Labor intensity.
Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, it is explained below in conjunction with embodiment.
The present invention provides a kind of engine main bearing cover assembly vision inspection apparatus, including vision system, PLC and alarm
Device；The vision system includes photoelectricity visual sensor, computer；There are two the photoelectricity visual sensors, respectively front and back cloth
It sets in the top and side of production line, previous is part alignment sensor, and automatically and accurately to trigger sampling, the latter is used
In the morphology of Dynamic Recognition main beating cap；Two photoelectricity visual sensors are connect with computer respectively, and will be adopted
Collection information is sent to computer, and computer and alarm are connect with PLC.
The present invention provides a kind of engine main bearing cover assembly visible detection method, includes the following steps:
Step 1: tightening one inspection of setting between assembly station and station turning in engine main bearing cover assembling line
Station is surveyed, the top and side of the production line in the detection station are respectively arranged photoelectricity visual sensor；
Step 2: engine cylinder body complete main beating cap tighten process after, moved along roller-way to detection station；
Step 3: when engine enters detection station, part alignment sensor detects the 1st main beating cap edge first,
The geometry for identifying its front end by another sensor immediately, through computer sampling, processing；
Step 4: engine cylinder body continues to move forward, and the detection and identification process of step 3 are repeated to subsequent main beating cap；
Step 5: computer is by judging whether misloading part compared with preset value, if main beating cap assembly is complete
Portion is correct, then engine cylinder body continues to flow to next station, and otherwise alarming and issuing to PLC instructs, and makes production line stop, will have
The engine cylinder body of problem is offline to be reprocessed.
By taking four cylinder engine as an example.The front end of 5 main beating cap is in different step-like.Pass through the number on each part
Word mark, is installed by regulation sequence and direction.Since part mixes, quantity is again big, Chang Fasheng misloading phenomenon leads to next procedure
Generate waste product.
For this purpose, a detection station is arranged between assembly station and station turning in tightening for production line, by automatic identification,
The correctness of judgement assembly result.If all correct, cylinder body continues to flow to next station, otherwise alarms and refers to PLC sending
It enables, makes production line stop, reprocess problematic cylinder body is offline.In order to adapt to the assembly beat of 1/minute, using in cylinder body
It is detected in moving process, front and back is arranged in the top and side of production line to 2 photoelectricity visual sensors respectively.Previous is part
Alignment sensor, automatically and accurately to trigger sampling, the latter is used for the surface geometry shape of 5 main beating cap of Dynamic Recognition
Shape.According to each main beating cap characteristic parameter and collected sensor output signal being pre-filled with, it may be determined whether it is wrongly installed simultaneously
Indicate specific Error Location.
Entire detection, identification process are as follows: cylinder body complete main beating cap tighten process after, moved along roller-way to detection station
It is dynamic, and the effect of contraction of two side rails, it ensure that part automatic capturing position.When entering detection station, alignment sensor is first
The 1st main beating cap edge is first detected, identifies the geometry of its front end by another sensor immediately, via controller is adopted
Sample, processing；Then cylinder body continues to move forward, and the 2nd~5 main beating cap is detected and identified.By compared with preset value, just
Whether misloading part can be judged.Detection has counting and display every time, and entire detection process is in cylinder body conveying is mobile
It completes, it is not necessary to additionally increase detection time.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not limited to this hair the foregoing is merely a specific embodiment of the invention
Bright, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
