Description

Technical Field

[0001] The invention relates to the technical field of hemispherical gyroscope preparation, and in particular to a hemispherical resonator lip edge detection device. Background Art

[0002] The hemispherical resonator gyroscope has the characteristics of simple structure, high precision, high reliability, and long life. It has important application scenarios in the fields of military, aerospace, astronomy, and ocean. Its core component is a hemispherical thin-shell resonator. It mainly uses the metal coating layer on the electrode and the metal coating layer on the hemisphere to form a capacitive effect, and the resonator is electrostatically excited to form vibration. The rotation angle is obtained by detecting its vibration signal and calculating. The lip edge of the hemispherical resonator is the main vibration area, and its vibration characteristics determine the accuracy of the hemispherical gyroscope. When there are defects in the lip edge, it will cause frequency splitting and increased loss, which is not conducive to the vibration of the resonator; at the same time, it will cause differences in the electrode spacing of the capacitive effect, thereby affecting the accuracy of the gyroscope.

[0003] At present, the lip edge detection mainly includes microscopic morphology detection and projection detection. Microscopic morphology detection is to detect it under a microscope or a magnifying glass. The advantage of this method is that it can find subtle defects on the lip edge, but the disadvantage is that it lacks detection of the overall uniformity of the lip edge of the hemispherical resonator; projection detection is to project the lip edge of the hemispherical resonator after coating onto the grid line, and observe the overlap between the projection and the grid line to determine whether the lip edge is flat. This method can observe the overall situation of the lip edge, but it is difficult to detect the details of the lip edge and the uncoated hemisphere. By combining the two methods, the detection of subtle defects and overall uniformity of the lip edge can be achieved, but the detection efficiency is generally low and the detection method is relatively complex, and it requires more effort, which is not conducive to the quality detection of the hemispherical resonator.

[0004] In addition, with the development of technology, the size of hemispherical resonant gyroscope varies according to different application scenarios. At present, according to the size of the hemispherical resonator, it is generally divided into conventional hemispherical and micro hemispherical. Figure 1 As shown, it is formed by mechanical processing, including a hemisphere, an inner anchor column connected to the top of the inner wall of the hemisphere, and an outer anchor column connected to the top of the outer wall of the hemisphere. The diameter of the hemisphere is generally 20-50mm; the diameter of the micro hemisphere is generally ≤10mm, which is formed by blowing, including a hemisphere and a hollow anchor column formed by the inward depression of the top of the hemisphere, as shown Figure 2 As shown. Due to different processing techniques, their shapes are also different. At present, there is no device that can efficiently and easily complete the lip edge detection of various hemispherical resonators before and after coating. Rapid detection of the uniformity of the lip edge of a hemispherical resonator gyroscope is currently a major problem. Summary of the invention

[0005] In view of the problems in the background technology, the present invention proposes a hemispherical resonator lip edge detection device, which can efficiently and simply complete the lip edge detection of various hemispherical resonators before and after coating.

The plurality of photo sensors are evenly spaced along the circumference of the upper cover. The shading plate has a light-transmitting hole, and the light-emitting mechanism is arranged below the position of the shading plate corresponding to the light-transmitting hole. The upper cover is detachably connected to the upper surface of the sunshade, and there is an anti-light leakage structure between the upper cover and the sunshade to prevent light from leaking out between the two. When the lip edge of the coated hemispherical resonator is detected, the coated hemispherical resonator is arranged in the upper cover; when the lip edge of the transparent hemispherical resonator is detected, the transparent hemispherical resonator is arranged in the upper cover through a shading fixture, and the transparent hemispherical resonator cover is arranged in the shading fixture, and there is a gap between the shading fixture and the shading plate, the lip edge of the coated / transparent hemispherical resonator abuts against the shading plate, and the coated / transparent hemispherical resonator sets the light-transmitting hole cover therein, The photo sensor detects the light signal leaked from between the lip edge and the light shielding plate, and is electrically connected to the signal analysis module. The signal analysis module receives the light signals transmitted by multiple photo sensors and determines the overall uniformity and defects of the lip edge of the hemispherical resonator according to the sizes of the multiple light signals.

[0007] As a further improvement of the above technical solution: The shading plate includes a first shading plate, the light-transmitting hole includes a first light-transmitting hole opened on the first shading plate, and the coated / transparent micro-hemispherical resonator can cover the first light-transmitting hole; The shading plate also includes a second shading plate detachably connected to the first shading plate, and the second shading plate is provided with a first socket that cooperates with the inner anchor column of the conventional coated / transparent hemispherical resonator. The light-transmitting hole also includes a second light-transmitting hole opened on the second shading plate, and the conventional coated / transparent hemispherical resonator can set the second light-transmitting hole cover therein, and the second light-transmitting hole is connected to the first light-transmitting hole.

[0008] There are a plurality of first light-transmitting holes, and the plurality of first light-transmitting holes are evenly spaced along the hollow anchor column of the coated / transparent micro-hemispherical resonator and correspond one-to-one to the plurality of photosensitive elements; A plurality of second light-transmitting holes are provided, and the plurality of second light-transmitting holes are evenly spaced along the inner anchoring column of the conventional coating / transparent hemispherical resonator and correspond one-to-one to the plurality of photosensitive elements.

[0009] The shading fixture includes a first shading fixture for installing a transparent micro-hemispherical resonator. The bottom surface of the first shading fixture is provided with a first accommodating hole. The inverted transparent micro-hemispherical resonator is fixed in the first accommodating hole by an adhesive, and the lip edge of the transparent micro-hemispherical resonator is exposed outside the first accommodating hole.

[0010] The shading fixture also includes a second shading fixture for installing a conventional transparent hemispherical resonator. The bottom surface of the second shading fixture is provided with a second accommodating hole. The bottom of the second accommodating hole is provided with a second plugging hole that cooperates with the outer anchor column of the conventional transparent hemispherical resonator. The outer anchor column of the conventional transparent hemispherical resonator is inserted into the second plugging hole to fix the conventional transparent hemispherical resonator in the second accommodating hole, and the lip edge of the conventional transparent hemispherical resonator is exposed outside the second accommodating hole.

[0011] The light leakage prevention structure comprises an annular groove, which is arranged on the upper surface of the shading plate and matches with the bottom end of the upper cover, and the bottom end of the upper cover is clamped in the annular groove.

[0012] A plurality of first magnetic structures are provided in the annular groove, a plurality of second magnetic structures corresponding to the first magnetic structures are provided at the bottom of the upper cover, the plurality of second magnetic structures correspond to the plurality of photo sensors one by one, and the first magnetic structure is magnetically connected to the corresponding second magnetic structure.

[0013] The light emitting mechanism comprises a lamp bead and a lamp cover. The lamp cover is fixed at the lower end of the shading plate and has an opening facing upwards. The lamp bead is fixed in the lamp cover.

[0014] The upper cover comprises a mounting portion and a cover body integrally formed at the lower end of the mounting portion. The body of the photoreceptor is fixed on the mounting portion, and the probe of the photoreceptor passes through the cover body and is fixed to the body.

[0016] Compared with the prior art, the advantages of the present invention are: The hemispherical resonator lip detection device of the present invention forms a closed space between the lip of the coated hemisphere and the shading plate after the coated hemisphere is placed. At this time, light is emitted from the light emitting mechanism, and after passing through the shading plate, the cavity of the coated hemisphere is filled with light. If the circumferential uniformity of the hemispherical lip is good, the detection signal of the light sensor probe should also be uniform; if the circumferential uniformity of the hemispherical lip is poor (there are uneven phenomena such as notches, cracks, poor flatness, etc.), light will leak from the uneven places, and at this time, the light intensity signals detected by each probe will be different, so as to detect the circumferential uniformity of the lip.

[0017] When placing a transparent hemispherical resonator, there is a narrow gap between the fixture that holds the transparent hemispherical resonator and the shading plate. The inspection principle is the same as that of the coated hemispherical resonator. If the local uniformity is poor, more light will leak out and then be detected by the probe after passing through the gap between the fixture and the shading plate.

[0018] It can be seen that the present invention can efficiently and conveniently complete the lip edge detection of various types of hemispherical resonators before and after coating, so that during the preparation process of the hemispherical resonator, the device can be used to detect the circumferential uniformity of the hemispherical lip edge at any time, which is convenient for discovering the defects of the hemispherical resonator lip edge or the influence of the processing technology on its lip edge in advance. While the traditional detection method is inefficient and requires a lot of effort, the detection device of the present invention can use optical principles to quickly and conveniently detect the circumferential uniformity of the hemispherical resonator lip edge, thereby improving the detection efficiency.

[0037] The following describes the implementation modes of the present invention with reference to the accompanying drawings so that those skilled in the art can better understand the present invention and implement it. However, the enumerated embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments may be combined with each other, wherein the same components are represented by the same figure marks.

[0038] like Figure 1-Figure 9 As shown, this embodiment provides a hemispherical resonator lip edge detection device, including: Optical detection module 1 and signal analysis module 2, The optical detection module 1 includes a light emitting mechanism, a light shielding plate and a light sensing mechanism. The photosensitive mechanism includes an upper cover 14 and a plurality of photo sensors 13. The photo sensors 13 are fixed on the upper cover 14. The probe 131 thereof penetrates into the cavity of the upper cover 14. The plurality of photo sensors 13 are evenly spaced along the circumference of the upper cover 14. The shading plate has a light-transmitting hole, and the light-emitting mechanism is arranged below the position of the shading plate corresponding to the light-transmitting hole. The upper cover 14 is detachably connected to the upper surface of the shading plate, and a light leakage prevention structure is provided between the upper cover 14 and the shading plate to prevent light from leaking out from between the two. When the lip edge of the coated hemispherical resonator is detected, the coated hemispherical resonator is arranged in the upper cover 14; when the lip edge of the transparent hemispherical resonator is detected, the transparent hemispherical resonator is arranged in the upper cover 14 through a shading fixture, and the transparent hemispherical resonator cover is arranged in the shading fixture, and there is a gap between the shading fixture and the shading plate, the lip edge of the coated / transparent hemispherical resonator abuts against the shading plate, and the coated / transparent hemispherical resonator sets the light-transmitting hole cover therein. The photo sensor 13 detects the light signal leaked from between the lip and the light shielding plate, and is electrically connected to the signal analysis module 2. The signal analysis module 2 receives the light signals transmitted by multiple photo sensors 13, and determines the overall uniformity and defects of the lip of the hemispherical resonator according to the sizes of the multiple light signals.

[0039] After the coated hemisphere is placed, a closed space is formed between the lip of the coated hemisphere and the shading plate. At this time, light is emitted from the light emitting mechanism, and after passing through the shading plate, the cavity of the coated hemisphere is filled with light. If the axial uniformity of the hemisphere lip is good, the detection signal of the light sensor probe should also be uniform; if the circumferential uniformity of the hemisphere lip is poor (there are uneven phenomena such as gaps, cracks, poor flatness, etc.), light will leak from the uneven places. At this time, the light intensity signals detected by each probe will be different, so as to detect the circumferential uniformity of the lip.

[0040] When placing the transparent hemisphere, there is a narrow gap between the fixture for placing the transparent hemisphere and the shading plate. The inspection principle is the same as that of the coated hemisphere. If the local uniformity is poor, more light will leak out and be detected by the probe after passing through the gap between the fixture and the shading plate.

[0041] Therefore, the present invention can efficiently and conveniently complete the lip edge detection of various hemispherical resonators before and after coating, so that in the process of preparing the hemispherical resonator, the device can be used to detect the circumferential uniformity of the hemispherical lip edge at any time, which is convenient for discovering the lip edge defects or the influence of the processing technology on the lip edge in advance. While the traditional detection method is inefficient and requires a lot of effort, the detection device of the present invention can use optical principles to quickly and conveniently detect the circumferential uniformity of the hemispherical resonator lip edge, thereby improving the detection efficiency.

[0042] In this embodiment, Fig.10As shown, the shading plate includes a first shading plate 15, the light-transmitting hole includes a first light-transmitting hole 152 opened on the first shading plate 15, and the coated / transparent micro-hemispherical resonator can cover the first light-transmitting hole 152 therein; like Fig.11 As shown, the shading plate also includes a second shading plate 6 detachably connected to the first shading plate 15, and the second shading plate 6 is provided with a first socket 61 that cooperates with the inner anchor column of the conventional coated / transparent hemispherical resonator. The light-transmitting hole also includes a second light-transmitting hole 62 opened on the second shading plate 6, and the conventional coated / transparent hemispherical resonator can cover the second light-transmitting hole 62 therein, and the second light-transmitting hole 62 is connected to the first light-transmitting hole 152.

[0043] When testing a micro-hemispherical resonator, only the first shading plate 15 is needed. When testing a conventional hemispherical resonator, only the second shading plate 6 is needed to be added to the first shading plate 15. This is more efficient than replacing different shading plates according to resonators of different sizes.

[0044] In this embodiment, a plurality of first light-transmitting holes 152 are provided, and the plurality of first light-transmitting holes 152 are evenly spaced along the hollow anchor column of the coated / transparent micro-hemispherical resonator and correspond one-to-one to the plurality of photosensitive elements 13; There are a plurality of second light-transmitting holes 62 , and the plurality of second light-transmitting holes 62 are evenly spaced along the inner anchoring column of the conventional film-coated / transparent hemispherical resonator and correspond one-to-one to the plurality of photosensitive elements 13 .

[0045] Specifically, this embodiment designs the light-transmitting holes into four fan-shaped structures with equal areas, which can ensure that the emitted light intensity is the same when the sensors in each direction are detecting, and the four holes correspond to the four sensor positions on the wall, reducing the test error. The smaller fan-shaped spacing can increase the detection lip edge area. If the fan-shaped area is too small, the light cannot irradiate the lip edge; if the area is too large, too much light will be injected, reducing the accuracy of sensor detection and increasing the detection error. The appropriate fan-shaped area can ensure that there is an appropriate amount of light injected in all directions of the hemisphere, and at the same time ensure that there is no interference from other light when the sensor is detecting.

[0046] like Fig.12 As shown, the shading fixture includes a first shading fixture 4 for installing a transparent micro-hemispherical resonator. The bottom surface of the first shading fixture 4 is provided with a first accommodating hole 41. The inverted transparent micro-hemispherical resonator is fixed in the first accommodating hole 41 by an adhesive, and the lip edge of the transparent micro-hemispherical resonator is exposed outside the first accommodating hole 41.

[0047] like Fig.13As shown, the shading fixture also includes a second shading fixture 5 for installing a conventional transparent hemispherical resonator. The bottom surface of the second shading fixture 5 is provided with a second accommodating hole 51. The bottom of the second accommodating hole 51 is provided with a second plugging hole 52 that cooperates with the outer anchor column of the conventional transparent hemispherical resonator. The outer anchor column of the conventional transparent hemispherical resonator is inserted into the second plugging hole 52 to fix the conventional transparent hemispherical resonator in the second accommodating hole 51, and the lip edge of the conventional transparent hemispherical resonator is exposed outside the second accommodating hole 51.

[0048] Hemispherical resonators are generally made of quartz. Uncoated hemispherical resonators are more transparent in appearance, while coated hemispherical resonators have poor transmittance. In order to achieve circumferential uniformity detection of the lips of various hemispherical resonators, a shading fixture specifically for uncoated hemispherical resonators is designed to meet the test requirements. Transparent micro-hemispherical resonators can be fixed in their shading fixtures by fillers (hot melt adhesive); and conventional transparent hemispherical resonators have internal and external anchors, which can be fixed by opening a socket on the fixture that cooperates with the external anchor rod. In order to avoid the influence of the internal anchor on the assembly of its lip and the shading plate, a socket is also required on the shading plate. Only after the internal anchor is inserted can the hemispherical lip and the shading plate be abutted. The jig for mounting the hemispherical resonator is placed on the shading plate so that the lip edge of the hemispherical resonator abuts against the shading plate. The light leaking from the uneven part of the lip edge can be transmitted to the sensor probe through the gap between the jig and the shading plate, thereby realizing the detection of the circumferential uniformity of the lip edge. The jig can be used to block the light passing through other parts except the lip edge, thereby realizing the purpose of detecting the lip edge of the uncoated hemispherical resonator.

[0049] At the same time, a small gap should be set between the hemisphere surface and the special fixture to ensure that there is no damage to the spherical surface, and a smaller gap can reduce light loss.

[0050] Therefore, during the preparation process of the hemispherical resonator, the circumferential uniformity of the hemispherical lip can be detected at any time using a special fixture, which is convenient for discovering lip defects or the impact of the processing technology on the lip in advance.

[0051] Since the light transmittance of the coated hemisphere deteriorates, the coated hemispherical resonator does not require a special fixture and can be directly tested for the circumferential uniformity of its lip edge.

[0052] In this embodiment, the anti-light leakage structure includes an annular groove 151, which is opened on the upper surface of the sunshade and cooperates with the bottom end of the upper cover 14. The bottom end of the upper cover 14 is clamped in the annular groove 151 to fix the upper cover 14 and enhance light protection.

[0053] A plurality of first magnetic structures 155 are provided in the annular groove 151, and a plurality of second magnetic structures 144 corresponding one-to-one to the first magnetic structures 155 are provided at the bottom of the upper cover 14. The plurality of second magnetic structures 144 correspond one-to-one to the plurality of photo sensors 13. The first magnetic structure 155 is magnetically connected to the corresponding second magnetic structure 144 to fix the shading plate to the upper cover 14.

[0054] The magnetic structure can be used to further fix the upper cover on the one hand, and on the other hand, it can ensure that the surrounding light sensors and the corresponding light-transmitting holes are in the same position, ensuring that the device is airtight, reducing experimental errors, and reducing the complexity of the device.

[0055] In this embodiment, the light emitting mechanism includes a lamp bead 16 and a lampshade 17. A fixing hole 153 is opened on the shading plate for threaded connection with a fastener. The lampshade 17 is fixed to the lower end of the shading plate by the fastener and the opening faces upward. The lamp bead 16 is fixed in the lampshade 17.

[0056] The lamp bead and the ring groove are coaxially designed, and the lampshade serves as the outer shell of the lamp bead. The lampshade is fixed to the lower end surface of the sunshade plate through the three outer holes of the sunshade plate ring using screws 18.

[0057] The lampshade 17 is designed as a triangular structure, which can save space and reduce the size of the device.

[0058] like Fig.14 and Fig.15 As shown, in this embodiment, the upper cover 14 includes a mounting portion 146 and a cover body portion 147 integrally formed at the lower end of the mounting portion 146. Fig.16 1 is a structural diagram of the photoreceptor 13. The body 132 of the photoreceptor 13 is fixed on the mounting portion 146. The mounting portion 146 is a square column structure. The cover portion 147 is a cylindrical structure and is tangent to the four circumferential sides of the mounting portion 146. The probe 131 of the photoreceptor 13 passes through the through hole 142 provided in the cover portion 147 and is fixed to the body 132. The side of the mounting portion 146 is provided with a threaded hole 143 for threaded connection with the body 132 of the photoreceptor 13.

[0059] In addition, a photo sensor 13 is also installed on the top of the mounting portion 146. The probe of the photo sensor 13 on the top passes through the through hole 142 opened on the top surface of the mounting portion 146 and is fixed to its body. A copper column hole 141 is opened on the top of the mounting portion 146 for fixed connection with the body of the photo sensor 13 on the top. The body of the photo sensor 13 on the top is fixed to a top plate 11 through a stud 12.

[0060] The top photo sensor 13 can be used to detect the coating consistency of the same batch of coated resonators. If the coating thickness of the same batch of coated resonators is uniform, the light intensity detected by the top photo sensor 13 should not be much different. If the film thickness is different, the data read by the top photo sensor 13 will be greatly different.

[0061] The top of the light-shielding fixture extends upward to form a truncated cone 42 , and the bottom of the cavity of the cover body 147 extends upward to form a truncated cone cavity 148 , and the truncated cone 42 is inserted into the truncated cone cavity 148 .

[0062] By hollowing out a truncated cone cavity inside the cover body, the detection space can be reduced and the detection accuracy can be enhanced. At the same time, when detecting a transparent hemisphere with a special fixture, the side of the fixture's truncated cone is tangent to the side of the hollowed-out truncated cone cavity to achieve the positioning of the fixture, ensuring that the hemisphere and the lamp bead are on the same axis, thereby reducing experimental errors.

[0063] The bottom end of the side wall of the cover body is recessed inward to form a plurality of steps 145 , and a plurality of screws 18 are fixed on the shading plate. The plurality of screws 18 correspond to the plurality of steps 145 one by one, and the nut ends of the screws 18 abut against the corresponding steps 145 .

[0064] The optical detection module 1 further includes a base 20 . The shading plate is provided with connection holes 154 around it for passing screws 18 to fix the support rods 19 . The shading plate is supported on the base 20 by a plurality of support rods 19 .

[0065] The detection device of this embodiment further includes a display module 3 for displaying the analysis result of the signal analysis module 2 in the form of data.

[0066] like Figure 6 As shown, the detection process of the uncoated micro-hemispherical resonator (i.e., the transparent micro-hemispherical resonator 7) is as follows: Step 1: Apply hot melt adhesive filler in the first receiving hole 41 of the first light shielding fixture 4 , and gently place the transparent micro-hemispherical ball therein, so that the top of the transparent micro-hemispherical ball is fully connected to the first light shielding fixture 4 .

[0067] Step 2: Open the upper cover 14 , place the first light shielding fixture 4 containing the transparent micro-hemispheres on the first light shielding plate 15 , and ensure that the transparent micro-hemispheres cover the four first light-transmitting holes 152 on the first light shielding plate 15 .

[0068] Step three: close the upper cover 14, attach the upper cover 14 to the first light shielding plate 15 through the annular groove 151 on the first light shielding plate 15, and further fix the upper cover 14 by using a magnetic attraction device.

[0069] Step 4: Turn on the power, and the light is emitted from the lamp bead 16, and evenly passes through the lip edge of the hemispherical resonator after passing through the first light shielding plate 15. If there is a defect on the lip edge, the intensity of the transmitted light will increase, and it will eventually be detected by the light sensor.

[0070] Step 5: Read the serial port screen reading. The greater the light intensity detected by the light sensor, the smaller the corresponding reading. Through all-directional detection, the uniformity of the circumferential lip edge of the hemispherical resonator can be judged according to the light intensity. At the same time, the hemispherical resonator can also be rotated for further verification.

[0071] like Figure 7 As shown, for the coated micro-hemispherical resonator 8, since its light transmittance is poor after coating, no shading fixture is required, and step 1 can be skipped. After opening the upper cover 14, the coated micro-hemispherical resonator 8 is directly placed on the first shading plate 15, and it is ensured that the transparent micro-hemispherical resonator 8 covers the four first light-transmitting holes 152 on the first shading plate 15. The remaining steps are the same as the above example.

[0072] like Figure 8 As shown, the detection process of the uncoated conventional hemispherical resonator (i.e., conventional transparent hemispherical resonator 9) is as follows: Step 1: Apply hot melt adhesive filler in the second insertion hole 52 of the second shading fixture 5 , and gently place the transparent conventional hemisphere therein, so that the outer support column of the conventional transparent hemisphere is fully connected to the second shading fixture 5 .

[0073] Step 2: Open the upper cover 14, install the second light shielding plate 6 on the first light shielding plate 15, and ensure that the four second light-transmitting holes 62 correspond one-to-one with the four first light-transmitting holes 152, and then place the second light shielding fixture 5 containing a conventional transparent hemisphere on the second light shielding plate 6, and make the inner anchor column of the conventional transparent hemisphere snap into the first socket 61 on the upper surface of the second light shielding plate 6.

[0074] Step three: close the upper cover 14, and attach the upper cover 14 to the second light shielding plate 6 through the annular groove 151 on the second light shielding plate 6, and further fix the upper cover by using a magnetic attraction device.

[0075] Step 4: Turn on the power, and the light is emitted from the lamp bead 16, and evenly passes through the lip edge of the hemispherical resonator after passing through the first light shielding plate 15. If there is a defect on the lip edge, the intensity of the transmitted light will increase, and it will eventually be detected by the light sensor.

[0076] Step 5: Read the serial port screen reading. The greater the light intensity detected by the light sensor, the smaller the corresponding reading. Through all-directional detection, the uniformity of the circumferential lip edge of the hemispherical resonator can be judged according to the light intensity. At the same time, the hemispherical resonator can also be rotated for further verification.

[0077] like Fig. 9 As shown, for the conventional coated hemispherical resonator 10, since its light transmittance is poor after coating, no shading fixture is required, and step one can be skipped. After the second shading plate 6 is installed in step two, the coated conventional hemisphere is directly placed on the second shading plate 6, and the inner anchor column of the conventional coated hemisphere is inserted into the first socket 61 on the upper surface of the second shading plate 6, and the remaining steps are the same as the above example.

[0078] The embodiments described above are only preferred specific implementations of the present invention. This specification uses the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments" to refer to one or more of the same or different embodiments according to the present disclosure. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
