Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass fiber production and manufacturing technology, specifically to a notched yarn tile and a yarn transport vehicle. Background Technology
[0002] Fiberglass yarn, due to its excellent tensile strength, insulation, and heat resistance, can be used to manufacture electronic yarn and weave electronic fabrics, commonly used in integrated circuit manufacturing, such as in the production of copper-clad laminates. With the development of automation in fiberglass manufacturing, many processes are now completed mechanically. After the fiberglass is formed into a filament cake, it is transported to a warehouse via a yarn transport vehicle, where moisture is allowed to evaporate automatically. After 8 hours, the yarn is unloaded and sorted. Because the fine yarn needs to be carefully unloaded, and the current yarn structure makes it impossible for robotic arms to unload it, unloading currently must be done manually, resulting in low efficiency.
[0003] Furthermore, with the rapid development of the information age, the requirements for electronic fiberglass cloth used as the substrate skeleton in the information field are becoming increasingly stringent. Magnetic impurities are one of the important quality indicators. If magnetic impurities are present in the electronic fiberglass cloth, it will affect the bonding with adhesives, creating bubbles and increasing the risk of board breakage. Even worse, it can affect dielectric properties and GAF performance, leading to short circuits in the circuit board. Therefore, the presence of magnetic impurities is almost unacceptable in electronic-grade fiberglass cloth. Currently, most electronic yarn transport carriages are made of hot-dip galvanized carbon steel. After prolonged use, the carriages wear down, exposing the carbon steel directly and leading to a significant amount of magnetic impurities. Summary of the Invention
[0004] This invention provides a notched yarn tile, which can overcome the problem that existing yarn transport vehicles cannot automatically unload fine yarn cakes.
[0005] The notched yarn tile of this utility model includes: a tile-shaped yarn tile body and a rear wall connected to the rear end of the yarn tile body. The yarn tile body has a yarn-picking notch that runs vertically through the middle of its upwardly arched part, allowing a robotic arm to pass through. The opening of the yarn-picking notch is located at the front end of the yarn tile body. The yarn tile also includes a reinforcing structure located on the lower side of the yarn tile body. The rear wall, the yarn tile body and the reinforcing structure are integrally formed.
[0006] Preferably, the length of the yarn-taking notch is greater than or equal to 2 / 3 of the length L of the yarn tile body, and less than or equal to 4 / 5 of the length L of the yarn tile body.
[0007] Preferably, the width of the yarn-taking notch is greater than or equal to 1 / 5 of the width W of the yarn tile body, and less than or equal to 1 / 4 of the length W of the yarn tile body.
[0008] Preferably, the reinforcing structure is arranged symmetrically about the yarn take-up notch.
[0009] Preferably, the yarn includes a resin matrix and reinforcing fibers distributed within the resin matrix.
[0010] This utility model also provides a yarn transport vehicle, including a base, a walking device installed on the lower side of the base, a support frame fixed to the upper side of the base, and a plurality of yarn tiles fixed to the support frame, wherein the yarn tiles are the yarn tiles as described above.
[0011] Preferably, both the base and the support frame include a resin matrix and reinforcing fibers located within the resin matrix.
[0012] Preferably, the base comprises two pultruded plates and a plain weave fabric located between the two pultruded plates.
[0013] Preferably, the support frame includes multiple uprights and a crossbeam connecting the multiple uprights. The support frame also includes a cross plate, which is fixedly connected to the multiple uprights. Each cross plate can fix multiple gauze tiles.
[0014] Preferably, the yarn transport cart further includes a handrail, which comprises a resin matrix and reinforcing fibers.
[0015] Compared with existing technologies, this invention has the following advantages: With the notched yarn tile of this invention, a robotic arm can pass through the notched yarn tile from bottom to top, lifting the yarn cake away from the yarn tile, thus achieving automatic yarn unloading, improving work efficiency and saving labor. The back wall, the yarn tile body, and the reinforcing structure are integrally formed, eliminating the need for installation between them. This structure ensures that even with notches, the strength of the yarn tile body is not affected. Simultaneously, this structure increases the contact area between the yarn cake and the air, creating airflow, which allows the fine yarn to dry faster. Attached Figure Description

The rear wall 14, the yarn tile body 11, and the reinforcing structures 12 and 13 are integrally formed.
[0029] Through the notched yarn tile 1 of this invention, a robotic arm can pass through the notched yarn tile 1 from bottom to top, lifting the yarn cake away from the yarn tile 1 to achieve automatic yarn unloading. This improves work efficiency and saves labor. In specific applications, multiple robotic arms can simultaneously unload yarn cakes from multiple yarn tiles on one side of the yarn transport vehicle. The rear wall 14, the yarn tile body 11, and the reinforcing structure are integrally formed, eliminating the need for installation between them. This structure ensures that the yarn tile body 11 will not be affected in terms of strength even if there is a notch. At the same time, this structure increases the contact area between the yarn cake and the air, creating airflow, which allows the fine yarn to dry faster.
[0030] Preferably, the length of the yarn-taking notch 111 is greater than or equal to 2 / 3 of the length L of the yarn body 11 and less than or equal to 4 / 5 of the length L.

The second reinforcing structure 13 connects two first reinforcing ribs located on the same side. In this embodiment, the reinforcing structure is a reinforcing rib.
[0032] In this embodiment, the yarn sheet 1 includes a resin matrix and glass fibers distributed within the resin matrix. The glass fibers are used to improve the strength of the yarn sheet 1. The yarn sheet 1 does not contain any metal components and will not introduce magnetic impurities into the yarn cake.
[0033] This utility model also provides a yarn transport vehicle, such as Figure 1 As shown, the device includes a base 2, a walking mechanism mounted on the lower side of the base 2, a support frame fixed to the upper side of the base 2, and multiple gauze tiles 1 fixed to the support frame. The gauze tiles 1 are the gauze tiles 1 as described above. The walking mechanism consists of directional casters 31 and swivel casters 32 mounted on the lower side of the base 2.
[0034] In this embodiment, both the base 2 and the support frame include a resin matrix and reinforcing fibers distributed within the resin matrix, preventing magnetic impurities from being introduced into the yarn cake. In this embodiment, the base 2 includes two pultruded plates 21 and a plain weave fabric 22 located between the two pultruded plates 21, and the support frame is bolted to the base 2.
[0035] like Figure 1 As shown, the support frame includes three uprights 4 and crossbeams 5 connecting the three uprights 4. One side of the support frame includes four horizontal plates 6, which are fixedly connected to the three uprights 4 at different heights. The connection method is bolted.
