With in the process, manipulator needs move to certain height with vision collecting system together, are just avoided that compressor of air conditioner sheet
Body blocks location hole.This mode, manipulator needs are moved to higher height, and manipulator is in the movement model of short transverse
Enclose it is larger, but for assembling process, as long as manipulator slightly above compressor of air conditioner, in a wide range of of short transverse
Movement is entirely lost motion, greatly reduces efficiency of assembling.For shape, two cylinders of compressor of air conditioner are larger, three
A mounting hole is smaller, and dispersion in big field range, small target auto-orientation are belonged to the vision positioning of mounting hole.At present in technology,
The spaced point of mounting hole to similar compressor of air conditioner etc, lacks simple, effective vision collecting device, can not meet life
Production, requirement.
