Description

Technical Field

[0001] The present invention relates to the technical field of oiling hinge points of folding screens, and particularly to an oiling device for folding screen hinges at multiple angles. Background Art

[0002] A folding screen hinge is an important component of a folding screen device (such as a folding screen mobile phone, a folding screen computer, a folding display screen, etc.). It is used to connect two or more flipping bodies of the folding screen device to realize the unfolding and folding of the folding screen device. The folding screen hinge is assembled from multiple parts. During the assembly process, oil needs to be applied to the joint parts of the parts to reduce the friction between the parts and enable the parts to move relative to each other smoothly. The parts of the folding screen hinge are small in size, there are many oiling positions, and the oiling accuracy requirements are high. Moreover, most of the oiling positions are special-shaped structural surfaces such as grooves and arc surfaces, which makes it difficult to achieve precise oiling of the folding screen parts.

[0003] Currently, the existing oiling solution is as follows: Referring to the patent document (CN219623776U), it discloses a multi-position automatic oiling device for a wire body. This technical solution uses a jig to fix the parts and drives an oiling valve device to move in three axes through a moving mechanism, so that the oiling device can apply oil to the fixed points of the parts on the jig. This solution can only adjust the oiling position in the three-axis direction, but cannot adjust the three-dimensional angle of oiling (such as the oiling inclination), and the oiling accuracy and flexibility are relatively low, which is not suitable for the oiling process of folding screen hinge parts with small size and high oiling accuracy requirements.

[0004] In addition, there are also some oiling solutions: Referring to the patent document (CN213438205U), it discloses a fully automatic multi-station assembly machine. The oiling solution therein is to use a jig to fix the parts and apply oil to the parts on the jig through a swingable oiling device. Although such a solution can adjust the oiling angle by swinging the oiling device, it is still limited to adjusting the angle in a single dimension and cannot achieve multi-directional angle adjustment. The flexibility and oiling accuracy still cannot meet the requirements of folding screen hinge parts for oiling flexibility and accuracy.

[0005] In summary, how to provide an oiling technical solution for folding screen parts with high oiling flexibility and high oiling accuracy is an urgent problem to be solved in the current technical field of oiling folding screen parts. Summary of the Invention

[0051] A multi-angle oiling device for a folding screen hinge provided by the present invention is applied to the process of oiling parts of the folding screen hinge, and can more accurately achieve oiling at multiple positions and at multiple angles, with high oiling flexibility and oiling accuracy.

[0052] Please refer to Figure 1 and Figure 2, The multi - angle oiling device for folding - screen hinges includes at least a material position - adjusting module 20 and a three - axis oiling module 10. Among them, the material position - adjusting module 20 includes a first rotating mechanism 21, a second rotating mechanism 22, and a jig 23 for carrying the material 300. The second rotating mechanism 22 is arranged at the output end of the first rotating mechanism 21. The first rotating mechanism 21 drives the second rotating mechanism 22 to reciprocally flip around the first axis 100. The jig 23 is arranged at the output end of the second rotating mechanism 22. The second rotating mechanism 22 drives the jig 23 to rotate around the second axis 200. The first axis 100 and the second axis 200 are arranged at an angle. For example, the angle between the first axis 100 and the second axis 200 is 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc. In this embodiment, the first axis 100 is perpendicular to the second axis 200. Specifically, the first axis 100 is parallel to the X - axis shown in the drawing, and the second axis 200 is parallel to the Z - axis shown in the drawing.

[0053] Please refer to Figure 3 , The three - axis oiling module 10 includes a three - axis moving platform 11 and an oiling gun 12 arranged at the output end of the three - axis moving platform 11. Among them, the oiling gun 12 can be a commonly used one in the industry. The type, specific structure, and installation method of the oiling gun 12 are not limited here. The configured number of the oiling guns 12 is four. In some other embodiments, the configured number of the oiling guns 12 can be one, two, or more. The specific number is set according to the speed requirements of actual production.

[0054] In this embodiment, the four oiling guns 12 are connected to the output end of the three - axis moving platform 11 through a mounting plate 111. The three - axis moving platform 11 drives the four oiling guns 12 to move synchronously along the X - axis, Y - axis, and Z - axis, so that each oiling gun 12 can oil the material 300 carried by the corresponding jig 23. Among them, the three - axis moving platform 11 is a common moving device in the industry. Some common three - axis moving platforms 11 are composed of three linear modules that respectively complete the moving actions along the X - axis, Y - axis, and Z - axis, so as to achieve the output of three - axis moving actions. The specific structure, installation method, and working principle of the three - axis moving platform 11 are not limited here. Further, it should be understood that the X - axis, Y - axis, and Z - axis in this embodiment are only used as reference coordinates to define the relative position relationship of the structures of the multi - angle oiling device for folding - screen hinges, and do not specifically limit the positions and orientations of the structures of the multi - angle oiling device for folding - screens.

[0055] Next, an example of the application scenario applicable to this embodiment is given:

[0056] In an application scenario, the oiling process for a single oiling position of the material 300 includes: S1. In the initial state, the material 300 is loaded on the fixture 23, with the top surface of the material 300 facing upward and perpendicular to the Z-axis direction; S2. The first rotating mechanism 21 drives the second rotating mechanism 22 as a whole and the fixture 23 to flip by a preset angle around the first axis 100, so that the top surface of the material 300 forms an angle with the Z-axis direction. Synchronously, the second rotating mechanism 22 drives the fixture 23 to rotate by a preset angle around the second axis 200, so that the oiling position of the material 300 faces upward;

[0057] S3. The three-axis moving platform 11 drives the oiling gun 12 to move to directly above the oiling position of the material 300, and then drives the oiling gun 12 to move downward towards the material 300, and the oiling gun 12 performs an oiling operation on the oiling position of the material 300; S4. After the oiling is completed, the oiling gun 12 moves upward, the first rotating mechanism 21 drives the second rotating mechanism 22 as a whole to return to the position corresponding to the initial state, and the second rotating mechanism 22 drives the fixture 23 to return to the position corresponding to the initial state.

[0058] In another application scenario, the oiling process for multiple oiling positions of the material 300 includes: S1. In the initial state, the material 300 is loaded on the fixture 23, with the top surface of the material 300 facing upward and perpendicular to the Z-axis direction; S2. When oiling the first oiling position, the first rotating mechanism 21 drives the second rotating mechanism 22 as a whole and the fixture 23 to flip by a preset angle around the first axis 100, so that the top surface of the material 300 forms an angle with the Z-axis direction. Synchronously, the second rotating mechanism 22 drives the fixture 23 to rotate by a preset angle around the second axis 200. After the above operations, the first oiling position of the material 300 faces upward; S3. The three-axis moving platform 11 drives the oiling gun 12 to move above the first oiling position of the material 300, and then drives the oiling gun 12 to move downward towards the material 300. The oiling gun 12 performs an oiling operation on the first oiling position of the material 300. After the oiling of the first oiling position is completed, the oiling gun 12 moves upward; S4. Continue to oil the second oiling position. The first rotating mechanism 21 drives the second rotating mechanism 22 as a whole and the fixture 23 to flip by a preset angle around the first axis 100, so that the top surface of the material 300 forms an angle with the Z-axis direction. Synchronously, the second rotating mechanism 22 drives the fixture 23 to rotate by a preset angle around the second axis 200. After the above operations, the second oiling position of the material 300 faces upward; S5. The three-axis moving platform 11 drives the oiling gun 12 to move above the second oiling position of the material 300, and then drives the oiling gun 12 to move downward towards the material 300. The oiling gun 12 performs an oiling operation on the second oiling position of the material 300. After the oiling of the second oiling position is completed, the oiling gun 12 moves upward; S6. Continue to oil the third oiling position, and the operation process can refer to the oiling processes of the first oiling position and the second oiling position; S7. And so on. Until after all the oiling positions of the material 300 are oiled, the oiling gun 12 moves upward, the first rotating mechanism 21 drives the second rotating mechanism 22 as a whole to return to the position corresponding to the initial state, and the second rotating mechanism 22 drives the fixture 23 to return to the position corresponding to the initial state.

[0059] In another application scenario, the process of applying oil to the material 300 includes: S1. In the initial state, the material 300 is loaded on the fixture 23, with the top surface of the material 300 facing upward and perpendicular to the Z-axis direction; S2. The first rotating mechanism 21 drives the second rotating mechanism 22 as a whole and the fixture 23 to flip by a preset angle around the first axis 100, so that the top surface of the material 300 forms an angle with the Z-axis direction. Synchronously, the second rotating mechanism 22 drives the fixture 23 to rotate by a preset angle around the second axis 200, so that the oil application position of the material 300 faces upward; S3. The three-axis moving platform 11 drives the oil gun 12 to move to directly above the oil application position of the material 300, and then drives the oil gun 12 to move downward towards the material 300 until the oil on the oil application nozzle of the oil gun 12 contacts the surface of the material 300 corresponding to the oil application position; S4. The first rotating mechanism 21 and / or the second rotating mechanism 22 act to drive the material 300 carried by the fixture 23 to slide relative to the oil gun 12, so that the oil gun 12 can continuously apply oil to the oil application position, for example, apply oil to the oil application position of an arc structure or a linearly extended oil application position or an oil application position on other similar continuous surfaces; S5. After the oil application is completed, the oil gun 12 moves upward, the first rotating mechanism 21 drives the second rotating mechanism 22 as a whole to return to the position corresponding to the initial state, and the second rotating mechanism 22 drives the fixture 23 to return to the position corresponding to the initial state.

[0060] It should be understood that the foregoing listed application scenarios only belong to some application scenarios applicable to the technical solution of the present application. Other applicable application scenarios can be deduced according to the operation principle of the technical solution of the present application, and they are not enumerated one by one here.

[0061] As described above, the multi-angle oil application device for the folding screen hinge of the present application can, based on the actual requirements of the oil application position and angle, adopt the first rotating mechanism 21 and the second rotating mechanism 22 to cooperate to drive the fixture 23 to flip around the first axis 100 and rotate around the second axis 200, so that the material 300 carried by the fixture 23 can flexibly change the position and angle of the material 300 in three-dimensional space, so that the oil application position of the material 300 can accurately face the three-axis oil application module 10; on this basis, the three-axis moving platform 11 drives the oil gun 12 within the X, Y, and Z axes to realize the accurate oil application of the oil gun 12 to the oil application position of the material 300. For application scenarios with multiple oil application positions, the position and angle of the material 300 can be sequentially changed, and oil can be applied to each oil application position in turn. Compared with the prior art, the technical solution of the present application has higher oil application flexibility. In addition, the control of the spatial position and angle of the material 300 is better, which is beneficial to improving the oil application accuracy and solves the technical problems of poor oil application flexibility and low oil application accuracy existing in the prior art.

When the first motor 2121 rotates forward and backward, it can drive the flipping seat 213 to reciprocally flip through the transmission belt 2122. Further, the first motor 2121 is a servo motor, which can real-time feedback its own working signal to the control unit of the device, so that the control unit monitors the rotation process parameters of the first motor 2121 to achieve precise control of the rotation torque, rotation speed, and rotation angle of the first motor 2121.

[0066] The second rotating mechanism 22 is provided on the flipping base 213, and the flipping base 213 drives the entire second rotating mechanism 22 to reciprocally flip around the first axis 100. In some embodiments, the second rotating mechanism 22 includes a second motor fixedly connected to the flipping base 213, and the fixture 23 is detachably provided on the rotating shaft of the second motor. Specifically, the flipping base 213 is provided with a through assembly hole, one end of the fixture 23 is rotatably engaged with the assembly hole, and after the rotating shaft of the second motor penetrates the through hole from the side of the flipping base 213 facing away from the fixture 23, it is connected to the fixture 23 to drive the fixture 23 to rotate relative to the assembly hole. Among them, the second motor can be a servo motor or a stepper motor, and its rotating shaft is connected to the fixture 23 through a fastener. When the fastener is removed, the fixture 23 can be replaced to be suitable for loading different products.

The spider robot can be a common product that can be purchased on the market. This product generally includes a spider robot arm 41, a loading tray 42, and a vision camera system 43. Its working principle is: the spider robot arm 41 grabs the materials 300 on the loading tray 42 one by one and places the materials 300 on the storage seats 441 one by one, while the vision camera system 43 provides visual positioning for the process of the spider robot arm 41 grabbing and placing materials, improving the accuracy of the spider robot arm 41 in grabbing and placing materials. After the spider robot arm 41 places the material 300 on the storage seat 441, the loading module 30 grabs the material 300 on the storage seat 441 and places the material 300 on the fixture 23.

The four turnover mechanisms 312 are all arranged at the output end of the moving mechanism 311, and each turnover mechanism 312 is driven by the moving mechanism 311 to move along the X–Z two axes. Among them, the turnover mechanism 312 can be a cylinder, a servo motor, a stepper motor or other rotatable driving parts. In some embodiments, the configured number of the turnover mechanisms 312 can be one, two or more, and the configured number of the first clamping mechanisms 313 can be one, two or more. At least one first clamping mechanism 313 is arranged on each turnover mechanism 312; and the configured number of the fixtures 23 is the same as that of the turnover mechanisms 312. During the working process, each turnover mechanism 312 can turn over the materials 300 carried by each fixture 23 one by one. In some other embodiments, the moving mechanism 311 can be configured to drive the turnover mechanism 312 to move along three axes, two axes or one axis among the X-Y-Z axes.

[0070] The first clamping mechanism 313 is arranged at the output end of the turnover mechanism 312 and is used to clamp and release the material 300. After the first clamping mechanism 313 clamps the material 300, the turnover mechanism 312 can drive the first clamping mechanism 313 to reciprocally turn over. Among them, the first clamping mechanism 313 includes a first clamp arm group and a first clamping driving part 3131. The first clamping driving part 3131 can be an electric cylinder, a cylinder or other types of driving devices that can drive the first clamp arm group to perform grasping and releasing actions, and it is used to drive the first clamp arm group to clamp and release the material 300. Further, the first clamp arm group is provided with an avoidance space 3133. In some embodiments, the first clamp arm group includes two symmetrically arranged first claw arms 3132. The ends of the first claw arms 3132 form two cantilever parts 3134. The two cantilever parts 3134 of the first claw arms 3132 are spaced apart in the clamping direction of the first clamp arm group, so that an avoidance space 3133 is formed between the two cantilever parts 3134 of the first claw arms 3132. When the first clamp arm group grasps the material 300, the cantilever parts 3134 of the two first claw arms 3132 approach each other to clamp both ends of the material 300. Among them, the shape structure and size of the cantilever part 3134 can be adaptively designed according to the structural characteristics of the actual material 300. Therefore, the shape structure and size of the cantilever part 3134 are not limited herein. In addition, in other embodiments, the number of the cantilever parts 3134 is not limited to two, and its configured number can be adaptively changed according to the grasping requirements of the actual material 300.

[0071] The moving mechanism 311 includes a support frame, a lifting frame, a lifting driving member 3115, a displacement plate 3114, a displacement driving motor 3119, a linkage belt 3117, a pulley set and a linkage shaft 3113. The support frame includes two oppositely arranged vertical plates and a top plate. The bottoms of the two vertical plates are fixedly connected to the workbench 50. The top plate is fixedly connected to the tops of the two vertical plates and is provided with a hollow window. The displacement plate 3114 is slidably arranged on the top surface of the top plate through a guide rail structure, and the displacement plate 3114 is provided with four assembly holes, and each assembly hole is equipped with a guide seat, and the guide seat is provided with a guide hole. The lifting frame constitutes the output end of the moving mechanism 311. The lifting frame includes a substrate 3111 for connecting and supporting the flipping and feeding device 31 and four guide rods 3112 fixedly connected to the bottom surface of the substrate 3111. The four guide rods 3112 are slidably matched with the four guide holes one by one. The lifting driving member 3115 is a cylinder, an electric cylinder or other driving members that can achieve linear telescopic movement. In this embodiment, the lifting driving member 3115 is an electric cylinder. The lifting driving member 3115 is installed on the bottom surface of the displacement plate 3114 and corresponds to the position of the window of the top plate. After the telescopic rod of the lifting driving member 3115 penetrates upward through the displacement plate 3114, it is fixedly connected to the substrate 3111. The pulley set is arranged inside one of the vertical plates. The linkage belt 3117 is sleeved on each pulley of the pulley set, and the linkage belt 3117 is fixedly connected to the bottom surface of the displacement plate 3114 through a connecting frame 3118. The linkage shaft 3113 is located between the two vertical plates, and its two ends are rotatably connected to the two vertical plates. One of the pulleys of the pulley set is sleeved on the linkage shaft 3113. The displacement driving motor 3119 is arranged below the support frame and is fixedly connected to the workbench 50. Linkage wheels are sleeved on the rotating shaft of the displacement driving motor 3119 and the linkage shaft 3113, and the linkage wheel of the displacement driving motor 3119 and the linkage wheel of the linkage shaft 3113 are linked by a belt.

[0072] The driving principle of the moving mechanism 311 is as follows: The displacement driving motor 3119 drives the linkage shaft 3113 to rotate forward and backward through a belt. The linkage shaft 3113 drives the corresponding pulley to rotate forward and backward. The pulley drives the linkage belt 3117 to move forward and backward. The linkage belt 3117 drives the displacement plate 3114 to slide reciprocally along the top surface of the top plate through the connecting frame 3118. The top plate drives the lifting driving member 3115, the lifting frame and the flipping and feeding device 31 to slide synchronously and reciprocally. The lifting driving member 3115 drives the lifting frame to move up and down. The lifting frame drives the entire flipping and feeding device 31 to move up and down, so that the first clamping mechanism 313 and the first clamp arm group of the flipping and feeding device 31 move up and down as a whole.

[0073] Please combine Figure 2 , Figure 3 , Figure 11 and Figure 12。In this embodiment, the material taking device 32 includes four second clamping mechanisms 321. The four second clamping mechanisms 321 are arranged in parallel with the four oiling guns 12 and are arranged staggeredly along the parallel direction. In some other embodiments, the configured number of the second clamping mechanisms 321 can be one, two, or more. The configured number of the second clamping mechanisms 321 is the same as the configured number of the fixtures 23. Each second clamping mechanism 321 can place or pick up the material 300 on each fixture 23 one by one.

[0074] In this embodiment, the material taking device 32 further includes four connecting seats 322. The four second clamping mechanisms 321 are respectively fixed on the mounting plate 111 at the output end of the three-axis moving platform 11 through a connecting seat 322. The second clamping mechanisms 321 are driven by the three-axis moving platform 11 to move along three axes. The second clamping mechanisms 321 are configured to be able to pick up the material 300 and the material 300 on the fixture 23. Among them, the connecting seat is fixed on the mounting plate 111 through a fastener, and the second clamping mechanism 321 is fixed on the connecting seat through a fastener. Of course, in some other embodiments, the connecting seat 322 may not be provided, and the second clamping mechanism 321 is directly fixed on the mounting plate 111 through a fastener. In some other embodiments, the connecting seat 322 can be configured as a driving member capable of performing a lifting action, such as a linear module, a telescopic cylinder, etc. The second clamping mechanism 321 is fixed to the output end of the driving member. In this way, the driving member can finely adjust the upper and lower positions (i.e., the position in the Z-axis direction in the figure) of the second clamping mechanism 321 within a small range, so that the second clamping mechanism 321 can more flexibly adapt to the working processes such as material grasping and placing.

[0075] Further, the second clamping mechanism 321 includes a second arm group and a second clamping driving member 3211. The second clamping driving member 3211 is used to drive the second arm group to clamp and release the material 300. When the first arm group and the second arm group clamp the same material 300, a part of the second arm group is located in the avoidance space 3133 of the first arm group. Of course, in other embodiments, when the first arm group and the second arm group clamp the same material 300, the second arm group can also be entirely located in the avoidance space 3133.

[0076] Specifically, the second clamping driver 3211 is fixedly connected to the mounting plate 111 at the output end of the three-axis moving platform 11 through fasteners. In this embodiment, the second clamping driver 3211 has the same structure as the first clamping driver 3131. Of course, in other embodiments, the structure of the second clamping driver 3211 may also be different from that of the first clamping driver 3131, as long as it can drive the second jaw arm group to grasp and release the material 300. The second jaw arm group includes two symmetrically arranged second jaw arms 3212. In a specific use scenario, the avoidance space 3133 of the first jaw arm group can avoid the end of the second jaw arm 3212, so that when the first jaw arm 3132 clamps the material 300, the second jaw arm 3212 can also clamp the material 300, and the states of the two clamping the material 300 can coexist without interference.

[0077] Next, an exemplary description of the working process of the material taking device 32 and the flipping and discharging device 31 is given:

[0078] The process of the material taking device 32 in this embodiment for grasping and placing the material 300 includes: As Figure 13 shown, driven by the three-axis moving platform 11, the second clamping mechanism 321 first moves from above the fixture 23 to above the storage seat 441, and then moves downward towards the storage seat 441. After moving to the preset position, the second clamping driver drives the corresponding second jaw arm 3212 to clamp the middle part of the material 300, and its clamping direction is along the Y-axis direction. The state after clamping the material is as Figure 14 shown; then, as Figure 15 shown, driven by the three-axis moving platform 11, the second clamping mechanism 321 moves upward and returns to above the fixture 23, and then the three-axis moving platform 11 drives the second clamping mechanism to move downward to the preset position. After that, the moving mechanism 311 drives the first clamping mechanism 313 to move towards the second clamping mechanism 321. When moving to the preset position, the first clamping driver 3131 drives the corresponding first jaw arm 3132 to clamp the two end parts of the material 300. The state after clamping the material 300 is as Figure 16 shown. After that, the second jaw arm 3212 releases the middle part of the material 300, and then the first clamping mechanism 313 moves downward and places the material 300 on the fixture 23. The state after placement is as Figure 17 shown; finally, the first clamping mechanism 313 releases the material 300 and moves upward, and subsequently, the three-axis moving platform 11 drives the oiling gun 12 to perform an oiling operation on the material 300.

[0079] The process of the flipping and discharging device 31 in this embodiment for flipping the material 300 includes: As Figure 15 shown, when the second clamping mechanism 321 grasps the material 300 and is located above the fixture 23, the moving mechanism 311 drives the first clamping mechanism 313 to move towards the second clamping mechanism 321. When moving to the preset position, asFigure 16 As shown, the first clamping driving member 3131 drives the corresponding first jaw arm 3132 to clamp both ends of the material 300, and the second jaw arm 3212 releases the middle part of the material 300. Then, the three-axis moving platform 11 drives the second clamping mechanism 321 to move upward, and then the flipping mechanism 312 drives the first clamping mechanism 313 to flip by a preset angle, such as 180 degrees, so as to flip the material 300. Finally, the second clamping mechanism 321 places the material 300 on the fixture 23, and the placed state is as Figure 17 shown. The position of the material 300 is defined by the fixture 23, so as to perform oiling operation on the back of the material 300 subsequently, enabling the overall device to be applicable to more oiling angles. During the above process, the avoidance space 3133 allows the second jaw arm 3212 to enter, so that the actions of the first jaw arm 3132 and the second jaw arm 3212 clamping the material 300 can be independent of each other. While the first jaw arm 3132 clamps both ends of the material 300, the second jaw arm 3212 can also clamp the middle part of the material 300. Only after one of the second jaw arm 3212 and the first jaw arm 3132 firmly clamps the material 300, the other one releases the material 300. Such a solution enables both of them to have high clamping reliability and clamping accuracy when exchanging the material 300.

[0080] Please continue to refer to Figure 16 and Figure 17 , in this embodiment, a material groove 231 for placing the material 300 and an avoidance groove 232 for avoiding the second clamping arm are provided on the top surface of the fixture 23, and the avoidance groove 232 is communicated with the material groove 231. Among them, the material groove 231 can be adaptively designed according to the shape structure and size of the material 300, as long as it can accommodate and define the material 300. The avoidance groove 232 is located below the material groove 231 and is communicated with the material groove 231, which can facilitate one of the two second clamping arms to move from the avoidance groove 232 to below the material 300, and the other second clamping arm moves to above the material 300, so as to realize the two second clamping arms to clamp the material 300 from the up and down directions.

[0081] In some embodiments, a limit pin can be provided on the material groove 231, and the limit pin can be inserted into the reserved hole position on the material 300, so as to limit the material 300 and prevent the position of the material 300 from shifting during the process of adjusting the angle of the material 300, which affects the oiling accuracy. Of course, in other embodiments, the limit pin can be composed of a magnetic part embedded in the bottom wall or side wall of the material groove 231, and the magnetic part is used to adsorb the material 300, so as to more firmly define the material 300 on the material groove 231.

[0082] In the specific content of the above specific embodiments, the technical features can be combined arbitrarily without contradiction. For the sake of brevity of description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should all be considered to be within the scope described in this specification.

[0083] The specific content of the above specific embodiments only expresses several embodiments of the present invention. Its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be subject to the appended claims.
