Problems solved by technology

[0002] The test of the gravimetric moisture permeability test requires precision, and testing and weighing are two important steps. In order to improve the test efficiency, the current gravimetric moisture permeability tester often sets the test and weighing in an environmental chamber, while testing While weighing, the temperature and humidity of the test environment often affect the stability of the weighing element and the test accuracy
In addition, the test steps of the gravimetric test are cumbersome, and the test time is often longer. The current gravimetric moisture permeability tester has fewer test stations, and the efficiency of one test is extremely low.

Embodiment 1

[0036] Such as Figure 1-Figure 2 As shown, the multi-chamber gravimetric moisture permeability test system includes a frame 1, a test chamber 8, a buffer chamber 6, a weighing chamber 5, and a moving device for a manipulator. The frame 1 is a framework for installing various components. A test cup 9 is provided in the test chamber 8, a weighing element 10 is provided in the weighing chamber 5, a manipulator moving device is provided on the frame 1, and a sample is provided in the test cup 9. The manipulator moving device includes an X-axis moving device 7, a Y-axis moving device 11, and a Z-axis moving device 3. The manipulator 2 is installed on the manipulator moving device. The manipulator moving device can move the test cup 9 along the XYZ axis, and the manipulator 2 can move freely in any direction. Rotating, the gripping range of the manipulator 2 covers the entire range of the test chamber 8 , the buffer chamber 6 and the weighing chamber 5 . After the test cup 9 reach...

Embodiment 2

[0044] Replace the manipulator in Example 1 with a vacuum chuck, and drive the vacuum chuck to move the test cup through the X-axis moving device, Y-axis moving device and Z-axis moving device to complete the entire experiment process. Other structures are the same as in Example 1.

Embodiment 3

[0046] Replace the specific form of the manipulator moving device in Embodiment 1 with a turntable structure, install a turntable that rotates in the horizontal direction at the middle of the bottom of the frame, the upper part of the turntable that turns in the horizontal direction is connected with the turntable that turns in the vertical direction, and the turntable that turns in the vertical direction The turntable is connected with the connecting rod, and the manipulator is installed at the end of the connecting rod; the turntable that rotates in the horizontal direction and the turntable that rotates in the vertical direction are connected with the drive device, and driven by the drive device, the turntable that rotates in the vertical direction drives the manipulator to move up and down to grab different The test cup in the test chamber, the turntable that rotates in the horizontal direction drives the manipulator to move horizontally, and moves the test cup from the test...

Abstract

The invention discloses a multiple-cavity weighting-method water-vapor permeability testing system and a testing method. The system of the invention comprises a rack which is provided with a testing cavity and a weighing cavity. A weighing element is arranged inside the weighing cavity to weigh test cups. The rack is also provided with a mobile device, on which a clamping device is arranged. The mobile device drives the clamping device to move, and the clamping device clamps the test cups to enter and go out of the testing cavity to finish the testing. By separating the testing cavity and the weighing cavity, stability of a weighing environment is guaranteed, and weighing precision of the weighing element is enhanced. By arranging a buffer cavity, the test cups in the testing cavity can be balanced to the weighing environment in advance. Thus, weighing errors are eliminated, and weighing precision is further raised. The test cups in the testing cavity are arranged in a multilevel matrix, thus greatly increasing testing efficiency. As the manipulator-carrying mobile device is arranged for transport of the test cups, operating precision of the testing system is enhanced.

Description

technical field [0001] The invention relates to a test system for detecting material barrier properties, in particular to a multi-cavity weighing method moisture permeability test system and a test method. Background technique [0002] The test of the gravimetric moisture permeability test requires precision, and testing and weighing are two important steps. In order to improve the test efficiency, the current gravimetric moisture permeability tester often sets the test and weighing in an environmental chamber, while testing While weighing, the temperature and humidity of the test environment often affect the stability of the weighing element and affect the test accuracy. In addition, the test steps of the gravimetric test are cumbersome, and the test time is often long. The current gravimetric moisture permeability tester has fewer test stations, and the efficiency of one test is extremely low. Therefore, there is an urgent need for a high-efficiency and precise weighing m...
