Full-automatic universal material testing system

Abstract

The full-automatic universal material testing system comprises a universal material testing machine, a sample piece material box, a waste sample collecting device, a grabbing mechanism, a size measuring device and a control module, the universal material testing machine is used for testing stretching, tearing, bending, compression and the like of a measured sample piece; the sample piece box is used for storing a to-be-tested sample piece; the waste sample collecting device is used for storing waste samples; the grabbing mechanism is used for grabbing the standard sample piece from the starting position and transferring the standard sample piece to the ending position for releasing; the size measuring device is used for measuring the size of a sample piece so as to judge whether the sample piece is a qualified sample piece, and the control module is used for coordinating the work of the universal material testing machine, the grabbing mechanism and the size measuring device. According to the full-automatic universal material testing system, automatic grabbing, feeding, testing and discarding of batch samples are achieved, manual interference is not needed, 24-hour operation can be achieved, the repeated testing consistency precision is high, the working efficiency is high, the sample storage number can be expanded, and the full-automatic universal material testing system is particularly suitable for testing of the batch samples.

Description

technical field [0001] The invention relates to the field of laboratory automation, in particular to a fully automatic universal material testing system. Background technique [0002] The universal material testing machine is a kind of material performance measurement and testing equipment commonly used in the laboratory. Generally, the material is pre-cut into a standard shape and size, and then the universal material testing machine is used for tensile, tearing, bending, compression and other tests. The physical properties of the material are obtained from the test results. [0003] At present, most universal testing machines are operated manually, and the manual testing machines have the following problems: [0004] ① Potential equipment pinch risk, fatigue damage caused by repetitive labor, etc.; [0005] ②Human factors will affect the accuracy and repeatability of test results; [0006] ③ The proportion of non-value-added time for operators is large; [0007] ④ high...

AI Technical Summary

Problems solved by technology

[0004] ① Potential equipment pinch risk, fatigue damage caused by repetitive labor, etc.;

[0005] ②Human factors will affect the accuracy and repeatability of test results;

[0006] ③ The proportion of non-value-added time for operators is large;

[0007] ④ high training costs;

[0008] ⑤ Low test efficiency;

[0009] For example, when doing a rubber tensile test, it takes about 20 seconds for the operator to manually measure the size and enter it into the system, about 10 seconds for the operator to load the sample, and about 70 seconds for the universal material testing machine to complete the relevant measurement and record the data. It takes about 10 seconds for the operator to unload the sample and discard it; it can be seen from this process that when operating the universal testing machine manually, the operator spends 63.6% of the time in a waiting state, the entire testing process is inefficient, and manual loading It is difficult to ensure the consistency of the loading position when testing the sample. Manually measure and input the size of the sample, and there are also errors and errors in the measurement situation
