Electron microscope sample multifunctional ultrathin trimming device

Abstract

The invention discloses an electron microscope sample multifunctional ultrathin trimming device. The electron microscope sample multifunctional ultrathin trimming device comprises an electron microscope and a microtome, wherein the microtome comprises a base, a sample clamping head and a blade clamping head, wherein the sample clamping head and the blade clamping head are arranged on the base; theblade clamping head is provided with a blade, and the base is further provided with a rough trimming mechanism; the rough trimming mechanism comprises a driving motor, a reversing gear set, two grinding wheels and grinding wheel adjusting pieces, wherein the two grinding wheels are arranged in the opposite directions; the driving motor drives the grinding wheels to rotate by driving the reversinggear set to move; and the grinding wheel adjusting pieces are used for adjusting the distance between the two grinding wheels, the reversing gear set comprises a first output spur gear and a second output spur gear, and rotating shafts of the two grinding wheels are correspondingly installed on gear shafts of the first output spur gear and the second output spur gear through couplings. The electron microscope sample multifunctional ultrathin trimming device integrates four processes of grinding, rough trimming, fine trimming and slicing into a whole, rough grinding, fine trimming and slicingcan be operated on one machine without dispersing process operations, and thus the efficiency in actual work is higher.

Description

technical field [0001] The invention relates to the technical field of epoxy resin sample slicing, in particular to a multifunctional ultra-thin trimming device for electron microscope samples. Background technique [0002] At present, the ultra-thin samples of the electron microscope are processed in batches. After the samples are embedded in epoxy resin, they need to undergo rough trimming with a trimming machine, fine trimming with a manual blade, and slicing with a microtome. Different processes require different procedures. processed on the machine. For example, the Leica EM UC7 ultra-thin microtome produced by Leica is mainly used for fine-tuned ultra-thin slices, and the Leica EM RAPID multifunctional trimming machine is mainly used for rough trimming, and the fine trimming still relies on manual work sometimes. The refinishing operation is performed on the UC7 ultramicrotome. The entire operation process needs to be replaced, which takes a long time, resulting in lo...

Problems solved by technology

For example, the Leica EM UC7 ultra-thin microtome produced by Leica is mainly used for fine-tuned ultra-thin slices, and the Leica EM RAPID multifunctional trimming machine is mainly used for rough trimming, and the fine trimming still relies on manual work sometimes. The refinishing operation is performed on the UC7 ultramicrotome. The entire operation process needs to be replaced, which takes a long time, resulting in low efficiency of the entire section, which is not conducive to batch operations.

Although rough trimming can also be achieved on the UC7 instrument, the operation is more cumbersome and requires frequent replacement of the base, trimming knife and trimming accessories, which takes a long time. In addition to frequent replacement of accessories, the base of the UC7 instrument will be damaged after a long period of use. Abrasion also brings certain errors to ultra-thin sections
