[0002] Yokes are optional components for electromagnets. During production, sheet yokes are typically used. During transportation and storage, the yokes are typically wound into coils. In actual production, small coils of yokes may need to be rewound and combined into larger coils.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology: in order to make the large roll of yoke iron tightly rolled together during the rewinding process, it is necessary to control the unwinding resistance to keep the yoke iron sheet in a straight state, and at the same time, the yoke iron sheet must have a certain tension. However, the current rewinding equipment is not convenient to adjust the unwinding resistance and tension of the yoke iron roll during operation, which affects the rewinding quality of the yoke iron roll. Summary of the Invention

[0004] In order to facilitate the adjustment of the unwinding resistance and tension of the yoke iron roll and improve the winding quality of the yoke iron roll, the present application provides a yoke iron roll rewinding machine.

[0005] The present application provides a yoke coil rewinding machine that adopts the following technical solution:

The sliding arm slides radially along the yoke iron roll, and the air hammer assembly is used to knock the edge of the yoke iron roll.

[0010] By adopting the above technical solution, when the yoke roll is rewound, the unwinding drive assembly drives the unwinding disk to rotate actively, so that the yoke roll is unwound. The staff pulls the end of the yoke roll through the first tensioning block and the second tensioning block and fixes it on the winding disk. Then the winding drive assembly drives the winding disk to rotate to rewind the yoke roll. During the unwinding process of the yoke roll, the unwinding resistance of the yoke roll is adjusted by the resistance adjustment assembly, so that the yoke is in a straight state. At the same time, the yoke is further straightened when passing between the first tensioning block and the second tensioning block, so that the yoke sheet maintains a certain tension. The tension can also be adjusted by sliding the second tensioning block. Finally, it is convenient to achieve synchronous adjustment of the unwinding resistance and tension of the yoke roll during the rewinding process, thereby improving the winding quality of the yoke roll. During the winding process of the yoke roll, the diameter of the yoke roll gradually increases, and the sliding arm slides along the radial direction of the yoke roll.

At this time, the brake motor drives the unwinding disk to rotate actively for unwinding.

[0013] When the brake motor is locked, the resistance adjustment component can be used to adjust the clamping force on the driving wheel so that there is a certain friction between the driving wheel and the limit plate, thereby realizing the adjustment of the driving shaft rotation resistance and steplessly adjusting the rotation resistance of the unwinding disk as needed.

When the unwinding spindle is flipped to a horizontal state, it is convenient to use a forklift to hang the yoke iron roll on the unwinding spindle, and then the spindle box is reset, thereby facilitating the loading of the unwinder.

[0019] Optionally, the tensioning machine further includes a tensioning base, the tensioning seat is slidably arranged on the tensioning base, and the tensioning seat slides along a transmission direction perpendicular to the yoke.

[0020] By adopting the above technical solution, the tensioning seat is arranged on a slidable sliding seat, and the position of the tensioning seat is adjusted by sliding the sliding seat, thereby further facilitating the use of the tensioner.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-9 This application is described in further detail.

[0045] The embodiment of the present application discloses a yoke roll rewinding machine.

[0046] Reference Figure 1 A yoke coil rewinding machine includes an unwinder 1, a tensioner 3, and a winding machine 2, which are arranged in sequence. A small yoke coil to be rewound is placed on the unwinder 1, and the end of the yoke coil is pulled through the tensioner 3 to the winding machine 2 for winding. During the rewinding process, the unwinder 1 adjusts the unwinding resistance of the yoke coil, while the tensioner 3 adjusts the tension of the yoke coil.

[0047] Reference Figure 2 and Figure 3The unwinding machine 1 includes an unwinding frame 11, an unwinding disk 12, an unwinding drive assembly 13 and a resistance adjustment assembly 14. A spindle box 15 is provided on the unwinding frame 11. The unwinding drive assembly 13 includes a brake motor 131, a reducer 132, a driving shaft 133 and an unwinding spindle 134. The reducer 132 is fixedly arranged on the side wall of the spindle box 15. The brake motor 131 is fixedly connected to the reducer 132. The motor shaft of the brake motor 131 is connected to the input shaft of the reducer 132. The output shaft of the reducer 132 is vertically arranged. The driving shaft 133 is coaxially fixedly connected to the output shaft of the reducer 132. The unwinding spindle 134 is rotatably arranged inside the spindle box 15. The unwinding spindle 134 is arranged parallel to the driving shaft 133. The top end of the unwinding spindle 134 extends out of the spindle box 15. The driven wheel 1341 is coaxially fixedly sleeved on the outside of the unwinding spindle 134.

[0048] Reference Figure 2 and Figure 3 A limiting plate 1331 is coaxially fixed on the driving shaft 133, and a driving wheel 1332 is loosely sleeved on the driving shaft 133. The driving wheel 1332 is located on the side of the limiting plate 1331 away from the reducer 132. A driven wheel 1341 is coaxially fixed on the unwinding main shaft 134, and the driving wheel 1332 and the driven wheel 1341 are driven by a chain.

[0049] Reference Figure 2 and Figure 3 The resistance adjustment assembly 14 includes an adjusting drive member 141 and a pressing member 142. The adjusting drive member 141 is a cylinder. The cylinder body of the adjusting drive member 141 is fixedly arranged on the side of the reducer 132 away from the driving shaft 133. The piston rod of the adjusting drive member 141 slides through the reducer 132 and the driving shaft 133 and extends out of the driving shaft 133. The pressing member 142 is rotatably connected to the piston rod of the adjusting drive member 141. In this embodiment, the pressing member 142 is a pressing sleeve. The side of the pressing member 142 close to the limiting plate 1331 contacts the driving wheel 1332.

[0050] Reference Figure 2 and Figure 3 When the brake motor 131 is working, the drive member 141 is adjusted to drive the pressing member 142 to press the driving wheel 1332. The torque of the brake motor 131 is output to the unwinding spindle 134 through the chain drive, causing the unwinding reel 12 to rotate actively. When the brake motor 131 stops working, the piston rod of the drive member 141 is adjusted to extend or retract, thereby adjusting the pressing force of the pressing member 142 on the driving wheel 1332, thereby adjusting the friction between the driving wheel 1332 and the limiting plate 1331, and realizing stepless adjustment of the rotational resistance of the unwinding spindle 134, so that the yoke iron roll is in a straight state during the winding process.

[0051] Reference Figure 2To facilitate the loading of the yoke coil, the spindle box 15 is rotatably mounted on one side of the unwinding frame 11, with the rotation axis of the spindle box 15 being horizontally mounted. A connecting lug 152 is fixedly mounted on one side of the spindle box 15, extending to the bottom of the spindle box 15. A flip cylinder 151 is mounted on the unwinding frame 11. The cylinder body of the flip cylinder 151 is hinged to the unwinding frame 11, and the piston rod of the flip cylinder 151 is hinged to the connecting lug 152. When the piston rod of the flip cylinder 151 is extended or retracted, it drives the entire spindle box 15 to flip. When the unwinding spindle 134 is rotated to a horizontal state, it is convenient to hang the yoke coil on the unwinding spindle 134 using a forklift.

[0052] Reference Figure 4 The tensioning machine 3 includes a tensioning base 35, a tensioning base 31, a first tensioning block 32, a tensioning adjustment frame 33 and a second tensioning block 34. The tensioning base 35 is horizontally arranged on one side of the unwinding machine 1. The tensioning base 31 is set to slide on the tensioning base 35. The tensioning base 31 slides along the length direction of the tensioning base 35. The sliding of the tensioning base 31 is realized by the cooperation of the slide rail and the slider.

[0053] Reference Figure 4 The first tensioning block 32 is vertically mounted on the tensioning base 31 and fixedly connected to the tensioning base 31. The tensioning adjustment frame 33 is fixedly mounted on the tensioning base 31. The second tensioning block 34 is vertically mounted and slidably mounted on the tensioning adjustment frame 33. The sliding of the second tensioning block 34 is achieved by a cylinder fixed to the tensioning adjustment frame 33. A gap is left between the first tensioning block 32 and the second tensioning block 34 for the yoke to pass through. The sides of the first tensioning block 32 and the second tensioning block 34 that are close to each other are both curved.

[0054] Reference Figure 4 When the yoke is rolled back, the yoke is placed between the first tensioning block 32 and the second tensioning block 34, and the second tensioning block 34 is driven to move by the extension and contraction of the cylinder piston rod, so that the friction force exerted on the yoke when it passes between the first tensioning block 32 and the second tensioning block 34 is reduced.

[0055] Reference Figure 5 、 Figure 6 and Figure 7The winding machine 2 includes a winding frame 21, a winding reel 22, a winding drive assembly 23 and a support assembly 24. The winding drive assembly 23 includes a winding motor 231, a reduction gearbox 232 and a winding spindle 233. The winding motor 231 and the reduction gearbox 232 are both fixedly mounted on the winding frame 21. The input shaft of the reduction gearbox 232 is coaxially fixedly connected to the motor shaft of the winding motor 231, and the winding spindle 233 is coaxially fixedly connected to the motor shaft of the winding motor 231. The winding spindle 233 is arranged vertically, with the bottom end of the winding spindle 233 coaxially fixedly connected to the output shaft of the reduction gearbox 232, and the top end of the winding spindle 233 coaxially fixedly connected to the winding reel 22. The winding motor 231 drives the winding spindle 233 to rotate.

[0056] Reference Figure 5 and Figure 7 The support assembly 24 includes a support base 241 and support rollers 242. The support base 241 is fixedly mounted on the winding frame 21. Several support bases 241 are evenly distributed along the circumference of the winding reel 22, and each support base 241 is equipped with a support roller 242. Each support roller 242 includes a lower roller 2421 and an upper roller 2422. The lower roller 2421 is fixedly mounted on the support base 241, with the axis of the lower roller 2421 forming an acute angle with the axis of the winding reel 22. Each upper roller 2422 is rotatably coupled to the lower roller 2421. The upper rollers 2422 have chamfered edges 2423. The winding reel 22 is mounted horizontally on the support assembly 24, with the bottom of the winding reel 22 abutting against the chamfered surfaces 2423.

[0057] Reference Figure 5 To keep the edges of the yoke coil neat after winding, a tidying rack 41 is fixed to the winding frame 21. The tidying rack 41 is higher than the yoke coil. A slide 42 is slidably mounted on top of the tidying rack 41. The slide 42 is radially arranged along the winding reel 22 and slides along its own length. During the winding process, a worker uses a hammer on the slide 42 to strike the edges of the yoke coil, thereby straightening the edges.

[0058] Reference Figure 5 and Figure 8 A pneumatic hammer manipulator 5 is also provided on the winding frame 21. The pneumatic hammer manipulator 5 includes a pneumatic hammer bracket 51, a sliding arm 52 and a pneumatic hammer assembly 53. The pneumatic hammer bracket 51 is fixedly set on the winding frame 21, and the sliding arm 52 is radially arranged along the winding disk 22. The sliding arm 52 is slidably set on the pneumatic hammer bracket 51. The sliding arm 52 is higher than the yoke iron roll. The sliding arm 52 slides along its own length direction. The sliding of the sliding arm 52 is transmitted by a gear rack, and the sliding of the sliding arm 52 is guided and limited by a slide rail and a slider.

[0059] Reference Figure 9The pneumatic hammer assembly 53 includes a pneumatic hammer mounting bracket 531, a pneumatic hammer body 532, an auxiliary positioning module 533, and a controller 534. The pneumatic hammer mounting bracket 531 is fixedly mounted at the end of the sliding arm 52, and the pneumatic hammer body 532 is fixedly mounted on the pneumatic hammer mounting bracket 531. The auxiliary positioning module 533 and the controller 534 are both mounted on the pneumatic hammer mounting bracket 531. In this embodiment, the auxiliary positioning module 533 is a positioning camera. The auxiliary positioning module 533 and the pneumatic hammer body 532 are both electrically connected to the controller 534.

[0060] Reference Figure 5 and Figure 9 During the winding process of the yoke coil, the staff can also control the operation of the pneumatic hammer manipulator 5, and either the pneumatic hammer manipulator 5 or the slide 42 is used. As the yoke coil rotates around the reel 22, the diameter gradually increases. The auxiliary positioning module 533 is used to locate the position to be struck, and the signal is transmitted to the controller 534. The controller 534 controls the sliding speed of the sliding arm 52 according to the winding speed, and at the same time controls the pneumatic hammer body 532 to strike the position to be struck.

[0061] The operating principle of the yoke coil rewinding machine according to the embodiment of the present application is as follows: When the yoke coil begins to unwind, the piston rod of the regulating drive member 141 contracts, pressing the driving wheel 1332 against the limiting plate 1331, thereby transmitting power between the driving wheel 1332 and the driving shaft 133. The brake motor 131 then drives the unwinding reel 12 to rotate, unwinding the yoke coil. A staff member pulls the end of the yoke coil through the first and second tensioning blocks 32 and 34, and then secures it to the winding reel 22.

[0062] The winding motor 231 then drives the winding reel 22 to rotate and rewind the yoke roll. During the unwinding process, the friction between the driving wheel 1332 and the limit plate 1331 is adjusted by controlling the contraction pressure of the piston rod of the resistance adjustment assembly 14, thereby adjusting the unwinding resistance of the yoke roll and keeping the yoke roll in a straight state. At the same time, the sliding of the second tensioning block 34 adjusts the friction force exerted on the yoke as it passes between the first tensioning block 32 and the second tensioning block 34, thereby adjusting the tension of the yoke roll. Ultimately, this facilitates the synchronous adjustment of the unwinding resistance and tension of the yoke roll during the rewinding process, ensuring the quality of the winding.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
