Bending robot

Abstract

Provided is a bending robot capable of uniformly bending a bending portion of a flexible printed circuit board into a circular arc shape. The bending robot includes a substrate support, a body, a first arm, a second arm, a third arm, a fourth arm, a fifth arm, a sixth arm and a control unit. The substrate support supports an object to be operated to which a first end portion of the flexible printed circuit board, having the first end portion and a second end portion opposite the first end portion, is attached. The body is arranged to be spaced from the object to be operated of the support. The first arm includes a first end portion and a second end portion opposite the first end portion, wherein the first end portion is coupled to the upper part of the body so that axial rotation can be performed therebetween. The second arm includes a first end portion and a second end portion opposite the first end portion, wherein the first end portion is coupled to the second end portion of the first arm so that hinged rotation can be performed therebetween. The third arm includes a first end portion and a second end portion opposite the first end portion, wherein the first end portion is coupled to the second end portion of the second arm so that hinged rotation can be performed therebetween. The fourth arm includes a first end portion and a second end portion opposite the first end portion, wherein the first end portion is coupled to the second end portion of the third arm so that axial rotation can be performed therebetween. The fifth arm includes a first end portion and a second end portion opposite the first end portion, wherein the first end portion is coupled to the second end portion of the fourth arm so that hinged rotation can be performed therebetween. The sixth arm includes a first end portion and a second end portion opposite the first end portion, wherein the first end portion is coupled to the second end portion of the fifth arm so that axial rotation can be performed therebetween, and includes a finger for fixing the second end portion of the flexible printed circuit board. The control unit controls the movements of the first arm to the sixth arm.

Description

Technical field [0001] The present invention relates to a bending robot, and more particularly to a flexible printed circuit board for curving a flexible printed circuit board configured to be bent at the back surface or bending flexible display substrate on the back surface of the display panel when manufacturing a smartphone. Background technique [0002] With the development of information society and the development of various portable electronic devices such as mobile communication terminals and laptops, Flat Panel Display Pan EL can be applied. [0003] In this flat panel display panel, a liquid crystal display panel (LCD) and an organic light-emitting display panel (OL ED) are widely used. The liquid crystal display panel has a liquid crystal layer that acts as a switch between the upper substrate and the lower substrate, by controlling the light passage of light generated by the backlight unit, the organic light-emitting display plate has an organic light-emitting layer b...

AI Technical Summary

Problems solved by technology

[0012] Preferably, as Figure 6 As shown, the bending part BP should be formed in a circular arc shape, but in the case of the existing bending robot, such as Figure 5 As shown in , the arc shape is not uniformly formed and breakage occurs

[0013] Also, according to the conventional bending robot, since the other end of the flexible printed circuit board is not fixed, the bending occurs at a position that does not reach or exceed the position that needs to be bent.

[0014] And, according to existing bending robot, respectively constitute the part that carries out each function, namely pressure member 3, support plate 1 etc., and respectively constitute the drive unit (not shown) that is used to drive these parts, so existing bending robot Robots take up a lot of space, and the number is limited when they are set in a limited area
