Abstract

The present disclosure provides a cache device and a LCD screen production line. The cache device provided by the present disclosure includes an outer frame having an opening for picking and placing cached items on a first side wall thereof and a support bracket for horizontally supporting cached items therein; and first blowing means disposed on the second side wall of the outer frame for blowing air toward the opening; second blowing means disposed on the third side wall or the fourth side wall of the outer frame; an exhaust means disposed on a fourth side wall opposite to the third side wall of the frame.

First claim

What is claimed is:

1. A cache device, comprising:
a frame, a first side wall of which has an opening for picking and placing cached items;
a support bracket located in an area surrounded by the frame for supporting cached items;
first blowing means on a second side wall opposite to the first side wall of the frame; the first blowing means being configured to blow air toward the opening;
second blowing means on a third side wall of the frame adjacent to the first side wall; and
exhaust means disposed on a fourth side wall opposite to the third side wall of the frame.

2. The cache device according to claim 1 , further comprising: third air blowing means provided on a fifth side wall of the frame; at least one vent provided on a sixth side wall opposed to the fifth side wall.

3. The cache device according to claim 2 , wherein the second blowing means is configured that the pressure of the air stream blown is not less than the pressure of the air stream blown by the first blowing means, and/or the third blowing means is configured that the pressure of the air stream blown is not less than the pressure of the air stream blown by the second blowing means.

4. The cache device according to claim 2 , wherein the fourth side wall comprises a vertical guide plate, on which at least one guide hole is arranged.

5. The cache device according to claim 2 , wherein,
the first blowing means includes a plurality of EFUs arranged in a rectangular array; and/or,
the second blowing means and the third blowing means each include a plurality of nozzles adapted to be in communication with a source of compressed dry air; and/or,
the exhaust means is a vacuum exhaust means.

6. The cache device according to claim 5 , wherein the nozzle is a 360° rotating nozzle.

7. The cache device according to claim 2 , further comprising detecting means and a controller, wherein the detecting means is configured to detect a storage state in the cache device; and the first blowing means keeps operating when the cache device is in normal working state; the detecting means sends a start signal to the controller when the idle time of the cache device exceeds a predetermined period of time; and the controller controls the second blowing means and the exhaust means to start according to the start signal, allowing the second blowing means and the exhaust means to operate for a predetermined period of time.

8. The cache device according to claim 7 , wherein during the operation of the second blowing means and the exhaust means, the detecting means, when detecting that a cache item is stored in the cache device, sends a stop signal to the controller, which in turn controls the second blowing means and the exhaust means to stop according to the stop signal.

9. The cache device according to claim 7 , further comprising: an input unit which is in signal connection with the controller, which controls the start and stop of the third blowing means according to the information input from the input unit.

10. A liquid crystal display screen production line equipped with the cache device according to claim 1 .
