Among the figure: worktable 10, work piece platform 12, camera 14, sway brace 16, runner 18, groove 20, blower 22, conveyance conduit 24, finished product basket 26.
Embodiment
Below in conjunction with description of drawings and embodiment the present invention is described in further detail:
As Fig. 1, Fig. 2 and shown in Figure 3, endoporus concentricity pick-up unit of the present invention comprises cabinet type worktable 10.Worktable 10 is provided with transportable work piece platform 12 and over against the camera 14 of work piece platform 12.Sway brace 16 by air cylinder driven is pivotally connected with worktable 10, and the free end top of sway brace 16 is provided with runner 18, and runner 18 is resisted against on the work piece platform 12.Runner 18 is driven by stepper motor (not shown).It is semicircular groove 20 that work piece platform 12 is provided with xsect, and runner 18 is resisted against on the workpiece 22 to be detected.Work piece platform 12 has and can move horizontally, and two working positions are arranged, and one is to make the take pictures position a of groove 20 over against the optical center of camera 14, and another is to make the feed entrance point b of groove 20 over against discharging opening 24.The rear of groove 20 is provided with blower 26, and its nozzle is over against groove 20, and the place ahead of groove 20 also is connected with conveyance conduit 28.Conveyance conduit 28 rear portions are over against groove 20, and its front portion can move freely, and its lower front is provided with a plurality of finished product baskets 30.
Endoporus concentricity pick-up unit of the present invention in use, work piece platform 12 moves to feed entrance point b backward, promptly groove 20 is over against the position of discharging opening 24.Pay-off is delivered to workpiece to be detected 22 on the groove 20 along discharging opening by the mode of blowing.Work piece platform 12 moves forward to the position a that takes pictures then, and promptly groove 20 is over against the position of camera 14.Be rotated down by the sway brace 16 of air cylinder driven runner 18 is resisted against on the workpiece 22 to be detected.The imaging of taking pictures of the internal diameter of 14 pairs of workpiece 22 to be detected of camera, and send into background computer and carry out the concentricity analysis.After taking a photo, by 18 rotations of step motor drive runner, runner 18 rotates by frictional force drives workpiece 22 to be detected, turns an angle, and behind 30 degree, 45 degree or 90 degree etc., continues to take pictures and analyze.Therefore can obtain the multi-angle image of this workpiece diameter, improve the precision that detects greatly.After Computer Analysis is intact, can carry out classification to workpiece 22 according to the result who analyzes, according to classification results, the front end of conveyance conduit 28 points to corresponding finished basket 30.Then, sway brace 16 upwards lifts, and unclamps workpiece 22.Blower 26 begins the operation of drying, and workpiece 22 is blown into conveyance conduit 28, and workpiece 22 is sent in the corresponding finished basket 30 along conveyance conduit 28.Thereby finish whole testings of a workpiece.
