Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with concrete real Execute example, and referring to the drawings, the present invention is described in more detail.
Fig. 1 is the schematic diagram of the paint finishing of view-based access control model location according to an embodiment of the invention.
The present invention view-based access control model location paint finishing include one or more spraying equipment, one or Multiple vision localization harvesters 102, vision localization processor 103.
It should be noted that four shown in Fig. 1 spraying equipment is only example, the base of the present invention Paint finishing in vision localization can use one, two, three, five or more spraying to set Standby.Shown in Fig. 1 eight vision localization harvester 102 is only example, the present invention based on The paint finishing of vision localization can use the vision localization harvester 102 of eight above and below. The workpiece 104 of the rectangle shown in Fig. 1 is only example, the spraying of the view-based access control model location of the present invention The workpiece of difformity and size can be sprayed by system.Workpiece mentioned by the present invention can wrap Include any article that can be sprayed-on, such as, part, equipment, building materials etc..Shown in Fig. 1 The vision localization processor 103 being positioned at spraying equipment side is only example, vision localization processor 103 can be installed in any suitable location.
Specifically, each spraying equipment is arranged at workpiece side to spray workpiece 104.This Skilled person is appreciated that and can arrange multiple spraying equipment in the side of workpiece 104.Such as figure Shown in 1, when workpiece 104 oversize, multiple spraying equipments can be arranged on workpiece 104 The same side workpiece 104 is sprayed.
Preferably, each spraying equipment all includes: base support 105, and it is installed on ground or side In cabin;Guide rail 106, it is arranged on base support 105;Spray equipment 101, it is arranged on leads Move on rail 106 and on guide rail 106, workpiece 104 is sprayed, and receiving position deviation Value.Preferably, base support 105 is bolted on ground or in shelter.
Preferably, one or more (in Fig. 1 being eight) vision localization harvesters 102 are arranged at Workpiece 104 around, gathers the positional information of the characteristic point of workpiece 104 and generates corresponding vision letter Number.Preferably, one or more vision localization harvesters 102 can be installed on workpiece 104 periphery Equipment on.Such as, one or more vision localization harvesters 102 can be installed on workpiece 104 On the spraying equipment of periphery.Characteristic point is the upper changeless feature of described workpiece (with a workpiece), And each characteristic point is arranged in the coverage of corresponding vision localization harvester 102.Example As, in eight vision localization harvesters 102 in Fig. 1, each vision localization harvester 102 Can photograph in the whole characteristic points on workpiece is one or more.Such as, characteristic point can be work Hole on part or the artificial feature etc. pasted.Preferably, workpiece has at least four characteristic point.Ability Field technique personnel are appreciated that according to practical situation, and it is also feasible that workpiece is less than four characteristic points.
Preferably, vision localization processor 103 receives one or more vision localization harvester 102 The visual signal generated, and calculate according to the ideal position information of the characteristic point of the workpiece 104 prestored The position deviation value of workpiece 104, and adjust each spraying equipment and workpiece 104 according to position deviation value Between position relationship.Adjust the position relationship between each spraying equipment and workpiece 104 not only Refer to adjust the resting position relation between parts and the workpiece 104 that the carrying out in spraying equipment sprays, Also refer to adjust parts that the carrying out in spraying equipment the spray road when workpiece 104 is sprayed Footpath.Preferably, the position relationship between each spraying equipment and workpiece 104 also refers to spraying The initial position of device 105 and spraying path.Therefore, each spraying equipment and workpiece 104 are adjusted Between position relationship so that spraying equipment will not be by workpiece 104 when spraying workpiece 104 The impact of position deviation, and just can be automatically performed predetermined spraying operation without manual intervention.
In one embodiment, when workpiece 104 enters spray station, physical location may be with default There is deviation in stop place (theoretic position), therefore causes the physical location of the characteristic point of workpiece Deviation is produced, it is impossible to carry out automatic spraying operating with the theoretical position of characteristic point.Therefore, enter at workpiece After entering setting position, the position of workpiece 104 is acquired by vision localization harvester 102, i.e. The positional information of acquisition characteristics point, and it is transferred to vision localization processor 103 by signal.Vision is fixed Bit processor 103, according to the ideal position information of the characteristic point of the workpiece 104 prestored therein, enters Row analyzing and processing also calculates position deviation value, and by signal, position deviation value is sent to spray equipment 101.Spray equipment 101 adjusts initial position and the spraying path of self according to position deviation value.Excellent Selection of land, when spray equipment 101 is spray robot, adjusts flush coater automatically according to position deviation value The initial position of device people and spraying path.Therefore, according to the positional information of the fact characteristic point of workpiece, Initial position and follow-up spraying path poses to spray equipment are automatically adjusted, it is achieved without manually The intelligent automatic spraying technology intervened.
