The top surface of the electronic components, so that the lower clamping plate 822 and the upper clamping plate 824 approach from both sides of the cell and clamp the electronic components with the electric core at the end, so as to press the electronic components on the lower clamping plate 822;

4) Adjust the lift drive source 831 to drive the bending assembly to move in the vertical direction through the lift table 832 to adjust the relative position between the bending assembly and the suspended end of the electronic component, and then the second rotational drive source 833 can drive the bending part 834 starts to rotate from below the electronic component, so that the bending piece 834 abuts on the bottom of the electronic component and pushes the electronic component to be turned over to the middle, so as to bend the suspended end of the electronic component;

5) The lower clamping plate 822 and the upper clamping plate 824 release the electronic components, the bending member 834 is reset, and the mobile driving source 842 drives the mobile platform 843 to move in the horizontal direction, so as to realize the first clamping mechanism 81, the second clamping mechanism 82 and the The whole of the bending mechanism 83 moves in a direction away from the rotary table 11 and is reset.
