Description
Technical field
This utility model belongs to Product checking field, particularly relates to column shape container inner wall defect stravismus automatic detection device.
Background technology
In column shape container production process, container inner wall there will be some defects unavoidably, such as foreign body, greasy dirt, scratches, becomes
Shape etc..The most direct and the to be filled thing of some foreign body being attached on inwall contacts, and it will result directly in food safety accident or matter
Amount accident, affects properties of product and corporate reputation.
Column shape container is usually and is made up of container bottom and chamber wall, and before not having fill, one end of container is unlimited,
For the column shape container of opacity, the defect wanting to find on container inner wall is it is necessary to observe from one end of container open
And detection.
Detection method generally comprises: 1. manual detection: manual detection is one of traditional detection method, but produces linear speed
Height, manual detection efficiency is low, of poor quality.Manual detection is difficulty with the full inspection to all products.2. machine detection: along with vision
The development of detection technique, the method having occurred in that Machine Vision Detection.Machine Vision Detection is relative to manual detection, detection speed
Spend to have had and be obviously improved.
But the equipment of column shape container inner wall defect detection the most both at home and abroad all has a common ground, it is simply that camera is positioned on container
Side is perpendicular to container bottom capture straight down detection, the namely axis of camera and the dead in line (0 of detected column shape container
Degree) or angle less than 15 degree, referred to herein as look at straight.This kind of direct gaze detection method directly contributes container inner wall image and is compressed, special
Be not from camera distance more away from container inner wall compress the most serious, this has just severely impacted accuracy of detection, causes a lot of appearance
Device internal flaw cannot detect.
Particular with the container of rolling muscle, camera axis and container axis coincidence or the detection less than 15 degree is also used to set
Standby, container inner wall bossing will be formed and block and affect capture, causes some regions cannot imaging, it is impossible to imaging is the most not
The defect of respective regions can be detected.
Utility model content
This utility model purpose is to provide for a kind of simple in construction, the column shape container inner wall defect stravismus that Detection results is good
Automatic detection device.
In order to realize purpose this utility model by the following technical solutions: a kind of column shape container inner wall defect stravismus inspection automatically
Surveying device, including automatic carriage and detection device, described automatic carriage includes conveyer belt and holds for detecting column
The position sensor of device position, described detection device includes at least two camera, camera lens, LED light source, graphics processing unit, picks
Except control unit, described camera is distributed ringwise relative to the axis of column shape container, the axis of described camera all with column shape container
Axis between have more than 15 degree less than 75 degree of angles；Described LED light source is arranged on below described camera lens, described LED
Light source is ring-type LED light strip；Described camera and described graphics processing unit are connected by communication, described graphics processing unit and described
Rejecting control unit is connected by communication, and rejects control unit and includes rejecting actuator, and it is controllable flexible for rejecting actuator
Bar or compressed air venthole.
Preferably, described column shape container includes cylindrical container and triangular form column shape container and square column shape container.
Preferably, described camera is 2, the axis of described 2 cameras all become with the axis of column shape container 15 degree to 75 it
Between angle.
Preferably, described camera is 3, the axis of described 3 cameras all become with the axis of column shape container 15 degree to 75 it
Between angle.
Preferably, described camera is 4, the axis of described 4 cameras all become with the axis of column shape container 15 degree to 75 it
Between angle.
Preferably, described camera is 5, the axis of described 5 cameras all become with the axis of column shape container 15 degree to 75 it
Between angle.
Preferably, described camera is 6, the axis of described 6 cameras all become with the axis of column shape container 15 degree to 75 it
Between angle.
This column shape container inner wall defect detection device, discloses a kind of camera axis and testing container axis has a clamp
The detection device at angle, is angle and the method imitating manual observation column shape container, i.e. by the method for stravismus, the figure of container inner wall
As flattening in image-forming component as best one can, container inner wall compression of images problem can be reduced, be effectively improved accuracy of detection, especially
Being to improve away from the accuracy of detection of inwall at camera exponentially, also solving rear area at rolling muscle container projections cannot become
The problem of picture.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the technical scheme that this use is novel is further elaborated.
The embodiment of a kind of column shape container inner wall defect stravismus automatic detection device as shown in Figures 1 and 2, including certainly
Dynamic conveying arrangement and detection device, described automatic carriage includes conveyer belt 1 and for detecting the position of column shape container position
Sensor 3, position sensor 3 includes emitter and the receptor being respectively fixed on conveyer belt both sides, when column shape container 7 move to by
During detection position, column shape container, between described emitter and receptor, blocks the letter between told emitter and receptor
