Small soft-bodied air-suction type gripper device

Abstract

The invention discloses a small soft-bodied air-suction type gripper device which comprises a suction disc and connecting piece part and a pneumatic deformation control part; the suction disc and connecting piece part comprises a suction disc and an air pipe; the suction disc is connected with the front end of the air pipe through a connecting piece; a connecting end connected with a vacuum generator is arranged at the tail end of the air pipe; the pneumatic deformation control part comprises elastic joints and rigid plastic gaskets; the elastic joints are arranged on the part, between the connecting piece and the connecting end, of the air pipe in a sleeving manner; every two adjacent elastic joints are connected through one corresponding rigid plastic gasket; each elastic joint comprises a joint body made of elastic materials; a through hole through which the air pipe passes is formed in the center of each joint body; air chambers are formed in the periphery of the side edge of each joint body, and communicate with air passages communicating the outer wall of the corresponding joint body; and the air passages communicate with micro air flow drivers. The small soft-bodied air-suction type gripper device is rich in motion mode and good in flexibility, and is effectively applicable to the assembly of small parts.

Description

technical field [0001] The invention relates to a soft sucker device, in particular to a gripper device with elastic bending joints assembled in a small space. Background technique [0002] Vacuum suction cup, also known as vacuum spreader, is one of the actuators of vacuum equipment. Generally speaking, using vacuum suction cups to grab products is the cheapest method, so it is widely used in the industrial field. Commonly used vacuum suction cups include flat suction cups, corrugated suction cups, oval suction cups and special suction cups. The compact design and small internal volume of the flat suction cups minimize the gripping time and provide good stability when gripping workpieces. For handling flat or slightly dished workpieces with flat or slightly rough surfaces, such as: metal plates, cartons, glass plates, plastic parts and wooden boards. The corrugated suction cup has good adaptability to uneven surfaces and can gently grip fragile workpieces. For handling ...

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing sucker equipment, such as single motion mode, poor flexibility, and inapplicability to the assembly of small parts, the present invention provides a small soft air suction device with rich motion modes, good flexibility, and effective application for small parts assembly. The air-suction gripper rod part is designed based on the principle of elastic material deformation. It is driven and controlled by micro-flow gas. Compared with the motor-driven rotary joint, it saves more space and can be highly flexible in a small space. Motion, to achieve assembly operations where robots cannot enter the environment
