[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a sample pick-and-place device for an ultra-high vacuum system, including a closed drive box 100. A separation clamp seat 101 is arranged on the bottom side of the closed drive box 100. Two movable grippers 102 are slidably installed on the bottom side of the separation clamp seat 101, and a sample tray 200 is held between the two movable grippers 102. A horizontal movable arm 400 is arranged on the top of the closed drive box 100, and a lifting arm 500 is arranged on the horizontal movable arm 400. By designing a specific structure for the movable grippers 102 and the sample tray 200, full cooperation and contact between the two are achieved, avoiding sample drop due to insufficient contact between the movable grippers 102 and the sample tray 200 during sample movement. At the same time, the detachable design of the closed drive box 100 and the separation clamp seat 101 allows for convenient disassembly and replacement of parts that are easily in contact with the sample, facilitating equipment maintenance and preventing cross-contamination between different samples.

[0025] In an optional embodiment: a compression rubber block 103 is fixedly installed on the bottom side of the movable gripper 102, and a fitting groove 201 is provided on the bottom side of the sample tray 200, and the compression rubber block 103 is adapted to the fitting groove 201.

[0026] It should be noted that the sample tray 200 is clamped by the movable gripper 102 and the extrusion rubber block 103. The extrusion rubber block 103 fits into the mating groove 201, making the clamping more stable and tight.

[0027] In an optional embodiment: a groove 104 is provided on the bottom side of the separation clamp seat 101, and a metal slider 105 is slidably installed in the groove 104. The metal slider 105 is fixedly installed on the top of the movable gripper 102.

[0028] It should be noted that the movable gripper 102 is restricted by the slide groove 104 and the metal slider 105, and can only move within a fixed range.

[0029] In an optional embodiment: a drive motor 300 is fixedly installed inside the enclosed drive box 100, a lead screw 301 is fixedly installed at the output end of the drive motor 300, two movable blocks 302 are threadedly installed on the lead screw 301, and an electromagnetic block 303 is fixedly installed on the bottom side of each of the two movable blocks 302. The two electromagnetic blocks 303 are respectively adapted to the metal slider 105.

[0030] It should be noted that the output end of the drive motor 300 drives the lead screw 301 to rotate. The rotating lead screw 301 drives the movable block 302 to move to a different position. The movable block 302 drives the electromagnetic block 303 to move, thereby achieving the effect of non-contact movement of the movable gripper 102 through the electromagnetic block 303.

[0031] In an optional embodiment: an upper connecting plate 106 is fixedly installed on the enclosed drive box 100, a lower connecting plate 107 is fixedly installed on the separation clamp seat 101, a bolt seat 108 is fixedly installed on the upper connecting plate 106, and an mounting bolt 109 is rotatably installed on the lower connecting plate 107, with the mounting bolt 109 threaded into the bolt seat 108.

[0032] It should be noted that when the equipment needs maintenance, the enclosed drive box 100 and the separation fixture seat 101 can be separated by the bolt seat 108 and the mounting bolt 109, thereby moving the separation fixture seat 101 and the movable gripper 102 to the outside of the experimental equipment for maintenance.

[0033] Example 2: In order to increase the range of motion of the device, a horizontal movable arm and a lifting arm are used to adjust the position in the horizontal and vertical directions, which further facilitates the handling of samples by the operator. The remaining features are the same as in Example 1.

[0034] In an optional embodiment: the horizontal movable arm 400 includes a movable arm housing 401, a linear module 402 is fixedly installed inside the movable arm housing 401, an electric slide table 403 is slidably installed on the bottom side of the linear module 402, and a closed drive box 100 is fixedly installed on the bottom side of the electric slide table 403.

[0035] It should be noted that horizontal movement requires the activation of the linear module 402 and the electric slide 403 to control the movement position of the enclosed drive box 100.

[0036] In an optional embodiment: the lifting arm 500 includes a lifting arm housing 501, a fixed frame 502 is fixedly installed inside the lifting arm housing 501, a movable frame 503 is slidably installed on the bottom side of the fixed frame 502, the movable frame 503 is fixedly installed on the movable arm housing 401, a lifting motor 504 is fixedly installed inside the fixed frame 502, a lifting screw 505 is fixedly installed at the output end of the lifting motor 504, a lifting slider 506 is threaded on the lifting screw 505, the lifting slider 506 is fixedly installed on the movable frame 503, and a sealing cover 507 is sleeved on the lifting arm housing 501.

[0037] It should be noted that in the vertical direction, the lifting motor 504 needs to be activated. The output end of the lifting motor 504 drives the movable frame 503 to move on the fixed frame 502 through the lifting screw 505 and the lifting slider 506, thereby controlling the horizontal movable arm 400 to move up and down.

[0038] The working principle is as follows: When using this device, the movable gripper 102 needs to be moved to the outside of the sample tray 200. Then, the drive motor 300 is started. The output end of the drive motor 300 drives the lead screw 301 to rotate. The rotating lead screw 301 drives the movable block 302 to move. The movable block 302 drives the electromagnetic block 303 to move, thereby achieving the effect of non-contact movement of the movable gripper 102 through the electromagnetic block 303. The movable gripper 102 and the extrusion rubber block 103 clamp the sample tray 200. The extrusion rubber block 103 fits into the mating groove 201, making the clamping more stable and tight. Horizontal movement requires starting the motor. The linear module 402 and the electric slide 403 control the movement position of the enclosed drive box 100. In the vertical direction, the lifting motor 504 needs to be activated. The output end of the lifting motor 504 drives the movable frame 503 to move on the fixed frame 502 through the lifting screw 505 and the lifting slider 506, thereby controlling the horizontal movable arm 400 to move up and down. After the experiment, the equipment needs to be maintained. The enclosed drive box 100 and the separation fixture seat 101 can be separated by the bolt seat 108 and the mounting bolt 109, so that the separation fixture seat 101 and the movable gripper 102 can be moved to the outside of the experimental equipment for maintenance.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
