Xarray should be able to do the concat step for you. I have adapted your example a bit below. It will be up to you to parse the filenames into something useful.

import glob
import pandas as pd
import xarray as xr

def time_index_from_filenames(filenames):
    '''helper function to create a pandas DatetimeIndex
       Filename example: 20150520_0164.tif'''
    return pd.DatetimeIndex([pd.Timestamp(f[:8]) for f in filenames])

filenames = glob.glob('*.tif')
time = xr.Variable('time', time_index_from_filenames(filenames))
chunks = {'x': 5490, 'y': 5490, 'band': 1}
da = xr.concat([xr.open_rasterio(f, chunks=chunks) for f in filenames], dim=time)
