Description

Technical Field

[0001] The present invention relates to the technical field of automated production equipment, and particularly to an automated production equipment for carbon fiber reinforcement sheets. Background Art

[0002] Carbon fiber is widely used as a lightweight and high-strength material. For example, carbon fiber materials are widely used in the production of the hubs of road bicycles. The connection position between the carbon fiber hub body and the spokes is a structurally weak position. The dynamic range that the spoke holes of the hub need to bear is wide, and the typical value is 200N - 1000N / hole, specifically depending on the material, design, and application scenario. The load capacity of carbon fiber hubs can be significantly improved through reinforcement sheets and optimized layup. Therefore, there is a high demand for carbon fiber reinforcement sheets in the production of carbon fiber hubs.

[0003] Carbon fiber reinforcement sheets are formed by stacking and bonding multiple layers of sheet-shaped carbon fiber prepregs. The traditional production process is manual production, which is made through manual handling, stacking, and bonding processes. The quality of the finished product depends on manual experience and skills, with unstable quality, low efficiency, and high labor requirements. To improve efficiency, there are also semi-automatic production equipment on the market that automatically cut carbon fiber materials through automated machinery. However, there are still multiple processes in the application of semi-automatic production equipment that rely on manual processing, which restricts production efficiency and has limited improvement in production capacity. The demand for carbon fiber reinforcement sheets from carbon fiber bicycle manufacturers and hub manufacturers on the market is large. To meet the production needs of enterprises and achieve cost reduction and efficiency improvement, it is urgent to design a device that can automate the production of carbon fiber reinforcement sheets.

[0040] The present invention is further described below through specific implementation modes.

[0041] Reference Figures 1 to 11 As shown, an automated production device for carbon fiber reinforcement sheets includes: a feeding mechanism, a cutting mechanism 2, a positioning tray 3, a delivery mechanism 4, a stacking tray 5, and a material moving robot 7.

[0042] The feeding mechanism is used to provide carbon fiber strips; the cutting mechanism 2 is used to perform cutting actions to cut the carbon fiber strips into sheets; the positioning material tray 3 is provided with a sheet material slot 31 for placing the cut sheets; the feeding mechanism 4 includes a feeding moving assembly 41 and a picking component 42, the picking component 42 is used to pick up and place carbon fiber strips and sheets, the picking component 42 is installed on the feeding moving assembly 41 and is driven by the feeding moving assembly 41 to move between the picking position of the feeding mechanism, the cutting position of the cutting mechanism 2, and the placing position of the positioning material tray 3; the stacking material tray 5 is provided with a stacking slot 51; the material moving robot 7 is used to move the sheets in the sheet material slot 31 to the stacking slot for stacking, and the stacked sheets are bonded to each other to form a carbon fiber reinforcement sheet.

[0043] The loading mechanism in this embodiment includes a raw material tray 1, on which a plurality of parallel guide troughs 11 are provided. The guide troughs 11 are used to place carbon fiber strips. The carbon fiber strips are strip-shaped carbon fiber prepregs. The width of the carbon fiber strips is not greater than the width of the guide troughs 11, so that the width direction of the carbon fiber strips is limited by the guide troughs 11, and the limited carbon fiber strips are moved along the length direction of the guide troughs 11.

[0044] The guide trough 11 is designed to match the width of the corresponding carbon fiber strip material, so that the carbon fiber strip material is restricted to move in a straight line during movement, which greatly reduces the position error during the material movement process, ensures the accuracy of the subsequent cutting position, and makes the specifications of each sheet material obtained by each cutting consistent. The guide trough 11 is provided with a plurality of carbon fiber strip materials, so that multiple carbon fiber strip materials can be obtained at one time during the material collection process and cut synchronously during cutting, and multiple sheet materials can be obtained in one action, which improves production efficiency. Each guide trough 11 adopts a parallel design arrangement method, so that the movement trajectory of each carbon fiber strip material is consistent during the material collection process, ensuring that the specifications of multiple sheet materials obtained in a single cutting are consistent.

[0045] In addition to the above-mentioned embodiments, the feeding mechanism of the present case also includes but is not limited to automatic feeding of carbon fiber strips by conveyor belts, feeding of carbon fiber strips in the form of rolls through guide wheel groups, automatic feeding by mechanical arms, and manual feeding.

[0046] In this embodiment, the cutting mechanism 2 includes a cutter 21 and a bottom plate 22. The cutter 21 moves up and down to perform the cutting action. A knife pad 221 extending in the transverse direction is provided on the bottom plate 22. The knife pad 221 is located at the lower side of the cutter 21. The knife pad 221 receives the cutter 21 when it descends. The knife pad 221 is used to protect the cutting edge of the cutter 21 and better maintain the sharpness of the cutting edge. The knife pad 221 is made of soft material to ensure that the cutter 21 can completely cut the carbon fiber strip material.

[0047] The bottom plate 22 is provided with a plurality of positioning grooves 222, each positioning groove 222 corresponds to the position of each guide trough 11, the horizontal height of the positioning groove 222 is consistent with the height of the corresponding guide trough 11, the groove width of the positioning groove 222 is consistent with the groove width of the corresponding guide trough 11, and the positioning groove 222 receives the strip material moved from the guide trough 11. The positioning groove 222 is provided with a detection hole 223 that runs through the top and bottom, and a sensor 224 is provided below the detection hole 223, and the sensor 224 is used to identify whether there is material in the positioning groove 222. The detection hole 223 is an elongated hole, and the sensor 224 is an infrared distance sensor. The sensor 224 can adjust the light output position relative to the elongated hole, and then adjust the detection position. When the carbon fiber strip material moves to the cutting position, the front section position of the carbon fiber strip material to be cut is limited by the positioning trough 222, which further ensures the accuracy of the cutting position.

[0048] The feeding and moving component 41 in this embodiment includes a moving module 411 and a lifting mechanism 412. The lifting mechanism 412 is installed on the moving module 411 and is driven by the moving module 411 to move back and forth. A number of positioning and recognition devices 4111 for identifying the position of the lifting mechanism 412 in the front-back direction are provided on the moving module 411. The material taking component 42 is installed below the lifting mechanism 412. The quantity arrangement and position setting of the positioning and recognition devices 4111 are carried out according to the positions where the material taking component 42 actually needs to stay.

[0049] The material taking component 42 in this embodiment further includes an installation frame 423. The middle part of the installation frame 423 has a long opening 4231 extending in the transverse direction and penetrating up and down. A number of suction cup blocks 421 are arranged horizontally and at intervals on the installation frame 423 in front of the long opening 4231. A number of positioning blocks 424 are arranged horizontally and at intervals on the installation frame 423 behind the long opening 4231. A suction cup block 421 and a positioning block 424 are arranged corresponding to each other and at intervals in the front-back direction. A clearance 422 is formed between each suction cup block 421 and each positioning block 424. The clearance 422 is used to provide a space for the cutting knife 21 to pass through. The cutting knife 21 passes through the clearance 422 to cut off the carbon fiber strip material obtained by the material taking component 42. The suction cup blocks 421 are machining suction cups. The positioning blocks 424 can be ordinary pressing blocks or machining suction cups can also be selected. The material taking component 42 further includes auxiliary suction cups 425. An auxiliary suction cup 425 is correspondingly arranged at an interval behind a suction cup block 421, and the corresponding suction cup block 421 and the auxiliary suction cup 425 are used to suck the same carbon fiber strip material. Anti-sticking coatings are coated on the bottoms of the suction cup blocks 421, the positioning blocks 424, and the auxiliary suction cups, so that they will not contact and adhere to the carbon fiber strip material.

[0050] When a carbon fiber strip material is obtained by the material taking component 42, the front side is simultaneously adsorbed by the suction cup blocks 421 and the auxiliary suction cups 425. The double-point adsorption can avoid the accidental dropping or sliding of the carbon fiber strip material during the movement, ensuring the accurate landing position of the final carbon fiber strip material. If the positioning blocks 424 adopt machine frame suction cups, the carbon fiber strip material is simultaneously adsorbed by the suction cup blocks 421, the positioning blocks 424, and the auxiliary suction cups 425. The three-point adsorption further improves the moving reliability and position accuracy. In other embodiments, a number of auxiliary suction cups 425 are arranged at intervals behind a suction cup block 421. The auxiliary suction cups 425 are arranged at intervals along a straight line. During the movement, the carbon fiber strip material is adsorbed by the adsorption force at more positions as a whole. The multi-point adsorption further improves the moving reliability and position accuracy. During the cutting process, the carbon fiber strip material is pressed by the suction cup blocks 421 and the positioning blocks 424 in the positioning groove 222, and the cutting knife passes through between the suction cup blocks 421 and the positioning blocks 424 for cutting. When cutting, the carbon fiber strip material is reliably pressed and fixed, ensuring the cutting precision of the cutting knife 21.

[0051] In this embodiment, the positioning tray 3 is arranged on the front side of the cutting mechanism 2. A plurality of sheet slots 31 are provided on the positioning tray 3. The multiple sheet slots 31 are arranged in rows at horizontal intervals. The positions of the rows of sheet slots 31 correspond to the positions of the respective guiding slots 11. There are multiple rows of sheet slots 31 on the positioning tray 3. After a cutting operation is completed, the material taking component 42 will obtain a plurality of sheet materials. The material taking component 42 moves to a placement position corresponding to a row of sheet slots 31, that is, one sheet material is placed below one sheet slot 31. After placing, the material taking component 42 releases, and one row of sheet materials is correspondingly placed into one row of sheet slots 31 at a time, with high action execution efficiency. The multiple rows of sheet slots 31 included in the positioning tray 3 play a buffering role, ensuring that the actions of placing and taking out the sheet materials can be completed according to their respective set rhythms.

[0052] In this embodiment, a waste box 32 is provided on one side of the positioning tray 3. The waste box 32 is used to receive the waste material heads or tails generated during the cutting process.

[0053] In this embodiment, the stacking slot 51 has a multi-layer nested groove structure, and each layer of groove is used to place and position a sheet material. Specifically, the carbon fiber reinforcing sheet in this embodiment is formed by bonding three sheet materials with different widths. Therefore, the corresponding stacking slot 51 has a three-layer groove structure, and the depth of each layer of groove is equal to or slightly less than the thickness of the sheet material. The lower layer of groove corresponds to the sheet material with the narrowest width. The middle layer of groove is formed by expanding the upper edges of the two width sides of the lower layer of groove outward, and the width of the middle layer of groove corresponds to the width of the middle layer of sheet material. The upper layer of groove is formed by expanding the upper edges of the two width sides of the middle layer of groove outward, and the upper layer of groove corresponds to the sheet material with the widest width. When different specifications of sheet materials are inserted into their respective corresponding grooves, they are limited by the grooves, ensuring the accuracy of the placement position of the sheet materials, and thus ensuring the product accuracy of the finally formed carbon fiber reinforcing sheet. According to the different specifications of the carbon fiber reinforcing sheets produced, the specific structure of the stacking slot 51 is adjusted adaptively according to the specifications.

[0054] A material ejecting hole 52 is opened at the bottom of the stacking slot 51. A liftable and movable material ejecting column 53 is provided below the material ejecting hole 52. The material ejecting column 53 rises through the material ejecting hole 52 to eject the material upward from the stacking slot 51. A heater 6 is also provided on one side of the stacking tray 5. The heater 6 is used to heat the stacking tray 5. The heater 6 improves the surface viscosity of the sheet materials formed by cutting the carbon fiber prepreg by increasing the temperature, thereby accelerating the fusion of adjacent sheet materials and making the mutually stacked sheet materials more tightly bond to form a carbon fiber reinforcing sheet. The heater 6 is preferably a heat radiation lamp. The design of the material ejecting hole 52 and the material ejecting column 53 can eject the formed carbon fiber reinforcing sheet from the stacking slot 51, avoiding the problem that the carbon fiber reinforcing sheet cannot be taken out because it adheres to the stacking slot 51.

[0055] This embodiment includes multiple sets of sheet material forming components. One set of sheet material forming components includes a feeding mechanism, a cutting mechanism 2, a positioning tray 3, and a material feeding mechanism 4. Each set of sheet material forming components forms sheet materials of the same or different specifications; the moving range of the material transfer manipulator 7 includes the positioning trays 3 of each set of sheet material forming components. The material transfer manipulator 7 grabs the sheet materials of the same or different specifications on each positioning tray 3 and arranges and stacks them in the stacking grooves of the stacking tray 5.

[0056] In this embodiment, there are also a finished product placement station 8 and a release paper station 9. The moving range of the material transfer manipulator 7 includes the finished product placement station 8 and the release paper station 9. The finished product placement station 8 is used to place carbon fiber reinforcement sheets. The material transfer manipulator 7 can obtain the finished products from the stacking tray 5 and move them to the finished product placement station 8. There are several release papers in the release paper station 9. The material transfer manipulator 7 can obtain the release papers and move them to the finished product placement station 8. The material transfer manipulator 7 includes a three-axis servo moving drive 71 and a suction cup assembly 72. A number of suction cups are arranged in an array on the suction cup assembly 72. A number of sheet material grooves 31 are arranged in an array on the positioning tray 3. A number of stacking grooves 51 are arranged in an array on the stacking tray 5. The suction cups of the suction cup assembly 72, the sheet material grooves 31 of the positioning tray 3, and the stacking grooves 51 of the stacking tray 5 are arranged at the same interval in the array. Therefore, each action of the moving material manipulator 7 transfers a group of sheet materials or carbon fiber reinforcement sheets with an array quantity synchronously, and the working efficiency is high. The carbon fiber reinforcement sheets are obtained by the material transfer manipulator 7 and stacked at the finished product placement station. A layer of release paper is arranged between the upper and lower layers of carbon fiber reinforcement sheets. The release paper is used to separate the carbon fiber reinforcement sheets to prevent adjacent carbon fiber reinforcement sheets from adhering to each other.

[0057] The following further illustrates the present application through the specific working process in this embodiment.

[0058] An automated production process for carbon fiber reinforcement sheets includes the following steps:

[0059] S1. The process of cutting off the material head;

[0060] S11. Carbon fiber strip materials are placed in the respective guiding material grooves 11 of the raw material tray 1. The width of the carbon fiber strip materials is adapted to the width of the guiding material grooves 11 in which they are placed, that is, the width of the carbon fiber strip materials is equal to or slightly smaller than the width of the guiding material grooves 11;

[0061] S12. The feeding and moving assembly 41 drives the material taking component 42 to the material taking position through the moving module 411 and the lifting mechanism 412. Each suction cup block 421 corresponds to each guiding material groove 11 and sucks one end of each carbon fiber strip material. The auxiliary suction cups 425 are spaced behind the suction cup blocks 421 to assist in adsorbing the carbon fiber strip materials;

[0062] S13. The material delivery moving assembly 41 drives the material taking component 42 to the cutting position, during which the suction cup block 421 drives the carbon fiber strip material strip to move along the length direction of the guide trough 11 and pass through the bottom of the cutting mechanism 2;

[0063] S14. The cutter performs a lifting and cutting action. The cutter 21 descends through the clearance gap 422 to cut each carbon fiber strip material in the width direction. The material on the front side of the cut is the material head, and each carbon fiber strip material on the rear side of the cut has a flush end surface; at this time, the material head is adsorbed on the suction cup block 421, the auxiliary suction cup 425 is released, and the material delivery moving component 41 drives the material taking component 42 to move to discard the material head to the waste box 32;

[0064] S2. Flake material production process;

[0065] S21. The material delivery moving assembly 41 drives the material taking component to the material taking position, each suction cup block 421 corresponds to each guide trough 11 and sucks one end of the carbon fiber strip material, and the auxiliary suction cup 425 is spaced at the rear end of the suction cup block 421 to assist in the absorption of the carbon fiber strip material; because the material head has been cut off, the end positions of each carbon fiber strip material are aligned, that is, the reference origin of the carbon fiber strip material in the length direction has an accurate size;

[0066] S22. The material delivery moving assembly 41 drives the material taking component 42 to the cutting position. During this process, the suction cup block drives the carbon fiber strip material to move along the length direction of the guide material trough 11 and pass through the bottom of the cutting mechanism 2; the front section of the carbon fiber strip material is placed in the positioning groove 222, and when the material strip is in the correct position, it can be identified by the sensor 224. If the sensor 224 does not identify the carbon fiber strip material, it means that there is a shortage of material, and the equipment sends out an alarm to notify manual intervention and adjustment. This design can ensure the stable and safe operation of the equipment;

[0067] S23. The cutter 21 performs a lifting and cutting action. When the cutter 21 descends, it passes through the clearance gap 422 to cut each carbon fiber strip material in the width direction. The material on the front side of the fracture is a sheet material, and each carbon fiber strip material on the rear side of the fracture has a flush end surface;

[0068] S24. The auxiliary suction cup is released, the sheet material remains adsorbed on the suction cup block 421, the material delivery moving assembly 41 drives the material taking component 42 to the material placement position, the material taking component 42 is located at the positioning material tray 3, and a suction cup block 421 is correspondingly located above an empty sheet material slot 31, and the suction cup block 421 releases the sheet material so that the sheet body is placed in the sheet material slot 31;

[0069] Since the positioning material tray 3 is provided with multiple rows of sheet material slots 31, the material delivery moving assembly 41 is correspondingly adapted to be provided with multiple material placement positions, and step S2 is repeated to repeatedly fill the empty sheet material slots 31 on the positioning material tray 3;

[0070] In this embodiment, the carbon fiber reinforcing sheet in this embodiment is formed by bonding three sheet materials with different widths. Therefore, three sets of sheet material forming components are provided. The three sets of sheet material forming components process carbon fiber strip materials of three specifications and correspondingly produce sheet materials of three specifications. That is, sheet materials of three specifications are placed on the three positioning trays 3 for subsequent processes to use;

[0071] S3. Stacking and forming process;

[0072] S31. The transfer manipulator 7 moves to the sheet material groove 31 where the sheet material is placed, obtains the sheet material and moves the sheet to the stacking groove 51;

[0073] S32. According to production requirements, a number of sheet materials are stacked in a stacking groove 51, and the heater 6 heats the stacked sheet material tray 5. The sheet material is heated to increase the surface viscosity, and then the stacked sheet materials are bonded to each other to form a carbon fiber reinforcing sheet; In this embodiment, the transfer manipulator 7 respectively grabs the sheet materials of three specifications of the three sets of sheet material forming components, stacks and heats and bonds the sheet materials of the three specifications in the stacking groove 51 in a set order, and finally forms a carbon fiber reinforcing sheet with the required structure;

[0074] S4. Finished product process;

[0075] S41. A carbon fiber reinforcing sheet has been formed in the stacked sheet material tray 5, and the ejector post 53 rises to eject the carbon fiber reinforcing sheet upward from the stacking groove 51. At this time, the carbon fiber reinforcing sheet will be separated from the stacking groove 51;

[0076] S42. The transfer manipulator 7 obtains the ejected carbon fiber reinforcing sheet, and then moves to the finished product placement station 8 for placement;

[0077] S43. The transfer manipulator 7 moves to the release paper station 9 to obtain the release paper, and then moves to the finished product placement station 8 to lay the release paper on the previous layer of carbon fiber reinforcing sheet;
