Description

Technical Field

[0001] This utility model relates to the field of stacking and bundling technology of aluminum alloy ingots, and in particular to an automatic stacking and bundling device for aluminum alloy ingots. Background Technology

[0002] Aluminum alloy ingots are block-shaped ingots made by adding alloying elements such as copper and magnesium to pure aluminum, and then melting and casting them. They are the basic semi-finished products for aluminum alloy material processing. Due to their advantages of strength, corrosion resistance and lightweight, they are mainly used as raw materials. They are then processed into various aluminum alloy products through rolling, extrusion and other processes, and used in the automotive, aerospace and other fields. After the aluminum alloy ingots are produced and processed, they need to be stacked for easy storage and subsequent transportation.

[0003] Currently, the common production method in existing aluminum alloy ingot stacking devices is to set up the stacker and the strapping machine as two independent sets of equipment. After the aluminum ingots are stacked, they are transferred to the strapping station via a conveyor line. In this arrangement, the stacker places the aluminum ingots layer by layer onto the pallet, while the strapping machine performs strapping, tightening, and locking on the transferred aluminum ingot stacks at another location. Although this method achieves basic automation, it suffers from problems such as dispersed equipment and loose process connections. During the transfer of aluminum ingots from the stacking position to the strapping position, due to vibration or unstable conveying, the aluminum ingot stacks are prone to shifting or loosening, affecting the subsequent strapping quality. In severe cases, it may lead to the breakage of the strapping tape or the collapse of the aluminum ingot stack. In addition, the two sets of equipment occupy a large area, the system coordination and control are complex, and the overall efficiency is limited. Therefore, we propose an automatic stacking device for aluminum alloy ingots to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the separation of stacking and bundling equipment, the tendency for aluminum ingot stacks to shift and loosen during transport, which affects bundling quality, and the large footprint and complex control of the two sets of equipment, which limits overall efficiency. Therefore, this invention proposes an automatic stacking and bundling device for aluminum alloy ingots.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic stacking and bundling device for aluminum alloy ingots includes a frame, two movable plates are provided on the top of the frame, two grooves are symmetrically opened on the frame, the two movable plates are located between the two grooves and slide in cooperation with the two grooves, a horizontal drive component and a lifting component are provided on the two movable plates, and a connecting block and a fixing frame are respectively provided below the two lifting components.

[0007] The connecting block is provided with a stacking mechanism, which includes a rotating shaft I and a mounting plate. The rotating shaft I is rotatably disposed at the bottom of the connecting block, and the bottom end of the rotating shaft I is fixedly connected to the top of the mounting plate. The mounting plate is provided with a clamping assembly, and the connecting block is provided with an adjusting assembly for adjusting the direction of the clamping assembly.

[0008] The adjustment assembly includes a worm gear fixedly sleeved on the rotating shaft I and a worm rotatably disposed in the connecting block. The worm gear and the worm are meshed together. A motor I for driving the worm to rotate is fixedly disposed on one side of the connecting block.

[0009] A stacking platform is provided at the bottom of the frame.

[0010] In one possible design, the clamping assembly includes two connecting rods respectively rotatably mounted on both sides of the mounting plate. A rotating block is fixedly sleeved on each of the two connecting rods. The bottom side of the two rotating blocks located on the same connecting rod is fixedly connected to the same clamping plate. The top of the mounting plate is rotatably connected to an electric telescopic rod corresponding to four rotating blocks via a mounting seat. The output ends of the four electric telescopic rods are rotatably connected to the top of the corresponding rotating blocks.

[0011] In one possible design, four limiting rods I slide through the mounting plate, and the bottom ends of two limiting rods I located on the same side are fixedly connected to the same pressure rod. Each of the four limiting rods I is fitted with a spring I, and the top and bottom ends of the four springs I abut against the bottom of the mounting plate and the top of the corresponding pressure rod, respectively.

[0012] In one possible design, the horizontal drive assembly includes four rollers, which are rotatably connected to both sides of the movable plate in pairs via connecting shafts. The four rollers are located in corresponding grooves of the frame and are rotatably connected to the grooves. A rack is fixedly installed on the frame above one of the grooves. A gear is rotatably connected to the top of the movable plate via a drive shaft I. The gear meshes with the rack. A motor III that drives the drive shaft I is fixedly installed at the bottom of the movable plate.

[0013] In one possible design, the lifting assembly includes a rotating shaft II rotatably mounted on the top of a movable plate. The inner wall of the rotating shaft II is threaded and threadedly connected to a lead screw. The bottom end of the lead screw passes through the movable plate and is fixedly connected to the top of a connecting block or a fixed frame. A transmission shaft II is rotatably connected to the top of the movable plate. Both the transmission shaft II and the rotating shaft II are fixedly fitted with pulleys, and the two pulleys are connected to the same belt. A motor II that drives the transmission shaft II to rotate is fixedly mounted on the bottom of the movable plate.

[0014] In one possible design, four slide rods slide through the movable plate, and the bottom ends of the four slide rods are respectively fixedly connected to the top of the connecting block or the fixing frame.

[0015] A bundling device includes the aforementioned automatic stacking device for aluminum alloy ingots, and further includes a bundling mechanism. The bundling mechanism includes a bundling machine fixed on a fixed frame. Guide rails I for guiding the cable ties are fixedly provided on both sides of the bundling machine. Two clearance openings are provided at the bottom of the stacking platform, and guide rails II are provided inside the two clearance openings. When the bundling machine moves above the corresponding guide rail II, the bundling machine is driven to move downward by a lifting component, thereby connecting the two guide rails I and guide rail II to complete the connection of the cable tie tracks for bundling. The top of the fixed frame is fixedly connected to the bottom of the corresponding lead screw.

[0016] In one possible design, a crossbar is fixedly installed on the bottom inner wall of each of the two clearance openings below the corresponding guide rail II. Two limiting rods II are symmetrically fixedly installed on the top of each of the two crossbars. Two limiting blocks are symmetrically fixedly installed on the outer wall of each of the two guide rails II. The four limiting rods II slide through the corresponding limiting blocks. A spring II is fixedly sleeved on each of the four limiting rods II. The top and bottom of the four springs II abut against the bottom of the corresponding limiting block and the top of the corresponding limiting rod II, respectively.

[0017] In this application, firstly, the horizontal drive component of the stacking mechanism is activated: this component drives the transmission shaft I to rotate via motor III, and the transmission shaft I drives the gear to rotate. Since the gear meshes with the rack fixed on the frame, the rotational motion of the motor is converted into horizontal linear motion by utilizing the gear and rack meshing transmission principle. In addition, the rollers at the bottom of the moving plate roll into the groove of the frame, and the rolling friction replaces the sliding friction, reducing the moving resistance and ensuring smooth movement. Finally, the stacking mechanism is driven to move horizontally along the frame until it stops precisely above the aluminum ingot to be grabbed.

[0018] Next, the lifting assembly of the stacking mechanism is activated: motor II drives transmission shaft II to rotate, and the pulley on transmission shaft II drives rotating shaft II to rotate synchronously through the belt; because the inner wall of rotating shaft II has internal threads that mesh with the external threads of the lead screw, the rotational motion of rotating shaft II is converted into the linear lifting motion of the lead screw by using the lead screw and nut transmission principle. At the same time, the slide bar on the moving plate passes through the connecting block to play a guiding and limiting role, preventing the lead screw from driving the connecting block to rotate synchronously with rotating shaft II. Finally, the stacking mechanism is driven to slowly descend and approach the aluminum ingot to be grabbed.

[0019] When the stacking mechanism approaches the aluminum ingot, if it is necessary to adjust the direction of the aluminum ingot, the adjustment component is activated: Motor I in the component drives the worm to rotate, and the worm meshes with the worm wheel sleeved on the rotating shaft I. Utilizing the worm gear transmission principle, it has the characteristics of speed reduction and torque increase, large transmission ratio and self-locking. It can accurately control the rotation angle, and the position is stable and does not deviate after adjustment. The worm wheel drives the rotating shaft I to rotate synchronously, and the bottom of the rotating shaft I is fixed to the mounting plate, thereby driving the clamping component and the aluminum ingot to rotate until it is adjusted to the direction that meets the stacking requirements.

[0020] Then the clamping assembly is activated: the electric telescopic rod in the assembly extends, and its output end pushes the rotating block to rotate around the mounting axis of the connecting rod. Utilizing the lever principle, the linear thrust of the electric telescopic rod is converted into the rotational clamping force of the clamping plate. The two rotating blocks drive the clamping plates on both sides to move closer to the aluminum ingot, thereby clamping the aluminum ingot. At the same time, the limit rod I on the mounting plate slides along the mounting plate, and its bottom pressure rod is in contact with the surface of the aluminum ingot, further preventing the aluminum ingot from shifting during handling.

[0021] After the aluminum ingot is clamped, the lifting component of the stacking mechanism reverses its rotation, lifting the aluminum ingot to a safe height. The horizontal drive component of the stacking mechanism starts again, transferring the aluminum ingot to the designated area above the stacking platform. Then the lifting component drives the aluminum ingot to descend slowly. When the aluminum ingot contacts the stacked layer or platform below, the electric telescopic rod retracts, causing the clamping plate to open, completing the stacking of the aluminum ingot. Due to the precise transmission of the gear rack, screw nut and the direction adjustment of the worm gear in the early stage, the aluminum ingot is stacked in an accurate position and the layers are tightly fitted.

[0022] When the aluminum ingots are stacked to the preset height, the horizontal drive component of the strapping mechanism is activated to move the strapping mechanism directly above the stack of aluminum ingots. The lifting component of the strapping mechanism is then activated to drive the strapping mechanism to descend, bringing the guide rails I on both sides of the strapping machine closer to the guide rails II in the clearance opening of the stacking platform. When the guide rails are aligned, guide rail I presses down on guide rail II, and guide rail II slides along limit rod II through the limit block. Spring II is compressed, and by utilizing the elastic deformation principle of the spring, flexible alignment is achieved, compensating for minor positional errors between the guide rails and avoiding damage to components from hard collisions. At the same time, limit rod II restricts the lateral displacement of guide rail II, ensuring that guide rail I and guide rail II are precisely aligned, forming a closed strapping conveying path. The strapping machine continues to descend, and its bottom applies pressure to the aluminum ingot stack, using the pressure to compact the stack and prevent it from loosening during strapping.

[0023] Finally, the strapping machine starts, and the cable ties are sent out from its outlet, circling the aluminum ingot stack once along the closed path formed by guide rail I and guide rail II. Then the strapping machine completes the tightening, hot-melt welding and cutting of the cable ties. After the strapping is completed, the lifting component of the strapping mechanism drives the strapping machine to rise, guide rail I and guide rail II separate, guide rail II resets under the elastic force of spring II, and the horizontal drive component of the strapping mechanism drives it back to the initial position, completing a complete stacking and strapping process.

[0024] Beneficial Effects: This utility model discloses an automatic stacking and bundling device for aluminum alloy ingots. By integrating the stacking and bundling mechanisms onto the same frame and equipping them with horizontal movement and lifting functions, it enables the continuous completion of stacking and bundling processes at the same workstation. This arrangement avoids the need for inter-process transfer of aluminum ingot stacks, fundamentally eliminating the problem of stack misalignment or loosening caused by conveyor vibration, thereby improving the stability of the bundling process and the quality of the finished product. Simultaneously, the integrated structure reduces the equipment's footprint, simplifies the system control logic, and helps improve overall operational efficiency while reducing equipment investment costs.

[0025] In this invention, an automatic stacking and bundling device for aluminum alloy ingots utilizes an adjustment assembly consisting of a rotating shaft, worm gear, and worm in the stacking mechanism. This assembly allows for flexible adjustment of the ingot's orientation before placement, adapting to different stacking patterns. The clamping assembly, driven by an electric telescopic rod, rotates the block and clamping plate to stably grip and release the ingot. Combined with a limit rod and spring structure, it provides cushioning and maintains positional stability during ingot placement. This design ensures more accurate placement and tighter interlayer adhesion of the ingots during stacking, improving the overall stability of the ingot stack and creating favorable conditions for subsequent bundling.

[0026] In this utility model, the automatic stacking and bundling device for aluminum alloy ingots, through the cooperation of a liftable bundling machine and a guide rail II on the stacking platform, can accurately connect the guide rail with the outlet of the bundling machine before bundling, forming a closed bundling path. During the downward pressing process, the bundling machine can apply a certain pressure to the aluminum ingot stack, further compacting the stack and preventing loosening during the bundling process. The guide rail and the bundling machine are flexibly connected through springs and limit rods, which can compensate for positional errors, ensure that the strapping tape passes through smoothly and is not prone to deviation, thereby improving the success rate and firmness of bundling.

[0027] In this invention, by integrating the stacking and bundling mechanisms onto the same frame, the two processes are completed continuously at the same station, eliminating the problem of aluminum ingot stack misalignment caused by transportation. The stacking mechanism uses a worm gear to adjust the direction of the aluminum ingots, and works with a buffered clamping assembly to ensure accurate and stable stacking. During bundling, a closed path is formed through guide rail docking, and the ingot stack is compacted during the pressing process. Combined with a flexible docking mechanism to compensate for errors, the bundling strength and success rate are effectively improved. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] In one embodiment: Refer to Figure 1-5 An automatic stacking device includes a frame 1, which serves as an integral support base. Two grooves are symmetrically formed on the top of the frame 1, and two movable plates 15 are disposed between these grooves, forming a sliding fit with the frame 1. Each movable plate 15 is equipped with a horizontal drive assembly and a lifting assembly. A connecting block 10 is fixedly connected below the lifting assembly of one movable plate 15, and a stacking mechanism for gripping and placing aluminum alloy ingots is mounted below the connecting block 10. A fixing frame 23 is fixedly connected below the lifting assembly of the other movable plate 15, and a binding mechanism for bundling the stacked aluminum ingots is mounted on the fixing frame 23.

[0036] A stacking platform 26 is fixedly installed at the bottom of the frame 1. The stacking platform 26 provides a load-bearing foundation for stacking aluminum ingots. The overall structure integrates the stacking mechanism and the bundling mechanism on the same frame 1, providing structural support for the continuous operation of the two processes.

[0037] The horizontal drive assembly is used to drive the stacking mechanism or strapping mechanism to move horizontally along the frame 1. Its specific structure includes four rollers, which are connected in pairs to the two sides of the moving plate 15 via connecting shafts. Each roller is embedded in one of the two grooves of the frame 1 and rolls against the inner wall of the groove. A rack 22 is fixedly mounted above one of the grooves on the frame 1. A drive shaft I is rotatably connected to the top of the moving plate 15 via a bearing. A gear 21 is fixedly mounted on the drive shaft I, meshing with the rack 22. The bottom of the moving plate 15 is fixed with bolts. Motor Ⅲ20 is installed, and the output shaft of motor Ⅲ20 is fixedly connected to one end of transmission shaft Ⅰ via a coupling. When motor Ⅲ20 is started, motor Ⅲ20 drives transmission shaft Ⅰ to rotate, and transmission shaft Ⅰ drives gear 21 to rotate synchronously. With the meshing transmission of gear 21 and rack 22, the rotational motion of motor Ⅲ20 is converted into the horizontal linear motion of moving plate 15. At the same time, the rolling cooperation between roller and groove converts sliding friction into rolling friction, effectively reducing movement resistance and ensuring that the moving plate 15 drives the stacking mechanism or strapping mechanism to move smoothly, thereby ensuring the accuracy of subsequent gripping or strapping.

[0038] The lifting assembly is used to drive the stacking mechanism or strapping mechanism to achieve lifting movement. Its specific structure includes a rotating shaft II 16 rotatably mounted on the top of the moving plate 15. The rotating shaft II 16 is rotatably engaged with the moving plate 15 via bearings. The inner wall of the rotating shaft II 16 is machined with internal threads, and a lead screw 17 is connected to these threads. The bottom end of the lead screw 17 passes through the moving plate 15 and is fixedly connected to the top of the connecting block 10 or the fixing frame 23 by bolts. A transmission shaft II is also rotatably connected to the top of the moving plate 15 via bearings. Both the transmission shaft II and the rotating shaft II 16 are fixedly fitted with pulleys, and the two pulleys are connected by the same belt. A motor II 18 is fixedly mounted on the bottom of the moving plate 15 by bolts. The output shaft of the motor II 18 is connected to the transmission shaft II via a coupling. One end is fixedly connected; four slide rods 19 also slide through the moving plate 15, and the bottom ends of the four slide rods 19 are respectively fixedly connected to the top of the connecting block 10 or the fixed frame 23 by bolts; when the motor II 18 is started, the motor II 18 drives the transmission shaft II to rotate, and the pulley on the transmission shaft II drives the rotating shaft II 16 to rotate synchronously through the belt. With the help of the threaded engagement between the rotating shaft II 16 and the lead screw 17, the rotational motion of the rotating shaft II 16 is converted into the linear lifting motion of the lead screw 17. The four slide rods 19 can guide and limit the connecting block 10 or the fixed frame 23, preventing the lead screw 17 from driving the connecting block 10 or the fixed frame 23 to rotate synchronously with the rotating shaft II 16, ensuring the stability of the stacking mechanism or the binding mechanism during the lifting process, and avoiding the aluminum ingot from shifting during the grabbing or handling process.

[0039] The stacking mechanism includes a rotating shaft I11 and a mounting plate 2. The rotating shaft I11 is rotatably mounted at the bottom of the connecting block 10 via bearings. The bottom end of the rotating shaft I11 is fixedly connected to the top of the mounting plate 2 via bolts. The mounting plate 2 is equipped with a clamping assembly for gripping aluminum ingots. The connecting block 10 is equipped with an adjusting assembly for adjusting the placement direction of the aluminum ingots. The adjusting assembly includes a worm gear 12 and a worm 13. The worm gear 12 is fixedly sleeved on the rotating shaft I11 and located inside the connecting block 10. The worm 13 is rotatably mounted inside the connecting block 10 via bearings. The worm gear 12 and the worm 13 are meshed together. A motor I14 is fixedly mounted on one side of the connecting block 10 via bolts. The output shaft of the motor I14 is fixedly connected to one end of the worm 13 via a coupling. When the placement direction of aluminum ingots needs to be adjusted to adapt to different stacking modes, motor I14 is started. Motor I14 drives worm gear 13 to rotate, worm gear 13 drives meshing worm wheel 12 to rotate synchronously, worm wheel 12 drives rotating shaft I11 to rotate, which in turn drives mounting plate 2 and clamping assembly to rotate synchronously, thereby realizing the adjustment of aluminum ingot direction. The transmission structure of worm wheel 12 and worm gear 13 has the characteristics of speed reduction and torque increase and self-locking, which can accurately control the rotation angle, and the position of aluminum ingots is stable and does not shift after adjustment, thus ensuring accurate stacking of aluminum ingots.

[0040] The clamping assembly includes two connecting rods 3, which are rotatably mounted on both sides of the mounting plate 2 via bearings. Rotating blocks 4 are fixedly fitted onto each of the two connecting rods 3. The bottom sides of the two rotating blocks 4 on the same connecting rod 3 are bolted to the same clamping plate 5. Four electric telescopic rods 6 are rotatably connected to the top of the mounting plate 2 via mounting seats. Each of the four electric telescopic rods 6 corresponds to one of the four rotating blocks 4. The output end of each electric telescopic rod 6 is rotatably connected to the top of the corresponding rotating block 4 via a pin. Four limiting rods I7 also slide through the mounting plate 2. The bottom ends of two limiting rods I7 on the same side are bolted to the same pressure rod 8. Springs I9 are fitted onto each of the four limiting rods I7. The top and bottom ends of the springs I9 abut against the bottom of the mounting plate 2 and the top of the corresponding pressure rod 8, respectively. When it is necessary to grip the aluminum ingot, the electric telescopic rod 6 is activated. The output end of the electric telescopic rod 6 extends and pushes the rotating block 4 to rotate around the axis of the connecting rod 3. Using the lever principle, the rotating block 4 drives the clamping plate 5 to move towards the aluminum ingot, thereby clamping the aluminum ingot. At the same time as the clamping plate 5 clamps the aluminum ingot, the pressure rod 8 is pressed against the surface of the aluminum ingot under the elastic force of the spring I9. The elastic deformation of the spring I9 can provide a buffering effect, avoiding damage to the aluminum ingot due to excessive clamping force, and further preventing the aluminum ingot from shifting during transportation, ensuring stable gripping of the aluminum ingot.

[0041] This application can be used in the field of stacking and bundling of aluminum alloy ingots, and can also be used in other fields applicable to this application.

[0042] In another embodiment: Reference Figure 2-5Based on the first embodiment, an improvement is made to an automatic stacking and bundling device for aluminum alloy ingots, which is applied to the field of stacking and bundling technology of aluminum alloy ingots. The bundling mechanism includes a bundling machine 24 fixed on a fixed frame 23. The bundling machine 24 is fixedly connected to the fixed frame 23 by bolts. Guide rails I 25 are fixedly provided on both sides of the bundling machine 24 by bolts. The guide rails I 25 are used to guide the bundling straps. The stacking platform 26 has two clearance openings at its bottom. Each clearance opening has a guide rail II 27 inside. A crossbar is bolted to the inner bottom wall of each clearance opening below the corresponding guide rail II 27. Two limit rods II 28 are symmetrically bolted to the top of each crossbar. Two limit blocks are symmetrically bolted to the outer wall of each guide rail II 27. The four limit rods II 28 slide through their respective limit blocks. A spring II 29 is fixedly fitted onto each of the four limit rods II 28, with its top and bottom abutting against the bottom of the corresponding limit block and the top of the corresponding limit rod II 28, respectively. When the aluminum ingots are stacked to a preset height and need to be bundled, the horizontal drive assembly moves the bundling machine 24 directly above the stack of aluminum ingots. The lifting assembly then lowers the bundling machine 24, aligning guide rail I 25 with guide rail II 27. During the docking process, guide rail I25 presses down on guide rail II27, and guide rail II27 slides along limit rod II28 through the limit block. Spring II29 is compressed, and flexible docking is achieved by means of the elastic deformation of spring II29. This can compensate for the small positional error between guide rail I25 and guide rail II27 and avoid damage to components from hard collisions. Limit rod II28 can limit the lateral displacement of guide rail II27, ensuring that guide rail I25 and guide rail II27 are precisely aligned and form a closed cable tie conveying path.

[0043] When stacking and bundling aluminum alloy ingots are required, motor III 20 in the horizontal drive assembly corresponding to the stacking mechanism is activated. Motor III 20 drives transmission shaft I to rotate, which in turn drives gear 21 to rotate. Gear 21 meshes with rack 22, causing moving plate 15 to move, bringing the stacking mechanism directly above the aluminum ingot to be grasped. Motor II 18 in the lifting assembly corresponding to the stacking mechanism is then activated. Motor II 18 drives transmission shaft II to rotate, which in turn drives rotating shaft II 16 to rotate via pulleys and belts. Rotating shaft II 16, in conjunction with lead screw 17, lowers the stacking mechanism until the clamping assembly is close to the aluminum ingot. If direction adjustment is required, motor I 14 drives worm gear 13 to rotate, which in turn drives rotating shaft I 11 to rotate via worm wheel 12, adjusting the orientation of mounting plate 2 and clamping assembly. The electric telescopic rod 6 is activated to clamp the aluminum ingot with the clamping plate 5. The pressure rod 8, under the action of spring I 9, adheres to the aluminum ingot. Then, the lifting assembly raises the aluminum ingot, and the horizontal drive assembly moves it above the stacking platform 26. The lifting assembly then lowers and releases the clamping plate 5, completing the aluminum ingot stacking. The above steps are repeated until the aluminum ingots are stacked to the preset height. Then, the horizontal drive assembly and lifting assembly of the strapping mechanism are activated, causing the strapping machine 24 to move above the aluminum ingot stack and lower. Guide rail I 25 and guide rail II 27 flexibly connect to form a closed path. After the strapping machine 24 presses down to compact the aluminum ingot stack, the strapping tape is conveyed along the guide rail and tightened, heat-melted, and cut. After strapping is completed, the lifting assembly raises the strapping machine 24, guide rail I 25 separates from guide rail II 27, and guide rail II 27 resets under the action of spring II 29. The strapping mechanism moves back to its initial position, completing one complete operation. The entire process allows stacking and strapping to be completed continuously at the same workstation, avoiding stack offset caused by transportation and improving work efficiency and quality.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of motor I 14, motor II 18, motor III and strapping machine 24 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
