Description
Technical field
The present invention relates to foreign body intelligence detection methods in a kind of oil drum bucket.
Background technology
Oil packaging has plastic barrel and metal bucket, whether which kind of container, will be checked before the use, to have prevented
Foreign matter and water are remained in bucket.Foreign matter in bucket is small to the quality that can influence oil product, greatly to use in the process by iron filings residue
It is filled into equipment, makes equipment gear failure, cause equipment damage indirectly, more there is even meeting crisis personal safety, it can be seen that,
Detection before packing container use is particularly important.Current each Oil Production packaging plant is detected using eye-observation,
Since bung hole diameter is small, and bucket depth degree is larger, and human eye is caused to be present with omission in detection process.
The content of the invention
To solve the above-mentioned problems, the present invention provide in a kind of oil drum bucket foreign body intelligence detection device and on this basis to
Output detection method.By the present invention in that being taken pictures with industrial camera, the method for computer analysis whether there is foreign matter to distinguish in bucket.
This apparatus structure is simple to operation, but more can accurately carry out foreign bodies detection in bucket, reduces artificial detection time and error rate,
Improve Detection accuracy.The present invention takes following technical scheme to realize：
Foreign body intelligence detection method in a kind of oil drum bucket, used device include testing agency's main body frame, whirler
Structure, positioning baffle, PLC, main body of taking pictures, elevating mechanism and computer, oil drum are placed in the top of rotating mechanism, which is characterized in that
Elevating mechanism is fixed on the top of main body frame, and the main body of taking pictures is vertically fixed on elevating mechanism, take pictures master for strip
The fixed position of body determines according to the distance between oil drum bung hole and rotating mechanism center, and mechanism takes pictures and is fixed with four in main body
A camera model：2 bucket inner wall detection camera models, a positioning camera module and the outer label scanning camera module of 1 bucket,
In, 2 bucket inner wall detection camera models are fixed on the different position of the lateral lower part for main body of taking pictures, and positioning camera module is fixed on
The bottom for main body of taking pictures, the outer label scanning camera of bucket fix body top of taking pictures.Detection method is as follows：
Oil drum is sent to main body frame position, is stopped when reaching check position by positioning baffle, and rotating mechanism is by oil
Bucket is raised to setting height and rotates oil drum, and oil drum rotates the positioning camera being located at simultaneously immediately below agent structure of taking pictures to oil drum
It takes pictures above, positioning camera sends photo to computer and analyzes, and analysis result is fed back to PLC, PLC by computer
Oil drum mouth position is determined by analysis result, rotating mechanism stops rotating after the completion of positioning, and main body mechanism of taking pictures passes through elevator
Structure is stretched into inside oil drum, is reached after specifying stroke, and the tag scan camera outside PLC triggering oil drums is to the mark above oil drum
Label carry out the storage ID that takes pictures, and excess-three camera sends photo to computer and analyze to taking pictures in bucket, so as to
It alarms defective products.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.Fig. 1 (a) and (b) are total layout of the present invention
The location diagram of figure and each component, Fig. 2 are agent structure form figure of taking pictures.
Description of the drawings：1st, testing agency's main body frame 2, rotating mechanism 3, positioning baffle 4, console 5, tag scan
Camera 6, bucket wall detection camera 7, positioning camera 8, conveyer belt
Specific embodiment
The specific implementation method of the present invention is further described below in conjunction with description of the drawings.
Manually by oil barrel conveyor to conveyer belt 8, oil drum is sent at testing agency's main body frame 1 by conveyer belt 8.Work as oil
Bucket illustrates that oil drum has arrived at test position when being contacted with positioning baffle 3, and the cylinder below rotating mechanism 2 is by whirler at this time
Structure 2 and oil drum thereon lift certain altitude, and rotating mechanism 2 then drives oil drum to rotate, while is located at the master that takes pictures above oil drum
Positioning camera 7 immediately below body above oil drum to taking pictures, and the computer that photo is sent in console 4 is analyzed,
Analysis result sends PLC to, after PLC determines the position of oil drum mouth according to analysis result, then signal is feedbacked makes whirler
Structure 2 stops rotating, and after rotating mechanism 2 stops rotating, positioning camera 7 does secondary positioning to carrying out taking pictures above oil drum again, determines
Directly over oil drum mouth, detecting the elevating mechanism on main body frame at this time will take pictures in main body mechanism feeding bucket camera, reach row
After journey 100mm, tag scan camera 5 is taken pictures and is preserved to label above oil drum, and the picture as this oil drum stores ID, together
When 2 bucket inner walls detection cameras 6 and positioning camera 7 respectively oil drum inner wall and oil drum bottom surface take pictures for the first time, work as stroke
It is taken pictures for the second time when reaching 240mm, and the result that will take pictures is sent to PC and analyzes, and can lead to if finding foreign matter or water mark
It crosses alarm lamp and provides prompting, subsequent processing is entered if not alarming.
The flow positioned twice is as follows：PLC controls camera is taken pictures after oil drum movement in place, and PC is analyzed after receiving picture
The central point r1 of bung and bung hole central point r2 is found respectively, then using r1 as default coordinate origin, passes through the relation of r1 and r2
It calculates the angle ∠ 1. for needing to rotate and is sent to PLC, PLC control motors are rotated.It chooses to install and stops afterwards in place, complete the
One-time positioning.PLC controls camera is taken pictures after the completion of the first positioning, is carried out second and is positioned, positioning principle is identical with first time.
Foreign bodies detection inside oil drum can be realized by above-mentioned structure.
