Description

Technical Field

[0001] This invention relates to the field of automated motor assembly equipment, and in particular to a core assembly equipment and method. Background Technology

[0002] In the assembly process of a motor, the iron core needs to be wound. During winding, the iron core is placed on a jig. After winding, the iron core needs to be detached from the jig. A reversing mechanism is used to reverse the direction of the iron core so that the side facing outwards is aligned with the end of the core. A transport mechanism is used to transport the iron core to a core assembly stand for assembly. Twelve cores are assembled to form a circular stator. The stator's cross-connect wires are then arranged to facilitate subsequent stator assembly. Finally, the stator is removed from the core assembly stand and discharged. Existing core assembly equipment is typically complex in structure, occupies a large area, and is inconvenient to operate. Furthermore, existing technologies for core assembly lines suffer from poor accuracy due to inaccurate core positioning. Therefore, there is an urgent need to develop a core assembly equipment and method to meet practical needs. Summary of the Invention

[0044] The present invention is as follows Figures 1 to 17As shown, a core rounding device includes a frame 10, a demolding and tidying mechanism 20 for demolding the core and tidying the tail wire of the core, a conveying mechanism 30 for transporting the core, a reversing mechanism 40 for changing the direction of the core to facilitate rounding, a rounding and tidying mechanism 50 for rounding the core and tidying the tail wire, a pushing mechanism 60 for pushing the bridge wire of the core, a lifting and pushing mechanism 70 for lifting and pulling out the rounded core, and a discharging mechanism 80 for discharging the core, wherein:

[0045] The frame 10 is equipped with a workbench 11 for installing a demolding and assembling mechanism 20, a conveying mechanism 30, a reversing mechanism 40, a rounding and arranging mechanism 50, a bridging line pushing mechanism 60, a lifting and material-discharging mechanism 70, and a discharging mechanism 80. The conveying mechanism 30 is located between the demolding and assembling mechanism 20, the reversing mechanism 40, and the rounding and arranging mechanism 50. The bridging line pushing mechanism 60 and the lifting and material-discharging mechanism 70 are distributed on the side of the rounding and arranging mechanism 50. The discharging mechanism 80 corresponds to the lifting and material-discharging mechanism 70.

[0046] By employing a demolding and assembly mechanism 20, a handling mechanism 30, a reversing mechanism 40, a rounding and wire management mechanism 50, a bridge wire pushing mechanism 60, a lifting and material feeding mechanism 70, and a discharge mechanism 80, the demolding, handling, reversing, rounding and wire management, bridge wire pushing, lifting and material feeding of iron cores are automated, thereby improving work efficiency.

[0047] The demolding and assembling mechanism 20 includes a demolding assembly 21 for demolding the iron core, a transfer drive assembly 22 for moving the demolded iron core, and an assembling assembly 23 for pressing the tail wire of the iron core inward. The transfer drive assembly 22 is located between the demolding assembly 21 and the assembling assembly 23. The demolding assembly 21 has a jig seat 214 for placing the iron core. The transfer drive assembly 22 has a sliding material seat 222 for moving the iron core. The assembling assembly 23 has a pressing block 2342 for pressing the tail wire of the iron core inward. The jig seat 214 can be lowered to detach from the iron core. The sliding material seat 222 is movable and corresponds to the iron core on the jig seat 214. The pressing block 2342 is movable and abuts against the tail wire of the iron core on the sliding material seat 222.

[0048] The iron core is vertically inserted into the jig seat 214. The jig seat 214 of the demolding assembly 21 descends, and the iron core detaches from the jig seat 214 and falls onto the sliding material seat 222. The sliding material seat 222 drives the iron core to move to the side of the line assembly 23. The clamping block 2342 of the line assembly 23 moves to the side of the sliding material seat 222, and the clamping block 2342 clamps the tail wire of the iron core inward.

[0049] The demolding, transfer, and assembly of the iron core are automated by using demolding component 21, transfer drive component 22, and assembly component 23. The overall structure is compact, occupies little area, is simple to operate, and has high assembly accuracy.

[0050] The demolding assembly 21 also includes a support 211, a lifting drive device 212, a clamping drive device 213, and a mounting base 2134. The lifting drive device 212 is mounted on the support 211. The clamping drive device 213 and the mounting base 2134 are both mounted on the output end of the lifting drive device 212. The fixture base 214 is disposed on the mounting base 2134, and the clamping end of the clamping drive device 213 corresponds to the fixture base 214.

[0051] The clamping drive device 213 includes a transverse drive cylinder 2131, a first clamping block 2132, and a second clamping block 2133. The transverse drive cylinder 2131 is installed at the output end of the lifting drive device 212. The first clamping block 2132 is installed at the shaft end of the transverse drive cylinder 2131. The second clamping block 2133 is fastened to the output end of the lifting drive device 212. The second clamping block 2133 abuts against the right side of the fixture seat 214, and the first clamping block 2132 is movable and abuts against the left side of the fixture seat 214.

[0052] The lifting drive device 212 includes a lifting drive cylinder 2121 and a lifting slide 2122. The lifting drive cylinder 2121 is installed below the support 211, and the lifting slide 2122 is installed on the shaft end of the lifting drive cylinder 2121. The clamping drive device 213 and the mounting base 2134 are both installed on the lifting slide 2122.

[0053] Specifically, the jig seat 214 is detachably mounted on the mounting base 2134, the second clamping block 2133 abuts against the right side of the jig seat 214, the lateral drive cylinder 2131 drives the first clamping block 2132 to move laterally, the first clamping block 2132 moves laterally to the right to clamp the jig seat 214, and the first clamping block 2132 moves laterally to the left to put the jig seat 214 in a free state; the lifting drive cylinder 2121 drives the lifting slide 2122 to descend, and the clamping drive device 213 descends with the lifting slide 2122, pulling down the jig seat 214 so that the iron core is detached from the jig seat 214.

[0054] The clamping drive device 213 is used to clamp the fixture seat 214, and the lifting drive device 212 is used to pull down the fixture seat 214, so that the iron core is separated from the fixture seat 214, which facilitates the subsequent rounding operation of the iron core; the overall structure is compact and the operation is simple.

[0055] The transfer drive assembly 22 also includes a longitudinal drive motor 221 and a lead screw. The longitudinal drive motor 221 is mounted on the support frame 231, and the lead screw is mounted on the shaft end of the longitudinal drive motor 221. The lead screw is rotatably engaged with the aforementioned sliding material seat 222.

[0056] The sliding material holder 222 has an opening for the jig holder 214 to pass through. The jig holder 214 descends relative to the sliding material holder 222, while the iron core is on the sliding material holder 222. The longitudinal drive motor 221 drives the lead screw to rotate, and the rotation of the lead screw causes the sliding material holder 222 to move. The iron core moves with the sliding material holder 222 to the side of the line assembly 23. The use of the longitudinal drive motor 221 and the lead screw to provide driving force improves the accuracy and balance of position movement.

[0057] The assembly line 23 includes a support frame 231, a vertical drive device 232, a limit drive device 233, and a clamping drive device 234. The vertical drive device 232 is vertically mounted on the support frame 231, and the limit drive device 233 and the clamping drive device 234 are both mounted on the output end of the vertical drive device 232.

[0058] The limit drive device 233 limits the iron core; the clamping drive device 234 clamps the tail wire of the iron core; the vertical drive device 232 drives the limit drive device 233 and the clamping drive device 234 to rise and fall; the limit drive device 233 prevents the iron core from shifting position during the whole line process, thus improving the accuracy of the whole line; the clamping drive device 234 realizes the tidying of the tail wire of the iron core; the vertical drive device 232 meets the position movement requirements during the whole line process.

[0059] The vertical drive device 232 includes a vertical drive cylinder 2321 and a vertical slide block 2322. The vertical drive cylinder 2321 is mounted on the support frame 231, and the vertical slide block 2322 is mounted on the shaft end of the vertical drive cylinder 2321.

[0060] There are two vertical drive cylinders 2321, which are distributed at both ends of the vertical slide block 2322. The use of two vertical drive cylinders 2321 improves the balance and stability of the vertical slide block 2322 during lifting and lowering.

[0061] The limiting drive device 233 includes a limiting drive cylinder 2331 and a limiting block 2332. The limiting drive cylinder 2331 is longitudinally mounted on a vertical slide block 2322, and the limiting block 2332 is mounted on the shaft end of the limiting drive cylinder 2331.

[0062] The clamping drive device 234 includes a clamping drive cylinder 2341 and the aforementioned clamping block 2342. The clamping drive cylinder 2341 is mounted on a vertical slide block 2322, and the clamping block 2342 is mounted on the shaft end of the clamping drive cylinder 2341. The limiting block 2332 can move to limit the tail wire of the iron core, and the clamping block 2342 can move to clamp the tail wire of the iron core inward.

[0063] The front end of the clamping block 2342 is provided with a wire receiving groove for accommodating the iron core tail wire, and the two sides of the wire receiving groove are in the shape of "V" to facilitate the guidance of the iron core tail wire.

[0064] Specifically, the vertical drive cylinder 2321 drives the vertical slide block 2322 to rise and fall, so that the limit drive device 233 and the clamping drive device 234 correspond to the tail wire of the iron core. The limit drive cylinder 2331 drives the limit block 2332 to limit the iron core, and the clamping drive cylinder 2341 drives the clamping block 2342 to move and clamp the tail wire of the iron core inward. The two sides of the wire receiving groove are "V" shaped, which facilitates the guidance of the tail wire of the iron core, so that the tail wire of the iron core is located in the wire receiving groove, making the clamping position more accurate and improving the accuracy of the whole line.

[0065] The conveying mechanism 30 includes a conveying bracket 31, a horizontal conveying drive assembly 32, a vertical conveying drive assembly 33, a first vertical conveying drive assembly 34, a first clamping cylinder 35, a second vertical conveying drive assembly 36, a rotary drive motor 37, and a second clamping cylinder 38. The horizontal conveying drive assembly 32 is mounted on the conveying bracket 31, the vertical conveying drive assembly 33 is mounted at the output end of the horizontal conveying drive assembly 32, the first vertical conveying drive assembly 34 and the second vertical conveying drive assembly 36 are mounted opposite each other at the output end of the vertical conveying drive assembly 33, the first clamping cylinder 35 is mounted at the output end of the first vertical conveying drive assembly 34, the rotary drive motor 37 is mounted at the output end of the second vertical conveying drive assembly 36, and the second clamping cylinder 38 is mounted on the shaft end of the rotary drive motor 37.

[0066] The transverse transport drive assembly 32, the longitudinal transport drive assembly 33, the first vertical transport drive assembly 34, and the second vertical transport drive assembly 36 all include a motor, a lead screw, and a slide. The lead screw is mounted on the shaft end of the motor and rotates with the slide, which serves as the output end. The use of a motor and lead screw increases the driving force and improves the accuracy of position movement.

[0067] The first clamping cylinder 35 clamps the four iron cores on the demolding and assembly line mechanism 20, and moves them to the reversing mechanism 40 under the drive of the horizontal transport drive component 32, the vertical transport drive component 33, and the first vertical transport drive component 34. After the reversing is completed, the second clamping cylinder 38 clamps the four iron cores on the reversing mechanism 40, and moves them to the rounding and assembling mechanism 50 under the drive of the horizontal transport drive component 32, the vertical transport drive component 33, the second vertical transport drive component 36, and the rotary drive motor 37. The second clamping cylinder 38 transports the iron cores three times in total, transporting four iron cores each time, and transporting the 12 iron cores to the rounding material seat for rounding.

[0068] The reversing mechanism 40 includes a reversing drive assembly 41 for reversing the iron core, a limiting drive assembly 42 for limiting the iron core, and a pressing drive assembly 43 for pressing the bridge wire of the iron core inward. The limiting drive assembly 42 is located beside the reversing drive assembly 41. The pressing drive assembly 43 corresponds to the bridge wire of the iron core. The reversing drive assembly 41 has a rotating device 415, which includes a rotating shaft 4151, a first feeding seat 4152 for placing the iron core, and a second feeding seat 4153. The first feeding seat 4152 is connected to the rotating shaft 4151. The second feeding seat 4153 is connected to the first feeding seat 4152. The rotation of the rotating shaft 4151 drives the first feeding seat 4152 to rotate, and the rotation of the first feeding seat 4152 drives the second feeding seat 4153 to rotate.

[0069] The stator is formed by piecing together twelve iron cores. Before piecing them together, the iron cores need to be rotated so that the large arc side of the iron core is rotated from facing inward to facing outward, which facilitates the subsequent piecing together operation.

[0070] Iron cores are placed on both the first feeding seat 4152 and the second feeding seat 4153. The rotation of the rotating shaft 4151 drives the first feeding seat 4152 to rotate, and the second feeding seat 4153 rotates synchronously with the first feeding seat 4152. The large arc side of the iron core on the first feeding seat 4152 and the second feeding seat 4153 changes from being placed inward to being placed outward, which facilitates the rounding of the iron core. After the iron core is reversed, the limit drive component 42 presses against the iron core to limit the iron core. The line abutment drive component 43 presses the bridge wire of the iron core inward to prevent the position of the bridge wire from interfering with the rounding of the iron core.

[0071] The system employs a reversing drive assembly 41, a limit drive assembly 42, and a contact drive assembly 43 to automatically change the direction of the iron core, limit its position, and tighten the cross-bracing wire, thereby improving work efficiency and reducing labor costs. The reversing drive assembly 41 reverses the direction of the large arc side of the iron core outward, facilitating subsequent iron core assembly. The limit drive assembly 42 limits the iron core to prevent positional deviation and improves the accuracy of contacting the wire. The contact drive assembly 43 tightens the cross-bracing wire inward, preventing positional interference of the cross-bracing wire during iron core assembly. The overall structure is compact and occupies little space.

[0072] The reversing drive assembly 41 also includes a reversing support 411, a lateral drive cylinder 413, and a rotary drive device 414. The lateral drive cylinder 413 is mounted laterally on the reversing support 411, and the rotary drive device 414 is mounted on the output end of the lateral drive cylinder 413. The aforementioned rotating shaft 4151 is connected to the output end of the rotary drive device 414.

[0073] The rotary drive device 414 includes a rack 4141 and a gear 4142. The rack 4141 is mounted on the output end of the transverse drive cylinder 413. The gear 4142 meshes with the rack 4141 and is fastened to the rotating shaft 4151. The transverse drive cylinder 413 drives the rack 4141 to move, and the movement of the rack 4141 drives the gear 4142 to rotate. The rotating shaft 4151 rotates with the gear 4142.

[0074] The transverse drive cylinder 413 moves laterally, driving the rack 4141 to move laterally. The transverse movement of the rack 4141 drives the gear 4142 to rotate. The rotating shaft 4151 rotates with the gear 4142. The first feeding seat 4152 rotates with the rotating shaft 4151. The first feeding seat 4152 is connected to the second feeding seat 4153. The second feeding seat 4153 rotates with the first feeding seat 4152. The iron cores on the first feeding seat 4152 and the second feeding seat 4153 rotate synchronously.

[0075] The rotation of the rotating shaft 4151 is achieved by using a transverse drive cylinder 413 and a rotary drive device 414, resulting in high rotation accuracy.

[0076] The rotating device 415 also includes a connecting arm 4154, with the first feeding seat 4152 and the second feeding seat 4153 symmetrically arranged at both ends of the connecting arm 4154. The rotation of the first feeding seat 4152 drives the connecting arm 4154 to move, and the movement of the connecting arm 4154 drives the second feeding seat 4153 to rotate. The connecting arm 4154 enables the first feeding seat 4152 and the second feeding seat 4153 to rotate synchronously, eliminating the need for other drives to achieve the rotation of the second feeding seat 4153, reducing production costs, and ensuring high rotation consistency.

[0077] The upper surface of the reversing support 411 is provided with a mounting block 412. The first feeding seat 4152 is rotatably located at one end of the mounting block 412, and the second feeding seat 4153 is rotatably located at the other end of the mounting block 412.

[0078] There are two sets of mounting blocks 412, rotary drive devices 414, and rotating devices 415. The two sets of mounting blocks 412 are symmetrically arranged on the reversing support 411. The two sets of rotary drive devices 414 are symmetrically mounted on the output end of the transverse drive cylinder 413. The two sets of rotating devices 415 are correspondingly arranged on the two sets of mounting blocks 412. The two sets of rotating devices 415 are correspondingly connected to the output end of the two sets of rotary drive devices 414.

[0079] A transverse drive cylinder 413 drives two sets of rotary drive devices 414, thereby realizing the rotation of two sets of rotating devices 415, satisfying the synchronous rotation of two sets of first feeding seats 4152 and two sets of second feeding seats 4153. That is, a transverse drive cylinder 413 is used to realize the synchronous rotation of four iron cores, with high consistency of rotation position, improving work efficiency and reducing production costs.

The limit cylinder 421 is horizontally mounted on the upper surface of the reversing support 411, and the limit slider 422 is mounted on the shaft end of the limit cylinder 421 and corresponds to the iron core. There are two sets of limit drive assemblies 42, which are distributed opposite to each other. The limit cylinder 421 drives the limit slider 422 to move, and the limit slider 422 presses against the iron core to prevent the iron core from shifting position.

[0081] The abutment drive assembly 43 includes an abutment bracket 431, an abutment cylinder 432, and an abutment block 433. The abutment cylinder 432 is longitudinally mounted on the abutment bracket 431, and the abutment block 433 is mounted on the shaft end of the abutment cylinder 432. The abutment block 433 is movable and abuts against the bridging wire of the iron core. There are two sets of abutment drive assemblies 43, which are distributed opposite to each other. The abutment cylinder 432 drives the abutment block 433 to move and press the bridging wire of the iron core inward to prevent the bridging wire of the iron core from interfering with the position of the bridging wire when the iron core is assembled.

[0082] The rounding and thread-arranging mechanism 50 includes a support base 51, a turntable assembly, and a thread-arranging assembly. The turntable assembly includes a rotary motor 521, a rotating disk 522, and a rounding material holder 523. The rotary motor 521 is mounted on the support base 51, the rotating disk 522 is rotatably located on the support base 51, the rotating disk 522 is mounted on the shaft end of the rotary motor 521, and the rounding material holder 523 is mounted on the rotating disk 522.

[0083] The iron cores are transported to the rounding material holder 523 for rounding; the rotary motor 521 drives the rotating disk 522 to rotate, and the rotating disk 522 drives the rounding material holder 523 to move; the rounding material holder 523 moves to the side of the wire management component, and the wire management component tidies up the tail wire of the iron core to avoid positional interference during rounding. After the twelve iron cores are rounded on the rounding material holder 523, a circular stator is formed; the bridge wire pushing mechanism 60 pushes the bridge wire of the iron core outward; the lifting and material pulling mechanism 70 pulls the circular stator out from the rounding and wire management mechanism 50.

[0084] By employing a wire-reaming and assembling mechanism 50, a bridge wire pushing mechanism 60, and a lifting and material-moving mechanism 70, the iron core's wire-reaming, bridge wire pushing, and lifting and material-moving processes are automated, reducing labor costs. The overall structure is compact and occupies little space.

[0085] The cable management assembly includes a mounting plate 531, a horizontal cable management device 532 and a vertical cable management device 533 distributed on the mounting plate 531. Both the horizontal cable management device 532 and the vertical cable management device 533 include a cable management drive cylinder 5331 and a hook 5332, with the hook 5332 mounted on the shaft end of the cable management drive cylinder 5331. There are two sets of horizontal cable management devices 532, which are distributed laterally opposite to each other. There are also two sets of vertical cable management devices 533, which are distributed longitudinally opposite to each other. The use of two sets of horizontal cable management devices 532 and two sets of vertical cable management devices 533 improves the balance of cable management.

[0086] The iron cores are transported by the conveying mechanism 30 to the rounding material holder 523. The conveying mechanism 30 transports four iron cores at a time, and transports them in three batches, for a total of twelve iron cores, to the rounding material holder 523 for rounding. The rotary motor 521 drives the rotating disk 522 to rotate, and the rotation of the rotating disk 522 drives the rounding material holder 523 to move. The rounding material holder 523 moves to the side of the wire management assembly. After the first transport of iron cores to the rounding material holder 523, the wire management drive cylinder 5331 of the transverse wire management device 532 drives the hook 5332 to hook the tail wire of the four transported iron cores, which facilitates the second transport of iron cores and avoids positional interference. After the second transport of four iron cores, the wire management drive cylinder 5331 of the longitudinal wire management device 533 drives the hook 5332 to hook the tail wire of the four transported iron cores, which facilitates the third transport of iron cores and avoids positional interference. After the twelve iron cores are rounded on the rounding material holder 523, a circular stator is formed.

[0091] Specifically, the push-drive cylinder 611 drives the push-drive shaft 612 to move upward, and the push-drive shaft 612 moves to the center position of the stator. The push-drive shaft 612 pushes the stator's bridge line upward. The vertical movement drive cylinder drives the vertical movement slide to descend, and the clamping device descends with the vertical movement slide. The abutting block 642 descends to the top of the stator, and the abutting drive cylinder 641 drives the abutting block 642 to descend. The abutting block 642 pushes the stator's bridge line outward. The pressing drive cylinder 651 drives the pressing block 652 to descend, and the pressing block 652 presses the edge of the bridge line to limit the bridge line.

[0092] The stator bridge line is pushed by a pusher bracket 62, a vertical drive device 63, abutting device 64 and a clamping device 65, which moves the bridge line facing inward to the outward, thus meeting the requirements for moving the bridge line position; the overall structure is compact and occupies little space.

[0093] The lifting and material-pulling mechanism 70 includes a wire-stopping drive cylinder 71 for bringing the iron core tail wire inward, a clamping and limiting device 72, and a lifting and material-pulling device 73.

The clamping and limiting device 72 includes a clamping and limiting drive cylinder 721 and a pressure plate 722, which is mounted on the shaft end of the clamping and limiting drive cylinder 721.

[0094] The lifting and feeding device 73 includes a lifting cylinder 731 and a lifting block 732. The lifting block 732 is installed on the shaft end of the lifting cylinder 731 and is located on the lower surface of the iron core.

[0095] The guide cylinder 71 moves the iron core tail wire inward to facilitate stator material feeding. The clamping and limiting guide cylinder 721 drives the pressure plate 722 to descend and clamp the upper surface of the stator. The lifting cylinder 731 drives the lifting block 732 to rise and press against the lower surface of the stator. The driving force of the lifting cylinder 731 is greater than the driving force of the clamping and limiting guide cylinder 721. The rise of the lifting block 732 drives the stator and the pressure plate 722 to rise synchronously, thus pulling the stator away from the rounding material seat 523. The clamping and limiting device 72 is used to clamp the upper surface of the stator, prevent the position of the stator from shifting during movement, and improve the material feeding accuracy.

[0096] The discharge mechanism 80 includes a robotic arm 81 and a clamping cylinder 82. The clamping cylinder 82 is installed at the front end of the robotic arm 81.

[0097] The method for rounding iron cores using this equipment includes the following steps:

[0098] First, the demolding and finishing mechanism demolds the iron core and tidies up the tail wire of the iron core;

[0099] Second, the conveying mechanism moves the iron core on the demolding assembly line mechanism to the reversing mechanism;

[0100] Third, the reversing mechanism changes the direction of the iron core, so that the large arc side of the iron core changes from facing inward to facing outward;

[0101] Fourth, the transport mechanism moves the iron core from the reversing mechanism to the rounding and wire-arranging mechanism;

[0102] Fifth, the wire-aligning mechanism aligns the iron core into a circle and tidies up the tail wire of the iron core during the alignment process;

[0103] Sixth, the wire-aligning mechanism moves the iron core to below the bridge wire pushing mechanism, which pushes the bridge wire of the iron core outward.

[0104] Seventh, the wire-reaming mechanism moves the iron core to the side of the lifting and material-pushing mechanism, which then pulls the iron core out of the wire-reaming mechanism.

[0105] Eighth, the discharge mechanism discharges the extracted iron core.

[0106] The key design feature of this invention is that by employing a demolding and assembly mechanism, a transport mechanism, a reversing mechanism, a rounding and wire-arranging mechanism, a bridge wire pushing mechanism, a lifting and material-discharging mechanism, and a discharge mechanism, the demolding, transporting, reversing, rounding and wire-arranging, bridge wire pushing, lifting and material-discharging, and discharge of the iron core are automated, thus improving work efficiency. The demolding assembly, transfer drive assembly, and assembly assembly are used to automate the demolding, transfer, and assembly of the iron core, resulting in a compact overall structure, small footprint, simple operation, and high assembly accuracy. The reversing drive assembly, limit drive assembly, and line-blocking drive assembly are used to automate the conversion of the iron core's direction, limit the iron core's position, and tighten the iron core's bridge wire, reducing labor costs.
