Claim 7:
8. The device for testing flatness according to claim 5, further comprising a control apparatus, a positioning apparatus and a second lifting apparatus, wherein the control apparatus is respectively connected to the positioning apparatus and the second lifting apparatus;
the second lifting apparatus is used to drive the platform storage to move in a third direction;
the control apparatus is used to, before the control apparatus controls the platform transmission mechanism to transport the testing platform assembled on the base to the second storage space, control the second lifting apparatus to drive the platform storage to move in the third direction until the positioning apparatus detects that the testing platform assembled on the base is aligned with the second storage space;
the control apparatus is also used to, before the platform transmission mechanism transports the standby testing platform stored in the first storage space to the base, control the second lifting apparatus to drive the platform storage to move in the third direction until the positioning apparatus detects that a position of the standby testing platform stored in the first storage space matches a position of the base.
