The equipment is specially used to carry out ice ball impact test on solar cells to verify the ability of battery modules to resist hail impact, the sample is placed horizontally on the test platform, the transmitter is located above the sample, the ice ball is launched from top to bottom, and the automatic aiming and positioning between different impact points is carried out by means of the fixed emission device of the sample
The equipment is composed of a sample platform, a numerical control positioning device, an ice hockey launching device, an ice hockey production and preservation device, etcThe sample platform is made of industrial forming aluminum material, the sample is horizontal on the platform, and the platform is surrounded by a plexiglass protective screen to prevent test fragmentsThe numerical control positioning device is used for the positioning of the firing point, the numerical control dual-axis drive, with the light point indication device, after positioning and setting the number of relevant data, the equipment automatically moves the muzzle to aim at the impact point, without manual operation;
The launch device uses compressed air as the power source, and the impact speed is adjusted by adjusting the compressed air pressure, and the rushing ball speed is detected by an electronic velocity measuring element installed in the launch tube
The equipment is controlled by PLC + man-machine interface, the position of the impact point, the impact speed and other values can be set manually on the man-machine interface, and the impact process can be automatically completed by PLC.
