Description

The industry spray robot

Technical field

The utility model relates to a kind of spraying equipment, the spray robot that uses in particularly a kind of industry.

Background technology

Along with the develop rapidly of machinery manufacturing industry, the spraying technology supporting with it is also progressively developed, progressively carries out the transition to the full-automatic spray robot from hand spray, the spraying of semi-automatic spray gun; In the spraying operation process, adopt Robotics, not only can improve working environment, reduce labor intensity; But also can increase work efficiency; The spraying homogeneous quality is good, and the paint loss is little, so receive liking of manufacturing enterprise and numerous workers deeply.

At present common spray robot mainly contains two kinds of serial machine robot mechanism and parallel robot mechanisms.The serial machine robot mechanism is the motion open chain, thereby shortcomings such as little, bearing capacity difference are arranged such as rigidity, has big working space and action comparatively flexibly.And parallel robot mechanism is because of adopting the mechanical closed loop structure, and low, the good rigidity of the inertia of motion parts is compared advantage such as have the positioning accuracy height, bearing capacity is strong with the serial machine robot mechanism, but have shortcomings such as working range is little, underaction.

For this reason, many manufacturers and knowledgeable people have carried out research to the problems referred to above and have sent out and open, but do not have rational product to emerge so far as yet.

Summary of the invention

In order to overcome the problems referred to above that existing spray robot exists, the purpose of the utility model provides that a kind of simple and reasonable, flexible and convenient operation, firm and reliable connection, coating quality are good, the industrial spray robot of high efficiency.

The utility model solves the technical scheme that its technical problem adopted; It comprises fixed head, left and right arms servomotor, arm four bar parallel institutions, wrist diaxon serial mechanism, and left and right arms servomotor correspondence is installed on the fixed head, and described arm four bar parallel institutions comprise left and right sides upper arm, left and right sides underarm, wrist seat; Left upper arm and left underarm are hinged; Right upper arm and bottom right arm are hinged, and the other end of right upper arm is connected with right arm servomotor output shaft, and the other end of bottom right arm is fixedly connected with the wrist seat; The other end of left upper arm is connected with left arm servomotor output shaft, and the other end of left underarm is hinged on the wrist seat.

Described wrist diaxon serial mechanism comprises radial servo motor, axial servomotor, Connection Block, spray gun holder; The radial servo motor is installed on the wrist seat; Its output shaft is fixedly connected with Connection Block; Axially the output shaft of servomotor is fixedly connected with Connection Block, and the spray gun holder is fixed on the axial servomotor, and spray gun holder and axial servomotor Connection Block relatively rotate up and down.

The output shaft of said radial servo motor is vertical each other with the output shaft of axial servomotor.

After adopting said structure; With prior art following advantage and effect are arranged relatively: the one, because arm segment adopts plane four rod parallel connection structures, wrist partly adopts the diaxon cascaded structure, cooperates the control system again; Make the utility model possess the advantage of serial machine people and parallel robot simultaneously; Positioning accuracy is high, bearing capacity is strong, flexible operation, and control is convenient.The 2nd, can change the optional position that attitude arrives five planes, thus be fit to very much only require the industrial products spraying on five planes, easy for installation, economical and practical.
