Description

Technical Field

[0001] The invention relates to the technical field of power transformer manufacturing, in particular to a wire stripping device for processing a power transformer. Background Art

[0002] A power transformer is a device used to change AC voltage. It transfers electrical energy from one circuit to another through the principle of electromagnetic induction while changing the voltage. In power supply systems, transformers play a vital role and are widely used in power transmission, distribution and conversion.

[0003] In the production process of power transformers, the wires are the medium for power transmission, and their connection quality directly affects the performance and safety of the transformer. In order to ensure reliable connection between wires, it is usually necessary to strip the wires, that is, remove the insulation skin on the outer layer of the wires to expose the metal conductor inside, so as to carry out subsequent connection operations such as welding and crimping.

[0004] In the existing wire stripping process, the wire is usually stripped manually or using a simple mechanical device. This process is not only inefficient, but also difficult to stably control the stripping quality. The connection between two stripped wires currently relies mostly on manual operation, which is carried out by welding or winding. This connection method is not only inefficient, but also has the problem of unstable connection quality. In addition, due to the intervention of manual operation, not only the production cost and labor intensity are increased, but also the wire connection may become loose or have poor contact, thereby affecting the overall performance and safety of the power transformer. Therefore, there is an urgent need for a device that can efficiently and stably complete wire stripping and automatic winding connection to overcome the shortcomings of the existing technology and meet the needs of power transformer production.

[0048] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1-Figure 16The embodiment of the present invention provides a technical solution: comprising a base 1 and a slide rail 4 arranged on the base 1, wherein the base 1 is used to install various components, wherein a universal wheel may be arranged at the bottom of the base 1 to facilitate its movement, which is a conventional arrangement of the universal wheel, and will not be described in detail herein, the wire stripping device for processing a power transformer also includes:

[0050] The cutting mechanism for cutting the outer skin of the wire is arranged on the slide rail 4 through the driving mechanism, and the driving mechanism has two stroke actions, the first stroke action: driving the cutting mechanism to cut the outer skin of the wire; the second stroke action: driving the cutting mechanism to separate from the wire after cutting; when the driving mechanism is started, the cutting mechanism moves toward the position close to the wire, so that the outer skin of the wire is cut by the arranged cutting mechanism, and after the wire is cut, the cutting mechanism is moved away from the wire by the driving mechanism, so that the outer skin of the wire can be cut, wherein the driving mechanism is a driving motor;

[0051] The peeling mechanism is arranged on the base 1 and connected to the cutting mechanism. After the cutting mechanism cuts off the outer skin of the wire, the peeling mechanism separates the cut outer skin of the wire from the wire core. After the outer skin of the wire is cut off by the cutting mechanism, the peeling mechanism can separate the cut outer skin of the wire from the wire without manual peeling, and has an automatic peeling effect.

[0052] The conveying mechanism is arranged on the base 1 and connected to the cutting mechanism. When the cutting mechanism is driven to separate from the wire by the driving mechanism, the conveying mechanism is used to convey the stripped wire to the inside of the wire stripping device away from the conveying mechanism. The wire to be stripped can be placed into the wire stripping device for stripping through the conveying mechanism. After the stripping is completed and the cut wire skin is separated from the wire, the wire is continuously pushed into the wire stripping device to perform the next operation on the stripped wire.

[0053] A connecting assembly is arranged on the base 1, and is used to connect the wire transported by the transport mechanism with an external wire;

[0054] The connecting assembly comprises a winding mechanism, a clamping mechanism and a transmission mechanism. The winding mechanism and the clamping mechanism are respectively connected to the cutting mechanism through the transmission mechanism. When the conveying mechanism stops conveying the wire and the driving mechanism is still driving the cutting mechanism and the wire is in a state of separation, the transmission mechanism drives the clamping mechanism to clamp and fix the external wire to be connected. Then, the winding mechanism winds the wire conveyed by the conveying mechanism onto the outside of the wire clamped by the clamping mechanism. By setting the transmission mechanism, the clamping mechanism and the winding mechanism, the external stripped wire can be clamped through the clamping mechanism, and then, under the action of the transmission mechanism, the winding mechanism is used to clamp the wire. The wire stripped by the wire stripping device is wound on the outer surface of the external wire to achieve the connection of the two wires. After the wire stripping is completed, the two wires can be automatically wound and connected, which simplifies the subsequent processing steps of the power transformer. There is no need to manually connect the two stripped wires. In the case of using some thicker wires in the power transformer, the difficulty of connecting the two wires is also increased. The connection of the two stripped wires is automatically completed, which saves manpower and prevents the sharp ends of the wires from causing harm to the staff when the two stripped wires are manually connected, thereby greatly improving the use effect.

[0055] In one embodiment of the present invention, the conveying mechanism includes two feed wheels 3 rotatably arranged on a door frame 2, the door frame 2 is fixed on the base 1, and the feeding action of the wire is realized through the interval between the two feed wheels 3. When the wire needs to be stripped, the wire to be fed and stripped is first inserted into the wire stripping device through the gap between the two feed wheels 3 to a suitable depth, and then the insertion of the wire is stopped. At this time, the end of the wire is inserted into the wire stripping device, so that the next step of wire stripping can be carried out;

[0056] In another embodiment of the present invention, the cutting mechanism includes a screw rod 61 rotatably arranged on the base 1 and two lifting plates 62 threadedly installed on the screw rod 61 and with the ends slidably engaged in the slide rail 4. The two lifting plates 62 are respectively fixed with an upper connecting rod 6 and a lower connecting rod 63. A knife seat 65 is installed on the surfaces close to each other between the upper connecting rod 6 and the lower connecting rod 63 through a spring 64, and a plurality of stripping knives 66 for stripping the outer skin of the wire are arranged on the knife seat 65. The driving mechanism is connected to the screw rod 61. At this time, after the wire is plugged in, the driving mechanism is started to rotate the screw rod 61. At this time, the lifting plate 62 threadedly connected to the screw rod 61 will drive the upper connecting rod 6 and the lower connecting rod 63 to move. When it is necessary to cut the skin of the wire, the driving mechanism is controlled to make the upper connecting rod 6 and the lower connecting rod 63 close to each other, so that the stripping knives 66 on the knife seat 65 are close to each other until the two halves of the stripping knives 66 collide with each other. At this time, the wire skin is cut by the stripping knives 66.

[0057] It should be noted that the stripping knife 66 should be consistent with the specifications of the wire to be stripped. When the two stripping knives 66 are against each other, the stripping knives 66 will just cut off the skin of the wire.

[0058] It should also be noted that a plurality of grooves adapted to the guide are provided on the surface of the feed wheel 3. When feeding the wire, the wire is inserted into the wire stripping device through the grooves on the feed wheel 3, and the stripping knives 66 on the knife holder 65 are also provided with the same number, so that the skins of multiple wires can be cut at the same time;

[0059] See also Figure 7 After the wire skin is cut, the stripping knife 66 is just in a state of abutment, and the upper connecting rod 6 and the lower connecting rod 63 are both provided with a limit post 67. When the stripping knife 66 abuts against each other to cut the wire skin, the limit post 67 of the upper connecting rod 6 abuts against the raised position of the knife seat 65 on the lower connecting rod 63, and the limit post 67 on the lower connecting rod 63 abuts against the raised position of the knife seat 65 on the upper connecting rod 6.

[0060] In another embodiment of the present invention, a transverse plate 7 is fixedly provided on the shell surface of the slide rail 4, and the peeling mechanism includes two groups of drive shafts 52 rotatably provided on the transverse plate 7, meshing teeth 53 provided on the outer surface of the drive shaft 52, and two groups of racks 5 fixedly provided on the upper connecting rod 6 and meshing with the meshing teeth 53. A screw rod 51 is designed on the end of each of the two drive shafts 52, and internal thread blocks 54 are threadedly provided on each of the two screw rods 51, and pressure plates 57 are installed on each of the two internal thread blocks 54 through elastic members; when the upper connecting rod 6 and the lower connecting rod 63 are close to each other, the stripping knife 66 is used to remove the wire. When the epidermis is cut, the rack 3 5 moves downward with the upper connecting rod 6, thereby rotating the drive shaft 52 through the meshing tooth 1 53, thereby rotating the screw rod 1 51, and the two teeth 3 are set at opposite positions of the two meshing teeth 1 53, so that when the upper connecting rod 6 moves, the two drive shafts 52 rotate in opposite directions, and at this time, the internal thread blocks 54 on the two screw rods 1 51 are not limited, so they follow the two screw rods 1 51 to rotate in the direction of the center position until the pressure plates 57 on the internal thread blocks 54 on the two screw rods 1 51 abut against each other, and the elastic member on the pressure plate 57 is deformed to the maximum, at which time the two pressure plates 57 abut against each other. The elastic member can be a torsion spring;

[0061] It should be noted that when feeding the wire, the insertion depth of the wire should exceed the surface of the two pressure plates 57 close to the cutting mechanism side, so that after the two pressure plates 57 abut against each other, the wire will be pressed in the middle to achieve clamping of the wire, and when the stripping knife 66 completes cutting the epidermis of the wire, the two clamping plates 810 now complete the clamping of the wire, and then it should be noted here that there is no need to turn off the driving mechanism, and continue to control the driving mechanism to make the upper connecting rod 6 and the lower connecting rod 63 approach each other, because at this time the limit column 67 of the upper connecting rod 6 abuts against the raised position of the knife seat 65 on the lower connecting rod 63, and the limit column 67 on the lower connecting rod 63 now abuts against the raised position of the knife seat 65 on the upper connecting rod 6, When the rod 6 and the lower connecting rod 63 continue to approach, the two knife seats 65 and the stripping knife 66 cannot approach each other, but squeeze the spring 1 64 to compress and deform, so that the upper connecting rod 6 and the lower connecting rod 63 can still approach each other without damaging the stripping knife 66. At this time, due to the mutual squeezing of the two pressing plates 57, they form a limit with each other, so that the two internal thread blocks 54 cannot continue to rotate with the screw rod 1 51, but move on the screw rod 1 51, thereby driving the two pressing plates 57 to move, so that the cut wire skin is pulled out by moving the pressing plates 57, so that the wire skin is separated from the wire, and the wire with the cut skin can be automatically checked and separated from the skin, without manual operation, and it is more convenient to use;

[0062] It should be noted that when the peeling is completed, the driving mechanism is controlled to make the screw rod 2 61 rotate in the opposite direction. At this time, the upper connecting rod 6 and the lower connecting rod 63 move away from each other, so that the two driving shafts 52 will drive the two screw rods 1 51 to rotate in opposite directions, and the internal thread block 54 and the pressure plate 57 move away from the center position. At this time, in order to allow the pressure plate 57 and the internal thread block 54 on the peeling mechanism to be able to return to their original positions when the screw rod 1 51 is reversed so as to facilitate the next separation of the cut epidermis, the peeling mechanism also includes two limit clamps 56 installed on the base 1 through the stand 55, and the limit clamps 56 are provided with grooves that are compatible with the ends of the pressure plates 57. After the pressing plate 57 rotates toward the center conductor position and clamps the conductor, the pressing plate 57 is inserted into the notch of the matching limiting clamp 56, so that when the two pressing plates 57 are mutually limited and move on the screw rod 1 51, the limiting clamp 56 and the stand 55 are pulled to move together until the epidermis is peeled off. When the two screw rods 1 51 are reversed, the two internal thread blocks 54 and the pressing plate 57 are not limited due to the reverse rotation, and move with the screw rod 1 51 away from the center conductor position until the pressing plate 57 is clamped into the notch of the limiting clamp 56 on the other side. At this time, due to the limitation of the limiting clamp 56, it can no longer rotate with the screw rod 1 51, so it moves in the opposite direction on the screw rod 1 51 until it returns to its original position.

[0063] When the wire is stripped, the driving mechanism is controlled to make the screw rod 2 61 rotate in the opposite direction, and the upper connecting rod 6 and the lower connecting rod 63 move away from each other. At this time, the lower connecting rod 63 moves downward. At this time, it is necessary to continue to feed the stripped wires to carry out the next step of the wire operation. In another embodiment of the present invention, the conveying mechanism also includes a rack 36 fixed on the lower connecting rod 63, and a gear 31 rotatably set on the door frame 2 and respectively connected to the two feeding wheels 3. A gear 2 34 meshing with the rack 36 is also rotatably set on the surface of the door frame 2 close to the gear 1 31. The gear 2 34 is provided with a protrusion 32 inserted into the inside of one of the gears 1 31, wherein a block 33 is rotatably set on the protrusion 32 through a torsion spring, and a circular array is formed on the inner wall surface of the gear 2 34. A ratchet groove 1 35 is provided, and a clamping block 1 33 abuts against the surface of the ratchet groove 1 35, and a one-way power transmission action of the gear 2 34 to the gear 1 31 is realized through the clamping block 1 33 and the ratchet groove 1 35 that are arranged against each other; when the lower connecting rod 63 moves downward, the rack 1 36 moves downward, and the rack 1 36 meshes with the gear 2 34, so that the gear 2 34 rotates, thereby the two gears 1 31 rotate through the gear 2 34, and since the two gears 1 31 mesh with each other, the rotation directions of the two gears 1 31 are opposite, and at this time, the two feed wheels 3 rotate in opposite directions, and since the feed wheel 3 is provided with irregular protrusions, when the feed wheel 3 rotates, the protrusions will abut against the surface of the wire, so that the wire is further transported to the wire stripping device through friction with the surface of the wire;

[0064] It should be noted that when the upper connecting rod 6 and the lower connecting rod 63 approach each other to cut the wire, the rack 1 36 moves upward, and due to the setting of the ratchet groove 1 35 and the block 1 33, the ratchet groove 1 35 and the block 1 33 slip, and the gear 2 34 cannot drive the gear 1 31 to rotate. That is to say, when the connecting rod 1 and the connecting rod 2 approach each other, the two feed wheels 3 do not rotate. Only when the cutting is completed and the skin is separated from the wire by the peeling mechanism, and the upper connecting rod 6 and the lower connecting rod 63 are moved away from each other by the driving mechanism, the two feed wheels 3 will rotate, so that when stripping the wire, there will be no interference with the stripping, but secondary feeding will be performed after the stripping is completed.

[0065] In another embodiment of the present invention, the clamping mechanism includes a mounting plate 819 arranged on the base 1 through the frame 10, and a plurality of groups of forward and reverse screws 822 are rotatably arranged in the mounting plate 819, and two driving plates 821 are threadedly arranged on each group of forward and reverse screws 822, and the two driving plates 821 are provided with a clamping plate 810 slidably arranged on the surface of the mounting plate 819, and the two clamping plates 810 are connected by a spring 820, and the transmission mechanism is arranged between the end of one of the forward and reverse screws 822 at the end and the lower connecting rod 63, and when the lower connecting rod 63 moves away from the wire, the forward and reverse screws 822 are rotated by the transmission mechanism, so that the two clamping plates 810 are moved closer to each other;

[0066] Before the wire is stripped by the cutting mechanism, the wire that has been stripped is inserted into the gap between the two clamping plates 810, and when the upper connecting rod 6 and the lower connecting rod 63 are close to each other, the two clamping plates 810 clamp the ends of the wire that has been stripped by the transmission mechanism;

[0067] When the wires in the wire stripping device are stripped and transported through the conveying mechanism, the winding mechanism includes a turntable 813 with the same number as the positive and negative lead screws 822 and is rotatably arranged on the mounting plate 819 through the telescopic rod 811, and the surface of each turntable 813 is provided with meshing teeth three 814, and the meshing teeth three 814 on the two adjacent turntables 813 mesh with each other, and a winding seat 812 is fixed at an eccentric position on the surface of each turntable 813, wherein the meshing teeth three 814 on the surface of the turntable 813 at one end is connected to the lower connecting rod 63 through a transmission mechanism, and when the lower connecting rod 63 moves away from the wire, the multiple groups of turntables 813 are rotated through the transmission mechanism, and when the clamping mechanism clamps the wire stripped externally through the transmission mechanism and connects the two wires through the winding mechanism, the rack 1 36 is separated from the gear 2 34, and the wire stops feeding at this time, and the two feeding wheels 3 are in the initial state at this time, so as to facilitate the next insertion of the wire;

[0068] It should be noted here that when the feed wheel 3 stops feeding, that is, when the wire stops moving, the upper connecting rod 6 and the lower connecting rod 63 are still in a state of moving away from each other. At this time, the wire is fed into the gap between the winding seat 812 and the inserted external wire that has been stripped. At this time, the external wire is locked by the clamping mechanism, and then the turntable 813 is rotated through the transmission mechanism, so that the winding seat 812 in the eccentric position rotates. When the winding seat 812 rotates, it contacts the wire and presses the wire on the external surface of the external wire. As the winding seat 812 rotates, the winding seat 812 winds the wire on the outer surface of the external wire, and can connect the two wires after the wire stripping is completed without subsequent manual operation. For some wires with larger cross-sectional areas, the inconvenience caused by manual winding is greatly reduced. The number of turntables 813 is set to be the same as the number of strippers 66, which can not only strip multiple wires, but also automatically connect multiple groups of wires, simplifying the process when processing the power transformer and having a better convenience effect.

[0069] It should also be noted that, since the meshing teeth 814 on the adjacent rotating disks 813 mesh with each other, the rotation directions of the two adjacent rotating disks 813 are opposite, so that the winding seats 812 on the two adjacent rotating disks 813 can be wound in opposite directions when winding the wires, so as to meet the use of different power transformer windings, etc. It should be noted that, in order to achieve this effect, the positions of the adjacent winding seats 812 on the rotating disk 813 are opposite and offset by 180 degrees;

[0070] In another embodiment of the present invention, a slide groove 8 on which a slider 81 is slidably installed is provided on the base 1, and the transmission mechanism includes one end of a rotating plate 82 rotatably arranged on the lower connecting rod 63, and the other end of the rotating plate 82 is rotatably arranged with the slider 81, and a gear three 84 and a gear four 88 are rotatably arranged on the base 1, wherein the axis of the gear three 84 is vertically upward, and the axis of the gear three 84 is arranged in a direction perpendicular to the movement direction of the slider 81, and a rack two 86 and a meshing tooth two 87 are arranged on the slider 81. When the lower connecting rod 63 moves away from the wire, after the gear two 34 meshes with the gear three 84, the meshing tooth two 87 meshes with the gear four 88, and the gear four 88 and the end of a group of forward and reverse screws 822 on one end are installed with a synchronous belt one 83 through a synchronous wheel;

[0071] A connecting shaft 85 is fixedly provided on the gear three 84, and a driving wheel 816 is installed on the top of the connecting shaft 85 through a moving part. The driving wheel 816 is rotatably set on the inner wall surface of the gear five 815, and a ratchet groove 2 828 is clamped on the inner wall of the gear five 815. The end of the driving wheel 816 extending into the gear five 815 is installed with a clamping block 2 827 that abuts against the surface of the ratchet groove 2 828 through a torsion spring. The gear five 815 meshes with the meshing tooth three 814 on one of the turntables 813; when the upper connecting rod 6 and the lower connecting rod 63 move away from each other, the lower connecting rod 63 presses the slider 81 through the rotating rod to move the slider 81 away from the lower connecting rod 63. The restriction will cause the meshing tooth 2 87 on the slider 81 to mesh with the gear four 88, and the positive and negative threads are meshed through the synchronous belt 1 83. The lever 822 rotates, so that the two clamping plates 810 are close to each other, so as to clamp the external wire. At this time, the spring 2 820 is compressed and deformed. Then, when the lower connecting rod 63 continues to move downward, the rack 2 86 meshes with the gear 3 84, and the gear 5 815 is rotated through the connecting shaft 85 via the moving part, so that the multiple groups of turntables 813 are rotated through the meshing gear 3 814. After the wire surface is stripped, after the upper connecting rod 6 and the lower connecting rod 63 are separated, and after the conveying mechanism stops conveying the wire, the two clamping plates 810 on the clamping mechanism are clamped to the end of the external wire through the transmission mechanism. After the clamping is completed, the turntable 813 is rotated to wind the wire stripped by the stripping device onto the surface of the external wire through the winding seat 812.

[0072] The ratchet groove 828 and the block 827 are arranged so that when the upper connecting rod 6 and the lower connecting rod 63 approach each other to strip the wire next time, the gear 815 will not rotate when the rotating plate 82 drives the slider 81 to move in the reverse direction, so that the winding seat 812 on the rotating disk 813 will not rotate, thereby preventing the winding seat 812 from reversing and interfering with the wire of the wire stripping device along the feeding position;

[0073] In the above-mentioned winding, after the wire stripping device strips the wire and winds it around the external wire, it can only be wound for one circle, or even less than one circle. In order to further improve the winding effect, in another embodiment of the present invention, the moving part includes a movable ring 823 slidably arranged on the connecting shaft 85, and an insertion rod 824 arranged on the end of the connecting shaft 85 and passing through the driving wheel 816 and the gear five 815, wherein a card slot 826 is provided on the driving wheel 816, and a limit block 825 engaged in the card slot 826 is fixedly provided on the outer peripheral side of the insertion rod 824, and a support frame 9 slidably connected to the lifting block 817 is fixedly provided on the mounting plate 819, and a cam 818 is fixedly provided on the end of the forward and reverse screw 822 at one end, and the cam 818 is against the bottom surface of the lifting block 817;

[0074] The moving part further includes a plurality of groups of snap rings 829 respectively arranged on the outer peripheral sides of the gear 5 815 and the rotating disk 813. The plurality of groups of snap rings 829 are arranged alternately, and the protruding positions of adjacent snap rings 829 are snapped into the concave positions of adjacent snap rings 829.

[0075] When the forward and reverse screws 822 are rotated by the meshing of gear 4 88 and meshing tooth 3 814 and the external wire is clamped by the clamping plate 810, the spring 2 820 is compressed and deformed, and when the gear 3 84 is meshed with the rack 2 86, the gear 4 88 and the meshing tooth 3 814 will not separate. At this time, the spring 2 820 is continuously compressed, and the forward and reverse screws 822 are still in a rotating state, so that the cam 818 on the forward and reverse screws 822 at one end is also in a rotating state. At this time, the winding seat 812 winds the wire stripped by the wire stripping device on the external wire, and the cam 818 is separated from the lifting block 817 when rotating. Under the action of gravity, the gear 5 815 and the driving wheel 816 slide downward. Due to the multiple sets of clamping rings 829 The convex positions of adjacent clamping rings 829 are staggered, and the convex positions of adjacent clamping rings 829 are clamped in the concave positions of adjacent clamping rings 829, so that the multiple groups of turntables 813 will move downward, thereby reducing the height of the winding seat 812. Since the end of the winding seat 812 is set to be larger than the diameter of the wire, when the winding seat 812 descends, it will hook the wire and descend together, thereby winding the wire downward toward the outside guide until it descends to the lowest point. At this time, the lower connecting rod 63 moves down to the maximum position, and the driving mechanism is closed. When winding the wire, it can be wound not only once, but multiple times, which further improves the winding effect of the wire and greatly reduces the difficulty of spiral winding and connecting the wire in the processing of the power transformer, and has an excellent use effect.

[0076] In order to improve this effect, cams 818 are provided at the ends of the two square screw rods at both ends, and a spring can be installed in the telescopic rod 811, so that when the cam 818 rotates, the multiple turntables 813 can be stably lowered or raised;

[0077] In order to facilitate the removal of the wires after the two wires are connected, a notch is provided on the plurality of rotating disks 813 for the wires to be removed after the connection. An elastic plate 830 is provided at the notch position of the rotating disk 813 through a torsion spring. A tooth matching the meshing tooth 3 814 is provided on the outer peripheral surface of the elastic plate 830. In this way, the wires can be removed by directly pulling the wires outward. The teeth provided on the elastic plate 830 will not affect the rotation of the rotating plate 82. It should be noted that the teeth need to be arranged away from the rotation position of the elastic plate 830.

[0078] It should also be noted that in order to further improve the effect of winding the wire stripped by the wire stripping device around the external wire, as Fig.11As shown, the clamping mechanism can be set into two groups, and the other group of clamping mechanisms is set above the winding mechanism, and the clamping mechanism located above is provided with a through hole for the external wire to enter on the mounting plate 819 between the clamping plates 810, and the ends of the forward and reverse screws 822 on the two clamping mechanisms are installed with a synchronous belt 89 through a synchronous wheel, so that the outside of the external wires on both sides of the winding mechanism can be clamped by the two clamping mechanisms at the same time, so that the external wires are fixed, to prevent the external wires from shaking and affecting the winding effect when the wires are wound around the external wires.

[0079] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above 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.
