Abstract
Description
Technical Field
[0001] This utility model relates to the field of tissue section scanner technology, and in particular to a rotating mechanism. Background Technology
[0002] A tissue section scanner is a high-precision digital device used in basic medical fields. It is mainly used to quickly convert biological tissue sections (such as pathological samples and research specimens) on traditional glass slides into high-resolution digital images. It is widely used in medical diagnosis, pathological research, drug development, and biological education.
[0003] Before being examined by a tissue section scanner, the prepared slides need to be loaded by a four-axis robotic arm. The current loading mechanism mainly consists of a rotation, lifting, pushing and gripping mechanism. The existing rotation mechanism (also known as a rotary mechanism) uses a rotary ring, two stator bearings and one mover bearing. This structure is relatively large and suffers severe wear during rotation, requiring regular lubrication. Therefore, it is necessary to improve the existing stage rotation mechanism to solve the above problems. Utility Model Content
