Robot hand grip for packaging and conveying dispersed materials

Abstract

The invention relates to a robot hand grip for packaging and conveying dispersed materials. The hand grip comprises a platform (1), a support frame (2), a sliding rail (3), N groups of fingers, a sliding block (7), a first connecting member (8) with a limit groove, air cylinders (9) and a second connecting member (10). The support frame (2) is fixed on the platform (1). The sliding rail (3) is fixed at the front side of the support frame (2). Each group of fingers comprises a small air cylinder base (4) with columnar embossments, a small air cylinder (5) and an executing part (6). The sliding block (7) is connected to the sliding rail (3) in a sliding manner. The adjacent N groups of fingers are connected by means of the first connecting member (8) with the limit groove. Columnar embossments on the small air cylinder base (4) having the columnar embossments of the N groups of fingers are spliced and matched with the limit groove of the first connecting member (8) having the limit groove. Two air cylinders (9) are fixed at the back side of the support frame (2) reversely. The invention can meet the need of grasping a plurality of dispersed materials once and can be used for adjusting space between the materials.

Description

technical field [0001] The invention relates to a gripper of a packaging and handling robot for scattered materials. It belongs to the technical field of packaging machinery. Background technique [0002] At present, the handling robots used in the packaging industry are mostly used for sorting, packing and palletizing. The corresponding hands are usually a single-finger gripper, a gripper with multiple synchronous fingers and a complex combination style gripper. The common feature of these hands is that the fingers of the gripper have synchronization, which is suitable for a single loose material or multiple neatly stacked materials. However, in actual production, we have encountered two situations in which the above grippers are not applicable: the first situation is to improve production efficiency, and it is necessary to realize the grasping of multiple scattered materials at one time; the second situation is to To achieve one-time grabbing of multiple materials, it i...

Problems solved by technology

However, in actual production, we have encountered two situations in which the above grippers are not applicable: the first situation is to improve production efficiency, and it is necessary to realize the grasping of multiple scattered materials at one time; the second situation is to To achieve one-time grabbing of multiple materials, it is usually necessary to use a sorting device with a sorting grid to sort the materials and then grab them with a manipulator. In order to adapt to products of different specifications, the size of the sorting grid is usually the size of the largest model product To achieve backward compatibility, which means that there will be a relatively large gap between the sorted small-size products, but due to the length of the carton or other container containing this group of materials or the size of the pallet with this group Dimensions are close at zero material clearance, so conventional grippers are not suitable
