Abstract
Description
Technical Field
[0001] This utility model relates to the field of semi-cured sheet weft skew measurement technology, specifically to a device for inspecting the weft skew of glass fiber cloth in semi-cured sheets. Background Technology
[0002] As smartphones, wearable devices, 5G communications, servers, switches, and other products continue to pursue thinner, lighter, and higher-performance requirements, the quality standard for PCB warpage has been tightened from <0.75% in the industry to <0.5%, with some high-density electronic components requiring PCB warpage of <0.3%. To meet these warpage quality requirements, the warpage of copper-clad laminates and prepregs has also become more stringent, with the skewness of the prepreg being a significant factor affecting the warpage of both.
[0003] Prepreg is composed of fiberglass cloth, resin, and fillers. The fiberglass cloth is often simply called glass cloth. After adding fillers to the resin, glass is immersed in the resin, and then the resin is squeezed to evenly coat the glass cloth. Finally, it is dried to complete the manufacturing process. The glass cloth is white, while the resin comes in various colors with significant color variations. However, once the glass cloth is coated with resin, it cannot be visually inspected, and it's impossible to confirm whether the glass cloth has developed a skew during processing. The industry commonly uses a method of manually outlining the glass cloth and then measuring the skew using a semicircular measuring instrument. This method is inefficient and its accuracy is easily affected by the operator's skill in drawing the outline. Utility Model Content
[0004] The purpose of this invention is to provide a device for inspecting the weft skew of semi-cured glass fiber cloth, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the weft skew of semi-cured glass fiber cloth, comprising: An inspection base is provided, in which multiple parallel lights are installed, and a flat glass plate is provided above the multiple parallel lights. A displacement assembly is located above the flat glass. The displacement assembly includes a sliding plate, a first slide rail, and a second slide rail. The sliding plate is slidably mounted on the first slide rail and the second slide rail. An electric motor for driving the sliding plate to move is installed on the sliding plate. A CCD lens, wherein the CCD lens is mounted on a skateboard; The computer processing unit is electrically connected to the CCD lens.
[0006] Furthermore, a light groove is provided on the upper side of the inspection base, and multiple parallel lights are nested in the light groove, with the flat glass installed at the opening of the light groove.
[0007] Furthermore, the second slide rail is arranged parallel to the first slide rail, and a rack is fixed on the side of the second slide rail away from the first slide rail. The output end of the electric motor rotates through the slide plate and is connected to a gear. The gear meshes with the rack. By adopting the meshing transmission method of gear and rack, the electric motor can accurately control the movement of the slide plate, ensuring the uniform movement of the CCD lens and improving the stability and consistency of image acquisition.
[0008] Furthermore, support rods are installed at the four upper corners of the inspection base. The left and right ends of the first and second slide rails are connected to connecting plates. A collar is fixed to the connecting plate at the position of the corresponding support rod, and the collar is sleeved on the corresponding support rod.
[0009] Furthermore, the side wall of the collar is threaded with a locking knob, the tail end of which abuts against the outer wall of the support rod. By tightening the locking knob, the displacement component can be firmly fixed on the support rod, further improving the stability and reliability of the device. At the same time, the height of the displacement component can be adjusted, thereby adjusting the distance between the CCD lens and the flat glass.
[0010] Furthermore, a support base is fixed to the front side of the inspection base, and the computer processing terminal is mounted on the support base.
[0011] Furthermore, the computer processing unit is equipped with color processing software and size measurement software. Through software processing, automated data processing and analysis can be achieved, reducing manual intervention and improving the accuracy of detection.
[0012] Furthermore, a control panel is installed on the front side of the inspection base. The control panel is electrically connected to the parallel lamp, the electric motor, and the CCD lens.

The displacement assembly is located above the flat glass 3. The displacement assembly includes a slide plate 4, a first slide rail 5, and a second slide rail 6. The slide plate 4 is slidably mounted on the first slide rail 5 and the second slide rail 6. An electric motor 7 that drives the slide plate 4 to move is mounted on the slide plate 4. CCD lens 8, CCD lens 8 is mounted on slide plate 4; Computer processing terminal 9 is electrically connected to CCD lens 8.

[0020] The second slide rail 6 is set parallel to the first slide rail 5. A rack 11 is fixed on the side of the second slide rail 6 away from the first slide rail 5. The output end of the electric motor 7 rotates through the slide plate 4 and is connected to a gear 12. The gear 12 meshes with the rack 11. By using the meshing transmission method of the gear 12 and the rack 11, the electric motor 7 can accurately control the movement of the slide plate 4, ensuring the uniform movement of the CCD lens 8 and improving the stability and consistency of image acquisition.
[0021] Support rods 13 are installed at the four upper corners of the inspection base 1. The left and right ends of the first slide rail 5 and the second slide rail 6 are connected to the connecting plate 14. The connecting plate 14 is fixed with a collar 15 corresponding to the position of the support rod 13. The collar 15 is sleeved on the corresponding support rod 13.
[0022] The side wall of the collar 15 is threaded with a locking knob 16. The tail end of the locking knob 16 abuts against the outer wall of the support rod 13. By tightening the locking knob 16, the displacement component can be firmly fixed on the support rod 13, which further improves the stability and reliability of the device. At the same time, the height of the displacement component can be adjusted, thereby adjusting the distance between the CCD lens 8 and the flat glass 3.
[0023] A support base 17 is fixed to the front side of the inspection base 1, and a computer processing terminal 9 is installed on the support base 17.

The parallel light 2 is activated via the control panel 18 to provide a uniform light source for testing. The electric motor 7 is activated, driving the slide plate 4 to move on the first slide rail 5 and the second slide rail 6, which in turn drives the CCD lens 8 to move uniformly from left to right. During the movement, the CCD lens 8 captures the graphic outline of the glass cloth in the semi-cured material and transmits the captured graphic outline to the computer processing terminal 9. The computer processing terminal 9 uses color processing software to filter out the resin color and deepen the color of the glass cloth to make its outline clear. The slant of the warp and weft threads of the glass cloth is measured using size measurement software, and the slope of the glass cloth is calculated. This greatly improves the testing efficiency, saves time and labor costs, and improves the accuracy of the testing.
