Detailed description of the invention
In order more specifically to describe the present invention, below in conjunction with the drawings and the specific embodiments, a kind of Novel steel ball for vision-based detection of the present invention is launched to be elaborated with sorting unit.
As depicted in figs. 1 and 2, a kind of Novel steel ball for vision-based detection launches to comprise feed mechanism 14, material loading passage 13 with sorting unit, detect groove 1, feed shelter 2, feeding rotating shaft 7, test chamber 10, detection light source 11, video camera 12, fan-shaped back-up block 15, eccentric wheel 8, slide block 9, separator plate 3, sorting rotating shaft 4 and tapping channel 6.
Feed mechanism 14 is connected with the feed shelter 2 being arranged in detection groove 1 by material loading passage 13, according to the upper ball frequency of setting, steel ball conveying to be checked is delivered on feed shelter 2.Feed shelter 2 is made for milky light transmissive material, is uniformly distributed some quantity test chamber 10 on its circumference.Described test chamber 10 is for connecting the manhole of feed shelter 2 upper and lower surfaces, and its degree of depth must be greater than steel ball size.Feed shelter 2 is rotated counterclockwise in process, drives steel ball in test chamber 10 along circular motion, accepts vision-based detection in position to be checked, realizes sorting going out ball position according to detecting feedback information.
Feed shelter 2 belows are provided with fan-shaped back-up block 15, slide block 9 and separator plate 3, and the adjacent face of fan-shaped back-up block 15, slide block 9 and separator plate 3 fits tightly, and contact gap is as far as possible little, has both ensured the freely-movable of slide block 9 and separator plate 3, does not make again steel ball to be checked block.The upper surface flush of fan-shaped back-up block 15, slide block 9 and separator plate 3, and fit with the lower surface of feed shelter 2.
Separator plate 3 is provided with certified products spherical cavity 5 and substandard products spherical cavity 16, and separator plate 3, by controlling rotary course, realize certified products spherical cavity 5 and align with certified products tapping channel, or substandard products spherical cavity 16 aligns with substandard products tapping channel.The size of certified products spherical cavity 5 and substandard products spherical cavity 16 will guarantee freely to pass through 1 goal standard steel ball, and tapping channel 6 passes from detecting groove 1 bottom.
Slide block 9 is fixed on and is detected groove 1 bottom by guide rail, and eccentric wheel 8 is coaxially connected with feeding rotating shaft 7, and the band movable slider 9 that rotatablely moves of eccentric wheel 8 is done translational motion.
Feed shelter 2 is connected realization and rotatablely moves with feeding motor by rotating shaft 7.When feed shelter 2 is rotated counterclockwise, steel ball to be checked is subject to tangential forces; Feed shelter 2 is done translational motion with the synchronous rotary Sports band movable slider 9 of eccentric wheel 8, and steel ball to be checked is subject to immixture power tangential and radially.The present invention, by the coordination control with slide block 9 to feed shelter 2, realizes steel ball surface to be checked and is fully presented in camera coverage.When steel ball to be checked has characterized 3 developed surfaces under tangential effect during in position 20 to be checked, position to be checked 21 and position 22 to be checked; When steel ball to be checked has characterized 3 developed surfaces under immixture during in position 17 to be checked, position to be checked 18 and position 19 to be checked.The video camera 12 that top, position to be checked arranges is taken and is comprised that 6 steel ball states on position 20 to be checked, position to be checked 21, position to be checked 22 and position to be checked 17, position to be checked 18, position to be checked 19 are 1 width image, utilize corresponding image processing algorithm to judge whether steel ball to be checked exists defect, in algorithm, be provided with mnemon, the final detected state of same steel ball is by 6 locational state synthetic determinations to be checked in feed shelter 2 rotary courses.
Separator plate 3 is realized and being rotatablely moved with sorting motor by sorting rotating shaft 4, and certified products spherical cavity 5 and substandard products spherical cavity 16 are evenly set on separator plate 3, certified products spherical cavity 5 and substandard products spherical cavity 16 cross-over configuration, and substandard products spherical cavity 16 is in the outer rim of separator plate 3.In actual product detects, product percent of pass, generally much larger than 50%, is therefore controlled certified products spherical cavity 5 and is alignd with certified products tapping channel under default setting.In feed shelter 2 rotary courses, drive certified products steel ball automatically to fall into certified products spherical cavity 5 and certified products tapping channel, lead to certified products storehouse.When discovery is current, in the time going out ball (wait going out ball position 23) for substandard products, separator plate 3 rotates, and controls substandard products spherical cavity 16 and aligns with substandard products tapping channel, and substandard products steel ball falls into substandard products spherical cavity 16 and substandard products tapping channel, leads to substandard products storehouse; After substandard products steel ball drops, separator plate 3 continues rotation, reverts to default setting, waits for the processing of next steel ball.
The thickness of separator plate 3 is thin as far as possible, as long as ensure the mechanical strength of separator plate 3.The thickness of separator plate 3 has determined the stand-by period that steel ball drops in process, and the state (go out certified products state with go out substandard products state) that therefore goes out ball passage is significantly less than the response time of traditional door-controlled type Chu Qiu mechanism switching time.
Feed shelter 2, fan-shaped back-up block 15, slide block 9, separator plate 3 and steel ball to be checked are all immersed in and detect in the interior detection liquid of groove 1, and detection liquid is colourless transparent liquid, is kerosene or aqueous rust preventive, and the liquid level that detects liquid will be higher than the upper surface of feed shelter 2.The present invention's feed mechanism 14 used, material loading passage 13, feed shelter 2, fan-shaped back-up block 15, slide block 9, separator plate 3, tapping channel 6 are all made with organic material, to prevent the damage to steel ball surface to be checked in testing process.
In practical application, for improving the reciprocating frequency of slide block 9, gear iso-variable velocity mechanism can be set between eccentric wheel 8 and feeding rotating shaft 7; For improving detection speed, many group detection light source 11 and video camera 12 can be set, carry out the quality testing of many group steel balls simultaneously; For improving accuracy in detection, can increase the width of slide block 9, for example each video camera detects 6 deployed conditions of steel ball, and 2 video cameras just can detect 12 deployed conditions of steel ball, ensure steel ball surface fully representing under machine vision.
