They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0038] Reference Figures 1 to 4 This application provides a stator assembly machine, including a work platform 10, a conveyor belt 20 disposed on the work platform 10, a stator core feeding mechanism 30, a lower frame feeding mechanism 40, a core flipping mechanism 50, an upper frame feeding mechanism 60 arranged sequentially along one side of the conveyor belt 20, and two pressing mechanisms 70 disposed above the conveyor belt 20 and corresponding to the lower frame feeding mechanism 40 and the upper frame feeding mechanism 60, respectively. In this embodiment, the stator core 1 is conveyed onto the conveyor belt 20 by the stator core feeding mechanism 30, the lower frame feeding mechanism 40 conveys the lower frame 2 onto the stator core 1 on the conveyor belt 20, the lower frame 2 is installed onto the stator core 1 by a pressing mechanism 70, the stator core 1 is flipped by the core flipping mechanism 50, the lower frame feeding mechanism 60 conveys the upper frame 3 onto the flipped stator core 1, and the upper frame 3 is installed onto the stator core 1 by another pressing mechanism 70, thereby realizing the assembly of the stator.

[0039] Reference Figure 5The stator core feeding mechanism 30 includes a first rotating mechanism 31, multiple feed rods 32 mounted on the first rotating mechanism 31 for mounting stator cores 1 after stacking, and a first picking mechanism 33 located on one side of the first rotating mechanism 31 for picking up stator cores 1 from the feed rods 32 and transferring them to the conveyor belt 20. During feeding, multiple stator cores 1 are threaded onto the feed rods 32, and the first picking mechanism 33 picks up the stator cores 1 from each feed rod 32 sequentially. After all the stator cores 1 on a feed rod 32 have been picked up, the first rotating mechanism 31 rotates at a certain angle so that the next feed rod 32 faces the first picking mechanism 33, and the first picking mechanism 33 continues to pick up the stator cores 1 from this feed rod 32, and so on, until all the stator cores 1 on all feed rods 32 have been picked up. This feeding structure, using a rotating mechanism in conjunction with the feed rods 32, allows for the feeding of a large number of stator cores 1 at a time, improving operational efficiency.

[0040] Furthermore, the stator core feeding mechanism 30 also includes a first lifting mechanism 34 located on one side of the first rotating mechanism 31, capable of driving the first rotating mechanism 31 to move up and down. Since the stator core 1 is stacked on the feed rod 32, as the stator core 1 is continuously picked up, the height of the stator core 1 on the feed rod 32 gradually decreases. In this embodiment, the first picking mechanism 33 can only move horizontally and cannot move up and down. Therefore, the first lifting mechanism 34 drives the entire first rotating mechanism 31, the feed rod 32, and the stator core 1 located on it to move upwards together to cooperate with the picking by the first picking mechanism 33. Of course, the first picking mechanism 33 can also be configured to move up and down, thus omitting the first lifting mechanism 34.

[0041] Specifically, in this embodiment, the first rotating mechanism 31 includes a vertically arranged first rotating motor 311 and a first rotating disk 312 driven by the output shaft of the first rotating motor 311, with multiple feed rods 32 evenly arranged along the first rotating disk 312. In this way, multiple feed rods 32 can be arranged along the first rotating disk 312, thereby increasing the number of stator cores 1 that can be fed.

[0042] In this embodiment, a second rotating mechanism 35 for correcting the position of the stator core 1 is provided between the first rotating mechanism 31 and the conveyor belt 20. A sensor (not labeled in the figure) for sensing notches on the stator core 1 is provided on one side of the second rotating mechanism 35. Multiple notches are evenly distributed on the stator core 1. To facilitate precise alignment and assembly of the stator core 1 with the lower frame 2 and upper frame 3, the stator core 1 needs to be placed at a predetermined angle on the conveyor belt 20. However, when the stator core 1 is manually placed on the material bar 32, it is placed randomly. Therefore, its position needs to be corrected before being placed on the conveyor belt 20 to achieve the predetermined angle. The first picking mechanism 33 picks up the stator core 1 from the material bar 32 and places it on the second rotating mechanism 35. When the sensor does not detect a notch in the stator core 1, the second rotating mechanism 35 rotates it by a certain angle until the sensor detects the notch.

[0043] Furthermore, a marking device 36 is provided on one side of the second rotating mechanism 35. The marking device 36 marks the stator core 1 with relevant production information. Of course, for some stator cores 1, the marking operation has been completed before loading, so the marking device can be omitted here.

[0044] In this embodiment, the first picking mechanism 33 includes a first horizontal track 331 and two first robotic arms 332 spaced apart on the first horizontal track 331. Thus, when moving horizontally along the first horizontal track 331, the two first robotic arms 332 can simultaneously complete operations at three stations. For example, when the first first robotic arm 332 picks up the stator core 1 from the feed rod 32, the second first robotic arm 332 picks up the stator core 1 that has been calibrated on the second rotating mechanism 35. After horizontal movement, the first first robotic arm 332 places the stator core 1 picked up from the feed rod 32 onto the second rotating mechanism 35 for calibration, while the second first robotic arm 332 places the calibrated stator core 1 onto the carrier 21 of the conveyor belt 20. That is, the first first robotic arm 332 reciprocates between the feed rod 32 and the second rotating mechanism 35, while the second first robotic arm 332 reciprocates between the second rotating mechanism 35 and the carrier 21 of the conveyor belt 20. In this way, two first robotic arms 332 can be driven simultaneously to perform picking operations through a single horizontal drive device. The structure is simple, there will be no idle standby, and the production efficiency is higher.

[0045] In this embodiment, the lower frame feeding mechanism 40 and the lower frame feeding mechanism 60 differ only in the objects they feed: the lower frame 2 and the upper frame 3, respectively. The structures of the lower frame feeding mechanism 40 and the lower frame feeding mechanism 60 are identical. Here, the structure of the lower frame feeding mechanism 40 is described in detail.

[0046] Specifically, the lower frame feeding mechanism 40 includes a vibratory feeder 41 for feeding materials and a second picking mechanism 42 for picking up the lower frame 2 from the outlet of the vibratory feeder 41. Since the lower frame 2 is relatively lightweight, multiple lower frames 2 can be manually placed on the vibratory feeder 41, and then the lower frames 2 can be conveyed forward one by one by the vibration of the vibratory feeder 41.

[0047] Furthermore, the lower frame feeding mechanism 40 also includes a detection sensor 43 located at the outlet of the vibratory feeder 41 for detecting the lower frame 2. The detection sensor 43 includes a transmitter and a receiver arranged opposite each other, mainly used to sense whether there is a lower frame 2 at the vibratory feeder 41, i.e., to detect whether there is material present or absent. When there is no lower frame 2 at the outlet of the vibratory feeder 41, there is no lower frame 2 obstructing the transmitter and receiver, and they can complete signal reception. At this time, it reminds the operator to add the lower frame 2 into the vibratory feeder 41. When there is a lower frame 2 obstructing the transmitter and receiver, they cannot complete signal reception, indicating that there is a lower frame 2 present, and no feeding operation is required.

[0048] Furthermore, in this embodiment, the lower frame loading mechanism 40 also includes a third rotating mechanism 44 disposed between the vibratory feeder 41 and the conveyor belt 20, and a visual inspection device (not shown in the figure) disposed above the third rotating mechanism 44 for taking pictures of the lower frame 2. Similarly, the lower frame 2 also has multiple notches. When assembling it to the stator core 1, it needs to be aligned with the stator core 1. Therefore, the lower frame 2 also needs to be corrected to achieve the preset placement angle. After the lower frame 2 is picked up from the vibratory feeder 41 by the second picking device and placed on the third rotating mechanism 44, the visual inspection device takes pictures of it. When the position of the lower frame 2 is inconsistent with the preset position, the third rotating mechanism 44 drives it to rotate to the preset position.

[0049] Similarly, in this embodiment, the second picking mechanism 42 also includes a second horizontal track 421 and two second robotic arms 422 spaced apart on the second horizontal track 421. When moving horizontally along the second horizontal track 421, the two second robotic arms 422 simultaneously complete operations at three stations. For example, when the first second robotic arm 422 picks up the lower frame 2 from the vibratory feeder 41, the second second robotic arm 422 picks up the lower frame 2 that has been calibrated on the third rotating mechanism 44. After horizontal movement, the first second robotic arm 422 places the lower frame 2 picked up from the vibratory feeder 41 onto the third rotating mechanism 44 for calibration, while the second second robotic arm 422 places the calibrated lower frame 2 onto the stator core 1 of the carrier 21 of the conveyor belt 20. That is, the first second robotic arm 422 reciprocates between the vibratory feeder 41 and the third rotating mechanism 44, while the second second robotic arm 422 reciprocates between the third rotating mechanism 44 and the stator core 1 of the carrier 21 of the conveyor belt 20. In this way, two second robotic arms 422 can be driven simultaneously by a single horizontal drive device to perform picking operations. The structure is simple, there will be no idle standby, the production efficiency is higher, and it can also maintain the same feeding efficiency as the stator core feeding mechanism 30 and the lower frame feeding mechanism 60, making the work between the mechanisms more coordinated.

[0050] In this embodiment, after the lower frame 2 is placed on the stator core 1 on the conveyor belt 20 by the second robotic arm 422 on the second picking mechanism 42, the lower frame 2 is installed on the top of the stator core 1 by the pressing mechanism 70. Specifically, refer to Figure 4 and Figure 6 The pressing mechanism 70 includes a support platform 71 located above the conveyor belt 20, multiple movable support assemblies 72 located around the support platform 71, and a slide assembly 73 located on the second picking mechanism 42. The support platform 71 is a hollow cylinder, and its sidewalls have notches for the multiple movable support assemblies 72 to extend into and support the lower frame 2 or the upper frame 3, respectively. A lifting mechanism (not shown in the figure) is located below the conveyor belt 20 for lifting the stator core 1 into the support platform 71. The second robot arm 422 is located on the slide assembly 73.

[0051] Reference Figure 6 In this embodiment, the multiple movable support components 72 have the same structure, and their number corresponds to the number of notches on the lower frame 2. Each movable support component 72 includes a cylinder 721 and a support block (not shown in the figure) disposed on the piston rod of the cylinder 721. The width of the support block matches the notches on the lower frame 2. The second robot arm 422 is disposed on the slide assembly 73.

[0052] When installing the lower frame 2, the second robotic arm 422 first moves it to the top of the support platform 71 via the third rotating mechanism 44. At this time, the lifting mechanism also lifts the stator core 1 on the carrier 21 so that it enters the support platform 71 and is separated from the conveyor belt. When the slide assembly 73 drives the lower frame 2 to the position of contact with the stator core 1, the cylinder 721 drives the support block to extend into the notch of the lower frame 2, opening the notch so that it can be inserted into the stator core 1 when the slide assembly 73 continues to drive it to move down.

[0053] Reference Figure 7 After the lower frame 2 is installed on the stator core 1, the stator core 1 needs to be rotated vertically before installing the upper frame 3. This process is achieved by the core flipping mechanism 50. The core flipping mechanism 50 includes a horizontally positioned second rotary motor 51 and a gripper 52 on the output shaft of the second rotary motor 51 for picking up the stator core 1. The second rotary motor 51 is horizontally positioned. After the gripper 52 picks up the stator core 1, the output shaft of the second rotary motor 51 rotates 180 degrees, and the stator core 1 is rotated vertically and then placed on the carrier 21. It is then moved forward to a position directly opposite the lower frame loading mechanism 60 for the installation of the upper frame 3.

[0054] The structure of the lower frame feeding mechanism 60 is the same as that of the lower frame feeding mechanism 40, and the installation steps are also exactly the same, so they will not be described again here.

[0055] In this embodiment, the stator assembly machine also includes an inspection station 80 located on the conveyor belt 20. After the stator core 1 completes the installation of the lower frame 2 and the upper frame 3, it continues to move forward along the conveyor belt 20 to the inspection station 80. The inspection device on the inspection station 80 checks whether the installation of the lower frame 2 and the upper frame 3 is qualified. If it is not qualified, it is picked up by the third picking device 90 and taken away manually in the unqualified area. If it is qualified, the third picking device 90 picks it up and returns it to another conveyor belt 20 to the designated position. The fourth picking device (not shown in the figure) takes away the assembled semi-finished product, and the carrier 21 is transferred to the original conveyor belt 20 to provide support for the stator core 1 to be fed by the stator core feeding mechanism 30 in the next cycle.

[0056] In this application, the stator core is assembled using the above-mentioned structure, which results in high efficiency in the cooperation of each part, and the structure is simple and easy to use.

[0057] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
