Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold stripping, in particular to an intelligent stripping device for a composite material forming mold. BACKGROUND

[0002] In the field of composite material manufacturing, the stripping process as a key link in the forming process directly affects the performance and cost of the final product. Traditionally, the stripping of composite materials mainly relies on manual operation or simple mechanical devices. These methods generally face the problems of insufficient universality, low operation efficiency, and uneven stress on the material during the stripping process when dealing with different shapes, sizes, and complex structures of composite materials. In the prior art, the stripping of composite materials is mainly achieved by fixed molds combined with ejection mechanisms or manual operation using tools. Although the fixed mold ejection mechanism can achieve a certain degree of automation, it is often designed for specific shapes and sizes of composite materials, lacking flexibility and being difficult to adapt to multi-variety and small-batch production requirements. Manual stripping using tools completely relies on the experience and skills of the operator, which not only has high labor intensity, but also cannot guarantee the consistency of stress on each part of the composite material during stripping, which easily leads to material deformation, cracking, or even scrap, seriously affecting production efficiency and product quality. Especially critical is that the adhesion between the composite material and the mold during the stripping process is often uneven, which is mainly caused by uneven application of release agent, differences in mold surface gloss, or uneven heat release during local resin curing. When this uneven adhesion exists, if the traditional method is still used for stripping, it is likely to cause local stress concentration of the composite material in the area with larger adhesion, which further leads to the generation and expansion of internal micro-cracks in the material, and even causes the destruction of the entire material structure, resulting in irreversible loss.

[0025] Step one, use time, will draw the air pump through the pipeline and pull the inner cavity of the barrel 811 top end connection, will air pump through the pipeline and extrusion groove 823 inner cavity connected, start the first infrared sensor 87, the second infrared sensor 88, the first receiver 89 and the second receiver 810, the first infrared sensor 87 emits infrared signal can penetrate the first monitoring hole 827 and the second monitoring hole 830 inner cavity irradiation to the first receiver 89, using the first receiver 89 receives the first infrared sensor 87 emits infrared signal, similarly, the second infrared sensor 88 emits infrared signal can penetrate the first monitoring hole 827 and the second monitoring hole 830 inner cavity irradiation to the second receiver 810, using the second receiver 810 receives the second infrared sensor 88 emits infrared signal, the mold containing composite material is placed in the inner cavity of the main frame 1 bottom end, start the first motor 5, using the output end of the first motor 5 drive positive and negative screw rod 6 rotation, the rotation force generated by the positive and negative screw rod 6 can drive two clamping plate 4 synchronous move to the inside, until the two clamping plate 4 clamp and fix the mold, according to the maximum tensile strength of composite material can start electric telescopic rod 832, using electric telescopic rod 832 push third piston 831 along the inner cavity of the second pressure regulating cylinder 826 downward movement, third piston 831 along the inner cavity of the second pressure regulating cylinder 826 downward movement can extrude the air between third piston 831 and monitoring block 829, so as to promote the air pressure between third piston 831 and monitoring block 829, until adjusted to the appropriate pressure, electric telescopic rod 832 is closed; Step two, the shape and size of the composite material in the mold is scanned by the visual sensor 86, the first hydraulic cylinder 83 is started, the support plate 81 is pushed down by the first hydraulic cylinder 83, the support plate 81 moves down to drive the pull cylinder 811, the third guide rod 82 and the second hydraulic cylinder 85 to move down, the third guide rod 82 and the second hydraulic cylinder 85 move down to drive the pressing plate 84 to move down, until the bottom end of the suction cup 815 corresponding to the position of the composite material contacts the composite material, the support plate 81 continues to drive the pull cylinder 811 to move down, the pull cylinder 811 continues to move down to push the first piston rod 813 in contact with the composite material to move upward along the inner cavity of the pull cylinder 811, and the suction cup 815 is pushed to drive the ball 814 to roll and rotate according to the shape of the composite material, so that the suction cup 815 can match the shape of the composite material, and then the suction cup 815 is firmly attached to the outer wall of the composite material, at the same time, when the first piston rod 813 drives the first piston 812 to move upward along the inner cavity of the pull cylinder 811, the inner cavity of the pull cylinder 811 is connected to the inner cavity of the first pressure regulating cylinder 816 through the pipeline, and then the second piston 817 is driven to move downward along the inner cavity of the first pressure regulating cylinder 816 under the action of air pressure, so that the second piston rod 818 moves downward along the inner cavity of the clamping block 822, and the second piston rod 818 drives the slide of the slide rheostat 820 to slide downward along the slide rheostat 820, when the second piston rod 818 drives the slide of the slide rheostat 820 to slide downward along the slide rheostat 820, it means that the suction cup 815 corresponding to the slide rheostat 820 has been firmly attached to the surface of the composite material, with the support plate 81 driving the pull cylinder 811 to move down, until the suction cup 815 corresponding to the position of the composite material shape contacts the composite material and is firmly attached to the surface thereof, the first hydraulic cylinder 83 is closed, and then the support plate 81 stops moving downward; Step three, air is transported into the inner cavity of the extrusion groove 823 through the air pump, and then the clamping block 825 is pushed to move inward under the action of air pressure, and the spring 824 is elastically deformed. The inward movement of the clamping block 825 can promote the clamping block 825 to be inserted into the inner cavity of the clamping groove 819 corresponding to its position. The second hydraulic cylinder 85 is started according to the maximum tensile force that the composite material can bear, the second hydraulic cylinder 85 is used to pull the pressing plate 84 to move downward, the pressing plate 84 moves downward to push the clamping block 822 to move downward through the supporting rod 821, so that the clamping block 822 moves downward to push the second piston rod 818 to drive the second piston 817 to move downward under the action of the clamping block 825 and the clamping groove 819. The second piston 817 slides downward along the inner cavity of the first pressure adjusting cylinder 816 to extrude the air between the bottom end of the second piston 817, the bottom end of the first piston 812 and the bottom end of the monitoring block 829, so as to increase the air pressure between the bottom end of the second piston 817, the bottom end of the first piston 812 and the bottom end of the monitoring block 829, until the air pressure is the same as the air pressure between the bottom end of the third piston 831 and the top end of the monitoring block 829, and the second hydraulic cylinder 85 is closed. Step four, start the suction pump connected with the inner cavity of the pull cylinder 811, the suction pump starts to extract the air in the inner cavity of the pull cylinder 811, the inner cavity of the first piston rod 813 and the inner cavity of the suction disc 815, so as to promote the suction disc 815 to be adsorbed on the surface of the composite material under the action of air pressure, start the first hydraulic cylinder 83, pull the support plate 81 up by the first hydraulic cylinder 83, so as to drive the pull cylinder 811 up by the support plate 81, the pull cylinder 811 moves up to drive the first piston rod 813 to move up, which can prevent the composite material from pulling the first piston rod 813 to move down along the inner cavity of the pull cylinder 811 under the action of air pressure between the bottom end of the second piston 817, the bottom end of the first piston 812 and the bottom end of the monitoring block 829, so as to pull the composite material to operate the mold under the action of the suction disc 815, the first piston rod 813 and the pull cylinder 811. When the adhesion between the composite material and the mold at different positions is different due to uneven application of release agent, difference in gloss of the mold surface, or excessive local resin curing heat release, etc., if the adhesion is too large, the suction disc 815 corresponding to the position will bear greater tension during the upward movement of the pull cylinder 811. If the tension exceeds the maximum tension that the composite material can bear, the first piston rod 813 will be pulled down under the action of the adhesion of the composite material, thereby further extruding the air between the bottom end of the second piston 817, the bottom end of the first piston 812 and the bottom end of the monitoring block 829, thereby further increasing the air pressure between the bottom end of the second piston 817, the bottom end of the first piston 812 and the bottom end of the monitoring block 829. Due to the increase of the air pressure at the position, the air pressure at the position will be greater than the air pressure between the bottom end of the third piston 831 and the top end of the monitoring block 829, thereby pushing the monitoring block 829 to move up along the inner cavity of the second pressure adjusting cylinder 826 under the action of air pressure. When the monitoring block 829 moves up along the inner cavity of the second pressure adjusting cylinder 826, the first monitoring hole 827 and the second monitoring hole 830 will be dislocated, thereby shielding the infrared signal emitted by the first infrared sensor 87 and the second infrared sensor 88 corresponding to the position, thereby preventing the first receiver 89 and the second receiver 810 corresponding to the first infrared sensor 87 and the second infrared sensor 88 from receiving the infrared signal, thereby transmitting to the control center, closing the first hydraulic cylinder 83, and detecting the position of the composite material with excessive adhesion according to the positioning coordinates of the first receiver 89 and the second receiver 810, and processing by workers, thereby preventing the composite material from being damaged due to excessive tension.
