Synchronous clamping assembly test stand for two-sided ultraviolet ageing test

Abstract

The invention discloses a synchronous clamping assembly test stand for a two-sided ultraviolet ageing test. The synchronous clamping assembly test stand comprises a framework, guide wheels, assembly pulleys, an upper bayonet rod, a screw rod and a nut, wherein the guide wheels are arranged at the bottom of the framework, the assembly pulleys are arranged on a lower border of the framework, and the centers of all the assembly pulleys are located on the same straight line; and the upper edges of two assemblies are synchronously tightened, clamped and limited by the upper bayonet rod, the screw rod and the nut. Because two sides of the framework are both provided with structures for installing battery assemblies, the arrangement of the assembly pulleys is convenient for the regulation of the battery assemblies, and the upper clamping plate can be used for favorably limiting the battery assemblies at the two sides of the framework so as to put an end to the phenomenon of overturn of the battery assemblies; and the synchronous clamping assembly test stand is not only convenient for the moving in / out of the battery assemblies, but also high in ultraviolet radiation testing efficiency.

Description

Technical field [0001] The invention relates to an ultraviolet aging test device for solar cell components, and particularly relates to a component test rack therein. Background technique [0002] Solar cell modules are placed outdoors for a long time, so that the cells absorb sunlight and convert light energy into electrical energy to be sent to the grid. However, the ultraviolet rays in the sunlight will age the packaging materials of the modules, thereby reducing the service life of the modules. In order to simulate the real situation to test the performance of the packaging materials of solar cell modules, according to the International Electrotechnical Commission (IEC) standard, solar cell modules are Ultraviolet (UV) radiation pretreatment must be carried out before the thermal cycle / humid freeze cycle test to determine the UV attenuation of the related materials and adhesive connections. For this reason, people designed an ultraviolet aging test box. The ultraviolet aging...
