Mechanical paw device of robot

Abstract

The invention discloses the mechanical paw device of a robot, which is structurally characterized in that in addition to two symmetrical groups of paws arranged on the two sides of a connecting plate, a group of catch pawls are arranged on the inner side of each group of paws, wherein, the two groups of catch pawls are parallel and symmetrical; the catch pawls, the paws and the driving cylinders of the paws are arranged on the moveable support on the two sides of the connecting plate; the moveable support is supported on a sliding guide mechanism and connected with the driving cylinders of the catch pawls, which are fixed on the connecting plate; and the sliding guide mechanism can be composed of a linear bearing support and a supporting guide rod. The mechanical paw device is used for grabbing soft packing bags full of bulk materials, particularly, the mechanical paw device allows the packing bags to accurately fall on the specified positions without deviation under the guiding action of the catch pawls, therefore, the packing bags can be laid in order and the application effect is good.

Description

technical field [0001] The invention relates to a robot manipulator, in particular to a robot manipulator claw device for grasping a flexible packaging bag filled with bulk materials. Background technique [0002] In production lines, warehouses, docks and other occasions, the robotic claws of robots are widely used to grab flexible packaging bags full of bulk materials, and then move them to designated positions. When placing the flexible packaging bag at a certain height vertically from the target position, since the existing manipulator claws only have two sets of rotatable claws, when the flexible packaging bag is thrown down, due to various reasons, such as the flexible packaging bag Uneven filling, poor posture when entering the hook grabbing position, asynchronous opening of the two sets of hooks or unbalanced force, etc., will often cause the falling point to deviate due to the lack of guiding movement during the falling process of the object, resulting in improper p...
