The first field angle adjusting gear 110 is between the first strip source 106 and conveyer 100.In height, the height of the first strip source 106 is a little more than the first field angle adjusting gear 110, to avoid its light to be blocked.The height general alignment of the capsule to be measured on the first field angle adjusting gear 110 and conveyer 100.
As shown in Figure 3, the first field angle adjusting gear comprises some catoptrons, some mirror supports, each catoptron is arranged on a mirror support, and the attitude of each mirror support and position can be adjusted, the position of the catoptron of being installed to change on it and orientation; And can adjust the position of each catoptron and corresponding end-faces that orientation makes the corresponding capsule to be measured of each catoptron mirror image in corresponding catoptron over against first end imaging device 102.First end imaging device 102 be positioned at the first field angle adjusting gear 110 directly over.
Similarly, the second field angle adjusting gear has the structure similar or identical with the first field angle adjusting gear, and just the second field angle adjusting gear is placed between the second strip source 108 and conveyer 100.The second end face imaging device be positioned at described the second field angle adjusting gear directly over.Pattern recognition device is for determining the quality of the capsule detecting based on the captured image of body imaging device, first end imaging device and the second end face imaging device
Comprehensive capsule imaging device of the present utility model adopts three imaging devices sidepiece to capsule respectively, and two end faces of capsule carry out imaging, thereby realize omnibearing capsule imaging.
In addition, capsule imaging device of the present utility model can, by controlling the lighting system of Different Light, be realized the imaging to variety classes capsule.Particularly, if capsule to be measured is opaque capsule,, in imaging process, normally open the light source (the first strip source 106, the first planar light source 107, the second strip source 108 and the second planar light source 109) that the opposite end face that is useful on throws light on.If capsule to be measured is gelatin transparent capsule, in imaging process, normal the first strip source 106 and the second strip source 108 opened, and the brightness of reduction the first planar light source 107 and the second planar light source 109, thus can will capsule can be different to background; If described capsule to be measured is plant capsule,, in imaging process, close described the first planar light source and described the second planar light source, and described the first planar light source and described the second planar light source position placement background board.
Fig. 2 shows a kind of capsule detection system, this capsule detection system has adopted the comprehensive capsule imaging device shown in Fig. 1, this capsule detection system also comprises pattern recognition device, this pattern recognition device can be commercially available recognition device (image recognition chip or have single-chip microcomputer of image comparing function etc.), for image and the standard picture that each imaging device is gathered, compare, thereby whether the detected capsule of judgement meets preassigned.This system can also comprise: blanking device and tripping device, and described blanking device comprises blanking bin 201, discharge tray 202, blanking hairbrush 203, described tripping device comprises rejection device 204, good product discharging opening 205 and waste product discharging opening 206.
In addition, alternatively, capsule detection system can also comprise display 207.
When capsule detection system work of the present utility model, first by blanking bin 201, capsule is poured in discharge tray 202, blanking hairbrush 203 is set level capsule successively and unnecessary capsule brush is opened, afterwards capsule successively from discharge tray 202 to conveyer, by conveyer, bring capsule detection position into, first enter the station that body detects, by two strip sources 104 and 105, the capsule of process is carried out to polishing, 107 pairs of capsules of camera are taken.
Then, 100 pairs of capsules of conveyer are proceeded to transmit, and enter the station that first end face is detected, that is, and and between the first strip source 106 and the first planar light source 107.The end face that the first strip source 106 and the first planar light source 107 match to capsule carries out polishing, and the capsule being illuminated will, by the first field angle adjusting gear, reflex to the image of capsule end face in first end imaging device 102.First end imaging device 102 can be transported to obtained image in image recognition chip (can buy on market), processes, to determine whether the end face of the capsule detecting exists flaw or damaged.
Along with the further transmission of 100 pairs of capsules of conveyer, capsule enters the station that second end face detected, that is, and and between the second strip source 108 and the second planar light source 109.The second strip source 108 and the second planar light source 109 match to polishing of capsules, and the image of second end face of the capsule being illuminated reflexes in the second end face imaging device 103 by the second field angle adjusting gear 110.The second end face imaging device 103 can be transported to obtained image in image processor, processes, to determine whether second end face of the capsule detecting exists flaw or damaged.
In testing process, once which capsule position waste product is detection system determine, just by rejection device 204 by goods rejection, from waste product discharging opening by its output.And all do not find from good product discharging opening 205, to be sent out the capsule of flaw through detecting.
It should be noted that; the shape of all parts in accompanying drawing of the present utility model is all schematic; there is some difference not get rid of accompanying drawing and its true shape; accompanying drawing is only for principle of the present utility model is described, and the detail of parts shown in figure is the restriction to utility model protection scope not.Those skilled in the art also should be appreciated that, above-described embodiment is only also the explanation to schematic implementation of the present utility model, the restriction that not the utility model is comprised to scope.
