[0062] The following describes an embodiment of the present invention in detail with reference to the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.
[0063] like Figure 1-2 As shown, the magnetic steel assembly device for the flywheel energy storage system of the present invention comprises
[0064] The frame 1 has an operating table 1.1 and a protective cover 2 on the frame 1. The protective cover 2 is not only beautiful but also dustproof. The front side wall of the protective cover 2 has a rotor inlet and outlet for easy removal of the rotor.
[0065] The magnetic steel alignment tool 3 is installed on the operating table 1.1. The magnetic steel alignment tool 3 aligns each group of magnetic steel separated by multiple isolation sheets (because the magnetic steels are attracted together due to their magnetic properties, the isolation sheets are used to separate the magnetic steels in pairs to achieve automatic material removal of the magnetic steels);
[0066] The rotor fixing mechanism 4 is provided at the magnetic steel assembly station of the operating table 1.1. The rotor fixing mechanism 4 fixes the rotor at the magnetic steel assembly station. The rotor assembly surface corresponds to the magnetic steel patch mechanism 7 described later.
[0067] The material storage and feeding mechanism is arranged on the operating table 1.1 on one side of the magnetic steel assembly station and comprises a magnetic steel storage fixture 5 and a feeding mechanism 6. After the magnetic steel is calibrated, it is stored on the magnetic steel storage fixture 5 for easy retrieval. The feeding mechanism 6 comprises a first pusher 6.1 for lifting the magnetic steel in the magnetic steel storage fixture 5 upwards and a second pusher 6.2 for pushing the calibrated magnetic steel into the magnetic steel patch mechanism. Both the first pusher 6.1 and the second pusher 6.2 are made of non-magnetic materials.
[0068] The magnetic steel patch mechanism 7 is arranged above the magnetic steel assembly station. The magnetic steel patch mechanism 7 has a limiting groove 7.1 that is consistent with the height of the second pusher 6.2. The limiting groove 7.1 corresponds to the assembly slot F1 of the rotor F in the upper and lower directions. When the magnetic steel patch mechanism 7 moves downward, it presses the magnet in the limiting groove 7.1 into the assembly slot F1 of the rotor F, realizing automatic magnetic patching.
[0069] Among them, the feeding mechanism 6 also has a horizontally arranged feeding chute (i.e., feeding channel), which is connected to the limiting groove 7.1. The second pusher 6.2 can directly clamp the magnet into the limiting groove 7.1 through the feeding channel. The magnet patch mechanism 7 sticks the magnet in the limiting groove 7.1 into the assembly slot of the rotor, thereby realizing automatic assembly of the magnet and improving assembly efficiency.
[0070] like Figure 2 As shown, there are two sets of material storage and feeding mechanisms and magnetic steel patch mechanisms 7, the two sets of material storage and feeding mechanisms are located on both sides of the magnetic steel assembly station, and the two sets of magnetic steel patch mechanisms 7 are respectively located above the magnetic steel assembly station. The material storage and feeding mechanisms and the magnetic steel patch mechanisms are matched and are two groups, which realizes the simultaneous patching of two magnets and can control the patching time of each rotor within 8 minutes, thereby improving the assembly efficiency; there are also two magnetic steel correction fixtures, which are respectively arranged on both sides of the operating table 1.1 to meet the needs of the two sets of material storage and feeding mechanisms.
[0071] like Figure 3-5As shown, the magnetic steel correction tool 3 includes a first support 3.1 provided on the operating table 1.1. The first support is provided with a clamping correction structure and a first linear power source. The first linear power source is a first cylinder 3.2 (preferably a guide cylinder) provided on the first support. Of course, the first linear power source can also be a hydraulic cylinder, etc.
[0072] The first support 3.1 has a horizontally arranged mounting plate. The clamping and correction structure includes a fixed assembly fixed to the mounting plate and a movable assembly driven left and right by a first cylinder 3.2. The fixed assembly includes a fixed base 3.3 and a fixed clamping block 3.4 fixed together by bolts. The movable assembly includes a movable base 3.5 connected to the positioning top plate of the first cylinder 3.2 and a movable clamping block 3.6 fixed to the movable base 3.5.
[0073] The fixed clamping block 3.4 and the movable clamping block 3.6 are arranged horizontally in the front-to-back direction. The fixed clamping block 3.4 has an L-shaped structure, and its horizontal portion is a support platform 3.4a with a curved surface. The lower portion of the inner side walls of the fixed clamping block 3.4 and the movable clamping block 3.6 has correction grooves 3.7 that cooperate with the two corners of the curved edge of the magnetic steel. In the clamping state, the fixed clamping block 3.4 and the movable clamping block 3.6 enclose a magnetic steel correction groove 3.9 that is consistent with the magnetic steel structure. This can realize automatic correction of each group of magnetic steel, eliminating the need for manual removal of magnetic steel one by one, thereby improving the efficiency of magnetic steel feeding.
[0074] During operation, a group of magnets to be aligned (including spacers) is placed horizontally on the support platform 3.4a in the front-to-back direction, and ensures that one side of the arc-shaped edge of the magnet is uniformly located on the support platform 3.4a; the first cylinder 3.2 drives the movable assembly to move horizontally toward the fixed assembly through the positioning top block 3.8, and the movable clamping block 3.6 moves into place to form a magnet alignment groove 3.9, thereby achieving neat stacking of the group of magnets. The aligned magnet group is as shown in FIG. Figure 5 As shown, Figure 5 In the figure, B1 is a fan-shaped magnet; B2 is a spacer that separates the magnets.
[0075] like Figure 3 As shown, both the fixed component and the movable component are split structures, so that the fixed clamping block 3.4 and the movable clamping block 3.6 can be easily replaced to meet the calibration requirements of magnetic steels of different specifications.
[0076] like Figure 1 As shown, the first support is also provided with a pair of guide blocks 3.10 extending in the front-rear direction. The lower part of the movable seat 3.5 is clamped on the guide blocks 3.10. The movable seat 3.5 moves back and forth along the guide blocks 3.10, effectively ensuring the movement trajectory of the movable seat 3.5 and the movable clamping block 3.6.
[0077] During actual processing, the magnetic steel calibration fixtures (excluding the first cylinder 3.2) are all made of non-magnetic materials, such as nylon or non-magnetic stainless steel, to ensure the calibration of the magnetic steel.
[0078] like Figure 6-8 As shown, the magnetic steel storage tooling 5 includes a first power mechanism, a storage base, and a plurality of magnetic steel inlet and outlet channels 5.1 spaced apart along the circumferential direction of the storage base. The first power mechanism includes a first divider 5.3 driven by a reduction motor 5.2 through a chain transmission pair. A vertically arranged rotating shaft 5.4 is mounted on the first divider 5.3. The reduction motor 5.2 drives the rotating shaft 5.4 to rotate through the chain transmission pair and the first divider 5.3, thereby realizing the rotation of the storage base.
[0079] The material storage base (made of non-magnetic material to avoid magnet attraction) includes an upper limit plate 5.5a and a lower limit plate 5.5b spaced apart from each other, which are fixedly connected together by a connecting column 5.5c. A plurality of circumferentially spaced magnet access channels 5.1 are spaced apart between the upper limit plate 5.5a and the lower limit plate 5.5b and close to the edges of the upper limit plate 5.5a and the lower limit plate 5.5b. The calibrated magnet can be placed from top to bottom in each magnet access channel 5.1 to achieve magnet storage.
[0080] To ensure the smooth entry and exit of the magnets, a through slot 5.5d is provided on the lower limit plate 5.5b corresponding to each magnet entry and exit channel 5.1 to facilitate the passage of the first pusher 6.1, so as to ensure that the first pusher 6.1 can enter from the bottom of the magnet entry and exit channel 5.1 to push the magnet as a whole to move upward; a magnet inlet and outlet 5.5e consistent with the magnet structure is provided on the upper limit plate 5.5a corresponding to each magnet entry and exit channel 5.1 to facilitate the entry and exit of the magnets, thereby realizing the storage and retrieval of the magnets.
[0081] like Figure 8 As shown, the magnet inlet and outlet channel 5.1 is surrounded by multiple limiting columns, which limit and guide the magnets to ensure that each group of magnets can enter and exit smoothly. Of course, in actual installation, the magnet inlet and outlet channel 5.1 can also be a box structure with the same cross-section as the magnet structure.
[0082] like Figure 6 and Figure 9 As shown, the feeding mechanism 6 also includes a second linear power source, a first mounting seat 6.5, a third linear power source, and a recovery assembly. The first mounting seat 6.5 is mounted above the magnetic steel storage fixture 5, the second linear power source is located on one side of the magnetic steel storage fixture 5, the recovery assembly is arranged opposite the second linear power source, and the third linear power source is set on the first mounting seat 6.5. The specific structures are as follows:
[0083] like Figure 6 、 10 -11, the second linear power source includes a first motor 6.4a arranged at the material-retrieving station and a first lead screw 6.4b driven by the first motor 6.4a, the motor base of the first motor 6.4a is fixed on the frame 1, and the other end of the first lead screw 6.4b is connected to the first mounting base 6.5 through the first connecting base 6.4c; a lifting block 6.4d is threadedly connected to the first lead screw 6.4b, and the first pusher 6.1 is arranged on the lifting block 6.4d, and the first pusher 6.1 is fixed on the lifting block 6.4d. During operation, the first motor 6.4a drives the first pusher 6.1 to rise and fall through the first lead screw 6.4b and the lifting block 6.4d. The first pusher 6.1 pushes the magnets from the bottom of each group of magnets to move upward along the magnet inlet and outlet channel 5.1 to realize automatic material removal of the magnets; when the magnets in the magnet inlet and outlet channel 5.1 are completely pushed out, the first pusher 6.1 descends to the bottom of the lower limit plate 5.5b to ensure the normal rotation of the magnet storage tooling 5, so as to facilitate the pushing of the next group of magnets.
[0084] like Figure 10-11 As shown, during actual installation, to ensure the movement trajectory of the lifting block 6.4d and the first push handle 6.1, a pair of vertically extending first guide posts 6.4e are provided between the motor base and the first connecting base 6.4c. The lifting block 6.4d has through-holes that mate with the first guide posts 6.4e. The lifting block 6.4d is inserted into the first guide posts 6.4e to ensure the linear movement trajectory of the lifting block 6.4d.
[0085] like Figure 10 As shown, the first mounting seat 6.5 is horizontally arranged above the magnetic steel storage tooling 5. A horizontal slider 6.6 driven by a third linear power source is provided on the first mounting seat 6.5. The third linear power source includes a synchronous belt drive pair driven by a second motor 6.7a and a second lead screw 6.7b connected to the synchronous belt drive pair. The horizontal slider 6.6 is threadedly connected to the second lead screw 6.7b. The second push handle 6.2 is horizontally arranged at the bottom of the horizontal slider 6.6.
[0086] A horizontally extending feeding channel is provided on the first mounting seat 6.5, and the second pusher 6.2 is a horizontal push plate that moves back and forth horizontally along the feeding channel. The bottom of the first mounting seat 6.5 has a magnetic steel inlet corresponding to the magnetic steel inlet and outlet 5.5e above and below, ensuring that the magnetic steel and isolation plate in each group of magnetic steel enter the feeding channel through the magnetic steel inlet.
[0087] During operation, the second motor 6.7a drives the second pusher 6.2 to move back and forth horizontally along the feeding channel through the synchronous belt transmission pair, the second lead screw 6.7b and the horizontal slider 6.6. The outward stroke of the second pusher 6.2 pushes the magnet to move toward the magnet patch mechanism 7. During this process, the right end of the second pusher 6.2 can extend out of the feeding channel and push the magnet into the limiting groove 7.1 of the magnet patch mechanism 7, thereby realizing automatic feeding of the magnet; during the return stroke of the second pusher 6.2, it pushes the isolation plate to move toward the recovery component to realize the recovery of the isolation plate.
[0088] like Figure 10 As shown, the second lead screw 6.7b is rotatably arranged on the first mounting seat 6.5 through a plurality of second connecting seats 6.7c; a pair of second guide columns 6.7d are horizontally arranged on the second connecting seat 6.7c, and the horizontal slider 6.6 has a through-hole that cooperates with the second guide column 6.7d. The horizontal slider 6.6 is inserted into the second guide column 6.7d through the through-hole, effectively ensuring the movement trajectory of the second push handle 6.2.
[0089] like Figure 6 As shown, the recycling component has a vertically arranged recycling box 6.8, the top of the recycling box 6.8 is connected to the other end of the feeding channel. When the second pusher 6.2 pushes the magnetic steel, the first pusher 6.1 pushes the isolation sheet into the feeding channel, and the second pusher 6.2 pushes the isolation sheet to make it fall into the recycling box 6.8, realizing the automatic recycling of the isolation sheet and the automatic feeding of the magnetic steel, and the structure is ingenious.
[0090] During actual installation, a box body is installed at the bottom of the recovery box 6.8. By replacing the box body, the isolation sheet can be recovered in time without stopping the machine, thereby improving assembly efficiency.
[0091] like Figure 12-13 As shown, the magnetic steel patch mechanism 7 includes a second support 7.1 provided on the operating table 1.1, a lifting slide 7.2 driven by a fourth linear power source, and a second mounting base 7.3 fixed to the lifting slide 7.2. The second mounting base 7.3 is provided with an adsorption and separation mechanism for adsorbing the magnetic steel. Specifically:
[0092] like Figure 13 As shown, the fourth linear power source includes a third motor 7.4a mounted on the second support 7.1 and a third lead screw drivingly connected to the third motor 7.4a. The lifting platform 7.2 is threadedly connected to the third lead screw. During operation, the third motor 7.4a drives the lifting platform 7.2 and the second mounting base 7.3 to rise and fall synchronously via the third lead screw, achieving automatic placement and resetting of the magnets.
[0093] like Figure 2 and Figure 13-15As shown, a guide rail 7.5 corresponding to the feeding channel is provided at the bottom of the second mounting seat 7.3. The channel of the guide rail 7.5 is consistent in height with the feeding channel and is docked with the feeding channel. The second push handle 6.2 can pass through the guide rail 7.5 to clamp the magnetic steel into the limiting groove 7.1 at the bottom of the second mounting seat 7.3. The structure is ingenious.
[0094] like Figure 13 As shown, a pair of first slide rails 7.4c are vertically arranged on the second support 7.1, and a slider 7.4d is arranged on the rear side of the lifting slide 7.2, which moves up and down along the first slide rails 7.4c, effectively ensuring the stability and movement trajectory of the lifting slide 7.2 and avoiding the lifting slide 7.2 from deflecting during operation.
[0095] like Figure 13 As shown, the magnetic patch mechanism 7 also includes a reset mechanism for resetting the lift slide 7.2. This reset mechanism comprises a stopper 7.6a fixed to one side of the lift slide 7.2 and a third guide post 7.6b that slides through the stopper 7.6a. A pressure block 7.6c (nylon block) is located on top of the third guide post 7.6b. A reset spring is mounted on the third guide post 7.6b between the stopper 7.6a and the pressure block 7.6c. After patch placement, the pressure block presses against the rotor to prevent it from being lifted by the magnets during the patching process.
[0096] like Figure 14-17 As shown, the adsorption and separation mechanism includes a separation block 7.7 (made of nylon or other non-magnetic material) driven by a fifth linear power source and moving back and forth horizontally along the inner cavity of the second mounting seat 7.3. A magnet 7.8 for adsorbing the magnetic steel is provided in the mounting hole at one end of the separation block 7.7; the fifth linear power source is a second cylinder 7.9a provided on the second mounting seat 7.3, and a vertically arranged connecting block 7.9b is fixed to the piston rod of the second cylinder 7.9a. The separation block 7.7 is fixed to the bottom of the connecting block 7.9b and moves back and forth in the inner cavity of the second mounting seat 7.3. The separation block 7.7 is located above the guide rail 7.5 to ensure that the magnetic steel can enter the limit groove 7.1 from the guide rail 7.5.
[0097] During operation, when the second pusher 6.2 pushes the magnet into the limiting groove 7.1, the second cylinder 7.9a drives the separation block 7.7 to move in the direction of the limiting groove 7.1 through the connecting block 7.9b, so that the magnet 7.8 on the separation block 7.7 corresponds to the magnet up and down, and the magnet 7.8 absorbs the magnet to prevent the magnet from falling off; after the magnet is in place, the third motor 7.4a works to drive the lifting slide 7.2 and the second mounting seat 7.3 to descend at the same time, and the limiting groove 7.1 corresponds to the assembly slot of the rotor up and down, and then the magnet is pressed into the assembly slot. Before assembly, the second cylinder 7.9a drives the separation block 7.7 to move in the direction of the feeding channel to separate the magnet and the magnet 7.8, so as to prevent the magnet 7.8 from adsorbing the magnet again when the second mounting seat 7.3 is reset.
[0098] like Figure 18 As shown, the rotor fixing mechanism 4 includes a mounting platform 4.1 driven by a sixth linear power source, the sixth linear power source includes a fourth motor 4.2a and a fourth lead screw driven by the fourth motor 4.2a (of course, the sixth linear power source can also be a cylinder or a hydraulic cylinder), and a nut seat 4.2b that cooperates with the fourth lead screw thread is installed at the bottom of the mounting platform 4.1. The fourth motor 4.2a drives the mounting platform 4.1 and the positioning and tensioning structure to move back and forth through the nut seat 4.2b, which is convenient for taking and placing the rotor.
[0099] like Figure 18 As shown, the magnetic steel assembly station of the operating table 1.1 has a rectangular mounting hole. A pair of second slide rails 4.2c extending forward and backward are provided on the operating table 1.1 on the left and right sides of the mounting hole. Strip sliders 4.2d that cooperate with the second slide rails 4.2c are provided on the left and right sides of the bottom surface of the mounting table 4.1. The strip sliders 4.2d move back and forth along the second slide rails 4.2c to ensure smooth movement of the mounting table 4.1 and the positioning and tensioning structure.
[0100] like Figure 18-20 As shown, the rotor fixing mechanism 4 also includes a base 4.4 disposed below the mounting platform 4.1. The base 4.4 is secured to the mounting platform 4.1 via columns. A rotating base 4.5 driven by a second power mechanism is disposed between the base 4.4 and the mounting platform 4.1. The rotating base 4.5 is secured to the positioning and tensioning structure. The second power mechanism is a second divider 4.6 disposed below the mounting platform. The rotating base 4.5 is secured to the motor shaft of the second divider 4.6. The second divider 4.6 drives the rotating base 4.5 to rotate, thereby rotating the positioning and tensioning structure.
[0101] like Figure 19-20 As shown, the positioning and tensioning structure includes a cylinder 4.7a fixed to the rotating base 4.5 and a seventh linear power source disposed within the cylinder 4.7a. The seventh linear power source is a vertically arranged cylinder (i.e., a third cylinder 4.7b). The cylinder 4.7a extends upwardly through the mounting platform 4.1 and rotates in conjunction with the mounting platform 4.1. A vertically extending positioning ejector pin 4.7c is fixedly connected to the piston rod of the third cylinder 4.7b. A claw assembly is provided on the top of the positioning ejector pin 4.7c.
[0102] like Figure 19-23As shown, the claw assembly has a plurality of radially arranged claws 4.7d, which are connected end to end to form a locking head with a columnar structure. The plurality of claws 4.7d are connected end to end to form a tapered hole that cooperates with the tapered head of the positioning ejector pin 4.7c, and the positioning ejector pin 4.7c is inserted into the tapered hole. When the piston rod of the third cylinder 4.7b extends upward, the claws 4.7d are horizontally opened along the guide groove 4.7h described later through the tapered hole, and the locking head becomes larger and presses against the inner ring of the rotor F, so that the clamping assembly is Figure 22 The closed state shown becomes Figure 23 The tightening state shown in the figure then realizes the fixation of the rotor.
[0103] like Figure 19-22 As shown, the outer wall of each clamping claw 4.7d is also integrally formed with a guide block 4.7f, and the top of the cylinder 4.7a is provided with a limit seat 4.7g connected to it up and down, and the upper surface of the limit seat 4.7g is provided with a guide groove 4.7h corresponding to each guide block 4.7f. When the clamping claw 4.7d is closed and tightened, the clamping claw 4.7d moves in the guide groove 4.7h through the guide block 4.7f.
[0104] like Figure 19-22 As shown, the return assembly includes multiple return springs 4.7i corresponding to the claws 4.7d one by one. The return springs 4.7i are horizontally arranged in the guide groove 4.7h. The outer end of the return spring 4.7i is connected to the outer end of the guide groove 4.7h, and the inner end of the return spring 4.7i is connected to the guide block 4.7f, which is used to fix the claw 4.7d and prevent the positioning pin 4.7c from pushing the claw 4.7d off during the process of moving upward to push open the claw 4.7d.
[0105] During actual installation, the second linear power source, the third linear power source and the fourth linear power source can also be cylinders, motor-driven synchronous belt transmission pairs, or motor-driven chain transmission pairs, etc., which can be flexibly selected according to the installation space and operating conditions.
[0106] The working process and principle of the present invention are briefly described as follows:
[0107] Place each set of magnets (including spacers) horizontally on the fixed clamping block 3.4. Start the first cylinder 3.2, which pushes the movable clamping block 3.6 toward the fixed clamping block 3.4. Use the correction slots 3.7 and the magnet correction slots 3.9 to align each set of magnets. Repeat this process to complete the correction of multiple sets of magnets.
[0108] Place the calibrated multiple sets of magnetic steel from the magnetic steel inlet and outlet 5.5e on the upper limit plate 5.5a from top to bottom into each magnetic steel inlet and outlet channel 5.1 of one magnetic steel storage fixture 5; repeat this operation and place the calibrated multiple sets of magnetic steel from bottom to bottom into each magnetic steel inlet and outlet channel 5.1 of the other magnetic steel storage fixture 5;
[0109] The fourth motor 4.2a drives the mounting platform 4.1 and the positioning and tensioning structure to move forward synchronously. The rotor is placed on the claw assembly using a robotic arm. The piston rod of the third cylinder 4.7b extends upward. The third cylinder 4.7b uses the positioning ejector pin 4.7c to push the multiple claws 4.7d open to form a cylindrical structure, thereby tightening the rotor and securing it. After the rotor is secured, the mounting platform 4.1 and the positioning and tensioning structure are reset.
[0110] The magnetic steel inlet and outlet channel 5.1 is located at the material retrieving station corresponding to the first pusher 6.1. The first pusher 6.1 pushes the magnetic steel upward from the bottom of the magnetic steel inlet and outlet channel 6.1. The magnetic steel at the top enters the feeding channel from the magnetic steel inlet and outlet 5.5e of the upper limit plate 5.5a. The second motor 6.7a drives the second pusher 6.2 to move along the feeding channel toward the guide rail 7.5 through the horizontal slider 6.6. The guide rail 7.5 is docked with the feeding channel. The second pusher 6.2 can directly push the magnetic steel into the limit groove 7.1 through the guide rail 7.5. The second cylinder 7.9a drives the separation block 7.7 to move so that its magnet is located in the limit groove 7.1, thereby adsorbing the magnetic steel stuck in the limit groove 7.1.
[0111] The first pusher 6.1 pushes the isolation sheet into the feeding channel, and the second pusher 6.2 pushes the magnet into place and then returns. During the return process, the isolation sheet is pushed into the recycling box 6.8 to achieve timely processing of the isolation sheet and facilitate the pushing of the next magnet, thus realizing automatic feeding of the magnet;
[0112] When the magnet is clamped in the limiting groove 7.1, the third motor 7.4a of the magnet patch mechanism 7 drives the lifting slide 7.2 and the second mounting seat 7.3 to descend synchronously. At the same time, the second cylinder 7.9a drives the separation block 7.7 to return to the direction of the feeding channel to separate the magnet 7.8 from the magnet, ensuring that the magnet patch mechanism 7 presses the magnet in the limiting groove 7.1 into the assembly groove of the rotor;
[0113] During the magnetic steel assembly process, the positioning and tensioning structure is rotated while assembling, and the rotor is driven to rotate by the positioning and tensioning structure, thereby realizing the continuous assembly of the magnetic steel on the rotor;
[0114] After the assembly is completed, the piston rod of the third cylinder 4.7b retracts and closes the six claws 4.7d. The diameter of the column surrounded by the claws 4.7d becomes smaller, thereby releasing the rotor. The fourth motor 4.2a drives the mounting platform 4.1 to move forward. The robotic arm grabs the assembled rotor and places it at the designated position. It then grabs another rotor to be assembled on the claw assembly and repeats the operation to achieve efficient assembly of the magnets on the other rotor.
