The touch screen industry has been maintained for a long time in specialized fields such as ATM, kiosk, POS, etc., but expanded to relatively general products such as navigation and PDA in the 2000s. Has been widened.

Today, due to the convenience of touch screens, the demand for touch screens has rapidly increased, and in accordance with these demands, the size of substrates of touch screens has also become increasingly large and slim, from small to medium and large.

However, as the size of the substrate becomes larger and slimmer, lamination is not performed properly in the process of laminating a laminate such as ITO film or OCA (Optically Clear Adhesive) on the substrate, resulting in an increase in the defective rate of the product. have.

As a related art, a vacuum laminating apparatus of Korean Patent No. 10-1169792 is disclosed.

When in contact with the upper side, the pump member 130 relates to a device for laminating the film on the substrate while maintaining the vacuum state as possible after suctioning the air inside the receiving portion 122.

However, since this conventional technique only responds to the tilt problem of X / Y biaxial straight line in lamination and uses jig for the problem of tilt in rotation, when the environment changes for tilt in rotation, There was a problem that must be set continuously by each operator. In addition, the larger the substrate, there is a problem that the defective rate of the product is higher because the film is not laminated to the exact position of the substrate.

The controller calculates an optimal correction value based on the transmitted tilt data, thereby controlling the first servo motor (not shown) located below the air plate 220.

The first servo motor rotates the air plate 220 by a predetermined angle according to the correction value, and as a result, the substrate 310 adsorbed to the air plate 220 may be laminated at the correct position.

The second vision camera 250 may be positioned above the film stacking unit 260, and detects and transmits the tilt data to the controller before photographing and transporting the film 320 marking of the film stacking unit 260. In charge of.

The controller calculates an optimal correction value based on the tilt data transmitted by the second vision camera 250, and thus controls the second servo motor 242 of the film transfer and loading unit 240.

The second servo motor 242 rotates the gripper 243 by a predetermined angle (θ) according to the correction value, and the gripper 243 in the rotated state lifts the film 320 of the film stack to the upper side by vacuum suction. do. The gripper 243 adsorbing the film 320 is rotated to the proper position by the second servo motor 242 and then moved to the transfer plate.

Therefore, the film transfer and stacking unit 242 may always stack the film 320 at the correct position of the substrate 310 regardless of the degree of twisting of the film 320 loaded on the film stacking unit 260.
