Quartz crystal oscillator mainly consists of three parts: base, crystal and shell. There are two pins arranged side by side on the base. One end of the crystal is welded to the base so that the crystal is electrically connected to the two pins. The shell is covered outside the base to seal the crystal inside the shell.

The base carrier is provided with multiple slots for the pins on the base to be inserted, and the crystal carrier is provided with a guide hole for positioning the crystal. During production, the crystal carrier is assembled onto the base carrier to form a combined carrier, and then the crystal is pushed into the guide hole so that one end of the crystal abuts against the base, and finally the crystal and the base are welded. However, due to the traditional method of manual loading, workers manually insert the crystal carrier into the base carrier, resulting in low efficiency in crystal carrier loading and high production costs for enterprises.
