A chip packaging device is provided, which includes a main body unit, packaging unit and an aligning unit. The main body unit includes a mounting base, holder and a rotational platform. The packaging unit includes upper and lower bonding elements, upper and lower chips and a mask; a vertical axis is at the middle of the upper and the lower bonding elements, and a horizontal axis is above the lower bonding element. The aligning unit includes an aligning detector and a first focusing detector. When the lower chip and the mask are disposed on the lower bonding element, place the liquid sample in the mask and spread a packaging adhesive over the surface thereof; then, remove the mask and use the aligning detector and the first focusing detector to detect the position of the lower chip respectively, such that the chips can be aligned and bonded with each other.

The present invention provides a packaging unit for liquid sample loading devices applied in an electron microscope. The liquid sample loading devices may be easily, rapidly, precisely and stably aligned and packaged by an engagement of an upper jig and a bottom jig as well as a first fixing pillar supported in a slide track of the packaging unit. Accordingly, efficiency and a yield of packaging the liquid sample loading devices may be improved. In addition, the packaging unit for the liquid sample loading devices of the present invention may directly package a liquid sample, and thus the liquid sample may maintain its original state.
