Sputter tray moving system
View Patent ↗A sputter tray moving system includes a sputter tray, a guide disposed under the sputter tray and including a groove, a pulley engaged with the groove of the guide and a buffer member disposed between the sputter tray and the guide. The sputter tray is moved when the pulley engaged with the groove of the guide is rotated in a rotation direction.
1. A sputter tray moving system comprising:
a sputter tray;
a guide disposed at an inside of the sputter tray, and including a groove which protrudes from a lowermost edge of the guide to an inside of the guide;
a pulley engaged with the groove of the guide; and
a buffer member disposed between the sputter tray and the guide,
wherein
the sputter tray is moved when the pulley engaged with the groove of the guide is rotated in a rotation direction,
inner walls of the sputter tray are slidably disposed with respect to outer walls of the guide, such that the inner walls of the sputter tray are moveable toward and away from the pulley, and
the groove of the guide is longitudinally extended in the rotation direction.
2. The sputter tray moving system of claim 1 , wherein
outer surfaces of the pulley directly contact inner surfaces of the groove of the guide.
3. The sputter tray moving system of claim 2 , wherein
inner surfaces of opposing sides of the groove of the guide, with respect to the pulley, are tapered in a cross-sectional view along the rotation direction.
4. The sputter tray moving system of claim 3 , wherein
the pulley has a wedge shape in a cross-sectional view of the pulley in the rotation direction.
5. The sputter tray moving system of claim 4 , further comprising
a motor driving the pulley.
6. The sputter tray moving system of claim 5 , wherein
the pulley and the motor are connected to each other through a driving shaft.
7. The sputter tray moving system of claim 1 , further comprising
a fixing member fixing the guide to the sputter tray.
8. The sputter tray moving system of claim 7 , wherein
the groove of the guide is provided as a plurality thereof.
9. The sputter tray moving system of claim 8 , wherein
the pulley includes a plurality of a protrusion.
10. The sputter tray moving system of claim 9 , wherein
the protrusions are disposed according to the circumference of the pulley, and are respectively engaged with the grooves of the guide.
11. The sputter tray moving system of claim 1 , wherein an entire of the buffer member is at the inside of the sputter tray.
12. A sputter tray moving system comprising:
a sputter tray;
a roller rotatable in a first direction;
a guide disposed at an inside of the sputter tray, and including a groove which protrudes from a lowermost edge of the guide to an inside of the guide and longitudinally extends in the first direction; and
a buffer member disposed between the sputter tray and the guide,
wherein
an outer surface of the roller is engaged with and contacts an inner surface of the groove of the guide, such that the sputter tray is moved in the first direction when the pulley is rotated in the first direction, and
inner walls of the sputter tray are slidably disposed with respect to outer walls of the guide, such that the inner walls of the sputter tray are moveable toward and away from the roller.
13. The sputter tray moving system of claim 12 , wherein
the buffer member is deformable in a second direction substantially perpendicular to the first direction, when the sputter tray is moved in the first direction.
14. The sputter tray moving system of claim 13 , wherein
the guide further includes a plurality of the groove disposed substantially parallel with each other; and
the roller includes a plurality of a protrusion each longitudinally extended in the first direction and disposed respectively contacting a groove of the guide.
