Building an Automatic Experience Collector for Minecraft
Creating your own experience storage device couldn't be easier! You only need three items: a chest, an item frame, and a glass bottle.
First, place the chest in a convenient location, then position an item frame on it. Place the glass bottle inside this frame - and your automatic experience collector is ready for operation!

Device Operating Principle
This special chest acts as a magnet for experience orbs within a 12-block radius. All found orbs are automatically converted into stored experience. When the accumulated experience reaches or exceeds 7 units (the standard value corresponding to one bottle of enchanting), one bottle of enchanting appears in the chest, which you can use to replenish your enchantment levels.
