[0039] As shown in Figure 1 and Figure 7As shown, the sending clamp mechanism 300 includes a truss manipulator, which can realize three-axis movement, including a clamping manipulator and a grafting clamp carrying device. The grafting clamp carrying device includes a front pushing cylinder 321 arranged on a front pushing cylinder fixed plate 322, used to realize horizontal forward and backward movement of the clamping manipulator holding the grafting clamp, the front pushing cylinder fixed plate 322 is connected with a vertical cylinder piston rod 333, and a vertical cylinder 331 is arranged on a vertical guide rail fixed plate 332, used to realize vertical upward and downward movement of the clamping manipulator holding the grafting clamp; the vertical guide rail fixed plate 332 is fixed on a horizontal cylinder guide rail 342, the horizontal cylinder guide rail 342 is fixed on a grafting clamp carrying device rack 351, and is connected with a horizontal cylinder 341, used to realize horizontal left and right movement of the clamping manipulator holding the grafting clamp, through cooperation of each actuator, upward, downward, forward and backward, and left and right movement of the grafting clamp is realized, and the grafting clamp is sent to the grafting station.

[0042] The working process is as follows:

[0043] The uncut grafting clip A is manually put into the clip feeding channel 111. Since the designated cutting position is the upper end surface of the grafting clip A which is flush with the upper end surface of the clip feeding channel 111, before the equipment is started, the grafting clip A has two position states, one is that the top end of the grafting clip A exceeds the upper end surface of the clip feeding channel 111, and the other is that the top end of the grafting clip A does not reach the upper end surface of the clip feeding channel 111. Therefore, before the equipment is formally worked, the grafting clip A needs to be brought to the designated cutting position. In this design, the optical fiber sensor is used as the condition for judging the position of the grafting clip. Before the equipment is started, if the top end of the grafting clip A exceeds the upper end surface of the clip feeding channel 111, the optical fiber sensor has a signal, and the first driving device 123 needs to be reversed to drive the grafting clip to move downward until the optical fiber sensor has no signal, and the motor is reversed to stop. If the top end of the grafting clip A does not reach the upper end surface of the clip feeding channel 111, the optical fiber sensor has no signal, and the motor needs to be forward to drive the grafting clip to move upward until the optical fiber sensor has a signal, and the motor is forward to stop. After the motor stops in the two position conditions, the grafting clip is a distance away from the designated position, and a distance needs to be adjusted to ensure that the top end of the grafting clip A is flush with the upper end surface of the clip feeding channel 111.

[0044] After the grafting clip A reaches the designated cutting position, the horizontal cylinder 341 is extended, the clamping manipulator moves horizontally to the left, after the action is completed, the vertical cylinder 331 is extended, the clamping manipulator moves vertically downward, so that the left clamping finger 311 and the right clamping finger 312 reach the ready-to-take-clip position, then the cutting cylinder is extended to drive the tool holder 220 to move, and after a delay for a period of time, the cutting cylinder is retracted, and the grafting clip is cut for a fixed distance.

[0045] After the cutting action is completed, the first driving device 123 is forward for a fixed distance, so that the grafting clip reaches the take-clip position, after reaching the position, the front pushing cylinder 321 is extended to drive the left clamping finger 311 and the right clamping finger 312 to reach the take-clip position, after reaching the position, the finger cylinder 313 is extended to drive the clamping manipulator to perform clamping action, and the taking of the clip is completed, then the front pushing cylinder 321 is retracted, so that the clamping manipulator returns to the ready-to-take-clip position, after the action is completed, the vertical cylinder 331 is retracted, the clamping manipulator moves vertically upward, the horizontal cylinder 341 is retracted, the clamping manipulator moves horizontally to the right, the vertical cylinder 331 is extended, the clamping manipulator moves to the ready-to-clip position under the drive of the cylinder, and it is judged whether the grafting and scion butt joint is completed. If the butt joint is not completed, waiting is performed, and if the butt joint is completed, the front pushing cylinder 321 is extended to drive the left clamping finger 311 and the right clamping finger 312 to reach the clip position, the finger cylinder 313 is retracted to drive the clamping manipulator to release the grafting clip, the clipping is completed, then the front pushing cylinder 321 is retracted, and the vertical cylinder 331 is retracted, so that the clamping manipulator returns to the original position, and is ready for the next taking action.
