Abstract
Description
Technical Field
[0001] This application relates to the field of automotive interiors, and more specifically, to a composite fabric structure that enables rapid identification of positioning joints. Background Technology
[0002] Automotive interior composite fabrics are typically made by layering and laminating an outer layer, sponge, and base fabric. During the sponge raw material supply and lamination process, the formation of sponge joints is difficult to avoid. However, after the lamination process is completed, relying solely on manual visual observation and tactile perception is insufficient to accurately identify these sponge joints. This inspection method has significant limitations, failing to effectively detect and identify sponge joint problems. The direct consequence is that substandard products enter the market, severely impacting the overall product quality. Utility Model Content
[0003] The purpose of this invention is to solve the defect in the prior art that splicing joints cannot be accurately identified. To this end, this application discloses a composite fabric structure that can quickly identify and position joints.
[0004] To achieve the above-mentioned objectives, this application adopts the following technical solution:
[0005] This application provides a composite fabric structure for quickly identifying and positioning joints, comprising a top layer, a sponge layer, and a bottom layer stacked sequentially, wherein a metal marker is embedded at the joint of the sponge layer.
[0006] Furthermore, an adhesive layer is also included between the surface layer and the sponge layer.
[0007] Furthermore, the metal marker is a fine aluminum wire, a soft copper wire, or an aluminum foil tape.
[0008] Furthermore, the diameter of the fine aluminum wire is 0.3~1mm, and the implantation depth is 1 / 3~2 / 3 of the thickness of the connector.
[0009] Furthermore, the metal marker is aluminum foil tape, which includes an aluminum foil layer and a high-temperature resistant adhesive backing layer, and the width of the aluminum foil tape is 5~10mm.
[0010] Furthermore, the surface of the metal marker is covered with an insulating coating with a thickness of 0.01~0.03mm.
[0011] Furthermore, the base fabric layer is provided with conductive yarns, and the arrangement direction of the conductive yarns forms an angle of 45° to 90° with the extension direction of the metal marker.
[0012] Furthermore, the metal markers are arranged in a wavy or serrated pattern.
[0013] Furthermore, the metal marker is composed of segments made of different metal materials, with a gap of 0.5 to 2 mm between adjacent segments, including an alternating arrangement of aluminum and copper segments.
[0014] In summary, this application has the following beneficial effects:
[0015] 1. This application can quickly locate the joint position using a metal detector, solving the problems of low efficiency and high missed detection rate of manual inspection.
[0016] 2. This application uses fine aluminum / soft copper wire with a diameter of 0.3-1mm, and the embedding depth is 1 / 3-2 / 3 of the connector thickness, which ensures signal strength without affecting the physical properties of the sponge. An insulating coating is used to prevent conductive interference without affecting the metal detection sensitivity.
[0017] 3. The conductive yarns of this application are arranged at an angle of 45-90° with the metal markers to form a cross-induction network, which enhances the stability of signal capture.
[0018] 4. The wavy / zigzag arrangement of this application improves the coverage of the markers and avoids the detection blind spots of linear arrangement.
[0019] 5. The alternating arrangement of aluminum and copper segments in this application enables joint type identification through differentiated electromagnetic response characteristics.
[0020] In summary, this structure, while maintaining the original physical properties of the composite fabric, achieves effective monitoring of key quality control points in the automotive interior manufacturing process through a clever metal marker embedding scheme. Attached Figure Description
