part to a second support plate by using the second roller wheel; and adhering the main part to the second support plate by using the first roller wheel. Therefore, the device and method solve the problem of warpage when the soft thin film is transferred in the prior art.

Description

technical field [0001] The present invention relates to a flexible film transfer device and method, in particular to a flexible film transfer device and method using rollers to absorb the flexible film. Background technique [0002] At present, in many film attaching processes, due to the thin film thickness and poor rigidity, it is impossible to directly use the existing sheet attaching methods, such as the attaching method of polarizing plates, so the tool for tearing the film is usually used first. The film formed on a carrier is torn off from the carrier, and then moved to another carrier for attachment. However, when the film is peeled off and suspended, the film is prone to curling or warping, which is unfavorable for subsequent attaching operations. Also, if the film is peeled off by pulling, the peeled film will introduce residual stress, which will make the phenomenon of curling or warping more serious. If the value and distribution of the residual stress are too ...

Problems solved by technology

Further, the film 24 can not be too soft, for example: because of insufficient film thickness or its own material, the film presents soft characteristics, so that the edge part of the film 24, that is, the initial part, is bent as soon as it leaves the peeling roller 14, or due to The pulling force or tension generated by the conveying is broken and damaged, so that it cannot be correctly adsorbed by the attachment roller 12 as expected; in other words, the transfer mechanism proposed by the film transfer device 1 cannot be effectively applied to the transfer process of softer films Among them, such as: protective film, adhesive film, release film or other types of plastic soft film, etc.
