Abstract: A pneumatic clamping device includes a main body, a piston, a first linkage member and a second linkage member. The main body includes a chamber. The piston includes a pillar part. The first linkage member includes a first arm part and a second arm part. The second linkage member includes a third arm part and a fourth arm part. When the air is introduced into the chamber, the pillar part is gradually moved to push the first arm part and the third arm part, so that the second arm part is externally expanded relative to the fourth arm part. When the air is exited from the chamber, the pillar part is gradually moved to pull back the first arm part and the third arm part, so that the second arm part is internally retracted relative to the fourth arm part.

Abstract: An active alignment machine includes a base, a first pillar, a second pillar, a distribution module, a first alignment module, a second alignment module and a third alignment module. The first pillar has a first pillar top surface. The second pillar has a second pillar top surface. The first pillar top surface and the second pillar top surface cooperatively support plural assembling specifications. The distribution module is installed on the base and arranged between the first pillar and the second pillar. The first alignment module, the second alignment module and third alignment module are replaceable to be assembled with or dissembled from the first pillar top surface and the second pillar top surface. The first alignment module, the second alignment module and third alignment module work with the distribution module to perform the active alignment on a first-type product, a second-type product and a third-type product, respectively.
