Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber cloth detection equipment, in particular to a glass fiber fabric warp and weft density measuring device. Background Art

[0002] Glass fiber cloth is an important electronic raw material. Glass fiber cloth is used as a reinforcing material, impregnated with resin, and covered with copper foil on one or both sides. It can be processed into copper clad laminates by hot pressing. Copper clad laminates are one of the materials for producing circuit boards. The measurement of warp and weft density is an important process in the production of glass fiber. In the production process of glass fiber cloth, there are strict requirements for its warp and weft density. Since the existing measuring equipment generally increases the brightness on the side through mobile light sources such as flashlights, there will be shadow areas, which is inconvenient. Moreover, it is not easy to measure the warp and weft density of glass fiber cloth after it is coated with resin solvent. Therefore, patent CN214224072U proposes "a glass fiber fabric warp and weft density measuring device". By setting up lighting components and moving mechanisms, it is not necessary to frequently adjust the position of the mobile light source during measurement, thereby improving the detection efficiency, and no shadow areas will be generated, thereby improving the detection efficiency.

[0003] However, in this solution, since the L-shaped fixing plate and the transparent plate are fixedly connected, the warp and weft density measuring component cannot be moved at will. It is necessary to frequently move the fabric position to cooperate with the measuring component of the equipment to ensure the measurement accuracy, which reduces the measurement efficiency. Therefore, a glass fiber fabric warp and weft density measuring device is proposed. Utility Model Content
