In another embodiment of the present application, as shown in fig. 5, the material taking device 60 of the transformer plug-in machine 100 further includes a first connecting frame 65, two connecting components 66 and two first connecting plates 67, the piston rod of the first lifting cylinder 62 is connected with the first connecting frame 65, the first transformer clamping hand 63 and the second transformer clamping hand 64 are respectively installed on the two first connecting plates 67, the two first connecting plates 67 are respectively connected with the first connecting frame 65 through the two connecting components 66, the two connecting components 66 each include a first fastening member 661 and a first elastic member 662, the first connecting frame 65 and the first connecting plates 67 are in sliding connection through the first fastening member 661 and can enable the first connecting plates 67 to slide up and down relative to the first connecting frame 65, the first elastic members 662 are sleeved outside the first fastening member 661, two ends of the first elastic members 662 are respectively abutted to the first connecting frame 65 and the first connecting plates 67, the connecting components 66 further include a first detecting member 663 for detecting the distance between the first connecting plates 67 and the first connecting frame 65, the first lifting cylinder module 62 and the first elastic member 663.

Specifically, the first lifting cylinder 62 drives the first transformer holder 63 to move down, and in the process of inserting the pins of the transformer 91 into the shaping device 40 for shaping, if the pins of the transformer 91 are deformed greatly, the pins of the transformer 91 cannot be inserted into the shaping device 40, at this time, as the first lifting cylinder 62 continues to move down, the first connecting plate 67 connected with the first transformer holder 63 is pushed to move up relative to the first connecting frame 65, at this time, the distance between the first connecting plate 67 and the second connecting frame 73 changes, when the distance value is greater than a preset value, the first detecting member 663 is triggered, and the first detecting member 663 feeds back signals to the linear module 61, the first lifting cylinder 62 and the first transformer holder 63, so that the linear module 61 and the first lifting cylinder 62 are controlled to drive the first transformer holder 63 to move, so that the pins are moved out of the shaping device 40 for discharging, the transformer 91 with the larger pins can be identified, and the discharging device 60 is utilized for discharging unqualified transformers 91, and thus the subsequent transformer 91 can be directly discharged for high-speed and high-efficient shaping operation. Similarly, the first lifting cylinder 62 drives the second transformer holder 64 to move downwards, and in the process of placing the pins of the transformer 91 in the positioning device 50, if the pins of the shaped transformer 91 do not conform to the preset shape, the pins of the transformer 91 cannot be inserted into the positioning device 50, at this time, as the first lifting cylinder 62 continues to move downwards, the first connecting plate 67 connected with the second transformer holder 64 is pushed to move upwards relative to the first connecting frame 65, at this time, the distance between the first connecting plate 67 and the second connecting frame 73 changes, when the distance value is greater than the preset value, the first detecting member 663 is triggered, and the first detecting member 663 feeds back signals to the linear module 61, the first lifting cylinder 62 and the second transformer holder 64, so that the linear module 61 and the first lifting cylinder 62 are controlled to drive the second transformer holder 64 to move, so that the pins are deformed greatly to move out of the positioning device 50 and perform discharging treatment, and thus the shaped unqualified transformer 91 can be directly discharged, and the following transformer 91 is ensured to be inserted and operated efficiently and quickly. In addition, since the first elastic member 662 is disposed between the first connecting plate 67 and the first connecting frame 65, in the process of inserting the pins of the transformer 91 into the shaping device 40, the first elastic member 662 will provide an upward moving resistance to the first connecting plate 67, which overcomes the resistance of inserting the pins of the transformer 91 into the shaping device 40 or the resistance of inserting the transformer 91 with smaller deformation of the pins into the shaping device 40, so as to ensure that the pins are not deformed or the insertion of the transformer 91 with smaller deformation into the shaping device 40 will not drive the first connecting plate 67 to move upwards, thereby preventing the material taking device 60 from discharging by mistake.
