Sheathed line swelling detecting device and method

Abstract

The invention discloses a sheathed line swelling detecting device which comprises a die base. A half die is placed in the die base. A magnet is placed below the die and attracts the die. The inner diameter of the die is slightly larger than the outer diameter of an optical cable sheath. Guide rods are designed on the two sides of the die base to stabilize an optical cable and prevent the optical cable from shaking. In normal production, the optical cable can smoothly pass through the half die, once the surface of the sheath swells, friction force can drive the half die out of the die base, at the moment, a proximity switch is switched on and an alarm is given, an operator is likely to process the swelling defect in time, record the quality and conduct rectifying and reforming by counting and analyzing the defect conditions, less rejected products are produced and unexpectedly flow to customers, the device is simple, practical, efficient and economical, and expected aims can be achieved.

Description

technical field [0001] The invention relates to the technical field of on-line optical cable production, in particular to a sheath wire bulge detection device and a detection method thereof. Background technique [0002] With the improvement of the market demand for optical cable products, more and more enterprises have increased the production speed of optical cables, which has become the main means for various enterprises to improve their market competitiveness. However, the continuous improvement of production speed has caused the problem of unstable sheath quality, and the sheath is prone to defects, such as bulges, concave ponds, uneven thickness, etc. Other defects can be found through inspection, and bulge defects currently rely on operators in China. Eyes and hands are used to identify, and the production line speed is very fast (generally more than 60 m / min), which is almost out of control. As a result, the product may be unqualified and scrapped, or even the unqual...

Problems solved by technology

However, the continuous improvement of production speed has caused the problem of unstable sheath quality, and the sheath is prone to defects, such as bulges, concave ponds, uneven thickness, etc. Other defects can be found through inspection, and bulge defects currently rely on operators in China. Eyes and hands are used to identify, and the production line speed is very fast (generally more than 60 m / min), which is almost out of control. As a result, the product may be unqualified and scrapped, or even the unqualified product is sent to the customer, resulting in market loss and huge losses.

[0003] There are high-end online defect detection equipment abroad, which can detect the quality of the optical cable sheath through electronic application technology, but the price is expensive and not economical. In addition, the imported equipment has high environmental requirements. For example, the moisture on the surface of the sheath must be completely dried, otherwise it is easy to produce defects. Misjudgment, the voltage must be very stable, otherwise it will not only cause misjudgment, but also cause equipment damage
