Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic winding, in particular to a convenient automatic winding structure and a winding machine. Background Art
[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 is usually composed 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] Existing hook-type winding machines usually install the winding reel on the top of the product placement tooling, and the size of the winding reel is between the inner and outer diameters of the placement tooling. The lead wire length adjustment can only be controlled by increasing the number of winding turns. However, for the product electromagnetic technology process requiring 2 parallel, 4 parallel and above winding, the lead wires usually have 6, 12, 24 or more, and because the product process requires that the length of each lead wire needs to be greater than or equal to the circumference of the core, the existing method of increasing the number of winding turns will make the lead wires complex and form a spider web, making it difficult to retrieve the material after the winding operation is completed. The messy spider web-like lead wires will also inevitably increase the labor cost of the next operation process, which is not conducive to production.
[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. Utility Model Content
[0005] In order to solve the technical problem of the messy winding of the lead wires, the utility model provides a convenient automatic winding structure, which includes a machine base and a winding mechanism.
[0006] The winding mechanism is movably arranged on the machine base, and the winding mechanism includes a placing tool and a winding drum. The placing tool is movably connected to the machine base, and the winding drum is arranged on the placing tool. The outer diameter of the winding drum is larger than the outer diameter of the placing tool, and the winding drum is provided with a plurality of winding poles spaced apart from each other.
[0007] Furthermore, the convenient automatic winding structure also includes a wire hooking mechanism, which is arranged on the machine base, movably connected to the machine base, and arranged on the side of the winding mechanism, and can extend into the winding mechanism.
[0008] Furthermore, a hollow portion is provided on the placement tool, and the line hooking mechanism can extend into the placement tool from the hollow portion.
[0009] Furthermore, a crochet hook is provided in the placement tool.
[0010] Furthermore, the outer diameter of the wire winding drum is 1.5 to 2.5 times the outer diameter of the placement tool.
[0011] Furthermore, the plurality of winding poles are annular and evenly distributed on the winding drum.
[0012] Furthermore, the plurality of wire winding posts are all adjacent to the outer edge of the wire winding drum.
[0013] Furthermore, the number of the wire winding poles is 12, and the angle between two adjacent wire winding poles is 30°.
[0014] Furthermore, a plurality of observation holes are provided on the wire winding drum, and the plurality of observation holes are evenly and spaced apart on the wire winding drum.
[0015] The utility model also provides a winding machine, characterized in that: it comprises any one of the convenient automatic winding structures described above;
[0016] Furthermore, the winding machine also includes a winding nozzle, which is movably connected to the machine base and can extend into the winding mechanism.
[0017] Based on the above, the convenient automatic winding mechanism and winding machine provided by the utility model, compared with the prior art, increase the diameter of the winding drum and extend the distance from the winding column to the stator core placed in the tooling. The lead-out wire only needs to be wound around the winding column on the winding drum for about half a circle. The length of the lead-out wire is the circumference of the stator core or a slight margin. At this time, the length of the lead-out wire is an appropriate length, and there is no need to increase the number of winding circles. Thereby, the effect of reducing the number of winding circles of the lead-out wire on the winding drum is achieved, so that the lead-out wire on the winding drum tends to be regular, and there will be no complicated "spider web" lead-out wire, which is convenient for subsequent processing operations, not only reducing labor costs, but also improving production efficiency.

[0029] See also Figure 1 and Figure 2 , Figure 1A schematic structural diagram of a convenient automatic winding structure provided by an embodiment of the utility model; Figure 2 A schematic structural diagram of a winding mechanism provided in one embodiment of the utility model.
[0030] In order to solve the above technical problem of the messy winding of the lead wire, or to achieve at least one of the above advantages or other advantages, an embodiment of the utility model provides a convenient automatic winding structure. As shown in the figure, the convenient automatic winding structure includes a base 10 and a winding mechanism 20.
[0031] The winding mechanism 20 is movably arranged on the machine base 10. In a specific implementation, the winding mechanism 20 includes a placing tool 21 and a winding drum 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 to cooperate with the winding work. The winding drum 22 is arranged on the placing tool 21, and when the placing tool 21 rotates relative to the machine base 10, it can synchronously drive the winding drum 22 to rotate. The winding drum 22 is provided with a plurality of mutually spaced winding posts 30 for winding wire.
[0032] The outer diameter of the winding drum 22 is larger than the outer diameter of the placement tool 21. Specifically, the outer diameter of the winding drum 22 is equal to 1.5-2.5 times the outer diameter of the placement tool 21, which extends the distance from the winding column 30 to the stator core in the placement tool 21. The lead wire only needs to be wound around the winding column 30 on the winding drum 22 for about half a circle. The length of the lead wire is the circumference of the stator core or a little margin. At this time, the length of the lead wire is an appropriate length that meets the product process requirements.
[0033] In some preferred embodiments, please combine Figure 2 See also Figure 3 As shown in the figure, a plurality of winding poles 30 are annular and evenly distributed on the winding drum. Specifically, the plurality of winding poles 30 are close to the outer edge of the winding drum 22 (the edge of the side away from the placement of the tooling 21) to ensure that the winding drum 22 with a small outer diameter is used on the basis of adjusting and controlling the length of the lead-out wire, so as to avoid the outer diameter of the winding drum 22 being too large and occupying the equipment space.
[0034] The number of the winding poles 30 is 12, and the angle between two adjacent winding poles 30 is 30°, so that the lead-out wire can be easily wound and debugged by selecting the winding pole 30 at the best position.
[0035] In some preferred embodiments, due to the increase in the outer diameter of the winding drum 22, the manual line of sight may be obstructed by the winding drum 22 during the production process, and therefore, a plurality of observation holes 40 are provided on the winding drum 22. The plurality of observation holes 40 are evenly and spaced apart on the winding drum 22. During the winding process, the automatic winding state can be viewed in real time through the observation holes 40, which is convenient for debugging and monitoring.
[0036] On the basis of the above, the convenient automatic winding structure further includes a wire hooking mechanism 50. In specific implementation, the wire hooking mechanism 50 is arranged on the machine base 10. The wire hooking mechanism 50 is movably connected with the machine base 10, and the wire hooking mechanism 50 is arranged on the side of the winding mechanism 20, and the wire hooking mechanism 50 can move relative to the machine base 10 toward the winding mechanism 20.
[0037] The placement tool 21 is provided with a hollow portion 60, so that the wire hooking mechanism 50 can extend into the placement tool 21 through the hollow portion 60 to hook the lead wire to adjust and control the length of the lead wire. Preferably, the placement tool 21 is provided with a hook 70 for hooking the wire to assist the winding work.
[0038] In some preferred embodiments, the utility model further provides a winding machine, comprising the above-mentioned convenient automatic winding structure. In some preferred embodiments, the winding machine further comprises a winding nozzle 80, which is movably connected to the machine base 10 and can be extended into the winding mechanism 20.
[0039] In the specific winding process, the winding nozzle 80 first winds the wire on the winding column 30 to realize the function of winding the lead wire outside and controlling and adjusting the length of the lead wire. Then the winding nozzle 80 moves and extends into the placement tool 21 to wind the stator core. During the process, the hook needle 70 can stably hook the wire to assist the winding work. At the same time, the hooking mechanism 50 can extend into the placement tool 21 to hook the lead wire and control the length of the lead wire.
[0040] To sum up, compared with the prior art, the convenient automatic winding mechanism and winding machine provided by the utility model increase the diameter of the winding drum and extend the distance from the winding column to the stator core placed in the tooling. The lead-out wire only needs to be wound about half a circle along the winding column on the winding drum. The length of the lead-out wire is the circumference of the stator core or a slight margin. At this time, the length of the lead-out wire is an appropriate length, and there is no need to increase the number of winding turns. Thereby, the effect of reducing the number of winding turns of the lead-out wire on the winding drum is achieved, so that the lead-out wire on the winding drum tends to be regular, and there will be no complicated "spider web"-shaped lead-out wire, which is convenient for subsequent processing operations, not only reducing labor costs, but also improving production efficiency.
[0041] Although the terms such as placement tooling, hooking mechanism, and observation hole are used more frequently in this article, the possibility of using other terms is not excluded. 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.
[0042] 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.
[0043] 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.
