Description

Technical Field

[0001] This invention relates to the field of surface inspection of ultra-thin glass, and more specifically, to an inspection table suitable for large-size ultra-thin glass and an inspection device comprising the table. Background Technology

[0002] Currently, in the field of touch screen glass processing, a dedicated inspection table is typically used for the appearance inspection of large-size, ultra-thin glass. For example, invention patent CN218180713U discloses an inspection table for large-size touch screen glass, which includes an inspection table frame, a placement rack, connecting rods, vacuum suction cups, and a linkage cylinder. This inspection table is movably connected to the frame via the connecting rods, allowing the placement rack to rotate 180°, thus facilitating the inspection of both sides of the glass; simultaneously, the vacuum suction cups adsorb the glass, avoiding the risk of breakage caused by manual flipping.

[0003] However, in actual use, this large-size touchscreen glass inspection station has a drawback: the height of the mounting frame is fixed and cannot be adjusted to suit the height of the inspectors. Inspectors of different heights need to bend over, stand on tiptoe, or adjust their posture to adapt to the fixed viewing height when inspecting the same glass. Prolonged operation can easily lead to visual fatigue and physical strain, affecting inspection efficiency and comfort. Furthermore, the fixed height cannot meet the personalized needs of different operating habits or different inspection stations regarding the glass viewing angle. Summary of the Invention

[0004] The purpose of this invention is to provide an inspection table suitable for large-size ultra-thin glass and an inspection device containing the table. This inspection table is more likely to allow for a suitable inspection posture, improving the comprehensiveness and accuracy of the inspection. It also has good versatility and human-machine friendliness, and can adapt to inspectors of different heights and operating habits.

[0005] To achieve the above objectives, the present invention provides an inspection table suitable for large-size ultra-thin glass, characterized in that it includes a glass placement table, a rotating frame rotatably connected to the glass placement table via a rotating shaft, and a telescopic mechanism connected to the rotating frame via a universal damping ball joint. The glass is placed on a glass placement platform, which can rotate along a rotating axis, and the telescopic mechanism can drive the glass placement platform to rise and fall. The glass placement stage includes a placement stage body and a glass placement fixture fixedly connected to the placement stage body. A vacuum suction cup is provided on the side of the glass placement fixture that faces the glass, and the vacuum suction cup is used to adsorb the glass.

[0006] Preferably, multiple glass placement fixtures are provided, and the multiple glass placement fixtures are distributed around the circumference of the glass placement stage.

[0007] Preferably, the placement fixture has a cavity inside, and the vacuum suction cup is connected to the cavity through a deep hole; Along the outer periphery of the glass, multiple sheet placement fixtures are connected to a vacuum generator via connecting air pipes, which pass through the rotating shaft and connect to the vacuum generator.

[0008] The present invention also provides an inspection device including an inspection table suitable for large-size ultra-thin glass, and further including a device body, a support member slidably connected to a telescopic mechanism, and an inspection lamp disposed on the inner wall of the device body; Multiple inspection lights are provided, located on the top and sides of the device body.

[0009] Preferably, the inspection lamp includes a first inspection lamp and a second inspection lamp, and the inspection device is provided with an inspection zone, with the inspection lamp facing the inspection zone; The first inspection lamp is located on the side wall of the device body opposite to the opening, and the second inspection lamp is located on the top of the inspection device.

[0010] Preferably, the first inspection lamp includes a first lamp area and a second lamp area that are independently controlled, with the second lamp area located below the first lamp area.

[0011] Preferably, the support member is provided with a slide rail, and the telescopic mechanism is provided with a slider that cooperates with the slide rail.

[0012] The present invention also provides a method of using the testing device, comprising: Step 1: Pull the glass placement platform to the opening of the inspection device, adjust the glass placement platform to its initial state, and place the glass to be inspected on the glass placement platform; Step 2: Turn on the vacuum generator to adsorb the glass onto the glass placement stage; Step 3: Turn on the second inspection light and push the glass placement platform to the inspection area of ​​the inspection device; Step 4: Adjust the relative position of the glass and the inspector using the slider, telescopic mechanism, universal damping ball head and rotating shaft, and the inspector inspects the glass; Step 5: Pull the glass placement stage to the opening of the inspection device, adjust the glass placement stage to its initial state, turn off the vacuum generator, and remove the glass.

[0013] Preferably, in step 3, the operator inspects the top of the glass along a zigzag route; The width of the first inspection lamp is greater than the width of the glass.

[0014] Preferably, in step 4, different inspection requirements are met by combining and turning on multiple inspection lights.

[0015] According to the above technical solution, the present invention uses a vacuum suction cup to stably place glass onto the upper surface of a glass placement stage. The glass placement stage is rotatably connected to a rotating frame via a rotating shaft, allowing the glass placement stage to rotate around the axis of the rotating shaft. Through the rotating shaft, the glass placement stage can be flipped 360°, enabling in-situ inspection of both sides of the glass during the inspection process. Furthermore, thanks to the vacuum suction cup, the glass will not accidentally detach during the flipping process. Preferably, the rotating shaft is equipped with damping, ensuring that the tilt angle of the glass placement stage remains stable after rotation.

[0016] The lower part of the rotating frame is connected to the rotating shaft, while the upper part is connected to the telescopic mechanism through a universal damping ball joint.

[0017] A universal damping ball joint provides multi-dimensional rotation and maintains relative position damping. Internally, it typically includes a ball head, a socket, a spring, and friction plates or damping media. When an external force is applied to the glass placement stage, the universal damping ball joint allows the rotating frame, along with the glass placement stage, to tilt or rotate in any direction relative to the telescopic mechanism, such as pitching forward and backward, swaying left and right, and rotating obliquely. When the external force is removed, the friction generated inside the universal damping ball joint balances the gravitational torque of the glass placement stage and the glass, allowing the entire glass placement stage to stably maintain its tilt angle and remain stable. Therefore, this universal damping ball joint enables the glass to be positioned at any angle at any time, providing greater flexibility in adjusting the glass position. Inspectors can adjust the glass to the most comfortable and clearest viewing angle according to their individual vision and operating habits, eliminating blind spots.

[0018] The telescopic mechanism serves as the support and lifting power source for the entire inspection table. Its top is connected to the rotating frame via a universal damping ball joint, while its bottom is used to connect to the subsequent inspection device body or other frames.

[0019] The telescopic mechanism can be configured as a linear drive device such as a pneumatic cylinder, hydraulic cylinder, or lead screw module. Its main function is to drive the glass placement stage to move vertically up and down. The telescopic mechanism can be controlled via remote control, which can change the horizontal and vertical distance between the glass placement stage and the inspector's eyes. During use, the operator only needs to control the remote control to adjust the height of the glass through the telescopic mechanism, thereby obtaining a glass position suitable for the operator's height, or adjusting the telescopic mechanism to obtain the optimal observation distance when inspecting glass of different sizes or in different areas.

[0020] Therefore, this inspection table suitable for large-size ultra-thin glass, through the coordinated operation of a rotating shaft, a universal damping ball joint, and a telescopic mechanism, enables the glass placement platform to possess three independent movement capabilities: flipping, tilting at any angle, and lifting. These movements can be performed individually and their results can be combined, providing inspectors with greater operational freedom, making it easier to achieve suitable inspection postures, improving the comprehensiveness and accuracy of inspections. Furthermore, it possesses excellent versatility and ergonomics, adaptable to inspectors of different heights and operating habits.

[0021] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In this invention, unless otherwise stated, directional terms included in the terminology represent only the orientation of the term in its normal use or as commonly understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0025] See Figure 1An inspection table suitable for large-size ultra-thin glass includes a glass placement table 11, a rotating frame 13 rotatably connected to the glass placement table 11 via a rotating shaft 12, and a telescopic mechanism 15 connected to the rotating frame 13 via a universal damping ball head 14. The glass is placed on the glass placement platform 11, which can rotate along the rotating shaft 12, and the telescopic mechanism 15 can drive the glass placement platform 11 to rise and fall. The glass placement stage 11 includes a placement stage body and a glass placement fixture 61 fixedly connected to the placement stage body. A vacuum suction cup is provided on the side of the glass placement fixture 61 that faces the glass. The vacuum suction cup is used to adsorb the glass.

[0026] Through the implementation of the above technical solution, the glass can be stably placed on the upper surface of the glass placement stage 11 using a vacuum suction cup. The glass placement stage 11 is rotatably connected to the rotating frame 13 via a rotating shaft 12, allowing the glass placement stage 11 to rotate around the axis of the rotating shaft 12. The rotating shaft 12 enables the glass placement stage 11 to be rotated 360°, allowing for in-situ inspection of both sides of the glass during inspection. Furthermore, the vacuum suction cup prevents the glass from accidentally detaching during rotation. Preferably, the rotating shaft 12 is equipped with damping, ensuring that the tilt angle of the glass placement stage 11 remains stable after rotation.

[0027] The lower part of the rotating frame 13 is connected to the rotating shaft 12, while the upper part is connected to the telescopic mechanism 15 through the universal damping ball head 14.

[0028] The universal damping ball joint 14 provides multi-dimensional rotation and damping to maintain relative position. Internally, it typically includes a ball head, a socket, a spring, and friction plates or damping media. When an external force is applied to the glass placement stage 11, the universal damping ball joint 14 allows the rotating frame 13, along with the glass placement stage 11, to tilt or rotate relative to the telescopic mechanism 15 in any direction, such as pitching forward and backward, swaying left and right, and rotating obliquely. When the external force is removed, the frictional force generated inside the universal damping ball joint 14 balances the gravitational torque of the glass placement stage 11 and the glass, allowing the entire glass placement stage 11 to stably remain at the tilt angle and maintain stability. Therefore, the universal damping ball joint 14 enables the glass to be positioned at any angle at any time, providing greater flexibility in adjusting the glass position. This allows inspectors to adjust the glass to the most comfortable and clearest viewing angle according to their personal vision and operating habits, eliminating blind spots.

[0029] The telescopic mechanism 15 serves as the support and lifting power source for the entire inspection table. Its top is connected to the rotating frame 13 via the universal damping ball joint 14, while its bottom is used to connect to the subsequent inspection device body or other frames.

[0030] The telescopic mechanism 15 can be configured as a linear drive device such as a cylinder, hydraulic cylinder, or lead screw module. Its main function is to drive the glass placement stage 11 to perform vertical lifting and lowering movements. The telescopic mechanism 15 can be controlled by a remote control, which can change the horizontal and vertical distance between the glass placement stage 11 and the inspector's eyes. During use, the operator only needs to control the remote control to adjust the height of the glass through the telescopic mechanism 15, thereby obtaining a glass position suitable for the operator's height, or adjusting the telescopic mechanism 15 to obtain the optimal observation distance when inspecting glass of different sizes or in different areas.

[0031] Therefore, this inspection table suitable for large-size ultra-thin glass, through the coordinated operation of a rotating shaft, a universal damping ball joint, and a telescopic mechanism, enables the glass placement stage 11 to possess three independent movement capabilities: flipping, tilting at any angle, and lifting. These movements can be performed individually and their results can be combined, providing inspectors with greater operational freedom, making it easier to achieve a suitable inspection posture, improving the comprehensiveness and accuracy of the inspection, and exhibiting good versatility and ergonomics, adaptable to inspectors of different heights and operating habits.

[0032] In this embodiment, preferably, multiple placement fixtures 61 are provided, and the multiple placement fixtures 61 are distributed circumferentially along the glass placement stage 11.

[0033] The glass placement fixtures 61 are fixedly connected to the inner side of the glass placement stage, enabling them to contact the glass and perform positioning and adsorption functions. During use, the glass placement stage 11 is first tilted. This tilt is maintained by the damping action of the rotating shaft 12. When placing the glass, the operator can first place the bottom edge of the glass against the bottom edge of the glass placement stage 11, facilitating positioning. Then, the glass is gently pushed backward, causing its lower surface to conform to the multiple glass placement fixtures 61. The multiple glass placement fixtures 61 are distributed circumferentially around the glass placement stage 11, i.e., arranged around the edge of the area where the glass is to be placed. After the glass is placed, a vacuum generator is used to evacuate the vacuum suction cups, allowing the glass placement fixtures 61 to support and fix the glass circumferentially.

[0034] Preferably, for large rectangular glass, two placement jigs 61 can be provided on each side of the glass. These two placement jigs 61 are spaced apart along the direction of that side, so that the glass only contacts the placement jigs 61 at multiple discrete points on its edge. Compared to full-surface contact or continuous edge contact, discrete point contact greatly reduces the contact area between the glass and the jigs, thereby reducing the risk of scratches or edge cracks on the glass surface due to friction or impact during placement or flipping. Secondly, the spaced placement jigs 61 allow the parts of the glass not in contact with the jigs to be suspended, providing good airtight conditions for subsequent vacuum adsorption and facilitating the formation of a uniform stress distribution at the glass edge. Finally, this uniformly spaced layout allows the supporting force to be evenly distributed on the outer edge of the glass, maximizing the flatness of the ultra-thin glass under stress and preventing local bending deformation of the glass due to its own weight or adsorption force.

[0035] In this embodiment, preferably, the placement fixture 61 has a cavity, and the vacuum suction cup communicates with the cavity through the deep hole 62; Along the outer periphery of the glass, multiple sheet placement fixtures 61 are connected to a vacuum generator via connecting air pipes, which pass through the rotating shaft 12 and are connected to the vacuum generator.

[0036] Each placement fixture 61 is designed with a hollow structure, forming a cavity. One or more deep holes 62 are formed on the surface facing the glass. These deep holes 62 serve as the suction ports of the vacuum chuck and communicate directly with the cavity inside the placement fixture 61. When the vacuum system is activated, the air inside the vacuum chuck is drawn out, creating a negative pressure, which, under atmospheric pressure, firmly adheres to the edge of the glass.

[0037] The film placement fixtures 61 are interconnected via connecting air tubes and ultimately connected to an external vacuum generator. Preferably, each end of the film placement fixture 61 has a connecting hole 63, which allows for quick connection with the connecting air tube.

[0038] To prevent the connecting air tubes from getting tangled during the glass flipping process, the connecting air tubes will pass through the inside of the rotating shaft 12 after they are joined, and then connect to the vacuum generator.

[0039] The rotating shaft 12 is designed as a hollow tubular structure with a through hole 121 running along the axial direction inside. A tee connector can be installed inside the through hole 121. The two ends of the tee are connected to the connecting air pipes at both ends of the glass placement stage 11 that are connected to the plate placement fixture 61, and the other end extends out from the through hole 121 and is sealed to the connecting air pipe that converges on the outside of the glass placement stage 11. This connecting air pipe is finally connected to the vacuum generator.

[0040] In one embodiment, to avoid tangling of the connecting air tubes, the glass placement stage 11 can be required to rotate in both directions during operation, but not continuously rotate 360°. More preferably, a quick connector with a rotating function is provided at the connection between the connecting air tube and the tee. Under the action of this quick connector, the connecting air tube can rotate relative to the tee, so that the glass can be continuously rotated during the inspection process.

[0041] The present invention also provides an inspection device including an inspection table suitable for large-size ultra-thin glass, and further includes a device body 2, a support member 23 slidably connected to a telescopic mechanism 15, and an inspection lamp disposed on the inner wall of the device body 2. Multiple inspection lights are provided, located on the top and sides of the device body 2.

[0042] The main body 2 is the external frame and shell of the entire inspection device, typically constructed of metal profiles and protective plates, providing a stable mounting base and a clean inspection environment for the internal components. The support member 23 is fixedly mounted on the main body 2, providing sliding support for the telescopic mechanism 15. Specifically, the telescopic mechanism 15 is slidably connected to the support member 23, thereby enabling horizontal movement of the entire inspection table within the main body 2.

[0043] Inspection lamps are installed on the top and inner side walls of the device body 2. The top inspection lamp is mainly used to provide front illumination for inspecting reflective defects such as scratches, dirt, and water ripples on the glass surface. The side inspection lamp is preferably located on the back of the glass to provide backlighting for transmitted illumination, which can inspect for defects such as foreign objects, bubbles, and uneven light transmittance inside the glass. By arranging multi-angle light sources within the device, inspectors can flexibly select or combine different inspection lamps according to the type of defect to be inspected, thereby obtaining the best defect contrast and improving the accuracy and efficiency of the inspection.

[0044] In this embodiment, preferably, the inspection lamp includes a first inspection lamp 31 and a second inspection lamp 32, and the inspection device is provided with an inspection zone, with the inspection lamp facing the inspection zone; The first inspection lamp 31 is located on the side wall of the device body 2 opposite to the opening, and the second inspection lamp 32 is located on the top of the inspection device.

[0045] The testing device is designed as a box structure with one open side, meaning that the front is open and serves as a glass loading and unloading port, while the back, top, and two sides are enclosed walls.

[0046] Glass is inserted or removed through the opening. Once the glass is pushed into position, the operator will first pull the glass placement platform 11 to the opening position, then take out a piece of glass to be inspected and place it on the glass placement platform 11, and then push the glass placement platform 11 to push the glass into the inspection area inside the device body 2.

[0047] Since the remaining surfaces are all closed, the light will reflect off the inner wall of the device body after the inspection lamp is turned on. This closed structural design can refocus the scattered light into the inspection area, significantly improving the utilization rate of light energy and the overall illuminance within the inspection area. To improve the light focusing effect of the device body 2, preferably, the first inspection lamp 31 is located on the side wall of the device body 2 opposite to the opening, so that the inspection area is closer to the back of the device body 2, i.e., the inspection area has a certain depth.

[0048] By rationally configuring the illumination angle of the inspection lamps so that they are all focused on the inspection area, an inspection area with the highest illuminance and most uniform light distribution can be artificially created inside the device. As the operator pushes the glass deeper into the device body 2, the change in illuminance on the glass surface can be observed with the naked eye. When the glass enters the inspection area, the illuminance on the glass surface increases significantly. At this point, the operator can stop pushing the glass, allowing it to reliably stop within the inspection area.

[0049] Precisely placing the glass to be inspected within the inspection area can significantly improve the efficiency and accuracy of the inspection, avoiding missed defects due to insufficient or uneven lighting.

[0050] In this embodiment, preferably, the first inspection lamp 31 includes a first lamp area and a second lamp area that are controlled independently, with the second lamp area located below the first lamp area.

[0051] During the inspection of large-size glass, depending on the inspection needs of different areas or the varying sensitivity of the defects to light from different angles, inspectors can flexibly activate only the upper first light zone, only the lower second light zone, or both light zones simultaneously. For example, when inspecting defects at the bottom edge of the glass, it may be necessary to activate only the lower second light zone to avoid visual interference from the strong light from above; while when inspecting the top area, the first light zone can be activated alone.

[0052] The independent control function of the first and second lighting zones gives inspectors the ability to finely control the lighting environment, which helps to highlight specific types of defects, reduce reflection interference, and further improve the flexibility and accuracy of inspection.

[0053] In this embodiment, preferably, the support member 23 is provided with a slide rail 21, and the telescopic mechanism 15 is provided with a slider 22 that cooperates with the slide rail 21.

[0054] The inspector can first pull the entire inspection table out to the opening of the inspection device via the slide rail 21. In this position, the space is open and unobstructed, allowing the operator to easily and safely place large pieces of glass to be inspected onto the glass placement table 11. After placement, the slider 22 is pushed to smoothly push the glass, along with the entire inspection table, into the predetermined inspection area inside the device.

[0055] During the inspection process, the operator can also adjust the front and back positions of the glass by using the slide rail 21 as needed, and move different areas of the glass to the center of the inspection zone where the light is most concentrated and the visual conditions are most ideal for careful inspection.

[0056] The present invention also provides a method of using the testing device, comprising: Step 1: Pull the glass placement platform 11 to the opening of the inspection device, adjust the glass placement platform 11 to the initial state, and place the glass to be inspected on the glass placement platform 11. Step 2: Turn on the vacuum generator to adsorb the glass onto the glass placement stage 11; Step 3: Turn on the second inspection light 32 and push the glass placement stage 11 to the inspection area of ​​the inspection device; Step 4: Adjust the relative position of the glass and the inspector using the slider 22, telescopic mechanism 15, universal damping ball head 14 and rotating shaft 12, and the inspector inspects the glass. Step 5: Pull the glass placement stage 11 to the opening of the inspection device, adjust the glass placement stage 11 to the initial state, turn off the vacuum generator, and take out the glass.

[0057] First, the operator pulls the glass placement platform 11 out of the inspection device via the slide rail 21 until it reaches the opening of the inspection device. Then, the glass placement platform 11 is adjusted to its initial state. This initial state means that the glass placement platform 11 is in an inclined and high position. The lower end of the glass placement platform 11 can be used to position the lower end face of the glass. After the glass is pushed onto the glass placement platform 11, reliable positioning of the glass can be achieved. Moreover, under the action of its own weight, the glass can achieve self-balance on the glass placement platform 11.

[0058] After the glass is placed, the operator turns on the vacuum generator. The strong suction force will firmly fix the ultra-thin glass on the glass placement platform 11. Even during subsequent flipping and multi-angle tilting, the glass will not slip or shift.

[0059] After the glass is fixed, the operator turns on the inspection light as needed. Then, the glass placement platform 11 is smoothly pushed into the inspection device again via the slide rail 21 until the glass reaches the inspection area and obtains optimal illumination.

[0060] Afterwards, the inspectors began inspecting the glass. During this process, the operator can use the slider 22 to move the glass horizontally back and forth, the telescopic mechanism 15 to move the glass vertically up and down, the universal damping ball joint 14 to tilt and rotate the glass at any angle, and the rotating shaft 12 to flip the glass. Through the coordinated adjustment of these multi-degree-of-freedom mechanisms, the inspectors can present any area of ​​the glass at any angle and distance that they feel comfortable at within the optimal field of vision, thereby conducting a comprehensive, detailed, and blind-spot-free inspection of the glass surface.

[0061] After inspection, the operator pulls the glass placement stage 11 out to the opening of the inspection device again via the slide rail 21. Then, the glass placement stage 11 is returned to its initial state. The vacuum generator is turned off, and the suction force disappears. Finally, the operator can safely and easily remove the inspected glass from the glass placement stage 11.

[0062] In this embodiment, preferably, in step 4, the operator inspects the top of the glass along a zigzag route; The width of the first inspection lamp 31 is greater than the width of the glass.

[0063] The width of the first inspection lamp 31 is set to be greater than the width of the glass, so that the operator can inspect the glass surface of a certain width area by moving left and right in the original position, and then push the glass back and forth to inspect the glass of adjacent wide areas.

[0064] Once the glass is pushed into the inspection area, the entire glass surface is fully and evenly covered by the light source across its entire width. Therefore, operators do not need to move the glass left or right; they can simply observe from a fixed position using their eyes or auxiliary observation equipment to complete a comprehensive inspection of a specific horizontal strip area of ​​the glass in one go. This design allows the device to focus on ensuring full coverage in the width direction and coverage in the length direction of the inspection area, without having to designate the entire footprint of the large glass as a highly uniform illumination area. This significantly reduces the requirements for the size of the illumination system's light spot and the internal space of the device itself.

[0065] The operator inspects the upper surface of the glass along a zigzag route. In one embodiment, a certain width is inspected from the upper left to the upper right, then from the upper right down to the left, and so on until the entire glass surface is inspected.

[0066] In this embodiment, preferably, in step 4, different inspection requirements are met by combining and turning on multiple inspection lights.

[0067] During normal use, firstly, turn on the second inspection light 32, and the operator completes the first scan of the entire glass surface following a zigzag route, focusing on marking reflective defects such as surface scratches, dirt, and water ripples. Then, turn off the second inspection light 32, turn on the first inspection light 31, and perform a second scan along the zigzag route, focusing on transmissive defects such as internal foreign objects, bubbles, and uneven light transmission.

[0068] During the Z-shaped scanning inspection of a transverse strip of glass, a single light source often fails to provide optimal contrast for all types of defects. Therefore, this invention provides a flexible combined lighting control strategy. In actual inspection, some complex defects are difficult to identify accurately under a single light source. For example, minor surface scratches may not be clearly visible under a top light source, but by simultaneously activating the side backlight, the two lights superimpose, enhancing the visual sharpness of the defect. Therefore, operators can use their experience to simultaneously activate the top and side lights, while also adjusting the glass position, to achieve the best overall observation results. This mixed lighting mode is particularly suitable for inspecting touchscreen glass with multi-layered film structures or specially treated surfaces.

[0069] Therefore, for suspicious areas, the top light and side light can be turned on in combination, or the upper / lower light areas of the first inspection light 31 can be switched separately for verification.

[0070] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
