Description

It is a kind of to be used for engine, the online visible detection method of gearbox surface coating
Technical field
The invention belongs to field of automobile, it is more particularly to a kind of for engine, gearbox surface coating Line visible detection method.
Background technology
Current automobile engine, gearbox body surface coating in actually laminating, due to robot coating etc. is uneven can It can cause disconnected glue or tree lace skew.After the completion of so assembling, engine, gearbox permeability feelings can be caused in actual applications The generation of condition, this has had a strong impact on car mass, and larger hidden danger is will also result in for automotive safety, produces serious consequence.
Under normal circumstances, usually robot or manual gluing, then arrange personnel to carry out Preliminary detection again.It is last whole Check.But above-mentioned situation, have disadvantages that and not enough:
First, it is necessary to which at least 2 employee's detections, personnel cost is higher in whole detection process.
2nd, in whole process, if many colloid tracks of cylinder surface or width change, when personnel are difficult long Between can with the naked eye differentiate.This is higher to personnel requirement, and operator's door detects by an unaided eye for a long time, easily produces fatigue, easily allows Some underproof product outflows, cause quality problems.
Once the 3, substandard product flows out, artificial after cylinder body laminating is difficult to be rechecked, and directly will result in quality and asks Topic, quite seriously.
The content of the invention
Present invention offer is a kind of to be used for the online visible detection method of engine or gearbox surface coating.
It is a kind of to be used for the online visible detection method of engine or gearbox surface coating, comprise the following steps:
A1 is static in place by cylinder body to be detected;
Positioning starting signal is sent to IMAQ camera by A2, external equipment;
A3, IMAQ camera selects number of times of taking pictures according to cylinder size and tree lace length;
A4, is analyzed every image, and the Qualification for tree lace of taking pictures every time is searched using InspectEdge instruments;
A5, internal system is calculated, and final result is sent into robot;
A6, robot chooses whether gluing of letting pass or stop according to camera result;
A7, waits next time that cylinder body is in place.
Before normal workflow is implemented, also including step:
B1, camera and robot communication and point selection of taking pictures, i.e.,
Need the cylinder body of detection to be placed under camera, robot according to first pre- gluing one time of actual tree lace track,
Camera is required according to the accuracy of detection of actual tree lace, selects suitable field range,
The requirement of camera fields of view is installed by robot, and setting is taken pictures a little, and robot takes pictures at taking pictures to camera,
The signal that the communication needs of robot and camera set and alarm, interrupt, in order in actual production, occur to answer Handled in the case of urgency;
B2, camera, which are repeatedly taken pictures, to collect, i.e.,
Camera is taken according to actual tree lace after the completion of figure, and carrying out camera according to number of times of taking pictures takes pictures processing,
Camera is detected that, when counting proceeds to a certain number, camera enables to enable each section of program using counting Corresponding program segment is detected in program,
The corresponding instrument of each program segment is identical, but arrange parameter and threshold value can be different,
Last camera completes signal after the completion of counting to robot, and empties count content, is easy to next cylinder body again Count.Camera by the summary repeatedly taken pictures, judge and send to robot.
The present invention is repeatedly taken pictures using single camera, and each camera fields of view scope is smaller.And follow robot coating rail Mark is moved together.Detection of taking pictures is tracked to the colloid above just applied during gluing, by the total of detection of repeatedly taking pictures As a result it is sent to external equipment.Repeatedly taken pictures by single camera, take pictures and detect all individually progress every time.Finally result is converged Always, and the image integration display that will repeatedly take pictures is for manually checking.
Effective effect of the present invention includes:
First, since gluing, terminate directly detection to gluing and complete, 5 seconds are not required to altogether, without extra increase inspection Measurement equipment, letter is answered conveniently.More than 20 times are improved with respect to man efficiency.
2nd, can the annual continuous throughout the twenty-four hour24 of whole day 24.
3rd, disposable input, correspondingly reduces by 3 costs of labor.
4th, human users are not needed, the accidental error of personnel's detection are greatly reduced, it is ensured that the reliability of detection.
5th, the type of compatible different model, while only needing addition program, it is not necessary to increase mechanical structure.
6th, just gluing completes to carry out vision-based detection, it is to avoid subsequent work stations and other interference, Detection results are more accurate Really.
Brief description of the drawings
Fig. 1 is online test method flow chart of the present invention.
Embodiment
As shown in figure 1, the be used for engine, the online visible detection method of gearbox surface coating of the present invention include:
1. product is static in place
2. positioning starting signal is sent to IMAQ camera by external equipment
3. camera is taken pictures according to cylinder size and the selection of tree lace length
4. camera is analyzed every image, the qualified feelings for tree lace of taking pictures every time are searched using InspectEdge instruments Condition.
5. camera internal is calculated, and final result is sent into robot.
6. robot chooses whether gluing of letting pass or stop according to camera result.
7. waiting next time, product is in place
Before normal workflow is implemented, it is necessary to first carry out camera and the communication of robot and each point selection of taking pictures, And repeatedly take pictures and collect computing the two important steps.
1. camera and robot communication and point selection of taking pictures
The cylinder body for being actually needed detection is placed under camera, and robot is first intended to gluing one time according to actual tree lace track.Phase Machine is required according to the accuracy of detection of actual tree lace, selects suitable field range.The requirement of camera fields of view is installed by robot, sets Take pictures a little.The normal gluing of robot is simply taken pictures at taking pictures to camera.The communication of robot and camera simultaneously needs to set With alarm, the signals of various situations such as interrupt, in order in actual production, occur to handle under case of emergency.
2nd, camera is repeatedly taken pictures and collected
Camera takes after the completion of figure, it is necessary to carry out camera according to number of times of taking pictures according to actual tree lace and taken pictures computing.Camera is utilized Counting is detected that, when counting proceeds to a certain number, camera enables corresponding program in program to enable each section of program Duan Jinhang is detected.The corresponding instrument of each program segment is identical, but arrange parameter and threshold value can be different, great convenience The discrepant situation of gluing occurs.Last camera completes signal after the completion of counting to robot, and empties count content, is easy to Next part is counted again.Camera, which crosses the summary repeatedly taken pictures, to be judged and sends to robot.
