The raw materials (back plate and section bar) of the photovoltaic module need to be subjected to a shakeout experiment to test the wear resistance of the surface coating under standard conditions, and the wear resistance of the coating on the test plate is expressed by the wear loss per unit film thickness. The test method meets the American industrial standard ASTM D968-83 and GB/T23988-.

In the conventional shakeout wear-resistance testing device, test sand is dropped onto a coated test plate from a specified height through a guide pipe until a ground material of the test plate is exposed, and the wear resistance of a coating on the test plate is expressed by the wear loss per unit film thickness of the wear. The prior device has the following defects:

The automatic shakeout abrasion tester on the market can only automatically operate 2L experimental sand once, cannot set cycle times, cannot automatically cyclically operate 120L total amount experimental sand, and still needs personnel to track on line.

Secondly, the existing test instrument is used for filling the experimental sand to the depth 2/3 of the abrasive container, an air compressor is started to blow the experimental sand to the funnel through an air pipe, the dosage of the experimental sand is not accurate and is 2/3 and 1/3 of the display container, more uncertain influence factors exist, the experimental process cannot be completely separated from personnel, and only the feeding part realizes automation.

Thirdly, the automatic shakeout abrasion tester on the market adopts an air bag to control experiment sand to be sucked into a funnel and directly falls. The flow speed of the experimental sand passing through the guide pipe cannot be controlled and fixed in a standard range, and the experimental effect cannot meet the standard requirement.
