[0002] The electronic-grade glass fiber cloth is an essential basic material for the copper-clad laminate (CCL) and printed circuit board (PCB) industries, and its performance determines the electrical properties, mechanical properties, dimensional stability and other important properties of CCL and PCB to a great extent.

[0003] In recent years, with the development of lightweight electronic information products, especially the application of circuit boards on mobile phones and mobile PCs, the circuit board lines are quite close and fine, and the paths between the lines and the holes on the circuit board are smaller. When laser drilling, if there is a hollow glass fiber (i.e., the glass fiber has a hole structure), subsequent copper infiltration will cause the circuit board to short circuit and fail (CAF failure). In addition, with the rise of artificial intelligence and intelligent driving, the circuit boards applied in automobile computer control systems are more demanding. Therefore, it is necessary to accurately detect the glass fiber. The existing detection method is benzyl alcohol immersion detection. A strong light flashlight is used to irradiate the light along the horizontal direction perpendicular to the warp and weft yarns (the horizontal and vertical directions of the glass fiber). The moving range is large, the visible range is small, and only the bright part of the light can correctly distinguish the hollow yarn of the glass fiber. The detection of the full-width glass fiber cloth sample requires left-right and up-down movement, which is time-consuming and labor-intensive, and seriously affects the detection efficiency.

The light strip can be slidably adjusted and installed along the vertical direction of the glass tank.

[0007] Further, the sliding rail mechanism includes a positioning sliding rail installed on the light shield and a guide sliding block used in cooperation with the positioning sliding rail. The guide sliding block is fixedly installed at the end face in cooperation with the light strip, and the guide sliding block moves to drive the light strip to move synchronously.

[0008] Further, the light band is in a rectangular shape as a whole and is sleeved on the glass tank in a circumferential direction, and the guide sliding blocks are arranged in a plurality of and are distributed on the light band at intervals.

[0009] Further, the light shield includes a light shield stand and a light shield plate which is bent on the light shield stand, and the light shield plate extends to above the glass tank.

[0010] Further, the glass tank is filled with benzyl alcohol detection solution.

[0011] Further, the light shield is provided with a plurality of positioning sliding rails, and the plurality of positioning sliding rails are used in cooperation with the plurality of guide sliding blocks.

[0012] The glass fiber detection device has the advantages that the light band can be adjusted in the vertical direction of the glass tank through the sliding rail mechanism arranged on the light shield and cooperating with the light band, the irradiation position is controlled better, the light source intensity around the glass tank is consistent, the warp and weft directions of the measured sample can be observed at the same time, the product defects are obvious at a glance, and the detection efficiency is improved.
