Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to an automatic winding device for processing motor coils. Background Technology

[0002] An electric motor, commonly known as a "motor," is a core electromagnetic device that converts electrical energy into mechanical energy based on the law of electromagnetic induction. It is divided into two main categories: electric motors (symbol M) and generators (symbol G). It is widely used in various scenarios of production and daily life, and the winding of the enameled wire of the motor rotor is the core process of motor manufacturing.

[0003] However, in practical applications, there are still some unresolved problems. The following are some common problems of winding devices for motor coil processing: First, most of them are single-station fixed tooling, and the feeding, winding and unloading are done in steps and intermittently, resulting in poor automation continuity. Second, the wires before and after winding need to be cut manually and re-threaded, which frequently interrupts the production line and results in low processing efficiency. Summary of the Invention

The circular four-station synchronous flow layout allows for simultaneous parallel feeding, winding, and unloading. The cut-off part is only cut at the unloading station, and the wires at the processing station remain connected, eliminating the need for manual wire cutting and re-threading, thus eliminating process interruptions and waiting. The rotor intermittent turning mechanism can automatically switch the winding working surface without the need for manual disassembly and rotation of the rotor. The entire process is a continuous cycle operation, which effectively improves the batch processing capacity of rotor coils and reduces manual operation costs.

[0018] 2. Multiple positioning and anti-rotation structure to stabilize and improve the accuracy of coil processing and forming. First, the rotor is equipped with elastic V-shaped clamping blocks for adaptive clamping, preventing deviation during transport. After winding, the station switching is rigidly locked to avoid the rotor shifting due to wire pulling. Second, the pressing mechanism is combined with ratchet unidirectional transmission, and the base is completely locked during the winding process to prevent uneven wire laying caused by slight rotation of the station. Third, the tooling flipping, cutting, and positioning actions are all mechanically triggered in sequence, and the actions are synchronous and stable, which is suitable for long-term continuous processing conditions in the workshop.

Detailed Implementation

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1, referring to Figures 1-6 This is the first embodiment of the present invention. This embodiment provides an automatic winding device for processing electric motor coils, which includes a coil winding machine 1.

[0041] Specifically, the coil winding machine 1 is used for winding the rotor of an electric motor. It includes: a frame 11, which is fixedly installed; and a winding mechanism 12, which is installed on the frame 11 and is used for winding the rotor of the electric motor. The winding mechanism 12 adopts an existing CNC rotor winding head in the industry, which integrates copper wire feeding, tension control, and wire winding functions. It is specifically designed for the circular winding of enameled wire for the iron core of the motor rotor. It is only a supporting component for the whole machine and is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0042] The rotor rotary feeding mechanism 13 is mounted on the frame 11 and is used to intermittently and continuously feed material to the motor rotor. It works in conjunction with the winding mechanism 12 to complete the winding operation. The rotor rotary feeding mechanism 13 is the core conveying mechanism of this device. It adopts a multi-group linear array rotary station structure to realize the intermittent stepping cycle of rotor feeding, processing and unloading. It consists of a complete linkage link composed of a rotary drive component 131, a base 132, a circumferential array station component 133, an elastic positioning component 134, a cutting component 135, and a trigger component 136.

[0043] The rotor intermittent turning mechanism 14 is installed on the frame 11 and is used to intermittently turn and limit the rotation of a single rotor, so as to realize multi-faceted and all-round winding of the rotor and avoid rotor rotation during winding. The rotor intermittent turning mechanism 14 is an independent positioning auxiliary mechanism. After the winding process is in place, it selectively turns the rotor core intermittently to rotate at a fixed point, so as to realize multi-slot and multi-faceted all-round winding on the outside of the rotor. During the winding operation, the rotor can be locked to prevent the rotor from passively rotating and causing wire arrangement disorder and coil turn deviation.

[0044] The downward pressure anti-rotation mechanism 15 is installed on the frame 11 and is used to position the rotor after it has been intermittently fed by the rotor rotation feeding mechanism 13. This prevents the station on the rotor rotation feeding mechanism 13 from rotating during the winding process. The downward pressure anti-rotation mechanism 15 is a station locking reference mechanism. After the winding station is in place, it presses down the seat 132 and the station reference surface to lock the entire intermittent feeding flow station and prevent the rotation drive component 131 from moving in the processing gap and the station from micro-rotation.

[0045] Specifically, the rotor rotation feeding mechanism 13 includes: a rotation drive component 131, mounted on the frame 11; and several bases 132, which are linearly arrayed and fixed on the rotation drive component 131. The rotation drive component 131 is the intermittent power source for the entire workstation, outputting a sequential step intermittent rotation to control the intermittent circular flow of all bases 132. The workstation bearing base is arranged in a linear array of bases 132, and four sets of workstations are arranged in a ring around a single base 132 to achieve synchronous standby processing of four workstations on a single base.

[0046] There are several workstation components 133, which are arranged in a circular array on the four sides of multiple seats 132. They are used to place the motor rotor to be wound. They move intermittently along the circular path with the rotation drive component 131. The elastic positioning component 134 is installed on the seat 132 and is used for the elastic locking and positioning of the rotor. This makes it easy to put the rotor into the workstation and also restricts the rotor from shaking freely in the workstation. This ensures that the rotor is stable in position during feeding and winding.

[0047] The station component 133 is a dedicated placement fixture for the rotor core, distributed in a circumferential array, supporting the vertical motor rotor to be wound. The elastic positioning component 134 is an elastic clamping structure for the fixture, which clamps the motor rotor core with elastic force, ensuring smooth loading and unloading. Furthermore, when the rotor intermittent tossing mechanism 14 needs to toss the rotor core for intermittent fixed-point rotation, it can overcome the elastic limit and not affect the intermittent fixed-point rotation of the rotor core, thus realizing multi-slot, multi-faceted, all-round winding on the outside of the rotor.

[0048] Several cut-off pieces 135 are arranged in a circular array and fixed on the surface of multiple bases 132. They are used to automatically cut the coil leads when the winding is completed and the coil reaches the unloading position. The wires between the coil and the previous coil are not cut when the next rotor is wound. There is no need for manual cutting of the wires, which reduces the processing steps and improves the winding efficiency. At the same time, the cut-off pieces 135 can move synchronously with the bases 132 and can complete the cutting action when the coil is completed at each station and the coil reaches the unloading position. This adapts to the processing rhythm of intermittent feeding and ensures the continuity of processing.

[0049] The cutting component 135 moves synchronously with the workstation. Only the rotor unloading station automatically cuts the tail lead of the finished coil. The connecting enameled wire between the rotors before and after the processing station is not cut. This serves to fix the wire end of the conductor that needs to be wound on the rotor at the processing station, so that the rotor at the processing station can be wound smoothly. This enables the equipment to continuously and uninterruptedly thread and wind the wire. There is no need to manually cut the wire after each workpiece is completed, eliminating the process of re-threading the broken wire and greatly improving the efficiency of continuous production. Multiple sets of cutting components 135 are adapted to the rhythm of the intermittent stepping station. The cutting is triggered when the workstation moves to the correct position.

[0050] Trigger 136 is mounted on frame 11 and rotary drive 131, and cooperates with station 133, elastic positioning 134 and cutting 135 respectively. Trigger 136 does not rotate with station, and triggers station 133 posture switching, elastic positioning 134 clamping / releasing, cutting 135 tangential action and station reversal unloading according to processing sequence.

[0051] Example 2, refer to Figures 2 to 14 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0052] Specifically, the rotary drive component 131 includes: several bearing sleeves 1311, which are fixed to the frame 11 in a linear array. The bearing sleeves 1311 adopt high-precision wear-resistant sliding bearing seats, providing a vertical rotation reference for the rotating column 1312, bearing the axial load of the seat 132 and the rotor tooling, and having a dustproof sealing structure; several rotating columns 1312, which rotate in a linear array within multiple bearing sleeves 1311, and the rotating columns 1312 bear the load of all the work positions above; several ratchet wheels 1313, with the outer ring fixed to the upper end of the rotating column 1312. The ratchet wheels 1313 have a unidirectional transmission ratchet structure, with the outer ring being a ratchet meshing transmission surface and the inner ring being rigidly fixed to the short column 1314, so that the rotating column 1312 can only rotate intermittently in one direction. During winding machining, the pawl self-locks to prevent the spindle from reversing and springing back.

[0053] There are several short posts 1314, with the lower end of each short post 1314 fixed to the inner ring of the ratchet 1313. The seat 132 is fixed to the upper end of the short post 1314. The short posts 1314 are connected to the uprights and are coaxially fixed to the inner ring of the ratchet 1313 and the seat 132, ensuring that the seat 132 rotates coaxially with the rotating post 1312 and the ratchet 1313. The drive component 1315 is installed on the lower end of the rotating post 1312 and the frame 11. The drive component 1315 outputs periodic meshing power to drive the ratchet 1313 to rotate intermittently. This is prior art. The working principle of this part is also prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0054] The bottom drive component 1315 periodically drives the rotating column 1312 to act on the ratchet 1313, causing the short column 1314 to rotate intermittently in one direction, thereby driving the top seat 132 and the circumferential workstation to move synchronously in a ring. During the winding operation, the drive component 1315 pauses, the ratchet 1313 mechanically locks itself, the short column 1314 does not rotate, and the workstation is locked in conjunction with the downward anti-rotation mechanism 15.

[0055] Specifically, the workstation component 133 includes: a placement seat 1331, which is located on one side of the seat body 132, with one seat body 132 corresponding to four placement seats 1331. The four placement seats 1331 are arranged in a circular array on the four sides of the seat body 132. The placement seats 1331 serve as rotor core bearing fixtures. Each seat body 132 has four sets of ring-shaped arrangements, which do not interfere with each other and operate independently; a socket 1332, which is opened on the placement seat 1331 for inserting and placing the rotor. The socket 1332 matches the outer diameter of the motor rotor's central shaft, restricts the horizontal offset of the rotor, and establishes the winding reference center; and a short rod 1333, which rotates on the seat body 132 and has one end fixed to the surface of the placement seat 1331. The short rod 1333 is rotatably connected to the seat body 132 through a bearing. The short rod 1333 serves as the rotating support shaft of the workstation component 133. After unlocking, it can drive the overall angle of the placement seat 1331 to deflect, which is convenient for unloading.

[0056] A circular sleeve 1334 is fixed to the surface of the base 132 and sleeved on the other end surface of the short rod 1333; a torsion spring 1335 is sleeved on one end surface of the short rod 1333, and its two ends are fixed to the inner wall of the circular sleeve 1334 and the surface of the short rod 1333 respectively. The torsion spring 1335 is a reset elastic element. Under normal conditions, it maintains the standard horizontal machining posture of the placement base 1331. After being deflected by force, it deforms to provide a reset force.

[0057] Under normal conditions, the torsion spring 1335 keeps the four sets of placement seats 1331 horizontally ready. The rotor is inserted into the insertion hole 1332 to complete the basic positioning. The external triggering force drives the short rod 1333 to overcome the torque of the torsion spring 1335 and rotate, which drives the placement seat 1331 and the rotor after winding to reach the unloading position and then flips over to realize automatic workpiece unloading. Before this, the wire between the rotor and the next rotor has been cut off. After the force is removed, the torsion spring 1335 rebounds and the workstation part 133 quickly returns to the standard processing posture.

[0058] Specifically, the workstation component 133 also includes: a locking rod 1336, which slides through the circular sleeve 1334. The locking rod 1336 is a vertical sliding locking pin, which realizes the mechanical locking of the short rod 1333 and locks the workstation processing posture; a circular block 1337, which is fixedly sleeved on the upper end of the locking rod 1336; a spring 1338, which is sleeved on the surface of the locking rod 1336 and whose two ends are respectively fixed between the inner wall of the circular sleeve 1334 and the surface of the circular block 1337. The spring 1338 is an automatic reset component of the locking rod 1336. Under normal conditions, it pushes the locking rod 1336 upward to insert into the slot 13310, locking the short rod 1333 to prevent the workstation from deflecting; and a roller 1339, which rotates at the lower end of the locking rod 1336 and cooperates with the trigger component 136. The roller 1339 is a low-resistance driven trigger wheel that rolls with the trigger plate 1364 to convert the mechanical contact thrust into the vertical displacement of the locking rod 1336.

[0059] The slot 13310 is formed on the surface of the short rod 1333 and cooperates with the upper end of the locking rod 1336. The slot 13310 and the end of the locking rod 1336 cooperate to achieve angle positioning and locking. The bevel gear 13311 is fixedly sleeved on one end of the short rod 1333 and cooperates with the trigger 136. After the bevel gear 13311 reaches the position of the missing bevel gear ring 1366 with the placement seat 1331, it corresponds to the material unloading flipping position. As the bevel gear 13311 rotates, it meshes with the external missing bevel gear ring 1366. Before this, the trigger plate 1364 has acted on the roller 1339, so that the locking rod 1336 releases the locking of the short rod 1333. Thus, the bevel gear 13311 can rotate on its own axis while revolving around the revolution, so that the short rod 1333 and the placement seat 1331 can flip, drive the rotor to flip, and fall out of the unloading under the action of gravity.

[0060] The guide bar 13312 is fixed to the surface of the lever 1336 and slides on the sleeve 1334; the short rod 1333 has a movable plate 13313 fixed to its surface, and the inner wall of the sleeve 1334 has a stop block 13314 and a stop block 2 13315 respectively. The movable plate 13313 cooperates with the stop block 13314 and the stop block 2 13315 respectively. Through the movable plate 13313, the stop block 13314 and the stop block 2 13315, the rotation stroke of the short rod 1333 is limited, the maximum rotation angle of the placement seat 1331 is limited, and the overtravel mechanism is prevented from colliding and interfering.

[0061] Normal locking: Spring 1338 pushes the locking rod 1336 upward to engage with the slot 13310, and the short rod 1333 is locked at an angle, maintaining the fixed processing posture of the placement seat 1331 and the rotor; Trigger unlocking: After winding is completed, the workstation flows through the trigger plate 1364, and the roller 1339 is squeezed downward to push the locking rod 1336 out of the slot 13310, releasing the locking state of the short rod 1333; Angle adjustment unloading: The bevel gear 13311 meshes with the notched bevel gear ring 1366, driving the short rod 1333 and the rotor to rotate at a fixed point. Under the action of gravity, the completed rotor falls out for unloading; Reset locking: After leaving the trigger area, the short rod 1333 and the placement seat 1331 rotate back to reset under the action of the torsion spring 1335. At the same time, spring 1338 pushes the locking rod 1336 to reset and relock the slot 13310, ensuring the processing posture of the rotor placed subsequently.

[0062] Specifically, the top of the base 132 is provided with a groove 1321, and the elastic positioning member 134 realizes the adaptive elastic limit of the rotor. The elastic positioning member 134 includes: a number of locking blocks 1341, which slide in a circular array in the groove 1321. One end of the locking block 1341 is set at a V angle and cooperates with the rotor. The groove 1321 can accommodate multiple sets of locking blocks 1341 to slide radially. The V-angle end of the locking block 1341 cooperates with the rotor gap and is inserted into the rotor gap for elastic positioning. When the locking block 1341 is not abutted and limited by the limiting plate 1346, when the rotor intermittent tossing mechanism 14 needs to toss the rotor core to rotate intermittently at a fixed point, it can overcome the elastic limit and not affect the intermittent fixed point rotation of the rotor core, so as to realize multi-slot, multi-faceted all-round winding on the outside of the rotor.

[0063] A cube 1342 is fixed to the inner wall of the groove 1321; several springs 1343 are fixed at both ends between the surface of the locking block 1341 and the surface of the cube 1342, and the springs 1343 provide an elastic limiting force source; several positioning blocks 1344 are fixed to the top of the base 132 in a circular array; a guide post 1345 is fixed to the top of the locking block 1341; a guide hole is provided on the positioning block 1344, and the guide post 1345 slides in the guide hole. The positioning block 1344, the guide post 1345 and the guide hole are the guiding structure of the locking block 1341 to ensure that the locking block 1341 moves purely in translation and does not deviate or jam.

[0064] When the rotor of the lower discharge machine is in place, the rotor gap corresponds to the V-angle end of the clamping block 1341. After placement, the V-angle end of the clamping block 1341 is inserted into the rotor gap to position the rotor. When the material is intermittently rotated and fed to the winding position, the initial winding position of the workpiece is precisely aligned with the winding position on the winding mechanism 12 to avoid radial shaking of the rotor during the transfer and winding process.

[0065] Specifically, the elastic positioning component 134 further includes: a number of limiting plates 1346, which slide in a circular array on the base 132; a slide groove 1347, which is formed inside the base 132; a slider 1348, which is fixed to one side of the limiting plate 1346 and slides in the slide groove 1347, guiding and limiting the limiting plate 1346 through the slide groove 1347 and the slider 1348, so that it moves within a certain range; a spring 1349, which is fixed at both ends between the surface of the slider 1348 and the inner wall of the slide groove 1347; a roller 13410, which rotates at the lower end of the limiting plate 1346 and cooperates with the trigger component 136, and the upper end of the limiting plate 1346 cooperates with the locking block 1341.

[0066] The upper limit plate 1346 can lock the block 1341, preventing the block 1341 from moving towards the block 1342. It is no longer an elastic limit, but a rigid fixation on the rotor on the corresponding placement seat 1331. When rotating away from the winding station to the lower station, the wire is not cut off. When the rotor of the processing station is winding, the rotor after the previous winding will not rotate on the placement seat 1331, which serves to fix the wire end of the wire to be wound on the rotor of the processing station, so that the rotor of the processing station can be wound smoothly. The wire between the front and rear rotors can be cut off when rotating to the unloading station. This cycle is repeated, which serves to fix the wire end when the rotor after the previous winding is winding the next rotor. The spring three 1349 normally pushes the limit plate 1346 downward without limiting the block 1341. The roller two 13410 is a trigger driven wheel, which rolls with the trigger plate one 1362 to squeeze and push the limit plate 1346 to slide upward, limiting and constraining the block 1341.

[0067] Normal clamping: Spring 3 1349 pushes the limiting plate 1346 downward without limiting the locking block 1341, and the locking block 1341 elastically positions the rotor; Elastic limiting at the processing station: Same as normal clamping; Locking during the process from the processing station to the unloading station: When the station moves to this area, roller 2 13410 contacts trigger plate 1 1362, squeezing and pushing the limiting plate 1346 to slide and lock the locking block 1341, limiting and constraining the locking block 1341. At this time, the rotor will not rotate, which serves to fix the wire end when the next rotor is wound; Unloading station unlocking: When the station moves to the unloading area, roller 2 13410 disengages from trigger plate 1 1362, spring 3 1349 drives the limiting plate 1346 to reset, releasing the locking block 1341 from the limit. After the placement seat 1331 flips, the rotor falls out of the unloading area under the action of gravity.

[0068] Example 3, referring to Figures 1 to 16 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0069] Specifically, the basic shearing execution structure of the cut-off component 135 realizes the same-direction staggered tangential action. The cut-off component 135 includes: an arc plate 1351, which is set on the side of the base 132, with one base 132 corresponding to four arc plates 1351. The four arc plates 1351 are arranged in a circumferential array around the base 132. The arc plates 1351 are fixedly connected to the base 132 through adjustable elastic telescopic rods, and the arc plates 1351 play a role in guiding and supporting the wire; a first cutter 1352, which is fixed on the arc plate 1351; and a second cutter 1353, which slides on the arc plate 1351. Both the first cutter 1352 and the second cutter 1353 are cemented carbide cutters. The cutting edge is blunted to prevent cutting the wire sheath. The second cutter 1353 and the first cutter 1352 form a staggered shearing pair to complete the cutting of the enameled wire. The third roller 1354 rotates at the lower end of the second cutter 1353 and cooperates with the trigger 136. The third roller 1354 is a wire cutting trigger wheel and cooperates with the trigger plate 1365 to receive the shearing power. The fixed block 1355 is fixed to the surface of the second cutter 1353. The guide rod 1356 slides on the arc plate 1351 and its lower end is fixed to the top of the fixed block 1355. The fixed block 1355 and the guide rod 1356 are the vertical lifting guide transmission structure of the second cutter 1353, which constrains the linear shearing motion of the cutter.

[0070] Specifically, the cutting component 135 also includes: a spring 1357, which is sleeved on the lower end of the guide rod 1356 and has its two ends fixed to the surface of the arc plate 1351 and the surface of the fixing block 1355, respectively. The spring 1357 is an automatic reset elastic element for the cutter 1353, which normally keeps the cutter open; and a T-block 1358, which is fixed on the cutter 1353 and slides on the arc plate 1351. The arc plate 1351 has a vertical hole that moves to cooperate with the T-block 1358. The T-block 1358 and the vertical hole are the anti-disengagement and limiting structure for the cutter 1353, which prevents the cutter from deviating under force and disengaging from the guide rail.

[0071] A through hole 1359 is formed on the arc plate 1351; a bolt 13510 is threadedly connected to the arc plate 1351; a clamping block 13511 slides in the through hole 1359, and the lower end of the bolt 13510 is rotatably connected to the top of the clamping block 13511. Through the setting of the through hole 1359, the bolt 13510 and the clamping block 13511, the end of the wire can be fixed during the initial rotor winding, so that the winding mechanism 12 can smoothly wind the initial rotor and cut it off when it reaches the unloading position.

[0072] Once the rotor carrying the winding is completed, it moves to the unloading position. Roller 3 1354 contacts trigger plate 3 1365 and receives an upward thrust, pushing cutter 2 1353 vertically downward along guide rod 1356. It engages with fixed cutter 1 1352 and cuts the coil lead at the tail of the finished rotor. There is no trigger thrust at non-unloading positions, so the cutter remains open. The connecting wires between positions continue to run normally without being cut. After the cutting is completed, spring 4 1357 rebounds, and the cutter automatically opens and resets.

[0073] Specifically, the trigger element 136 includes: a ring plate 1361, which is movably sleeved on the surface of the base 132; a trigger plate 1362, which is fixed to the top of the ring plate 1361 and cooperates with the roller 13410. The trigger plate 1362 is provided with a trigger working surface to match the movement trajectory of the roller 13410 and control the unlocking sequence of the elastic positioning element 134; a ring plate 1363, which is movably sleeved on the surface of the base 132; a trigger plate 1364, which is fixed to the bottom of the ring plate 1363 and cooperates with the roller 1339. The trigger plate 1364 is provided with a trigger working surface to control the unlocking sequence of the latch 1336 and the rotation sequence of the station element 133. The ring plate 1361 and the ring plate 1363 are fixed to the bearing sleeve 1311 by a support rod.

[0074] A trigger plate 1365 is fixed on the frame 11 by a support rod, and the trigger plate 1365 cooperates with the roller 1354. The trigger plate 1365 is an independent trigger plate for the unloading point, which only controls the tangential action of the cut-off piece 135. A notched bevel gear ring 1366 is fixed on the bearing sleeve 1311 by a support rod, and the notched bevel gear ring 1366 cooperates with the bevel gear 13311. The notched bevel gear ring 1366 has a partially missing tooth structure. Only when the winding process is completed and it reaches the unloading area station, it engages the bevel gear 13311 to drive the placement seat 1331 and the short rod 1333 to rotate and flip. The rotor flips and falls out of the unloading area under the action of gravity. The rotor remains stationary at other stations.

[0075] Specifically, the rotor intermittent actuation mechanism 14 includes: a lifting and rotating assembly 143, which is mounted on the frame 11. The lifting and rotating assembly 143 can perform a combined vertical lifting and low-speed rotation motion, so that the rotating rod 1432 can achieve a combined vertical sliding and circumferential rotation motion; a number of lever plates 141, which are fixed in a linear array on the lifting and rotating assembly 143; and a number of lever bars 142, which are fixed in a linear array on the surface of the lever plates 141 and cooperate with the rotor gap.

[0076] The lifting and rotating assembly 143 includes: several bearing sleeves 1431, arranged in a linear array and fixed to the frame 11; several rotating rods 1432, arranged in a linear array and sliding and rotating within the bearing sleeves 1431; the lower end of the lever 141 is fixed to the upper end of the rotating rod 1432; and a lifting and rotating component 1433, fixed to the lower end of the rotating rod 1432 and the frame 11. The lifting and rotating component 1433 provides lifting and rotating power. This is prior art, and the working principle of this part is also prior art, which can be clearly understood by those skilled in the art. Xiao, without going into details here, the dial plate 141 and the dial bar 142 are the rotor turning execution tools. The dial bar 142 matches the gap of the motor rotor iron core slot. After the rotor is connected to the upper part, the rotor is turned to rotate at a fixed point, and it also plays a role in limiting the rotor to prevent rotation during winding. After one side of the winding is completed, it moves down to disengage from the rotor, then rotates back and moves up to insert into the gap of the rotor iron core slot. After the rotor is connected to the upper part, the rotor is turned to rotate at a fixed point again. This cycle is repeated to achieve multi-sided winding. The rotor is turned intermittently according to the winding process, and it works with the winding head to complete multi-angle and all-round winding.

[0077] The downward pressure anti-rotation mechanism 15 includes: a downward pressure component 151, which is installed on the frame 11. A pressure block 152 and a limit frame 153 are fixed on the downward pressure component 151. The pressure block 152 cooperates with the groove 1321 and the square block 1342. The limit frame 153 cooperates with the seat 132. A discharge frame 16 is fixed on the frame 11. The downward pressure component 151 is a vertical pressing execution mechanism above the frame 11. The pressure block 152 is aligned and presses the upper part of the seat 132 and the groove 1321 to achieve mechanical locking of the entire rotating station. The limit frame 153 is inserted from the outside to surround the limiting seat 132, thus doubly preventing the radial rotation of the station.

[0078] A buffer conveyor is installed below the discharge frame 16. After the unloading station is unlocked, the finished product rotor falls freely, and the finished product winding rotor is collected and conveyed.

[0079] It should be noted that the structure and materials used in this device meet the requirements for use in the enameled wire winding process of motor rotors: the tooling contacting the rotor is made of insulating and wear-resistant engineering plastic to prevent rotor leakage and core impact; the transmission and sliding parts are made of tempered and wear-resistant alloy steel, which is resistant to repeated mechanical impacts and can operate without jamming for a long time; the springs and torsion springs are made of high-temperature fatigue-resistant alloy steel; the cutting tools are made of hard alloy wear-resistant cutting edges; the tolerance level of the transmission and triggering mechanism of the whole machine meets the precision coil winding process standard, the equipment is resistant to interference from copper powder, oil and dust in the workshop, and can be used for long-term continuous automated batch production, meeting the standardized winding processing production standard of small and medium-sized motor rotors.

[0080] In use, the multi-station intermittent cyclic feeding is achieved: the rotary drive 131 relies on the ratchet 1313 to achieve unidirectional intermittent stepping, and the multiple seats 132 are synchronously transported in a ring. Each seat 132 is surrounded by four sets of placement seats 1331. After the rotor is inserted into the insertion hole 1332, the V-shaped elastic block 1341 adaptively clamps and limits the sway during transport. The pressing component 151 descends and presses the seat 132 and the outer side of the limit frame 153 to form a double anti-rotation constraint, and the base does not deviate throughout the winding process.

[0081] Automatic multi-faceted and omnidirectional winding: After the winding station is positioned, the lifting and rotating component 143 drives the lever 142 to lift and insert into the rotor core slot, intermittently rotating the rotor to complete the coil winding face by face. After the lever is completed, it falls back and disengages from the rotor, and the feeding mechanism steps to the next station.

[0082] Sequential linkage elastic clamping switching: When the workstation moves to the processing area, the trigger plate 1362 pushes the limit plate 1346 down to lock the elastic block 1341, and the rotor is rigidly fixed, providing a fixed support point for the previous workpiece wire. After the workstation moves away from the area, the limit plate 1346 resets and restores the elastic floating clamping, which facilitates unloading and flipping.

[0083] Automatic wire cutting at the unloading station, maintaining continuity between workstations: Only when the base 132 moves to the unloading station, the trigger plate 3 1365 pushes the cutter 2 1353 upward to engage with the cutter 1 1352 to cut the finished product tail wire. The cutters at other workstations remain open, and the enameled wire between the front and rear rotors is completely connected, eliminating the need for re-threading and allowing for continuous processing.

[0084] Automatic flipping unloading: The missing bevel gear ring 1366 at the unloading station meshes with the station bevel gear 13311. The trigger plate 1364 unlocks the lever 1336 in advance, causing the placement seat 1331 to flip as a whole. The rotor falls into the discharge frame 16 by its own weight. After the station leaves the meshing area, the tooling automatically springs back to reset and enters the next round of feeding cycle.

[0085] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
