[0110] When the connector assembling equipment provided by the application is used, the specific working process is as follows:

[0111] (1) After the first connector positioning mechanism 201 is put into the connector material, the side body 2 is rotated by 60° to rotate the first connector positioning mechanism 201 to the front of the first pin cutting mechanism 3, the first pin cutting mechanism 3 starts to act, the feeding mechanism 3014 pushes the short pin material 3012 to the limiting block 3013, the second cylinder 3017 starts to act downward to make the pre-pressing mechanism 309 press the short pin material 3012, the second cylinder 3017 continues to act downward to make the cutting knife 308 cut into the short pin material 3012, so that the short pin material 3012 changes from a continuous state to an independent state, the second cylinder 3017 starts to act upward to a specified position, at this time, the pre-pressing mechanism 309 still presses the short pin material 3012 which has been cut off and separated, the first cylinder 219 of the connector positioning mechanism 201 acts to push the pushing block 214, the connector positioning block adjusting plate 215, the connector positioning block 216 and the connector 218 until the limiting rod 217 abuts against the second limiting rod 3016, the second cylinder 3017 continues to act upward to the original position, and the first cylinder 219 takes the pushing block 214, the connector positioning block adjusting plate 215, the connector positioning block 216, the connector 218 and the cut-off independent short pin material 3012 back to the original position.

[0112] In the above operation, the short pin material is transmitted by the feeding mechanism 3014, manual transmission is not needed, manual labor is saved, and transmission efficiency can be improved; the feeding mechanism 3014 in the horizontal direction cooperates with the cutting knife 308 in the vertical direction to cut from top to bottom, so that the cutting position can be ensured to be accurate and reliable.

[0115] In the embodiment, the pre-pressing mechanism 309 can pre-press the short pin material, and then cut the short pin material, which can avoid the deviation of the short pin material in the cutting process, and further avoid the inaccurate cutting position and even the waste of the material, thereby improving the yield. Further, the pre-pressing mechanism 309 can include, but is not limited to, a pre-pressing block.
