> An Jielun customer mainly is engaged in the high
accuracy surface pastes installs the printed wiring board (PCB) the
assembly, they request An Jielun to provide may apply for it paste to
the surface install the technology (SMT) the production line automated
optics examination system (AOI), and set the explicit request to this
system: While obtains a higher performance, the productivity and
reliable, realizes a lower cost.
Therefore, An Jielun organizes to design the team to design the
SJ50 series II automatic optics inspection machine, this is the
transformation entire PCB test family's first stage, also will be the
future entire AOI system foundation stone. Must transform this
revolutionary design, needs the splendid movement control system the
coordination, guarantees the project implementation to achieve the
specification. Through in the movement control profession strict
screening, An Jielun finally chose the MEI Corporation's movement to
control the platform and the SynqNet movement network technology,
carried on the promotion to its automated optics examination system.
The project expected completes in a year, and the realization
enhances the performance simultaneously to reduce the cost the pledge.
An Jielun the SJ50 series II automatic optics inspection machine
is section based on optics high-level inspection tool, in the
profession unprecedentedly the use solid state modelling, surveys and
prominently has the lifelike three dimensional visual effect for the
first time the part and the spot characteristic. This series may
use in the surface to paste installs the technology (SMT) in line many
positions, in front of the spot inspection backflow the part position
surveys as well as glues the two-dimensional soldering paste
inspection after the backflow.
Project description
The overall system design is completes in the different country,
mechanical platform design carries on in Ireland, the controller
design carries on in US'S Colorado state. In the entire item
design, An Jielun design group has fully considered the project and
the design unification. An Jielun movement control engineer
Barry Eppler indicated that, "The use correct kinematic scheme
meant may use in many products kinematic scheme design its repetition,
thus simplification product line, and reduces the production cost and
the development time. Through simplification training and the
support and the reduced support components stock, we also can reduce
the customer the operation cost." Therefore, An Jielun focuses
to the movement solution entire scope, causes the design throughout to
revolve three cores requests:
1. based on digital network above movement structure
2. includes the movement network the entire structure to
have to be open style
3. high performances kinematic schemes, satisfy An
Jielun the application software the request
Digital network
The digital network may improve the group of lines cost
expensive predicament which the massive simulations matches 线带
comes, thus reduces the material cost, enhances the reliability, and
permits the more complex hardware correspondence. Just like
Eppler points out, reduces the electric cable to be allowed to obtain
the obvious cost income, however the digital network superiority also
continues to this, less electric cables meant less junctions and
higher reliability. In a digital servo network, this network
itself has substituted for the traditional controller domain and the
ledger wall, causes this design to be allowed with ease to realize
promotes does not need the chassis, the power source and the coupling
baseline cost. From long term says, An Jielun hoped realizes
"the rich correspondence data path", increases the extra information
and the function. Through uses this richer correspondence, An
Jielun can realize the complex automatic disposition and the
downloading function, and carries on the automatic diagnosis.
Openness
The design group started from the project to be clear
about the design goal: System openness must pass through
throughout, but not merely limits to PC machine and the movement
subsystem, in brief, the entire control structure must open as far as
possible. Eppler explained: "This digital movement network
goal is opens also has operationally mutually ¨d¨d must truly have
the support namely to insert namely with replaces the driver the
ability." This also is product series and the realization cost
control key is at the new control structure application in An Jielun
in the AOI.
High performance movement
An Jielun design group has established the positive
performance standard as the kinematic scheme. "The high
performance" meant has the processing high speed rate encoder data
transmission the ability, the a/d conversion high resolution and the
high servo sampling rate ability, thus can enable the machine
通过?to achieve in a big way.
MEI SynqNet solution
An Jielun design group had considered the item design request,
the official appraisal and has finally chosen the SynqNet numeral
movement network architecture and the MEI XMP-SynqNet solution, as
well as comes from Kollmorgen CD the SynqNet driver. MEI the
SynqNet movement control system is one kind of high performance
network technology, this control system provides to have the cost
benefit the way, and promotes the value for new or the existing
product. MEI SynqNet is one kind may bring attachment
superiority the and so on breakdown diagnosis, performance and
reliability for the machine real-time digital network. MEI XMP
the SynqNet product and the SynqNet numeral movement network
connection may satisfy this design proposal together many requests.
Reliable mutually operating system
MEI SynqNet is the movement control network which is
open based on the ethernet and may realize mutually operates. On
the SynqNet servo driver nearly may carries on with any widespread use
operating system and movement software mutually operates.
Because the multi- operating system and calculates in the
platform all to support MPI the C/C++ storehouse, An Jielun can nimbly
choose the platform and the operating system for the next generation
machine, but does not need to fetter in the sole solution.
According to the Eppler introduction, An Jielun not only
successfully storehouse integrates MPI the C in the SJ machine,
moreover also integrates is developing to use in during other new
products application software codes.
Opening system
MEI the SynqNet numeral movement control system and the
solution movement software code is and the MEI movement programming
connection (MPI), MotionConsole™ With MotionScope™
Develops together. Eppler indicated that, "MEI
provides the newest tool, helps the development to construct the
extremely advanced movement application software, simultaneously, but
also provides in view of the customer may ship applies the encoded C
storehouse, as well as in view of project test and prototype
development ActiveX® tool."
The SynqNet open system, causes the original equipment
manufacturer and the drive seller can simply insert the correlation
technology, simultaneously has the cost benefit.
Implementation effect and user feedback
Reduced manufacture time
The SynqNet drive and the controller all the coupling
connect with simple "namely inserting", highly simplified the machine
building by the module way, thus matches the machine the line time and
several days reduces from several hours to several minutes. Like
this saved has connected in turn the time a serial electric cable
which in the system in each drive consumed, simultaneously has also
avoided the mistake which was easy in this process to produce.
An Jielun design group used MEI SynqNet to establish the basic
control structure, and started the original program design, started to
carry on the hardware platform the integration. In first stage,
because has used Kollmorgen the SynqNet driver and first generation of
MEI the XMP-SynqNet product, merely was a SJ 50 series I molding
machine has provided the new controller structure once more in day.
The first stage success, enables the design group to be allowed
very quickly to shift to the new linear module and in the high
resolution encoder new platform. In a week, this platform used
the new driver and the new controller moves. This project from
starts successfully completes to the payment initial product entire
process in year time.
Reduces the cost
With uses other digital networks or the simulated motion
control system carries on the design the machine to compare, uses
SynqNet to carry on the design the machine, may realize reduces the
cost, the simplification manufacture process, enhances the
reliability, as well as the convenience breakdown platoon looks up and
so on the application superiority. The MEI SynqNet digital
movement control solution uses an independent network electric cable
replace massively to match the line group of lines, has cancelled the
massive cable line and the traditional movement chassis,
simultaneously reduced the control system cost. Only uses
several SynqNet part, passes "namely inserts namely uses" the
controller, then realizes the system movement control.
Eppler pointed out that, "Now, our high speed machine may
provide approaches the measurement level the precision, this to our
customer said is a tremendous victory. The SJ50 series II is
providing higher 通过?and the precision, simultaneously the
system price also obtains reduces."
Promotion performance
MEI SynqNet is one kind of high performance, the entire
digital synchronized movement control network technology, can simplify
the machine design and the manufacture, and reduces the scene
technical support and the renewal and so on the related cost.
This characteristic happen to might cater to An Jielun regarding
the high performance request. SynqNet is only "may remarkably
reduce the system disposition, and may have is higher than the
traditional simulation control system performance" the digital
movement control network.
Just like An Jielun movement control engineer Barry Eppler said
that, "MEI SynqNet makes the complex application software to
become possibly, simultaneously helps us to realize to the customer
pledge: ' Reduces the cost, enhances the profit, wins in the
competition.' SynqNet is an idea perfect network, is the driver
manufacturer considered is clear about the development, this can
realize the extremely high mutually operational level."
SynqNet has met the harsh multiple spindle movement application
needs, and conforms to in the profession to be possible mutually to
operate the connection development to the total character style the
tendency. SynqNet was the machine design personnel has provided
a open style platform, enabled them to be allowed the construction
next generation machine, satisfied to reduces the electric cable
wiring, the long-distance diagnosis, firmware downloading, the multi-
suppliers supports, the network simplicity and secure and so on the
market demand. Was precisely has so many 先进?and
foresightedness, MEI the SynqNet product has only then satisfied the
automatic optics examination system (AOI) in redesign each kind of
request.
