Description

Technical Field

[0001] The utility model belongs to the technical field of silicon wafer sorting machines, and particularly relates to a guide rail protection cover and a material lifting box thereof. Background Art

[0002] The silicon wafer sorter is used in the inspection process of silicon wafer production. After the silicon wafers finish the cleaning process, they are classified by the sorter and silicon wafers of different quality grades are loaded into different material boxes. The material boxes will be raised and lowered once at a specified time. The operator at the material box position is easy to contact the guide rail. There is a large amount of lubricating oil on the guide rail. During the operation, the operator's fingers will be covered with oil, which will contaminate the silicon wafers when taking them, affecting the yield rate of the silicon wafers. In addition, material boxes of different grades will be raised and lowered from time to time, and there is a risk of operators pinching their hands. More importantly, the guide rails have no protective folding covers and are directly exposed to the production environment. Long-term use will cause the guide rails to be filled with a mixture of dust and lubricating oil, which will not only affect the appearance of the guide rails, but also affect the lubrication of the guide rails over time, causing jamming and damage, reducing the service life of the guide rails.
