Description

Technical Field

[0001] This invention relates to the field of laser cutting, and more specifically, to a laser cutting apparatus. Background Technology

[0002] Laser cutting utilizes a high-energy-density laser beam focused on the material surface, rapidly removing material through mechanisms such as vaporization, melting, or oxidation. Simultaneously, auxiliary gases (such as oxygen or nitrogen) are used to blow away molten slag, achieving a high-precision, high-efficiency cutting process. Its advantages include non-contact processing, a small heat-affected zone, and the ability to cut complex shapes. It is widely used in planar or irregular-shaped cutting scenarios involving metals, non-metals, and composite materials. In the processing of metal tubes, laser cutting is often used to create holes at specific locations on the tube surface to meet the needs of subsequent processing and assembly.

[0003] Existing devices, such as the one disclosed in application number CN202210641761.X, include a laser drilling device for sheet metal round tubes. This device comprises: a worktable; the worktable has a rectangular cavity structure, and a receiving groove is located at the center of the top of the worktable, which is fixedly connected to the worktable by embedding; a discharge groove is located above the worktable, and the discharge groove is fixedly connected to the worktable by a support frame, which is located in front of the receiving groove, and a first motor is located on the right side of the support frame; an adjustment frame is located at the top of the worktable, and the adjustment frame is located behind the receiving groove. The adjustment frame has a rectangular frame structure, and a sliding frame is located between the frames of the adjustment frame. A clamping assembly is located at the front end of the sliding frame, and the clamping assembly is located above the receiving groove, and a third motor is located on the clamping assembly; a laser is located above the worktable, and the laser is fixedly connected to the worktable by a fixing frame, and the laser is located above the clamping assembly.

[0004] However, when processing tubes with varying hole positions and grouped together, such as 5 tubes with laser-drilled holes at position A, 4 tubes with laser-drilled holes at position B, and 6 tubes with laser-drilled holes at position C, totaling 15 tubes as a group, if the above method is used to complete the laser cutting, all the round tubes will fall freely into the feeding trough and then be collected in the same collection box. Therefore, manual grouping is required after processing. Thus, there is an urgent need for a laser cutting device that can meet the processing requirements of tubes with varying hole positions and grouped together. Summary of the Invention

[0005] Therefore, in order to solve the problem of not being able to meet the requirements of inconsistent opening positions and grouped collection, the present invention provides a laser cutting device, the specific technical solution of which is as follows:

[0006] A laser cutting device includes a worktable, a laser cutter, a clamping mechanism, a feeding mechanism, a distributing mechanism, a collection box assembly, and a conveyor belt. The laser cutter is vertically oriented and positioned directly above the worktable. The worktable is equipped with a first drive assembly for moving the laser cutter in the X and Z axis directions. The clamping mechanism is mounted on the worktable and is used to clamp metal tubes directly below the laser cutter. The feeding mechanism is mounted on the worktable and is used to transport metal tubes one by one to the clamping mechanism. A discharge trough is provided on the worktable corresponding to the position of the laser cutter, and the discharge trough extends obliquely out of one side of the worktable. The conveyor belt is located on the side of the worktable corresponding to the discharge trough, and a plurality of collection box assemblies are placed at intervals on the conveyor belt facing the conveying direction. The distributing mechanism is mounted on the worktable and corresponds to the discharge port of the discharge trough, and is used to guide the cut metal tubes into the collection boxes corresponding to the collection box assemblies.

[0007] By adopting the above technical solution, during processing, the metal tubes are first fed one by one to the clamping mechanism via the feeding mechanism. Then, the clamping mechanism holds the metal tubes directly below the laser cutting machine. Next, the first drive assembly is activated to move the laser cutting machine to the corresponding cutting position of the metal tube, and the laser cutting machine is started to complete the cutting. Then, the clamping mechanism releases the metal tubes, which fall into the unloading trough and roll to the discharge port under their own gravity. The cutting metal tubes are then guided into the corresponding collection box of the same collection box group by the sorting mechanism. After the metal tubes of the corresponding specifications have been collected in the same collection box group, the conveyor belt is started to transport the next collection box group to the discharge port position. This process can laser cut metal tubes at different positions and collect them in groups, greatly improving work efficiency.

[0008] Furthermore, the collection boxes in the same collection box group are arranged in the Y-axis direction, with the openings of the collection boxes facing upwards. Each collection box opening is rotatably mounted with a cover plate, and the pivot of the cover plate is located in the middle of the cover plate. The top of each collection box is inclined downwards from the discharge port position in a direction away from it. The material distribution mechanism includes a cover opening component, which is used to open the cover plate of the corresponding collection box in the same collection box group.

[0009] Furthermore, the collection box has abutment strips fixedly installed at both ends of the opening in the inclined direction, and the cover plate has a locking groove at both ends. The two locking grooves are respectively opened on both sides of the cover plate, and the locking groove near the discharge port is on the side of the cover plate facing downwards. The two abutment strips are respectively locked in the locking grooves, and the abutment strips are magnetically attracted to the bottom of the locking grooves.

[0010] Furthermore, the cover opening assembly includes a mounting box, a pair of driving blocks, and a first driving member. The mounting box has an opening at the bottom and is fixedly installed on the workbench corresponding to the discharge port. The two driving blocks are respectively installed on both sides inside the mounting box. One end of the driving block is slidably installed in the mounting box in an inclined direction toward the top of the collection box, and the other end of the driving block extends out of the opening of the mounting box. The first driving member is used to drive the driving block to move. Rubber rollers are fixedly installed at both ends of the rotating shaft of the cover plate. The top of the rubber rollers extends out of the top of the collection box, and the bottom surface of the driving block and the top surface of the rubber rollers are on the same plane.

[0011] Furthermore, the first driving component includes a lead screw and a servo motor. The lead screw is rotatably mounted in the mounting box, and the driving block is threaded onto the lead screw. The servo motor is fixedly mounted in the mounting box, and the output shaft of the servo motor is connected to the end of the lead screw.

[0012] Furthermore, the material distribution mechanism includes a buffer block and a feeding component. The buffer block is fixedly installed at the bottom of the discharge port of the feeding trough. The top of the buffer block is higher than the bottom of the discharge port of the feeding trough. The top surface of the buffer block is inclined and flush with the top of the collection box. The feeding component is used to lift the metal tube closest to the buffer block to the top surface of the buffer block.

[0013] Furthermore, the unloading component includes a lifting frame and a lifting cylinder. The lifting frame is slidably installed vertically on the worktable at the bottom of the discharge port corresponding to the unloading trough. The top of the lifting frame is an inclined surface parallel to the top surface of the buffer block. The bottom of the unloading trough has a clearance hole for the lifting frame to extend out. The lifting cylinder is fixedly installed inside the worktable, and the piston rod of the lifting cylinder is connected to the lifting frame.

[0014] Furthermore, the clamping mechanism includes a fixed clamping seat, a movable clamping seat, a pair of positioning rods, and a second drive assembly. The fixed clamping seat and the movable clamping seat are horizontally arranged opposite each other on the worktable. The movable clamping seat is slidably mounted on the worktable in a direction closer to or farther from the fixed clamping seat. The second drive assembly is used to drive the movable clamping seat to slide. The two positioning rods are respectively installed on opposite sides of the fixed clamping seat and the movable clamping seat, and the two positioning rods are respectively used to be inserted into both ends of the metal tube.

[0015] Furthermore, the feeding mechanism includes a feeding box, a sliding seat, a pair of clamping plates, a clamping cylinder, and an ejector. The feeding box is mounted on a workbench, and a horizontally extending discharge hole is provided on the bottom side wall of the feeding box for a single metal tube to pass through. The sliding seat is slidably mounted on the workbench in the Y-axis direction and located on one side of the feeding box. The workbench is equipped with a second driving member for driving the sliding seat to slide. The clamping cylinder is mounted on the sliding seat, and the two clamping plates are vertically opposite each other and respectively mounted on the clamping cylinder's gripper. The position between the two clamping plates corresponds to the discharge hole. The ejector is used to eject the metal tube corresponding to the position of the discharge hole to the position between the two clamping plates.

[0016] Furthermore, the feeding box includes a collecting chamber and a discharging chamber. The discharging chamber is located at one end of the bottom of the collecting chamber. The width of the discharging chamber is sufficient for a single metal tube to pass through. The bottom of the collecting chamber extends downwards towards the discharging chamber. The discharge hole is located at the very bottom of the discharging chamber. Attached Figure Description

[0032] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0033] like Figure 1 and Figure 2 As shown, a laser cutting device according to one embodiment of the present invention includes a worktable 1, a laser cutter 2, a clamping mechanism 3, a feeding mechanism 4, a dispensing mechanism 5, a collection box assembly 6, and a conveyor belt 7. The laser cutter 2 is vertically downward and directly above the worktable 1. The worktable 1 is equipped with a first driving assembly for driving the laser cutter 2 to move in the X-axis and Z-axis directions, wherein the X-axis direction is the length direction of the metal tube, and the Z-axis direction is the vertical direction. The clamping mechanism 3 is installed on the worktable 1 and is used to clamp the metal tube directly below the laser cutter 2. The feeding mechanism 4 is installed on the worktable 1. The workbench 1 is used to transport metal tubes one by one to the clamping mechanism 3; a feeding trough 13 is provided on the workbench 1 corresponding to the position of the laser cutting machine 2, and the feeding trough 13 extends obliquely out of one side of the workbench 1; a conveyor belt 7 is set on one side of the workbench 1 corresponding to the feeding trough 13, the conveyor belt 7 extends in the X-axis direction, and several collection box groups 6 are placed at intervals on the conveyor belt 7 in the conveying direction, and each collection box 61 in the collection box group 6 is arranged in the Y-axis direction; the material distribution mechanism 5 is installed on the workbench 1 at the outlet position corresponding to the feeding trough 13, and the material distribution mechanism 5 is used to guide the cut metal tubes into the collection box 61 corresponding to the collection box group 6.

[0034] During processing, the metal tubes are first fed one by one to the clamping mechanism 3 via the feeding mechanism 4. Then, the clamping mechanism 3 clamps the metal tubes directly below the laser cutting machine 2, and the laser cutting machine 2 completes the cutting. Next, the clamping mechanism 3 releases the metal tubes, and the metal tubes fall into the unloading trough 13. Then, the separating mechanism 5 guides the cut metal tubes into the corresponding collection box 61 of the same collection box group 6. After the metal tubes of the corresponding specifications are collected in the same collection box group 6, the conveyor belt 7 is started, and the conveyor belt 7 transports the next collection box group 6 to the discharge port position. This process can laser cut metal tubes at different positions and collect them in groups, which greatly improves work efficiency.

[0035] Specifically, such as Figure 2 , Figure 3 and Figure 4As shown, a support 14 is provided at the bottom of the feed inlet of the feed trough 13 on the workbench 1. A receiving groove 141 for metal tubes to fall into is opened directly above the support 14. The support 14 is located directly below the clamping position of the clamping mechanism 3. A driving cylinder 15 is installed inside the workbench 1. The cylinder body of the driving cylinder 15 is fixedly installed inside the workbench 1. The piston rod of the driving cylinder 15 extends and retracts vertically. The piston rod of the driving cylinder 15 is fixedly installed at the bottom of the support 14. Air nozzles 16 and dust hoods 17 are fixedly installed on the opposite side walls of the receiving groove 141 corresponding to the feed inlet position. The air nozzles 16 and dust hoods 17 are arranged horizontally opposite each other. The air nozzles 16 and dust hoods 17 are located on the moving path of the support 14. When the support 14 moves... When the tube is positioned between the air nozzle 16 and the dust hood 17, the air nozzle 16 and the dust hood 17 correspond to the two ends of the metal tube, respectively. The air nozzle 16 is connected to a blower (not shown in the figure), and the dust hood 17 is connected to an exhaust fan (not shown in the figure). Therefore, after the laser cutting is completed, the support 14 moves to a position directly below the clamping position, the clamping mechanism 3 releases the metal tube, and the metal tube falls into the receiving groove 141. Then, the driving cylinder 15 is activated to drive the support 14 to move vertically downward until the two ends of the metal tube are directly facing the air nozzle 16 and the dust hood 17, respectively. The air nozzle 16 is activated to blow away the cutting debris inside the metal tube and extract it through the dust hood 17, reducing the amount of cutting debris entering the collection box 61, thus facilitating subsequent processing.

[0036] Furthermore, a pusher plate 151 is provided on the top of the cylinder body of the driving cylinder 15. The top of the pusher plate 151 is an inclined surface parallel to the inclination direction of the feeding groove 13. The support 14 is provided with a through hole 142 for the pusher plate 151 to pass through at the position corresponding to the pusher plate 151. Therefore, when the driving cylinder 15 drives the support 14 to move to the bottom of the feeding groove 13, the metal tube in the receiving groove 141 is pushed away and rolled into the feeding groove 13 by the action of the pusher plate 151. This process not only allows the metal tube to enter the feeding groove 13 smoothly through the support 14, but also eliminates the need for an additional power source to push the metal tube away from the support 14, thus improving the linkage.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, the collection box 61 has an upward-facing opening, and each collection box 61 has a cover plate 62 rotatably mounted on its opening. The rotation axis of the cover plate 62 extends in the X-axis direction, and the rotation axis of the cover plate 62 is located in the middle of the cover plate 62. The top of each collection box 61 is inclined downwards from the discharge port position in a direction away from it, that is, when the cover plate 62 is in the covered state, the cover plate 62 is also in an inclined state. The material distribution mechanism 5 includes a cover opening component 51, which is used to open the cover plate 62 of the corresponding collection box 61 in the same collection box group 6. Therefore, according to the laser cutting position, the cover plate 62 on the collection box 61 used to collect this type can be opened, so that the metal tube can smoothly roll into the corresponding collection box 61.

[0038] At the opening of the collection box 61, abutment strips 611 are fixedly installed at both ends in the inclined direction. At both ends of the cover plate 62, there are locking grooves 621. The two locking grooves 621 are respectively opened on both sides of the cover plate 62, and the locking groove 621 near the discharge port is on the downward side of the cover plate 62. The two abutment strips 611 are respectively locked in the locking grooves 621. The abutment strips 611 and the bottom of the locking grooves 621 are magnetically attracted to each other by magnets, and the magnetic attraction force of the magnets is greater than the weight of the metal tube on the cover plate 62. Therefore, when the cover plate 62 is not opened, the metal tube can roll smoothly on the cover plate 62.

[0039] like Figure 2 and Figure 6 As shown, the cover opening assembly 51 includes a mounting box 511, a pair of driving blocks 512, and a first driving member. The mounting box 511 has an opening at the bottom and is fixedly installed at the corresponding discharge port of the workbench 1. The two driving blocks 512 are respectively installed on both sides inside the mounting box 511. One end of the driving block 512 is slidably installed on the inner wall of the mounting box 511 in an inclined direction toward the top of the collection box 61, and the other end of the driving block 512 extends out of the opening of the mounting box 511. The first driving member is used to drive the driving blocks 512 to move. Rubber rollers 622 are fixedly installed at both ends of the rotating shaft of the cover plate 62. The top of the rubber rollers 622 extends out of the top of the collection box 61. The driving blocks 512... The bottom surface and the top surface of the rubber roller 622 are on the same plane; therefore, the driving block 512 can be moved by activating the first driving member. When it moves to the position of the rubber roller 622 corresponding to the collection box 61, the cover plate 62 is driven to open by the friction between the driving block 512 and the rubber roller 622. At this time, the driving block 512 stays in the state of abutting against the rubber roller 622, so that the cover plate 62 is in the tilted open state, so that the metal tube can smoothly enter the corresponding collection box 61. When the driving block 512 leaves the position of the rubber roller 622, it can be rotated and reset by its own gravity, and the cover plate 62 covers the opening of the collection box 61 by magnetic attraction.

[0040] Furthermore, the first driving component includes a lead screw 513 and a servo motor 514. The lead screw 513 is rotatably mounted in the mounting box 511, and the driving block 512 is threaded onto the lead screw 513. The servo motor 514 is fixedly mounted in the mounting box 511, and the output shaft of the servo motor 514 is connected to the end of the lead screw 513. Thus, the driving block 512 can be stably driven to move by starting the servo motor 514.

[0041] Furthermore, such as Figure 2 and Figure 6As shown, the material distribution mechanism 5 includes a buffer block 52 and a feeding component. The buffer block 52 is fixedly installed at the bottom of the discharge port of the feeding trough 13. The top of the buffer block 52 is higher than the bottom of the discharge port of the feeding trough 13. The top surface of the buffer block 52 is inclined and flush with the top of the collection box 61. The feeding component is used to lift the metal pipe closest to the buffer block 52 to the top surface of the buffer block 52. The feeding component includes a lifting frame 53 and a lifting cylinder 54. The lifting frame 53 is slidably installed vertically on the workpiece. At the bottom of the discharge port of the feeding trough 13, the top of the lifting frame 53 is an inclined surface parallel to the top surface of the buffer block 52. The bottom of the feeding trough 13 is provided with a clearance hole 131 for the lifting frame 53 to extend. The lifting cylinder 54 is fixedly installed in the workbench 1, and the piston rod of the lifting cylinder 54 is connected to the lifting frame 53. Thus, metal pipes can be fed into the collection box group 6 one by one, reducing the impact force. It can also play a waiting role when the switching cover 62 is opened, without stopping the laser cutting operation.

[0042] Specifically, such as Figure 7 As shown, the first drive assembly includes a first X-axis lead screw motor module 11 and a first Z-axis lead screw motor module 12. The first X-axis lead screw motor module 11 is fixed on the worktable 1 by a bracket, and the first Z-axis lead screw motor module 12 is fixedly mounted on the movable seat of the first X-axis lead screw motor module 11. The laser cutting machine 2 is fixedly mounted on the movable seat of the first Z-axis lead screw motor module 12. The lead screw motor module is existing technology and will not be described in detail here. Thus, the laser cutting machine 2 can be driven to move in the X-axis and Z-axis directions respectively.

[0043] Furthermore, such as Figure 7 and Figure 8As shown, the clamping mechanism 3 includes a fixed clamping seat 31, a movable clamping seat 32, a pair of positioning rods 33, and a second drive assembly. The fixed clamping seat 31 and the movable clamping seat 32 are horizontally arranged opposite each other on the worktable 1, and their arrangement direction is the X-axis direction. The movable clamping seat 32 is slidably mounted on the worktable 1 in a direction closer to or farther from the fixed clamping seat 31. The second drive assembly is used to drive the movable clamping seat 32 to slide. The second drive assembly is a second X-axis lead screw motor module 34. The movable clamping seat 32 is fixedly mounted on the movable seat of the second X-axis lead screw motor module 34. The lead screw motor module is prior art and will not be described in detail here. The rods 33 are respectively clamped and fixed on the opposite side of the fixed clamping seat 31 and the movable clamping seat 32 by the claws. The position between the two positioning rods 33 is located directly below the laser cutting machine 2. The two positioning rods 33 are respectively used to insert into both ends of the metal tube, and the end of the positioning rod 33 used to insert into the metal tube is frustum-shaped. Therefore, after the laser cutting is completed, the movable clamping seat 32 is driven to move away from the fixed clamping seat 31, so that one positioning rod 33 leaves the metal tube. Since the end face of the positioning rod 33 is frustum-shaped, the metal tube can slide away from the other positioning rod 33 by its own gravity and fall into the receiving groove 141 of the support 14.

[0044] Furthermore, such as Figure 1 , Figure 7 and Figure 8 As shown, the feeding mechanism 4 includes a feeding box 41, a sliding seat 42, a pair of clamping plates 43, a clamping cylinder 44, and an ejector. The feeding box 41 is fixedly installed on the workbench 1. A horizontally extending discharge hole 411 is provided on the bottom side wall of the feeding box 41 for a single metal tube to pass through. The sliding seat 42 is slidably installed on the workbench 1 in the Y-axis direction and is located on one side of the feeding box 41. The workbench 1 is equipped with a second driving member 18 for driving the sliding seat 42 to slide. The second driving member 18 is a cylinder and is fixedly installed on the workbench 1. The piston rod of the second driving member 18 is fixedly connected to the sliding seat 42. The clamping cylinder 44 is fixedly installed on the sliding seat 42. The two clamping plates 43 are arranged vertically opposite each other and are respectively Two grippers are fixedly installed on the clamping cylinder 44. The position between the two clamping plates 43 corresponds to the discharge hole 411. The opposite sides of the two clamping plates 43 are provided with grooves for the metal tube to be inserted. The ejector is used to eject the metal tube corresponding to the discharge hole 411 to the position between the two clamping plates 43. Therefore, after the metal tube corresponding to the discharge hole 411 is ejected from the loading box 41, the clamping cylinder 44 is activated, and the metal tube is clamped by the two clamping plates 43. Then, the second drive 18 is activated to transport the metal tube to the position between the two positioning rods 33. When the moving clamping seat 32 is driven to move towards the fixed clamping seat 31, the metal tube can be pushed so that its two ends are respectively inserted into the position between the two positioning rods 33, thus completing the loading.

[0045] The ejector includes an ejector rod 45 and an ejector cylinder 46. The size of the ejector rod 45 is the same as the size of the discharge hole 411. One end of the ejector rod 45 is horizontally facing the end of the discharge hole 411 away from the clamping plate 43. The ejector cylinder 46 is fixedly installed on the worktable 1. The piston rod of the ejector cylinder 46 extends and retracts in the X-axis direction. The piston rod of the ejector cylinder 46 is fixedly connected to the other end of the ejector rod 45. Thus, by activating the ejector cylinder 46, the ejector rod 45 is driven to insert into the discharge hole 411, thereby ejecting the metal tube.

[0046] Furthermore, such as Figure 7 and Figure 9 As shown, the feeding box 41 includes a collecting chamber 412 and a discharging chamber 413. The discharging chamber 413 is located at one end of the bottom of the collecting chamber 412. The width of the discharging chamber 413 is sufficient for a single metal tube to pass through. The bottom of the collecting chamber 412 extends downwards towards the discharging chamber 413. The discharge hole 411 is located at the bottom of the discharging chamber 413. Therefore, after the metal tube raw material is manually placed into the feeding box 41, the metal tube can enter the discharging chamber 413 sequentially by its own gravity.

[0047] The implementation principle of a laser cutting device according to an embodiment of this application is as follows: During processing, the ejector cylinder 46 is first activated to eject the metal tubes one by one to the position between the two clamping plates 43, and the clamping cylinder 44 is activated to clamp the metal tubes; then the second driving component 18 is activated to transport the metal tubes to the position between the two positioning rods 33.

[0048] Start the second X-axis lead screw motor module 34 to drive the moving clamp 32 to move closer to the fixed clamp 31, and insert the two positioning rods 33 into the two ends of the metal tube to complete the positioning; then start the first X-axis lead screw motor module 11 and the first Z-axis lead screw motor module 12 to drive the laser cutting machine 2 to move to the corresponding cutting position of the metal tube, and start the laser cutting machine 2 to complete the cutting.

[0049] Then, the drive cylinder 15 is activated, causing the support 14 to move directly below the metal tube. The second X-axis lead screw motor module 34 is then activated, causing the moving clamp 32 to move away from the fixed clamp 31, releasing the metal tube. The metal tube then falls into the receiving groove 141 of the support 14. The drive cylinder 15 is activated again, causing the support 14 to move between the air nozzle 16 and the dust collection hood 17. The air nozzle 16 blows away the cutting debris, which is then extracted through the dust collection hood 17. The support 14 continues to move downwards until the pusher plate 151 passes through the through hole 142, pushing the metal tube away from the support 14. The metal tube rolls in the feeding trough 13 until it comes into contact with the buffer block 52. Then, the lifting cylinder 54 is activated to push the metal tube into the collection box group 6. When the metal tube rolls into the open collection box 61, it can enter the corresponding collection box 61. After the collection in one collection box 61 is completed, the servo motor 514 is activated to drive the drive block 512 away from the previous collection box 61. The cover plate 62 of the collection box 61 closes by its own gravity. Then, it moves to the position of the rubber roller 622 corresponding to the next collection box 61 and drives the cover plate 62 of the next collection box 61 to open, and continues to collect materials.

[0050] Once the metal pipes of the corresponding specifications have been collected in the same collection box group 6, the conveyor belt 7 is started, and the conveyor belt 7 transports the next collection box group 6 to the discharge port position.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
