Description

Technical Field

[0001] This invention relates to the field of winding machines, and in particular to a core locking and rotating mechanism for use in winding machines, as well as the winding machine and winding method. Background Technology

[0002] During motor assembly, multiple iron cores need to be wound sequentially. Current technologies do not employ fixture components and shifting components to move the iron cores within the fixture component, failing to guarantee that each wound iron core is at the rotation center of the locking rotary drive component. This also prevents the consistent tension of the wire during winding. Furthermore, it hinders the prevention of eccentricity and inconsistent winding tension caused by the different positions of the iron cores when winding multiple cores sequentially. Therefore, based on this situation, there is an urgent need to develop an iron core locking rotary mechanism for winding machines, as well as a winding machine and winding method to meet practical application needs. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a core locking and rotating mechanism for a winding machine, as well as a winding machine and winding method.

[0011] As a preferred embodiment: the toggle shifting assembly includes a forward / backward drive device, a toggle drive device, and an opening drive device for driving the iron core to unlock in the fixture assembly. The toggle drive device is installed at the output end of the forward / backward drive device, and the opening drive device is installed at the output end of the toggle drive device.

[0012] As a preferred embodiment: the actuating drive device includes an actuating drive motor, a lead screw, and an actuating block. The actuating drive motor is mounted at the output end of the forward / reverse drive device, the lead screw is mounted at the output end of the actuating drive motor, and the lead screw rotates with the actuating block. The actuating block is detachably mounted around the outside of the mounting base. The clamping drive device includes a clamping drive cylinder and a clamping plate. The clamping drive cylinder is vertically mounted on the actuating block, and the clamping plate is mounted at the output end of the clamping drive cylinder.

[0036] The present invention is as follows Figure 1 As shown in Figure 12, a core locking and rotating mechanism for a winding machine includes a fixture assembly 10 for holding a plurality of cores, a locking and rotating drive assembly 20 for driving the cores to lock in the fixture assembly 10 and rotating the cores, and a shifting and moving assembly 30 for driving the fixture assembly 10 to move on the locking and rotating drive assembly 20; wherein:

[0037] The output end of the shifting component 30 corresponds to the fixture component 10; the locking rotary drive component 20 includes a locking drive device 21 and a rotary drive device 22, the output end of the locking drive device 21 is detachably abutting against the fixture component 10; the fixture component 10 is movably located at the output end of the rotary drive device 22.

[0038] The iron core is placed in the fixture assembly 10, and the locking drive device 21 in the locking rotation drive assembly 20 drives the iron core to lock in the fixture assembly 10; the rotation drive device 22 in the locking rotation drive assembly 20 drives the iron core to rotate to facilitate subsequent winding of the iron core; when one iron core is wound, the shifting assembly 30 shifts the iron core to move the position of the wound iron core, and moves the iron core to be wound to the rotation center position of the locking rotation drive assembly 20.

[0039] By employing the jig assembly 10 and the shifting assembly 30, the position of the iron core in the jig assembly 10 is moved, ensuring that each winding iron core is at the rotation center position of the locking rotation drive assembly 20. This guarantees that the tension of the wire is consistent for each iron core during the winding process, preventing eccentricity and different winding tension caused by the different positions of the iron cores when winding multiple iron cores sequentially. The mutual cooperation between the jig assembly 10 and the locking rotation drive assembly 20 locks and rotates the iron core in the jig assembly 10, ensuring that the iron core is locked in the jig assembly 10 during winding, thus guaranteeing the winding accuracy.

[0040] The fixture assembly 10 includes a mounting base 11 and a plurality of feeding and positioning devices 12. The plurality of feeding and positioning devices 12 are evenly distributed on the mounting base 11 at intervals. Each of the plurality of feeding and positioning devices 12 includes a feeding component 121 and a positioning component 122. The feeding component 121 is elastically and vertically mounted on the mounting base 11, and the positioning component 122 is elastically and vertically located in the feeding component 121.

[0041] Several iron cores are located on several feeding components 121. The feeding components 121 can be raised and lowered to facilitate the placement and movement of the iron cores. Several positioning components 122 rise and abut against the lower surface of the iron cores to lift and position the iron cores on the feeding components 121.

[0042] The feeding component 121 includes a sleeve 1211 located on the lower side and a feeding block 1212 located on the upper side. The positioning component 122 includes a lifting column 1221 located on the lower side, a positioning block 1222 located on the upper side, and a connecting column 1223 connected to the lifting column 1221. The lifting column 1221 is located in the sleeve 1211 in a lifting manner. When the lifting column 1221 rises, it drives the positioning block 1222 to rise. The positioning block 1222 can rise to abut against the lower surface of the iron core in the feeding block 1212. The connecting column 1223 extends out of the outer wall of the sleeve 1211 and is located on the sleeve 1211 in a flexible lifting manner.

[0043] A first spring 13 is provided between the feeding block 1212 and the mounting base 11. The upper end of the first spring 13 is connected to the feeding block 1212, and the lower end of the first spring 13 is connected to the lower side of the mounting base 11. A second spring 14 is provided between the lifting column 1221 and the mounting base 11. The upper end of the second spring 14 is connected to the lower side of the connecting column 1223, and the lower end of the second spring 14 is connected to the lower side of the mounting base 11.

[0044] The sleeve 1211 is provided with a limiting slot 12111 for limiting the lifting position of the connecting post 1223, and the connecting post 1223 is located in the limiting slot 12111 in a lifting manner.

[0045] The material feeding block 1212 moves up and down on the mounting base 11 via the first spring 13, and the positioning block 1222 moves up and down in the mounting base 11 via the second spring 14. The movement of the connecting column 1223 drives the movement of the lifting column 1221. The position of the connecting column 1223 is limited by setting the limit slot 12111.

[0046] The locking drive device 21 includes a locking drive cylinder 211 and a lifting shaft 212. The lifting shaft 212 is rotatably mounted on the output end of the locking drive cylinder 211. The lifting shaft 212 can rise and abut against the lower end of the positioning member 122 and the lower end of the feeding member 121 in sequence. The rotary drive device 22 includes a rotary drive motor 221 and a rotary disk 222. The rotary disk 222 is mounted on the output end of the rotary drive motor 221. The lifting shaft 212 can rise and is located at the center of the rotary disk 222.

[0047] The lower side of the lifting shaft 212 has an outwardly extending step. When the lifting shaft 212 rises, it first lifts the positioning component 122 to position the iron core; then it lifts the feeding component 121 to raise the whole structure. The rise of the feeding component 121 drives the iron core to be wound to rise, so that the iron core at the position to be wound is higher than the iron core that has not been wound, thus avoiding interference with the position of other iron cores waiting to be wound when the iron core is being wound. The lifting shaft 212 can be raised to the center position of the rotating disk 222, so that each winding iron core is located at the center of rotation when winding, preventing winding eccentricity and ensuring that the tension of the wire in each winding iron core is consistent.

[0048] The toggle shifting assembly 30 includes a forward / backward drive device 31, a toggle drive device 32, and an opening drive device 33 for driving the iron core to unlock in the fixture assembly 10. The toggle drive device 32 is mounted on the output end of the forward / backward drive device 31, and the opening drive device 33 is mounted on the output end of the toggle drive device 32.

[0049] The forward and backward drive device 31 includes a forward and backward drive cylinder and front and rear slides, which are installed at the output end of the forward and backward drive cylinder. The forward and backward drive device 31 drives the toggle drive device 32 and the clamping drive device 33 to move back and forth. The toggle drive device 32 toggles the position of the iron core. The clamping drive device 33 clamps several iron cores after all the iron cores are wound to facilitate material discharge.

[0050] The actuation drive device 32 includes an actuation drive motor 321, a lead screw, and an actuation block 322. The actuation drive motor 321 is mounted on the output end of the forward / reverse drive device 31, and the lead screw is mounted on the output end of the actuation drive motor 321. The lead screw and the actuation block 322 are rotatably engaged. The actuation block 322 is detachably wrapped around the outside of the mounting base 11. The clamping drive device 33 includes a clamping drive cylinder 331 and a clamping plate 332. The clamping drive cylinder 331 is vertically mounted on the actuation block 322, and the clamping plate 332 is mounted on the output end of the clamping drive cylinder 331. The clamping plate 332 is detachably clamped to the connecting column 1223.

[0051] By using the toggle drive device 32, it is easy to move the position to the center position of the rotary drive device 22, ensuring the consistency of the winding position of each iron core and preventing eccentricity when winding in sequence, which would result in different winding tension.

[0052] The feeding component 121 and the positioning component 122 of the jig assembly 10 cooperate to securely lock the iron core in the jig assembly 10 under the action of the locking drive device 21. The positioning block 1222 of the positioning component 122 abuts against the lower surface of the iron core to achieve precise positioning and ensure the quality and accuracy of the winding.

[0053] The rotary drive motor 221 of the rotary drive device 22 drives the rotary disk 222 to rotate. The lifting shaft 212 is rotatably mounted on the output end of the locking drive cylinder 211 through the bearing and is located at the center of the rotary disk 222, which can make the iron core rotate stably and avoid the winding problem caused by uneven speed.

[0054] The forward and backward drive device 31, the toggle drive device 32 and the clamping drive device 33 of the shifting component 30 work together to quickly and accurately drive the fixture component 10 to move on the locking rotary drive component 20, thereby improving the shifting efficiency of the iron core between different work stations and thus improving the efficiency of the entire winding operation.

[0055] A winding machine with a core locking and rotating mechanism for use in a winding machine, the winding machine further includes a wire pulling mechanism 40 for pulling wire to wind the core. The wire pulling mechanism 40 includes a vertical drive assembly 41, a longitudinal drive assembly 42, a transverse drive assembly 43, a wire tension adjustment assembly 44, a wire cutting assembly 45, and a wire nozzle 46. The longitudinal drive assembly 42 is installed at the output end of the vertical drive assembly 41, the transverse drive assembly 43 is installed at the output end of the longitudinal drive assembly 42, and the wire tension adjustment assembly 44, the wire cutting assembly 45, and the wire nozzle 46 are all installed at the output end of the transverse drive assembly 43.

[0056] The vertical drive assembly 41, longitudinal drive assembly 42 and transverse drive assembly 43 all employ a drive motor, a ball screw and a sliding seat. The ball screw is installed at the output end of the drive motor and rotates in conjunction with the sliding seat.

[0057] The wire tension adjustment assembly 44 includes a tension adjustment drive motor 441, a drive wheel 442, a driven wheel 443, and a tension wheel 444. The drive wheel is installed at the output end of the tension adjustment drive motor 441, and the wound wire passes through the drive wheel 442, the driven wheel 443, and the tension wheel 444. The wire cutting assembly 45 is a pneumatic shear.

[0058] The winding mechanism 40 of the winding machine has vertical, longitudinal and transverse drive components 43, as well as wire tension adjustment components 44 and wire cutting components 45, which can realize precise wire pulling, tension adjustment and wire cutting operations to meet various needs of the winding process.

[0059] A winding method for the winding machine includes the following steps:

[0060] First, several iron cores are placed on the fixture assembly, and the locking drive device drives the first iron core to lock in the fixture assembly;

[0061] Second, the rotary drive device drives the fixture assembly to rotate, the wire tension adjustment component in the wire pulling mechanism adjusts the tension of the wire, and the wire nozzle in the wire pulling mechanism moves its position under the drive of the vertical drive component, the longitudinal drive component and the transverse drive component. The movement of the wire nozzle, in conjunction with the rotation of the iron core, winds the first iron core.

[0062] Third, after the first iron core is wound, the shifting component drives the fixture component to move to a new position, and the wire pulling mechanism winds the next iron core.

[0063] Fourth, after all the iron cores are wound, the wire cutting component in the wire pulling mechanism cuts the wound wire, cutting off the initial wire and the tail wire;

[0064] Fifth, after the wire is cut, the jig assembly unlocks and releases the locking mechanism on all iron cores to facilitate the discharge of the iron cores.

[0065] The key design feature of this invention is that by employing a jig assembly and a shifting assembly to move the position of the iron core in the jig assembly, each winding iron core is positioned at the rotation center of the locking rotation drive assembly, ensuring consistent wire tension for each iron core during winding. This prevents eccentricity and inconsistent winding tension caused by the different positions of the iron cores when winding multiple iron cores sequentially. Furthermore, the cooperation between the jig assembly and the locking rotation drive assembly locks and rotates the iron core in the jig assembly, ensuring that the iron core is locked within the jig assembly during winding and guaranteeing winding accuracy.

[0066] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
