[0002] With the development of science and technology, intelligent electronic equipment develops towards smaller and thinner, which means that a same or even higher number of chips needs to be installed on a smaller substrate, so the circuit on the substrate will be more dense and the wiring distance will be smaller. As the skeleton layer of the substrate, the glass fiber cloth must have good insulation performance to prevent short circuit, which requires the glass fiber cloth to have few or even no broken filaments. This will be the future development trend of glass fiber cloth.

[0003] Since a glass yarn is composed of multiple glass fibers, some glass fibers will break due to the friction of the yarn guide part during production, thereby generating broken filaments on the surface of the glass yarn. During weaving, the broken glass yarn is subjected to air flow impact and reed beating, thereby forming weft breakage abnormalities on the cloth surface. The produced glass fiber cloth cannot meet the production requirements of high-end products. SUMMARY

[0006] Preferably, the guide roller assembly comprises a first guide roller, a second guide roller, and a third guide roller.

[0007] Preferably, the weft yarn is wound on the first guide roller, the second guide roller, and the third guide roller in sequence.

[0008] Preferably, the detection assembly is arranged between the second guide roller and the third guide roller.

[0009] Preferably, the detection assembly comprises a high-strength camera and an illumination light source.

[0010] The utility model discloses beneficial effect lies in: the utility model discloses can effectively reduce the weft broken defect of cloth face, promote cloth face quality;Weft broken silk exception does not need manual supervision, can continuous 24h computer monitoring, and the monitoring effect is guaranteed;Exceptional weft finds without manual processing, can automatic processing and starting, promote production efficiency.
