Description

Technical Field

[0001] This utility model relates to the field of grease application technology, and in particular to an automatic grease application device. Background Technology

[0002] The air conditioner's air deflector is a crucial component inside the air conditioner, primarily used to regulate the direction of airflow for uniform and precise temperature distribution within the room. An air conditioner air deflector typically consists of a deflector body and a connecting shaft. The connecting shaft connects to a drive structure, enabling the drive structure to rotate the deflector. During air conditioner manufacturing, applying grease to the connecting shaft of the air deflector is a critical step, mainly to reduce abnormal noise and rattles generated by the deflector's continuous rotation during use. Traditional grease application relies on manual operation, where operators apply a layer of grease to the surface of the connecting shaft to reduce operating noise. This experience-based grease application method has significant drawbacks: the traditional method relies on the operator's experience to judge the amount and effect of grease, leading to drastic fluctuations in efficiency and quality, making it difficult to control. Prolonged operation can also cause eye fatigue, thus affecting operational accuracy.

[0003] Therefore, it is necessary to improve the existing manual method of applying grease to the connecting shaft in order to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, the purpose of this utility model is to provide an automatic grease application device that can automatically grease workpieces and detect the grease application status using a vision inspection system, thereby ensuring the grease application quality.

[0005] An automatic coating device includes a main body with a conveyor line disposed on the main body; a vision inspection system is disposed above the conveyor line and is oriented toward the conveyor line.

[0006] The main body is provided with a grease application station, which is located below the vision inspection system. The grease application station includes a fixture and a grease application structure. The grease application structure is located on one side of the fixture. The fixture is used to hold the workpiece to be greased, and the grease application structure includes a grease application nozzle for grease application to the workpiece.

[0007] This device uses a vision inspection system to analyze workpieces, accurately identify the grease application area and condition, and ensure precise grease application. Combined with the grease application structure and control system, it enables precise control of the grease spray volume and pressure, resulting in uniform grease thickness and preventing localized over- or under-grease application, thus significantly improving the lubrication effect on the workpiece.

[0008] Automated lubrication processes significantly reduce manual operations, resulting in a substantial increase in production speed compared to traditional manual lubrication methods. The stable operation of the conveyor line and the efficient collaboration between workstations enable continuous, uninterrupted production. Furthermore, the work rhythm can be flexibly adjusted according to production needs, effectively meeting the demands of large-scale production, reducing production costs, and enhancing the company's competitiveness in the market.

[0009] In a preferred embodiment of this invention, a grease supply system is also included. The grease supply system includes a grease storage tank, a pressure controller, and a grease supply device. The grease storage tank and the grease supply device are both mounted on the main body. The grease storage tank is connected to the input port of the grease supply device via a connecting pipe. The output port of the grease supply device is connected to the grease nozzle. The pressure controller is mounted on the connecting pipe.

[0010] Throughout the grease application process, the grease tank, pressure controller, and grease supply device of the grease supply system work together to ensure that the grease nozzle can continuously and stably output lubricating grease at the required pressure and flow rate, thereby ensuring the consistency and reliability of the grease quantity, meeting the grease application needs of different workpieces, and improving the overall performance and production efficiency of the equipment.

[0011] In a preferred embodiment of this invention, the visual inspection system includes a first guide rail, a first slider, and a vision lens. The first guide rail spans above the conveyor line, and a plurality of first sliders are disposed on the first guide rail. Each first slider is provided with a vision lens, and the vision lens is positioned facing the conveyor line.

[0012] Multiple vision lenses capture images of components from different angles, providing more comprehensive image information compared to a single lens and effectively avoiding blind spots caused by viewing angle issues. For components with complex shapes, it can more accurately identify the lubrication requirements of various surfaces and details, thereby significantly improving the accuracy and completeness of lubrication and reducing the incidence of product quality problems caused by poor lubrication.

[0013] In a preferred embodiment of this utility model, the clamp includes a bracket, a pneumatic gripper, and a rotation drive system. The bracket is disposed on one side of the conveyor line, and the pneumatic gripper is rotatably mounted on the bracket.

[0014] The rotation drive system is mounted on the bracket, and the rotation drive system drives the pneumatic gripper to rotate on the bracket.

[0015] In a preferred embodiment of this invention, the rotation drive system includes a drive motor, a turntable, and a transmission belt. The drive motor is fixed on the bracket, the turntable is rotatably mounted on the bracket, and one side of the turntable is fixedly connected to the pneumatic gripper via a connecting shaft. The transmission belt is connected between the output end of the drive motor and the turntable.

[0016] In a preferred embodiment of this invention, two clamps are provided, and the two clamps are positioned opposite each other on opposite sides of the conveyor line.

[0017] This application employs two opposing clamps that can simultaneously apply clamping force from both sides of the workpiece. Compared to a single clamp, this significantly enhances the workpiece's stability during grease application, effectively preventing uneven or misaligned grease application caused by workpiece movement. Simultaneously, the clamp's rotation drive system ensures the workpiece rotates at a uniform speed during grease application, guaranteeing that the grease nozzles can apply grease to the workpiece surface from all angles. This results in a more uniform and comprehensive grease application, improving the product's lubrication quality and extending the service life of the drive shaft.

[0018] In a preferred embodiment of this invention, two grease coating structures are provided, and the two grease coating structures are arranged opposite each other on opposite sides of the conveyor line.

[0019] In a preferred embodiment of this utility model, the grease coating structure further includes a second guide rail, a second slider, and a grease coating box. The second guide rail is disposed on one side of the conveyor line, and the length direction of the second guide rail is the same as the conveying direction of the conveyor line. The second slider is disposed on the second guide rail, and the grease coating box is fixed on the second slider.

[0020] The grease box is equipped with a toothed plate, a transmission gear, and a linear drive structure. The linear drive structure is fixed inside the grease box, and its output end is fixedly connected to the toothed plate. The transmission gear is rotatably disposed inside the grease box, and the toothed plate meshes with the transmission gear.

[0021] A transmission pipe is provided in the middle of the transmission gear, one end of which is exposed outside the grease box. The grease nozzle is provided on the transmission pipe, and the transmission pipe is connected to the grease supply system. The grease nozzle is also provided with a sensor, which is fixed on the transmission pipe. The sensor is an infrared sensor used to detect whether the air guide plate has reached below the grease nozzle.

[0022] The two opposing grease-applying structures allow for simultaneous grease application to the connecting shafts on both sides of the air guide plate. Compared to a single grease-applying structure, this significantly reduces grease application time and improves production efficiency. Furthermore, the precise transmission and adjustment mechanism within the grease-applying box ensures that the grease-applying nozzles accurately reach the desired grease application location and enables multi-angle grease spraying, ensuring that the grease is applied evenly and accurately to the connecting shafts of the air guide plate.

[0023] In a preferred embodiment of this invention, a recycling bin is provided below the transmission pipe, and the recycling bin is connected to the grease supply device.

[0024] The recycling bin is used to collect excess or spilled grease during the grease application process. Through a specially designed piping and pumping system (e.g., using corrosion-resistant hoses and equipped with a small gear pump for grease delivery), this collected grease can be returned to the grease supply unit for reuse. This avoids environmental pollution problems that may result from improper waste grease disposal, achieves grease recycling, and improves the environmental friendliness and economy of the entire grease application system.

[0025] The beneficial effects of this utility model are as follows:

[0026] This utility model provides an automatic grease coating device, which includes a main body with a conveyor line. A vision inspection system is positioned above the conveyor line, facing it. A grease coating station is located below the vision inspection system on the main body. The grease coating station includes a fixture and a grease coating structure, with the structure located on one side of the fixture. The fixture holds the workpiece to be greased, and the grease coating structure includes a grease nozzle for applying grease to the workpiece. During use, the conveyor line feeds the workpiece to the grease coating station. When the vision inspection system detects the workpiece's arrival at the station, it sends a signal to the control system. The control system then controls the fixture to hold the workpiece, and the grease coating structure begins operation, spraying lubricating grease onto designated areas of the workpiece surface using the grease nozzle. Throughout the grease coating process, the vision inspection system continuously monitors the coating process to ensure quality. This device automates the grease coating process, significantly reducing manual operation and greatly increasing production speed compared to traditional manual grease coating methods. Furthermore, the visual inspection system can accurately identify the application area and condition of the grease, ensuring the precision of the grease application. It can also control the grease application quality, ensuring quality and extending the service life of the workpiece. Attached Figure Description

Detailed Implementation

[0035] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0036] The production of air conditioner outdoor unit covers involves multiple processes, such as stamping, surface treatment, and accessory assembly. Between different production stages, the covers are typically suspended from hooks on a suspension chain, allowing for orderly movement between processes. This ensures the continuity and smoothness of the production process, avoids delays in transfer between stages, and improves overall production efficiency.

[0037] However, in the production and assembly of air conditioner outdoor unit covers, manual labor is typically used to move and hang the covers from the overhead conveyor belt. This process is time-consuming, extremely inefficient, and severely impacts production schedules. Furthermore, the prolonged handling and assembly work places a heavy burden on workers' physical health due to the high intensity of their labor. Moreover, during manual handling and assembly, uncontrollable damage often occurs due to variations in the degree of movement and assembly. This damage not only leads to a decline in product quality but also wastes resources, increasing production costs and the difficulty of quality control for the company.

[0038] Based on this, this application provides an automatic grease application device.

[0039] Example 1

[0040] See Figures 1-6 This embodiment provides an automatic grease application device, comprising:

[0041] The main body 2 is provided with a conveyor line 6; a vision inspection system 4 is provided above the conveyor line 6 and is positioned facing the conveyor line.

[0042] The main body 2 is provided with a grease application station, which is located below the vision inspection system 4. The grease application station includes a clamp 3 and a grease application structure 5. The grease application structure 5 is located on one side of the clamp 3. The clamp 3 is used to hold the workpiece to be greased, and the grease application structure 5 includes a grease application nozzle 51 for greasing the workpiece.

[0043] Specifically, the main body 2 serves as the basic structure of the device, providing installation locations for various equipment. In one embodiment, the main body 2 can be made of high-strength aluminum alloy to ensure the stability and durability of the overall structure.

[0044] The vision inspection system 4 is installed 30-50 cm above the conveyor line, using a high-resolution CCD camera with over 5 million pixels, paired with a professional optical lens and intelligent image processing software. Through precise calibration, its field of view can completely cover the workpieces on the conveyor line, ensuring image clarity and accuracy.

[0045] The clamp 3 at the grease application station is designed as a quick-change and adjustable mechanical gripper structure, tailored to the workpiece to be greased, to ensure stable clamping of the workpiece. For example, if the workpiece to be greased is an air guide plate, the clamp 3 must be able to stably clamp the air guide plate body 2.

[0046] During production, the device is started, and the workpiece to be coated (air guide plate) is placed at the beginning of the conveyor line. The conveyor line runs at a certain speed, transporting the workpiece to below the vision inspection system 4. The vision inspection system 4 is activated, scans and images the workpiece, and uses image recognition algorithms to quickly analyze the surface features, shape, and dimensions of the workpiece. This data is transmitted in real time to the central control system of the device.

[0047] When the workpiece arrives at the grease application station, the fixture 3, acting according to the instructions of the central control system, precisely clamps the workpiece, ensuring its stability during the grease application process. The grease application structure 5, under the control of the control system, adjusts the position and angle of the grease application nozzle 51 according to the type of workpiece and grease application requirements, spraying grease onto the workpiece. During the grease application process, the vision inspection system 4 continuously monitors the grease application. If uneven grease application or grease splattering is detected, feedback is sent to the control system, which then adjusts the grease application parameters or pauses the grease application operation for correction.

[0048] After the grease is applied, the fixture 3 releases the workpiece and transports it to the subsequent process or finished product area via the conveyor line, completing a full grease application process.

[0049] This device, through its vision inspection system 4, can analyze the workpiece, accurately identify the grease application area and condition, and ensure the precision of the grease application. Combined with the grease application structure 5 and the control system, it can achieve precise control of the grease spray volume and pressure, resulting in a uniform grease thickness and avoiding localized over- or under-grease application, thereby significantly improving the lubrication effect on the workpiece.

[0050] Automated lubrication processes significantly reduce manual operations, resulting in a substantial increase in production speed compared to traditional manual lubrication methods. The stable operation of the conveyor line and the efficient collaboration between workstations enable continuous, uninterrupted production. Furthermore, the work rhythm can be flexibly adjusted according to production needs, effectively meeting the demands of large-scale production, reducing production costs, and enhancing the company's competitiveness in the market.

[0051] More preferably, it also includes a grease supply system 1, which includes a grease storage tank 11, a pressure controller 12, and a grease supply device 13. Both the grease storage tank 11 and the grease supply device 13 are mounted on the main body 2. The grease storage tank 11 is connected to the input port of the grease supply device 13 via a connecting pipe, and the output port of the grease supply device 13 is connected to the grease nozzle 51. The pressure controller 12 is mounted on the connecting pipe. The pressure controller 12 can control...

[0052] The grease storage tank 11 serves as a storage container for lubricating grease. Its capacity is designed according to the production scale and grease application frequency of the equipment to ensure a sufficient supply of lubricating grease within a certain production cycle. The pressure controller 12, installed on the connecting pipe between the grease storage tank 11 and the grease supply device 13, is one of the core components ensuring the stability of the grease application process. During grease application, the pressure controller 12 monitors and controls the pressure of the lubricating grease in the connecting pipe. When the grease application nozzle 51 requires different grease spray pressures, the pressure controller 12 adjusts according to the instructions of the control system or preset pressure parameters. For example, when greases workpieces with rough surfaces or high requirements for lubricating grease penetration, the pressure controller 12 increases the pressure, allowing the lubricating grease to be sprayed from the grease application nozzle 51 at a higher speed and pressure, ensuring that the grease can fully fill the tiny gaps and rough surfaces of the workpiece, achieving a good lubrication effect. The grease supply device 13 is responsible for delivering the lubricating grease from the grease storage tank 11 to the grease application nozzle 51 as required. It receives lubricating grease regulated by pressure controller 12 and steadily pushes it to grease nozzle 51 through an internal delivery structure, such as a gear pump or plunger pump. Throughout the grease application process, all components of the grease supply system 1 work together to ensure that grease nozzle 51 can continuously and stably output lubricating grease at the required pressure and flow rate, thereby ensuring the consistency and reliability of the grease quantity, meeting the grease application needs of different workpieces, and improving the overall performance and production efficiency of the device.

[0053] Example 2

[0054] This embodiment is an optimization based on embodiment 1.

[0055] See Figures 1-6 Specifically, in this embodiment, the visual inspection system 4 includes a first guide rail 41, a first slider 43, and a visual lens 42. The first guide rail 41 spans above the conveyor line, and a plurality of first sliders 43 are provided on the first guide rail 41. Each first slider 43 is provided with a visual lens 42, and the visual lens 42 is positioned facing the conveyor line.

[0056] In actual use, multiple vision lenses 42 distributed on the first guide rail 41 simultaneously capture images of the components from multiple angles, obtaining complete image information of the components and immediately transmitting it to the central control computer. The computer uses image processing software to analyze the images, identifying the type, size, shape characteristics, and current grease application status of the components.

[0057] The vision lens 42 can slide on the first guide rail 41 via the first slider 43, enabling it to acquire structural features of different parts of the workpiece. During the grease application process, the vision lens 42 continuously monitors the grease application. If uneven grease application, grease accumulation, or missed areas are detected, it immediately reports this to the control system. The control system will then pause the grease application operation, fine-tune the grease parameters, and restart the grease application process until the grease quality meets the standard requirements.

[0058] Example 3

[0059] This embodiment is an optimization based on embodiment 1.

[0060] See Figures 1-6 Specifically, two clamps 3 are provided, and the two clamps 3 are arranged opposite each other on opposite sides of the conveyor line.

[0061] This embodiment also provides a specific structure of the clamp 3, which includes a bracket 32, a pneumatic gripper 31 and a rotation drive system. The bracket 32 ​​is disposed on one side of the conveyor line, and the pneumatic gripper 31 is rotatably disposed on the bracket 32.

[0062] The rotation drive system is mounted on the bracket 32, and the rotation drive system drives the pneumatic gripper 31 to rotate on the bracket 32.

[0063] More specifically, the rotation drive system includes a drive motor 35, a turntable 34, and a transmission belt 33. The drive motor 35 is fixed on the bracket 32. The turntable 34 is rotatably mounted on the bracket 32, and one side of the turntable 34 is fixedly connected to the pneumatic gripper 31 via a connecting shaft. The transmission belt 33 is connected between the output end of the drive motor 35 and the turntable 34.

[0064] The pneumatic gripper 31 is made of alloy steel with large clamping force and good wear resistance. It is mounted on the bracket 32 ​​by a pin. Its gripping surface can be equipped with a buffer pad such as rubber, so that the pneumatic gripper 31 can clamp the air guide plate without damaging the surface of the air guide plate.

[0065] When the workpiece (air guide plate) arrives at the grease application station, the clamps 3 on both sides move simultaneously under the command of the control unit. The pneumatic grippers 31 quickly clamp the workpiece under air pressure, ensuring that it does not shift during the grease application process. Subsequently, the drive motor 35 of the rotation drive system starts, driving the turntable 34 to rotate via the transmission belt 33, which in turn drives the pneumatic grippers 31 to rotate on the bracket 32, so that the connecting shaft of the air guide plate can receive the grease application operation evenly.

[0066] After the grease is applied, the drive motor 35 reverses, causing the pneumatic gripper 31 to return to its initial position. Then, the pneumatic gripper 31 releases the workpiece, and the greased workpiece leaves the grease station under the drive of the conveyor line, entering the subsequent quality inspection and assembly process, thus completing a complete grease application process.

[0067] This application uses two opposing clamps 3 to apply clamping force simultaneously from both sides of the workpiece. Compared to a single clamp 3, this significantly enhances the fixation of the workpiece, making it more stable during the grease application process and effectively preventing uneven or biased grease application caused by workpiece movement. Simultaneously, the rotation drive system of the clamps 3 ensures that the workpiece rotates at a uniform speed during grease application, guaranteeing that the grease nozzle 51 can apply grease to the workpiece surface from all angles. This results in a more uniform and comprehensive grease application, improving the lubrication quality of the product and extending the service life of the drive shaft.

[0068] Example 4

[0069] This embodiment is an optimization based on embodiment 1.

[0070] See Figures 1-6 In this embodiment, two grease coating structures 5 are provided, and the two grease coating structures 5 are arranged opposite each other on opposite sides of the conveyor line.

[0071] In this embodiment, the grease coating structure 5 further includes a second guide rail 535, a second slider (not shown), and a grease coating box 53. The second guide rail 535 is disposed on one side of the conveyor line, and the length direction of the second guide rail 535 is the same as the conveying direction of the conveyor line. The second slider is disposed on the second guide rail 535, and the grease coating box 53 is fixed on the second slider.

[0072] It should be noted that the principle of the first slider moving on the first guide rail in this application is the same as the principle of the second slider moving on the second guide rail, and both can be implemented using a linear guide rail slider mechanism.

[0073] The grease box 53 is provided with a toothed plate 532, a transmission gear 534 and a linear drive structure 533. The linear drive structure 533 is fixed inside the grease box 53, and the output end of the linear drive structure 533 is fixedly connected to the toothed plate 532. The transmission gear 534 is rotatably disposed inside the grease box 53, and the toothed plate 532 meshes with the transmission gear 534.

[0074] A transmission pipe 531 is provided in the middle of the transmission gear 534. One end of the transmission pipe 531 is exposed outside the grease box 53. The grease nozzle 51 is provided on the transmission pipe 531. The transmission pipe 531 is externally connected to the grease supply system 1. The grease nozzle 51 is also provided with a sensor 52, which is fixed on the transmission pipe 531.

[0075] Specifically, the linear drive structure 533 inside the grease tank 53 uses a high-precision electric push rod with a stroke of 50 cm and a thrust of up to 200 N, capable of precisely moving the gear plate 532. The linear drive structure 533 can also be a cylinder. The gear plate 532 and the transmission gear 534 are made of high-strength alloy steel, precision machined and heat-treated to ensure high meshing accuracy and durability. A transmission pipe 531 is installed in the middle of the transmission gear 534. The transmission pipe 531 is made of stainless steel with an inner diameter of 4 mm to ensure smooth grease delivery. The grease nozzle 51 needs to ensure uniform grease spraying.

[0076] When the air guide plate reaches the grease application station, the grease application structures 5 on both sides start simultaneously under the command of the central control system. First, the grease application box 53, driven by the second slider, moves to the appropriate position on the second guide rail 535 according to the structure of the air guide plate and the grease application position requirements. This ensures that after the clamp 3 clamps the air guide plate, the grease application nozzle 51 can be aligned with the connecting shaft of the air guide plate to ensure normal grease application. During the grease application process, the linear drive structure 533 pushes the toothed plate 532 to move, and the toothed plate 532 drives the transmission gear 534 to rotate, thereby causing the transmission pipe 531 and the grease application nozzle 51 to rotate; and the grease supply system 1, under the action of the pressure controller 12, delivers lubricating grease to the grease application nozzle 51 through the transmission pipe 531 at a stable pressure and flow rate. It can also spray lubricating grease onto the surface of the connecting shaft of the air guide plate by controlling grease application parameters, such as spraying time and spraying volume. During the grease application process, the vision inspection system 4 continuously monitors the grease application status. If problems such as uneven grease application, grease accumulation, or missed application are found, it immediately feeds back to the central control system. The central control system will adjust the grease application parameters in a timely manner, such as changing the angle of the grease application nozzle 51, increasing or decreasing the amount of grease sprayed, or pausing the grease application operation for correction.

[0077] In this embodiment, a recycling box 54 is provided below the transmission pipe 531, and the recycling box 54 is connected to the grease supply device 13.

[0078] In the actual grease coating process, when the device starts operating, lubricating grease is delivered from the grease supply device 13 through the transmission pipe 531 to the grease coating nozzle 51 to coat the workpiece. Since excessive grease spraying or grease slippage due to the workpiece surface structure may occur during the grease coating process, the recovery box 54 can recover the excess or slipped grease.

[0079] The recovery box 54 is positioned to effectively collect dripping grease. More preferably, the orthogonal projection of the transfer pipe 531 within the recovery box 54 should be located inside the box to ensure maximum catching of lubricating grease overflowing from around the transfer pipe 531 and during the grease application process. Since the recovery box 54 is connected to the grease supply device 13, the recovered lubricating grease can be returned to the grease supply device 13 via a specially designed piping and pumping system (e.g., using corrosion-resistant hoses and equipped with a small gear pump for grease delivery). The grease supply device 13 is equipped with a filtration and purification system. When the recovered grease re-enters, it is filtered to remove any impurities that may be mixed in, such as tiny metal fragments and dust from the workpiece surface. It is then purified, and its viscosity and performance parameters are adjusted to meet the quality requirements for grease application again.

[0080] Example 5

[0081] See Figures 1-6 This embodiment provides a workpiece grease application method, which is implemented based on the automatic grease application device described above.

[0082] The working process of this method is as follows:

[0083] Place the air guide plate to be coated at the beginning of the conveyor line and start the device. The air guide plate moves along the conveyor line to below the vision inspection system 4. The vision inspection system 4 quickly acquires the image information of the air guide plate and transmits it to the device's control system.

[0084] Based on the visual inspection results, the clamp 3 at the grease application station starts working, firmly holding the air guide plate. Driven by the control system, the grease application structures 5 on both sides move to the appropriate positions and adjust the angle of the grease application nozzles 51. Grease is then applied to the connecting shaft of the air guide plate.

[0085] During the grease application process, the grease nozzle 51 rotates to spray different positions on the connecting shaft. Additionally, the recovery box 54 below the transfer pipe 531 collects excess grease generated during the grease application process in real time. This recovered grease is then transported back to the grease supply device 13 through a connecting pipe for filtration and reuse.

[0086] After the grease application is completed, the vision inspection system 4 re-inspects the bearing grease application to check whether the grease is even and whether there are any missed areas. If the grease application quality is qualified, the clamp 3 releases the air guide plate, and the greased air guide plate leaves the grease application station under the conveyor line and enters the subsequent assembly process; if a grease application quality problem is detected, the system will issue an alarm and send the air guide plate back to the grease application station for re-grease application or manual intervention.

[0087] Additionally, it should be noted that the visual judgment algorithm used in this application to re-inspect the bearing grease application through the visual inspection system 4 is not a key point of protection in this application; therefore, the process of visual inspection and judgment will be described in detail.

[0088] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0089] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0090] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
