Clamping equipment for optical element and clamping method thereof

The invention discloses clamping equipment for an optical element and a clamping method thereof. The clamping equipment comprises a discharging assembly used for containing a cylindrical glass rod, a feeding assembly used for conveying the cylindrical glass rod to an optical element clamping mechanism and a loading assembly used for installing the cylindrical glass rod into the optical element clamping mechanism; the clamping method comprises the steps that a plurality of cylindrical glass rods are sequentially placed on a material disc according to the sequence and moved to a position below a pneumatic adsorption transfer mechanism of the feeding assembly; the pneumatic adsorption transfer mechanism moves the adsorbed cylindrical glass rods to the position above a transition material frame and moves the cylindrical glass rods to the optical element clamping mechanism; S5, a clamping plate separating assembly lifts clamping blocks; a pushing assembly pushes the cylindrical glass rods on the transition materia
