Description

Technical Field

[0001] The utility model relates to the technical field of slicing, in particular to a slicing rack. Background Art

[0002] When performing microscopic imaging and digital slice scanning, most scanning devices do not support directly inserting a single glass slice into the scanning device for scanning. Most scanner manufacturers' approach is to first load a single or multiple slices into a slicing rack, and then insert or load the slicing rack together with the slices into the scanning device for scanning. The purpose of doing this is, on the one hand, that a single slice does not have any features suitable for automated operation, and it is not easy to achieve automatic feeding and discharging of the slices, which will affect the efficiency of the scanning device; on the other hand, glass is fragile, and directly operating the slice is likely to damage the slice during the operation and even injure the operator. Thus, the slicing rack has become an important accessory for many scanning devices.

[0003] The existing integrally formed plastic slicing rack can have various capacity specifications for one slice or multiple slices, and the slicing rack is provided with one or more elastic claw structures in three directions of X, Y, and Z. Usually, the clamping and holding of the slice are achieved by the material properties of the slicing rack itself and the elastic deformation of the elastic structure. However, the elastic deformation amount of the plastic material and the elastic structure is limited. Therefore, there are limitations on the size of the glass slice. There is a problem that too large slices cannot be loaded, and too small slices may not be able to be clamped tightly, and all slices within the same specification standard range cannot be adapted. And to ensure the elastic force of the elastic claw, the elastic claw is usually designed with a slender root structure. This structure is prone to injection molding defects due to poor material flow during molding, resulting in the slicing rack being prone to breakage at this position, significantly shortening the service life of the slicing rack.
