The direction of the incoming skeleton A is confirmed by the direction detection device 25, and for the skeleton A that does not meet the direction, the docking vehicle 22 adjusts the direction in time to ensure that the PIN needle B of the subsequent solder is in the correct position. At the same time, the direction detection device 25 can also center and position the skeleton A to ensure that skeletons A of different sizes can be located at the center of the docking vehicle 22, so that they can be accurately mounted on the positioning fixture 10 later.

[0042] The docking vehicle 22 includes a rabbit cage 221 for inserting and positioning the skeleton A, at least one floating clamp 222 arranged on one side of the rabbit cage 221 and used to elastically clamp the skeleton A, and a rotating device 223 installed on the cutting module 21 and used to drive the rabbit cage 221 to rotate, wherein the rabbit cage 221 has a positioning cavity consistent with the shape of the skeleton A, and a part of the floating clamp 222 extends into the cavity, and a wedge surface is arranged at one end to facilitate the insertion of the skeleton A.

When the skeleton A is mounted on the fourth positioning block 253 in the correct direction, since the avoidance slot A1 can be directly opposite to the floating rod 2541, the induction sensor 2542 will not react. The system determines that the direction of the skeleton A is correct, and the rotating device 223 does not need to drive the rabbit cage 221 to rotate 180°; when the skeleton A is mounted on the fourth positioning block 253 in the opposite direction, the end face of the skeleton A will be pressed and contacted with the floating rod 2541, and the floating rod 2541 will be pushed back to trigger the induction sensor 2542 to react.
