[0041] See also Figure 1-Figure 9 , a TO-CAN pin automatic bending and shearing device 2 is used for bending and shearing the pins of a TO-CAN packaging structure 100.

[0042] The TO-CAN package structure 100 includes a housing 120 and a plurality of pins 140 . The housing 120 includes an end cap 122 and a base 124 covering each other. A portion of the plurality of pins 140 is located in the end cap 122 , and another portion passes through the base 124 and extends out of the end cap 122 .

[0045] The loading and unloading structure 80 is used to place the TO-CAN packaging structure 100 to be bent or sheared.

[0046] The first robot 40 is used to move the TO-CAN packaging structure from the loading and unloading structure 80 to the bending and shearing platform 20 by clamping the end cap 122, so that the multiple pins 140 are inserted into the multiple through holes 221; and after the multiple pins 140 are bent and sheared, the TO-CAN packaging structure is returned to the loading and unloading structure 80.

[0047] The second manipulator 60 is used to clamp the base 124 when the plurality of pins 140 are inserted into the plurality of through holes 221 and extend into the slot 241;

[0048] Among them, when multiple pins 140 are inserted into multiple through holes 221, the first manipulator 40 clamps the end cap 122 and the second manipulator 60 clamps the base 124 to keep the spatial position of the shell 120 unchanged, the first body 22 and the second body 24 move relative to each other, thereby achieving different degrees of bending of the multiple pins 140 and cutting of the pins.

[0049] See also Figure 2-Figure 9 A bending and shearing platform 20 is used to bend and shear a plurality of pins 140 of a TO-CAN packaging structure 100.

[0050] The TO-CAN package structure 100 includes a housing 120 and a plurality of pins 140 , wherein a portion of the plurality of pins 140 is located inside the housing 120 and another portion extends outside the housing 120 .

[0051] The bending and shearing platform 20 includes: a first body 22 , a second body 24 and a driving assembly 23 .

[0052] The first body 22 is provided with a plurality of through holes 221 ; the plurality of through holes 221 correspond one-to-one to the plurality of pins 140 , and the TO-CAN packaging structure 100 can be placed in the first body 22 in a manner that the plurality of pins 140 are inserted into the plurality of through holes 221 ; the apertures of the plurality of through holes 221 are not completely the same.
