Problems solved by technology

The existing flexible end clamping structure is generally supported by a metal rigid skeleton, and relies on the deformation of the elastic material to meet the effect of flexible grasping. This structure more or less produces a large normal pressure on the surface of the grasping object, which may cause Damage to fragile and vulnerable objects, poor safety performance

Abstract

An electromagnet drive flexible glue adhering gripping device comprises a linear guide rail. A sliding block is mounted on the linear guide rail. An electromagnet is fixed to the lower portion of the linear guide rail. A transverse rod is fixed to the sliding block. An iron block is fixed to the transverse rod. A spring is fixed between the sliding block and the electromagnet. A flexible glue body is fixed under the electromagnet. The two ends of the flexible glue body are connected with the two ends of the transverse rod through stay cords. The sliding block can move on the linear guide rail, when the electromagnet is not electrified, the transverse rod is separated from the electromagnet through elastic force of the spring, the stay cords at the two ends of the transverse rod pull the flexible glue body open. When the electromagnet is electrified, the transverse rod is pulled down, a permanent magnet block embedded in the flexible glue body and the electromagnet reprehend each other, and thus materials are gripped. The wrapping force of the flexible glue body to the materials is increased by embedding the permanent magnet block, so that the materials are gripped more reliably.

Description

technical field [0001] The invention relates to a material grasping device, in particular to a flexible adhesive adhesion grasping device driven by an electromagnet. Background technique [0002] In terms of object grasping, the traditional method is to use a mechanical gripper structure or a vacuum suction cup, but these common techniques have some defects. The mechanical gripper realizes the clamping action of the object through the precise control of each mechanical part. To achieve this action, it needs to mechanically "squeeze" the contact surface of the object. Clamping of damaged objects. Vacuum suction cups also have many limitations when grabbing objects. For example, the application of vacuum suction cups requires the surface of the object to be grasped to be smooth, dry and clean, which also limits the application of vacuum suction cups. [0003] The adhesion and grasping of objects play an important role in the field of automated manufacturing. The existing fl...
