DETAILED DESCRIPTION

[0050] Reference Figures 1 to 10 , the present invention provides a technical solution: a resin-based fiber material manufacturing device for unmanned vehicle protection, comprising: a base 1, a pressing mechanism 2, a feeder 4, a conveyor 5, and a control component 6;

[0051] The feeder 4, the conveyor 5, and the control component 6 are installed on the base 1; the control component 6 is used to debug the pressing execution parameters of the pressing mechanism 2 for the hat-shaped rib 3;

[0052] The pressing mechanism 2 is fixed on the base 1 and is used to press the hat-shaped rib 3. Specifically, the pressing mechanism 2 includes: a hydraulic drive platform, a drive assembly 8, and a side pressure assembly 9.

[0053] The hydraulic drive platform is fixed on the base 1 to provide driving force for the drive assembly 8; the drive assembly 8 is fixed on the hydraulic drive platform to drive the side pressure assembly 9;

[0054] The side pressure assembly 9 is installed on the driving assembly 8 and connected to the hydraulic driving platform. The side pressure assembly 9 is used to flatten, exhaust and press the hat-shaped ribs.

[0055] When the hat-shaped rib 3 begins to be pressed, the pressing force of the driving component 8 and the side pressure component 9 on the hat-shaped rib 3 and the feeding frequency of the feeder 4 and the conveyor 5 are first adjusted through the control component 6 .

[0056] After the parameter adjustment is completed, the hat-shaped rib 3 is transported to the hydraulic drive platform through the feeder 4, and the hydraulic drive platform will adjust the position of the hat-shaped rib 3 to facilitate the pressing operation thereof through the side pressing assembly 9 and the hydraulic drive platform.

[0057] After the pressing operation is completed, the hydraulic drive platform releases the limit on the hat-shaped rib 3 and transports it to the conveyor 5, and then it is transported to the placement room through the conveyor 5.

[0058] When the side pressure component 9 presses the hat-shaped rib 3, it first gradually increases its pressing force obliquely downward. During the oblique downward process, the side skin is pulled to gradually stretch the top skin of the hat-shaped rib 3 to both sides, thereby preventing the skin from wrinkling and unevenness after the pressing is completed, and improving its pressing flatness; at the same time, in the process of stretching the top skin to make it flat, the adhesive therein flows slowly, reducing the presence of bubbles therein, thereby achieving the effect of exhaust, that is, improving the bonding effect between the skins and avoiding the occurrence of local warping and peeling.

[0059] When the side pressure assembly 9 pulls the side of the hat-shaped rib 3, it will simultaneously flatten the side skin and squeeze the adhesive inside it, so as to maintain the pressing effect of the side skin, improve its pressing flatness and prevent the generation of bubble cavities.

[0060] As a preferred embodiment, the hydraulic drive platform includes:

[0061] A driving platform 21, one end of which is fixed on the base 1, and the other end of which is provided with a working table, on which two conveying guide platforms 26 are symmetrically provided, and the conveying guide platforms 26 are driven by a first motor to convey the hat-shaped ribs 3;

[0062] Two sliding posts 22, one end of which is symmetrically fixed on the work surface, and the other end of which is slidably provided with a top seat 25, on which an upper pressing plate 29 is fixed;

[0063] A hydraulic rod 23, one end of which is connected to the driving platform 21 and driven by the driving platform 21, and the other end of which is fixedly connected to the top seat 25;

[0064] A guide block 24 is arranged at the inlet of the work surface; a limit table 28 is rotatably arranged at the outlet of the work surface and driven by a second motor to position the hat-shaped rib 3 of the work surface;

[0065] There are four fixed guide pillars 27 , which are symmetrically arranged in pairs on the work surface and connected to the driving assembly 8 .

[0066] As a preferred embodiment, the fixed guide column 27 is penetrated by a limited position slide rail.

[0067] It should be noted that the feeder 4 transports the hat-shaped rib 3 after the skin is laid to the work surface, and the hat-shaped rib 3 is stopped in the pressing work area under the action of the guide block 24, the conveying guide platform 26 and the limit platform 28. After the hat-shaped rib 3 is parked, the hydraulic rod 23 moves the upper pressure plate 29 to press the top layer of the hat-shaped rib 3; at the same time, during the movement of the hydraulic rod 23, the driving component 8 drives the side pressure component 9 to synchronously press the side of the hat-shaped rib 3.

[0068] It should be noted that when the upper pressure plate 29 is pressed against the top skin of the hat-shaped rib 3, the side pressure assembly 9 has completed the flattening and exhausting operation of the top skin; when the top skin is pressed, the side skin is pressed synchronously, thereby achieving integrated synchronous pressing, improving the pressing efficiency while improving the skin bonding effect.

[0069] After the cap-shaped rib 3 is pressed, the limiting platform 28 releases the limitation on it, so that it is transferred to the conveyor 5 through the conveying guide platform 26.

[0070] As a preferred embodiment, the driving assembly 8 includes: a bearing rod 81, a mounting rod 82, a first rack 83, a first gear 84, and a limiting slide groove 85;

[0071] The bearing rod 81 is sleeved and fixed on the hydraulic rod 23, one end of the mounting rod 82 is fixed on the bearing rod 81, and the other end is rotatably provided with the first gear 84;

[0072] The first rack 83 is fixed on the slide post 22 and meshes with the first gear 84 ; the limiting slide groove 85 is provided on the mounting rod 82 and connected with the side pressure assembly 9 .

[0073] It needs to be explained that when the hydraulic rod 23 moves downward, the first gear 84 is synchronously moved downward through the mounting rod 82, and when the first gear 84 moves downward, the first gear 84 is rotated through the first rack 83, that is, the first gear 84 drives the side pressure assembly 9 to press the hat-shaped rib 3.

[0074] As a preferred embodiment, the side pressure assembly 9 includes:

[0075] Two second gears 91 are symmetrically rotatably arranged on the mounting rod 82, one end of which is coaxially connected to the first gear 84, and the other end is rotatably connected to one side of a slider 96. The slider 96 is slidably arranged in the limit slide rail, and a fixed shaft 93 is fixedly arranged on the other side of the slider 96;

[0076] A second rack 92 is slidably disposed in the limiting sliding groove 85 and meshes with the second gear 91. A push rod is also provided at the end of the second rack 92;

[0077] An adjustable telescopic rod 97, one end of which is fixed on the fixed shaft 93, and the other end of which is rotatably arranged on the side pressure plate 95;

[0078] There are two pressing adjustment blocks 94, one end of which is symmetrically fixed on the side pressure plate 95, and the other end is sleeved on the push rod.

[0079] As a preferred embodiment, a torsion spring is provided at the rotational connection between the adjustable telescopic rod 97 and the fixed shaft 93. The torsion spring keeps the side pressure plate 95 and the side of the hat-shaped rib 3 in a horizontal state when no pressing operation is performed, and provides a certain deflection margin during flattening and venting to prevent the structure from locking.

[0080] As a preferred embodiment, the pressing adjustment block 94 is connected to the push rod through an adjusting spring. By replacing different adjusting springs, the flattening, exhaust and pressing effects of the hat-shaped rib 3 skin can be adjusted relatively by adjusting the side pressure plate 95. The adjusting spring also allows a certain amount of activity to exist between the push rod and the pressing adjustment block 94, thereby preventing the structure from being locked.

[0081] It should be noted that when the first gear 84 rotates, the second gear 91 will rotate synchronously, that is, the second rack 92 will be driven to slide relative to the mounting rod 82 through the limiting slide groove 85. When the second rack 92 slides, the pressing adjustment block 94 is adjusted to adjust the contact pressure between the side pressure plate 95 and the side skin of the hat-shaped rib 3.

[0082] At the same time, the side pressure plate 95 is synchronously moved down by adjusting the slider 96 and the telescopic rod 97, so that the side pressure plate 95 completes the flattening and exhausting operation of the top layer of the hat-shaped rib 3 and the side skin, and completes the pressing operation after the flattening and exhausting of the skin.

[0083] A manufacturing process of a resin-based fiber material for unmanned vehicle protection, characterized in that it comprises: a reinforcing rib 10, a skin 11, and an industrial foam 12;

[0084] The industrial foam 12 is fixed to the reinforcing rib 10 by adhesive. From an economic point of view, when the hat-shaped rib is formed, the industrial foam filling method is adopted. The industrial foam can be used as a molding mold, which can greatly reduce the number of auxiliary molding molds and effectively reduce the cost of the product.

[0085] Structurally, industrial foam is used as the intermediate filling structure, which has the properties of transferring loads, improving stiffness, absorbing energy, and keeping warm.

[0086] The skin 11 is laid on the reinforcing ribs 10 through the industrial foam 12; the skin 11 and the reinforcing ribs 10 are integrally formed through secondary curing.

[0087] As a preferred embodiment, the skin 11 is composed of glass fiber and carbon fiber, and the glass fiber and carbon fiber are integrally pressed together by a pressing mechanism 2 .

[0088] As a preferred embodiment, the reinforcing rib 10 is made of carbon fiber material.

[0089] It should be noted that in the design of the hat-shaped rib structure, it is connected to the skin to form a closed section, which is beneficial to improving the torsional stability and buckling strength of the structure. The standard connection parts between the skin and the hat-shaped rib are completely eliminated through the method of solidification and one-piece molding and pressing. The sealing of the body structure is improved structurally, thereby improving the protective performance of the product. At the same time, a complete reinforced wall panel structure is formed to improve the integrity of the structure.

[0090] In specific implementation, the hat-shaped rib 3 is transported to the work surface by the feeder 4, and the guide block 24, the conveying guide platform 26 and the limit platform 28 adjust the position of the hat-shaped rib 3 so that it is convenient to complete the pressing operation on it through the side pressure plate 95 and the upper pressure plate 29. After the pressing operation is completed, the limit platform 28 releases the limit on the hat-shaped rib 3, and transports the hat-shaped rib 3 to the conveyor 5 through the conveying guide platform 26, and finally transports it to the placement room through the conveyor 5.

[0091] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
