Description

Technical Field

[0001] This invention relates to the field of aluminum sheet stretching technology, and more specifically to a feeding device for aluminum sheet stamping and stretching. Background Technology

[0002] With the increasing application of aluminum sheets, they are being processed into various shapes. Existing aluminum sheet processing equipment requires manual feeding, resulting in slow processing efficiency and a higher risk of accidents. Chinese Patent CN113441641B discloses an automated aluminum sheet stamping and stretching feeding device, including an intermittent feeding unit and a stretching unit. The intermittent feeding unit continuously feeds the aluminum sheet to the stretching unit, which then stamps and stretches the sheet. This patent's intermittent feeding unit continuously pushes the aluminum sheet onto the die, eliminating the need for manual feeding and preventing accidents caused by negligence. The incident occurred, but the feeding mechanism moved the bottom aluminum plate of the material box towards the stamping mechanism. Since the weight of the remaining aluminum plates in the material box is concentrated on the bottom aluminum plate, when the feeding mechanism pushes the bottom aluminum plate in the material box, the weight of the remaining aluminum plate is too heavy, causing the bottom aluminum plate to rub against its adjacent aluminum plates during the feeding process. This results in scratches on the surface of the aluminum plate during stamping, affecting the use of the product. The heavier the aluminum plates stacked in the material box, the more severe the scratches will be when the feeding mechanism moves the aluminum plates. At the same time, it may also cause the feeding mechanism to be unable to move the bottom aluminum plate in the material box due to the weight. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a feeding device for aluminum sheet stamping and stretching. Through the inclusion of a top-feeding mechanism, the feeding mechanism supports the remaining aluminum sheets in the material box while the aluminum sheet is being moved. This creates a gap between the bottom aluminum sheet and its adjacent sheets as the sheet passes through the box, reducing the likelihood of scratches caused by friction between the bottom sheet and the sheets above it, thus improving product quality. Furthermore, the fact that both the feeding mechanism and the two top-feeding mechanisms are connected to the stamping mechanism eliminates the need for additional drive sources and intermittent mechanisms, improving the synchronization of multiple mechanisms and increasing stamping efficiency.

[0004] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0005] A feeding device for stamping and stretching aluminum plates includes a frame, a material box mounted on the frame, and a stamping mechanism. The bottom of the material box is provided with a feeding mechanism for pushing the material at the bottom of the material box toward the stamping mechanism. The bottom of the material box near the stamping mechanism is provided with a discharge port for only a single material to pass through.

[0006] The material box has slots on two sides adjacent to the discharge port, and a lifting mechanism is provided on the side of the two slots to lift the remaining material in the material box when the feeding mechanism moves the material at the bottom of the material box.

[0007] The feeding mechanism and the two ejector mechanisms are all connected to the stamping mechanism via a transmission.

[0008] Preferably, both top feeding mechanisms include a top feeding plate, a limiting component, two turntables, and two connecting rods. The limiting component is slidably located on the side of the slot, and the sliding direction of the limiting component is perpendicular to the direction in which the feeding mechanism drives the material. The top feeding plate is vertically slidable on the limiting component. Rotating shafts are provided on both sides of the slot on the material box, and the axes of the two rotating shafts are coaxial. The two turntables are respectively sleeved on the ends of the two rotating shafts that are close to each other. Fixed shafts parallel to the axes of the rotating shafts are provided on the edges of the two turntables. One end of each of the two connecting rods is sleeved on the fixed shaft of the two turntables, and the other end of each connecting rod is hinged to both ends of the top feeding plate.

[0009] Preferably, the limiting component includes a sliding seat, two first guide shafts, and two first elastic members. A first slide rail perpendicular to the material movement direction is provided on the side of the slot. The sliding seat is slidably located on the first slide rail. The two first guide shafts are both vertically located on the sliding seat. The two first elastic members are sleeved on the two first guide shafts. A fixing block is provided on the top of each of the two first guide shafts. A support plate is provided on the side of the top plate near the sliding seat. The support plate is horizontally arranged and sleeved on the two first guide shafts. The two ends of the first elastic members are fixedly connected to the support plate and the fixing block, respectively.

[0010] Preferably, the feeding mechanism includes a slider, a lead screw, and two mounting seats. The two mounting seats are fixedly connected to the frame and located below the material box. The lead screw is rotatable and located between the two mounting seats. The slider is sleeved on the lead screw and threadedly engaged with it. A second slide rail parallel to the axis of the lead screw is provided at the top of the frame. The slider is slidably engaged with the second slide rail. A drive block elastically connected to the slider is provided. The drive block can slide along the vertical direction of the material box and is elastically connected to the slider. The top of the drive block is sloping, and the side of the drive block closer to the stamping mechanism is higher than the side farther from the stamping mechanism. A clearance opening matching the drive block is provided on the opposite side of the material box at the discharge port.

[0011] Preferably, the top of the drive block is provided with two rollers, the axes of which are perpendicular to the axis of the lead screw.

[0012] Preferably, a mounting box is provided on the side of the slider and near the stamping mechanism. Two second guide shafts, both parallel to the axis of the lead screw, are provided on both sides of the mounting box. The two second guide shafts pass through the slider and slide with it. A second elastic element is sleeved on each of the two second guide shafts. The drive block is slidably located inside the mounting box.

[0013] Preferably, the inner wall of the discharge port is provided with an inclined groove.

[0014] Preferably, two drive shafts with axes parallel to the axis of rotation are arranged on the frame below the stamping mechanism. A first gear is sleeved on each of the two drive shafts. The stamping mechanism is provided with a stamping plate that can slide in the vertical direction. The two sides of the stamping plate are provided with racks that are the same number as the number of drive shafts and correspond one-to-one. The racks are meshed with the first gears. The lead screw of the feeding mechanism is driven by one of the drive shafts. The two rotating shafts of the ejector mechanism are driven by the drive shafts on the same side.

[0015] Preferably, a first transmission shaft parallel to the axis of each of the two rotating shafts of the top material mechanism is provided on the side of each of the two rotating shafts. A second gear is sleeved on both the rotating shaft and the first transmission shaft. The two second gears are meshed and connected. Both first transmission shafts are connected to the drive shaft below the frame.

[0016] Preferably, a second drive shaft is provided on the side of the lead screw, and two synchronous belts are sleeved on the second drive shaft. The two synchronous belts are respectively connected to the lead screw and the drive shaft.

[0017] When the lead screw is connected to the drive shaft, and the slide moves to the mounting seat near the stamping mechanism, the mounting box connected to the slider will pass through the mounting seat. At this time, the timing belt will interfere with the movement of the mounting box, thereby affecting the feeding of the aluminum plate by the drive block inside the mounting box. By setting the second transmission shaft, the timing belt can avoid the movement path of the mounting box, thus improving the stability of the equipment operation.

[0018] The advantages of this invention compared to the prior art are:

[0019] This invention, through the design of a top-feeding mechanism, allows the top-feeding mechanism to support the remaining aluminum plates in the material box while the feeding mechanism moves the aluminum plates. This creates a gap between the bottom aluminum plate and its adjacent plates as the plate passes through the material box, reducing the possibility of scratches caused by friction between the bottom plate and the plate above it, thus improving product quality. Simultaneously, it requires less output power from the feeding mechanism, preventing the feeding mechanism from being unable to push the bottom aluminum plate in the material box, improving the stability of the device's operation, and enabling the device to accommodate products of different weights, thus improving product adaptability. Since both the feeding mechanism and the two top-feeding mechanisms are connected to the stamping mechanism, the equipment does not require an additional drive source. Each stamping operation sends an aluminum plate to the bottom of the stamping mechanism via the feeding mechanism, eliminating the need for intermittent mechanisms. This improves the synchronization of operation between multiple mechanisms and increases stamping efficiency. Attached Figure Description

[0049] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0050] like Figures 1 to 4 , Figure 12 and Figure 13 As shown: A feeding device for stamping and stretching aluminum plates includes a frame 1, a material box 14 disposed on the frame 1, and a stamping mechanism 11. The bottom of the material box 14 is provided with a feeding mechanism 3 for pushing the material at the bottom of the material box 14 to move towards the stamping mechanism 11. The bottom of the material box 14 is provided with a discharge port 141 for a single material to pass through on the side near the stamping mechanism 11.

[0051] On the material box 14, slots 142 are provided on the two sides adjacent to the discharge port 141. On the side of the two slots 142, a lifting mechanism 2 is provided for lifting the remaining material in the material box 14 when the feeding mechanism 3 moves the material at the bottom of the material box 14.

[0052] The feeding mechanism 3 and the two ejector mechanisms 2 are all connected to the stamping mechanism 11 via transmission.

[0053] In the prior art, the feeding mechanism 3 moves the bottom aluminum plate 144 of the material box 14 towards the stamping mechanism 11. Since the weight of the remaining aluminum plates 144 in the material box 14 is concentrated on the bottom aluminum plate 144, when the feeding mechanism 3 moves the bottom aluminum plate 144 in the material box 14, the excessive weight of the remaining aluminum plate 144 causes friction between the bottom aluminum plate 144 and its adjacent aluminum plates 144 during the feeding process. This results in scratches on the surface of the aluminum plate 144 during stamping, affecting the use of the product. The heavier the stacked aluminum plates 144 in the material box 14, the more severe the scratches caused when the feeding mechanism 3 moves the aluminum plates 144. Furthermore, the feeding mechanism 3 may be unable to move the bottom aluminum plate 144 in the material box 14 due to its weight. By setting up the top feeding mechanism 2, when the feeding mechanism 3 moves the aluminum plate 144, the top feeding mechanism 2 can support the remaining aluminum plates 144 in the material box 14, allowing the aluminum plates 144 to move along the material box. The vertical upward movement of the feeding mechanism 14 creates a gap between the bottom aluminum plate 144 and the aluminum plate 144 above it as the plate passes through the material box 14. This facilitates the passage of the aluminum plate 144 while reducing the possibility of scratches caused by friction between the aluminum plate 144 and its adjacent plates, thus improving product quality. Simultaneously, it requires less output power from the feeding mechanism 3, preventing the feeding mechanism 3 from being unable to push the bottom aluminum plate 144 within the material box 14, improving the stability of the device's operation, and enabling the device to accommodate products of different weights, thus enhancing product adaptability. Because the feeding mechanism 3 and the two top-feeding mechanisms 2 are all connected to the stamping mechanism 11, the equipment does not require additional drive sources. Each stamping operation sends an aluminum plate 144 to the bottom of the stamping mechanism 11 via the feeding mechanism 3, eliminating the need for intermittent mechanisms. This improves the synchronization between multiple mechanisms and increases stamping efficiency.

[0054] like Figures 1 to 6 and Figure 10 As shown: Both top feeding mechanisms 2 include a top feeding plate 21, a limiting component 22, two turntables 25, and two connecting rods 24. The limiting component 22 is slidably located on the side of the slot 142, and the sliding direction of the limiting component 22 is perpendicular to the direction in which the feeding mechanism 3 drives the material. The top feeding plate 21 is vertically slidable on the limiting component 22. Rotating shafts 23 are provided on both sides of the slot 142 on the material box 14. The axes of the two rotating shafts 23 are coaxially arranged. The two turntables 25 are respectively sleeved on the two rotating shafts 23 at their close ends. Fixed shafts 251 parallel to the axes of the rotating shafts 23 are provided on the edges of the two turntables 25. One end of each of the two connecting rods 24 is sleeved on the fixed shafts 251 of the two turntables 25, and the other end of each connecting rod 24 is hinged to both ends of the top feeding plate 21.

[0055] By synchronously rotating two rotating shafts 23, the two rotating shafts 23 drive the turntable 25 connected to them. The rotation of the turntable 25 drives the fixed shaft 251 on its edge, which in turn drives the connecting rod 24 connected to it. This causes the end of the connecting rod 24 to rotate around the axis of the rotating shaft 23. Since the other end of the connecting rod 24 is hinged to the end of the top plate 21, the movement of the connecting rod 24 drives the movement of the top plate 21. This causes the top plate 21 to move around the axis of the rotating shaft 23. When the top plate 21 approaches the side of the material box 14, it passes through the slot 142 and abuts against the edge of the remaining aluminum plate 144 in the material box 14. This causes the remaining aluminum plate 144 to be lifted upward along the material box 14, reducing the weight pressing on the bottom aluminum plate 144 of the material box 14. At the same time, this creates a small gap between the aluminum plate 144 moved by the feeding mechanism 3 and the aluminum plate 144 above it. This facilitates the feeding mechanism 3 to move the aluminum plate 144 through the discharge port 141 to below the stamping mechanism 11. During the return stroke of the feeding mechanism 3, the top plate 21 will move away from the material box 14 under the action of the connecting rod 24, so that all the aluminum plates 144 in the material box 14 fall into the material box 14. This makes it convenient for the feeding mechanism 3 to continue feeding the aluminum plate 144 at the bottom of the material box 14. This process is repeated until all the aluminum plates 144 in the material box 14 are transported to below the stamping mechanism 11. The top plate 21 can slide on the limiting component 22, which can slide beside the slot 142. The sliding direction of the limiting component 22 is perpendicular to the moving direction of the aluminum plate 144, so that the top plate 21 can maintain its stability on the aluminum plate 144 in the material box 14 when it is driven by the connecting rod 24. This allows the top plate 21 to accurately lift the remaining aluminum plates 144 in the material box 14.

[0056] like Figures 1 to 6 and Figure 10 As shown: The limiting component 22 includes a sliding seat 221, two first guide shafts 222 and two first elastic elements 2222. A first slide rail 223 perpendicular to the material movement direction is provided on the side of the slot 142. The sliding seat 221 is slidably located on the first slide rail 223. The two first guide shafts 222 are both vertically located on the sliding seat 221. The two first elastic elements 2222 are sleeved on the two first guide shafts 222. A fixing block 2221 is provided on the top of each of the two first guide shafts 222. A support plate 211 is provided on the side of the top plate 21 near the sliding seat 221. The support plate 211 is horizontally arranged and sleeved on the two first guide shafts 222. The two ends of the first elastic elements 2222 are fixedly connected to the support plate 211 and the fixing block 2221, respectively.

[0057] When the connecting rod 24 drives the top plate 21 to move, the top plate 21 will drive the support plate 211 connected to it. The support plate 211 will drive the two first guide shafts 222 to move, and the two first guide shafts 222 will drive the sliding seat 221 to slide. This causes the top plate 21 to drive the sliding seat 221 to reciprocate linearly along the first slide rail 223 when it rotates around the rotation axis 23. At the same time, the support plate 211 will reciprocate linearly along the axis of the two first guide shafts 222. Since the top plate 21 and the two connecting rods 24 move together, the top plate 21 will move along the axis of the two first guide shafts 222. The connecting rod 24 is hinged, and it will slide when the top plate 21 abuts against the aluminum plate 144 in the material box 14. As a result, it cannot provide a stable lifting force to the aluminum plate 144, making the lifting effect unsatisfactory. By setting the limiting component 22, the position of the top plate 21 is limited when lifting the aluminum plate 144, so that the lifting effect of the top plate 21 on the aluminum plate 144 is better. The first elastic element 2222 is used to buffer the impact force of the movement between the components and extend the service life of the components.

[0058] like Figures 1 to 4 , Figures 7 to 9 and Figure 11 As shown: The feeding mechanism 3 includes a slider 31, a lead screw 321, and two mounting seats 32. The two mounting seats 32 are fixedly connected to the frame 1 and located below the material box 14. The lead screw 321 is rotatably located between the two mounting seats 32. The slider 31 is sleeved on the lead screw 321 and threadedly engaged with it. The top of the frame 1 is provided with a second slide rail 322 parallel to the axis of the lead screw 321. The slider 31 is slidably engaged with the second slide rail 322. The slider 31 is provided with a driving block 331 elastically connected to it. The driving block 331 can slide along the vertical direction of the material box 14, and the driving block 331 is elastically connected to the slider 31. The top of the driving block 331 is sloping, and the side of the driving block 331 closer to the stamping mechanism 11 is higher than the side farther away from the stamping mechanism 11. The material box 14 is provided with a clearance opening 143 matching the driving block 331 on the opposite side of the discharge port 141.

[0059] By rotating the lead screw 321, the slider 31, which is threadedly engaged with the lead screw 321, can slide along the second slide rail 322. The sliding of the slider 31 drives the drive block 331 connected to it. The initial position of the slider 31 is located beside the material box 14 and away from the stamping mechanism 11. The slider 31 drives the drive block 331 to enter the material box 14 through the clearance opening 143. The drive block 331 drives the aluminum plate 144 at the bottom of the material box 14 to move, so that the aluminum plate 144 exits from the discharge port 1 on the other side of the material box 14. 41 is moved out until it moves to the bottom of the stamping mechanism 11. When the slider 31 returns, because the top of the drive block 331 is sloping, when the drive block 331 contacts the aluminum plate 144 in the material box 14, the drive block 331 moves downward along the vertical direction of the material box 14, so that the top of the drive block 331 returns to the initial position with the bottom aluminum plate 144 in the material box 14. After returning to the origin, the drive block 331 will reset under the action of elasticity, so that it can continue to pop out and move the aluminum plate 144 next time.

[0060] like Figure 8 and Figure 11 As shown: The top of the drive block 331 is provided with two rollers 332, and the axis of the rollers 332 is perpendicular to the axis of the lead screw 321.

[0061] When the slider 31 drives the drive block 331 back, the drive block 331 retracts to the bottom of the material box 14, but its top still contacts the bottom aluminum plate 144 inside the material box 14. This may cause scratches on the aluminum plate 144 during the return stroke, damaging the aluminum plate 144. The roller 332 is designed so that when the drive block 331 returns, its roller 332 contacts the bottom surface of the aluminum plate 144, reducing the friction between the drive block 331 and the aluminum plate 144. This reduces scratches on the aluminum plate 144, improves product quality, and also... When the aluminum plate 144 is moved towards the stamping mechanism 11 by the 331, although a certain gap will be generated between the bottom aluminum plate 144 and the remaining aluminum plates 144 under the lifting of the top material mechanism 2, if the top material mechanism 2 fails to accurately lift all the remaining aluminum plates 144, there may be a small portion of the remaining aluminum plates 144 still pressing on the aluminum plates 144 driven by the feeding mechanism 3. By setting the roller 332, the friction between it and the aluminum plate 144 above it can be reduced, avoiding the generation of scratches and further improving the quality of the product.

[0062] like Figures 1 to 4 , Figures 7 to 9 and Figure 11As shown: A mounting box 33 is provided on the side of the slider 31 and near the stamping mechanism 11. Two second guide shafts 333 are provided on both sides of the mounting box 33, both of which are parallel to the axis of the lead screw 321. The two second guide shafts 333 pass through the slider 31 and slide with it. A second elastic element 334 is sleeved on each of the two second guide shafts 333. The drive block 331 is slidably located inside the mounting box 33.

[0063] To improve the positioning accuracy of the aluminum plate 144, a positioning mechanism is typically installed on the stamping mechanism 11. When the drive block 331 moves the aluminum plate 144, a limiting plate is installed on the positioning mechanism to prevent excessive movement of the aluminum plate 144. After the slider 31 moves the aluminum plate 144 into contact with the limiting plate, the positioning mechanism fixes the aluminum plate 144, thereby improving the stamping accuracy. Since the feeding mechanism 3 is connected to the stamping mechanism 11, if the feeding mechanism 3 returns after feeding the aluminum plate 144 below the stamping mechanism 11, the aluminum plate 144 may spring back when it contacts the limiting plate, resulting in inaccurate positioning. Furthermore, the aluminum plate 144 may move too quickly, causing it to contact the limiting plate too quickly. Damage caused requires manual or other auxiliary equipment to perform secondary positioning or adjustment of the aluminum plate 144. Through the setting of the mounting box 33, the second guide shaft 333 and the second elastic element 334, when the driving block 331 moves the aluminum plate 144 to the limit plate, the slider 31 will continue to move due to the sliding cooperation with the mounting box 33. At this time, the slider 31 will compress the second elastic element 334 located between it and the mounting box 33, so that the aluminum plate 144 can be stably fixed between the driving block 331 and the limit plate. This facilitates the positioning mechanism on the stamping mechanism 11 to fix the aluminum plate 144, making the stamping of the aluminum plate 144 by the stamping mechanism 11 more accurate and improving the quality of the product.

[0064] like Figure 12 and Figure 13 As shown: The inner wall of the discharge port 141 is provided with an inclined groove 1411.

[0065] Since the top feeding mechanism 2 will lift the remaining aluminum plate 144 in the material box 14, the aluminum plate 144 may be unable to move out of the discharge port 141 due to slight warping because there is no aluminum plate 144 pressing it down during the sliding process with the feeding mechanism 3. The inclined groove 1411 can guide the slightly warped aluminum plate 144, making it easier for it to move out of the discharge port 141 and improving the stability of the equipment operation.

[0066] like Figure 1 , Figure 2 and Figure 11As shown: On the frame 1, below the stamping mechanism 11, there are two drive shafts 12 with axes parallel to the axis of the rotating shaft 23. Each drive shaft 12 is fitted with a first gear 121. The stamping mechanism 11 is provided with a stamping plate 13 that can slide in the vertical direction. On both sides of the stamping plate 13, there are racks 131 that are the same number as the drive shafts 12 and correspond one-to-one. The racks 131 and the first gears 121 are meshed and connected. The lead screw 321 of the feeding mechanism 3 is connected to one of the drive shafts 12. Both rotating shafts 23 of the top material mechanism 2 are connected to the drive shafts 12 on the same side.

[0067] The stamping mechanism 11 also includes a linear drive. The stamping plate 13 is connected to the linear drive for transmission. The linear drive drives the stamping plate 13 to slide. The sliding of the stamping plate 13 drives the rack 131 connected to it. The movement of the rack 131 drives the rotation of the first gear 121 meshing with it. The rotation of the first gear 121 drives the drive shaft 12 connected to it. The drive shaft 12 drives the feeding mechanism 3 and the ejector mechanism 2 connected to it. This eliminates the need for additional drive sources. After each stamping operation, the feeding mechanism 3 sends an aluminum plate 144 to the bottom of the stamping mechanism 11. This eliminates the need for intermittent mechanisms, thereby improving the synchronization of multiple mechanisms and increasing the stamping efficiency.

[0068] like Figures 1 to 4 and Figure 10 As shown: The two rotating shafts 23 of the top material mechanism 2 are each provided with a first transmission shaft 231 parallel to their axes. The rotating shafts 23 and the first transmission shafts 231 are each fitted with a second gear 232. The two second gears 232 are meshed and connected. The two first transmission shafts 231 are connected to the drive shaft 12 below the frame 1.

[0069] When the stamping plate 13 presses down on the aluminum plate 144, it drives the first rack 131, which in turn drives the first gear 121 to rotate clockwise. The first rack 131 then drives the drive shaft 12 to rotate clockwise. If the drive shaft 12 directly drives the rotating shaft 23, the ejector mechanism 2 will release the remaining aluminum plate 144 from the material box 14, increasing friction and scratches between the aluminum plates 144. Therefore, when the stamping plate 13 presses down, the drive shaft 12 needs to drive the rotating shaft 23 to rotate in reverse. This is achieved through the arrangement of the first drive shaft 231 and two second gears 232. This causes the drive shaft 12 to drive the first drive shaft 231, which in turn drives the second gear 232. The second gear 232 then drives the second gear 232 that meshes with and is sleeved on the rotating shaft 23. This causes the rotating shaft 23 and the first drive shaft 231 to rotate in opposite directions. Consequently, the rotating shaft 23 and the drive shaft 12 rotate in opposite directions. This causes the ejector mechanism 2 to lift the aluminum plate 144 in the material box 14 during the stamping process. This ensures that the operation of the mechanisms is synchronized and improves the efficiency of the stamping process.

[0070] like Figure 11 As shown: A second drive shaft 323 is provided on the side of the lead screw 321. Two synchronous belts 324 are sleeved on the second drive shaft 323. The two synchronous belts 324 are respectively connected to the lead screw 321 and the drive shaft 12.

[0071] When the lead screw 321 is connected to the drive shaft 12, and slides to the mounting base 32 near the stamping mechanism 11, the mounting box 33 connected to the slider 31 will pass through the mounting base 32. At this time, the timing belt 324 will interfere with the movement of the mounting box 33, thereby affecting the feeding of the drive block 331 in the mounting box 33 to the aluminum plate 144. By setting the second drive shaft 323, the timing belt 324 can avoid the movement path of the mounting box 33, thus improving the stability of the equipment operation.

[0072] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
