Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to adhesive application equipment, systems and methods. Background Technology

[0002] Applying adhesive is a crucial step in the cell / battery stacking process. During stacking, buffer or insulating components, such as foam, are added between individual cells to prevent collisions. The adhesive application process is to adhere these buffer or insulating components and connect the individual cells into a unified whole.

[0003] Depending on the characteristics of different batteries, adhesive application is divided into large-area adhesive application and small-area adhesive application.

[0004] Existing adhesive application mechanisms generally include an unwinding assembly, a winding assembly, a pressing assembly, an adhesive application assembly, a rolling assembly, and a cutting assembly. Large-area adhesive application is mainly for pouch batteries, while small-area adhesive application is for batteries with hard shells. Large-area adhesive application can also be applied to hard-shell batteries.

[0005] During the research and development process, it was found that in the case of large-area adhesive application, the existing adhesive application equipment with the winding component as the traction module has a complex structure. The setting of the winding component can cause the adhesive to be misaligned, so the adhesive application equipment needs to be equipped with a correction mechanism, which affects the production speed and product quality. Summary of the Invention

This saves on the need for a correction module, thereby reducing the number of components, optimizing the overall structure, simplifying the structure, and contributing to improved production speed and product quality.

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0072] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0073] This application discloses an adhesive application device.

[0074] Please see Figure 1 One embodiment of the adhesive application device provided in this application includes:

[0075] The equipment body 100, the adhesive application drive device 400, the traction device 300, and the adhesive application device 200.

[0076] The adhesive application drive device 400 is mounted on the main body 100 and connected to the adhesive application device 200, used to drive the adhesive application device 200 to move. The adhesive application drive device 400 is designed to include at least a first adhesive application drive assembly 401 and a second adhesive application drive assembly 402. The second adhesive application drive assembly 402 can be a cylinder lifting module, etc., connected to the adhesive application device 200, used to drive the adhesive application device 200 to move up and down, so that the adhesive application device 200 can contact the surface of the object to be adhesiveped. The first adhesive application drive assembly 401 can be a cylinder sliding module, etc., connected to the second adhesive application drive assembly 402, used to drive the second adhesive application assembly to move, thereby driving the adhesive application device 200 to perform the adhesive application movement. Taking the adhesive application movement direction as a straight line as an example, then the first adhesive application drive assembly 401 is also a linear drive module.

[0077] The traction device 300 is installed on the main body 100 of the equipment. Specifically, it is set on the same plane as the adhesive applicator 200 along the adhesive applicator movement direction. The traction device 300 and the adhesive applicator 200 can be relatively close or far apart.

[0078] The traction device 300 grips the release layer output by the adhesive applicator 200 and applies a traction force to the release layer in the opposite direction of the applicator's movement during the applicator's application motion. This traction force separates the release layer from the adhesive layer. This linear traction design, compared to traditional winding traction designs, allows for constant traction of the release layer, reducing the offset problem caused by unstable traction direction in winding traction methods. It also solves the problem of offset caused by the overlapping of multiple release layers during winding, resulting in misaligned application. This saves on the need for a correction module, reducing the number of modules, optimizing the overall structure, simplifying the design, and contributing to improved production speed and product quality. It should be noted that the release layer refers to the release layer, release film, or release paper used to separate the adhesive layer; that is, a non-adhesive tape release layer.

[0079] In addition, to improve the mobility of the equipment and facilitate the removal of the tape application device 200 for tape feeding, a device moving device 500 is also included. This device moving device 500 is connected to the main body 100 and is used to move the main body 100. This device moving device 500 can be a linear guide rail device, and its movement direction is the same as the tape application movement direction, that is, the same as the driving direction of the first tape application drive assembly 401. After tape feeding is completed, the device moving device 500 moves the main body 100 to the edge of the battery conveyor line, allowing the tape application device 200 to continue the tape application operation.

[0080] The above is Embodiment 1 of the adhesive application equipment provided in this application. The following is Embodiment 2 of the adhesive application equipment provided in this application. Please refer to the following for details. Figures 1 to 10 .

[0081] Based on the solution of Embodiment 1 above:

[0082] Furthermore, such as Figure 3 As shown, the structural design of the adhesive applicator 200 includes the main body 1, the unwinding mechanism 2, the rolling mechanism 4, the adhesive cutting mechanism 3, and the paper fixing mechanism 5.

[0083] The unwinding mechanism 2 is installed on the main body 1 of the device and is used to release the tape. The unwinding mechanism 2 can be designed with reference to existing unwinding devices or directly adopted.

[0084] The rolling mechanism 4 is installed on the main body 1 of the device and is used to roll the adhesive layer on the released tape onto the surface of the object to be glued, so as to transfer the adhesive layer to the surface of the object to be glued and achieve the purpose of applying adhesive.

[0085] The tape-cutting mechanism 3 is installed on the main body 1 of the device and is used to cut the adhesive layer on the tape to control the length of the tape. The tape-cutting mechanism 3 achieves a state where the adhesive layer is segmented but the release layer remains connected, facilitating the traction device 300 to pull and grasp the tape and preventing adhesive buildup on the traction device 300. In the design, the width of the release layer is greater than the width of the adhesive layer. This allows the release layer area covered by the adhesive layer to be cut along with the tape during tape cutting, resulting in a more thorough cut without completely severing the release layer, thus ensuring that the release layer remains connected.

[0086] The paper-fixing mechanism 5 is installed on the main body 1 of the device and can clamp the isolation layer output by the rolling mechanism 4. The traction device 300 is used to grip the isolation layer clamped on the paper-fixing mechanism 5.

[0087] Of course, the above-mentioned adhesive applicator 200 may also be without the adhesive cutting mechanism 3, that is, it includes the main body of the device 1, the unwinding mechanism 2, the rolling mechanism 4, and the paper fixing mechanism 5.

[0088] The unwinding mechanism 2 is installed on the main body 1 of the device and is used to release the tape. The unwinding mechanism 2 can be designed with reference to existing unwinding devices or directly adopted.

[0089] The rolling mechanism 4 is installed on the main body 1 of the device and is used to roll the adhesive layer on the released tape onto the surface of the object to be glued, so as to transfer the adhesive layer to the surface of the object to be glued and achieve the purpose of applying adhesive.

[0090] The adhesive layer on the isolation layer can be torn off, or it can be pre-cut into segments of a set length, so that the adhesive application can be completed one by one without cutting the adhesive.

[0091] The paper-fixing mechanism 5 is installed on the main body 1 of the device and can clamp the isolation layer output by the rolling mechanism 4. The traction device 300 is used to grip the isolation layer clamped on the paper-fixing mechanism 5.

[0092] The adhesive application process is as follows (taking the adhesive cutting mechanism 3 as an example):

[0093] 1. The traction device 300 grips and clamps the paper-fixing mechanism 5, completing the gripping process;

[0094] 2. The adhesive application drive device 400 drives the adhesive application device 200 to move downwards until the adhesive layer on the rolling mechanism 4 contacts the surface of the object to be adhesiveped. At this time, the adhesive application device 200 is considered to have reached the adhesive application preparation position.

[0095] 3. The adhesive application drive device 400 drives the adhesive application device 200 to move a preset distance away from the traction device 300 to perform adhesive application, so as to press and transfer the adhesive layer to the surface of the object to be adhesiveped. When a certain length of adhesive is applied, the adhesive cutting mechanism 3 cuts the adhesive layer. At the same time, the paper fixing mechanism 5 re-fixes the isolation layer.

[0096] After applying the adhesive, repeat steps 1-3 above to apply the adhesive again.

[0097] By cooperating with the traction device 300 and the adhesive application device 200, integrated adhesive application can be achieved directly, eliminating the need for a separate adhesive supply platform for placing the cut adhesive layer and preventing wrinkles from occurring when the adhesive layer is applied after cutting.

[0098] Furthermore, such as Figure 3 As shown, in order to better grip and recycle the isolation layer, the adhesive applicator 200 also includes a paper cutting mechanism 6.

[0099] The paper cutting mechanism 6 is installed on the main body 1 of the device and can cut the isolation layer clamped on the paper fixing mechanism 5. That is, it can cut the isolation layer segment clamped by the paper fixing mechanism 5 after the isolation layer is separated from the adhesive layer (without the adhesive layer attached), so as to complete the cutting of the isolation layer. With this design, the output isolation layer can be cut after each adhesive application operation to facilitate recycling, and at the same time, it is convenient for the traction device 300 to grab the isolation layer fixed on the paper fixing mechanism 5 again.

[0100] like Figure 1 As shown, the adhesive application equipment also includes a waste bin 600, which is installed on the main body 100 of the equipment and is used to collect the cut isolation layer.

[0101] like Figure 3 as well as Figure 4 As shown, the paper cutting mechanism 6 specifically includes a paper cutting blade 62 and a paper cutting driver 61. The paper cutting driver 61 can be a lifting cylinder or the like, which drives the paper cutting blade 62 to move up and down to complete the cutting of the isolation layer. The paper cutting mechanism 6 may also include a baffle plate 63, which is fixed to the main body 1 of the device and located on the side of the paper cutting blade 62 away from the traction device 300, for the purpose of protecting the paper cutting blade 62.

[0102] Furthermore, such as Figure 3 As shown, the design of the paper-fixing mechanism 5 includes a first paper-fixing assembly 51, a second paper-fixing assembly 53, a first paper-fixing driver 52, and a second paper-fixing driver 54.

[0103] The second paper-fixing assembly 53 is disposed on the side of the first paper-fixing assembly 51 toward the traction device 300, and a paper-cutting gap is formed between the second and first paper-fixing assemblies 51 to avoid the cutting action of the paper-cutting mechanism 6.

[0104] The first paper-fixing driver 52 is connected to the first paper-fixing assembly 51 and is used to drive the first paper-fixing assembly 51 to clamp the isolation layer; the second paper-fixing driver 54 is connected to the second paper-fixing assembly 53 and is used to drive the second paper-fixing assembly 53 to clamp the isolation layer; the gripping part of the traction device 300 can move through the second paper-fixing assembly 53.

[0105] The design of two independently controlled paper-fixing components can fix the isolation layer at intervals, thereby forming a cutting gap that avoids the cutting action of the paper-cutting mechanism 6, ensuring the cutting effect of the paper-cutting mechanism 6. After the cutting is completed, the second paper-fixing component 53 can be controlled to release the cut isolation layer for recycling; while the first paper-fixing component 51 keeps the isolation layer fixed, waiting for the traction device 300 to pass through the second paper-fixing component 53 for gripping.

[0106] Furthermore, such as Figure 3 , Figure 5as well as Figure 6 As shown, the first paper-fixing assembly 51 includes a first paper-fixing fixed pressure head 511 and a first paper-fixing moving pressure head 512.

[0107] The first paper-fixing pressure head 511 is fixed on the main body 1 of the device; the first paper-fixing moving pressure head 512 is fixed on the driving end of the first paper-fixing driver 52 and is clamped and cooperated with the first paper-fixing pressure head 511; the first paper-fixing pressure head 511 may be arranged below the first paper-fixing moving pressure head 512, in a bottom-up arrangement.

[0108] The second paper-fixing assembly 53 includes a second paper-fixing stationary pressure head 531 and a second paper-fixing moving pressure head 532. The second paper-fixing stationary pressure head 531 is fixed on the main body 1 of the device and has a first clearance groove to avoid the gripping portion of the traction device 300. The second paper-fixing moving pressure head 532 is fixed on the driving end of the second paper-fixing driver 54 and has a second clearance groove that corresponds to the first clearance groove and avoids the gripping portion of the traction device 300. The second paper-fixing moving pressure head 532 may be disposed below the second paper-fixing stationary pressure head 531, in a bottom-up arrangement.

[0109] The second paper-fixing fixed pressure head 531 and the second paper-fixing moving pressure head 532 can each be composed of multiple toothed columns to form a comb structure, and a first clearance groove or a second clearance groove can be formed between adjacent toothed columns.

[0110] In order to better fix the isolation layer, the ends of the first paper-fixing fixed pressure head 511 and the first paper-fixing moving pressure head 512 are provided with meshing tooth structures that mesh with each other. Similarly, the ends of the second paper-fixing fixed pressure head 531 and the second paper-fixing moving pressure head 532 are also provided with meshing tooth structures that mesh with each other.

[0111] Furthermore, such as Figure 6 As shown, the paper-fixing mechanism 5 also includes a support head 55 that can support the isolation layer.

[0112] The support pressure head 55 is fixed on the drive end of the second paper-fixing driver 54 and is located on the side of the second paper-fixing moving pressure head 532 away from the traction device 300; the support pressure head 55 is provided with a third clearance groove that corresponds to the second clearance groove and avoids the gripping part of the traction device 300; a cutting gap is formed between the support pressure head 55 and the second paper-fixing moving pressure head 532.

[0113] The design of the support head 55 can support the isolation layer, preventing it from folding downwards after being cut, thus avoiding the problem of the traction device 300 being unable to grip the isolation layer properly. The support head 55 can also be composed of multiple toothed columns, with a third clearance groove formed between adjacent toothed columns to avoid the gripping part of the traction device 300.

[0114] Furthermore, such as Figure 2As shown in Figure 6, the traction device 300 includes a traction gripper assembly 71 and a gripper driver 72. The gripper driver 72 is connected to the traction gripper assembly 71 and is used to drive the traction gripper assembly 71 to grip the isolation layer. The traction gripper assembly 71 consists of an upper gripper 711 and a lower gripper 712, while the gripper driver 72 can be a conventional gripper motor. In order to cooperate with the first clearance groove of the second paper-fixing pressure head 531 and the second clearance groove of the second paper-fixing moving pressure head 532, the gripping parts on the upper gripper 711 and the lower gripper 712 are also composed of multiple toothed pillars. The toothed pillars of the upper gripper 711 can move through the first clearance groove, while the toothed pillars of the lower gripper 712 can move through the second clearance groove. Similarly, in order to better grip the isolation layer, the teeth of the upper gripper 711 and the toothed pillars of the lower gripper 712 are respectively provided with meshing tooth structures that can mesh with each other on the side where they grip and cooperate with each other.

[0115] Taking the traction device 300 without the traction moving component 73 as an example, that is, as follows Figure 2 As shown, the gripper driver 72 is directly mounted on the device body 100 and then connected to the traction gripper assembly 71. In this design, the adhesive application process is as follows:

[0116] 1a. The adhesive application drive device 400 drives the adhesive application device 200 to move towards the traction device 300 to the preset traction preparation position. Then, the traction device 300 grips the isolation layer on the paper fixing mechanism 5 to complete the gripping.

[0117] 2a. The adhesive application drive device 400 drives the adhesive application device 200 to move away from the traction device 300 to above the adhesive application preparation position, and then drives the adhesive application device 200 to move downward until the adhesive layer on the rolling mechanism 4 contacts the surface of the object to be adhesiveped. At this time, it is also considered that the adhesive application device 200 has reached the adhesive application preparation position.

[0118] 3a. The adhesive application drive device 400 drives the adhesive application device 200 to move a preset distance away from the traction device 300 to perform adhesive application, so as to press and transfer the adhesive layer to the surface of the object to be adhesiveped. When a certain length of adhesive is applied, the adhesive cutting mechanism 3 cuts the adhesive layer. At the same time, the paper fixing mechanism 5 re-fixes the isolation layer.

[0119] After applying the adhesive, repeat steps 1a-3a above to proceed with the next application.

[0120] Furthermore, in order to improve the mobility of the traction device 300 and make it more flexible in use, the traction device 300 also includes a traction moving component 73.

[0121] like Figure 1 as well as Figure 7As shown, the traction moving component 73 is mounted on the main body 100 of the device and connected to the gripper driver 72 for driving the gripper driver 72 to move. The traction moving component 73 may include a first traction mover 731 and a second traction mover 732. The first traction mover 731 may be a cylinder lifting module connected to the gripper driver 72 for driving the traction gripper component 71 to move up and down. The second traction mover 732 may be a cylinder slide module connected to the first traction mover 731 for driving the traction moving component 73 to move away from or towards the adhesive applicator 200. Specifically, the driving direction of the second traction mover 732 may be the same as the driving direction of the aforementioned first adhesive applicator driving component 401.

[0122] Taking the traction moving component 73 as an example, the adhesive application process is as follows:

[0123] 1b. The traction gripper assembly 71 of the traction device 300 moves to the gripping position under the drive of the traction moving assembly 73. Under the drive of the gripper driver 72, the gripper assembly 71 grips the isolation layer on the paper fixing mechanism 5 and completes the gripping.

[0124] 2b. The adhesive application drive device 400 drives the adhesive application device 200 to move downwards until the adhesive layer on the rolling mechanism 4 contacts the surface of the object to be adhesiveped. At this time, the adhesive application device 200 is considered to have reached the adhesive application preparation position.

[0125] 3b. The adhesive application drive device 400 drives the adhesive application device 200 to move a preset distance away from the traction device 300 to perform adhesive application, so as to press and transfer the adhesive layer to the surface of the object to be adhesiveped. When a certain length of adhesive is applied, the adhesive cutting mechanism 3 cuts the adhesive layer. At the same time, the paper fixing mechanism 5 re-fixes the isolation layer.

[0126] After applying the adhesive, repeat steps 1b-3b above to proceed with the next application.

[0127] Furthermore, such as Figure 3 As shown, in order to smoothly guide the release layer to the paper-fixing mechanism 5, the adhesive applicator 200 also includes a guide roller 8. The guide roller 8 is installed on the side of the paper-fixing mechanism 5 away from the traction device 300 and above the rolling mechanism 4, and is used to guide the release layer to the paper-fixing mechanism 5. The ends of the guide roller 8 are respectively fixed with stop portions, forming a limiting area for the release layer to pass through, so as to prevent the release layer from shifting.

[0128] Furthermore, the adhesive applicator 200 also includes a paper pressing mechanism 9, which is mounted above the guide roller 8 and can roll and press the release layer on the guide roller 8. Specifically, the paper pressing mechanism 9 includes a paper pressing driver 91 and a paper pressing roller 92; the paper pressing driver 91 is a cylinder lifting module, which is fixedly mounted on the main body 1 and located above the guide roller 8. The paper pressing roller 92 is rotatably mounted on the driving end of the paper pressing driver 91 and forms a clamping gap between itself and the roller shaft of the guide roller 8 for the release layer to pass through. By pressing the release layer, the limiting effect on the release layer is improved, and the release layer is better prevented from shifting.

[0129] Furthermore, such as Figure 9 As shown, the design of the rolling mechanism 4 includes a mechanism body 41 and a rolling roller 42.

[0130] The main body 41 of the mechanism is fixed to the main body 1 of the device, and the rolling roller 42 is rotatably mounted on the main body 41 of the mechanism for rolling the adhesive layer onto the surface of the object to be adhered. Specifically, the rolling mechanism 4 of this application is used to adhere the adhesive layer to the surface of the single cell along the length direction of the single cell.

[0131] Furthermore, the rolling mechanism 4 also includes a leveling roller 43; the leveling roller 43 is rotatably mounted on the main body 1 of the device and is located on the side of the rolling roller 42 towards the traction device 300; the installation height of the leveling roller 43 is higher than that of the rolling roller 42. The leveling roller 43 is used to level the colloid layer, so that the rolling shaft can more evenly adhere the colloid layer to the battery surface, and the installation position of the leveling roller 43 is higher than that of the rolling roller 42 to avoid premature adhesion of the colloid layer before pressing.

[0132] Furthermore, such as Figure 3 as well as Figure 10 As shown, the rubber cutting mechanism 3 is specifically located on the side of the rolling mechanism 4 away from the traction device 300, and is used to cut the rubber layer on the rolling roller 42 of the rolling mechanism 4. It includes a rubber cutting knife 32 and a rubber cutting moving assembly 31.

[0133] The rubber tapping moving assembly 31 is connected to the rubber tapping blade 32 and is used to drive the rubber tapping blade 32 to move and cut the rubber layer. The rubber tapping moving assembly 31 can be a pneumatic slider module, and the rubber tapping blade 32 can be a hook-shaped blade, specifically mounted on the slider of the rubber tapping moving assembly 31. A sensing plate 311 is also mounted on the slider of the rubber tapping assembly. Two sensors 33 are mounted on the main structure of the rubber tapping moving assembly 31 to detect the sensing plate 311 and limit the movement range of the rubber tapping blade 32, thereby ensuring that the rubber tapping blade 32 can cut the rubber layer but will not completely cut the insulating layer. The sensor 33 can be a photoelectric sensor, and the sensing plate 311 can be an opaque sensing plate 311 that can be detected when passing through the sensing groove of the photoelectric sensor 33.

[0134] In addition, this application also discloses an adhesive layer detector 34, which is fixed on the main body 1 of the device and is used to detect whether the tape at the glue application position has an adhesive layer, so as to avoid glue leakage and missed application.

[0135] like Figure 11 As shown, this application also discloses an adhesive application system, including a battery delivery line (not shown) and several adhesive application devices of the above-described Embodiment 1 or Embodiment 2.

[0136] Several adhesive application devices are installed on at least one side of the battery conveyor line for applying adhesive to the batteries on the battery conveyor line. Specifically, there may be multiple adhesive application devices, evenly distributed on both sides of the battery conveyor line.

[0137] Furthermore, the conveying station on the battery conveying line is equipped with a battery lifting mechanism for lifting the battery. By cooperating with the adhesive applicator 200 of the adhesive applicator, the adhesive applicator efficiency can be further improved.

[0138] The adhesive application equipment designed in this application can be used with a battery conveyor line, that is, the adhesive application operation can be completed directly on the battery conveyor line, which effectively simplifies the process and avoids process complexity.

[0139] like Figure 12 This application also discloses an adhesive application method, applied to the aforementioned adhesive application equipment, comprising the following steps:

[0140] S1 controls the traction device to grip the release layer output by the adhesive applicator; it should be noted that, taking the device with traction moving component 73 as an example, the specific steps are as follows:

[0141] The traction moving component 73 of the traction device 300 is controlled to drive the traction gripper component 71 to move to the preset gripping position, and then the gripper driver 72 of the traction device 300 is controlled to drive the gripper component 71 to grip the isolation layer on the paper fixing mechanism 5, thus completing the gripping.

[0142] Taking the absence of the traction moving component 73 as an example, before step S1, it is necessary to control the adhesive application drive device 400 to move the adhesive application device 200 towards the traction device 300 to the preset traction preparation position. Then, control the gripper driver 72 of the traction device 300 to drive the gripper component 71 to grip the isolation layer on the paper fixing mechanism 5 to complete the gripping.

[0143] S2, control the adhesive application drive device to move the adhesive application device to the adhesive application preparation position; it should be noted that, taking the device with traction moving component 73 as an example, that is, the adhesive application device 200 can be in the adhesive application preparation position from the beginning, then the specific steps of S2 can be: control the adhesive application drive device 400 to move the adhesive application device 200 downward until the adhesive layer on the rolling mechanism 4 contacts the surface of the object to be adhesiveped, at which point the adhesive application device 200 is considered to have reached the adhesive application preparation position.

[0144] Taking the absence of the traction moving component 73 as an example, specifically: the adhesive application drive device 400 is controlled to move the adhesive application device 200 away from the traction device 300 to above the adhesive application preparation position, and then the adhesive application device 200 is moved downward until the adhesive layer on the rolling mechanism 4 contacts the surface of the object to be adhesiveped. At this time, it is also considered that the adhesive application device 200 has reached the adhesive application preparation position.

[0145] S3, control the adhesive application drive device to drive the adhesive application device to perform adhesive application movement; it should be noted that, specifically, control the adhesive application drive device 400 to drive the adhesive application device 200 to move a preset distance away from the traction device 300 to perform adhesive application movement, so as to press and transfer the adhesive layer to the surface of the object to be adhesiveped. When a certain length of adhesive is applied, the adhesive cutting mechanism 3 cuts the adhesive layer, and at the same time, the paper fixing mechanism 5 re-fixes the isolation layer.

[0146] The above provides a detailed description of the adhesive application equipment, system, and method provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
