Description

Technical Field

[0001] The utility model relates to the technical field of motor coil assembly, in particular to a block-type automatic circle-joining mechanism. Background Art

[0002] The winding is formed by splicing multiple stators. In the production operation, multiple stators are usually placed in a circular mold, and then the multiple stators are spliced ​​into a circular winding by translating the mold. For example, Chinese Patent 202220796701.0 discloses a high-precision circular splicing mechanism for motor coils, which includes a machine, a translation mechanism, and a circular splicing mechanism. The circular splicing mechanism includes a circular splicing mold, a push block, a first cylinder, a lower mold core assembly, and an upper mold core assembly. Multiple first cylinders are located on the circumferential outer side of the circular splicing mold and the output end is connected to the push block. Multiple push blocks respectively support and squeeze the stators, thereby eliminating the gap between the stators. The lower mold core assembly includes a vertical drive device and a mold core. The mold core is provided with a circular iron core at the end center of the circular splicing mold, and a circle of limit rings arranged on the circumferential outer side of the mold core. The mold pushes the push block through multiple first cylinders, so that multiple stators gather together, thereby splicing and forming a winding. However, it uses too many driving devices, which wastes resources and production costs. Utility Model Content

[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0015] like Figure 1 As shown, it is a schematic diagram of the structure of the block-type automatic circle-making mechanism provided by the utility model. The block-type automatic circle-making mechanism includes a base 10, a rotating assembly 20 arranged on one side of the base 10, and a plurality of circle-making assemblies 30 arranged at intervals on one side of the rotating assembly 20. It can be imagined that the block-type automatic circle-making mechanism also includes some other functional modules, such as a power module, a screw module, etc., which are technologies well known to those skilled in the art and will not be described one by one here.

[0016] Please also read Figures 2 to 4. It should be noted that the block-type automatic circle-joining mechanism is used to combine and assemble several coil stators 40 into a winding. An arc-shaped groove 41 and an arc-shaped convex strip 42 are respectively provided on both sides of the coil stator 40, and the groove 41 on one coil stator 40 corresponds to and matches the convex strip 42 on the other coil stator 40, so that the two coil stators 40 are assembled together, so that several coil stators 40 are fixedly spliced ​​into a circular winding. An arc-shaped circular groove 43 is provided on one side of the coil stator 40, and the circular groove 43 cooperates with part of the circle-joining component 30, so that the coil stator 40 is fixedly placed on part of the circle-joining component 30 to play a positioning function. The specific cooperation will be described below.

[0017] The base 10 is used to carry various components so that they can be matched with each other, thereby completing the circle assembly operation of a plurality of the coil stators 40 .

[0018] The rotating assembly 20 includes a rotating motor 21 and a rotating disk 22 disposed at an output end of the rotating motor 21 .

[0019] The rotating motor 21 can drive the rotating disk 22 to rotate. A plurality of inclined slots 23 are arranged at intervals on the edge of the rotating disk 22, and the inclined slots 23 are arranged to intersect with the radius of the rotating disk 22. The inclined slots 23 can cooperate with part of the circle assembly 30 to assemble a plurality of the coil stators 40 into a circle, and the specific cooperation method will be described below.

[0020] The plurality of circle-jointing components 30 correspond to the plurality of inclined grooves 23 on the turntable 22 , respectively. The circle-jointing components 30 include a guide rail 31 disposed on the base 10 , a U-shaped slider 32 slidably disposed on the guide rail 31 , and a roller 33 disposed at the opening of the U-shaped slider 32 .

[0021] The guide rail 31 is arranged toward the center of the turntable 22, so that the moving direction of the U-shaped slider 32 is toward the center of the turntable 22. The edge of the turntable 22 is located in the opening of the U-shaped slider 32 and is spaced apart from the inner surface of the U-shaped slider 32, so that when the U-shaped slider 32 slides on the guide rail 31, it will not interfere with the turntable 22. When all the U-shaped sliders 32 move synchronously toward the center of the turntable 22, they will form a closed circle, thus completing the circle assembly operation of the plurality of coil stators 40.

[0022] The plurality of rollers 33 are respectively located in the plurality of inclined slots 23 and are in contact with the inner wall gap of the inclined slots 23. When the turntable 22 is driven by the rotary motor 21 to rotate, the rollers 33 will move in the inclined slots 23, thereby driving the U-shaped slider 32 to move on the guide rail 31. The rotation amplitude of the turntable 22 directly controls the displacement length of the U-shaped slider 32 on the guide rail 31, thereby changing the closing degree of each U-shaped slider 32, so that it can adapt to the splicing circles of the coil stators 40 of different sizes, thereby improving the adaptability of the mechanism.

[0023] The U-shaped slider 32 has at least two placement grooves 34 on one side away from the guide rail 31. The two placement grooves 34 have different sizes and specifications, so that they can accommodate the coil stators 40 of two different sizes. This further improves the adaptability of the mechanism. A round bar 35 is protruded on the inner side wall of the two placement grooves 34 away from the center of the rotating disk 22. The round bar 35 matches the round groove 43 on the coil stator 40, thereby positioning the coil stator 40 placed in the placement groove 34.

[0024] The block-type automatic circle-joining mechanism also includes a plurality of detectors 50 respectively arranged on one side of the plurality of circle-joining components 30, and the output direction of the detector 50 is toward the coil stator 40 placed on the circle-joining component 30, so as to determine whether the coil stator 40 exists on the circle-joining component 30, thereby determining whether to perform the circle-joining operation.

[0025] Compared with the prior art, the block-type automatic circle-joining mechanism provided by the utility model can complete the circle-joining operation of a plurality of the coil stators 40 by driving the rotating disk 22 to rotate through the rotating motor 21, thereby greatly reducing the waste of resources and saving costs. The closing degree of each U-shaped slider 32 is controlled by the rotation amplitude of the rotating disk 22, so that the circle-joining operation of various types of coil stators 40 of different sizes can be completed, thereby improving the adaptability of the mechanism.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
