Example Embodiment

[0035] Example 1:

[0036] Such as Figure 1-Figure 2 As shown, the multi-cavity weighing method moisture permeability test system includes a frame 1, a test cavity 8, a buffer cavity 6, a weighing cavity 5, a manipulator moving device, and the frame 1 is an installation framework for various components. The test chamber 8 is provided with a test cup 9, the weighing chamber 5 is provided with a weighing element 10, the frame 1 is provided with a robot moving device, and the test cup 9 is provided with a sample. The manipulator moving device includes X-axis moving device 7, Y-axis moving device 11, Z-axis moving device 3. The manipulator moving device is equipped with a manipulator 2. The manipulator moving device can bring the test cup 9 to move along the XYZ axis, and the manipulator 2 can move freely in any direction When rotating, the gripping range of the manipulator 2 covers the entire range of the test cavity 8, the buffer cavity 6 and the weighing cavity 5. After the tes...

Example Embodiment

[0043] Example 2:

[0044] The manipulator in Example 1 was replaced with a vacuum chuck, and the X-axis moving device, Y-axis moving device and Z-axis moving device were used to drive the vacuum chuck to move the test cup to complete the entire experimental process. The other structure is the same as in Embodiment 1.

Example Embodiment

[0045] Example 3:

[0046] The specific form of the manipulator moving device in Example 1 is replaced with a turntable structure. A horizontally rotating turntable is installed in the middle of the bottom of the frame. The upper part of the horizontally rotating turntable is connected to the vertically rotating turntable. The turntable is connected to the connecting rod, and the end of the connecting rod is equipped with a manipulator; both the horizontally rotating turntable and the vertical rotating turntable are connected to the driving device. Driven by the driving device, the vertically rotating turntable drives the manipulator to move up and down. For the test cup at the location, the horizontally rotating turntable drives the manipulator to move horizontally, moving the test cup from the test chamber to the weighing chamber.

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...
