Description

Technical Field

[0001] The utility model relates to the technical field of microscope inspection, in particular to a lifting motion device and a microscope inspection analyzer. Background Art

[0002] At present, most microscopes are cumbersome to operate, large in size, and inconvenient to carry around, making it difficult to achieve real-time detection. The document with Chinese patent publication number CN220855329U discloses an anti-leakage detection microscope analyzer, which includes: a microscope component, a slide placement table, a three-dimensional motion component, an automatic dripping and waste oil recovery component, a control component, and a bottom plate. The instrument has a small structure and is compact as a whole. It can realize automatic scanning and imaging of samples through a three-dimensional motion mechanism and a microscope component. Figure 1 The consistency and accuracy are high, and the missed detection and false detection rates are low. However, the Z-axis motion mechanism of the three-dimensional motion mechanism of the device adopts a gear rack mechanism. During the actual movement of the device, if the load on the up and down lifting is too large, the gear rack mechanism will fall rapidly after the power is cut off, causing abnormal noise and failure of the device. At the same time, a large load will be generated on the motor during the movement of the mechanism. Therefore, it is particularly important to develop a lifting motion device and microscope analyzer with a compact structure that can reduce the load on the motor and avoid the rapid descent of the lifting platform when the power is cut off.
