The invention provides an automatic hook assembling device for double-glass frameless components and relates to the field of manufacture of solar cell components. The automatic hook assembling device comprises a substrate, a support arranged on the substrate and suction clamping devices arranged on the support. The support comprises two working platforms arranged symmetrically; two horizontal connecting cross rods are arranged between the two working platforms for connection and fixation; the two ends of the connecting cross rods are provided with connecting arms perpendicular to the connecting cross rods; the two ends of each connecting arm are provided with small telescopic oil cylinders; the tail ends of telescopic rods of the small telescopic oil cylinders are connected with suckers. With a double-glass component automatic clamping and bonding and compressing device, the working efficiency is greatly increased, the manpower cost is reduced, and most importantly, the manufacture precision is increased so that the quality of products is greatly improved; the device is suitable for industrialized application.
