Description

Technical Field

[0001] This invention relates to the field of surface inspection technology, and in particular to a material surface inspection device and a batch automatic inspection device for materials including the same. Background Technology

[0002] When inspecting the surface quality of materials with cylindrical surfaces (such as cylindrical workpieces, bottles, and shaft parts), line scan cameras are widely used due to their advantages such as high imaging resolution, fast scanning speed, and good imaging effect on continuous curved surfaces. In practice, the material needs to be rotated at a uniform speed, and the line scan camera scans the cylindrical surface line by line and stitches them together to obtain a complete two-dimensional image, thereby obtaining clear, distortion-free surface details and providing accurate judgment criteria for defect identification (such as scratches, bubbles, and dirt).

[0003] Because line scanning imaging has strict requirements on the material position and speed during the detection process, surface inspection using line scanning cameras still largely relies on manual labor in the industry.

[0053] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0054] As mentioned in the background section, when inspecting the surface quality of cylindrical materials (such as cylindrical workpieces, bottles, and shaft parts) using a line scan camera, the material needs to be rotated at a uniform speed to scan the cylindrical surface line by line and stitch it into a complete two-dimensional image. This yields clear, distortion-free surface details, providing accurate judgment for defect identification (such as scratches, bubbles, and dirt). However, because line scan imaging has relatively strict requirements on the material's position and speed during the inspection process, surface inspection using line scan cameras still largely relies on manual labor in the industry. The development of automated inspection using line scan cameras is weak, resulting in poor inspection efficiency for large batches of materials.

[0055] Based on the above, the applicant of this invention has proposed a technical solution in the embodiments of this application. Specifically, by providing a material surface detection device and a batch automatic material detection device including the same, the surface detection of the material is realized through a mechanical structure, replacing the manual detection method performed by operators and greatly improving the detection efficiency.

[0056] The above is the core idea of ​​this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0057] like Figures 1-13As shown, this embodiment of the invention provides a material surface inspection device 10, which includes a base 1, a material conveying mechanism 2, a material fixing component 3, and an inspection mechanism 4. The material conveying mechanism 2 and the inspection mechanism 4 are both mounted on the base 1, and the material fixing component 3 is mounted on the material conveying mechanism 2. The base 1 is used to mount the material conveying mechanism 2 and the inspection mechanism 4, serving as the stable main body of the inspection device and the structural foundation for the integration of various mechanisms. The material conveying mechanism 2 is used to transport the material 100, enabling it to move to the corresponding position, thereby facilitating subsequent inspection, discharge, and other operations. The material fixing component 3 is used to fix the material 100 to the material conveying mechanism 2, ensuring structural stability during movement. The inspection mechanism 4 is used to perform surface inspection of the material 100.

[0058] Specifically, the material conveying mechanism 2 is movable relative to the base 1, so as to drive the material fixing member 3 from the detection position a to the discharge position b. The detection mechanism 4 includes a detection camera 41 and a detection auxiliary member 42. The detection camera 41 has a detection port. When the material fixing member 3 is at the detection position a, the detection port of the detection camera 41 can be set towards the outer peripheral surface of the material 100 fixed on the material fixing member 3, so that the detection camera 41 can take pictures of the outer peripheral surface of the material 100.

[0059] Furthermore, the material fixing component 3 includes a feeding column 31, which is rotatable around its own axis. A through hole 311 is provided at the axial position of the feeding column 31, one end of which is used to insert the material 100. When the material fixing component 3 is in detection position a, the detection auxiliary component 42 can be connected to the feeding column 31 to drive the feeding column 31 to rotate around its own axis.

[0060] In specific implementation, the detection camera 41 is a line scan camera, with its detection port facing the outer peripheral surface of the material 100, specifically the outer peripheral surface of the cylindrical portion of the material 100, for surface detection of this outer peripheral surface. Since the line scan camera needs to keep the material 100 in a rotating state to scan the material 100, the detection auxiliary component 42 is connected to the feeding column 31 via a transmission connection, which allows the material 100 to remain in a rotating state when it is at the detection position a, thereby facilitating the scanning of the surface of the material 100 by the detection camera 41.

[0061] For example, in one possible implementation, the detection auxiliary component 42 can be configured as a rotating component capable of rotating relative to the base 1. Specifically, the detection auxiliary component 42 can be driven by a drive motor to achieve active rotation. Furthermore, the detection auxiliary component 42 can contact the outer peripheral surface of the feeding column 31 located at the detection position. Thus, when the detection auxiliary component 42 rotates, it can drive the feeding column 31 to rotate synchronously through the frictional force between the auxiliary component 42 and the feeding column 31, thereby facilitating the detection camera 41 to acquire images of the outer peripheral surface of the material. See [link to details]. Figure 4 As shown. Of course, in other feasible ways, the detection auxiliary component 42 can also be connected to the feeding column 31 in other ways for transmission.

[0062] Based on the above, after the material 100 is inspected, it needs to be removed from the material fixing member 3. Therefore, the material surface inspection device 10 provided in this embodiment also includes a discharge mechanism 5, which is disposed on the base 1. When the material fixing member 3 is moved to the discharge position b by the material conveying mechanism 2, the discharge mechanism 5 is positioned towards the other end of the perforation 311. At the same time, the discharge mechanism 5 can also move towards the other end of the perforation 311 to abut against the material 100 and push the material 100 out of the perforation 311.

[0063] In practice, after the material 100 completes the inspection, it moves from the inspection position a to the discharge position b via the material conveying mechanism 2. At this time, the discharge mechanism 5 is correspondingly set with the material fixing part 3 for discharge operation. Since the material 100 is inserted at one end of the perforation 311, the discharge mechanism 5 moves towards the other end of the perforation 311, gradually approaching and contacting the material 100. During the continued movement, it pushes the material 100 gradually towards the outside of the perforation 311 until it is completely removed from the perforation 311. The material 100 can then fall off the material fixing part 3, making it convenient for operators to collect and sort.

[0064] It should be noted that since the detection process of material 100 is to detect first and then discharge, the discharge position b is located downstream of the detection position a. The upstream and downstream are determined by the movement direction of the material conveying mechanism 2 relative to the base 1. That is to say, the material fixing part 3 is first located at the detection position a, or the material conveying mechanism 2 first moves the material fixing part 3 to the detection position a, and then reaches the discharge position b during the continued movement.

[0065] Furthermore, the aforementioned detection position a and discharge position b, specifically, detection position a refers to the position of the material fixing member 3 relative to the base 1 when it moves to a position and surface that can be detected by the detection mechanism 4. Correspondingly, discharge position b refers to the position of the material fixing member 3 relative to the base 1 when the material 100 can be successfully pushed out by the discharge mechanism 5. These positions can be adaptively set according to the overall structural layout.

[0066] In summary, the material surface detection device 10 provided in this embodiment of the invention, by providing a material conveying mechanism 2 movable relative to the base 1 and a material fixing member 3 on the material conveying mechanism 2, allows the material conveying mechanism 2 to drive the material fixing member 3 to move from the detection position a to the discharge position b. Furthermore, a detection mechanism 4 is also provided on the base 1. When the material fixing member 3 is located at the detection position a, the detection camera 41 of the detection mechanism 4 can be positioned facing the outer peripheral surface of the material 100 to acquire images of the outer peripheral surface of the material 100. Simultaneously, the detection auxiliary member 42 of the detection mechanism 4 can interact with the material... The material feeding column 31 of the fixing member 3 is driven to make the material body 100 rotate, so that the detection camera 41 can collect circumferential images. Furthermore, when the material fixing member 3 moves to the discharge position b after the detection is completed, the discharge mechanism 5 provided on the base 1 can move toward the other end of the through hole 311 of the material feeding column 31 to abut against the material body 100 inserted at one end of the through hole 311 and push the material body 100 out of the through hole 311. In this way, the entire process of material transportation, detection and discharge is automated mechanical operation, and no operator is required to manually detect the material body 100, which greatly improves the detection efficiency.

[0067] Specifically, when the discharge mechanism 5 pushes the material body 100 out of the through hole 311 of the discharge column 31 by abutting against the material body 100, the abutment between the material body 100 and the discharge mechanism 5 can be direct or indirect, depending on the structure of the discharge column 31.

[0068] like Figure 7 As shown, in this embodiment, the material discharge mechanism 5 is indirectly contacted with the material body 100 to push the material body 100 out. Specifically, the material body fixing member 3 also includes a discharge pin 32, which is inserted at the other end of the through hole 311 and is movable along the axial direction of the through hole 311. When the material body fixing member 3 is in the discharge position b, the discharge mechanism 5 can move toward the discharge pin 32 to push the discharge pin 32 toward one end of the through hole 311, so that the discharge pin 32 contacts the material body 100 and pushes the material body 100 out of the through hole 311.

[0069] In other words, in this embodiment, a discharge pin 32 is inserted on the discharge column 31, which makes it easier for the discharge mechanism 5 to push the material 100 inserted in the perforation 311. With this arrangement, the discharge mechanism 5 and the discharge pin 32 can be contacted externally, which can reduce the accuracy requirements of the movement direction of the discharge mechanism 5 and ensure successful discharge.

[0070] Of course, in other embodiments, the discharge mechanism 5 can also directly contact the material body 100. For example, the discharge mechanism 5 can extend from the other end of the perforation 311 to contact the material body 100 and push the material body 100 to move. In specific implementation, the discharge mechanism 5 can be adaptively adjusted according to the specific structure.

[0071] For example, in one specific implementation, an elastic element can be provided between the perforation 311 and the discharge pin 32. In this way, when the discharge mechanism 5 pushes the discharge pin 32 to discharge the material 100, the discharge pin 32 can automatically return to the initial position, which makes it easier to insert the material 100 into the perforation 311 next time, thus improving the ease of use of the material fixing member 3.

[0072] In some embodiments, the discharge mechanism 5 may include a push rod 51 and a push rod 51 drive motor, wherein the push rod 51 is correspondingly arranged with the discharge needle 32, for example, coaxially arranged, and the push rod 51 drive motor is connected to the push rod 51 to drive the push rod 51 to reciprocate along its axial direction. This arrangement allows the drive motor to drive the push rod 51 to push the discharge needle 32, thereby achieving automated mechanical operation and improving ease of use.

[0073] Based on the discharge mechanism 5, in order to facilitate the collection of the material 100 after the test is completed, a material collection mechanism 6 can be further set on the base 1. The material collection mechanism 6 has a receiving port. When the material fixing part 3 is located at the discharge position b, the receiving port is set towards the end of the through hole 311.

[0074] In other words, when the feeding device moves the tested material 100 to the discharge position b, one end of the perforation 311 can face the receiving port on the material collection mechanism 6. At this time, the material 100 is pushed by the discharge mechanism 5, so that the material 100 comes out of the perforation 311 and falls directly into the material collection mechanism 6 through the receiving port. With this setting, the material can be unloaded without manual operation, realizing the automatic collection of the material 100. It also makes it easier for operators to take the tested material 100 in batches, making the whole testing process more efficient.

[0075] The aforementioned material collection mechanism 6 is used to collect the material 100 that has passed the test. For the material 100 that fails the test, it needs to be collected to another location for subsequent repair or disposal. Therefore, in some embodiments, the material surface inspection device 10 also includes a waste collection mechanism 7 for collecting the material 100 that fails the test.

[0076] like Figure 3 As shown, further, based on the detection position a and the discharge position b, the material conveying mechanism 2 can also move the material fixing member 3 to the waste disposal position c, and the waste disposal position c is located downstream of the detection position a along the moving direction of the material conveying mechanism 2. The waste collection mechanism 7 is set on the base 1, and the waste collection mechanism 7 is also provided with a waste disposal port. When the material fixing member 3 is located at the waste disposal position c, the waste disposal port of the waste collection mechanism 7 is set towards the end of the through hole 311.

[0077] In practice, the waste collection mechanism 7 can be located upstream of the material collection mechanism 6 or downstream of the material collection mechanism 6. The specific design can be adapted according to the actual structural layout.

[0078] Furthermore, regarding the configuration of the detection mechanism 4, in some embodiments, the number of detection mechanisms 4 can be two. The two detection mechanisms 4 are arranged at intervals along the moving direction of the material conveying mechanism 2, and there are two detection positions a. The material conveying mechanism 2 can drive the material fixing member 3 to move sequentially to the two detection positions a. Based on this, the two detection mechanisms 4 are each set corresponding to one detection position a. For details, please refer to [link / reference]. Figure 3 As shown.

[0079] By setting up two detection mechanisms 4, the material 100 can be tested twice. This not only improves the accuracy of the detection of the material 100, but also ensures that the detection process can continue if one of the detection mechanisms 4 fails to detect or is unable to work properly.

[0080] In practice, the material conveying mechanism 2 can drive the material fixing part 3 and the material 100 inserted in the through hole 311 to move to the first detection position a for the first detection. Then it moves to the second detection position a for the second detection mechanism 4 for the second detection. Finally, it moves to the discharge position b or the waste disposal position c to discharge the detected material 100 through the discharge mechanism 5.

[0081] It should be noted that setting up two detection mechanisms 4 can achieve the aforementioned effect of improving detection accuracy, or it can achieve higher detection precision. For example, the detection mechanism 4 located downstream can have higher detection precision, thus enabling different levels of detection of the material 100 and obtaining products with different precision.

[0082] Of course, in other embodiments, a greater number of detection units 4 may be provided, and the specific number can be adjusted according to actual needs.

[0083] In some embodiments, the material conveying mechanism 2 may include a material conveying tray 21, which is rotatably connected to the base 1 and can rotate around its own axis. A material fixing member 3 is disposed at the outer peripheral edge of the material conveying tray 21. Correspondingly, a detection mechanism 4 is disposed on the circumferential outer side of the material conveying tray 21 to correspond in position with the material fixing member 3 disposed at the outer peripheral edge of the material conveying tray 21.

[0084] In addition, the material collection mechanism 6 and the waste collection mechanism 7 are also located on the outer side of the conveying tray 21 in order to correspond with the material fixing member 3 located on the outer periphery of the conveying tray 21 when they are in different positions.

[0085] For example, the conveying tray 21 is a circular turntable, and the conveying mechanism 2 includes a conveying tray 21 drive motor and a connecting bearing 23. The conveying tray 21 is rotatably connected to the base 1 through the connecting bearing 23. At the same time, the conveying tray 21 drive motor is connected to the axis position of the conveying tray 21 to drive the conveying tray 21 to rotate relative to the base 1.

[0086] In order to improve the operating efficiency of the material conveying mechanism 2, in one specific implementation, the material conveying tray 21 can be set as a frame structure to further reduce its weight, thereby reducing the driving energy consumption of the drive motor of the material conveying tray 21.

[0087] In addition, the material fixing component 3 also includes a mounting base 33, through which the material dispensing column 31 is connected to the conveying tray 21. For example, the material dispensing column 31 can be detachably connected to the conveying tray 21 via the mounting base 33, thereby allowing different material fixing components 3 to be replaced according to different material 100 specifications, thus improving the flexibility of use of the material surface inspection device 10.

[0088] Based on the above, multiple material fixing parts 3 can be set up so that multiple material fixing parts 3 are arranged at intervals along the outer periphery of the conveying plate 21. In this way, multiple materials to be tested 100 can be passed through the position of the detection mechanism 4 in sequence by the rotation of the conveying plate 21, thereby improving the detection efficiency and automation of the detection equipment.

[0089] like Figure 1 and Figure 3 As shown, in some embodiments, the material conveying tray 21 can be arranged vertically, and the material conveying mechanism 2 can also drive the material fixing member 3 to move to the material release position d, which is located directly above the material conveying tray 21, and the material disposal position c is located directly below the material conveying tray 21 relative to the material release position d.

[0090] This configuration allows the material 100 to fall smoothly into the waste collection mechanism 7 under its own gravity while being discharged through the discharge mechanism 5, thus improving the success rate of waste collection. More importantly, the discharge position d and the waste disposal position c are vertically opposite each other. When the material 100 is inserted into the material fixing member 3 at the discharge position d, if the material 100 fails to be fixed and falls from the discharge position d, it can fall directly into the waste collection mechanism 7 at the corresponding waste disposal position c, thus achieving the collection of the failed-to-fix material 100.

[0091] Furthermore, in order to achieve automatic placement of the material 100, in some embodiments, the material surface detection device 10 further includes a feeding mechanism 8, which is used to place the material 100 into the perforation 311 of the feeding column 31.

[0092] Specifically, the feeding mechanism 8 includes a feeding seat 81, a drive assembly 82, and a pusher 83. The feeding seat 81 is disposed on the base 1 and has a feeding groove and a pusher hole 812 formed thereon. The feeding groove is used to place a plurality of materials 100 sequentially along its own length direction. The pusher hole 812 is located at one end of the feeding groove along its own length direction and is connected to the feeding groove. Furthermore, when the material fixing member 3 is in the feeding position d, one end of the pusher hole 812 is set towards one end of the through hole 311.

[0093] Specifically, the material 100 is placed in the discharge trough and inserted along the depth direction of the trough. Several material bodies 100 are placed sequentially along the length direction of the discharge trough. The push hole 812 is located outside one end of the discharge trough but is connected to the discharge trough. That is to say, the material body 100 in the discharge trough can move along the length direction of the discharge trough to the push hole 812 to form a state of being inserted into the push hole 812.

[0094] Based on the above, the drive assembly 82 is movable relative to the feeding seat 81 to push the material 100 in the feeding groove to the pushing hole 812. The pushing member 83 is located outside the other end of the pushing hole 812 and is disposed relative to the through hole 311. The pushing member 83 can move toward the pushing hole 812 to push the material 100 in the pushing hole 812 into one end inserted into the through hole 311.

[0095] In practice, the drive mechanism pushes the material 100 in the feeding trough to the pushing hole 812. Since the pushing hole 812 is set at one end facing the through hole 311, during the process of the pushing member 83 moving towards the pushing hole 812, the pushing member 83 can move to abut against the material 100 located in the pushing hole 812 and continue to push the material 100 towards the through hole 311 until it is inserted into the through hole 311. In this way, the material 100 is fixedly installed on the material fixing member 3 through the mechanical structure, which is conducive to the material surface detection equipment 10 to realize the automation of feeding.

[0096] In one specific implementation, the material 100 in the feeding trough is moved to the pushing hole 812 by the drive mechanism. A groove 811 is formed on the feeding seat 81. The bottom of the groove 811 extends through the groove wall of the feeding trough and the hole wall of the pushing hole 812. The drive assembly 82 includes a slider 821 and a first drive member 822. A slot 8211 is formed on the slider 821. The slot 8211 is used to lock onto the outside of the material 100. The slider 821 is located at the groove 811. The first drive member 822 is connected to the slider 821 to drive the slider 821 to slide relative to the groove 811, and the slot 8211 can move between one end of the feeding trough and the pushing hole 812.

[0097] For example, a chute 811 may be formed on the outer wall of the feeding seat 81 and extend from the outer wall of the feeding seat 81 to the position where the feeding groove and the pushing hole 812 are provided in the feeding seat 81. That is, the chute 811 communicates with the feeding groove and the pushing hole 812. Based on this, a slider 821 is provided at the chute 811, and a slot 8211 formed on the slider 821 can extend into the feeding groove and the pushing hole 812. Thus, when the slot 8211 on the slider 821 engages with the material 100 located in the feeding groove, the first driving member 822 can drive the slider 821 to move along the chute 811, thereby moving the material 100 located in the feeding groove into the pushing hole 812, so that the subsequent pushing member 83 can push the material 100 into the through hole 311.

[0098] Furthermore, such as Figure 12 As shown, a guide member 823 is also provided between the first driving member 822 and the slider 821, and the slider 821 is connected to the first driving member 822 through the guide member 823. The guide member 823 is provided with a guide groove 8231. When the first driving member 822 drives the guide member 823 to move, the slider 821 can move along the extension direction of the guide groove 8231.

[0099] Please continue reading Figure 12 As shown, in a specific implementation, the first driving member 822 drives the guide member 823 to move vertically, the slide groove 811 extends horizontally, and the guide groove 8231 has an inclined extension section. This inclined extension section can convert the vertical movement of the guide member 823 into the horizontal movement of the slider 821, thereby changing the driving direction. For example, the first driving member 822 can be a drive motor, with the transmission end of the drive motor connected to the guide member 823 to drive the guide member 823 to reciprocate vertically.

[0100] Of course, in other embodiments, the first driving element 822 can drive the slider 821 in other ways, such as by a lead screw.

[0101] Furthermore, the feeding mechanism 8 may also include a second driving member 84, which is connected to the pushing member 83 to drive the pushing member 83 to move toward the pushing hole 812. This enables automated installation of the material 100.

[0102] like Figure 3 As shown, in some embodiments, a material sensor 9 is also provided on the base 1. The material sensor 9 is located between the feeding mechanism 8 and the detection mechanism 4 and is used to detect whether the feeding mechanism 8 has successfully placed the material 100 on the material fixing member 3. In specific implementation, the material sensor 9 can be, for example, an infrared sensor or other sensors.

[0103] In some embodiments, the detection mechanism 4 further includes a first camera adjustment member 43 and a second camera adjustment member 44. The detection camera 41 is movably connected to the base 1 via the first camera adjustment member 43, allowing the detection camera 41 to move relative to the base 1 along a first direction. The detection camera 41 is also movably connected to the base 1 via the second camera adjustment member 44, allowing the detection camera 41 to move relative to the base 1 along a second direction.

[0104] Specifically, the first direction is the radial extension direction of the material 100 when the material fixing member 3 is located at the detection position a, and the second direction is parallel to the axial direction of the material 100 in the above state.

[0105] By setting the first camera adjustment component 43 and the second camera adjustment component 44, the imaging position of the camera can be adjusted simultaneously after the material fixing component 3 is replaced. This enables the camera to have a more accurate imaging effect for materials 100 of different specifications, and improves the flexibility of the material surface detection device 10.

[0106] Based on the above-mentioned structural configuration of the material surface detection device 10, the conveying tray 21 can move intermittently during operation. That is, the conveying tray 21 can make a short stop when it moves to the above-mentioned detection position a, discharge position b, waste position c and release position d. On the one hand, it can ensure the accuracy of the detection results, and on the other hand, it can improve the success rate of discharge and release.

[0107] Based on the above, the equipment also includes a control mechanism. This control mechanism is electrically connected to the drive motor of the conveying tray 21 of the material conveying mechanism 2, the drive motor of the push rod 51 of the discharge mechanism 5, the first drive component 822 and the second drive component 84 of the discharge mechanism 8, and the material sensing component 9, etc., thereby enabling automated operation of the material surface detection equipment 10 through signal reception and control of the entire equipment. Specifically, how the control mechanism controls the above-mentioned structures is existing technology and will not be explained here.

[0108] An embodiment of the second aspect of this application also provides an automatic batch material inspection device, which includes the material surface inspection device 10 described above. The relevant structural configuration of the material surface inspection device 10 has been described in detail in the above embodiments and will not be repeated here.

[0109] like Figure 1 As shown, in some embodiments, the batch automatic detection device for materials further includes a material feeding device. The material feeding device has a material feeding trough, which is used to place a plurality of materials 100 and drive the plurality of materials 100 to move along the extension direction of the material feeding trough. The material feeding trough can extend to the discharge trough of the discharge mechanism 8 and connect with the discharge trough.

[0110] In practice, the material handling equipment may include a storage bin, a handling platform 202, and a material transport rod 203, all of which are mounted on a mounting platform 204. The storage bin stores a large quantity of material 100, and its outlet is connected to the handling platform 202, allowing the material 100 to fall sequentially into it. The handling platform 202 organizes the material 100, ensuring all materials are arranged in the same position. Furthermore, a handling trough is formed on the material transport rod 203, and the outlet of the handling platform 202 is connected to the material transport rod 203, enabling the sorted material 100 to be delivered to the discharge trough.

[0111] Furthermore, the material transport rod 203 can be inclined toward the discharge chute of the discharge mechanism 8 so that the material 100 can generate a downward sliding force due to its own gravity. In addition, the material transport rod 203 can also be connected to the mounting platform 204 through the vibration device 205 so that the material 100 on the material transport rod 203 can be driven to move along the material chute.

[0112] It should be noted that the aforementioned material handling table 202 and vibration device 205 are existing technologies and will not be described in detail here.

[0113] In addition, the batch automatic detection device for materials provided in this embodiment should also include other modules or components that enable it to operate normally. Here, the other modules or components included in the batch automatic detection device for materials provided in this embodiment will not be described one by one.

[0114] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
