The left-right detection drive mechanism drives the carrier to move to the middle of the two transport modules, that is, the center detection position. After the connecting piece is placed on the carrier, the first front-back detection drive mechanism drives the carrier to be conveyed in the downstream direction, and the first camera or the second camera performs detection. Finally, after the connecting piece on the carrier is taken away, the left-right detection drive mechanism returns to its position first, and then the first front-back detection drive mechanism returns to its position, so that the connecting pieces of the two transport modules can be transported separately at the center detection position, and the connecting pieces do not affect each other when being transported, thereby improving the detection efficiency;

[0008] The third inspection station includes a carrier, a third front-to-back inspection driving mechanism for driving the carrier to move forward and backward, and a second camera located above the carrier;

[0009] The sorting station comprises a plurality of sorting nozzle assemblies, a rotating sorting drive mechanism for driving the sorting nozzle assemblies to rotate, a lifting sorting drive mechanism for driving the sorting nozzle assemblies to move up and down, and a left and right sorting drive mechanism for driving the nozzle assemblies to move left and right.

Through the structural setting of this carrier, the connecting part can be positioned by the carrier regardless of whether the connecting part is placed upright or turned over and placed upside down.

[0015] Furthermore, the loading station includes a carrier and a front and rear loading drive mechanism for driving the carrier to move forward and backward.

[0016] Furthermore, the first transplanting module includes a transplanting nozzle assembly, a first lifting and transplanting driving mechanism for driving the transplanting nozzle assembly to move up and down, and a first front-to-back transplanting driving mechanism for driving the transplanting nozzle assembly to move back and forth.

The left-right inspection driving mechanism drives the carrier to move to the middle of the two transport modules, i.e., the center inspection position. After the connecting piece is placed on the carrier, the first front-back inspection driving mechanism drives the carrier to transport in the downstream direction, and performs inspection and detection through the first camera or the second camera. Finally, after the connecting piece on the carrier is taken away, the left-right inspection driving mechanism returns to its position first, and then the first front-back inspection driving mechanism returns to its position, so that the connecting pieces of the two transport modules can be transported separately at the center inspection position, and the connecting pieces do not affect each other when being transported, thereby improving the inspection efficiency.
