Description

Technical Field

[0001] This invention relates to the field of automated motor assembly equipment, and in particular to a device and a winding method for winding winding pole blocks. Background Technology

[0002] The motor consists of a rotor and a stator. The stator has multiple winding pole blocks. When winding the stator, the winding pole blocks need to be wound sequentially. Before winding, the wire is hung in the first hanging position in the fixture to fix the movable wire. After the winding pole blocks are wound, the wire is hung in the second hanging position in the fixture. Then the wire between the first hanging position and the winding pole block is cut. Finally, the wires on both sides of the second hanging position are cut.

[0003] Existing winding machines suffer from technical problems such as low winding efficiency, inconsistent winding tightness, and low wire cutting accuracy. At the same time, most existing winding machines cannot fully automate stator winding, resulting in high labor costs. Therefore, there is an urgent need to develop a device and method for winding pole blocks to meet practical needs. Summary of the Invention

[0044] The frame 10 is provided with a workbench 11 for installing the above-mentioned mechanisms; the stator opening and closing moving mechanism 40 includes a fixture assembly 42 for placing the stator and opening and closing the stator; the fixture assembly 42 has a fixture seat 421 for placing the stator and a pressure plate 424 for pressing or releasing the stator, the pressure plate 424 being elastically separable and abutting against the upper side wall of the fixture seat 421; the feeding and discharging mechanism 30 is located between the conveying mechanism 20 and the fixture assembly; the fixture assembly 42 is movably corresponding to the wire pulling mechanism 50 and the wire cutting mechanism 60; the wire cutting mechanism 60 is located beside the wire pulling mechanism 50.

[0045] By employing a conveying mechanism 20, a feeding and discharging mechanism 30, a stator opening and closing moving mechanism 40, a wire drawing mechanism 50, and a wire cutting mechanism 60, the conveying, feeding and discharging, moving, winding, and cutting of the stator are automated, improving work efficiency, reducing production costs, improving winding accuracy, and reducing the defect rate.

[0046] The conveying mechanism 20 includes a conveying component 21, a lifting component, and a fixing component 22. The conveying component 21 has a movable tray. The lifting component is located below the tray. The fixing component 22 has a movable clamping slide plate 222. The tray moves laterally and abuts against the upper end of the lifting component. The lifting component drives the tray to rise. The clamping slide plate 222 of the fixing component 22 clamps the tray.

[0047] The transmission assembly 21 also includes a motor and a transmission belt, the motor driving the pallet to move via the transmission belt; the lifting assembly includes a lifting drive cylinder and a lifting slide plate, the pallet being movably located on the upper surface of the lifting slide; the fixing assembly 22 also includes a clamping drive cylinder 221, the clamping slide plate being mounted on the shaft end of the clamping drive cylinder 221, there are two clamping drive cylinders 221 and two clamping slide plates, distributed on both sides of the pallet, the clamping slide plate 222 clamps the pallet, so that the feeding and discharging mechanism can transfer the stator on the pallet; by using the lifting assembly to lift the pallet and the fixing assembly 22 to fasten the pallet, it is convenient to pick up and put down materials on the pallet, improving the accuracy of picking up and putting down materials.

[0048] The feeding and discharging mechanism 30 includes a bracket 31, a feeding clamping assembly 32 for clamping the unwound stator, a discharging clamping assembly 33 for clamping the wound stator, a lifting drive assembly 34 for driving the feeding clamping assembly 32 and the discharging clamping assembly 33 to move up and down, and a longitudinal drive assembly 35 for driving the lifting drive assembly 34 to move longitudinally. The longitudinal drive assembly 35 is mounted longitudinally on the bracket 31. The lifting drive assembly 34 is mounted vertically at the output end of the longitudinal drive assembly 35. The feeding clamping assembly 32 and the discharging clamping assembly 33 are arranged side by side at the output end of the lifting drive assembly 34. Both the feeding clamping assembly 32 and the discharging clamping assembly 33 include an inner support claw device 331 for supporting the inner wall of the stator and an outer protective ring device 332 for fixing the outer wall of the stator. The outer protective ring device 332 can be lifted and looped around the outer side of the inner support claw device 331.

[0049] The outer protective ring device 332 descends to protect the outer wall of the stator, the inner support gripper device 331 penetrates into the inner wall of the stator to support and fix the stator, the feeding clamping assembly 32 clamps the unwound stator, the lifting drive assembly 34 and the longitudinal drive assembly 35 drive the feeding clamping assembly 32 and the discharging clamping assembly 33 to move synchronously up and down and longitudinally, transferring the unwound stator to the stator opening and closing moving mechanism 40, the feeding clamping assembly 33 clamps the wound stator, the lifting drive assembly 34 and the longitudinal drive assembly 35 drive the feeding clamping assembly 32 and the discharging clamping assembly 33 to move synchronously up and down and longitudinally. The stator, after winding, is transferred to its initial position for discharge. By employing a feeding clamping assembly 32, a discharging clamping assembly 33, a lifting drive assembly 34, and a longitudinal drive assembly 35, the stator's clamping, feeding, discharging, lifting, and longitudinal movement are automated, improving the stability and safety of the stator clamping and fixing, reducing the stator damage rate, and improving the accuracy of stator position movement. The outer protective ring device 332 encircles the outer wall of the stator, and the inner support claw device 331 penetrates into the inner wall of the stator to support and fix it, improving the accuracy and stability of clamping.

[0050] The outer protective ring device 332 includes a protective collar 3321 and a vertical rod 3322. The vertical rod 3322 is mounted in a liftable manner on the output end of the lifting drive assembly 34. The lower end of the vertical rod 3322 is fastened to the protective collar 3321, which is located in a liftable manner outside the inner support gripper device 331. The protective collar 3321 is sleeved on the outer wall of the stator, which limits the stator on the one hand and protects the stator on the other. The protective collar 3321 moves up and down with the vertical rod 3322 at the output end of the lifting drive assembly 34, satisfying the positional requirements for clamping and fixing the stator.

[0051] There are three vertical rods 3322, which are evenly distributed above the protective collar 3321. A transverse connecting rod 3323 is fastened to the upper end of two of the vertical rods 3322. The use of three vertical rods 3322 improves the stability and balance of the stator during position movement and prevents the stator from shifting or tipping over. The transverse connecting rod 3323 further ensures the consistency of the three vertical rods 3322 during the lifting process and prevents the stator from shifting.

[0052] The output end of the lifting drive assembly 34 is vertically fastened with a sleeve 343 for guiding purposes. The vertical rod 3322 is slidably positioned within the sleeve 343. A spring is provided between the lower end of the sleeve 343 and the lower end of the vertical rod 3322. The sleeve 343 guides the vertical rod 3322, ensuring the accuracy of its vertical movement and preventing the stator position from shifting due to tilting. The spring acts as a buffer to prevent rigid collisions.

[0053] The inner support gripper device 331 is an inner support gripper cylinder. The lower end of the outer side wall of the gripper of the inner support gripper cylinder is provided with a groove for anti-slip. The inner side wall of the stator is inserted into the groove, which prevents the stator from slipping during the movement process and further ensures the firmness of the stator clamping.

[0054] The lifting drive assembly 34 includes a lifting drive motor 341, a lifting lead screw, and a lifting slide 342. The lifting drive motor 341 is vertically mounted on the output end of the longitudinal drive assembly 35, and the lifting lead screw is mounted on the shaft end of the lifting drive motor 341. The lifting slide 342 and the lifting lead screw are rotatably engaged. The aforementioned feeding clamping assembly 32 and discharging clamping assembly 33 are arranged side by side on the lifting slide 342. The lifting drive motor 341 drives the lifting slide 342 to rise and fall, and the feeding clamping assembly 32 and the discharging clamping assembly 33 rise and fall synchronously with the lifting slide 342. In the case of stator feeding, it can also discharge the stator after winding, which improves the utilization rate of the equipment and reduces the production cost.

[0055] The longitudinal drive assembly 35 includes a longitudinal drive motor 351, a longitudinal lead screw, and a longitudinal slide. The longitudinal drive motor 351 is longitudinally mounted on the bracket 31, and the longitudinal lead screw is mounted on the shaft end of the longitudinal drive motor 351. The longitudinal slide and the longitudinal lead screw are rotatably engaged, and the longitudinal slide is mounted on the sliding bracket 31. The use of the longitudinal drive motor 351 and the longitudinal lead screw improves the stability and accuracy of the position movement. The longitudinal drive assembly 35 drives the longitudinal slide to move longitudinally, and the lifting drive assembly 34 moves longitudinally with the longitudinal slide, thus meeting the position requirements of the stator movement.

[0056] The longitudinal slide includes a sliding part 3521 located in the middle and two mounting parts 3522 located on both sides of the bracket 31; there are two lifting drive components 34, which are respectively mounted on the two mounting parts 3522; each of the two lifting drive components 34 is equipped with a feeding clamping component 32 and a discharging clamping component 33. The two feeding clamping components 32 and the two discharging clamping components 33 move synchronously with the longitudinal slide, which improves working efficiency, has a compact overall structure, and reduces the floor space.

[0057] The stator opening and closing moving mechanism 40 also includes a support frame 41, an opening and closing drive assembly 43 for driving the jig assembly 42 to fix or loosen the stator, a rotary drive device 44 for driving the stator to rotate, and a longitudinal drive assembly 45 for driving the stator to move longitudinally. The jig assembly 42 also includes a locking protrusion 425 for preventing the pressure plate 424 from shifting position. The opening and closing drive assembly 43 is detachably abutted against the lower side of the pressure plate 424. The locking protrusion 425 is longitudinally movable and abuts against the lower plane of the pressure plate 424. The jig seat 421 is mounted on the output end of the rotary drive device 44. The rotary drive device 44 is mounted on the output end of the longitudinal drive assembly 45.

[0058] The opening and closing drive assembly 43 drives the upper end of the pressure plate 424 of the jig assembly 42 to rotate upward and separate from the jig seat 421. The unwound stator is placed on the jig assembly 42, and the pressure plate 424 of the jig assembly 42 presses down to fix the stator. The longitudinal drive assembly 45 drives the stator to move longitudinally to below the winding mechanism 50. The rotary drive device 44 drives the stator to rotate left and right. The winding mechanism 50 winds the winding pole blocks of the stator. After winding is completed, the longitudinal drive assembly 45 drives the stator to move longitudinally to the side of the feeding and discharging mechanism. The opening and closing drive assembly 43 drives the pressure plate 424 of the jig assembly 42 to lift and release the stator. The feeding and discharging mechanism clamps the wound stator on the jig assembly 42 and places it on the conveying mechanism for discharge. The rotary drive device 44 is a rotary motor. The jig assembly 42's pressure plate 424... The fixture 421 is mounted on the shaft end of the rotary motor. By employing the fixture assembly 42, the opening and closing drive assembly 43, the rotary drive device 44, and the longitudinal drive assembly 45, the opening, closing, rotation, and longitudinal movement of the stator are automatically realized, meeting the requirements for stator rotation and position movement, improving work efficiency, and reducing labor costs. The fixture assembly 42 presses the stator firmly during the rotation and movement of the stator, preventing the stator from shifting position and improving the accuracy of movement. The opening and closing drive assembly 43 drives the upper end of the pressure plate 424 of the fixture assembly 42 to rotate upward to release the stator, meeting the requirements for stator material handling. The design is unique and ingenious, and highly practical. The locking protrusion 425 abuts against the lower side of the pressure plate 424, while the upper side of the pressure plate 424 presses the stator tightly, preventing the stator from deviating during movement.

[0059] The opening and closing drive assembly 43 includes a support 431, a longitudinal drive cylinder 432, a longitudinal slide block 433, and a retaining block 434. The longitudinal drive cylinder 432 is longitudinally mounted on the support 431. The longitudinal slide block 433 is mounted on the shaft end of the longitudinal drive cylinder 432. The retaining block 434 is fastened to the longitudinal slide block 433. The front end of the retaining block 434 has a bevel 435. The bevel 435 abuts against the lower side of the pressure plate 424 at an angle 435 as the retaining block 434 moves.

[0060] The longitudinal drive cylinder 432 drives the longitudinal slide 433 to move longitudinally. The longitudinal movement of the longitudinal slide 433 causes the clamping block 434 to move longitudinally. The inclined surface 435 of the clamping block 434 is narrow at the front end and wide at the rear end. When the clamping block 434 moves forward longitudinally, the width of the inclined surface 435 that abuts against the pressure plate 424 increases, and the squeezing force on the lower end of the pressure plate 424 increases. The lower end of the pressure plate 424 shifts towards the fixture seat 421, and the upper end of the pressure plate 424 can be rotatably separated from the upper side wall of the fixture seat 421. At this time, the stator is in a movable state in the fixture seat 421, which meets the requirements for feeding and unloading the stator.

[0061] The fixture assembly 42 also includes a mounting block 422 and a return spring 423. The mounting block 422 is fastened to the side wall of the fixture seat 421. The pressure plate 424 is rotatably mounted on the mounting block 422. The return spring 423 is disposed between the lower end of the pressure plate 424 and the side wall of the fixture seat 421. When the clamping block 434 moves longitudinally backward, the width of the inclined surface 435 that abuts against the pressure plate 424 becomes narrower and narrower until it separates from the pressure plate 424. The inward force of the clamping block 434 on the pressure plate 424 becomes smaller and smaller until it has no force. The squeezed return spring 423 gradually extends elastically to drive the pressure plate 424 to return to its original position. The upper end of the pressure plate 424 moves relative to the mounting block 422 towards the fixture seat 421. The stator in the fixture seat 421 is fixed by the pressure plate 424, thus achieving that the stator is fastened in the fixture seat 421. By using the fixture assembly 42, the automatic fixing or loosening of the stator in the fixture seat 421 is achieved.

[0062] There are two pressure plates 424 and two clamping blocks 434. The two pressure plates 424 are symmetrically and elastically separable abutting against the upper side wall of the fixture seat 421. The two clamping blocks 434 are in one-to-one correspondence with the two pressure plates 424 and abut against each other with inclined surfaces 435. The symmetrical elastically separable abutting of the two pressure plates 424 against the upper side wall of the fixture seat 421 makes the pressure plates 424 press down on the stator more evenly, thus improving the stability of the overall structure.

[0063] The opening and closing drive assembly 43 also includes a pin 436, which is fastened to the longitudinal slide 433. The locking protrusion 425 includes an integrally connected spacer 4251 and an outer protrusion 4252. The front sides of the spacer 4251 and the outer protrusion 4252 are both flat. A telescopic spring 426 is provided between the sidewall of the mounting block 422 and the outer protrusion 4252. The locking protrusion 425 can move longitudinally to abut against the pin 436.

[0064] When the stator moves and rotates, the telescopic spring 426 is in an extended state, and the outer protrusion 4252 of the locking protrusion 425 abuts against the lower side of the pressure plate 424. The outer protrusion 4252 and the lower side of the pressure plate 424 form a platform contact, and the upper side of the pressure plate 424 presses the stator to prevent the stator from moving during the movement. When the stator moves to the side of the opening and closing drive assembly 43 and needs to be opened, the pin 436 abuts against the outer wall of the locking protrusion 425.
