Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Shown in accompanying drawing 1, retainer 1 mentioned in the present invention, refer to that the inside and outside surface formed after turning is sphere, two ends are the metal construction of plane.
As illustrated in figs. 2-7, retainer pros and cons discriminating gear of the present invention, comprises frame 11,
Described frame 11 is provided with retainer detent mechanism, retainer mechanism for identifying, the retainer sorting mechanism for locating retainer 11, and main control computer.
Described retainer detent mechanism, retainer mechanism for identifying, retainer sorting mechanism are installed in frame 11, and retainer mechanism for identifying is above retainer detent mechanism and mutually vertically, retainer sorting mechanism is in the below of retainer detent mechanism.
Described retainer detent mechanism comprises retainer locating piece 8, first cylinder 9, described retainer locating piece 8 connects the first cylinder 9 push rod, first cylinder 9 is fixed on above frame, first cylinder 9 number is two, and two first cylinder 9 one the first from left are arranged symmetrically, first cylinder 9 pushrod movement drives the motion of retainer locating piece 8, realizes the clamping of two retainer locating pieces 8 and loosens.
Described retainer sorting mechanism comprises retainer back up pad 23, inner baffle plate 14, outer baffle 15, convergence slot 12, retainer converge platform 16, reducing motor 22, the lower face coupling shaft Connection Block 20 of described retainer back up pad 23, and interfix.Transmission shaft 21, through axle Connection Block 20, also interfixes.The bearing fixing sleeve 19 that bearing is equipped with in the inside is fixed in frame 11, and transmission shaft, through bearing, is realized the circumference location of transmission shaft, bearing fixing sleeve 19 added a cover bearing gland 18, realize the axial location of transmission shaft by bearing.Transmission shaft one end connects reducing motor 22, and reducing motor rotates the positive and negative rotation that rotating realizes retainer back up pad; Described retainer converges platform 16, inside and outside two pieces of baffle plates 14,15 and convergence slot 12, interconnects, and the retainer after differentiation exports 10 by two, left and right groove from retainer and rolls out, and enters manufacturing procedure below.
Described retainer mechanism for identifying comprises lampshade 13, lampshade web joint 7, second cylinder 17, camera 2, camera bracing frame 3, screw mandrel slide block 5, screw mandrel 6, screw mandrel base 4, described lampshade 13 comprises annular LED lamp and tubular lamp housing, described lampshade 13 connects lampshade web joint 7, lampshade web joint is connected with the second cylinder 17 be fixed on above frame, and the second cylinder 17 moves and drives lampshade 13 to move up and down.Lampshade 13 is in the peak of movement travel when not working; Described camera 2 connects camera bracing frame 3, camera bracing frame 3 connection wire rod slide block 5, screw mandrel slide block 5 can move up and down on screw mandrel 6, screw mandrel is fixed on screw mandrel base 4, screw mandrel base 4 is connected with frame 11, have chute in screw mandrel base, ensure screw mandrel slide block 5 only to be moved up and down on screw mandrel 6, without other motion states.The peak of movement travel is in time camera does not have in harness.
The course of work of the present invention and principle as follows:
After retainer 1 to be discriminated is transported to retainer back up pad 23 by travelling belt, pusher pushes retainer back up pad 23 position retainer:
(1) two in frame the first cylinders 9 be arranged symmetrically are started working, push rod on first cylinder 9 promotes two retainer locating pieces 8 and moves together, after two retainer locating pieces 8 contact with retainer 1, two retainer locating pieces 8 continue to draw close to centre, until retainer 1 is clamped, at this moment retainer 1 is positioned in immediately below camera 2, after clamping, locating piece starts separately, to reset to original state.
(2) the second cylinder linked together with lampshade 13 moves downward, until lampshade 13 bottom surface contacts with retainer back up pad 23.Here, making both contacts one be to revise retainer back up pad 23 in horizontality, secondly reducing light impact when external light source is taken pictures on camera, making imaging more clear.
(3) camera 2 screw mandrel 6 drives and carries out up-down adjustment, and is combined with the automatic focusing function of camera 2 self, makes camera 2 be in a best focus, ensures clearer effect of taking pictures.After adjusting, camera 2 is taken pictures, and main control computer carries out image procossing to photograph afterwards, contrasts with the reference data be stored in inside storer, determines retainer 1 and is in now front or reverse side.
Here, camera selects the eigenwert differentiated to be the inner and outer diameter size of each for retainer both ends of the surface annulus carried out judging or being judged as eigenwert by the size of each for retainer end face annulus as eigenwert; Inner and outer diameter is obtained by the method for circle matching, determines the pros and cons of retainer according to the difference size of each end face inner and outer diameter; Or go out the area of each annulus according to the mathematic interpolation of inner and outer diameter, determined the pros and cons of retainer by the size of these two annulus areas.
(4) if through differentiating, retainer 1 is being in front, and namely retainer 1 faces up now.The second cylinder moving be connected with lampshade 13, lampshade is moved to extreme higher position, electromagnet energising afterwards in retainer back up pad 23 holds retainer, reducing motor 22 rotates, drive retainer back up pad 23 to rotate, retainer back up pad 23 rotates and stops to 90 degree of positions, electromagnet power-off, retainer slips into convergence slot, gets out of here from retainer outlet 10 by converging platform 16.Otherwise, if retainer is in reverse side now, after so lampshade 13 moves, retainer back up pad 23 is to counter-rotation, retainer 1 will slip into the chute of another side, like this, no matter be in front or reverse side after retainer has differentiated, from retainer outlet 10 is gone out time, be all in same direction.Here, retainer back up pad 23 is before rotation, and first by electromagnet, retainer will be held, this is to prevent retainer from sliding when retainer back up pad 23 does not go to 90 degree of positions, thus skids off and converge platform.
(5) retainer after pros and cons differentiates rolls out from retainer outlet, enters into manufacturing procedure below.
Above-described embodiment is preferred embodiment of the present invention; it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of patent of the present invention.
