Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a transfer device and a solar cell production system. Background Technology

[0002] In the production of solar cells, such as the cell coating process, a gantry-style cell loading and unloading mechanism and a flipping mechanism are typically used to flip the cells. Specifically, after a full basket is transported to a preset position, the cell loading mechanism removes the cells from the basket and transfers them to a conveyor mechanism. The conveyor mechanism then transports the cells to a lifting platform area, where the lifting platform lifts the cells. The gantry's suction cups then move laterally to the lifting platform to pick up the cells and transfer them to a carrier plate. After coating is completed, the carrier plate is moved from the coating chamber to the cell loading position. The gantry transfers the cells from the carrier plate to the conveyor mechanism, which then transports them to a flipping mechanism. The flipping mechanism flips the cells, and finally, the gantry transfers the cells from the flipping mechanism back to the carrier plate. However, this method suffers from low production efficiency and low yield. Utility Model Content

[0003] Therefore, it is necessary to provide a flipping and loading device and a solar cell production system to ensure the processing quality of the cells while improving production efficiency.

[0004] In a first aspect, this application provides a transfer device, comprising:

[0005] The support mechanism is used to support the battery cells;

[0006] A flipping mechanism is connected to the supporting mechanism, and the flipping mechanism is used to drive the supporting mechanism to flip by a preset angle.

[0007] A lifting mechanism is provided, which is connected to the supporting mechanism and is used to drive the supporting mechanism to move up and down.

[0008] A lateral movement mechanism, connected to the lifting mechanism, is used to drive the supporting mechanism to move above a preset position; and

[0009] A fixing mechanism is provided on the supporting mechanism, and the fixing mechanism has a fixed state for fixing the battery cell to the supporting mechanism and a released state for releasing the battery cell to the preset position.

[0010] In one embodiment, the carrying mechanism includes a conveying assembly, which includes drive wheels and a transmission member for carrying the battery cells. The drive wheels are provided in at least two configurations and are spaced apart in a direction perpendicular to the lateral movement direction of the lateral movement mechanism. The transmission member is drively connected to all the drive wheels.

[0011] In one embodiment, the carrying mechanism has multiple fixed positions, all of which are spaced apart along the conveying direction of the conveying assembly; the overturning and transferring device further includes a controller and a detection mechanism, the controller being communicatively connected to the lifting mechanism, the fixing mechanism, and the detection mechanism; when the detection mechanism detects that all the fixed positions have the battery cell, the controller controls the lifting mechanism to rise and controls the fixing mechanism to fix the battery cell.

[0012] In one embodiment, the conveying assembly includes two transmission members arranged side by side and spaced apart along a direction parallel to the transverse direction; the detection mechanism includes multiple detection elements, all of which are disposed between the two transmission members, are spaced apart along the conveying direction, and correspond one-to-one with all the fixed positions.

[0013] In one embodiment, the carrying mechanism further includes a first limiting member, and there are multiple first limiting members. All the first limiting members are provided on the transmission member. All the first limiting members are spaced apart along the conveying direction. Two adjacent first limiting members cooperate to limit the two ends of the battery cell along the conveying direction.

[0014] In one embodiment, the first limiting member includes a first bearing portion, a second bearing portion, and a limiting structure. The first bearing portion and the second bearing portion are spaced apart along the conveying direction. The first bearing portion is used to carry one of the adjacent battery cells, and the second bearing portion is used to carry the other adjacent battery cell. The limiting structure is disposed between the first bearing portion and the second bearing portion and is used to limit the two adjacent battery cells. The limiting structure includes a first limiting portion and a second limiting portion. In the conveying direction, the first limiting portion is inclined from the first bearing portion in a direction away from the transmission member. In the direction opposite to the conveying direction, the second limiting portion is inclined from the second bearing portion in a direction away from the transmission member.

[0015] In one embodiment, the supporting mechanism further includes a second limiting member and a third limiting member, with at least one second limiting member and at least one third limiting member provided between two adjacent first limiting members. The second limiting member and the third limiting member cooperate to limit the two ends of the battery cell in a direction parallel to the lateral movement direction.

[0016] In one embodiment, the second limiting member includes a third bearing portion and a third limiting portion. The third bearing portion is connected to the transmission member and is used to support the battery cell. The third limiting portion is connected to the third bearing portion and is inclined from the third bearing portion in a direction away from the third limiting member toward a direction away from the transmission member.

[0017] And / or, the third limiting member includes a fourth bearing portion and a fourth limiting portion, the fourth bearing portion being connected to the transmission member, the fourth bearing portion being used to support the battery cell, and the fourth limiting portion being connected to the fourth bearing portion and tilting from the fourth bearing portion in a direction away from the second limiting member toward a direction away from the transmission member.

[0018] In one embodiment, the preset angle is 180°.

[0019] Secondly, this application provides a solar cell production system, including a carrier plate and the aforementioned flipping and transferring device. The carrier plate is disposed at the preset position, and the flipping and transferring device is used to flip the solar cell by a preset angle and transfer the flipped solar cell to the carrier plate.

[0020] In the aforementioned flipping and loading device and solar cell production system, the solar cells are placed on the carrying mechanism during operation. Then, a lifting mechanism drives the carrying mechanism to rise, leaving sufficient height space for flipping, while a fixing mechanism secures the solar cells, keeping them stationary relative to the carrying mechanism. Once the carrying mechanism reaches a first preset height, a flipping mechanism drives it to flip by a preset angle, causing the solar cells to flip as well. Then, a lateral movement mechanism drives the carrying mechanism to move. When the carrying mechanism moves above a preset position, the lifting mechanism drives it to descend to a second preset height, and the fixing mechanism releases the solar cells at the preset position, preventing them from breaking due to a fall. In this way, the flipping and loading device can replace the gantry for loading and unloading, improving suction cup marks and ensuring the processing quality of the solar cells. It also optimizes the unloading gantry and the large fan flipping mechanism, eliminating the need for real-time monitoring of the gantry torque and replacement of suction cups, thus reducing costs and improving processing efficiency.

Detailed Implementation

[0029] 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.

[0030] See Figure 1 , Figure 3 and Figure 4 This application provides a flipping and transferring device 10, which includes a bearing mechanism 12, a flipping mechanism 13, a lifting mechanism 14, a lateral movement mechanism 15, and a fixing mechanism 16.

[0031] See Figure 1 and Figure 4 The support mechanism 12 is used to support the battery cells.

[0032] See Figure 1 and Figure 2The flipping mechanism 13 is connected to the carrying mechanism 12, and the flipping mechanism 13 is used to drive the carrying mechanism 12 to flip by a preset angle. Optionally, the preset angle is 180°. During operation, the battery cell is placed on the carrying mechanism 12 with the front side facing up and the back side facing down. The flipping mechanism 13 drives the carrying mechanism 12 to flip 180°, so that the back side of the battery cell faces up and the front side faces down.

[0033] Optionally, the flipping mechanism 13 includes a servo motor. The output shaft of the servo motor is directly connected to the frame 126 of the bearing mechanism 12, or the output shaft of the servo motor is indirectly connected to the frame 126 of the bearing mechanism 12 via a connecting shaft.

[0034] See Figure 2 The lifting mechanism 14 is connected to the bearing mechanism 12, and the lifting mechanism 14 is used to drive the bearing mechanism 12 to lift.

[0035] Optionally, the lifting mechanism 14 may be a linear module, a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, etc., and is not limited thereto.

[0036] See Figure 1 and Figure 3 The lateral movement mechanism 15 is connected to the lifting mechanism 14. The lateral movement mechanism 15 is used to drive the bearing mechanism 12 to move above the preset position 20.

[0037] Optionally, the traversing mechanism 15 is a linear module, which can be a screw-driven linear module, a timing belt-driven linear module, or a rack and pinion-driven linear module. The linear module includes a sliding member, which is connected to the lifting mechanism 14.

[0038] See Figure 1 and Figure 4 The fixing mechanism 16 is provided on the supporting mechanism 12. The fixing mechanism 16 has a fixed state in which the battery cell is fixed to the supporting mechanism 12 and a released state in which the battery cell is released to a preset position 20.

[0039] During operation, the battery cells are placed on the carrying mechanism 12. Then, the lifting mechanism 14 drives the carrying mechanism 12 to rise, leaving a certain height space for the carrying mechanism 12 to rotate. At the same time, the fixing mechanism 16 fixes the battery cells, making them stationary relative to the carrying mechanism 12. When the carrying mechanism 12 rises to the first preset height, the rotating mechanism 13 drives the carrying mechanism 12 to rotate by a preset angle, causing the battery cells to rotate by the preset angle. Then, the traversing mechanism 15 drives the carrying mechanism 12 to move. When the carrying mechanism 12 moves above the preset position 20, the lifting mechanism 14 drives the carrying mechanism 12 to descend to the second preset height, and the fixing mechanism 16 releases the battery cells at the preset position 20, preventing the battery cells from breaking due to falling. In this way, the rotating and loading device 10 can replace the gantry for picking up and placing cells, improve the suction cup marks, ensure the processing quality of the battery cells, and optimize the unloading gantry and the large fan rotating mechanism 13. It eliminates the need for real-time monitoring of the gantry torque value and replacement of suction cups, which helps to reduce costs and improve processing efficiency.

[0040] In one embodiment, see Figure 3 and Figure 4 The carrying mechanism 12 includes a conveying assembly 121 and a frame 126. The conveying assembly 121 is disposed on the frame 126 and is used to convey battery cells. Optionally, the conveying direction of the conveying assembly 121 is perpendicular to the lateral movement direction of the lateral movement mechanism 15. S1 represents the lateral movement direction of the lateral movement mechanism 15, and S2 represents the conveying direction of the conveying assembly 121.

[0041] Further, see Figure 4 The conveying assembly 121 includes a drive wheel 1211 and a drive member 1212. There are at least two drive wheels 1211. All drive wheels 1211 are spaced apart in a direction perpendicular to the transverse direction. The drive member 1212 is connected to all drive wheels 1211 in a transmission connection.

[0042] Optionally, the conveying component 121 may be a pulley module or a sprocket module, etc., and is not limited thereto.

[0043] During operation, the transmission wheel 1211 rotates, driving the transmission component 1212 to move. The battery cells are placed on the transmission component 1212, which then moves the battery cells, thus transporting them.

[0044] In one embodiment, see Figure 3 and Figure 4 The carrying mechanism 12 includes at least two conveying assemblies 121, all of which are arranged side-by-side and spaced apart in a direction parallel to the lateral movement direction. It is understood that a frame 126 is provided with at least two conveying assemblies 121, thereby improving the efficiency of the transfer and loading process.

[0045] In this embodiment, the carrying mechanism 12 includes two conveying components 121, which are arranged side by side and spaced apart along a direction parallel to the transverse direction.

[0046] In one embodiment, see Figure 4 The carrying mechanism 12 has a fixed position 1251. There are multiple fixed positions 1251, and all fixed positions 1251 are spaced apart along the conveying direction.

[0047] Furthermore, the overturning and transfer device 10 also includes a controller and a detection mechanism 17. The controller is communicatively connected to the detection mechanism 17, the lifting mechanism 14, and the fixing mechanism 16. When the detection mechanism 17 detects that all the fixing positions 1251 have battery cells, the controller controls the lifting mechanism 14 to drive the carrying mechanism 12 to rise and controls the fixing mechanism 16 to fix the battery cells.

[0048] During operation, multiple battery cells are placed one by one on the transmission component 1212, which transports the battery cells forward under the drive of the transmission wheel 1211. When the detection mechanism 17 detects that there are battery cells in all the fixing positions 1251, it feeds the signal back to the controller. The controller controls the lifting mechanism 14 to drive the carrying mechanism 12 to rise, and at the same time controls the fixing mechanism 16 to fix the battery cells.

[0049] In one embodiment, see Figure 4 and Figure 6 The conveying assembly 121 includes two transmission members 1212, which are arranged side by side and spaced apart along a direction parallel to the transverse direction.

[0050] Further, see Figure 4 The detection mechanism 17 includes multiple detection elements 171. All detection elements 171 are located between two transmission components 1212, and each detection element 171 corresponds one-to-one with each fixed position 1251. During operation, when all detection elements 171 simultaneously detect a battery cell, it indicates that a battery cell is present at each fixed position 1251. Then, the controller controls the lifting mechanism 14 to drive the carrying mechanism 12 upwards, while simultaneously controlling the fixing mechanism 16 to fix the battery cell. This improves detection accuracy and avoids misjudgments.

[0051] Optionally, the detection element 171 is an inductive sensor. Of course, in other embodiments, the detection element 171 may also be an image sensor, and is not limited thereto.

[0052] It should be noted that the detection component 171 can not only detect whether all the fixing positions 1251 have battery cells, but also detect whether the battery cells are fragments.

[0053] In one embodiment, the transmission member 1212 has a first transmission side and a second transmission side opposite to each other.

[0054] Further, see Figure 4 The supporting mechanism 12 also includes a carrying rack 125. The carrying rack 125 is located between the first transmission side and the second transmission side and extends in a direction perpendicular to the transverse direction. All the detection elements 171 are located on the carrying rack 125 and are spaced apart along the extending direction of the carrying rack 125.

[0055] Further, see Figure 4 Both drive wheels 1211 are mounted on the rack 125. Optionally, the two drive wheels 1211 are mounted at opposite ends of the rack 125 in its extension direction. In this way, the rack 125 provides mounting positions for the detection component 171 and the drive wheels 1211, improving the ease of installation for both. Furthermore, since the rack 125 is located between the first and second drive sides, interference between the rack 125 and the drive component 1212 can be avoided.

[0056] In one embodiment, see Figure 4 and Figure 5 The carrying mechanism 12 also includes a first limiting member 122. Multiple first limiting members 122 are provided, all of which are located on the transmission member 1212 and are spaced apart along the conveying direction. In the conveying direction, adjacent first limiting members 122 cooperate to limit the two ends of the battery cell along the conveying direction.

[0057] Optionally, in the conveying direction, the spacing between two adjacent first limiting members 122 is adapted to the length of the long side of the battery cell. In this way, the two adjacent first limiting members 122 are used to limit the short side of the battery cell.

[0058] During operation, a single battery cell is placed between two adjacent first limiting members 122. The two adjacent first limiting members 122 can limit the two ends of the single battery cell along the conveying direction. This can prevent the front and rear battery cells from overlapping in the conveying direction, thereby preventing the battery cell from breaking due to overlapping and reducing the breakage rate of the battery cell.

[0059] In this embodiment, see Figure 4 Both transmission components 1212 are provided with multiple first limiting components 122, and the first limiting components 122 of the two transmission components 1212 are set in a one-to-one correspondence.

[0060] In one embodiment, see Figure 5The first limiting member 122 includes a first supporting part 1221, a second supporting part 1222, and a limiting structure. The first supporting part 1221 and the second supporting part 1222 are spaced apart along the conveying direction. The first supporting part 1221 is used to support one of the adjacent battery cells, and the second supporting part 1222 is used to support the other adjacent battery cell. The limiting structure is located between the first supporting part 1221 and the second supporting part 1222, and the limiting structure is used to separate two adjacent battery cells. In this way, one first limiting member 122 can support and limit two adjacent battery cells, which can reduce the number of first limiting members 122 and save costs.

[0061] It is understandable that the first support portion 1221 and the second support portion 1222 are arranged horizontally.

[0062] Further, see Figure 5 The limiting structure includes a first limiting part 1223 and a second limiting part 1224. In the conveying direction, the first limiting part 1223 is inclined from the first bearing part 1221 in a direction away from the transmission member 1212. In the opposite direction to the conveying direction, the second limiting part 1224 is inclined from the second bearing part 1222 in a direction away from the transmission member 1212. It can be understood that the first limiting part 1223 and the second limiting part 1224 are arranged at an angle. In the conveying direction, the distance between two adjacent first limiting parts 1223 and second limiting parts 1224 gradually increases from bottom to top, which facilitates the placement of the battery cell between two adjacent first limiting members 122.

[0063] In one embodiment, participants Figure 5 The supporting mechanism 12 also includes a second limiting member 123 and a third limiting member 124. At least one second limiting member 123 and at least one third limiting member 124 are provided between two adjacent first limiting members 122. The second limiting member 123 and the third limiting member 124 cooperate to limit the two ends of the battery cell in a direction parallel to the lateral movement direction.

[0064] Optionally, in a direction parallel to the lateral movement direction, the distance between the second limiting member 123 and the third limiting member 124 is adapted to the length of the short side of the battery cell. Thus, the second limiting member 123 and the third limiting member 124 cooperate to limit the long side of the battery cell, preventing adjacent battery cells from overlapping in a direction parallel to the lateral movement direction, thereby preventing breakage due to overlapping and reducing the breakage rate of the battery cells.

[0065] Optionally, see Figure 5 The second limiting member 123 can be set to correspond with the third limiting member 124.

[0066] Of course, in other embodiments, the second limiting member 123 may also be set separately from the third limiting member 124.

[0067] In one embodiment, see Figure 5 The second limiting member 123 includes a third bearing portion 1231 and a third limiting portion 1232. The third bearing portion 1231 is disposed on the transmission member 1212, and the third limiting portion 1232 is disposed on the third bearing portion 1231. Optionally, the third bearing portion 1231 is horizontally disposed.

[0068] See Figure 5 The third limiting member 124 includes a fourth bearing portion 1241 and a fourth limiting portion 1242. The fourth bearing portion 1241 is disposed on the transmission member 1212, and the fourth limiting portion 1242 is disposed on the fourth bearing portion 1241. Optionally, the fourth bearing portion 1241 is horizontally disposed.

[0069] Thus, the third support part 1231 and the fourth support part 1241 can support both sides of the battery cell, the third limiting part 1232 can limit one side of the battery cell, and the fourth limiting part 1242 can limit the other side of the battery cell.

[0070] In one embodiment, see Figure 5 The third limiting portion 1232 is located at one end of the third bearing portion 1231 opposite to the third limiting member 124, and is inclined from the third bearing portion 1231 in a direction opposite to the third limiting member 124 towards the direction opposite to the transmission member 1212. And / or, the fourth limiting portion 1242 is located at one end of the fourth bearing portion 1241 opposite to the second limiting member 123, and is inclined from the fourth bearing portion 1241 in a direction opposite to the second limiting member 123 towards the direction opposite to the transmission member 1212. Thus, the distance between two adjacent third limiting portions 1232 and fourth limiting portions 1242 gradually increases from bottom to top, facilitating the placement of the battery cell between the second limiting member 123 and the third limiting member 124.

[0071] In one embodiment, see Figure 6 The fixing mechanism 16 includes a fixing part 161. The fixing part 161 is provided on the frame 126 of the bearing mechanism 12 and is correspondingly provided with the fixing position 1251.

[0072] Further, see Figure 6 The fixing part 161 is provided with an adsorption pore 1611, and each fixing position 1251 is provided with at least one adsorption pore 1611.

[0073] Furthermore, the fixing mechanism 16 also includes a vacuum generator and an air pipe. The vacuum generator is connected to the adsorption air hole 1611 through the air pipe, and the vacuum generator is communicatively connected to the controller.

[0074] During operation, when the detection mechanism 17 detects that all fixing positions 1251 have solar cells, the controller activates the vacuum generator. The vacuum generator uses air pipes and suction vents 1611 to remove air between the suction vents 1611 and the solar cells to create a vacuum. Because the air pressure between the suction vents 1611 and the solar cells is lower than the atmospheric pressure outside the solar cells, the solar cells are thus adsorbed and fixed to the support mechanism 12 under external pressure.

[0075] Of course, in other embodiments, the fixing mechanism 16 may also be a clamping mechanism.

[0076] In one embodiment, see Figure 5 The overturning and loading device 10 also includes a cell-retrieving mechanism 18. The cell-retrieving mechanism 18 is used to remove the battery cells from the basket and place them on the carrying mechanism 12.

[0077] Optionally, the cell-retrieving mechanism 18 can be a cell-retrieving device. The cell-retrieving device uses the principle of vacuum adsorption to extract the battery cells from the basket.

[0078] See Figure 1 An embodiment of this application provides a solar cell production system, including a carrier plate and a flipping and transferring device 10 as described above. The carrier plate is located at a preset position 20, and the flipping and transferring device 10 is used to flip the solar cells and transfer the flipped solar cells to the carrier plate.

[0079] In the aforementioned solar cell production system, during operation, the solar cells are placed on the carrying mechanism 12. Then, the lifting mechanism 14 drives the carrying mechanism 12 to rise, reserving a certain height space for the carrying mechanism 12 to rotate. Simultaneously, the fixing mechanism 16 secures the solar cells, keeping them stationary relative to the carrying mechanism 12. When the carrying mechanism 12 rises to a first preset height, the rotating mechanism 13 drives the carrying mechanism 12 to rotate by a preset angle, causing the solar cells to rotate at the preset angle. Then, the traversing mechanism 15 drives the carrying mechanism 12 to move. When the carrying mechanism 12 moves above a preset position 20, the lifting mechanism 14 drives the carrying mechanism 12 to descend to a second preset height, and the fixing mechanism 16 releases the solar cells at the preset position 20, preventing them from breaking due to falling. Thus, the rotating and loading device 10 can replace the gantry for loading and unloading, improving suction cup marks and ensuring the processing quality of the solar cells. It also optimizes the loading gantry and the large fan rotating mechanism 13, eliminating the need for real-time monitoring of the gantry torque value and replacement of suction cups, thereby reducing costs and improving processing efficiency.

[0080] In solar cell production, the transfer device 10 can be applied to the chemical vapor deposition process.

[0081] Specifically, the cell-retrieving mechanism 18 extracts the battery cells from the basket and places them on the transmission component 1212, which then transports the battery cells forward. Once the detection mechanism 17 detects that all fixing positions 1251 have battery cells, the lifting mechanism 14 drives the carrying mechanism 12 to rise, while the fixing mechanism 16 secures the battery cells. When the carrying mechanism 12 rises to a first preset height, the flipping mechanism 13 drives it to flip 180°. Then, the lateral movement mechanism 15 drives the carrying mechanism 12 to move. When the lateral movement mechanism 15 moves above the carrier plate, the lifting mechanism 14 drives the carrying mechanism 12 to descend to a second preset height, and then the fixing mechanism 16 releases the battery cells onto the carrier plate.

[0082] Of course, in solar cell production, the flipping and transfer device 10 can also be used in the double-sided coating process to replace the flipping machine.

[0083] Specifically, the unloading gantry picks up the battery cells from the coated carrier plate and places them on the transmission component 1212, which then transports the battery cells forward. When the detection mechanism 17 detects that all the fixing positions 1251 have battery cells, the lifting mechanism 14 drives the carrying mechanism 12 to rise, while the fixing mechanism 16 fixes the battery cells. When the carrying mechanism 12 rises to the first preset height, the flipping mechanism 13 drives the carrying mechanism 12 to flip 180°. Then, the traversing mechanism 15 drives the carrying mechanism 12 to move. When the traversing mechanism 15 moves above the carrier plate, the lifting mechanism 14 drives the carrying mechanism 12 to descend to the second preset height, and then the fixing mechanism 16 releases the battery cells onto the carrier plate.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.
