By switching positions between different wire embedding molds by one servo motor, the time for replacing the wire embedding molds can be saved, the efficiency can be improved, and at the same time, the number of servo motors is reduced, thereby reducing the cost.

[0004] To solve the above technical problems, the utility model is realized by the following technical solutions: A driving mechanism includes a servo motor and a servo motor moving mechanism installed on a first side plate. The servo motor drives a wire embedding mold through a transmission mechanism, and the servo motor moving mechanism drives the servo motor to switch positions among multiple wire embedding molds.

[0005] As a preferred solution, the transmission mechanism includes a transmission lead screw, a main push transition wheel and a driven pulley connected by a synchronous belt.

[0008] On the other hand, the utility model further provides a stator wire embedding device, including the driving mechanism as described above.

[0009] As a preferred solution, it further includes a pressing arm mechanism and a mechanical arm locking mechanism. A set of pressing arm mechanisms are arranged on both sides of each wire embedding mold. The pressing arm mechanism includes a pressing arm cylinder and a mechanical arm. One end of the mechanical arm is connected to the pressing arm cylinder, and a pressing arm is installed at the other end of the mechanical arm.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] It should be noted that the terms used here are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0024] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present utility model; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0026] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings of the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0027] In addition, it should be noted that the use of words such as "first", "second" to limit components is only for the convenience of differentiating the corresponding components. Without additional statement, the above words have no special meaning, and thus should not be construed as limiting the protection scope of the present utility model.

[0029] As shown in Figures 1 to 3 Figure , a driving mechanism includes a servo motor 1. The servo motor 1 drives an inlay die 2 through a transmission mechanism 3. It further includes a servo motor moving mechanism 4 installed on a first side plate 61. The servo motor moving mechanism 4 drives the servo motor 1 to change positions among multiple inlay dies 2, which can save the time for changing the inlay die, improve efficiency. At the same time, the number of servo motors is also reduced, thereby reducing the cost.

[0030] In one embodiment, the transmission mechanism 3 includes a transmission lead screw 35, a main drive transition wheel 31 and a driven pulley 32 connected by a synchronous belt 33. The main drive transition wheel 31 is connected to the drive shaft of the servo motor 1 through a main drive force wheel 34. The side of the main drive transition wheel 31 for installing the main drive force wheel 34 has an installation groove 311. Both sides of the installation groove 311 along the advancing direction of the servo motor 1 have avoidance openings 312, so as to facilitate the main drive force wheel 34 to enter and exit the installation groove 311 when the servo motor 1 moves horizontally. Among them, the structure of the main drive force wheel 34 is as shown in Figure 3 Figure ; one end of the transmission lead screw 35 is connected to the driven pulley 32 through a rotating seat 36, and the other end is connected to the inlay die 2. In addition, a synchronous belt tensioning wheel mechanism 37 is arranged below the synchronous belt 33 for tensioning the synchronous belt 33.

[0031] In one embodiment, the servo motor moving mechanism 4 includes a side push cylinder 41 and a linear guide rail 42. The servo motor 1 is slidably installed on the linear guide rail 42 through a motor plate 11 and a slider. The side push cylinder 41 pushes the motor plate 11 to slide on the linear guide rail 42, so that the servo motor 1 slides along the linear guide rail 42, moving from one inlay die 2 to another inlay die 2, realizing the switching between different inlay dies 2.

[0032] In one embodiment, in order to improve the stability of the servo motor 1 after position change, the driving mechanism further includes a motor fixing mechanism 5. The motor fixing mechanism 5 includes a pin cylinder 51 and a pin seat 52. The pin cylinder 51 is fixed to the first side plate 61 through a pin cylinder seat 53. An L-shaped plate 54 is installed on one side of the pin cylinder seat 53. If the servo motor 1 moves to the left, the L-shaped plate 54 is installed on the right side of the pin cylinder seat 53 to prevent interference when the servo motor 1 moves. During work, the pin cylinder 51 passes through the holes in the pin seat 52, the motor plate 11, and the L-shaped plate 54 in sequence to achieve fixation.

[0033] Embodiment 2

[0034] As shown in Figures 1 - 7 Figure , a stator inlay device includes the driving mechanism in Embodiment 1. In addition, it further includes an electric control cabinet 9 and a stator placement table 10.

The pressing arm mechanism 7 includes a pressing arm cylinder 71 and a robotic arm 72. The robotic arm 72 passes through the first side plate 61 and the second side plate 62. The pressing arm cylinder 71 is installed on the first side plate 61. One end of the robotic arm 72 is connected to the pressing arm cylinder 71, and a pressing arm 73 is installed at the other end of the robotic arm 72. The pressing arm 73 is used to press the stator. One side of the robotic arm 72 close to the pressing arm cylinder 71 is locked by a robotic arm locking mechanism 8. Specifically, the robotic arm locking mechanism 8 includes a locking cylinder 81, a first locking plate 82, and a second locking plate 83. The locking cylinder 81 is connected to the second locking plate 83 through a T-shaped first locking plate 82. The second locking plate 83 is provided with a first locking hole 831 and a second locking hole 832 that are connected. The robotic arm 72 passes through the first locking hole 831 and the second locking hole 832. Among them, the aperture of the first locking hole 831 is larger than that of the second locking hole 832. When the pressing arm cylinder 71 drives the robotic arm 72 to rotate to the required position, the second locking plate 83 is pushed by the locking cylinder 81, so that the second locking hole 832 with a small aperture contacts the robotic arm 72, thus playing a locking role. During use, the stator is placed on the stator placement table 10. The pressing arm cylinder 71 drives the robotic arm 72, so that the pressing arm 73 rotates. The two pressing arms 73 of each group rotate to form an inverted V shape to press the stator tightly, and then it is locked by the robotic arm locking mechanism 8.

[0036] In one embodiment, the wire embedding mold 2 includes a paper storage bin, a paper forming mechanism, a paper pushing mechanism, a stacking thickness mechanism 21, and a wire embedding mold head. The wire embedding mold head is connected to the transmission mechanism 3 through a transmission lead screw 35. Specifically, one end of the transmission lead screw 35 is connected to the driven pulley 32 of the transmission mechanism 3 through a rotating seat 36, and the other end of the transmission lead screw 35 is connected to the wire embedding mold head. Then, driven by the servo motor 1, the rotating seat 36 is driven to rotate, so that the transmission lead screw 35 makes a linear motion, thereby pushing the sliding plate 214 to make a linear motion along the guide post 216. The subsequent working principle, as well as the specific structures and working principles of the paper storage bin, the paper forming mechanism, and the wire embedding mold head, have been disclosed in the previous applications of the company, such as CN106602813A and CN117543921A, and will not be elaborated here. Among them, as Figure 7As shown in the figure, the stacking thickness mechanism 21 includes a stacking thickness motor 211, a synchronous pulley assembly 212, and a lead screw 213. The stacking thickness motor 211 is installed on the sliding plate 214 through a stacking thickness motor mounting plate. Both sides of the sliding plate 214 are installed on the guiding column 216 through linear bearings. And on one side of the sliding plate 214 close to the stacking thickness motor 211, a stacking thickness guiding column 217 is installed through a linear bearing. The linear bearing is also connected to the lead screw fixing plate 215. The stacking thickness motor 211 drives the lead screw 213 to rotate through the synchronous pulley assembly 212. The lead screw 213 is installed on the lead screw fixing plate 215 through a nut, thereby driving the lead screw fixing plate 215, the sliding plate 214, and the stacking thickness guiding column 217 thereon to perform linear motion, so as to adapt to stators with different stacking sheet heights.
