technical field

The invention relates to an ABS sensor cable tie machine, which belongs to the technical field of sensor manufacturing.

Background technique

Cable tie buckles are widely used on ABS sensor wiring harnesses, but these buckles are relatively wide and thick, and require a relatively large force to fasten and cut them.

The existing tightening methods of cable ties are all manually operated by a cable tie gun to tighten the cable tie and then cut it off. This cable tie gun mainly has the following problems and deficiencies:

1. The cable tie gun should always be held in the hand, which is not convenient for the positioning of the cable tie, and the operation is inconvenient;

2. The tightening and cutting of cable ties are all manual operations, the labor intensity of workers is high, and the production efficiency is low. However, the production of ABS sensor wiring harness is a batch operation, which obviously cannot meet the production requirements;

3. The tightening force of the cable tie gun is controlled by the force arm inside the cable tie gun. When the diameter of the coil wrapped by the cable tie changes, the force arm will change, and the tightening force will also change, resulting in unstable tightening force;

4. Because the cable tie gun is manual, for wider and thicker cable ties, the cable tie gun cannot be tightened and cut, so it cannot be used.
