Description

[0001] PASSIVE TYPE FLEXIBLE SUBSTRATE INSPECTION APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a manual conversion type bending reliability inspection apparatus. More particularly, to a passive conversion type bending reliability inspection apparatus which repeatedly bends an object to be inspected such as a flexible PCB substrate and inspects the durability of the object to be inspected against the bending force.

BACKGROUND ART [0002] In recent years, with the rapid development of technologies related to various electric and electronic devices, the technology related to display parts and various connector devices is gradually being developed.

In particular, technologies relating to organic light emitting diodes and flexible connectors that are bent or bent flexibly are attracting attention, and accordingly, the roles of the devices for manufacturing or testing are also emphasized.

In the case of inspection objects such as display parts and connectors or flexible PCBs which are manufactured to allow flexible bending, the durability of the object to be inspected against repetitive bending force before shipment is measured, and a flexible inspection is performed to determine whether the product is defective .

In the case of a passive bending reliability testing apparatus for performing such inspection, the reliability of the inspection can be secured only if the bending moment, that is, the bending force, is designed to be constant at a specific portion of the object to be inspected.

For example, in the related art, when the right mounting member is rotated about the rotation axis in a state where the inspection object is arranged across the left and right fixing members, the left upper corner portion of the right fixing member is rotated about the rotation axis And a bending inspection device configured to exert a tensile force together with a bending force on the portion disposed at the upper left corner portion of the right mounting member in the inspection object disposed over the left and right mounting members as the test object rotates, Is carried out.

However, the conventional bending inspection apparatus described above has a limitation in that when the right fixing member is rotated, it is interfered by the edge portion of the left fixing member and can not be completely rotated so as to be superimposed on the left fixing member.

In addition, when inspecting the object to be inspected, the bending force applied to the object to be inspected may be irregularly applied to an unspecified part, and physical force such as tensile force or compressive force other than the bending force may be applied to the object, There is a problem that the reliability of the test is very low as a result.

In addition, in recent years, in order to increase the reliability of inspection, inspection apparatuses constructed by employing various computers or electronic equipment have been continuously appearing. However, most of them are very expensive, and it takes much time and cost for installation / disassembly and maintenance / repair There is also a problem.

FIG. 8 is a perspective view sequentially showing a second operating state of the passive bending reliability testing apparatus according to the embodiment of the present invention, and FIG. 9 is a side view showing the passive bending reliability testing apparatus of the passive bending reliability testing apparatus according to the embodiment of the present invention. 2 is a side view showing the operation states sequentially.

The first and second operating states of the passive bending reliability testing apparatus according to the embodiment of the present invention will be described with reference to FIGS. 6 to 9. First, at the time of inspecting the inspected object according to the first operating state, The object to be inspected may be positioned on the inspection plate 33 of the unit 30 and the object to be inspected may be fixed through the fixing jig 45 or may be fixed more firmly by a separate fixing means have.

When the drive unit 10 is operated through a separate control unit (not shown) for controlling the drive unit 10, the rotation shaft 11 of the drive unit 10 rotates, The first gear 211 rotates as the first gear 211 rotates and the second gear 212 engaged with the first gear 211 rotates relative to the first gear 211 as the first gear 211 rotates do.

The first folding frame 311 and the second folding frame 312 connected to the first gear 211 and the second gear 212 interlock with each other to rotate relative to each other while the first folding frame 311 and the second folding frame 311 are rotated relative to each other, Both ends of the folding frame 312 gradually move upwards and are mutually folded in the In direction.

Since the first gear 211 and the second gear 212 are connected to each other in a meshing gear fashion, folding is performed so as to have a constant torque, so that a physical force such as a tensile force or a compressive force other than the bending force is applied to the object to be inspected And as a result, the occurrence of errors in the inspection result is minimized, thereby improving the precision of the inspection.

In this process, the inspection plate 33 is folded about the hinge axis 331 according to the folding of the first folding frame 311 and the second folding frame 312, The bending reliability test for the object to be inspected fixed to the inspection plate 33 becomes possible.

At this time, in order to fold the inspection object fixed to the inspection plate 33 as much as possible, the variable clamp 40 is rotated around the folding frame 31, The position can be manually changed by the user.

For example, when the end of the connecting member 42 of the variable clamp 40 is fixed so as to face upward so that the connecting member 42 is rotatably connected to the end of the test plate 33, Can be more fully folded to the positions where both ends of the hour test plate 33 meet.

When the in-bending reliability test of the object to be inspected is performed according to the first operation state, both ends of the inspection plate 33 are arranged closer to the folding frame 31 than the folding frame 31, The positions of both ends of the test plate 33 can be varied through the variable clamp 40 to perform the bending reliability test according to the first operating condition.

When the folding frame 31 is folded, the inspection object fixed to the inspection plate 33 is flexed as much as possible, so that a smooth bending reliability inspection can be performed.

Meanwhile, when performing the outward bending reliability test according to the second operation state, the folding frame 31 is folded downward. In this case, the folding frame 31 is folded down through the variable clamp 40, The position of the both ends of the inspection plate 33 can be easily and quickly manually changed so that both ends of the inspection plate 33 are positioned lower than the folding frame 31. [

That is, when the connecting member 42 is rotatably connected to the end portion of the inspection plate 33 by being fixed so that the end of the connecting member 42 of the variable clamp 40 is downwardly directed, It can be more fully folded to the position where both ends of the inspection plate 33 meet.

Thereafter, when folding the folding frame 31 downward according to the second operation, the object to be inspected positioned on the inspection plate 33 is completely bent, resulting in folding as much as possible, And the precision can be further improved.

According to the present invention constructed as described above, it is possible to manually adjust the position of both ends of the object to be inspected so as to fix the position of the object to be inspected so as to maximally fold the object in the In or Out direction folding inspection of the object. It is possible to reduce the occurrence of errors in the inspection results to a minimum and improve the precision of the inspection so as to enable reliable inspection. In addition to the simple structure, It is an invention that can make it possible to make installation / disassembly or maintenance / repair in case of failure quickly and easily, and to reduce various expenses as much as possible.
