[0019] Refer to Figures 1 to 3 A kind of material discharging and grasping structure for transformer connecting pieces shown in the figure, which includes a large bottom plate, a grasping mechanism and a material discharging and sorting mechanism. The grasping mechanism and the material discharging and sorting mechanism are both installed on the large bottom plate 22. The material discharging and sorting mechanism is arranged on one side of the grasping mechanism. The material discharging and sorting mechanism includes a scrap collection box 3 and a material discharge channel 4. The grasping mechanism includes a cross beam 7, a cylinder 2 8, a guide rail, a slider, a cylinder 3 (not shown), a cylinder 4 15 and a claw 16. The claw 16 can move in the vertical and horizontal directions.

[0020] Furthermore, a support column 6 is installed on the large bottom plate 22, the cross beam 7 is installed on the support column 6, the cylinder 2 8 is installed at one end of the cross beam 7. The guide rail includes a guide rail 1 9 and a guide rail 2 12. The slider includes a slider 1 10 and a slider 2 13. The guide rail 1 9 is installed on one side of the cross beam 7. The slider 1 10 is connected with the guide rail 1 9. The telescopic end of the cylinder 2 8 is connected with the slider 1 10. An installation plate 11 and a guide rail 2 12 are installed on the slider 1 10. The slider 2 13 is connected with the guide rail 2 12. The cylinder 3 is installed on the installation plate 11. The telescopic end of the cylinder 3 is connected with the slider 2. One end of the slider 2 13 is installed with a vertical plate 14, and the cylinder 4 is installed on the vertical plate 14.

[0021] Furthermore, a connecting block 17 is installed on one side of the cylinder 4 15. An installation seat 18 is installed on the connecting block 17. A pressing rod 19 is fixed on the installation seat 18. The installation seat 18 and the pressing rod 19 are arranged inside the claw 16. One end of the pressing rod 19 extends into the interior of the installation seat 18. A spring (not shown) is arranged between the pressing rod and the installation seat.

[0022] Furthermore, a column 1 is installed on the large bottom plate 22, a cylinder 1 2 is installed on the column 1. The scrap collection box 3 is fixedly connected with the telescopic end of the cylinder 1 2. The material discharge channel 4 is installed on one side of the scrap collection box 3.

[0023] Further, a turntable 21 is provided at the upper end of the large bottom plate. A plurality of connecting piece storage seats 20 are provided on the turntable 21, and the connecting pieces 23 are placed on the connecting piece storage seats.

[0024] Further, the turntable can complete the rotation operation under the action of a motor.

[0025] When the present utility model is in use, after the riveting of the connecting pieces is completed, the connecting pieces move to the blanking and grasping structure together with the connecting piece storage seats and the turntable. When the sensor detects that the connecting pieces are in place (and at the same time confirms whether the connecting pieces are qualified products or defective products in the previous process), the second cylinder and the third cylinder work, driving the jaws to move vertically and horizontally. The jaws move to directly above the connecting pieces (at this time, the jaws are in an open state). When the first pressure bar contacts the connecting pieces first, the pressure bar fixes the connecting pieces on the connecting piece storage seats. Subsequently, the fourth cylinder drives the jaws to clamp the connecting pieces. Under the action of the second cylinder and the third cylinder, the connecting pieces are moved to the blanking channel. When the detected connecting pieces are qualified products, the jaws open, and the connecting pieces fall into the blanking channel. When the detected connecting pieces are defective products, the first cylinder pushes the waste collection box to move, and the waste collection box replaces the original position of the blanking channel. Then the jaws place the defective connecting pieces in the waste collection box. Subsequently, the grasping mechanism resets, and the blanking mechanism selects whether to reset according to the detection situation of the next connecting piece; finally, the automatic grasping and blanking operation of the connecting pieces is achieved.

[0026] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
