Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to an opening and closing mechanism and a stator winding machine. Background Technology

[0002] With increasingly higher requirements for power source motors, the requirements for motor winding are also becoming more stringent. During the winding process, since the winding slots are closely adjacent along the circumferential direction and the iron cores between the slot openings are arranged radially, the copper wire may be mis-wound onto the iron core of the adjacent non-winding area when winding a specific slot due to the small distance between adjacent slot openings. If the wire is then removed, it may cause damage to the stator, affecting the stator winding efficiency and motor performance. Utility Model Content

[0003] The main purpose of this invention is to propose an opening and closing mechanism to solve the technical problem that copper wires are easily mistakenly wound into non-winding areas during stator winding.

[0004] To achieve the above objectives, the opening and closing mechanism proposed in this utility model includes:

[0005] The mounting base has a buffer space for placing a workpiece.

[0006] Two support components are provided, and the two support components are rotatably mounted on the mounting base. Each support component has a positioning part.

[0007] A driving component is movably disposed on the mounting base, and one driving component is correspondingly provided for each of the supporting components; and

[0008] A transmission assembly is movably mounted on the mounting base. The drive assembly is driven to rotate the corresponding support assembly via the transmission assembly, so that the support assembly has a first position and a second position. In the first position, the two support assemblies are close together to cover the outer periphery of the buffer position, and there is a certain interval between the positioning portions of the two support assemblies to form a processing position. In the second position, the two support assemblies are far apart so that the buffer position is exposed.

[0009] In one embodiment, the opening and closing mechanism further includes a rotating component, which includes a fixed end and a rotating end. The fixed end is fixedly disposed on the mounting base, and the rotating end is rotatably disposed on the fixed end. The end of any of the transmission components away from the drive component is rotatably connected to the rotating end, so that the transmission component rotates about the rotating component as an axis. Each of the holding components is disposed on the corresponding transmission component.

[0010] In one embodiment, the transmission assembly includes:

[0011] The first connecting plate has a first end and a second end at two ends, the first end being rotatably connected to the output end of the driving component, and the second end being connected to the rotating component.

[0012] The second connecting plate is disposed on the first connecting plate, and the supporting component is disposed on the end of the second connecting plate away from the first connecting plate.

[0013] In one embodiment, the opening and closing mechanism further includes a support frame disposed on the mounting base. The support frame includes two mounting positions arranged from top to bottom, and each of the drive components is rotatably disposed in one of the mounting positions.

[0014] In one embodiment, the support component includes:

[0015] Mounting plate, located on the second connecting plate;

[0016] A core protector is disposed on the mounting plate, and the core protector is bent in a bent state to extend toward another support component, with the ends of the two core protectors close to each other configured as the positioning portion.

[0017] In one embodiment, the opening and closing mechanism further includes a first limiting structure. Two first limiting structures are provided, both of which are located on the mounting base. At the first position, the first limiting structure abuts against the support component to limit the rotation of the support component.

[0018] In one embodiment, the opening and closing mechanism further includes a second limiting structure, which is disposed on the mounting base and located between the two transmission components. In the second position, the transmission component abuts against the second limiting structure to limit the rotation of the holding component.

[0019] In one embodiment, the opening and closing mechanism further includes a detection component disposed on the mounting base and used to detect whether the buffer position carries a workpiece.

[0020] In one embodiment, the opening and closing mechanism further includes a support component, which is disposed on the mounting base. The support component includes a rotation drive and a support member, and the buffer position is configured as the support member. The rotation drive is driven to the support member to drive the support member to rotate.

[0021] This utility model also proposes a stator winding machine, including the opening and closing mechanism as described in any of the above claims.

[0022] In the technical solution of this utility model, a buffer position for supporting workpieces such as stators is provided on the mounting base, and a driving component is also provided. The driving component is connected to the holding component through a transmission component, so that the holding component can rotate on the mounting base. When the two holding components rotate to the first position, the holding components are located in front of the buffer position and close to each other. The interval between the positioning parts of the two holding components is the processing position, so that one of the iron cores of the stator is exposed at the processing position. The exposed part of the stator is waiting for winding processing. By shielding other parts of the stator by the holding components, winding can be avoided. Winding the wire to other areas affects motor performance and wastes enameled wire. When the two holding components rotate to the second position, they rotate in the opposite direction, increasing the distance between their positioning parts. At this point, the entire buffer position is exposed, providing sufficient space for the stator to be picked up and put in. This facilitates the removal of finished stators and other workpieces and the placement of unwound stators and other workpieces. Through the cooperation of the drive component, transmission component, and holding component, the holding components can be opened and closed quickly to provide surrounding space for the stator carried on the buffer position, preventing copper wire from being mis-wound.

[0044] With increasingly higher requirements for power source motors, the requirements for motor winding are also becoming more stringent. During the winding process, since the winding slots are closely adjacent along the circumferential direction and the iron cores between the slot openings are arranged radially, the copper wire may be mis-wound onto the iron core of the adjacent non-winding area when winding a specific slot due to the small distance between adjacent slot openings. If the wire is then removed, it may cause damage to the stator, affecting the stator winding efficiency and motor performance.

[0045] This utility model proposes an opening and closing mechanism and a stator winding machine.

[0046] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the opening and closing mechanism includes:

[0047] Mounting base 100 has a buffer space for placing workpieces;

[0048] Two support components 200 are provided, and the two support components 200 are rotatably mounted on the mounting base 100. Each support component 200 has a positioning part.

[0049] Drive component 300, movably mounted on mounting base 100, one drive component 300 corresponding to each support component 200; and

[0050] The transmission assembly 400 is movably mounted on the mounting base 100. The drive assembly 300 is driven to the corresponding support assembly 200 through the transmission assembly 400 to drive the support assembly 200 to rotate, so that the support assembly 200 has a first position and a second position. In the first position, the two support assemblies 200 are close together to cover the outer periphery of the buffer position, and there is a certain interval between the positioning parts of the two support assemblies 200 to form a processing position. In the second position, the two support assemblies 200 are far apart so that the buffer position is exposed.

[0051] In the technical solution of this utility model, a buffer position for supporting workpieces such as the stator 10 is provided on the mounting base 100, and a driving component 300 is also provided. The driving component 300 is connected to the supporting component 200 through a transmission component 400, so that the supporting component 200 can rotate on the mounting base 100. When the two supporting components 200 rotate to the first position, such as Figure 2 As shown, the support assembly 200 is located in front of and close to the buffer position. The interval between the positioning parts of the two support assemblies 200 is the processing position, so that one of the iron cores of the stator 10 is exposed at the processing position. The exposed part of the stator 10 awaits winding processing. By shielding the other parts of the stator 10 with the support assembly 200, it is possible to prevent the winding from going to other areas, affecting the motor performance and causing waste of enameled wire. When the two support assemblies 200 rotate to the second position, as... Figure 1 The two support components 200 shown rotate in a direction away from each other, and the distance between the positioning parts of the two support components 200 increases. At this time, the entire buffer position is exposed, providing sufficient space for the stator 10 to be picked up and put in. This makes it easy to remove the finished stator 10 and other workpieces and put in the unwound stator 10 and other workpieces. Through the cooperation of the drive component 300, the transmission component 400 and the support component 200, the support component 200 can be opened and closed quickly to provide surrounding space for the stator 10 carried on the buffer position and avoid the copper wire from being miswound.

[0052] Specifically, the workpiece in this application is a stator 10. The following description uses the stator 10 as an example. The stator 10 includes multiple iron cores arranged circumferentially. When winding the stator 10, each iron core needs to be wound individually until all iron cores are wound. However, because adjacent iron cores are close together, when winding each iron core individually, it may be interfered with by other iron cores, causing the enamel wire to be wound onto other iron cores, affecting the motor's performance. In this embodiment, the drive assembly 300 includes a fixed part and a telescopic part. The fixed part is rotatably mounted on the mounting base 100. The telescopic part can extend and retract relative to the fixed part. The telescopic part is rotatably connected to a transmission assembly 400 and connected to a support assembly 200 through the transmission assembly 400. When the telescopic part extends, it drives the transmission assembly 400 to rotate, thereby causing the support assembly 200 to rotate. The two support assemblies 200 rotate towards each other. The movement continues until the two support components 200 rotate to the front of the buffer position, forming a certain gap at the front, which is the processing position. One of the iron cores of the stator 10 is exposed at the processing position, while the other iron cores are covered by the support components 200. The winding structure winds the exposed iron core at the processing position. After the iron core is wound, the stator 10 is rotated so that the next iron core rotates to the processing position, and then the iron core is wound again until all the iron cores are wound. Since the support components 200 cover all the other iron cores and only expose one iron core, the copper wire can be prevented from being mistakenly wound onto other adjacent iron cores during winding, reducing copper wire waste and improving winding efficiency. Since each support component 200 is correspondingly provided with a drive component 300 and a transmission component 400, each support component 200 rotates to adjust the coverage area, reducing the space occupied.

[0053] In one embodiment, the drive assembly 300 can be a linear drive such as a cylinder, hydraulic cylinder, or electric telescopic rod, without limitation. In this embodiment, the drive assembly 300 uses a cylinder. The rotation and opening of the support assembly 200 are achieved by extending and retracting the piston rod of the cylinder, which is a simple implementation. In one embodiment, a sensor is provided on the cylinder to sense whether the piston rod is currently extended or retracted, in order to determine the position state of the support assembly 200 at this time.

[0054] Please refer to Figure 5 In an embodiment of this utility model, the opening and closing mechanism further includes a rotating component 500. The rotating component 500 includes a fixed end and a rotating end. The fixed end is fixedly disposed on the mounting base 100, and the rotating end is rotatably disposed on the fixed end. The end of any transmission component 400 away from the drive component 300 is rotatably connected to the rotating end, so that the transmission component 400 rotates about the rotating component 500 as the axis. Each holding component 200 is disposed on the corresponding transmission component 400.

[0055] Specifically, such as Figure 5As shown, the rotating assembly 500 includes a mounting sleeve 550, a first bearing 510, a second bearing 520, a connecting seat 530, and a rotating shaft 540. The fixed end is configured as the mounting sleeve 550, and the rotating end includes the first bearing 510, the second bearing 520, the connecting seat 530, and the rotating shaft 540. The mounting sleeve 550 is fixedly mounted on the mounting seat 100. The connecting seat 530 is rotatably mounted on the mounting sleeve 550 via the first bearing 510, allowing it to rotate along the mounting sleeve 500. The second bearing 520 is disposed inside the connecting seat 530, and the rotating shaft 540 is rotatably connected to the connecting seat 530 via the second bearing 520, meaning the rotating shaft 540 can rotate arbitrarily relative to the connecting seat 530. The two transmission components 400 are rotatably connected at one end to the corresponding telescopic part. The other end of one transmission component 400 is fixed on the connecting seat 530, and the end of the other transmission component 400 away from the drive component 300 is fixed on the rotating shaft 540. That is, one transmission component 400 can rotate around the connecting seat 530, and the other transmission component 400 rotates around the rotating shaft 540. In other words, both transmission components 400 can rotate arbitrarily around the rotating component 500. The extension and retraction of the telescopic part on the drive component 300 drives the transmission component 400 to rotate around its rotation axis, thereby opening or closing the holding component 200 on the transmission component 400.

[0056] Please refer to Figure 3 and Figure 4 In an embodiment of this utility model, the transmission assembly 400 includes:

[0057] The first connecting plate 410 has a first end and a second end at its two ends, the first end of which is rotatably connected to the output end of the drive component 300, and the second end of which is connected to the rotating component 500.

[0058] The second connecting plate 420 is disposed on the first connecting plate 410, and the supporting component 200 is disposed on the end of the second connecting plate 420 away from the first connecting plate 410.

[0059] Specifically, the transmission assembly 400 includes a first connecting plate 410 and a second connecting plate 420. The first connecting plate 410 is rotatably connected to the output end of the corresponding drive assembly 300 via a rotating shaft, and the other end is rotatably connected to the mounting base 100 via a rotating assembly 500. The second connecting plate 420 includes a plate one and a plate two. The plate one fits against the first connecting plate 410 and is mounted on the first connecting plate 410 by screws. The plate two is arranged perpendicularly to the plate one. The support assembly 200 is mounted on the plate two. In one embodiment, the second connecting plate 420 is provided with an elongated hole. The screw passes through the elongated hole and is screwed to the first connecting plate 410. The elongated hole can adjust the relative position of the second connecting plate 420 on the first connecting plate 410 so as to better close and protect the stator 10 core.

[0060] In one embodiment, such as Figure 4 As shown, two drive components 300 are arranged crosswise. The output end of each drive component 300 is connected to a U-shaped connecting frame 310. A first connecting plate 410 is rotatably connected to this connecting frame 310 via a rotating shaft. Since one end of each of the two drive components 400 is connected to the rotating component 500, the two drive components 400 are arranged at an angle. Taking one set as an example, the telescopic portion of the drive component 300 extends, and the first connecting plate 410 rotates along its second end, causing the supporting component 200 to rotate. Since the supporting component 200 is mounted on the first connecting plate 410 via the second connecting plate 420, when the first connecting plate 410 rotates, the second connecting plate 420 and the supporting component 200 also rotate accordingly. The rotation directions are the same, but since the two drive components 300 are intersecting, that is, the extension and retraction directions of the output ends are at an angle, and the two transmission components 400 are at an angle, when the extension and retraction end of the drive component 300 extends, the two holding components 200 rotate towards the closing direction, and the angle between the two transmission components 400 increases, realizing the closing of the two holding components 200. As the first end rotates, the angle between the first end and the drive component 300 changes, that is, the first end rotates relative to the drive component 300 through the rotating shaft. It can be understood that when the extension and retraction parts of the two drive components 300 retract, the angle between the two transmission components 400 decreases, and at this time the angle and distance between the two holding components 200 increase.

[0061] Please refer to Figure 1 and Figure 3 In an embodiment of this utility model, the opening and closing mechanism further includes a support frame 600, which is disposed on the mounting base 100. The support frame 600 includes two mounting positions arranged from top to bottom, and each drive component 300 is rotatably disposed in one mounting position.

[0062] Specifically, the support frame 600 includes a vertical plate 610, which is vertically mounted on the mounting base 100. A first horizontal plate 620, a second horizontal plate 630, and a third horizontal plate 640 are arranged vertically on the vertical plate 610 at intervals, arranged sequentially from top to bottom. The third horizontal plate 640 is mounted against the mounting base 100. A mounting position is formed between the first horizontal plate 620 and the second horizontal plate 630, and another mounting position is formed between the second horizontal plate 630 and the third horizontal plate 640. The fixed part of one of the drive components 300 is rotatably connected to the upper and lower first mounting plates 210 and the second mounting plate 210 via a rotating shaft. Similarly, the fixed part of the other drive component 300 is rotatably connected to the upper and lower second mounting plates 210 and the third mounting plate 210 via a rotating shaft. This facilitates the rotation of the drive component 300 when the drive transmission component 400 rotates, so that the drive component 300 will also rotate accordingly to better drive the support component 200 to rotate.

[0063] Please refer to Figure 4 In an embodiment of this utility model, the support component 200 includes:

[0064] Mounting plate 210 is disposed on second connecting plate 420;

[0065] The core protector 220 is provided on the mounting plate 210, and the core protector 220 and the mounting plate 210 are bent to extend toward another support component 200. The ends of the two core protectors 220 that are close to each other are configured as positioning parts.

[0066] Specifically, as shown in the figure, the mounting plate 210 is mounted on the plate 2 by screws, and the core protector 220 is located at the end of the mounting plate 210 away from the plate 2, and the core protector 220 is perpendicular to the mounting plate 210. The two core protectors 220 are bent and extended toward each other respectively. In one embodiment, the core protector 220 is arc-shaped so that it can better cover the outer periphery of the buffer position in the first position, and there is a certain gap between the two core protectors 220 to form a processing position so that one of the stator 10 cores is exposed and waiting for winding.

[0067] Please refer to Figure 2 and Figure 3 In an embodiment of this utility model, the opening and closing mechanism further includes a first limiting structure 700. Two first limiting structures 700 are provided, and both are provided on the mounting base 100. At the first position, the first limiting structure 700 abuts against the holding component 200 to limit the rotation of the holding component 200.

[0068] Specifically, each support component 200 is provided with a first limiting structure 700. The first limiting structure 700 includes a baffle 701 and a first buffer 702. The baffle 701 is vertically mounted on the mounting base 100, and the first buffer 702 is mounted on the baffle 701 and faces one side of the support component 200. When the telescopic part of the drive component 300 extends, the drive transmission component 400 rotates until the first connecting plate 410 abuts against the first buffer 702. At this time, the transmission component 400 can no longer rotate, and the drive component 300 stops extending. The other drive component 300 is similar. After stopping rotation, the support component 200 is exactly in the first position, forming a processing position for one of the stator 10 cores to be exposed. The setting of the first limiting structure 700 facilitates precise positioning, avoids excessive rotation, avoids damage to the support component 200, and avoids affecting processing efficiency. The second buffer can be a buffer bolt or an elastic element such as rubber, which is not limited here.

[0069] Please refer to Figure 3In an embodiment of this utility model, the opening and closing mechanism further includes a second limiting structure 710. The second limiting structure 710 is disposed on the mounting base 100 and located between the two transmission components 400. In the second position, the transmission component 400 abuts against the second limiting structure 710 to limit the rotation of the support component 200.

[0070] Specifically, since one end of each of the two transmission components 400 is rotatably connected to the mounting base 100 via the rotating component 500, and the other end extends in different directions, forming an angle between the two transmission components 400, the second limiting structure 710 includes a limiting post, which is vertically set on the mounting base 100 and located between the angle formed by the two transmission components 400. When it is necessary to pick up or put down the stator 10, the two holding components 200 need to be opened. At this time, the telescopic part of the drive component 300 retracts, and the two transmission components 400 rotate accordingly. The angle between the two transmission components 400 decreases, and they rotate in the direction of each other. When the two first connecting plates 410 abut against the limiting post, the two holding components 200 reach the second position, and the drive component 300 stops retracting. While ensuring that the stator 10 can be picked up or put down smoothly, the rotation stroke of the transmission components 400 and the holding components 200 is reduced, thereby improving processing efficiency.

[0071] In one embodiment, a second buffer is provided on each side of the limiting post for abutting against the first connecting plate 410 on both sides. The second buffer can be a buffer bolt or an elastic element such as rubber, and there is no limitation.

[0072] Please refer to Figure 1 and Figure 2 In an embodiment of this utility model, the opening and closing mechanism further includes a detection component 800, which is disposed on the mounting base 100 and is used to detect whether the buffer position carries a workpiece.

[0073] Specifically, the detection component 800 is mounted on the mounting base 100, which can be mounted on the support frame 600. The support frame 600 protrudes from the mounting base 100 and extends upward, giving the support frame 600 a certain height. This facilitates the detection component 800 in detecting whether the buffer position carries a workpiece. If a workpiece is detected, the drive component 300 drives the holding component 200 to rotate to the first position, covering the buffer position to form a processing position, waiting for the stator 10 to be wound. The setting of the detection component 800 can avoid ineffective work and improve winding efficiency.

[0074] The detection component 800 can use a photoelectric sensor to detect whether the buffer position carries a workpiece such as the stator 10 by emitting infrared light towards the buffer position. If the infrared light is reflected, it proves that the buffer position carries a workpiece. The detection component 800 can also use visual detection, etc., without limitation.

[0075] Please refer to Figure 1 In an embodiment of this utility model, the opening and closing mechanism further includes a support component 900, which is disposed on the mounting base 100. The support component 900 includes a rotation drive and a support component, and the buffer position is configured as the support component. The rotation drive is driven to connect with the support component to drive the support component to rotate.

[0076] Specifically, the rotation drive can be configured as a motor or a rotary cylinder. The rotation drive drives the carrier, i.e., the buffer position, to rotate, which in turn drives the stator 10 on the buffer position to rotate. Since the stator 10 includes multiple iron cores, when the two holding components 200 are in the first position and only one iron core is exposed at the processing position, the winding structure winds the exposed iron core. After the winding is completed, the rotation drive drives the stator 10 to rotate. The direction of rotation is not limited here. The stator 10 rotates until the adjacent iron core rotates to the processing position. At this time, the iron core is wound again. After the winding is completed, it rotates again. The above actions are repeated until all iron cores are wound. The drive component 300 drives the holding component 200 to rotate to the second position through the transmission component 400, so that the entire buffer position and the stator 10 on the buffer position are exposed for removal and placement of unwound workpieces. The whole action process is simple and smooth, improving the efficiency and quality of the stator 10 winding.

[0077] This utility model also proposes a stator winding machine, including the opening and closing mechanism described in any of the above embodiments. The specific structure of the opening and closing mechanism is as described in the above embodiments. Since this stator winding machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
