The invention provides an adsorption type longitudinal glass breaking and separating device. The adsorption type longitudinal glass breaking and separating device includes: a support platform and a lifting mechanism for driving the supporting platform to lift; a glass breaking mechanism arranged on the center of the supporting platform; two groups of glass separating mechanisms which are symmetrically distributed on two sides of the glass breaking mechanism; two groups of adsorption mechanisms which are symmetrically distributed on two sides of the glass breaking mechanism, wherein each adsorption mechanism includes an adsorption bracket, a vacuum-pumping system and a vacuum breaker valve, the adsorption bracket is fixedly connected to a movable platform, a top surface of the adsorption bracket is an adsorption surface contacting glass and has a plurality of adsorption holes, the adsorption holes are connected to the vacuum-pumping system through an adsorption channel, and the vacuum breaker valve is arranged on the adsorption channel. During a whole glass breaking and separating process, the glass does not contact glass conveying rollers, sliding abrasion between a bottom surfaceof the glass and the glass conveying rollers can be avoided, and the production quality of the glass is improved.
