Description

Technical Field

[0001] This invention relates to the field of radar processing technology, and in particular to a radar dome coating and pressing equipment. Background Technology

[0002] With the development of technology, radar applications have gradually entered various fields of daily life. In order to protect the normal operation of radar in harsh environments, workers usually attach radomes to radars such as vehicle-mounted radars, weather radars, and navigation radars that need to adapt to different environments. This protects the main structure of the radar. During the bonding process between the radome and the radar, because the radome is produced by molding, there is a "surface layer" with weak physical and chemical properties after demolding. This surface layer is mainly composed of mold release agent residue, low molecular weight resin components, and an incompletely cured layer formed by air inhibition. Therefore, it is easy for the bonding to be weak. At this time, it is necessary to use a pressing equipment to provide external pressure to press the two together to enhance the bonding strength between the radar and the radome.

[0003] Existing radome bonding and pressing equipment, while strengthening the bond through extensive application of adhesive and pressure, suffers from weak adhesion and interlocking due to the thin "surface layer." This results in insufficient reliability of the connection between the radar and the radome, making the finished product unsuitable for harsh weather conditions and significantly reducing its applicability and lifespan. Pre-processing the radome's bonding surface before bonding further impacts production efficiency due to the inefficiency of the processing flow. In addition to pre-treating the bonding surface, workers must measure each radome individually and address any defects, compromising processing precision and further compromising process flow. This also affects the bonding speed between the radome and the radar. Therefore, we propose a radome adhesive application and pressing equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the weak "surface layer" of radome bonding due to the molding process in the prior art is not conducive to bonding reliability, and to propose a radome adhesive coating and pressing device.

[0005] To achieve the above objectives, the present invention employs the following technology: a radar dome adhesive coating and pressing device, comprising a fixed base, a pressing mechanism and an adhesive coating mechanism above the fixed base, a support plate rotatably connected inside the fixed base, a rotating ring coaxially fixed on the upper part of the support plate, a driving mechanism on one side of the support plate, the driving mechanism driving the support plate to rotate, and a grinding mechanism above the fixed base; the grinding mechanism includes a limiting plate fixed on the rear side of the top surface of the fixed base, a movable block slidably connected in the middle of the limiting plate, sandpaper in frictional contact with the radar dome on the bottom surface of the movable block, a first annular groove coaxially formed on the top surface of the rotating ring, multiple guide blocks fixed in an annular, equally spaced structure on the inner sidewall of the first annular groove, a guide rod fixed on the bottom surface of the movable block in sliding contact with the sidewall of the guide block, the guide rod shifting away from the radar dome when squeezed by the guide block, a supporting spring fixed between the rear wall of the movable block and the inner wall of the limiting plate; an airbag connected to the rear side of the movable block, an air cavity communicating with the interior of the airbag being formed inside the movable block, and multiple air outlets being formed on the bottom surface of the air cavity.

[0006] As a further description of the above technical solution: a second annular groove coaxial with the first annular groove is formed at the edge of the top surface of the rotating ring. A connecting groove is formed between the first annular groove and the second annular groove. Two guide plates are provided in a centrally symmetrical structure in the connecting groove. The guide plates are set in an inclined structure. The outer ends of the front and rear guide plates extend into the second annular groove and the first annular groove, respectively. The guide plates are rotatably connected to the inner wall of the connecting groove through a hinge shaft. When the guide rod and the guide plate are pressed into contact with the side wall of the connecting groove, the guide plate does not rotate. A torsion spring is sleeved in the middle of the hinge shaft.

[0007] As a further description of the above technical solution: a fixed plate is fixedly provided at the end of the airbag away from the movable block. The fixed plate is connected and fixed to the inner wall of the limiting plate. The fixed plate is slidably connected to the movable block. Openings are provided at both ends of the airbag. An air inlet communicating with the inside of the airbag is provided on the fixed plate. A notch is provided on the limiting plate at the position relative to the air inlet.

[0008] As a further description of the above technical solution: multiple air outlets are arranged in a T-shape, a partition is fixed at the lower part of the air chamber, the partition divides the air chamber into two parts, multiple air outlets above the sandpaper are arranged in a straight line and located behind the partition, multiple air outlets on the front side of the sandpaper are arranged in a square array and located in front of the partition, and the lower part of the air outlets is arranged in an inclined rearward structure.

[0009] As a further description of the above technical solution: the upper and lower sides of the air cavity opening end are both hinged with a first baffle by a torsion spring. The first baffle can only rotate inward into the air cavity. The air inlet is hinged with a second baffle by a torsion spring. The second baffle can only rotate inward towards the airbag.

[0010] As a further description of the above technical solution: the movable block is provided with extrusion rods on both sides, and two pins are symmetrically fixed at both ends of the extrusion rods. The side wall of the movable block is provided with slots that engage with the pins. The end of the pin is U-shaped and has two protrusions in the radial direction. The slot is provided with a groove that engages with the protrusions. The side wall of the movable block is provided with a rod groove that engages with the extrusion rods. The two extrusion rods respectively extrude and fix the two ends of the sandpaper in the two rod grooves.

[0011] As a further description of the above technical solution: the adhesive application mechanism includes a movable frame slidably connected to the top surface of the movable block, a compression spring fixed between the movable frame and the top surface of the movable block, a sleeve fixed to the front side of the movable frame, the upper part of the sleeve is inclined, the lower end of the sleeve is a T-shaped cylindrical structure, a discharge pipe is slidably arranged at the lower open end of the sleeve, the top surface of the discharge pipe is a closed structure, the lower end of the discharge pipe is a V-shaped structure, and two discharge ports are symmetrically opened at the upper part of the discharge pipe. The discharge ports are normally blocked by the inner wall of the lower side of the sleeve.

[0012] As a further description of the above technical solution: two sliding rods are symmetrically fixed on both sides of the discharge pipe. The sliding rods are slidably connected to the bottom surface of the sleeve. A return spring is fixed between the top surface of the sliding rod and the inner wall of the sleeve. A corrugated pipe is connected to the rear of the sleeve. A glue bucket is fixed on the top surface of the limiting plate. The rear end of the corrugated pipe extends through the front wall of the glue bucket into its interior. An internally threaded pipe is provided through the top surface of the glue bucket. A threaded cap is threadedly connected to the internally threaded pipe.

[0013] As a further description of the above technical solution: the pressing mechanism includes a fixed frame fixed on the top surface of the fixed seat, a hydraulic rod fixed on the bottom surface of the fixed frame, a three-jaw chuck fixed at the lower end of the hydraulic rod, and a radar held in the three-jaw chuck.

[0014] As a further description of the above technical solution: a radar dome is inserted inside the tray, and the outer wall of the tray is connected and fixed to the bottom surface of the rotating ring by multiple connecting rods. The inner wall of the tray has a ring-shaped structure with multiple rubber strips that are in contact with the outer wall of the radar dome. The driving mechanism includes two gears rotatably connected inside the fixed base. The two gears are meshed and connected. One gear is coaxially fixedly connected to the lower part of the tray, and the top surface of the other gear is coaxially fixedly connected to a servo motor. The servo motor is connected and fixed to the fixed base.

[0015] In summary, the beneficial effects of this invention, which employs the aforementioned technology for a radar dome adhesive bonding device, are as follows: The invention includes a grinding mechanism. Through the cooperation of the guide rod in the grinding mechanism with the first annular groove on the rotating ring and the guide block in the first annular groove, the movable block can reciprocate back and forth during the rotation of the rotating ring. Then, the sandpaper on its bottom surface can grind the weak "surface" of the radar dome's bonding surface. This action not only resembles manual grinding and has a good grinding effect, but also ensures consistent grinding force and direction, helping to improve grinding accuracy. The radar dome bonding surface ground in this way can avoid adhesion... If a loose bond occurs, the rough surface created by sanding can increase the contact area between the adhesive and the bonding surface, improving the adhesion between the adhesive and the bonding surface and thus enhancing the bonding effect between the radar and the radar cover. At the same time, during the back-and-forth movement, the airbags can intermittently blow air onto the sanding surface and the top surface of the sandpaper. The former can blow away the residual powder on the sanding surface, ensuring that the bonding effect is not reduced due to dust. The latter can cause the sandpaper to vibrate at a high frequency through Bernoulli's principle, which can help shake off the dust on the sandpaper and prevent the powder adhering to the sandpaper from affecting the sanding effect.

[0034] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a radar dome coating and pressing device of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-12As shown, the present invention provides a radar dome adhesive bonding device, including a fixed base 10. The upper part of the fixed base 10 is a U-shaped structure with an opening facing forward, allowing operators to maintain the internal parts of the device from the front opening. A support plate 11 is rotatably connected inside the fixed base 10, and a radar dome is inserted inside the support plate 11. A rotating ring 12 is coaxially fixed on the upper part of the support plate 11. The outer wall of the support plate 11 and the bottom surface of the rotating ring 12 are connected and fixed by multiple connecting rods 111. The inner wall of the support plate 11 has a ring-shaped structure with multiple rubber strips 112 that are in contact with the outer wall of the radar dome. The rubber strips 112 can press the radar dome inside the support plate 11. The pressure and friction can cause the radar dome to rotate together when the support plate 11 rotates.

[0036] A drive mechanism 30 is provided on one side of the pallet 11. The drive mechanism 30 drives the pallet 11 to rotate. The drive mechanism 30 includes two gears 31 rotatably connected inside the fixed base 10. The two gears 31 are meshed together. One gear 31 is coaxially and fixedly connected to the lower part of the pallet 11, and the top surface of the other gear 31 is coaxially and fixedly connected to a servo motor 32. The servo motor 32 is connected and fixedly connected to the fixed base 10. The servo motor 32 is controlled by a PLC controller and operates according to the following steps:

[0037] S1. The meshing of two gears 31 drives the pallet 11 and its structure to rotate in the first rotation direction.

[0038] S2. After rotating a specified number of times, the servo motor 32 first stops rotating, and then drives the pallet 11 to rotate in the second rotation direction through the two gears 31. The second rotation direction is opposite to the first rotation direction.

[0039] S3. After the pressing process is completed and a new set of radar domes is installed, repeat S1.

[0040] A grinding mechanism 40 is provided above the fixed base 10. The grinding mechanism 40 includes a limiting plate 41 fixedly mounted on the rear side of the top surface of the fixed base 10. A movable block 42 is slidably connected to the middle of the limiting plate 41 to ensure that the movable block 42 does not rotate with the rotating ring 12. The bottom surface of the movable block 42 is provided with sandpaper 43 that rubs against the radar dome. Extrusion rods 48 are provided on both sides of the movable block 42. The middle of the extrusion rod 48 is a cylindrical structure. Two pins 481 are symmetrically fixed at both ends of the extrusion rod 48. The side wall of the movable block 42 is provided with a plug that engages with the pins 481. The slot 425 and the pin 481 have a U-shaped end with two radial protrusions. The slot 425 has a groove that engages with the protrusions. By inserting the two, the extrusion rod 48 can be fixed on the side wall of the movable block 42. The side wall of the movable block 42 has a rod groove 426 that engages with the extrusion rod 48. The two extrusion rods 48 respectively extrude and fix the two ends of the sandpaper 43 in the two rod grooves 426, thereby fixing the sandpaper 43. The simple insertion and removal structure also makes it convenient for workers to replace the sandpaper 43 after long-term use.

[0041] A first annular groove 121 is coaxially formed on the top surface of the rotating ring 12. Multiple guide blocks 122 are fixedly mounted on the inner wall of the first annular groove 121 in a ring-shaped, equally spaced arrangement. The guide blocks 122 create a wave-like structure on the inner wall of the first annular groove 121. A guide rod 44 is fixedly mounted on the bottom surface of the movable block 42, sliding in contact with the side wall of the guide block 122. When the guide rod 44 is pressed by the guide block 122, it moves away from the radar dome. A support spring 45 is fixed between the rear wall of the movable block 42 and the inner wall of the limiting plate 41. During the rotation of the rotating ring 12, the guide block 122 presses the guide rod 44 backward, and then... When the position corresponds to the two adjacent guide blocks 122, the rebound force of the support spring 45 will push the rearward moving block 42 forward, so that the moving block 42 moves back and forth as a whole. In this way, the sandpaper 43 can perform the sanding operation on the radome. During the rotation in the first rotation direction, the sandpaper 43 can fully sand the bonding surface of the radome. This not only removes the weak "surface layer" on the radome caused by the molding process, but also forms a rough surface on the bonding surface, increases the bonding area between the glue and the radome, and thus increases the bonding strength between the radome and the radar.

[0042] A second annular groove 123, coaxial with the first annular groove 121, is formed at the top edge of the rotating ring 12. A connecting groove 124 is formed between the first annular groove 121 and the second annular groove 123. Two guide plates 125 are centrally symmetrically arranged in the connecting groove 124. The guide plates 125 are inclined and rotatably connected to the inner wall of the connecting groove 124 via a hinge shaft 126. A torsion spring 127 is sleeved in the middle of the hinge shaft 126. In the first rotation direction, the outer ends of the front and rear guide plates 125 extend into the second annular groove 123 and the first annular groove 121, respectively. The guide rod 44 is always in contact with the side wall of the guide plate 125 in the first annular groove 121 away from the connecting groove 124. After being squeezed, 125 will rotate into the connecting groove 124 and open a passage, allowing the guide rod 44 to continue sliding contact with the first annular groove 121. When the rotation direction changes to the second rotation direction, the guide rod 44 will contact the side wall of the guide plate 125 near the connecting groove 124. Since the guide plate 125 does not rotate when the guide rod 44 is squeezed into contact with the side wall of the guide plate 125 near the connecting groove 124, the guide rod 44 will be guided outward by the inclined guide plate 125. Finally, the guide rod 44 will enter the path of the second annular groove 123. Then, in the second rotation direction, similarly to the above, the guide rod 44 will maintain sliding contact with the second annular groove 123 until the rotating ring 12 changes back to the first rotation direction.

[0043] An airbag 46 is connected to the rear side of the movable block 42. An air chamber 421 communicating with the interior of the airbag 46 is opened inside the movable block 42. Multiple air outlets 422 are opened on the bottom surface of the air chamber 421. A fixing plate 47 is fixedly installed at the end of the airbag 46 away from the movable block 42. The fixing plate 47 is connected and fixed to the inner wall of the limiting plate 41. The fixing plate 47 is slidably connected to the movable block 42. Openings are provided at both ends of the airbag 46. An air inlet 471 communicating with the interior of the airbag 46 is opened on the fixing plate 47. A notch is provided on the limiting plate 41 at the position corresponding to the air inlet 471. A partition 423 is fixedly installed at the lower part of the air chamber 421, dividing the air chamber 421 into two parts. The two parts divided by the partition 423 are of different sizes. The upper part is L-shaped and has a larger space, while the lower part is straight and has a smaller space. With this design and at the two opening ends, the gas squeezed into the air chamber 421 by the airbag 46 is divided into two parts and injected into the upper and lower sides respectively. The opening end of the air chamber 421 is hinged to the upper and lower sides of the partition 423 by a torsion spring, and the first baffle 424 can only be opened to the upper and lower sides. The air chamber 421 rotates internally. A second baffle 472 is hinged to the air inlet 471 via a torsion spring. The second baffle 472 can only rotate towards the airbag 46. With this structure, the first baffle 424 and the second baffle 472 act as one-way valves at the openings on both sides of the airbag 46, allowing outside air to enter the airbag 46 from the air inlet 471 and exit from the air outlet 422. This direction is irreversible. During the backward movement of the movable block 42, the airbag 46 contracts due to the reaction force of the inner wall of the limiting plate 41. As the space inside the chamber shrinks, the gas inside will be discharged from the air outlet 422. The discharged gas has a large flow rate and fast velocity for the area being polished, which can disperse the dust generated during polishing and prevent it from remaining on the bonding surface and affecting the bonding effect. During the subsequent forward movement of the movable block 42, because the front and rear ends of the airbag 46 are connected and fixed to the movable block 42 and the fixed plate 47 respectively, the airbag 46 will be pulled to its original position. In addition, the elasticity of the airbag 46 can quickly replenish the airbag 46 with sufficient air for the next use.

[0044] Multiple air outlets 422 are arranged in a T-shape. Above the sandpaper 43, multiple air outlets 422 are arranged in a straight line and positioned behind the partition 423. The limited number of air outlets 422 ensures that the gas injected into the lower air chamber 421 can effectively act on the sandpaper 43. The straight arrangement of the air outlets 422 can also cause the middle of the sandpaper 43 to vibrate. Because the sandpaper 43 is a soft structure and not easily damaged, and its ends are fixed by the compression rods 48, and because the lower air chamber 421 and its opening are extremely limited by the partition 423, the gas will only create a very narrow gap between the sandpaper 43 and the moving block 42. According to Bernoulli's principle, if the gap is narrow and the airflow is fast, the pressure will decrease accordingly. Since sandpaper 43 has extremely poor air permeability, the air on its other side is relatively still and the pressure is relatively high. This pressure difference will generate a net pressure, pushing the paper to move towards the low-pressure area. Sandpaper 43 itself has a certain degree of flexibility and elasticity. When the airflow continues to act, the restoring force of sandpaper 43 after deformation will try to pull it back to its original position, which will cause sandpaper 43 to shake. This will shake off the dust that adheres to sandpaper 43 due to the sanding operation. Compared with manual cleaning, this cleaning method is not only convenient and quick but also more thorough.

[0045] Multiple air outlets 422 on the front side of the sandpaper 43 are arranged in a square array and positioned in front of the partition 423. The multiple air outlets 422 arranged in a square array on the front side blow the air in the upper air chamber 421 onto the radome, thereby blowing off the dust left on it, ensuring the cleanliness of the bonding surface, and thus ensuring that the bonding is firm and not affected by dust. The lower part of the air outlets 422 is set with a structure that is inclined to the rear. This structure allows the air outlets 422 on the front side to act on the bonding surface of the radome, while also causing the air from the rear air outlets 422 to blow backward to avoid collision with the airflow on the front side and cause dust residue.

[0046] A pressing mechanism 20 is provided above the fixed base 10. The pressing mechanism 20 includes a fixed frame 21 fixed on the top surface of the fixed base 10, a hydraulic rod 22 fixed on the bottom surface of the fixed frame 21, and a three-jaw chuck 23 fixed at the lower end of the hydraulic rod 22. The radar is held in the three-jaw chuck 23. The operator can fix the radar or remove the device together with the glued radar and radar cover by controlling the opening and closing of the jaws of the three-jaw chuck 23.

[0047] Above the fixed base 10, there is also a glue application mechanism 50. The glue application mechanism 50 includes a movable frame 51 slidably connected to the top surface of the movable block 42. The lower end of the movable frame 51 has a T-shaped structure. The top surface of the movable block 42 has a groove that slides with the lower end of the movable frame 51. The groove is also T-shaped so that the movable frame 51 can move horizontally within it. A compression spring 511 is fixed between the movable frame 51 and the top surface of the movable block 42 to ensure that the movable frame 51 maintains its relative position with the movable block 42 without the influence of external force. A sleeve 52 is fixed to the front side of the movable frame 51. The upper part of the movable frame 51 has an L-shaped structure. Its two ends are fixed to the rear end and the middle of the sleeve 52 by two ring structures, respectively, to ensure the stability of the sleeve 52 when it moves together with the movable frame 51.

[0048] A glue bucket 54 is fixed on the top surface of the limiting plate 41. An internal threaded tube 541 is provided through the top surface of the glue bucket 54. A threaded cap 542 is threadedly connected to the internal threaded tube 541. Glue can be added into the glue bucket 54 by unscrewing the threaded cap 542.

[0049] The lower end of the sleeve 52 has a T-shaped cylindrical structure. A discharge pipe 53 is slidably installed at the open end of the lower side of the sleeve 52. The top surface of the discharge pipe 53 is a closed structure. Two discharge ports 531 are symmetrically opened on the upper part of the discharge pipe 53. The discharge ports 531 are normally blocked by the lower inner wall of the sleeve 52. Two sliding rods 532 are symmetrically fixed on both sides of the discharge pipe 53. The sliding rods 532 are slidably connected to the bottom surface of the sleeve 52. A return spring 533 is fixed between the top surface of the sliding rod 532 and the inner wall of the sleeve 52. Under the influence of no external force, the discharge pipe 53... Finally, under the combined action of the return spring 533 and gravity, it remains in the lower position inside the sleeve 52, and the discharge port 531 on it is also kept blocked by the inner wall of the sleeve 52. Although the glue will be poured into the sleeve 52 under the influence of gravity and the principle of communicating vessels, the glue will stay inside the sleeve 52 because the discharge pipe 53 is blocked. A corrugated pipe 521 is connected to the rear of the sleeve 52. The rear end of the corrugated pipe 521 extends through the front wall of the glue bucket 54 and into its interior. The middle part of the corrugated pipe 521 is set with a downward curved U-shaped structure.

[0050] In the second rotation direction, the guide rod 44 will drive the movable block 42 outward. At this time, the bottom surface of the movable block 42 will completely detach from the radome, and the grinding work will be completed. The glue application mechanism 50 located on the movable block 42 will also move outward simultaneously. Since the lower end of the discharge pipe 53 has a V-shaped structure and its inclined position can press against the radome, the inclined side wall of the discharge pipe 53 will rise along the inside of the sleeve 52 after being pressed by the inner wall of the radome. Then, the discharge port 531 on it will connect with the inside of the sleeve 52, and the glue in the sleeve 52 will be transferred to the sleeve. Water will enter the discharge pipe 53 from the discharge port 531 and eventually flow out from the lower end of the discharge pipe 53. As the guide rod 44 slides in contact with the second annular groove 123, the lower end of the discharge pipe 53 will also make annular sliding contact with the radome bonding surface. This not only completes the glue application operation, but also achieves the effect of a dispensing process, which can improve the accuracy of glue application and ensure that the narrow annular structure of the radome bonding surface can also be fully and evenly coated with glue, ensuring the bonding effect and sealing quality. Furthermore, this glue application process can also reduce the amount of glue consumed and reduce waste.

[0051] The upper part of the sleeve 52 is inclined. After the radome rotates once under the drive of the support plate 11 and the rotating ring 12, the glue application mechanism 50 has completed the glue application operation on its bonding surface. Then, the operator can operate the pressing mechanism 20 to press the radar down. The edge of the radar will squeeze the inclined part of the sleeve 52 from above, so that the sleeve 52 moves backward with the moving frame 51. Then the lower end of the discharge pipe 53 will pass over the bonding surface of the radome. Under the action of gravity and the rebound force of the return spring 533, the discharge pipe 53 moves down and is once again blocked by the inner wall of the sleeve 52 at the discharge port 531. The glue stops flowing out. The removed sleeve 52 can no longer block the bonding of the radome and the radar. The operator only needs to press the two together for a sufficient time through the pressing mechanism 20 to ensure that the bonding surfaces of the two are fully bonded under the action of the glue. In this way, the processing of the radar and the radome is completed.

[0052] It should be noted that the servo motor 32 in this device drives the tray 11 and the rotating ring 12 to rotate at a uniform and relatively slow speed, which allows sufficient time for the grinding operation of the grinding mechanism 40 and the gluing operation of the gluing mechanism 50. At the same time, the number of rotations in the first rotation direction needs to ensure that the number of rotations in which the guide rod 44 slides in contact with the first annular groove 121 is an integer number of rotations, and that there are enough rotations for the grinding operation. The number of rotations in the second rotation direction needs to ensure that the number of rotations in which the guide rod 44 slides in contact with the second annular groove 123 is at least one full rotation, so that the gluing operation can completely cover the annular bonding surface of the radar dome.

[0053] Working principle: The operator can fix the radar and radome onto the three-jaw chuck 23 and the support plate 11 of this device, respectively. Then, the servo motor 32 drives the support plate 11 and the rotating ring 12 to rotate. In the first rotation direction, the grinding mechanism 40 grinds the bonding surface of the radome to eliminate the weak "surface" produced by the molding process and increase the contact area between the bonding surface and the adhesive. Then, the servo motor 32 drives the support plate 11 to rotate in the second rotation direction to apply adhesive to the bonding surface of the radome. After the adhesive is applied, the pressing mechanism 20 is used to press the two together and apply the adhesive to bond them. Finally, the pressing mechanism 20 is used again to lift the bonded product out of the support plate 11, and the operator can then operate the three-jaw chuck 23 to release the radar and remove the finished product.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technology of the radar dome coating and pressing device and the inventive concept of the present invention, should be covered within the scope of protection of the present invention.
