And when some waste materials or bad materials with no test results appear, the material taking assembly 22 can automatically place the waste materials on the waste material tray 28, the waste materials can be recycled, the material modules are further screened, and the rate of finished products is improved.

Moreover, the automatic material conveying device B can configure the number of the feeding, discharging and conveying units 21 according to requirements; if only qualified material modules are tested and screened, only two groups of feeding and discharging conveying units 21 can be arranged, wherein the material taking and discharging station 8 on one group of the feeding and discharging conveying units 21 is responsible for feeding, the sorting manipulator C sucks the material modules on the material taking and discharging station 8 to the test seat 20 for testing, and then the material modules passing the test are placed on the material taking and discharging station 8 of the other group of the feeding and discharging conveying units 21; if the material modules need to be tested and graded, the automatic material conveying device B needs to be provided with at least three groups of feeding and discharging conveying units 21; the number of the devices is not limited according to specific requirements, and the use is more humanized.

In conclusion, the testing and sorting machine can automatically test and sort the material modules, so that the work is only ordered, and the efficiency is effectively improved; the operator only needs to be responsible for stacking and placing the material trays 1 on the feeding station 3 in batches and recovering the material trays stacked at the recovery station 5; the testing and classification of the material module are automated operation, so that labor force is released, unmanned management can be realized, and the productivity is improved.
