Description

Technical Field

[0001] This utility model relates to the field of workpiece cleaning technology, and in particular to a workpiece cleaning device. Background Technology

[0002] Oled vapor deposition materials include metals such as ytterbium, silver, and magnesium, as well as lithium fluoride compounds. The material is placed in a vapor deposition vessel, which is fitted with a gas distribution device. Under vacuum conditions, the material is heated to melt and evaporate through the gas distribution device, depositing onto the substrate. During this process, the vapor deposition vessel and gas distribution device may become coated with material. This material must be thoroughly cleaned before each use; otherwise, the deposition effect will be compromised.

[0003] Removing deposits from vapor deposition requires the use of specific solvents (acids, alkalis, etc.) for corrosion, while simultaneously ensuring the integrity of the vapor deposition vessel and gas distribution system. It is important to note that the vapor deposition vessel and gas distribution components are fragile and must be handled with care to prevent impacts. Therefore, most existing cleaning devices employ static immersion. This cleaning method is time-consuming and inefficient. Utility Model Content
