Description

Technical Field

[0001] This invention belongs to the field of industrial robot technology, and more specifically, relates to a flaring device. Background Technology

[0002] The flat wire stator is composed of multiple layers of conductors. When the conductors are initially inserted into the stator core, one end of each layer of conductors is in close contact with each other. In order to facilitate the subsequent twisting and welding process of the conductors, the multiple layers of conductors need to be separated. However, manual flaring or semi-automatic flaring equipment has poor flaring consistency and low work efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the purpose of this invention is to provide a flaring device.

[0005] To achieve the above objectives, the present invention proposes a flaring device for separating at least two layers of conductors in a multilayer conductor of a flat wire motor. The flat wire motor includes a stator, which includes a stator core and multiple layers of conductors wound on the stator core. The at least two layers of conductors include a first layer and a second layer. The flaring device includes: a mounting platform; a positioning device disposed on the mounting platform for fixing the stator core; and a wire splitting device disposed on the mounting platform, which includes a mounting frame and multiple wire splitters disposed on the mounting frame. The mounting frame is movable along the axial direction of the stator between a first position and a second position, and the wire splitters are movable along the radial direction of the stator between a third position and a fourth position. When the mounting frame is in the first position, the wire splitter moves to the third position to connect with the first layer of conductors, and the wire splitter moves from the third position to the fourth position to pull the first layer of conductors apart from the second layer of conductors.

[0006] The flaring device proposed in this application can be used to separate at least two layers of wire in a multi-layered conductor in a flat wire motor, thereby allowing the layers of wire to be separated from each other. The flat wire motor includes a stator, which comprises a stator core and multiple layers of wire wound around the stator core. The stator core has multiple wire holes arranged radially, through which the multiple layers of wire are respectively inserted, and wound radially around the stator core. In the initial state where the multiple layers of wire are wound around the stator core, the layers of wire are tightly adhered. To facilitate subsequent twisting and welding of the wires, it is necessary to separate the layers of wire to allow the operator to twist and weld them. Therefore, this application proposes a flaring device that can sequentially stretch any one layer of wire in the multi-layered conductor along the radial direction of the stator core, thereby separating the multiple layers of wire.

[0007] The flaring equipment includes a mounting platform, a positioning device, and a wire separating device. Both the positioning device and the wire separating device are mounted on the mounting platform. The positioning device is used to fix the stator core, while the wire separating device is used to stretch the multiple layers of conductors wound on the stator core. The wire separating device can stretch the multiple layers of conductors sequentially to separate them from each other, thus achieving the flaring effect of each layer of conductors in the stator.

[0008] Specifically, before flaring the multi-layer conductors in the stator using a flaring device, the stator is first placed in a positioning device. The positioning device can fix the stator core. Since the multi-layer conductors are wound around the stator core, when the stator core is fixed by the positioning device, the end of the multi-layer conductors connected to the stator core is also fixed.

[0009] Furthermore, the at least two layers of conductors separated in the multilayer conductor include a first layer and a second layer. After the stator core is fixed by the positioning device, the wire splitting device can move in directions toward and away from the stator core, and then the first layer of conductors is stretched by multiple wire splitters in the wire splitting device. Specifically, the wire splitting device includes a mounting frame and multiple wire splitters disposed on the mounting frame. The mounting frame can drive the multiple wire splitters to move between a first position and a second position along the axial direction of the stator, and the wire splitters can move between a third position and a fourth position along the radial direction of the stator.

[0010] The process of separating the first layer of conductors from the second layer of conductors by the splitter is as follows: With the stator core fixed by the positioning device, the mounting bracket in the splitter moves axially toward the stator core until it reaches the first position. At this time, multiple splitters move radially toward the stator core to the third position, with the number of splitters being greater than or equal to the number of conductors in the first layer. When a splitter is in the third position, it can connect to the corresponding conductor in the first layer. Then, the multiple splitters move radially toward the stator core in a direction away from the stator core to the fourth position. The splitters pull the first layer of conductors away from the stator core. Since one end of the first layer of conductors is wrapped around the stator core, the splitters can pull the end of the first layer of conductors away from the stator core, causing the first layer of conductors to bend. In this way, the first layer of conductors can be separated from the second layer of conductors.

[0011] In one possible technical solution, the first layer of conductors is located outside the second layer of conductors, and the splitting device can sequentially stretch the first layer of conductors and the second layer of conductors to different positions along the direction from the outside of the stator core to the axis of the stator core, so as to separate the first layer of conductors from the second layer of conductors.

[0012] By incorporating a positioning device within the flaring equipment, the stator core of the stator can be fixed, thereby securing one end of the multi-layered conductors wound around the stator core. This facilitates the stretching of the multi-layered conductors by the wire separating device. The wire separating device, configured as a mounting frame that can move along the stator's axial direction between a first and second position, and multiple wire separating units within the device that can move radially along the stator between a third and fourth position, allows the mounting frame to first move the multiple wire separating units to the first position. Then, the radial movement of the wire separating units stretches the first layer of conductors, separating them from the second layer, thus achieving the wire separating function of the flaring equipment for the multi-layered conductors in the stator. Compared to manual wire separating, the flaring equipment proposed in this application performs wire separating more efficiently. Furthermore, the distance between the multi-layered conductors after separation by the flaring equipment is controllable, resulting in higher separation accuracy and facilitating subsequent twisting and welding of the conductors in processing steps.

[0013] The flaring device according to the present invention may also have the following distinguishing technical features:

[0014] In the above technical solution, when the mounting bracket moves from the first position to the second position, the mounting bracket causes the splitter to separate from the first layer of conductors; when the mounting bracket moves from the second position to the first position, the splitter can also move radially along the stator to the fifth position to connect with the second layer of conductors and pull the second layer of conductors to move radially.

[0015] In this technical solution, the wire splitting device is further defined. After the wire splitter in the wire splitting device stretches the first layer of conductors to the fourth position, in order to separate the wire splitter from the first layer of conductors, the mounting frame drives multiple wire splitters to move in a direction away from the stator core. Specifically, the mounting frame moves from the first position along the axial direction of the stator in a direction away from the stator core until the mounting frame moves to the second position, at which point the wire splitter separates from the first layer of conductors.

[0016] Furthermore, the wire splitter can also stretch the second layer of conductors after stretching the first layer. Specifically, the mounting bracket moves from the second position along the axial direction of the stator towards the stator core until it reaches the first position. Then, the wire splitter moves radially along the stator to the fifth position, connecting with the second layer of conductors. Next, the wire splitter can move radially away from the stator core to the sixth position, at which point it stretches the end of the second layer of conductors away from the stator core to the sixth position, thus stretching the second layer of conductors. The sixth position is different from the fourth position.

[0017] By enabling the mounting bracket to move the splitter to the second position, the splitter can be separated from the first layer of conductors after the splitter has finished stretching the first layer of conductors. Then, the mounting bracket can move the splitter back to the first position, and then the splitter can be moved to different positions along the radial direction of the stator to stretch the second layer of conductors, thus realizing the stretching effect of the splitter on multiple layers of conductors.

[0018] In the above technical solution, any splitter further includes: a main body; a wire storage hole disposed at the end of the main body, wherein when the splitter is in the third and fourth positions, the wire storage hole is used to accommodate the first layer of wires, and when the splitter is in the fifth position, the wire storage hole is used to accommodate the second layer of wires.

[0019] In this technical solution, the structure of the splitter is defined. Specifically, each splitter includes a main body and a wire storage hole, wherein the wire storage hole is located at the end of the main body. When the splitter is in the third position, the wires in the first layer of conductors can be inserted into the wire storage hole of the corresponding splitter, thus connecting the first layer of conductors to the splitter. Then, the splitter moves radially along the stator to the fourth position. Since the first layer of conductors is located in the wire storage hole, the splitter can move the end of the first layer of conductors away from the stator core to the fourth position, thereby stretching the first layer of conductors and separating them from the second layer of conductors. Subsequently, when the mounting bracket moves the splitter in the direction away from the stator core to the second position, the wire storage holes in each splitter move relative to the first layer of conductors until each wire in the first layer of conductors separates from the corresponding wire storage hole, thus separating the first layer of conductors from the splitter.

[0020] Furthermore, after the splitter completes the stretching of the first layer of conductors, the splitter stretches the second layer of conductors. When the splitter moves to the fifth position, each conductor in the second layer of conductors is inserted into the corresponding wire storage hole of the splitter, thereby connecting the second layer of conductors to the splitter. In this way, the splitter can stretch the second layer of conductors.

[0021] By setting wire storage holes in the splitter, each wire in the multi-layer conductor can be inserted into the corresponding wire storage hole of the splitter, so that the splitter is connected to each layer of conductor. The splitter can stretch each layer of conductor, and the layers of conductor can be separated from each other.

[0022] In the above technical solution, any splitter further includes: a clearance hole, which is provided on the main body. The clearance hole and the wire storage hole are arranged sequentially along the extension direction of the main body. When the splitter is in the fifth position, the clearance hole is used to accommodate the first layer of wires.

[0023] In this technical solution, the structure of the splitter is further defined. When the splitter stretches the second layer of conductors, a clearance hole is provided on the main body to allow the stretched first layer of conductors to pass. Specifically, the wire storage hole and the clearance hole are arranged sequentially along the extension direction of the main body. When the splitter has completed stretching the first layer of conductors, the first layer of conductors is located outside the second layer of conductors. If no space is provided on the main body of the splitter to allow the first layer of conductors to pass, then when the second layer of conductors is inserted into the wire storage hole, the first layer of conductors located outside the second layer of conductors may easily interfere with the main body of the splitter. To avoid the above problem, a clearance hole is provided on the main body to allow the first layer of conductors to pass.

[0024] Specifically, when the splitter moves radially along the stator to the fifth position, the second layer of conductors can be inserted into the wire storage hole to connect with the splitter. Simultaneously, the stretched first layer of conductors, located outside the second layer, is inserted into the clearance hole, thus preventing interference between the first layer and the main body. The splitter moves radially along the stator from the fifth position to the sixth position to complete the stretching of the second layer of conductors.

[0025] Furthermore, to avoid interference between the first layer of conductors and the wall of the clearance hole when the splitter pulls the second layer of conductors, the length of the clearance hole is set to be greater than the distance between the fifth and sixth positions. Thus, even if the splitter moves radially along the stator, the first layer of conductors located within the clearance hole will not come into contact with the hole wall, and the splitter will not perform secondary stretching on the first layer of conductors.

[0026] By setting clearance holes on the main body of the splitter, the first layer of wires can be avoided when the splitter stretches the second layer of wires, thus preventing interference between the first layer of wires and the splitter.

[0027] In the above technical solution, the flaring device further includes: a first driving unit connected to the splitter, the first driving unit being used to drive the splitter to move radially; and a second driving unit connected to the splitter, the second driving unit being used to drive the mounting bracket to move axially.

[0028] In this technical solution, in order to enable multiple splitters to move radially along the stator, a first driving unit connected to the multiple splitters is also provided in the flaring device. The first driving unit can drive the multiple splitters to move between multiple positions radially along the stator.

[0029] Furthermore, in order to enable the mounting bracket to move along the stator axis, the flaring device is also provided with a second drive unit connected to the splitter device. The second drive unit is used to drive the mounting bracket to move along the stator axis between the first position and the second position.

[0030] By setting a first drive unit and a second drive unit in the flaring device, the second drive unit can drive the mounting bracket to move multiple splitters between the first and second positions along the axial direction of the stator. The first drive unit can also drive multiple splitters to move between multiple positions along the radial direction of the stator, thereby achieving the separation of multiple layers of conductors from each other through multiple splitters.

[0031] In the above technical solution, the first driving unit further includes: multiple rollers, each roller corresponding to a multiple distributor, with the first end of any roller connected to the corresponding distributor; and a driving disk, including multiple driving grooves, each driving groove corresponding to a multiple roller, with the second end of any roller located in the corresponding driving groove, the roller abutting against the groove wall of the driving groove, and the groove wall of the driving groove being able to push the roller to move radially along the driving disk, thereby driving the distributor to move radially along the driving disk.

[0032] In this technical solution, the structure of the first driving unit is defined. The first driving unit includes multiple rollers that can move radially along the stator. The number of rollers is the same as the number of distributors, and the multiple rollers are arranged in a one-to-one correspondence with the multiple distributors. The first end of the roller is connected to the distributor, so that the movement of the roller can drive the distributor to move radially along the stator.

[0033] Furthermore, to enable the rollers to move radially along the stator, a drive disc for driving the rollers is also provided in the first drive unit. With the stator core fixed by the positioning device, the drive disc is coaxial with the stator core. Specifically, the drive disc has multiple drive slots, the number of which is the same as the number of rollers, and each drive slot corresponds to one roller. The second end of the roller is located within the corresponding drive slot, and the wall of the second end of the roller abuts against the wall of the drive slot. The drive disc can rotate within a certain angle range. When the drive disc rotates, it drives each drive slot to rotate around the axis of the drive disc within a certain angle range. Since the first end of the roller is connected to the distributor, the roller does not rotate around the axis of the drive disc with its rotation. When the drive disc rotates to different angles, the position where the drive slot abuts against the roller changes. The drive groove is a groove-shaped structure with a variable cross section. When the position of the drive groove abutting the roller changes, the drive groove can push the roller to move between different positions along the radial direction of the stator, thereby causing the roller to push the corresponding distributor to move between different positions along the radial direction of the stator.

[0034] In one possible technical solution, the first drive unit also includes an angle detector, which is movably connected to the drive disk, allowing the drive disk to rotate relative to the angle detector. The angle detector measures the rotation angle of the drive disk. Understandably, the position moved by the splitter is related to the position moved by the roller, and the position moved by the roller is related to the angle rotated by the drive disk. The preset position to which the splitter is to move corresponds to the preset angle rotated by the drive disk. The angle detector can detect whether the angle rotated by the drive disk is the preset angle, thus determining whether the splitter can move to the preset position based on the angle rotated by the drive disk. This facilitates operator adjustments and improves the movement accuracy of the splitter.

[0035] By setting a drive disk and a roller in the drive groove of the drive disk in the first drive unit, and connecting the roller to the splitter, the splitter can be driven to move between different positions along the radial direction of the stator by the rotation of the drive disk, thereby realizing the function of splitting multiple layers of wires.

[0036] In the above technical solution, the groove wall of the drive groove is curved, and the drive disk can rotate within a first angle range. As the drive disk rotates, the groove wall of the drive groove pushes the roller to move radially along the drive disk.

[0037] In this technical solution, the shape of the drive groove is defined. Specifically, the groove wall is curved, meaning the drive groove is constructed as a variable cross-section structure. The drive disk can rotate within a first angular range, and the drive groove can rotate around the axis of the drive disk as the drive disk rotates. Since the first end of the roller is connected to the distributor, the roller does not rotate around the axis of the drive disk as the drive groove rotates. As the drive groove rotates, the second end of the roller abuts against different positions of the groove wall. Because the drive groove is curved, it allows the drive groove to push the roller to multiple positions along the radial direction of the stator, thereby enabling the roller to drive the distributor to move between multiple positions along the radial direction of the stator.

[0038] Understandably, the position to which the splitter moves is related to the position to which the roller moves, and the position to which the roller moves is related to the angle of rotation of the drive slot. By controlling the drive disc to drive the drive slot to rotate within a first angle range, the splitter can move between multiple positions along the radial direction of the stator, thereby enabling the splitter to stretch the multi-layer conductors and thus separate the multi-layer conductors from each other.

[0039] In one possible technical solution, the drive groove is constructed to be waist-shaped.

[0040] By setting the wall of the drive groove to a curved surface, the rotation of the drive groove around the axis of the drive disc can drive the roller to move between multiple positions along the radial direction of the stator. In turn, the roller drives the corresponding splitter to move between equal positions along the radial direction of the stator, thereby stretching the multi-layer conductors and separating the multi-layer conductors from each other.

[0041] In the above technical solution, the first driving part further includes: a driving rod connected to the driving disk; and a driving member connected to the driving rod, which can push the driving rod to move so as to drive the driving disk to rotate.

[0042] In this technical solution, the structure of the first driving unit is defined. The first driving unit includes a driving rod and a driving component, wherein the driving rod is connected to the driving disk, the driving component is connected to the driving rod, and the driving component is disposed on the mounting bracket. Specifically, the driving component can push the driving rod to move through telescopic movement, thereby enabling the driving rod to drive the driving disk to rotate within a first angle range, thereby realizing the movement of the distributor between multiple positions along the radial direction of the stator.

[0043] In one possible technical solution, the driving component is a retractable electric cylinder.

[0044] By setting a drive rod and a drive component in the first drive unit, and connecting the two ends of the drive rod to the drive disk and the drive component respectively, the drive component can drive the drive disk to rotate within a first angle range through the drive rod, thereby enabling the distributor to move between multiple positions along the radial direction of the stator.

[0045] In the above technical solution, the splitter device further includes: a support plate located between multiple splitters and the mounting frame, the support plate being used to support multiple splitters; multiple support blocks located between the mounting frame and the support plate, multiple support frames being used to support the support plate, the multiple support blocks, the mounting frame and the support plate forming a receiving cavity, and a drive plate located inside the receiving cavity.

[0046] In this technical solution, to ensure the stability of the splitter, a support plate is also provided in the splitter device to support multiple splitters. Specifically, the support plate is located between the mounting bracket and the multiple splitters, and the support plate supports the multiple splitters to ensure their stability. Further, the support plate is located between the drive plate and the multiple splitters, and to allow the multiple rollers to pass through, multiple through holes are provided on the support plate to allow the rollers to pass through and connect to the splitter. The multiple through holes correspond one-to-one with the multiple rollers.

[0047] Furthermore, the distribution device also includes multiple support blocks positioned between the mounting frame and the support plate, providing support for the support plate. These support blocks, along with the mounting frame and support plate, form a receiving cavity, within which the drive plate is located. Further, to ensure smooth rotation of the drive plate, a slewing bearing is provided between the drive plate and the mounting frame. The drive plate rests on the slewing bearing, which in turn rests on the mounting frame. During drive plate rotation, the slewing bearing eliminates friction between the drive plate and the mounting frame, allowing for smooth rotation of the drive plate.

[0048] By installing support plates below multiple splitters, the splitters can be supported to maintain stability. Multiple support blocks are installed between the support plates and the mounting frame to support the support plates, and the support blocks, support plates, and mounting frame together form a cavity to accommodate the drive plate and slewing bearing. This avoids the drive plate occupying additional installation space and facilitates the miniaturization design of the flaring equipment.

[0049] In the above technical solution, the flaring device further includes: multiple brackets disposed on the mounting platform; a positioning device including a positioning plate, the positioning plate having a stator cavity for accommodating the stator, the positioning plate being connected to the end of the bracket away from the mounting platform; and a splitting device movably connected to at least one of the multiple brackets, the splitting device being able to move to a first position in the direction toward the positioning plate, or to a second position in the direction away from the positioning plate.

[0050] In this technical solution, multiple supports are provided on the mounting platform, and a positioning plate is provided in the positioning device. The positioning plate has a stator cavity for accommodating the stator. The positioning plate is connected to the end of the supports opposite to the mounting platform, and the supports fix the positioning plate. When the positioning device fixes the stator core, the stator core is located inside the stator cavity, and a certain distance is left between the stator core and the mounting platform, so that the branching device can be set between the fixed stator core and the mounting platform.

[0051] Furthermore, in order to enable the wire distribution device to move along the axial direction of the stator core between a first position and a second position, either towards or away from the stator core, this application movably connects the wire distribution device to at least one of a plurality of supports, allowing the wire distribution device to reciprocate along the extension direction of the support. In this way, the support can both fix the wire distribution device and guide it.

[0052] In one possible technical solution, there are two brackets, which are respectively set on both sides of the splitter device. The splitter device is movably connected to one of the brackets, and the two ends of the positioning plate are fixedly connected to the two brackets respectively.

[0053] By setting multiple brackets on the mounting platform and movably connecting the splitter device to at least one of the brackets, the splitter device can be fixed by the brackets on the one hand, and guided by the brackets on the other hand, so that the splitter device can move back and forth between the first and second positions along the brackets.

[0054] In the above technical solution, the flaring device further includes: a guide rail, which is mounted on at least one of the multiple brackets; a walking device, which is mounted on the mounting frame and is adapted to the guide rail; and a second drive unit, which is mounted on the mounting platform and is electrically connected to the walking device, and is used to drive the walking device to move along the guide rail.

[0055] In this technical solution, in order for the splitter to reciprocate between the first and second positions along the bracket, a component for enabling the splitter to move needs to be provided on the bracket to which the splitter is connected. Specifically, at least one of the brackets is also provided with a guide rail, and a traveling device adapted to the guide rail is provided on the mounting frame of the splitter. The traveling device is movably connected to the guide rail and can drive the mounting frame to reciprocate between the first and second positions along the guide rail under external force.

[0056] Furthermore, the second drive unit is connected to the traveling device, which can drive the traveling device to move along the guide rail, thereby enabling the traveling device to move the mounting frame between the first position and the second position, thereby realizing the movement of multiple splitters along the stator axis, so that the splitters can stretch the multi-layer conductors in sequence to separate the multi-layer conductors from each other.

[0057] Furthermore, the second drive unit is mounted on the mounting platform. In one possible technical solution, the second drive unit is an electric cylinder.

[0058] By installing a guide rail on at least one of the multiple supports and a traveling device adapted to the guide rail on the mounting frame, the traveling device can be driven to move along the guide rail by a second drive unit. The traveling device can drive the mounting frame to reciprocate between a first position and a second position, thereby realizing the movement of multiple splitters along the stator axis. This allows the splitters to stretch multiple layers of conductors sequentially, thus separating the conductors. Furthermore, the connection between the traveling device and the guide rail also allows the splitter assembly to be fixed in place.

[0059] In the above technical solution, the positioning device further includes: multiple guide members, which are located on the side of the positioning plate away from the mounting platform, and each guide member is provided with a guide groove, the groove opening of which faces the stator cavity.

[0060] In this technical solution, to facilitate the placement of the stator core into the stator cavity of the mounting plate, multiple guide members are provided in the positioning device. These guide members guide the stator core so that it can be accurately inserted into the stator cavity. The guide members are located on the side of the positioning plate away from the mounting platform. During the insertion of the stator into the stator cavity from this side of the positioning plate, the guide members first guide the stator to ensure accurate insertion.

[0061] Furthermore, each guide member is provided with a guide groove, the opening of which is located at the edge of the stator cavity and faces the stator cavity. The guide grooves of multiple guide members enclose a nearly circular area, thereby guiding the stator during the process of inserting it into the stator cavity, so that the stator can be accurately inserted into the stator cavity.

[0062] By setting multiple guides on the side of the positioning plate away from the mounting platform, the stator can be guided by the multiple guides, so that the stator can be accurately inserted into the stator cavity.

[0063] In the above technical solution, the stator further includes a rotor cavity, and the positioning device further includes: a positioning column; a plurality of tensioning blocks, any one of which is movably connected to the positioning column. When the stator is located in the stator cavity, the plurality of tensioning blocks can move radially away from the positioning column to abut against the wall of the rotor cavity.

[0064] In this technical solution, the structure of the positioning device is further defined. The stator to be fixed by the positioning device includes a rotor cavity, and the positioning device can fix the stator core by pressing against the wall of the rotor cavity. Specifically, the positioning device also includes a positioning post and multiple tensioning blocks. The multiple tensioning blocks are circumferentially disposed on the positioning post, and the tensioning blocks can move radially relative to the positioning post. After the stator core moves into position in the stator cavity, the multiple tensioning blocks are located in the rotor cavity. The multiple tensioning blocks move radially towards the wall of the rotor cavity until the tensioning blocks abut against the wall of the rotor cavity. Then, the tensioning blocks continue to move, thereby pressing the inner wall of the rotor cavity with the multiple tensioning blocks to fix the stator core.

[0065] Furthermore, when it is necessary to remove the stator from the positioning device, multiple tension blocks can move radially toward the positioning post along the stator core to separate the multiple tension blocks from the stator core, allowing the stator to be removed from the positioning device.

[0066] In one possible technical solution, the number of tensioning blocks is three, and the three tensioning blocks are evenly distributed along the circumference of the positioning column.

[0067] By setting positioning posts and multiple tensioning blocks in the positioning device, the stator core can be fixed by pressing the wall of the rotor cavity in the stator core through the multiple tensioning blocks.

[0068] In the above technical solution, the positioning device further includes a third driving unit connected to a plurality of tensioning blocks, the third driving unit being used to drive the tensioning blocks to move radially.

[0069] In this technical solution, to enable the multiple tensioning blocks to move radially along the stator, a third driving unit connected to the multiple tensioning blocks is provided in the positioning device. The third driving unit is located on the positioning post and can drive the multiple tensioning blocks to move in a direction toward or away from the positioning post. When the stator moves into the stator cavity, the third driving unit drives the tensioning blocks to move in a direction away from the positioning post, so that the multiple tensioning blocks can abut against the wall of the rotor cavity. The stator core is fixed by the compression of the rotor cavity by the multiple tensioning blocks. When the stator needs to be removed from the stator cavity, the third driving unit drives the multiple tensioning blocks to move in a direction toward the positioning post, and the multiple tensioning blocks separate from the stator core, thereby allowing the stator to be removed from the stator cavity.

[0070] By setting a third drive unit connected to multiple tension blocks in the positioning device, the third drive unit can drive the multiple tension blocks to move in a direction toward or away from the positioning column, so that the tension blocks can squeeze the inner wall of the rotor cavity and fix the stator core.

[0071] In the above technical solution, the flaring device further includes: a protective plate, which is located on the side of the positioning plate facing the mounting platform. The inner edge of the protective plate protrudes from the cavity wall of the stator cavity. The inner edge of the protective plate is provided with multiple slits for the wires to pass through.

[0072] In this technical solution, since slot paper is usually installed in the slots of the stator core, in order to avoid damage to the slot paper during the pulling of the multi-layer conductors by the wire separating device, a protective disc is also set in the flaring device to protect the slot paper.

[0073] Specifically, the protective disc is located on the side of the positioning plate facing the mounting platform. The protective disc is constructed as a ring structure, with its inner edge protruding from the cavity wall of the stator cavity. When the stator core is located inside the stator cavity, the inner edge of the protective disc protrudes from the cavity wall, thus shielding the slot paper in the tooth grooves and protecting the slot paper.

[0074] Furthermore, to allow the conductors of each layer to pass through the protective disc so that the conductor distribution device can stretch the conductors, multiple slits for the conductors to pass through are provided on the inner edge of the protective disc. When the stator core is located inside the stator cavity, the conductors of each layer can pass through the protective disc through the slits. This serves two purposes: firstly, the protective disc protects the slotted paper, and secondly, it prevents interference between the conductors and the protective disc.

[0075] In the above technical solution, the flaring device further includes: a fourth drive unit, which is located on the positioning plate and connected to the protective disc. The fourth drive unit is used to drive the protective disc to rotate within a second angle range.

[0076] In this technical solution, the flaring device also includes a fourth drive unit for adjusting the rotation angle of the protective disc. Understandably, if the slits on the protective disc cannot be aligned with the wire, the wire cannot pass smoothly through the protective disc. To ensure that the multiple slits on the protective disc are aligned with the wire, the flaring device also includes a fourth drive unit for driving the protective disc to rotate. This fourth drive unit can drive the protective disc to rotate within a second angle range, thus adjusting the protective disc to a suitable position so that each slit can be aligned with the wire, allowing the wire to pass smoothly through the slits, facilitating the stretching of each layer of wire by the wire separating device.

[0077] In the above technical solution, the flaring device further includes: a limiting block connected to the protective plate; and multiple stop members connected to the positioning plate. The multiple stop members are located on both sides of the limiting block, and when the protective plate drives the limiting block to rotate, the stop members can abut against the limiting block.

[0078] In this technical solution, to limit the angular range of rotation of the protective disc, a limiting block and multiple stops are also provided in the flaring device for circumferentially limiting the limiting disc. The limiting block is connected to the protective disc, and the multiple stops are connected to the positioning plate, with the stops located on both sides of the limiting block. Specifically, when the fourth drive unit drives the protective disc to rotate, the protective disc drives the limiting block to rotate together. When the limiting block abuts against a stop located on one side of the limiting block, the limiting block cannot move further, thus preventing the protective disc from moving further. In this way, the multiple stops limit the protective disc, allowing it to rotate within a second angular range.

[0079] In one possible technical solution, the stop component includes a mounting component and screws. The mounting component is fixedly connected to the positioning plate, and it has threaded holes. The screws are connected to the mounting component through the threaded holes. The position of the screws is adjustable; the angle range of the second angle can be adjusted by adjusting the distance between the screws located on both sides of the limiting block.

Detailed Implementation

[0099] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0100] 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 therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0101] The following reference Figures 1 to 15 A flaring device 100 according to some embodiments of the present invention is described.

[0102] Example 1:

[0103] like Figure 1 , Figure 2 and Figure 4As shown, the present invention proposes a flaring device 100 for separating at least two layers of conductors in a multilayer conductor of a flat wire motor. The flat wire motor includes a stator, which includes a stator core and multiple layers of conductors wound on the stator core. The at least two layers of conductors include a first layer of conductors and a second layer of conductors. The flaring device 100 includes: a mounting platform 110; a positioning device 120 disposed on the mounting platform 110 for fixing the stator core; and a wire splitting device 130 disposed on the mounting platform 110. The wire splitting device 130 includes a mounting frame 131 and a plurality of wire splitters 140 disposed on the mounting frame 131. The mounting frame 131 is movable along the axial direction of the stator between a first position and a second position, and the wire splitters 140 are movable along the radial direction of the stator between a third position and a fourth position. When the mounting frame 131 is in the first position, the wire splitter 140 moves to the third position to connect with the first layer of conductors, and the wire splitter 140 moves from the third position to the fourth position to pull the first layer of conductors apart from the second layer of conductors.

[0104] The flaring device 100 proposed in this application can be used to separate at least two layers of wire in a multi-layer conductor in a flat wire motor, thereby enabling the layers of wire to be separated from each other. The flat wire motor includes a stator, which comprises a stator core and multiple layers of wire wound around the stator core. The stator core has multiple wire holes arranged radially, through which the multiple layers of wire are respectively inserted, and wound radially around the stator core. In the initial state where the multiple layers of wire are wound around the stator core, the layers of wire are tightly adhered. To facilitate subsequent twisting and welding of the wires, it is necessary to separate the layers of wire to allow the operator to twist and weld them. Therefore, this application proposes a flaring device 100 that can sequentially stretch any one layer of wire in the multi-layer conductor along the radial direction of the stator core to separate the multiple layers of wire.

[0105] The flaring device 100 includes a mounting platform 110, a positioning device 120, and a wire separating device 130. Both the positioning device 120 and the wire separating device 130 are mounted on the mounting platform 110. The positioning device 120 is used to fix the stator core, and the wire separating device 130 is used to stretch the multiple layers of conductors wound on the stator core. The wire separating device 130 can stretch the multiple layers of conductors sequentially to separate them from each other, thus achieving the flaring effect of each layer of conductors in the stator.

[0106] Specifically, before the multi-layer conductors in the stator are flared by the flaring device 100, the stator is first placed in the positioning device 120. The positioning device 120 can fix the stator core. Since the multi-layer conductors are wound on the stator core, when the stator core is fixed by the positioning device 120, the end of the multi-layer conductors connected to the stator core is also fixed.

[0107] Furthermore, the at least two layers of conductors separated in the multilayer conductor include a first layer of conductors and a second layer of conductors. After the stator core is fixed by the positioning device 120, the wire splitting device 130 can move in directions toward and away from the stator core, and then the first layer of conductors is stretched by a plurality of wire splitters 140 in the wire splitting device 130. Specifically, the wire splitting device 130 includes a mounting frame 131 and a plurality of wire splitters 140 disposed on the mounting frame 131. The mounting frame 131 can drive the plurality of wire splitters 140 to move along the axial direction of the stator between a first position and a second position, and the wire splitters 140 can move along the radial direction of the stator between a third position and a fourth position.

[0108] The process by which the splitter device 130 separates the first layer of conductors from the second layer of conductors is as follows: With the stator core fixed by the positioning device 120, the mounting bracket 131 in the splitter device 130 moves axially toward the stator core until it reaches the first position. At this time, multiple splitters 140 move radially toward the stator core to the third position. The number of splitters 140 is greater than or equal to the number of conductors in the first layer of conductors. When a splitter 140 is in the third position, it can connect to the corresponding conductor in the first layer of conductors. Then, the multiple splitters 140 move radially toward the stator core to the fourth position, pulling the first layer of conductors away from the stator core. Since one end of the first layer of conductors is wrapped around the stator core, the splitter 140 can pull the end of the first layer of conductors away from the stator core, causing the first layer of conductors to bend. In this way, the first layer of conductors can be separated from the second layer of conductors.

[0109] In one possible embodiment, the first layer of conductors is located outside the second layer of conductors, and the splitting device 130 can sequentially stretch the first layer of conductors and the second layer of conductors to different positions along a direction from the outside of the stator core to the axis of the stator core, so as to separate the first layer of conductors from the second layer of conductors. Figure 10 , Figure 11 and Figure 12 As shown, the multiple layers of conductors in the stator are tightly attached to each other when they are not separated, such as... Figure 13 , Figure 14 and Figure 15 As shown, after the wire separating device 130 separates the multiple layers of conductors in the stator, there is a certain distance between each layer of conductors.

[0110] By providing a positioning device 120 in the flaring device 100, the stator core of the stator can be fixed, thereby fixing one end of the multi-layer conductors wound on the stator core, facilitating the stretching of the multi-layer conductors by the wire splitting device 130. By providing a wire splitting device 130 in the flaring device 100, and configuring the wire splitting device 130 as a mounting frame 131 that can move along the axial direction of the stator between a first and a second position, and configuring the multiple wire splitters 140 in the wire splitting device 130 to move along the radial direction of the stator between a third and a fourth position, the multiple wire splitters 140 can first be moved to the first position by the mounting frame 131, and then the first layer of conductors can be stretched by the radial movement of the wire splitters 140, so that the first layer of conductors is separated from the second layer of conductors, thus realizing the wire splitting function of the multi-layer conductors in the stator by the flaring device 100. Compared to manual wire splitting, the flaring device 100 proposed in this application can perform wire splitting more efficiently. Furthermore, the distance between the multi-layer conductors after splitting by the flaring device 100 is controllable, and the wire splitting accuracy is higher, which makes it easier to twist and weld the conductors in subsequent processing steps.

[0111] Example 2:

[0112] like Figure 4 , Figure 5 and Figure 6 As shown, in a specific embodiment based on Embodiment 1, when the mounting bracket 131 moves from the first position to the second position, the mounting bracket 131 causes the splitter 140 to separate from the first layer of conductors; when the mounting bracket 131 moves from the second position to the first position, the splitter 140 can also move radially along the stator to the fifth position to connect with the second layer of conductors and pull the second layer of conductors to move radially.

[0113] In this embodiment, the wire splitting device 130 is further defined. After the wire splitter 140 in the wire splitting device 130 stretches the first layer of conductors to the fourth position, in order to separate the wire splitter 140 from the first layer of conductors, the mounting frame 131 drives multiple wire splitters 140 to move in a direction away from the stator core. Specifically, the mounting frame 131 moves from the first position along the axial direction of the stator in a direction away from the stator core until the mounting frame 131 moves to the second position, at which point the wire splitter 140 separates from the first layer of conductors.

[0114] Furthermore, the wire splitter 130 can also stretch the second layer of conductors after stretching the first layer. Specifically, the mounting bracket 131 moves from the second position along the axial direction of the stator towards the stator core until it moves to the first position. Then, the wire splitter 140 moves radially along the stator to the fifth position, where it connects to the second layer of conductors. Next, the wire splitter 140 can move radially away from the stator core to the sixth position, where it stretches the end of the second layer of conductors away from the stator core to achieve the stretching of the second layer. The sixth position is different from the fourth position.

[0115] By enabling the mounting bracket 131 to move the splitter 140 to the second position, the splitter 140 can be separated from the first layer of conductors after the splitter 130 has finished stretching the first layer of conductors. Then, the mounting bracket 131 can move the splitter 140 back to the first position, and then the splitter 140 can be moved to different positions along the radial direction of the stator to stretch the second layer of conductors, thus realizing the stretching effect of the splitter 130 on the multi-layer conductors.

[0116] Example 3:

[0117] like Figure 3 As shown, in a specific embodiment based on any of the above embodiments, any splitter 140 includes: a main body 141; and a wire storage hole 142 disposed at the end of the main body 141. When the splitter 140 is in the third and fourth positions, the wire storage hole 142 is used to accommodate the first layer of wires, and when the splitter 140 is in the fifth position, the wire storage hole 142 is used to accommodate the second layer of wires.

[0118] In this embodiment, the structure of the splitter 140 is defined. Specifically, any splitter 140 includes a main body 141 and a wire storage hole 142, wherein the wire storage hole 142 is located at the end of the main body 141. When the splitter 140 is in the third position, the wires in the first layer of conductors can be inserted into the wire storage hole 142 of the corresponding splitter 140, thus connecting the first layer of conductors to the splitter 140. Then, the splitter 140 moves radially along the stator to the fourth position. Since the first layer of conductors is located in the wire storage hole 142, the splitter 140 can move the end of the first layer of conductors away from the stator core to the fourth position, thereby completing the stretching of the first layer of conductors and separating the first layer of conductors from the second layer of conductors. Subsequently, when the mounting bracket 131 drives the splitter 140 to move to the second position in the direction away from the stator core, the wire storage hole 142 in each splitter 140 moves relative to the first layer of wires until each wire in the first layer of wires separates from the corresponding wire storage hole 142, thus separating the first layer of wires from the splitter 140.

[0119] Furthermore, after the splitter 130 completes the stretching of the first layer of conductors, the splitter 130 stretches the second layer of conductors. When the splitter 140 moves to the fifth position, each conductor in the second layer of conductors is inserted into the corresponding wire storage hole 142 of the splitter 140, thereby connecting the second layer of conductors to the splitter 140. In this way, the splitter 140 can stretch the second layer of conductors.

[0120] By providing wire storage holes 142 in the splitter 140, each wire in the multi-layer wire can be inserted into the corresponding wire storage hole 142 of the splitter 140, so that the splitter 140 is connected to each layer of wire, and the splitter 140 can stretch each layer of wire, and the layers of wire can be separated from each other.

[0121] like Figure 3 As shown, any splitter 140 further includes: a clearance hole 143, which is provided on the main body 141. The clearance hole 143 and the wire storage hole 142 are arranged sequentially along the extension direction of the main body 141. When the splitter 140 is in the fifth position, the clearance hole 143 is used to accommodate the first layer of wires.

[0122] In this embodiment, the structure of the splitter 140 is further defined. When the splitter 140 stretches the second layer of conductors, a clearance hole 143 is provided on the main body 141 to avoid the stretched first layer of conductors. Specifically, along the extension direction of the main body 141, the wire storage hole 142 and the clearance hole 143 are arranged sequentially. When the splitter 130 has completed stretching the first layer of conductors, the first layer of conductors is located outside the second layer of conductors. If no space for avoiding the first layer of conductors is provided on the main body 141 of the splitter 140, then when the second layer of conductors is inserted into the wire storage hole 142, the first layer of conductors located outside the second layer of conductors is prone to interference with the main body 141 of the splitter 140. To avoid the above problem, a clearance hole 143 for avoiding the first layer of conductors is provided on the main body 141.

[0123] Specifically, when the splitter 140 moves radially along the stator to the fifth position, the second layer of conductors can be inserted into the wire storage hole 142 to connect with the splitter 140. Simultaneously, the stretched first layer of conductors, located outside the second layer, is inserted into the clearance hole 143, thereby preventing interference between the first layer and the main body 141. The splitter 140 moves radially along the stator from the fifth position to the sixth position to complete the stretching of the second layer of conductors.

[0124] Furthermore, to avoid interference between the first layer of conductors and the wall of the clearance hole 143 when the splitter 140 pulls the second layer of conductors, the length of the clearance hole 143 is set to be greater than the distance between the fifth and sixth positions. Thus, even if the splitter 140 moves radially along the stator, the first layer of conductors located within the clearance hole 143 will not come into contact with the wall of the clearance hole 143, and the splitter 140 will not perform secondary stretching on the first layer of conductors.

[0125] By providing a clearance hole 143 on the main body 141 of the splitter 140, the first layer of wires that have been stretched can be avoided when the splitter 140 stretches the second layer of wires, thus preventing interference between the first layer of wires and the splitter 140.

[0126] Example 4:

[0127] like Figure 4 and Figure 5 As shown, in a specific embodiment based on any of the above embodiments, the flaring device further includes: a first driving unit 150 connected to the splitter 130, the first driving unit 150 being used to drive the splitter 140 to move radially; and a second driving unit 111 connected to the splitter 130, the second driving unit 111 being used to drive the mounting bracket 131 to move axially.

[0128] In this embodiment, in order to enable the multiple splitters 140 to move radially along the stator, the flaring device is further provided with a first driving unit 150 connected to the multiple splitters 140. The first driving unit 150 can drive the multiple splitters 140 to move between multiple positions radially along the stator.

[0129] Furthermore, in order to enable the mounting bracket 131 to move along the stator axis, a second drive unit 111 connected to the branching device 130 is provided in the flaring device. The second drive unit 111 is used to drive the mounting bracket 131 to move along the stator axis between the first position and the second position.

[0130] By providing a first drive unit 150 and a second drive unit 111 in the flaring device, the second drive unit 111 can drive the mounting bracket 131 to move multiple splitters 140 along the axial direction of the stator between a first position and a second position. The first drive unit 150 can also drive multiple splitters 140 along the radial direction of the stator between multiple positions, thereby achieving the separation of multiple layers of conductors from each other through multiple splitters 140.

[0131] Example 5:

[0132] like Figure 6As shown, in a specific embodiment based on any of the above embodiments, the first driving unit 150 includes: a plurality of rollers 151, each roller 151 being configured in a one-to-one correspondence with a plurality of splitters 140, with the first end of any roller 151 connected to the corresponding splitter 140; and a driving disk 152, including a plurality of driving grooves 153, each driving groove 153 being configured in a one-to-one correspondence with a plurality of rollers 151, with the second end of any roller 151 located within the corresponding driving groove 153, the roller 151 abutting against the groove wall of the driving groove 153, and the groove wall of the driving groove 153 being able to push the roller 151 to move radially along the driving disk 152, thereby driving the splitter 140 to move radially along the driving disk 152.

[0133] In this embodiment, the structure of the first drive unit 150 is defined. The first drive unit 150 includes a plurality of rollers 151 that can move radially along the stator. The number of rollers 151 is the same as the number of distributors 140, and the plurality of rollers 151 are arranged in a one-to-one correspondence with the plurality of distributors 140. The first end of the roller 151 is connected to the distributor 140, so that the movement of the roller 151 can drive the distributor 140 to move radially along the stator.

[0134] Furthermore, to enable the rollers 151 to move radially along the stator, a drive disk 152 for driving the rollers 151 is also provided in the first drive unit 150. With the stator core fixed by the positioning device 120, the drive disk 152 is coaxial with the stator core. Specifically, the drive disk 152 has multiple drive grooves 153, the number of which is the same as the number of rollers 151, and each drive groove 153 corresponds to one roller 151. The second end of each roller 151 is located within a corresponding drive groove 153, and the wall of the second end of the roller 151 abuts against the groove wall of the drive groove 153. The drive disk 152 can rotate within a certain angle range. When the drive disk 152 rotates, it can drive each drive groove 153 to rotate around the axis of the drive disk 152 within a certain angle range. Since the first end of roller 151 is connected to distributor 140, roller 151 does not rotate around the axis of drive disk 152 as drive disk 152 rotates. When drive disk 152 rotates to different angles, the position where drive groove 153 abuts against roller 151 changes. Drive groove 153 is a groove-shaped structure with a variable cross-section. When the position where drive groove 153 abuts against roller 151 changes, drive groove 153 can push roller 151 to move between different positions along the radial direction of stator, thereby causing roller 151 to push the corresponding distributor 140 to move between different positions along the radial direction of stator.

[0135] In one possible embodiment, the first drive unit 150 is further provided with an angle detector, which is movably connected to the drive disk 152, and the drive disk 152 can rotate relative to the angle detector. The angle detector can measure the rotation angle of the drive disk 152. Understandably, the position moved by the splitter 140 is related to the position moved by the roller 151, and the position moved by the roller 151 is related to the angle rotated by the drive disk 152. The preset position to which the splitter 140 is to move corresponds to the preset angle rotated by the drive disk 152. The angle detector can detect whether the angle rotated by the drive disk 152 is the preset angle, thereby determining whether the splitter 140 can move to the preset position based on the angle rotated by the drive disk 152. This facilitates operator adjustments and improves the movement accuracy of the splitter 140.

[0136] By providing a drive disk 152 and a roller 151 in the drive groove 153 of the drive disk 152 in the first drive unit 150, and connecting the roller 151 to the splitter 140, the splitter 140 can be driven to move between different positions along the radial direction of the stator by the rotation of the drive disk 152, thereby realizing the function of splitting multiple layers of wires by the splitter 140.

[0137] Furthermore, the groove wall of the drive groove 153 is curved, and the drive disk 152 can rotate within a first angle range. As the drive disk 152 rotates, the groove wall of the drive groove 153 pushes the roller 151 to move radially along the drive disk 152.

[0138] In this embodiment, the shape of the drive groove 153 is defined. Specifically, the groove wall of the drive groove 153 is curved, that is, the drive groove 153 is constructed as a variable cross-section structure. The drive disk 152 can rotate within a first angle range, and the drive groove 153 can rotate around the axis of the drive disk 152 as the drive disk 152 rotates. Since the first end of the roller 151 is connected to the distributor 140, the roller 151 does not rotate around the axis of the drive disk 152 as the drive groove 153 rotates. As the drive groove 153 rotates, the second end of the roller 151 abuts against different positions of the groove wall of the drive groove 153. Since the drive groove 153 is curved, the drive groove 153 can push the roller 151 to move radially along the stator to multiple positions, thereby enabling the roller 151 to drive the distributor 140 to move radially along the stator between multiple positions.

[0139] Understandably, the position to which the splitter 140 moves is related to the position to which the roller 151 moves, and the position to which the roller 151 moves is related to the angle to which the drive groove 153 rotates. By controlling the drive disk 152 to drive the drive groove 153 to rotate within a first angle range, the splitter 140 can move between multiple positions along the radial direction of the stator, thereby enabling the splitter 140 to stretch the multi-layer conductors and thus separate the multi-layer conductors from each other.

[0140] In one possible embodiment, the drive groove 153 is configured to be waist-shaped.

[0141] By setting the groove wall of the drive groove 153 as a curved surface, the rotation of the drive groove 153 around the axis of the drive disk 152 can drive the roller 151 to move between multiple positions along the radial direction of the stator. In turn, the roller 151 drives the corresponding splitter 140 to move between equal positions along the radial direction of the stator, thereby enabling the splitter 140 to stretch the multi-layer conductors and separate the multi-layer conductors from each other.

[0142] like Figure 5 As shown, the first drive unit 150 further includes: a drive rod 154 connected to the drive disk 152; and a drive member 155 connected to the drive rod 154, wherein the drive member 155 can push the drive rod 154 to move so as to drive the drive disk 152 to rotate.

[0143] In this embodiment, the structure of the first drive unit 150 is defined. The first drive unit 150 includes a drive rod 154 and a drive member 155, wherein the drive rod 154 is connected to the drive disk 152, the drive member 155 is connected to the drive rod 154, and the drive member 155 is disposed on the mounting bracket 131. Specifically, the drive member 155 can push the drive rod 154 to move through a telescopic movement, thereby enabling the drive rod 154 to drive the drive disk 152 to rotate within a first angle range, thereby realizing the movement of the distributor 140 between multiple positions along the radial direction of the stator.

[0144] In one possible embodiment, the drive element 155 is a retractable electric cylinder.

[0145] By providing a drive rod 154 and a drive member 155 in the first drive unit 150, and connecting the two ends of the drive rod 154 to the drive disk 152 and the drive member 155 respectively, the drive member 155 can drive the drive disk 152 to rotate within a first angle range through the drive rod 154, thereby enabling the distributor 140 to move between multiple positions along the radial direction of the stator.

[0146] Example 6:

[0147] like Figure 6As shown, in a specific embodiment based on any of the above embodiments, the splitter device 130 further includes: a support plate 132 located between the plurality of splitters 140 and the mounting frame 131, the support plate 132 being used to support the plurality of splitters 140; a plurality of support blocks 133 disposed between the mounting frame 131 and the support plate 132; a plurality of support frames being used to support the support plate 132; the plurality of support blocks 133, the mounting frame 131 and the support plate 132 forming a receiving cavity 134; and a drive plate 152 located within the receiving cavity 134.

[0148] In this embodiment, to ensure the stability of the splitter 140, a support plate 132 for supporting the multiple splitters 140 is also provided in the splitter device 130. Specifically, the support plate 132 is located between the mounting bracket 131 and the multiple splitters 140, and the support plate 132 can support the multiple splitters 140 to ensure their stability. Further, the support plate 132 is located between the drive plate 152 and the multiple splitters 140. To avoid the multiple rollers 151, the support plate 132 is provided with multiple through holes for avoiding the rollers 151, through which the rollers 151 can pass and connect to the splitter 140. The multiple through holes are arranged one-to-one with the multiple rollers 151.

[0149] Furthermore, the branching device 130 is also provided with multiple support blocks 133, which are disposed between the mounting frame 131 and the support plate 132, and are used to support the support plate 132. The multiple support blocks 133, the mounting frame 131, and the support plate 132 together form a receiving cavity 134, and the drive plate 152 is located in the receiving cavity 134. Furthermore, in order to enable the drive plate 152 to rotate smoothly, a rotary bearing is also provided between the drive plate 152 and the mounting frame 131. The drive plate 152 is placed on the rotary bearing, and the rotary bearing is placed on the mounting frame 131. When the drive plate 152 is rotating, the rotary bearing between the drive plate 152 and the mounting frame 131 can eliminate the friction between the drive plate 152 and the mounting frame 131, so that the drive plate 152 can rotate smoothly.

[0150] By providing support plates 132 below multiple splitters 140, the splitters 140 can be supported to maintain stability. By providing multiple support blocks 133 between the support plates 132 and the mounting bracket 131, the support plates 132 can be supported by the support blocks 133, and the support blocks 133, the support plates 132, and the mounting bracket 131 together form a receiving cavity 134 for accommodating the drive plate 152 and the slewing bearing. This avoids the drive plate 152 occupying additional installation space and is beneficial for the miniaturization design of the flaring device 100.

[0151] Furthermore, the flaring device 100 also includes: a plurality of brackets 112 disposed on the mounting platform 110; a positioning device 120 including a positioning plate 121, the positioning plate 121 having a stator cavity 122 for accommodating the stator, the positioning plate 121 being connected to one end of the brackets 112 away from the mounting platform 110; and a splitter device 130 being movably connected to at least one of the plurality of brackets 112, the splitter device 130 being capable of moving to a first position in the direction toward the positioning plate 121, or moving to a second position in the direction away from the positioning plate 121.

[0152] In this embodiment, a plurality of brackets 112 are provided on the mounting platform 110, and a positioning plate 121 is provided in the positioning device 120. The positioning plate 121 has a stator cavity 122 for accommodating the stator. The positioning plate 121 is connected to the end of the bracket 112 away from the mounting platform 110, and the bracket 112 fixes the positioning plate 121. When the positioning device 120 fixes the stator core, the stator core is located in the stator cavity 122, and a certain distance is left between the stator core and the mounting platform 110, so that the branching device 130 can be set between the fixed stator core and the mounting platform 110.

[0153] Furthermore, in order to enable the wire distribution device 130 to move along the axial direction of the stator core between a first position and a second position, either toward or away from the stator core, this application movably connects the wire distribution device 130 to at least one of a plurality of supports 112, allowing the wire distribution device 130 to reciprocate along the extending direction of the support 112. In this way, the support 112 can both fix the wire distribution device 130 and guide it.

[0154] In one possible embodiment, there are two brackets 112, which are respectively disposed on both sides of the splitter device 130. The splitter device 130 is movably connected to one of the brackets 112, and the two ends of the positioning plate 121 are respectively fixedly connected to the two brackets 112.

[0155] By setting multiple brackets 112 on the mounting platform 110 and movably connecting the splitter device 130 to at least one of the multiple brackets 112, the splitter device 130 can be fixed by the brackets 112 on the one hand, and the splitter device 130 can be guided by the brackets 112 on the other hand, so that the splitter device 130 can move back and forth between the first position and the second position along the brackets 112.

[0156] Example 7:

[0157] like Figure 1 , Figure 2 and Figure 7As shown, in a specific embodiment based on any of the above embodiments, the flaring device 100 further includes: a guide rail 113 disposed on at least one of the plurality of brackets 112; a walking device disposed on the mounting frame 131, the walking device being adapted to the guide rail 113; and a second drive unit 111 disposed on the mounting platform 110, the second drive unit 111 being electrically connected to the walking device, the second drive unit 111 being used to drive the walking device to move along the guide rail 113.

[0158] In this embodiment, in order for the splitter device 130 to reciprocate between the first and second positions along the bracket 112, a component for enabling the splitter device 130 to move needs to be provided on the bracket 112 to which the splitter device 130 is connected. Specifically, at least one of the brackets 112 is also provided with a guide rail 113, and a traveling device adapted to the guide rail 113 is provided on the mounting frame 131 of the splitter device 130. The traveling device is movably connected to the guide rail 113, and the traveling device can drive the mounting frame 131 to reciprocate between the first and second positions along the guide rail 113 under the drive of an external force.

[0159] Furthermore, the second drive unit 111 is connected to the walking device. The second drive unit 111 can drive the walking device to move along the guide rail 113, thereby enabling the walking device to drive the mounting frame 131 to move between the first position and the second position, thereby realizing the movement of multiple splitters 140 along the stator axis, so that the splitters 140 can stretch the multi-layer conductors in sequence, so that the multi-layer conductors can be separated from each other.

[0160] Furthermore, the second drive unit 111 is disposed on the mounting platform 110. In one possible embodiment, the second drive unit 111 is an electric cylinder.

[0161] By providing a guide rail 113 on at least one of the multiple brackets 112 and a traveling device adapted to the guide rail 113 on the mounting frame 131, the traveling device can be driven to move along the guide rail 113 by the second drive unit 111. The traveling device can drive the mounting frame 131 to reciprocate between a first position and a second position, thereby realizing the movement of multiple splitters 140 along the stator axis. This allows the splitters 140 to stretch multiple layers of conductors sequentially, thus separating the multiple layers of conductors. In addition, the connection between the traveling device and the guide rail 113 can also fix the splitter 130.

[0162] Example 8:

[0163] like Figure 8 and Figure 9As shown, in a specific embodiment based on any of the above embodiments, the positioning device 120 further includes: a plurality of guide members 123, disposed on the side of the positioning plate 121 away from the mounting platform 110, each guide member 123 having a guide groove 124, the groove opening of the guide groove 124 facing the stator cavity 122.

[0164] In this embodiment, to facilitate the placement of the stator core into the stator cavity 122 of the mounting plate, a plurality of guide members 123 are also provided in the positioning device 120. The guide members 123 are used to guide the stator core so that the stator core can be accurately inserted into the stator cavity 122. The guide members 123 are located on the side of the positioning plate 121 away from the mounting platform 110. During the process of the stator being inserted into the stator cavity 122 from the side of the positioning plate 121 away from the mounting platform 110, the guide members 123 first guide the stator so that the stator can be accurately inserted into the stator cavity 122.

[0165] Furthermore, each guide member 123 is provided with a guide groove 124. The opening of the guide groove 124 is located at the edge of the stator cavity 122 and faces the stator cavity 122. The guide grooves 124 of multiple guide members 123 surround a nearly circular area, thereby guiding the stator during the process of inserting the stator into the stator cavity 122, so that the stator can be accurately inserted into the stator cavity 122.

[0166] By providing multiple guide members 123 on the side of the positioning plate 121 away from the mounting platform 110, the stator can be guided by the multiple guide members 123, so that the stator can be accurately inserted into the stator cavity 122.

[0167] like Figure 7 As shown, the stator further includes a rotor cavity, and the positioning device 120 also includes: a positioning post 114; and a plurality of tensioning blocks 115, any one of which is movably connected to the positioning post 114. When the stator is located in the stator cavity 122, the plurality of tensioning blocks 115 can move radially away from the positioning post 114 to abut against the wall of the rotor cavity.

[0168] In this embodiment, the structure of the positioning device 120 is further defined. The stator to be fixed by the positioning device 120 includes a rotor cavity, and the positioning device 120 can fix the stator core by pressing against the wall of the rotor cavity. Specifically, the positioning device 120 also includes a positioning post 114 and a plurality of tensioning blocks 115. The plurality of tensioning blocks 115 are circumferentially disposed on the positioning post 114, and the tensioning blocks 115 can move radially relative to the positioning post 114. After the stator core moves into place in the stator cavity 122, the plurality of tensioning blocks 115 are located in the rotor cavity. The plurality of tensioning blocks 115 move radially toward the wall of the rotor cavity until the tensioning blocks 115 abut against the wall of the rotor cavity. Then, the tensioning blocks 115 continue to move, thereby pressing the inner wall of the rotor cavity with the plurality of tensioning blocks 115 to fix the stator core.

[0169] Furthermore, when it is necessary to remove the stator from the positioning device 120, the plurality of tensioning blocks 115 can move radially toward the positioning post 114 along the stator core to separate the plurality of tensioning blocks 115 from the stator core, so that the stator can be removed from the positioning device 120.

[0170] In one possible embodiment, the number of tensioning blocks 115 is three, and the three tensioning blocks 115 are evenly distributed along the circumference of the positioning post 114.

[0171] By setting a positioning post 114 and a plurality of tensioning blocks 115 in the positioning device 120, the wall surface of the rotor cavity in the stator core can be pressed by the plurality of tensioning blocks 115 to fix the stator core.

[0172] Furthermore, the positioning device 120 also includes a third drive unit 116, which is connected to a plurality of tensioning blocks 115, and the third drive unit 116 is used to drive the tensioning blocks 115 to move radially.

[0173] In this embodiment, to enable the multiple tension blocks 115 to move radially along the stator, the positioning device 120 is further provided with a third driving unit 116 connected to the multiple tension blocks 115. The third driving unit 116 is disposed on the positioning post 114 and can drive the multiple tension blocks 115 to move in a direction toward or away from the positioning post 114. When the stator moves into the stator cavity 122, the third driving unit 116 drives the tension blocks 115 to move in a direction away from the positioning post 114, so that the multiple tension blocks 115 can abut against the wall of the rotor cavity, thereby fixing the stator core by preventing the multiple tension blocks 115 from squeezing the rotor cavity. When the stator needs to be removed from the stator cavity 122, the third driving unit 116 drives the multiple tension blocks 115 to move in a direction toward the positioning post 114, and the multiple tension blocks 115 separate from the stator core, thereby allowing the stator to be removed from the stator cavity 122.

[0174] By providing a third drive unit 116 connected to multiple tension blocks 115 in the positioning device 120, the multiple tension blocks 115 can be driven to move in a direction toward or away from the positioning post 114, so that the tension blocks 115 can squeeze the inner wall of the rotor cavity and fix the stator core.

[0175] Example 9:

[0176] like Figure 8 and Figure 9 As shown, in a specific embodiment based on any of the above embodiments, the flaring device 100 further includes: a protective disk 125, disposed on the side of the positioning plate 121 facing the mounting platform 110, the inner edge of the protective disk 125 protruding from the cavity wall of the stator cavity 122, and the inner edge of the protective disk 125 being provided with a plurality of slits 126, the slits 126 being used to allow wires to pass through.

[0177] In this embodiment, since slot paper is usually installed in the slots of the stator core, in order to prevent the wire splitting device 130 from damaging the slot paper during the pulling of the multi-layer conductors, a protective disc 125 for protecting the slot paper is also provided in the flaring device 100.

[0178] Specifically, the protective disc 125 is located on the side of the positioning plate 121 facing the mounting platform 110. The protective disc 125 is constructed as a ring structure, with its inner edge protruding from the cavity wall of the stator cavity 122. When the stator core is located inside the stator cavity 122, the inner edge of the protective disc 125 protruding from the cavity wall of the stator cavity 122 can shield the slot paper in the tooth groove, thereby protecting the slot paper.

[0179] Furthermore, to allow the conductors of each layer to pass through the protective disc 125 so that the conductors can be stretched by the wire distribution device 130, a plurality of slits 126 for the conductors to pass through are provided on the inner edge of the protective disc 125. When the stator core is located in the stator cavity 122, the conductors of each layer can pass through the protective disc 125 through the slits 126. On the one hand, the protective disc 125 can protect the slotted paper, and on the other hand, it can prevent interference between the conductors and the protective disc 125.

[0180] Furthermore, the flaring device 100 also includes a fourth drive unit 127, which is disposed on the positioning plate 121. The fourth drive unit 127 is connected to the protective plate 125 and is used to drive the protective plate 125 to rotate within a second angle range.

[0181] In this embodiment, the flaring device 100 is further provided with a fourth drive unit 127 for adjusting the rotation angle of the protective disc 125. Understandably, if the slits 126 on the protective disc 125 cannot be aligned with the wire, the wire cannot pass smoothly through the protective disc 125. To ensure that the multiple slits 126 on the protective disc 125 can be aligned with the wire, the flaring device 100 is further provided with a fourth drive unit 127 for driving the protective disc 125 to rotate. The fourth drive unit 127 can drive the protective disc 125 to rotate within a second angle range, thus adjusting the protective disc 125 to a suitable position so that each slit 126 can be aligned with the wire, allowing the wire to pass smoothly through the slits 126, facilitating the stretching of each layer of wires by the wire splitting device 130.

[0182] like Figure 9 As shown, the flaring device 100 further includes: a limiting block 128 connected to the protective plate 125; and multiple stop members 129 connected to the positioning plate 121. The multiple stop members 129 are located on both sides of the limiting block 128. When the protective plate 125 drives the limiting block 128 to rotate, the stop members 129 can abut against the limiting block 128.

[0183] In this embodiment, to limit the angular range within which the protective disc 125 can rotate, the flaring device 100 is further provided with a limiting block 128 and multiple stop members 129 for circumferentially limiting the limiting disc. The limiting block 128 is connected to the protective disc 125, and the multiple stop members 129 are connected to the positioning plate 121, with the multiple stop members 129 located on both sides of the limiting block 128. Specifically, when the fourth drive unit 127 drives the protective disc 125 to rotate, the protective disc 125 drives the limiting block 128 to rotate together. When the limiting block 128 abuts against the stop member 129 located on one side of the limiting block 128, the limiting block 128 cannot continue to move, thereby preventing the protective disc 125 from moving further. In this way, the multiple stop members 129 can limit the protective disc 125, allowing the protective disc 125 to rotate within a second angular range.

[0184] In one possible embodiment, the stop member 129 includes a mounting member and screws. The mounting member is fixedly connected to the positioning plate 121, and the mounting member has threaded holes. The screws are connected to the mounting member through the threaded holes. The position of the screws is adjustable. By adjusting the distance between the screws located on both sides of the limiting block 128, the angle range of the second angle can be adjusted.
