Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and in particular to a tooling for threading motor coil leads. Background Technology

[0002] In the assembly process of a brushless DC motor with sensors, a Hall effect board is required to detect the rotor position. To save space, the three-phase lead-out board is usually integrated onto the Hall effect board and installed on the inner wall or bottom of the stator assembly. Sensorless brushless motors do not have a Hall effect board; they only have a three-phase lead-out board. When installing the PCB board, the leads of the copper coils fixed inside the stator need to pass through pre-drilled holes on the PCB board (either the integrated board of the Hall effect board and the three-phase lead-out board or the three-phase lead-out board itself) and be soldered (e.g., ...). Figure 1 (As shown).

[0003] Because the PCB board is located at the bottom of the stator cavity, and the perforations on the PCB board are small, and the copper coil leads are thin and flexible, it is difficult for manual or ordinary robotic arms to accurately pass the copper coil leads through the perforations on the PCB board within a limited space.

[0004] In existing technologies, the copper coil leads are usually passed through pre-drilled holes in the PCB board manually using tweezers. This not only results in low production efficiency and high labor intensity, but also makes it difficult to achieve automated continuous production. Summary of the Invention

[0005] The purpose of this invention is to provide a tooling for threading motor coil leads, which aims to solve the problems mentioned above, such as the difficulty of manually threading copper coil leads through pre-drilled holes in PCB boards, resulting in low production efficiency and high labor intensity.

[0006] The technical solution adopted in this invention to solve the technical problem is as follows: a tooling for threading motor coil leads, comprising: The base plate has a positioning seat installed at its upper end, which is used to place and position the stator. A lifting component is installed at the upper end of the base plate and directly above the positioning seat. The lifting component is used to grip the PCB board and push it toward the stator. The wire gripping component is installed on one side of the lifting component. It moves synchronously with the lifting component and is used to grip the lead wire of the copper coil inside the stator and pass it through the reserved hole on the PCB board.

[0007] The present invention also has the following technical features: In one embodiment of the present invention, an adjustment component is installed on the upper end of the base plate, and the positioning seat is fixedly installed on the upper end of the adjustment component. The adjustment component is used to adjust the inner diameter of the positioning seat.

One end of the limiting plate is fixed to the outer wall of the electric push rod and is circumferentially distributed.

[0009] In one embodiment of the present invention, the wire gripping component includes a movable ring and a support ring. The movable ring is slidably sleeved on the outside of the drive rod. A movable sleeve is fixedly installed at one end of the movable ring, and a spring is fixedly connected to the other end. A fixed ring is fixedly installed at the end of the spring away from the movable ring, and the fixed ring is fixed to the side wall of the drive rod.

A wire guide slope is provided on one side of the lower end of the wire gripping plate. An arc-shaped hook plate is fixedly installed on the upper end of the wire gripping plate near the wire guide slope. A lead plate is fixedly installed on the end of the hook plate away from the wire gripping plate.

[0013] In one embodiment of the present invention, a pressure plate is rotatably connected to the upper end of the wire gripping plate away from the conductor slope via a torsion spring. When the torsion spring is in a balanced state, the pressure plate and the wire gripping plate are perpendicular.

[0014] In one embodiment of the present invention, the driving assembly includes a motor, a gear ring, and a plurality of driven gears. The motor is fixed to the outer end of the output shaft of the electric push rod. A hexagonal prism is fixedly installed on the output shaft of the motor. A sleeve is slidably sleeved on the outer end of the hexagonal prism. A driving gear is fixedly installed on the lower end of the sleeve.

The lifting component resets, the stator with the PCB board installed is removed, and a new nail is inserted, realizing continuous production and improving production efficiency.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0020] The illustrations provided in this embodiment are only intended to illustrate the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the shape, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] It should be noted that during the assembly of a brushless DC motor with sensors, a Hall effect sensor is required to detect the rotor position. To save space, the three-phase lead-out board is usually integrated onto the Hall effect sensor and then mounted on the inner wall or bottom of the stator assembly. A brushless motor without sensors only has a three-phase lead-out board. The leads of the copper coils fixed inside the stator need to pass through the pre-drilled holes on the PCB board (the integrated board of the Hall effect sensor and the three-phase lead-out board, or the three-phase lead-out board itself) and be soldered.

[0022] In existing technologies, manual assistance is typically provided by using tweezers to pass the copper coil leads through the pre-drilled holes in the PCB board. Since the PCB board is located at the bottom of the stator cavity and the hole size on the PCB board is small, and the copper coil leads are thin and flexible, not only is the production efficiency low and the labor intensity high, but it is also difficult to achieve automated continuous production.

[0023] Please see Figures 2 to 12 This invention provides a technical solution: a motor coil lead threading fixture, comprising a base plate 10, with a positioning seat 40 mounted on the upper end. The positioning seat 40 is cylindrical, and the lower end of the stator 60 is inserted into the positioning seat 40. The positioning seat 40 is used to place and position the stator 60. A lifting component is disposed on the upper end of the base plate 10, and a support frame 11 is fixedly mounted on one side of the upper end of the base plate 10. The lifting component is fixed on the lower end of the support frame 11 and located directly above the positioning seat 40. The lifting component is used to grip the PCB board 70 and push it toward the stator 60. A wire gripping component is installed on one side of the lifting component and moves synchronously with the lifting component. The wire gripping component is used to grip the lead of the copper coil 61 inside the stator 60 and pass it through a reserved hole on the PCB board 70 so that the lead can be subsequently soldered to the upper end of the reserved hole on the PCB board 70.

[0024] The PCB board 70 is transported to the lower end of the lifting component by the robotic arm. The lifting component moves down and inserts into the hole in the middle of the PCB board 70 to fix it. At the same time, the lower end of the wire gripping component passes through the corresponding reserved hole and rotates 360 degrees to grip the copper coil 61 lead wire placed in the stator 60 in the positioning seat 40. Then the lifting component continues to drive the PCB board 70 to move down, and the gripped lead wire follows the wire gripping component through the reserved hole of the PCB board 70.

[0025] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The lifting component includes an electric push rod 20 and multiple limiting plates 21. One end of the electric push rod 20 is fixed to the top of the support frame 11. The electric push rod 20 and the stator 60 fixed in the positioning seat 40 are coaxial. The output shaft of the electric push rod 20 is fixedly mounted with a drive rod 22 via a flange. The electric push rod 20 can push the drive rod 22 to move up and down at the upper end of the stator 60. An airbag 23 is fixedly mounted on the end of the drive rod 22 away from the electric push rod 20. A communicating air tube is fixedly mounted on the airbag 23 and connected to the external... The air supply tube is fixedly connected, allowing for the inflation and deflation of the airbag 23. When the airbag 23 is not inflated, its diameter is smaller than the circular hole in the middle of the PCB board 70. The robotic arm transports the PCB board 70 to the bottom of the drive rod 22. At this time, the electric push rod 20 pushes the drive rod 22 downward, allowing the airbag 23 to be inserted into the circular hole of the PCB board 70. Then, the airbag 23 is inflated, and the airbag 23 expands and fixes the PCB board 70 in place (the amount of gas inflated is pre-set according to the diameter of the circular hole to avoid damaging the PCB board 70).

[0026] The limiting plate 21 is U-shaped, with one end fixed to the outer wall of the electric push rod 20 and the other end located on the outside of the drive rod 22, and is distributed in a circular pattern. The limiting plate 21 is used to limit the position of the wire gripping component.

[0027] In one embodiment, please refer to Figures 5-10 The wire gripping component includes a movable ring 25 and a support ring 28. The movable ring 25 is slidably sleeved on the outside of the drive rod 22. A movable sleeve 251 is fixedly installed at one end of the movable ring 25. When the movable ring 25 slides on the outside of the drive rod 22, the movable sleeve 251 guides it. A spring 26 is fixedly connected to the other end of the movable ring 25. A fixed ring 24 is fixedly installed at the end of the spring 26 away from the movable ring 25. The fixed ring 24 is fixed on the side wall of the drive rod 22. Multiple connecting plates 252 are evenly fixedly installed on the side wall of the movable ring 25. The end of the connecting plate 252 away from the movable ring 25 is fixed to the upper end of the support ring 28. The movable ring 25, the movable sleeve 251, and the support ring 28 can slide on the outside of the drive rod 22 by compressing the spring 26.

[0028] A threaded groove is provided on the outer wall of the drive rod 22. The threaded groove is located at the lower end of the movable sleeve 251. A limit nut 27 is threadedly connected to the outer wall of the drive rod 22 through the threaded groove. The upper end of the limit nut 27 contacts the lower end of the movable sleeve 251 and is used to limit the downward movement of the movable ring 25 and the support ring 28.

[0029] A rotating shaft 29 with corresponding leads and reserved holes is rotatably connected to the support ring 28 via a rotating seat. The multiple rotating shafts 29 can move down with the support ring 28 and can also rotate on the support ring 28. A wire gripping assembly is provided at the lower end of the rotating shaft 29. The size of the wire gripping assembly is smaller than the reserved hole on the PCB board 70, and the wire gripping assembly and the reserved hole correspond one-to-one. When the electric push rod 20 pushes the air bag 23 at the lower end of the drive rod 22 into the round hole on the PCB board 70, the wire gripping assembly is driven to pass through the corresponding reserved hole on the PCB board 70. A drive assembly is provided on one side of the support ring 28. The drive assembly is used to drive the rotating shaft 29 and the wire gripping assembly to rotate. The drive assembly drives the rotating shaft 29 and the wire gripping assembly to rotate 360 ​​degrees each time. The wire gripping assembly rotates at the lower end of the PCB board 70 and grips the lead of the copper coil 61.

[0030] The wire gripping assembly includes a wire gripping plate 291 fixed to the lower end of the rotating shaft 29. The wire gripping plate 291 can pass through a pre-drilled hole. A conductor slope 292 is provided on one side of the lower end of the wire gripping plate 291. The end of the wire gripping plate 291 away from the conductor slope 292 is close to the edge of the pre-drilled hole. An arc-shaped hook plate 293 is fixedly installed on the upper end of the wire gripping plate 291 near the conductor slope 292. A lead plate 294 is fixedly installed on the end of the hook plate 293 away from the wire gripping plate 291. When the wire gripping plate 291 passes through the pre-drilled hole, the lead wire will be located on one side of the wire gripping plate 291 under the action of the conductor slope 292. The wire gripping plate 291 rotates 360 degrees and hooks the lead wire through the hook plate 293.

[0031] A pressure plate 295 is rotatably connected to the upper end of the wire gripping plate 291, away from the conductor slope 292, via a torsion spring 298. The width and length of the pressure plate 295 are greater than the length and width of the hook plate 293. Round shafts 297 are fixedly installed at both ends of the pressure plate 295 near the wire gripping plate 291. An ear block 296 is rotatably connected to the end of the round shaft 297 away from the pressure plate 295. The ear block 296 is fixed to the outer wall of the wire gripping plate 291, and the torsion spring 298 is sleeved on the round shaft 297. One end of the torsion spring 298 is fixedly connected to the pressure plate 295, and the other end is fixedly connected to the ear block 296. When the torsion spring 298 is in a balanced state, the pressure plate 295 and the wire gripping plate... 291 is vertical, and the pressure plate 295 is located on the side of the wire gripping plate 291 near the edge of the reserved hole. When the wire gripping plate 291 passes through the reserved hole, the pressure plate 295 contacts the edge of the reserved hole. The pressure plate 295 rotates on one side of the wire gripping plate 291 through the round shaft 297 and adheres to the outer wall of the wire gripping plate 291 to facilitate passing through the reserved hole. If the lead wire is located outside the hook plate 293, the hook plate 293 does not hook it when it rotates. The end of the wire gripping plate 291 away from the hook plate 293 will contact the lead wire and pull the lead wire to one side of the pressure plate 295. When the wire gripping plate 291 moves upward, the pressure plate 295 adheres to one side of the wire gripping plate 291 and presses the lead wire.

[0032] After the drive assembly drives the wire gripping assembly to rotate 360 ​​degrees, the electric push rod 20 starts again and pushes the drive rod 22 down. At this time, the support ring 28 and the lower side wall of the limit plate 21 contact each other, and the compression spring 26 moves up at the outer end of the drive rod 22 to prevent the rotating shaft 29 and the wire gripping component from moving down. The drive rod 22 pushes the PCB board 70 into the stator 60. At the same time, the wire gripping component carries the lead wire through the reserved hole of the PCB board 70 to complete the wire threading of the PCB board 70. The lead wire can then be soldered to the upper end of the PCB board 70 by external soldering equipment. Then the airbag 23 is deflated, the electric push rod 20 is reset, and the PCB board 70 is installed in the stator 60.

[0033] In one embodiment, please refer to Figures 2-6 The drive assembly includes a motor 30, a gear ring 33, and multiple driven gears 35. The motor 30 is fixed to the outer end of the output shaft of the electric push rod 20. The motor 30 can move synchronously with the output end of the electric push rod 20. A hexagonal prism 31 is fixedly installed on the output shaft of the motor 30. A sleeve 311 is slidably sleeved on the outer end of the hexagonal prism 31. A hexagonal groove corresponding to the hexagonal prism 31 is provided on the inner end of the sleeve 311. The hexagonal prism 31 can slide inside the sleeve 311. A drive gear 32 is fixedly installed on the lower end of the sleeve 311. When the motor 30 starts, it can drive the hexagonal prism 31, the sleeve 311, and the drive gear 32 to rotate synchronously.

[0034] The gear ring 33 is rotatably sleeved on the outer end of the drive rod 22. The upper end of the gear ring 33 is fixedly connected to the outer wall of the second bearing 34 via multiple connecting rods. The inner wall of the second bearing 34 is fixedly sleeved on the output shaft of the electric push rod 20, thereby rotatably sleeved on the outer side of the output shaft of the electric push rod 20. The driven gear 35 is fixed on the upper end of the rotating shaft 29. The outer wall of the driven gear 35 meshes with the outer wall of the gear ring 33. When the gear ring 33 rotates, it can simultaneously drive multiple driven gears 35 to rotate the rotating shaft 29. Furthermore, the outer wall of one of the driven gears 35 is meshed with the outer wall of the driving gear 32, and the outer ends of one of the rotating shafts 29 and the sleeve 311 are fixedly sleeved with the first bearing 312. The outer walls of the two first bearings 312 are fixedly connected by a connecting block. When the support ring 28 moves upward with the rotating shaft 29 and the driven gear 35 through the compression spring 26, the sleeve 311 slides on the hexagonal prism 31 with the driving gear 32, so that the driving gear 32 and one of the driven gears 35 always remain in a meshed connection.

[0035] When the motor 30 starts, it drives the drive gear 32 to rotate. The drive gear 32 drives one of the driven gears 35 to rotate. The driven gear 35 drives the gear ring 33 and several other driven gears 35 to rotate synchronously, thereby driving multiple rotating shafts 29 to rotate 360 ​​degrees with the wire gripping assembly to complete the gripping of the lead wire.

[0036] In one embodiment, please refer to Figure 2 , Figure 4 , Figure 11 and Figure 12 An adjusting component is installed on the upper end of the base plate 10. A positioning seat 40 is fixedly installed on the upper end of the adjusting component. The adjusting component is used to adjust the inner diameter of the positioning seat 40. The adjusting component includes a protective shell 50 fixed on the base plate 10. The upper end of the protective shell 50 has multiple slotted holes 51. The positioning seat 40 is fixed on the upper end of the protective shell 50 and located outside the slotted holes 51. Multiple guide sleeves 55 arranged in a circular pattern are fixedly installed on the outer end of the protective shell 50. A sun gear 52 is rotatably connected to the middle part of the protective shell 50, and multiple planetary gears 53 arranged in a circular pattern are meshed with the outer end of the sun gear 52. Each planetary gear 53 has a fixedly installed upper end. Each pinion 531 has a rack 54 meshing with its outer wall. A guide bar 541 is fixedly installed at one end of the rack 54. The end of the guide bar 541 away from the rack 54 slides through the protective shell 50 and the guide sleeve 55. A support rod 542 is fixedly installed on the upper side of the end of the rack 54 away from the guide bar 541. The upper end of the support rod 542 slides through the strip hole 51 and is fixedly installed with a clamping plate 543. The clamping plate 543 is located inside the positioning seat 40. The clamping plate 543 is an elastic plate. When it contacts the outer wall of the stator 60, the clamping plate 543 deforms and fits against the outer end of the stator 60, which can fix stators 60 of different diameters.

[0037] A drive motor is fixedly installed at the bottom of the protective shell 50. The output shaft of the drive motor is fixed to the drive shaft of the sun gear 52 and is used to drive the sun gear 52 to rotate. When the sun gear 52 rotates, it drives multiple planetary gears 53 to rotate with the pinion 531. The pinion 531 drives the rack 54, support rod 542 and clamping plate 543 to move synchronously, which can clamp the stator 60 placed in the positioning seat 40.

[0038] In one embodiment, please refer to Figure 4 A positioning tip 41 is provided at the outer end of the positioning seat 40. Before the stator 60 is placed into the positioning seat 40, the lead wire of the copper coil 61 inside the stator 60 is trimmed to a uniform length and straightened upward. When the stator 60 is inserted into the positioning seat 40, one of the lead wires is positioned inside the positioning tip 41. Since the position of the PCB board 70 transported by the robot is fixed and the position of the reserved hole on it corresponds to the positioning tip 41, the reserved hole on the PCB board 70 can correspond to the position of the lead wire.

[0039] When this device is in operation, the lead wire of the copper coil 61 in the stator 60 is placed into the positioning seat 40 with the positioning tip 41 aligned with it, and the stator 60 is fixed in place by the adjusting component. Then, the external robotic arm transports the PCB board 70 to the lower end of the drive component. The electric push rod 20 is activated to push the air bag 23 at the lower end of the drive rod 22 into the round hole on the PCB board 70, and the air bag 23 is inflated. At the same time, the wire gripping assembly passes through the corresponding reserved hole on the PCB board 70. Then, the drive component drives the wire gripping assembly to rotate 360 ​​degrees to complete the wire gripping. Then, the electric push rod 20 is activated again and pushes... The drive rod 22 moves down again. At this time, the support ring 28 and the lower side wall of the limit plate 21 come into contact. The compression spring 26 moves up at the outer end of the drive rod 22, preventing the rotating shaft 29 and the wire gripping component from moving down. The drive rod 22 pushes the PCB board 70 into the stator 60. At the same time, the wire gripping component carries the lead wire through the reserved hole of the PCB board 70, completing the wire threading of the PCB board 70. The lead wire can then be soldered to the upper end of the PCB board 70 by external soldering equipment. Finally, the airbag 23 is deflated, and the electric push rod 20 is reset, completing the wire threading of the PCB board 70 and its installation in the stator 60.
