Our oak tree dumps a lot of acorns on the lawn. What is the best way to get them out of the lawn?

There really isn't any magical solution to getting them out of the lawn. The best way to clean up acorns is simply to rake or vacuum them up. Another option is just to leave them on the ground and the insects and squirrels will soon devour them. Acorns make a good addition to the compost pile. Collect them in a burlap bag and then drive over them a few times with the car before tossing them on the heap. This will help them breakdown faster.
If you've never tried harvesting them for their meat, try it. It might make cleaning them up more tolerable. Acorns are high in fiber, complex carbohydrates, vitamins, and minerals. They are also relatively low in fat compared to other nuts. The meat of the nut is too bitter to snack on like other nuts, so it is usually processed into meal and used the same way that corn meal is used. Burr, white and swamp oak acorns contain the least amount of tannins.
To harvest, collect only acorns without any visible holes on the shells. Lay them out on a cookie sheet and dry them in the over at 175 degrees from about an hour (stir them to prevent burning). Crack the shells open and remove the meat. The meat should be yellow, not black or moldy. Place the meat in a food processor or run it through a grinder. Place the ground meat in a large bowl and pour hot or boiling water over it. Let it stand for 1 hour and them drain off the murky-colored water (tannins). Continue to do this until the meat loses its bitter flavor and then dry the meat in a food dehydrator or on a cookie sheet in the over on low heat. When the meat is completely dry, grind it into a fine meal using a grain mill or stone. Store the meal in the freezer until you need it.

Acorns can be eaten but you will likely get a stomach ache due to the high tannin content. Acorns must be leached 3-4 times first, before being eaten.
We just rake them up with the leaves and toss the whole mess back into the forest on our land.
