The electric coil is an important structure inside the motor and an important component for generating a magnetic field. The installation methods of the coil inside the motor are divided into plug-in type and winding type. The plug-in type assembly of the coil usually involves inserting a prepared coil (usually a formed coil) into the corresponding position of the stator or rotor.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0044] Example 1, please refer to the attached Figure 1 - Fig.10 As shown, it is the first embodiment of the present invention, which provides an automatic wire plugging machine for coil assembly, including a wire plugging platform 1, three assembly grooves are evenly opened on the top of the wire plugging platform 1, and a clamping assembly 2 is installed in the assembly groove. The clamping assembly 2 includes a sliding seat 21, and a protective shell 31 is slidably installed on the upper surface of the sliding seat 21. A first motor 32 is fixed inside the protective shell 31, and a rotating clamp 33 is fixed at the output end of the first motor 32 and located on the top of the protective shell 31;

[0045] In the above description, after the stator is clamped between the three rotating clamps 33 , the rotating clamps 33 are controlled to rotate by the first motor 32 , thereby driving the installed stator to rotate together.

[0046] Three workstations are formed between the three clamping assemblies 2, two of which are provided with coil conveying assemblies 4, which are respectively connected to the upstream and downstream equipment of the coil production line, and the coil conveying assemblies 4 are used for coil conveying, and another workstation is provided with a wire insertion mechanism 8;

[0047] Two slidable side baffles 61 are installed above the coil conveying assembly 4;

[0048] The plugging mechanism 8 includes a connecting plate 85, a fifth electric push rod 86 is fixed to one end of the bottom of the connecting plate 85, a second wire support rod 88 is fixed to the other end of the bottom of the connecting plate 85, a first wire support rod 87 is fixed to the output end of the fifth electric push rod 86, and a lead spring 89 is fixed to the bottom of the first wire support rod 87;

[0049] In the above, when inserting the wire, the coil is set between the second wire support rod 88 and the first wire support rod 87, and the first wire support rod 87 is controlled to move by the fifth electric push rod 86, so that the coil is tightened and guided by the lead spring 89 when inserted into the slot of the stator to ensure the accuracy of the slot.

[0050] In a preferred embodiment, please refer to Figure 3 and Figure 4 The shape of the sliding seat 21 is U-shaped, a sliding rail is arranged on the upper surface of the sliding seat 21, the bottom of the protective shell 31 is slidably connected to the sliding rail, a spring member 22 is arranged at one end of the protective shell 31, and the other end of the spring member 22 is in contact with the inner wall of one end of the sliding seat 21.

[0051] In this embodiment, the protective shell 31 and the sliding seat 21 can slide, and the spring member 22 arranged therebetween can provide a thrust so that the protective shell 31 can always be located at one end of the sliding seat 21 without being subjected to pressure. When the stator is clamped by a plurality of clamping assemblies 2, the stator pushes the rotating clamping member 33, so that the protective shell 31 is squeezed by the spring member 22 to contract, and the protective shell 31 is maintained to apply pressure to the stator under the push of the spring member 22 to keep the stator fixed. The spring member 22 arranged in the same manner makes the clamping of the stator by the rotating clamping member 33 more flexible, and facilitates the disassembly and assembly of the stator from the rotating clamping member 33.

[0052] Secondly, please also refer to Figure 3 and Figure 4 A first guide rod 25 is fixed to one end of the protective shell 31, and the spring member 22 is located on the outside of the first guide rod 25, and the spring member 22 is slidably connected to one end of the sliding seat 21. The clamping assembly 2 also includes a first electric push rod 23, which is installed at one end of the assembly groove. A telescopic sleeve 24 is provided at the output end of the first electric push rod 23, and the telescopic sleeve 24 is fixed to one end of the sliding seat 21. One end of the first guide rod 25 is inserted into the telescopic sleeve 24 and is slidably connected to the telescopic sleeve 24.

[0053] In the above, the first guide rod 25 is set to limit the spring member 22, which plays a role in assisting the extension and retraction of the spring member 22 and maintaining the normal use of the spring member 22. At the same time, the first electric push rod 23 is set to push the telescopic sleeve 24 to extend and retract, and can control the sliding of the protective shell 31, thereby directly adjusting the position between the three rotating clamps 33, which can be suitable for stators of different specifications for wiring.

[0054] Secondly, please also refer to Figure 3 and Figure 4 The top and bottom of the rotating clamp 33 are slidably connected with a height limit plate 34, and the internal rotation of the rotating clamp 33 is connected with an adjusting threaded rod 35, and the upper and lower ends of the adjusting threaded rod 35 are respectively provided with threads with opposite spiral directions, and the upper and lower ends of the adjusting threaded rod 35 are respectively threadedly connected with the height limit plate 34, and a knob 36 is fixed on the top of the adjusting threaded rod 35 and above the rotating clamp 33.

[0055] In the above, the adjusting threaded rod 35 can be driven to rotate by rotating the knob 36. When the adjusting threaded rod 35 rotates, the two height limit plates 34 can be driven to rotate in different directions respectively under the action of the thread, thereby adjusting the distance between the two height limit plates 34, and the height of the clamped stator can be limited, which is more convenient and practical.

[0056] In a preferred embodiment, please refer to Figure 7 and Figure 8 The coil conveying assembly 4 includes a coil conveying frame 41, which is arranged on the outer side of the wire insertion platform 1, one end of the inner side of the coil conveying frame 41 is rotatably connected to the active roller 42, and the other end of the inner side of the coil conveying frame 41 is rotatably connected to the driven roller 43, one side of one end of the coil conveying frame 41 is fixed with the driven roller 43, the output end of the driven roller 43 is fixed to the active roller 42, and a conveyor belt 45 is installed on the outer side of the active roller 42 and the driven roller 43, and a fixed plate 46 is fixed to the bottom of the coil conveying frame 41, and a cylinder lifting module is installed at the bottom of the fixed plate 46.

[0057] In this embodiment, when the second motor 44 drives the active roller 42 to rotate, the conveyor belt 45 will also be driven to rotate. When the stator is located above the conveyor belt 45, the stator can be transported. At the same time, the cylinder module installed at the bottom of the fixed plate 46 can control the overall lifting and lowering of the coil conveying assembly 4, and then cooperate with the height limiting plate 34, so that the stator can be transported just between the two height limiting plates 34.

[0058] Secondly, please also refer to Fig. 9 and Fig.10 , a side plate adjustment assembly 6 is installed inside the coil conveying frame 41, and the side plate adjustment assembly 6 is used to control the sliding of the two side baffles 61. The side plate adjustment assembly 6 includes two connecting plates 62, the top of the connecting plate 62 is fixed to the side baffle 61, and one end of the connecting plate 62 is fixed with two second guide rods 63 and a threaded sleeve 64, and the second guide rod 63 and the threaded sleeve 64 are both slidably connected to the coil conveying frame 41. The side plate adjustment assembly 6 also includes a second support plate 65, and there are two second support plates 65. A support member 66 is fixed to one side of one of the second support plates 65, and one end of the support member 66 is rotatably connected to a rotating shaft 69, and a driven bevel gear 70 is fixed to the outside of the rotating shaft 69. Both ends of the rotating shaft 69 are fixed with screw rods 71, and the screw threads of the two screw rods 71 ​​are in opposite directions. The screw rod 71 is threadedly connected to the threaded sleeve 64, and a third motor 67 is fixed to one side of the other second support plate 65. An active bevel gear 68 is fixed to the output end of the third motor 67, and the active bevel gear 68 is meshed with the driven bevel gear 70.

[0059] In the above, when the side baffle 61 is controlled to translate, the active bevel gear 68 is driven to rotate by the third motor 67, and the driven bevel gear 70 and the screw rod 71 are controlled to rotate together under the meshing transmission. Since the threaded sleeve 64 is threadedly connected to the screw rod 71, the screw rod 71 will drive the threaded sleeve 64 to slide when it rotates. When the threaded sleeve 64 slides, it also drives the connecting plate 62 and the side baffle 61 connected thereto to slide, thereby enabling the side baffle 61 to translate. When the spacing between the side baffles 61 is changed, it can adapt to the use of stators of different specifications.

[0060] For further information, please also refer to Figure 7 and Figure 8 An electric loading and unloading assembly 5 is installed on the top of the coil conveying frame 41, and the electric loading and unloading assembly 5 includes two electric sliders 51. The electric sliders 51 are installed on both sides of the coil conveying frame 41. A support rod 52 is fixed on the top of the electric slider 51. A first support plate 53 is fixed between the tops of the two support rods 52. A second electric push rod 54 is fixed on the top of the first support plate 53. An electric clamp 55 is installed at the output end of the second electric push rod 54 and below the first support plate 53.

[0061] In this embodiment, the electric clamp 55 arranged below the second electric push rod 54 can clamp the stator and transport the stator to the clamping assembly 2 for clamping or remove the stator clamped by the clamping assembly 2, and the electric slider 51 controls the movement of the electric clamp 55, thereby being able to transport the clamped stator.

[0062] In a preferred embodiment, please refer to Figure 5 and Figure 6 The wiring insertion mechanism 8 also includes a support frame 81, which is fixed on the upper surface of the wiring insertion platform 1. A third electric push rod 82 is fixed on the top of the support frame 81, and a slide 83 is fixed on the output end of the third electric push rod 82. The slide 83 is slidably installed on the top of the support frame 81, and a fourth electric push rod 84 is fixed on the top of the slide 83. The output end of the fourth electric push rod 84 is fixed to the connecting plate 85.

[0063] In this embodiment, the third electric push rod 82 and the fourth electric push rod 84 are respectively used to control the coil set below to move horizontally and vertically, thereby making it more convenient to insert the wires into the coil.

[0064] Example 2, please refer to the attached Fig.11 As shown, it is a second embodiment of the present invention, which is based on embodiment 1 and provides a coil assembly automatic wire insertion process, including the following steps:

[0065] Step 1: Insert the insulating paper into the stator slot to isolate the conductors of different phases and the conductors from the stator core to ensure insulation performance.

[0066] Step 2: transport the stator, transfer the stator with the inserted insulating paper to the coil transport component 4 and transport it to the wire insertion area;

[0067] Step 3: Insert the coil. Install the prepared coil into the wire insertion mechanism 8. Insert the coil into the stator slot of the stator under the guidance of the wire insertion mechanism 8. After the coil is inserted, withdraw the wire insertion mechanism 8 and reinstall the coil.

[0068] Step 4: Adjust the stator. After one coil is inserted, control the stator to rotate through the clamping assembly 2, move the remaining stator slots to correspond to the insertion mechanism 8, continue to insert the coil, and repeat until all coils are inserted;

[0069] Step 5: Finished product return: the stator with completed wire insertion is removed from the clamping assembly 2 by the electric loading and unloading assembly 5 on another coil conveying assembly 4 and sent to the coil conveying assembly 4 for conveying to the next assembly line.

[0070] The working principle of the present invention is as follows: the stator after the insulating paper is inserted is transported to a position close to the clamping assembly 2 by the coil conveying assembly 4. At this time, the stator is clamped by the electric clamp 55 and pushed toward the clamping assembly 2. The clamping assembly 2 is squeezed and contracted, so that the stator enters between the three clamping assemblies 2, and is clamped and positioned by the clamping assembly 2. After that, the coil is inserted into the wire insertion mechanism 8, and the first wire support rod 87 is pushed down by the fifth electric push rod 86, so that the coil between the first wire support rod 87 and the second wire support rod 88 is tightened, and then the coil is controlled to descend. Insert the coil between the stator slots and align it with the stator slots through the lead spring piece 89, so as to ensure the alignment of the coil with the stator slots, thereby ensuring the accuracy of the wire insertion. Then withdraw the wire insertion mechanism 8 and re-install the coil, and drive the stator to rotate by controlling the rotating clamp 33 to re-adjust the stator slot and the coil on the wire insertion mechanism 8, and insert the coil again. When the coil is fully inserted, remove the stator between the clamping components 2 through the electric loading and unloading component 5 provided on the coil conveying component 4, and re-install the stator that has not been inserted through another coil conveying component 4 for wire insertion.

[0071] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
