Embodiment Construction

[0046] Embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.

[0047] The seven-degree-of-freedom spraying robot of the present invention has redundant degrees of freedom and can meet the spraying requirements of large-sized and complex-shaped workpieces such as aircrafts and ships. Compared with the existing spraying robots, it has higher flexibility and can be applied to narrow Space work.

Abstract

The invention discloses a seven-freedom-degree spray coating robot. The seven-freedom-degree spray coating robot comprises a spray gun and a spray coating robot body. The spray coating robot body comprises a first joint, a first connector, a second connector, a third connector, a fourth connector, a fifth connector, a sixth connector and a seventh connector which are sequentially connected in series. Connection between all the connectors achieves rotation of the robot and spinning around the center axis of the robot body, so that spray coating operation is completed. The seven-freedom-degree spray coating robot can replace manual spray coating operation, lowers the labor cost, improves the spray coating efficiency, coating quality and coating precision and prevents paint mist from hurtingthe body of the operation personnel. The seven-freedom-degree spray coating robot can be freely assembled into a multi-freedom-degree long arm structure, the work range is wider than a universal typespray coating robot, and the seven-freedom-degree spray coating robot has redundancy freedom degree, high flexibility and good dynamic response and can meet spray coating requirements of large-sized complicated-profile workpieces such as an airplane and a ship.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a seven-degree-of-freedom spraying robot. Background technique [0002] Spraying robot is a relatively mature technology with many years of research and development history. During this period, many spraying robot companies emerged, such as ABB in Switzerland and Sweden, Yaskawa MOTOMAN in Japan, KUKA in Germany, etc. At present, ABB's spraying robots are widely used in the world, such as ABB IRB5500 spraying Robots are widely used in surface spraying operations of small and medium-sized parts such as automobiles, fixtures, and electronic products. Poor adaptability to surfaces and narrow spaces. [0003] At present, for the coating operations of large-scale and complex structural workpieces such as the outer surface of aircraft, the inner surface of aircraft pipelines, and the outer surface of ships, most manufacturing companies use manual spraying. This spraying method has low...
