Abstract

A magnet plate for manufacturing a display device is disclosed. In one aspect, the plate includes at least two magnet units formed in a first direction, each magnet unit including first and second linear motion (LM) guides. The plate also includes a support plate attached to the LM guides. The magnet unit also includes a magnet supporter comprising an upper portion including a magnet coupling part, a lower portion including a plurality of cam followers, and at least two first transfer plate coupling protrusions formed at a predetermined interval. The magnet unit further includes a magnet guide plate placed beneath the magnet supporter and including a guide cam hole into which the cam follower is inserted. The guide cam hole is oblique with respect to the first direction and has a predetermined width such that the cam follower moves within the guide cam hole.

First claim

What is claimed is:

1. A magnet plate for manufacturing a display device, comprising:
at least two magnet units formed in a first direction, wherein each magnet unit includes first and second linear motion (LM) guides; and
a support plate attached to the first and second LM guides, wherein the magnet unit further includes:
a magnet supporter comprising i) an upper portion including a magnet coupling part, ii) a lower portion including a plurality of cam followers, and iii) at least two first transfer plate coupling protrusions formed at a predetermined interval, wherein the magnet supporter extends in the first direction;
a magnet guide plate placed beneath the magnet supporter and including i) a guide cam hole into which the cam follower is inserted, wherein the guide cam hole is oblique with respect to the first direction and has a predetermined width such that the cam follower moves within the guide cam hole, and ii) a connection hole configured to communicate with the first transfer plate coupling protrusion and has a predetermined width such that the first transfer plate coupling protrusion moves within the connection hole, wherein the magnet guide plate extends in the first direction;
a first transfer plate connected to the first transfer plate coupling protrusion penetrating through the connection hole;
the first LM guide connected to the first transfer plate and a lower portion of the first transfer plate, wherein the first transfer plate is configured to move along the first LM guide in a second direction crossing the first direction;
a second transfer plate connected to a lower portion of the magnet guide plate;
the second LM guide connected to the second transfer plate and a lower portion of the second transfer plate, wherein the second transfer plate is configured to move along the second LM guide in a third direction crossing the first and second directions; and
a moving device mounted at a first end of the magnet guide plate and configured to linearly move the magnet guide plate.

2. The magnet plate of claim 1 , wherein the at least two magnet units include a plurality of odd-numbered magnet units and a plurality of even-numbered magnet units, and wherein the first LM guide includes i) a first integrated guide connected to the first transfer plate of at least one of the odd-numbered magnet units and ii) a second integrated guide connected to the first transfer plate of at least one of the even-numbered magnet units.

3. The magnet plate of claim 1 , wherein the moving device includes a rack gear mounted at the first end of the magnet guide plate and a worm gear contacting the rack gear.

4. The magnet plate of claim 3 , wherein the rack gear is mounted on i) the upper portion or the lower portion of the magnet guide plate of the odd-numbered magnet units and ii) the lower portion or the upper portion of the magnet guide plate of the even-numbered magnet units, and wherein the upper and lower portions of the magnet guide plate of the odd-numbered magnet units respectively correspond to the lower and upper portions of the magnet guide plate of the even-numbered magnet units.

5. The magnet plate of claim 3 , further comprising an actuator connected to the worm gear so as to apply a predetermined amount of torque.

6. The magnet plate of claim 3 , further comprising:
a plurality of clutches connected to the worm gear; and
an actuator configured to apply a predetermined amount of torque to the clutches.

7. The magnet plate of claim 6 , further comprising a controller configured to control at least one of the actuator and the clutches.

8. A magnet plate for manufacturing a display device, comprising:
at least two magnet units formed in a first direction and including first and second linear motion (LM) guides, wherein each magnet unit includes:
a magnet supporter comprising i) an upper portion including a magnet coupling part, ii) a lower portion including a plurality of cam followers, and iii) at least two first transfer plate coupling protrusions formed at a predetermined interval, wherein the magnet supporter extends in the first direction;
a magnet guide plate placed beneath the magnet supporter and including i) a guide cam hole into which the cam follower is inserted, wherein the guide cam hole is oblique with respect to the first direction and has a predetermined width such that the cam follower moves within the guide cam hole, and ii) a connection hole configured to communicate with the first transfer plate coupling protrusion and has a predetermined width such that the first transfer plate coupling protrusion moves within the connection hole, wherein the magnet guide plate extends in the first direction;
a first transfer plate connected to the first transfer plate coupling protrusion penetrating through the connection hole;
the first LM guide connected to the first transfer plate and a lower portion of the first transfer plate, wherein the first transfer plate is configured to move along the first LM guide in a second direction crossing the first direction;
a second transfer plate connected to a lower portion of the magnet guide plate;
the second LM guide connected to the second transfer plate and a lower portion of the second transfer plate, wherein the second transfer plate is configured to move along the second LM guide in a third direction crossing the first and second directions; and
a moving device mounted at a first end of the magnet guide plate and configured to linearly move the magnet guide plate.

9. The magnet plate of claim 8 , wherein the at least two magnet units include a plurality of odd-numbered magnet units and a plurality of even-numbered magnet units, and wherein the first LM guide includes i) a first integrated guide connected to the first transfer plate of at least one of the odd-numbered magnet units and ii) a second integrated guide connected to the first transfer plate of at least one of the even-numbered magnet units.

10. The magnet plate of claim 8 , wherein the moving device includes a rack gear mounted at the first end of the magnet guide plate and a worm gear contacting the rack gear.

11. The magnet plate of claim 10 , wherein the rack gear is mounted on i) the upper portion or the lower portion of the magnet guide plate of the odd-numbered magnet units and ii) the lower portion or the upper portion of the magnet guide plate of the even-numbered magnet units, and wherein the upper and lower portions of the magnet guide plate of the odd-numbered magnet units respectively correspond to the lower and upper portions of the magnet guide plate of the even-numbered magnet units.
