Abstract

The invention relates to a clamping jaw mechanism and a mechanical arm. The clamping jaw mechanism comprises a machine frame, a driving mechanism and clamping jaw assemblies. The machine frame is provided with arc-shaped rails. The driving mechanism and the clamping jaw assemblies are arranged on the machine frame. The driving mechanism is in driving connection with the clamping jaw assemblies. Each clamping jaw assembly comprises a matching part which is matched with the corresponding arc-shaped rails. The clamping jaw assemblies can be driven by the driving mechanism to move along the arc-shaped rails through the matching parts. The motion trails of the clamping jaw assemblies provided by the embodiment of the invention are in an arc shape, thus, articles in irregular shapes can be clamped, article clamping can be achieved in a larger dimension range, accordingly, the clamping jaw mechanism and the mechanical arm can adapt to the overall dimensions of more articles, and the work adaptation under different occasions is improved.

Description

technical field [0001] The invention relates to the field of warehousing and logistics, in particular to a claw mechanism and a mechanical arm. Background technique [0002] Pneumatic grippers are widely used in industrial automation, logistics, medical and biological industries. Among them, the application in the logistics industry is mainly used as the end effector of the parallel robot or the six-axis mechanical arm, that is, the end picker. Combined with the visual recognition system, the items on the belt sorting line are sorted. [0003] Pneumatic grippers generally include parallel opening and closing type pneumatic grippers, sliding rail type pneumatic grippers, rack type pneumatic grippers, etc. The cylinder or rack pushes the jaws horizontally to achieve the purpose of clamping objects. Under the action of the parallel cylinder, the end of the gripper only moves horizontally, and can only grip items with regular shapes and larger sizes. For the clamping of irre...
