Description

Hinge torque test device with dummy {HINGE TORQUE TEST DEVICE WITH DUMMY}

The present invention relates to a hinge torque inspection device including a dummy.

Display technology has developed rapidly, and recently, displays with deformable display screens have been released. Displays that can be bent or rolled are collectively called 'flexible displays', and these flexible displays are classified into bendable, rollable, foldable and stretchable depending on their shape. It can be divided into stretchable, etc.

Among these, foldable smartphones have recently been commercialized, with displays that can be folded and unfolded, as they have the characteristic of not breaking even when folded. The foldable smartphone is equipped with a hinge structure inside the terminal and a foldable display, allowing the user to open and close the terminal. The hinge structure applied to these foldable smartphones can be damaged due to shock and fatigue due to frequent use. Therefore, it is necessary to test the opening and closing durability of the hinge structure in advance to predict the lifespan of the hinge structure and analyze the cause of failure. Additionally, it is necessary to measure the rotational force of the hinge in the process of folding and unfolding the foldable smartphone, and measure the force applied to the hinge at each rotation angle.

As a prior art for measuring the torque of the hinge, there is a hinge torque inspection device, Republic of Korea Patent No. 10-2333530 (registered on November 26, 2021) previously applied by the applicant of the present invention. This prior art is formed as a device for testing the hinge rotation force by mounting a foldable smartphone, etc., which includes a hinge in the form of folding and unfolding. In addition, the configuration of the sensor unit prevents foreign substances and bodies from being caught.

However, since this type of hinge torque testing device measures the rotational force by mounting the smartphone itself, the rotational force is affected by factors other than the hinge, making it difficult to accurately measure only the rotational force of the hinge. For example, the rotational force of the hinge is affected by the flexibility of the display and the effects of assembly, making it difficult to accurately measure the rotational force of the hinge. In other words, there is a demand for a hinge torque inspection device with improved accuracy so that only the torque of the hinge can be accurately measured.

Thereafter, as shown in (b) of FIG. 8, the rotating part 150 is operated to rotate the second dummy 132 in the direction facing the first dummy 131, the hinge specimen H is folded, and the load cell ( 142), the rotational force is measured. At this time, the rotating part 150 is rotated based on the rotating axis 153, and the first rotating member 154 and the second rotating member 155 are rotated along the rotating rail 156, and the rotating angle can be adjusted. You can. Afterwards, the rotating part 150 is rotated again in the opposite direction and the second dummy 132 is restored to the state shown in (a) of FIG. 8.

This operation can be repeated to measure the rotational force of the hinge specimen (H). If you want to measure the rotational force of another hinge specimen (H) of the same standard, replace the dummy part 130 with another hinge specimen (H). It can be installed to perform a torque test. For example, when it is desired to measure the rotational force of a hinge specimen (H) of a different standard, the rotational force of the hinge specimen (H) can be measured after replacing the dummy part 130 by changing it to a different standard.

As described above, the inspection device 100 according to embodiments of the present invention performs inspection after mounting the hinge specimen (H) on the dummy portion 130, thereby reducing external influences and performing a rotational force inspection with improved accuracy. It has features that allow you to get results. Conventionally, the rotational force was tested using a product equipped with a hinge specimen (H), so the rotational force measurement results may be affected by factors other than the hinge specimen (H).

On the other hand, in the inspection device 100 of the present invention, the hinge specimen (H) of the same standard is mounted on the same dummy part 130 to perform a rotational force test, so external influences can be reduced and the accuracy of the rotational force test can be improved. there is. In detail, the inspection device 100 of the present invention has the effect of greatly improving the reliability of the inspection because the rotational force inspection is performed with all configurations other than the hinge specimen (H) being the same.

In addition, the inspection device 100 according to embodiments of the present invention is characterized by easy installation and inspection. In the testing device 100 of the present invention, a rotational force test can be performed with the dummy part 130 fixed through the clamping part 120 and the dummy hanging part 140. At this time, since the clamping part 120 and the dummy hanger part 140 are fixed by pressing both sides of the dummy part 130, even if it is desired to replace the dummy part 130, the inspection can be easily performed by replacing the dummy part 130. You can proceed.

In addition, the inspection device 100 according to embodiments of the present invention allows components that do not need to be exposed to the outside to be placed inside the manipulation unit 112 so as not to interfere with the inspection during the rotational force inspection. In detail, components that do not need to be exposed to the outside, such as air hoses, wires, and motors connected to the inspection device 100, are connected to the inside of the operation unit 112 through the internal inlet 111a disposed on the base panel 111. can be placed in

In this way, the inspection device 100 according to embodiments of the present invention prevents unnecessary components from being exposed to the outside, so that the inspection does not interfere with the operation of the inspection device 100 and allows inspection to proceed in a neatly organized environment. .

Although the embodiments of the present invention have been described above, those skilled in the art will understand that addition, change, deletion or addition of components is possible without departing from the technical spirit of the present invention as set forth in the patent claims. The present invention may be modified or changed in various ways, and this will also be included in the scope of rights of the present invention.
