Technical Field

[0001] The present invention relates to the field of vacuum instruments and equipment, in particular to a flat sample rack expansion structure for vacuum use. Background Art

[0002] In commonly used ultra-high vacuum measurement equipment, flat sample holders (holders) are often used to fix the sample and then transfer it into the equipment for measurement. The sample heating tables and rotating tables of many measurement equipment are also designed and manufactured based on flat sample holders. Flat sample holders take up little space and have a small heat capacity, which is very convenient for use in low-temperature equipment, such as ARPES and MBE. However, the measurement device of one type of vacuum low-temperature and high-magnetic field equipment is located in a low-temperature dewar. The flat sample holder cannot be smoothly transferred to the measurement position. Therefore, a cylindrical sample holder is often used to fix the sample and then insert it into the measurement position. Therefore, it is difficult to unify the equipment using the above two types of sample holders to build a vacuum measurement platform. Summary of the Invention

[0045] See also Figures 1 to 4 A vacuum flat sample holder expansion structure includes an adapter 100 and a flat sample holder tray 200. The adapter 100 is detachably fixedly connected to the flat sample holder tray 200. A space for fixing a flat sample holder 300 is defined between the adapter 100 and the flat sample holder tray 200. The flat sample holder 300 is detachably fixed within the space. The adapter 100 is detachably connected to a cylindrical sample holder gripper 400. The cylindrical sample holder gripper 400 can be detachably connected to the adapter 100 to grab the adapter 100 and move the flat sample holder 300.

[0046] Optionally, the accommodating space may be formed by the flat sample rack tray 200 alone, or may be formed by the adapter 100 and the flat sample rack tray 200 together, as long as the space can accommodate the flat sample rack 300 .

[0047] See also Figure 1 、 Figure 2 and Figure 6In one embodiment, the vacuum flat sample holder expansion structure further includes a fastening element 500. The flat sample holder tray 200 has an opening for mounting and accommodating the flat sample holder 300. Specifically, the accommodating space is formed by the opening of the flat sample holder tray 200. The sidewalls of the opening are provided with a stepped surface 210 capable of supporting the flat sample holder 300. The stepped surface matches the contour of the flat sample holder 300 to support and position the flat sample holder 300. A flat sample holder gripper 600 is capable of mounting or removing the flat sample holder 300 from the stepped surface 210. The adapter 100 is approximately I-shaped, with a through hole in the center of the I-shaped structure. The through hole extends through the head, neck, and tail of the I-shaped adapter 100. After the flat sample holder 300 is mounted on the step surface 210 , the fastening element 500 passes through the through hole and abuts against the flat sample holder 300 . Under the combined action of the step surface 210 and the fastening element 500 , the flat sample holder 300 is fixed in the adapter 100 .

[0048] Optionally, the fastening element 500 is a fastening screw, and the through hole is a threaded hole. After the flat sample rack 300 is placed on the stepped surface 210, the fastening screw is screwed into the threaded hole so that the end of the fastening screw abuts against the upper surface of the flat sample rack 300, thereby fixing the flat sample rack 300 between the adapter 100 and the flat sample rack tray 200. The cylindrical sample rack gripper 400 grasps the adapter 100 to transfer the flat sample rack 300.

[0049] See also Figure 1 and Figure 2 In one embodiment, the I-shaped structure includes a head 110, a neck 120, and a tail 130, wherein the head 110 and the tail 130 are respectively fixedly connected to the ends of the neck 120. The head 110 is disc-shaped, and a protrusion 111 is distributed on the outer wall of the disc-shaped head 110. The cylindrical sample holder gripper 400 is detachably connected to the adapter 100 by grasping the protrusion 111.

[0050] Optionally, the number of the protruding rods 111 is three, and the three protruding rods 111 are evenly distributed on the outer wall of the disc-shaped head 110. The cylindrical sample rack gripper 400 has a gripper buckle position corresponding to the protruding rod 111, and the gripper buckle position includes an insertion portion and a fastening portion. After the protruding rod 111 enters the insertion portion, the cylindrical sample rack gripper 400 is rotated to make the protruding rod 111 enter the fastening portion. After the fastening portion fastens the protruding rod 111, the cylindrical sample rack gripper 400 grabs the adapter 100 and moves.

[0051] See also Figure 1 In one embodiment, the tail portion 130 of the I-shaped structure is cylindrical, and the top wall of the cylindrical tail portion 130 is fixedly connected to the head portion 110 through the neck portion 120 of the I-shaped structure. Threaded holes for connecting to the flat sample rack tray 200 are uniformly distributed on the side walls of the cylindrical tail portion 130. The flat sample rack tray 200 also has threaded holes at corresponding positions. The flat sample rack tray 200 is threadedly fixedly connected to the cylindrical tail portion 130.

[0052] See also Figure 2 、 Figure 4 and Figure 5 In one embodiment, an outwardly extending latch 131 is provided on the top wall of the tail portion 130, and the cylindrical sample holder holder 700 is detachably connected to the adapter 100 via the latch 131. The cylindrical sample holder holder 700 is provided with a slot, and the latch 131 is engaged with the slot to securely connect the adapter 100 to the cylindrical sample holder holder 700.

[0053] Optionally, there are three latches 131, which are evenly distributed on the outer wall of the cylindrical tail portion 130. In the vertical direction, the three protruding rods 111 are arranged parallel to the three latches 131. Specifically, the cylindrical sample rack gripper 400 grasps the three protruding rods 111, installs the adapter 100 carrying the flat sample rack 300 and the flat sample rack tray 200 on the cylindrical sample rack holder 700, and secures them by snapping the three latches 131 into the slots of the cylindrical sample rack holder 700.

[0054] See also Figure 2In one embodiment, a notch 132 is formed on the sidewall of the tail portion 130 at a position corresponding to the opening of the flat sample rack tray 200. The notch 132 can accommodate the front end of a flat sample rack gripper 600. The flat sample rack gripper 600 extends into the notch 132 to install and remove the flat sample rack 300. When the flat sample rack gripper 600 installs the flat sample rack 300 on the stepped surface 210, the notch 132 provides a clearance for the flat sample rack gripper 600, facilitating its installation on the stepped surface 210. The flat sample rack gripper 600 then extends into the notch 132 to remove the flat sample rack 300.

[0055] In one embodiment, the adapter 100 and the flat sample holder tray 200 are made of non-magnetic materials with good thermal conductivity.

[0056] See also Figures 1 to 6 The operation process of transferring the flat sample holder 300 using the cylindrical sample holder gripper 400 is as follows:

The flat sample rack gripper 600 installs the flat sample rack 300 into the storage space. The fastening element 500 locks the flat sample rack 300. The cylindrical sample rack gripper 400 grabs the head 110 of the adapter 100 and adjusts the position and angle. The adapter 100 is installed on the cylindrical sample rack holder 700 and is clamped by the tail 130 of the adapter 100.

[0058] The above-mentioned vacuum flat sample holder expansion structure is detachably connected to the flat sample holder tray 200 via an adapter 100. A space for a flat sample holder 300 is defined between the adapter 100 and the tray 200. The flat sample holder 300 is detachably secured within the space, and a cylindrical sample holder gripper 400 is detachably connected to the adapter 100. This allows the cylindrical sample holder gripper 400 to transfer the flat sample holder 300 and its sample into a low-temperature, high-magnetic-field apparatus for sample exchange in a vacuum environment, providing a key technical solution for a multi-instrument integrated platform.
