Substrate and mask attachment clamp device

A substrate and mask attachment clamp device, comprising;

• a push assembly;
• an upper clamp mechanism, comprising:
• a first reciprocating assembly, comprising a first inclined surface and a swing element;
• a second reciprocating assembly, comprising a second inclined surface and a sliding surface;
• and
• a lower clamp mechanism, comprising:
• a lower clamp retainer;
• and
• a clamp movably disposed on the lower clamp retainer;
• wherein, during the process of the push assembly moving along a first direction, the push assembly moves with respect to the first inclined surface to drive the first reciprocating assembly to move along a second direction, the push assembly further drives the second inclined surface to move with respect to the swing element so as to drive the clamp to move along a third direction opposite to the first direction and drives the sliding surface to move with respect to the lower clamp mechanism so as to drive the clamp to move along a fourth direction, and the first direction, the second direction and the fourth direction are substantially perpendicular to each other.
