[0002] Currently, during the workpiece production process, tooling is usually used to clamp and fix the workpiece so as to perform operations such as welding and marking on the workpiece.

[0003] When changing production models, tooling needs to be replaced and fixed to meet the production needs of different workpiece models. However, current tooling replacement and fixation require manual operation.

[0040] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The present application provides a tooling automatic disassembly and fixing device 100, which includes a transfer mechanism 30, a lifting mechanism 20 and a clamping mechanism 10, wherein the clamping mechanism 10 has a clamping space 122, and the transfer mechanism 30 is connected to the lifting mechanism 20 in a transmission manner and is used to drive the lifting mechanism 20 to switch between the loading position 300 and the tooling replacement position; when the lifting mechanism 20 is located at the loading position 300, the lifting mechanism 20 is detachably connected to the first tooling 600, and the second tooling 700 is loaded and stacked onto the first tooling 600. When the lifting mechanism 20 is located at the tooling replacement position, the second tooling 700 is partially inserted into the clamping space 122. The lifting mechanism 20 is used to drive the first tooling 600 to lift the second tooling 700 when it is located at the tooling replacement position until the second tooling 700 is positioned and matched with the clamping mechanism 10; the clamping mechanism 10 is used to clamp the second tooling 700 after it is positioned and matched with the second tooling 700, so that the second tooling 700 is fastened in the clamping space 122.

[0041] As an example, the transfer mechanism 30 and the clamping mechanism 10 can be directly mounted on the mounting surface where the tooling automatic disassembly and fixing device 100 is located. Alternatively, the tooling automatic disassembly and fixing device 100 can further include a frame 40 mounted on the mounting surface, and the transfer mechanism 30 and the clamping mechanism 10 are both mounted on the frame 40. For ease of description, the following embodiments are described using the example where the transfer mechanism 30 and the clamping mechanism 10 are both mounted on the frame 40.

[0042] As an example, the loading station 300 may be used only to load both the first tool 600 and the second tool 700 , or the loading station 300 may also be used to load and unload both the first tool 600 and the second tool 700 .

[0043] For the convenience of description, the following embodiments are described by taking the upper loading position 300 for loading and unloading both the first tooling 600 and the second tooling 700 as an example. In this embodiment, all the toolings to be replaced are centrally loaded and unloaded through the same position, which is beneficial to improving the replacement efficiency of the automatic tooling replacement and the fixing device 100.

[0044] Generally, the first tooling 600 refers to the tooling located below the workpiece when in the tooling replacement position, and the second tooling 700 refers to the tooling located above the workpiece when in the tooling replacement position. When the first tooling 600 and the second tooling 700 are fixed at the tooling replacement position, the first tooling 600 and the second tooling 700 cooperate and jointly clamp the workpiece to facilitate subsequent processing operations such as welding and marking of the workpiece.

[0045] The automatic tooling replacement and fixing device 100 has a tooling replacement state and a tooling holding state. The tooling replacement state refers to the state in which the automatic tooling replacement and fixing device 100 is used to replace the tooling, and the tooling holding state refers to the state in which the automatic tooling replacement and fixing device 100 is used to fix the tooling at the tooling replacement position and clamp the workpiece.

[0046] When the tooling needs to be replaced, the automatic tooling replacement and fixing device 100 switches to the tooling replacement state. In the tooling replacement state, the first tooling 600 and the second tooling 700 are stacked on the lifting mechanism 20 in sequence at the upper loading position 300. Then, the transfer mechanism 30 drives the lifting mechanism 20 to drive the first tooling 600 and the second tooling 700 to move to the tooling replacement position. During this process, a part of the second tooling 700 is inserted into the clamping space 122 of the clamping mechanism 10. Next, the lifting mechanism 20 drives the first tooling 600 to lift the second tooling 700 until the second tooling 700 is in positioning cooperation with the clamping mechanism 10. Then, after the clamping mechanism 10 is in positioning cooperation with the second tooling 700, it clamps the second tooling 700 until the second tooling 700 is fastened in the clamping space 122, thereby realizing the fixation of the second tooling 700. After that, the lifting mechanism 20 lifts the first tooling 600 so that the relative positions of the first tooling 600 and the second tooling 700 are fixed, and the first tooling 600 and the second tooling 700 cooperate and jointly clamp the workpiece. At this time, the automatic tooling replacement and fixing device 100 switches to the tooling holding state to facilitate the processing of the workpiece located at the tooling replacement position. During the changeover production, the first tooling 600 and the second tooling 700 need to be replaced. At this time, the automatic tooling replacement and fixing device 100 switches to the tooling replacement state. The clamping mechanism 10 releases the second tooling 700, and the second tooling 700 is supported by the first tooling 600. Then, the transfer mechanism 30 drives the lifting mechanism 20 to drive the first tooling 600 and the second tooling 700 back to the upper loading position 300 to facilitate the replacement of the first tooling 600 and the second tooling 700.

[0047] It can be seen that in the present application, by designing the transfer mechanism 30, the lifting mechanism 20 and the clamping mechanism 10, the transfer mechanism 30 can realize the transfer of the first tooling 600 and the second tooling 700 between the loading position 300 and the tooling replacement position, so as to facilitate the rapid replacement of the first tooling 600 and the second tooling 700. The tooling change method is simple and easy to operate. The cooperation between the lifting mechanism 20 and the clamping mechanism 10 can fix the first tooling 600 and the second tooling 700, and the operation is simple and convenient.

[0048] In some alternative embodiments, there are multiple tooling replacement positions which are arranged at intervals along the direction Y from the loading position to the tooling replacement position; when the tooling automatic disassembly and fixing device 100 is in the tooling disassembly and replacement state, the transfer mechanism 30 is used to drive the lifting mechanism 20 to switch between the loading position 300 and each tooling replacement position, so as to transfer the second tooling 700 corresponding to each tooling replacement position to the corresponding tooling replacement position for clamping.

[0049] Wherein, the lifting direction X intersects with the direction Y from the loading position to the tooling replacement position, for example, the lifting direction X is perpendicular to the direction Y from the loading position to the tooling replacement position.

[0050] As an example, different machining operations can be performed at different tooling replacement positions, or different machining processes of the same machining operation can also be performed.

[0051] Specifically, the number of the second tooling 700 and the clamping mechanism 10 is the same as the number of the tooling replacement positions and they correspond one by one, but all the tooling replacement positions share the same first tooling 600. According to the different machining operations or machining processes of the tooling replacement positions, the structures of the first tooling 600 and the second tooling 700 may also need to be changed.

[0052] For the convenience of description, the following embodiments will be described by taking two tooling replacement positions as an example, and different welding processes are performed at the two tooling replacement positions to form different weld tracks on the workpiece (such as stacked cathode plates and anode plates).

[0053] In this embodiment, the second tooling 700 corresponding to two different tooling replacement positions has different weld avoidance grooves, and different weld tracks can be formed by using the laser emitted by the laser welding device through the weld avoidance grooves on different second tooling 700.

[0054] Two tool changing positions, namely tool changing position 400 and second tool changing position 500, are successively set in the direction Y pointing from the loading position to the tool changing position. When the automatic tool changing and fixing device 100 is in the tool changing state, the second tool 700 at the tool changing position 400 and the second tool changing position 500 are successively changed. When the automatic tool changing and fixing device 100 is in the tool holding state, the first tool 600 and the second tool 700 corresponding to the tool changing position 400 or the second tool changing position 500 cooperate to clamp the workpiece for machining the workpiece.

[0055] The specific process is as follows: After loading the first tool 600 and the second tool 700 corresponding to the tool changing position 400 at the loading position 300, the first tool 600 and the second tool 700 corresponding to the tool changing position 400 are transferred to the tool changing position 400, and the second tool 700 corresponding to the tool changing position 400 is clamped and fixed at the tool changing position 400. Then, the transfer mechanism 30 and the lifting mechanism 20 drive the first tool 600 to return to the loading position 300, load the second tool 700 corresponding to the second tool changing position 500, and move it to the second tool changing position 500 for clamping and fixing the second tool 700 corresponding to the second tool changing position 500.

[0056] Next, the transfer mechanism 30 and the lifting mechanism 20 drive the first tool 600 to carry the workpiece through the tool changing position 400 and the second tool changing position 500 in sequence. When the workpiece is at the tool changing position 400, the first tool 600 and the second tool 700 clamp the workpiece at the tool changing position 400 to form a first weld track on the workpiece (the first weld track is as shown in Figure 14 ). When the workpiece is at the second tool changing position 500, the first tool 600 and the second tool 700 clamp the workpiece at the second tool changing position 500 to form a second weld track on the workpiece (the second weld track is as shown in Figure 15 ). The first weld track and the second weld track on the workpiece combine to form a total weld track (the total weld track is as shown in Figure 13 ).

[0057] After that, the workpiece is removed, and the transfer mechanism 30 and the lifting mechanism 20 act together to drive the first tool 600 to carry the second tool 700 at the second tool changing position 500 and the second tool 700 at the tool changing position 400 to move to the loading position 300 for unloading in sequence.

[0058] Specifically, the loading and unloading processes of the first tool 600, the second tool 700 corresponding to the tool changing position 400, and the second tool 700 corresponding to the second tool changing position 500 can refer to the above description and will not be elaborated here.

[0059] In the present application, by providing a plurality of tooling replacement positions, it is convenient to perform sequential machining on the workpiece at the plurality of tooling replacement positions, reducing the machining difficulty at the same tooling replacement position.

[0060] In some alternative embodiments, the transfer mechanism 30 can be a cylinder, an electric cylinder, etc. for linear reciprocating motion drive. The transfer mechanism 30 is a conventional design in the art and will not be elaborated here specifically.

[0061] Please refer to Figures 1 to 6 、 Figures 11 to 12 In some alternative embodiments, the clamping mechanism 10 includes a first clamping plate 11, a second clamping plate 12 and a clamping driving member 13. The first clamping plate 11 and the second clamping plate 12 are arranged at intervals along the lifting direction X and define a clamping space 122. A first positioning portion 121 is formed on the surface of the second clamping plate 12 facing the clamping space 122. The clamping driving member 13 is in transmission connection with the first clamping plate 11. After the second tooling 700 is in positioning cooperation with the first positioning portion, the clamping driving member 13 drives the first clamping plate 11 to move along the lifting direction X until the first clamping plate 11 cooperates with the second clamping plate 12 to clamp the second tooling 700.

[0062] As an example, the clamping driving member 13 can be a cylinder, a servo motor, etc., which can be specifically set according to requirements.

[0063] As an example, the first positioning portion 121 is a positioning pin shaft. The second tooling 700 has a first matching portion that matches with the first positioning portion 121. The first matching portion can be a positioning hole, a positioning groove, etc. The first positioning portion 121 is inserted into the first matching portion to achieve the positioning cooperation between the clamping mechanism 10 and the second tooling 700.

[0064] As an example, in the same clamping mechanism 10, both the first clamping plate 11 and the clamping driving member 13 are one, or both the first clamping plate 11 and the clamping driving member 13 are two and are connected in one-to-one correspondence, and the two first clamping plates 11 are arranged along the direction Z. The direction Z intersects with both the lifting direction X and the direction Y from the loading position to the tooling replacement position. The two first clamping plates 11 in the same clamping mechanism 10 cooperate with one second clamping plate 12 to be able to clamp both ends of the second tooling 700 to improve the clamping stability.

[0065] As an example, the second clamping plates 12 of the respective clamping mechanisms 10 corresponding to the respective tooling replacement positions can be independently provided, or the second clamping plates 12 of the respective clamping mechanisms 10 corresponding to the respective tooling replacement positions are connected to form an integral plate structure. Taking the second clamping plates 12 of the respective clamping mechanisms 10 corresponding to the respective tooling replacement positions being connected to form an integral plate structure as an example, the direction Y from the loading position to the tooling replacement position is the length direction of the integral plate structure, the lifting direction X is the thickness direction of the integral plate structure, and the direction Z is the width direction of the integral plate structure.

[0066] As an example, the rack 40 may include two side frames. The integral plate structure is assembled between the two side frames and forms a structure similar to a gantry with the two side frames, which has high stability. During the clamping process of the second tooling 700, the integral plate structure provides overall support for the large plate and is not easily deformed.

[0067] Next, taking the clamping of both ends of the second tooling 700 by the clamping mechanism 10 as an example for illustration.

[0068] Among them, the second tooling 700 includes a clamping portion 720 and mounting portions 710 provided at opposite ends of the clamping portion 720. When the transfer mechanism 30 drives the lifting mechanism 20 to move along the direction Y from the loading position to the tooling replacement position to the tooling replacement position, the two mounting portions 710 of the second tooling 700 are respectively inserted into the clamping space 122 formed between the second clamping plate 12 and the two first clamping plates 11. Then, the lifting mechanism 20 lifts the second tooling 700 until the first positioning portion 121 on the first clamping plate 11 is inserted into the first mating portion on the second tooling 700. Next, the clamping driving member 13 drives the connected first clamping plate 11 to move along the lifting direction X, so that the first clamping plate 11 can push the second tooling 700 towards the second clamping plate 12 until the mounting portion 710 of the second tooling 700 is pressed against the second clamping plate 12. At this time, the mounting portion 710 on the second tooling 700 is clamped by the first clamping plate 11 and the second clamping plate 12, thus achieving the purpose of clamping and fixing the second tooling 700.

[0069] When unloading the second tooling 700, the clamping driving member 13 drives the connected first clamping plate 11 to descend, and the second tooling 700 is lifted by the first tooling 600 again. Then, under the action of the transfer mechanism 30, the second tooling 700 follows the lifting mechanism 20 back to the loading position 300 for unloading.

[0070] It is worth mentioning that during the whole process, the clamping portion 720 is always located in the gap formed by the spaced-apart two first clamping plates 11 and protrudes from the side of the first clamping plate 11 facing the lifting mechanism 20, so that the clamping portion 720 can cooperate with the first tooling 600 to clamp the workpiece for processing operations later, or the clamping portion 720 can be lifted by the first tooling 600.

[0071] In this embodiment, by providing the first clamping plate 11, the second clamping plate 12 and the clamping driving member 13, it is beneficial to release or clamp and fix the second tooling 700, and improve the reliability of the replacement of the second tooling 700. And the design of the first positioning portion 121 to position the second tooling 700 before clamping and fixing the second tooling 700 helps to reduce the risk of shaking during the clamping process of the second tooling 700 and ensures the installation accuracy of the clamping.

[0072] Please refer toFigure 1 , Figure 2 and Figure 7 , in some alternative embodiments, the clamping mechanism 10 further includes a buffer member 14, and the buffer member 14 is disposed on the surface of the first clamping plate 11 facing the clamping space 122. For example, a buffer member 14 is disposed on the surface of each first clamping plate 11 facing the clamping space 122 defined thereby.

[0073] As an example, the buffer member 14 may be a sponge, rubber, silica gel, etc., and may be specifically selected according to needs.

[0074] When the buffer member 14 is disposed on the surface of the first clamping plate 11 facing the clamping space 122, when the first clamping plate 11 moves along the jacking direction X and contacts the mounting portion 710 of the second tooling 700, the impact of the first clamping plate 11 on the mounting portion 710 can be weakened, which is beneficial to extending the service life of the clamping mechanism 10 and the second tooling 700.

[0075] In some alternative embodiments, any one of a groove 111 or a protrusion 41 is formed on the surface of the first clamping plate 11 facing the clamping space 122, and the other of the groove 111 or the protrusion 41 is formed on the surface of the second clamping plate 12 facing the clamping space 122, or the other of the groove 111 or the protrusion 41 is formed on a portion of the frame 40 extending into the clamping space 122; when the first clamping plate 11 moves along the jacking direction X, the protrusion 41 is inserted into the groove 111. For example, each first clamping plate 11 has a groove 111, and the frame 40 is formed with protrusions 41 corresponding to the grooves 111 on each first clamping plate 11 one by one.

[0076] During the process that the clamping driving member 13 drives the first clamping plate 11 to move along the jacking direction X, the protrusion 41 and the groove 111 are inserted into each other, which can reduce the risk of shaking during the movement of the first clamping plate 11, is beneficial to improving the movement stability of the first clamping plate 11, and accordingly, the reliability of clamping and fixing and the clamping accuracy are also improved.

[0077] Please refer to Figure 1 and Figure 2 , in some alternative embodiments, the clamping mechanism 10 further includes a guide rail 15 and a slider 16. The guide rail 15 is disposed on the frame 40 and extends along the jacking direction X. The slider 16 is slidably mounted on the guide rail 15, and the first clamping plate 11 is connected to the slider 16. For example, the first clamping plate 11 and the slider 16 may be directly connected, or the first clamping plate 11 and the slider 16 may be connected through a mounting plate 17.

[0078] The first clamping plates 11 correspond to the guide rails 15 one by one, and the first clamping plates 11 slide under the guidance of their respective corresponding guide rails 15. The arrangement of the guide rail 15 and the slider 16 further improves the movement stability of the first clamping plate 11.

[0079] Please refer to Figures 8 to 9 Figures 8 to 9 , in some alternative embodiments, the clamping mechanism 10 further includes a fixing frame 18 and an elastic member 19. The fixing frame 18 is fixed to the machine frame 40, the clamping driving member 13 is mounted on the fixing frame 18, and the elastic member 19 is elastically abutted between the fixing frame 18 and the first clamping plate 11 along the lifting direction X. The elastic member 19 is used to provide a pre-tightening force that causes the first clamping plate 11 to have a tendency to move towards the second clamping plate 12.

[0080] The direction of the first clamping plate 11 towards the second clamping plate 12 is the same as the lifting direction X.

[0081] As an example, the elastic member 19 can be a compression spring, silica gel or other elastic components.

[0082] During the process that the transfer mechanism 30 drives the lifting mechanism 20, the first tooling 600 and the second tooling 700 to move from the loading position 300 to the tooling replacement position, the clamping driving member 13 is in the retracted state, and the elastic member 19 is further compressed, so as to form a larger clamping space 122 between the first clamping plate 11 and the second clamping plate 12, thereby facilitating the insertion of the installation portion 710 of the second tooling 700. After the lifting mechanism 20, the first tooling 600 and the second tooling 700 move to the tooling replacement position, the lifting mechanism 20 lifts the first tooling 600 and the second tooling 700, and the first positioning portion 121 of the second clamping plate 12 is inserted into the first mating portion of the second tooling 700. Then, the clamping driving member 13 switches to the clamping state. At the same time, the elastic member 19 rebounds, the first clamping plate 11 is lifted, and the first clamping plate 11 and the second clamping plate 12 clamp and fix the second tooling 700. By providing the clamping driving member 13 and the elastic member 19, the clamping driving member 13 and the elastic member 19 can provide double guarantees for the clamping of the second tooling 700 to prevent the second tooling 700 from falling off.

[0083] It is worth mentioning that after the second tooling 700 is clamped, the elastic member 19 is always in a compressed state and always has a pre-tightening force on the second tooling 700. Therefore, even if the action of the clamping driving member 13 fails, the second tooling 700 will not fall off due to its own weight. In addition, the pre-tightening force of the elastic member 19 is greater than the gravity of the second tooling 700, and the driving force for the clamping driving member 13 to drive the first clamping plate 11 to lift or lower is greater than the pre-tightening force of the elastic member 19. Therefore, when the clamping driving member 13 drives the first clamping plate 11 to descend and unloads the second tooling 700, the clamping driving member 13 can overcome the pre-tightening force of the elastic member 19 so that the second tooling 700 can fall back.

[0084] Please refer to Figure 1 and Figure 10, in some alternative embodiments, the lifting mechanism 20 includes a lifting driving member 21 and a bearing plate 22. The bearing plate 22 has a bearing side, and the lifting driving member 21 is configured to drive the bearing plate 22 to lift the first tooling 600 and the second tooling 700 when the lifting mechanism 20 is located at the tooling replacement position.

[0085] As an example, the lifting driving member 21 can be a cylinder, a servo motor, etc.

[0086] When the tooling automatic disassembly and fixing device 100 is in the tooling replacement state, the lifting driving member 21 increases the driving force for lifting the first tooling 600 and the second tooling 700. When the tooling automatic disassembly and fixing device 100 is in the tooling holding state, the lifting driving member 21 increases the driving force for lifting the first tooling 600 and the workpiece.

[0087] The lifting mechanism 20 having the lifting driving member 21 and the bearing plate 22 has a simple structure and a stable and reliable lifting process.

[0088] In some alternative embodiments, a second positioning portion protruding from the bearing side and configured to be in positioning cooperation with the first tooling 600 is formed on the bearing plate 22.

[0089] As an example, the second positioning portion is a positioning pin shaft. The first tooling 600 has a second mating portion that mates with the second positioning portion. The second mating portion can be a positioning hole, a positioning groove, etc. The second positioning portion is inserted into the second mating portion to achieve the positioning of the first tooling 600.

[0090] During actual operation, the first tooling 600 is first fixed to the lifting mechanism 20 by the cooperation of the second positioning portion and the second mating portion, and then locked to the bearing plate 22 by a detachable member such as a bolt.

[0091] By providing the second positioning portion, the loaded first tooling 600 can be limited, facilitating subsequent locking of the first tooling 600. After the first tooling 600 is fixed, to facilitate loading of the second tooling 700 and enable limiting of the second tooling 700, a third positioning portion 610 can be provided on the first tooling 600, and the second tooling 700 has a third mating portion that mates with the third positioning portion 610. The cooperation of the third positioning portion 610 and the third mating portion is beneficial for limiting the second tooling 700, thereby reducing the risk of the second tooling 700 falling during the transfer between the loading position 300 and the tooling replacement position.

[0092] In some alternative embodiments, the lifting mechanism 20 further includes a leveling transition plate 27. The leveling transition plate 27 is stacked on the bearing side of the bearing plate 22, and the first tooling 600 is supported on the top surface of the leveling transition plate 27 facing away from the bearing plate 22. The leveling transition plate 27 is beneficial to improving the levelness of the loading of the first tooling 600 and the second tooling 700, so that the first tooling 600 and the second tooling 700 can be attached to the workpiece and clamp the workpiece subsequently.

[0093] In some alternative embodiments, the lifting mechanism 20 further includes a mounting frame 23, a linear bearing 24 and a guiding column 25. The linear bearing 24 and the lifting driving member 21 are both mounted on the mounting frame 23, and the guiding column 25 passes through the linear bearing 24 and is connected to the bearing plate 22.

[0094] Specifically, the mounting frame 23 is mounted on the machine frame 40, and mounting holes are formed in the mounting frame 23. The linear bearing 24 is mounted in the mounting holes. The guiding column 25 passes through the linear bearing 24 and is connected to the bearing plate 22. The linear bearing 24 and the guiding column 25 are used in combination, and there can be multiple sets of the linear bearing 24 and the guiding column 25 to support multiple positions of the bearing plate 22, so as to improve the stability of the lifting of the bearing plate 22.

[0095] In some alternative embodiments, the lifting mechanism 20 further includes a pressure detection member 26 and a controller. The pressure detection member 26 is arranged on the lifting driving member 21 and is electrically connected to the controller. The pressure detection member 26 is used to detect the lifting pressure of the lifting driving member 21 and feedback it to the controller. The controller is used to control the lifting driving member 21 to reduce its output lifting pressure when the lifting pressure detected by the pressure detection member 26 exceeds the pressure threshold, so as to avoid too fast lifting speed of the first tooling 600 and / or the second tooling 700 and form a large impact force, ensuring the normal operation of the automatic tooling replacement and fixing device 100. The setting of the pressure detection member 26 is also beneficial to realizing the monitoring of the lifting pressure of the lifting mechanism 20, with a higher degree of automation.

[0096] As Figure 2 shown, in some alternative embodiments, the automatic tooling replacement and fixing device 100 further includes a position detection member 50. The position detection member 50 is mounted on the machine frame 40 and is electrically connected to the controller. The position detection member 50 is used to detect whether the lifting mechanism 20 moves to the tooling replacement position and feedback it to the controller. The controller is used to control the lifting mechanism 20 to lift the first tooling 600 and the second tooling 700 when the lifting mechanism 20 moves to the tooling replacement position. The setting of the position detection member 50 is beneficial to realizing the automatic monitoring of the position where the lifting mechanism 20 is located, so that the lifting mechanism 20 can make corresponding feedback in a timely manner at the corresponding position.

[0097] The above-mentioned automatic tool changing and fixing device 100 can realize the transfer of the first tool 600 and the second tool 700 between the loading position 300 and the tool changing position by designing the transfer mechanism 30, the lifting mechanism 20 and the clamping mechanism 10, so as to facilitate the rapid replacement of the first tool 600 and the second tool 700. The tool changing method is simple and easy to operate. The cooperation of the lifting mechanism 20 and the clamping mechanism 10 can realize the positioning and installation of the first tool 600 and the second tool 700, and the operation is simple and convenient.

[0098] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
