Description

Technical Field

[0001] This invention relates to the field of electronic product manufacturing technology, and in particular to a barcode scanning device. Background Technology

[0002] A QR code is a black-and-white graphic symbol used to record data information, arranged in a specific geometric pattern on a two-dimensional plane. It has a certain verification function. During the production of laptops, a corresponding QR code is laser-engraved on the casing of each laptop. After scanning the QR code on the laptop casing, a scanning device can obtain the information it contains, enabling the traceability of each laptop.

[0003] After the laptops are assembled, they are scanned to input their information into the production system and / or the customer's system. In existing technology, the common procedure is for operators to remove the laptops one by one from the conveyor line and transfer them to the scanning station. After the scanning device completes the scan, the operator then transfers them back to the conveyor line. This method results in a large workload for operators, low scanning efficiency, and high labor costs.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0051] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0054] Figure 1 A schematic diagram of the scanning device provided in an embodiment of the present invention is shown. Figure 2 It shows Figure 1 A magnified view of a portion at point A. (See attached image.) Figures 1-2 As shown, this embodiment provides a barcode scanning device, which includes a transmission mechanism 1, a first positioning mechanism 2, a first blocking mechanism 3, and a scanning mechanism 4. The transmission mechanism 1 is used to receive the workpiece 100 from the previous process and can transmit the workpiece 100. The first positioning mechanism 2 is disposed on the transmission support 11 of the transmission mechanism 1 and is configured to position the workpiece 100. The first blocking mechanism 3 is disposed on the transmission support 11 and has at least a first blocking position to block the transmission of the workpiece 100 and a first clearance position to allow the workpiece 100 to be transmitted. The scanning mechanism 4 is disposed on the transmission support 11. When the first blocking mechanism 3 is located at the first blocking position, the scanning mechanism 4 can scan the QR code information on the workpiece 100 blocked by the first blocking mechanism 3.

[0055] The barcode scanning device provided in this embodiment, by setting a transmission mechanism 1, can drive the workpiece 100 to transfer between various mechanisms; by setting a first positioning mechanism 2, it can realize the positioning operation of the workpiece 100, so that the barcode scanning mechanism 4 can accurately scan the QR code on the workpiece 100; by setting a first blocking mechanism 3, after the workpiece 100 is positioned, the first blocking mechanism 3 can change from a first clearance position to a first blocking position to prevent the workpiece 100 from continuing to be transmitted forward, thereby facilitating the barcode scanning operation of the barcode scanning mechanism 4 and ensuring the accuracy of the barcode scanning result. After the barcode scanning operation is completed, the first blocking mechanism 3 can change from the first blocking position to a first clearance position to allow the workpiece 100 to continue to be transmitted. Through the cooperation between the transmission mechanism 1, the first positioning mechanism 2, the first blocking mechanism 3 and the barcode scanning mechanism 4, the barcode scanning operation of the workpiece 100 can be automated, saving manpower, improving barcode scanning efficiency and reducing labor costs.

[0056] It should be noted that, in this embodiment, the workpiece 100 placed on the transmission mechanism 1 includes a workpiece body 101 and a packaging box 102. The packaging box 102 is a box structure with an upper opening. A QR code is provided on the workpiece body 101, with the side of the workpiece body 101 having the QR code facing the upper opening of the packaging box 102, to facilitate the scanning operation of the scanning mechanism 4. This arrangement can prevent the workpiece body 101 from colliding with other mechanisms during transmission and causing damage.

[0057] In this embodiment, the workpiece body 101 specifically refers to the casing of a laptop computer, on which a QR code is laser-engraved. Of course, in other embodiments, the workpiece body 101 can also be other electronic products with QR codes on their surfaces. Optionally, the QR code can also be affixed to the surface of the workpiece body 101.

[0058] Before scanning the workpiece body 101, the operator will manually inspect its surface to ensure it meets requirements and avoids any oil stains or scratches. After the manual inspection, the operator will place the inspected workpiece body 101 into the packaging box 102, and then place the packaging box 102 containing the workpiece body 101 onto the transfer mechanism 1. It is understood that since the workpiece 100 on the transfer mechanism 1 is positioned by the first positioning mechanism 2, the operator does not need to align the workpiece 100 when placing it on the transfer mechanism 1, thus improving operator efficiency.

[0059] Optionally, the packaging box 102 is a foam box, which is lightweight and provides good cushioning. Of course, in other embodiments, the packaging box 102 can also be a corrugated cardboard box.

[0060] Furthermore, the transmission mechanism 1 can be a belt transmission mechanism, a chain transmission mechanism, or a roller transmission mechanism, and other devices capable of achieving the transmission effect are all within the protection scope of this embodiment. Since belt transmission mechanisms, chain transmission mechanisms, or roller transmission mechanisms are all existing technologies, the specific structure of the transmission mechanism 1 will not be described in detail in this embodiment. In addition, the transmission mechanism 1 can also transmit the workpiece 100 that has completed the scanning operation to the next process, serving two purposes in one, which can improve the compactness of the scanning device structure and reduce production costs.

[0061] Figure 3 A schematic diagram of the structure of the first positioning component 21 and the first positioning drive component 22 provided in an embodiment of the present invention is shown. Figure 3 Combination Figure 2As shown, the first positioning mechanism 2 includes two first positioning components 21, which are disposed opposite to each other on the transmission support 11, and the line connecting them is perpendicular to the transmission direction of the transmission mechanism 1. At least one of the two first positioning components 21 is movable. When the workpiece 100 is transmitted to the positioning area of ​​the first positioning mechanism 2 via the transmission mechanism 1, the movable first positioning component 21 moves toward the other first positioning component 21 to clamp the workpiece 100 between the two first positioning components 21, thereby achieving precise positioning of the workpiece 100.

[0062] In this embodiment, one of the two first positioning components 21 is a fixed positioning component, and the other is a movable positioning component. The fixed positioning component is fixedly mounted on the transfer bracket 11 to provide a positioning reference for the workpiece 100; the movable positioning component is movably mounted on the transfer bracket 11 and can move towards the fixed positioning component to push the workpiece 100 to a position where it abuts against the fixed positioning component. Of course, in other embodiments, both first positioning components 21 can be movable positioning components, and the above effect can also be achieved.

[0063] Optionally, the first positioning mechanism 2 further includes a first positioning drive component 22, the output end of which is connected to the movable positioning component. The first positioning drive component 22 is a positioning drive cylinder.

[0064] Furthermore, the first positioning component 21 includes a positioning connecting plate 211 and a plurality of positioning wear-reducing components 212. The plurality of positioning wear-reducing components 212 are spaced apart and rotatably disposed on the positioning connecting plate 211 along the transmission direction of the transmission mechanism 1. With this arrangement, the sliding friction between the first positioning component 21 and the workpiece 100 can be converted into rolling friction between the positioning wear-reducing components 212 and the workpiece 100, thereby reducing the wear between the first positioning component 21 and the workpiece 100 and improving the smoothness of the transmission of the workpiece 100 between the two first positioning components 21, thereby achieving precise positioning during the transmission of the workpiece 100.

[0065] Optionally, in this embodiment, the positioning and wear-reducing component 212 is a bearing, and the positioning connecting plate 211 is a bearing housing. The positioning and wear-reducing component 212 is fixed to the positioning connecting plate 211 by a stepped pin. Of course, in other embodiments, the positioning and wear-reducing component 212 can also be other wheel-shaped structures.

[0066] Furthermore, an L-shaped fixing plate 23 is provided between the first positioning drive component 22 and the first positioning component 21. The horizontal plate of the L-shaped fixing plate 23 contacts the bottom surface of the first positioning component 21, and the vertical plate of the L-shaped fixing plate 23 is connected to the output end of the first positioning drive component 22. By providing the L-shaped fixing plate 23, the first positioning component 21 can be supported, ensuring a more stable connection between it and the first positioning drive component 22.

[0067] Figure 4 A partial structural schematic diagram of the first material-stopping mechanism 3 provided in an embodiment of the present invention is shown. For example... Figure 4 Combination Figure 2 As shown, the first material blocking mechanism 3 includes a first material blocking bracket 31, a material blocking lifting drive 32, and a material blocking part 33. The first material blocking bracket 31 is disposed on the transmission bracket 11; the material blocking lifting drive 32 is disposed on the first material blocking bracket 31; the material blocking part 33 is connected to the output end of the material blocking lifting drive 32 and can move vertically under the driving action of the material blocking lifting drive 32, so as to move between the first material blocking position and the first clearance position.

[0068] Specifically, the stop section 33 includes a stop connector 331 and a stop wear-reducing component 332. The stop connector 331 is connected to the output end of the stop lifting drive section 32. At least two stop wear-reducing components 332 are spaced apart and rotatably mounted on the stop connector 331 in a direction perpendicular to the transmission direction of the transmission mechanism 1. This arrangement reduces wear between the workpiece 100 and the stop section 33, ensuring the appearance quality of the workpiece 100.

[0069] Optionally, in this embodiment, the material-stopping and wear-reducing component 332 is a bearing, and the material-stopping connector 331 is a bearing housing. The material-stopping and wear-reducing component 332 is fixed to the material-stopping connector 331 by a stepped pin. Of course, in other embodiments, the material-stopping and wear-reducing component 332 can also be other wheel-shaped structures.

[0070] Furthermore, such as Figure 2 As shown, the first material-stopping bracket 31 includes a material-stopping gate-shaped plate and a material-stopping base plate. The material-stopping gate-shaped plate spans across both sides of the transmission bracket 11, and a material-stopping base plate is connected to both ends of the material-stopping gate-shaped plate near the transmission bracket 11. The material-stopping base plate is bolted to the transmission bracket 11. The material-stopping base plate increases the contact area between the first material-stopping bracket 31 and the transmission bracket 11, improving the connection stability between the first material-stopping bracket 31 and the transmission bracket 11. Optionally, the first material-stopping bracket 31 also includes material-stopping reinforcing ribs. Each material-stopping base plate and the material-stopping gate-shaped plate is provided with a material-stopping reinforcing rib to improve the strength of the first material-stopping bracket 31 and ensure the connection stability between the first material-stopping bracket 31 and the transmission bracket 11.

[0071] It should be noted that in this embodiment, each workpiece 100 needs to be scanned twice. The scanning mechanism 4 transmits one scan result to the production system and the other scan result to the customer system. Therefore, the scanning mechanism 4 includes a first scanning component 41 and a second scanning component 42. The first scanning component 41 is communicatively connected to the first control system and can scan the QR code information on the workpiece 100 and transmit it to the first control system. The second scanning component 42 is communicatively connected to the second control system and can scan the QR code information on the workpiece 100 and transmit it to the second control system. One of the first control system and the second control system is the production system, and the other is the customer system.

[0072] Correspondingly, there are two first blocking mechanisms 3, corresponding to the first scanning component 41 and the second scanning component 42 respectively. The first blocking mechanism 3 corresponding to the first scanning component 41 can block the workpiece 100 in the scanning area of ​​the first scanning component 41 to facilitate the first scanning operation; the first blocking mechanism 3 corresponding to the second scanning component 42 can block the workpiece 100 in the scanning area of ​​the second scanning component 42 to facilitate the second scanning operation.

[0073] To improve scanning accuracy, the scanning device also includes a first detection mechanism 7 and a second detection mechanism 9. When the first detection mechanism 7 detects the workpiece 100, both first blocking mechanisms 3 move from the first clearance position to the first blocking position to prepare for blocking. When the second detection mechanism 9 detects the workpiece 100, the first positioning mechanism 2 positions the workpiece 100. Furthermore, the first scanning component 41 is located between the first detection mechanism 7 and the second detection mechanism 9. When the upstream first blocking mechanism 3 blocks the workpiece 100, and the workpiece 100 has completed its second positioning, the first scanning component 41 can scan the workpiece 100. After the first scanning component 41 completes scanning, the upstream first blocking mechanism 3 moves from the first blocking position to the first clearance position, allowing the workpiece 100 to be transferred to the scanning area of ​​the second scanning component 42. After the second scanning component 42 completes scanning, the downstream first blocking mechanism 3 moves from the first blocking position to the first clearance position, allowing the workpiece 100 to continue to be transferred to the next process.

[0074] Specifically, each first detection mechanism 7 includes a detection bracket 71 and a detection element 72 disposed on the detection bracket 71. The detection bracket 71 is connected to the transmission bracket 11. The detection element 72 is a proximity switch. When the workpiece 100 is transmitted to the detection area of ​​the detection element 72, the detection element 72 can transmit the signal to the controller of the barcode scanning device. The controller controls the corresponding first blocking mechanism 3 to move from the first clearance position to the first blocking position.

[0075] Optionally, the detection bracket 71 has a Z-shaped cross-section, which not only ensures the stability of the connection between the first detection mechanism 7 and the transmission bracket 11, but also saves materials and reduces manufacturing costs. Optionally, the detection bracket 71 is fixed to the transmission bracket 11 by bolts.

[0076] It should be noted that the specific structure of the second detection mechanism 9 is the same as that of the first detection mechanism 7. This embodiment will not describe the specific structure of the second detection mechanism 9 in detail.

[0077] Figure 5 A schematic diagram of the structure of the first barcode scanning component 41 provided in an embodiment of the present invention is shown. Figure 5 Combination Figure 2 As shown, the first scanning component 41 includes a scanning bracket 411 and a barcode scanner 412 mounted on the scanning bracket 411. The scanning bracket 411 is mounted on the transmission bracket 11. The barcode scanner 412 can scan the QR code on the workpiece 100 and transmit the scanning result to the first control system or the second control system. This embodiment does not limit the specific structure of the barcode scanner 412; any barcode scanner 412 that can perform scanning functions in the prior art is within the protection scope of this embodiment.

[0078] Furthermore, the barcode scanner bracket 411 includes a barcode support frame 4111 and a barcode connecting frame 4112. The barcode support frame 4111 has an L-shaped cross-section. The horizontal plate of the barcode support frame 4111 is fixed to the transmission bracket 11, and the barcode connecting frame 4112 is connected to the vertical plate of the barcode support frame 4111. The barcode scanner 412 is mounted on the barcode connecting frame 4112. By setting the barcode support frame 4111 to an L-shape, the contact area between the barcode scanner bracket 411 and the transmission bracket 11 can be increased, thereby improving the stability of the barcode scanner bracket 411.

[0079] Optionally, a first reinforcing rib 4113 is provided between the horizontal plate and the vertical plate of the barcode scanning support frame 4111 to improve the strength of the barcode scanning support frame 4111 and further ensure its stability. A second reinforcing rib 4114 is provided between the vertical plate of the barcode scanning support frame 4111 and the barcode connecting frame 4112 to improve the strength of the barcode scanning support frame 4111 and further ensure its stability.

[0080] It should be noted that in this embodiment, the specific structure of the second scanning component 42 is the same as that of the first scanning component 41, the only difference being the setting position. The specific structure of the second scanning component 42 will not be described in detail in this embodiment.

[0081] To improve the accuracy of scanning results, such as Figure 2As shown, the scanning device also includes a second positioning mechanism 5, which is mounted on the transmission support 11 and located upstream of the first positioning mechanism 2. The second positioning mechanism 5 is configured to perform preliminary positioning of the workpiece 100. After manual inspection, the operator randomly places the workpiece 100 on the transmission mechanism 1. At this time, the deviation between the workpiece 100 and the precise position is relatively large. By setting up the second positioning mechanism 5, which cooperates with the first positioning mechanism 2, the workpiece 100 can be positioned twice, thereby ensuring the accuracy of the workpiece 100's position and thus ensuring the accuracy of the scanning result of the scanning mechanism 4.

[0082] Furthermore, the second positioning mechanism 5 includes two second positioning components 51, which are disposed opposite to each other on the transmission support 11, and the line connecting them is perpendicular to the transmission direction of the transmission mechanism 1. At least one of the two second positioning components 51 is movably positioned. When the workpiece 100 is transmitted to the positioning area of ​​the second positioning mechanism 5 via the transmission mechanism 1, the movably positioned second positioning component 51 moves toward the other second positioning component 51 to clamp the workpiece 100 between the two second positioning components 51, thereby achieving precise positioning of the workpiece 100.

[0083] In this embodiment, both second positioning components 51 are movable positioning components. Optionally, the second positioning mechanism 5 further includes a second positioning drive component 52, with each second positioning component 51 corresponding to a second positioning drive component 52. The second positioning drive component 52 can drive the corresponding second positioning component 51 to move towards the workpiece 100, thereby achieving preliminary positioning of the workpiece 100. The second positioning drive component 52 is a positioning drive cylinder. Of course, in other embodiments, one of the two first positioning components 21 is a fixed positioning component, and the other is a movable positioning component, which can also achieve the above effect.

[0084] It should be noted that the specific structure of the second positioning component 51 is the same as that of the first positioning component 21, the difference being the different setting positions. In this embodiment, the specific structure of the second positioning component 51 will not be described in detail.

[0085] In this embodiment, when the first positioning component 21 and the second positioning component 51, located on the same side, extend to position the workpiece 100, the contact positions of the first positioning component 21 and the workpiece 100 are staggered. This method improves the fault tolerance rate; even if a positional shift occurs during the transfer of the workpiece 100 from the second positioning mechanism 5 to the first positioning mechanism 2, it will not affect the accuracy of the scanning result.

[0086] It should be noted that, in this embodiment, the number of positioning and wear-reducing elements 212 in the second positioning component 51 is less than the number of positioning and wear-reducing elements 212 in the first positioning component 21. This arrangement allows the workpiece 100 to be smoothly transferred from the positioning area of ​​the second positioning mechanism 5 to the positioning area of ​​the first positioning mechanism 2. Of course, in other embodiments, the number of positioning and wear-reducing elements 212 in the second positioning component 51 and the number of positioning and wear-reducing elements 212 in the first positioning component 21 may be the same, or the number of positioning and wear-reducing elements 212 in the second positioning component 51 may be greater than the number of positioning and wear-reducing elements 212 in the first positioning component 21.

[0087] Furthermore, the scanning device also includes a second blocking mechanism 6, which is mounted on the transmission support 11 and located upstream of the first positioning mechanism 2. The second blocking mechanism 6 has at least a second blocking position to block the transmission of the workpiece 100 and a second clearance position to allow the workpiece 100 to be transmitted. The second blocking mechanism 6 can block the workpiece 100 within the positioning area of ​​the second positioning mechanism 5. After the scanning mechanism 4 has completed the scanning operation on the workpiece 100 located downstream of the transmission mechanism 1, it moves from the second blocking position to the second clearance position, thereby avoiding the phenomenon of multiple workpieces 100 simultaneously entering the scanning area of ​​the scanning mechanism 4, which would lead to incorrect scanning results.

[0088] Figure 6 A schematic diagram of the structure of the second material-stopping mechanism 6 provided in an embodiment of the present invention is shown. Figure 6 and combined Figure 2 As shown, the second material blocking mechanism 6 includes a second material blocking bracket 61, a material blocking rotation drive unit 62, and a material blocking plate 63. The second material blocking bracket 61 is mounted on the transmission bracket 11. The material blocking rotation drive unit 62 is mounted on the second material blocking bracket 61. One end of the material blocking plate 63 is rotatably mounted on the second material blocking bracket 61, and the other end of the material blocking plate 63 is connected to the output end of the material blocking rotation drive unit 62. When the material blocking rotation drive unit 62 drives the material blocking plate 63 to rotate until the length direction of the material blocking plate 63 is parallel to the vertical direction, the material blocking plate 63 is located in the second material blocking position. When the material blocking rotation drive unit 62 drives the material blocking plate 63 to rotate until the length direction of the material blocking plate 63 is parallel to the horizontal direction, the material blocking plate 63 is located in the second clearance position. Optionally, the material blocking rotation drive unit 62 is a rotary cylinder.

[0089] Specifically, the second baffle bracket 61 includes two baffle support plates, which are located on both sides of the transmission bracket 11, and the baffle rotation drive unit 62 is disposed on one of the baffle support plates. The baffle support plate has an L-shaped cross-section to increase the contact area between the second baffle bracket 61 and the transmission bracket 11 and improve the stability of their connection.

[0090] Furthermore, one end of the baffle plate 63 is rotatably connected to the baffle support plate via a bearing; the other end of the baffle plate 63 is connected to the baffle rotation drive unit 62 via a flange, thereby improving the stability of the connection between the baffle plate 63 and the second baffle bracket 61 and between the baffle plate 63 and the baffle rotation drive unit 62, and ensuring the stability of its rotation process.

[0091] Continue to refer to Figure 2 The scanning device also includes a third detection mechanism 8, which corresponds to the second positioning mechanism 5. The second positioning mechanism 5 is configured such that when the third detection mechanism 8 detects the workpiece 100, the second positioning drive component 52 can drive the corresponding second positioning component 51 to extend so as to position the workpiece 100.

[0092] It should be noted that the specific structure of the third testing mechanism 8 is the same as that of the first testing mechanism 7, the only difference being the different placement. In this embodiment, the specific structure of the third testing mechanism 8 will not be described in detail.

[0093] The following is combined Figures 1-6 Briefly describe the working process of the barcode scanning device. In the initial state, both the first positioning component 21 and the second positioning component 51 are in the retracted state, both first blocking mechanisms 3 are in the first clearance position, and the second blocking mechanism 6 is in the second blocking position.

[0094] (1) After the operator manually inspects the workpiece 100, the qualified workpiece 100 is placed on the transmission mechanism 1, and the transmission mechanism 1 transmits the workpiece 100.

[0095] (2) After the third detection mechanism 8 detects the workpiece 100, the second positioning drive component 52 drives the corresponding second positioning component 51 to move towards the workpiece 100 so as to achieve the initial positioning of the workpiece 100.

[0096] (3) When there is no workpiece 100 to be scanned or being scanned at the scanning mechanism 4, the second blocking mechanism 6 moves from the second blocking position to the second clearance position, and at the same time the two second positioning components 51 retract, so that the workpiece 100 that has completed the initial positioning can continue to be transmitted.

[0097] (4) When the first detection mechanism 7 detects the workpiece 100, both first blocking mechanisms 3 move from the first clearance position to the first blocking position. When the second detection mechanism 9 detects the workpiece 100, the first positioning mechanism 2 positions the workpiece 100.

[0098] (5) The first scanning component 41 scans the workpiece 100 and transmits the scanning result to the first control system. After the first scanning component 41 completes the scanning, the first material blocking mechanism 3 located upstream moves from the first material blocking position to the first clearance position so that the workpiece 100 can continue to be transmitted.

[0099] (6) When the workpiece 100 is transferred to the point where it comes into contact with the first blocking mechanism 3 located downstream, the second scanning component 42 scans the workpiece 100 and transmits the scanning result to the second control system. After the second scanning component 42 completes the scanning, the first blocking mechanism 3 located downstream moves from the first blocking position to the first clearance position so that the workpiece 100 can continue to be transferred to the next process.

[0100] It should be noted that in step (2), the stroke of the second positioning component 51, which is located on the same side as the fixed first positioning component 21, is 100mm, and the stroke of the other second positioning component 51 is 150mm. When the barcode scanning device is running normally, the interval between steps (2) and (3) is usually 1s. That is, after the second positioning component 51 extends for 1s, the second blocking mechanism 6 moves from the second blocking position to the second clearance position, and at the same time, the two second positioning components 51 retract to match the production rhythm of other processes. In step (4), the stroke of the first blocking mechanism 3 from the first clearance position to the first blocking position is 20mm; the stroke of the movable first positioning component 21 is 150mm. It is understood that the above values ​​should not be used as a limitation of this embodiment. The stroke of the second positioning component 51, the stroke of the first blocking mechanism 3 from the first clearance position to the first blocking position, and the stroke of the movable first positioning component 21 can all be adjusted according to actual needs. This embodiment does not limit this.

[0101] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
