Further, the auxiliary lock rope push rod mechanism 23 further includes an auxiliary lock rope push rod connecting rod a233 and an auxiliary lock rope push rod connecting rod B232, the auxiliary lock rope actuating motor 234 is hinged to the tail end of the auxiliary lock rope push rod connecting rod a233 through a motor connecting block, a sliding groove 2331 is formed in the middle of the auxiliary lock rope push rod connecting rod a233, the sliding groove 2331 is connected with an auxiliary lock rope connecting rod sliding pin 2322, the auxiliary lock rope connecting rod sliding pin 2322 is fixed to the tail end of the auxiliary lock rope push rod connecting rod B232, the middle of the auxiliary lock rope push rod connecting rod B232 is hinged to the auxiliary lock rope connecting rod pin 2321, the head end of the auxiliary lock rope push rod connecting rod B232 is hinged to the auxiliary lock rope push rod 231, the auxiliary lock rope push rod 231 is provided with a push rod guiding groove 2311, and the push rod guiding groove 2311 is matched with the guiding pin 2312 to achieve guiding of the auxiliary lock rope push rod 231. With the above structure, the sub-lock cord push rod 231 can be linearly moved along the horizontal plane.
Therefore, the rope is fixed with the mechanical arm through the rope locking chuck mechanism 22, the rope is fixed with the looping head separation piece 12 through the auxiliary rope locking push rod mechanism 23, and the rope cannot be separated from the mechanical arm and the looping head separation piece in the transferring process of the looping head separation piece 12 along with the mechanical arm.
And the auxiliary rope locking push rod mechanism is positioned below or above the rope locking chuck mechanism so as to ensure that the upper position and the lower position of the rope in a natural suspension state are respectively locked.
In conclusion, the design of the mechanical arm integrates the functions of grabbing the separating piece of the looping head and locking the rope, so that the color changing of the rope is more stable and reliable.
Because the looping head separating piece 12 is arc-shaped, if the looping head separating piece grabbing mechanism 21 cannot be aligned with the looping head separating piece 12, it is difficult to reliably grab the looping head separating piece 12. If the looper head separation piece grabbing mechanism 21 can swing in a self-adaptive mode in the process of grabbing the looper head separation piece 12, reliable grabbing of the looper head separation piece 12 is guaranteed. Therefore, a self-adaptive follow-up structure of the looping head separation piece transfer manipulator is further provided, as shown in fig. 14, specifically, a follow-up connection assembly is provided between a manipulator arm (including a manipulator Y-direction movement mechanism 25 and a manipulator Z-direction movement mechanism 24) and a manipulator fixing seat 20, and the manipulator fixing seat swings in a self-adaptive manner relative to the manipulator arm through the follow-up connection assembly.
Because it drives the action of manipulator fixing base 20 to moving member 253 through Y, follow-up coupling assembling sets up between Y and manipulator fixing base 20 to moving member 253. The follow-up connecting component comprises a follow-up connecting piece 254, a fixed rotating shaft 202 and a follow-up elastic body 203. Wherein, follow-up connecting piece 254 one end is fixed, and the other end rotates to be connected in fixed rotating shaft 202, and fixed rotating shaft 202 is fixed in manipulator fixing base or manipulator arm, accomplishes the self-adaptation swing back at the manipulator fixing base, realizes restoring to the throne through follow-up elastomer 203.
In this embodiment, the manipulator fixing base 20 is provided with a U-shaped groove 201, and the fixing shaft 202 is disposed in the U-shaped groove. The follow-up elastic body 203 is arranged in the U-shaped groove 201, and the follow-up connecting piece 254 is provided with a follow-up groove 2541 matched with the follow-up elastic body.
