Transplanting module 03 is used to drive the Z-axis gripping module 02 to move; Press-fit module 04 is used to press the iron core 23 gripped by Z-axis gripping module 02 into the housing.

[0025] In a preferred embodiment of the invention, the Z-axis gripping module 02 grips the iron core 23 from the external TARY disk.

[0026] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the jig floating transfer module 01 includes a floating carrier 11 and a hydraulic buffer 18.

The head of the PBR cylinder 117 is connected to the floating joint 16.

[0027] In a preferred embodiment of the invention, a support leg 19 is fixedly connected to the bottom of the base plate 12 for support; the slide cylinder 116 is fixed to the base plate 12 via mounting seat 13, the PBR cylinder 117 is fixed to the base plate 12 via mounting seat 2 15, and the hydraulic buffer 18 is fixed to the base plate 12 via mounting seat 3 17. The front gripper picks up the product and places it on the floating carrier 11. The PBR cylinder 117 pushes the floating carrier 11 into the pressing module 04. The finger cylinder 113 drives the straightening gripper 111 and the straightening gripper 2 112 to straighten the positioning tongue 127, waiting for the pressing module 04 to press it.

[0028] like Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the floating carrier 11 includes a floating plate 120 and a platform base plate 121.

A spring 213 is provided between the four ejector pins 27.

[0031] In this embodiment of the invention, preferably, a limiting block 3 211 and a limiting block 4 212 are fixedly connected to the bottom plate 25 to limit the top plate 29. The specific operation of gripping the iron core 23 is as follows: the guide positioning tongue 1 is inserted into the iron core 23, and the iron core 23 is held in place by the elasticity of the spring 10.

[0032] like Figure 6 As shown, in a preferred embodiment of the present invention, the transplanting module 03 includes a mounting plate 33, a drag chain groove 34 is provided in the mounting plate 33, a drag chain 35 is movably provided in the drag chain groove 34, and the end of the drag chain 35 is connected to the mounting plate 31 through the mounting plate 2 32. The Z-axis gripping module 02 is mounted on the mounting plate 31.

[0033] In a preferred embodiment of the invention, by setting components such as drag chain groove 34, drag chain 35 and mounting plate 31, the transfer module 03 is driven so that the transfer module 03 moves the Z-axis gripping module 02 above the pressing station.

[0034] like Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, a smooth rod support 312 is fixedly connected to one side of the mounting plate 33, a support rod 311 is fixedly connected inside the smooth rod support 312, a smooth rod support foot 313 is fixedly connected to the bottom of the support rod 311, and a foot support plate 37 is fixedly connected to the bottom of the mounting plate 33. The foot support plate 37 is fixed on the foot mounting plate 38, and a reinforcing rib 39 is fixedly connected between the foot mounting plate 38 and the foot support plate 37.

[0035] In a preferred embodiment of the invention, the base mounting plate 38 is provided with an adjustable top block.

[0036] like Figure 8 As shown, in a preferred embodiment of the present invention, the press-fit module 04 includes a servo electric cylinder 41, which is fixed to the support leg 43 by a mounting plate 44. A linear bearing 47 is provided on the mounting plate 44. The end of the servo electric cylinder 41 is connected to the electric cylinder connector 42. A fixing plate 49 is fixedly connected to the electric cylinder connector 42. The fixing plate 49 is connected to the support leg 43 by an anti-rotation auxiliary rod 48. A mounting plate 410 is fixedly connected to the fixing plate 49. A pressure sensor 46 is fixedly connected to the mounting plate 410.

[0037] In a preferred embodiment of the invention, the servo electric cylinder 41 presses the iron core 23 into place, and during the pressing process, the pressure sensor 46 provides real-time feedback of the pressure curve to determine whether the pressing is qualified and to prevent overpressure, insufficient pressing, and other situations from occurring.

[0038] The working principle of this invention is: This fully automatic iron core pressing mechanism uses a TARY feeding mechanism to move the iron core 23 to a designated position. The Z-axis gripping module 02 grips the iron core 23, and the transfer module 03 moves the Z-axis gripping module 02 above the pressing station. The Z-axis gripping module 02 then descends to the pre-pressing position (the guide positioning tongue 21 and the positioning tongue plate 127 are staggered to ensure smoother pressing of the iron core 23). Subsequently, the servo cylinder 41 of the pressing station moves downwards, pressing against the top plate 29. The top plate 29 drives the ejector pin 27 downwards, which presses the iron core 23 evenly into the product casing. After pressing, the mechanism resets to await the next process.

[0039] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
