As an efficient and low-cost composite material forming process, vacuum-assisted resin infusion forming has been widely used in the manufacture of large-size and complex-structure composite material parts. The composite material plate formed by the vacuum-assisted resin infusion forming process usually needs to be demolded to remove the flow guide net and demolding cloth attached to the composite material plate. However, the manual demolding efficiency is low and the surface quality of the composite material plate after manual demolding is poor. SUMMARY

[0069] Composite materials are widely used in aerospace, automotive, marine, wind power and other fields due to their excellent mechanical properties, lightweight characteristics and corrosion resistance. Vacuum assisted resin infusion (VARI) is a high-efficiency and low-cost composite material forming process, which has been widely used in the manufacture of large-size and complex-structure composite material parts. VARI process injects resin into the reinforcing material (such as glass fiber or carbon fiber) pre-arranged in the mold through vacuum assistance, realizes the full infiltration of resin and reinforcing material, and forms high-performance composite material products after curing. The composite material plate formed by VARI process usually needs to be demolded. The demolded composite material plate is usually a multi-layer structure, the outer layer is a flow guide net, the middle layer is a demolding cloth, and the inner layer is a composite material plate (such as carbon fiber composite material plate, glass fiber composite material plate and basalt fiber composite material plate, etc.). Each layer and the layers are bonded by thermosetting plastic or thermoplastic plastic, and the composite material plate usually needs to be separated from the demolding cloth and the flow guide net.

[0070] In the VARI process, the demolding process is one of the important links that affect the quality and production efficiency of the final product. Especially after high-viscosity resin infusion, the demolding difficulty is significantly improved, which is specifically manifested in that ①the resin and fiber combination effect is good, it is difficult to remove the flow guide net from the composite material plate, and the traditional manual demolding cannot be moved at any time according to the demolding progress, thereby causing the demolding process to be discontinuous; ②the bottom of the traditional lever structure is too rough, which often damages the composite material plate; ③the traditional demolding process lacks local compression of the demolding part, which causes the demolding force to be unstable and easily damages the composite material plate.

[0071] In related technologies, the demolding workbench includes a fixed table and a pry knife. The fixed table has a fixed table surface for placing the first plate layer (demolding cloth and flow guide net) and the second plate layer (composite material plate). At least part of the pry knife is adapted to be inserted between the first plate layer and the second plate layer to pry open the first plate layer and the second plate layer, and then the pry knife is used to demold the formed composite material plate. However, this method usually relies too much on manual operation, the demolding time is long and the efficiency is low, and the demolding force applied to the pry knife is uneven due to the difference in operation, which further causes the surface of the composite material plate to be scratched, deformed or damaged.

[0072] In view of this, the present application provides a vacuum assisted resin infusion material plate demolding workbench, which includes a moving part, the moving part includes a moving part body and a first moving wheel connected to the moving part body, and a pry knife connected to the moving part body, so that the pry knife moves under the driving of the moving part. During the demolding process, the position of the pry knife inserted into the first plate layer and the second plate layer changes with the demolding process, which improves the quality and efficiency of demolding.

[0073] The first plate layer disclosed by the embodiment of the present application comprises a release cloth, a flow guide net and other accessory layers.

[0074] The second plate layer disclosed by the embodiment of the present application comprises a composite material plate.

[0075] The demolding disclosed by the embodiment of the present application refers to separating the first plate layer and the second plate layer.

[0076] The second plate layer disclosed by the embodiment of the present application is a flat plate.

[0077] The material of the second plate layer disclosed by the embodiment of the present application comprises a fiber composite material, the fiber composite material contains one or more of carbon fiber, glass fiber or basalt fiber, and the matrix material of the fiber composite material is thermosetting plastic or thermoplastic plastic.

[0078] The forming process of the composite material plate disclosed by the embodiment of the present application can be a vacuum-assisted resin infusion forming process and a hot press tank forming process.

[0079] The following embodiments are described by taking a vacuum-assisted resin infusion forming material plate demolding workbench of one embodiment of the present application as an example for convenience of description.

[0080] Please refer to Figures 1 to 3 , Figure 1 for the structural schematic diagram of the demolding workbench 100 provided by the embodiment of the present application; Figure 2 for Figure 1 the top view; Figure 3 for Figure 1 the side view.

[0081] In the embodiment, the demolding workbench 100 is used to separate the stacked first plate layer 10 and second plate layer 20, the demolding workbench 100 comprises a fixed table 30, a moving part 40 and a pry knife 50, the fixed table 30 has a fixed table surface for placing the first plate layer 10 and the second plate layer 20, the moving part 40 comprises a moving part body 41 and a first moving wheel 42 connected to the moving part body 41, at least part of the pry knife 50 is adapted to be inserted between the first plate layer 10 and the second plate layer 20, the pry knife 50 is connected to the moving part body 41, so that the pry knife 50 moves under the driving of the moving part 40.

[0082] Specifically, the shaped composite material plate which needs to be demolded is placed on the fixing table surface of the fixing table 30, generally, the shaped composite material plate includes the first plate layer 10 (the layer to be demolded) and the second plate layer 20 (the composite material plate layer), the second plate layer 20 is in contact with the fixing table surface of the fixing table 30, at the beginning of demolding, at least part of the pry knife 50 is inserted between the first plate layer 10 and the second plate layer 20 at a suitable angle and position, so that the first plate layer 10 and the second plate layer 20 are separated, then the pry knife 50 is pushed into the first plate layer 10 and the second plate layer 20 by the moving part 40 connected with the pry knife 50, until the first plate layer 10 and the second plate layer 20 are completely separated, at this time, the demolding is successful.

[0083] Because the first moving wheel 42 is arranged on the moving part 40, during the movement of the pry knife 50 driven by the moving part 40, the first moving wheel 42 on the moving part 40 is in contact with the second plate layer 20, without the moving part body 41 and the second plate layer 20 being in contact, so that the friction between the moving part 40 and the second plate layer 20 is changed from sliding friction to rolling friction, the friction coefficient is reduced, the friction resistance between the first moving part 40 and the second plate layer 20 is reduced, so that the worker can separate the first plate layer 10 and the second plate layer 20 with smaller force, the demolding work efficiency is improved, and the demolding time is saved. Moreover, because the friction between the first moving part 40 and the second plate layer 20 is reduced, the probability of damage to the second plate layer 20 is reduced, and the demolding quality of the second plate layer 20 is improved.

[0084] It should be noted that because the first moving wheel 42 is arranged on the moving part 40, the moving part body 41 is connected with the pry knife 50, and the moving part body 41 is fixedly connected with the pry knife 50, so that the pry knife 50 can be inserted between the first plate layer 10 and the second plate layer 20 at a fixed angle and direction, which is beneficial to the worker to insert the pry knife 50 between the first plate layer 10 and the second plate layer 20 at a fixed angle and direction during the demolding process, and the pry knife 50 can demold the first plate layer 10 and the second plate layer 20 along the preset angle and direction (which can be adjusted by the worker according to the actual situation of demolding) during the demolding process, so that the demolding process is more standardized and efficient, which is beneficial to maintaining the consistency of the demolding product and improving the quality of the demolding product.

[0085] In some embodiments, the part of the pry bar 50 inserted between the first plate layer 10 and the second plate layer 20 can be the sharp part of the pry bar 50. Since there is usually a large adhesion between the first plate layer 10 and the second plate layer 20, the pry bar 50 needs to overcome the adhesion between the first plate layer 10 and the second plate layer 20 during demolding to separate the first plate layer 10 and the second plate layer 20. The sharp part of the pry bar 50 is inserted into the first plate layer 10 and the second plate layer 20. Under the same force applied by the worker, the contact area (force receiving area in the insertion direction) of the sharp part with the first plate layer 10 and the second plate layer 20 is smaller, so the worker can more easily separate the first plate layer 10 and the second plate layer 20. For example, the sharp part of the pry bar 50 can be made of high-strength hard wear-resistant material.

[0086] In some embodiments, the pry bar 50 as a whole can be made of high-strength alloy steel, and the surface near the sharp part of the pry bar 50 can be coated with rubber or other cushioning materials to reduce the occurrence of excessive wear of the surface of the second plate layer 20.

[0087] In some embodiments, the number of first moving wheels 42 can be one, two or more, and the number of first moving wheels 42 is not specifically limited in the embodiments of the present application. For example, the first moving wheel 42 can be made of wear-resistant soft rubber material with a Shore hardness of 60 to 70, and the surface of the first moving wheel 42 can be designed with small grooves to appropriately increase the friction with the second plate layer 20, thereby improving the surface quality of the second plate layer 20 after demolding.

[0088] In some embodiments, since the formed composite material plate will be warped, a plurality of fixing plates 70 can also be provided on the fixed table. When the demolding workbench 100 is used to separate the second plate layer 20 and the first plate layer 10, the plurality of fixing plates 70 are pressed on the edge of the first plate layer 10 away from the end of the pry bar 50 inserted into the first plate layer 10 and the second plate layer 20. In this way, the first plate layer 10 is fixed by the fixing plate 70, and then the pry bar 50 is used to separate the first plate layer 10 and the second plate layer 20. On the one hand, it can prevent the cut plate layer from moving or mispositioning when the pry bar 50 cuts the first plate layer 10 and the second plate layer 20, which helps to improve the flatness and precision of the cutting surface. On the other hand, fixing the edge of the first plate layer 10 away from the pry bar 50 can also reduce the cutting deviation caused by vibration or external force interference. Through stable support and fixation, the accuracy and consistency of the cutting path can be ensured, which is beneficial to guarantee the quality of the demolding product. It should be noted that the side of the fixing plate 70 in contact with the first plate layer 10 can be coated with a 1mm rubber layer or other cushioning layer to protect the surface of the second plate layer 20 and reduce the probability of surface damage of the second plate layer 20.

[0089] In some embodiments, a plurality of adjusting holes 80 can be arranged on the fixing table 30, the diameter of the adjusting holes 80 can be set as 20mm, the adjusting holes 80 can be used to install the fixing plates 70, by arranging the fixing plates 70 on the adjusting holes 80, the fixing plates 70 can be used to adaptively fix the first plate layer 10 and the second plate layer 20 according to the size and shape of the first plate layer 10 and the second plate layer 20. For example, the adjusting holes 80 and the fixing plates 70 can be used to fix the position of the first plate layer 10 and the second plate layer 20 through the bolt structure, when the first plate layer 10 and the second plate layer 20 need to be fixed, the bolt is loosened, so that the first plate layer 10 and the second plate layer 20 are embedded below the fixing plates 70, then the bolt is tightened, so as to fix the first plate layer 10 and the second plate layer 20. By arranging the adjusting holes 80 on the fixing table 30, the fixing table 30 can be used to fix the first plate layer 10 and the second plate layer 20 with different sizes and sizes, for example, the fixing table 30 can be used to adapt to the rectangular first plate layer 10 and the second plate layer 20 with the size of 2000mm*2000mm to 200mm*200mm.

[0090] In some embodiments, the sharp part of the pry knife 50 can be arranged as a blade, the pry knife 50 can be divided into an upper part and a lower part, the blade of the pry knife 50 is arranged between the upper part and the lower part, the upper part and the lower part are pressed tightly through the screw, so that the blade is fixed tightly between the upper part and the lower part of the pry knife 50, the probability of damage of the pry knife 50 and the probability of damaging or scratching the second plate layer 20 in the demolding process are reduced, and the demolding quality and efficiency are improved.

[0091] Please refer to Figures 4 to 9 , Figure 4 the structure view of the moving part 40 and the pry knife 50 provided by the embodiments of the present application; Figure 5 is Figure 4 the bottom view; Figure 6 is Figure 4 the side view; Figure 7 is Figure 5 the exploded structure view; Figure 8 is Figure 7 the side view; Figure 9 is the structure schematic view of the first moving wheel 42 and the locking part 46.

[0092] In the embodiment, the first moving wheel 42 is an omni-directional wheel. In this way, the moving part 40 has the ability of multi-directional movement, and can move forward and backward, left and right, and even combine the movements in these directions to form a resultant force movement. This feature enables the moving part 40 to move flexibly at any angle on the second board layer 20, and further enables the position and cutting direction of the pry knife 50 to be adjusted arbitrarily according to the actual situation of demolding, so that the cutting direction of the pry knife 50 can be adjusted at any time according to the actual situation of demolding, and the use convenience is improved, and the demolding quality is facilitated to be ensured.

[0093] It should be noted that the omni-directional wheel can be made of wear-resistant soft rubber material with a Shore hardness of 60 to 70, and the surface of the first moving wheel 42 can be designed as micro grooves to appropriately increase the friction with the second board layer 20, and further improve the surface quality of the second board layer 20 after demolding.

[0094] Please refer again to Figures 4 to 9 In the embodiment, the moving part body includes a first top wall 43, and further includes a support plate 44 protruding from the upper surface of the first top wall 43. The pry knife 50 includes a knife body 51 and a knife handle 52 connected with the knife body 51, and the knife handle 52 is in abutment with the upper end of the support plate 44.

[0095] During the demolding process, the worker can control the moving direction and position of the moving part body through the first top wall 43, and abut the knife handle 52 with the upper end of the support plate 44. When the pry knife 50 is inserted between the first board layer 10 and the second board layer 20, the pry knife 50 forms a lever structure by means of the support plate 44, which plays a labor-saving role and is conducive to the worker to separate the first board layer 10 and the second board layer 20, and improves the demolding efficiency. Moreover, since the knife handle 52 and the upper end of the support plate 44 are in abutment, the movement of the moving part body 41 will also drive the pry knife 50 to move. In this way, only the position and direction of the moving part body 41 need to be controlled, and the position and direction of the pry knife 50 can be controlled, and then the first board layer 10 and the second board layer 20 can be separated, so that the demolding process is easier to perform. Abutting the upper end of the knife handle 52 and the support plate 44 can also fix the pry knife 50 and the moving part 40, so that the pry knife 50 is inserted into the first board layer 10 and the second board layer 20 at a fixed angle. During the demolding process, the first board layer 10 and the second board layer 20 can also be separated at a constant angle, and the demolding quality is ensured.

[0096] In some embodiments, the knife handle 52 of the pry knife 50 and the upper end of the support plate 44 are in abutment, which facilitates the worker to adjust the position and angle of the abutment between the pry knife 50 and the moving part body 41 at any time, so that the pry knife 50 and the moving part 40 can be adaptively adjusted according to the actual demolding situation to cope with the complex and changeable demolding production environment, and the demolding quality is improved.

[0097] Please refer to Figures 4 to 9 In the embodiment, the moving part body further comprises a first peripheral wall 45 formed on the outer periphery of the first top wall 43 and extending downward, and the first moving wheel 42 is rotatably arranged on the first peripheral wall 45. The moving part 40 further comprises a locking member 46 arranged on the first peripheral wall 45 and selectively locking the first moving wheel 42.

[0098] The first peripheral wall 45 is formed on the outer periphery of the first top wall 43 and extends downward, so that the worker can more fully contact the moving part 40 when demolding the formed composite material plate, facilitating the worker to control the movement of the moving part 40 and the pry knife 50, and improving the demolding efficiency. At the beginning of demolding, the locking member 46 arranged on the first peripheral wall 45 limits the movement of the moving part 40 to prevent the moving part 40 from moving in the opposite direction of the insertion of the pry knife 50 into the first plate layer 10 and the second plate layer 20 during the insertion of the pry knife 50 into the first plate layer 10 and the second plate layer 20 at the beginning of demolding, resulting in a decrease in the demolding force of the pry knife 50 inserted between the first plate layer 10 and the second plate layer 20. By limiting the movement of the moving part 40 by the locking member 46, the demolding force is greater, and the demolding efficiency is improved. For example, a groove can be provided on the first peripheral wall 45, one end of the locking member 46 is provided with a protrusion, and the other end of the locking member 46 is connected to the first moving wheel 42. When it is necessary to limit the movement of the moving part 40, the locking member 46 is inserted into the first peripheral wall 45 and the first moving wheel 42 to limit the rotation of the first moving wheel 42. When it is not necessary to limit the movement of the moving part 40, the protruding part of the locking member 46 can be separated from the groove part of the first peripheral wall 45, so that the first moving wheel 42 can rotate.

[0099] Please refer to Figures 4 to 9 In the embodiment, the demolding workbench 100 further comprises a pressing plate 60 installed on the moving part 40 and adapted to press the second plate layer 20.

[0100] During the demolding process using the demolding workbench 100, the pressing plate 60 can be arranged at a position in front of the moving part 40 and behind the pry knife 50 in the demolding direction. Since the first plate layer 10 and the second plate layer 20 have a certain bonding force during the demolding process, the process of separating the first plate layer 10 and the second plate layer 20 by the pry knife 50 can cause the second plate layer 20 to locally bulge, thereby reducing the demolding force and affecting the demolding quality. By pressing the second plate layer 20 with the pressing plate 60, the demolding force is increased, the demolding efficiency is improved, and the probability of local bulging of the second plate layer 20 is reduced, thereby improving the demolding quality and making the demolding process more stable.

[0101] In some embodiments, the shape of the pressing plate 60 can be rectangular, circular or long concave. When the pressing plate 60 is rectangular, the contact area between the pressing plate 60 and the second plate layer 20 can be increased, and more parts of the second plate layer 20 can be pressed, so as to effectively improve the demolding quality. When the pressing plate 60 is circular, on one hand, the pressing plate 60 can be in full contact with the second plate layer 20, so as to press the second plate layer 20 and reduce the probability of local bulging of the second plate layer 20; on the other hand, since the edge of the circular pressing plate 60 is smooth and has no sharp and sharp parts, the local bulging of the second plate layer 20 can be prevented from directly contacting the edge of the circular pressing plate 60, so as to reduce the possibility of damage of the second plate layer 20 caused by scratching and improve the demolding quality. When the shape of the pressing plate 60 is long concave, the contact area between the long concave shape and the second pressing plate 60 is reduced, so as to reduce the friction area between the pressing plate 60 and the second plate layer 20, and further reduce the probability of damage of the second plate layer 20 caused by scratching.

[0102] In some embodiments, the side of the pressing plate 60 in contact with the second plate layer 20 is covered with a 1mm-thick or multi-layer rubber buffer material or other buffer material, so as to reduce the probability of damage of the second plate layer 20 caused by the pressing plate 60.

[0103] Please refer to Figures 4 to 9 In the embodiment, the outer circumferential surface of the moving part 40 is provided with a mounting part 47 having a plug-in slot 474 open downward, and the pressing plate 60 is provided with a plug-in plate 61 extending upward, which is selectively plugged into the plug-in slot 474.

[0104] By using the plug-in cooperation of the plug-in plate 61 and the plug-in slot 474, the moving part 40 and the pressing plate 60 can be connected by a simple plug-in action without the need for complex screw fixing or other fasteners, so as to greatly speed up the installation and disassembly and improve the work efficiency. By using the plug-in cooperation of the plug-in plate 61 and the plug-in slot 474, the overall structure of the moving part 40 and the pressing plate 60 can be simplified, the number and complexity of parts can be reduced, and the difficulty and cost of design and manufacturing can be reduced. Moreover, by controlling the plug-in depth of the plug-in plate 61 and the plug-in slot 474, the relative displacement of the pressing plate 60 and the moving part 40 in the vertical direction can be controlled, the pressing force of the pressing plate 60 on the second plate layer 20 can be adjusted, and the pressing degree between the pressing plate 60 and the second plate layer 20 can be adjusted according to the actual demolding condition, so that the pressing between the pressing plate 60 and the second plate layer 20 is more adaptive, and the probability of scratching of the second plate layer 20 is reduced.

[0105] Please refer to Figures 4 to 9In the embodiment, the mounting portion 47 comprises a second bottom wall 471 and a second peripheral wall 472 formed on the outer periphery of the second bottom wall 471 and extending downward, and the second peripheral wall 472 is provided with an opening portion 473. The mounting portion 47 further comprises an eccentric wheel 475 rotatable relative to the second peripheral wall 472, and a portion of the eccentric wheel 475 passes through the opening portion 473 to selectively press the plug-in plate 61 against the inner peripheral wall of the plug-in groove 474.

[0106] When it is required to fix the plug-in plate 61 and the plug-in groove 474, the eccentric wheel 475 can be rotated to fasten the plug-in plate 61 and the plug-in groove 474 at a fixed position, so that the moving portion 40 and the pressing plate 60 are in a relatively static state. During the movement of the moving portion 40, the pressing plate 60 can be moved. By connecting and fixing the moving portion 40 and the pressing plate 60 through the rotation of the eccentric wheel 475, the moving portion 40 and the pressing plate 60 can be fixed by adjusting the rotation angle of the eccentric wheel 475, without the need for complex operation steps or equipment, thereby improving the demolding efficiency.

[0107] In some embodiments, the opening portion 473 of the second peripheral wall 472 can be a square hole or a circular hole, and the shape of the opening portion 473 is not limited in the present application.

[0108] Please refer to Figures 4 to 9 In the embodiment, the mounting portion 47 further comprises a mounting ring 476 surrounding the outer periphery of the second peripheral wall 472 and fixedly connected with the second peripheral wall 472, and the eccentric wheel 475 is rotatably arranged on the mounting ring 476.

[0109] By arranging the mounting ring 476 on the outer periphery of the second peripheral wall 472 and rotatably arranging the eccentric wheel 475 on the mounting ring 476, on the one hand, the mounting ring 476 can provide a rotation axis for the eccentric wheel 475, so that the eccentric wheel 475 can rotate smoothly on the mounting ring 476, and on the other hand, by rotatably arranging the eccentric wheel 475 on the mounting ring 476, the local pressure of the mounting portion 47 can be dispersed, so that the single-point stress condition is avoided, and the service life of the mounting portion 47 is improved.

[0110] Please refer to Figures 4 to 9 In the embodiment, the mounting portion 47 further comprises a pressing block 477 arranged between the eccentric wheel 475 and the plug-in plate 61, and the pressing block 477 comprises a first arc surface abutting against the eccentric wheel 475 and a first flat surface abutting against the plug-in plate 61.

[0111] The pressing block 477 is arranged between the eccentric wheel 475 and the plug-in plate 61, so that the pressing block 477 is fastened with the plug-in plate 61 by the eccentric wheel 475, and the moving part 40 is fixedly connected with the pressing plate 60. When it is needed to fix the moving part 40 and the pressing plate 60, the eccentric wheel 475 is rotated to increase the force between the eccentric wheel 475 and the pressing block 477, and then the force between the pressing block 477 and the plug-in plate 61 is increased, so that the pressing plate is limited to slide up and down, and then the local pressing force is applied downward. Moreover, the pressing block 477 is arranged between the eccentric wheel 475 and the plug-in plate 61, so that the direct contact between the eccentric wheel 475 and the plug-in plate 61 is effectively avoided, the single-point force condition is avoided, the reliability and stability of the plug-in plate 61 are improved, and the demolding quality and efficiency are improved.

[0112] Please refer to Figures 4 to 9 In the embodiment, the pry knife 50 is provided with the second moving wheel 53 in contact with the fixed table top.

[0113] By arranging the second moving wheel 53 in contact with the fixed table top on the pry knife 50, the position of the pry knife 50 can follow the movement of the demolding position during the demolding process, the friction between the pry knife 50 and the second plate layer 20 is reduced, the probability of damage or injury of the second plate layer 20 is reduced, the demolding quality of the second plate layer 20 is improved, and the demolding efficiency is improved.
