Background technique

Cables are an important part of the product and an important production material. Commercially available cables are generally of fixed length. In actual production, the cables should be cut into different lengths according to the needs, and then wound up according to a certain size specification. Among them, the cable specification, the required length specification, and the quantity of each batch vary greatly. At present, there is no special equipment to meet this specific demand, and the process of cutting and winding (referred to as offline) by hand is:

First put the bundled cables on the bracket, then pull the cable head and unfold the cables in the corridor, determine the length of the cables according to the landmarks, then cut the cables with pliers, and then roll up the cut cables.

Manual winding has the following disadvantages:

1) Low efficiency It takes 18-30 minutes to go offline for 100 meters, which seriously affects the delivery time.

2) Low accuracy The accuracy of the landmark used as a length reference is low, and the cable deployed on the ground is difficult to straighten, which affects the accuracy of length measurement.

3) The labor intensity is high. The cables are unrolled in the corridor, and then rolled up. The workers walk back and forth. Based on the daily maximum off-line of 45 kilometers, the cumulative walking distance of the workers is 90 kilometers, and they are very tired.

4) The investment is large and the cost is high. According to the production demand, many workers need to work overtime frequently to meet the demand. The investment is relatively high, and a 100-meter-long corridor is required to wind the cable.

5) The cable is easily damaged, and the surface of the cable is easily contaminated with dust and worn.
