Embodiment
Based on embodiment, present invention is described below, but the present invention is not restricted to these embodiments.In hereafter details of the present invention being described, detailedly describe some specific detail sections.Do not have the description of these detail sections can understand the present invention completely for a person skilled in the art yet.In order to avoid obscuring essence of the present invention, known structure, method do not describe in detail.
Support frame positioning device in the present embodiment, shown in Figure 1, comprise the first holding piece 1, second holding piece 2 and support 6.Support 6 is arranged between two holding pieces, is located between holding piece and support by elastic positioning device and the locating slot that matches with elastic positioning device.
Preferably, support 6 is scanning tunnel microscope (STM), and the advanced scientific research apparatus such as angle resolved photoelectron spectroscope instrument (ARPES) can use specimen holder usually, is used for fixing the required sample measured.Sample is arranged on the front of specimen holder, and elastic positioning device is arranged between the back side of specimen holder and holding piece, see Fig. 3.
In the present embodiment, what elastic positioning device adopted is elastic device and place kick 4, and what elastic device adopted in the present embodiment is shell fragment 3, and wherein shell fragment is arranged on the first holding piece, and place kick is connected with the first holding piece by shell fragment.The quantity of place kick is at least two, is preferably 3, can realize accurately and reliably locating, and prevents specimen holder from moving relative to holding piece.Shell fragment can adopt multiple place kick to share the structure of, as shown in this embodiment, the shaped as frame that shell fragment 3 is orthogonal, three place kick are arranged on the shell fragment of shaped as frame; In addition, also can adopt each place kick that the structure of a flexure strip is set.Except shell fragment, elastic component can also adopt spring or other elastic constructions and their combination.
Be threaded connection part between two holding pieces to be connected, the clamping force between holding piece can be regulated by adjustment threaded connector, the relative position between shell fragment and the first holding piece can also be regulated, and then regulate shell fragment to the elastic force of place kick and specimen holder, finally realize the dual purpose of specimen holder location and clamping.Shell fragment can adopt fixing mode to be arranged on holding piece, the mode of position-adjustable also can be adopted to be arranged on holding piece, thus can regulate the relative position of specimen holder and holding piece.
Preferably, holding piece is provided with orientation room's (not shown), shell fragment and place kick are arranged in orientation room, orientation room is provided with opening in the face of specimen holder side, described A/F is less than the diameter of place kick, can prevent place kick from deviating from from orientation room, place kick is exposed in the outside of orientation room at least partially for matching with the spherical groove of specimen holder.Shell fragment is used for applying elastic force to place kick to the direction being exposed to described orientation room opening.Independently orientation room can be set respectively for each place kick, also whole place kick can be arranged in an orientation room.Orientation room can be projecting from holding piece; Also can be embedded into the inside of holding piece, keep the level and smooth of holding piece surface, now observe from outside, a part for place kick is only had to protrude from the surface of holding piece, like this can when holding piece accommodates specimen holder, reduce the interference that projection causes, clamping more accurately and firm.
Position corresponding with place kick arrangement position on specimen holder, is provided with multiple locating slot, is spherical groove 5 in the present embodiment, and see Fig. 2, the profile of spherical groove and the surface configuration of place kick match.When specimen holder is fixed in holding piece, specimen holder promotes place kick, place kick compression shell fragment, and when sample rack moving is to correct position, under the elastic force effect of shell fragment, place kick embeds in spherical groove and then realizes the accurate location of specimen holder.
In addition, can also adopt, be arranged on specimen holder by shell fragment and place kick, spherical groove is arranged on the mode on certain holding piece, also can realize the accurate location of specimen holder.Preferably, aforesaid orientation room is arranged on specimen holder in order to hold place kick and elastic component.
In addition, place kick can adopt conductive material to make, use as electrode, specimen holder adopts insulating material to make, and place kick one end is by wire 8 connecting test instrument (not shown), the other end is connected with sample through specimen holder by wire 9, as shown in Figure 3, like this after sample grows up to, do not need sample to take out from specimen holder, directly can realize the measurement to sample by support frame positioning device, the while of measuring more convenient, also not affect the accurate location to sample.
In addition, locating slot can also adopt the structure of elongated slot, be preferably straight-line groove, arc groove or their combination, being formed place kick of groove two side and elastic component is spacing, thus the location achieved place kick two dimensions, place kick is restricted to move along elongated slot, so that regulate the relative position of specimen holder and holding piece.
