Technical Field

[0001] The present application relates to the technical field of stator winding equipment, and in particular to a triple-block winding machine. Background Art

[0002] The stator is an important part of the motor. It generates a magnetic field by passing electricity, which interacts with the magnetic field of the rotor to realize the rotation of the motor. The purpose of stator block winding is to wind the wire evenly and tightly on the stator block to ensure that the current can flow through the wire and generate the required magnetic field.

[0003] Stator winding equipment is a special equipment used to wind the wire on the stator core, and is one of the important equipment in the motor manufacturing process. Existing stator winding machines usually only wind one set of stators, which has the problems of low efficiency and low automation. Summary of the invention

[0004] In order to improve the winding efficiency of the winding machine, the present application provides a triple block winding machine.

[0005] The present application provides a triple block winding machine adopting the following technical solution:

[0006] A triple block winding machine comprises a workbench, a double-pass mechanism, a grasping mechanism for grasping a stator, a winding mechanism for positioning and placing the stator, and a wire feeding mechanism, wherein the double-pass mechanism is provided with at least three feed troughs arranged at intervals and used for placing the stator, the grasping mechanism is provided with a grasping assembly for grasping a plurality of stators at the same time, and the winding mechanism comprises a winding fixing seat, a winding tool rotatably mounted on the winding fixing seat and used for clamping the stator, and a winding drive source for driving the winding tool to rotate.

[0007] By adopting the above technical scheme, when using the above winding machine for winding, the operator places the stator in the feeding slot of the double-pass mechanism, then starts the grabbing mechanism, grabs the stator and feeds it to the winding tooling of the winding mechanism, starts the wire feeding mechanism, preliminarily clamps the wire and the stator through the winding tooling, starts the winding drive source, winds the winding wire around the stator, repeats the above operation, so that the wire is wound around multiple stators on the winding tooling, and after all the winding is completed, the stator is removed by the grabbing mechanism and placed in the double-pass mechanism, the operator unloads the stator and re-places the stator to be wound. The above winding machine has a high degree of automation and can wind multiple stators at one time, thereby improving the winding efficiency compared to the winding machine in the prior art.

[0008] Optionally, the double-pass mechanism comprises a double-pass fixed plate fixed to the workbench, a double-pass rotating plate rotatably mounted on the double-pass fixed plate, and a double-pass driving member driving the double-pass fixed plate to rotate, and two groups of feeding assemblies are symmetrically arranged on the top of the double-pass rotating plate along the rotation axis;

[0010] By adopting the above technical solution, the operator places the stator in the feed trough, then starts the double-pass drive and horizontally rotates the double-pass rotating plate to facilitate the grabbing mechanism to load and grab the stator. At the same time, after the double-pass rotating plate rotates, the operator can remove the stator that has completed winding in the unloading plate. The setting of the double-pass mechanism realizes the loading and unloading of the stator at the same time, saving working space, reducing costs and improving efficiency.

[0011] Optionally, the grasping mechanism is a transport robot, the grasping assembly is arranged on the output shaft of the transport robot, and the grasping assembly is also provided with a shearing piece for shearing the wire.

[0012] By adopting the above technical solution, the form of the grasping mechanism is specifically disclosed, and the handling robot can complete highly repetitive and labor-intensive tasks in a short time. Compared with manual operation, the speed is faster and the overall efficiency is improved.

[0013] Optionally, the winding tool includes a winding frame body connected to the winding drive source, a plurality of clamping assemblies for clamping the stator, a linkage assembly for driving the clamping assemblies to slide, and a locking assembly for locking the clamping assemblies.

[0014] By adopting the above technical solution, the stator is fixed in the winding tooling by the clamping assembly. When winding, one group of the clamping assemblies is pushed out through the linkage assembly, so that this group of clamping assemblies is staggered with the remaining clamping assemblies, and all the clamping assemblies are locked at the same time by the locking assembly. Finally, the winding drive source is started to drive the entire winding frame to rotate, thereby realizing the winding of the wire on the stator.

[0015] Optionally, the clamping assembly includes a clamping seat and a clamping abutment slidably mounted on the winding frame body, the clamping seat has a clamping groove for inserting the stator, one end of the clamping abutment is connected to the clamping groove, and when the stator is inserted into the clamping groove, the linkage assembly pushes the clamping abutment so that the clamping abutment is pressed against the stator.

The grasping mechanism inserts the stator feed into the clamping groove, and then drives the clamping abutment to move toward the stator, so that the stator is clamped tightly against the clamping groove, thereby achieving the fixation of the stator on the winding tooling, the clamping operation is simple, and the clamping effect is stable.

[0017] Optionally, the linkage assembly includes a linkage rod, a linkage fixing plate for fixing two ends of the linkage rod, a linkage sleeve fixed to the linkage fixing plate, a sliding rod slidably matched with the linkage sleeve, and a pushing member for pushing the linkage fixing plate;

[0019] By adopting the above technical scheme, the specific structure of the linkage component is disclosed, and the linkage rod penetrates the connecting columns of multiple clamping abutments together, so that when the pushing member pushes the linkage fixing plate, it can drive the multiple clamping abutments to move toward the stator, and complete the clamping work of multiple stators at the same time. At the same time, the arrangement of the strip holes enables the grabbing component to move one group of clamping components as a whole away from the winding frame body, complete the interlacing of a single group of clamping components with the remaining clamping components, and facilitate the winding of the wire.

[0020] Optionally, the pushing member includes a first pushing plate and a second pushing plate respectively slidably disposed on opposite side walls of the winding fixing seat, the linkage fixing plate has a first abutting plate and a second abutting plate corresponding to the pushing member, the first pushing plate and the first abutting plate are abutted and matched, and the second pushing plate and the second abutting plate are cross-hooked;

[0021] An extension plate is also provided on the linkage fixing plate, and a buffer spring is fixedly provided between the extension plate and the winding frame body.

[0022] By adopting the above technical solution, the specific structure of the pusher is disclosed. When the stator is inserted into the clamping groove or the stator is wound, the pusher is activated to clamp or loosen the stator by the clamping abutment frame.

[0023] The first push plate and the first abutment plate are in abutment cooperation, so when the clamping abutment frame is abutted, the first push plate is started, and the linkage assembly is driven to move toward the clamping seat as a whole through the first push plate; the second push plate and the second abutment plate are cross-connected, so when the first push plate is pushed, the second push plate can be driven to move synchronously, and the second push plate and the second abutment plate are always in a hooked state. After the winding of the stator is completed, the second push plate is started to drive the linkage assembly to move away from the clamping seat as a whole, thereby releasing the clamping of the stator;

[0024] The arrangement of the pushing plate and the abutting plate improves the clamping efficiency of the clamping assembly and has little effect on the rotational winding of the winding frame body.

[0026] By adopting the above technical scheme, the structural composition of the locking assembly is disclosed, and the arrangement of the locking plate and the locking rod enables multiple groups of clamping assemblies to be always in a locked state. When the pushing rod drives one group of clamping assemblies to be pushed out, the locking plate is first slid through the locking push plate to move the locking rod to the connecting hole, and then the clamping assembly is pulled by the pushing rod to move the locking rod from the first locking hole to the second locking hole, and the locking push plate is reset, the locking plate is automatically reset, and all the clamping assemblies are clamped again.

[0027] Optionally, a clamping assembly for clamping the wire is further provided on the winding frame body, and the clamping assembly includes a clamping drive member and a clamping plate connected to the output shaft of the clamping drive member.

[0028] By adopting the above technical solution, the setting of the clamping assembly can have a clamping effect on the wires inserted into the stator, ensuring that the wires are tightly wound on the stator, reducing the gaps between the wires, and optimizing the distribution of the electromagnetic field.

[0029] Optionally, the wire feeding mechanism includes a wire feeding assembly and a moving assembly, the wire feeding assembly is provided with a wire feeding head corresponding to the winding mechanism, the wire feeding head is arranged on the moving assembly, and the moving assembly includes a vertical lifting module, a first horizontal module, a second horizontal module and a rotating module for driving the wire feeding head to rotate.

[0047] The following is combined with Figure 1-10 This application is described in further detail.

[0048] The embodiment of the present application discloses a triple block winding machine.

[0049] Reference Figure 1 A triple block winding machine comprises a workbench 1, on which are mounted a double-pass mechanism 2 for stator feeding and unloading, a grabbing mechanism 3 for grabbing the stator, a winding mechanism 4 for winding, and a wire feeding mechanism 5 for feeding the wire to the winding mechanism 4.

[0050] Reference Figure 1 and Figure 2 The double-pass mechanism 2 includes a double-pass fixed plate 21, a double-pass rotating plate 22, a double-pass driving member 23, a feeding assembly 24 and a blanking plate 25. The double-pass fixed plate 21 is fixed to the workbench 1 by bolts, and a rotating seat 211 for rotating the double-pass rotating plate 22 is installed on the top of the double-pass fixed plate 21. The double-pass driving member 23 is a rotating motor, and its output shaft and the rotating shaft of the double-pass rotating plate 22 are driven by gears.

[0051] The feed assembly 24 is symmetrically arranged along the rotation axis of the double-pass rotating plate 22 , and includes a feed seat 241 fixed to the double-pass rotating plate 22 , a feed rotating shaft 242 rotatably mounted on a feed block 243 , and a feed block 243 fixed to the feed rotating shaft 242 .

[0052] The feed seat 241 is in the shape of a rectangular block as a whole, and the feed rotating shaft 242 and the length direction of the feed seat 241 are arranged in parallel. A rotating motor driving the feed rotating shaft 242 is fixed to the side wall of the feed seat 241. The rotation of the feed rotating shaft 242 facilitates the operator to load the stator, and at the same time facilitates the grasping mechanism 3 to grasp the stator. The feed block 243 is fixed to the feed rotating shaft 242 by bolts, and a feed groove 2431 for positioning and inserting the stator is provided on the feed block 243. Two groups of unloading plates 25 are also provided, which are fixed to the side of the feed seat 241 close to each other. The top of the unloading plate 25 is provided with an unloading groove 251 for horizontal placement of the stator.

[0053] Reference Figure 1 and Figure 3 , the gripping mechanism 3 is a six-joint handling robot of the prior art, so the specific structure is not described in this application. A gripping assembly 31 for grasping the stator is installed on the gripper of the handling robot. The gripping assembly 31 includes a gripping plate 311 and a gripping member 312 fixed on the gripping plate 311. The gripping member 312 grasps the stator through the principle of electromagnet adsorption. When the gripping plate 311 and the feed seat 241 correspond, the gripping member 312 is energized to generate magnetic force, so that the stator is adsorbed onto the gripping member 312. Among them, a connecting plate 313 extending toward the gripping mechanism 3 is also fixedly installed at the end of the gripping plate 311, and a shearing member 314 for cutting the wire is fixed on the connecting plate 313. The shearing member 314 is a pneumatic scissors in the prior art.

[0054] Reference Figure 4 and Figure 5 The winding mechanism 4 includes a winding fixing seat 41 fixed to the top surface of the workbench 1, a winding tool 42 rotatably mounted on the winding fixing seat 41, and a winding driving source 43 for driving the winding tool 42 to rotate. The winding driving source 43 is a rotary motor, whose output shaft is connected to a winding rotating disk 431 through a gear belt drive, and the winding tool 42 is fixed to the winding rotating disk 431.

[0055] The winding tool 42 includes a winding fixing plate 421 disposed on the winding rotating disk 431 and a winding frame body 422 disposed on the side of the winding fixing plate 421 away from the winding rotating disk 431. The winding fixing plate 421 and the winding rotating disk 431 as well as the winding fixing plate 421 and the winding frame body 422 are fixed by bolts. The winding fixing plate 421 is a rectangular plate as a whole, and the winding frame body 422 is a rectangular frame body. The length directions of the two are parallel, and the length of the winding frame body 422 is smaller than the winding fixing plate 421.

[0056] The winding tool 42 is equipped with a plurality of clamping assemblies 44 for clamping the stator, a linkage assembly 45 for driving the clamping assembly 44 to slide, a locking assembly 46 for locking the clamping assembly 44, and a pressing assembly 47 for pressing the wire.

[0057] The clamping assemblies 44 are evenly arranged along the length direction of the winding frame body 422. In this embodiment, the winding tool 42 has three groups of evenly arranged clamping assemblies 44. The clamping assemblies 44 are integrally slidably mounted on the winding frame body 422. The clamping assemblies 44 include a clamping seat 441 and a clamping abutment 442 that slidably cooperates with the clamping seat 441. The clamping seat 441 has a clamping groove 4411 for inserting the stator.

[0058] The clamping abutment 442 includes an abutment rod 4421 and a connection column 4422 connected to the abutment rod 4421. The clamping seat 441 has a sliding chamber 4412 for the abutment rod 4421 to slide. Both ends of the sliding chamber 4412 are connected to the outside, and one end of the sliding chamber 4412 is open and connected to the clamping groove 4411. The abutment rod 4421 is located on the side of the sliding chamber 4412 facing the clamping groove 4411, and the abutment rod 4421 extends from the opening at one end of the sliding chamber 4412, so that the abutment rod 4421 is tightly pressed against the stator to achieve clamping and fixing of the stator.

[0059] Combination Figure 6 One end of the connecting column 4422 is fixed to the side of the abutting rod 4421 away from the clamping groove 4411. The connecting column 4422 is sleeved with a return spring 4423 in the sliding chamber 4412. The two ends of the return spring 4423 respectively abut against the inner wall of the sliding chamber 4412 and the abutting rod 4421. The other end of the connecting column 4422 passes through the opening on the other side of the sliding chamber 4412 and is integrally provided with a matching column 4424 for matching with the linkage assembly 45.

[0060] When winding, one group of clamping components 44 is pulled out from the winding frame body 422 through the grasping mechanism 3, so that the pulled out stator and the stators on the remaining clamping components 44 are in a staggered state. Then the winding drive source 43 is started to drive the rotation of the winding frame body 422. In order to facilitate the pulling of the clamping components 44, the opposite side walls of the clamping seat 441 are also provided with a push groove 4413, and the L-shaped pull rod 315 on the grasping plate 311 is used to cooperate with the push groove 4413. When pulling, the winding frame body 422 is first rotated to a vertical state (parallel in the length direction and the height direction), and then the L-shaped pull rod 315 is extended between the adjacent clamping seats 441, and the L-shaped pull rod 315 corresponds to the end of the push groove 4413, and the horizontal pulling out and pushing in of the clamping component 44 is realized by the handling robot.

[0061] Reference Figure 7 and Figure 8 The linkage assembly 45 includes a linkage rod 451, a linkage fixing plate 452 fixed at both ends of the linkage rod 451, a linkage sleeve 453 arranged on the linkage fixing plate 452, a sliding rod 454 slidingly cooperated with the linkage sleeve 453, and a pushing member 455 for pushing the linkage fixing plate 452.

[0062] The linkage rod 451 and the winding frame body 422 are arranged in parallel, and both ends of the linkage rod 451 penetrate the side wall in the width direction of the winding frame body 422. The winding frame body 422 has a sliding groove 4221 for the linkage rod 451 to slide, and the sliding direction of the linkage rod 451 is parallel to the length direction of the connecting column 4422. The matching columns 4424 of the plurality of clamping assemblies 44 all have a strip hole 4425 for the linkage rod 451 to pass through, and the extension direction of the strip hole 4425 is parallel to the sliding direction of the linkage rod 451.

[0063] The linkage fixing plate 452 is located on both sides of the winding frame body 422, and is fixed by bolts and the end of the linkage rod 451. The linkage sleeve 453 is bolted to the linkage fixing plate 452, and the two ends of the sliding rod 454 are respectively fixed to the winding frame body 422 and the winding fixing plate 421. When the linkage fixing plate 452 slides, it can drive the linkage rod 451 to slide synchronously, and then realize the sliding of the matching column 4424 through the linkage rod 451, and press the clamping abutment 442 against the stator side wall. Among them, an extension plate 456 is fixed on the upper ring of the linkage fixing plate 452, and a fixing column 4561 is provided on the extension plate 456 and the winding frame body 422, and a buffer spring 457 is installed between the two fixing columns 4561.

[0064] The pusher 455 includes a first push plate 4551 and a second push plate 4552 respectively disposed on opposite sides of the winding fixed seat 41. Both push plates are slidable in the horizontal direction by a cylinder. The linkage fixing plates 452 on opposite sides of the winding frame body 422 have a first abutment plate 458 corresponding to the first push plate 4551 and a second abutment plate 459 corresponding to the second push plate 4552.

[0065] The first push plate 4551 and the second push plate 4552 both have a first hook 4553 at their ends, and the first hook 4553 both extend toward the rotation axis of the bobbin body 422. The first abutment plate 458 and the second abutment plate 459 both have a second hook 4591 that matches the first hook 4553 at their ends, and the second hooks 4591 of the two abutment plates both extend away from the rotation axis of the bobbin body 422. The first push plate 4551 and the first abutment plate 458 are in abutment with each other, and the second push plate 4552 and the second abutment plate 459 are hooked with each other. The winding frame body 422 is rotated to a horizontal state (the length direction of the winding frame body 422 is parallel to the horizontal direction). After the stator is inserted into the clamping groove 4411, the first push plate 4551 is started to push the linkage fixing plate 452 on one side toward the clamping groove 4411, so that the clamping abutment column is pressed against the stator; the second push plate 4552 and the second abutment plate 459 are cross-connected, so the second push plate 4552 is also pushed synchronously. When the stator winding is completed and the clamping needs to be released, the second push plate 4552 is started to push the linkage fixing plate 452 on the other side away from the clamping groove 4411, so that the linkage rod 451 is driven to move synchronously, thereby realizing the separation of the clamping abutment column and the stator.

[0066] Reference Figure 4 and Fig. 9 The locking assembly 46 includes a locking plate 461 slidably mounted on the outer wall of the winding frame body 422 and a locking push plate 462 for pushing the locking plate 461. The locking plate 461 is a rectangular plate arranged parallel to the winding frame body 422. The winding frame body 422 has a T-shaped slide groove for the locking plate 461 to slide, and both ends of the T-shaped slide groove penetrate the outside. A locking convex plate 4611 is extended from one end of the locking plate 461 for the locking push plate 462 to push, and a compression spring 463 for resetting is fixed to the other end.

[0067] The locking plate 461 is provided with locking holes corresponding to the clamping assembly 44 at intervals. The locking holes include a first locking hole 4612, a second locking hole 4613 and a connecting hole 4614. The locking hole is U-shaped as a whole, and the opening of the U-shape faces the compression spring 463. The clamping seat 441 has a locking rod 4414 inserted into the locking hole. Through the action of the compression spring 463, the locking hole is in the first locking hole 4612 or the second locking hole 4613. At this time, the clamping assembly 44 is in a locked state and cannot slide in the horizontal direction.

[0068] The locking push plate 462 is vertically fixed to the winding fixed seat 41, and the locking push plate 462 is driven by pushing the cylinder. When the winding frame body 422 is in a vertical state, the locking push plate 462 and the locking convex plate 4611 correspond to each other, and the locking push plate 462 is started, so that the locking plate 461 moves upward as a whole, so that the locking rod is in the connecting hole 4614, and the clamping components 44 are all in an unlocked state. The gripping mechanism 3 pulls or pushes one group of the clamping components 44. After the pulling or pushing is completed, the locking push plate 462 is reset, and the locking plate 461 is automatically reset under the action of the compression spring 463, so that the clamping components 44 are locked again, ensuring the stability of the clamping components 44 when the winding frame body 422 rotates.

[0069] The clamping assembly 47 is fixed to the clamping seat 441 as a whole, and includes a clamping drive 471 and a clamping plate 472 connected to the output shaft of the clamping drive 471. The clamping drive 471 is a push cylinder of the prior art, and its output direction is parallel to the insertion direction of the stator. The clamping plate 472 and the clamping groove 4411 are arranged correspondingly, and when the wire moves to the stator, the wire is first clamped and fixed by the clamping plate 472.

[0070] Reference Fig.10 In order to collect the sheared wire waste, a recovery component 6 corresponding to the winding tool 42 is also provided on the workbench 1. The recovery component 6 includes a recovery channel 61 and a recovery frame 62. The recovery channel 61 is fixed to the top surface of the workbench 1 by bolts, and one end of the recovery channel 61 corresponds to the side of the winding frame body 422 away from the winding fixing plate 421. After the stator is wound, the shearing piece 314 shears and separates the wire pressed by the clamping component 47 and the wire wound by the stator, and then releases the lock of the clamping component 47, so that the wire waste automatically falls into the recovery channel 61 and slides into the recovery frame 62.

[0071] The wire feeding mechanism 5 is integrally arranged on the side of the winding mechanism 4 away from the double-pass mechanism 2, and the wire feeding mechanism 5 includes a wire feeding assembly 51 and a moving assembly 52. ​​The wire feeding assembly 51 includes a plurality of wire feeding rollers and a wire feeding head 511 arranged on the moving assembly 52. ​​In this embodiment, the wire feeding mechanism 5 has two sets of wire feeding assemblies 51, so two parallel wires are passed through the wire feeding head 511.

[0072] The moving assembly 52 is used to move the wire feeding head 511 so that the wire can be stably and tightly wound on the stator. The moving assembly 52 includes a vertical lifting module 521, a first horizontal module 522, a second horizontal module 523 and a rotating module 524. The vertical lifting module 521 is arranged on the workbench 1, and it realizes lifting and lowering by the principle of the motor screw in the prior art. Both horizontal modules are motor linear modules in the prior art. The first horizontal module 522 is fixed to the lifting platform of the vertical lifting module 521, and its moving direction is parallel to the width direction of the winding frame body 422. The second horizontal module 523 is fixed to the slide plate of the first horizontal module 522, and its moving direction is perpendicular to the first horizontal module 522. The rotating module 524 is fixed to the slide plate of the second horizontal module 523. The rotating module 524 is matched with the motor gear to realize the rotation of the wire feeding module.

[0073] The implementation principle of a triple-block winding machine in the embodiment of the present application is as follows: the operator inserts the stator into the feed slot 2431 of the feed block 243, starts the double-pass drive member 23, rotates the stator to the side close to the gripping mechanism 3, and at the same time, the operator takes the wound stator out of the unloading plate 25;

[0074] The handling robot uses the gripping mechanism 3 to absorb and move the stator to the winding mechanism 4, so that the stator is inserted into the clamping groove 4411, and the first push plate 4551 is started to drive the linkage rod 451 to move toward the stator, so that the clamping rod is pressed against the stator, and the clamping assembly 44 fixes the stator;

[0075] When winding begins, the winding frame body 422 is first rotated to a vertical state, and the locking push plate 462 is started, so that the locking plate 461 moves upward, and the multiple groups of clamping assemblies 44 are all in an unlocked state. The handling robot pulls one group of clamping assemblies 44 out of the winding frame body 422 through the cooperation of the L-shaped pull rod 315 and the pushing groove 4413, so that the pulled out stator and the remaining stators are staggered, and the locking push plate 462 is reset, so that the locking plate 461 is reset under the compression spring 463 and the clamping assembly 44 is locked again;

[0076] The moving assembly 52 moves the wire to one side of the stator, and clamps one end of the wire through the clamping assembly 47, and then starts the winding drive source 43 to drive the clamping assembly 44 to rotate, so that the wire is wound on the stator. When the stator rotates, the moving assembly 52 also drives the wire feeding head 511 to perform vertical lifting, horizontal movement in two directions, and horizontal rotation.

[0077] After completing the winding of one group of stators, the end of the wire on the stator is sheared by the shearing piece 314; the winding frame body 422 is rotated to a vertical state, the pulled-out clamping assembly 44 is pushed back in, and then another group of unwound clamping assemblies 44 are pulled out; the above operation is repeated until the winding of three groups of stators is completed, the winding frame body 422 is rotated to a horizontal state again, and the linkage rod 451 is moved away from the stator by the second push plate 4552 to release the clamping of the stator, and the grabbing assembly 31 adsorbs and moves the stator to the blanking plate 25 of the double-pass mechanism 2.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
