Description

Technical Field

[0001] The present invention relates to the field of stator core production equipment, in particular to a stator core side marking device. Background Art

[0002] The stator core is a key component of electric motors (such as generators and motors). It is the core of the motor's stator, providing a low-reluctance path for the motor's magnetic field. During operation, the stator core effectively concentrates and guides the magnetic field, enabling the motor to efficiently convert electrical and mechanical energy.

[0003] With the continuous development of current technology, the production information of stator cores is gradually tending towards electronic information. In order to better trace the initial production batch of stator cores and related information, stator cores are usually labeled during the production process. The labeling can be used to obtain the corresponding stator core production-related information. However, the labeling method is poorly integrated with the stator core and has poor stability. That is, there is a risk of falling and losing the label in the later stage, which needs further improvement. Summary of the Invention

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] A stator core side marking device, such as Figure 1 As shown, it includes a body 1, a rotating table 2 is provided on the body 1, and a positioning member for positioning the stator core 4 is provided 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, and 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, and the stator core 4 is placed on the rotating table 2 for positioning. The conical top of the positioning column 3 is convenient for the placement operation of the stator core 4, and a driving member for driving the stator core 4 to rotate is provided 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.

[0027] 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. The laser generator 9 can be used to mark a QR code on the side of the stator core 4. The QR code 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.

[0028] 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 through the two-dimensional code.

[0029] 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 provided 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. A tightening bolt 12 and a tightening nut 13 are provided at the end of the mounting portion 10 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.

[0030] like Figure 1 and Figure 2 As shown, the mounting box 6 includes an outer cylinder 7 and an inner core 8. The inner core 8 is rotatably connected to 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 provided 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 be used to mark the side wall of the stator core 4. When not in use, the inner core 8 can be rotated so that the lens of the laser generator 9 is misaligned with the through groove 14, thereby realizing the storage of the laser generator 9 and providing good storage protection for the lens of the laser generator 9.

[0031] 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 to the output end of the driving motor 15, and the inner core 8 is driven to rotate by the driving motor 15 to realize the position adjustment of the laser generator 9; in addition, a blowing component 16 is embedded in the side wall of the inner core 8, and the blowing component 16 can specifically be a hair dryer. In this way, 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, thereby ultimately ensuring that the quality of marking is more guaranteed and saving the cleaning link in the process.

[0032] 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 facing 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 cleaning and wiping of the lens on the laser generator 9 can be achieved 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.

[0033] like Figure 2 and Figure 3 As shown, a plurality of air blowing nozzles 18 are provided on the top wall of the through groove 14, and the air blowing nozzles 18 are arranged toward the inner core 8. An air cavity 19 is opened on the inner wall of the outer tube 7. When the laser generator 9 and the through groove 14 are in corresponding positions, the blowing assembly 16 corresponds to the air cavity 19, and the air blowing nozzle 18 is connected to the air cavity 19, and the air cavity 19 is used to provide an air source to the air blowing nozzle 18; in this way, when the lens of the laser generator 9 corresponds to the through groove 14, the air blowing nozzle 18 can blow air to clean the lens surface, thereby realizing the cleaning of the lens surface when the laser generator 9 is in use, and adding another way to clean the lens on the laser generator 9.

[0034] 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 cylinder 7 corresponding to the guide surface 20. The dust box 21 is horizontally slidably connected to the outer cylinder 7. The dust box 21 is used to receive the dust and impurities blown off, thereby achieving good reception and facilitating the subsequent centralized treatment of the dust and impurities. A sliding groove 22 for the dust box 21 to slide is horizontally provided on the outer cylinder 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 cylinder 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 the compression spring is in contact with the dust collecting box 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.

[0035] 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, avoiding the situation where the wiping portion 17 wipes the lens in the same area for a long time and makes it dirty, which affects the subsequent wiping effect. The adjustment operation of the wiping area of ​​the wiping portion 17 is simple and convenient.

[0036] In other embodiments, a top laser generator can be further provided on the machine 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 position on the rotating table 2 with the top wall of the stator core 4 requiring coding corresponds to the top laser generator, the top coding is achieved, and finally double coding of the top and side surfaces of the stator core 4 can be achieved, so as to facilitate the subsequent tracing of the production information of the stator core 4.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
