Description

Technical Field

[0001] The present invention belongs to the technical field of carbon fiber measurement, and particularly relates to an automatic measurement device for carbon fiber. Background Art

[0002] Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. It has the highest heat resistance among all chemical fibers. Made from acrylic and viscose fibers as raw materials, through high-temperature oxidation and carbonization, it is an excellent material for manufacturing high-tech equipment such as aerospace. After the carbon fiber finished product comes out, it needs to be wound and collected by a winding rack. A certain amount of carbon fiber is collected on each winding rack. Therefore, an automatic measurement device is used to automatically measure the length of the carbon fiber to ensure that the required amount of carbon fiber is wound on the winding rack.

[0003] The existing automatic measurement devices for carbon fiber generally feed carbon fiber from one side, then after passing through the automatic measurement station and completing the measurement, it is wound on the corresponding winding rack and taken away. However, after the required amount of carbon fiber is wound on the winding rack, the operator needs to cut the carbon fiber, remove the winding rack, and then install a winding rack without wound carbon fiber to continue collecting the carbon fiber, which is not only time-consuming and laborious, but also reduces the measurement speed, thereby affecting the processing speed of carbon fiber. Summary of the Invention

[0004] The present invention provides an automatic measurement device for carbon fiber, aiming to solve the problem that after the required amount of carbon fiber is wound on the winding rack by the existing automatic measurement device for carbon fiber, the operator needs to cut the carbon fiber, remove the winding rack, and then install a winding rack without wound carbon fiber to continue collecting the carbon fiber, which is not only time-consuming and laborious, but also reduces the measurement speed, thereby affecting the processing speed of carbon fiber.

Detailed implementation manners

[0030] In order to make the objectives, technical solutions and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present invention. The same reference signs in the drawings represent the same components. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 And Figure 2, an embodiment of the present invention provides an automatic measurement device for carbon fiber, which includes a carbon fiber measurement module and a carbon fiber collection module. The carbon fiber measurement module includes a carrier block A1 and a carrier block B2. The sides of the carrier block A1 and the carrier block B2 are connected by a plurality of connecting bars 3. The right side of the carrier block A1 and the carrier block B2 is fixedly connected with a concave frame 4. The bottom of the inner side of the concave frame 4 is fixedly connected with a support rod 5. The output end of the support rod 5 is provided with a mounting sleeve 6 for the carbon fiber to slide through. A pair of mirror-image light-transmitting holes 7 are reserved on both longitudinal sides of the mounting sleeve 6 for the laser signal emitted by the laser emission device 10 to pass through. The upper end of one side of the inner side of the concave frame 4 is provided with a laser receiving device 8 for receiving the laser signal. A signal receiving hole 9 is reserved on the laser receiving device 8 to receive the laser signal emitted by the laser emission device 10. The upper end of the other side of the inner side of the concave frame 4 is provided with a laser emission device 10 for emitting the laser signal. A pair of support rods 11 are arranged on both transverse sides of the concave frame 4. The upper ends of the support rods 11 are fixedly connected with a guiding ring 12 for guiding the sliding carbon fiber. A control panel is arranged on the back of the concave frame 4 for controlling the operation of the entire device.

[0032] When measuring the length of the carbon fiber, the carbon fiber sequentially passes through the guiding ring 12 on the right side, the mounting sleeve 6 and the guiding ring 12 on the left side. The laser emitted by the laser emission device 10 passes through the light-transmitting hole 7 and hits the signal receiving hole 9 on the laser receiving device 8. The laser receiving device 8 receives the laser signal. When the carbon fiber passes through the inside of the mounting sleeve 6, the light-transmitting hole 7 is blocked, and the laser emitted by the laser emission device 10 is blocked. When the laser receiving device 8 cannot receive the laser signal, the control panel starts timing. After the length measurement of the carbon fiber is completed, the laser signal of the laser emission device 10 passes through the light-transmitting hole 7 again and hits the laser receiving device 8, and the control panel stops timing. The product of the calculated time and the constant rotation speed set by the motor A21 or the motor B22 is the length of the carbon fiber, realizing the automatic measurement of the carbon fiber, which not only reduces the labor intensity, but also greatly improves the measurement accuracy, and the overall measurement efficiency is also greatly improved, ensuring the measurement speed of the carbon fiber.

[0033] Refer to Figure 1 And Figure 3, the carbon fiber collection module includes an assembly block C13. The assembly block C13 is fixedly connected to the connecting bar 3 on the side. There is a cavity reserved between one side of the assembly block C13 and the bearing block A1 for assembling the motor D. One side of the assembly block C13 is fixedly connected to a square shell 14. A collection unit is installed in the square shell 14. The collection unit includes a rotating platform C20 rotatably connected to the side of the assembly block C13 farther from the bearing block A1. The rotating platform C20 is rotated by the motor D. A winding frame A17 and a winding frame B18 are installed on the rotating platform C20 to wind and collect the carbon fiber. There is a through groove reserved at the upper end of the side of the square shell 14 farther from the winding frame B18. A guide post 15 is installed in the area close to the through groove. The guide post 15 is installed between the assembly block C13 and the bearing block B2. A restraint 16 is installed on the guide post 15. A longitudinal column 31 is also rotatably connected between the bearing block A1 and the bearing block B2.

[0034] The carbon fiber passes through the bottom of the longitudinal column 31 during the winding and collection interval, and then passes through the restraint 16. The restraint 16 locks and restrains the carbon fiber. After the carbon fiber changes into the square shell 14, the winding frame A17 continuously winds and collects the carbon fiber. After the winding frame A17 finishes collecting, the rotating platform C20 rotates and makes the winding frame A17 move to the previous winding frame B18, and the winding frame B18 moves to the previous winding frame A17. After the position exchange is achieved, the carbon fiber between the winding frame A17 and the winding frame B18 is divided. Then the winding frame B18 winds and collects the carbon fiber, and the winding frame A17 winds and collects the carbon fiber when the carbon fiber is taken away.

[0035] Refer to Figure 4 , the restraint 16 includes a moving platform 161. The moving platform 161 moves horizontally on the guide post 15. A pair of rotating platforms A162 are rotatably connected to the upper end of the moving platform 161. The carbon fiber passes through the outside of the rotating platform A162. A protrusion is installed on the side of the moving platform 161 facing the square shell 14. Rotating bars 163 are rotatably connected to both sides of the protrusion. The rotating bars 163 are arranged obliquely towards the side of the rotating platform A162. A rotating platform B164 is rotatably connected between the upper ends of the pair of rotating bars 163. The rotating platform B164 is located between the pair of rotating platforms A162. Among them, a motor C165 is installed in the middle of the protrusion. The motor C165 is used to drive the rotating bars 163 to rotate. When the carbon fiber passes through the area of the restraint 16, the tension of the carbon fiber can be controlled through the cooperation between the restraint 16 and the carbon fiber. When the winding frame winds and collects the carbon fiber, the carbon fiber passes through the rotating platform A162 and the rotating platform B164. The motor C165 drives the rotating bars 163 to rotate, and then makes the rotating platform B164 press the carbon fiber, so that the carbon fiber has a certain resistance when passing through the restraint 16, assisting the winding frame to wind and collect the carbon fiber, and enabling the carbon fiber to maintain a certain tension, so that the carbon fiber can be densely wound and collected on the winding frame.

[0036] Refer to Figure 5, The winding frame A17 and the winding frame B18 are respectively rotatably connected to both sides of the rotating table C20. The rotating table C20 rotatably connects a rotating rod 23 to the side facing the winding frame B18. A wire interface 231 is reserved at the tail of the rotating rod 23. The winding frame B18 includes a short tube A181. Circular plates 182 are fixedly connected to both sides of the short tube A181. A circular opening 187 is reserved in the center of the circular plate 182 on the side farther from the rotating table C20. Multiple wire ports reserved on the short tube A181 are also installed at the circular opening 187. A through-connection port B188 that penetrates both sides is reserved on the short tube A181 of the winding frame B18. Among them, a sealing block 29 is installed at the circular opening 187. The winding frame B18 is clamped on the rotating rod 23. Multiple tensioning lead screws 30 are installed on the sealing block 29. The tensioning lead screws 30 are threadedly connected to the wire ports. The tensioning lead screw 30 in the center of the sealing block 29 is threadedly connected to the wire interface 231 at the tail of the rotating rod 23 to achieve the locking of the winding frame B18. The winding frame B18 and the winding frame A17 are of the same size and are assembled on one side of the rotating table C20 in the same way. Through this method, both the winding frame A17 and the winding frame B18 can be stably rotatably connected to one side of the rotating table C20, and the assembly and disassembly are very convenient. The assembly and disassembly via the tensioning lead screws 30 are the assembly and disassembly of the winding frame. Motors A21 and B22 are installed on the side of the rotating table C20 farther from the winding frame A17 and the winding frame B18. The motors A21 and B22 respectively drive the rotation of the rotating rod 23 connected to the winding frame A17 and the winding frame B18, driving the rotation of the winding frame to wind and collect the carbon fiber.

[0037] Refer to Figure 5 , A restraint block 183 is movably installed on the outer peripheral surface of the short tube A181 of the winding frame B18 near the side of the rotating table C20. A pressing block 186 is movably installed inside the short tube A181 at the position of the restraint block 183. A through-port 184 connected to the through-connection port B188 is also reserved on the side of the short tube A181 close to the rotating table C20. The pressing block 186 passes through the through-port 184 and is connected to the restraint block 183. The pressing block 186 is constrained at the through-port 184. Among them, the inner diameter of the through-connection port B188 near the circular opening 187 is smaller than the inner diameter of the through-connection port B188 near the pressing block 186, forming a stepped wall. An elastic member A185 is installed between the stepped wall and the pressing block 186. The elastic member A185 always provides a force for the pressing block 186 to approach the side of the rotating table C20. In addition, an inclined wall is reserved at the upper end of the side of the restraint block 183 facing the rotating table C20. This inclined wall is used to lock the carbon fiber between the restraint block 183 and the circular plate 182. The restraint block 183 and the circular plate 182 lock the carbon fiber, and the winding frame can wind and collect the carbon fiber when it rotates.

[0038] Refer to Figure 5 And Figure 6, a dividing unit is installed between the winding frame A17 and the winding frame B18. The dividing unit is located at the center of the rotating table C20 and is used to divide the carbon fiber. Protrusions are installed on both sides of the center of the rotating table C20. One side of the protrusion on the rotating table C20 is provided with a connecting block 28. The connecting block 28 is located between the winding frame A17 and the winding frame B18. Hydraulic rods 24 are installed on the opposite sides of the rotating table C20 and the connecting block 28. The fixed ends of the pair of hydraulic rods 24 are connected by a connecting rod to ensure the stability of the connecting block 28. The two output ends of the pair of hydraulic rods 24 are connected by a dividing blade 27. A pair of connecting columns 25 are fixedly connected to the opposite sides of the pair of protrusions on the rotating table C20 and the connecting block 28 in the vertical direction. The pair of connecting columns 25 on the rotating table C20 and the pair of connecting columns 25 on the connecting block 28 are arranged opposite to each other and separated. Among them, the pair of connecting columns 25 on one side of the rotating table C20 are separated from each other, and the pair of connecting columns 25 on one side of the connecting block 28 are separated from each other. The dividing blade 27 can cross the area between the connecting columns 25 and divide the carbon fiber.

[0039] Refer to Figure 6 , a U-shaped opening is reserved on the lower wall surface of the side of the connecting column 25 on one side of the rotating table C20 that is farther away from the rotating table C20. A rotating piece 26 is rotated on the side of the connecting column 25 on one side of the connecting block 28 that is farther away from the connecting block 28. The other side of the rotating piece 26 is installed in the U-shaped opening. The rotating piece 26 and the connecting column 25 to which it is rotated are connected to each other by a spiral beryllium copper wire. When the rotating piece 26 moves out of the U-shaped opening due to external factors, it automatically returns to its original position under the cooperation of the beryllium copper wire.

[0040] After the carbon fiber touches the rotating blade 26, the rotating blade 26 rotates, and the rotation of the rotating blade 26 will open the through groove, allowing the carbon fiber to move from the outside to between the connecting column 25 and the dividing blade 27 under external factors. When the dividing blade 27 touches the carbon fiber under the traction of the hydraulic rod 24, the rotating blade 26 is blocked by the connecting column 25 and cannot reopen the through groove, and the carbon fiber is constrained between the connecting column 25 and the dividing blade 27. When the dividing blade 27 then performs the dividing activity, the carbon fiber can be cut, achieving the purpose of dividing the carbon fiber. Moreover, the tail of the connecting column 25 on one side of the rotating table C20 and the tail of the connecting column 25 on one side of the connecting block 28 are both inclined towards the side of the dividing blade 27. Under this structure, when the carbon fiber touches the connecting column 25 after being tightened, it will move towards the side of the rotating blade 26 due to the inclination of the connecting column 25, and then insert between the connecting column 25 and the dividing blade 27. And because during the replacement of the winding frame, the carbon fiber must be pressed between the restraint block 183 and the circular plate 182. Therefore, during the division, the carbon fiber must be close to the circular plate 182 near the restraint block 183. With the assistance of the inclined connecting column 25, when the carbon fiber is pressed upwards by the dividing blade 27, under the action of the inclined connecting column 25 and with the assistance of the restraint member 16, the carbon fiber moves, enabling the carbon fiber to be close to the circular plate 182 on the side near the restraint block 183. Due to the installation of the inclined wall on one side of the restraint block 183, the carbon fiber can be locked between the restraint block 183 and the circular plate 182, ensuring that the winding frame performs the winding and rewinding work.

[0041] Refer to Figure 7, the winding frame A17 and the winding frame B18 can rotate around their center lines, and the winding frame A17 and the winding frame B18 can rotate around the center line of the rotating table C20. At the beginning, the winding frame A17 is arranged on the side close to the restraint 16. At this moment, the center line of the winding frame A17 is at the closest position to the restraint 16, and the winding frame B18 is on the other side of the rotating table C20. Then, the distance between the winding frame B18 and the restraint 16 is the largest. The winding frame A17 rotates around its center line to collect carbon fiber. After the carbon fiber is collected, the rotating table C20 rotates, and the winding frame A17 stops rotating and rotates around the center line of the rotating table C20. After rotating half a circle, the winding frame A17 is at the position where the previous winding frame B18 was, and the winding frame B18 is at the position where the previous winding frame A17 was. During this period, the winding frame A17 continuously pulls the carbon fiber. When rotating half a circle, there is a section of carbon fiber between the winding frame A17 and the winding frame B18, and this part of the carbon fiber is between the connecting post 25 and the dividing blade 27. In order to ensure the tensioning effect during this period and prevent the rotating piece 26 from not being able to be driven to open the through groove due to insufficient tension of the carbon fiber, the restraint 16 strengthens the locking effect on the carbon fiber, so that the carbon fiber is tightened when pulling the carbon fiber, and half of the diameters of the winding frame A17 and the winding frame B18 are smaller than the distance between the center line of the connecting post 25 and the center line of the rotating table C20. After the winding frame A17 and the winding frame B18 rotate around the center line of the rotating table C20, the carbon fiber will touch the connecting post 25. At this moment, the carbon fiber can extend between the connecting post 25 and the dividing blade 27, and through the guiding of the guiding post 15, the carbon fiber is guided to the side close to the restraint block 183 and is pressed between the restraint block 183 and the circular plate 182 on the winding frame during rotation. When the dividing blade 27 finishes dividing the carbon fiber, the carbon fiber is locked by the restraint block 183 in advance. At this moment, the winding frame B18 can wind and collect the carbon fiber, and the winding frame A17 stops rotating, then the winding frame A17 can be taken away.

[0042] Refer to Figure 3, in order to facilitate the removal of the winding frame A17, the loading of the winding frame A17 is realized by using the loading platform 19. The bearing block B2 has a communication port A201 reserved in the area of the previous winding frame A17. The radius of the winding frame A17 is smaller than the radius of the communication port A201. The loading platform 19 includes an assembly block D193, and a hub 194 is installed at the lower end of the assembly block D193. There are U-shaped grooves at the bottom of the bearing block A1 and the bearing block B2 in the area of the previous winding frame A17. The assembly block D193 is located in the U-shaped groove. One upper end of the assembly block D193 is fixedly connected with a support seat 191. The support seat 191 is separated from the bearing block B2 for use.
