[0038] The clamping assembly 7 is adapted to clamp the unbent portion of the lead pin 5 when the bending section 6 is returned to its original position. Figure 2 , 4As shown in FIG. 6 , it comprises: a stopper 31 fixedly arranged on the jig 3 and capable of abutting against one side of the unbent portion of the lead pin 5; a clamp 16, which moves up and down following the jig 3 and can move horizontally relative to the jig 3, the clamp 16 having a slider 17 slidably mounted on the jig 3 and a clamp 18 arranged opposite to the stopper 31, the clamp 16 having a first position separated from the unbent portion of the lead pin 5, and a first position moving toward the stopper 31 and away from the unbent portion of the lead pin 5. In the second position where the two clamps are in contact with each other, a first elastic member 23 is provided between the slider 17 of the clamp 16 and the baffle 20, and the first elastic member 23 is suitable for applying an elastic force to the clamp 16 to move in the direction of the first position; a reversing drive member 19 is vertically arranged in the vertical channel of the workbench 1 and extends into the middle longitudinal channel 30 of the fixture 3.

[0040] The working principle of the relay coil lead pin return device of the utility model is as follows:

[0041] First, the coil skeleton 2 is placed on the fixture 3, and the driving block 27 drives the fixture 3 to move downward. At this time, the deformation of the third elastic member 25 is very small, that is, the longitudinal position of the reversing driving member 19 hardly changes. The second inclined surface 22 of the clamping member 16 slides in contact with the reversing driving member 19, driving the clamping member 16 to move laterally, and the clamping block 18 of the clamping member 16 moves toward the direction close to the stopper 31, thereby cooperating with the stopper 31 to clamp the lead pin 5. In this process, the linkage shaft 11 follows the fixture 3 to move along the first slide groove 13;

[0042] Then the jig 3 continues to move downward, the clamp 16 and the reversing drive member 19 move downward as a whole, the third elastic member 25 is squeezed to accumulate energy, the linkage shaft 11 and the second slide groove 14 slide together, thereby driving the return member 8 to rotate around the rotating shaft 9, and the return block 10 rotates toward the direction close to the coil frame 2. When the coil frame 2 moves downward, its bending section 6 is driven by the return block 10. When the linkage shaft 11 moves to the third slide groove 15, the return of the bending section 6 is completed (such as Figure 7 shown).

[0043] The relay coil lead pin return device provided by the utility model comprises a workbench 1, a return component 4 and a clamping component 7. The return component 4 is suitable for returning the bent section 6 of the lead pin 5, and the clamping component 7 is suitable for clamping the unbent part of the lead pin 5 when the bent section 6 is returned. Compared with the prior art, this improves production efficiency, prevents the lead pin from changing in length or becoming loose and deformed during the return process, thereby ensuring product quality.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
