Abstract
Description
Technical Field

[0002] The stator winding production in the motor industry mostly uses hook-type winding machines for automatic winding to save labor costs and improve production efficiency. It usually consists of a winding nozzle and a placement tool. The winding nozzle clamps the wire and winds the wire evenly on the stator in the placement tool.
[0003] At present, the existing hook-type winding machine is usually equipped with 11 V-shaped hooks that are staggered up and down at the bottom of the placement tooling to assist the winding work and adjust the lead-out wire length. However, as the diameter of the wound wire increases, the pulling force of the winding nozzle is also greater, and the V-shaped hook needs to withstand the greater pulling force from the wire. In addition, due to the space limitation of the placement tooling itself, the V-shaped hook cannot be thickened to increase its tensile strength. When winding a large wire diameter, it is easy to have excessive pulling force, causing the V-shaped hook to deform or cause the wire to fall off the V-shaped hook, resulting in the inability to adapt to the needs of winding a large wire diameter, thereby affecting the winding work.
[0004] It should be noted that the information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to a person skilled in the art.

[0033] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a large-diameter automatic winding structure provided by an embodiment of the utility model; Figure 2 This is a schematic structural diagram of a wire winding mechanism and a wire hooking mechanism provided in one embodiment of the utility model.
[0034] In order to solve the above technical problem of not being able to adapt to the large wire diameter winding requirements, or to achieve at least one of the above advantages or other advantages, an embodiment of the utility model provides a large wire diameter automatic winding structure. As shown in the figure, the large wire diameter automatic winding structure includes a machine base 10, a winding mechanism 20 and a wire hooking mechanism 30.
[0035] The winding mechanism 20 is arranged on the machine base 10, and is movably connected to the machine base 10. The winding mechanism 20 can rotate relative to the machine base 10 to cooperate with the winding work. A hook 40 is arranged in the winding mechanism 20, and a hollow part 50 is arranged on the winding mechanism 20.
[0036] In specific implementation, the winding mechanism 20 includes a placing tool 21 and a winding chassis 22. The placing tool 21 is movably connected to the machine base 10, and the placing tool 21 can rotate relative to the machine base 10. The hook 40 is arranged in the placing tool 21.
[0037] Please combine Figure 2 See also Figure 3 , Figure 4 and Figure 5Specifically, as shown in the figure, there are two hooks 40, which are arranged at 90 degrees at the bottom of the placement tooling 21. A top screw groove 41 is provided at the connection between the hook 40 and the placement tooling 21. The hook 40 is mutually engaged with the placement tooling 21 through the top screw groove 41, and is fastened with the placement tooling 21 through a bolt, so as to ensure that the hook 40 is firmly installed on the placement tooling 21.
[0038] Preferably, the hook needle 40 is an inverted L-shaped hook needle, which has a larger winding space. At the same time, when the tooling 21 is placed and rotated, it can hook the lead wire more stably and will not fall off.
[0039] The hollow portion 50 is located on the placement tool 21, and the hollow angle of the hollow portion 50 is greater than 180 degrees. It is ensured that during the winding process, even if the placement tool 21 rotates, the wire hooking mechanism 30 can extend into the placement tool 21 to clamp the lead wire, hook the lead wire out of the placement tool 21, and control the length of the lead wire.
[0040] The wire winding chassis 22 is arranged on the placing tool 21. When the placing tool 21 rotates relative to the machine base 10, the wire winding chassis 22 can be driven to rotate synchronously.
[0041] The winding base 22 is provided with winding posts 60. Preferably, the number of winding posts 60 is 12. In the specific winding process, the winding nozzle 70 first winds the wire on the winding posts 60 to realize the function of winding the lead wire outside and controlling and adjusting the length of the lead wire, after which the copper wire can be further wound on the stator core.
[0042] The wire hooking mechanism 30 is arranged on the machine base 10 and is movably connected to the machine base 10. In specific implementation, the wire hooking mechanism 30 is movably arranged on the side of the winding mechanism 20, and the wire hooking mechanism 30 can extend into the placement tooling 21 through the hollow portion 50 to hook the lead wire out of the placement tooling 21.
[0043] It is understandable that the relative position of the wire hooking mechanism 30 and the wire winding mechanism 20 can be adjusted according to specific practical needs, as long as it is ensured that the wire hooking mechanism 30 can be extended into the placement tool 21.
[0044] On the basis of the above, the thread hooking mechanism 30 includes a driving unit 31, a first cylinder 32, a second cylinder 33 and a clamping hand 34. In specific implementation, the driving unit 31 is movably connected to the machine base, and the driving unit 31 can move relative to the machine base 10. The first cylinder 32 is arranged on the driving unit 31, and the driving unit 31 can drive the first cylinder 32 to move. The second cylinder 33 is arranged on the first cylinder 32, and the first cylinder 32 can control the second cylinder 33 to move in the vertical direction. The clamping hand 34 is transmission-connected to the second cylinder 33, and the second cylinder 33 can control the clamping hand 34 to open and close. Preferably, the thread hooking mechanism 30 also includes a thread hooking wheel 35, and the thread hooking wheel 35 is arranged on the clamping hand 34.
[0045] In the specific winding process, when the lead wire needs to be hooked out of the placement tooling 21, the driving unit 31 moves, driving the first cylinder 32, the second cylinder 33 and the gripper 35 to move synchronously toward the placement tooling 21, so that the gripper 34 extends into the placement tooling 21 through the hollow portion 50, and the first cylinder 32 controls the second cylinder 33 to move in the vertical direction to ensure that the gripper 34 moves to a suitable position. At this time, the second cylinder 33 controls the gripper 34 to open, and after the hooking wheel 35 clamps the lead wire, the second cylinder 33 controls the gripper 34 to close. The driving unit 31 moves in the opposite direction, so that the lead wire is hooked out of the placement tooling 21 by the hooking wheel. By setting and controlling the moving distance of the driving unit 31, the function of controlling the length of the lead wire can be realized.
[0046] In some preferred embodiments, the utility model also provides a winding machine, comprising the above-mentioned large-diameter winding structure. Specifically, the winding machine also includes a winding nozzle 70, which is movably connected to the machine base 10, and the winding nozzle 70 can be inserted into the winding mechanism 20. In the specific winding process, the winding nozzle 70 can clamp the wire and move, and extend into the placement tooling 21 to wind the stator core. During the process, the hook needle 40 can stably hook the wire to assist the winding work, and at the same time, the hook wheel 35 can extend into the placement tooling 21 to hook the lead wire and control the length of the lead wire.
[0047] To sum up, compared with the prior art, the large-diameter automatic winding structure and winding machine provided by the utility model are different from those provided by the prior art. A wire hooking mechanism is arranged on the side of the winding mechanism. The wire hooking mechanism can hook the lead wire out of the placement tooling and adjust the length of the lead wire. The hook hook only needs to realize the function of auxiliary winding. By designing the function of controlling the length of the lead wire outside the winding mechanism, the structure inside the placement tooling is simplified, and the space inside the placement tooling is released, so that the hook hook can adopt a thickened design, thereby improving the tensile strength of the hook hook, avoiding deformation of the hook hook or the problem of wire falling off the hook hook, adapting to the needs of large wire winding, and improving productivity.

These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
[0049] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the utility model can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be used as a limitation on the claim.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
