Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 to 4, a kind of screw detecting machine of the present invention comprises frame 10, frame 10 is horizontally disposed with the index dial 12 of a circle, and frame 10 is arranged with the driving mechanism 14 driving index dial 12 to rotate, be motor in the present embodiment, other common driving mechanisms are also passable certainly.The groove 16 of the multiple accommodation screw of edge spaced set of index dial 12, groove 16 is extended to index dial 12 center by index dial 12 edge.
Frame 10 side or frame 10 also arrange a feed mechanism 18, screw is delivered to successively in groove 16; Feed mechanism 18 comprises a vibrating disc 20, and the outlet of vibrating disc 20 connects an inclined ramp 22, and the other end of slideway 22 connects index dial 12, arranges a chute run through 24 along its length in the middle of slideway 22.During use, screw enters chute 24 from the shock effect of vibrating disc 20, and the head of screw is just in time stuck on chute 24, then slides along chute 24, enters into groove 16 successively; Now, the head of screw is also just in time stuck in the edge of groove 16, thus realizes orderly feed.
Along index dial 12 rotation direction, be disposed with one first detection camera 26, substandard products cutting agency 28 and certified products cutting agency 30; First detection camera 26 level is just to the groove 16 on index dial 12, so that the screw of front shooting groove 16;
Substandard products cutting agency 28 is for collecting the screw substandard products detecting and obtain, and certified products cutting agency 30 is for collecting the screw certified products detecting and obtain;
One main control system (not shown), main control system connects certified products cutting agency 30, substandard products cutting agency 28, first checkout gear and the first detection camera 26.
Like this, during its work, first taken pictures by the first detection camera 26, certainly, correspondence position can arrange range sensor (not shown), to detect this position with or without screw.Picture transmission, to main control system, carries out image procossing and analysis by main control system, obtains the detection architecture of relative dimensions, thus judges that this screw is certified products or substandard products.Substandard products, through substandard products cutting agency 28 place, can be taken away by substandard products cutting agency 28, and collect.Screw on all the other index dials 12 arrives certified products cutting agency 30 place, all to be taken off from index dial 12 by certified products cutting agency 30 and collects.
As shown in Figure 3, the substandard products cutting agency 28 of the first embodiment comprises the blowpipe 32 of a connection high pressure gas, and blowpipe 32 is just to the groove 16 on one division dish 12, and blowpipe 32 exports just to a tubaeform rewinding mouth 34.Screw is blown in rewinding mouth 34, to collect from index dial 12.
As shown in Figure 4, the substandard products cutting agency 28 of the second embodiment comprises L-shaped discharge driving lever 36 and the cylinder 38 driving discharge driving lever 36 to move horizontally.By the movement of cylinder 38, screw is dialled from index dial 12.It better can solve the blanking of larger, heavier screw.
Certified products cutting agency 30 is a driving lever 40 being horizontally set on above index dial 12, on the horizontal screw on index dial 12 of driving lever 40 level, driving lever 30 is arranged one just to the cambered surface 42 of screw.Like this, the screw all to this all can move along cambered surface, thus comes off from index dial 12.
Further, it is vertical just to the screw on index dial 12 that one second detection camera 44, second detection camera 44 can also be set, thus shooting screw head, to detect the pit for placing screws cutter of screw head, comprise the position and size etc. of pit.In order to detect the degree of depth of this pit further, frame 10 is also arranged a hole depth checkout gear 46.
As shown in Figure 5, hole depth checkout gear comprises a fixed block 47, fixed block 47 is arranged a connecting rod 48.Fixed block 47 connects cylinder (not shown), and the free end of connecting rod 48 is threaded a probe sleeve 50.Probe sleeve 50 comprises inner core 52 and urceolus 54, and urceolus 54 can be socketed on inner core 52 vertically movably, and inner core 52 is threaded on connecting rod 48, the end face of urceolus 54 is provided with the probe 56 of taper.Connecting rod 48 overlaps a stage clip 58, stage clip 58 one end is resisted against on fixed block 47, and the other end is resisted against on urceolus 54.
During use, air cylinder driven connecting rod 48 drives probe 56 to press down, and is deep in the pit of screw, until be resisted against pit bottom, stage clip 58 plays the effect of buffering.
As shown in Figure 6, by shooting probe 56 against the photo of the pit 60 of screw 58, then detect photo, the degree of depth that probe 56 is deep can be obtained, be i.e. the degree of depth of pit.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
