Description

Technical Field

[0001] The invention relates to the field of assembly of a flywheel energy storage system, and in particular to a method for winding a wire group of an armature disk of a motor. Background Art

[0002] The flywheel energy storage system uses physical methods to store energy, and realizes the mutual conversion and storage between electrical energy and the mechanical kinetic energy of the high-speed running flywheel through the electric / generating reciprocal bidirectional motor. At present, the flywheel energy storage system has the advantages of high energy density, high conversion rate of electrical 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 bidirectional motor is the core component of the flywheel energy storage system. The armature disc of the bidirectional motor mainly includes two types: the discharge disc and the drive disc, which realize the mutual conversion between electrical energy and the mechanical kinetic energy of the high-speed running flywheel. Among them, the winding wire group on the discharge disc mostly adopts the spiral winding method, that is, a membrane-wrapped wire is spirally wound on the disc body of the armature disc in the order from the outside to the inside.

[0004] At present, the winding of the film-wrapped wire winding of the discharge armature disk is almost entirely done manually. The film-wrapped wire is manually wound in the wire slot of the armature disk in a spiral winding manner from the outside to the inside. Two people work in a group during the winding process. During the winding process, 502 glue needs to be continuously used to fix the film-wrapped wire. After winding, AB glue needs to be applied to the armature disk. Each finished armature disk takes at least 60 minutes, and the winding efficiency is low, which increases the labor cost of the flywheel body in disguise. In addition, the film-wrapped wire is prone to damage during the winding process, affecting the performance of the motor. Summary of the invention

[0005] In view of this, the invention provides a method for winding a wire group of an armature disk of a motor, which realizes automatic winding and winding wire groups, as well as rapid bonding of the winding wire groups and the armature disk, improves the winding efficiency of the armature disk, and overcomes the problem of low winding efficiency of existing assembly lines.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The method for winding a wire group of an armature disk of a motor according to the present invention comprises the following contents:

[0008] Step S1, installing the wire drum of the film-wrapped wire on the rotating shaft of the winding mechanism, passing the wire end of the film-wrapped wire through the wire pressing wheel of the winding mechanism, and then pulling it to the winding assembly of the winding mechanism through the wire feeding and tensioning mechanism, so that the film-wrapped wire passes through the bottom of the winding assembly;

[0009] Step S2, the control system sends an action command to the second power mechanism of the winding mechanism, so that the winding assembly is located above the right part of the winding drum of the winding forming and separation mechanism, and the height of the winding assembly is adjusted so that the film-wrapped wire is pressed into the forming groove of the winding drum;

[0011] The control system controls the first power mechanism of the forming and separating mechanism to drive the winding disk to rotate circumferentially to ensure that the area to be wound is always located in the winding activity area of ​​the winding assembly; the first power mechanism and the second power mechanism are linked to wind the membrane wire on the winding disk in a spiral winding manner of first outside and then inside;

[0012] While winding, the adhesive is applied to the wire slots of the armature disc, and the adhesive on the armature disc is treated to make it sticky;

[0013] Step S4, after the film-wrapped wire is wound, the control system controls the second power mechanism to make the winding assembly rise and move away from above the winding drum; the armature disk (the adhesive is treated with blue light to generate viscosity) in step S3 is covered on the winding drum;

[0014] Step S5, the control system sends a press-fitting instruction to the armature disc press-fitting mechanism, the armature disc press-fitting mechanism moves to the top of the armature disc, and the third power mechanism of the armature disc press-fitting mechanism drives the pressing member to press the armature disc downward, so that the wire group on the winding disc and the armature disc are adhered together;

[0015] Step S6, after the preset pressing time, the armature disc pressing mechanism is reset; the control system sends a lifting command to the fourth power mechanism of the winding forming and separation mechanism, and the fourth power mechanism drives the separation disc to drive the separation member to rise into the forming groove, and push the wire group off the winding disc.

[0017] Adhesive can be applied to the armature disk while winding the wire, and the armature disk is pressed onto the winding disk by a pressing mechanism, so that the wound wire group is adhered to the armature disk, and finally the winding shaping and separation mechanism is used to push the wire group off the winding disk, thereby realizing automatic gluing of the winding wire group and the armature disk, greatly improving the winding efficiency of the wire group on the armature disk, saving time, effort and manpower.

[0020] When winding the wire, the control system provides the film-wrapped wire with the wire-releasing power source.

[0021] In the above scheme: the wire-paying power source can control the rotation speed of the rotating shaft and the wire drum, and then control the wire-paying force; the lead-in structure provides traction power for the membrane-wrapped wire to ensure normal wire supply.

In this additional solution, the two limiting members can fix the wire drum on the rotating shaft, ensure the fixing effect of the wire drum, and avoid affecting the release of the wire due to the axial movement of the wire drum along the rotating shaft.

[0023] In a preferred embodiment of the present invention, the wire feeding tensioning mechanism in step S1 includes a second vertical frame and a wire lead seat horizontally arranged on the upper part of the second frame, and a tensioning wheel that is lifted and lowered along the second frame is arranged on the second frame below the wire lead seat, and the film-wrapped wire passes through the wire lead seat through the wire lead structure and is wound around the tensioning wheel. Specifically, the wire lead seat has two threading holes arranged at intervals, and the tensioning wheel and the two threading holes are distributed in a triangular shape, thereby ensuring the tensioning effect of the film-wrapped wire.

[0024] More preferably, the multiple guide components and the multiple anti-slip components between the winding disk and the separation disk can not only ensure the lifting and lowering of the separation disk, but also ensure that the separation disk rotates synchronously with the winding disk;

[0025] Each of the guide assemblies comprises a first guide member fixed on the winding disc and a sliding member fixed on the separation disc, wherein the sliding member is slidably mounted on the first guide member; during actual installation, the guide assembly can be installed in two or three circles to ensure force balance and lifting accuracy of the separation disc;

[0026] The edge of the separation disk is provided with a plurality of limit grooves at intervals, and each of the anti-slip components comprises a second guide fixed to the lower surface of the winding disk and an anti-slip member fixed to the lower part of the second guide, and the second guide is slidably matched with the limit groove; the anti-slip member enables the winding disk to always be located below the winding disk. In addition, the separation disk can also be lifted and lowered along the second guide, further improving the lifting stability of the separation disk.

[0027] Preferably, the fourth power mechanism includes at least two linear power sources for driving the separation disc to rise and fall. More preferably, the fourth power mechanism includes a plurality of first cylinders (of course, they can also be hydraulic cylinders) arranged at intervals along the circumference, the cylinder body of each cylinder is fixed on the separation disc, and the end of the piston rod is fixed on the winding disc, and the separation disc and the cylinder body are lifted and lowered by the relative fixation and reaction force of the piston rod, thereby achieving the rise and reset of the separation member to ensure that the formed wire group is successfully separated from the winding disc.

[0028] Preferably, the armature disc press-fitting mechanism further comprises a press-fitting frame and a fifth power mechanism for driving the press-fitting frame to move back and forth transversely, and a transverse first guide pair is provided between the press-fitting frame and the operating table;

[0029] The clamping member is a clamping plate horizontally arranged in the press frame, the third power mechanism is a linear power source for driving the clamping plate to rise and fall, and a vertical second guide pair is arranged between the clamping plate and the press frame.

[0030] In the above scheme, the fifth power mechanism can be a rod cylinder or a rodless cylinder, or a hydraulic cylinder or a motor-driven screw, etc., which can be flexibly selected according to space requirements and work requirements.

[0031] The third power mechanism can be a cylinder, or a hydraulic cylinder or a motor-driven screw, etc. Its purpose is to drive the clamping plate to rise and fall to achieve the press-fitting of the armature disc. After pressing for a certain period of time, the third power mechanism electric clamping plate resets, and the fifth power mechanism drives the entire mechanism to move to the right to the initial position to facilitate the press-fitting of the next armature disc.

[0032] Preferably, the winding mechanism comprises a third frame body disposed transversely on the operating table, a first sliding seat slidably disposed on the third frame body, and a second sliding seat slidably disposed on the first sliding seat;

[0033] The second power mechanism includes a first power source for driving the first sliding seat to move back and forth horizontally along the third frame, a second power source for driving the second sliding seat to move up and down along the first sliding seat, and a third power source arranged on the second sliding seat, and the third power source drives the winding assembly to rotate.

[0034] In the above scheme: the height of the winding assembly can be adjusted to ensure that the winding assembly presses the membrane-wrapped wire into the forming groove, and the winding assembly is raised and reset after the winding is completed; the winding assembly can also move and rotate horizontally, and the two cooperate with each other to slowly rotate and move horizontally, so that the winding assembly is wound along the S-shaped trajectory on the winding disk, realizing automated winding and laying the foundation for improving the automatic winding of the wire group on the armature disk.

[0035] Preferably, the winding assembly includes a connecting seat connected to the third power source and a vertically arranged connecting plate. A threading block is arranged on the oblique side of the connecting plate, and a wire pressing seat is arranged on the bottom side of the connecting plate. After the membrane wrapped wire passes through the threading block, it enters the wire pressing seat and passes out from the bottom of the wire pressing seat to ensure the trajectory of the membrane wrapped wire.

[0036] More preferably, the wire pressing seat is an L-shaped structure, the vertical section of which has an oblique hole corresponding to the threading block and the horizontal section of which has a lead-in hole for the membrane-wrapped wire to pass through, the oblique hole and the lead-in hole are connected, and a pressing ring is also provided on the wire pressing seat corresponding to the lead-in hole. With this additional solution, the membrane-wrapped wire passes through the threading block and is led out through the oblique hole, the perforation and the pressing ring. During the linkage process of the first power source and the third power source, the pressing ring presses the membrane-wrapped wire into the forming groove, realizing S-shaped winding.

[0037] Compared with the prior art, the invention has the following advantages:

[0038] The permanent magnet motor of the flywheel energy storage system has a driving armature disk that drives the flywheel to rotate at high speed and a discharge armature disk that dilutes the electric energy. The wire group on the discharge armature disk is a spiral structure, and each circle is an S-shaped structure formed by alternating outward convex arc-shaped bending sections and inward concave arc-shaped bending sections. The structure of the wire group is relatively complex. Therefore, how to wind the wire group on the disk body of the armature disk is a difficult problem that plagues the development of the flywheel industry.

[0039] To this end, the invention utilizes a wire unwinding mechanism and a wire feeding and tensioning mechanism to pull the film-wrapped wire onto the winding assembly of the winding mechanism; the winding disk of the winding shaping and separation mechanism can be rotated intermittently, thereby rotating the blank area below the winding assembly; the second power mechanism connected to the winding assembly can not only rotate but also move horizontally, thereby ensuring that the winding assembly is continuously wound along a spiral winding method from the outside to the inside, and during the winding process, the winding assembly is adjusted to be wound in an S-shaped manner through the second power mechanism, thereby realizing automatic winding of the winding wire group on the discharge armature disk, with high winding efficiency, thereby improving the production efficiency of the finished armature disk;

[0040] While winding, adhesive is applied to the armature disk manually or by a robot and the adhesive is illuminated with blue light to make the adhesive sticky; the armature disk with adhesive is covered on the winding disk, and the pressure of the armature disk pressing mechanism can make the upper surface of the formed wire group adhere to the wire groove of the armature disk. Finally, the winding shaping and separation mechanism is used to push the wire group out of the winding disk to complete the armature disk wire group winding operation. The degree of automation is high, and its processing efficiency is more than three times that of traditional manual winding, laying a foundation for realizing the automatic assembly of the flywheel body in the flywheel energy storage system.

[0056] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. This embodiment is implemented based on 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 embodiments. It should be noted that the armature discs mentioned in the following embodiments are all discharge armature discs of the disc permanent magnet machine of the flywheel energy storage system, and their structure is as follows: Fig.15 shown.

[0057] Embodiment 1 The present invention provides a motor armature coil winding device

[0058] like Figure 1 As shown, the automatic winding device for the motor armature disk described in this embodiment includes

[0059] The wire unwinding mechanism 10 comprises a fixing assembly 101 for fixing the wire drum and a lead-in structure 102 for leading out the film-wrapped wire on the wire drum, and the height of the lead-in structure 102 is higher than the height of the fixing assembly 101;

[0060] The fixed frame 20 has a horizontally arranged operating table 201. The fixed frame 20 is also covered with a cabinet plate, and the first power mechanism described later can be installed in the cavity surrounded by the cabinet plate to protect the first power mechanism;

[0061] The wire feeding tensioning mechanism 30 is arranged at the edge of the operating table 201 and has a tensioning wheel 301 for tensioning the membrane wrapped wire to ensure normal wire feeding;

[0062] The winding shaping and separation mechanism comprises a shaping mechanism 40 and a separation mechanism 70, wherein the shaping mechanism 40 comprises a winding disk 401 driven to rotate by a first power mechanism 403, and the winding disk 401 has a plurality of molding grooves 402 which are consistent with the trajectory of the film wrapped wire on the armature disk (the plurality of molding grooves are spiral structures, and each circle is an S-shaped structure with alternating concave and convex, and continuous winding can be achieved by using one film wrapped wire during winding); the separation mechanism 70 comprises a separation disk 701 driven to rise and fall by a fourth power mechanism, and the separation disk 701 has separation members (i.e., vertically arranged top columns 702), the layout trajectory of the top columns 702 is consistent with the trajectory of the molding groove 402 and corresponds to each other up and down, and the top columns 702 can lift the film wrapped wire in the molding groove 402 onto the armature disk when they rise;

[0063] The winding mechanism 50 is horizontally mounted on the operating table 201. The winding mechanism 50 has a winding assembly 501 driven to rotate by the second power mechanism. The winding assembly 501 is located above the winding disk 401 and presses the membrane-wrapped wire into the molding groove 402 in a spiral winding order from outside to inside; and

[0064] The armature disc pressing mechanism 60 comprises a pressing frame 601 and a pressing member driven by a third power mechanism, and the pressing member presses the armature disc onto the winding disc 401 .

[0065] During actual installation, the top posts 702 are densely arranged to ensure that the membrane-wrapped wire is evenly stressed and that the wound wire group is pushed upward out of the winding drum 401, thereby reducing damage caused by uneven stress on the membrane-wrapped wire.

[0066] When working, the invention uses the pay-off mechanism 10 and the wire feeding and tensioning mechanism 30 to pull the film-wrapped wire to the winding assembly 501 of the winding mechanism 50; the blank area of ​​the winding disk 401 can be rotated to the bottom of the winding assembly 501, ensuring that there is always a blank area to be wound below the winding assembly 501, so as to achieve continuous winding;

[0067] The second power mechanism can not only rotate but also move horizontally, ensuring that the winding assembly 501 is wound in an S-shape along the forming groove 402 on the winding disk 401 (consistent with the wire groove trajectory on the discharge armature disk), thereby realizing automatic winding of the winding wire group; the winding shaping and separation mechanism and the second power mechanism work together to ensure continuous winding; in addition, while winding, adhesive can be applied to the armature disk, and the armature disk can be pressed onto the winding disk 401 by using the pressing mechanism, so that the wound wire group is adhered to the armature disk, and the winding shaping and separation mechanism 70 is used to push the wire group away from the winding disk 401, thereby realizing automatic bonding of the winding wire group and the armature disk, thereby improving the winding efficiency of the wire group on the armature disk, saving time, effort and manpower.

[0068] like Figure 3-4 As shown, the fixed assembly 101 also includes a first frame, the first frame has a leg 101.3 and a mounting seat 101.4 horizontally arranged on the leg 101.3; the fixed assembly 101 includes a left support 101.1 and a right support 101.2 arranged on the mounting seat 101.4, and a rotating shaft 103.1 is passed through the left support 101.1 and the right support 101.2, one end of the rotating shaft 103.1 is connected to the wire-releasing power source 103.2 on the right support 101.2, and the other end of the rotating shaft 103.1 is detachably connected to the left support 101.1, so as to facilitate the replacement of the wire drum, and the rotating shaft can rotate relative to the left support to ensure normal wire-releasing operation. During operation, the wire drum can be passed through the rotating shaft 103.1, and the wire-releasing power source 103.2 is used to control the wire-releasing force of the wire drum, thereby controlling the wire-releasing speed.

[0069] During actual installation, since the film-wrapped wire on the winding reel 401 is pressed at a slow speed, the wire-releasing speed is also relatively slow. To better control the wire-releasing speed, the wire-releasing power source 103.2 preferably has a motor reducer with a reduction ratio. Of course, the first power mechanism 403 may also be a gear transmission mechanism with a reduction ratio.

[0070] In order to avoid the problem of inconvenience in replacement caused by tight fit between the rotating shaft 103.1 and the inner diameter of the wire drum, and the problem of relative rotation between the wire drum and the rotating shaft 103.1 caused by clearance fit, the fixing assembly 101 also includes a limiting unit. Specifically:

[0071] like Figure 3 As shown, the limiting unit includes a pair of limiting members (i.e., limiting seats 104 in a T-shaped structure) arranged at intervals, wherein one limiting seat 104 (i.e., located on the left side of the wire drum) is fixed to the rotating shaft 103.1 by bolts, and correspondingly, the rotating shaft 103.1 has a fixing plane corresponding to the bolts to ensure the fixing effect of the upper cover limiting seat 104; the fixing plane has a certain length and can be suitable for the fixing and installation requirements of wire drums of different specifications; the other limiting seat 104 (located on the right side of the wire drum) has an internal threaded hole, and one end of the rotating shaft 103.1 has a section of external thread, and the limiting seat 104 is threadedly connected to the rotating shaft 103.1.

[0072] When installing the wire drum, remove the left end of the rotating shaft from the left support, then pass the wire drum through the rotating shaft 103.1, and install the rotating shaft on the left support; then use bolts to fix the left limit seat 104 on the rotating shaft 103.1 to achieve the left limit of the wire drum, start the motor reducer to make the right limit seat 104 move to the left along the rotating shaft 103.1 to achieve the right limit of the wire drum, thereby achieving the fixation of the wire drum.

[0073] In one embodiment of the invention: Figure 3-4 As shown, the lead structure 102 includes a vertically arranged fixing member 102.1 (a longitudinal beam made of a profile), and a pair of crimping wheels 102.2 spaced apart from each other are arranged on a fixing seat 102.8 above the fixing member 102.1, one of the crimping wheels 102.2 (i.e. Figure 1 The crimping wheel located above is connected to the first motor 102.3 on the fixed seat 102.8 by transmission, and the traction force provided by the first motor 102.3 is used to make the film-wrapped wire pass between the two crimping wheels 102.2.

[0074] like Figure 4 As shown, the upper crimping wheel 102.2 is fixedly connected to an adjustment seat 102.5 through an anti-drop cap 102.4, and the mounting seat 101.4 is provided with a first slider 102.7 which cooperates with the first slide rail 102.6 on the adjustment seat 102.5, so that the active crimping wheel 102.2 can be fine-tuned up and down to meet the traction requirements of the membrane wrapping line.

[0075] In one embodiment of the invention: Figure 5-6 As shown, the wire feeding tensioning mechanism 30 includes a second vertical frame 303 and a lead-in seat 302 horizontally arranged on the upper part of the second frame 303. The lead-in seat 302 has a pair of threading holes 302.1 arranged at intervals. The tensioning wheel 301 is arranged below the lead-in seat 302. After the film-wrapped wire passes through the two threading holes 302.1, it bypasses the tensioning wheel 301 and enters the clamping assembly described later. The film-wrapped wire is tensioned by the tensioning wheel 301. The specific trajectory is shown in FIG. Figure 1 shown.

[0076] like Figure 5-6 As shown, in order to ensure the tensioning effect of the membrane wire, the tensioning wheel 301 is slidably arranged on the second frame 303 through the sliding seat F, and when subjected to force, it rises and falls along the second frame 303 to achieve real-time tensioning of the membrane wire.

[0077] In one embodiment of the invention: Figure 1 and 4 -5, the second frame 303 includes a vertical rod 303.1 arranged at the upper edge of the operating table 201 and an auxiliary rod 303.2 arranged on the vertical rod 303.1 through a connecting piece, and a sliding seat F is passed through the upper part of the auxiliary rod 303.2 and the vertical rod 303.1. The sliding seat F carries the tensioning wheel 301 to rise and fall along the vertical rod 303.1 and the auxiliary rod 303.2, so that the membrane wrapping line is in a tensioned state.

[0078] In addition, during actual processing, the second frame 303 may also be made of vertical beams made of profiles.

[0079] In one embodiment of the invention: the second power mechanism of the winding mechanism 50 can realize the horizontal reciprocating, lifting and rotating of the winding assembly 501 to ensure normal winding operation. Specifically:

The third slider on the second sliding seat 502.2 is slidably mounted on the third slide rail 502.5 to ensure the lifting accuracy of the second sliding seat 502.2. Due to the installation space, the second power source is preferably connected to the third motor 502.6 and the third lead screw (of course, it can also be replaced by a cylinder) to ensure the movement accuracy of the winding assembly 501.

[0084] The second sliding seat 502.2 includes a vertical sliding member and a horizontally arranged mounting frame 502.7. The third power source is preferably a fourth motor 502.8 arranged on the mounting frame 502.7. The fourth motor 502.8 is connected to a vertical transmission shaft 502.9. The winding assembly 501 is arranged at the lower part of the transmission shaft 502.9. When the fourth motor 502.8 is working, its transmission shaft 502.9 drives the winding assembly 501 to rotate.

[0085] During operation, the first power source is used to move the winding assembly 501 to above the wire pressing area of ​​the winding drum 401, and then the second power source is used to drive the winding assembly 501 to descend to a certain height to ensure that the winding assembly 501 can press the membrane wrapped wire into the molding groove 402; then the first power source and the second power source are linked to make the winding assembly 501 press the membrane wrapped wire into the molding groove 402 along the trajectory of the molding groove 402, thereby realizing automatic winding of the winding drum 401.

[0086] During actual installation, there are multiple installation methods between the transmission shaft 502.9 and the mounting frame 502.7. The transmission shaft 502.9 can be fixed on the mounting frame 502.7 through a bearing seat, so that the transmission shaft 502.9 can be rotated and relatively fixed, thereby ensuring the force balance of the winding assembly 501; a section of thread can also be processed on the upper part of the transmission shaft 502.9, and the nut on the threaded section of the transmission shaft 502.9 is fixed on the mounting frame 502.7, thereby providing support for the transmission shaft 502.9 to ensure the force balance of the winding assembly 501.

[0087] In one embodiment of the invention: Fig.14As shown, the winding assembly 501 includes a connecting seat 501.1 connected to the third power source (the connecting seat 501.1 fixes the lower part of the transmission shaft 502.9 of the third power source) and a vertically arranged connecting plate 501.2, the lower part of the connecting plate 501.2 has a bevel, and a threading block 501.3 with a through hole is arranged at the bevel position, and one side of the threading block 501.3 is parallel to the bevel, so that the membrane package wire passes through the threading block 501.3 obliquely, which has a guiding effect;

[0088] A wire pressing seat 501.4 is provided at the lower part of the connecting plate 501.2. The wire pressing seat 501.4 has an inclined hole 501.5 coaxial with the through hole of the threading block 501.3 and a vertical lead-out hole. The lead-out hole and the inclined hole 501.5 are connected, so that the membrane-wrapped wire passes through the threading block 501.3 and the inclined hole successively and then comes out from the lead-out hole. A wire pressing ring 501.6 is provided at the bottom of the wire pressing seat 501.4 corresponding to the lead-out hole. The wire pressing ring 501.6 can press the membrane-wrapped wire coming out of the lead-out hole into the molding groove 402, thereby realizing automatic winding.

[0089] like Figure 13-14 As shown, the wire pressing seat 501.4 is preferably an L-shaped structure, the oblique hole is opened on its vertical section and the outlet of the lead-out hole is located in the horizontal section, and the oblique hole and the lead-out hole are connected, and the angle between the axis of the oblique hole and the axis of the lead-out hole is an obtuse angle, which lays a foundation for realizing normal winding of the membrane-wrapped wire. Of course, the wire pressing seat 501.4 can also be a rectangular block, a trapezoidal block or other structures, and the wire pressing seat 501.4 of the invention is not limited to an L-shaped structure.

[0090] In one embodiment of the invention: Figure 1 and Figure 7 As shown, the first power mechanism 403 of the winding shaping and separation mechanism is installed inside the fixed frame 20, which includes a fifth motor 403.2 and a gear transmission pair with a reduction ratio that is transmission-connected to the fifth motor 403.2; the first power mechanism 403 also includes a rotating seat 403.1 with a cylindrical structure that is transmission-connected to the gear transmission pair; a mounting hole that cooperates with the rotating seat 403.1 is opened on the winding drum 401, and the winding drum 401 is fixed on the rotating seat 403.1, thereby realizing the transmission connection between the fifth motor 403.2 and the winding drum 401. When working, the fifth motor 403.2 can drive the winding disk 401 to rotate through the gear transmission pair and the rotating seat 403.1, so that the forming groove 402 to be wound is rotated to the wire pressing area, so that the winding mechanism 50 can press the membrane wrapped wire into the forming groove 402; when the forming groove 402 in this area is pressed with the membrane wrapped wire, the winding disk 401 is rotated again to make the forming groove 402 to be wound rotate to the wire pressing area, and this is repeated to press the membrane wrapped wire into each forming groove 402 in turn.

[0091] In one embodiment of the invention, in order to facilitate winding, a starting groove 401.1 is provided on the upper surface of the winding drum 401, and the starting end of the forming groove and the winding end are both located in the starting groove 401.1. Figure 8 shown.

[0092] The armature disc press-fitting mechanism 60 can press-fit the armature disc with adhesive onto the winding disc 401 to ensure that the molded wire on the winding disc 401 can be adhered to the winding disc 401, thereby realizing automatic winding of the armature disc. Specifically:

[0093] like Figure 1 and Figure 11-12 As shown, a pressing member (i.e., a pressing plate 602) driven to rise and fall by a third power mechanism is provided in the pressing frame 601. The third power mechanism includes a pair of second cylinders 603 spaced apart on the top of the pressing frame 601. The piston rod of each second cylinder 603 is fixedly connected to the pressing plate 602, and the second cylinder 603 is used to realize the lifting and lowering of the pressing plate 602.

[0094] like Fig.12 As shown, a vertical second guide pair is arranged between the pressing plate 602 and the pressing frame 601, and the second guide pair has four pairs, and each pair of the second guide pairs includes a vertically arranged third guide shaft 604.1 and a vertically arranged third sliding sleeve 604.2 (preferably a linear bearing), the third sliding sleeve 604.2 is fixed on the top plate of the pressing frame 601 and the third guide shaft 604.1 is fixed on the pressing plate 602, and the third guide shaft 604.1 freely passes through the third sliding sleeve 604.2 to ensure the movement accuracy of the pressing plate 602;

[0095] During actual processing, the bottom plate of the press-fitting frame 601 has an open groove to ensure that the press-fitting frame 601 can smoothly pass through the rotating seat 403 . 1 so that the clamping disk 602 is pressed on the winding disk 401 to ensure the press-fitting effect.

[0096] In one embodiment of the invention: Fig.11 As shown, the armature disc pressing mechanism 60 also includes a fifth power mechanism for driving the pressing frame 601 to move back and forth horizontally, and the fifth mechanism includes a pair of third cylinders 605 (preferably rodless cylinders with a larger working stroke, but ordinary cylinders can also be used) arranged laterally, and the bottom plate of the pressing frame 601 is fixed on the cylinder body of the third cylinder 605, and the pressing frame 601 can move back and forth left and right through the cylinder body;

[0097] There is a transverse first guide pair between the press-fitting frame 601 and the operating table 201. The first guide pairs are divided into two pairs. Each pair of first guide pairs includes a fourth slide rail 606.1 transversely arranged on the operating table 201. A fourth slider 606.2 cooperating with the fourth slide rail 606.1 is arranged on the bottom plate of the press-fitting frame 601. The two first guide pairs are arranged front and back to provide and guide for the left and right reciprocating movement of the press-fitting frame 601, thereby ensuring the stability of the press-fitting frame 601.

[0098] During operation, after the winding (i.e. winding the membrane-wrapped wire on the winding reel 401 according to the winding trajectory of the armature disc) is completed, an armature disc with adhesive is placed horizontally above the winding reel 401, and the cylinder body of the third cylinder 605 drives the pressing frame 601 and the clamping plate 602 in the pressing frame 601 to move to the left, so that the clamping plate 602 is located directly above the armature disc; the piston rod of the second cylinder 603 extends downward, thereby pressing the clamping plate 602 on the armature disc and maintaining the preset time (such as continuous pressing for 3-10 seconds) to ensure that the armature disc and the membrane-wrapped wire are bonded together.

[0099] After the press-fitting is completed, the armature disc press-fitting mechanism 60 is reset, and the top column 702 of the winding shaping and separation mechanism 70 rises to push the membrane-wrapped wire upward, thereby realizing the separation of the membrane-wrapped wire.

[0100] like Figure 9-10 As shown, the winding shaping and separation mechanism 70 also includes a guide component and an anti-slip component; wherein:

[0101] The anti-slip assembly includes a second guide member (i.e., a second guide shaft 703.1, which is an optical axis) fixed at the outer peripheral edge of the winding drum 401 and an anti-slip platform 703.3 arranged at the lower part of the second guide shaft 703.1;

[0102] A plurality of limit grooves 703.2 are spaced apart at the outer edge of the separation disc 701. The limit portion of the limit groove 703.2 is an arc-shaped structure that cooperates with the second guide shaft 703.1. The second guide shaft 703.1 slides with the limit groove 703.2, so that the separation disc 701 can be lifted and lowered along the second guide shaft 703.1, thereby having a guiding effect. A plurality of anti-detachment platforms 703.3 are arranged along the circumferential direction of the separation disc 701, and the anti-detachment platforms 703.3 are all located below the separation disc 701, thereby ensuring that the separation disc 701 is always horizontally mounted below the separation disc 701.

[0103] like Fig. 9 As shown, the structures of the multiple guide assemblies are the same, and each guide assembly includes a first guide member (i.e., a first guide shaft 704.1, preferably an optical shaft) fixed on the winding disk 401 and a sliding member (i.e., a first sliding sleeve 704.2, preferably a linear bearing) fixed on the separation disk 701, and the first sliding sleeve 704.2 is sleeved on the first guide shaft 704.1 and slidably matched with the first guide shaft 704.1;

[0104] like Fig. 9 As shown, the guide assembly has two circles, one circle of the guide assembly is close to the inner edge of the separation disk 701, and the other circle of the guide assembly is close to the outer peripheral edge of the separation disk 701. The guiding effect of the two circles of the guide assembly ensures the lifting accuracy of the separation disk 701.

[0105] The invention utilizes the anti-slip assembly not only to limit the separation disc 701, but also has a guiding function. The anti-slip assembly and the guiding assembly enable the separation disc 701 to be lifted and lowered along the first guide shaft 704.1 and the second guide shaft 703.1, ensuring that the separation disc 701 is subjected to balanced force, thereby achieving stable lifting and lowering and improving movement accuracy.

[0106] In other embodiments of the invention: Fig.10 As shown, the length of the second guide shaft 703.1 is about 2-4 times the thickness of the separation disc 701, providing lifting space for the separation disc 701.

[0107] In one embodiment of the invention: Figure 9-10 As shown, the fourth power mechanism includes a plurality of linear power sources (i.e., first cylinders 705) spaced apart along the circumferential direction of the separation disc 701, and each first cylinder 705 is close to a second guide shaft 703.1. The cylinder body of the first cylinder 705 is fixed on the upper surface of the separation disc 701, and the piston rod of the first cylinder 705 passes through the separation disc 701 and is fixed on the winding disc 401. The winding disc 401 is fixed on the rotating seat 403.1, and the winding disc 401 is fixedly installed relative to the separation disc 701.

[0108] During operation, when the piston rod of the first cylinder 705 is extended, the piston rod applies a reaction force to the cylinder body, thereby causing the separation disc 701 to steadily descend through the guide assembly and the anti-slip assembly; when the piston rod of the first cylinder 705 is retracted, the reaction force of the piston rod of the first cylinder 705 causes the separation disc 701 to steadily rise along the first guide member and the second guide member, and the ejector column 702 on the separation disc 701 ejects the molded membrane wire in the molding groove 402, thereby realizing the automatic assembly of the wound membrane wire and the armature disc.

[0109] Implementation Method 2

[0112] Step S2, the control system sends an action command to the second power mechanism of the winding mechanism, so that the winding assembly moves to the upper part of the right part of the winding drum, and adjusts the height of the winding assembly to ensure that the wire pressing ring can press the film-wrapped wire into the forming groove 402 of the winding drum 401;

[0113] Step S3, the control system sends a horizontal reciprocating and forward and reverse linkage winding instruction to the second power mechanism, so that the winding assembly winds the film-wrapped wire in the forming groove 402 in an S-shaped route;

[0114] The control system controls the first power mechanism to drive the winding disk to rotate circumferentially to ensure that the area to be wound is always located within the winding activity area of ​​the winding assembly; the first power mechanism and the second power mechanism are linked to enable the winding assembly to wind the membrane wire on the winding disk in a spiral winding manner of first outside and then inside;

[0115] During winding, apply adhesive (self-adhesive) to the wire slot of the armature disc, and apply blue light to the self-adhesive to make it sticky; a robot can be used for gluing.

[0116] Step S4, after the film-wrapped wire is wound, the control system controls the second power mechanism to make the winding assembly rise and move away from the winding disk, and the winding assembly is reset to wait for the next winding instruction; the armature disk coated with glue in step S3 is covered on the winding disk to lay a foundation for the bonding of the formed winding;

[0117] Step S5, the control system sends a press-fitting instruction to the third cylinder 605, the press-fitting frame 601 moves to the top of the armature disc, and the second cylinder 603 of the armature disc press-fitting mechanism drives the pressing disc 602 to press the armature disc downward, so that the formed wire group on the winding disc 401 and the armature disc are adhered together;

[0118] Step S6, after the preset pressing time (generally about 3-10 seconds), the armature disc pressing mechanism is reset; the control system sends a lifting command to the first cylinder 705, the piston rod of the first cylinder 705 retracts to drive the separation disc 701 to drive the push column 702 to rise into the forming groove 402, and the formed wire group is pushed away from the winding disc 401 to facilitate the winding of the next wire group, thereby realizing the assembly line winding of the armature disc.

[0119] In the above technical scheme: the present invention utilizes a wire unwinding mechanism and a wire feeding and tensioning mechanism to pull the film-wrapped wire onto the winding assembly of the winding mechanism; the winding disk can rotate to ensure that the area to be wound on the winding disk is always located within the winding activity area of ​​the winding assembly, and the second power mechanism continuously winds the wire along the track of the formed groove on the winding disk through the winding assembly, thereby realizing the automatic winding of the winding wire group on the armature disk;

[0120] Adhesive can be applied to the armature disk while winding the wire, and the armature disk is pressed onto the winding disk by a pressing mechanism, so that the wound wire group is adhered to the armature disk, and finally the winding shaping and separation mechanism is used to push the wire group off the winding disk, thereby realizing automatic gluing of the winding wire group and the armature disk, greatly improving the winding efficiency of the wire group on the armature disk, saving time, effort and manpower.
