Description

Technical Field

[0001] The utility model relates to the technical field of ceramic product manufacturing, in particular to a robot device for drawing ceramic gold lines. Background Art

[0002] Gilding of ceramics is one of the gold color decoration methods. It is to use gold (gold powder) or bright gold (gold water) to draw decorative patterns on the porcelain surface or to use it as a border or gold ground in combination with other decorations, and then put it into the furnace for low-temperature baking. This decorative technique can make ceramic products look more gorgeous and exquisite, and is usually used to make exquisite works of art, gifts and decorations. Gilding is an important part of porcelain production. At present, it is mainly done by hand-held drawing tools. However, manual gold drawing will cause uneven thickness of the drawn gold line due to hand shaking and unstable force control. At the same time, manual gold drawing cannot accurately draw a complete circle, and some gold lines will overlap, affecting product quality and appearance. In addition, the existing buckets of gold water will settle if not stirred for a long time, and manual stirring is required from time to time. Manual gold drawing also has the defects of low work efficiency, high labor cost and high labor intensity. Utility Model Content
