10. according to claim 9 be used for solar panels thermal cycle test method, which is characterized in that the step 2): institute
Stating clamp assemblies, specific step is as follows to the positive clamping of solar panels to be tested progress:
2.1) both ends of solar panels to be tested are respectively placed on the second limiting section of clamping terminal；
2.2) direction that clamp drive mechanism drives clamping limb to close solar panels to be tested is mobile, until by the sun to be tested
Energy edges of boards edge is caught in the first limiting slot of the first limiting section of clamping terminal, and the clamping plate in the first limiting slot clamps it；
The step 8): the clamp assemblies carry out reverse side clamping to solar panels to be tested, and specific step is as follows:
8.1) it is mobile to the direction far from solar panels to be tested to drive clamping limb for clamp drive mechanism, and turns an angle,
Until solar panels edge to be tested to be left to the first limiting slot of the first limiting section of clamping terminal, and the folder in the first limiting slot
Sheet reset；
8.2) top edge of solar panels and lower edge by respectively in the first limiting slot clamping plate and the second limiting section contact；
8.3) clamp drive mechanism driving clamping limb overturns 180 degree；
8.4) both ends of solar panels to be tested are respectively placed on the first limiting section of clamping terminal；
8.5) direction that clamp drive mechanism drives clamping limb to close solar panels to be tested is mobile, until by the sun to be tested
Energy edges of boards edge is caught in the second limiting slot of the second limiting section of clamping terminal, and the clamping plate in the second limiting slot clamps it.
