Description

Technical Field

[0001] The utility model belongs to the field of glass production lines, and particularly relates to a glass suction and transfer device. Background Art

[0002] When glass is manufactured, it needs to be grasped and transferred. Since the glass itself is relatively smooth, currently, the method of using vacuum suction cups for grasping is adopted. The principle is that after several suction cups are attached to the glass surface, the vacuum machine evacuates the air inside the suction cups to form a vacuum, thereby obtaining sufficient adsorption force. When grasping glass of different sizes, it is usually necessary to adjust the adsorption position of the suction cups. In the prior art, there is a scheme of installing the suction cups on linear guide rails. Four suction cups respectively correspond to four guide rails and their motors. Since there are more motors for controlling the suction cups, the load of the entire manipulator will increase. Therefore, how to reduce the weight of the adjustment mechanism and how to simplify the adjustment process are all problems worthy of research. Content of the Utility Model
