The detection device for foreign matter that is used for automatic lamp-checking machine
Technical field
The utility model is mainly concerned with the pharmaceutical machine apparatus field, refers in particular to a kind of detection device for foreign matter that is used for automatic lamp-checking machine.
Background technology
In the pharmaceutical machine apparatus field, lamp inspection machine is that a kind of optical imaging, computing machine of utilizing compares principle to image, and packages for liquid drug quality is carried out the seriation specialized equipment that automatic intelligent detects.The view data that Computer Analysis collects, liquid towards drug quality judge, reach a conclusion and command lamp inspection machine on the rejecting oscillating arm mechanisms underproof medicine bottle is rejected.
In the existing lamp inspection machine, packaged liquid medicine (such as the ampoule bottle that installs soup etc.) can be sent to successively on the lamp inspection dish, detection (such as white piece, stain, fiber and glass chip or the like) finished to foreign matter in institute's splendid attire soup in the bottle.In this process, not only to allow bottle rotate along with lamp inspection dish, also need to allow bottle produce brake hard after the high speed rotation.
Because in the foreign matter testing process, for convenience of observation to foreign matter, shilling bottle produces the high speed rotation before detecting, the centrifugal force that produces by high speed rotating throws up the foreign matter in the bottle, make medicine bottle suddenly stop again, so just can finish and form that bottle stops when taking pictures and duty that soup rotates, thereby improve the accuracy of detection of image collecting device at image collecting device.
The deficiency that existing structure exists just is: 1, the layout density owing to the axis of rotation on the lamp inspection dish is very big, the spacing of the adjacent axis of rotation is very short, when driving belt when the axis of rotation belt wheel, because axis of rotation belt wheel scale error, so the efficient of common transmission is bad, poor stability often occurs the adjacent axis of rotation easily and rotates inconsistent situation, can't guarantee accuracy of detection; For fear of above-mentioned phenomenon, adopted adjacent axis of rotation belt wheel staggered floor assembling, strengthened with the interval between the layer belt wheel, reduced belt wheel by built on stilts risk.2, in testing process, when image collecting device detected adjacent two bottles to be detected, the speed when two bottles to be detected arrive tested measuring point was inconsistent, and it is inconsistent to cause soup in the medicine bottle to rotate, thereby influences accuracy of detection; 3, the existing structure arrestment mechanism that generally adopts " swing arm " formula carries out one side brake to the bottle of high speed rotating.Because the time of braking is short more, the damping force that can produce is just big more, and foreign matter just can move and better be caught by image collecting device in the soup.And existing swing arm arrestment mechanism can't make the bottle of high speed rotating stop in the shortest time.In addition, " swing arm " formula arrestment mechanism is in a side axis of rotation that drives the bottle rotation to be braked, belong to one side brake, under the impulse force influence, make bottle can't keep equilibrium state easily, off-centre or motion unstability, damping force is little, effect not as bilateral braking, brings influence to image acquisition certainly.
