Specific embodiment
Below in conjunction with the accompanying drawings invention is described in further detail.
As shown in figure 1, a kind of full-automatic accurate short steel pipes quality detecting system, controls including PLC control system 1 and PLC
The host computer 2 and the fully-automated synthesis platform 3 being connected with PLC control system 1 and host computer 2 respectively of the connection of system 1.
Wherein, PLC control system 1 includes CPU, power supply, input module and output module, and the totality for completion system is patrolled
Collect control.Fully-automated synthesis platform 3 includes industrial camera, light source, motor, direct current generator, photoelectric sensor, force feedback
Sensor, encoder, actuating device, machinery, for completing the acquisition of detection signal, drive the fortune of detection means and short tube
Dynamic.Host computer 2 is industrial computer, comprising a set of image processing software and a set of number management software in host computer 2；Image procossing is soft
Part is used for the process and analysis of the picture for completing industrial camera shooting, judges that steel pipe outward appearance whether there is defect；Number is managed
Software is used for realizing the real-time display of steel pipe non-defective unit number and defective products number, statistics and storage on production line.
The workflow of the present invention is as shown in Fig. 2 tested steel pipe 4 is pressed from both sides by a mechanical hand 5 equipped with force feedback sensor
Control is held, mechanical hand 5 drives movement by guide rail 6, there are horizontal and vertical two degree of freedom.Comprise the following steps that：
1) automated cleaning.Now tested steel pipe 4 is in low order end.Automated cleaning part 7 completes the automated cleaning of steel pipe, just
In follow-up detection and packaging.Cleaner has inner core and overcoat two-layer, respectively the inner surface and outer surface of cleaning steel pipe, cleaning
Material is using the soft brush (such as flannelette brush) for not damaging steel tube surface.When steel pipe moves to this station, soft brush 9 is controlled by motor 8 and is moved
And rotation, complete to clean, reach detection required cleaning standard, but do not damage product surface.
2) outward appearance detection.Now tested steel pipe 4 is moved to left to the second station.Outward appearance detection part 10 passes through industrial vision technology
Realize, steel pipe outward appearance is shot using industrial camera, by the image processing software and algorithm in industrial computer 2 to captured
Photo is carried out processing, is analyzed, and detects steel pipe outward appearance with the presence or absence of defects such as pit, pitted skin, rust staining, cuts.Short tube outer surface
Being shot by a line scan camera, being aided with strip source, short tube is rotated along axle center, the whole appearance of short tube is made using line scan camera
Face forms a width plane graph.Short tube inner surface is shot from end face by industrial camera, provides illumination by collimated backlight light source, then to institute
The picture for photographing carries out software correction and analysis.
The image of taken outer surface of steel tube and with software processes after effect, as shown in Figure 3.Taken steel
The image of pipe internal surface and with software processes after effect, as shown in Figure 4.After using algorithm process, can determine whether out whether there is
Defect.
3) inner diameter measurement.Tested steel pipe continues to move to left a station.Using diameter meet error requirements small one and large one two
The metal ball 11 of individual fixation detects that to pipe diameter clamping steel pipe 4 with mechanical hand 5 and up moving, steel pipe 4 integrally can be packed into
Lower section spheroid but can not cover top spheroid, then judge pipe diameter size qualification, otherwise unqualified.During using mechanical hand 5
On force feedback sensor and platform on photoelectric sensor judging whether steel pipe 4 packs into spheroid.
4) external diameter detection.(step-like structure, after port of export internal diameter is more than to meet a two-stage of error requirements using internal diameter
End internal diameter) the cylindrical metal ring 12 of fixation outer diameter of steel pipes is detected, clamp steel pipe 4 with mechanical hand 5 and up move, steel
Pipe 4 can integrally be filled in the port of export of becket 12 and fill in again and not enter rear end, then judge outer diameter of steel pipes size qualification, otherwise unqualified.
During judge whether steel pipe fills in metal using the photoelectric sensor on the force feedback sensor and platform on mechanical hand 4
Ring.
5) length detection.(step-like structure, right-hand member shoulder height is higher than to meet a two-stage of error requirements using height
Left end shoulder height) metal cover board 13 length of steel pipe is detected, clamp steel pipe 4 toward moving left with mechanical hand 5, steel pipe 4
The right-hand member step that metal cover board 13 can be integrally moved into is moved again and does not enter its left end step, then judge outer diameter of steel pipes size qualification, otherwise
Unqualified.During judge whether steel pipe moves using the photoelectric sensor on the force feedback sensor and platform on mechanical hand 5
Enter metal cover board.
6) count automatically.Qualified and underproof product, system is checked to count automatically simultaneously through above-mentioned all detecting steps
In display, storage and management that host computer carries out data.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
