Description

Technical Field

[0001] The present invention relates to the technical field of hairpin motors, and more specifically to a flat copper wire stator winding device with excellent winding effect.

Background Art

[0002] Hair pin permanent magnet synchronous motors are gradually being widely applied in the domestic drive motor market in China. Compared with conventional wound motors, due to the flat characteristics of Hairpin copper wires, under the same power, the volume of the motor is smaller, the power is higher, which is the development direction of the next-generation new energy drive motors. The conventional manual insertion of copper wires into the core is inefficient. Automatic wire insertion production, due to its high efficiency, high flexibility, and intelligence, etc., is becoming the future trend for the installation of flat copper wires (a type of copper wire with a rectangular cross-section finished) of Hair pin permanent magnet synchronous motors. Currently, when winding the flat copper wire around the winding in the stator core, since the flat copper wire is in the shape of a hairpin, it is necessary to manually wind the flat copper wire continuously around the stator core during production. In this way, the processing efficiency is reduced, the labor intensity is high, and continuous winding work cannot be carried out on the stator core, and the large production demand cannot be met.

[0003] In order to solve the above problems, the Chinese invention patent with the application number CN202211092185.4 discloses a flat copper wire stator winding device. This flat copper wire stator winding device includes a table, a moving mechanism installed on the table, a rotating mechanism, and a regulating mechanism. The moving mechanism includes a jack-up assembly slidably installed on the table, a moving plate connected to the upper end of the jack-up assembly, and an elastic clamp fixed to the moving plate. The rotating mechanism includes a pedestal fixed to the table, a driving member connected to the pedestal, and a driven member installed on the table. Although it can perform continuous winding work on the stator core mechanically to improve production efficiency, the winding effect of this flat copper wire stator winding device is not good.

[0004] Therefore, in order to solve the above problems, it is necessary to propose a flat copper wire stator winding device with excellent winding effect.

Embodiments for Carrying out the Invention

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained on the premise that those skilled in the art do not pay creative labor belong to the protection scope of the present invention.

[0024] Referring to FIGS. 1-11, it is a flat copper wire stator winding device with excellent winding effect, including a tool 2 for arranging flat copper wires installed on the stator winding device, a winding mechanism for winding the arranged flat copper wires, a flat copper wire conveying mechanism, and a tool conveying mechanism. The tool conveying mechanism is used to convey the tool 2 to the winding mechanism. The winding mechanism is installed on the fixed frame 10, and the tool conveying mechanism is installed below the winding mechanism. The flat copper wire conveying mechanism is used to convey the flat copper wires arranged on the tool 2 conveyed to the winding mechanism to the winding mechanism for winding. The flat copper wire conveying mechanism is installed on the fixed frame 10 and is distributed on both sides of the winding mechanism.

[0025] In this embodiment, through the fitting installation of the tool conveying mechanism and the flat copper wire conveying mechanism, the arranged flat copper wires can be conveyed to the winding mechanism for winding.

[0026] Specifically, as shown in FIG. 1, the tool conveyance mechanism includes a line 1 for conveying the tool 2. The tool 2 includes a wire alignment plate and a support plate assembly. The wire alignment plate is located on the support plate assembly, and adjustment assemblies are installed on both sides of the support plate assembly. The adjustment assembly can push the support plate assembly so as to contact the flat copper wire on the wire alignment plate, align the flat wires. During use, according to the winding requirements, flat copper wires of different specifications are arranged on the wire alignment plate. The adjustment assembly pushes the support plate assembly so as to contact the flat copper wire on the wire alignment plate until both ends of the flat copper wire are aligned. Then the adjustment assembly resets, and the support plate assembly resets and no longer contacts the flat copper wire, facilitating subsequent winding. A sliding belt is installed on the line 1. The support plate assembly is located on the sliding belt. The sliding belt is driven by a drive assembly, thereby moving the entire tool 2.

[0027] Specifically, as shown in FIG. 1, the flat copper wire conveyance mechanism includes a wire passing portion 3 that can slide along the left-right direction and conveys the flat copper wire in the tool 2 to the winding mechanism, and a wire guiding portion 4 that can slide along the left-right direction and prevents the flat copper wire wound by the winding mechanism from falling off. The wire passing portion 3 and the wire guiding portion 4 are distributed on the fixed frames 10 on both sides of the winding mechanism. The wire passing portion 3 includes a wire moving assembly 33 for conveying the flat copper wire in the tool 2 to the winding mechanism. The wire moving assembly 33 is driven by a first drive assembly to move up and down. As shown in FIG. 2, the wire passing portion 3 includes a first mounting base 30, a first cylinder 31, a first drive assembly, and a wire movement assembly 33. The first drive assembly is a second cylinder 32. The first mounting base 30 is a right-angle plate divided into a vertical plate and a horizontal plate. The horizontal plate is slidably disposed along the left-right direction on the fixed frames 10 on both sides of the winding mechanism. The first cylinder 31 is fixedly connected to the fixed frame 10 located on one side of the wire passing portion 3. The output end of the first cylinder 31 is fixed to the horizontal plate and is used to push the horizontal plate so as to move toward or away from the winding mechanism. The vertical plate is installed at the end of the horizontal plate facing the winding mechanism. A second cylinder 32 with its output end facing downward is fixedly connected to the upper end of the vertical plate. The wire movement assembly 33 is fixedly connected to the output end of the second cylinder 32 and is slidably disposed on the vertical plate. To ensure that the wire movement assembly 33 is more stable when moving, the second cylinder 32 can adjust the height position of the wire movement assembly 33 in the vertical direction so as to adapt to the position of the winding mechanism, facilitating accurate fitting with the winding mechanism. As shown in Fig. 2, the wire guide portion 4 includes a second mounting base 40, a third cylinder 41, a wire guide block 42, and a second drive assembly. The second mounting base 40 is a right-angle plate that coincides with the shape of the first mounting base 30. The second drive assembly is a fourth cylinder 43. The installation forms of the second mounting base 40, the third cylinder 41, and the fourth cylinder 43 are the same as those of the first mounting base 30, the first cylinder 31, and the second cylinder 32. However, the wire guide portion 4 and the wire passing portion 3 are symmetrically distributed with respect to the winding mechanism, and there are further differences. The wire guide block 42 is fixedly connected to the output end of the second cylinder 32. The wire guide block 42 is slidably arranged on the vertical plate of the second mounting base 40 with the shape of a right-angle plate to ensure the stability of the wire guide block 42 during sliding. By the fitting installation of the third cylinder 41 and the fourth cylinder 43, the wire guide block 42 can be located at the optimal operating position during the operation of the winding mechanism. The function of the wire guide block 42 is to prevent the flat copper wire from falling off when the winding mechanism winds the flat copper wire. The surface of the wire guide block 42 that fits the winding mechanism should be an arc-shaped surface that is the same as the radian of the rotation trajectory of the winding mechanism, and the upper end of the arc-shaped surface should be higher than the horizontal plane of the axis of the winding mechanism, so that the arc-shaped surface can be closely adhered to the winding mechanism by the winding mechanism. As shown in Figs. 2 and 3, two sets of wire movement assemblies 33 are installed. Each set of wire movement assemblies 33 includes a sliding plate 34, two baffle plates 35, a first motor 36, and a conveyor belt 37. The side of the baffle plate 35 facing the winding mechanism is also provided as an arc-shaped surface. The sliding plate 34 is slidably arranged on the vertical plate of the first mounting base 30 with the shape of a right-angle plate. The first motor 36 and the conveyor belt 37 are both installed between the two baffle plates 35. The first motor 36 moves the conveyor belt 37 through the cooperation of rollers. The entire conveyor belt 37 is inclined, and the end of the conveyor belt 37 facing the sliding plate 34 is higher than the other end. Also, the upper end of the conveyor belt 37 should ensure a smooth transition with the arc-shaped surface of the baffle plate 35, thereby better realizing the conveyance of the flat copper wire.

[0028] Specifically, as shown in FIGS. 3 and 4, the stator winding device further includes a positioning portion 7 for attaching a winding mechanism. The positioning portion 7 is used to adjust the position of the winding mechanism. The winding mechanism further includes a wire winding portion 5. The wire winding portion 5 includes a winding assembly 55 for winding a flat copper wire. The wire winding portion 5 is detachably attached to a manipulator. When winding a wire, the manipulator places the wire winding portion 5 at a winding station. After winding the wire, the manipulator directly moves the wire winding portion 5 to a corresponding station in the subsequent flat copper wire processing process. The winding assembly 55 is driven by a third drive assembly to rotate, and the inner and outer diameters of the winding assembly 55 are variable. The winding assembly 55 includes a bush 57 in which a plurality of insertion grooves 53 are formed. Cover plates are fixedly connected to both ends of the bush 57. Insertion sheets 58 are slidably connected to each insertion groove 53 along the height direction of the insertion groove 53. The plurality of insertion sheets 58 and the insertion grooves 53 are distributed in an annular array. A space for winding a flat copper wire is formed between every two insertion sheets 58. At least two umbrella-shaped members 59 for sliding the insertion sheets 58 are slidably provided in the axial direction of the bush 57. The umbrella-shaped members 59 are fixed to a rotating shaft 56 that overlaps the central axis of the bush 57. A chute 11 that is inclined by a certain angle is formed on the side of the insertion sheet 58 facing the rotating shaft 56. An extension rod inserted into the chute 11 is fixedly connected to the end of the umbrella-shaped member 59 with a larger opening. Both ends of the rotating shaft 56 are slidably connected to two cover plates, thereby changing the position of the insertion sheet 58 in the insertion groove 53 and further changing the outer diameter formed by the insertion sheets 58. As shown in FIGS. 3 and 4, the wire winding portion 5 further includes a mounting base 50, a fifth cylinder 51, a fourth drive assembly 52, a locking assembly 9, and a sliding base 54. The manipulator controls the mounting base 50 to control the detachment of the wire winding portion 5. The fourth drive assembly 52 includes a servo motor 12 and a hollow reducer 13. The input shaft of the hollow reducer 13 is fixedly connected to the output shaft of the servo motor 12. The output end of the hollow reducer 13 is fixedly connected to the cover plate on the side of the winding assembly 55 facing the fifth cylinder 51. Thus, the servo motor 12 can rotate the bush 57 through the hollow reducer 13. As shown in FIGS. 8 and 10, the sliding base 54 is slidably connected along the front-rear direction to the lower end of the mounting base 50, and the locking assembly 9 is installed on the sliding base 54. The locking assembly 9 includes a ninth cylinder 90, a steel ball 91, a rotary joint 92, and a sliding sleeve 93. The fifth cylinder 51 is fixedly attached to the rear end of the mounting base 50, and the output end of the fifth cylinder 51 is fixed to the sliding base 54 and is used to control the sliding base 54 to slide back and forth. The rotary joint 92 is fixedly connected to the central portion of the sliding base 54. The rotating shaft 56 penetrates through the cover plate and is rotatably connected to the inner surface of the rotary joint 92. The other end of the rotating shaft 56 is slidably connected to a hollow cylinder, and the hollow cylinder is fixed inside the cover plate at the end of the bush 57 away from the rotary joint 92. The support of the rotating shaft 56 for the winding assembly 55 can be made more stable. The ninth cylinder 90 is fixedly connected to the sliding base 54. The sliding sleeve 93 covers the outside of the rotary joint 92. The end of the sliding sleeve 93 away from the rotary joint 92 is fixed to the output end of the ninth cylinder 90. The axes of the rotating shaft 56, the sliding sleeve 93, and the rotary joint 92 are all on the same axis. The rotary joint 92 is installed through the sliding base 54. The sliding sleeve 93 covers one end of the rotary joint 92, and the rotating shaft 56 is inserted into the inside of the other end of the rotary joint 92. At this time, it can ensure the realization of the purpose that the rotating shaft 56 can reciprocate along the front-rear direction, and the rotating shaft 56 can rotate according to the bush 57. A steel ball 91 is movably connected to the side of the rotary joint 92 facing the sliding sleeve 93. An annular groove for the steel ball 91 to roll is opened at the end of the rotating shaft 56 facing the sliding sleeve 93. A protrusion for pressing the steel ball 91 is installed at the rear end of the inner surface of the sliding sleeve 93, so that the steel ball 91 penetrates through the rotary joint 92 and is locked in the annular groove at the end of the rotating shaft 56. With this installation, when it is necessary to remove the winding assembly, the ninth cylinder 90 contracts, the sliding sleeve 93 shrinks from the rotary joint 92, and when the rotating shaft 56 is pulled out from the rotary joint 92, most of the rotary joint 92 is pushed into the sliding sleeve 93 through the steel ball 91, so that the rapid removal of the winding assembly 55 can be completed.

[0029] Specifically, as shown in FIG. 5, the winding mechanism further includes a wire clamp assembly 8 for clamping a winding assembly 55 around which a flat copper wire is wound. The wire clamp assembly 8 includes a pedestal 80, a first mounting block symmetrically and fixedly connected to the upper end surface of the mounting base 50, a tenth cylinder 81 hingedly connected to the first mounting block, a first swing arm 83 rotatably connected to both sides of the bottom of the pedestal 80, a second swing arm 84 rotatably connected to the end of the first swing arm 83 away from the pedestal 80, a second mounting block fixedly connected to the second swing arm 84, an eleventh cylinder 82 hingedly connected to the second mounting block, a driving gear 85, a driven gear 86, and a belt 87. The pedestal 80 is installed on the lower end surface of the mounting base 50. The output end of the tenth cylinder 81 is rotatably connected to the first swing arm 83. The driving gear 85 is rotatably installed at the end of the first swing arm 83 away from the pedestal 80. The driven gear 86 is rotatably connected to the hinge connection point between the first swing arm 83 and the second swing arm 84, and the axis of the driven gear 86 is coaxial with the hinge connection point between the first swing arm 83 and the second swing arm 84. The driving gear 85 is installed in mesh with the driven gear 86. A connection post is installed at a position on the surface of the driving gear 85 radially away from the center of the driving gear 85. The output end of the eleventh cylinder 82 is rotatably connected to the connection post. The end of the belt 87 is fixedly connected to the side of the winding assembly 55 of the second swing arm 84 opposite to the center. When the tenth cylinder 81 and the eleventh cylinder 82 drive the first swing arm 83 and the second swing arm 84 to clamp the winding assembly 55, the belt 87 just wraps around the outer surface of the winding assembly 55 to prevent the flat copper wire from falling off.

[0030] Specifically, as shown in FIG. 9, the tool transport mechanism further includes a jack-up portion 6 that can slide along the left-right direction and jacks up the tool 2, and is used to accurately transport and wind the flat copper wire in the tool 2 to the winding assembly 55. The jack-up portion 6 includes a bottom frame, sliding rails 60 symmetrically and fixedly connected to the bottom frame, a sliding plate 61 slidably connected to the sliding rails 60, a horizontally placed plate 62 slidably arranged along the vertical direction on the sliding plate 61, a positioning rod 63 fixedly connected to the horizontally placed plate 62, a rack 64 fixedly connected to the bottom frame, a third motor 65 fixedly connected to the sliding plate 61, a first gear 66 fixedly connected to the output shaft of the third motor 65, and a sixth cylinder 67 fixedly connected to the lower end surface of the sliding plate 61. The output shaft of the sixth cylinder 67 penetrates the sliding plate 61 and is used to slide the horizontally placed plate 62 upward. The first gear 66 is meshed and connected with the rack 64. The third motor 65 is used to drive the first gear 66 to rotate. Due to the mutual meshing of the first gear 66 and the rack 64, the sliding plate 61 is linearly reciprocated along the sliding rails 60. When the tool 2 slides in the direction approaching the wire winding portion 5 along line 1, the sixth cylinder 67 pushes up the horizontally placed plate 62, so that the positioning rod 63 jacks up the tool 2 so as to disengage from line 1. The horizontally placed plate 62 slides along the sliding rails 60 and approaches the wire winding portion 5. To improve the operating efficiency, other jack-up portions 6 can continue to transport the tool 2, and the previous jack-up portion 6 can continue to receive the new tool 2 to ensure the continuity of the winding operation.

[0031] Specifically, as shown in FIGS. 3, 6, and 7, a fixing plate 70 is fixedly connected to a fixing frame 10 at the front end of the winding assembly 55. A seventh cylinder 71 is fixedly connected to the lower end of the fixing plate 70. The output end of the seventh cylinder 71 penetrates the fixing plate 70 and is fixedly connected to a transition plate. An eighth cylinder 72 is fixedly connected to the transition plate. By adjusting the height and front-rear position of the entire wire winding portion 5, the wire winding portion 5 can be centered on the flat copper wire conveying mechanism, and the winding assembly 55 can be better fitted to the arc-shaped surfaces in the wire passing portion 3 and the wire guiding portion 4. Thereby, the dropping of the flat copper wire can be effectively prevented. The output end of the eighth cylinder 72 faces the winding assembly 55 and is fixedly connected to a movable block 73. A positioning block 74 for engaging with the cover plate on the side of the bush 57 facing the movable block 73 is rotatably connected to the end of the movable block 73 facing the winding assembly 55. At least two groove bodies are opened on the side of the positioning block 74 facing the winding assembly 55. At least two insertion bodies corresponding to the distribution of the groove bodies are opened on the cover plate on the side of the bush 57 facing the movable block 73. When the wire winding portion 5 is placed on the fixing frame 10, the seventh cylinder 71 jacks up the fixing plate 70, the eighth cylinder 72 adjusts the position height of the positioning block 74, and the eighth cylinder 72 pushes the movable block 73 to approach the wire winding portion 5, covering the groove body with the insertion body and realizing the effect of locking between the positioning block 74 and the cover plate. Thereby, by controlling the seventh cylinder 71 and the eighth cylinder 72, centering adjustment is performed on the wire winding portion 5 to ensure that the wire winding portion 5 is in the correct winding position and ensure the winding effect in the later stage.

[0032] The operating principle is as follows. First, the manipulator arranges the flat copper wire on tool 2, and conveyor line 1 transports tool 2 to a predetermined position. After reaching the predetermined position, the sixth cylinder 67 extends to lift tool 2. After lifting it to the predetermined position, the third motor 65 starts to rotate the first gear 66. Due to the meshing of the rack 64, the sliding plate 61 slides the entire jack-up part 6 along the sliding rail 60 to the lower end of the winding assembly 55. By adjusting the position of the winding assembly 55 with the positioning part 7, the wire guide part 4, and the wire passing part 3, the insertion sheet 58 in the winding assembly 55 can be made to adhere closely to the arc-shaped surface. When the first motor 36 in the wire passing part 3 starts to operate, at the same time, the servo motor 12 also starts, so that the conveyor belt 37 transports the flat copper wire to the winding assembly 55. The winding assembly 55 winds the flat copper wire. Due to the installation of the arc-shaped surface, when the winding assembly 55 makes one full turn, the flat copper wire will not fall off from the gap between the two insertion sheets 58. At the same time, by activating the wire clamping assembly 8, the tenth cylinder 81 extends to rotate the first swing arm 83. At the same time, the eleventh cylinder 82 performs a reciprocating telescoping motion, so that the eleventh cylinder 82 rotates the driving gear 85. Further, the driving gear 85 rotates the driven gear 86 to rotate the second swing arm 84. At the same time, the belt 87 is wound around the outside of the winding assembly 55 to further prevent the flat copper wire from falling off. After the clamping operation is completed, when the manipulator directly moves the wire winding part 5 to the wire insertion station in the stator processing process, the wire clamping assembly 8 is loosened, and the wound flat copper wire coil is inserted into the wire insertion tool at the corresponding wire insertion station. Then, another manipulator replaces and operates the next wire winding part 5. When replacing the following winding part 5, other manipulators are controlled to insert the winding part 5 into the alignment block 74 towards the insertion body on one side of the positioning part 7, complete the attachment of the winding part 5, and, to facilitate the cooperation between the winding assembly 55 and the wire passing part 3, the wire guide part 4, the jack-up part 6 and the tool 2, the seventh cylinder 71 and the eighth cylinder 72 are used to adjust the height and the position along the front-rear direction of the winding part 5 respectively. By alternately operating the two manipulators, it is not necessary to frequently replace the winding part 5. When adjusting the position of the insertion groove 53 of the insertion sheet 58, by controlling the expansion and contraction of the fifth cylinder 51, the sliding base 54 is pushed to slide along the mounting base 50. The mounting base 50 slides the rotary joint 92, and further slides the rotary shaft 56 by the rotary joint 92. The rotary shaft 56 slides the umbrella-shaped member 59, adjusts the length of the extending rod protruding into the chute 11, and further adjusts the position of the insertion groove 53 of the insertion sheet 58, thereby changing the size of the outer diameter of the winding assembly 55.
