Invisible cutting machine;
Invisible cutting machine is to score the line on to the area to be broken on the back side of the skin and invisibly from the front side.
It is mainly used to score the line for the airbag, one of the automotive
safety device. Our invisible cutting machine can store max. 2000 production
data of the depth of the score or the thickness of remaining skin after
scoring.
Main feature of this machine is the use of cold blade.
As the scoring is not made by melting the skin as in the conventional
process such as laser process or hot blade process, the mark of the score
is hard to be recognized from the front side of the skin, i.e. the surface
we usually look at. For this reason, our machine is highly appreciated
also in view of design.
Problems of conventional methods (Ultrasonic cutter, Hot blade cutter and Laser cutter)
・Heat damage of the skin can happen by using heated cutting jig.
・Because the comb-shaped heated cutter can not produce continuous score,
it is difficult to let the airbag surly be
opened by the power of airbag deployment in case that the skin thickness
is not uniform.
・Because the thermal capacity is big at the blade edge, the thermal effect is liable to go around peripheral area of the
score.
・If thickness of the skin is relatively thin, mark of the score can be recognized from the front side.
･ Stereoscopic decorative effect of the grain finish can be reduced.
・Unevenness of the surface is created around the score, by sticking of molten thermoplastic at the time of scoring.
・Due to unevenness on the back side, adhesiveness between the skin and
the foamed layer under the skin is
reduced.
・When surface of the skin is smoothed after scoring, scoring portion becomes
opened and marks of the score can be
easily recognized from the front side of the skin.
To solve above problems,
Our Invisible Cutting Machine has following features by adopting the cold cutting
method, advanced measuring technology and high precision mechanism.
・Since scoring is made keeping the skin at horizontal position, it is
possible to make precise and speedy scoring,
keeping remaining thickness uniform.
・Remaining wall thickness after scoring can be measured quickly and precisely by laser type or infrared type thickness
measuring instrument since measuring is done while the score is open.
・Even the specification of the skin such as hardness or thickness etc.
is changed, the score is surely be opened
securing enough width for accurate measurement by changing height of the projection on the supporting table.
・Cutting performance of the blade is constantly kept at a certain level.
Therefore, the remaining thickness of the skin
is kept uniform even if the type and thickness of the skin is changed.
・Thanks to the suction mechanism, even a complicated shape of skin is tentatively fixed at the desired position on the
supporting table. It prevents deterioration of production accuracy of
the score which can happen by displacement
of the skin on the supporting table.
・Easy and quick removal of the skin from the supporting table is possible by stopping suction.
・Since the distance between blade and supporting table is adjustable,
the score with uniform remaining thickness of
the skin is processed quickly and accurately.
・Optical thickness measuring device makes it possible to accurately measure and to save space.
・The machine is equipped with the detection device of conditions of cutting blade.
Therefore, it is possible to check conditions of the blade and to detect
abnormal conditions such as wearing,
damage, etc.
Our invisible cutting machine offers advanced invisibility and ensured breaking by the power of deployment of the airbag.
