Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber, and in particular to an automated layer laying device and process for carbon fiber composite material prepreg. Background Art

[0002] Prepreg is a common raw material for carbon fiber products. Its production method is to spread the carbon fiber bundle, melt the prepreg with resin to form a film, and then compound the melted resin film with the carbon fiber layer after the yarn is spread, so that the resin fully impregnates the carbon fiber, thereby completing the processing of carbon fiber prepreg;

[0003] Carbon fiber prepreg has the advantages of light weight and high strength, and is widely used in automobiles, sports and other products, such as carbon fiber bicycles, carbon fiber fishing gear, etc. Currently, most of the carbon fiber prepregs are laid manually, that is, the prepregs cut in advance are manually laid on a support table, stacked layer by layer. This method is simple to operate, but the efficiency and accuracy are low. Therefore, an automated layer laying equipment for carbon fiber composite material prepreg is proposed to facilitate the layer laying of carbon fiber prepreg and improve the laying efficiency and convenience. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an automated layer laying device for carbon fiber composite material prepreg, which is convenient for layer laying of carbon fiber prepreg and improves the laying efficiency and convenience.

[0005] The technical solution adopted by the present invention to solve its technical problems is an automated layer laying equipment for carbon fiber composite material prepregs, comprising a horizontally arranged support table, a storage structure is provided on the upper surface of the support table, a plurality of groups of carbon fiber prepregs are placed on the storage structure, an adsorption moving structure is provided above the storage structure, the adsorption moving structure is used to drive the carbon fiber prepreg in the storage structure to move, a negative pressure structure is fixedly connected to the upper surface of the support table, a rolling structure is provided on one side of the negative pressure structure, the rolling structure is fixedly connected to one side of the moving structure, and a workbench is provided on the side of the support table away from the storage structure.

[0006] By adopting the above technical scheme, when it is necessary to lay carbon fiber prepregs in layers, several groups of carbon fiber prepregs are placed in the storage structure, and the adsorption moving structure is used to drive a group of carbon fiber prepregs placed in the storage structure to move. When the adsorption moving structure moves, it drives the rolling structure to move synchronously. When the adsorption moving structure moves to a certain position, the adsorption moving structure is squeezed and contacted with the negative pressure structure. At this time, the lower surface of the carbon fiber prepreg adsorbed on the adsorption moving structure is in contact with the negative pressure structure, and with the relative movement of the adsorption moving structure and the negative pressure structure, the release paper on the carbon fiber prepreg is adsorbed and detached, which is convenient for the subsequent laying of the carbon fiber prepreg. As the adsorption moving structure continues to move to a certain position, the carbon fiber prepreg is placed on the workbench by relying on the adsorption moving structure, and the laying of a group of carbon fiber prepregs is completed at this time;

[0007] After a group of carbon fiber prepregs are laid, the adsorption moving structure is driven to reset and move, and the adsorption moving structure drives the rolling structure to move synchronously when resetting and moving. When the rolling structure resets and moves to a certain position, the carbon fiber prepreg on the workbench is rolled and heated by the rolling structure, so as to improve the adhesion effect of the carbon fiber prepreg; as the adsorption moving structure is reset to the initial state, the adsorption moving structure is used to drive another group of carbon fiber prepregs in the storage structure to move, and the negative pressure structure is used to separate the release paper on the carbon fiber prepregs again. At the same time, as the adsorption moving structure moves, another group of carbon fiber prepregs are laid on top of the carbon fiber prepregs on the workbench, so that the carbon fiber prepregs can be laid in multiple layers back and forth, and there is no need to manually separate the release paper of the carbon fiber prepregs, so as to improve the laying efficiency and convenience of laying;

[0008] It should be noted that the sticky surface of the carbon fiber prepreg used in the present invention is provided with release paper; and in order to facilitate the separation of the carbon fiber prepreg from the workbench after the lamination is completed, a certain amount of release agent can be applied on the workbench in advance.

[0009] Specifically, the storage structure includes a slot opened on the upper surface of the support platform, a horizontally arranged movable plate is slidably connected in the slot, a plurality of groups of return springs are fixedly connected between the lower surface of the movable plate and the inside of the slot, and a plurality of groups of carbon fiber prepreg are placed on the upper surface of the movable plate.

[0010] By adopting the above technical solution, when the carbon fiber prepreg needs to be layered, the adsorption moving structure moves to the top of the slot, and then moves downward to adsorb the carbon fiber prepreg in the slot. When the adsorption structure is squeezed and contacted with the carbon fiber prepreg on the moving plate, the moving plate is driven to move downward and connected with the slot by sliding, and the return spring moves downward at the same time, so as to improve the contact effect between the adsorption moving structure and the carbon fiber prepreg, and avoid the adsorption moving structure from squeezing and damaging the carbon fiber prepreg.

[0011] After the adsorption moving structure completes the adsorption of the carbon fiber prepreg, the moving plate is driven to move upward by the reset effect of the reset spring, so as to facilitate the subsequent adsorption of the carbon fiber prepreg on the moving plate again.

[0012] Specifically, the adsorption moving structure includes a slide groove, which is located on the side of the support plate, and an electric slider is slidably connected in the slide groove, and an electric telescopic rod is fixedly connected to the upper surface of the electric slider, and a horizontally arranged connecting rod is fixedly connected to the upper end of the electric telescopic rod, and an adsorption plate is fixedly connected to the lower surface of one end of the connecting rod away from the electric telescopic rod, and a cavity is provided inside the adsorption plate, and a plurality of groups of openings connected to the cavity are provided on the lower surface of the adsorption plate, and the adsorption plate is connected to a negative pressure pump.

[0013] By adopting the above technical scheme, when it is necessary to lay the carbon fiber prepreg in layers, the adsorption plate is connected to the negative pressure pump, and the adsorption plate is driven downward by the electric telescopic rod. After the adsorption plate moves down to a certain position, the lower surface of the adsorption plate is squeezed and contacted with the carbon fiber prepreg stored on the movable plate, and the opening of the adsorption plate is adsorbed by the negative pressure pump. After the adsorption is completed, the adsorption plate is driven upward again by the electric telescopic rod, and the electric slider slides in the slide groove to drive the electric telescopic rod and the adsorption plate to move, so as to facilitate the subsequent laying of the carbon fiber prepreg.

[0014] Specifically, the negative pressure structure includes two groups of symmetrically arranged support blocks, the support platform is provided with a positioning groove corresponding to the support block, the support block is slidably connected to the positioning groove, a support spring is connected between the bottom of the support block and the bottom of the positioning groove, an inner sleeve is fixedly connected between the two groups of support blocks, an outer sleeve is rotatably connected to the outer side of the inner sleeve, a plurality of groups of first air suction holes are circumferentially distributed on the inner sleeve, the first air suction holes are connected to the inside of the inner sleeve, a plurality of groups of second air suction holes are circumferentially distributed on the outer sleeve, and a connecting joint connected to the inside of the inner sleeve is provided on one side of one group of the support blocks, and the connecting joint is used to connect to a negative pressure pump;

[0015] Wedge-shaped guide blocks are provided on both sides of the support block away from the inner sleeve, the inclined surface of the wedge-shaped guide blocks corresponds to the lower edge of the adsorption plate, friction wheels are fixedly connected to the outer sides of both ends of the outer sleeve, and a groove corresponding to the friction wheel is provided on the lower surface of the adsorption plate, and a friction transmission plate corresponding to the friction wheel is installed in the groove.

[0016] By adopting the above technical scheme, after the adsorption plate has adsorbed the carbon fiber prepreg, the electric slider slides in the slide groove to drive the adsorption plate to move synchronously. When the adsorption plate moves to a certain position, the lower edge of one side of the adsorption plate is squeezed and contacted with the wedge-shaped guide block, and is squeezed with the movement of the adsorption plate, driving the support block to move downward. When the support block moves downward, the squeeze support spring accumulates force; as the adsorption plate continues to move, the card slot provided on the lower surface of the adsorption plate corresponds to the friction wheel, and at the same time, the friction wheel and the friction transmission plate installed in the card slot are frictionally transmitted, thereby driving the friction wheel to rotate. At this time, the carbon fiber prepreg adsorbed on the lower surface of the adsorption plate is squeezed and contacted with the outer side of the outer sleeve, and is connected to the negative pressure pump by the connecting joint. When the friction wheel rotates, it drives the outer sleeve to rotate. When the outer sleeve rotates, it relies on the second suction hole provided on the outer side of the outer sleeve to adsorb the release paper adhered to the lower surface of the carbon fiber prepreg, and separates the release paper on the lower surface of the carbon fiber prepreg as the outer sleeve rotates, so as to facilitate the subsequent laying of the carbon fiber prepreg and improve the laying efficiency.

[0017] The connecting joint is connected with the negative pressure pump, and air is sucked through the first suction hole and the second suction hole. When the outer sleeve rotates, the release paper is adsorbed and fixed through the second suction hole, and the release paper can be wound, so that the release paper is adsorbed and separated, thereby improving the convenience of separating the release paper;

[0018] When the adsorption plate moves to a certain position by means of the electric slider, the adsorption plate is no longer in contact with the outer sleeve, and the support block is reset and moved upward by means of the reset effect of the support spring. After that, the release paper needs to be manually pulled away from the outer sleeve.

[0019] When the adsorption plate has finished laying the carbon fiber prepreg, the electric slider is used to reset the adsorption plate. When the adsorption plate is reset, the lower edge of one side of the adsorption plate is squeezed and contacted with the wedge-shaped guide block again. As the adsorption plate is reset and moved to the initial state, it is convenient to move and lay the next group of carbon fiber prepreg.

[0020] Specifically, the rolling structure includes symmetrically arranged sliding grooves, the sliding grooves are located on both sides of the support table, the sliding grooves are slidably connected with sliding blocks, the upper surfaces of the sliding blocks are fixedly connected with vertically arranged elastic rods, a heating roller is rotatably connected between the two groups of the elastic rods, the heating roller is in extrusion contact with the upper surface of the workbench, the electric slider is fixedly connected with a fixed rod on one side close to the sliding block, and one end of the fixed rod is fixedly connected with one side of the sliding block;

[0021] A pressing structure is provided on one side of the workbench, and the pressing structure is used to control the connection between the adsorption plate and the negative pressure pump.

[0022] By adopting the above technical solution, after the adsorption plate finishes adsorbing the carbon fiber prepreg, the electric slider moves to drive the fixed rod to move, and the fixed rod moves to drive the sliding block and the heating roller to move synchronously, and the sliding block moves to be slidably connected with the sliding groove. When the adsorption plate moves to the top of the workbench, the electric telescopic rod drives the adsorption plate to move down. After the adsorption plate moves down to a certain position, the adsorption plate contacts the upper surface of the workbench, and at the same time squeezes and opens the pressing structure, and relies on the pressing structure to close the connection between the adsorption plate and the negative pressure pump. At this time, the adsorption plate no longer adsorbs the carbon fiber prepreg, and the carbon fiber prepreg is placed on the upper surface of the workbench.

[0023] After the carbon fiber prepreg is placed on the upper surface of the workbench, the adsorption plate is driven to reset and move by the electric slider. When the electric slider moves, it is driven by the fixed rod to drive the sliding block to move synchronously. When the sliding block resets and moves, it drives the elastic rod and the heating roller to reset and move synchronously. When the heating roller moves to a certain position, the heating roller rolls with the upper surface of the carbon fiber prepreg placed on the upper surface of the workbench. The heating roller increases the viscosity of the carbon fiber prepreg. At the same time, the elastic rod can improve the stability of the heating roller. At the same time, the heating roller can adapt to carbon fiber prepregs of different thicknesses, further improving the convenience of laying the carbon fiber prepreg.

[0024] Specifically, the pressing structure includes a pressing switch, which is located on one side of the workbench. The pressing switch is fixedly connected to the upper surface of the support platform. A pressing plate is provided on the side of the adsorption plate away from the electric telescopic rod. After the adsorption plate moves to the top of the workbench, the pressing plate corresponds to the pressing switch.

[0025] By adopting the above technical solution, when the electric slider drives the adsorption plate to move above the workbench, the electric telescopic rod drives the adsorption plate to move downward. After the adsorption plate moves downward to a certain position, the adsorption plate contacts the upper surface of the workbench, and at the same time, the pressing plate on one side of the adsorption plate contacts the pressing switch by compression, thereby closing the connection between the adsorption plate and the negative pressure pump, and at the same time, the carbon fiber prepreg is laid on the workbench;

[0026] After the carbon fiber prepreg is laid, the adsorption plate is driven to move up by the electric telescopic rod. After the adsorption plate moves up, the pressing plate is no longer in contact with the pressing switch. At this time, the adsorption plate is connected to the negative pressure pump again and moves with the reset of the electric slider, so that the adsorption plate can adsorb the next group of carbon fiber prepreg again and lay multiple layers, thereby improving the convenience of use.

[0027] It should be pointed out that the press switch should use a delay switch to ensure that the carbon fiber prepreg will not be adsorbed onto the adsorption plate again after being detached from the adsorption plate; and the reset time of the delay switch should be less than the time it takes for the electric slider to drive the adsorption plate to reset from above the workbench to above the slot.

[0028] Specifically, a plurality of groups of vertically arranged support legs are provided on the lower surface of the support platform, and reinforcing rods are fixedly connected between adjacent support legs.

[0029] By adopting the above technical solution, the overall stability of the support platform can be improved by relying on a plurality of groups of support legs and reinforcing rods.

[0030] An automated layer laying process for carbon fiber composite material prepreg, using the automated layer laying equipment for carbon fiber composite material prepreg, specifically comprises the following steps:

[0031] Step 1: laying a plurality of groups of carbon fiber prepregs in a storage structure;

[0032] Step 2: The carbon fiber prepreg in the storage structure is adsorbed by the adsorption moving structure, and the carbon fiber prepreg is driven to move toward the workbench;

[0033] Step 3: When the adsorption moving structure moves the carbon fiber prepreg onto the negative pressure structure, the negative pressure structure separates the release paper on the lower surface of the carbon fiber prepreg from the carbon fiber prepreg;

[0034] Step 4: The adsorption moving structure places the carbon fiber prepreg separated from the release paper on a workbench;

[0035] Step 5: While the adsorption structure is reset to the storage structure, the rolling structure moves to roll the prepreg on the workbench to complete the laying of a layer of carbon fiber prepreg;

[0036] Step 6: Repeat steps 1 to 5 until the number of prepreg plies reaches the target requirement.

[0037] Beneficial effects of the present invention:

[0038] The automatic ply laying equipment of carbon fiber composite material prepreg described in the present invention, after the adsorption plate finishes adsorbing the carbon fiber prepreg, the electric slider slides in the slide groove to drive the adsorption plate to move synchronously, and when the adsorption plate moves to a certain position, the second suction hole provided on the outer side of the outer sleeve adsorbs the release paper adhered to the lower surface of the carbon fiber prepreg, and the release paper on the lower surface of the carbon fiber prepreg is separated as the outer sleeve rotates, so as to facilitate the subsequent laying of the carbon fiber prepreg, and at the same time, there is no need to manually separate the release paper of the carbon fiber prepreg, thereby improving the plying efficiency and convenience of plying;

[0039] The automated plying equipment for carbon fiber composite material prepregs described in the present invention relies on the movement of an electric slider to drive the synchronous movement of a heating roller. When the heating roller moves to a certain position, the heating roller rolls against the upper surface of the carbon fiber prepreg placed on the upper surface of the workbench. The stickiness of the carbon fiber prepreg is improved by the heating roller. At the same time, the stability of the heating roller can be improved by the action of the elastic rod. At the same time, the heating roller can adapt to carbon fiber prepregs of different thicknesses, thereby further improving the convenience of plying the carbon fiber prepregs.

[0052] During use, when it is necessary to lay the carbon fiber prepreg in layers, several groups of carbon fiber prepreg are placed in the storage structure, and the adsorption moving structure is used to drive a group of carbon fiber prepreg placed in the storage structure to move. When the adsorption moving structure moves, it drives the rolling structure to move synchronously. When the adsorption moving structure moves to a certain position, the adsorption moving structure is squeezed and contacted with the negative pressure structure. At this time, the lower surface of the carbon fiber prepreg adsorbed on the adsorption moving structure is in contact with the negative pressure structure, and with the relative movement of the adsorption moving structure and the negative pressure structure, the release paper on the carbon fiber prepreg is adsorbed and detached, which is convenient for the subsequent laying of the carbon fiber prepreg. As the adsorption moving structure continues to move to a certain position, the carbon fiber prepreg is placed on the workbench 2 by relying on the adsorption moving structure. At this time, the laying of a group of carbon fiber prepreg is completed;

[0053] After a group of carbon fiber prepregs are laid, the adsorption moving structure is driven to reset and move, and the adsorption moving structure drives the rolling structure to move synchronously when resetting and moving. When the rolling structure resets and moves to a certain position, the carbon fiber prepreg on the workbench 2 is rolled and heated by the rolling structure, so as to improve the adhesion effect of the carbon fiber prepreg; as the adsorption moving structure is reset to the initial state, the adsorption moving structure is used to drive another group of carbon fiber prepregs in the storage structure to move, and the negative pressure structure is used to separate the release paper on the carbon fiber prepreg, and at the same time, as the adsorption moving structure moves, another group of carbon fiber prepregs are laid on top of the carbon fiber prepregs on the workbench 2, so that the carbon fiber prepregs can be laid in multiple layers back and forth, and there is no need to manually separate the release paper of the carbon fiber prepregs, thereby improving the laying efficiency and convenience of laying;

[0054] It should be noted that the sticky surface of the carbon fiber prepreg used in the present invention is provided with release paper; and in order to facilitate the separation of the carbon fiber prepreg from the workbench 2 after the lamination is completed, a certain amount of release agent can be applied on the workbench 2 in advance.

[0055] In order to facilitate the adsorption of the carbon fiber prepreg on the movable plate 4, for example, Figure 1 , Figure 2 , Figure 7 As shown, the present invention also includes that the storage structure includes a slot 3 opened on the upper surface of the support platform 1, a horizontally arranged moving plate 4 is slidably connected in the slot 3, a plurality of groups of return springs 5 ​​are fixedly connected between the lower surface of the moving plate 4 and the inside of the slot 3, and a plurality of groups of carbon fiber prepreg are placed on the upper surface of the moving plate 4.

[0056] During use, when the carbon fiber prepreg needs to be layered, the adsorption moving structure moves to the top of the slot 3, and then moves downward to adsorb the carbon fiber prepreg in the slot 3. When the adsorption structure is squeezed and contacted with the carbon fiber prepreg on the moving plate 4, the moving plate 4 is squeezed and driven to move downward to be slidably connected with the slot 3, and the return spring 5 moves downward at the same time, so as to improve the contact effect between the adsorption moving structure and the carbon fiber prepreg and avoid the adsorption moving structure squeezing and damaging the carbon fiber prepreg;

[0057] After the adsorption moving structure has finished adsorbing the carbon fiber prepreg, the moving plate 4 is driven to move upwards by the reset effect of the reset spring 5, so as to facilitate the subsequent adsorption of the carbon fiber prepreg on the moving plate 4 again.

[0058] In order to facilitate the movement of the carbon fiber prepreg, for example, Figure 1 , 2 As shown in FIG. 3 , the present invention also includes that the adsorption moving structure includes a slide groove 6, the slide groove 6 is located on the side of the support plate, an electric slider 7 is slidably connected in the slide groove 6, an electric telescopic rod 8 is fixedly connected to the upper surface of the electric slider 7, a horizontally arranged connecting rod 9 is fixedly connected to the upper end of the electric telescopic rod 8, an adsorption plate 10 is fixedly connected to the lower surface of one end of the connecting rod 9 away from the electric telescopic rod 8, a cavity is provided inside the adsorption plate 10, a plurality of groups of openings 11 connected to the cavity are provided on the lower surface of the adsorption plate 10, and the adsorption plate 10 is connected to a negative pressure pump.

[0059] During use, when the carbon fiber prepreg needs to be layered, the adsorption plate 10 is connected to the negative pressure pump, and the electric telescopic rod 8 is used to drive the adsorption plate 10 to move downward. After the adsorption plate 10 moves down to a certain position, the lower surface of the adsorption plate 10 is squeezed and contacted with the carbon fiber prepreg stored on the movable plate 4, and the negative pressure pump is used to make the opening 11 of the adsorption plate 10 adsorb the carbon fiber prepreg. After the adsorption is completed, the electric telescopic rod 8 is used to drive the adsorption plate 10 to move upward again, and the electric slider 7 is used to slide in the slide groove 6 to drive the electric telescopic rod 8 and the adsorption plate 10 to move, so as to facilitate the subsequent laying of the carbon fiber prepreg.

[0060] In order to facilitate the separation of the release paper on the lower surface of the carbon fiber prepreg, exemplary, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the present invention also includes that the negative pressure structure includes two groups of symmetrically arranged support blocks 12, the support platform 1 is provided with a positioning groove 13 corresponding to the support block 12, the support block 12 is slidably connected to the positioning groove 13, a support spring 14 is connected between the bottom of the support block 12 and the bottom of the positioning groove 13, an inner sleeve 15 is fixedly connected between the two groups of support blocks 12, an outer sleeve 16 is rotatably connected to the outer side of the inner sleeve 15, a plurality of groups of first air suction holes 17 are circumferentially distributed on the inner sleeve 15, the first air suction holes 17 are communicated with the inside of the inner sleeve 15, a plurality of groups of circumferentially distributed second air suction holes 18 are provided on the outer sleeve 16, and a connecting joint 19 connected with the inside of the inner sleeve 15 is provided on one side of one group of the support blocks 12, and the connecting joint 19 is used to connect to a negative pressure pump;

[0061] The support block 12 is provided with wedge-shaped guide blocks 20 on both sides away from the inner sleeve 15, and the inclined surface of the wedge-shaped guide block 20 corresponds to the lower edge of the adsorption plate 10. The outer sides of both ends of the outer sleeve 16 are fixedly connected with friction wheels 21. The lower surface of the adsorption plate 10 is provided with a groove 22 corresponding to the friction wheel 21, and a friction transmission plate corresponding to the friction wheel 21 is installed in the groove 22.

[0062] When in use, after the adsorption plate 10 has finished adsorbing the carbon fiber prepreg, the electric slider 7 slides in the slide groove 6 to drive the adsorption plate 10 to move synchronously. When the adsorption plate 10 moves to a certain position, the lower edge of one side of the adsorption plate 10 is squeezed and contacted with the wedge-shaped guide block 20, and as the adsorption plate 10 moves and squeezes, the support block 12 is driven to move downward. When the support block 12 moves downward, the support spring 14 is squeezed to store force; as the adsorption plate 10 continues to move, the card slot 22 provided on the lower surface of the adsorption plate 10 corresponds to the friction wheel 21, and at the same time, the friction wheel 21 and the friction wheel installed in the card slot 22 are engaged with each other. The transmission plate friction transmission drives the friction wheel 21 to rotate. At this time, the carbon fiber prepreg adsorbed on the lower surface of the adsorption plate 10 is squeezed and contacted with the outer side of the outer sleeve 16, and is connected to the negative pressure pump by the connecting joint 19. When the friction wheel 21 rotates, it drives the outer sleeve 16 to rotate. When the outer sleeve 16 rotates, the second suction hole 18 provided on the outer side of the outer sleeve 16 adsorbs the release paper adhered to the lower surface of the carbon fiber prepreg, and the release paper on the lower surface of the carbon fiber prepreg is separated as the outer sleeve 16 rotates, so as to facilitate the subsequent laying of the carbon fiber prepreg and improve the laying efficiency;

[0063] The connecting joint 19 is connected to the negative pressure pump, and air is sucked through the first suction hole 17 and the second suction hole 18. When the outer sleeve 16 rotates, the release paper is adsorbed and fixed through the second suction hole 18, and the release paper can be wound, so that the release paper is adsorbed and separated, thereby improving the convenience of separating the release paper;

[0064] When the adsorption plate 10 is moved to a certain position by means of the electric slider 7, the adsorption plate 10 is no longer in contact with the outer sleeve 16, and the support block 12 is driven to reset and move upward by means of the reset effect of the support spring 14, and then the release paper needs to be manually pulled away from the outer sleeve 16;

[0065] When the adsorption plate 10 has finished laying the carbon fiber prepreg, the electric slider 7 is used to reset the adsorption plate 10. When the adsorption plate 10 is reset, the lower edge of one side of the adsorption plate 10 is squeezed and contacted with the wedge-shaped guide block 20 again. As the adsorption plate 10 is reset to the initial state, it is convenient to move and lay the next group of carbon fiber prepreg.

[0066] In order to improve the viscosity of the carbon fiber prepreg, exemplary, such as Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, the present invention also includes that the rolling structure includes symmetrically arranged sliding grooves 23, the sliding grooves 23 are located on both sides of the support table 1, the sliding grooves 23 are slidably connected with sliding blocks 24, the upper surfaces of the sliding blocks 24 are fixedly connected with vertically arranged elastic rods 25, and a heating roller 26 is rotatably connected between the two groups of the elastic rods 25, and the heating roller 26 is in extrusion contact with the upper surface of the workbench 2, and the electric slider 7 is fixedly connected with a fixed rod 27 on one side close to the sliding block 24, and one end of the fixed rod 27 is fixedly connected to one side of the sliding block 24;

[0067] A pressing structure is provided on one side of the workbench 2, and the pressing structure is used to control the connection between the adsorption plate 10 and the negative pressure pump.

[0068] When in use, after the adsorption plate 10 has finished adsorbing the carbon fiber prepreg, the electric slider 7 moves to drive the fixed rod 27 to move, and the fixed rod 27 moves to drive the sliding block 24 and the heating roller 26 to move synchronously. When the sliding block 24 moves, it is slidably connected with the sliding groove 23. When the adsorption plate 10 moves to the top of the workbench 2, the electric telescopic rod 8 drives the adsorption plate 10 to move down. After the adsorption plate 10 moves down to a certain position, the adsorption plate 10 contacts the upper surface of the workbench 2, and at the same time squeezes and opens the pressing structure, and relies on the pressing structure to close the connection between the adsorption plate 10 and the negative pressure pump. At this time, the adsorption plate 10 no longer adsorbs the carbon fiber prepreg, and the carbon fiber prepreg is placed on the upper surface of the workbench 2.

[0069] After the carbon fiber prepreg is placed on the upper surface of the workbench 2, the adsorption plate 10 is driven to reset and move by the electric slider 7. When the electric slider 7 moves, it drives the sliding block 24 to move synchronously by the fixed rod 27. When the sliding block 24 resets and moves, it drives the elastic rod 25 and the heating roller 26 to reset and move synchronously. When the heating roller 26 moves to a certain position, the heating roller 26 rolls with the upper surface of the carbon fiber prepreg placed on the upper surface of the workbench 2. The heating roller 26 improves the viscosity of the carbon fiber prepreg. At the same time, the elastic rod 25 can improve the use stability of the heating roller 26, and at the same time, the heating roller 26 can adapt to carbon fiber prepregs of different thicknesses, further improving the convenience of laying the carbon fiber prepregs.

[0070] In order to lay the carbon fiber prepreg on the workbench 2, for example, Figure 1 As shown, the present invention also includes that the pressing structure includes a pressing switch 28, the pressing switch 28 is located on one side of the workbench 2, the pressing switch 28 is fixedly connected to the upper surface of the support table 1, and a pressing plate 29 is provided on the side of the adsorption plate 10 away from the electric telescopic rod 8. After the adsorption plate 10 moves to the top of the workbench 2, the pressing plate 29 corresponds to the pressing switch 28.

[0071] When in use, after the electric slider 7 drives the adsorption plate 10 to move above the workbench 2, the electric telescopic rod 8 drives the adsorption plate 10 to move downward. After the adsorption plate 10 moves downward to a certain position, the adsorption plate 10 contacts the upper surface of the workbench 2, and at the same time, the pressing plate 29 on one side of the adsorption plate 10 contacts the pressing switch 28 by compression, thereby closing the connection between the adsorption plate 10 and the negative pressure pump, and at the same time, the carbon fiber prepreg is laid on the workbench 2;

[0072] After the carbon fiber prepreg is laid, the electric telescopic rod 8 drives the adsorption plate 10 to move upward. After the adsorption plate 10 moves upward, the pressing plate 29 is no longer in contact with the pressing switch 28. At this time, the adsorption plate 10 is connected to the negative pressure pump again, and moves with the reset of the electric slider 7, so that the adsorption plate 10 can be used to adsorb the next group of carbon fiber prepreg again and lay multiple layers, so as to improve the convenience of use.

[0073] It should be pointed out that the press switch 28 should adopt a delay switch to ensure that the carbon fiber prepreg will not be adsorbed onto the adsorption plate 10 again after being detached from the adsorption plate 10; and the reset time of the delay switch should be less than the time it takes for the electric slider 7 to drive the adsorption plate 10 to reset from above the workbench 2 to above the slot 3.

[0074] For example, Figure 1 As shown, the present invention also includes that the lower surface of the support platform 1 is provided with a plurality of groups of vertically arranged support legs 30 , and reinforcing rods 31 are fixedly connected between adjacent support legs 30 .

[0075] When in use, the overall stability of the support platform 1 can be improved by relying on a plurality of groups of support legs 30 and reinforcing rods 31 .

[0076] An automated layer laying process for carbon fiber composite material prepreg, using the automated layer laying equipment for carbon fiber composite material prepreg, specifically comprises the following steps:

[0077] Step 1: laying a plurality of groups of carbon fiber prepregs in a storage structure;

[0078] Step 2: The carbon fiber prepreg in the storage structure is adsorbed by the adsorption moving structure, and the carbon fiber prepreg is driven to move toward the workbench 2;

[0079] Step 3: When the adsorption moving structure moves the carbon fiber prepreg onto the negative pressure structure, the negative pressure structure separates the release paper on the lower surface of the carbon fiber prepreg from the carbon fiber prepreg;

[0080] Step 4: The adsorption moving structure places the carbon fiber prepreg separated from the release paper on the workbench 2;

[0081] Step 5: While the adsorption structure is reset to the storage structure, the rolling structure moves to roll the prepreg on the workbench 2 to complete the laying of a layer of carbon fiber prepreg;

[0082] Step 6: Repeat steps 1 to 5 until the number of prepreg plies reaches the target requirement.

[0083] When the present invention is in use, when it is necessary to lay the carbon fiber prepreg, after placing several groups of carbon fiber prepreg on the movable plate 4, the adsorption plate 10 is connected to the negative pressure pump, and the adsorption plate 10 is driven downward by the electric telescopic rod 8. After the adsorption plate 10 moves down to a certain position, the lower surface of the adsorption plate 10 is squeezed and contacted with the carbon fiber prepreg stored on the movable plate 4, and the opening 11 of the adsorption plate 10 is adsorbed by the negative pressure pump. After the adsorption is completed, the adsorption plate 10 is driven upward again by the electric telescopic rod 8, and the electric slider 7 slides in the slide groove 6 to drive the electric telescopic rod 8 and the adsorption plate 10 to move, so as to facilitate the subsequent laying of the carbon fiber prepreg;

[0084] When the adsorption plate 10 moves to a certain position, the lower edge of one side of the adsorption plate 10 is squeezed and contacted with the wedge-shaped guide block 20, and as the adsorption plate 10 moves and squeezes, the support block 12 is driven to move downward. When the support block 12 moves downward, the support spring 14 is squeezed to store force; as the adsorption plate 10 continues to move, the card slot 22 provided on the lower surface of the adsorption plate 10 corresponds to the friction wheel 21, and at the same time, the friction wheel 21 is frictionally transmitted with the friction transmission plate installed in the card slot 22, thereby driving the friction wheel 21 to rotate. At this time, the carbon fiber prepreg adsorbed on the lower surface of the adsorption plate 10 is squeezed and contacted with the outer side of the outer sleeve 16, and the negative pressure pump is connected by the connecting joint 19. When the friction wheel 21 rotates, it drives the outer sleeve 16 to rotate. When the outer sleeve 16 rotates, the second suction hole 18 provided on the outer side of the outer sleeve 16 adsorbs the release paper adhered to the lower surface of the carbon fiber prepreg, and the release paper on the lower surface of the carbon fiber prepreg is separated as the outer sleeve 16 rotates, so as to facilitate the subsequent laying of the carbon fiber prepreg and improve the laying efficiency;

[0085] When the adsorption plate 10 is moved to a certain position by means of the electric slider 7, the adsorption plate 10 is no longer in contact with the outer sleeve 16, and the support block 12 is driven to reset and move upward by means of the reset effect of the support spring 14, and then the release paper needs to be manually pulled away from the outer sleeve 16;

[0086] When the adsorption plate 10 moves to the top of the workbench 2, the electric telescopic rod 8 drives the adsorption plate 10 to move down. After the adsorption plate 10 moves down to a certain position, the adsorption plate 10 contacts the upper surface of the workbench 2, and at the same time, the pressing plate 29 on one side of the adsorption plate 10 contacts the pressing switch 28, thereby closing the connection between the adsorption plate 10 and the negative pressure pump, and laying the carbon fiber prepreg on the workbench 2 at the same time;

[0087] After the carbon fiber prepreg is placed on the upper surface of the workbench 2, the adsorption plate 10 is driven to reset and move by the electric slider 7. When the electric slider 7 moves, it drives the sliding block 24 to move synchronously by the fixed rod 27. When the sliding block 24 resets and moves, it drives the elastic rod 25 and the heating roller 26 to reset and move synchronously; when the heating roller 26 moves to a certain position, the heating roller 26 rolls with the upper surface of the carbon fiber prepreg placed on the upper surface of the workbench 2, and the viscosity of the carbon fiber prepreg is improved by the heating roller 26. At the same time, the use stability of the heating roller 26 can be improved by the action of the elastic rod 25, and at the same time, the heating roller 26 can be adapted to carbon fiber prepregs of different thicknesses, further improving the convenience of plying the carbon fiber prepreg;

[0088] The adsorption plate 10 is driven to reset and move by the reset movement of the electric slider 7. When the adsorption plate 10 resets and moves, the lower edge of one side of the adsorption plate 10 is squeezed and contacted with the wedge-shaped guide block 20 again. As the adsorption plate 10 resets and moves to the initial state, this reciprocating movement facilitates the multi-layer laying of the carbon fiber prepreg. At the same time, there is no need to manually separate the release paper of the carbon fiber prepreg, thereby improving the laying efficiency and convenience of the laying.
