Description

TECHNICAL FIELD

[0001] The present application relates to a fiber resin infiltration method for composite fiber winding forming, and particularly relates to a composite carbon fiber resin infiltration technology field for building structures. BACKGROUND

[0002] Industrial robot arms are applied in batch production fields such as automobile factory body assembly, and mainly engage in a large number of repetitive work. With the development of computers and artificial intelligence, the robot work originally required by professional engineers programming can now generate code directly through visual programming methods, so that the robot can be applied to the field of generating building components with higher customization.

[0003] Compared with traditional building structure materials, due to the flexibility and lightweight characteristics of composite carbon fiber structures, composite carbon fiber materials become the preferred materials for digital construction and robot construction of building structure components. The material characteristics make it beneficial to rapid disassembly and reinstallation. At the same time, the design and manufacturing of such composite carbon fiber structures are more flexible than the traditional construction process of buildings.

[0004] However, there are difficulties in the application of existing composite carbon fiber materials in the building field. The application is often a large-size composite fiber winding forming, and there is a speed requirement when applied online. The conventional infiltration method in other fields cannot guarantee the quality requirements of fiber resin infiltration during the operation of the building robot. Therefore, a fiber resin infiltration method and system for large-size composite fiber winding forming for building field application are needed to meet the high extrusion quantity (1 m / s) and high infiltration degree requirements. SUMMARY

[0005] The purpose of the present application is to solve the problems existing in the prior art, and to provide a composite fiber resin infiltration method and system based on mechanical arm online construction.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] A composite fiber resin infiltration method, comprising the following steps:

[0008] 1) The mechanical arm for construction provides a pulling force to the fiber yarn, takes the material from the fiber yarn tray, and then introduces the continuous fiber yarn into the fiber infiltration table in parallel. After the fiber yarn is infiltrated with an appropriate amount of resin in the fiber infiltration table, the fiber yarn is bundled and used for construction;

[0009] 2) The fiber infiltration station comprises adjacent resin infiltration area and resin recovery area. An open-top resin storage tank is arranged in the resin infiltration area, and a resin roller is arranged on the storage tank. The lower part of the resin roller is always immersed in resin. A quantitative scraper is arranged on one side of the resin roller to control the thickness of the resin on the surface of the resin roller. An open-top resin recovery tank is arranged in the resin recovery area, and a fiber tension floating stabilizer and a wet fiber guide are arranged above the recovery tank.

[0010] 3) After the parallel fiber filaments enter the resin infiltration area, the upper surface of the resin roller is contacted and infiltrated with resin, and the resin roller is driven to rotate. The fiber filaments after resin infiltration pass through the fiber tension floating stabilizer to maintain stable fiber tension, then pass through the wet fiber guide, and finally pass through the bundle width to determine the diameter of the composite fiber resin material entering the mechanical arm end.

[0011] In order to parallelly introduce the continuous fiber filaments into the resin infiltration area, a dry fiber guide is arranged at the entrance of the resin infiltration area, and the continuous parallel fiber filaments enter from below the dry fiber guide. The dry fiber guide can be a driven dry roller with smooth surface, and the length is consistent with that of the resin roller, so as to maintain the parallel movement of the fiber filaments to the upper surface of the resin roller.

[0012] In order to further control the resin infiltration amount of the fiber filaments, a first fiber guide rod is arranged in front of the quantitative scraper, and a second fiber guide rod is arranged on the other side of the resin roller. The parallel fiber filaments coming out from the lower surface of the dry fiber guide pass around the lower surface of the first fiber guide rod, then contact the upper surface of the resin roller, and then pass around the lower surface of the second fiber guide rod and enter the fiber tension floating stabilizer. The first fiber guide rod and the second fiber guide rod are movably connected with the fiber infiltration station, and the distance between the resin roller and the first fiber guide rod and the second fiber guide rod is adjusted to control the resin infiltration area and the contact pressure of the parallel fiber filaments on the surface of the resin roller. The first fiber guide rod and the second fiber guide rod are smooth in surface to avoid damage to the fiber. At the same time, the pressure applied by the second fiber guide rod to the fiber filaments extrudes the excess resin on the fiber. The first fiber guide rod and the second fiber guide rod are driven guide rods.

[0013] The resin roller needs to be smooth in surface, and is movably or fixedly connected with the fiber infiltration station, and is preferably movably connected. For example, the resin roller is fixed on the fiber infiltration station by a quick-release fixing part. When the parallel fiber filaments under tension drive the resin roller to rotate, the lower surface of the resin roller adheres to the prepared epoxy resin in the resin storage tank, and then rotates to contact the fiber filaments above.

[0014] The quantitative scraper can be a combination of a stainless steel sheet and a moving slider, which is arranged on the fiber infiltration table and used to fine-tune the amount of resin adsorbed by the fiber when the fiber is attached to the resin roller. By determining the gap distance between the quantitative scraper and the surface of the resin roller, a resin film with a set thickness can be formed on the resin roller. The fiber with tension moves on the resin adhesion area of the resin roller, and the fiber is compacted with the same proportion of resin material. At the same time, the pulling speed and the fiber tension also affect the rolling speed of the resin roller and the contact force between the fiber and the surface of the roller, forming different resin thicknesses of the roller (different rotation speeds, different dropping amounts), and the contact area between the fiber and the roller, thereby changing the amount of resin adhered to the fiber, and achieving uniform resin infiltration of the fiber at different speeds of the fiber material line speed.

[0015] In order to maintain the continuous tension of the fiber material during the uneven speed movement of the mechanical arm in the construction process, a fiber tension floating stabilizer is arranged to fine-tune the fiber tension at the resin roller discharge end.

[0016] The fiber tension floating stabilizer provided by the patent comprises a fixed seat, a supporting rod, an adjusting nut, a compression spring, a cross beam, a sliding block and a fiber conduit. The compression spring is sleeved on the supporting rod. The sliding block is arranged at the middle part of the compression spring. The adjusting nut is arranged at the top of the compression spring. The supporting rod is fixed to the two sides of the infiltration table through the fixed seat. The cross beam is fixedly connected with the sliding block at both ends. The fiber conduit is arranged on the cross beam. The up-and-down position of the sliding block is adjusted by the compression spring through the adjusting nut, thereby controlling the local fiber tension, and avoiding the fiber tension on the surface of the resin roller exceeding the normal range when the pulling speed is too fast, which affects the infiltration degree. The number of fiber conduits is determined according to the number of parallel fiber filaments, and is more than or equal to the number of running cellulose. The material of the fiber conduit is preferably titanium oxide ceramic.

[0017] The bundled fiber material after passing through the fiber tension floating stabilizer is guided by the bundle width guide to determine the final diameter of the fiber material. The bundle width guide provided by the patent is a titanium oxide ceramic roller and its supporting rod. The roller has a V-shaped notch, and the width of the slope bottom of the V-shaped notch is used to determine the width of the bundled fiber material. Different rollers can be replaced according to needs to adjust the final width of the bundled fiber within a certain range.

[0018] In order to further control the tension of the moving fiber, a counterweight is arranged on the bundle width guide to stretch the fiber to a set tension level. During on-site operation, a slide rail can be arranged on the support frame supporting the bundle width guide, a sliding table is arranged on the slide rail, the sliding table is connected with the supporting rod of the bundle width guide, and the counterweight for adjustment is arranged on the sliding table, thereby controlling the tension of the moving fiber. The counterweight is a weight block with different standards.

[0019] Another part of the tension comes from the holding force of the robot tool connected to the discharge end.

[0020] A composite fiber resin infiltration system, comprising a fiber infiltration platform and a composite fiber mechanism, the fiber infiltration platform comprising adjacent resin infiltration area and resin recovery area, an upper open resin storage tank is arranged in the resin infiltration area, and a resin roller is arranged on the storage tank; a quantitative scraper is arranged on one side of the resin roller for controlling the resin thickness on the surface of the resin roller; an upper open resin recovery tank is arranged in the resin recovery area, and a fiber tension floating stabilizer and a wet fiber guide are arranged above the recovery tank; the composite fiber mechanism comprises a workbench, a bundle width guide and a counterweight, the bundle width guide comprises rollers and support rods, and the two ends of the support rods are arranged on the side walls of the workbench; a fiber guide roller is arranged at the top of the workbench, slide rails are arranged on both sides of the workbench, and slide tables are arranged on the slide rails, and different counterweights are arranged on the slide tables according to needs.

[0021] Further, a dry fiber guide is arranged at the entrance of the resin infiltration area, and the continuous parallel fiber filaments enter from below the dry fiber guide. The dry fiber guide can be a smooth driven dry roller with a length consistent with that of the resin roller, so as to maintain the parallel movement of the fiber filaments to the upper surface of the resin roller.

[0022] Further, a first fiber guide rod is arranged in front of the quantitative scraper, and a second fiber guide rod is arranged on the other side of the resin roller, the first fiber guide rod and the second fiber guide rod are movably connected with the fiber infiltration platform, and the resin infiltration area and the contact pressure of the parallel fiber filaments on the surface of the resin roller are controlled by moving the distance between the first fiber guide rod and the second fiber guide rod and the resin roller. The first fiber guide rod and the second fiber guide rod are smooth in surface to avoid damage to the fibers. The first fiber guide rod and the second fiber guide rod are driven guide rods.

[0023] Further, the resin roller needs to be smooth in surface, and can be movably connected or fixedly connected with the fiber infiltration platform, and the movable connection is preferred. For example, the resin roller is fixed on the fiber infiltration platform by a quick-release fixing part.

[0024] Further, the quantitative scraper is a combination of a stainless steel sheet and a moving slider, which is arranged on the fiber infiltration platform and used for fine adjustment of the resin amount adsorbed by the fiber filaments when the fiber filaments are attached to the resin roller. By determining the gap distance between the quantitative scraper and the surface of the resin roller, a resin film with a set thickness can be formed on the resin roller, the resin adhered area of the fiber moving with tension on the resin roller is compacted, and a resin material with the same proportional thickness is attached.
