[0023] like Figures 1 to 3 As shown, the present invention provides a carbon fiber product manufacturing apparatus and a manufacturing method. The carbon fiber product manufacturing apparatus includes a frame 1, a support mechanism 2, and a coating mechanism 3. The support mechanism 2 includes a lamination platform 21, a first driving component 22, and a vacuum pump. The lamination platform 21 is slidably connected to the frame 1 in a vertical direction and is used to support the carbon fiber mold. The first driving component 22 is mounted on the frame 1 and is drively connected to the lamination platform 21, and can drive the lamination platform 21 to move in a vertical direction. The lamination platform 21 has a receiving cavity, and the top plate of the lamination platform 21 has a plurality of first through holes spaced apart, all of which communicate with the receiving cavity. The vacuum pump is connected to the receiving cavity and is used to provide negative pressure to the receiving cavity. The coating mechanism 3 includes a first support component 31, a pressing component, and a second driving component 32. The first support component 31 is fixed. The first support member 31 is located directly above the lamination platform 21. The clamping member is slidably connected to the frame 1 in the vertical direction and is located directly above the first support member 31. The second drive member 32 is installed on the frame 1 and is connected to the clamping member in a transmission manner. The second drive member 32 can drive the clamping member to move in the vertical direction so that the clamping member can abut against the top surface of the first support member 31. A silicone film is disposed between the first support member 31 and the clamping member. The first support member 31 is provided with a first clearance hole, and the clamping member is provided with a second clearance hole. The first clearance hole is directly opposite the second clearance hole. The top plate of the lamination platform 21 can abut against the bottom surface of the first support member 31. Part of the carbon fiber mold can pass through the first clearance hole and the second clearance hole so that the silicone film covers the carbon fiber mold. Compared to existing technologies, this carbon fiber product production device forms a sealed space through a silicone film and a lamination platform 21. A vacuum pump is used to create a vacuum, and the lamination is completed in one suction and pressing process. The vacuum pump back-blowing can separate the carbon cloth adhered to the surface of the carbon fiber mold from the silicone film, improving production efficiency. At the same time, the silicone film is uniformly stretched and tightly adhered to the curved surface of the carbon fiber mold under vacuum negative pressure, and the carbon cloth is squeezed to adhere to the curved surface of the carbon fiber mold, which can avoid wrinkles and air bubbles, improve laying accuracy, and enhance the bonding effect.
[0024] It should be noted that the silicone film used in this embodiment is a high-elastic silicone film with a matching width of 800mm×800mm and a thickness of 1mm-3mm. It can be directly covered on the surface of carbon cloth. Utilizing its ≥200% elongation and ≥500% tear elongation, it can be uniformly stretched and tightly adhered to complex curved surfaces under vacuum negative pressure, avoiding local pressure loss and air bubble residue caused by wrinkles in traditional vacuum bags.
[0025] Optionally, the carbon fiber product manufacturing apparatus further includes several guide rods 4, which are spaced apart circumferentially on the frame 1 along the lamination platform 21. The lamination platform 21 and the clamping components are slidably fitted onto the guide rods 4. Specifically, the carbon fiber product manufacturing apparatus is provided with four guide rods 4, which are fixed at the four corners of the frame 1 respectively. The guide rods 4 extend vertically, ensuring that the lamination platform 21 and the clamping components move vertically and preventing offset and tilting.
[0026] Optionally, the carbon fiber product manufacturing device further includes a second support 5, a guide rail 6, and a slider 7. The second support 5 is slidably sleeved on the guide rod 4, the guide rail 6 is fixed to the second support 5 and extends along the first direction, the slider 7 is fixed to the bottom plate of the lamination platform 21 and slidably connected to the guide rail 6, the second support 5 is provided with a clearance groove, and the driving end of the first driving member 22 can pass through the clearance groove and abut against the bottom plate of the lamination platform 21. The first direction is perpendicular to the vertical direction. Specifically, in this embodiment, the first direction is the front-to-back direction of the device. An opening 101 is provided in front of the carbon fiber product production device. The carbon fiber product production device is provided with two guide rails 6 and two sliders 7. The two guide rails 6 and the two sliders 7 are arranged one-to-one. The two guide rails 6 are respectively arranged on both sides of the second support member 5. The carbon fiber product production device also includes a handle. The handle is installed at the front end of the lamination platform 21. By pulling the handle, the operator can extend the lamination platform 21 out of the frame 1 for easy handling of carbon fiber molds. The second support member 5 is U-shaped. The driving end of the first driving member 22 moves vertically, accurately passes through the cavity of the clearance groove, crosses the physical barrier of the second support member 5, and finally presses tightly onto the bottom plate of the lamination platform 21, thus optimizing the spatial layout of the whole machine.
[0027] Optionally, the clamping component includes a clamping frame 33, two connecting blocks 34, and several connecting rods 35. The clamping frame 33 is provided with a second clearance hole. The two connecting blocks 34 are spaced apart on both sides of the clamping frame 33 along a second direction. The connecting rods 35 connect the clamping frame 33 and the connecting blocks 34. Both the clamping frame 33 and the connecting blocks 34 are slidably sleeved on the guide rod 4. The second driving component 32 is connected to the connecting blocks 34. The first direction and the vertical direction are perpendicular to each other (the first direction and the vertical direction are perpendicular to each other). Figure 1(The direction indicated by the middle arrow). Specifically, in this embodiment, the second direction is the left-right direction of the device. The first support member 31 and the pressure frame 33 are both rectangular frame structures. The first support member 31 has a first clearance hole in the middle, and the pressure frame 33 has a second clearance hole in the middle. The clamping member is provided with four connecting rods 35, and two connecting blocks 34 are respectively provided on the left and right sides of the pressure frame 33. One connecting block 34 is connected to one side of the corresponding pressure frame 33 through two connecting rods 35, and the other connecting block 34 is connected to one side of the corresponding pressure frame 33 through another two connecting rods 35. The connecting block 34 serves as... The intermediate hub for force transmission is rigidly connected to the pressure frame 33 through parallel connecting rods 35, thereby forming a stable gate-shaped force-bearing frame. The film-coating mechanism 3 is equipped with two second driving components 32, which are correspondingly set with two connecting blocks 34. The output end of the second driving component 32 (such as a cylinder or electric push rod) is fixedly connected to the connecting block 34. By pulling the connecting block 34, the entire pressure frame 33 assembly is driven to move smoothly up and down along the guide rod 4, ensuring that the pressure frame 33 always maintains a horizontal posture during the lifting and lowering process, preventing tilting and avoiding uneven force distribution.
[0028] Optionally, the carbon fiber product manufacturing device also includes several bearings 8, with bearings 8 installed between the second support member 5 and the guide rod 4, and between the connecting block 34 and the guide rod 4. Specifically, several high-performance bearings 8 (linear bearings 8 or self-lubricating copper sleeves) are embedded between the second support member 5 and the guide rod 4, and between the connecting block 34 and the guide rod 4. As key intermediate transmission components, the bearings 8 transform the original dry metal-to-metal friction into a low-resistance rolling or sliding friction pair, ensuring that the pressing assembly maintains extremely high motion accuracy and smoothness in high-frequency reciprocating motion, further optimizing the guide connection structure.
[0029] Optionally, the carbon fiber product production device also includes a number of elastic elements 9, which are arranged one-to-one with a number of guide rods 4. The pressure frame 33 is provided with a number of second through holes, which are arranged one-to-one with a number of guide rods 4. The diameter of the second through holes is larger than the diameter of the guide rods 4. The elastic element 9 is sleeved on the guide rods 4. One end of the elastic element 9 abuts against the end face of the bearing 8 between the connecting block 34 and the guide rod 4. The other end of the elastic element 9 passes through the second through hole and abuts against the first support member 31. The elastic element 9 is configured to always drive the pressure frame 33 to move away from the first support member 31. Specifically, in order to ensure that the pressure frame 33 can quickly and reliably reset after the pressing operation is completed, so as to avoid obstructing the feeding and discharging action of the stacking platform 21, several second through holes are provided on the pressure frame 33. The diameter of the through hole is specially designed to be slightly larger than the outer diameter of the guide rod 4, so as to form a certain radial gap between the two, which can eliminate the direct rigid constraint of the guide rod 4 on the pressure frame 33. The elastic element 9 is specifically sleeved on the outer periphery of the guide rod 4. Its upper end abuts against the end face of the bearing 8 fixed on the connecting block 34, and its lower end passes through the second through hole on the pressure frame 33 and directly abuts against the first support member 31 below. The elastic element 9 is always under pressure, generating a constant preload. The preload force acts in the opposite direction on the connecting block 34 through the bearing 8, and then pulls the pressure frame 33 upward through the connecting rod 35. When the second driving member 32 releases pressure or retracts, the pressure frame 33 is no longer subject to downward driving force. At this time, under the elastic force of the elastic member 9, the pressure frame 33 immediately floats upward along the guide rod 4 and automatically disengages from the contact with the first support member 31. Furthermore, the elastic member 9 is a compression spring.
[0030] Optionally, the carbon fiber product manufacturing apparatus also includes a hot air blowing mechanism 10, which is mounted on the frame 1 and positioned directly above the laminating mechanism 3. The hot air blowing mechanism 10 is used to blow hot air onto the silicone film. This arrangement, integrating the hot air blowing mechanism 10 at the top of the frame 1, can accelerate the softening of the carbon cloth and improve the bonding effect.
[0031] Optionally, the carbon fiber product manufacturing apparatus further includes a support 11 and several pressing mechanisms. The support 11 is connected between the frame 1 and the hot air blowing mechanism 10. The pressing mechanism includes a third driving member 12 and a pressing block 13. The third driving member 12 is mounted on the support 11 and is connected to the pressing block 13 in a transmission manner. The length of the first support member 31 is greater than the length of the pressing member. The third driving member 12 can drive the pressing block 13 to press against the top surface of the first support member 31 to press the silicone film. Specifically, the hot air blowing mechanism 10 is connected to the frame 1 via the bracket 11, which also serves as the mounting base for the pressing mechanism. In this embodiment, the carbon fiber product production device is equipped with two pressing mechanisms located behind the bracket 11. The two pressing mechanisms are arranged at intervals along the length of the bracket 11. The length of the first support member 31 is designed to be significantly greater than the length of the pressure frame 33, so that when the pressure frame 33 presses the first support member 31, the rear edge area of the first support member 31 is exposed. The third drive member 12 is activated, driving the pressure block 13 to descend vertically via the transmission rod. The pressure block 13 presses the silicone film tightly onto the top surface of the first support member 31, forming a double seal with the pressure frame 33, thus creating conditions for the subsequent vacuuming process.
[0032] Furthermore, the first support member 31 is provided with a sealing groove along the circumference, and the pressure frame 33 is provided with a sealing strip along the circumference; or, the first support member 31 is provided with a sealing strip along the circumference, and the pressure frame 33 is provided with a sealing groove along the circumference, and the sealing strip can be disposed within the sealing groove. Specifically, a continuous sealing groove is formed along the circumference on the top surface of the first support member 31, and the cross-section of the sealing groove is trapezoidal or rectangular to accommodate the sealing strip. Correspondingly, a sealing strip is fixed along the circumference on the bottom surface of the pressure frame 33, and the sealing strip is made of silicone or EPDM rubber with excellent resilience. When the pressure frame 33 moves downward under the drive of the second drive member 32 and presses against the first support member 31, the sealing strip on the pressure frame 33 is precisely embedded in the sealing groove on the first support member 31. The sealing strip undergoes elastic deformation, filling the internal gap of the sealing groove, thereby forming a physical barrier with excellent airtightness between the pressure frame 33 and the first support member 31. This "groove-strip" matching structure can not only effectively block external air from entering the sealed space, but also maintain stable sealing performance during repeated opening and closing, preventing carbon fiber product molding defects caused by vacuum leakage, and providing a reliable negative pressure environment for the vacuuming process.
[0033] Optionally, the carbon fiber product manufacturing apparatus further includes a collecting roller 14 and a cutting assembly 15. The collecting roller 14 is rotatably connected to the frame 1, and the cutting assembly 15 is mounted on the frame 1. The collecting roller 14 and the cutting assembly 15 are located on opposite sides of the first support member 31. The collecting roller 14 is used to wind up the silicone film, and the cutting assembly 15 is used to cut the silicone film. Specifically, the collecting roller 14 is rotatably connected to the frame 1 via bearing 8 and is driven by a stepper motor or torque motor. The collecting roller 14 is located at the rear of the frame 1 and is used to collect silicone film waste that has been coated. The cutting assembly 15 is installed at the front of the frame 1 and is distributed opposite to the collecting roller 14. The operator feeds the silicone film into the device through the opening 101 and places it between the first support member 31 and the pressure frame 33. The silicone film is laterally cut by the cutting assembly 15 (pneumatic gate or rotary cutter). When the silicone film is damaged during use, the first support member 31 separates from the pressure frame 33, the collecting roller 14 starts, and peels the used silicone film from the first support member 31 and winds it up for storage by rotating tension. This enables the cutting and storage of silicone film and improves production continuity.
[0034] Optionally, the carbon fiber product manufacturing apparatus also includes a seal, which is disposed between the lamination platform 21 and the first support member 31. Specifically, the seal is fixed circumferentially to the edge of the lamination platform 21. When the lamination platform 21 is lifted by the first drive member 22 and comes into contact with the first support member 31, the seal is compressed and undergoes elastic deformation, thereby filling the microscopic gaps at the contact surface between the two. This creates a reliable gas barrier around the lamination platform 21, ensuring that the vacuum level inside the lamination platform 21 can reach and be maintained at the high vacuum required by the process during subsequent molding, preventing external air from seeping in and disrupting the negative pressure environment. Further, the seal is preferably a sealing ring or gasket made of oil-resistant and corrosion-resistant nitrile rubber or fluororubber.
[0035] The present invention also provides a method for producing carbon fiber products. The carbon fiber product production apparatus in the above embodiments includes the following steps: S1. attaching a carbon cloth of the corresponding size to a carbon fiber mold; S2. placing the carbon fiber mold with the attached carbon cloth on a lamination platform 21; S3. a first driving member 22 drives the lamination platform 21 to rise and press against the bottom surface of the first support member 31, a vacuum pump generates negative pressure, and through the first through hole and the receiving cavity, adsorbs a silicone film onto the carbon fiber mold to tightly adhere the carbon cloth to the carbon fiber mold. After the vacuuming time lasts for 10 seconds, the first driving member 22 drives the lamination platform 21 to descend and remove the carbon fiber mold. Specifically, S1. Carbon cloth of the corresponding size is attached to the carbon fiber mold in a specified order according to the special vacuum lamination standard; S2. The carbon fiber mold with attached carbon cloth is placed on the lamination platform 21 in a specified order according to the lamination standard. It can accommodate various carbon fiber molds such as frames, forks, handlebars, and seatposts, improving the versatility of the device; S3. The first driving component 22 drives the lamination platform 21 to rise and press against the bottom surface of the first support component 31. After bonding, the vacuum pump generates negative pressure. Through the pipe and the receiving cavity in the lamination platform 21, the silicone film is adsorbed onto the carbon fiber mold, thereby tightly bonding the carbon cloth and the carbon fiber mold. After the vacuuming time lasts for 10 seconds, the vacuum pump inputs gas for 2 seconds to break the vacuum environment, separating the silicone film from the laminated part (the bonding structure of carbon cloth and carbon fiber mold) and the lamination platform 21. The first driving component 22 drives the lamination platform 21 to fall and remove the laminated part.
