The feeding mechanism 31 is a feeding manipulator with four degrees of freedom, and specifically can translate along the XYZ axes and rotate around the X/Y/Z axes, and the feeding manipulator can grab materials from the tray 9 of the feeding station 21 and place the materials into the test tray at the test tray buffer position 6. The automatic balance swinging device has the advantages that the automatic balance swinging device is adopted, so that the angle and the height of materials in the test tray are consistent, the balance swinging effect with unified angle and consistent height is realized, and the effectiveness of the test is ensured.

The test tray taking mechanism 34 is an XZ two-degree-of-freedom test tray manipulator, and the test tray manipulator can grab the test tray at the preliminary test position 7 and then place the grabbed test tray in the MTF test device 4, so that the MTF test device 4 can test the material on the test tray, and the test tray which is tested in the MTF test device 4 can be grabbed, taken out of the MTF test device 4 and placed at the preliminary test position 7.

The material returning mechanism 32 is a material returning manipulator with three degrees of freedom of XYZ, and the material returning manipulator can take out the tested materials in the test tray at the test tray buffer position 6 and respectively place the tested materials in the material trays 9 of the sorting bins which are classified correspondingly according to the classification results of the tested materials. The measured materials are sorted by adopting a material returning manipulator, so that the error material mixing caused by manual sorting is avoided.

Further, when the test tray 9 is tested in the MTF testing device 4, the test tray at the test tray buffer position 6 can simultaneously perform material returning of the tested materials and material loading of the tested materials, that is, each time the material returning manipulator takes a certain amount of the tested materials away from the test tray at the test tray buffer position 6 to perform sorting and material loading in a plurality of sorting bins, the material loading manipulator will grab the same amount of the tested materials from the tray 9 at the feeding station 21 and place the materials into the cavities of the test tray, when the material loading manipulator moves from the area of the test tray buffer position 6 to the feeding station 21 to continuously take the tested materials, the material returning manipulator returns to the test tray buffer position 6 to continuously take the tested materials after placing all the materials. The feeding manipulator and the material returning manipulator realize the material returning of the tested material and the feeding of the material to be tested in the time-sharing matching and interaction process, so that the next test tray filled with the material to be tested is prepared at the 6 position of the test tray cache position.

The number of the test trays is two. The two test trays are used circularly, the disc changing action is automatically realized, the switching between the material to be tested and the tested material is quickly completed, and the disc changing time is saved to a greater extent.
