Description

Technical Field

[0001] The utility model relates to the technical field of laminating sheets and rolls, in particular to a sheet-to-roll laminating device. Background Art

[0002] Many optical films such as polarizers, phase difference films and DBEF films are provided in sheets when they leave the factory. However, these materials have poor resistance to water vapor, high temperature and scratches, and their thickness does not meet the use requirements. Therefore, a protective layer needs to be attached to the sheet to protect the sheet. Therefore, a device is needed to attach the protective layer to complete the bonding.

After corona treatment, the substrate is manually transferred to the gluing device, and the glued sheet is manually transferred to the laminating machine for sheet-to-roll lamination, which cannot achieve fully automatic substrate processing and lamination.

[0047] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0048] like Figure 1As shown, the sheet-to-roll laminating device provided in this embodiment includes a conveyor belt 100, a first detection component 200, a corona component 300, a glue coating component 400 and a winding component 500; the conveyor belt 100 is wound around two pulleys, and the two pulleys rotate in the same direction to drive the conveyor belt 100 to move, so as to Figure 1 For example, the two pulleys rotate in the clockwise direction to drive the transmission belt to rotate clockwise, so that the conveyor belt 100 supports the first substrate 10 and drives the first substrate 10 to move rightward.

[0049] It should be noted that after the first substrate 10 is placed on the conveyor belt 100 , the surface of the first substrate 10 has a first protective film 11 . Before the first substrate 10 is corona-discharged, the first protective film 11 needs to be manually torn off from the first substrate 10 .

[0050] The first detection member 200, the corona member 300 and the glue coating member 400 are sequentially arranged along the conveying direction of the conveyor belt 100. Figure 1 For example, the first detecting member 200, the corona member 300 and the glue coating member 400 are sequentially arranged from left to right.

[0051] The first detection component 200 is electrically connected to the corona component 300 and the glue coating component 400, respectively. The first detection component 200 is used to detect the position of the first substrate 10 on the conveyor belt 100, and control the operation of the corona component 300 and the glue coating component 400 accordingly according to the detection information. Specifically, when the first detection component 200 detects that there is the first substrate 10 on the conveyor belt 100, the first detection component 200 controls the corona component 300 and the glue coating component 400 to start working. As the transmission belt is transported, the first substrate 10 on the conveyor belt 100 is sequentially subjected to corona and glue coating.

[0052] In addition, in an optional embodiment, the sheet-to-roll laminating device also includes an oven 600; the gluing component 400 and the oven 600 are arranged in sequence along the conveying direction of the conveyor belt 100, and the oven 600 is used to dry the first substrate 10 after gluing, so that the first substrate 10 is corona-glued in sequence, and then the first substrate 10 is dried and cured by using the oven 600.

[0053] The winding member 500 is disposed at the end of the conveyor belt 100 , and the winding member 500 is used to attach the second substrate 20 to the first substrate 10 to form a sheet to be cut.

[0054] Specifically, the winding component 500 includes a unwinding roller 510 and a bonding roller 520; the second substrate 20 is wound on the unwinding roller 510. In addition, a supporting roller is provided, which is arranged opposite to the bonding roller 520. The supporting roller is located at the end of the conveyor belt 100. The conveyor belt 100 transports the first substrate 10 to the supporting roller, so that the first substrate 10 is located between the supporting roller and the bonding roller 520. The bonding roller 520 guides the second substrate 20, thereby bonding the second substrate 20 to the first substrate 10 to form a sheet to be cut.

[0055] In addition, it should be noted that when the second substrate 20 is rolled up on the unwinding roller 510, the surface of the second substrate 20 has a second protective film 21. In order to tear off the second protective film 21, a tearing roller 530 and a tearing film winding roller 540 are also provided. The second protective film 21 is manually torn off and rolled up in the tearing film winding roller 540. The tearing film roller 530 serves to guide the second protective film 21 and drive the second substrate 20 to move. When the unwinding roller 510 is unwound, the second substrate 20 is unwound, and at the same time, the second protective film 21 is torn off from the second substrate 20 and rolled up on the tearing film winding roller 540.

[0056] The sheet-to-roll laminating device provided in the present embodiment places the first substrate 10 on a transmission belt and uses the transmission belt to drive the first substrate 10 to move. Since the first detection component 200, the corona component 300 and the glue coating component 400 are arranged in sequence along the conveying direction of the transmission belt, when the first detection component 200 detects the first substrate 10 on the transmission belt, the corona component 300 and the glue coating component 400 start to work and perform the corona process and the glue coating process on the first substrate 10. After the corona and glue coating are completed, the winding component 500 bonds the second substrate 20 to the first substrate 10 to form a sheet to be cut, and the sheet-to-roll laminating is completed, and the corona, glue coating and laminating work are automated, which alleviates the technical problem that the traditional laminating equipment in the prior art has a low degree of automation and cannot realize fully automatic substrate processing and laminating.

The second detection member 900 is used to detect the position of the sheet to be cut and control the operation of the cutting member 800 according to the detection information.

[0063] Specifically, the second detection component 900 includes a second detector and a second controller; the second detector can be specifically set as a laser detector or a position sensor, and the second detector can detect the sheet to be cut; the second controller can be set as a single-chip microcomputer, a microprocessor unit, or a PCL controller.

When the second detector detects the second substrate 20, the second detector sends a detection signal, and the second controller receives the detection signal and controls the cutting component 800 to start working accordingly.
