Description

Technical Field

[0001] The utility model relates to the field of composite material manufacturing, and specifically relates to a modular continuous fiber composite material braiding and forming device. Background Technique

[0002] Continuous fiber composite materials are widely used in multiple fields due to their excellent properties to reduce weight and improve fuel efficiency and performance. In addition, continuous fiber composite materials are also widely used in fields such as sporting goods, medical devices, and construction. With the continuous progress of technology and the reduction of costs, their application fields are expected to be further expanded.

[0003] The utility model patent with the patent announcement number CN210945965U discloses a fiber composite material connection and braiding device, including a frame. A braiding machine is placed on the top of the frame. One side of the braiding machine is provided with a support rod. The bottom end of the support rod penetrates through the frame and extends to the other side of the frame. The support rod is movably connected to the frame through a bearing sleeve. The top of the support rod is fixedly connected with a support plate. Both sides of the support plate are fixedly connected with connecting pipes. One end of the connecting pipe far away from the support plate is fixedly connected with an air inlet. A first fan is fixedly connected to the top of the connecting pipe near the air inlet. A second fan is connected inside the connecting pipe near the support plate. A storage box is arranged on the outer surface of the support rod and below the connecting pipe.

[0004] In the above utility model patent, when connecting and braiding fiber composite materials, it can remove fibers in the air, improve the safety of the processing environment, and reduce the harm to the physical health of processing personnel. Moreover, two sets of connecting pipes for removing fibers are adopted and used alternately, which is convenient for relevant personnel to clean the storage box and enables the operation of removing fibers to be carried out continuously. However, all the device parts of this braiding equipment are fixedly installed, which is not convenient for flexible adjustment of the equipment and is not conducive to the disassembly and maintenance of the equipment by the staff. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a modular continuous fiber composite material braiding and forming device, which solves the problems put forward in the above background technique.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A modular continuous fiber composite material weaving and forming device, including a base, a slide rail and a main switch. The slide rail is fixedly installed on the top of the base. The surface of the slide rail is provided with screw holes, and fixing screws are installed at the screw holes. A robotic arm is arranged inside the slide rail. The robotic arm is fixed to the inner wall of the slide rail through the fixing screws. A connecting wire is fixedly installed on the surface of the robotic arm, and the connecting wire is electrically connected to the robotic arm. A socket is provided on the surface of the base. A fixing ring is rotatably installed at the top of the robotic arm. An inner ring is rotatably installed on the surface of the fixing ring. A connecting seat is rotatably installed on the surface of the inner ring. A rotor is fixedly installed on the surface of the connecting seat. One end of the rotor away from the connecting seat is fixedly installed with a discharge port. A bracket is fixedly installed on the top of the base. The bracket is provided with a hydraulic rod, and the hydraulic rod is connected to the power supply. A clamping plate is rotatably installed at the free end of the hydraulic rod. A clamping plate is sleeved inside the clamping plate. A weaving frame is fixedly installed on the surface of the clamping plate. Hooks are fixedly installed on the surface of the weaving frame. The fibers released from the discharge port are woven after two rounds of winding and then undergo the final step of weaving and forming on the surface of the weaving frame.

[0007] Preferably, there are two sets of robotic arms symmetrically placed on the top of the base, and both sets of robotic arms are provided with discharge mechanisms.

[0008] Preferably, a clamping strip is slidably installed on the surface of the clamping plate. The top of the clamping strip is set as an inclined surface. A first spring is arranged between the clamping strip and the clamping plate. After inserting the clamping plate into the clamping plate, the clamping strip will clamp the clamping plate tightly. Pulling out the clamping strip can remove the clamping plate, which is convenient for installation and disassembly.

[0009] Preferably, a protective plate is fixedly installed at the free end of the hydraulic rod. A rotating plate is rotatably installed on the surface of the clamping plate. A push rod is sleeved in the protective plate. An elastic member is arranged between the push rod and the protective plate. The part of the push rod close to the rotating plate is set as an inclined surface. A spring knife is slidably installed inside the protective plate. A second spring is arranged between the spring knife and the protective plate. A limiting plate is slidably installed on the surface of the protective plate. The limiting plate penetrates through the spring knife and clamps the spring knife tightly. A baffle is fixedly installed on the surface of the push rod. The top of the baffle contacts the bottom of the limiting plate. A slot is opened on the surface of the baffle. A push-pull rod is fixedly installed on the surface of the push rod. An air cylinder is fixedly installed on the surface of the protective plate. One end of the push-pull rod close to the air cylinder penetrates through the air cylinder and is fixedly installed with a piston plate. An opening is opened on the surface of the piston plate. A movable block is slidably installed at the opening. A third spring is arranged between the movable block and the piston plate. The spring knife pops out under the elastic force of the second spring to cut off the fibers at the knotted part, preventing the continuous release of fibers at the discharge port, causing more fiber knots and resulting in waste.

[0010] Preferably, a torsion spring is provided between the rotating plate and the clamping plate. There are two groups of elastic knives symmetrically placed at both ends of the inner wall of the guard plate, and the two groups of elastic knives are fixedly connected by a connecting strip. A secondary switch is provided on the inner wall of the guard plate, and the secondary switch is electrically connected to the power supply. The shape of the groove on the surface of the baffle is consistent with the cross-section of the limiting plate, and the area is slightly larger than the cross-section of the limiting plate. A fourth spring is provided between the limiting plate and the guard plate. When the elastic knife pops out, it triggers the secondary switch to cut off the power supply and protect the device.

[0011] Preferably, the movable block can only move in a direction away from the push rod. There is a small gap between the movable block and the piston plate. The push rod is U-shaped, and the length of the end close to the air cylinder is greater than the length of the air cylinder. When a knot occurs during the weaving process, the push rod will keep moving until the piston plate is pushed out of the air cylinder.

[0012] The utility model provides a modular continuous fiber composite material weaving and forming device, which has the following beneficial effects:

[0013] (1) For the modular continuous fiber composite material weaving and forming device, the mechanical arm and the weaving frame are both installed in a modular mode. This design facilitates the disassembly and installation of the device. At the same time, the installation position of the device can be adjusted according to the model size of the product, which is suitable for various production conditions. When the device has problems, it is also convenient for the staff to check and repair. The fibers are wound and woven to different degrees through the rotation of the connecting seat and the inner ring, improving the strength of the fibers.

[0014] (2) For the modular continuous fiber composite material weaving and forming device, when the fibers are accidentally knotted during the weaving process, the clamping plate no longer drives the rotating plate to squeeze the push rod. After the push rod resets, it pushes the piston plate out of the air cylinder. Then, the quickly moving push rod drives the baffle to move, aligning the groove on the surface of the baffle with the limiting plate. After the limiting plate pops out, the limit on the elastic knife is released, and the elastic knife pops out to cut off the knotted part of the fibers, avoiding more fiber knotting and waste caused by the fiber still being released from the discharge port after the fibers are knotted. At the same time, when the elastic knife pops out, it contacts the secondary switch to cut off the power supply and protect the device. Description of the Drawings

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 6, the present utility model provides a technical solution: a modular continuous fiber composite material weaving and forming device, including a base 1, a slide rail 2 and a main switch 8. The slide rail 2 is fixedly installed on the top of the base 1. A number of screw holes are provided on the surface of the slide rail 2, and the screw holes are arranged in sequence along the slide rail 2. And fixing screws 5 are installed at the screw holes. A robotic arm 4 is arranged inside the slide rail 2. The robotic arm 4 is fixed to the inner wall of the slide rail 2 by the fixing screws 5. The installation position of the robotic arm 4 can be adjusted according to different production situations and product sizes. Select different screw holes on the surface of the slide rail 3 to install the robotic arm 4. A connecting wire 6 is fixedly installed on the surface of the robotic arm 4, and the connecting wire 6 is electrically connected to the robotic arm 4. A socket 7 is provided on the surface of the base 1. When the robotic arm 4 is not needed, the connecting wire 6 can be pulled out to avoid line loss. A fixing ring 10 is rotatably installed at the top of the robotic arm 4. The fixing ring 10 is connected to the top of the robotic arm 4 through a hinge part, so that the fixing ring 10 can rotate on the top of the robotic arm 4 to adjust the production angle, and the hinge part can be removed after the production is completed, so that the fixing ring 10 is separated from the robotic arm 4, which is convenient for the staff to repair the fixing ring 10 and related devices. An inner ring 11 is rotatably installed on the surface of the fixing ring 10. When the friction between the inner ring 11 and the fixing ring 10 increases and the normal rotation of the inner ring 11 cannot be guaranteed, the inner ring 11 is disassembled to check the internal situation. The staff can polish and maintain the surface of the disassembled inner ring 11. After the maintenance is completed, it can be reinstalled on the surface of the fixing ring 10 for use. A connecting seat 12 is rotatably installed on the surface of the inner ring 11. A rotor 13 is fixedly installed on the surface of the connecting seat 12. An outlet 14 is fixedly installed at one end of the rotor 13 away from the connecting seat 12. When necessary, the connecting seat 12 and the rotor 13 can be disassembled together to facilitate the staff to check the smoothness of the outlet 14. After the inspection is completed, the connecting seat 12 can be reinstalled on the surface of the inner ring 11. A support 3 is fixedly installed on the top of the base 1. A hydraulic rod 9 is provided on the support 3. The hydraulic rod 9 is connected to the power supply. A clamping plate 15 is rotatably installed at the free end of the hydraulic rod 9. A clamping plate 16 is sleeved inside the clamping plate 15. A weaving frame 17 is fixedly installed on the surface of the clamping plate 16. Before use, the clamping plate 16 is inserted into the clamping plate 15 to achieve the effect of stabilizing the weaving frame 17. Hooks are fixedly installed on the surface of the weaving frame 17. The fibers released from the outlet 14 are woven after two rounds of winding and then undergo the final step of weaving and forming on the surface of the weaving frame 17.

[0024] There are two sets of robotic arms 4 and they are symmetrically placed on the top of the base 1. Both sets of robotic arms 4 are provided with discharging mechanisms.

[0025] A clamping strip 18 is slidably mounted on the surface of the clamping plate 15. The top of the clamping strip 18 is provided with an inclined surface. A first spring is arranged between the clamping strip 18 and the clamping plate 15. After the clamping plate 16 is inserted into the clamping plate 15, the clamping strip 18 will clamp the clamping plate 16 tightly. When the weaving work is completed, it is necessary to replace the weaving frame 17 wound with fibers. The clamping strip 18 is pulled out. The clamping strip 18 no longer clamps the clamping plate 16 tightly, and then the clamping plate 16 can be taken out and the weaving frame 17 can be taken out. Then a new weaving frame 17 is installed to continue the weaving work, which is convenient for the staff to disassemble and replace the weaving frame after the weaving is completed.

[0026] A protective plate 20 is fixedly mounted at the free end of the hydraulic rod 9. A rotating plate 19 is rotatably mounted on the surface of the clamping plate 15. A push rod 21 is sleeved on the protective plate 20. An elastic member is arranged between the push rod 21 and the protective plate 20. The push rod 21 is provided with an inclined surface near the rotating plate 19. A spring knife 23 is slidably mounted on the inner wall of the protective plate 20. A second spring is arranged between the spring knife 23 and the protective plate 20. A limiting plate 24 is slidably mounted on the surface of the protective plate 20. The limiting plate 24 penetrates through the spring knife 23 and clamps the spring knife 23 tightly. A baffle 25 is fixedly mounted on the surface of the push rod 21. The top of the baffle 25 contacts the bottom of the limiting plate 24. A slot is opened on the surface of the baffle 25. A push-pull rod 27 is fixedly mounted on the surface of the push rod 21. An air cylinder 28 is fixedly mounted on the surface of the protective plate 20. One end of the push-pull rod 27 close to the air cylinder 28 penetrates through the air cylinder 28 and is fixedly mounted with a piston plate 29. An opening is opened on the surface of the piston plate 29. A movable block 30 is slidably mounted at the opening. A third spring is arranged between the movable block 30 and the piston plate 29. The spring knife 23 pops out under the elastic force of the second spring to cut off the fibers at the knotted part, avoiding the continuous release of fibers at the discharge port 14, causing more fiber knots and resulting in waste.

[0027] A torsion spring is arranged between the rotating plate 19 and the clamping plate 15. Two groups of spring knives 23 are symmetrically placed at both ends of the inner wall of the protective plate 20, and the two groups of spring knives 23 are fixedly connected by a connecting strip 26. A secondary switch 22 is arranged on the inner wall of the protective plate 20. The secondary switch 22 is electrically connected to the power supply. The shape of the slot on the surface of the baffle 25 coincides with the cross-section of the limiting plate 24, and the area is slightly larger than the cross-section of the limiting plate 24. A fourth spring is arranged between the limiting plate 24 and the protective plate 20. When the spring knife 23 pops out, it triggers the secondary switch 22 to cut off the power supply to protect the equipment.

[0028] The movable block 30 can only move in the direction away from the push-pull rod 27. There is a small gap between the movable block 30 and the piston plate 29. The push-pull rod 27 is arranged in a U shape, and the length of the end close to the air cylinder 28 is greater than the length of the air cylinder 28. When knots occur during the weaving process, the push rod 21 will keep moving until the piston plate 29 is pushed out of the air cylinder 28.

[0029] Before the knitting work begins, place two sets of robotic arms 4 on the surface of the slide rail 2. According to the variable data such as the size and tension of the product to be knitted, adjust the horizontal position of the robotic arms 4, and fix the robotic arms 4 on the inner wall of the slide rail 2 through the fixing screws 5. Then insert the clamping plate 16 into the splint 15 to fix the knitting frame 17. Then rotate the fixing ring 10 according to the position of the fixed knitting frame 17, adjust the fixing ring 10 to the corresponding angle, wind the fiber at the discharge port 14 around the hook on the surface of the knitting frame 17, press the main switch 8 to turn on the power. After the power is connected, the equipment starts to operate. The connecting seat 12 rotates to drive the rotor 13 to rotate, and the rotating rotor 13 drives the discharge port 14 to rotate. The rotating discharge port 14 winds the fiber at the discharge port 14 for preliminary knitting. Then, through the rotation of the inner ring 11, the fiber that has completed the preliminary winding and knitting is driven to rotate for further knitting, improving the strength of the fiber. At the same time, after the power is connected, the splint 15 rotates to drive the clamping plate 16 to rotate, and the rotating clamping plate 16 drives the knitting frame 17 to rotate. During the rotation of the knitting frame 17, the free end of the hydraulic rod 9 continuously moves, driving the knitting frame 17 to move. The knitting frame 17 continuously moves during the rotation, achieving the effect of winding and knitting the fiber.

[0030] At the same time, when the splint 15 rotates, it will drive the rotating plate 19 to rotate. The rotating rotating plate 19 presses the inclined surface of the push rod 21 to push the push rod 21 to move. After the push rod 21 moves, it resets under the elastic force of the elastic member. The reset push rod 21 drives the push-pull rod 27 to move. The moving push-pull rod 27 drives the piston plate 29 to slide in the air cylinder 28. Since the movable block 30 cannot be opened at this time, only a small amount of gas passes through the gap on the surface of the piston plate 29, so that the piston plate 29 can only move slowly. The slowly moving piston plate 29 slows down the reset speed of the push rod 21. When an accidental knot occurs in the fiber between the discharge port 14 and the knitting frame 17 during the knitting process of the knitting equipment, the knotted fiber jams the knitting frame 17, causing the splint 15 to be unable to continue driving the rotating plate 19 to rotate. The rotating plate 19 no longer presses the push rod 21 through rotation. During the slow reset process of the push rod 21, it drives the piston plate 29 to continue moving until the piston plate 29 disengages from the air cylinder 28. After the piston plate 29 disengages from the air cylinder 28, the push rod 21 quickly moves in the reset direction under the elastic force of the elastic member. The moving push rod 21 drives the baffle 25 to move towards the guard plate 20 until the groove on the surface of the baffle 25 aligns with the bottom of the limit plate 24. The limit plate 24 pops out in the direction away from the spring knife 23 under the elastic force of the fourth spring, releasing the limit on the spring knife 23. The released spring knife 23 pops out under the elastic force of the second spring. The popped spring knife 23 cuts off the knotted part of the fiber, preventing waste of fiber caused by the discharge port 14 still releasing fiber after the fiber is knotted. At the same time, the popped spring knife 23 contacts the sub-switch 22, triggering the sub-switch 22 to cut off the power supply of the equipment and protecting the equipment.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
