Description

Technical Field

[0001] The present invention relates to the technical field of diffusion film production, and particularly to a production process of a diffusion film with an edge-fitted light-shielding single-sided tape. Background Art

[0002] The diffusion film mainly refers to the backlight light source part of the LCD module. In order to prevent light loss, light-shielding single-sided tapes are usually attached to the upper and lower sides of the diffusion film. The existing production process is to directly attach the light-shielding single-sided tape to the two side edges of the diffusion film through a laminator. In order to ensure the parallelism between the inner side edge of the light-shielding single-sided tape and the outer side edge of the diffusion film, that is, to prevent the width of the light-shielding single-sided tape attached to the diffusion film from being different, which affects the use effect of the diffusion film, it is necessary to first cut the light-shielding single-sided tape with the cutting knife of a die cutter. When cutting the light-shielding single-sided tape, the cutting knife cuts from the upper surface of the light-shielding single-sided tape to the lower surface. Since the light-shielding single-sided tape is closely attached to the diffusion film, the diffusion film is easily scratched during the cutting process. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art solutions, the present invention provides a production process of a diffusion film with an edge-fitted light-shielding single-sided tape.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a production process of a diffusion film with an edge-fitted light-shielding single-sided tape, including the following steps:

[0005] Step S1, lamination, attaching the light-shielding single-sided tape to the surface of the diffusion film, and the light-shielding single-sided tape is attached to the two side edges of the diffusion film;

[0006] Step S2, marking, a marking mechanism makes marks on the outer surfaces of the diffusion film and the light-shielding single-sided tape to form multiple marking lines, and the distance between two adjacent marking lines is the length of the diffusion film product;

[0007] Step S3, pressing, a pressing mechanism presses the light-shielding single-sided tape onto the surface of the diffusion film to make the connection between the light-shielding single-sided tape and the diffusion film more fitting;

[0008] Step S4, side cutting, a cutting device removes the excess light-shielding single-sided tape and diffusion film on the side along the marking line;

[0009] Step S5, fixed-length cutting, after the marking recognition detection device recognizes the mark, the cutting device cuts the diffusion film and the light-shielding single-sided tape into the size required for production.

[0010] Preferably, in step S2, the marking mechanism makes marks along the length direction of the light-shielding single-sided tape, that is, the outer edge of the light-shielding single-sided tape has marking lines parallel to it.

[0011] Preferably, in step S3, the pressing mechanism and the cutting device operate simultaneously, and the cutting device is arranged at the rear side of the pressing mechanism. When the pressing mechanism presses the light-shielding single-sided tape and the diffusion film, the cutting device cuts the light-shielding single-sided tape and the diffusion film, thereby avoiding the phenomenon of flanging of the diffusion film and the light-shielding single-sided tape.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The cutting device removes the redundant light-shielding single-sided tape and diffusion film on the side along the marked line. At the same time, after the mark recognition detection device recognizes the mark, the cutting device cuts the diffusion film and the light-shielding single-sided tape into the size required for production. When the pressing mechanism presses the light-shielding single-sided tape and the diffusion film, the cutting device cuts the light-shielding single-sided tape and the diffusion film, thereby avoiding the phenomenon of flanging of the diffusion film and the light-shielding single-sided tape. Description of the Drawings

[0014] Figure 1 is a flowchart of the present invention; Detailed Embodiment

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] As Figure 1 shown, the present invention provides a production process for a diffusion film with an edge-bonded light-shielding single-sided tape, including the following steps:

[0017] Step S1, bonding, bonding the light-shielding single-sided tape on the surface of the diffusion film, and the light-shielding single-sided tape is bonded on both side edges of the diffusion film;

[0018] Step S2, marking, the marking mechanism makes marks on the outer surfaces of the diffusion film and the light-shielding single-sided tape to form multiple marked lines, and the distance between two adjacent marked lines is the length of the diffusion film product;

[0019] Step S3, pressing, the pressing mechanism presses the light-shielding single-sided tape on the surface of the diffusion film to make the connection between the light-shielding single-sided tape and the diffusion film more fitting;

[0020] Step S4, side cutting, the cutting device removes the redundant light-shielding single-sided tape and diffusion film on the side along the marked line;

[0021] Fixed-length cutting, after the mark recognition detection device recognizes the mark, the cutting device cuts the diffusion film and the light-shielding single-sided tape into the size required for production.

[0022] The marking mechanism makes marks along the length direction of the light-shielding single-sided tape, that is, the outer edge of the light-shielding single-sided tape has identification lines parallel to it.

[0023] The lamination mechanism and the cutting device operate simultaneously, and the cutting device is arranged at the rear side of the lamination mechanism. When the lamination mechanism laminates the light-shielding single-sided tape and the diffusion film, the cutting device cuts the light-shielding single-sided tape and the diffusion film, thereby preventing the diffusion film and the light-shielding single-sided tape from turning up.

[0024] The cutting device removes the redundant light-shielding single-sided tape and diffusion film on the side along the marking line. At the same time, after the marking recognition detection device recognizes the mark, the cutting device cuts the diffusion film and the light-shielding single-sided tape into the size required for production. When the lamination mechanism laminates the light-shielding single-sided tape and the diffusion film, the cutting device cuts the light-shielding single-sided tape and the diffusion film, thereby preventing the diffusion film and the light-shielding single-sided tape from turning up.
