Abstract

The invention provides a photo gripping device, comprising a pedestal at least, wherein the pedestal is provided with an arm, the arm is provided with a unit capable of producing gripping deformation, and the effective deformation part in the gripping unit is made by photoinduced deformation material. The invention also provides a gripping method, namely light irradiates the photoinduced deformation material on the gripping unit of the gripping device to cause the gripping unit to deform, so as to realize gripping function. The actuating mechanism and operation mechanism of the photo gripping device in the invention are relatively simple, the size can be relatively small; and the gripping device provided by the invention has the advantages of being fast, precise, environmental-friendly and low in energy consumption and has the characteristics of not belonging to other driving modes such as remote manipulation and the like.

Description

technical field [0001] The invention relates to the technical field of materials and automation, in particular to a grasping device and a grasping method directly controlled by light. Background technique [0002] The grabbing device is an important structure and key part of the automation device. The traditional grabbing device uses a servo motor as a driver, and transmits the motion of the servo motor to the end of the automation device through a transmission mechanism, or uses pneumatic, hydraulic and other driving methods. , which requires the automation device to have many related equipment such as motors, gears, conveyor belts, etc. The existence of these devices seriously restricts the miniaturization of the automation device, and the intervention of motors and gears makes the control system of the automation device more complicated. There are also some other driving methods. For example, some people apply shape memory alloys to grasping devices, but shape memory allo...
