[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0023] like Figures 1 to 8 In the embodiment of the annular steel sheet feeding mechanism for magnet assembly shown in this utility model, the mechanism has a base plate 10 with a support seat 20, a lower support plate 21 on the support seat 20, and a column 22 on the lower support plate 21. The annular steel sheet 101 to be assembled is fitted onto the column 22. A vertically arranged linear motor 30 is also installed on the base plate 10. A fork plate 32 located below the annular steel sheet 101 is installed on the lifting slide 31 of the linear motor 30. When the linear motor 30 drives the fork plate 32 to move upward, the fork plate 32 lifts the annular steel sheet 101 stacked on the column 22 upward. Yes, the annular steel plates 101 stacked on the column 22 are closely attached to each other. The vertical gap between the adjacent annular steel plates 101 in the attached drawings is only for illustration. The annular steel plates 101 are provided with notches. The outer contour of the column 22 is cylindrical and the side wall is provided with guide vertical plates 221 corresponding to the notches on the annular steel plates 101. The guide vertical plates 221 are inserted into the notches of each annular steel plate 101, thereby positioning the annular steel plates 101 so that the notches of each annular steel plate 101 are in the same direction. As the annular steel plates rise along the column, the guide vertical plates can also guide the annular steel plates.

[0024] The ring steel sheet feeding mechanism for magnet assembly in this application has ring steel sheets stacked on columns and reliably moving upwards under the lifting action of fork plates, ensuring that the uppermost ring steel sheet is in a preset position; the guide vertical plate can position and guide each ring steel sheet, so that the ring steel sheets do not flip over and remain stable in the above process, avoiding unreliable adsorption and accidental detachment caused by the non-level surface of the ring steel sheet, thus ensuring high reliability.

[0025] In one embodiment of this application, preferably, as shown below,Figures 5 to 8 As shown, a vertical groove is formed on the side wall of the column 22, and a vertical connecting block 222 is installed in the groove. A guide plate 221 is set on the vertical connecting block 222, thereby facilitating manufacturing and assembly. Preferably, two or more vertical connecting blocks 222 are installed in the groove from bottom to top, with the bottom of the bottom vertical connecting block 222 flush with the bottom of the column 22, and the top of the top vertical connecting block 222 flush with the top of the column 22. Figure 8 As shown, three vertical connecting blocks 222 are installed from bottom to top in the vertical groove of the column 22, which facilitates manufacturing and assembly.

[0026] In one embodiment of this application, preferably, the lower support plate 21 includes a connecting part 211 and a support part 212, the column 22 is mounted on the support part 212, and the inner contour of the fork on the fork plate 32 is adapted to the outer contour of the support part 212; the thickness of the fork plate 32 is less than or equal to the thickness of the lower support plate 21, and in the initial state, the upper surface of the fork plate 32 is flush with the upper surface of the lower support plate 21, making the structure of the ring steel sheet feeding mechanism for magnet assembly compact.

[0027] In one embodiment of this application, preferably, the base plate 10 is further provided with a vertical plate 40 near the support base 20. A translation cylinder 41 is installed on the top of the vertical plate 40. A lifting cylinder 42 is installed at the end of the horizontal telescopic rod of the translation cylinder 41. A fixing plate 43 is installed on the telescopic rod of the lifting cylinder 42. Three or four suction nozzles 44 corresponding to the upper surface of the annular steel sheet 101 are installed on the fixing plate 43. The upper end of the suction nozzle 44 is also connected to a vent pipe that moves with the suction nozzle 4. The suction nozzle 44 uses the principle of negative pressure adsorption to adsorb the magnetic block.

[0028] In one embodiment of this application, preferably, a position detection sensor 45 is also installed on the upright plate 40 to detect whether the annular steel sheet 101 at the top of the column 22 is located in a preset position, thereby ensuring that the suction nozzle 44 can accurately and reliably adsorb and transfer the annular steel sheet.

[0029] like Figure 1 The diagram shown is a schematic of the use of the annular steel sheet feeding mechanism for magnet assembly of this application. The feeding structure can sequentially transfer the annular steel sheet 101 to the annular loading platform 210 on the workbench 200. Specifically, the workbench 200 is provided with a rotatable annular disk 220, and multiple annular loading platforms 210 are evenly arranged on the annular disk 220. When the annular loading platform 210 rotates with the annular disk 220 to the feeding position close to the feeding mechanism, the feeding mechanism can sequentially transfer the annular steel sheet 101 to the annular loading platform 210.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
