Fig. 1 is the main TV structure schematic diagram according to foreign matter imaging device at the bottom of the bottle of an embodiment of the present utility model;
Fig. 2 is the main TV structure schematic diagram according to foreign matter imaging device at the bottom of the bottle of another embodiment of the present utility model;
Fig. 3 is the perspective view of foreign matter imaging device at the bottom of bottle embodiment illustrated in fig. 2.
Embodiment
As shown in Figure 1, foreign matter imaging device at the bottom of the bottle in the present embodiment comprises bottle bottom illuminating light source 1, imaging device 2, image collecting device 3.In the present embodiment, two bottle bottom illuminating light sources 1 are adopted.Two bottle bottom illuminating light sources 1 are placed in the both sides of bottle to be imaged (being positioned at inspection positions) respectively, and near the bottom being positioned at bottle 4 to be imaged.The light-emitting area of two bottle bottom illuminating light sources 1 is all at the bottom of the bottle of bottle 4 to be imaged.More specifically, the light emission direction of two bottle bottom illuminating light sources 1 is perpendicular to the side of bottle 4 to be imaged, just be treated as at the bottom of the bottle as bottle 4 and irradiating, to avoid illuminating bottle 4 to be imaged part except at the bottom of bottle, the liquid especially carried in bottle and bubble wherein thereof as far as possible.
Certainly, do not get rid of the bottle bottom illuminating light source adopting other numbers, such as, adopt four bottle bottom illuminating light sources, four bottle bottom illuminating light sources are equally spaced arranged in around the sidepiece of bottle to be imaged.
Imaging device 2 is placed in the below of bottle 4 to be imaged, at the bottom of the bottle of bottle 4 to be imaged, so that the image at the bottom of collecting bottle.Imaging device 2 can adopt conventional CCD camera or other imaging devices.Imaging device 2, when image acquisition, mainly focuses on the bottle bottom part of bottle 4 to be imaged.Imaging device in the utility model can also comprise some stationary installations, for imaging device 2 being fixed on the bottom of bottle to be imaged, being fixed on by bottle bottom illuminating light source 1 and detecting around position.
Image collecting device 3 is connected with imaging device 2, for receiving the image that imaging device 2 collects from imaging device 2.Image collecting device preferably adopts and image pick-up card is housed.
In the preferred implementation of one, bottle bottom illuminating light source is strip source, and the length direction of strip source is parallel to place plane at the bottom of the bottle of bottle to be imaged.
More preferably, at the bottom of bottle, foreign matter imaging device can also comprise conveying device, and described conveying device carries bottle to be imaged, and the length direction of strip source is parallel to the direction of motion of described conveying device.In this implementation, some bottles to be imaged 4 can be placed in described conveying device equally spacedly.Conveying device at the uniform velocity or is stepwise advanced, bottle 4 to be imaged is driven to advance, an each inspection positions bottle 4 to be imaged being transported to bottle bottom illuminating light source and being irradiated to, correspondingly, imaging device is in response to the arrival of each bottle to be imaged, the image of this bottle to be imaged is taken, then, image acquisition device image.Pick-up unit can also be utilized manually or automatically to judge whether the bottom of bottle to be imaged exists foreign matter based on taken image.
If adopt the mode of comparing with standard picture to carry out the judgement of foreign matter, then, before formally detecting, need acquisition module image in advance.Specifically, first can open conveying device, one or several standard bottles are passed at the uniform velocity, reposefully and detects position, imaging device gathers the image at the bottom of bottle of standard bottle, obtains standard form.Then, recycling pick-up unit is treated as and detects as bottle.Pick-up unit can adopt image recognition chip.
Fig. 2 is the main TV structure schematic diagram according to foreign matter imaging device at the bottom of the bottle of another embodiment of the present utility model.As shown in Figure 2, in the present embodiment, at the bottom of bottle, foreign matter imaging device comprises: bottle bottom illuminating light source 1, imaging device 2, image collecting device 3 and shadow shield 5.
In the present embodiment, bottle bottom illuminating light source 1, imaging device 2 and image collecting device 3 adopt and structure similar in above-described embodiment, just with the addition of a pair shadow shield 5.
Why adding shadow shield 5 is because present inventor recognizes, in the imaging of foreign matter or testing process at the bottom of to bottle, only have the irradiation at the bottom of to bottle can promote imaging to foreign matter or detection, not only can not promote the imaging of foreign matter to the additional radiation of other parts of bottle or detect and can bring certain interference on the contrary, reducing accuracy.
As shown in Figures 2 and 3, shadow shield 5 is close to the coboundary of bottle bottom illuminating light source 1, and stretches out from the top of lighting source towards bottle 4 to be imaged.Each shadow shield 5 can be bolted on corresponding bottle bottom illuminating light source 1 top, or is bonded in corresponding bottle bottom illuminating light source 1 top by stickum.
By shadow shield 5, the light beam sent from bottle bottom illuminating light source 1 can be made only to be irradiated to the bottle bottom part of bottle to be imaged, and not to be irradiated to body, avoid the reflected light of the liquid in body or bottle to bring interference to detection.
Certainly, more preferably, described bottle bottom illuminating light source 1 is high directionality light source, such as, and the LED array etc. that beam divergence angle is very little.
In addition, in order to better the light that lighting source sends is gathered bottle to be imaged bottle at the bottom of, at the bottom of bottle in the present embodiment, foreign matter imaging device can also comprise the condenser lens of strip, condenser lens can be placed between bottle bottom illuminating light source 1 and bottle to be imaged 4, be parallel to bottle bottom illuminating light source 1 to place, converge at the bottom of the bottle of bottle to be imaged with the irradiation light that light source is sent.
In addition, because the device in the present embodiment is generally used in production line, the light angle of light source and the position of camera are subject to the restriction of existing machinery structure in production line, therefore, in a particular application, suitably can adjust the position of light source, to adapt to site environment.
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 itself and its true shape; accompanying drawing is only for being described principle of the present utility model, and the detail of parts shown in figure is not the restriction to utility model protection scope.Those skilled in the art also should be appreciated that, above-described embodiment is also only the explanation to exemplary implementation of the present utility model, not the utility model are comprised to the restriction of scope.
