[0020] The following is combined with Figure 1-3 This application is described in further detail.
[0021] A stator core side marking device, such as Figure 1 As shown, it includes a body 1, a rotating table 2 is arranged on the body 1, and a positioning member for positioning the stator core 4 is arranged on the rotating table 2. The positioning member includes a positioning column 3 vertically fixed on the rotating table 2. There are multiple positioning columns 3 evenly distributed around the circumference. The top of the positioning column 3 is conical. The positioning column 3 is used to adapt to the perforation on the outer peripheral lug of the stator core 4. The stator core 4 is placed on the rotating table 2 for positioning. The conical setting of the top of the positioning column 3 facilitates the placement operation of the stator core 4, and a driving member for driving the stator core 4 to rotate is arranged on the body 1. The driving member can be a rotating cylinder or a rotating motor. In actual use, the circumferential orientation of the stator core 4 is adjusted by rotating the rotating table 2.
[0022] like Figure 1 As shown, a mounting column 5 is fixedly provided on one side of the body 1, and a mounting box 6 is vertically adjustable on the mounting column 5. The mounting box 6 is cylindrical, and a laser generator 9 is provided on the mounting box 6. The lens of the laser generator 9 is horizontally facing the center direction of the rotating table 2. A QR code mark can be printed on the side of the stator core 4 through the laser generator 9. The QR code mark can be used to trace the initial production information and production batch of the stator core 4. In actual use, the height and angle of the mounting box 6 can be adjusted as needed to achieve the direction and height of the laser generator 9, which can ultimately meet the needs of more usage occasions and have better applicability.
[0023] In this way, laser coding is achieved on the side of the stator core 4, and the formed two-dimensional code is integrated with the stator core 4, which has better stability. The production batch and production-related information of the stator core 4 can be well traced back through the two-dimensional code.
[0024] like Figure 1 As shown, one side of the mounting box 6 has a mounting portion 10 that is sleeved on the mounting column 5. The mounting portion 10 can be vertically slidably connected to the mounting column 5, and a clamping groove 11 is opened on one side of the mounting portion 10. The mounting portion 10 can be clamped on the mounting column 5 through the clamping groove 11 to achieve fixation. The end of the mounting portion 10 is provided with a tightening bolt 12 and a tightening nut 13 corresponding to the clamping groove 11. The tightening bolt 12 is tightened to achieve fixation, so that the mounting portion 10 is movably and adjustably connected to the mounting column 5. After loosening the tightening nut 13, the vertical sliding height of the mounting box 6 can be adjusted, and the angle can also be adjusted by circumferential rotation. After adjusting to the corresponding position, tightening the tightening nut 13 can achieve positioning and fixation.
[0025] like Figure 1 and Figure 2 As shown, the installation box 6 includes an outer cylinder 7 and an inner core 8. The inner core 8 is rotatably connected in the outer cylinder 7. The laser generator 9 is embedded in the side wall of the inner core 8. At the same time, a through groove 14 is opened on the side wall of the outer cylinder 7 for exposing the lens of the laser generator 9. When the lens of the laser generator 9 corresponds to the through groove 14, the emitted laser can mark the side wall of the stator core 4. When not in use, the inner core 8 can be rotated to make the lens of the laser generator 9 misaligned with the through groove 14, so as to realize the storage of the laser generator 9 and provide good storage and protection for the lens of the laser generator 9.
[0026] like Figure 1 and Figure 2 As shown, a driving source for driving the inner core 8 to rotate is provided at the bottom of the outer cylinder 7, and the driving source includes a driving motor 15. The inner core 8 is fixed at the output end of the driving motor 15, and the position of the laser generator 9 is adjusted by driving the inner core 8 to rotate by the driving motor 15; in addition, a blowing component 16 is embedded on the side wall of the inner core 8, and the blowing component 16 can specifically be a hair dryer, so that when the inner core 8 is rotated for adjustment, when the blowing component 16 is rotated to correspond to the through slot 14, the blowing component 16 can blow and clean the side of the stator core 4 to remove impurities or dust remaining on the surface of the stator core 4. The blowing component 16 can be cleaned before or after marking, which ultimately ensures that the quality of marking is more guaranteed and saves the cleaning link in the process.
[0027] like Figure 1 and Figure 2As shown, a wiping portion 17 for wiping the lens of the laser generator 9 is embedded on the inner wall of the outer cylinder 7. The wiping portion 17 can specifically be a sponge strip. The wiping portion 17 is located on the side of the laser generator 9 that is away from the blowing assembly 16. In actual use, when the blowing assembly 16 corresponds to the through groove 14, the lens of the laser generator 9 corresponds to the wiping portion 17. In this way, when the inner core 8 is driven to switch between the laser generator 9 and the blowing assembly 16, the lens on the laser generator 9 can be cleaned and wiped synchronously, avoiding the situation where impurities adhere to the lens for a long time and affect the final marking effect, and realizing automatic cleaning of the lens on the laser generator 9, and the cleaning is simple and convenient.
[0028] like Figure 2 and Figure 3 As shown, a plurality of blowing nozzles 18 are arranged on the top wall of the through slot 14, and the blowing nozzles 18 are arranged toward the inner core 8. A wind cavity 19 is opened on the inner wall of the outer tube 7. When the laser generator 9 and the through slot 14 are in corresponding positions, the blowing assembly 16 corresponds to the wind cavity 19, and the blowing nozzle 18 is connected to the wind cavity 19, and the wind cavity 19 provides an air source to the blowing nozzle 18; in this way, when the lens of the laser generator 9 corresponds to the through slot 14, the blowing nozzle 18 can blow air to clean the surface of the lens, so as to realize the cleaning of the lens surface when the laser generator 9 is in use, and add another cleaning method for the lens on the laser generator 9.
[0029] like Figure 2 and Figure 3 As shown, the bottom wall of the through groove 14 has an arc-shaped guide surface 20 facing outward, and a dust box 21 is provided at the bottom end of the outer tube 7 corresponding to the guide surface 20. The dust box 21 is horizontally slidably connected to the outer tube 7. The dust box 21 is used to receive the blown-off dust and impurities, so as to achieve good reception and facilitate the subsequent centralized treatment of dust and impurities; a sliding groove 22 for the dust box 21 to slide is horizontally opened on the outer tube 7. When the dust box 21 is not in use, the dust box 21 can be stored in the sliding groove 22. An elastic reset member 23 is provided on the outer tube 7 to drive the dust box 21 to be stored in the sliding groove 22. The elastic reset member 23 includes a compression spring, one end of which is connected to the dust collector 21. The dust box 21 is fixed, and the other end is fixed to the outer tube 7. The dust box 21 is driven to retract and reset with the help of a compression spring to achieve automatic storage. In addition, a cam 24 is provided at the bottom of the inner core 8 for pushing one end of the dust box 21 out of the slide groove 22. When the inner core 8 is driven to rotate until the laser generator 9 corresponds to the through groove 14, the cam 24 pushes one end of the dust box 21 out of the slide groove 22, so that the dust box 21 is automatically popped out when the laser generator 9 is in use. There is no need to manually operate the dust box 21, which is more convenient and quick. When the inner core 8 is driven to rotate until the laser generator 9 is misaligned with the through groove 14, the dust box 21 is automatically retracted under the action of the elastic reset member 23.
[0030] like Figure 2 and Figure 3As shown, a mounting groove 25 for mounting the wiping portion 17 is provided on the outer tube 7, and the vertical ends of the mounting groove 25 pass through the bottom wall and the top wall of the outer tube 7. The upper and lower ends of the wiping portion 17 pass through the outer tube 7. The wiping portion 17 is vertically slidably connected to the outer tube 7. The wiping area can be switched by pulling the wiping portion 17 up and down, thereby avoiding the situation where the wiping portion 17 wipes the lens in the same area for a long time and makes it dirty, thereby affecting the subsequent wiping effect. The wiping area adjustment operation of the wiping portion 17 is simple and convenient.
[0031] In other embodiments, a top laser generator can be further arranged on the body 1 corresponding to the top of the rotating table 2. The top laser generator is arranged downward, so that the top wall of the stator core 4 can be coded. When the rotating table 2 carries the position where the top wall of the stator core 4 needs to be coded and corresponds to the top laser generator, the top coding is realized, and finally the double coding of the top surface and the side surface of the stator core 4 can be realized, so as to facilitate the subsequent tracing of the production information of the stator core 4.
[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
