In the present embodiment, camera 1 support is supported on main platform 4, an assemble mechanism 7 is placed in main platform 4 centre position, the half-finished material storage dish 3 after an assembling is placed on right side, a robot 5 (such as six-joint robot) is placed in main platform 4 front portion, and robot head is a star-wheel jaw 23.Be connected with mechanical arm connection between mechanical arm and vision-based detection intelligent controller, camera 1 is connected with vision-based detection intelligent controller by connection.Under isolator star-wheel being optionally placed on the region that camera can be irradiated to, dynamic scan is carried out through vision-based detection CCD, image transmitting scanning obtained is to vision-based detection intelligent controller, and vision-based detection intelligent controller, by image processing algorithm, draws the level angle of star-wheel.Computer is again by mechanical arm connection, drift angle numerical value is passed to robot, robot is grabbed by hand and captures star-wheel, the 6th axle is carried out deflecting the star-wheel deflection angle that video camera detects subsequently by automated procedures, star-wheel is grabbed the outlet to assemble mechanism 2 times alignment springs rollers simultaneously, after completing assembling, the star-wheel after assembling is put in material storage dish by star-wheel jaw
As Fig. 2, under star-wheel is placed on camera with random position, utilize OPENCV vision storehouse, first detect the central coordinate of circle (x of star-wheel
0, y
0), then detect the tooth profile inside star-wheel, extract the pixel coordinate of each point of profile
calculate again point on profile and central coordinate of circle point square distance and, D=(x
i-x
0)
2+ (y
i-y
0)
2, obtain the minimum of a value D of D
min, and obtain the pixel coordinate value on corresponding profile
so they are brought into formula
star-wheel deflection angle γ can be obtained, thus composition one group of discernible coordinate points (x of robot
0, y
0, h, 0,0, γ), h is the actual height of isolator star-wheel.
The assembling device of the present embodiment comprises a main platform 4, camera 1 is had at the left frame of main platform 4, isolator star-wheel 6 to be assembled is placed under camera, main body assembler 2 is had in the centre of workbench 4, be placed with accumulator 3 on the right side of workbench, place six-joint robot 5 in the front of workbench.Described main body assembler has main assembly support 7, is divided into three lattice generally.Have the second motor 8 in topmost portion, centre is fixed with eccentric mechanism 9, by driven by motor.Back-moving spring 10 is placed between jacking block 11 and support.As Fig. 5, turn core 15 and be fixed in the bottom of main assembly support, it is driven by motor 8.Be fixed with spring material loading track 14 in the bottom front portion of support, bottom top is fixed with pusher guide rail.Described pusher is as Fig. 4, and it is by pusher jacking block 16, crank connecting link 18, and drive motors 19 forms.Pusher jacking block has gathering sill 17.Manipulator jaw 23 is connected to the terminal shaft of six-joint robot.
Concrete assembling process is as follows:
(1) isolator star-wheel 6 to be assembled is placed on the surveyed area under camera 1;
(2) computer obtains the star-wheel original image information that camera obtains, and carries out image procossing, calculates centre coordinate and the star-wheel drift angle (x of star-wheel
0, y
0, h, 0,0, γ);
(3) coordinate information is transferred to robot 5 by connection by computer, and mechanical arm captures star-wheel 6, and mechanical arm terminal shaft driving mechanical hand jaw 23 rotates subsequently, and the groove of star-wheel is alignd with the groove 22 turning core 15.
(4) while mechanical arm captures, spring carries out material loading along spring loading guide 14, roller falls from the hole kicker baffle 12, then pushing material component pushes spring and roller and turns in core 15, and the second motor 8 rotates 72 °, repeats material loading action 5 times, until turn core groove to be filled position, first motor 24 is with movable eccentric wheel to rotate, and is pushed away for 11 times by jacking block, spring and ball is pushed in the groove of star-wheel 6.
(5) complete assembling action, the star-wheel after assembling is put in material storage dish 3 by mechanical arm.
