Description

Technical Field

[0001] The present invention relates to the technical field related to mechanical manufacturing and automated assembly, and in particular to rotor assembly equipment. Background Art

[0002] Some electric toothbrushes and high-speed hair dryers use micro high-speed motors. The rotors are composed of a shaft and a permanent magnet. The shaft is engraved with grooves, and a permanent magnet is mounted and fixed on the shaft. The grooves on the two ends of the shaft are different to accommodate different assembly requirements and installation processes. In other words, the shaft is divided into two ends. The diameter of the permanent magnet is larger than that of the shaft. The shaft is inserted into the middle of the permanent magnet and the two are fixed. The permanent magnet is a hollow cylindrical structure and is mounted on the shaft.

[0003] An existing permanent magnet and rotor assembly device, application number CN202411585729.X, is not capable of assembling the above-mentioned type of rotor, and is not equipped with an instrument to detect the stability of the rotor after assembly.

[0004] For example, there is a rotor assembly machine with application number CN201811358224.4, which can assemble a single rotor. However, if mass production is required, workers are still required to load and unload materials. At the same time, the equipment cannot autonomously distinguish the head and tail of the shaft to perform corrective actions, so it cannot meet the requirements of rotor production. Summary of the Invention

[0005] The object of the present invention is to provide a rotor assembly device to overcome the deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A rotor assembly device is used to efficiently and accurately assemble a rotor shaft and permanent magnets to form a rotor, achieving automated production. The device includes a receiving bar, a permanent magnet feeding mechanism, a shaft feeding mechanism, a pre-insertion device, a transport mechanism, a gluing mechanism, and a testing mechanism. These modules work together to automate the entire process, from loading, assembly, gluing, to quality inspection.

[0008] The accommodating bar extends along a preset conveying path and is used to carry and guide the permanent magnet and the rotor. A sinking position is provided on the top thereof, which can accommodate the permanent magnet and ensure that the rotating shaft is partially exposed to the outside, so as to facilitate subsequent processing. A pair of horizontal bars of the accommodating bar are arranged with a gap, and the spacing is not less than the diameter of the permanent magnet or the rotating shaft, so as to ensure that the rotor can move freely and be stably positioned during the conveying process. Furthermore, the width of the sinking position is slightly larger than the outer diameter of the permanent magnet, and the depth is one-half to two-thirds of the height of the permanent magnet, so that the permanent magnet maintains a horizontal posture during the conveying process, while the upper part of the rotating shaft is exposed outside the sinking position, so as to facilitate subsequent processing operations.

[0009] The permanent magnet feeding mechanism includes a permanent magnet vibrating disk, a second feeding tube, a stopper, a translation jig, and a permanent magnet pushing cylinder. The permanent magnet vibrating disk is used to sort and feed the permanent magnets; the second feeding tube is connected to the discharge end of the permanent magnet vibrating disk to transport the permanent magnets to the designated position; the stopper is provided at the end of the second feeding tube to temporarily block and position the permanent magnets; the translation jig is slidably mounted on the stopper, and is provided with a jig opening for accommodating the permanent magnets, which is used to move the permanent magnets horizontally and place them on the receiving bar; the permanent magnet pushing cylinder further pushes the permanent magnets to the position to be transported by the transfer mechanism. Among them, the inner wall of the jig opening of the translation jig is provided with an elastic buffer layer to prevent the permanent magnets from being damaged by collisions during the transfer process.

[0010] The shaft feeding mechanism is responsible for supplying shafts and unifying their orientation through a reversing assembly. Specifically, it comprises a shaft vibrating plate, a shaft feeding tube, and a reversing assembly. The shaft vibrating plate is used to sort and feed the shafts; the shaft feeding tube connects the vibrating plate to the pre-insertion device and is used to feed the shafts. The reversing assembly, located in the middle of the shaft feeding tube, identifies and corrects the shaft orientation, ensuring that all shafts are fed in the same direction. The reversing assembly comprises an interruption frame, a rotary valve core, an optical camera, and a reversing motor. The interruption frame has offset feed and discharge ports and houses a rotary valve core. The rotary valve core is rotatably mounted within the interruption frame and defines a passage for the shafts to pass through. The optical camera captures images of the shafts entering the rotary valve core and determines their orientation. The reversing motor, based on the optical camera's determination, drives the rotary valve core to rotate by a preset angle, allowing the shafts to pass directly when in the correct orientation or to flip and be fed out when in the wrong orientation. Specifically, the inner wall of the passage of the rotary valve core is coated with a non-slip coating to reduce frictional losses during the shaft's reversing process.

[0011] The pre-insertion device is arranged at the pre-insertion station on the accommodating bar, and is used to preliminarily insert the rotating shaft into the permanent magnet to form a semi-finished rotor. Its structure includes a transfer frame, a push-out block and a lower insertion cylinder. The transfer frame is arranged above the pre-insertion station, and one end is connected to the discharge end of the rotating shaft feeding mechanism; the push-out block is slid inside the transfer frame, and is controlled by the cylinder to move back and forth, and is used to push the rotating shaft to the predetermined unloading position; the lower insertion cylinder is mounted above the transfer frame, and its piston rod extends downward, and is used to press the rotating shaft into the permanent magnet to complete the pre-insertion action. Furthermore, a flexible pressure head is provided at the end of the piston rod of the lower insertion cylinder to avoid damage to the surface of the rotating shaft during the pressing process.

[0012] The transfer mechanism is used to transfer the semi-finished rotor and the finished rotor from the current station to the next station in steps along the conveying path of the accommodating bar. Its structure includes an X-axis translation driver, a Y-axis translation driver and a transfer plate. The X-axis translation driver is arranged along the conveying path parallel to the accommodating bar, and is used to control the overall left and right translation; the Y-axis translation driver is installed on the X-axis translation driver, and is used to control the front and back translation; the transfer plate is fixed to the output end of the Y-axis translation driver, and a plurality of clamps are provided at the front end for moving the permanent magnet or the rotor. In particular, the inner wall of the clamp of the transfer plate is provided with an anti-slip pad to ensure that the rotor will not shift during the transfer process.

[0013] The gluing mechanism, located downstream of the pre-insertion station, is used to apply glue to the exposed shaft portion of the semi-finished rotor and complete the final press-fit. Its structure comprises a clamping and rotating assembly, a glue dispensing syringe, and a striker assembly. The clamping and rotating assembly includes a lowering cylinder, a first bracket, a finger clamping cylinder, and a rotary motor, which clamp and rotate the shaft to achieve circular glue application. The glue dispensing syringe is controlled by a glue feeding cylinder, and its glue outlet contacts the rotating shaft to complete the gluing process. The striker assembly includes a pressing cylinder, which is used to fully press the glue-coated shaft into the permanent magnet. Furthermore, the glue outlet of the glue dispensing syringe is equipped with a flow control device to ensure precise control of the glue application amount.

[0014] The detection mechanism is arranged downstream of the gluing mechanism and is used to perform quality inspection on the finished rotor after pressing. Its structure includes a glue erasing assembly, an ejector assembly and a height detection part. The glue erasing assembly includes a pair of opposing paper rollers, glue erasing paper and a glue erasing cylinder, which are used to wipe glue that may overflow from the top of the finished rotor; the ejector assembly includes an ejector cylinder, which is used to test the stability of the connection between the rotating shaft and the permanent magnet; the height detection part includes a height detection cylinder and a pressure detector, which is used to detect whether the final height of the rotating shaft after being pressed into the permanent magnet meets the standard. In particular, a conical ejector is provided at the end of the piston rod of the ejector cylinder, whose diameter is slightly smaller than the diameter of the rotating shaft, to ensure that the rotating shaft will not be damaged during the test.

[0015] The equipment also includes a sorting cylinder for sorting finished rotors into either a finished product bin or a defective bin. Based on the detection results, the sorting cylinder switches the connection between the strip outlet and the finished product bin or defective bin. This switching action is controlled in real time by a controller based on feedback from the detection mechanism, ensuring the accuracy and timeliness of the sorting process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The incorporation of a reversing assembly enables automatic correction of the shaft's direction, eliminating manual intervention and improving assembly efficiency. The integration of multiple automated functional modules automates the entire process, from loading, assembly, gluing, and testing, reducing manual labor and ensuring assembly quality. The synergistic effects of the gluing assembly, ejector assembly, and height detection components enable comprehensive quality testing of finished rotors to meet the demands of mass production. In particular, the rational design of the connections between modules ensures stable and reliable operation, making the equipment suitable for mass production in applications such as micro high-speed motors.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered thereon. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may also be an element centered thereon. When the number of an element is referred to as having "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings:

[0033] like Figure 1-9 As shown, in this embodiment, a rotor assembly device is provided, including a shaft feeding mechanism and a permanent magnet feeding mechanism 2, a pre-insertion device 4, a transfer mechanism, a receiving strip 1, a gluing mechanism 6 and a detection mechanism. Specifically, the positions of the above-mentioned various components are arranged such that the shaft feeding mechanism and the permanent magnet feeding mechanism 2 are both arranged on the upper side of the pre-insertion device 4, and a transfer mechanism is arranged on one side of the pre-insertion device 4. The function of the accommodating bar 1 is to be able to place a pair of horizontal bars of the permanent magnet to be assembled. The horizontal bars are symmetrically fixed on the machine base, wherein the pair of horizontal bars are arranged with gaps, and the top of the horizontal bars is provided with a sinking position. From the cross-section of the combination of a pair of horizontal bars, it is equivalent to providing a groove with a larger gap at the top of the horizontal bar. This is mainly because when placing the rotor, the diameter of the permanent magnet is larger than the diameter of the shaft, and when assembled on the horizontal bar, the bottom of the permanent magnet abuts against the sinking position and is stuck between the pair of horizontal bars. Note that the spacing between the pair of horizontal bars is not less than that of the shaft or the permanent magnet, that is, the width of the sinking position is not less than that of the permanent magnet. When placed, the permanent magnet is located at the sinking position, and the shaft extends below the sinking position. Each rotor is freely placed on the accommodating bar 1.

[0034] The above-mentioned permanent magnet feeding mechanism 2 can place the permanent magnet on the placement bar first, and the shaft feeding mechanism can send the shaft to the pre-insertion device 4, and then the pre-insertion device 4 inserts the shaft into the permanent magnet. The plug-in at this time is pre-plug-in, that is, a part of the shaft is still above the permanent magnet and is not completely pressed into place, which is also to facilitate the subsequent gluing action.

[0035] After pre-insertion, when the transfer mechanism continuously transports new rotors to be assembled, the rotors are continuously fed in, and the leading rotors are continuously pushed forward by the rotors coming behind.

[0036] The pre-inserted rotor will come to the gluing mechanism 6 to rotate the shaft for gluing and final crimping. The final crimping is to completely insert the half-shaft portion coated with glue into the permanent magnet.

[0037] After the gluing and crimping are completed, they will be transported to the testing agency to absorb excess glue, and to test the connection stability of the rotor and the insertion height of the shaft.

[0038] Specifically, the shaft feeding mechanism includes a shaft vibration disk 39, a shaft feeding pipe 38 and a reversing assembly. The shaft feeding pipe 38 is respectively connected to the pre-insertion device 4 and the shaft vibration disk 39. The shaft fed by the shaft feeding pipe 38 returns to the pre-insertion device 4. The shaft vibration disk 39 is located at a high position. The reversing assembly is located in the middle of the feeding pipe, that is, the shaft will pass through the reversing assembly. The specific reversing assembly includes a reversing motor 15, an interruption frame 12, an optical camera 14 and a rotary valve core 13. The specific interruption frame 12 is provided with a feed port and a discharge port, and the feed port and the discharge port are respectively connected to the feeding pipe, and a rotary valve core 13 is provided. It is rotatably connected to the interruption frame 12, and the rotary valve core 13 also has a channel for the shaft to pass through. The output end of the reversing motor 15 is fixedly connected to the rotary valve core 13. The reversing motor 1 5 can control the rotation of the rotary valve core 13 to determine whether the channel is connected to the discharge port of the interruption frame 12. It should be noted that the feed port and the discharge port of the interruption frame 12 are not located on the same straight line. The specific method of controlling the direction of the rotating shaft is to provide an optical camera 14. The optical camera 14 is arranged on one side of the rotary valve core 13, wherein the outer wall of the rotary valve core 13 is provided with an observation port. In the normally open state, the rotary valve core 13 is connected to the feed port of the interruption frame 12. The rotating shaft moves into the rotary valve core 13 after being guided out by the vibrating disk. The optical camera 14 determines whether the rotating shaft entering the rotary valve core 13 is correct through the observation port. Because one end of the rotating shaft is provided with a pattern or the patterns at both ends of the rotating shaft are different, the optical camera 14 can identify it and control the rotation of the above-mentioned motor through an industrial controller.

[0039] Generally, when the rotating shaft enters the rotary valve core 13 through the feed port, the channel inside the rotary valve core 13 is only connected to the feed port, and the discharge port is not connected to the channel inside the valve core. After the optical camera 14 makes a judgment, the motor will control the rotary valve core 13 to rotate a certain angle. For example, if the direction of the rotating shaft is forward, only the channel of the rotary valve core 13 needs to be rotated by a certain angle difference to connect with the discharge port of the interruption frame 12. If the direction of the rotating shaft is opposite, the motor controls the rotary valve core 13 to flip the rotating shaft over and then connect it with the discharge port, so that it can be ensured that the direction of the rotating shaft coming out is uniform.

[0040] Specifically, the permanent magnet feeding mechanism 2 includes a permanent magnet vibration disk 8, a second feeding tube 9, a translation jig 11 and a stopper 10. The above-mentioned vibration disk transports the permanent magnet to the stopper 10 through the second feeding tube 9, and the translation jig 11 translates the permanent magnet temporarily placed at the stopper 10 and places it on the accommodating bar 1. Specifically, a accommodating opening is opened on one end of the accommodating bar 1, and the translation jig 11 can move the above-mentioned permanent magnet through this accommodating opening to the above-mentioned sinking position, waiting for transportation by the transfer mechanism. Specifically, the stopper 10 is arranged on one side of the accommodating bar 1, and the translation jig 11 is slidably arranged at the stopper 10. The movement of the specific translation jig 11 is realized by arranging a horizontal translation, and the translation jig 11 is provided with a jig mouth with a diameter slightly larger than the permanent magnet. When the permanent magnet falls, it can fall into the jig mouth, and then be translated to the accommodating bar 1 by the translation jig 11. At the same time, a permanent magnet pushing cylinder 37 is also set up at the translation jig 11. Specifically, after the translation jig 11 moves the permanent magnet out to the accommodating bar 1, the permanent magnet pushing cylinder 37 further pushes the forward permanent magnet to the position to be transported by the transport mechanism. The piston rod of the permanent magnet pushing cylinder 37 can penetrate the translation jig 11 and abut against the permanent magnet.

[0041] Further explanation, the transport mechanism includes an X-axis translation drive 19, a transport piece 21 and a Y-axis translation drive 20. The transport piece 21 is installed on the output end of the Y-axis translation drive 20. The Y-axis translation drive 20 and the X-axis translation drive 19 are preferably cylinders. The transport piece 21 is fixed on the piston rod of the Y-axis translation drive 20. The Y-axis translation drive 20 is used to control the forward and backward translation of the transport piece 21, and the Y-axis translation drive 20 is installed on the X-axis. The translation drive 19, specifically the X-axis translation drive 19 is a rodless cylinder, and the Y-axis translation drive 20 is installed in the middle of the X-axis translation drive 19. The X-axis translation drive 19 can control the overall left and right translation of the Y-axis translation drive 20, and the front end of the transfer piece 21 is provided with a plurality of clamps with a diameter slightly larger than the diameter of the permanent magnet. Therefore, the transfer piece 21 cooperates with the X-axis translation drive 19 and the Y-axis translation drive 20 to continuously send the permanent magnet to the front. Specifically, there are four clamps, the first clamp moves the permanent magnet to the pre-insertion device 4, the second clamp is responsible for moving the pre-inserted permanent magnet to the material detection part, the third clamp moves the permanent magnet from the material detection part to the glue coating part, and the fourth clamp moves the permanent magnet from the glue coating part to the installation part. Each time the X-axis translation driver 19 completes the left and right translation of the transfer plate 21, the Y-axis translation driver 20 controls the transfer plate 21 to retract backward, and then the X-axis translation driver 19 resets to prepare for the next Y-axis translation driver 20 to control the transfer plate 21 to be ejected.

[0042] Further elaboration, the pre-insertion device 4 includes a transfer frame 16, inside the transfer frame 16 is slidably provided with a push-out block 17 controlled by a cylinder to move forward and backward, and the transfer frame 16 is arranged above the containing strip 1, and a lower insertion cylinder 18 is arranged above the transfer frame 16, the piston rod of the lower insertion cylinder 18 extends downward for the purpose of inserting the shaft into the permanent magnet. One end of the transfer frame 16 is connected with a shaft feeding pipe 38, and the piston rod of the lower insertion cylinder 18 penetrates the other end of the transfer frame 16, and one end of the transfer frame 16 is provided with a through hole arranged above the permanent magnet of one of the stations, and specifically, after the push-out block 17 pushes the shaft downward below the lower insertion cylinder 18, the shaft will first fall onto the permanent magnet through the through hole. The piston rod of the lower insertion cylinder 18 extends downward to insert the shaft into the permanent magnet, and it is noted that the insertion is not complete but pre-insertion.

[0043] Further elaboration, the glue applying mechanism 6 includes a glue outlet syringe 26, a syringe holder 40, a glue feeding cylinder 36, a clamping and rotating assembly, and a plunger assembly 27, and specifically, after the permanent magnet with the pre-inserted shaft moves to the glue applying mechanism 6, the glue feeding cylinder 36 will push out the syringe holder 40, and the glue feeding cylinder 36 will push the glue outlet syringe 26 to the shaft for glue application. The specific glue application method is because the clamping and rotating assembly includes a lowering cylinder 22, a first support 23, a finger clamping cylinder 24, and a rotating motor 25, and specifically, the lowering cylinder 22 is arranged above the containing strip 1, the piston rod of the lowering cylinder 22 is fixedly connected with the first support 23, the rotating motor 25 and the finger clamping cylinder 24 are arranged on the first support 23, the rotating motor 25 controls the rotation of the finger clamping cylinder 24 relative to the first support 23 through a belt and a belt pulley, and because the finger clamping cylinder 24 is rotatably connected with the first support 23 through the shaft and the bearing, specifically, when the rotor is moved to the pre-insertion device 4 by the moving mechanism, the glue outlet syringe 26 is controlled to be pushed out forward by the glue feeding cylinder 36, and the glue outlet of the glue outlet syringe 26 contacts the shaft, then the lowering cylinder 22 controls the first support 23 to move downward as a whole, the finger clamping cylinder 24 clamps the shaft, and then the rotating motor 25 controls the rotation of the finger clamping cylinder 24, so that the shaft can be controlled to rotate, that is, the glue can be coated around the shaft; finally, the rotor coated with glue is continuously fed below the plunger assembly 27 on the guide of the containing strip 1, and the plunger assembly 27 is specifically a pressing cylinder arranged above the containing strip 1, the piston rod of the pressing cylinder extends downward, and the rotor coated with glue can be installed into the permanent magnet to complete the final assembly.

[0044] The rear end containing strip 1 is arranged with a plurality of arranged rotors, and under the continuous feeding of the moving mechanism, the rotors will continuously move forward one by one.

[0045] The detection mechanism further comprises a glue wiping assembly, a thimble assembly 31 and a height detection member. The rotor first passes through the glue wiping assembly to wipe off the excess glue on the top of the rotor, then passes through the thimble assembly 31 to test the adhesion stability of the shaft and the permanent magnet, and finally passes through the height detection member to detect whether the shaft is at a uniform installation position.

[0046] Specifically, the glue wiping assembly comprises a pair of opposed paper winding rollers 28, which are arranged on both sides of the accommodating strip 1. The pair of paper winding rollers 28 are rotationally connected to the whole machine through a stand. One of the paper winding rollers 28 is provided with a paper winding motor and a transmission assembly. The paper winding motor controls the one paper winding roller 28 to perform a paper winding action through the transmission assembly, and the other paper winding roller 28 performs a driven paper unwinding action. The pair of paper winding rollers 28 are arranged above the accommodating strip 1. In addition, the glue wiping assembly is further provided with a glue wiping cylinder 30 arranged above the accommodating strip 1. The glue wiping cylinder 30 is provided with a downwardly extending piston rod. A glue wiping block is fixedly arranged at the bottom of the piston rod. The glue wiping block can move downwardly to abut the glue wiping paper 29 to the top of the rotor, so as to wipe off the excess glue.

[0047] The thimble assembly 31 is also provided with a thimble cylinder arranged above the rotor, i.e., the accommodating strip 1. The piston rod of the thimble cylinder extends downwardly. The diameter of the piston rod is smaller than the diameter of the shaft. Therefore, if the connection between the shaft and the permanent magnet is not stable enough, the thimble can push the shaft downwardly, so that the shaft and the permanent magnet are separated.

[0048] The height detection member is realized by a pressure detection cylinder arranged above the accommodating strip 1. Specifically, the height detection member comprises a pressure detector and a height detection cylinder 32. The height detection cylinder 32 is arranged above the accommodating strip 1. The end of the piston rod of the height detection cylinder 32 is provided with the pressure detector 33. The downward extension amount of the piston rod of the height detection cylinder 32 is constant. The bottom of the pressure detector 33 is elastically connected with an abutting cone, specifically through a spring. The pressure detector 33 can monitor the pressure received by the abutting cone. The difference between the feedback to the controller and the preset value is determined, so that all the rotors can be controlled to maintain a uniform installation position.

[0049] The ejector assembly 31 and the height detector are both equipped with a press-down positioning cylinder 34. The press-down positioning cylinder 34 is positioned on one side of the receiving bar 1. A through-hole is provided in the sidewall of the receiving bar 1. A block 35 is fixedly mounted at the end of the piston rod of the press-down positioning cylinder 34. The block 35 has a clamping opening with a diameter slightly greater than or equal to the outer diameter of the permanent magnet. The clamping opening is a semicircular opening recessed inward from one side of the block 35. The clamping opening of the block 35 corresponds to the processing position of the ejector assembly 31 and the height detector. After the block 35 is ejected by the press-down positioning cylinder 34, its clamping opening abuts against the sidewall of the permanent magnet. The block 35 is configured to abut the rotor within the receiving bar 1 through the through-hole in the sidewall of the receiving bar 1, adjusting the position of the delivered rotor and aligning the independent rotor with the working position of the ejector assembly 31 and the height detector, ensuring operational reliability.

[0050] The present invention also includes a sorting cylinder that is finally arranged at the discharge port of the accommodating bar 1. The discharge port of the accommodating bar 1 is connected to a finished product frame and a defective product frame. The connection between the discharge port of the accommodating bar 1 and the finished product frame or the defective product frame can be switched by the sorting cylinder, thereby realizing sorting. If the height detection component detects defective products, it will control the action of the sorting cylinder to connect the discharge port of the accommodating bar 1 with the defective product frame. In the normally open state, the height detection component does not detect defective products, and the discharge port of the accommodating bar 1 is connected to the finished product frame. The various technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above-mentioned 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. For ordinary technicians in this field, without departing from the concept of the present invention, several variations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
