Technical Field
[0001] This invention relates to the field of automatic tool changing system technology, specifically an expandable, storage-type automatic tool changing system. Background Technology
[0002] The warehouse-style automated tool changer uses a tool magazine as its core storage space, adaptable to disc or chain structures to meet the storage needs of tools of different sizes. The tool identification device uses an encoding verification mechanism to compare the system's preset tool information with the actual tool parameters being picked up, avoiding machining anomalies caused by tool loading errors. The tool-changing robot, as the execution unit, completes the disassembly of the old tool and the installation of the new tool according to the control system's instructions. Its servo drive structure ensures the accuracy and stability of the movements, reducing tool changing time. The control system relies on PLC programming and CNC technology to preset the tool changing sequence and action path, monitor the operating status of each component in real time, and synchronously record tool usage data to achieve lifespan management. This system can reduce the non-cutting time of manual tool changing, improve the machining efficiency of single-batch parts in machining centers, and adapt to the needs of multi-process continuous machining. Some high-end warehouse-style automated tool changers can complete a tool change operation in 4 to 6 seconds, further improving production continuity and reducing the probability of machining interruptions.
[0003] Traditional tool magazines typically employ disc or chain structures. While disc magazines offer controllable rotational inertia for smaller capacities, large-capacity disc magazines suffer from excessive rotational inertia, leading to positioning errors and collisions during start-up and shutdown. Chain magazines, despite their larger capacity, have numerous transmission links, causing accumulated errors to amplify over time. This can result in tool position misalignment and collisions during tool changes. Traditional tool change paths often rely on pre-set fixed trajectories without dynamic obstacle avoidance planning based on real-time operating conditions. When tools are worn or deformed, or when the spindle position shifts slightly, collisions between the tool and the magazine spindle are highly likely. Traditional posture transitions rely on mechanical hard stops for positioning; even minor displacements in the tool magazine or robotic arm can cause posture transition deviations, further increasing the risk of collisions. Collisions during storage and retrieval can directly cause tool chipping or spindle damage, significantly increasing equipment maintenance costs, extending downtime, and reducing production efficiency. Cumbersome posture transitions also increase the time required for a single tool change, slowing down the overall machining pace and diminishing the automation advantages of machining centers.
[0004] Therefore, the present invention provides an expandable storage-type automatic tool changer system with high-precision access and expansion adaptability. Summary of the Invention

[0016] The beneficial effects of this invention are: (1) The expandable storage automatic tool changer described in this invention solves the industry pain points of collision and cumbersome posture conversion of traditional tool magazines through a three-dimensional positioning system. The X-axis adopts a rack and pinion transmission structure and linear sliding with guide rail slider. The Y-axis adopts a screw and nut transmission mechanism to achieve precise entry and exit of tools. The longitudinal movement Z-axis is equipped with a servo screw lifting mechanism, which can stably support tool components of different weights. The flip plate is connected through the Z-axis frame and synchronously rotated with the reversing plate to achieve seamless conversion of the tool from horizontal posture to vertical posture.

[0017] (2) The expandable storage-type automatic tool changer described in this invention realizes unmanned operation of the entire tool change process. From the positioning of the new tool in the warehouse to the cleaning, drying and storage of the old tool, no manual intervention is required, which greatly reduces the proportion of auxiliary time in the workshop. The limiting part adopts an adaptive clamping mechanism driven by a cylinder, which can complete the alignment and limiting of the new tool before tool change, avoiding the spindle tool calibration error caused by tool center offset. The transverse part is equipped with a telescopic rod and a linear guide rail to realize the horizontal rapid movement of the inlet and outlet parts, accurately transferring the tool from the storage station to the exchange station, avoiding tool damage caused by manual handling. The cleaning part adopts a cleaning scheme that combines linkage rotary brushing and spray rinsing. The limiting threaded rod drives the cleaning cylinder to rotate synchronously through the gear set. The cleaning brush can cover the cutting edge and rod area of the tool in all directions. With the help of high-pressure spray cleaning agent and clean water, the high-temperature chips and oil stains remaining after cutting are thoroughly removed. The drying part is installed below the transverse part and completes the tool drying operation during the tool change interval without occupying additional production time.

[0021] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] Example: Figures 1-20As shown, the expandable storage-type automatic tool changing system of the present invention includes a tool magazine 1 and sample tools 11 disposed therein. A storage section 4 for positioning the sample tools 11 is provided inside the tool magazine 1. A transverse movement section 5 is provided on one side of the storage section 4. An inlet / outlet section 7 is provided at the top of the output end of the transverse movement section 5. A clamping clamp 3 for holding the sample tools 11 is provided at both the output end of the inlet / outlet section 7 and the inside of the tool magazine 1. An electric door 12 is fixed to one side of the tool magazine 1. A limiting member 8 is provided on one side of the electric door 12. A cleaning section 9 is connected to the bottom of the limiting member 8. A drying section 10 is provided at the bottom of the transverse movement section 5. The drying section 10 can be configured as a dryer, which is prior art. The storage section 4 includes an X-drive section 41 disposed at the top of the bottom wall of the tool magazine 1. A Y-drive section 43 is provided at the output end of the X-drive section 41. A Z-drive section 42 is provided at the output end of the Y-drive section 43. A flipping device is fixed to one side of the Z-drive section 42. The output end of the rotating plate 45 and the Z-drive unit 42 is rotatably connected to the clamp 44. When the Z-drive unit 42 drives the clamp 44 to move, it can rotate the clamp 44 by 90 degrees in conjunction with the flip plate 45. The X-drive unit 41, the Y-drive unit 43 and the Z-drive unit 42 can drive the clamp 44 to move to dock with the designated sample tool 11 inside the tool magazine 1 according to the principle of spatial coordinate system, and output the designated sample tool 11 to the inlet / outlet unit 7. The Y-drive unit 43 includes a Y motor 431. The Y motor 431 is fixed to the top of the Z-axis frame 424 through the connecting component. The side of the Z-axis frame 424 away from the Y threaded rod 432 is fixed with a Y guide rail 434. The output end of the Y motor 431 is connected to the Y threaded rod 432. The outside of the Y threaded rod 432 is engaged with the Y-axis frame 433. The Y-axis frame 433 is slidably locked to the outside of the Y guide rail 434. The flip plate 45 is fixed to the side of the Z-axis frame 424 away from the Z threaded rod 423 through the connecting component.
[0023] In this embodiment, as Figures 1-5 , Figures 7-12As shown, when the sample tool 11 is returned to the tool magazine 1 for storage, the operator controls the X motor 412 to rotate, causing the X-axis frame 415 to move to the X coordinate position corresponding to the designated sample tool 11, ensuring that the sample tool 11 does not collide with the fixed frame or support rod 2 during movement and rotation. Then, the operator controls the Z motor 422 to rotate, causing the Z-axis frame 424 to move along the Z guide rail 421 to the Z coordinate position corresponding to the designated sample tool 11. Then, the operator controls the Y motor 431 to rotate forward, and the output end of the Y motor 431 drives the Y thread rod 432 to rotate forward. The Y thread rod 432, through thread engagement with the Y-axis frame 433, causes the Y-axis frame 433 to move along the Y guide rail 434 towards the support rod 2. The Y-axis frame 433 drives the clamp 44 to move closer to the support rod 2. During this process, when the reversing plate 441 contacts the flipping plate 45, the reversing plate 441 rotates forward due to the reaction force given by the flipping plate 45. When the reversing plate 441 rotates ninety degrees, the other side of the reversing plate 441 is in contact with the flipping plate 45 and the bottom of the Z-axis frame 424. At this time, the axis of the bottom cavity 442 and the sample knife 11 changes from the Z-axis to the Y-axis. The Y motor 431 continues to rotate forward, and the sample knife 11 continues to move closer to the support rod 2. When the indentation on the outside of the sample knife 11 corresponds to the locking rod 33 of the fixed frame at the designated position, the X motor 412 is controlled to rotate, driving the sample knife 11 to move into the inside of the C-shaped plate 31. Then the sample knife 11 The clamping mechanism is secured by clamping plate 32 and three locking rods 33. Then, the operator controls the Y motor 431 to reverse, causing the output of the Y motor 431 to drive the Y threaded rod 432 to reverse as well. The Y threaded rod 432 engages with the Y-axis frame 433, causing the Y-axis frame 433 to move along the Y guide rail 434 away from the support rod 2. The Y-axis frame 433 then drives the clamping fixture 44 to move away from the support rod 2. During this process, as the bottom cavity 442 moves, the sample cutter 11 is restricted by the fixing frame. The sample cutter 11 compresses the side ball 449, causing the elastic element 2 to move into the inside of the side rod 448 and separate from the sample cutter 11. The sample cutter 11 then compresses the ball 447, which in turn pushes the pressure rod 443 to compress the elastic element. Simultaneously, the sample cutter 11 is separated from the bottom plate 446. Due to the action of the bottom plate 446, the pressure rod 443 prevents the ball 447 from falling off. After the sample cutter 11 is completely removed from the inside of the bottom cavity 442, the side ball 449 moves back to its original position under the action of the elastic element 2. Due to the restriction of the side rod 448, the side ball 449 will not fall off from the side rod 448. The pressure rod 443 squeezes the ball 447 to return to its original position under the action of the elastic element 444. When the reversing plate 441 contacts the flipping plate 45, the reversing plate 441 reverses due to the reaction force given by the flipping plate 45. When the reversing plate 441 rotates ninety degrees, the reversing plate 441 returns to its original position. At this time, the axial direction of the bottom cavity 442 returns to the Z direction, and the storage of the sample cutter 11 is completed.
[0024] Specifically, the X drive unit 41 includes an X guide rail 411, which is fixed to the top of the bottom wall of the tool magazine 1. A toothed plate 414 is fixed to the top of the bottom wall of the tool magazine 1. The toothed plate 414 is located on one side of the X guide rail 411. An X-axis bracket 415 is slidably mounted on the outer side of the X guide rail 411. An X motor 412 is fixed to the top of the X-axis bracket 415. An X gear 413 is fixed to the output end of the X motor 412. The X gear 413 meshes with the toothed plate 414 and is located at the bottom of the X-axis bracket 415.
[0025] In this embodiment, the operator controls the X motor 412 to rotate forward. The output end of the X motor 412 drives the X gear 413 to rotate forward. The X gear 413 drives the X-axis frame 415 to move along the outside of the X guide rail 411 towards the electric door 12 through meshing with the toothed plate 414. The X-axis frame 415 moves towards the electric door 12 by driving the components on its top and the clamp 44. The operator controls the X motor 412 to reverse, and the output end of the X motor 412 drives the X gear 413 to reverse. The X gear 413 drives the X-axis frame 415 to move away from the electric door 12 along the outside of the X guide rail 411 through meshing with the toothed plate 414. The X-axis frame 415 drives the components on its top and the clamp 44 to move away from the electric door 12.
[0026] Specifically, the Z drive unit 42 includes a Z guide rail 421. The bottom end of the Z guide rail 421 is fixed to the top of the X-axis frame 415. The top end of the Z guide rail 421 is fixedly connected to the tool magazine 1 through a connecting component. One end of the Z guide rail 421 is fixed with a Z motor 422 through a connecting component. The output end of the Z motor 422 is connected to a Z threaded rod 423. The outer side of the Z threaded rod 423 is threadedly engaged with a Z-axis frame 424. The Z-axis frame 424 is slidably engaged with the outer side of the Z guide rail 421.
[0027] In this embodiment, the operator controls the Z motor 422 to rotate forward. The output end of the Z motor 422 drives the Z thread rod 423 to rotate forward. The Z thread rod 423 drives the Z-axis frame 424 to move along the Z guide rail 421 towards the top of the tool magazine 1 through meshing. The Z-axis frame 424 moves towards the top of the tool magazine 1 by driving the components at its output end and the clamp 44. The operator controls the Z motor 422 to reverse, and the output end of the Z motor 422 drives the Z thread rod 423 to reverse. The Z thread rod 423 drives the Z guide 424 to move away from the top of the tool magazine 1 through meshing. The Z guide 424 drives the components at its output end and the fixture 44 to move away from the top of the tool magazine 1.
[0028] Specifically, the fixture 44 includes a reversing plate 441, which is rotatably connected to the side of the Y-axis frame 433 away from the Z-thread rod 423. A bottom cavity 442 is fixed to the bottom of the reversing plate 441, and a bottom plate 446 is fixed to the inner side of the bottom cavity 442. An elastic element 444 is fixed to the bottom of the top wall of the bottom plate 446, and a pressure rod 443 is fixed to the bottom of the elastic element 444. The pressure rod 443 is slidably connected to the inner side of the bottom plate 446. A ball bearing 447 is placed on the inner side of the bottom end of the bottom plate 446. The ball bearing 447 is arranged in a circumferential array about the axis of the pressure rod 443. A side rod 448 is fixed through the outer side of the bottom cavity 442, and an elastic element 2 is fixed to the inner side of the side rod 448. A side ball bearing 449 is fixed to the other end of the elastic element 2, and the side ball bearing 449 is slidably engaged with the inner side of the side rod 448.
[0029] In this embodiment, when the designated sample tool 11 needs to be removed, the operator first controls the X motor 412 to rotate, causing the X-axis frame 415 to move to the X coordinate position corresponding to the designated sample tool 11. Then, the operator controls the Z motor 422 to rotate, causing the Z-axis frame 424 to move along the Z guide rail 421 to the Z coordinate position corresponding to the designated sample tool 11. Next, the operator controls the Y motor 431 to rotate forward, and the output end of the Y motor 431 drives the Y thread rod 432 to rotate forward. Through the thread engagement with the Y-axis frame 433, the Y-axis frame 433 moves along the Y guide rail 434 towards the support rod 2, causing the clamp 44 to move towards the support rod 2. When the reversing plate 441 contacts the flipping plate 45, the reversing plate 441 rotates 90 degrees forward due to the reaction force given by the flipping plate 45, and the axis of the bottom cavity 442 changes from the Z direction to the Y direction. The Y motor 431 continues to rotate forward, and the clamp 44 continues to move towards the support rod 2. When the sample tool 11 is inserted into the inside of the bottom cavity 442... During the process, the sample cutter 11 first squeezes the side ball 449, which in turn squeezes the elastic element 2 and moves it into the inside of the side rod 448. The sample cutter 11 then squeezes the ball 447, which pushes the pressure rod 443 to squeeze the elastic element 1 444. After the sample cutter 11 is completely moved into the bottom cavity 442, the side ball 449 moves back to its original position under the action of the elastic element 2. The pressure rod 443, under the action of the elastic element 1 444, squeezes the ball 447 to return to its original position. The sample cutter 11 is then held by the clamp 44, and the X motor 412 is controlled to rotate. The rotating motion moves the sample cutter 11 out of the inner side of the C-shaped plate 31. Then, the Y motor 431 is controlled to reverse. The output end of the Y motor 431 drives the Y thread rod 432 to reverse, causing the Y-axis frame 433 to move along the Y guide rail 434 away from the support rod 2. This causes the clamp 44 and the sample cutter 11 to move away from the support rod 2. When the reversing plate 441 contacts the flipping plate 45, the reversing plate 441 drives the sample cutter 11 to reverse ninety degrees and return to its original position by relying on the reaction force given by the flipping plate 45.
[0030] Specifically, the limiting component 8 includes a limiting motor 81 located on one side of the electric door 12. The output end of the limiting motor 81 is connected to a limiting device 85 for clamping the sample knife 11. When waiting for a knife change, the limiting device 85 engages with the new sample knife 11 for alignment and limitation. After the knife change, the old sample knife 11 is moved into the cleaning section 9 for cleaning. The limiting motor 81 is fixed to the side of the electric door 12 near the storage section 4 via a connecting component. A limiting threaded rod 82 is fixed to the output end of the limiting motor 81. A limiting rail 86 is fixed to the side of the electric door 12 near the limiting motor 81. A limiting plate 84 is threadedly engaged with the outer side of the limiting threaded rod 82. A cylinder 83 is fixed to one side of the limiting plate 84. The output end of the cylinder 83 is fixed with the limiting device 85. The limiting device 85 has the same function as the bottom cavity 442, only with a different appearance. The limiting plate 84 is slidably engaged with the outer side of the limiting rail 86.
[0031] In this embodiment, the operator then controls the X motor 412, Y motor 431, and Z motor 422 to work together to move the removed sample knife 11 to the top of the telescopic rod 51 and match it with the fixing clamp 3 on the top of the bracket 72. Then, the operator controls the telescopic rod 51 to retract, causing the inlet / outlet part 7 to move closer to the clamp 44, so that the fixing clamp 3 on the top of the bracket 72 clamps the sample knife 11 inside the clamp 44. Then, the operator controls the Z motor 422 to rotate forward, releasing the clamp 44 from clamping the sample knife 11. Then, the operator controls the telescopic rod 51 to extend, causing the inlet / outlet part 7 to move closer to the limiting member 8, moving the sample knife 11 to the limiting member 8. 5. Ensure that the outer side of the sample knife 11 is aligned with the inner side of the limiting fixture 85. Then, control the limiting motor 81 to rotate forward. The limiting motor 81 drives the limiting threaded rod 82 to rotate forward. The limiting threaded rod 82 drives the limiting plate 84 to move along the outer side of the limiting rail 86 towards the bottom of the electric door 12 through meshing. The limiting plate 84 drives the cylinder 83 and the limiting fixture 85 to move towards the bottom of the electric door 12. When the part of the sample knife 11 at the top of the fixed frame enters the inner side of the limiting fixture 85, the limiting fixture 85 and the fixing clamp 3 simultaneously clamp the sample knife 11 to prevent the sample knife 11 from shifting or falling off due to equipment vibration or its own center problem during the static process.
[0032] Specifically, the transverse movement part 5 includes a corner plate 52, which is fixed to the inner wall of the side where the knife magazine 1 and the electric door 12 are connected, and is fixedly connected to the electric door 12.

The transverse movement rail 53 is located on one side of the telescopic rod 51. The drying part 10 is fixed to the inner side of the corner plate 52, and is located below the telescopic rod 51. Specifically, the inlet / outlet part 7 includes a rotary motor 71, which is slidably engaged with the transverse movement part 5 through a connecting component. Outside the transfer rail 53, the output end of the rotating motor 71 is fixed with a bracket 72. Specifically, the brackets are arranged in groups of two. Multiple support rods 2 are fixed inside the tool magazine 1. Multiple brackets are arranged on the back of the support rods 2. A bracket is arranged on the top of the bracket 72. Each bracket includes a C-shaped plate 31. The C-shaped plate 31 is fixed to one side of the support rod 2 or the top of the bracket 72. A clamping piece 32 is fixed on the outside of each C-shaped plate 31. A locking rod 33 is fixed on both ends and the inside of the opening of each C-shaped plate 31.
[0033] In this embodiment, when the sample knife 11 to be replaced arrives outside the electric door 12, the operator turns on the electric door and simultaneously controls the limiting motor 81 to reverse, causing the limiting device 85 to separate from the sample knife 11. The operator then controls the telescopic rod 51 to retract, and the telescopic rod 51 moves the bracket 72 to the center of the electric door 12. Then, the operator controls the rotating motor 71 to rotate 90 degrees clockwise, which in turn causes the bracket 72 to rotate 90 degrees clockwise. The bracket 72 moves its top empty fixing frame outside the electric door 12. Then, an external device places the sample knife 11 inside the empty fixing clamp 3 and separates it from the sample knife 11. Then, the operator controls the rotating motor 71 to rotate 180 degrees, moving the new sample knife 11 outside the electric door 12, where it is clamped and disassembled by an external device.
[0034] Specifically, the cleaning unit 9 includes a protective shell 91 fixedly connected to one side of the electric door 12. The bottom of the protective shell 91 is rotatably connected to the bottom end of the limiting threaded rod 82. A cleaning cylinder 93 is rotatably connected to the inside of the protective shell 91. The cleaning cylinder 93 and the bottom end of the limiting threaded rod 82 are connected by a gear set 92. A cleaning brush 94 is fixedly fixed to the inside of the cleaning cylinder 93. A drainage box 95 is sealed and rotatably connected to the outside of the cleaning cylinder 93. The drainage box 95 is fixedly connected to the protective shell 91. A cleaning agent channel 981 and a clean water channel 961 are opened through one side of the protective shell 91. The clean water channel 961 is located above the cleaning agent channel 981. The cleaning cylinder 93 has a water chamber 96 and a detergent chamber 98 inside. The water chamber 96 is located above the detergent chamber 98. A water hole 97 is opened through one side of the water chamber 96. A detergent hole 99 is opened on one side of the detergent chamber 98. The detergent hole 99 and the water hole 97 are arranged in a circular array about the axis of the cleaning cylinder 93. The flow box 95 connects the detergent channel 981 and the detergent chamber 98, and the water channel 961 and the water chamber 96, respectively. A right-angle tube 982 is fixed at the bottom of the cleaning cylinder 93. A cleaning plate 931 is fixed at the other end of all the right-angle tubes 982 that are close to each other. A brush is fixed at the top of the cleaning plate 931.
[0035] In this embodiment, after the blade replacement is completed, the electric door 12 is closed. Then, the operator controls the rotating motor 71 to rotate 90 degrees in reverse and controls the telescopic rod 51 to extend, placing the old sample blade 11 under the limiting device 85. The limiting motor 81 is controlled to rotate forward so that the limiting device 85 clamps the old sample blade 11. The telescopic rod 51 is controlled to retract so that the fixing clamp 3 at the top of the bracket 72 separates from the old sample blade 11. Then, the limiting motor 81 is controlled to continue rotating forward so that the limiting device 85 moves the old sample blade 11 into the cleaning cylinder 93. During this process, the bottom end of the limiting threaded rod 82 drives the cleaning cylinder 93 and the cleaning plate 931 to rotate through the gear set 92. As the old sample blade 11 moves downward, the cleaning brushes 94 inside the cleaning cylinder 93 and the cleaning plate 931 clean the old sample blade 11. At the same time, clean water and cleaning agent are supplied through an external liquid pump and pipeline (this is... (The existing technology will not be described in detail) The sample knife 11 is fed into the drainage box 95 through the clean water channel 961 and the cleaning agent channel 981, and then into the clean water chamber 96 and the cleaning agent chamber 98, respectively. Finally, it is sprayed out through the clean water hole 97 and the cleaning agent hole 99. With the help of the cleaning brush 94, the sample knife 11 is cleaned more thoroughly. After cleaning, the cleaning agent is stopped and only clean water is supplied. The sample knife 11 is rinsed during the upward movement of the sample knife 11. The number of cleaning and rinsing can be controlled by controlling the number of forward and reverse rotations of the limiting motor 81. After rinsing, the limiting motor 81 is reversed to restore the limiting device 85 to its original position. The telescopic rod 51 is extended and the fixed clamp 3 at the top of the bracket 72 holds the cleaned sample knife 11 and transports it to the storage unit 4. The storage unit 4 drives the sample knife 11 to be dried inside the drying unit 10 before storage.
[0036] Working principle: such as Figures 1-5 , Figures 7-12 As shown, when the sample tool 11 is returned to the tool magazine 1 for storage, the operator controls the X motor 412 to rotate, causing the X-axis frame 415 to move to the X coordinate position corresponding to the designated sample tool 11. Then, the operator controls the Z motor 422 to rotate, causing the Z-axis frame 424 to move along the Z guide rail 421 to the Z coordinate position corresponding to the designated sample tool 11. Then, the operator controls the Y motor 431 to rotate forward. The output end of the Y motor 431 drives the Y thread rod 432 to rotate forward, and the Y-axis frame 433 drives the clamp 44 to move closer to the support rod 2. During this process, the reversing plate 441 rotates forward due to the reaction force given by the flipping plate 45, the Y motor 431 continues to rotate forward, and the sample tool 11 continues to move closer to the support rod 2. When the outer side of the sample tool 11... After the indentation aligns with the locking rod 33 of the fixed frame at the designated position, the X motor 412 is controlled to rotate, driving the sample cutter 11 to move into the inner side of the C-shaped plate 31. Then, the sample cutter 11 is clamped by the clamping plate 32 and the three locking rods 33. Then, the operator controls the Y motor 431 to reverse, and the output end of the Y motor 431 drives the Y thread rod 432 to reverse. The Y thread rod 432, through the thread engagement with the Y guide frame 433, causes the Y guide frame 433 to move along the Y guide rail 434 away from the support rod 2. The Y guide frame 433 drives the clamp 44 to move away from the support rod 2. The reversing plate 441 flips by the reaction force given by the flipping plate 45. When the reversing plate 441 rotates ninety degrees, the reversing plate 441 returns to its original position. When the designated sample tool 11 needs to be removed, the operator first controls the X motor 412 to rotate, causing the X-axis frame 415 to move to the X coordinate position corresponding to the designated sample tool 11. Then, the operator controls the Z motor 422 to rotate, causing the Z-axis frame 424 to move along the Z guide rail 421 to the Z coordinate position corresponding to the designated sample tool 11. Next, the operator controls the Y motor 431 to rotate forward, and the output of the Y motor 431 drives the Y threaded rod 432 to rotate forward. Through threaded engagement with the Y-axis frame 433, the Y-axis frame 433 moves along the Y guide rail 434 towards the support rod 2, thus moving the clamp 44 towards the support rod 2. When the direction changes... When plate 441 contacts flip plate 45, reversing plate 441 rotates 90 degrees forward by the reaction force given by flip plate 45, Y motor 431 continues to rotate forward, and clamp 44 continues to move towards support rod 2. When sample knife 11 is inserted into the inner side of bottom cavity 442, sample knife 11 is clamped by clamp 44. Control X motor 412 to rotate and drive sample knife 11 to move out of the inner side of C-shaped plate 31. Then control Y motor 431 to reverse, clamp 44 and sample knife 11 move away from support rod 2. When reversing plate 441 contacts flip plate 45, reversing plate 441 drives sample knife 11 to reverse 90 degrees and return to its original position. Subsequently, the staff controlled the X motor 412, Y motor 431, and Z motor 422 to work together to move the removed sample knife 11 to the top of the telescopic rod 51 and match it with the fixing clamp 3 at the top of the bracket 72. Then, the staff controlled the telescopic rod 51 to retract, so that the fixing clamp 3 at the top of the bracket 72 clamped the sample knife 11 inside the clamp 44. Then, the staff controlled the Z motor 422 to rotate forward, releasing the clamp 44 from clamping the sample knife 11. Then, the staff controlled the telescopic rod 51 to extend, moving the sample knife 11 below the limiting fixture 85 and ensuring that the outer side of the sample knife 11 was aligned with the inner side of the limiting fixture 85. Then, the staff controlled the limiting motor 81 to rotate forward, so that the part of the sample knife 11 located at the top of the fixing frame entered the inner side of the limiting fixture 85. When the replacement sample blade 11 arrives outside the electric gate 12, the operator turns on the electric gate and simultaneously controls the limiting motor 81 to reverse, causing the limiting fixture 85 to separate from the sample blade 11. The operator then controls the telescopic rod 51 to retract and the rotating motor 71 to rotate 90 degrees clockwise. The rotating motor 71 drives the bracket 72 to rotate 90 degrees clockwise, moving the empty fixing bracket at its top outside the electric gate 12. Then, an external device places the sample blade 11 inside the empty fixing clamp 3 and separates it from the sample blade 11. The operator then controls the rotating motor 71 to rotate 180 degrees, moving the new sample blade 11 outside the electric gate 12, where an external device clamps and removes it. The operator then controls the rotating motor 71 to reverse 90 degrees and extends the telescopic rod 51, placing the old sample blade 11 below the limiting fixture 85. The operator then controls the limiting motor 81 to rotate clockwise, causing the limiting fixture 85 to clamp the old sample blade 11. The operator then controls the telescopic rod... 51 retraction causes the fixing clip 3 at the top of the bracket 72 to separate from the old sample knife 11. Then, the limiting motor 81 is controlled to continue rotating forward, causing the limiting device 85 to move the old sample knife 11 into the inner side of the cleaning cylinder 93. During this process, the bottom end of the limiting threaded rod 82 drives the cleaning cylinder 93 and the cleaning plate 931 to rotate through the gear set 92. As the old sample knife 11 moves down, the cleaning brush 94 fixed inside the cleaning cylinder 93 and at the top of the cleaning plate 931 cleans the old sample knife 11. At the same time, clean water and cleaning agent flow out through the clean water hole 97 and the cleaning agent hole 99, working together with the cleaning brush 94 to clean the sample knife 11. After cleaning, the cleaning agent is stopped, and only clean water is introduced. The sample knife 11 is rinsed during the upward movement of the sample knife 11. After rinsing, it is transported to the storage section 4, where the storage section 4 drives the sample knife 11 to be dried inside the drying section 10 before storage.
