- the transfer rail is restarted to introduce the lower pane with the ceramic ink layer into the furnace.
- the ceramic ink layer formed on the lower pane was dried at a furnace for 3 minutes at 200 ° C. and then calcined at 400 ° C. to a patterned spacer.
- a patterned spacer made of a metal material (stainless steel SUS304) having a diameter of 0.5 mm and a height of 0.25 mm is formed on the spacer alignment plate at intervals of 20 mm.
- the patterned spacer formed on the spacer alignment plate may be seated and transported to a seating machine, and thus the patterned spacer may be manufactured by detaching the spacer on the lower plate glass (FIG. 10).
- the patterned spacer (Example) formed by drying the ceramic ink has no spacer seating failure, and the cycle time is lower than that of the comparative example, resulting in high productivity and high freedom in the shape and arrangement of the spacer.
- Spacers and arrangements are possible.
- defects that do not rest in the correct position of the spacer may appear, and thus a separate repair function is required, and the cycle time is also high compared to the embodiment, and the productivity is low.
- the spacer in order to change the shape or arrangement of the spacer, the spacer must be manufactured separately, and the mounting facilities corresponding thereto must be changed.
- the embodiment has the advantage of freely changing productivity and spacers.
