[0021] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] In automobile production lines, robots are increasingly being used in adhesive application processes.

[0024] In related technologies, it is often necessary to integrate a dedicated glue dispensing valve into the robot's operating end to control the start and stop of the glue application operation.

[0025] However, compared to manually used glue guns, dedicated glue dispensing valves are more expensive, resulting in a significant increase in the cost of glue application.

[0026] To address the aforementioned technical problems, this disclosure provides an adhesive application mechanism. This adhesive application mechanism is primarily used in robots on adhesive application production lines, enabling robots to apply adhesive using this mechanism.

[0027] like Figure 1As shown, the glue application mechanism includes a base 1, a clamping assembly 2, a glue application gun 3, and a drive assembly 4. The base 1 is used to connect to the robot. The clamping assembly 2 is connected to the base 1 and is used to fix the glue application gun 3. The drive assembly 4 is connected to the base 1 and is used to drive the glue application gun (3) to open or close.

[0028] The glue application mechanism provided in this embodiment can fix the glue gun 3 using the clamping component 2, and control the start and stop of the glue gun 3 using the drive mechanism. The base 1 is connected to the robot, allowing the robot to use the glue gun 3 for glue application without the need for a dedicated glue dispensing valve on the robot. Compared with a dedicated glue dispensing valve, the glue gun 3 has a lower cost, thereby reducing the cost of glue application.

[0029] Furthermore, the glue gun 3 is a handheld glue gun, a standardized, mass-produced mature product. Its procurement cost is far lower than that of dedicated glue dispensing valves commonly used in the industrial robot field, thus significantly reducing the equipment cost of glue application operations. At the same time, the glue cartridge replacement operation of the handheld glue gun 3 is relatively simple; operators can quickly change the glue cartridge without special training, which helps improve the production flexibility of the glue application production line. In addition, the glue gun 3 from the manual glue application production line can be recycled, further reducing the cost of the automated glue application production line.

[0030] In some embodiments, such as Figure 3 As shown, base 1 is a flange plate.

[0031] In this way, by setting a flange interface at the glue application end of the robot, the flange plate can be directly and securely installed at the glue application end of the robot with bolts, thereby enabling the entire glue application mechanism to move precisely with the robot.

[0032] Optionally, the flange plate is a circular or square plate with a positioning opening in its center for engaging with the positioning boss on the robot's end effector to achieve precise positioning. Multiple bolt holes are also distributed around the positioning stop on the flange plate, and the positions and dimensions of these bolt holes correspond one-to-one with the threaded holes on the robot's end effector flange.

[0033] Alternatively, the flange plate can be made of aluminum alloy with an anodized surface. This reduces overall weight and improves corrosion resistance while maintaining structural strength.

[0034] In some embodiments, such as Figure 1 As shown, the clamping assembly 2 includes two clamping plates 21, which are opposite to each other and connected to the base 1. The two clamping plates 21 are located on both sides of the gun body 31 to clamp the gun body 31 of the glue application gun 3.

[0035] In this way, the gun body 31 is clamped by two clamping plates 21 on both sides, which can fix the gun body 31 to prevent it from shaking during the movement of the robot's glue application end, thus ensuring the stability of the robot when applying glue using the glue gun 3.

[0036] Furthermore, the gun body 31 can be fixed using the two clamping plates 21, achieving fixation of the gun body 31 with a simple structure. The clamping cost of these two clamping plates 21 is low, thereby reducing the cost of the clamping assembly 2 and thus reducing the cost of the glue application operation. At the same time, the space required by the two clamping plates 21 is small, thereby reducing the size of the glue application mechanism to meet the miniaturization design requirements of the glue application mechanism.

[0037] Optionally, the surface of the clamp 21 that is in contact with the gun body 31 is adapted to the gun body 31, thereby ensuring the stability of clamping the gun body 31.

[0038] In some embodiments, combined with Figure 2 , Figure 3 As shown, the clamping assembly 2 also includes a connecting seat 23, which protrudes from the base 1 and is fixedly connected to the base 1. Two clamping plates 21 are respectively connected to the two sides of the connecting seat 23.

[0039] In this way, the two clamping plates 21 are fixedly connected to the base 1 via the connecting seat 23. On the one hand, the connecting seat 23 has a large contact area with the base 1, thus enabling it to stably abut against the base 1 and preventing the connecting seat 23 from wobbling relative to the base 1, thereby improving the stability of the clamping assembly 2 when the robot moves the glue gun 3. On the other hand, the two clamping plates 21 also have a large contact area with the connecting seat 23, thus enabling them to stably abut against the connecting seat 23 and preventing the possibility of the two plates wobbling relative to the connecting seat 23, thereby improving the stability of the clamping assembly 2 in clamping the gun body 31.

[0040] In some embodiments, combined with Figure 2 , Figure 3 As shown, the clamping assembly 2 also includes a plurality of second connectors 24 and a plurality of third connectors 25. The second connectors 24 pass through the connecting seat 23 and are connected to the base 1, and the third connectors 25 pass through the clamping plate 21 and are connected to the connecting seat 23.

[0041] In this way, the installation between the base 1, the connecting seat 23, and the clamping plate 21 can be achieved in a relatively simple way, thereby improving the convenience of assembling the clamping component 2 and the convenience of assembling the glue application mechanism.

[0042] Optionally, the third connector 25 passes through one of the clamping plates 21, the connecting seat 23, and the other clamping plate 21 in sequence. In this way, the two clamping plates 21 can be fixed by a third connector 25, thereby simplifying the structure of the clamping plates 21 and reducing the cost of using the connecting components.

[0043] Optionally, both the second connector 24 and the third connector 25 can be bolts.

[0044] In some embodiments, such as Figure 2 As shown, the clamping assembly 2 also includes a locking member 22, which is connected to the ends of the two clamping plates 21 away from the base 1.

[0045] In this way, after the two clamping plates 21 clamp the gun body 31 of the glue application gun 3, the ends of the two clamping plates 21 away from the base 1 can be connected by the locking member 22. This can prevent the two clamping plates 21 from deforming at this end and causing the two clamping plates 21 to loosen the gun body 31, thereby ensuring the stability of the clamping assembly 2 in clamping the gun body 31 and further reducing the possibility of the gun body 31 loosening during use.

[0046] Alternatively, the locking element 22 may be a bolt.

[0047] In some embodiments, such as Figure 2 As shown, the clamping assembly 2 includes a plurality of locking elements 22, which are arranged at intervals.

[0048] In this way, the stability of the two clamping plates 21 can be further improved by multiple locking parts 22, so as to further reduce the possibility of the gun body 31 coming loose during use.

[0049] In some embodiments, the clamping assembly 2 further includes two buffer pads, which are connected one-to-one to the surfaces of the two clamping plates 21 that are close to each other and abut against the gun body 31.

[0050] In this way, the clamping plate 21 abuts against the gun body 31 through the buffer pad, thereby increasing the friction between the clamping assembly 2 and the gun body 31, further improving the stability of the clamping assembly 2 in clamping the gun body 31, and further reducing the possibility of the gun body 31 coming loose during use.

[0051] Optionally, the cushioning pad can be, for example, but not limited to, a silicone pad or a rubber pad, and the embodiments disclosed herein are not limited thereto.

[0052] Optionally, the thickness of the cushioning pad can be 1mm to 5mm.

[0053] If the thickness of the buffer pad is less than 1 mm, the buffer pad is too thin and has poor deformation ability, which may result in less friction. If the thickness of the buffer pad is greater than 5 mm, the buffer pad is too thick, which may cause the buffer pad to deform excessively and cause the central axis of the gun body 31 to deviate from the expected position.

[0054] In this way, setting the thickness of the buffer pad to within the range of 1mm to 5mm can provide sufficient friction while avoiding the central axis of the gun body 31 from deviating from the expected position due to excessive thickness.

[0055] Optionally, the thickness of the cushioning pad can be, for example, but not limited to, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm, and the embodiments disclosed herein do not limit this.

[0056] Optionally, the surface of the buffer pad has multiple textures to increase the friction between the pad and the gun body 31, thereby further improving the stability of the clamping assembly 2 in clamping the gun body 31. These textures can be wavy, grid-shaped, or dotted raised.

[0057] Optionally, the cushioning pad is fixed to the inner surface of the clamping plate 21 by means of an embedded slot or adhesive backing. The embedded slot method involves creating a groove on the inner surface of the clamping plate 21, and the back of the cushioning pad has a protrusion that matches the groove. It is fixed by sliding insertion. This method is not easy to fall off during frequent disassembly and assembly, and it is also convenient to replace the cushioning pad when it is damaged.

[0058] In other embodiments, the clamping assembly 2 does not include two clamping plates 21, but includes a mechanical claw mechanism to clamp the gun body 31. Of course, the clamping assembly 2 can also have other structural forms, and this disclosure does not limit this.

[0059] like Figure 1 As shown, in some embodiments, the drive assembly 4 includes a drive member 41 and a pressing member 42. The drive member 41 is fixed to the base 1. The pressing member 42 is connected to the drive member 41 and is used to abut against the trigger 32 of the glue gun 3, wherein the drive member 41 is used to move in the direction of pulling or releasing the trigger 32.

[0060] Thus, by controlling the pressing component 42 to pull or release the trigger 32 via the drive component 41, the start and stop of the glue application operation can be controlled. This allows the robot to use the glue gun 3 for glue application without the need for a dedicated glue dispensing valve on the robot. Compared to a dedicated glue dispensing valve, the glue gun 3 has a lower cost, thereby reducing the cost of the glue application operation.

[0061] In some embodiments, combined with Figure 1 , Figure 3As shown, the driving component 41 is a cylinder. The cylinder includes a cylinder body 411 and a movable rod 412. The cylinder body 411 is fixed to the base 1, and the movable rod 412 is movably arranged inside the cylinder body 411 and connected to the pressing component 42.

[0062] In this way, simply opening the rodless cavity and evacuating the rod cavity allows the movable rod 412 to move the clamping plate 21 closer to the base 1; conversely, opening the rod cavity and evacuating the rodless cavity allows the movable rod 412 to move the clamping plate 21 away from the base 1. This allows for relatively simple control of the position of the pressing part 42 using a cylinder. Furthermore, the cylinder's small size facilitates miniaturization of the adhesive application mechanism.

[0063] Optionally, the cylinder is a double-acting cylinder with a bore of 32mm and a stroke of 20mm. While having a small size, this cylinder can deliver a large output force; for example, the output force can reach approximately 400N at a 0.5MPa air source pressure, which is sufficient to overcome the spring rebound force of the trigger 32 in most manual glue applicators on the market, ensuring that the trigger 32 can be reliably pressed into place.

[0064] In some embodiments, such as Figure 1 As shown, the glue application mechanism also includes two connectors 5, which are fixed to the base 1 and connected to the rodless chamber and the rod chamber of the cylinder, respectively, and are used to connect to the air pipes on the robot.

[0065] In this way, the cylinder can be connected to the robot through the two connectors 5, so that the robot can control the cylinder to adjust the position of the pressing part 42.

[0066] Optionally, the air pipe on the robot is equipped with a solenoid valve, which is electrically connected to the controller on the robot. The solenoid valve can control the connection or disconnection between the cylinder and the air pipe, thereby facilitating the adjustment of the position of the pressing component 42.

[0067] Optionally, the solenoid valve can be a two-position five-way solenoid valve, which has the advantages of small size and rapid switching, and can meet the cycle requirements for glue application start and stop.

[0068] Optionally, the solenoid valve is connected to the controller via a wired connection. Compared to a wireless connection, this avoids electromagnetic interference between the solenoid valve and other devices, thus enabling more stable control of the solenoid valve.

[0069] like Figure 1 As shown, the connector 5 also has an adjustment end 51, which can adjust the opening of the channel inside the connector 5.

[0070] In this way, the air intake or exhaust speed of the cylinder body 411 inside the cylinder can be adjusted using the adjustment end 51, thereby improving the stability of the movement of the movable rod 412. In specific applications, by adjusting the adjustment end 51, the extension and retraction speed of the cylinder movable rod 412 can be changed, thereby adjusting the speed at which the trigger 32 is pressed or released to adapt to the requirements of different adhesive viscosities or different adhesive application trajectories on the dispensing response speed.

[0071] Optionally, the adjusting end 51 is a rotary throttle valve. By turning it to change the airflow cross-sectional area, the speed of the cylinder extension and retraction can be adjusted independently, thereby controlling the release and pressing speed of the trigger 32 to adapt to the dispensing response requirements of different adhesive viscosities.

[0072] In some embodiments, combined with Figure 1 , Figure 3 As shown, the adhesive application mechanism also includes a guide 6, which is connected to the base 1 and is used to guide the movement of the pressing part 42.

[0073] In this way, the guide member 6 can constrain the pressing member 42 to prevent it from shaking during movement, thereby ensuring stable contact between the pressing member 42 and the trigger 32, and thus improving the stability of the pressing member 42 in controlling the trigger 32.

[0074] In some embodiments, such as Figure 3 As shown, both the pressing member 42 and the guide member 6 are plate-shaped. The pressing member 42 has a pressing end 421 and a guide end 422. The pressing end 421 is used to abut against the free end of the trigger 32. The guide member 6 is located on the side of the guide end 422 away from the pressing end 421 and is in contact with the guide end 422.

[0075] Since the cylinder moves in a telescopic motion, in order to prevent the pressing part 42 from shaking during the movement, the guide part 6 can be used to constrain the pressing part 42, so that the pressing part 42 can always move in a straight line, thereby ensuring stable contact between the pressing part 42 and the trigger 32, and improving the stability of the pressing part 42 in controlling the trigger 32.

[0076] Optionally, the guide plate has a protrusion at one end away from the base 1. The protrusion protrudes from the surface of the guide member 6 that is in contact with the pressing end 421, and is used to abut against the pressing member 42 to limit the pressing member 42.

[0077] This allows the guide plate to limit the movement of the pressing component 42, preventing excessive movement of the pressing component 42 and interference with other equipment.

[0078] Optionally, one of the pressing end 421 and the trigger 32 may be provided with a guide groove, and the other with a guide protrusion, with the guide protrusion engaging in the guide groove. Through the cooperation of the guide groove and the guide protrusion, it can be ensured that the pressing part 42 will not slip laterally when it contacts the trigger 32, and always maintains effective pressure on the free end of the trigger 32.

[0079] Optionally, the surfaces of the guide member 6 and the pressing member 42 that are in contact are coated with a wear-resistant layer, such as a polytetrafluoroethylene or molybdenum disulfide coating, to reduce the friction when the two slide relative to each other, thereby reducing the load on the moving rod 412 and improving the smoothness of cylinder operation and service life.

[0080] like Figure 3 As shown, the press-fit part 42 has a weight reduction area 423, which can be a weight reduction notch or a weight reduction hole.

[0081] This reduces the weight of the pressing component 42, thereby reducing the weight of the adhesive applicator and thus reducing the external force exerted by the adhesive applicator on the robot, making it easier for the robot to adjust the position of the adhesive applicator.

[0082] Optionally, the weight reduction area 423 is a plurality of weight reduction holes opened along the length of the press-fit part 42, such as circular holes, elliptical holes or oblong holes.

[0083] In some embodiments, such as Figure 2 As shown, the adhesive application mechanism also includes a connecting plate 7 and a first connecting member 8. The connecting plate 7 is opposite to the base 1, and the first connecting member 8 passes through the connecting plate 7, the driving member 41, and the base 1 in sequence.

[0084] In this way, the connecting plate 7 and the base 1 clamp the driving component 41, and the first connecting component 8 passes through the connecting plate 7, the driving component 41 and the base 1 in sequence, thereby fixing the driving component 41. In addition, during the movement of the moving component driving the pressing component 42, the connecting plate 7 can limit the pressing component 42, thereby preventing the pressing component 42 from damaging the trigger 32, thus improving the stability of the glue gun 3 in use.

[0085] Optionally, in a specific implementation, the end face of the connecting plate 7 near the pressing member 42 can be used as the limit surface of the end stroke of the pressing member 42. When the movable rod 412 retracts and drives the pressing member 42 to move towards the gun body 31 to the limit position, the end face of the guide end 422 of the pressing member 42 just abuts against the upper surface of the connecting plate 7, thereby accurately controlling the maximum downward stroke of the trigger 32 and preventing damage to the return spring inside the trigger 32 due to overpressure.

[0086] like Figure 2 As shown, the adhesive coating structure includes multiple first connectors 8.

[0087] This improves the stability of the connection between the connecting plate 7 and the base 1, thereby improving the stability of fixing the drive component 41.

[0088] Optionally, the guide plate is fixedly connected to the base 1 via the connecting plate 7.

[0089] Optionally, the guide plate and the connecting plate 7 are integrally formed, that is, the guide plate is bent vertically upward from one edge of the connecting plate 7 to form an L-shaped bending part. This integral structure not only reduces the number of parts, but also improves the connection rigidity and positional accuracy between the guide plate and the connecting plate 7, which is beneficial to ensuring the guiding accuracy of the pressing part 42.

[0090] In other embodiments, the drive element 41 can be a motor. For example, the motor can be a linear stepper motor or a DC motor coupled with a lead screw and nut mechanism. By receiving pulse signals or analog signals from the robot controller, the motor can precisely control the linear displacement of the pressing element 42, thereby achieving precise control of the downward stroke of the trigger 32, and thus adjusting the glue flow rate of the glue gun 3. Of course, the drive element 41 can also be other structures, such as an electromagnet or a hydraulic cylinder, and this disclosure does not limit this.

[0091] The adhesive application mechanism provided in this disclosure has at least the following technical advantages: (1) Significant cost advantage: The core drive component of this device uses a standard small cylinder instead of a special dispensing valve. The remaining structural parts are all self-designed machined parts or standard parts, resulting in extremely low overall manufacturing cost, which perfectly meets the cost-sensitive needs of collaborative robot applications.

[0092] (2) Excellent lightweight and integrated design: Through an integrated design with the base 1 as the core, the drive component 4, clamping component 2, guide component 6, etc. are highly integrated, resulting in a compact structure that avoids complex brackets and redundant connectors. According to actual weighing, the overall weight of the mechanism is only 3kg, which is very suitable for collaborative robots with small loads, typically ranging from 5kg to 15kg. It will not excessively occupy the robot's effective load capacity, ensuring the flexibility and cycle time of the robot's operation.

[0093] (3) High reliability and easy maintenance: The mechanical structure of the mechanism is simple and robust, and the operating principle is intuitive. The cylinders and connectors 5 used are all commonly used industrial parts, which are highly reliable and easy to purchase and replace. The setting of the limit mechanism (guide 6 and connecting plate 7) prevents overtravel and protects the trigger 32 of the glue gun 3. During maintenance, only the air circuit and fasteners need to be checked.

[0094] (4) Simple control and easy integration: The movement of the mechanism is controlled by only one solenoid valve. The robot control system only needs to output a simple switching signal to realize the start and stop control of glue application. The integration programming with the robot body is very simple and does not require complex communication protocols or dedicated controllers.

[0095] (5) High versatility: The design concept of this glue application mechanism is not only applicable to the glue application gun 3 of the aforementioned model, but also can be conveniently fixed and driven by various brands and models of manual or pneumatic glue application guns 3 by adapting to different shaped fixing plates and pressing parts 42, and has high application value.

[0096] Based on the same concept, this disclosure also provides an adhesive application assembly, including an adhesive application gun 3 and the aforementioned adhesive application mechanism, wherein a clamping assembly 2 clamps the adhesive application gun 3.

[0097] The glue application mechanism provided in this embodiment can fix the glue gun 3 using the clamping component 2, and control the start and stop of the glue gun 3 using the drive mechanism. The base 1 is connected to the robot, allowing the robot to use the glue gun 3 for glue application without the need for a dedicated glue dispensing valve on the robot. Compared with a dedicated glue dispensing valve, the glue gun 3 has a lower cost, thereby reducing the cost of glue application.

[0098] In some embodiments, the glue-applying gun 3 includes a connected gun body 31 and a trigger 32. At least a portion of the gun body 31 is held by a clamping assembly 2, and the trigger 32 is located on the side of the gun body 31 away from the base 1. A drive assembly 4 is connected to the base 1 and is used to press the trigger 32 to move it closer to the gun body 31, or to release the trigger 32.

[0099] In this way, trigger 32 is movably connected to gun body 31. When drive component 4 presses down on trigger 32 and moves it closer to gun body 31, glue gun 3 will spray glue, thus enabling the robot to control glue gun 3 to apply glue to the area to be glued. After drive component 4 releases trigger 32, trigger 32 will spring back to its initial position, and glue gun 3 will stop dispensing glue. In this way, the robot can control the start and stop of glue gun 3.

[0100] Based on the same concept, this disclosure also provides an adhesive coating production line, including a robot and the aforementioned adhesive coating mechanism, with a base 1 connected to the robot.

[0101] Using the glue application production line provided in this embodiment, the robot can control the start and stop of the glue application operation through a drive mechanism, thereby enabling the robot to perform glue application using a glue gun 3 without the need for a dedicated glue dispensing valve. The glue gun 3 has a lower cost compared to a dedicated glue dispensing valve, thus reducing the cost of the glue application operation.

[0102] In the production line provided in this embodiment, one working process of the robot and the glue-applying mechanism is as follows: I. Initial / Standby State (Glue Application Interrupted) The robot control system provides an initial signal, controlling the external solenoid valve to allow air to flow through connector 5 connected to the rodless chamber and to exhaust air from connector 5 connected to the rod chamber. Compressed air enters the rodless chamber of the drive component 41 through connector 5 connected to the rodless chamber, pushing the movable rod 412 to extend fully. The movable rod 412 drives the pressing component 42 to move away from the gun body 31 until the pressing component 42 releases the trigger 32. The pressing component 42 disengages from the trigger 32 of the glue gun 3 or is in the released position. The trigger 32 resets under its own spring force, and the glue gun 3 is closed, dispensing no glue. The robot can carry the mechanism and move quickly and unloaded to the starting point of the operation.

[0103] II. Begin applying the adhesive. The robot moves to the predetermined starting position for the glue application operation. The robot control system sends an electrical signal to "start glue application," controlling the external solenoid valve to switch. After switching, the connector 5 connected to the rod chamber is vented, and the connector 5 connected to the rodless chamber is vented. Compressed air enters the rod chamber of the drive component 41 through the connector 5 connected to the rod chamber, pushing the movable rod 412 towards the retracting cylinder 411. The movable rod 412 drives the pressing component 42 to move towards the gun body 31 until the pressing component 42 contacts and pulls the trigger 32 of the glue application gun 3, causing it to overcome the spring force and press downward. When the movable rod 412 retracts to its limit position (the pressing component 42 abuts against the connecting plate 7), the trigger 32 is pressed to its maximum opening, the glue path inside the glue application gun 3 opens, and glue begins to be dispensed stably.

[0104] III. Adhesive Application Process With the movable lever 412 retracted within the cylinder 411, the glue gun 3 continuously dispenses glue. The robot moves smoothly and at a constant speed along a pre-programmed three-dimensional trajectory (such as a car body weld), achieving precise and continuous glue application.

[0105] IV. Finishing Actions for Applying Adhesive The robot moves to the predetermined end position of the adhesive application operation.

[0106] The robot control system sends an electrical signal to "end glue application," controlling the external solenoid valve to switch back to its initial state. That is, the connector 5 connected to the rodless chamber is re-ventilated, while the connector 5 connected to the rod chamber is vented. Compressed air re-enters the rodless chamber of the drive unit 41, pushing the movable rod 412 to extend rapidly. The pressing component 42 moves forward with the movable rod 412, quickly releasing its grip on the trigger 32 of the glue gun 3. The trigger 32 of the glue gun 3 springs back instantaneously under the action of the internal spring, closing the glue path and immediately stopping the glue application. The mechanism returns to its initial standby state, and the robot can move to the next work point or return to its original position.

[0107] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0108] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure. 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.

[0109] In the description of this disclosure, 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 generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this disclosure 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 disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0110] 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.

[0111] 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, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this disclosure.

[0112] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
