[0002] The wettability of glass fiber is its key indicator. Glass fiber fabrics with good wettability can better bond with the resin matrix, greatly improving the reliability and quality consistency of the board and improving production efficiency. The traditional method for testing the wettability of glass fiber is mainly through the "bull's eye method", that is, drawing a target-like line on white paper, placing the sample to be tested flat on the paper, dropping a certain amount of resin or glue on the bull's eye, and recording the time for the bull's eye and lines to appear to determine the penetration speed of different glass fibers in the resin glue. However, this method has the problem of difficulty in determining a unified standard for the clarity of the lines, resulting in inaccurate measurement results.

[0003] Some technicians in the industry have used the changes in the "transmittance" data of the transmittance detector to determine the penetration speed of glass fiber. That is, during the penetration process of the sample to be tested, a large amount of "transmittance" test value data and the corresponding time are recorded, and then the penetration speed of the sample is determined by data aggregation and curve fitting. However, this method has the problems that the test process requires personnel to track the entire process, the degree of automation is low, the spraying position and amount of glue are manually judged and controlled, and are greatly affected by human factors.

The light emitted by the light source emitting and data recording unit 112 passes through the detection platform and the mobile platform 120 in sequence and is received by the light source receiving unit 113.

[0037] The mobile platform 120 is disposed on the detection platform of the detector 110. The mobile platform 120 is used to place the sample to be detected.

Figure 2 As shown, the mobile platform 120 includes a first plate 121, a second plate 122 and a third plate 123 stacked in sequence from top to bottom.

[0038] The bottom surface of the first plate 121 is provided with a first sliding group 1211, and a first sliding rail (not shown in the figure) is provided on the top surface of the second plate 122 along a first preset direction. The first sliding group 1211 is slidably connected to the first sliding rail.

The glue injection is controlled by the control component 300, so that the glue spraying position and the glue spraying amount are more stable and accurate, which solves the problem that the glue spraying position and the glue spraying amount during the current test are manually judged and controlled and are greatly affected by human factors.

[0042] like Figure 4 As shown, the heating sleeve 220 is used to heat the glue in the glue sprayer 210. The heating sleeve 220 is connected to the control component 300 by signal, and the glue sprayer 210 is sleeved in the heating sleeve 220. The heating sleeve 220 includes a heating body 221 and a buckle 222. The heating body 221 is an open cylindrical structure for easy insertion of the glue sprayer 210. The buckle 222 is arranged on the heating body 221. The opening of the heating body 221 is locked by the buckle 222 to ensure that the inner wall of the heating body 221 is closely attached to the outer wall of the glue sprayer 210, so that it can quickly transfer heat. By setting the heating sleeve 220, the glue in the glue sprayer 210 will not cool and solidify, ensuring the uniform viscosity of the glue during the detection process.

[0043] like Figure 5 As shown, the first end of the telescopic rod 140 is provided with a mounting hole 141, and the side wall of the heating sleeve 220 is provided with a mounting rod 223, and the mounting hole 141 and the mounting rod 223 are detachably connected to connect the heating sleeve 220 to the telescopic rod 140. A ball joint bearing 142 is also provided at the first end of the telescopic rod 140, and the mounting hole 141 is provided on the ball joint bearing 142. The ball joint bearing 142 is provided so that the first end of the telescopic rod 140 can rotate in a wide range, so as to adjust the glue spraying position of the glue sprayer 210.

[0044] like Figure 6 As shown, the second end of the telescopic rod 140 is provided with a rack 143, and the column 111 is provided with a gear shaft 1111, the gear shaft 1111 is gear-connected with the rack 143, the telescopic rod 140 is signal-connected with the control component 300, and the gear shaft 1111 is also signal-connected with the control component 300. The telescopic rod 140 is extended and retracted by the interval rotation of the gear shaft 1111, thereby realizing the extension and retraction of the glue sprayer 210 in the heating sleeve 220.

[0045] return Figure 1 In the embodiment, the compressed air pump 230 is connected to the switch 240, the switch 240 is connected to the glue sprayer 210, and the compressed air pump 230 and the switch 240 are respectively connected to the control component 300 by signal. The compressed air pump 230 is used to generate compressed air, and the switch 240 is used to control the stable output of the gas generated by the compressed air pump 230 to the glue sprayer 210, so that the glue sprayer 210 has a stable output driving force, and the compressed air is stably driven to control the glue sprayer 210 to spray quantitatively.

[0046] The control component 300 may be a PC integrated system, including a computer and a software program, and the software program may include command parameters such as inputting the number of samples to be tested, inputting the test interval time, starting, ending, etc. The control component 300 controls the above-mentioned related structures connected to the signal, and realizes the automation of the detection equipment through the software program control, thereby improving the automation of the glass fiber wetting performance detection. At the same time, the control component 300 receives the light transmission detection data of the detector 110, generates the wetting performance report of the sample to be tested, realizes the real-time update, summary, and curve fitting of the detection data, and does not need to manually process the cumbersome post-data, thereby reducing the data processing time and manual labor intensity.

[0047] The following is a detailed description of the working principle of the detection equipment in this application through a specific detection process:

[0048] 1) Preheating; the control component 300 controls the heating sleeve 220 to start the constant temperature heating function. After a period of time, the glue is stabilized within a required viscosity value range.

[0049] 2) Setting parameters: Setting the number of samples to be tested and the test interval time through the control component 300.

[0050] 3) Preparation of samples to be tested; laying the mold plate 130 in the hollow groove of the mobile platform 120, then laying a layer of high-transmittance film, and then laying the sample to be tested, and finally laying another mold plate 130 to fix the sample to be tested, and aligning the position with the lower mold plate 130.

[0051] 4) Detection; start the compressed air pump 230, input the compressed air to the switch 240, the switch 240 sets the output pressure value, realizes the voltage-stabilized output, and ensures that the volume of compressed air output each time is consistent; the control component 300 controls the mobile platform 120 to start moving, and at the same time controls the telescopic rod 140 to extend, so that the glue outlet of the glue sprayer 210, the first detection hole 131, and the light source emission port are in a straight line, and then controls the glue sprayer 210 to quantitatively spray glue on the sample to be detected in the first detection hole 131; after the glue spraying is completed, the telescopic rod 140 is controlled to extend. 0 is retracted, and the glue sprayer 210 leaves the detection area to avoid blocking the light source receiving part 113. At the same time, the light source emission and data recording part 112 starts to record the detection data and recording time, and sends them to the software program control of the control component 300. After continuously testing multiple "transmittance" data, the detection of the first sample to be detected is completed; the control component 300 controls the movement of the mobile platform 120 to move the second detection hole 131 above the light source emission port, and restarts a new round of detection. The above steps are repeated until the detection of all samples to be detected is completed.

[0052] 5) Report generation and export; after confirming that there is no need to add samples to be tested, the test is controlled to end, the mobile platform 120 returns to the starting position, and the control component 300 automatically fits the curve and generates a report; if it is necessary to continue to add samples to be tested, the software program can be used to control the increase in tests, and the number of tests can be entered, and the test can be started again.

[0053] In summary, the detection equipment of the present application utilizes a compressed air pump and a switch to drive the glue sprayer, and combines a heating sleeve to control the viscosity of the glue liquid, thereby realizing quantitative spraying of the glue liquid and ensuring the stability and accuracy of the glue spraying; utilizing a sliding combination between multiple steel plates to realize the planar movement of the mobile platform, so that the detection equipment can perform continuous detection; at the same time, utilizing software programming to integrate the control of the switch, the transmittance detector, the mobile platform, and the control of the position movement of the glue spraying device, thereby forming an effective detection closed loop, realizing the automation of the detection process, reducing manual labor time, and being able to continuously and batch-wise detect multiple samples to be detected, thereby realizing automatic data processing.
