Claim 15:
16. The system for testing flatness according to claim 15, wherein the platform transmission mechanism comprises a plurality of first rollers, a plurality of second rollers, a plurality of third rollers, a plurality of fourth rollers, a first transmission belt, a second transmission belt, a third transmission belt, a fourth transmission belt, a fifth transmission belt, a sixth transmission belt, a first motor and a second motor;
the base is disposed between the first transmission belt and the second transmission belt, and the platform storage is disposed between the third transmission belt and the fourth transmission belt;
the first motor is used to drive the first transmission belt to rotate, and the second motor is used to drive the second transmission belt to rotate;
the first transmission belt is used to drive the plurality of first rollers to roll, and the second transmission belt is used to drive the plurality of second rollers to roll;
the fifth transmission belt is sleeved on one of the first rollers and one of the third rollers, and when the plurality of first rollers roll, the fifth transmission belt drives the plurality of third rollers to roll;
the sixth transmission belt is sleeved on one of the second rollers and one of the fourth rollers, and when the plurality of second rollers roll, the sixth transmission belt drives the plurality of fourth rollers to roll;
when the platform transmission mechanism transports the testing platform assembled on the base to the second storage space, the plurality of first rollers are disposed below the testing platform assembled on the base and in contact with the testing platform assembled on the base; the plurality of second rollers are disposed below the testing platform assembled on the base and in contact with the testing platform assembled on the base; and the plurality of third rollers and the plurality of fourth rollers are disposed below the second storage space; the first motor drives the first transmission belt to rotate; and the second motor drives the second transmission belt to rotate to drive the plurality of first rollers, the plurality of second rollers, the plurality of first rollers, and the plurality of fourth rollers rotate and transport the testing platform assembled on the base to the second storage space;
when the platform transmission mechanism transports the standby testing platform stored in the first storage space to the base, the plurality of third rollers are disposed below the standby testing platform stored in the first storage space, and in contact with the standby testing platform stored in the first storage space; the plurality of fourth rollers are disposed below the standby testing platform stored in the first storage space, and in contact with the standby testing platform stored in the first storage space; the plurality of first rollers are aligned with the plurality of third rollers; the plurality of second rollers are aligned with the plurality of fourth rollers; the first motor drives the first transmission belt to rotate, and the second motor drive the second transmission belt to rotate to drive the plurality of first rollers, the plurality of second rollers, the plurality of third rollers, and the plurality of fourth rollers to rotate and transport the standby testing platform stored in the first storage space to the base.
