Description

Technical Field

[0001] This application relates to the field of photovoltaic module processing technology, and in particular to a flower basket lifting device. Background Technology

[0002] Flower baskets are key carriers in the photovoltaic module production process, used to carry silicon wafers. With the help of conveyors, flower baskets can be automatically transferred between various processes, avoiding problems such as pollution and debris caused by manual handling.

[0003] During the wafer sizing process, the wafer basket is conveyed to a basket lifting device, which drives the basket to rise and fall. The wafer pick-and-place mechanism extends into the basket to remove the silicon wafers one by one, or to place a single silicon wafer into the basket. However, during debugging and manual operation, operators may activate the basket lifting device before the wafer pick-and-place mechanism has retracted. If the basket lifting device rises and falls excessively, the wafer pick-and-place mechanism may be damaged by the basket lifting device, affecting its normal wafer pick-and-place operation. Utility Model Content

[0004] Therefore, it is necessary to provide a flower basket lifting device to prevent the leaf picking and placing mechanism from being damaged.

[0005] A flower basket lifting device includes:

[0006] The lifting mechanism is equipped with a mounting frame;

[0007] A first fixing mechanism and a second fixing mechanism are both disposed on the mounting frame. A lifting mechanism drives the first fixing mechanism and the second fixing mechanism to move up and down along a first direction of the mounting frame. The first fixing mechanism and the second fixing mechanism are spaced apart along the first direction. The first fixing mechanism and the second fixing mechanism cooperate to clamp the flower basket. At least one of the first fixing mechanism and the second fixing mechanism is movable relative to the mounting frame along the first direction.

[0008] The detection mechanism is used to detect the movement range of at least one of the first fixing mechanism and the second fixing mechanism.

[0009] In one embodiment, the mounting bracket includes a first mounting base, a second mounting base, and a connector. The first mounting base and the second mounting base are opposite to each other and spaced apart in a first direction. The connector is connected to the first mounting base, the second mounting base, and the lifting mechanism. The first fixing mechanism is movably disposed on the first mounting base, and the second fixing mechanism is movably disposed on the second mounting base.

[0010] In one embodiment, the first fixing mechanism includes a support platform and a first elastic member. The support platform is used to support the flower basket, and the first elastic member is disposed between the support platform and the first mounting base. The first elastic member is used to support the support platform and drive the support platform to reset.

[0011] In one embodiment, the support platform has a base on the side opposite to the second fixing mechanism. The base is located between the support platform and the first mounting seat. One end of the first elastic member is connected to the support platform, and the other end of the first elastic member is connected to the base.

[0012] In one embodiment, the detection mechanism includes a pressure sensor disposed on the base, with one end of the first elastic member facing away from the support platform connected to the pressure sensor; or, the pressure sensor is disposed on the support platform, with one end of the first elastic member facing away from the base connected to the pressure sensor; and / or, the detection mechanism includes a proximity sensor disposed on one of the support platform and the base.

[0013] In one embodiment, one of the base and the support platform is provided with a protrusion, and the other of the base and the support platform is provided with a first guide sleeve, which is sleeved on the protrusion and can move relative to the protrusion in the first direction; and / or, the flower basket lifting device further includes a first driving member, which is disposed on the mounting frame, is drivenly connected to the base, and is used to drive the base to move in the first direction.

[0014] In one embodiment, the flower basket lifting device further includes a conveying mechanism disposed on the mounting frame for conveying the flower basket to the support platform; and / or, the flower basket lifting device further includes a stop assembly disposed on the mounting frame and located downstream of the support platform along the conveying direction of the flower basket.

[0015] In one embodiment, the second fixing mechanism includes a second driving member, a pressing member, and a second elastic member. The second driving member is connected to the pressing member and is used to drive the pressing member to move toward or away from the first fixing mechanism. One end of the second elastic member is connected to the second driving member, and the other end of the second elastic member is connected to the second mounting base. The second elastic member is used to press against the second driving member and drive the second driving member to reset.

[0016] In one embodiment, the detection mechanism includes a proximity sensor disposed on one of the second drive member and the second mounting base; and / or, the detection mechanism includes a pressure sensor disposed on the second mounting base, with one end of the second elastic member facing away from the second drive member connected to the pressure sensor; or, the pressure sensor is disposed on the second drive member, with one end of the second elastic member facing away from the second mounting base connected to the pressure sensor.

[0018] In operation, the aforementioned flower basket lifting device places the flower basket between the first and second fixing mechanisms, which then clamp the basket in place. The lifting mechanism then drives both the first and second fixing mechanisms to move along a first direction, causing the flower basket to move synchronously. When the lifting mechanism rises excessively in the first direction, the pick-and-place mechanism presses against the lower surface of the flower basket, causing the first fixing mechanism to move away from the second fixing mechanism. And / or, when the lifting mechanism descends excessively in the first direction, the pick-and-place mechanism presses against the upper surface of the flower basket, causing the second fixing mechanism to move away from the first fixing mechanism. A detection mechanism is included to detect the movement amplitude of at least one of the first and second fixing mechanisms. When the movement amplitude exceeds a predetermined value, the lifting mechanism is stopped, thus protecting the pick-and-place mechanism and preventing damage to it. Attached Figure Description

Detailed Implementation

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] See Figure 1 , Figure 2 and Figure 3 An embodiment of this application provides a flower basket lifting device, including a lifting mechanism 10, a first fixing mechanism 20, and a second fixing mechanism 30. The lifting mechanism 10 is provided with a mounting frame 11, and the first fixing mechanism 20 and the second fixing mechanism 30 are both provided on the mounting frame 11. The lifting mechanism 10 is used to drive the first fixing mechanism 20 and the second fixing mechanism 30 to move along a first direction of the mounting frame 11. Herein, S represents the first direction of the mounting frame 11.

[0030] See Figure 1 , Figure 2 and Figure 3 The first fixing mechanism 20 and the second fixing mechanism 30 are arranged opposite to each other and spaced apart in the first direction. The first fixing mechanism 20 and the second fixing mechanism 30 cooperate to clamp the flower basket 80.

[0031] During operation, the flower basket 80 is placed between the first fixing mechanism 20 and the second fixing mechanism 30. The first fixing mechanism 20 and the second fixing mechanism 30 cooperate to clamp the flower basket 80, thus fixing the flower basket 80. Then, the lifting mechanism 10 drives the first fixing mechanism 20 and the second fixing mechanism 30 to rise and fall, thereby causing the flower basket 80 to rise and fall synchronously.

[0032] When the wafer pick-and-place mechanism 90 rises or falls to a certain height, it extends into the wafer pick-and-place mechanism 80 to remove the silicon wafers one by one or place a single silicon wafer into the wafer pick-and-place mechanism 80. However, during debugging and manual operation, operators may activate the lifting mechanism 10 before the wafer pick-and-place mechanism 90 is retracted. If the lifting mechanism 10 rises or falls excessively, the wafer pick-and-place mechanism 90 may be damaged by the first fixing mechanism 20 and the second fixing mechanism 30, affecting the normal wafer pick-and-place mechanism 90's function. The wafer pick-and-place mechanism 90 is a wafer pick-and-place tongue.

[0033] Therefore, in this embodiment, at least one of the first fixing mechanism 20 and the second fixing mechanism 30 is movably disposed on the mounting frame 11. It is understood that at least one of the first fixing mechanism 20 and the second fixing mechanism 30 is capable of moving in the first direction.

[0034] During operation, the lifting mechanism 10 drives the first fixing mechanism 20 and the second fixing mechanism 30 to move upward, thereby causing the flower basket 80 to move upward synchronously. When the picking and placing mechanism 90 contacts the lower end face 82 of the flower basket 80, the lifting mechanism 10 continues to drive the first fixing mechanism 20, the second fixing mechanism 30, and the flower basket 80 to move upward. Then, the picking and placing mechanism 90 will press against the lower end face 82 of the flower basket 80, causing the first fixing mechanism 20 to move in a direction away from the second fixing mechanism 30.

[0035] Similarly, the lifting mechanism 10 drives the first fixing mechanism 20 and the second fixing mechanism 30 to move downwards, thereby causing the flower basket 80 to move downwards synchronously. When the picking and placing mechanism 90 contacts the upper end surface 81 of the flower basket 80, the lifting mechanism 10 continues to drive the first fixing mechanism 20, the second fixing mechanism 30, and the flower basket 80 to move downwards. Then, the picking and placing mechanism 90 will press against the upper end surface 81 of the flower basket 80, causing the second fixing mechanism 30 to move in a direction away from the first fixing mechanism 20.

[0036] In one embodiment, see Figure 4 , Figure 5 and Figure 6The flower basket lifting device also includes a detection mechanism 40, which is used to detect the movement range of at least one of the first fixing mechanism 20 and the second fixing mechanism 30. It should be noted that the movement range refers to the distance moved in the first direction. By setting up the detection mechanism 40, it can detect the movement range of at least one of the first fixing mechanism 20 and the second fixing mechanism 30. When the movement range exceeds a predetermined value, it controls the lifting mechanism 10 to stop operating, thus protecting the picking and placing mechanism 90 and preventing damage to it.

[0037] In one embodiment, see Figure 7 The mounting bracket 11 includes a first mounting base 111, a second mounting base 112, and a connector 113. The first mounting base 111 and the second mounting base 112 are positioned opposite each other and spaced apart in a first direction. The connector 113 is connected to the first mounting base 111, the second mounting base 112, and the lifting mechanism 10. Specifically, one side of the connector 113 is connected to the lifting mechanism 10, and the other side of the connector 113 is provided with the first mounting base 111 and the second mounting base 112.

[0038] Further, see Figure 2 and Figure 7 The first fixing mechanism 20 is movably disposed on the first mounting base 111, and the second fixing mechanism 30 is movably disposed on the second mounting base 112. Specifically, the first fixing mechanism 20 is disposed on the side of the first mounting base 111 facing the second mounting base 112, and the second fixing mechanism 30 is disposed on the side of the second mounting base 112 facing the first mounting base 111. In this way, the first mounting base 111 provides an installation position for the first fixing mechanism 20, and the second mounting base 112 provides an installation position for the second fixing mechanism 30, improving the convenience of installing the first fixing mechanism 20 and the second fixing mechanism 30.

[0039] In one embodiment, see Figure 4 and Figure 5 The first fixing mechanism 20 includes a support platform 21 and a first elastic element 22. The support platform 21 is used to support the flower basket 80, and the first elastic element 22 is disposed between the support platform 21 and the first mounting base 111. Optionally, the first elastic element 22 can be a compression spring, a rubber pad, or a gas spring, etc., and is not limited thereto. Under the action of the first elastic element 22, the support platform 21 can press against the flower basket 80, ensuring the reliability of the flower basket 80's fixation.

[0040] During operation, the lifting mechanism 10 drives the first fixing mechanism 20 and the second fixing mechanism 30 to move upward, thereby causing the flower basket 80 to move upward synchronously. When the picking and placing mechanism 90 contacts the lower end face 82 of the flower basket 80, the lifting mechanism 10 continues to drive the first fixing mechanism 20, the second fixing mechanism 30, and the flower basket 80 to move upward. The picking and placing mechanism 90 presses against the lower end face 82 of the flower basket 80, causing the support platform 21 to move away from the second fixing mechanism 30. During the movement of the support platform 21 away from the second fixing mechanism 30, the first elastic element 22 is gradually compressed. When the picking and placing mechanism 90 releases its pressure on the flower basket 80, the first elastic element 22 gradually extends and pushes the support platform 21 towards the second fixing mechanism 30, thereby restoring the support platform 21 to its original position. In addition, the first elastic element 22 forms a flexible connection between the first mounting base 111 and the support platform 21, which can effectively isolate or attenuate the vibration generated during the movement of the support platform 21.

[0041] In one embodiment, see Figure 4 and Figure 5 A base 51 is provided on the side of the support platform 21 away from the second fixing mechanism 30, and the base 51 is located between the first mounting base 111 and the support platform 21. One end of the first elastic member 22 is connected to the support platform 21, and the other end of the first elastic member 22 is connected to the base 51. In this way, the base 51 can provide support for the support platform 21 and the first elastic member 22.

[0042] In one embodiment, the detection mechanism 40 includes a first detection element. The first detection element is disposed on one of the support platform 21 and the base 51, and is used to detect the movement range of the first fixing mechanism 20. By providing the first detection element, the first detection element can detect the movement range of the first fixing mechanism 20. When the movement range of the first fixing mechanism 20 exceeds a predetermined value, the lifting mechanism 10 is controlled to stop operating, thus protecting the film loading / unloading mechanism 90 and preventing damage to it.

[0043] In one embodiment, see Figure 5 The first detection component is a pressure sensor 41. The pressure sensor 41 is located on the base 51, and the end of the first elastic member 22 facing away from the support platform 21 is connected to the pressure sensor 41.

[0044] Of course, in other embodiments, the pressure sensor 41 is disposed on the support platform 21, and the end of the first elastic member 22 facing away from the base 51 is connected to the pressure sensor 41.

[0045] During operation, the lifting mechanism 10 drives the first fixing mechanism 20 and the second fixing mechanism 30 to move upward, thereby causing the flower basket 80 to move upward synchronously. When the picking and placing mechanism 90 contacts the lower end face 82 of the flower basket 80, the lifting mechanism 10 continues to drive the first fixing mechanism 20, the second fixing mechanism 30, and the flower basket 80 to move upward. The picking and placing mechanism 90 then presses against the lower end face 82 of the flower basket 80, causing the support platform 21 to move away from the second fixing mechanism 30. During the movement of the support platform 21 away from the second fixing mechanism 30, the first elastic element 22 is gradually compressed and the force is transmitted to the pressure sensor 41, which measures the pressure value. When the pressure value is greater than or equal to a predetermined value, the lifting mechanism 10 is controlled to stop operating.

[0046] It should be noted that, according to Hooke's Law, the range of movement of the first fixed mechanism 20 in the first direction can be obtained from the external force (pressure value measured by pressure sensor 41) on the first elastic element 22 and the stiffness coefficient of the first elastic element 22.

[0047] In another embodiment, the first detection element is a proximity sensor. The proximity sensor is located on either the support platform 21 or the base 51. Specifically, the proximity sensor is located on the side of the support platform 21 facing the base 51, or the proximity sensor is located on the side of the base 51 facing the support platform 21. During operation, the pick-and-place mechanism 90 presses down against the lower end face 82 of the flower basket 80, the support platform 21 moves downward, and the distance between the support platform 21 and the base 51 gradually decreases. When the distance between the support platform 21 and the base 51 decreases to a set value, the proximity sensor is triggered and outputs a detection signal, the lifting mechanism 10 stops operating, thereby protecting the pick-and-place mechanism 90.

[0048] It should be noted that limit switches can also be used to replace proximity sensors.

[0049] In one embodiment, see Figure 5 One of the base 51 and the support platform 21 is provided with a protrusion 511, and the other of the base 51 and the support platform 21 is provided with a first guide sleeve 211. The first guide sleeve 211 is fitted onto the protrusion 511 and can move relative to the protrusion 511 in a first direction. In this way, with the cooperation of the protrusion 511 and the first guide sleeve 211, the movement direction of the support platform 21 can be effectively restricted, preventing the support platform 21 from deviating or shaking, ensuring the smooth movement of the support platform 21, thereby improving the reliability of fixing the flower basket 80 and the reliability of detection.

[0050] Further, see Figure 5The first detection element and the first elastic element 22 are both located inside the first guide sleeve 211. The first guide sleeve 211 can effectively resist external loads or impacts, prevent damage to the first detection element and the first elastic element 22, and improve the reliability and safety of the overall structure.

[0051] In one embodiment, see Figure 5 The flower basket lifting device also includes a first driving component 50. The first driving component 50 is mounted on the mounting frame 11 and drivenly connected to the base 51. The first driving component 50 drives the base 51 to move along a first direction. Optionally, the first driving component 50 is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, etc. When the flower basket 80 is conveyed to the support platform 21, the first driving component 50 drives the base 51 to move upward, thereby causing the flower basket 80 to move upward, so that the first fixing mechanism 20 and the second fixing mechanism 30 cooperate to clamp the flower basket 80.

[0052] In one embodiment, see Figure 2 The flower basket lifting device also includes a conveying mechanism 60. The conveying mechanism 60 is located on the mounting frame 11 and is used to transport the flower basket 80 to the support platform 21. In this way, under the action of the conveying mechanism 60, the flower basket 80 can be automatically transported to the support platform 21, reducing manual handling and improving the automation level of the production process.

[0053] Further, see Figure 2 The conveying mechanism 60 includes a first conveying module 61 and a second conveying module 62. The first conveying module 61 and the second conveying module 62 are respectively located on opposite sides of the support platform 21. Optionally, both the first conveying module 61 and the second conveying module 62 are pulley modules. In this way, the flower basket 80 is simultaneously supported and conveyed by the first conveying module 61 and the second conveying module 62 on both sides, resulting in even force distribution and avoiding skewing or shaking caused by unilateral conveying. This ensures that the flower basket 80 can be accurately and smoothly conveyed to the support platform 21, while reducing structural deformation or damage caused by excessive force on one side. Furthermore, it can improve the overall load-bearing capacity of the conveying mechanism 60.

[0054] In one embodiment, see Figure 2 The flower basket lifting device also includes a stop assembly 70. The stop assembly 70 is disposed on the mounting frame 11 and located in front of the support platform 21 along the conveying direction of the flower basket 80. In this configuration, the stop assembly 70 can stop the flower basket 80, so that the flower basket 80 stops on the support platform 21.

[0055] Further, see Figure 2The stop assembly 70 includes a power component 71 and a stop component 72. The power component 71 is driven to move the stop component 72 up and down in a first direction. When the conveying mechanism 60 conveys the flower basket 80, the power component 71 drives the stop component 72 to move upward, so that the top of the stop component 72 is higher than the support platform 21. In this way, the stop component 72 can stop the flower basket 80 and ensure that the flower basket 80 stays on the support platform 21. After the leaf picking and placing operation is completed, the power component 71 drives the stop component 72 to move downward, so that the top of the stop component 72 is lower than the support platform 21. In this way, the conveying mechanism 60 can continue to convey the flower basket 80 forward.

[0056] In one embodiment, see Figure 4 and Figure 6 The second fixing mechanism 30 includes a second driving member 31 and a pressing member 32. The second driving member 31 is driven to the pressing member 32, and the second driving member 31 is used to drive the pressing member 32 to move towards or away from the first fixing mechanism 20. Optionally, the second driving member 31 can be a cylinder, electric cylinder, hydraulic cylinder, etc., and is not limited thereto.

[0057] During operation, the flower basket 80 is placed on the support platform 21. To secure the flower basket 80, the second driving member 31 drives the pressing member 32 to move closer to the first fixing mechanism 20, causing the pressing member 32 to press against the upper end face 81 of the flower basket 80, thus securing the flower basket 80. To remove the flower basket 80, the second driving member 31 drives the pressing member 32 to move away from the first fixing mechanism 20, causing the pressing member 32 to separate from the flower basket 80, allowing the flower basket 80 to be removed from the support platform 21.

[0058] In one embodiment, see Figure 6 The pressing member 32 has a conical top. The conical top has a large end face and a small end face. The large end face connects to the second driving member 31, and the small end face is used to press against the upper end face 81 of the flower basket 80. Because the large end face of the conical top is connected to the second driving member 31, the force-bearing area is large, which can effectively disperse stress and avoid local deformation caused by stress concentration. Because the contact area between the small end face of the conical top and the flower basket 80 is small, the contact pressure is large, which can effectively prevent the flower basket 80 from loosening.

[0059] In one embodiment, see Figure 6 The second fixing mechanism 30 also includes a second elastic element 33. The second elastic element 33 is disposed between the second driving member 31 and the second mounting base 112, with one end connected to the second driving member 31 and the other end connected to the second mounting base 112. Optionally, the second elastic element 33 can be a compression spring, a rubber pad, or a gas spring, etc., and is not limited thereto. Thus, the second elastic element 33 can maintain a certain preload, allowing the second fixing mechanism 30 to press the flower basket 80 against the support platform 21, thereby fixing the flower basket 80.

[0060] During operation, the lifting mechanism 10 drives the first fixing mechanism 20 and the second fixing mechanism 30 to move downwards, thereby causing the flower basket 80 to move downwards synchronously. When the picking and placing mechanism 90 contacts the upper end face 81 of the flower basket 80, the lifting mechanism 10 continues to drive the first fixing mechanism 20, the second fixing mechanism 30, and the flower basket 80 to move downwards. The picking and placing mechanism 90 then presses against the upper end face 81 of the flower basket 80, causing the second driving member 31 to move away from the first fixing mechanism 20. During the movement of the second fixing mechanism 30 away from the first fixing mechanism 20, the second elastic member 33 gradually compresses. When the picking and placing mechanism 90 removes the pressure applied to the flower basket 80, the second elastic member 33 gradually recovers its elongation, pushing the second driving member 31 towards the first fixing mechanism 20, thus resetting the second driving member 31. Furthermore, the second elastic member 33 forms a flexible connection between the second driving member 31 and the second mounting base 112, effectively isolating or attenuating the vibration generated during the movement of the second driving member 31.

[0061] In one embodiment, the detection mechanism 40 further includes a second detection element disposed on one of the second drive member 31 and the second mounting base 112. The second detection element is used to detect the movement range of the second fixing mechanism 30. Specifically, the second detection element is disposed on the side of the second drive member 31 facing the second mounting base 112, or the second detection element is disposed on the side of the second mounting base 112 facing the second drive member 31. By providing the second detection element, the second detection element can detect the movement range of the second fixing mechanism 30. When the movement range of the second fixing mechanism 30 exceeds a predetermined value, the lifting mechanism 10 stops operating, thereby protecting the film pick-and-place mechanism 90 and preventing damage to the film pick-and-place mechanism 90.

[0062] In one embodiment, see Figure 6 The second detection element is a proximity sensor 42. The proximity sensor 42 is disposed in one of the second drive member 31 and the second mounting base 112. Specifically, the proximity sensor 42 is disposed on the side of the second drive member 31 facing the second mounting base 112, or the proximity sensor 42 is disposed on the side of the second mounting base 112 facing the second drive member 31.

[0063] During operation, the picking and placing mechanism 90 presses upward against the upper end face 81 of the flower basket 80, and the second driving member 31 moves upward, gradually reducing the distance between the second driving member 31 and the second mounting base 112. When the distance between the second driving member 31 and the second mounting base 112 decreases to a set value, the proximity sensor 42 is triggered and outputs a detection signal, and the lifting mechanism 10 stops operating, thereby protecting the picking and placing mechanism 90.

[0064] It should be noted that a limit switch can also be used to replace the proximity sensor 42.

[0065] In another embodiment, the second detection element is a pressure sensor. The pressure sensor is disposed on the side of the second mounting base 112 facing the second driving member 31, and the end of the second elastic member 33 facing away from the second driving member 31 is connected to the pressure sensor; or, the pressure sensor is disposed on the side of the second driving member 31 facing the second mounting base 112, and the end of the second elastic member 33 facing away from the second mounting base 112 is connected to the pressure sensor.

[0066] The picking and placing mechanism 90 presses upward against the upper end face 81 of the flower basket 80, the second driving member 31 moves upward, the second elastic member 33 is gradually compressed, and the second elastic member 33 transmits the force to the pressure sensor, which measures the pressure value it receives. When the pressure value is greater than or equal to a predetermined value, the lifting mechanism 10 stops operating.

[0067] It should be noted that, according to Hooke's Law, the range of movement of the second fixing mechanism 30 in the first direction can be obtained from the external force (pressure value measured by the pressure sensor) on the second elastic element 33 and the stiffness coefficient of the second elastic element 33.

[0068] In one embodiment, see Figure 6 A second guide sleeve 1121 is provided on the side of the second mounting base 112 facing the second driving member 31. The second driving member 31 is disposed within the second guide sleeve 1121 and can move along the first direction. Thus, the second guide sleeve 1121 provides precise guidance and support for the second driving member 31, effectively limiting the direction of movement of the second driving member 31, preventing the second driving member 31 from deviating or wobbling, and ensuring that the second driving member 31 moves smoothly along the first direction, thereby improving the reliability of the flower basket 80 fixing and the reliability of detection. Furthermore, the second guide sleeve 1121 can effectively resist external loads or impacts, preventing the second driving member 31 from deforming or being damaged, improving the reliability and safety of the overall structure.

[0069] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0070] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0071] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0072] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0073] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
