TECHNICAL FIELD

[0001] The application relates to the technical field of carbon fiber product production, in particular to a carbon fiber product production line. BACKGROUND

[0002] The carbon fiber product includes a full carbon fiber product and a composite carbon fiber product. In the production of the composite carbon fiber product, a mold is used to first injection mold a carbon fiber part, and then the injection molded carbon fiber part is placed in another mold. The cavity of the mold includes a first chamber and a second chamber. The first chamber is shaped to match the carbon fiber part, and the second chamber is shaped to match a non-carbon fiber part. During injection molding, the injection molded carbon fiber part is placed in the first chamber, and the non-carbon fiber material is placed in the second chamber. Then, the injection molding process is performed to injection mold the non-carbon fiber material on the carbon fiber part, thereby forming the composite carbon fiber product.

[0003] Since the carbon fiber part needs to be pressure cast and the non-carbon fiber part needs to be injection molded each time a carbon fiber product is produced, the production process is complicated and inefficient. CONTENT OF THE UTILITY MODEL

[0004] The application aims to provide a carbon fiber product production line which can pressure cast and injection mold a composite carbon fiber product at one time, and the production process is simple, fast and efficient.

[0005] The carbon fiber product production line provided by the application adopts the following technical scheme:

[0006] The carbon fiber product production line comprises a feeding device, an oven, a mold and a conveying device. The feeding device, the oven and the mold are sequentially arranged. The feeding device is used to convey a thermoplastic carbon fiber plate to the conveying device. The conveying device is used to convey the thermoplastic carbon fiber plate to the position of the oven. The oven is used to soften the thermoplastic carbon fiber plate. The conveying device can convey the softened thermoplastic carbon fiber plate to the mold.

[0007] The mold comprises a front mold and a rear mold. The rear mold can move towards the front mold. The front mold is provided with a first groove and a second groove. The rear mold is provided with a first protrusion and a second protrusion. The first protrusion can be inserted into the first groove and form a first cavity between the first protrusion and the inner wall of the first groove. The second protrusion can be inserted into the second groove and form a second cavity between the second protrusion and the inner wall of the second groove. The first cavity and the second cavity are communicated.

[0008] Optionally, the feeding device includes a feeding rack, a suction cup assembly, and a first linear guide rail. The suction cup assembly is fixed to the output end of the first linear guide rail and can move towards or away from the feeding rack. The feeding rack is used to place several thermoplastic carbon fiber sheets, and the suction cup assembly is used to adsorb the thermoplastic carbon fiber sheets.

[0009] Optionally, the suction cup assembly includes a mounting bracket and a plurality of suction cups. The mounting bracket is fixed to the output end of the first linear guide rail, and at least four suction cups are provided, with the at least four suction cups arranged in a rectangular pattern on the mounting bracket.

[0010] Optionally, the feeding rack includes a feeding platform and limiting posts, and at least four limiting posts are provided. The at least four limiting posts are distributed in a rectangular array, and several of the limiting posts are fixed on the feeding platform.

[0011] Optionally, the transport device includes a three-dimensional moving platform, a clamp, and a rotating component. The clamp is rotatably connected to the output end of the three-dimensional moving platform, and the output end of the rotating component is fixedly connected to the clamp to drive the clamp to rotate.

[0012] Optionally, the oven includes a housing, a cover, and a heating element. The housing has an opening on one side, the cover is disposed on the housing and used to close the opening, the heating element is disposed inside the housing and used to heat the thermoplastic carbon fiber sheet, and the top surface of the housing has a clearance groove adapted to the clamp.

[0013] This application uses an oven to soften and heat thermoplastic carbon fiber sheets, then places the softened sheets in a first groove and uses a first protrusion to die-cast the sheets. After the front and rear molds are closed, hot-melt material is injected into a second cavity, thus achieving die-casting and injection molding on the same mold. This facilitates the production of composite carbon fiber products, eliminating the need for two separate molds to produce the carbon fiber and non-carbon fiber parts, making production convenient and efficient.

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0022] A carbon fiber product production line, with reference to Figure 1 The system includes a feeding device 1, an oven 2, a mold 3, and a conveying device 4, arranged sequentially. Several thermoplastic carbon fiber sheets are stacked on the feeding device 1, which picks up the topmost sheet. The conveying device 4 then clamps and transports the picked-up sheet to the oven 2, where it is heated and softened. The conveying device 4 then transports the softened sheet to the mold 3. During mold closing, the mold 3 performs die casting on the softened sheet. After mold closing, injection molding is performed, injecting hot-melt material into the mold 3 so that the non-carbon fiber portion is formed together with the thermoplastic carbon fiber sheet. This facilitates the production of composite carbon fiber products. Since the non-carbon fiber portion and the carbon fiber portion are formed together in the same mold 3, they can be heated and cooled together, significantly reducing the production time and increasing the production efficiency of composite carbon fiber products.

[0023] Since most of the non-carbon fiber parts are made of materials such as plastic, the injection molding temperature is lower than the die-casting temperature of the thermoplastic carbon fiber sheet. Therefore, the thermoplastic carbon fiber sheet is first heated in a heating box to reach the die-casting temperature and soften it. This makes it easier to die-cast the thermoplastic carbon fiber sheet during the mold closing process of mold 3, without the need for mold 3 to raise the temperature again to soften the thermoplastic carbon fiber sheet. Only the injection temperature needs to be maintained, which is convenient to use.

[0024] ReferenceFigure 2 and Figure 3 Specifically, mold 3 includes a front mold 31 and a rear mold 32. The rear mold 32 can move towards or away from the front mold 31. In this embodiment, the rear mold 32 can be moved by a hydraulic cylinder. Other methods can also be used in other embodiments. The front mold 31 has a first groove 311 and a second groove 312. The rear mold 32 is fixedly provided with a first protrusion 321 and a second protrusion 322. The first protrusion 321 corresponds to the position of the first groove 311, and the second protrusion 322 corresponds to the position of the second groove 312. When the rear mold 32 and the front mold 31 are closed, the first protrusion 321 is inserted into the first groove 311, and the second protrusion 322 is inserted into the second groove 312. A first cavity (not shown in the figure) is formed between the outer wall of the first protrusion 321 and the inner wall of the first groove 311, and a second cavity (not shown in the figure) is formed between the inner wall of the second groove 312 and the outer wall of the second protrusion 322.

[0025] In the production of composite carbon fiber products, the softened thermoplastic carbon fiber sheet is first transported to the first groove 311 by the transport device 4 and placed therein. Then, the front mold 31 and the rear mold 32 are closed, so that the first protrusion 321 is inserted into the first groove 311 and the second protrusion 322 is inserted into the second groove 312. When the first protrusion 321 is inserted into the first groove 311, the softened thermoplastic carbon fiber sheet is die-cast. After the front mold 31 and the rear mold 32 are closed, the thermoplastic carbon fiber sheet initially forms a preset shape. Then, hot melt material is injected into the second cavity formed at this time through the injection port set on the mold 3. The molten material fills the second cavity and comes into close contact with the thermoplastic carbon fiber sheet in the first cavity. After the hot melt plastic and the thermoplastic carbon fiber sheet are cooled, a complete composite carbon fiber product is formed.

[0026] Reference Figure 1 and Figure 4 The feeding device 1 includes a feeding rack 11, a suction cup assembly 12 and a first linear guide rail 13. A carbon fiber product production line also includes a frame 5. The first linear guide rail 13 is fixed on the frame 5. The suction cup assembly 12 is installed at the output end of the first linear guide rail 13. The suction cup assembly 12 is driven by the first linear guide rail 13 to move towards or away from the feeding rack 11.

[0027] Specifically, the loading rack 11 is fixed on the ground, the first linear guide rail 13 and the suction cup assembly 12 are located above the loading rack 11, and several thermoplastic carbon fiber sheets are stacked on the loading rack 11. When it is necessary to make composite carbon fiber products, the first linear guide rail 13 drives the suction cup assembly 12 to move downward, so that the suction cup assembly 12 adsorbs the thermoplastic carbon fiber sheet located at the top. After adsorption, the first linear guide rail 13 drives the thermoplastic carbon fiber sheet to move upward, so that it is suspended in the air, and then the suspended thermoplastic carbon fiber sheet is transported and processed by the transport device 4.

[0028] Specifically, the loading rack 11 includes a loading platform 111 and limiting posts 112. At least four limiting posts 112 are provided, and the at least four limiting posts 112 are distributed in a rectangular array. The thermoplastic carbon fiber sheets are placed on the loading platform 111 and located between the limiting posts 112. By setting the limiting posts 112, the stacked thermoplastic carbon fiber sheets are limited, reducing the possibility of the stacked thermoplastic carbon fiber sheets tipping over due to environmental factors.

[0029] The suction cup assembly 12 includes a mounting frame 122 and a plurality of suction cups 121. The mounting frame 122 is fixed to the output end of the first linear guide rail 13, and the suction cups 121 are fixed to the mounting frame 122. At least four suction cups 121 are provided, arranged in a rectangular pattern. This rectangular arrangement of the suction cups 121 ensures more stable adsorption of the thermoplastic carbon fiber sheet, reducing the likelihood of the sheet detaching from the suction cups 121. In this embodiment, a pneumatic vacuum suction cup 121 is used. In other embodiments, other suction cups 121 can be used, as long as they can stably adsorb the thermoplastic carbon fiber sheet.

[0030] Reference Figure 5 The transport device 4 includes a three-dimensional moving platform 41, a clamp 42, and a rotating component 43. The three-dimensional moving platform 41 is fixed on the frame 5. The clamp 42 is rotatably mounted on the output end of the three-dimensional moving platform 41. The rotating component 43 is fixed on the output end of the moving platform, and the output end of the rotating component 43 is fixed on the clamp 42 to drive the clamp 42 to rotate. In this embodiment, the rotating component 43 is a motor.

[0031] Specifically, after the thermoplastic carbon fiber sheet is picked up by the suction cup 121, the three-dimensional moving platform 41 moves the clamp 42 to a position corresponding to the thermoplastic carbon fiber sheet. Then, the rotating component 43 rotates the clamp 42 to make it horizontal. The three-dimensional moving platform 41 then moves the clamp 42 to insert the thermoplastic carbon fiber sheet into the clamp 42. At this point, the clamp 42 clamps tightly, and the suction cup 121 stops adsorbing the thermoplastic carbon fiber sheet. The clamp 42 is then rotated to make the thermoplastic carbon fiber sheet vertical. The three-dimensional moving platform 41 moves the clamp 42 to the oven 2 position, where the oven 2 heats and softens the thermoplastic carbon fiber sheet. The softened thermoplastic carbon fiber sheet is then moved to the mold 3 position by the three-dimensional moving platform 41. Through the cooperation of the three-dimensional moving platform 41 and the rotating component 43, the softened thermoplastic carbon fiber sheet is inserted into the first groove 311, ready for processing.

[0032] Reference Figure 1 and Figure 6Furthermore, the oven 2 includes a housing 21, a cover plate 22, and a heating element 23. The housing 21 has an opening on one side. The cover plate 22 is mounted on the housing 21 and used to close the opening. In this embodiment, the cover plate 22 is rotatably mounted on the housing 21 and is rotated by a motor to achieve the closing and opening of the opening. In other embodiments, the cover plate 22 is slidably mounted on the housing 21 and can be driven to slide by a linear guide rail or other driving method to achieve the closing and opening of the opening of the housing 21. The heating element 23 is fixedly installed inside the housing 21 and is used to heat the thermoplastic carbon fiber sheet. In this embodiment, the heating element 23 can be a heating tube; in other embodiments, other heatable components can also be used.

[0033] A clearance groove 211 is provided on the top surface of the housing 21. The clearance groove 211 is adapted to the clamp 42. When the clamp 42 moves the thermoplastic carbon fiber sheet to the oven 2 position, the cover 22 automatically opens, and the three-dimensional moving platform 41 moves the clamp 42 into the housing 21. The connection between the clamp 42 and the three-dimensional moving platform 41 is located in the clearance groove 211. Then the cover 22 is closed, and the heating element 23 is turned on to heat and soften the thermoplastic carbon fiber sheet. Through the setting of the clearance groove 211, the oven 2... When heating the thermoplastic carbon fiber sheet, the clamp 42 can still clamp the thermoplastic carbon fiber sheet without removing the carbon fiber sheet, placing it in the oven 2 for heating, and re-clamping the thermoplastic carbon fiber sheet. The operation is more convenient. Furthermore, due to the setting of the clearance groove 211, when the clamp 42 clamps the thermoplastic carbon fiber sheet and places it in the box 21, the cover 22 can still close normally, reducing the leakage of heat in the box 21 and ensuring the temperature inside the box 21, which is convenient for heating and softening the thermoplastic carbon fiber sheet.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
