Description

Technical Field

[0001] This invention relates to the field of glass fiber prepreg processing and molding equipment, and in particular to a malleable, high-temperature resistant glass fiber prepreg processing and molding equipment and process. Background Technology

[0002] Fiberglass prepreg is a sheet-like semi-finished product made by impregnating fiberglass cloth with epoxy resin and then baking it to achieve the semi-cured B stage. It is a core material for manufacturing multilayer printed circuit boards and high-end composite material components. Among them, fiberglass grid cloth, as the mechanical reinforcing skeleton of fiberglass prepreg, directly determines the tensile strength, anti-warping performance, and dimensional stability of the prepreg by the structural stability and molding precision of its grid nodes. It is a core factor affecting the service life and reliability of the final product.

[0003] Chinese patent CN201910362162.2 discloses a fiberglass grid weaving system, which solves the material supply bottleneck in wide-width production by using a multi-channel transverse rib supply component, and uses a gear and rack component to drive all weaving units to rotate synchronously, interweaving the transverse and longitudinal ribs together, and finally outputting the finished fiberglass grid smoothly by a special "U-shaped" frame traction device.

[0004] However, while this technical solution achieves automated production of wide-width grids through multi-tube transverse rib supply and synchronous weaving components, significantly improving weaving efficiency, it still has at least two shortcomings: 1. This type of weaving equipment only focuses on the interlacing and forming process of warp and weft yarns, and the resulting grid nodes are mainly fixed by the torsional friction between the yarns. In practical applications, especially in the fields of composite material reinforcement or building reinforcement under complex stresses, these one-time formed nodes are prone to slippage and loosening under long-term loads or alternating stresses, leading to a decrease in the overall stability of the grid structure and affecting the product's service life and reliability. 2. The system only focuses on the execution of the weaving action itself and does not have any detection unit for real-time sensing of the grid node forming quality. During long-term continuous operation, the grid nodes may exhibit uneven tension, local loosening, or even weaving failure. Existing technologies lack the ability to monitor this key quality parameter online, making it impossible to detect these node defects in a timely manner, let alone have a mechanism for automatically identifying and remedying failed nodes. This blindly implemented work model often relies on manual, timed shutdowns for spot checks to indirectly control quality. This not only affects the continuity and efficiency of production, but also makes the long-term reliability of the product highly dependent on the stability of the equipment's initial state and the experience level of the operators, making it difficult to fundamentally guarantee the forming quality of each grid node.

[0005] Therefore, in the actual use of existing fiberglass grid weaving systems, there are common problems such as the nodes being prone to slippage and loosening under long-term loads or alternating stresses, as well as the inability to detect node defects in a timely manner, and the lack of a mechanism for automatically identifying and remedying failed nodes, such as rewinding and reinforcing them. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a malleable high-temperature resistant glass fiber prepreg processing equipment and process. Through a complete process design that includes secondary reinforcement of nodes, micro-melting curing, cooling and leveling, online detection, and automatic defect repair, this invention fundamentally solves the industry pain points of easy slippage and loosening of glass fiber grating nodes, lack of online quality control, insufficient molding accuracy, and inability to automatically repair defects. This significantly improves the structural stability, molding accuracy, and production continuity of glass fiber grating, ultimately ensuring the high-temperature resistance and mechanical properties of the glass fiber prepreg.

The micro-fusion assembly 3 includes: The third lead screw slide assembly 31 is located on the side wall of the braiding machine, and two sets are provided on the left and right sides respectively. The third fixing bracket 32, the first fixing bracket 112 is mounted on the third lead screw slide assembly 31, and the heating element 33 is a pulse ceramic heating tube; Heating element 33, which is mounted on the third fixed frame 32 and is evenly distributed in several groups corresponding to the nodes.

[0031] It should be noted that in this embodiment, when the fiberglass grid cloth travels to the micro-melting component 3 station, the third screw slide assembly 31 drives the upper and lower sets of heating elements 33 to move towards each other to 2mm above the node. The heating elements 33 instantly heat up to 350°C, causing the excess fiberglass wires after winding to melt and at the same time causing the ends of the fiberglass wires to micro-melt and adhere to the node body, preventing the fiberglass wires from springing back and loosening, and further solidifying the node structure.

[0032] As an improvement, a cooling and leveling component 4 is also included, located behind the micro-melting component 3, for cooling and leveling the glass fiber after die-casting and melting, the cooling and leveling component 4 comprising... The fourth lead screw slide assembly 41 is located on the side wall of the braiding machine, and two sets are provided on the left and right sides respectively. The fourth fixing frame 42 is mounted on the fourth lead screw slide assembly 41, and the fourth fixing frame 42 has a U-shaped first cooling channel 421 inside; Cooling plate 43 is mounted on fourth fixed frame 42 and several groups are evenly distributed corresponding to nodes. The cooling plate 43 has a second cooling channel 431 inside, which is connected to the first cooling channel 421. The second cooling channel 431 is a multi-channel parallel serpentine flow channel, which is composed of several equidistant parallel straight flow channels and U-shaped bends at both ends connected in series. The whole is arranged in a rectangular shape, which can ensure the temperature uniformity of the working surface of the cooling plate 43 and control the temperature difference within ±1℃.

[0033] It should be noted that the coolant enters from the inlet end of the first cooling channel 421, flows through the second cooling channel 431 of each group of cooling plates 43 to cool the cooling plates 43, and then flows out from the outlet end to complete the cooling of each group of cooling plates 43.

[0034] It should be noted that when the fiberglass grid cloth moves to the cooling and flattening assembly 4, the fourth screw slide assembly 41 drives the cooling plate 43 located on the fourth fixed frame 42 to move up and down towards the node. Furthermore, the micro-melted node is merged and die-cast, so that the fiberglass wire wrapped around the node is cooled and die-cast flat.

[0035] Work steps Step 1: Node reinforcement. The fiberglass grid cloth stops moving when it reaches the station of the fixing component. Further, the tensioning groups located on the upper and lower sides of the fiberglass grid cloth, driven by the first driving component, move towards each other and tighten the fiberglass grid cloth, fixing it and keeping it taut. After the fixing device keeps the fiberglass grid cloth taut, a winding device moves synchronously at an inclined angle to the node of the fiberglass grid cloth to perform winding and binding, fixing the node securely. After completing the winding, it returns to the initial position. Further, another winding machine repeats the above actions, completing secondary binding at another inclined position corresponding to the first winding device, thus reinforcing the fiberglass grid cloth node a second time.

[0036] Step 2, Micro-melting and curing: When the fiberglass grid cloth moves to the micro-melting component, the third screw slide assembly drives the heating element located on the third fixed frame to move up and down towards the node. The heating element heats up the fiberglass wire connected to the winding device, causing it to melt and its surface to micro-melt under the action of heating, thus stabilizing the fiberglass wire wound around the node.

[0037] Step 3: Cooling and leveling. When the fiberglass grid cloth moves to the cooling and leveling component, the fourth screw slide component drives the cooling plate on the fourth fixed frame to move up and down towards the node. Further, the micro-melted node is merged and die-cast, so that the fiberglass wire wrapped around the node is cooled and die-cast flat.

[0038] Step 4: Detection and Remediation. When the fiberglass grid cloth moves to the identification component, the fifth lead screw slide assembly of one set of identification components drives the detection axial node displacement located on the fifth fixed frame until the fiberglass wire is stuck in the semi-circular groove. Further displacement continues until it passes the node position. The detection device observes whether the node is separated. Further, another set of identification components repeats the above actions to detect whether the node is fixed. When the fiberglass grid cloth moves to the remediation component, the second fixing component fixes and tightens the fiberglass wire. Further, the cutting component cuts and peels the fiberglass wire at the node. Further still, the vibrating blower component vibrates and blows the fiberglass wire wrapped around the node into the waste bin below, completing the cleaning of the defective fiberglass wire at the node. Further still, the second winding component completes the secondary fixation of the node.

[0039] Step 5: Winding. After the fiberglass grid cloth has completed the entire process, the tension is adjusted by the tension control system and then continuously wound up under constant tension by the winding device. The finished fiberglass grid cloth after winding is used for subsequent epoxy resin impregnation and baking of the semi-cured board.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
