Description

Technical Field

[0001] The invention relates to the field of assembly of a flywheel energy storage system, and in particular to an automatic assembly method of a flywheel used in a flywheel energy storage system. Background Art

[0002] The flywheel energy storage system uses physical methods to store energy, and realizes the mutual conversion and storage between electric energy and the mechanical kinetic energy of the high-speed running flywheel through the electric / generating reciprocal bidirectional motor. The flywheel energy storage system has the advantages of high energy density, high conversion rate of electric energy and mechanical energy, fast charging speed, maintenance-free, low-carbon and environmentally friendly, and has been applied in aerospace, power grid peak regulation and wind power generation.

[0003] The flywheel energy storage battery (i.e., the flywheel body) is the core part of the flywheel energy storage system, including a flywheel container with an upper cover plate and a lower cover plate, a flywheel installed in the flywheel container, alternately arranged rotors (including motor rotors) and gaskets (multiple rotors and gaskets), and a point armature disk fixed in the container, etc. In order to realize the magnetic suspension of the flywheel, the upper surface of the flywheel is equipped with motor magnets, and the lower surface of the flywheel is equipped with suspension magnets. The flywheel can be rotated at high speed (speed above 7200rpm) in the flywheel container through magnetic suspension technology to realize energy storage and energy conversion.

[0004] The assembly of the magnet and the main shaft on the flywheel is an important step in the assembly of the flywheel body. First, the suspension magnet and the motor magnet are respectively assembled on the surface of the flywheel (this process requires turning the flywheel over), and then the main shaft is pressed into the inner hole of the flywheel. Finally, the flywheel is turned upside down 180° and hoisted in the flywheel container to complete the assembly of the flywheel. The specific defects of the existing assembly method are as follows:

[0005] Firstly, the assembly of flywheel motor magnets and suspension magnets is mostly done manually. During assembly, a buffer tie is first placed in the slot of the flywheel to prevent the magnet from adsorbing to the flywheel. After the magnet is placed in the slot, the buffer tie is slowly removed from the side manually, resulting in low patch efficiency. In addition, it is difficult to control the force of the tie when patching, and the magnet is easily broken, which increases costs and further reduces patch efficiency. Furthermore, the entire patch process requires manual material removal and patching, which is inefficient. In addition, since the magnets leaving the factory are separated by non-magnetic separators, the separators need to be removed when removing the materials, further reducing the efficiency of material removal.

[0006] Secondly, during the flywheel assembly process, since magnetic steel needs to be assembled on both surfaces of the flywheel, flywheel flipping is an essential part of the flywheel body assembly operation. Due to the high volume density of the flywheel and its disc-shaped structure, it is difficult to grasp during the flipping process, and the flipping is difficult. The disc parts are prone to fall off during the flipping process, posing a safety hazard. In addition, the spindle is prone to fall off when flipping the flywheel and the spindle, which means that secondary press fitting is required, affecting the assembly efficiency.

[0007] Furthermore, the assembly of the flywheel and the main shaft is mainly done by manual pressing, which requires continuous correction and measurement by humans, alignment on the inside of the flywheel part hole, and manual pushing of the main shaft into the flywheel hole slowly from above. The whole process is very inefficient and can easily cause damage to the flywheel inner hole and the main shaft. At the same time, if the assembly process is not well controlled, personal injury can easily occur. Summary of the invention

[0078] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0079] The core purpose of the present invention is to provide an automatic assembly method for a flywheel and a flywheel container, thereby realizing the automatic assembly of the flywheel and the flywheel container, improving the assembly efficiency and saving manpower.

[0080] Combination Figure 1 It can be seen that the automatic assembly method of the flywheel and the flywheel container of the present invention comprises the following steps: the first step is to position and install the flywheel on the first bearing seat 106.3 driven by the first rotating mechanism so that the first surface of the flywheel faces upward, and to position and install the first magnetic steel (i.e., the motor magnetic steel) in the magnetic steel slot of the first surface by using the first magnetic steel patch device 10; wherein:

[0081] The first rotating mechanism can realize the rotation of the flywheel by driving the first bearing seat 106.3 to rotate. When mounting the magnet, the flywheel can be rotated at a set frequency so that the empty magnetic steel slot is always located below the first magnetic steel mounting device 10, thereby realizing continuous mounting of the motor magnetic steel and improving the mounting efficiency.

[0082] In the second step, after the motor magnets are assembled, the flywheel with the motor magnets attached is placed in the clamping space of the flipping device 20. The clamping mechanism of the flipping device 20 clamps the flywheel and flips it 180° so that the second side of the flywheel faces upward. The flipped flywheel is then placed on the second bearing seat driven by the second rotating mechanism, and the suspension magnet is positioned and installed on the second side using the second magnet patch device 30.

[0083] During the patch process, the second rotating mechanism can realize the rotation of the flywheel by driving the second bearing seat to rotate. During the patch process, the flywheel can be rotated at a set frequency so that the empty magnetic steel slot is always located below the second magnetic steel patch device 30, thereby realizing the automatic continuous patch of the suspended magnetic steel and improving the patch efficiency.

[0084] The third step is to position and install the flywheel with the first magnetic steel and the second magnetic steel attached thereto on the third bearing seat of the spindle press-fitting device 40, and to press-fit the spindle into the inner hole of the flywheel using the spindle press-fitting device 40;

[0085] The fourth step is to place the flywheel in the clamping space of the flipping device 20 after the spindle is pressed into place, and use the flipping device 20 to flip the flywheel and the spindle 180° synchronously again so that the first side of the flywheel faces upward (that is, the motor magnet is located on top); the flipped flywheel and spindle are hoisted into the flywheel container to complete the hoisting operation of the flywheel in the flywheel container, thereby realizing the automatic assembly of the flywheel.

[0086] The present invention proposes for the first time a flywheel and flywheel container assembly line based on a first magnetic steel patch device 10, a second magnetic steel patch device 30, a flywheel flipping device 20 and a spindle pressing device 40. It is also the first automatic assembly line in China with less manual intervention and a high degree of automation. It lays the foundation for realizing the automatic assembly of the flywheel body and improves the production efficiency of the flywheel body.

[0087] Combination Figure 2-11 It can be seen that the first magnetic steel patch device 10 in the present invention comprises a first frame 101, on which a first magnetic steel material storage mechanism 102, a first material taking mechanism 103, a first material feeding mechanism 104, a first patch mechanism 105 and a first flywheel positioning mechanism 106 are arranged in sequence;

[0088] The first bearing seat 106.3 of the first flywheel positioning mechanism 106 is located below the first patch mechanism 105 to achieve the positioning and installation of the flywheel. During operation, the motor magnets are stored in the first storage tank 102.2, and each group of motor magnets can be taken out one by one and transmitted to the first feeding mechanism 104 by the first material taking mechanism 103. The first feeding mechanism 104 can push the motor magnets to the first patch mechanism 105 in a relay manner, and the magnets are automatically pasted in the card slot of the flywheel by the first patch mechanism 105, so as to realize the automatic loading, feeding and patching of the flywheel motor magnets, and improve the assembly efficiency of the flywheel and the motor magnets.

[0089] Combination Figure 3-4It can be seen that the first magnetic steel storage mechanism 102 includes a first storage rack 102.1 driven by a third rotating mechanism, and the first storage rack 102.1 (arranged in the first frame) has eight first storage slots 102.2 evenly spaced in an annular direction (of course, the number of the first storage slots 102.2 can also be four, six, etc.), and each first storage slot 102.2 can store a group of magnetic steel (each group of magnetic steel includes magnetic steel and separators assembled alternately); the third rotating mechanism is arranged below the first storage rack 102.1, and the third rotating mechanism is preferably a first indexing mechanism 102.4 driven by a first motor reducer 102.3, and the first storage rack 102.1 is installed on the first indexing mechanism 102.4. When working, the first motor reducer 102.3 drives the first storage rack 102.1 to rotate through the first indexing mechanism 102.4, so that the first storage slots 102.2 on the first storage rack 102.1 rotate to the first material picking mechanism 103 in sequence.

[0090] Combination Figure 2 and 5 It can be seen that the first material picking mechanism 103 is arranged on the first frame and is located below the first feeding mechanism 104. The location of the first material picking mechanism 103 is the material picking station. The first material picking mechanism 103 includes a first mounting seat (fixed on the first frame) vertically arranged on the first frame 101, a power mechanism A1 arranged on the first mounting seat, and a first material picking pusher 103.2 driven up and down by the power mechanism A1; since the pushing stroke of the material picking push is relatively large, the power mechanism A1 preferably has a first lead screw 103.4 that is transmission-connected to the second motor 103.3 (preferably a servo motor), and the first lead screw 103.4 is rotationally arranged on the vertical first mounting seat 103.1 through a bearing seat, and has a compact structure and occupies a small space;

[0091] A first nut seat 103.5 is threadedly connected to the first screw 103.4, and the first material picking handle 103.2 has a connecting portion 103.2a fixed on the first nut seat 103.5 and a vertically arranged pushing portion 103.2b, the pushing portion 103.2b and the connecting portion 103.2a have an inner corner and an outer corner, the inner corner is a right angle and the outer corner is an obtuse angle, so that the first material picking handle 103.2 has an avoidance effect, which is convenient for entering and exiting the first storage trough 102.2.

[0092] Combination Figure 5 It can be seen that the first mounting seat 103.1 also has a pair of guide rails 103.6 parallel to the first lead screw 103.4, and the first nut seat 103.5 is slidably mounted on the two guide rails 103.6, thereby improving the movement accuracy and stability of the first material picking pusher 103.2.

[0093] Combination Figure 2-3 and Figure 6It can be seen that the first feeding mechanism 104 is horizontally mounted above the first magnetic steel storage mechanism 102 and the first material taking mechanism 103. The first feeding mechanism 104 includes a horizontally arranged first feeding slide 104.1 and a first feeding pusher 104.2 driven by a power mechanism A2. The first feeding pusher 104.2 is a plate-like structure slidably arranged in a guide groove of the first feeding slide 104.1. The first feeding slide 104.1 has a guiding function. The first feeding pusher 104.2 adopts a plate-like structure and is located in the first feeding slide 104.1 to ensure the movement accuracy of the first feeding pusher 104.2.

[0094] A first inlet is provided at the bottom of the first feeding chute 104.1 corresponding to the upper and lower positions of the first material picking pusher 103.2, so that the magnet enters the first feeding chute 104.1 from the top of the first material storage trough 102.2; both ends of the first feeding chute 104.1 are opened, one port is connected to the first patch mechanism 105, so as to push the magnet to the first patch mechanism 105; the other port is connected to the recycling box, so that the non-magnetic separator falls into the recycling box, thereby realizing the pushing of the magnet and the automatic recovery of the separator.

[0095] Due to installation space limitations, the power mechanism A2 preferably comprises a synchronous belt transmission mechanism A2 and a second screw 104.3 driven by the synchronous belt transmission mechanism A2. The first feeding pusher 104.2 is fixedly connected to the connecting seat 104.4 on the second screw 104.3 to realize the transmission connection between the first feeding pusher 104.2 and the power mechanism A2.

[0096] Since the first inlet is located at the bottom of the first feeding chute 104.1 and both ends of the first feeding chute 104.1 are opened, the first feeding pusher 104.2 pushes the magnets to the corresponding end of the first patch mechanism 105 during the horizontal reciprocating process, and pushes the separators to the first recycling box F at one end of the first feeding mechanism 104, thereby realizing automatic feeding of the magnets and automatic recycling of the separators.

[0097] In order to ensure the movement accuracy and stability of the first feeding pusher 104.2, the first feeding mechanism also has a guide shaft 104.5 for guiding the connecting seat 104.4, which effectively ensures the accuracy of the first feeding pusher 104.2.

[0098] Combination Figure 2-3 and Figure 7-9It can be seen that the first patch mechanism 105 has a first lifting seat 105.1 driven by a power mechanism A3, a second moving seat 105.2 driven by a power mechanism A4, and two first patch units 105.3 slidably arranged on the second moving seat 105.2. The power mechanism A3 is preferably a third lead screw 105.4 driven by a synchronous belt transmission mechanism A3, and the nut seat on the third lead screw 105.4 is fixedly connected with the first lifting seat 105.1 to realize the overall lifting of the first patch unit 105.3, ensuring that the first feeding mechanism 104 pushes the magnetic steel into the contoured groove at the bottom of the first patch unit 105.3.

[0099] The power mechanism A4 is arranged on one side of the first lifting seat 105.1, including a horizontally arranged first cylinder 105.6. The piston rod of the first cylinder 105.6 is fixedly connected to the second movable seat 105.2. The extension and retraction of the piston rod of the first cylinder 105.6 can drive the second movable seat 105.2 to move back and forth horizontally along the slide rail on the first lifting seat 105.1, thereby realizing the adjustment of the positions of the two first patch units 105.3 to meet the patch requirements of the N-pole and S-pole motor magnets (one of the first patch units 105.3 is used for the N-pole magnet, and the other is used for the S-pole magnet).

[0100] like Figure 7-9 As shown, the first patch unit 105.3 includes a first patch seat 105.3a that is relatively lifted along the second moving seat 105.2, the top of the first patch seat 105.3a is connected to the second cylinder 105.5 on the second moving seat 105.2, and a connecting slide 105.3b that is connected to the first feeding slide 104.1 is provided on the lower surface of the bottom plate of the first patch seat 105.3a, and the end of the connecting slide 105.3b is a contoured groove (i.e., a fan-shaped structure) that is the same as the magnetic steel structure;

[0101] A first anti-falling unit that prevents the magnet from falling off is arranged on the bottom plate of the first patch seat 105.3a, and the first anti-falling unit includes a magnet block 105.3d driven back and forth by the third cylinder 105.3c, and the magnet block 105.3d is located in a slideway inside the bottom plate, and when the magnet block 105.3d is located above the profiling groove, the magnet can be adsorbed in the profiling groove to prevent it from falling off; when patching, the magnet block 105.3d moves in the bottom plate and drives away from the profiling groove to achieve demagnetization, so that the magnet in the profiling groove is attached to the card slot of the flywheel.

[0102] Combination Figure 2-3 and Figure 10-11It can be seen that the first flywheel positioning mechanism 106 is arranged on the workbench of the first frame 101, and includes a first mobile frame 106.1 driven by a power mechanism A5 (preferably a fourth screw 106.7 driven by a servo motor); the first rotating mechanism includes a rotating power source 106.2 arranged on the first mobile frame 106.1 and a first bearing seat 106.3 driven by the rotating power source 106.2, which is rotatably arranged relative to the first mobile seat 106.4, and is used to support a flywheel weighing more than 500kg to ensure the stability of the flywheel. A first rotating seat 106.5 is rotatably arranged in the first mobile seat 106.4, and a first floating adjustment structure is arranged between the first rotating seat 106.5 and the first bearing seat 106.3, which has a buffering effect and realizes the adjustment of the first bearing seat 106.3 in the horizontal direction, thereby realizing automatic centering of the flywheel. Specifically:

[0103] like Figure 10-11 As shown, the first floating adjustment structure includes a first slide rail 106.6a horizontally arranged on the first rotating seat 106.5, a first sliding seat 106.6b sliding along the first slide rail 106.6a and a second slide rail 106.6c horizontally arranged on the first sliding seat 106.6b, the first bearing seat 106.3 is slidably arranged on the second slide rail 106.6c, and the installation directions of the first slide rail 106.6a and the second slide rail 106.6c are perpendicular to each other, so that the first bearing seat 106.3 can be flexibly adjusted in the horizontal direction; the first floating adjustment structure also includes a first limiting unit for limiting the moving position of the first sliding seat 106.6b and a second limiting unit for limiting the moving position of the first bearing seat 106.3, and the structures of the first limiting unit and the second limiting unit are the same. Take the structure of the second limiting unit as an example: the second limiting unit includes a horizontally arranged limiting shaft 106.6d, a fixed seat 106.6e and a limiting spring 106.7d (preferably a compression spring), the limiting shaft 106.6d is slidably passed through the fixed seat 106.6e and its other end is against the first bearing seat 106.3, and the compression spring is sleeved on the limiting shaft.

[0104] During actual assembly, the flywheel weighs more than 500 kg and has a large inertia. The first floating adjustment structure can withstand the inertia of the flywheel. When placing the flywheel, the first bearing seat 106.3 is forced to move left and right and / or forward and backward within a horizontal range. The four limit units can limit the first bearing seat 106.3, so that the first bearing seat 106.3 is automatically centered, effectively ensuring the placement accuracy of the flywheel.

[0105] During actual installation, since the flywheel is heavy, higher stability requirements are placed on the first bearing seat 106.3. The first rotating mechanism of the present invention preferably has a synchronous belt drive mechanism or a chain drive mechanism with a reduction ratio, in which a large-diameter pulley or gear is fixedly connected to the first rotating seat 106.5.

[0106] During actual installation, a tensioning mechanism for tensioning the flywheel is provided in the first bearing seat 106.3 (i.e., the utility model authorized patent with publication number CN215968802U proposed by the applicant in October 2021). The tensioning mechanism is used to tension the flywheel to ensure the stability of the flywheel.

[0107] In the present invention, the second magnetic steel patch device 30 can realize the automatic connection patching of the suspended magnetic steel on the second surface of the flywheel, thereby improving the automatic patching efficiency of the suspended magnetic steel on the flywheel.

[0108] Combination Figure 12-17 It can be seen that the second magnetic steel patch device 30 includes a second frame 301, a second magnetic steel storage mechanism 302, a second material taking mechanism 303, a second feeding mechanism 304, a second patch mechanism 305 and a second flywheel positioning mechanism 306 arranged in the second frame 301. When working, the flywheel suspension magnetic steel is stored in the second magnetic steel storage mechanism 302, and the suspension magnetic steel is pushed into the second feeding mechanism 304 one by one by the second material taking mechanism 303, and the suspension magnetic steel is pushed into the second patch mechanism 305 by the second feeding mechanism 304, and then the suspension magnetic steel is pasted one by one on the flywheel on the second flywheel positioning mechanism 306 by the second patch mechanism 305, so as to realize the automatic patching of the suspension magnetic steel.

[0109] During actual installation, the structure of the second flywheel positioning mechanism 306 is the same as the structure of the first flywheel positioning mechanism 106 of the first magnetic steel patch device 20 to achieve support and tensioning fixation of the flywheel.

[0110] Combination Figure 12-13 It can be seen that the second magnetic steel storage mechanism 302 includes a fourth rotating mechanism 302.3 (a motor reducer and a cam indexing mechanism connected in transmission, with good load-bearing performance) arranged in the second frame 301 and a second storage rack 302.1 driven by the fourth rotating mechanism 302.3, and the second storage rack 302.1 has two storage units for storing magnetic steel, and each storage unit has three second storage troughs 302.2 for storing suspended magnetic steel, which are used to store three different specifications of suspended magnetic steel; the two storage units are arranged relative to each other, laying the foundation for realizing continuous feeding.

[0111] Of course, the fourth rotating mechanism 302.3 may also use only a motor, or may be replaced by a motor and a reducer with a transmission connection, or may use a gear transmission mechanism, a belt transmission mechanism, or other power mechanism that can realize the rotation of the second storage rack 302.1. The present invention is not limited to a motor reducer and a cam dividing mechanism.

[0112] Combination Fig.13It can be seen that the second storage slots 302.2 are opened to facilitate the storage and retrieval of magnetic steel and to facilitate the entry and exit of magnetic steel; the top plate of the second storage rack 302.1 corresponding to each second storage slot 302.2 is provided with a contour marking groove 302.4 consistent with the structure and specifications of the second magnetic steel, so as to realize the rapid storage of second magnetic steels of different specifications and avoid storage errors.

[0113] Combination Fig.13 It can be seen that a recovery container (i.e., an upper-open second recovery box 302.5) for recovering separators (the separators are separator blocks made of non-magnetic materials (such as nylon or rubber, etc.) to avoid strong magnetic adsorption between magnetic steel sheets) is also provided between the two storage units, and the second recovery box 302.5 is provided between the two storage units; one end of the second feeding slide 304.1 is docked with the patch slot of the second patch unit 305.5, and the other end of the second feeding slide 304.1 is located above the second recovery box 302.5, and the second feeding pusher 304.2 can be used to push the separator block into the second recovery box 302.5, so as to realize automatic recovery of the separator block without manual assistance.

[0114] Combination Fig.12 and 14 It can be seen that the second material picking mechanism 303 is arranged on the second frame 301 on the side of the second magnetic steel storage mechanism 302, and it has three second material picking pushers 303.1 that push the three different specifications of suspended magnetic steel in the storage unit upward at the same time, that is, each second material storage slot 302.2 has a second material picking pusher 303.1, and each group of suspended magnetic steel is raised by the second material picking pusher 303.1.

[0115] The second material taking mechanism 303 has a first lifting mechanism, which preferably has a motor and a fifth lead screw 303.2 in transmission connection, and the nut seat on the fifth lead screw 303.2 is threadedly matched with the lifting platform 303.3, thereby realizing the rise and fall of the lifting platform 303.3. Of course, during actual installation, according to the installation space and equipment layout, the first lifting mechanism can also directly use a cylinder, a hydraulic cylinder, a synchronous belt transmission mechanism, or a synchronous belt transmission mechanism and a lead screw.

[0116] A second material picking pusher 303.1 is fixedly connected to the middle of the lifting platform 303.3; linear power sources (i.e., slide cylinders 303.4) are correspondingly arranged on both sides of the lifting platform 303.3, and a sliding block is slidably arranged on the sliding platform of each slide cylinder 303.4, and the second material picking pusher 303.1 is fixed on the sliding block. The second material picking pushers 303.1 on both sides can move back and forth horizontally under the action of the slide cylinder 303.4 to adjust the pushing position, thereby meeting the pushing requirements of different magnetic steels.

[0117] like Fig.14As shown, in order to ensure the movement trajectory and accuracy of the second material picking pusher 303.1, a pair of vertically arranged third slide rails 303.6 are provided on the mounting seat 303.5, and a pair of sliders cooperating with the third slide rails 303.6 are fixedly connected to the lifting platform 303.3. The sliders are clamped on the third slide rails 303.6 and move up and down along the third slide rails 303.6.

[0118] During operation, the material storage unit rotates to the top of the second material picking handle 303.1, so that the second material picking handle 303.1 and the second material storage trough correspond to each other up and down, and the middle second material picking handle 303.1 is located directly below the second material storage trough, and the slide cylinder 303.4 drives the second material picking handles 303.1 on both sides to move a preset distance toward the second material storage trough, so that the second material picking handles 303.1 on both sides are located just below the second material storage trough, ensuring that the second material picking handles 303.1 act on the center position of the magnet, achieving a smooth rise of each group of magnets, and avoiding the magnets from tilting and rising due to unbalanced force.

[0119] like Fig.12 and 15 As shown, the second feeding mechanism 304 is mounted above the second picking mechanism 303, including a third mounting seat 304.7 mounted on the second frame 301 and a power mechanism A6 (preferably a sixth lead screw 304.3 driven by a synchronous belt transmission mechanism) for driving the second feeding pusher 304.2 to move back and forth horizontally, three second feeding slides 304.1 are arranged at intervals on the third mounting seat 304.7, and the moving block 304.4 on the sixth lead screw 304.3 is horizontally arranged above the second feeding slide 304.1 and three second feeding pushers 304.2 are arranged at intervals. The moving block 304.4 is located above the second feeding slide 304.1 to ensure that the second feeding pusher 304.2 moves back and forth along the second feeding slide 304.1.

[0120] like Fig.15 As shown, the bottom of the second feeding chute 304.1 is provided with a second opening 304.1a, and the magnetic steel and separation block in the second storage tank 302.2 can enter the second feeding chute 304.1 through the corresponding openings respectively; both ends of the second feeding chute 304.1 are opened, and one port of each second feeding chute 304.1 is located above the second recovery box 302.5, and the other port of the second feeding chute 304.1 is connected one by one with the second patch unit 305.5. The second feeding pusher 304.2 pushes the suspended magnetic steel to the second patch unit 305.5 of the second patch mechanism 305 on the outward journey, and pushes the separation block to the second recovery box 302.5 on the return journey, which not only realizes the automatic feeding of the suspended magnetic steel, but also realizes the automatic recovery of the separation block, without the need for manual recovery, with a clever structure and a high degree of automation.

[0121] like Fig.15As shown, the second feeding slide 304.1 is a slide rail with a guide groove, and the second feeding pusher 304.2 is a sliding plate 403.11 that moves in the guide groove, thereby ensuring the movement accuracy of the second feeding pusher 304.2; a pair of fixed blocks 304.5 are arranged on the third mounting seat 304.7, and a plurality of guide shafts 304.6 (which are optical axes) parallel to the sixth lead screw 304.3 are arranged between the two fixed blocks 304.5, and the moving block 304.4 is movably arranged on the guide shaft 304.6, thereby effectively ensuring the movement trajectory of the moving block 304.4, and further ensuring the movement accuracy and stable reciprocating movement of the second feeding pusher 304.2.

[0122] like Fig.12 and 16 -17, the second patch mechanism 305 is set above the second flywheel positioning mechanism 306, including a mounting frame 305.1 arranged above the second feeding mechanism 304, and a linear power mechanism (preferably a servo motor 305.2a and a seventh lead screw 305.2b connected in transmission) and a second lifting mechanism (preferably a patch lead screw 305.3 driven by a synchronous belt transmission mechanism B1, and a patch pusher 305.4 for pushing the second patch unit 305.5 up and down) are arranged on the vertical plate of the mounting frame 305.1, and the third moving seat 305.6 is fixedly connected to the seventh nut seat 305.2c on the seventh lead screw 305.2b. When working, the linear power mechanism drives the third moving seat 305.6 to move back and forth horizontally;

[0123] The three second patch units 305.5 (having a second detaching unit, whose structure is the same as that of the first patch unit) are arranged side by side on the third moving seat 305.6 and slide with the third moving seat 305.6. The linear power mechanism adjusts the horizontal position of the three second patch units through the third moving seat.

[0124] The second patch units 305.5 correspond one-to-one to the second feeding chute 304.1, and each second patch unit 305.5 has a patch slot 305.5a corresponding to the second feeding chute 304.1 (with the same structure as the connecting channel of the first patch unit), and the second feeding pusher 304.2 can push the second magnetic steel in the second feeding chute 304.1 directly into the contoured groove at the end of the patch slot.

[0125] In order to ensure the movement accuracy of the third movable seat 305.6, a guide pair consisting of a slide rail and a slider is provided on the vertical plate of the mounting frame 305.1 to ensure the high-precision movement of the third movable seat 305.6.

[0126] During actual installation, the structure of the second patch unit 305.5 is the same as that of the first patch unit. To prevent the magnetic steel from falling, a second anti-falling unit 305.5b is provided on the second patch unit 305.5. The structure of the second anti-falling unit 305.5b is the same as that of the first anti-falling unit, and includes a magnet block driven by a fourth cylinder, which attracts the magnetic steel to prevent it from falling during the descent of the second patch unit 305.5. When the second patch unit 305.5 reaches the second side of the rear flywheel, the magnet block drives away from the suspended magnetic steel, releasing the attraction to the suspended magnetic steel, so as to facilitate pressing the suspended magnetic steel onto the flywheel. Figure 16-17 shown.

[0127] During the actual installation, in order to realize the individual lifting and lowering of each second patch unit 305.5, a row of rollers 305.8 are provided at the bottom of the patch pusher 305.4, and a horizontally arranged guide groove is provided at the upper part of the vertical plate of the second patch unit 305.5. When the roller 305.8 is clamped in the guide groove 305.9 of the second patch unit, the lifting and lowering of the second patch unit 305.5 can be realized through the second lifting mechanism. During operation, since the linear mechanism can drive the three second patch units to move horizontally, each second patch unit 305.5 can be moved to the bottom of the patch pusher 305.4 and cooperate with it, so as to realize the individual lifting and lowering of each second patch unit 305.5, so as to ensure the individual patch, as shown in the specific Figure 15-16 shown.

[0128] In order to ensure the lifting accuracy of each second patch unit 305.5, three rows of guide rails corresponding to the second patch units 305.5 are arranged side by side on the third moving seat 305.6, and each second patch unit 305.5 is provided with a guide block 305.7 with a guide groove corresponding to the guide rail. The guide block 305.7 is clamped on the guide rail to achieve high-precision lifting of the second patch unit 305.5. Figure 15-16 shown.

[0129] The automatic patch process of the second magnetic steel patch device is as follows: first, the suspended magnetic steel is stored in the second material storage slot 302.2 of each material storage unit; the six-axis robot mounts the flywheel on the second flywheel positioning mechanism 306, and uses the second flywheel positioning mechanism 306 to tighten and fix the flywheel; the fourth rotating mechanism 302.3 drives the second material storage rack 302.1 to rotate 180°, so that one group of the second material storage slots 302.2 is located above the second material picking handle 303.1 of the second material picking mechanism 303, and the slide cylinder 303.4 drives the second material picking handle 303.1 to move so that the second material picking handle 303.1 is located directly below each second material storage slot 302.2;

[0130] The first lifting mechanism works, and drives the three second material-taking pushers 303.1 to rise synchronously through the lifting platform 303.3, thereby pushing the three groups of suspension magnets with different specifications to rise synchronously, so that the suspension magnets at the top enter the second feeding slideway 304.1 above one by one; the second feeding mechanism 304 receives the feeding instruction, and the second feeding pusher 304.2 of the second feeding mechanism 304 pushes the three suspension magnets into the contoured grooves in the three second patch units 305.5 corresponding thereto; the second feeding pusher 304.2 pushes the non-magnetic separator block into the recycling box F2 during the return journey, so as to realize the automatic recycling of the separator block;

[0131] When the suspended magnet reaches the profiling groove, the magnet block of the second anti-drop unit 305.5b is located at the corresponding upper and lower positions of the profiling groove to prevent the suspended magnet from falling out of the profiling groove; the second patch unit 305.5 descends to patch, and during this process the magnet block moves away from the top of the profiling groove, so that the suspended magnet is demagnetized and adsorbed on the second side of the flywheel; after the patch is completed, the second patch unit 305.5 is quickly reset and moved horizontally, so that the next second patch unit 305.5 moves to the second feeding pusher 304.2 to realize the automatic patch of the magnetic steel sheet, and the circumferential patch of three types of suspended magnets is repeated in this way; during the continuous patch process, the second flywheel positioning mechanism 306 can drive the flywheel to rotate to adjust the position of the flywheel so that the unpasted part is always located below the second patch unit 305.5.

[0132] Combination Figure 18-20 It can be seen that the turning device 20 of the present invention includes a third frame 201, a turning power source arranged on the third frame 201, and a clamping mechanism driven to turn by the turning power source. Among them: a turning opening is provided on the working table of the third frame 201 to provide a turning space for the clamping mechanism;

[0133] The flipping power source includes a third motor reducer 202.1 fixed on the third frame 201 (of course, it can also be a motor or a motor-driven gear transmission pair with a reduction ratio); the supporting unit includes a pair of transmission shafts 202.2 rotatably arranged on the workbench through a bearing seat, and the output end of the third motor reducer 202.1 is connected to one of the transmission shafts 202.2 to provide power for the flipping of the clamping mechanism.

[0134] like Figure 18-20 As shown, the clamping mechanism includes a flip frame and a clamping structure arranged on the flip frame, the flip frame includes a pair of fixed base plates 203.1 arranged vertically at intervals, and the two fixed base plates 203.1 are connected together by a pair of connecting beams 203.2 and four guide connecting shafts 203.3;

[0135] The clamping structure includes four main clamping components of the same structure, which are mounted on the fixed base plate 203.1 in pairs (i.e., two main clamping components are mounted on each fixed base plate 203.1). Specifically, the main clamping components include a first power source (i.e., the fifth cylinder 204.1, or a linear power source such as a hydraulic cylinder) arranged on the fixed base plate 203.1, a first push plate 204.2 is fixedly connected to the piston rod of the fifth cylinder 204.1, and a first clamping block 204.3 (having a first arc-shaped surface matching the outer periphery of the flywheel) is horizontally fixed on the first push plate 204.2 to achieve circumferential clamping of the flywheel; two pairs of first clamping blocks 204.3 are arranged at intervals up and down to balance the force on the flywheel and ensure the clamping stability of the flywheel.

[0136] In order to further ensure the moving track and clamping force of the first clamping block 204.3, a guide structure is provided between the fixed base plate 203.1 and each first push plate 204.2. Figure 18-20 As shown, the guide structure has two pairs of guide pairs spaced apart in front and back, each pair of guide pairs includes a guide seat 204.5 (i.e., a linear bearing) fixed on the fixed base plate 203.1 and a first guide rod 204.6 penetrating each guide seat 204.5, and one end of the first guide rod 204.6 is fixed on the first push plate 204.2, and the first push plate 204.2 moves back and forth horizontally along the guide seat 204.5 on the fixed base plate 203.1 through the first guide rod 204.6. The guide pair has both a guiding function and a supporting function to ensure that each pair of first clamping blocks 204.3 clamps the flywheel.

[0137] When working, the piston rods of the four fifth cylinders 204.1 extend outward at the same time, and the arc surface of each first clamping block 204.3 is against the outer peripheral surface of the flywheel, thereby realizing the circumferential clamping of the flywheel. During the operation of the fifth cylinder 204.1, the cooperation of each first guide rod 204.6 and the guide seat 204.5 can ensure the accuracy of the first push plate 204.2 and the first clamping block 204.3, so that the first clamping block 204.3 is balanced in force, thereby realizing stable clamping of the flywheel and preventing it from falling.

[0138] Combination Figure 18-20 It can be seen that the clamping structure also includes four auxiliary clamping components with the same structure. Two auxiliary clamping components are installed on each fixed base plate 203.1, and the two auxiliary clamping components are located on the front and rear sides of the first clamping block 204.3, so that the second clamping blocks 205.1 of the four auxiliary clamping components are arranged circumferentially at intervals to improve the clamping stability of the flywheel.

[0139] like Fig.19 , 20As shown, the auxiliary clamping assembly includes a second power source (i.e., the sixth cylinder 205.2), a second push plate 205.3 disposed on the piston rod of the sixth cylinder 205.2, and a second clamping member (i.e., a second clamping block 205.1) disposed vertically on the second push plate 205.3. The second clamping block 205.1 is disposed vertically to achieve radial clamping of the flywheel, further increasing the clamping area, and preventing the flywheel from falling during the flipping process, with high safety. During actual installation, each second push plate 205.3 is provided with a guide linear bearing 205.4 corresponding to the guide connecting shaft 203.3 one by one, to ensure the accuracy of the second push handle and the second clamping block 205.1.

[0140] In addition, a guide pair consisting of a linear bearing and a guide rod is also provided between the second push plate 205.3 and the fixed base plate 203.1 to ensure the movement trajectory of the second push plate 205.3 and the second clamping block 205.1.

[0141] During operation, the flywheel is placed in the clamping structure, and the fifth cylinder 204.1 and the sixth cylinder 205.2 of the clamping structure extend outward at the same time, and the four first clamping blocks and the four second clamping blocks 205.1 act on the flywheel at the same time. The second clamping block 205.1 is a vertical clamping block, and the first clamping block 204.3 is a horizontal clamping block, thereby achieving a tight clamping of the disc to prevent it from falling. After the flywheel is clamped, the flipping power source drives the flywheel to flip through the transmission shaft 202.2, thereby achieving the upside-down flipping of the flywheel, and then flipping the second side of the flywheel to the top.

[0142] In a preferred embodiment of the present invention: Figure 19-20 It can be seen that an anti-slip mechanism 206 for preventing the main shaft from falling off is also provided on the fixed base plate 203.1 of the flipping device 20. The anti-slip mechanism 206 includes a third power source (i.e., the seventh cylinder 206.1) arranged horizontally, a third push plate 206.2 driven by the seventh cylinder 206.1, and an anti-slip member (i.e., an anti-slip block 206.3) fixed on the third push plate 206.2. An anti-slip groove matching the end of the shaft member can be machined on the anti-slip block 206.3, so that the anti-slip block 206.3 is clamped on the upper end of the shaft member. When flipped, the anti-slip groove of the anti-slip block 206.3 opens upward to provide support force for the main shaft, thereby preventing the main shaft from falling off the flywheel, so as to facilitate the flipping of the flywheel with the main shaft pressed on it.

[0143] like Fig.21 As shown, the spindle press-fitting device 40 can press-fit the spindle onto the flywheel with the motor magnet and the suspension magnet attached thereto, and comprises a fourth frame 401, a third lifting mechanism 402, a shaft clamping mechanism 403 and a shaft press-fitting mechanism 404. The fourth frame 401 has a mounting platform 401.1, an upper protective cover (not shown) and a lower protective cover to protect the shaft clamping mechanism 403 and the shaft press-fitting mechanism 404.

[0144] Combination Figure 21-23 It can be seen that the third lifting mechanism 402 has a first lifting unit driven by the power mechanism A8 and a support guide structure arranged on the mounting platform 401.1, and the first lifting unit can be smoothly lifted and lowered along the support guide structure; the support guide structure includes a support frame body and a first guide pair, and the support frame body includes two groups of column units 402.1 vertically arranged on the mounting platform (each group of column units 402.1 has two columns and a pair of first mounting members (i.e., vertically arranged first mounting plates 402.2) arranged oppositely, and each first mounting plate 402.2 is fixed to one of the column units 402.1 through a plurality of connecting supports 402.3 to ensure the load-bearing performance of the entire support frame body to meet the installation requirements of the shaft pressing mechanism 404 and the shaft clamping mechanism 403;

[0145] like Figure 21-23 As shown, the first lifting unit includes a horizontally arranged first lifting member (i.e., a first lifting plate 402.4) and a pair of vertically arranged second lifting members (i.e., second lifting plates 402.5) at the front and rear edges of the first lifting plate 402.4. The second lifting plates 402.5 correspond to the first mounting plates 402.2 one by one. Each second lifting plate 402.5 is lifted and lowered along the corresponding first mounting plate 402.2 through a first guide pair, thereby realizing stable lifting of the first lifting unit.

[0146] In one embodiment of the present invention: Figure 21-23 As shown, the first guide pair includes a fourth slide rail 402.6 vertically arranged on the first mounting plate 402.2 and a fourth slider vertically arranged on the second lifting plate 402.5, and the fourth slider is clamped on the fourth slide rail 402.6 and slidably cooperates with the fourth slide rail 402.6 to ensure the smooth lifting and movement accuracy of the first lifting unit. Of course, in actual installation, the fourth slider can also be installed on the first mounting plate 402.2, and the fourth slide rail 402.6 can be installed on the second limit plate to meet the installation requirements under different installation conditions.

[0147] like Figure 21-23 As shown, the power mechanism A8 includes a power source M arranged below the mounting platform 401.1, an eighth lead screw 402.7 driven to rotate by the power source M, and a nut seat arranged on the eighth lead screw 402.7. The nut seat is rotatably arranged on a mounting support below the mounting platform 401.1. During the rotation of the nut seat, the eighth lead screw 402.7 is lifted and lowered. The top of the eighth lead screw 402.7 is fixed to the first lifting plate 402.4 through the first connecting seat, thereby realizing the fixed connection between the first power mechanism and the first lifting unit, and realizing the stable lifting and lowering of the shaft clamping mechanism and the shaft clamping mechanism 403.

[0148] The power source M includes an eighth motor 402.8 and a gear transmission pair with a reduction ratio driven by the eighth motor 402.8. The passive gear of the gear transmission pair is rotatably arranged on a mounting support. The lower part of the eighth lead screw 402.7 passes through the passive gear. An anti-detachment seat is arranged at the bottom of the eighth lead screw 402.7 to prevent the eighth lead screw 402.7 from detaching from the passive gear. The nut seat is fixed to the upper part of the passive gear and rotates with the passive gear.

[0149] Combination Figure 21-23 It can be seen that the shaft clamping mechanism 403 is mounted above the mounting platform 401.1 and is slidably matched with the supporting guide structure. The first frame of the shaft clamping mechanism 403 is fixedly connected with the first lifting unit. The shaft clamping mechanism 403 has a pair of shaft clamping claws 403.1 driven to open and close by the fifth power source.

In addition, the second floating plate 405.2 is slidably arranged on the upper surface of the first floating plate 405.1, and the first floating plate 405.1 is slidably arranged on the upper surface of the mounting platform 401.1, and the sliding directions of the first floating plate 405.1 and the second floating plate 405.2 are perpendicular, so as to realize the horizontal adjustment of the third bearing seat 405.3;

[0164] A third guide pair is provided between the first floating plate 405.1 and the mounting platform 401.1, and the third guide pair includes an eighth slide rail 405.4 horizontally provided on the mounting platform 401.1 and an eighth slider provided on the lower surface of the first floating plate 405.1, and the first floating plate 405.1 moves horizontally along the eighth slide rail 405.4 through the eighth slider; a fourth guide pair is provided between the first floating plate 405.1 and the second floating plate 405.2, and the fourth guide pair includes a ninth slider horizontally provided on the first floating plate 405.1 and a ninth slider provided on the lower surface of the second floating plate 405.2, and the second floating plate 405.2 moves horizontally along the ninth slide rail 405.5 through the ninth slider; the ninth slide rail 405.5 and the ninth slider are vertically installed, thereby realizing the adjustment of the third bearing seat 405.3 in the left-right direction and the front-back direction. The flywheel floating deviation correction structure 405 realizes the fine adjustment of the third bearing seat 405.3 in the left-right direction and the front-back direction, realizes the automatic centering of the flywheel, and improves the assembly accuracy.

[0165] Combination Figure 30-31 It can be seen that the flywheel floating correction structure 405 also includes four limiting units, and a limiting unit is arranged at both ends of the moving direction of each floating plate. Each limiting unit includes a horizontally arranged limiting rod 405.6 and an elastic member 405.7 (i.e., a compression spring) arranged between the limiting rod 405.6 and the floating plate. One end of the limiting rod 405.6 is pressed against the first floating plate 405.1 or the second floating plate 405.2 to limit the first floating plate 405.1 and the second floating plate 405.2.

[0166] Combination Figure 30-31 It can be seen that the shaft support mechanism 406 includes a guide support assembly mounted below the mounting platform 401.1 and a third lifting member driven to rise and fall by a fourth lifting mechanism, the third lifting member is provided with a support shaft 406.3, and a support seat is fixed on the top of the support shaft 406.3a. Specifically:

[0167] The fourth lifting mechanism comprises a lifting motor 406.1a arranged below the mounting platform 401.1 and a synchronous belt transmission pair driven by the lifting motor 406.1a, two driven pulleys of the synchronous belt transmission pair are penetrated with two vertically arranged ninth lead screws 406.1b, a base 406.1c is arranged below the mounting platform 401.1, and the lower part of the ninth lead screw 406.1b is fixed on the base 406.1c;

[0168] The third lifting member is a third lifting plate 406.1d horizontally arranged between the mounting platform 401.1 and the base 406.1c, and the nut seat on the ninth lead screw 406.1b and the third lifting plate 406.1d are fixedly connected together, thereby realizing the lifting of the third lifting plate 406.1d;

[0169] The guide support assembly includes a vertically arranged guide rod 406.2a (at least two guide rods, preferably four guide rods) and a linear bearing 406.2b arranged on the guide rod. The linear bearing 406.2b is fixed on the third lifting plate 406.1d, so that the third lifting plate 406.1d can be lifted and lowered along the guide rod 406.2a, thereby realizing stable lifting of the third lifting plate 406.1d.

[0170] Since the support shaft 406.3a is vertically arranged on the third lifting plate 406.1d, a support seat 406.4 for supporting the main shaft is arranged on the top of the support shaft 406.3. During assembly, the main shaft pressing mechanism 404 presses the main shaft downward, and the main shaft passes through the mounting hole of the flywheel and its lower part rests on the support seat 406.4. The support seat descends synchronously to ensure the normal progress of the assembly operation.

[0171] The working process of the above spindle press-fitting device is as follows: the flywheel with the motor magnet and the suspension magnet attached is placed on the third bearing seat 405.3, and the flywheel floating correction structure 405 can correct the flywheel so that the flywheel is located at the center of the third bearing seat 405.3; the eighth cylinder 403.5 pushes the shaft clamping structure to move rightward so that the shaft clamping claw 403.1 is located above the flywheel, and the multi-axis robot places the shaft between the two shaft clamping claws 403.1, and the piston rods of the two ninth cylinders 403.9 are retracted at the same time to clamp the shaft;

[0172] After the spindle is clamped, the piston rod of the tenth cylinder 404.5 extends outward, so that the pressing seat 404.1 moves to the top of the spindle; the seventh motor makes the shaft clamping mechanism 403 and the shaft pressing mechanism 404 descend to a preset height, the lower part of the spindle is aligned with the inner hole of the flywheel, and the lower part of the spindle is pressed into the inner hole of the flywheel; then the spindle is released, and the shaft pressing mechanism 404 continues to descend and presses the top of the spindle downward to completely press the spindle into the inner hole of the flywheel;

[0173] During the press-fitting process, the support seat 406.4 of the shaft support mechanism 406 supports the lower part of the main shaft, and as the pressing action proceeds, the support seat 406.4 also drops synchronously to allow the shaft to be inserted into the flywheel, thereby realizing the rapid assembly of the shaft and the flywheel. After the assembly is completed, the assembled main shaft and flywheel are transferred to the flip device using a truss robot; then the mechanisms are reset to complete the assembly of the next pair of main shafts and flywheels, thereby realizing the automated press-fitting of the main shaft on the flywheel, saving time and effort.

[0174] The entire assembly process of the present invention does not require manual assistance, saves time and effort, is highly safe, improves the efficiency of the shaft and flywheel assembly, and lays a foundation for the automated assembly of the flywheel body. In addition, the third bearing seat 405.3 of the present invention is suitable for different discs, and the shaft clamping mechanism 403 is suitable for spindles of different diameters, thereby realizing the assembly of flywheels and spindles of different specifications.

[0175] Of course, the assembly object of the present invention is not limited to the assembly of a flywheel and a main shaft, and may also be the assembly of a disc member and a shaft member with the same installation method.
