Description
Technical field
The present invention relates to field of automobile, specially a kind of automobile drum brake general assembly based on machine vision
Line mistake proofing self checking method.
Background technique
Currently, the Flexible Production of automobile is constantly developed and is improved to meet people to automobile individual demand, one
The even different automobile types mixing of multi-configuration item vehicle can be achieved on production line while producing.However it is various on general assembly and total production line
Material, components are many kinds of, and in face of busy production line, part can be misplaced position or assembly error by worker, cause to produce
Efficiency and quality reduce.
Machine vision is since accuracy of identification is high, easy to use has been widely used the fields such as lathe, production line.Master of the present invention
It to be directed to while be produced different style the vehicles even flexible assemble production line of different model vehicle, installs one on the production line
Set prevention production and fabricated material misplace the NI Vision Builder for Automated Inspection of position or assembly error, and assembly is realized in allegro production
The assembly of line, recognition accuracy is high, improves production efficiency, promotes automotive quality.
Summary of the invention
The purpose of the present invention is to provide a kind of automobile drum brake general assembly line mistake proofing self-test systems of view-based access control model identification
Whether in correct position and whether assembly is qualified system quickly judge components, and easy for installation, resolution is high, solves manually to examine
The shortcomings that looking into slow speed, low efficiency, with overcome the deficiencies in the prior art.
To achieve the above object, the invention provides the following technical scheme: the automobile drum brake based on machine vision is total
Wiring mistake proofing self checking method, this method are separately mounted to components assemble production line and components general assembly assembly using trigger device
On line, wherein trigger device includes processor, camera, lighting source, alarm, trigger device and low power laser irradiation
Device, processor are connected with camera, lighting source, alarm, trigger device and low power laser irradiation unit respectively.
Preferably, the work step of components assemble production line is, when components reach designated position triggering light source and
Camera work, camera take pictures to components, and photo is stored to processor and is compared；When discovery is photographed components and specifies
Components are different, and alarm makes a sound alarm, and low power laser irradiation unit is radiated at and is identified wrong zero
On part, worker takes the components for misplacing position away, and components are continued to be transported on general assembly assembly line if errorless.
Preferably, the work step of components general assembly assembly line is to be mounted in vapour when worker will be identified correct components
After vehicle appointed part, trigger device will be to instruction lighting source and camera work, and camera is by the photograph of the photo photographed and storage
Piece comparison, if identifying, components assembly is unqualified, and low power laser irradiation unit will be radiated at assembly underproof zero
On part, the components of worker's adjustment assembly complete fittage if assembling qualification.
By adopting the above technical scheme, compared with prior art, the beneficial effects of the present invention are: may not need under artificial detection
It can find whether components are put to position and assembly qualification, mechanism is simple, and easy for installation, invention has the advantages of high efficiency, and identification is accurate
Rate is up to 95% or more, and effect stability can effectively improve automobile manufacture efficiency and quality.
Detailed description of the invention
Fig. 1 is work flow diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: the automobile drum brake general assembly line based on machine vision is anti-
Wrong self checking method includes two production lines on auto assembly line, and one is components shipping line, and another is that components are total
Wiring；Mistake proofing self-test station based on machine vision is respectively set on two production lines；On the mistake proofing self-test station
It is provided with processor, camera, lighting source, alarm, trigger device and low power laser irradiation unit, processor difference
With camera, lighting source, alarm, trigger device and low power laser irradiation unit are connected.
A kind of automobile drum brake general assembly line mistake proofing self-checking system based on machine vision, implementation step: automobile zero
Component is put into components shipping line, and after trigger device, trigger device obtains processor to processor signal, lighting source
Instruction after, light source is beaten light on components, and camera is taken pictures, and photograph is compared by processor, if discovery zero
Part is not placed on specified position, and processor issues instruction alarm to alarm, while instructing to low power laser irradiation unit, will
Laser impinges upon on the components for misplacing position, prompts worker that components are reapposed over correct position；If out of question, components
Into assembly line, components are mounted on automobile designated position by worker, and after having assembled, processor signal is given in trigger device work,
Processor beats light order lighting source on the components assembled, and camera is taken pictures, and photo is compared in processor
Right, if unqualified, alarm equipment alarm is assembled in discovery, laser irradiation is being assembled not up to standard zero by low power laser irradiation unit
On part, worker is prompted；If assembly is qualified, the process which successfully completes assemble production line, into subsequent processing.
Case is embodied
In the implementation case, by taking the assembly of the brake-shoe of automobile drum brake as an example, brake-shoe is placed on components shipping line
On, when brake-shoe moves to trigger device, signal is transmitted to processor by trigger device, under the instruction of processor, lighting source
It works with camera, camera passes photo back processor and carries out real time contrast, if comparison is incorrect, alarm device alarm, low-power swashs
Light irradiation device beats laser on the brake-shoe of error, and worker places brake-shoe position again；If not alarming, brake-shoe is transported
Onto assembly line, after worker installs brake-shoe, trigger device will give processor signal, and lighting source and camera obtain letter
Number work, photo passed back processor and is compared by camera, if alarm device is alarmed, low-power irradiation unit will be radiated at assembly not
On qualified brake-shoe, worker continues to assemble brake-shoe, until not alarming；If not alarming, brake-shoe completes assembler
Sequence, into next process.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
