Description

Technical Field

[0001] This application relates to the field of tool changing equipment, and in particular to an automatic louver changing device. Background Technology

[0002] In automated production lines, achieving rapid and accurate replacement of consumables is crucial for improving production efficiency and processing quality. Various quick-change tool changers for robot end effectors (such as spindles) already exist. These devices typically achieve physical connection and separation between tools based on a rigid locking structure of a mechanical interface, such as through chucks, pin engagement, or hydraulic / pneumatic locking.

[0003] While such devices enable rapid tool switching to some extent, in practical applications, especially in scenarios where it is necessary to frequently change grinding consumables of different specifications (such as grinding wheels of different diameters, louvers of different sizes and grits), existing quick-change devices are limited by their internal space. The quick-change device can only store a small amount of grinding consumables in advance, and the equipment needs to be stopped to replenish them when the consumables are used up. This reduces the efficiency of consumable replacement and affects the production schedule. Utility Model Content

[0004] Therefore, it is necessary to provide an automatic replacement device for louvers to address the problem that existing quick-change technologies are limited by internal space and can only store a small amount of consumables, resulting in the need for multiple shutdowns to replenish consumables during equipment operation and affecting replacement efficiency.

[0005] This application provides an automatic louver replacement device, which adopts the following technical solution:

[0006] An automatic louver replacement device includes a frame and a pushing assembly. The frame has an operating platform and a consumables storage compartment for storing new louver blades. The consumables storage compartment extends through the operating platform along a first direction to form a storage opening. The pushing assembly is disposed within the consumables storage compartment and is used to move the new louver blade along the first direction until the new louver blade protrudes from the storage opening. The pushing assembly includes a support member and a pushing drive member. The support member supports the new louver blade, and the pushing drive member is throttle-connected to the support member to drive the support member to move along the first direction. The pushing drive member includes a cylinder, a piston disposed within the cylinder, and a slider magnetically coupled to the piston. The slider is throttle-connected to the support member. The cylinder extends along the first direction and is connected between the top and bottom walls of the consumables storage compartment. The support member can move synchronously along the first direction with the piston and the slider. The first direction is defined as a direction perpendicular to the operating platform.

[0007] In one embodiment, the pushing assembly further includes a positioning member and a positioning drive member. The positioning member passes through the support member and can be disposed in the mounting hole of the louver. The positioning drive member is tractively connected to the positioning member to drive the positioning member to move along the first direction.

[0008] In one embodiment, the pushing assembly further includes a guide platform and a guide rod. The guide platform is arranged parallel to the operating platform and is connected to the support and / or the positioning member. The guide rod passes through the guide platform along the first direction and is fixed to the frame. The guide platform is slidably connected to the guide platform.

[0009] In one embodiment, the pushing drive further includes a linear bearing fitted into the guide platform along the first direction, and the guide rod is capable of passing through the inner hole of the linear bearing along the first direction.

[0010] In one embodiment, the pushing assembly further includes a dust cover that is fitted around the periphery of the cylinder and can be connected to the slider to seal the connection gap between the slider and the cylinder.

[0011] In one embodiment, the automatic replacement device further includes a loading / unloading assembly and a control assembly. The loading / unloading assembly is mounted on the frame and spaced apart from the chute opening along a second direction. The loading / unloading assembly is used to assemble new louvers onto the main shaft or to remove old louvers from the main shaft. The control assembly includes a sensing element and a control module. The sensing element is mounted on the operating platform and is used to sense whether the chute opening has louvers. The control module is signal-connected to the sensing element and can control the movement of the pushing assembly based on the signal fed back by the sensing element. The second direction is perpendicular to the first direction.

[0012] In one embodiment, the automatic replacement device further includes a spacer component installed on the operating platform, the spacer component being signal-connected to the control module, and the spacer component being able to open or close the storage port according to the signal fed back by the sensing element.

[0013] In one embodiment, the loading and unloading assembly includes a loading and unloading wrench and a wrench drive, the loading and unloading wrench being used to load and unload the fixing nut of the louver, and the wrench drive being throttle connected to the loading and unloading wrench and driving the loading and unloading wrench to move along the first direction.

[0014] In one embodiment, the loading and unloading assembly further includes a clamping member mounted on the frame, the clamping member being used to clamp the spindle to restrict the rotation of the spindle, and the clamping member and the operating platform forming a clearance area for accommodating the louvers.

[0015] In one embodiment, the clamping member has a bayonet that can penetrate the end face of the clamping member facing the opening in the second direction, so that the spindle can move into the bayonet in the second direction, and the inner wall of the bayonet can fit against the edge of the spindle; wherein the cross-sectional shape of the bayonet is non-circular.

[0016] The aforementioned automatic louver replacement device, through the vertical through-type consumables storage unit, allows consumables (louvers) to be stored in a stacked manner along the axial direction, making full use of the internal space of the consumables storage unit. Its push-drive component adopts a rodless cylinder design, which maximizes the travel distance of the consumables in the first direction, thereby allowing the consumables storage unit to hold as many consumables (new louvers) as possible. This fully utilizes the limited space within the consumables storage unit while reducing the frequency of manual replenishment, minimizing equipment downtime, and improving replacement efficiency.

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that if a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. If a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. Where applicable, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation. The operating platform is defined as parallel to the horizontal plane; the first direction can be a vertical direction perpendicular to the horizontal plane, and the second direction can be a horizontal direction.

[0031] In existing technologies, quick-change devices for industrial robot spindle tools typically employ rigid locking structures (such as chucks and pin engagements). While such devices enable basic tool switching, they suffer from the following significant drawbacks in practical applications, especially when frequent changes to different consumable specifications are required:

[0032] First, there is insufficient compatibility with multiple sizes: the rigid interface design makes it difficult to effectively accommodate and stably hold various consumables with large differences in clamping size (such as diameter) (such as grinding wheels of different diameters and louvers of different sizes), which limits the flexibility of the production line.

[0033] Secondly, the positioning accuracy is low and the calibration is cumbersome: after replacing consumables, positioning deviations are easily generated, and the robot trajectory needs to be manually re-taught to correct the tool center point (TCP), resulting in long downtime and affecting production efficiency.

[0034] Secondly, the system lacks adaptive parameter matching: it cannot automatically match the optimal process parameters (such as spindle speed and feed pressure) after changing to different specifications of consumables (such as different particle size louvers), and manual adjustment is required, which can easily cause fluctuations in processing quality.

[0035] Finally, the level of intelligence is low: even when equipped with force sensors, existing technologies have failed to effectively achieve dynamic path compensation to correct clamping or wear errors; at the same time, consumable identification relies on manual input and cannot be linked with the process database to obtain parameters, thus limiting the level of automation.

[0036] As of the above, existing quick-change technology is limited by its rigid design and has shortcomings in terms of compatibility with multi-size consumables, positioning accuracy after replacement, adaptive matching of process parameters, and intelligent compensation recognition, which restrict the efficiency, quality stability, and flexibility of production lines such as grinding / polishing.

[0037] To address the above problems, this application provides an automatic louver replacement device and method, which are described below in conjunction with the appendix. Figure 1-6 The embodiments of this application will be described in further detail.

[0038] See Figure 1 , Figure 1 An overall view of an automatic louver replacement device according to an embodiment of this application is shown. This application provides an automatic louver replacement device for replacing consumables for external tools. In this embodiment, a grinding tool is used as an example for description.

[0039] Specifically, grinding tools require consumables during use, mainly abrasive consumables such as louvers 17, grinding wheels, and milling cutters. This application will specifically describe the replacement of louvers 17 as an example. During the entire grinding process, different consumables need to be replaced when the consumable life is exhausted or when different workpieces need to be ground. This also places demands on the replacement device to be fast and efficient in order to ensure production speed.

[0040] Combination Figure 2 As shown, Figure 2 The diagram shows a hidden portion of the frame of the automatic louver changing device according to an embodiment of this application. In this embodiment, the automatic louver changing device includes at least a frame 1, a pushing assembly 2, a loading / unloading assembly 3, and a control assembly 4 mounted on the frame 1.

[0041] Specifically, the frame 1 includes at least an operating platform 11 and a consumables storage 12. Along the second direction F2, the operating platform 11 has spaced loading / unloading positions and storage positions, with a sliding section 14 defining the loading / unloading positions and the storage positions. In the actual replacement process, the spindle 10 first performs the disassembly process of the louvers 17 at the loading / unloading position, removing the old louvers 17, and then moves to the storage position to insert the new louvers 17, and drives the new louvers 17 to slide along the sliding section 14 until it reaches the loading / unloading position to perform the fastening operation of the louvers 17, thus completing the replacement of the louvers 17.

[0042] The consumables storage 12 is located inside the frame 1 and corresponds to the storage location. The consumables storage 12 is used to store new louver blades 17. The consumables storage 12 extends upward through the operating platform 11 in the first direction F1 to form a storage opening 13 for the new louver blades 17 to be moved out. The storage opening 13 corresponds to the storage location.

[0043] The push assembly 2 is located in the consumables storage 12 and is used to lift the new louver 17 upward, so that the new louver 17 can move upward along the first direction F1 until the topmost new louver 17 is exposed from the storage opening 13 and reaches the storage position for subsequent assembly of the main spindle 10.

[0044] The loading and unloading assembly 3 is set and installed on one side of the frame 1 corresponding to the loading and unloading position. The loading and unloading assembly 3 and the storage opening 13 are arranged at intervals along the second direction F2. The loading and unloading assembly 3 is used to assemble the new louver 17 onto the main shaft 10, or to remove the old louver 17 from the main shaft 10, so as to realize the disassembly and assembly operation of the louver 17.

[0045] The control component 4 includes a control module (not shown) and at least one sensing element 41. The sensing element 41 is mounted on the operating platform 11 and is used to sense whether there are louvers 17 at the location of the storage opening 13. The control module is signal-connected to the sensing element 41 and can control the movement of the push component 2 based on the signal fed back by the sensing element 41. In this embodiment, the sensing element 41 may specifically be a through-beam photoelectric switch. Each sensing element 41 includes a transmitter and a receiver respectively disposed on opposite sides of the storage opening 13. During the disassembly and assembly process, the presence of louvers 17 at the location of the storage opening 13 can be confirmed by whether the receiver receives the signal emitted by the transmitter.

[0046] In this embodiment, when the sensing element 41 detects the presence of a louver 17 at the opening 13, the sensing element 41 sends a signal to the control module, indicating that the installation of a new louver 17 can proceed. Then, the main shaft 10 places the rotor positioning step onto the new louver 17, allowing it to move to the loading / unloading position for subsequent tightening operations. When the sensing element 41 detects the absence of a louver 17 at the opening 13, the sensing element 41 sends another signal to the control module, indicating that a new louver 17 needs to be removed. The control module then controls the pushing assembly 2 to move, pushing the new louver 17 out of the opening 13.

[0047] The aforementioned automatic louver replacement device, through the vertically integrated consumable storage compartment 12, allows the louvers 17 to achieve natural centering under gravity assistance. The spaced arrangement between the loading / unloading assembly 3 and the consumable storage compartment 12 achieves an innovative spatial layout. This layout allows the main spindle 10 to complete assembly and disassembly operations in the horizontal plane, avoiding interference between the vertical movement mechanism and the consumable storage compartment 12. This ensures the positioning stability of the main spindle 10 and provides adaptation space for different specifications of the main spindle 10, enhancing equipment compatibility. Furthermore, in conjunction with the real-time monitoring of the louver 17's status at the storage compartment 13 by the sensing element 41, a closed-loop control logic for the pushing assembly 2 is formed, significantly improving the positioning accuracy and operational reliability of the louver 17 replacement.

[0048] Continue reading Figure 1 As shown, in some embodiments, the frame 1 is generally in the form of a vertical cabinet. The frame 1 also includes a body 15 and a base 16. Different areas within the body 15 form an electrical box 13 and the aforementioned consumables storage 12. Different cavities are also formed within the body 15 according to the needs of the electrical box 13 and the consumables storage 12. The electrical box 13 and the consumables storage 12 are arranged at intervals.

[0049] The electrical box 13 houses the aforementioned control module, enabling the integrated design of the automatic replacement device. A set of forklift holes 161 are provided through the base 16 for the forklift arm to enter, facilitating the movement of the entire automatic replacement device.

[0050] Combination Figure 2 and Figure 3 As shown, Figure 3 It shows Figure 2 Enlarged view of part A. The pushing assembly 2 includes a support 21 and a pushing drive 22 located at the bottom of the consumables storage 12. Specifically, the support 21 can be a tray for supporting new louvers 17. The pushing drive 22 is connected to the support 21 to drive the tray to move upward along the first direction F1. Several new louvers 17 are stacked sequentially on the support 21. Each louver can be moved out of the consumables storage 12 sequentially under the drive of the pushing drive 22 for replacement.

[0051] In this embodiment, the pushing drive 22 can be a cylinder, specifically a magnetically coupled rodless cylinder, including a cylinder body 221, a piston (not shown) disposed within the cylinder body 221, and a slider 222 capable of magnetically coupling with the piston. The cylinder body 221 extends along a first direction F1, and the piston is disposed within the cylinder body 221 and can reciprocate along the first direction F1 under the push of compressed air within the cylinder body 221.

[0052] A through hole (not shown) is provided at the middle of the slider 222 along the first direction F1 for the cylinder 221 to pass through. One side wall of the slider 222 can be connected to the support member 21 by means of a connector (not shown). After the cylinder 221 passes through the through hole, the slider 222 can move synchronously along the first direction F1 under the drive of the piston, and drive the support member 21 and the louvers 17 on the support member 21 to move up and down along the first direction F1. The connector is constructed as a connecting plate arranged along the second direction F2. In the second direction F2, one end of the connector is fixed to the outer wall of the slider 222, and the other end is fixed to the aforementioned support member 21.

[0053] Specifically, the piston is equipped with a permanent magnet ring (not shown), and the slider 222 also contains another set of magnetic rings or magnetic material (not shown). A strong magnetic coupling (attraction) is generated between the slider 222 and the two sets of magnetic rings on the piston. When compressed air drives the internal piston to move, the external slider 222 will synchronously follow the piston and make the same linear motion through the magnetic force.

[0054] The push drive 22 of this application, by means of the rodless cylinder design, can maximize the travel of the support 21 in the first direction F1, thereby enabling the consumables library 12 to accommodate as many new louvers 17 as possible. This makes full use of the limited space inside the device while reducing the frequency of manual replenishment of consumables in the consumables library 12 and reducing downtime for equipment replacement.

[0055] Continue reading Figure 3 As shown, in some embodiments, the pushing assembly 2 further includes a dust cover 26 sleeved around the cylinder body 221. In this application, there are two dust covers 26. Along the first direction F1, the two dust covers 26 are respectively disposed on opposite sides of the slider 222. The side of the dust cover 26 closest to the slider 222 is detachably connected to the end face of the slider 222 to achieve the sealing operation of the through hole on the slider 222, thereby avoiding the operation failure caused by dust entering the through hole during the operation of the pushing drive 22, and improving the smoothness and stability of the operation of the pushing drive 22.

[0056] In some other embodiments, the pushing assembly 2 further includes a positioning element 23 and a positioning drive element 24. The positioning element 23 passes through the aforementioned support member 21 along a first direction F1 and sequentially passes through the mounting holes 171 of each louver 17 within the consumable magazine 12 to fix the radial position of the louvers 17. The positioning drive element 24 is drively connected to the positioning element 23 and can drive the positioning element 23 to reciprocate relative to the support member 21 along the first direction F1.

[0057] In this embodiment, the positioning drive component 24 can specifically be a cylinder, as long as it can achieve a short driving stroke. The positioning component 23 can specifically be a hollow positioning tube, the hollow design of which is used to achieve mutual engagement with the positioning step of the rotor of the main shaft 10.

[0058] Specifically, as the pallet moves the louvers 17 upwards, the positioning component 23 moves simultaneously with the pallet to reduce abnormal radial movement of the louvers 17 during the upward movement. After the uppermost louver 17 is removed from the storage opening 13, the main shaft 10 needs to engage the rotor positioning step with the positioning component 23 and insert the new louver 17. At this time, the positioning component 23 moves downwards and retracts into the consumable storage 12 under the drive of the positioning drive component 24 to avoid interference between the main shaft 10 and the top of the positioning component 23 when the louvers 17 are moved, thus ensuring the smoothness of the replacement operation.

[0059] In some embodiments, the pushing assembly 2 further includes at least one guide platform 27 and at least one guide rod 28. The guide platform 27 is configured as a plate-like platform, and the guide rod 28 is configured as a rod-like structure extending along a first direction F1. When there is only one guide platform 27 and one guide rod 28, the guide platform 27 is horizontally arranged. The upper end surface of the guide platform 27 can be directly or indirectly connected to the bottom surface of the support member 21, and the side surface of the guide platform 27 can be directly or indirectly connected to the slider 222, so as to realize the transmission connection between the support member 21 and the slider 222.

[0060] Specifically, both the guide rod 28 and the positioning element 23 pass through the guide platform 27 along the first direction F1. One end of the guide rod 28 is fixed to the bottom surface of the operating platform 11, and the other end is fixed to the bottom wall of the frame 1. Under the guidance of the guide rod 28, the guide platform 27 always moves up and down along the first direction F1 to achieve the guiding effect of the positioning element 23 of the support 21 in the first direction F1.

[0061] In some other embodiments, there are two guide rods 28 and two guide platforms 27. In this application, for ease of description, the two guide platforms 27 are defined as the first guide platform 271 and the second guide platform 272, respectively. The first guide platform 271 and the second guide platform 272 are arranged at intervals along the first direction F1 and are parallel to each other.

[0062] In this embodiment, the first guide platform 271 is used to directly or indirectly connect to the bottom surface of the support member 21, and the side of the first guide platform 271 can be directly or indirectly connected to the slider 222 to realize the transmission connection between the support member 21 and the slider 222. The second guide platform 272 is used to drive the positioning member 23 to the positioning drive member 24.

[0063] Specifically, along the second direction F2, two guide rods 28 are respectively located at opposite ends of the first guide platform 271 and the second guide platform 272, and pass through the first guide platform 271 and the second guide platform 272 along the first direction F1. One end of the guide rod 28 is fixed to the bottom surface of the operating platform 11, and the other end is fixed to the bottom wall of the frame 1. Under the guidance of the guide rods 28, the first guide platform 271 and the second guide platform 272 always move up and down along the first direction F1. Furthermore, the symmetrical arrangement of the two guide rods 28 can further improve the guiding stability.

[0064] In some embodiments, the bottom end of the positioning member 23 can be directly connected to the piston of the positioning drive member 24 to achieve a transmission connection. In other embodiments, the top surface of the guide table 27 is provided with a mounting base 273, and the positioning member 23 can be mounted on the mounting base 273 along the first direction F1 to achieve a transmission connection with the positioning drive member 24, and to make the positioning drive member 24 unaffected by lateral forces, thus extending its service life.

[0065] See Figure 3 As shown, in some embodiments, the pushing assembly 2 further includes a linear bearing 29 embedded in the guide table 27. The flange portion of the linear bearing 29 is fixed to the guide table 27 by bolts. The aforementioned guide rod 28 can pass through the linear bearing 29 along the first direction F1 to achieve a sliding connection between the guide rod 28 and the guide table 27. In this embodiment, by providing the linear bearing 29, the sliding friction between the guide rod 28 and the guide table 27 can be transformed into rolling friction, thereby reducing the frictional resistance experienced by the guide table 27 during movement and improving the smoothness of the operation of the pushing assembly 2.

[0066] Furthermore, in some embodiments, the pushing assembly 2 further includes a stop member 25 installed on the operating platform 11. The stop member 25 includes a corresponding blocking clamp 251 and a fixing part 252 for installing the blocking clamp 251 onto the operating platform 11. The bottom surface of the blocking clamp 251 is spaced apart from the operating platform 11 and defines a stop interval. The height of the stop interval can only accommodate one louver 17. When the bottom surface of the blocking clamp 251 contacts the top surface of the new louver 17, it indicates that the new louver 17 has been moved into place. Then, the pushing drive member 22 and the positioning drive member 24 are controlled to stop their operation, and the pushing operation of the new louver 17 is stopped.

[0067] Referring to Figure 2 and Figure 4 as shown, Figure 4 it shows Figure 2 an enlarged view of part B in [the figure]. In some embodiments, the automatic replacement device further includes a spacer member 5 installed on the operation platform 11. The spacer member 5 is signal-connected to the control module, and the spacer member 5 can open or close the library opening 13 according to the signal fed back by the sensing element 41.

[0068] In the embodiments of the present application, the spacer member 5 includes a support plate 51 and a pair of barrier members 52. The pair of barrier members 52 can be slidably installed on the support plate 51 along the extension direction of the support plate 51 to realize the opening and closing control of the library opening 13. During the actual operation, when the new hundred-leaf blade 17 is pushed in place, the pair of barrier members 52 simultaneously move closer to the middle of the support plate 51 until they cover above the library opening 13 and are inserted horizontally below the new hundred-leaf blade 17 to prevent the new hundred-leaf blade 17 sleeved on the main shaft 10 from falling downward; when it is necessary to push out the new hundred-leaf blade 17, the pair of barrier members 52 move respectively towards the two ends of the support plate 51 until they move out of the range of the library opening 13, so that the new hundred-leaf blade 17 can be smoothly pushed out.

[0069] Referring to Figure 5 and Figure 6 as shown, Figure 5 it shows a schematic diagram of the automatic replacement device for the main shaft and the hundred-leaf blade in an embodiment of the present application, Figure 6 it shows a schematic diagram of the cooperation between the guide rod and the clamping member of the main shaft in an embodiment of the present application. In some embodiments, the loading and unloading assembly 3 includes a loading and unloading wrench 31 and a wrench driving member 32. The loading and unloading wrench 31 realizes the loading and unloading operation of the fixing nut through forward and reverse installation. The wrench driving member 32 is传动连接于装卸扳手31,并驱使装卸扳手31沿第一方向F1移动。

[0070] In some other embodiments, the loading and unloading assembly 3 further includes a clamping member 6 installed on the frame 1. The clamping member 6 is used to clamp the main shaft 10 to limit the rotation of the main shaft 10. A让位区间7 for the hundred-leaf blade 17 to pass through is formed between the clamping member 6 and the operation platform 11.

[0071] In the embodiments of the present application, the clamping member 6 is configured to have a structure with a "冂"-shaped cross-section. The two sides of the clamping member 6 are fixed to the operation platform 11, and a clamping opening 61 is formed at the top corresponding to the loading and unloading position. The clamping opening 61 can penetrate through the end face of the clamping member 6 facing the library opening 13 along the second direction F2, so that the main shaft 10 can move into the clamping opening 61 along the second direction F2. The inner wall of the clamping opening 61 can be fitted with the edge of the main shaft 10; wherein, the cross-sectional shape of the clamping opening 61 is configured to be non-circular.

[0072] To Figure 6 It should be noted that there is an unclear expression "传动连接于装卸扳手31,并驱使装卸扳手31沿第一方向F1移动" in the original text. It is recommended to check and clarify this part for a more accurate translation.As shown in the example, in this embodiment of the application, the tool holder of the spindle 10 is a hexagonal structure, the bayonet 61 is open on one side and has a chamfered guide. After the guide rod of the spindle 10 is inserted into the bayonet 61, the inner wall of the bayonet 61 engages with the outer wall of the guide rod of the spindle 10 to restrict the rotation of the spindle 10, thereby ensuring the smooth operation of the fixing nut assembly and disassembly.

[0073] Specifically, when it is necessary to remove the fixing nut from the main shaft 10, the wrench drive 32 drives the loading and unloading wrench 31 to move upward along the first direction F1 until the loading and unloading wrench 31 engages with the fixing nut. The loading and unloading wrench 31 then rotates clockwise to remove the nut. Afterward, the wrench drive 32 drives the loading and unloading wrench 31 to move downward, and the fixing nut gets stuck on the loading and unloading wrench 31 and separates from the main shaft 10, causing the old louver 17 to separate from the main shaft 10. The main shaft 10 moves upward, and the old louver 17 remains in place due to the obstruction of the clamping member 6.

[0074] When the fixing nut needs to be installed on the main shaft 10, the main shaft 10 drags the new louver 17 along the slide plate towards the bayonet 61. During this process, the new louver 17 pushes the old louver 17 out of the operating platform 11 through the clearance interval 7. The rotor of the main shaft 10 is restricted from rotating by the bayonet 61. The wrench drive 32 pushes the loading and unloading wrench 31 upward, and the loading and unloading wrench 31 rotates counterclockwise to install the fixing nut on the main shaft 10, thereby achieving the fixed installation of the main shaft 10 and the new louver 17. Then, the wrench drive 32 drives the loading and unloading wrench 31 downward, and the main shaft 10 drives the new louver 17 to the position of the sliding part 14 along the first direction F1, and then moves it upward to complete the replacement operation of the louver 17.

[0075] In this embodiment, the wrench drive component 32 can specifically be a common cylinder.

[0076] Continue reading Figure 1 As shown, in some embodiments, the automatic replacement device further includes a waste trough 8 installed on the frame 1. Along the second direction F2, the storage opening 13, the clamping member 6, and the waste trough 8 are arranged sequentially at intervals. The waste trough 8 is used to collect the old louver blades 17. During the process of the main shaft 10 dragging the sliding part 14 of the new louver blade 17 to move towards the bayonet 61, the new louver blade 17 pushes the old louver blade 17 into the waste trough 8 to realize the automatic collection operation of the old louver blades 17.

[0077] In some other embodiments, the automatic replacement device also includes a guide 9 mounted on the frame 1, the guide 9 being connected between the operating platform 11 and the waste trough 8, and being configured to tilt from the operating platform 11 toward the waste trough 8 so that the old louvers 17 can slide smoothly from the loading / unloading position into the waste trough 8.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
