As shown in figure 1, the utility model discloses a grab line conveying mechanism, including grabbing line subassembly and conveying assembly two parts. The wire grabbing component is arranged on the conveying component and used for clamping or loosening the wire. And the conveying assembly is used for conveying the wires.

Wherein the conveyor assembly, like the conventional apparatus, comprises a conveyor 1 and a robot 3. The conveyor 1 transports the wire in batches along the line, while the robot 3 picks up the wire one by one on the line to be transported to the next station.

The line grabbing component comprises a line body carrier 2, the line body carrier 2 is arranged on a traction piece of the conveyor 1 and works along with the conveyor 1, so that the line body carrier 2 does circular motion.

As shown in fig. 2, a fixed block 21 and a rotatable movable block 22 are arranged on the wire carrier 2, a positioning groove 23 is formed between the fixed block 21 and the movable block 22, and the positioning groove 23 is used for clamping a wire; the movable block 22 is far away from the positioning groove 23 to form an eccentric portion 221, and the eccentric portion 221 is pressed to rotate the movable block 22 to the side far away from the positioning groove 23, so as to enlarge the width of the positioning groove 23 for the wire to pass in and out. Therefore, the eccentric part 221 is stressed, so that the end part of the movable block 22 generates torque relative to the joint of the movable block 22 and the linear body carrier 2, the movable block 22 rotates, and the side wall of the positioning groove 23 is the wall surface of the movable block 22.

Specifically, the fixing block 21 is directly fixed to the wire carrier 2 by screws. And the movable block 22 can be rotated in various ways.

For example, the movable block 22 and the wire carrier 2 are also fixedly connected or integrally formed, and are rotated by elastic deformation of the movable block 22. However, after a long period of use, the elastic deformation of the movable block 22 is accumulated as plastic deformation, and the elastic force of the movable block 22 is insufficient, so that the wire cannot be maintained, and the entire wire needs to be discarded.

Therefore, the movable block 22 is preferably pivotally connected to the wire carrier 2, and the wire carrier 2 is provided with an elastic member, which allows the movable block 22 to hold the wire in the positioning groove 23. The wire body carrier 2 is provided with a through hole, and a rotating shaft 24 penetrating through the movable block 22 is erected in the through hole, so that the movable block 22 rotates and is connected with the wire body carrier 2 in a rotating mode.

The lever plate extends the force arm from the eccentric part 221 to the rotating shaft 24, so that the movable block can rotate conveniently. On the contrary, if the rotation space is not provided, the eccentric portion 221 is only a portion of the top surface of the movable block 22, and the arm of force is small, so that it is inconvenient to rotate.

In order to supplement elasticity, the elastic part further comprises a pressure spring clamped between the lever plate and the line body carrier 2, opposite blind holes are formed in the adjacent surfaces of the lever plate and the line body carrier 2, and the blind holes are sleeved at the two ends of the pressure spring to fix the pressure spring. So that the spring force of the torsion spring is supplemented through the pressure spring, and the movable block 22 clamps the wire in the positioning groove 23. Of course, the compression spring can be used independently to provide the clamping force of the movable block 22 to the wire.

Except that the positioning groove 23 is provided with the movable block 22 at one side and the fixed block 21 at the other side, the two sides of the positioning groove 23 can be provided with the rotatable movable blocks 22, and the movable block 22 at any side can enlarge the positioning groove 23, but the positioning groove is high in cost and small in effect, and is not preferred.

And because the clamping jaw 38 is provided with two groups, two points fix the wire, and the wire is stably clamped by the manipulator 3.

To prevent interference, one end of the ram 4 extends between the two sets of the holding jaws 38 and forms a convex portion 41 bent toward the eccentric portion 221 so as to press the eccentric portion 221.

The working process of the wire grabbing conveying mechanism is as follows: the conveyor 3 transports the wires along the assembly line through the wire carrier 2, the conveyor 3 stops after the wires are transported in place, and the pressing head 4 presses down to enable the movable block 22 to rotate, so that the wires are loosened to be grabbed by the manipulator 3 to move the subsequent processes.

In addition, the pressure head 4 and the line body carrier 2 can be used as a wire grabbing component to be independently combined and specially used for solving the fixing problem of the wire harness. For example, the wire carrier 2 is installed on a workbench, the pressing head 4 is arranged on one side of the workbench in a lifting manner, and when a wire needs to be processed, the wire is positioned through the wire carrier 2. When the process is completed, the pressing head 4 presses the eccentric portion 221, so that the positioning groove 23 releases the wire, thereby facilitating the removal of the wire.
