Description

Multi-tester for flexible material

The present invention relates to a multi-tester targeting a flexible material, which has a function of bending, folding, tensile, and torsion testing of a specimen requiring a test, and at the same time, is a flexible material with excellent space utilization. It's about multi-testers.

Recently, flexible materials (polyimide, polypropylene, etc.) have been attracting attention in the field of many wearable products and displays, and the demand for bending, folding, tensile, and torsion test devices to study them is gradually increasing.

On the other hand, in the domestic market, as a device for testing the flexible material, an experimental device produced outside the country is used, and there is a tendency to rely on an overseas test device rather than a domestic test device.

In addition, in the existing test apparatus, there is already a test apparatus capable of performing each test, but it is not possible to perform various tests with one machine. There was a problem that I had to purchase each to fit.

Also, when performing different tests successively on the same sample (e.g., when performing a torsion test, performing a tensile test, or performing a torsion test after performing a bending test), test the specimen with different test equipment. had to be moved to

Due to this, the fatigue of the experimenter who tests the specimen is increased, the concentration on the experiment is decreased, and there is a problem that unnecessary time is required.

In addition, space utilization was not good because all test machines had to be installed in the limited space of the laboratory.

On the other hand, paying attention to such a problem, looking at the developed test apparatus, Korean Patent Registration No. 10-1412283 [Patent Document 1] is disclosed. However, [Patent Document 1] has a problem in that only the tensile and compression tests can be selectively tested.

In addition, as an apparatus for multi-purpose testing of a specimen, Korean Patent Application Laid-Open No. 10-2017-0106010 [Patent Document 2] is disclosed, but the size of the experimental apparatus for performing the multi-purpose test is too large or unnecessary. There is a potential problem in that a large number of devices are provided, and the purpose of being used for experiments is lost, and the price of the test device is increased.

Accordingly, bending, folding, tensile, torsion tests, etc. can be performed in one test device, but it wastes space and tests flexible materials that can be provided at a low price by having a simplified configuration. There is an urgent need to develop the technology of the test device.
