Furthermore, it is important to note that as the core cell of automotive hub mark system for tracing and managing,
Above-mentioned machine vision unit is in addition to being integrated in native system, it is also possible to be independently realized as wheel hub type identification
Unit.Specifically, wheel hub type identification unit may utilize camera and captures visual field picture, such as but not limited to
Search following possible identification feature: 1) inner flange image；2) wheel-type cast and mould number identify two
Dimension code or one-dimension code；3) the mould identifier cast.It follows that wheel hub type identification unit is according to being identified
The characteristic information (such as inner flange image) gone out and the comparison of the predetermined information in the template base of training
As a result, judge that wheel-type i.e. realizes wheel-type identification.
In other words, it is simply that wheel hub type identification unit needs the type reading die casting machine mark at workpiece inner flange
Number cognizance code, or identification wheel hub type in the way of multiple redundancy realizes.Here " type identifier code "
It is that casting (please noting it is not to be identified by native system) in advance is at the Quick Response Code of certain type wheel hub, for example, as
Wheel-type code name is certain type wheel hub of 02214F13, and the wheel hub producing this model may have multiple stage die casting machine to work,
The most multiple molds produce simultaneously, and mold can cast a Quick Response Code at certain ad-hoc location, such as No. 2
The Quick Response Code that mold casting is one 221302 is on its wheel hub produced, and 2213 represent that wheel-type are 02214F13,
02 represents No. 2 molds；No. 3 molds cast the Quick Response Code of 221303 on its wheel hub produced, and 2213
Representing that wheel-type is 02214F13,03 represents No. 3 molds；So wheel hub type identification unit picks out Quick Response Code
I.e. know wheel-type and mould number.But the most this casting Quick Response Code is by casting technique, light, surface
The multiple accidentalia such as fineness and material affects, and discrimination is extremely low.So in the specific place of another one,
Mold can cast similar M2 or M3 and identify mold number, and the reliability of system identification M2 or M3 is high.
So it is obtained with mould number, can obtain with board binding according to the sequencing of wheel hub as wheel-type information
Obtain (mould number can also be obtained) simultaneously, can obtain in the way of carrying out Graphic Pattern Matching to identify its shape simultaneously,
Thus by the way of realizing, identify wheel hub type with multiple redundancy, it becomes possible to significantly increase wheel hub type
The accuracy rate identified.
Incidentally point out why need to obtain relevant geometry physical basis data according to wheel hub type, be
Because the size shape of different wheel hub types and three-dimensional dimension difference are the biggest, how many individual for camera
Pixel represents a mm, is the important parameter of a variation, therefore the pixel of visual field needs and geometry physical basis
Data Corresponding matching, is only possible on equipment realize the location of multiple wheel-type simultaneously.
Additionally, the basic data of native system is briefly described.The basic data of device parameter not only realizes
Spinning board (die casting machine), operator on duty etc. associate with system, but also achieve people and machine
Key element associates, and meanwhile, wheel-type cognizance code and top stem casing identifier then achieve the pass of product and system
Connection.
Native system possesses the ability of many wheel-type multi-mould Flexible production, all physical appearance sizes being suitable for wheel-type
All existing in data base etc. information, during work, system is automatically called relevant wheel-type data and is completed work.Different
There is job function and the division of data use authority in authorized person, system depends on central authorities and completes with server
Role and rights management.System is arranged and other operational factor is typically entered by engineer or assigned work personnel
Row operation.Specifically, basic data specifically includes that
● device parameter, such as
Die casting machine (spinning machine) machine station information
Workshop section's machine station information
Operator's identity code
Wheel-type cognizance code
Quick Response Code top stem casing and mould identifier
● wheel hub data, such as
The physical appearance size of wheel-type, gabarit diameter, highly, and loss of weight nest ring flange size, flange face
Highly, the loss of weight nest degree of depth
Corresponding process route chart
● user authority management, such as
Right of using functions,
Business datum zone permission
Obligational authority；
● system is arranged, such as

Then, illustrate that the automotive hub mark system for tracing and managing utilizing the present invention carries out wheel hub with reference to Fig. 2
The workflow of mark.Wherein it is preferred to use laser-marking equipment to identify equipment as wheel hub.
First, field engineer needs to use relevant software (such as VISIONPRO) to train native system
Instruction, it is also desirable to the basic data of pair wheel type is acquired, such as, includes PCD diameter, installing blind
Number and loss of weight nest position etc., these Back ground Informations are stored in the data of the industrial panel computer of native system
In storehouse (Step 1: system training)。
Then, wheel hub to be identified is directed to working region, and first clamping device is transmitting horizontal direction to wheel
Hub carries out positioning in team, is then held up supreme bearing plate position, and upper bearing plate clamping device is to before and after it
Location, and be fixedly clamped i.e. identify in operating position station (Step 2: clamping position)。
Then, machine vision unit is sent camera and triggers signal, in order to start machine visual unit pair wheel type
And/or mould number realizes identifying and pre-determined bit task.Specifically, camera can capture visual field picture, such as but
It is not limited to search following possible identification feature: 1) inner flange image；2) wheel-type cast and mould number
Identify Quick Response Code or one-dimension code；3) the mould identifier cast.It follows that machine vision unit is according to being known
The characteristic information (such as inner flange image) not gone out and above-mentioned predetermined information in the template base of training
Comparative result, prejudge wheel-type and i.e. realize wheel-type identification.And then, according to image calculation installing blind
And loss of weight nest position, and detection casts Quick Response Code or one-dimension code feature and mould identification respectively in resolving region
Number (Step 3: feature identification)。
Then, complete to identify and after pre-determined bit task, by loss of weight nest position to be identified at machine vision unit
Visual field coordinate figure resolves and is converted to the coordinates of motion, and the motor system for clamping and location is according to the coordinates of motion
Capturing wheel hub, industrial camera is moved to target characteristic (loss of weight nest to be identified) by simultaneity factor,
With measurement and positioning accurate to target characteristic.Machine vision unit is respectively completed Quick Response Code or one-dimension code (private mark)
With the accurate measurement and positioning of readable character (plain code) loss of weight nest, middle servosystem can adjust camera automatically
Operating position (Step 4: position measurement to be identified positions)。
It follows that after all identifications and measurement and positioning complete, private mark loss of weight nest is focused by system, adjust and swash
The position, 3 directions of light mark equipment.System, the most according to the wheel-type identified, inquires about central service
Device data base, generates the unique identities identifier of workpiece, and the information of 12 is transmitted and give laser-marking and set
Standby.Behind the position and data ready of laser machine, trigger laser mark printing device to start to etch private mark.
After private mark etches, system adjusts laser machine position again, owing to being previously complete laser machining process
Distance focusing, so secondary adjustment only relates to X and Y-axis both direction.Call laser machine plain code template simultaneously,
Again trigger laser mark printing device, start to etch readable character plain code (Step 5: etching plain code and private mark)。
As combined shown in Fig. 5 to Fig. 7, it is defined as follows about X, Y and Z-direction: i.e. raceway transmits
Front is Y-axis forward, and the dextrad of transmission forward direction is X-axis forward, is the forward of Z axis vertically upward.Need
It is noted that when system is energized for the first time or chance failure automatically recovers, servosystem can be resetted by system,
Now servosystem is adjusted to each axle origin position.
Finally, after laser machining process completes, laser machine is returned to the operating position preset by system automatically,
And trigger machine vision unit and perform private mark and plain code character checking reading task.Now, wheel hub clamping dress
Put and start to send back to wheel hub raceway, and spinning machine gating signal is passed to roll pipe transmission system (Step 6: Plain code/private mark checking)。
Here, need subsidiary explained be because wheel hub in mark station transfixion, and subtracting of identifying
Weight nest position be random, therefore need laser machine, the camera of machine vision unit carry out motion be only possible to location
Mark.Therefore, in plain code/private mark verification step, when laser machine etched product identification Quick Response Code or
After one-dimension code private mark and readable plain code character string, system needs the working position that laser machine returns to preset
Put, i.e. central authorities are playbacked, the most just obtain visual angle basically identical after positioning with wheel hub, in order to read and carved
The private mark of erosion.Then, wheel hub raceway to be returned to enters subsequent production flow process, and reads the result of private mark
Also being associated with system, the 02214F13 wheel hub the most simultaneously produced will be to No. 1 spinning machine, and 22Z50 takes turns
