Description

Technical Field

[0002] Additive manufacturing technology, also known as 3D printing technology, is a rapid prototyping technology that builds objects by stacking materials layer by layer based on a three-dimensional data model. With the rapid development of aerospace, automotive, medical equipment and electronics industries, traditional materials can no longer meet the needs of the current market, which has promoted the application of composite materials. Applying additive manufacturing technology to the manufacturing process of composite materials has enhanced the mechanical properties of parts.

[0027] Embodiment 1

[0028] like Figures 1 to 4 As shown, this embodiment provides an integrated additive manufacturing device for continuous carbon fiber materials, which is arranged on an additive manufacturing platform and can achieve mobile molding under the drive of the additive manufacturing platform.

[0029] In this embodiment, an integrated additive manufacturing device for continuous carbon fiber materials includes: a proximal extrusion module 1, a positioning bracket 2, a continuous carbon fiber online impregnation module 3, a resin tube 4, and a nozzle 5; wherein the proximal extrusion module 1, the positioning bracket 2 and the continuous carbon fiber online impregnation module 3 are connected in sequence from top to bottom; the resin tube 4 connects the proximal extrusion module 1 and the continuous carbon fiber online impregnation module 3 in sequence; the proximal extrusion module 1 is injected with resin material for extruding the resin material into the resin tube 4; the continuous carbon fiber online impregnation module 3 is injected with continuous carbon fiber material for online impregnation of resin material and continuous carbon fiber material to obtain a continuous carbon fiber reinforced composite material; the nozzle 5 is arranged at the lower end of the continuous carbon fiber online impregnation module 3.

[0030] Exemplarily, the positioning bracket 2 is detachably connected to the proximal extrusion module 1 and the continuous carbon fiber online impregnation module 3 .

[0031] It is worth noting that the proximal extrusion module 1 and the continuous carbon fiber online impregnation module 3 are connected as a whole through the positioning bracket 2, thereby realizing the integrated integration of the proximal extrusion module 1 and the continuous carbon fiber online impregnation module 3, realizing the additive manufacturing by proximal extrusion of resin material and continuous carbon fiber online impregnation, and being able to accurately control the extrusion amount of resin material during the movement, reducing the extrusion amount error caused by distal extrusion and improving the molding quality. In addition, the integrated integration also improves the portability of the additive manufacturing device, so that the additive manufacturing device can be conveniently transplanted to other additive manufacturing equipment as a whole.

[0032] In an optional embodiment, the proximal extrusion module 1 includes: a stepper motor 11, an extrusion transmission mechanism 12, an extrusion gear set 13 and a wire collection plate 14; wherein, the stepper motor 11, the extrusion transmission mechanism 12 and the extrusion gear set 13 are sequentially connected in transmission; the resin tube 4 is located below the extrusion gear set 13; the wire collection plate 14 is arranged on one side of the extrusion transmission mechanism 12, and the wire collection plate 14 is detachably connected to the extrusion transmission mechanism 12.

[0033] Exemplarily, the output end of the stepper motor 11 is connected to the extrusion transmission mechanism 12 through a gear transmission, and the gear of the extrusion transmission mechanism 12 is meshed with the extrusion gear set 13. The meshing transmission between the stepper motor 11 and the gear is conducive to achieving accurate control of the extrusion amount of the resin material.

[0034] Exemplarily, the wire hub 14 is threadedly connected to the extrusion transmission mechanism 12 , and the wire hub 14 is used to transfer and organize the wire harness connected to the additive manufacturing platform.

[0035] The principle is that the resin material is injected from the injection port at the upper end of the extrusion transmission mechanism 12, and under the drive of the stepper motor 11, the extrusion gear set 13 rotates to extrude the resin material into the resin tube 4 below it, and the resin tube 4 extends downward from the extrusion transmission mechanism 12 to the continuous carbon fiber online impregnation module 3, and merges with the continuous carbon fiber material in the continuous carbon fiber online impregnation module 3 to achieve online impregnation. The integrated additive manufacturing device for continuous carbon fiber material of this embodiment can be driven by the additive manufacturing platform as a whole, so that the nozzle 5 can extrude the continuous carbon fiber reinforced composite material after online impregnation in a moving state to achieve additive manufacturing molding.

[0036] In this embodiment, the continuous carbon fiber online impregnation module 3 includes: a thermally conductive aluminum block 31, a heat dissipation block 32, a throat 33, a heating rod 34, a joint 35 and a fiber tube 36; wherein the heat dissipation block 32 is detachably connected to the positioning bracket 2; a resin material channel and a continuous carbon fiber material channel are provided in the thermally conductive aluminum block 31, and the resin material channel is connected to the continuous carbon fiber material channel; the throat 33 is detachably connected to the thermally conductive aluminum block 31; the resin tube 4 passes through the heat dissipation block 32 and is coaxially connected to the throat 33, and the throat 33 is connected to the resin material channel; the heating rod 34 is arranged on one side of the thermally conductive aluminum block 31; an inclined surface is provided on the other side of the thermally conductive aluminum block 31, and the joint 35 is detachably arranged on the inclined surface, the joint 35 is connected to the continuous carbon fiber material channel, and the fiber tube 36 is sleeved in the joint 35; the nozzle 5 is arranged at the lower end of the thermally conductive aluminum block 31, and the nozzle 5 is detachably connected to the thermally conductive aluminum block 31.

[0037] Exemplarily, the inclined surface of the heat-conducting aluminum block 31 is set to a 45° inclined surface, which is conducive to the injection of continuous carbon fiber material.

[0038] Exemplarily, the throat 33 is connected to the upper end of the heat-conducting aluminum block 31 by threads, the nozzle 5 is connected to the lower end of the heat-conducting aluminum block 31 by threads, the resin tube 4 is sleeved in the throat 33, and the joint 35 is connected to the inclined side of the heat-conducting aluminum block 31 by threads. The threaded connection is easy to disassemble, and when the plug and wire blocking phenomenon occurs, it can be quickly disassembled, so that the broken wires of the resin material and the continuous carbon fiber material can be cleaned under high temperature. In addition, the threaded connection can also effectively prevent the resin material from overflowing.

[0039] For example, both the resin tube 4 and the fiber tube 36 may be Teflon tubes, which have the characteristics of high temperature resistance and good heat insulation.

[0040] It is worth noting that the resin tube 4, the throat 33, the resin material channel and the nozzle 5 are coaxially arranged in sequence, and the central axis of the resin tube 4 coincides with the longitudinal axis of the extrusion transmission mechanism 12, so as to facilitate more precise extrusion of the resin material. After the resin material and the continuous carbon fiber material are merged, they are extruded together from the center position of the nozzle 5, which improves the wrapping effect of the resin material on the continuous carbon fiber material and is beneficial to improving the molding quality.

[0041] Furthermore, the resin tube 4 passes through the longitudinal axis of the heat dissipation block 32, and the heat dissipation block 32 ensures that the resin material has a lower temperature during the process of being extruded into the resin material channel, so that the resin material can be effectively driven by the extrusion thrust of the extrusion gear group 13, smoothly move into the resin material channel, and finally be extruded from the nozzle 5.

[0042] In an optional embodiment, a thermistor 37 is disposed on one side of the heat-conducting aluminum block 31 , and the thermistor 37 is used to detect the temperature of the heat-conducting aluminum block 31 .

[0043] Exemplarily, the thermistor 37 is arranged near the heating rod 34, and the thermistor 37 is used to detect the temperature of the heat-conductive aluminum block 31 to obtain temperature information. The heating rod 34 and the thermistor 37 are both connected to the external control module of the additive manufacturing platform. After the external control module obtains the temperature information, it controls the heating power of the heating rod 34 in real time according to the temperature information, thereby ensuring the temperature stability during the online dipping process.

[0044] Furthermore, a temperature measuring hole is provided on one side of the heat-conducting aluminum block 31 , and the thermistor 37 is disposed in the temperature measuring hole and is detachably connected via a combination screw.

[0045] It should be noted that the continuous carbon fiber online impregnation module 3 of the present embodiment is capable of realizing online impregnation, wherein the heating rod 34 is used for heating, the heat-conducting aluminum block 31 is used for heat conduction, and the thermistor 37 is used to detect the temperature of the heat-conducting aluminum block 31; and the processing of temperature information and the control of the heating power of the heating rod 34 are not the contents of the integrated additive manufacturing device for continuous carbon fiber materials of the present embodiment, and are not restricted in the present embodiment.

[0046] During the molding process, warping of the first layer or uneven amount of resin material may cause an uneven molding surface. In order to ensure the final molding quality, height compensation is required. In view of this, the integrated additive manufacturing device for continuous carbon fiber materials in this embodiment also includes: a non-contact height sensor 6.

[0047] Specifically, the non-contact height sensor 6 is arranged on one side of the positioning bracket 2, and is used to detect the height of the nozzle 5 and the height of the continuous carbon fiber reinforced composite material layer extruded by the nozzle 5 to obtain height information respectively, and the additive manufacturing platform then adjusts the height of the additive manufacturing device according to the height information.

[0048] Exemplarily, the non-contact height sensor 6 is detachably connected to the positioning bracket 2 .

[0049] Exemplarily, the non-contact height sensor 6 may be a leveling sensor.

[0050] The principle is that the nozzle 5 extrude continuous carbon fiber reinforced composite material on the plane of the additive manufacturing platform, and gradually forms a layer of continuous carbon fiber reinforced composite material, which is a molding surface. If the nozzle 5 is lifted to continue molding when the molding surface is uneven, the molding surface or the newly solidified continuous carbon fiber reinforced composite material will cause the molding surface or the newly solidified continuous carbon fiber reinforced composite material to squeeze the nozzle 5, which will cause wire breakage or wire blocking. At this time, the non-contact height sensor 6 detects the height of the nozzle 5 and the height of the molding surface in real time to obtain height information respectively. The additive manufacturing platform adjusts the distance between the nozzle 5 and the molding plane or the distance between the nozzle 5 and the plane of the additive manufacturing platform according to the height information. After adjustment, molding on the previous molding surface can effectively avoid the problem of continuous carbon fiber reinforced composite material extrusion nozzle 5. In addition, according to the height information, the stepper motor 11 can also be controlled to reverse, and the resin material can be withdrawn through the extrusion gear set 13 to reduce the proportion of the resin material and achieve precise control of the extrusion amount of the resin material.

[0051] Furthermore, in order to ensure the accuracy of the height information, the bottom surface of the non-contact height sensor 6 may be arranged to be parallel to the bottom surface of the nozzle 5 .

[0052] Furthermore, the bottom surface of the non-contact height sensor 6 and the bottom surface of the nozzle 5 can be arranged to be parallel to the plane of the additive manufacturing platform.

[0053] In an optional embodiment, the integrated additive manufacturing device for continuous carbon fiber materials further includes: a heat dissipation fan 7; the heat dissipation fan 7 is located below the proximal extrusion module 1 and is detachably connected to the positioning bracket 2. The heat dissipation fan 7 and the heat dissipation block 32 work together to dissipate heat for the additive manufacturing device, and the heat dissipation fan 7 also serves to cool the molded parts.

[0054] The working principle of the integrated additive manufacturing device for continuous carbon fiber materials of this embodiment is that the bottom surface height of the nozzle 5 is first measured by the non-contact height sensor 6, and the additive manufacturing platform is leveled; the resin material is injected from the injection port at the upper end of the extrusion transmission mechanism 12, and the continuous carbon fiber material is injected from the fiber tube 36; driven by the stepper motor 11, the extrusion gear set 13 extrude the resin material into the resin tube 4 below it, and enter the resin material channel through the throat 33. The heat-conducting aluminum block 31 is heated by the heating rod 34, and the resin material and the continuous carbon fiber material inside the heat-conducting aluminum block 31 are fully fused and then extruded from the nozzle 5. During the molding process, the non-contact height sensor 6 obtains the height information in real time and feeds it back to the additive manufacturing platform, and the additive manufacturing platform then adjusts the height of the nozzle 5 in real time according to the height information, and controls the stepper motor 11 to reverse to realize the withdrawal of the resin material. At the same time, the thermistor 37 obtains the temperature information in real time, and the additive manufacturing platform controls the heating power of the heating rod 34 according to the temperature information, and dissipates and cools the molded parts through the cooling fan 7.

[0055] The integrated additive manufacturing device for continuous carbon fiber materials of the present invention integrates a proximal extrusion module and a continuous carbon fiber online impregnation module into one, thereby reducing the extrusion amount deviation caused by distal extrusion, achieving accurate control of the extrusion amount of the resin material, and improving the molding quality; at the same time, it also improves the portability, so that the proximal extrusion module and the continuous carbon fiber online impregnation module can be transplanted to other additive manufacturing equipment in an integrated manner.

[0056] The present invention uses a non-contact height sensor to feedback the height information of the nozzle and the continuous carbon fiber reinforced composite material layer, so that the additive manufacturing platform can make real-time adjustments and compensations according to the height information, thereby solving the problems of fiber blockage and breakage and uneven molding surface caused by height problems.

[0057] This embodiment also provides an additive manufacturing device, including: an additive manufacturing platform, and an integrated additive manufacturing device for continuous carbon fiber materials arranged on the additive manufacturing platform.

[0058] It can be understood that the integrated additive manufacturing device for continuous carbon fiber materials of this embodiment can be used as an integral module and transplanted to the existing additive manufacturing equipment; it can also be integrally embedded in the equipment during design and development.
