Description

Technical Field

[0001] This invention relates to the technical field of smart bracelet production, and in particular to a bonding machine for smart bracelet production. Background Technology

[0002] A smart bracelet is a wearable smart device. Through a smart bracelet, users can record real-time data on their daily activities, including exercise, sleep, and in some cases, diet, and synchronize this data with their mobile phones, tablets, and PCs. This allows for data-driven guidance for a healthier lifestyle. Smart bracelets have a built-in low-power Bluetooth module, enabling connection to mobile phones, tablets, and PCs. Users can set information such as height, weight, and stride length, and upload exercise data anytime, anywhere.

[0003] In the production process of smart bracelets, a screen protector needs to be applied to the surface of the screen of the finished bracelet body. The existing method of applying the screen protector is mainly done manually. Manual application is costly, and the existing method involves peeling the pre-cut film from the sticker and sticking it to the screen. Since the pre-cut film is the same size as the screen, slight misalignment during application can lead to misalignment, wrinkles, and air bubbles. In addition, fingerprints and palm prints can easily be imprinted on the display screen or the screen protector during the application process, reducing the aesthetics. Furthermore, fingerprints and palm prints need to be removed, making this inefficient method unsuitable for assembly line production.

[0004] Therefore, there is an urgent need for a bonding machine for smart bracelet production to solve the above-mentioned defects. Summary of the Invention

[0005] I. Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bonding machine for smart bracelet production, comprising a shell, a base mounted on the bottom of the shell, a liftable cutting module mounted on the base, a lifting plate located inside the cutting module connected to the base by a lifting cylinder, a bonding module mounted on the upper end of the lifting plate, a positioning module mounted on the upper end of the shell, and tensioning modules mounted on the left and right ends inside the shell. The bracelet body is placed into the positioning module for positioning and air suction, with the screen of the bracelet body facing down. The air-suction bracelet body is then lowered to a suitable position and then lifted... The bonding module lifts the conveyed long roll of film (with the adhesive layer facing up) upwards for bonding (the bonding trajectory is from the middle to both sides). After bonding, the bonding module descends and retracts back into its original position. Then, by the rising of the cutting module, the long roll of film is cut along the edge of the screen, thus obtaining a protective film that matches the screen. This protective film is then attached to the screen by the bonding module. The wristband body is embedded and positioned using air suction. Subsequently, the long roll of film is trimmed using automated film bonding and edge trimming. Compared to manual film bonding, this is more conducive to automated production lines.

[0007] The bonding module includes a middle frame, a bonding component, a pressing rod, a power supply unit, an electric slider, a moving frame, and a pressing component. The middle frame is mounted on a lifting plate. The upper end of the middle frame is equipped with a flexible, lifting bonding component, and the lower end of the bonding component is equipped with a pressing rod. Power supply units are symmetrically installed on the left and right ends of the middle frame. The power supply units are electrically connected to the electric slider on the lifting plate. The power supply units are pressed together with the pressing rod. The power supply units are disconnected when the pressing rod has not descended to its lowest position. A moving frame is installed on the electric slider. The upper end of the moving frame is equipped with a pressing component that is extendable. The pressing component is pressed together with the middle frame.

[0008] The pressing assembly includes a fixed base, a reset telescopic rod, a movable base, a first flexible layer, a pressing unit, an ejection unit, an angle plate, and a second flexible layer. The fixed base is mounted on a movable frame, and a reset telescopic rod connects the fixed base and the movable base. The reset telescopic rod always maintains an upward pushing tendency on the movable base. The first flexible layer is laid on the upper end of the movable base, and the pressing unit is installed on the side wall of the movable base. The front and rear ends of the movable base are hinged to the upper end of the angle plate. The second flexible layer is laid on the outer side wall of the angle plate. The flexible materials of the first and second flexible layers further improve the fit of the long strip film to the screen surface. An ejection unit is set between the fixed base and the movable base. The ejection unit controls the angle of the angle plate. When the ejection unit extends, it lifts the drooping angle plate, thereby forming a horizontally placed angle plate. The angle plate is hinged to the movable base, ensuring that the angle plate can be pushed to a horizontal state when the film is applied, so that the second flexible layer and the first flexible layer are on the same horizontal plane. When the film is not applied, the angle plate hangs down naturally, avoiding contact between the cutting module and the angle plate, and greatly reducing wear between them.

[0009] The cutting module described above includes a connecting cylinder, a knife holder, and a cutting blade. The connecting cylinder is installed inside the base, and the knife holder is installed at the upper end of the connecting cylinder. The position between the knife holder and the cutting blade is temporarily locked. The cutting blade with the appropriate structure is replaced for different specifications of the wristband body.

[0010] The aforementioned positioning module includes a positioning frame, a bottom positioning component, a bidirectional lead screw, a connecting seat, a motor, an L-shaped frame, a pneumatic positioning head, and a pushing cylinder. The positioning frame is installed in the upper middle part of the outer shell. Bottom positioning components are symmetrically slidably arranged at the left and right ends of the positioning frame. Connecting seats are symmetrically installed at the front end of the positioning frame. A bidirectional lead screw is connected between the connecting seats through bearings. The bidirectional lead screw and the bottom positioning component are connected by a threaded engagement. The rotation of the bidirectional lead screw drives the bottom positioning components to move in opposite directions or in the opposite direction. One end of the bidirectional lead screw is connected to the output shaft of the motor. The motor is installed on the outer wall of the positioning frame through a motor mount. An L-shaped frame is installed at the upper end of the positioning frame. A pushing cylinder is connected between the L-shaped frame and the pneumatic positioning head. The pneumatic positioning head has a built-in air pump, which is used to suction the wristband body onto the lower surface of the pneumatic positioning head.

[0011] The aforementioned tensioning module includes an electric roller and a sleeve. The electric roller is installed on the inner side wall of the rear end of the housing, and the sleeve is sleeved on the electric roller. The sleeve is slidably sleeved on the electric roller, and a long strip of film is wound between the sleeves arranged on the left and right.

[0012] The aforementioned bonding assembly includes a connecting plate, an elastic telescopic rod, and a flexible layer three. An elastic telescopic rod connects the connecting plate to the middle frame. The elastic telescopic rod always maintains an upward pushing trend on the connecting plate. A flexible layer three is laid on the upper end of the connecting plate. The flexible layer three is made of the same material as the flexible layer two.

[0013] The aforementioned power supply unit includes an insulating frame, a power source, a fixed conductive component, a movable conductive component, an insulating rod, and a compression spring. The insulating frame is mounted on the lifting plate. The power source, fixed conductive component, and movable conductive component inside the insulating frame are electrically connected to the electric slider. The movable conductive component is movably mounted inside the insulating frame. An insulating rod is installed at the inner end of the movable conductive component, and a compression spring connects the insulating rod to the lifting plate.

[0014] As described above, the compression spring always maintains an upward pushing tendency on the insulating rod, the insulating rod and the compression rod are always in contact, and the movable conductive part and the fixed conductive part are in a separate state at the initial position.

[0015] As described above, the movable frame is symmetrically provided with sliders at both the front and rear ends. The sliders are slidably mounted on the slide rails, which are installed on the edge of the lifting plate. The sliders and slide rails work together to provide auxiliary support for the sliding of the movable frame on both sides.

[0016] The extrusion unit described above includes an extrusion plate and an extrusion roller. One end of the extrusion plate is mounted on a movable seat, and the other end of the extrusion plate is provided with a rotatable extrusion roller. Extrusion grooves are symmetrically opened at the left and right ends of the middle frame. The extrusion grooves and the extrusion rollers are in extrusion contact. The inclined surface of the extrusion grooves gradually slopes downward from the outside to the inside. The opening of the extrusion grooves is mainly to cooperate with the extrusion unit, so as to lock the height of the movable seat when it is not in use.

[0017] The aforementioned ejection unit includes a pusher frame, a connecting roller, and an extrusion block. The pusher frame is slidably mounted on a movable seat, and a rotatable connecting roller is provided at the lower end of the pusher frame. The connecting roller contacts the outer surface of the extrusion block, and the extrusion block is mounted on a fixed seat.

[0018] As mentioned above, the middle part of the outer side of the extrusion block has a structure that gradually slopes inward from top to bottom, which reduces the difficulty of extrusion between it and the connecting roller.

[0019] As described above, the angle plate and the side wall of the fixed seat are magnetically attracted. The magnetic attraction has a certain attraction force, but they can be separated when the squeezing force is greater than the attraction force. Under the forced squeezing of the push frame, the angle plate separates from the side wall of the fixed seat and is then placed horizontally. When the push frame retracts, the angle plate falls naturally under the action of gravity and is then attracted to the side wall of the fixed seat under the magnetic attraction force.

[0020] II. Beneficial Effects

[0021] 1. The present invention discloses a bonding machine for producing smart bracelets. This application adopts a design concept of integrating main body positioning, automated film bonding and cutting to bond the bracelet body. Compared with the existing film bonding method, this application only needs to place the bracelet body into the positioning frame to position and lock it with air suction. Then, the bonding module presses and bonds the long strip of film from the middle to both sides, thereby bonding the film to the screen. Under the state of the long strip of film being taut, the possibility of wrinkles and air bubbles is greatly reduced during the entire bonding process. Moreover, the long strip of film used in this application is bonded first and then cut, so there will be no misalignment.

[0022] 2. The bonding machine for smart bracelet production described in this invention adopts a structural linkage design concept for the bonding module. During the entire bonding process, the bonding component in the middle bonds the long strip of film to the middle of the screen. As the pressing rod descends and the power supply group supplies power, the electric slider drives the moving frame to move, so that the pressing component gradually unlocks and gradually presses the long strip of film on both sides of the bonding module outward. The entire bonding trajectory extends from the middle to both sides, which improves the fit of the film.

[0023] 3. The bonding machine for smart bracelet production described in this invention has a hinged connection between the angle plate and the movable seat, ensuring that the angle plate can change its angle under different environments (it can be raised to a horizontal state when applying film, and naturally hangs down when not applying film). The horizontal placement during film application ensures that the second flexible layer and the first flexible layer are on the same horizontal plane, thus enabling overall film application. When the angle plate is not in use, it hangs down naturally, avoiding contact between the cutting blade and the angle plate, greatly reducing wear between them (since the length formed between the horizontally placed angle plate and the movable seat is equal to the width of the cutting blade, the natural hanging of the angle plate prevents the angle plate from affecting the subsequent rise of the cutting blade). Furthermore, before the cutting blade rises, as the angle plate hangs down, the pressing component and the bonding component re-approach each other, making the structural volume formed between the middle frame, the bonding component, and the pressing component smaller, so as not to affect the rise of the cutting blade.

[0033] Embodiments of the present invention will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0034] Furthermore, the terms used below are defined based on the functionality of this invention and may vary depending on the user's, operator's, or conventions. Therefore, these terms are defined based on the entire contents of this specification.

[0035] like Figures 1 to 8 As shown, a bonding machine for producing smart bracelets includes a housing 1, a base 2 mounted on the bottom of the housing 1, a liftable cutting module 3 mounted on the base 2, a lifting plate 4 located inside the cutting module 3 connected to the base 2 by a lifting cylinder 5, a bonding module 6 mounted on the upper end of the lifting plate 4, a positioning module 7 mounted on the upper end of the housing 1, and tensioning modules 8 mounted on the left and right ends inside the housing 1. The bracelet body is placed into the positioning module 7 for positioning and air suction, with the screen of the bracelet body facing down. Then, the air-suction bracelet body is lowered to a suitable position, and bonding is achieved through a rising mechanism. Module 6 lifts the conveyed long roll of film (with the adhesive layer facing up) upwards for bonding (the bonding trajectory is from the middle to both sides). After bonding, the bonding module 6 descends and retracts back into its original position. Then, by the rising of the cutting module 3, the long roll of film is cut along the edge of the screen, thus obtaining a protective film that matches the screen. This protective film is then attached to the screen by the bonding module 6. The wristband body is embedded and positioned using air suction. Subsequently, the long roll of film is trimmed using automated film bonding and trimming. Compared to manual film bonding, this is more conducive to automated production lines.

[0036] The bonding module 6 includes a middle frame 61, a bonding component 62, a pressing rod 63, a power supply group 64, an electric slider 65, a moving frame 66, and a pressing component 67. The middle frame 61 is mounted on the lifting plate 4. The upper end of the middle frame 61 is provided with a bonding component 62 that can be elastically lifted and lowered. The lower end of the bonding component 62 is provided with a pressing rod 63. The power supply group 64 is symmetrically installed on the left and right ends of the middle frame 61. The power supply group 64 is electrically connected to the electric slider 65 provided on the lifting plate 4. The power supply group 64 and the pressing rod 63 are pressed together. When the pressing rod 63 has not descended to the lowest position, the power supply group 64 is in a disconnected state. The electric slider 65 is provided with a moving frame 66. The upper end of the moving frame 66 is provided with a pressing component 67 that can be extended and retracted. The pressing component 67 is pressed together with the middle frame 61.

[0037] The pressing assembly 67 includes a fixed base 671, a reset telescopic rod 672, a movable base 673, a first flexible layer 674, a pressing unit 675, an ejection unit 676, an angle plate 677, and a second flexible layer 678. The fixed base 671 is mounted on the movable frame 66. A reset telescopic rod 672 connects the fixed base 671 and the movable base 673. The reset telescopic rod 672 always maintains an upward pushing tendency on the movable base 673. The upper end of the movable base 673 is covered with the first flexible layer 674. The pressing unit 675 is installed on the side wall of the movable base 673. The front and rear ends of the movable base 673 are hinged to the upper end of the angle plate 677. The outer side wall of the angle plate 677 is covered with the second flexible layer 678. 74. The flexible material of the second flexible layer 678 further improves the fit of the long strip film to the screen surface. An ejection unit 676 is provided between the fixed seat 671 and the movable seat 673. The ejection unit 676 controls the angle of the angle plate 677. When the ejection unit 676 extends, it lifts the hanging angle plate 677, thereby forming a horizontally placed angle plate 677. The angle plate 677 and the movable seat 673 are connected by a hinge, which ensures that the angle plate 677 can be pushed to a horizontal state when the film is applied, so that the second flexible layer 678 and the first flexible layer 674 are on the same horizontal plane. When the film is not applied, the angle plate 677 hangs down naturally, avoiding contact between the cutting module 3 and the angle plate 677, and greatly reducing wear between them.

[0038] The specific bonding method is as follows: the lifting cylinder 5 drives the lifting plate 4 to rise. During the rising process, the bonding component 62 will bond with the lower end of the long strip of film, thereby bonding the long strip of film to the screen. Then, under the pressure of the main body of the wristband, the bonding component 62 gradually approaches the middle frame 61 until the two are bonded. At this time, the synchronously moving pressing rod 63 connects the circuit in the power supply group 64. After the electric slider 65 is powered on, it drives the moving frame 66 and the pressing component 67 to move outward. During the outward movement, the movable seat 673 unlocks, and under the action of the push-out unit 676, the angle plate 677 unfolds back and forth, so that the first flexible layer 674 and the second flexible layer 678 are on the same horizontal plane. The unlocked movable seat 673 resets the telescopic rod 672 so that the first flexible layer 674 and the second flexible layer 678 on the same horizontal plane tightly bond the long strip of film to the screen surface of the main body of the wristband. The bonding of the film from the middle to both sides improves the flatness of the film and reduces the generation of bubbles and wrinkles.

[0039] In another embodiment of the present invention, the cutting module 3 further includes a connecting cylinder 31, a knife holder 32, and a cutting knife 33. The connecting cylinder 31 is installed inside the base 2, and the knife holder 32 is installed on the upper end of the connecting cylinder 31. The position between the knife holder 32 and the cutting knife 33 is temporarily locked. The cutting knife 33 with the corresponding structure is replaced for different specifications of the bracelet body.

[0040] Specifically, after the screen protector is applied, the connecting cylinder 31 drives the blade holder 32 and the cutting blade 33 to rise as a whole. The cutting blade 33 then cuts the long strip of film along the edge of the screen (the precise cutting of the cutting blade 33 will only cut the long strip of film, but will not touch or scratch the screen).

[0041] Furthermore, the positioning module 7 includes a positioning frame 71, a bottom positioning component 72, a bidirectional lead screw 73, a connecting seat 74, a motor 75, an L-shaped frame 76, a pneumatic positioning head 77, and a pushing cylinder 78. The positioning frame 71 is installed in the upper middle part of the outer casing 1. The bottom positioning component 72 is symmetrically slidably arranged at the left and right ends of the positioning frame 71. The connecting seat 74 is symmetrically installed at the front end of the positioning frame 71. The bidirectional lead screw 73 is connected between the connecting seats 74 through bearings. The bidirectional lead screw 73 and the bottom positioning component 75 are connected to the bottom positioning component 76. The two parts are connected by a threaded fit. The rotation of the double-acting screw 73 drives the bottom positioning part 72 to move in opposite directions or in the opposite direction. One end of the double-acting screw 73 is connected to the output shaft of the motor 75. The motor 75 is mounted on the outer wall of the positioning frame 71 through a motor mount. An L-shaped frame 76 is installed on the upper end of the positioning frame 71. A push cylinder 78 is connected between the L-shaped frame 76 and the air suction positioning head 77. The air suction positioning head 77 has a built-in air pump, which is used to suction the wristband body onto the lower surface of the air suction positioning head 77.

[0042] Specifically, by pushing the cylinder 78, the air suction positioning head 77 is raised to its highest position, providing space for the bracelet body to be placed. Then, the bracelet body is placed into the positioning frame 71. The position of the bracelet body is limited by the inner cavity of the positioning frame 71 and the lower limit of the bottom positioning part 72. Then, by pushing the cylinder 78, the air suction positioning head 77 is lowered until it fits against the upper surface of the bracelet body and is air-suction locked. Then, the motor 75 drives the bidirectional lead screw 73 to rotate, thereby driving the bottom positioning part 72 to move in the opposite direction until it is in a retracted and hidden state. At this time, there is no structure under the bracelet body to limit it, and the air suction positioning head 77 and the bracelet body held by it can be lowered by pushing the cylinder 78.

[0043] Furthermore, the tensioning module 8 includes an electric roller 81 and a sleeve 82. The electric roller 81 is installed on the inner side wall of the rear end of the outer casing 1. The sleeve 82 is sleeved on the electric roller 81. The sleeve 82 is slidably sleeved on the electric roller 81. A long strip of film is wound between the sleeves 82 arranged on the left and right.

[0044] Specifically, after the long strip of film is used up, the outer casing 1 is opened, the sleeve 82 is pulled forward, the roll with the long strip of film is placed on the sleeve 82, and then pushed back to reset. Then the free end of the new long strip of film is led out and attached to another sleeve 82. The long strip of film is conveyed in a tensioned manner by the synchronous rotation of the electric rollers 81 arranged on the left and right.

[0045] Furthermore, the bonding component 62 includes a connecting plate 621, an elastic telescopic rod 622, and a flexible layer 623. The connecting plate 621 is connected to the middle frame 61 by the elastic telescopic rod 622, which always pushes the connecting plate 621 upward. The upper end of the connecting plate 621 is covered with a flexible layer 623, and the flexible layer 623 is made of the same material as the flexible layer 678.

[0046] Furthermore, the power supply group 64 includes an insulating frame 641, a power supply 642, a fixed conductive component 643, a movable conductive component 644, an insulating rod 645, and a compression spring 646. The insulating frame 641 is mounted on the lifting plate 4. The power supply 642, the fixed conductive component 643, and the movable conductive component 644 inside the insulating frame 641 are electrically connected to the electric slider 65. The movable conductive component 644 is movably disposed within the insulating frame 641. An insulating rod 645 is installed at the inner end of the movable conductive component 644. A compression spring 646 is connected between the insulating rod 645 and the lifting plate 4. The compression spring 646 always maintains an upward pushing tendency on the insulating rod 645. The insulating rod 645 is always in contact with the pressing rod 63, and the movable conductive component 644 and the fixed conductive component 643 are initially separated.

[0047] Specifically, when the extrusion rod 63 descends to its lowest position, the movable conductive element 644 comes into contact with the fixed conductive element 643, so that a complete circuit is formed between the power supply 642, the fixed conductive element 643, the movable conductive element 644 and the electric slider 65. At this time, the electric slider 65 is energized and drives the moving frame 66 to move (the moving trajectory of the moving frame 66 is one reciprocating movement).

[0048] Furthermore, the movable frame 66 is symmetrically provided with sliders at both the front and rear ends. The sliders are slidably mounted on the slide rail 68, which is installed on the edge of the lifting plate 4. The sliders and the slide rail 68 cooperate to provide auxiliary support for the sliding of the two sides of the movable frame 66.

[0049] Furthermore, the extrusion unit 675 includes an extrusion plate 6751 and an extrusion roller 6752. One end of the extrusion plate 6751 is mounted on the movable seat 673, and the other end of the extrusion plate 6751 is provided with a rotatable extrusion roller 6752. Extrusion grooves are symmetrically opened at the left and right ends of the middle frame 61. The extrusion grooves and the extrusion roller 6752 are in extrusion contact. The inclined surface of the extrusion grooves gradually slopes downward from the outside to the inside. The opening of the extrusion grooves is mainly to cooperate with the extrusion unit 675, so as to lock the height of the movable seat 673 when it is not in use.

[0050] Furthermore, the ejection unit 676 includes a pusher frame 6761, a connecting roller 6762, and an extrusion block 6763. The pusher frame 6761 is slidably mounted on the movable seat 673. The lower end of the pusher frame 6761 is provided with a rotatable connecting roller 6762. The connecting roller 6762 contacts the outer surface of the extrusion block 6763. The extrusion block 6763 is mounted on the fixed seat 671. The middle part of the outer surface of the extrusion block 6763 has a structure that gradually slopes inward from top to bottom, which reduces the difficulty of extrusion between it and the connecting roller 6762.

[0051] Specifically, the electric slider 65 drives the movable frame 66 to move outward. During the movement, under the action of the reset telescopic rod 672, the extrusion plate 6751 gradually rises along the inclined surface of the extrusion groove until the extrusion plate 6751 disengages from the extrusion groove and unlocks. At this time, under the action of the reset telescopic rod 672, the flexible layer 678 adheres the long strip film to the screen surface. The electric slider 65 drives the movable frame 66 to move to the outermost side and then moves in the opposite direction, thus moving inward. Subsequently, under the action of the extrusion groove, the height of the movable seat 673 is locked. After the height of the movable seat 673 is unlocked, the movable seat 673 drives the pusher 6761 to move upward. Under the pressure of the outer side of the extrusion block 6763, the pusher 6761 extends out of the movable seat 673, thereby pressing the lower end of the angle plate 677, so that the angle plate 677 is placed horizontally.

[0052] Furthermore, the angle plate 677 and the side wall of the fixed seat 671 are magnetically attracted. The magnetic attraction has a certain attraction force, but they can be separated when the squeezing force is greater than the attraction force. Under the forced squeezing of the push frame 6761, the angle plate 677 separates from the side wall of the fixed seat 671 and is then placed horizontally. When the push frame 6761 retracts, the angle plate 677 falls naturally under the action of gravity and is then attracted to the side wall of the fixed seat 671 under the magnetic attraction force.

[0053] Work process:

[0054] The main body of the bracelet is placed into the positioning module 7 for positioning and air suction locking, with the screen of the main body of the bracelet facing down;

[0055] The lifting cylinder 5 drives the lifting plate 4 to rise. During the rising process, the bonding component 62 will bond with the lower end of the long strip of film, thereby bonding the long strip of film to the middle of the screen. Then, under the pressure of the main body of the bracelet, the bonding component 62 gradually approaches the middle frame 61 until the two are bonded. At this time, the synchronously moving pressing rod 63 connects the circuit in the power supply group 64. After the electric slider 65 is powered on, it drives the moving frame 66 and the pressing component 67 to move outward. During the outward movement, the movable seat 673 is unlocked, and under the action of the push-out unit 676, the angle plate 677 unfolds back and forth, so that the first flexible layer 674 and the second flexible layer 678 are on the same horizontal plane. The unlocked movable seat 673 resets the telescopic rod 672 so that the first flexible layer 674 and the second flexible layer 678 on the same horizontal plane tightly bond the long strip of film to the screen surface of the main body of the bracelet, thereby gradually sliding the long strip of film from the middle of the screen to both sides.

[0056] After bonding, the bonding module 6 descends and retracts back into its original position (the bonding component 62 and the pressing component 67 move closer together again, and the angle plate 677 hangs down naturally). Then, the cutting blade 33 rises to cut the long strip of film along the edge of the screen, thereby obtaining a protective film that matches the screen, thus completing the film application.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
