AI Technical Summary

Problems solved by technology

The force of manually clamping the sample is difficult to control and unify, and the improper clamping method will lead to large errors in the detection of gas barrier / permeability of the sample
Moreover, the process of manually clamping the samples is cumbersome and requires a high level of skill of the operator, so when different people clamp the samples, it is difficult to ensure the reliability of the sealing of each group of samples; When sampling, it is difficult to ensure the consistency of the packaging of different groups of samples; the above problems will lead to inaccurate and unstable test results of the instrument, and ultimately reduce the test efficiency and detection accuracy of the equipment

Embodiment 1

[0065] Hereinafter, this embodiment will be described by taking the first test chamber and the second test chamber relative to each other up and down as an example:

[0066] Such as figure 1 and figure 2 As shown, a sample automatic clamping structure of this embodiment includes:

[0067] The first test cavity 1 and the second test cavity 6; the sample 5 is arranged between the first test cavity 1 and the second test cavity 6; the first test cavity 1 and the second test cavity 6 are respectively arranged on the sample 5 above and below;

[0068] Before clamping the sample, the first driving device is used to drive the first test cavity to move upwards, and the second drive device is used to drive the second test cavity to move horizontally, so that the first test cavity and the second test cavity are separated and the second test cavity is separated. The second test chamber protrudes from the outside of the environmental chamber;

[0069] When the sample is placed in the ...

Embodiment 2

[0108] Such as Figure 4 and Figure 5 As shown, the difference from the first embodiment is that in the automatic sample clamping structure of this embodiment, the cylinder i3 is fixed on the second fixing plate 12 , and the cylinder ii9 is fixed on the first fixing plate 8 . Wherein, the first fixing plate 8 is arranged below the second testing chamber 6 , and the second fixing plate 12 is arranged above the first testing chamber 1 .

[0109] The opening and closing of the first test chamber and the second test chamber in this embodiment are driven by the driving device, the sample is well sealed, and the compression degree is consistent, and the purpose of stable test data and high detection accuracy is achieved; the test of this embodiment The sample automatic clamping structure realizes the automation of the entire clamping process and improves the efficiency of clamping the sample; the automatic sample clamping structure of this embodiment has a high degree of automation ...

Embodiment 3

[0111] A sample automatic clamping structure in this embodiment includes:

[0112] A first test chamber and a second test chamber, a sample is arranged between the first test chamber and the second test chamber; the first test chamber and the second test chamber are respectively arranged above and below the sample;

[0113] a first driving device, which is connected to the first test cavity;

[0114] a second driving device, which is connected to the second test cavity;

[0115] Before the sample is clamped, the second driving device is used to drive the second test cavity to move down a second preset distance, and the first drive device is used to drive the first test cavity to move in the horizontal direction, so that the first test cavity and the second test cavity The two test chambers are separated and the first test chamber protrudes outside the environmental chamber;

[0116] When the sample is adsorbed to the first test chamber, the first driving device is used to dr...

Abstract

The invention provides an automatic sample clamping structure and a gas permeation testing system. The automatic sample clamping structure which is arranged in a sealable environment bin comprises a first testing cavity, a second testing cavity, a first drive device and a second drive device and is characterized in that the first testing cavity and the second testing cavity are arranged on two sides of a sample, the first drive device is connected with the first testing cavity, the second drive device is connected with the second testing cavity, and the first drive device and the second drivedevice are used for driving the first testing cavity and the second testing cavity to move relative to each other to combine together or separate from each other so as to automatically compress the sample and allow the sample to automatically enter and exit the environment bin.

Description

technical field [0001] The disclosure belongs to the field of sample detection, and in particular relates to a sample automatic clamping structure and a gas permeation testing system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The principle of the pressure difference method to detect the gas barrier / permeability test of the sample is: due to the pressure difference on both sides of the sample, the gas permeates vertically from one side of the sample to the other side, according to the amount of gas permeated through the sample , to determine the barrier / permeability of the sample to gas. If the sample is not well sealed, the gas on one side will leak laterally from the periphery of the sample into the other side, resulting in inaccurate test results; when testing multiple groups of samples at the same time, when comparing the permea...
