FIGS. 4 and 5 are drawings for explaining the alignment process of a display panel and an FPCB by an FPCB bending and attachment device according to the present invention. Specific details for implementing the invention

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. However, in describing the present invention, descriptions of already known functions or configurations will be omitted in order to clarify the gist of the present invention.

[0022] Referring to FIGS. 1 to 3, the FPCB bending and attachment device according to the present invention includes a rotating unit (100) and an FPCB bending and attachment unit (200).

[0023] The rotating unit (100) is rotatably installed in the FPCB bending and attachment device. A plurality of display panel fixing parts (110) are formed on the upper perimeter surface of the rotating unit (100) to fix the display panel (10) by vacuum force and electrostatic force.

[0024] To this end, the rotating unit (100) has a plurality of vacuum holes (112) formed on the surface of the display panel fixing part (110) to fix the display panel (10) by vacuum force. That is, after the display panel (10) is seated on the display panel fixing part (110), it is fixed by vacuum adsorption through the vacuum force provided through the vacuum holes (112).

[0025] The rotating unit (100) has an electrostatic force generating unit (120) installed inside the display panel fixing part (110) to fix the display panel (10) by electrostatic force.

[0026] To this end, the electrostatic force generating unit (120) includes an electrode (122) and a high voltage generator (124).

[0027] The electrode (122) is installed inside the display panel fixing part (110). That is, the electrode (122) is installed so as to be arranged in a zigzag shape between the vacuum holes (112) of the display panel fixing part (110).

[0028] A high-voltage generator (124) is installed outside the rotating unit (100) and connected to an electrode (122). This high-voltage generator (124) applies a high voltage to the electrode (122). At this time, the high voltage may be direct current or alternating current.

[0029] The electrostatic force generating unit (120) configured in this manner applies a high voltage generated from a high voltage generator (124) to the electrode (122), and the electrode (122) generates an electrostatic force by the high voltage of the high voltage generator (124). Through this electrostatic force, the display panel that is seated on the display panel fixing unit (110) is fixed.

[0030] Accordingly, the rotating unit (100) can firmly fix the display panel (10) mounted on the display panel fixing part (110) by vacuum adsorption through the vacuum hole (112) and electrostatic force through the electrostatic force generating part (120).

[0031] The display panel fixing part (110) has an insulating plate (130) of a flat structure formed of a ceramic material installed below the electrode (122), and a through hole (132) corresponding to the vacuum hole (112) of the display panel fixing part (110) is formed in the insulating plate (130). The through hole (132) is intended to allow the flow of air entering through the vacuum hole (112).

[0032] In addition, the display panel fixing part (110) is equipped with a U-shaped insulator (134) formed of a ceramic material so as to form an electrostatic force boundary surface around the display panel (10).

[0033] The insulating plate (130) and the insulator (134) induce the electrostatic force of the electrostatic force generating part (120) to act intensively on the display panel (10). Therefore, after the display panel (10) is seated in the correct position of the display panel fixing part (110), micro-flow or random flow can be prevented.

[0034] The FPCB bending and attachment unit (200) is installed on one side of the rotating unit (100) to move forward and backward and rotate in the direction of the display panel fixing part (110). That is, the FPCB bending and attachment unit (200) moves forward and backward and rotates in the direction of the display panel fixing part (110) according to the control of the control unit on the FPCB bending and attachment device so as to be able to attach the FPCB (20) to the display panel (10) fixed to the display panel fixing part (110) of the rotating unit (100).

[0035] The FPCB bending and attachment unit (200) has an FPCB fixing part (210) formed on its upper surface to fix the FPCB (20) by vacuum force and align it with the display panel (10). To this end, the FPCB bending and attachment unit (200) has a plurality of vacuum holes (212) formed in the FPCB fixing part (210) to fix the FPCB (20) by vacuum force. That is, the FPCB (20) can be vacuum-adsorbed to the FPCB fixing part by the vacuum force provided through the vacuum holes (212) and firmly fixed.

[0036] Hereinafter, the process of aligning a display panel and an FPCB by the FPCB bending and attachment device according to the present invention will be described.

[0037] First, the display panel (10) is fixed to the display panel fixing part (110) of the rotating unit (100) by vacuum force and electrostatic force, and the FPCB (20) protruding outward from the display panel is fixed to the FPCB fixing part (210) of the FPCB bending and attachment unit (200) by vacuum force.

[0038] After the display panel (10) is seated in the correct position of the display panel fixing part (110), it is vacuum-adsorbed and fixed to the display panel fixing part (110) by the vacuum force provided through the vacuum hole (112), and additionally, is firmly fixed to the display panel fixing part (110) by the electrostatic force provided from the electrostatic force generating part (120). That is, the display panel (10) can be firmly fixed by a double adsorption structure using vacuum force and electrostatic force while seated on the display panel fixing part (110).

[0039] After the above FPCB (20) is seated in the correct position of the FPCB fixing part (210), it can be vacuum-adsorbed to the FPCB fixing part (210) by the vacuum force provided through the vacuum hole (212) and firmly fixed.

[0040] In the display panel fixing part (110), an insulating plate (130) is installed below the electrode (122), and at the same time, a U-shaped insulator (134) is installed to form an electrostatic force boundary surface around the periphery of the display panel (10). That is, the insulating plate (130) guides the electrostatic force of the electrostatic force generating part (120) toward the display panel (10), and the insulator (134) prevents the dispersion of the electrostatic force in the periphery direction of the display panel (10) on the display panel fixing part (110).

[0041] Accordingly, the insulating plate (130) and the insulator (134) can induce the electrostatic force to act intensively on the display panel (10), thereby preventing micro-movement or random movement of the display panel (10) when aligning the FPCB (20) while the display panel (10) is seated in the correct position of the display panel fixing part (110), thereby increasing the stability and accuracy of the alignment.

[0042] Referring to FIG. 4, the display panel (10) is fixed to the display panel fixing part (110) of the rotating unit (100) through vacuum force and electrostatic force, and the FPCB (20) is fixed to the FPCB fixing part (210) of the FPCB bending and attachment unit (200) through vacuum force so as to correspond to the display panel (10).

[0043] Referring to FIG. 5, the FPCB bending and attachment unit (200) is rotated 180 degrees toward the display panel fixing part (110) to bend and attach the FPCB (20) protruding outwardly from the display panel (10) to the display panel (10). At this time, the display panel (10) and the FPCB (20) can be attached to each other due to an adhesive component.

[0044] Through the above-described series of processes, a plurality of display panels (10) rotate a rotating unit (100) fixed to a display panel fixing part (110) through vacuum force and electrostatic force, and an FPCB (20) moves forward and backward and rotates an FPCB bending and attachment unit (200) fixed through vacuum force in the direction of the rotating unit (100), thereby rotating and bending the FPCB (20) to the display panel and aligning it.

[0045] As described above, the FPCB bending and attachment device according to the present invention can prevent micro-flow or arbitrary flow by firmly fixing the display panel (10) by vacuum force and electrostatic force when aligning the FPCB (20) to the display panel (10), thereby increasing the stability and accuracy of the alignment, preventing the error rate of the product, and improving quality.

[0046] Although specific embodiments of the present invention have been described and illustrated above, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should not be understood individually from the technical spirit or perspective of the present invention, and the modified embodiments should be considered to fall within the scope of the claims of the present invention.
