7. according to the implementation method of Fructus Fragariae Ananssae external sort nondestructiving grading device based on machine vision described in claim 1 to 6, its
It is characterised by: comprise the following steps:
Step 1: Fructus Fragariae Ananssae is by being manually poured in tank (21), and DC speed-regulating motor (18) drives carrier bar by synchronous pulley (17)
(6) rotate, substrate (15) be arranged on carrier bar (6) upper and with carrier bar (6) synchronous axial system, two levers being installed on substrate (15)
(16) from tank (21), Fructus Fragariae Ananssae, the distance between two levers (16) and substrate (15) are promoted along the direction that carrier bar (6) rotates
Between distance accommodate a Fructus Fragariae Ananssae the most only；
Step 2: in step 1 operation simultaneously, Fructus Fragariae Ananssae is limited to carrier bar (6) front end, tank (21) right lower quadrant by Fructus Fragariae Ananssae baffle plate (22)
Wave pump (23) of making constantly make wave, the direction of surge makes in tank (21) after flow impact tank (21) left end cell wall backward
Backflow, drives Fructus Fragariae Ananssae to contact with carrier bar (6)；
Step 3: when Fructus Fragariae Ananssae is promoted to hoisting mechanism (1) drive end, falls in conveying mechanism (2) on buffer board (26), by
Effect in gravity rolls down on conveyer belt (24)；
Step 4: by conveyer belt (24) conveying Fructus Fragariae Ananssae to visual discrimination mechanism (3) place, put in place take pictures sensor detection Fructus Fragariae Ananssae arrive
After Wei, Fructus Fragariae Ananssae is taken pictures and differentiates grade by three camera platform (28)；
Step 5: the Fructus Fragariae Ananssae differentiated continues to be delivered to sorting mechanism 4 by conveyer belt 24, after one-level sensor-triggered, monolithic
Machine carries out information processing and determines whether this Fructus Fragariae Ananssae belongs to one-level, if it is, this Fructus Fragariae Ananssae is screened in one-level electric magnet action, if not
It is that Fructus Fragariae Ananssae continues, by tape transport to two grade screening, to trigger diode sensor, if it is, two-stage electromagnetic ferrum action, if
Not, continue on at three level screen, trigger three grades of sensors, three grades of electric magnet actions.
The implementation method of Fructus Fragariae Ananssae external sort nondestructiving grading device based on machine vision the most according to claim 7: step 1
Described in hoisting mechanism (1) spacing to Fructus Fragariae Ananssae by Fructus Fragariae Ananssae baffle plate (22), described in make wave pump (23) formed reverse flow, and coordinate institute
State the most single of carrier bar (6) and promote Fructus Fragariae Ananssae；Three camera vision platforms (28) are used to carry out lossless differentiation Fructus Fragariae Ananssae etc. described in step 4
Level；Wherein, visual discrimination mechanism described in conveying mechanism (2), step 4 described in the hoisting mechanism in step 1 (1), step 3
And sorting mechanism described in step 5 (4) is controlled by described controlling organization (3).
