[0046] In this embodiment, the bed 1 is rectangular, the X and Y directions are the length and width directions along the plane of the bed, the Z direction is the direction perpendicular to the plane of the bed, and the three directions of XYZ form a Cartesian coordinate system. The X-axis linear module 2, the Y-axis linear module 3, and the Z-axis linear module 4 are arranged along the three directions of X, Y, and Z, respectively, that is, the moving slides of the above three linear modules move linearly along the three directions of X, Y, and Z, respectively. The clamp 6 set on the X-axis linear module 2 is mainly used to fix the material to be cut, and the cutting head 9 is mainly used to install the cutting tool and drive the cutting tool to rotate.

[0047] In this embodiment, the Y-axis linear module 3 is mainly used for adjusting the front and rear feed of the cutting head 9, and the Z-axis linear module 4 is used for adjusting the up and down feed of the cutting head 9; the Z-axis rotary table 7 is mainly used to control and adjust the rotation angle of the Z-axis linear module (driving the cutting head); the cutting head rotary table 8 is mainly used to control and adjust the vertical and horizontal working angles of the cutting head. Both the Z-axis rotary table 7 and the cutting head rotary table 8 are rotated by an electric-controlled rotary table worm gear structure, and a motor is used to automatically control the rotation of the rotating part.

[0048] Since the Y-axis linear module 3 is provided with a Z-axis rotating table 7, and the Z-axis linear module 4 is provided on the Z-axis rotating table 7, the Z-axis linear module 4 can rotate around the Z-axis as a whole. Since the Z-axis linear module 4 is provided with a cutting head rotating table 8, and the cutting head 9 is provided on the cutting head rotating table 8, the cutting head 9 can rotate around the Y-axis as a whole. When in use, the sample material fixed on the clamp can be cut by the cutting disc knife 94, and at the same time, the Z-axis linear module 4 and the cutting head 9 can be rotated, and the drilling and milling cutter 95 can be replaced on the cutting head 9, so as to perform drilling and milling operations on the sample material fixed on the lifting drilling and milling table assembly 5.

[0049] According to some embodiments of the present application, the lifting drilling and milling table assembly 5 includes a drilling and milling table 51 and a lifting linear module 52, wherein the lifting linear module 52 is arranged on the bed 1 along the Z-axis direction, and the drilling and milling table 51 is arranged on the lifting linear module 52. The lifting linear module 52 is installed on an L-shaped mounting frame 53 arranged on the bed along the Z direction, and the moving slide of the lifting linear module 52 moves linearly along the Z direction. The drilling and milling table 51 is installed on the moving slide of the lifting linear module 52.

[0050] According to some embodiments of the present application, the drilling and milling table 51 includes a first pneumatic three-jaw chuck 512 and a rotary motor 513 arranged on a mounting bracket 511, the mounting bracket 511 is connected to the movable slide of the lifting linear module 52, the first pneumatic three-jaw chuck 512 is arranged along the Z-axis direction, and the rotary motor 513 drives the first pneumatic three-jaw chuck 512 to rotate through a transmission structure.

[0051] The transmission structure includes a driving gear, a driven gear and a rotary chain. The driving gear is mounted on the output shaft of the rotary motor 513, and the driven gear is mounted on the input shaft at the lower end of the first pneumatic three-jaw chuck 512. The driving gear and the driven gear are connected by a rotary chain transmission. The fixed part of the first pneumatic three-jaw chuck is fixedly connected to the mounting bracket through a positioning bracket, and the rotary part of the first pneumatic three-jaw chuck can rotate under the drive of the rotary motor.

[0052] According to some embodiments of the present application, an upper cutting disc 514 and a lower cutting disc 515 are respectively provided on the upper and lower parts of the first pneumatic three-jaw chuck 512. By providing the upper cutting disc and the lower cutting disc, it is possible to reduce the chips generated by drilling and milling from being scattered on the bed, and since it has a certain collection effect on the chips, it is helpful to reduce the cleaning work of the hot chamber.

[0053] When drilling and milling operations are required, the drilling and milling table is raised to a high position, the lower cutting disc 515 is placed under the drilling and milling table (in the opening of the bed), and the drilling and milling table is lowered to its original position; the first pneumatic three-jaw chuck 512 is opened, the sample material to be drilled and milled is clamped on the first pneumatic three-jaw chuck 512, and the upper cutting disc 514 is placed on the upper side of the first pneumatic three-jaw chuck 512. After the preparation is completed, the drilling and milling operation can be carried out; when the drilling and milling table chuck needs to rotate, the rotary motor is started to start the operation. After the drilling and milling is completed, the drilling and milling table is raised to a high position, and the lower cutting disc can be taken out.

[0054] According to some embodiments of the present application, the vise 6 includes a vise base 61, a vise main clamp 62 and a vise auxiliary clamp 63, the vise base 61 is connected to the X-axis linear module 2, and the vise main clamp 62 and the vise auxiliary clamp 63 are arranged at intervals along the moving direction of the vise base 61. By designing the vise into a double clamp mode, the sample is clamped and the cutting operation is performed between the vise main clamp and the vise auxiliary clamp, and the cut sample will not shake, which improves the safety of sample cutting and is also convenient for taking and placing and clamping the next material to be cut. The vise is suitable for clamping samples of different shapes: plate-shaped sample clamping, tube-rod-shaped sample clamping, and small plate sample clamping.

[0055] According to some embodiments of the present application, a chip receiving box 64 is provided in the interval area between the main clamp 62 and the auxiliary clamp 63. Since the material cutting position is between the main clamp and the auxiliary clamp, by placing the chip receiving box between the main clamp and the auxiliary clamp, the waste chips during sample cutting are completely collected in the chip receiving box, which is convenient for the collection and treatment of radioactive waste chips and reduces the difficulty of later decontamination of the hot chamber.

[0056] According to some embodiments of the present application, the X-axis linear module 2, the Y-axis linear module 3, the Z-axis linear module 4 and the lifting linear module 52 are all provided with a scale A6 along the moving direction, and a cursor pointer A7 is provided to indicate the displacement of the moving slide. In the event of a control system failure or damage to the dual-axis drive motor, the movement of the linear module can be manually controlled by the master-slave manipulator. Through the design of the cursor pointer and the scale, the movement of the equipment can be manually controlled in the event of a control system failure, and the staff can observe the position of the cursor pointer on the scale through the peep window to determine its movement displacement data.

[0057] Specifically, the above-mentioned linear module is a screw-type structure and is made of stainless steel. The linear module is mainly composed of a slide base A1, a drive screw A2, a double-track slide rail A3, a movable slide A4, a dual-axis drive motor A5 and other components. A gripper for the heating chamber manipulator to rotate is designed at the tail of the dual-axis drive motor so that the linear module can be manually driven to move by the manipulator. The linear module adopts a fully sealed cover design to prevent dust and chips in the air from falling into the drive screw during the operation of the equipment, affecting the operation accuracy of the equipment. It should be noted that the linear module is an existing mature product, and the design of the vernier pointer and the scale can be added according to the design improvement. Its working principle itself will not be explained.

[0058] The lead screw of the linear module adopts HIWIN series high-precision lead screw, and the transmission lead screw of the entire device adopts C2 grade transmission lead screw, with a single lead change of 0.004mm and an arbitrary 300mm lead change of 0.006mm; the ball screw and the lead screw nut structure are used in conjunction with each other, with linear feed and high transmission efficiency. The guide rails all adopt HG series high-precision guide rails, which are four-row single arc tooth contact linear guide rails. Compared with other linear guide rails, they have improved load and rigidity capabilities; they have four-direction load characteristics and automatic self-aligning functions, which can absorb the assembly error of the installation surface and meet high-precision requirements.

[0059] According to some embodiments of the present application, the cutting head 9 includes a second pneumatic three-jaw chuck 92 and a drive motor 93 arranged on a cutting bracket 91, the cutting bracket 91 is connected to the cutting head rotating table 8, the second pneumatic three-jaw chuck 92 is used to clamp the cutting tool, and the drive motor 93 is used to drive the cutting tool to rotate.

[0060] The main function of the cutting head 9 is to clamp the cutting tool and drive the cutting tool to rotate. The connection method between the second pneumatic three-jaw chuck and the drive motor complies with the national standard (short cylindrical connection form). It can be installed by only equipping a connecting flange that matches the second pneumatic three-jaw chuck, and the installation is very convenient. The pneumatic three-jaw chuck body is a cylinder with a built-in piston and a check valve. It has an ultra-long pressure-maintaining function (up to 24 hours or more). It rotates the side to intake air to achieve clamping and loosening actions. It can only work when the air source is disconnected. The pneumatic three-jaw chuck has the advantages of light weight, large aperture, large stroke, and high speed. The cutting head drive motor can use a domestic stepping motor.

[0061] According to some embodiments of the present application, the cutting tool includes a cutting disc 94 and a drilling and milling cutter 95. The cutting disc 94 is mainly used for cutting operations of materials, while the drilling and milling cutter 95 is mainly used for drilling and milling operations on materials. When drilling and milling are required, the drilling and milling cutter 95 can be exchanged with the cutting disc 94. The main part of the cutting disc is in the shape of a disc, and a round rod-shaped shank is provided in the center of the cutting disc, and the shank part of the drilling and milling cutter is also in the shape of a round rod. This design facilitates the installation and clamping of the cutting disc and the drilling and milling cutter on the pneumatic three-jaw chuck, and facilitates the hot chamber manipulator to change the tool according to processing needs.

[0062] The cutting tool chuck adopts a pneumatic three-jaw chuck structure design that is easy to disassemble quickly, making it convenient for the robot to disassemble and change the tool; different sizes of saw blades and milling cutters can be used for cutting large samples and small samples. At this time, the original tool for cutting large samples is replaced with a tool suitable for cutting small samples or a drilling and milling tool. When changing the tool, open the pneumatic three-jaw chuck, install the tool with the milling cutter and tool rod assembly firmly combined into a safe position on the pneumatic three-jaw chuck, close the pneumatic three-jaw chuck, and lock the tool.

[0063] According to some embodiments of the present application, the bed 1 includes a mounting base plate 11 and a driving structure, the X-axis linear module 2, the Y-axis linear module 3, the Z-axis linear module 4 and the lifting drilling and milling table assembly 5 are all arranged on the upper side of the mounting base plate 11, and the driving structure is used to drive the mounting base plate 11 to move linearly along the Y-axis direction. With the above design, the mounting base plate and the components mounted thereon can be moved as a whole to a specified position by the driving structure when not in operation, and reset when the material needs to be cut, so that the moving position is conducive to improving the utilization rate of the hot chamber space.

[0064] According to some embodiments of the present application, a lifting platform 12 is provided below the bed 1, and the driving structure is provided between the lifting platform 12 and the mounting base 11. The lifting platform can be a scissor-type electric lifting platform, which is used for the overall lifting of the bed, and the height of the bed can be adjusted according to the cutting object.

[0065] The lifting platform 12 mainly includes a lift chassis 121, a scissor frame 122, a lift platform 123, a sliding shaft 124, an electric push rod 125, etc. Among them, the lift chassis, as the supporting foundation of the entire equipment, can be fixedly connected to the ground in the hot room, the sliding shaft is arranged on the lift chassis, and the lower end of the scissor frame is hinged to the lift chassis and forms a sliding connection with the sliding shaft, the electric push rod body is connected to the lift chassis, and the output end of the electric push rod is connected to the scissor frame. The two scissor arms of the scissor frame can be pushed to rotate relative to each other through the extension and retraction of the electric push rod, so that the angle between the two scissor arms changes, and then the height of the lift platform relative to the lift chassis changes, thereby realizing the height adjustment of the bed body.

[0066] The driving structure between the lifting platform and the mounting substrate in this embodiment mainly includes a moving motor 13, a moving rack 14, a track 15, a track wheel 16, a positioner, a limiter, etc. The moving rack 14 and the track are arranged along the Y direction, wherein the moving rack 14 is fixedly arranged on the lower side of the mounting substrate 11, the track 15 is fixedly arranged on the surface of the lifting platform 123, and the track wheel 16 is rollingly installed between the moving rack 14 and the track 15. When the bed position needs to be moved, the moving motor drives the moving rack to move along the Y direction through the gear, and then drives the track wheel to move along the track, thereby driving the mounting substrate to move. The positioner and the limiter are mainly used to limit the extreme position of the mounting substrate when it moves along the Y direction and the position when it is reset. It should be noted that the above-mentioned driving structure can be set as one group or multiple groups as needed.

[0067] In this embodiment, a dust cover is arranged around the mounting base 11 and the lifting platform 123. The dust cover is a ring-shaped thin plate structure. The upper end of the dust cover is connected to the mounting base around and can move with the mounting base. The dust cover surrounds the mounting base and the lifting platform around, which can prevent dust from entering the bed.

[0068] According to some embodiments of the present application, a polishing machine 17 is provided on the bed 1 for burr treatment after sample cutting. By providing the polishing machine, the cut sample can be clamped by a manipulator in the hot chamber to grind and remove the burrs on the edge of the sample.

[0069] According to some embodiments of the present application, the motors of the X-axis linear module, Y-axis linear module, Z-axis linear module, lifting linear module, as well as the cutting head drive motor and the drilling and milling table rotary motor all use shielding covers made of stainless steel, namely the X-axis linear module motor shielding cover, the Y-axis linear module motor shielding cover, the Z-axis linear module motor shielding cover, the cutting head rotating axis motor shielding cover, the cutting head drive motor shielding cover, the drilling and milling table rotary motor shielding cover, etc.

[0070] According to some embodiments of the present application, the sample preparation device further includes a control system for controlling the operation of the sample preparation device. The control system is composed of a main control cabinet, a cantilever control box, a wall-mounted video display, and actuators such as sensors on the device. The layout scheme is comprehensively considered based on the structural characteristics of the hot chamber, the spatial layout, and the convenience of operation and maintenance.

[0071] The main control cabinet in this embodiment integrates most of the low-voltage components, controllers and drivers, etc., and is the main switch of the control system. The control cabinet is placed separately near the peep window in the front area of ​​the hot chamber, without interfering with the placement and operation of other items, while ensuring the maintenance space and convenient operation of the main control cabinet.

[0072] The cantilever control box in this embodiment is the main operation interface. With the convenience of operation as the primary principle, the cantilever control box is installed on the wall near the peep window. In normal use, the cantilever control box can be dragged in front of the peep window to observe the status of the equipment inside the hot chamber through the peep window during operation; when the equipment is not operated, the cantilever control box can be rotated to the side without affecting the use of the peep window and other equipment.

[0073] The wall-mounted display in this embodiment is an interface for displaying the video surveillance screen in the hot chamber. The video surveillance screen may be needed to assist in operating the remote control cutting system, so the wall-mounted display is installed near the cantilever control box for easy observation by the operator. Sensors and other actuators are installed on the main equipment of the remote control cutting system.
