According to the employed commutator segment interdeep detector of the detection method of above-mentioned commutator segment interdeep, comprise pallet, frame, the commutator wheelwork is housed above described pallet, below pallet and with the corresponding position, position of commutator wheelwork driven shaft is housed, driven shaft and cylinder link; Side at described pallet is equipped with vision sensor, vision sensor and image processor link, image processor and touch display link, described cylinder, commutator wheelwork, image processor and vision sensor link with microcomputer controller respectively, and microcomputer controller also links with switch.
After adopting the present invention, compare with the range estimation detection of routine, precision of the present invention and sensitivity are all very high, can detect a lot of problems in the commutator segment interdeep at one time, can be used for producing in enormous quantities line, prevent that effectively the bad quality problems of groove between sheet from appearring in the commutator product, reduce the labour, reduced production cost, improved the accuracy rate that detects, guarantee product quality, satisfied client's high request.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of commutator segment interdeep detector of the present invention.
Fig. 2 is the left side view of Fig. 1.
Five, embodiment
With reference to accompanying drawing, the detection method of commutator segment interdeep of the present invention is: at first, it (can be round tray that commutator product 5 to be detected is put into pallet 10, have the locating slot of placing commutator on this round tray) on, the upper and lower center hole of commutator withstood respectively by the driven shaft 12 of the active mandrel 4 of the commutator wheelwork 11 of commutator top and pallet below; Then, start touch display 1 and switch 2, enabling signal is sent instruction through microcomputer controller (PLC) 8 and is sent to commutator wheelwork 11 and makes its work, makes commutator along with active mandrel 4 and driven shaft 12 (can be controlled by cylinder) rotate together; In the commutator rotary course, after vision sensor 6 is sensed commutator segment interdeep, the electronic shutter of instantaneous triggering vision sensor is facing to the commutator segment interdeep generation visual signal of taking pictures continuously, again the visual signal of obtaining being sent to image processor 7 handles, image processor 7 carries out whether qualified judgement according to original commutator segment interdeep test item of setting (being qualified data area) to commutator, and should whether qualified information send microcomputer controller (PLC) 8 to, and reflect testing result by touch display 1, the then demonstration " OK " that meets (promptly passing through) exceeds above-mentioned setting range and then is judged to be " NG " (being writing a Chinese character in simplified form of NOT GO: do not pass through); Simultaneously, in testing process, it is consistent with the commutator segment sheet number of commutator that the number of times of taking pictures is responded in the vision sensor triggering, in case the commutator product that leak-stopping mills is by detecting.
Wherein, before vision sensor 6 was sensed commutator segment interdeep, commutator rotated at a slow speed earlier, treat that vision sensor 6 is sensed commutator segment interdeep after, commutator is accelerated rotational speed, and adapts with the speed of taking pictures of vision sensor; Getting of each commutator segment interdeep a little generally is at least five points, i.e. two points in top of groove between sheet, its point in middle part, two points in its underpart.
According to the employed commutator segment interdeep detector of the detection method of above-mentioned commutator segment interdeep, comprise pallet 10, frame 15, commutator wheelwork 11 is housed above described pallet 10, below pallet 10 and with the corresponding position, position of commutator wheelwork, driven shaft 12 is housed, driven shaft 12 links with cylinder 13, the upper and lower part of pallet 10 links with bracket tray positioning apparatus 18, pallet whirligig 14 respectively, is used for pallet is rotated, locatees with convenient and detect; Side at described pallet 10 is equipped with vision sensor 6 (vision sensor 6 is contained on the sensor frame 17), vision sensor 6 links with image processor 7, image processor 7 links with touch display 1, described cylinder 13, commutator wheelwork 11, pallet whirligig 14, bracket tray positioning apparatus 18, image processor 7 and vision sensor 6 link with microcomputer controller (PLC) 8 respectively, and microcomputer controller (PLC) 8 also links with switch 2.
Wherein, touch display 1, switch 2 can be contained in the top of frame 15; Worktable 16 can be equipped with in the bottom of frame, is used to place cylinder 13, pallet whirligig 14 (for prior art), sensor frame 17, and image processor 7, microcomputer controller (PLC) 8 can be contained in the worktable 16; Support 3 can be equipped with in the middle part of frame, is used to place commutator wheelwork 11, bracket tray positioning apparatus 18 (being prior art), and commutator wheelwork 11 can be linked successively by motor 20, intermediate transmission mechanism 21, active mandrel 4 etc. and constitute; Pallet can be round tray, has the locating slot that several place commutator on this round tray, can place a plurality of commutators simultaneously and detect.Alarm lamp 19 can be equipped with in top in described frame 15, and alarm lamp 19 links with image processor 7, microcomputer controller (PLC) 8 respectively.
When commutator detects, the work of pallet whirligig is rotated in place pallet, and position by bracket tray positioning apparatus. then, cylinder operation drives the following center hole that driven shaft withstands commutator, the work of commutator wheelwork drives the last center hole that the active mandrel withstands commutator. then, according to above-mentioned detection method groove between commutator segment being detected. image processor carries out whether qualified judgement according to original commutator segment interdeep test item of setting (being qualified data area) to commutator, if exceed above-mentioned setting range then be judged to be " NG ", at this moment, alarm lamp is reported to the police and underproof commutator is separated rejecting.
Commutator segment interdeep test item of the present invention has: groove quantity between sheet, size, big sulculus, flared channels, slotless or mica sheet is residual, groove edge stain, trough rim burr (these three internal soundness problems can be expressed by the stain difference on the picture) etc.; Also be applicable to the commutator product of virtually any size size, any structure characteristics.In image processor, microcomputer controller (PLC) internal system, the check decision condition of multiple product can be preserved.During use, the condition according to different product selections is consistent has so not only guaranteed efficient, also guarantees multiple batches of consistency of product problem simultaneously.The commutator segment interdeep data area of setting should all answer test item corresponding with commutator segment interdeep.
