Description

Technical Field

[0001] The present application relates to the technical field of stator coil installation production equipment, and in particular to a stator coil installation production line. Background Art

[0002] In the field of stator coil installation and production equipment, with the increasing demand for industrial automation, the efficiency and quality of stator coil installation are receiving increasing attention. Efficient stator coil installation technology can significantly improve the production scale and quality of motors and other related products, and is of great significance for the development of the entire motor industry and numerous other industries that rely on motor drives. A sound stator coil installation method can help improve motor performance stability, reduce the probability of failure, and thus ensure the normal operation of various types of mechanical equipment. Furthermore, improved production efficiency can effectively reduce production costs and enhance a company's market competitiveness. Currently, the relevant technology for stator coil installation and production mainly relies on traditional manual operation. Typically, the stator coil is placed on a fixed workbench, and a single operator, working on the same workbench, sequentially completes the entire stator coil installation process on the stator. These steps include shaping the exposed coil ends at both ends of the stator, tying the ends with cloth strips, arranging and shaping the leads at the ends, welding the leads, and wrapping the ends with cloth strips. This operation method requires workers to manually complete each step and frequently adjust the position and configuration of the stator coil within a limited space. However, this existing technology has significant drawbacks. Because all steps are manually completed one by one, workers must maintain high-intensity labor for long periods of time, resulting in extremely high labor intensity. Furthermore, manual operation is relatively slow and easily affected by factors such as fatigue and mood, resulting in low work efficiency and difficulty meeting the needs of large-scale production. Therefore, a new stator coil installation device is urgently needed to improve production efficiency and reduce labor intensity. Summary of the Invention

The lifting mechanism drives the turnover plate and the stator coil to rise to the turning mechanism position. The turning mechanism clamps and rotates the stator coil to turn. After the stator coil turns, the lifting mechanism drives the turnover plate to rise and continue to support the stator coil after the turn, and lands on the turning conveying mechanism.

[0040] The following combination Figures 1 to 17 This application is described in further detail.

[0041] The embodiment of the present application discloses a stator coil installation production line.

[0042] A stator coil installation production line. Figure 1 and Figure 2, including several turnover plates 1, a loading device 2, a first conveying device 3, a turning device 4, a second conveying device 5, a third conveying device 6, a unloading device 7 and a transfer device 8. The stator coil 9 is vertically supported on the turnover plate 1 during the installation and production process to facilitate movement on the production line and to facilitate the installation of the coil located at the upper end of the stator coil 9. The loading device 2 is used to flip the stator coil 9 to be installed from a horizontal state to a vertical state, so that the stator coil 9 stands upright on the turnover plate 1 with the tail at the upper end. The first conveying device 3 is used to turn the stator coil 9 from a horizontal state to a vertical state, so that the stator coil 9 stands upright on the turnover plate 1 with the tail at the upper end. One end is connected to the feeding device 2, and the other end is connected to the second conveying device 5. The turning device 4 is connected to the first conveying device 3 and is located at one end of the first conveying device 3 close to the second conveying device 5. The tail of the stator coil 9 is installed on the first conveying device 3 within the distance between the feeding device 2 and the turning device 4. After the installation of the tail of the stator coil 9 is completed, the stator coil 9 is moved to the turning device 4 to turn the stator coil 9 so that the head of the stator coil 9 is located at the upper end and returned to the first conveying device 3. The second conveying device The device 5 is arranged perpendicular to the first conveying device 3, the third conveying device 6 is arranged parallel to the first conveying device 3, the end of the second conveying device 5 away from the first conveying device 3 is connected to the third conveying device 6, and the end of the third conveying device 6 away from the second conveying device 5 is connected to the unloading device 7. The two ends of the transfer device 8 are connected to the first conveying device 3 and the third conveying device 6. During the movement of the second conveying device 5 and the third conveying device 6, the stator coil 9 is installed on the head coil located at the upper end of the stator coil 9. After the installation is completed, the stator coil 9 enters the unloading device 7 from the third conveying device 6 for unloading of the stator coil 9. After unloading from the unloading device 7, the turnover disk 1 returns to the third conveying device 6, returns to the first conveying device 3 through the transfer device 8, and then moves from the first conveying device 3 to the loading device 2 for loading the stator coil 9, so that the turnover disk 1 can be circulated and used on the production line. It should be noted that the structure of the unloading device 7 is the same as that of the loading device 2. The various devices work together to improve the production efficiency of the stator coil 9 installation and reduce the labor intensity of the workers.

[0043] Reference Figure 2The turnover plate 1 includes a turnover plate 11, a support ring 12 and a handle 13. The turnover plate 11 of the embodiment of the present application is a square steel plate. Weight reduction holes 15 can be set on the steel plate. The steel plate is also provided with positioning holes 14 for positioning the turnover plate 1 when the stator coil 9 is installed. The embodiment of the present application has two positioning holes 14, and can also be other numbers of positioning holes 14, as long as they can meet the positioning requirements. The support ring 12 is fixed to the upper side of the turnover plate 11 by screws. The support ring 12 can be replaced according to the stator diameter of different specifications. A handle 13 is installed on the turnover plate 11 outside the support ring 12. The number of handles 13 in the embodiment of the present application is two, and the two handles 13 are respectively located on two adjacent sides of the turnover plate 11, which is convenient for grasping handles in different positions. 13 can move the turnover plate 11 in two mutually perpendicular directions, and the support ring 12 can support the end face of the stator, so that the stator coil 9 can be stably placed on the turnover plate 1, and at the same time, the coils at both ends of the stator are located in the support ring 12, which helps to protect the coils supported in the support ring 12. The handle 13 is convenient for pushing and pulling the turnover plate 1, which is beneficial for the turnover plate 1 to move and circulate on the production line, and is convenient for the stator coil 9 to be installed and produced at different stations on the production line. Through the cooperation of the turnover plate 1 with the loading device 2, the first conveying device 3 to the third conveying device 6, the turning device 4, the unloading device 7 and the transfer device 8, the installation and production of the stator coil 9 are realized in each station in sequence, which improves the production efficiency of the stator coil 9 installation and reduces the labor intensity of the workers.

[0044] Reference Figures 3 to 5 The feeding device 2 includes a feeding frame 21, a turning frame 22 and a turning drive assembly 23. The turning frame 22 is rotatably arranged on the feeding frame 21. The turning drive assembly 23 is installed on the feeding frame 21 and can drive the turning frame 22 to rotate. The sliding support assembly 24 for horizontally supporting the stator coil 9 and the rolling support assembly 25 for supporting the turnover plate 1 in a horizontal position are installed on the turning frame 22. When the sliding support assembly 24 is in a horizontal position, the stator coil 9 with an axial direction horizontal is placed on the sliding support assembly 24. When the turning frame 22 is rotated to make the sliding support assembly 24 in a vertical position, the stator coil 9 is turned over to be axially vertically supported on the rolling support assembly 25 on the turnover disk 1; when the stator coil 9 is loaded, the stator coil 9 is horizontally hoisted and placed on the sliding support assembly 24, and the turnover disk 1 stands vertically on the side of the rolling support assembly 25 close to the sliding support assembly 24, and the flip drive assembly 23 drives the flip frame 22 to rotate. When the sliding support assembly 24 is in a vertical position, the stator coil 9 is flipped to be axially vertically supported on the turnover disk 1 on the rolling support assembly 25. The turnover disk 1 can be moved to the first conveying device 3 through the rolling support assembly 25, which is convenient for the subsequent installation and production operations of the stator coil 9 on the turnover disk 1, thereby improving the working efficiency of loading the stator coil 9 and reducing the labor intensity of workers.

[0045] Reference Figure 3 and Figure 4 The turning frame 22 includes a sliding bracket 221 and a rolling bracket 222 arranged perpendicular to each other. A turning shaft 223 is provided at the connection portion of the sliding bracket 221 and the rolling bracket 222. The turning shaft 223 is fixedly connected to the sliding bracket 221 and the rolling bracket 222. Both ends of the turning shaft 223 are rotatably supported on the loading rack 21 through bearing seats. One end of the turning shaft 223 extends out of the loading rack 21 and is transmission-connected to the turning drive assembly 23. A sliding support assembly 24 is installed on the sliding bracket 221, and a rolling support assembly 25 is installed on the rolling bracket 222. The loading rack 21 is also provided with a first limiting member 211 and a second limiting member 212 for respectively limiting the turning of the sliding bracket 221 and the rolling bracket 222. When the sliding bracket 221 is in a horizontal position, the first limit member 211 supports the end of the sliding bracket 221 away from the flipping axis 223. When the rolling bracket 222 is in a horizontal position after flipping, the second limit member 212 supports the end of the rolling bracket 222 away from the flipping axis 223. Through the support of the first limit member 211 and the second limit member 212, the position stability of the sliding support assembly 24 and the rolling support assembly 25 can be ensured before and after flipping. This design not only ensures the precise positioning and reliable support of the sliding support assembly 24 and the rolling support assembly 25 for the stator coil 9 during the flipping process, but also effectively improves the stability of the device during the flipping process and the high efficiency of loading the stator coil 9.

[0046] Reference Figure 4 The turning drive assembly 23 includes a turning motor 231, a small sprocket 232, a large sprocket 233 and a turning chain 234. The turning motor 231 is fixedly mounted on the loading frame 21, and the small sprocket 232 is fixedly mounted on the output shaft of the turning motor 231. The large sprocket 233 is fixedly mounted on the end of the turning shaft 223 extending out of the loading frame 21. The large sprocket 233 and the small sprocket 232 are connected by the turning chain 234 for transmission. The turning motor 231 drives the small sprocket 232 to rotate, and the small sprocket 232 drives the large sprocket 233 to rotate through the turning chain 234, so that there is a large transmission ratio between the small sprocket 232 and the large sprocket 233, which can reduce the speed of the turning shaft 223. This transmission method can stably transmit the power of the turning motor 231 to the turning shaft 223, ensuring that the turning frame 22 rotates smoothly and accurately, thereby successfully completing the turning operation of the stator coil 9 from the horizontal to the vertical state.

A linear guide pair is provided between the base frame 81 and the transfer frame 82. The linear guide pair in the embodiment of the application is a linear guide and a slider. The linear guide is slidably connected to the slider. The linear guide is fixedly installed on the base frame 81, and the slider is fixedly connected to the transfer frame 82. The transfer support assembly 83 is fixedly installed on the transfer frame 82, which can support several turnover plates 1. The embodiment of the application can support 3 turnover plates 1, and other embodiments can It can support 4 or 5 turnover plates 1. Two clamping components 84 are respectively installed on the transfer frame 82, which can clamp the outermost turnover plate 1 to prevent the turnover plate 1 from detaching from the transfer support component 83 during the transfer process. The transfer drive mechanism 85 drives the transfer frame 82 to move back and forth on the base frame 81. The sliding connection between the base frame 81 and the transfer frame 82 realizes the reciprocating movement of the transfer frame 82. The transfer support component 83 can firmly support multiple turnover plates 1. The clamping component 84 effectively prevents the outermost turnover plate 1 from being displaced during the movement.
