Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
A kind of composite and flexible windscreen recognition methods, as shown in Figure 1, it includes the following steps:
Step 1: be equipped on the delivery vehicles (suspender or slide plate) of vehicle RFID carry code device electronic tag 1, vehicle it is defeated
It send and RFID is installed on track carries code device reader 2, in general assembly pipeline transport process, upstream MES information system 3 is by real-time vehicle
Type information passes to the main cabinet PLC4 of RFID system, and on vehicle when first station of assemble production line, the main cabinet PLC4 of RFID system will
The real-time vehicle model information got carries code device reader 2 by RFID and is written in RFID load code device electronic tag 1；
Step 2: automatic double surface gluer 5 shifts to an earlier date three stations and carries the acquisition RFID load code device electronics mark of code device reader 2 by RFID
Corresponding vehicle model information at this time in label 1, and be shown on the industrial personal computer display of automatic double surface gluer；
Step 3: the vehicle model information that operating personnel obtains according to automatic double surface gluer 5 places corresponding vehicle on automatic double surface gluer 5
Glass；
Step 4: the standard feature supplemental characteristic for needing all vehicle glass of gluing is prestored in the work station of automatic double surface gluer 5
Library, the length and width that glass is arranged are characterized parameter, and the standard feature supplemental characteristic of vehicle glass is established in the form of two-dimensional array
Library (xi,yi), i=1,2,3 ..., n, x in formulaiFor the length of normal glass, yiFor the width of normal glass, n indicates glass number；
The corresponding unique a kind of mark of each group of glass length and width characteristic parameter in the standard feature parameter database of vehicle glass
Quasi- glass model and vehicle model information are each model in the standard feature parameter database of vehicle glass in automatic double surface gluer 5
Normal glass corresponding robot coating program is arranged according to corresponding glass length and width characteristic parameter, by being based on centering clamp
Glass profile measurement mechanism, obtain the actual characteristic value (x, y) of gluing glass, and traverse that calculate the practical length and width of gluing glass special
The various known models normal glass length and width characteristic parameters levied in the standard feature parameter database of parameter and vehicle glass carry out
Length and width characteristic matching, so that it is determined that whether gluing glass is known models normal glass, if it is, determining gluing glass simultaneously
Corresponding specific standards glass model；
Step 5: automatic double surface gluer 5 according to it is matched as a result, select the robot coating program of corresponding model normal glass into
Row glass glue-spreading.
In the step 5 of above-mentioned technical proposal, also need to carry out vehicle model information before the progress glass glue-spreading of automatic double surface gluer 5 matched
Judgement, only after vehicle model information matching judgment passes through, just can be carried out glass glue-spreading.
In above-mentioned technical proposal, the method for the vehicle model information matching judgment are as follows:
The main cabinet PLC4 of RFID system will pacify what RFID load code device reader 2 was read outside glazing vehicle model information and glass
The corresponding vehicle model information of gluing glass actual characteristic value (x, y) that shape testing agency identifies is compared, if the two is consistent,
Vehicle model information matching judgment passes through；If inconsistent, alarm lamp flashing, and occur " vehicle compares inconsistent alarm " on screen,
Equipment never calls program, and workbench exits station, and glass by manually taking away, remove automatically accordingly by corresponding comparison bar code.
In above-mentioned technical proposal, traversal calculates gluing glass actual (tube) length quant's sign parameter and the standard feature of vehicle glass is joined
Number databases in various known models normal glass length and width characteristic parameters carry out length and width characteristic matching specific method be, according to
Following formula calculate in the standard feature parameter database of gluing glass actual (tube) length quant's sign parameter and vehicle glass it is various
Know the error R between model normal glass length and width characteristic parameter:
Wherein, x is the physical length feature of gluing glass, and y is the developed width feature of gluing glass, xiFor normal glass
Length, yiFor the width of normal glass；
It is less than the normal glass model of setting error amount δ if there is error R value, then the success of length and width characteristic matching, error
Value δ can be adjusted according to the size of the characteristic difference of practical gluing glass, the precision of identification can effectively be controlled, thus quasi-
Really identification vehicle model information.
The present invention is handled by having a double meaning mistake proofing, and Lai Tigao stepping glass identifies accuracy, and first closes by conveying device
The electronic chip of carrying reads vehicle queue information, and is shown on the industrial personal computer display of windscreen assembly station, and be equipped with
Misloading warning device.Second closes to build sharp standard feature database according to the resemblance of normal glass, by being pressed from both sides based on centering
The glass profile measurement mechanism of tool, calls corresponding robot coating program.The information of vehicles that first electronic chip closed is read
The information of vehicles for the glass centering fixture identification closed with second is compared, and the corresponding program of equipment calls starts to apply if consistent
Glue, if inconsistent, alarm lamp flashing simultaneously occurs " vehicle compares inconsistent alarm " on industrial personal computer display, and equipment is never called
Program.
The content that this specification is not described in detail belongs to the prior art well known to professional and technical personnel in the field.
