[0006] A further technical solution is that the second clamping fixture and the first clamping fixture are respectively fixed in the middle position of the second clamping seat and the first clamping seat, the second clamping fixture and the first clamping fixture are installed in the middle position of the second clamping seat and the first clamping seat, and the pressure rod is located at the upper end position of the second clamping fixture or the first clamping fixture. When the magnetic steel sheet is placed into the second clamping fixture and the first clamping fixture, the pressure rod presses the magnetic steel sheet downward and presses it into the rotor core.

[0007] A further technical solution is that the second clamping tool and the first clamping tool are respectively provided with insertion holes along the circumference, and the pressure rod is located at the upper end of the insertion hole. The magnetic steel sheet is placed into the insertion hole and the pressure rod is moved up and down to press the magnetic steel sheet into the rotor core after passing through the second clamping tool and the first clamping tool.

When the CCD detector detects that the pressed rotor core is qualified, it is scanned again by the barcode scanner and the data is stored in the computer terminal for subsequent tracing. This structure is a prior art.

[0011] The beneficial effects of the utility model are:

[0012] 1. Compared with manual work, an automatic press-fitting device for motor core uses a press rod to press-fit 16 magnetic steel sheets in two steps in the first pressing tool and the second pressing tool, which greatly saves labor consumption and significantly improves efficiency;

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] See also Figures 1 to 7As shown, an automatic pressing device for a motor core includes a support frame 2 and a conveyor belt 7, wherein the conveyor belt 7 is connected to the support frame 2, and a first pressing seat 1 and a second pressing seat 3 are fixed from left to right on the support frame 2 and located just above the conveyor belt 7, and a first pressing fixture 13 and a second pressing fixture 12 are fixed to the bottom ends of the first pressing seat 1 and the second pressing seat 3, respectively, and a servo press seat 18 is fixed to the first pressing seat 1 and the second pressing seat 3, and a servo press 11 is fixed to the top of the servo press seat 18, and a movable plate 1 is fixed to the output end of the servo press 11 7, a pressing rod 14 is fixed to the bottom end of the movable plate 17, notches 16 are evenly distributed along the circumference of the second pressing seat 3, an infrared sensor 15 is fixed to the second pressing seat 3 and located at the side end of the notch 16, a positioning tool 6 is relatively fixed to the conveyor belt 7, a CCD detector bracket 5 is fixed to the support frame 2 and located at the right end of the second pressing seat 3, a CCD detector 4 is fixed to the CCD detector bracket 5, and an infrared detector 8 is fixed to the first pressing tool 13, the second pressing tool 12 and the front and rear end sides of the CCD detector bracket 5.

[0026] The second clamping fixture 12 and the first clamping fixture 13 are respectively fixed in the middle of the second clamping seat 3 and the first clamping seat 1, and the second clamping fixture 12 and the first clamping fixture 13 are installed in the middle of the second clamping seat 3 and the first clamping seat 1, and the pressure rod 14 is located at the upper end of the second clamping fixture 12 or the first clamping fixture 13. When the magnetic steel sheet is put into the second clamping fixture 12 and the first clamping fixture 13, the pressure rod 14 presses the magnetic steel sheet downward and presses it into the rotor core 19. The second clamping fixture 12 and the first clamping fixture 13 are respectively provided with insertion holes 10 along the circumference, and the pressure rod 14 is located at the upper end of the insertion hole 10. By putting the magnetic steel sheet into the insertion hole 10 and moving the pressure rod 14 up and down, the magnetic steel sheet is pressed into the rotor core 19 after passing through the second clamping fixture 12 and the first clamping fixture 13. There are eight jacks 10 distributed along the circumference on the second clamping fixture 12 and the first clamping fixture 13, and eight pressure rods 14 are fixed along the circumference on the lower end of the movable plate 17. Through the eight jacks 10 in opposite directions on the second clamping fixture 12 and the first clamping fixture 13, the magnetic steel sheet can be pressed into the sixteen holes on the rotor core 19 in two times. A rotor core stopper 20 is also fixed on the upper end of the positioning fixture 6. The rotor core stopper 20 at the bottom of the positioning fixture 6 is used to relatively fix the rotor core 19. The rotor core 19 can be fixed by placing the rotor core 19 on the rotor core stopper 20. A barcode scanner 9 is also fixed on the side end of the support frame 2, and a computer terminal 21 is also fixed on the side end of the support frame 2 and located on the upper end of the barcode scanner 9. The barcode scanner 9 and the CCD detector 4 are electrically connected to the computer terminal 21, and the image detected by the CCD detector 4 can be displayed in the computer terminal 21. The rotor core 19 and the magnetic steel sheet can be marked with a QR code or other label by a marking machine before the clamping process of the magnetic steel sheet. Other labels such as the number 1 represent production line No. 1. Of course, labels can also be affixed by manual labeling. Before pressing, the label or QR code on the rotor core 19 and the magnetic steel sheet is first scanned by the barcode scanner 9. When the CCD detector 4 detects that the pressed rotor core 19 is qualified, it is scanned again by the barcode scanner 9 and the data is stored in the computer terminal 21 for subsequent tracing. This structure is a prior art.

[0027] In this embodiment, before the magnetic steel sheet is pressed, the rotor core 19 and the magnetic steel sheet are scanned into the computer terminal 21. After the scan is confirmed, the magnetic steel sheet is placed in the slot 16 on the first pressing seat 1 and the second pressing seat 3. At this time, the infrared sensor 15 is used to detect whether the magnetic steel sheet is missing in the slot 16. The rotor core 19 is placed on the rotor core limit seat 20 at the upper end of the positioning tool 6 and is relatively fixed. The positioning tool 6 is transported to the first pressing seat 1 station by the conveyor belt 7 and then stops. Infrared detectors 8 are provided on both sides of the first pressing seat 1, which can accurately locate the position of the positioning tool 6. At this time, the rotor core 19 on the core limit seat 20 is directly below the first pressing tool 13, and then the servo press 11 is started to drive the movable plate 17 to move downward, and the movable plate 17 moves downward to drive the pressure rod 14 downward. Move, and the magnetic steel sheet in the slot 16 is passed through the first clamping tool 13 by the pressure rod 14 and then pressed into the rotor core 19. After the pressing is completed, the positioning tool 6 is transported to the workstation of the second clamping seat 3 through the conveyor belt 7. The second clamping seat 3 workstation is also provided with infrared detectors 8 on the front and back sides, which can accurately locate the position of the positioning tool 6. Like the first clamping seat 1, the magnetic steel sheet in the slot 16 is passed through the second clamping tool 12 by the pressure rod 14 and then pressed into the rotor core 19. After the pressing is completed, the positioning tool 6 is returned to the CCD detector 4 workstation through the conveyor belt 7. The workstation is also provided with infrared detectors 8 on the front and back sides, which can accurately locate the position of the positioning tool 6. Then the CCD detector 4 is used to detect whether the magnetic steel sheet is missed or wrongly installed. Finally, the material is taken and put into the qualified product area.

[0028] Among them, the difference between the first clamping seat 1 and the second clamping seat 3 is that the directions of the sockets 10 on the first clamping tooling 13 and the second clamping tooling 12 connected in the middle are in opposite directions, and other parts are consistent. When the magnetic steel sheet is placed in the slot 16, the height of the magnetic steel sheet is greater than the upper and lower slot distances of the slot 16, which can be detected by the infrared sensor 15, and the magnetic steel sheets are evenly placed one by one in the inside and outside directions of the slot 16. The process of sending them into the sockets 10 on the first clamping tooling 13 and the second clamping tooling 12 can be manually pushed, or a telescopic cylinder can be installed on the outside of the slot 16, and the magnetic steel sheet can be pushed to the socket 10 in the slot 16 through the telescopic end of the telescopic cylinder. Of course, other pushing methods can also be used.

[0029] The above is only a specific implementation of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model.
