Description

[0002] Low dielectric glass fiber cloth is a special glass fiber material with excellent dielectric properties. It has a low dielectric constant and dielectric loss, which makes it have better performance in high-frequency circuits and microwave transmission, and can effectively reduce the attenuation and distortion during signal transmission. Low dielectric glass fiber cloth also has good temperature resistance and thermal insulation properties, can remain stable in high temperature environments, has good corrosion resistance to a variety of chemicals, and is suitable for a variety of harsh environments. Therefore, low dielectric glass fiber cloth is often used in the electronics industry, communications field, construction industry, power industry, aerospace industry and other fields. The warp and weft density detection of low dielectric glass fiber cloth is one of the important indicators for evaluating its quality.

[0003] The Chinese patent document with the authorization announcement number CN112229840B discloses a latitude and longitude detection device for glass fiber cloth research and development, including a support mechanism, a counting mechanism and an observation mechanism. The support mechanism includes a base plate, an anti-skid component and a slider, a through hole is provided in the middle of the base plate, and the through hole is a rectangular through hole, and both sides of the upper surface of the base plate are provided with a slide groove, and the cross section of the slide groove is set as a T-shaped structure, the anti-skid component is fixedly connected to the lower surface of the base plate, and the slider is slidably set in the slide groove; the counting mechanism includes a support plate, a limit rod, a knob assembly, a rotating rod, a moving block and a counting needle, the support plate is fixedly connected to the upper side of the slider, the knob assembly is set on one side of the support plate, and one end of the rotating rod is fixedly connected to one side of the knob assembly.

[0004] The above-mentioned glass fiber cloth longitude and latitude detection technology has the following shortcomings: 1. The cloth is only pressed by the bottom plate to position it, but the bottom plate is not fixed. During the detection process, it is easy to be affected by external force or operational problems of the detection personnel, causing the bottom plate to move, which will not only cause the low-dielectric glass fiber cloth to deform, but also change the detection range, affecting the accuracy of longitude and latitude detection. 2. It is necessary to rely on manual counting to obtain the number of warp and weft threads of the low-dielectric glass fiber cloth. The detection process is prone to miscounting and missing numbers. Not only is the detection efficiency low, but the detection data is also prone to errors. Summary of the invention

The table top of the testing platform 1 is connected to the top seat 4 through the supporting column 3, and the table top and the top seat 4 are opposite to each other, and the inside of the testing platform 1 is hollow; the limiting component 2 is arranged on the testing platform 1, and the upper and lower ends are provided with limiting ends for limiting the flat laying of the low dielectric glass fiber cloth, and the two sets of limiting ends can be adjusted by rotating the origin and turning the whole; the gluing component 9 is arranged in the hollow of the testing platform 1, and the flat laying limiting of the low dielectric glass fiber cloth is assisted by gluing the upper limiting end; the testing component 5 is driven by the cylinder 6 to rise and fall between the top seat 4 and the limiting component 2; the testing component 5 includes two groups of testing parts 504; the two groups of testing parts 504 respectively make reverse reciprocating movements along parallel tracks, and the testing end rises and falls synchronously with the ups and downs of the yarn during the movement, and automatically records the number of yarns in the warp and weft directions of the low dielectric glass fiber cloth below, so as to perform longitude and latitude detection on the low dielectric glass fiber cloth.

[0030] like Figure 3As shown, the table top of the test bench 1 includes a mounting seat 101 with an opening 103 and a mounting outer edge 102 arranged around the mounting seat 101; the opening 103 is connected to the hollow inside the test bench 1; the limit assembly 2 is rotatably arranged on the opening 103 to exchange the positions of the upper and lower limit ends. The upper limit end is used for the limit of the low dielectric glass fiber cloth and the longitude and latitude detection, and the lower limit end is used for waiting for glue coating.

[0031] like Figure 4 As shown, the support column 3 is arranged on the mounting outer edge 102, and a guide groove 301 is arranged thereon to guide the lifting and lowering of the detection component 5; one end of the guide rod 10 slides along the guide groove 301, and the other end is connected to the detection component 5; the support column 3 can not only support and stabilize the top seat 4, but also guide the lifting and lowering of the detection component 5.

[0032] like Figure 5-Figure 6 As shown, the limit assembly 2 includes a flip disk 201 that is driven by a driving member and flipped up and down in the opening 103; rotatable turntables 202 are provided at the upper and lower ends of the flip disk 201; limit platforms 203 are provided on the two groups of turntables 202 in a one-to-one correspondence, and the limit platforms 203 are the limit ends; and the fixing ring 204 is detachably provided on the outer periphery of the limit platform 203.

[0033] It should be further explained that the driving member 1 includes a rotating shaft located on the central axis of the flip disk 201; the gear 1 207 is keyed to the rotating shaft; the gear 2 208 is driven to rotate by the motor 1 209 and is meshed with the gear 1 207, thereby driving the flip disk 201 to flip.

[0034] It should be further explained that the turntable 202 is driven by the second motor and rotates at the center origin of the flip disk 201 .

[0035] It should be further explained that the limit platform 203 is set at the center of the turntable 202; a clamping hole 206 is set on the outer periphery of the turntable 202; a clamping rod 205 matching the clamping hole 206 is set on the large circle opening on one side of the fixed ring 204, and the small circle opening on the other side is used to surround the limit platform 203.

[0036] Before testing, it is necessary to lay a low-dielectric glass fiber cloth slightly larger than the limit platform 203 flat on the limit platform 203 coated with glue, and then clamp the limit platform 203 with the fixing ring 204 through the clamping hole 206 and the clamping rod 205 to position the periphery of the low-dielectric glass fiber cloth. After the fixing is completed, the limit platform 203 is driven to rotate by rotating the turntable 202, and the warp and weft directions of the low-dielectric glass fiber cloth are adjusted to match the moving detection trajectory of the detection piece 504. After a round of testing is completed, the flip disk 201 can be flipped over and the glue-coated limit platform 203 below is replaced to face upward.

[0037] like Figure 7-Figure 8As shown, the glue coating component 9 includes a glue storage box 901 located inside the testing platform 1; the glue storage box 901 is provided with an inlet and outlet sleeve 902 opposite to the opening 103; the glue outlet pipe is located in the inlet and outlet sleeve 902, the upper end of which extends out of the glue storage box 901 and is connected to the glue coating seat 904 on the lifting seat 903, and the lower end extends into the glue storage box 901 and is connected to a glue pump 1; the lifting seat 903 is driven by a driving member 2 to rise and fall between the glue storage box 901 and the limiting component 2.

[0038] It should be further explained that the driving component 2 includes two sets of guide rails 907 located on both sides of the inlet and outlet sleeve 902 and arranged along the length direction of the glue coating seat 904; each set of guide rails 907 is provided with a screw 909 driven to rotate by motor 3; two sets of transmission rods 908 are provided corresponding to the two sets of guide rails 907, and one end of each set of transmission rods 908 is rotatably connected to the glue coating seat 904 through the upper connecting block, and the other end is threadedly connected to the corresponding screw 909 through the lower rotating block.

[0039] like Figure 7-Figure 8 As shown, the glue coating seat 904 is driven by the driving member 3 and is rotatably set on the lifting seat 903. The glue outlet hole 906 and the glue scraper frame 905 are set at the upper end of the glue coating seat 904. A through groove 912 for installing the driving member 3 is set in the middle of the lower end of the glue coating seat 904. Glue storage chambers 911 connected to the glue outlet pipe and the glue outlet hole 906 are set on both sides of the glue coating seat 904; and a glue pump 2 connected to the glue outlet hole 906 is set in the glue storage chamber 911.

[0040] It should be further explained that the driving member three includes a gear three 910 located in the through groove 912 and connected to the lifting seat 903; the motor four 914 is located on the glue coating seat 904, and the main shaft is connected to the gear four 913; the gear four 913 is connected to the gear three 910 through meshing, thereby driving the entire glue coating seat 904 to rotate.

[0041] It should be further explained that the connecting tube 915 movably passes through the tooth core of the gear three 910 , the lower end is connected to the glue outlet pipeline, and the upper end is connected to the glue storage chamber 911 .

[0042] Before testing, flip the limit platform 203 on the standby side to face downward. The lead screw 909 rotates, driving the two sets of lower rotating blocks to move relative to each other, and the transmission rod 908 rotates, pushing the lifting seat 903 to move upward, and the glue outlet pipe extends along the inlet and outlet sleeve 902 until the glue scraping frame 905 fits the limit platform 203. Driven by the motor 4 914, the gear 4 913 is meshed and connected to the gear 3 910, thereby driving the entire glue coating seat 904 to rotate. The glue pump 2 draws the glue in the glue storage chamber 911 into the glue outlet hole 906. The glue scraping frame 905 evenly applies the glue on the limit platform 203. When the amount of glue in the glue storage chamber 911 is insufficient, the glue pump 1 transfers the glue in the glue storage box 901 to the glue storage chamber 911 for replenishment.

[0043] It should be further explained that the limiting platform 203 is arranged in the groove of the turntable 202 by magnetic attraction, and a heating layer is arranged on the glue-coated end of the limiting platform 203; the glue is a thermosetting resin adhesive.

[0044] Thermosetting resin adhesive is a hardening material commonly used in glass fiber products. After the resin is coated on the limit table 203 and covered with glass fiber cloth, it can be heated and cured to harden the glass fiber cloth. During the detection process, the low-dielectric glass fiber cloth can maintain its flat and stiff state so that the detection part 504 can work. The limit table 203 is fixed by magnetic attraction. After a set of detection is completed, it can be removed and cleaned, and a clean limit table 203 can be quickly replaced.

[0045] like Figure 5 As shown, a laser emitting plate 8 and a laser receiving plate 7 are arranged around the opening 103 on the mounting seat 101; two pairs of laser emitting plates 8 and laser receiving plates 7 are arranged, and the positions of the laser emitting plates 8 and laser receiving plates 7 in each pair are opposite; the detection light between one pair of laser emitting plates 8 and laser receiving plates 7 is used to detect the warp direction of the dielectric glass fiber cloth, and the detection light between the other pair of laser emitting plates 8 and laser receiving plates 7 is used to detect the weft direction of the dielectric glass fiber cloth. The two groups of detection light are perpendicular to each other and are arranged in parallel above the limit assembly 2; the moving direction of the two groups of detection members 504 is consistent with the direction of one group of detection light.

[0046] Before the test, the direction of the warp and weft of the low dielectric glass fiber cloth is checked by emitting a test light. The turntable 202 is rotated to adjust the angle of the low dielectric glass fiber cloth so that the direction of the warp and weft correspond to the two sets of test light. In other words, the direction of the warp and weft of the low dielectric glass fiber cloth matches the test direction of the test piece 504. After the warp is tested, the weft can be tested by rotating the turntable 202 ninety degrees.

[0047] like Figure 9-10 As shown, the detection component 5 includes a detection cover 501 connected to the telescopic end of the cylinder 6; the cover opening of the detection cover 501 faces the limit assembly 2, and multiple groups of drive boxes 502 are arranged in parallel and at intervals inside the detection cover 501; a drive member four is arranged in the drive box 502; two groups of detection members 504 are slidably arranged between two adjacent groups of drive boxes 502, and are driven by the drive members four on both sides to make synchronous, reverse and parallel movements.

[0048] It should be further explained that a circle of anti-slip frame 505 is arranged on the cover opening of the detection cover 501, which produces an anti-slip effect when in contact with the low-dielectric glass fiber cloth, further improving the stability of the low-dielectric glass fiber cloth.

[0049] It should be further explained that three groups of driving parts 4 are arranged corresponding to the driving box 502, each group includes a transmission chain 503; the transmission chain 503 is driven by an electric roller and rotates in the driving box 502; the transmission chains 503 on both sides rotate in the same direction and opposite to the rotation direction of the middle transmission chain 503.

[0050] like Fig.11 As shown, the detection member 504 includes a detection box 50401 slidably set between two groups of driving boxes 502; the detection box 50401 is connected to the transmission chains 503 on both sides through the slider 50402, and a driving member five is set at the same time; three groups of detection cylinders 50405 are arranged side by side, the middle group of detection cylinders 50405 is fixedly set at the bottom of the detection box 50401, and the two groups of detection cylinders 50405 on both sides are driven by the driving member five and are respectively slid in opposite directions at the bottom of the detection box 50401; a spring 50406 is set at the top end of each group of detection cylinders 50405; the detection rod 50407 is slidably set on the lower end of the detection cylinder 50405, a displacement sensor 50408 is set at the upper end and connected to the spring 50406, and a moving wheel 50409 is set at the lower end; the moving wheel 50409 is the detection end.

[0051] It should be further explained that the driving member 5 includes a lead screw 2 50403 driven to rotate by a motor 5; two groups of moving blocks 50404 are threadedly connected to the two ends of the lead screw 2 50403; and two groups of detection cylinders 50405 on both sides are connected to the moving blocks 50404 one by one.

[0052] It should be further explained that the threads at both ends of the lead screw 50403 are opposite.

[0053] Before detection, the spacing of the three groups of detection cylinders 50405 is adjusted by moving the two groups of detection cylinders 50405 on both sides (together or away) to match the spacing of adjacent warps or adjacent wefts of the low dielectric glass fiber cloth. For example, when detecting longitude, it is necessary to move the moving wheel 50409 in the direction of the weft while avoiding the weft. The moving wheel 50409 descends when entering the mesh and rises when leaving the mesh and encountering the warp, thereby forming an undulating moving trajectory. The detection rod 50407 moves up and down along the undulating trajectory, and the displacement sensor 50408 records the displacement data and converts the displacement into the number of yarns in the warp or weft direction to determine the longitude and latitude. Due to the synchronous, reverse, and parallel movement of the two groups of detection members 504, and the synchronous movement of the three groups of moving wheels 50409, multiple groups of detection data can be obtained in one detection to improve the accuracy of longitude and latitude judgment.

[0054] It should be further explained that air jet seats 50411 are provided on both sides of the detection box 50401; the air jet seats 50411 take in air through an air pump and spray air downward through a nozzle 50410; during the detection process, the nozzle 50410 sprays high-pressure gas downward to clean the low-dielectric glass fiber cloth and reduce detection interference.

[0055] Embodiment 2: Based on the dielectric glass fiber cloth longitude and latitude detection device in Embodiment 1, this embodiment proposes a low dielectric glass fiber cloth longitude and latitude detection method, and the steps are as follows:

[0056] S1, the lead screw 909 rotates, driving the two sets of lower rotating blocks to move relative to each other, the transmission rod 908 rotates, pushing the lifting seat 903 to move upward, and the glue outlet pipe extends along the inlet and outlet sleeve 902 until the glue scraping frame 905 fits the limit table 203; driven by the motor 4 914, the gear 4 913 is meshed and connected with the gear 3 910, thereby driving the entire glue coating seat 904 to rotate; the glue pump 2 draws the glue in the glue storage chamber 911 into the glue outlet hole 906; the glue scraping frame 905 evenly applies the glue on the limit table 203;

[0057] S2, the glue-coated limiting platform 203 is turned upward, and the low-dielectric glass fiber cloth slightly larger than the limiting platform 203 is laid flat on the glue-coated limiting platform 203, and then the limiting platform 203 is clamped with the fixing ring 204 through the clamping hole 206 and the clamping rod 205 to position the periphery of the low-dielectric glass fiber cloth;

[0058] S3, the limit table 203 heats and cures the glue to harden the glass fiber cloth;

[0059] S4, emitting two groups of detection light beams, and by rotating the turntable 202, correcting the angle of the low-dielectric glass fiber cloth so that the longitude and latitude directions thereof correspond to the two groups of detection light beams respectively, thereby matching the detection direction of the detection element 504;

[0060] S5. The detection cylinders 50405 on both sides are moved (closer or farther away), and the spacing between the three groups of detection cylinders 50405 is adjusted to match the spacing between adjacent longitudes or adjacent latitudes of the low dielectric glass fiber cloth; for example, when detecting longitude, the moving wheel 50409 needs to be moved along the latitude direction while avoiding the latitude; the detection cover 501 is lowered to press the dielectric glass fiber cloth to position its periphery;

[0061] S6, the driving member 4 drives the two groups of detection members 504 to move synchronously, in the opposite direction and in parallel. During the movement, the multiple groups of moving wheels 50409 descend when entering the mesh, and rise when leaving the mesh and encountering the warp, thereby forming an undulating movement trajectory; the corresponding detection rod 50407 moves up and down along the undulating trajectory, and the displacement sensor 50408 records the displacement data and converts the displacement into the number of warp yarns;

[0062] S7, the low dielectric glass fiber cloth is turned 90 degrees, and the angle of the low dielectric glass fiber cloth is corrected again, and the two sets of detection components 504 repeat the work to automatically record the number of weft yarns of the low dielectric glass fiber cloth below;

[0063] S8. Combining the number of warps and wefts of the low dielectric glass fiber cloth within a unit area, a set of longitude and latitude detection results of the low dielectric glass fiber cloth is obtained;

[0064] S9, remove the detected limit platform 203, replace it with a new limit platform 203, and at this time, the lower limit platform 203 is glued synchronously, and the second set of detection work begins.

[0065] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
