Background technique
For heavy-duty machineries such as shipbuilding, ocean engineering, bridge steel structure, steel building, chemical machinery and hoisting machineries
Manufacture it is most of be not batch production, most of is individually to produce, seldom processed, assembled using standardized production line,
Manufacture.Because the hardware overall dimensions of these industries are big, weight is heavy, different, the complicated seldom use of crossbar structure
Fixed frock clamp is assembled, welding process there are many in the enclosure space of metal structure or hemi-closure space into
Row, most of weld seam are fillet weld in the flat position and fillet weld in the vertical position, and causing these industries substantially does not have and the seldom fixed industry of application is welded
Welding robot is all to rely on many welders and be moved to the position of metal structure welding to weld.
Currently, electric welding skilled worker's labour cost of enterprise rises year by year, and it is welded this arduous labor and is ready dry people
Fewer and fewer, the good electric welding skilled worker of technology is increasingly difficult to look for.And human weld's unstable quality, low efficiency.But enterprise product
Competition it is but more and more stronger, product requirement is higher and higher, and product quality is more and more tighter.This is increasing from now on to contradiction, only
It just can effectively solve by a kind of moveable Intelligent welding robot.But it is special due to above-mentioned industry metal structure, zero
The phenomenon that position while welding caused by the reasons such as construction, deformation and gap deviation very more, metal structure slab structure is assembled in part processing
The multilayer multiple tracks continuous arc welding of part, the kinetic control system control welding gun for depending merely on welding robot move not along the path of weld seam
The problem of automatic welding can be fully solved, will also automatically adjust device by welding seam automatic tracking device and welding procedure.
Sensor is the key component of seam tracking system.Its effect is the location and shape for being accurately detected weld seam
Information is simultaneously converted into electric signal.Control system could be handled signal, and control automatic adjusting mechanism according to testing result
Welding torch position is adjusted, to realize soldering joint automatic tracking.
It generally can be divided into direct-arc formula, contact and contactless three categories.Mechanical, machine can be divided by working principle
Electricity, electromagnetism, capacitor, jet stream, ultrasound, infrared, photoelectricity, laser, vision, electric arc, spectrum and optical fiber type etc..It is several frequently seen below
Weld seam tracking sensor:
Touch sensor is the sensor used earliest, feature be not by electric arc interference, reliable operation, at low cost,
Once it was used widely in production, but since tracking accuracy is not high, abrasion is big, easily-deformable, is not suitable for high-speed welding, at present
Replaced by other method for sensing.
Ultrasonic sensor is not afraid of electromagnetism, light, flue dust interference in welding, but is easy by noise jamming, to noise ratio
It is more sensitive, such as have certain limitation in the application of CO2 gas shielded arc welding welding method.
The working principle of arc sensor is in the welding process, when the relative position between welding gun and workpiece changes
When, the variation of arc voltage and electric current can be caused, these variations all can serve as characteristic signal and be extracted realization welding gun height
Low and left and right both direction tracing control.But for no symmetrical side or at all without the joint form of side wall, existing electric arc
Sensor cannot then identify.
Photoelectric sensor precision is high, reproducibility is good, may be implemented to bevel shape, width and the detection in section and weld seam with
Track provides foundation for the self adaptive control of welding parameter.Photoelectric sensor can be divided into the single-point based on discrete photoelectric cell again
Formula photoelectric sensor and the visual sensor that groove image information can be obtained.
It is different according to the working method of welding robot vision welding system, can will be used for welding robot vision weld joint with
The visual sensor of track system is divided into 3 kinds: structure light formula, laser scan type and directly shooting arc type.Currently, have in the market compared with
More laser scan type welding robot vision weld joint tracking systems, but price is generally all somewhat expensive.The tracking of butt weld is imitated
Fruit is preferable, but less desirable to the tracking effect of fillet weld.And it is overproof to weld gap to automatically adjust welding procedure this
Aspect effect is also not highly desirable.
