Force control system energizing grinding polishing automation
In the
industrial manufacturing field, because of stricter standard of industrial products
art and harder to attract labor, it has become essential for the automation
upgrading, especially in grinding polishing field, its trend is more obvious.
However, in actual process, automation upgrading does not only mean in the
equipment, but also should form know-how perfect solution for the whole
industry, then can we energize factory to realize upgrading.
Anyone
who has been long in grinding polishing field all know that its producing art
requirements are complicate, abrasive material, particle size, workpiece
surface size discrepancy, touch area size, pressing magnitude, grinding angle,
beat etc. factors all are possible to make effects to grinding effect and
efficiency, which make it hard to realize manufacturing automation. Therefore,
more factories are still using traditional manual grinding method.
In a
situation in which competitionness could be different with 1 percent producing
efficiency improving, these factories are similarly desperate to improve
efficiency and yield with the help of automation. But the fact is that they can
not find the solution to help realize art effect, they have to stand and accept
manual grinding hurts and risks.
From this
point, it has appeared obvious unmatched condition in grinding polishing field
supplying end and demanding end. Grinding polishing requires higher for
flexible control, operating speed and stability in the process, the
professional degree of upstream manufacturers, deeply understanding for
grinding art become thresholds that are hard for automation equipment
integrators to step over, leading few integrators who are familiar with
grinding polishing among these many automation integrators in market.
The
obvious application hurts and customers' strong demanding for realization of
automation renovation, grinding polishing field has enough reason for
manufacturers to excavate deeply. As to how to discover these rich branch
markets, the key is at the technique ability and the market strategy.
Labor or robot for grinding and polishing?
With the
precicer and better manufacturing pushing, eco-friendly requirement in policy,
and factory itself developing need, manual as well as in robot operating has
shown some limits, and can not satisfy increasing requirements.
First,
manual operating mainly relies on personal experience. The worker can flexibly
deal with grinding polishing by their sight, touch, logical judge for any
shape,size discrepant workpieces, which is the greatest advantage of manual
grinding, the richer experience the worker has will lead higher efficiency and
better surface effect.
However,
its disadvantages are also obvious. Manual grinding only can depend on feeling
and experience, the worker can not measure how much force he imposes, neither
can he keep the force output stable, thus it can not ensure the workpiece
surface evenness and effect consistency; Uncertain manual force makes fluctuant
productivity and yield.
From
health aspect, heavy dust, noisy sound, and high frequent vibrating from
grinding machine will bring great threat to operator body health, which leads
fewer and fewer grinding workers.
Comparing
with manual grinding, robot grinding can realize high efficiency and stable
operating by programmed paths, helps enterprises improve producing effiency and
yield, cuts down cost. In the condition of workpiece materials complexity and
diversification, there are many workpiece forming arts, including sheet metal,
stamping, forging, injection molding, CNC etc, because of material character
and discrepancy of forming methods, most workpieces exist size errors, the only
difference is the data size.
Usually
industrial robot is running precisely as the path which is adjusted well, the
running path is fixed and error is very small, but if big tolerance appears on
workpiece, or any positioning discrepancy happens, grinding effect will
fluctuate a lot, what's worse, some areas are not reachable, or grinding
excessively because of too big pressure, lead low yield, and can not realize
mass production.
Besides
industrial robot, other expertised equipments also face such difficulties.
Many
enterprises in this field find this difficulty and try different solutions,
like visual distinguishing, all kinds of floating structures etc. At present,
most are researching robot combining with force sensor, through force sensor
feeling and transmitting workpiece surface changing info, then adapt to
workpiece surface changing by robot adjusting running path.
Different
from above solutions, Daru Technology (Suzhou) Co.,Ltd which is specialized in
grinding and polishing has positioned its self as flexible and intelligent
grinding system expert. For many years researching and developing, Daru has
promoted flexible and intelligent grinding system, which can realize flexible
control for force, initially adapt workpiece surface size changing in its
running process; More importantly, instantly control force magnitude in a
demanding range, can ensure workpiece surface effect even and consistent,
improve yield and make it possible to realize factory automatic mass
production.
Daru
general manager Yuqun Miao says, adding force sernsor to robot is indeed an
effective way to strengthen robot flexibility, but it is mostly used in
assembling and transferring of materials and so on; For grinding polishing
application, it needs fast and repeating movement to realize even grinding
effect, requires high for actuator instantaneity. This method has its
limitation. Though it can also realize grinding effect by slow movement, work
efficiency is relatively very low.
The core of cultivating customer's habit---solve the
hurts in this field.
The
complexity of grinding polishing art decides that it is hard to form deeply
understanding and perceiving if there is no years of deeply grounding in field
applications and customer scenes, it is just a blank promise to make values for
customers. As the founder and general manager of Daru Tech-Yuqun Miao has been
working in grinding field long for 16 years, his rich automation grinding
polishing experience, and his team's deeply understanding for grinding art,
equipment property, customer's real demanding. Surmounting customer's expect is
his team service tenet.
It is
known that current Daru Tech flexible intelligent grinding force control system
has been widely used in auto decor, public transport, 3C, stone material
sanitary ware, compound material, wood furniture etc. In mainland, the east,
south, southwest are the main service areas, In the meanwhile, in oversea
market, our products have been exported to Europe, America, Korea, Thailand et,
which is forming widely covering business network.
Yuqun
Miao thinks systematic market developing result can not divide with our
product's technique advantage.
The core
property of Daru flexible intelligent grinding force control system is to
realize flexible control for the force in the processing fo grinding polishing.
Simple to say is that it is a set of standard tool, a set of high-end
intelligent tool with controlling and executing function, fool-style designing,
easy to use, new customer can use direct by manual, usually does not need scene
support.
