Description

Technical Field

[0001] The invention relates to the technical field of composite material laying, and in particular to a composite material continuous laying alignment tool and a laying alignment method. Background Art

[0002] Composite materials are highly designable, lightweight, high in specific strength, corrosion-resistant and have excellent unique electromagnetic penetration properties, making them widely used in aerospace, automotive, sports equipment, medical equipment, electronic products and other cutting-edge industrial fields. At present, the common method of laying composite materials is direct manual laying, human eye or projection alignment, and each layer of laying needs to be vacuum compacted on a vacuum table before the next layer is laid. However, these laying methods are inefficient and it is difficult to ensure the error when laying composite materials continuously. Summary of the invention

[0003] The purpose of the present invention is to provide a composite material continuous paving alignment tool and a paving alignment method. The composite material continuous paving alignment tool of the present invention has a simple structure and, when combined with the paving alignment method of the present invention, can greatly improve the paving efficiency of composite material profiles and reduce the error during continuous paving.

[0004] The present invention is achieved through the following technical solutions:

[0005] A composite material continuous paving and alignment tool, characterized in that it includes a supporting frame, a paving platform for paving composite materials, a plurality of linked alignment baffles, a diaphragm window, a plurality of driving mechanisms and a vacuum mechanism; the paving platform is arranged in the supporting frame; one end of the diaphragm window is hinged on the supporting frame; one end of the driving mechanism is connected to the supporting frame, and the other end is hinged to the end of the diaphragm window; the linked alignment baffle is slidably arranged on the supporting frame, and one end of the linked alignment baffle can extend to the paving surface of the composite material on the paving platform, and the linked alignment baffle is used to ensure the alignment of multiple layers of composite materials during continuous paving; the driving mechanism is used to drive the linked alignment baffle to slide on the paving platform; a sealing film is connected to the diaphragm window, and the sealing film is used to cover and seal the composite material after paving is completed; the vacuum mechanism is connected to the supporting frame (specifically, the vacuum mechanism is arranged below the paving platform), and the vacuum mechanism is used to vacuum the space between the sealing film and the composite material after sealing. Specifically, the diaphragm window drives the driving mechanism to operate after it rotates (that is, the diaphragm window drives the driving mechanism to operate when it starts or is pressed down to close); the diaphragm window is linked with the linkage alignment baffle, that is, when the diaphragm window is opened, it drives the driving mechanism, and then the driving mechanism drives the linkage alignment baffle to extend to the composite material laying surface of the paving platform (used as a reference for laying alignment when the composite material is laid); when the diaphragm window is pressed down, it drives the driving mechanism in the opposite direction, and the driving mechanism controls the linkage alignment baffle to retract. In simple terms, when the diaphragm window is lifted, the linkage alignment baffle extends into place, and when the diaphragm window is pressed down, the linkage alignment baffle retracts. The composite material continuous paving alignment tooling of the present invention has a simple structure, wherein the support frame is used to install and fix the various components; the linkage alignment baffle provides an alignment standard when the composite material is laid, and can be retracted when the diaphragm window is pressed down. The linkage alignment baffle designed in the composite material continuous paving alignment tooling of the present invention can align the paving of the prepreg (i.e., composite material) each time. Since the linkage alignment baffle is provided, the paving of each layer can be simply aligned with the linkage alignment baffle, making the paving very accurate and rapid, and reducing the paving error.

[0006] Furthermore, the linkage alignment baffles correspond to the driving mechanism one by one, and a plurality of the linkage alignment baffles are arranged at equal distances along the length direction of the paving platform. It should be understood that after each linkage alignment baffle is extended onto the paving platform, its ends remain aligned. Specifically, there are no less than two linkage alignment baffles.

[0007] Furthermore, the driving mechanism is a pneumatic cylinder or a hydraulic cylinder, and the linkage of the diaphragm window and the linkage alignment baffle is achieved through the linkage principle of the pneumatic cylinder or the hydraulic cylinder.

[0008] Furthermore, a connecting plate is vertically arranged on the side of the diaphragm window facing the paving platform; and the sealing film is connected to the connecting plate.

[0009] Furthermore, the sealing film is made of latex, silicone, rubber or polyurethane. Specifically, an airtight latex, silicone or polyurethane rubber sealing film is installed on the diaphragm window, which can ensure the airtightness of the gap between the table and the diaphragm window when pressed down.

[0010] Furthermore, the vacuum pumping mechanism includes a vacuum pump and a vacuum pipe; the vacuum pump is connected to the support frame; one end of the vacuum pipe is connected to the vacuum pump, and the other end is connected to the paving platform, so as to draw a vacuum from under the paving platform. The vacuum pumping mechanism forms a vacuum between the sealing film and the composite material laying surface of the paving platform, and the vacuum pressure drives the sealing film, which in turn drives the laid composite material prepreg to be compacted and formed.

[0011] Furthermore, a timer is also provided on the support frame; the timer is electrically connected to the drive mechanism; when the preset time of the timer is reached, the timer controls the drive mechanism to open the diaphragm window. When the preset time of the timer is reached, the timer sends a signal to control the operation of the drive mechanism, and the drive mechanism opens the diaphragm window (i.e., the sealing film), and the linkage alignment baffle extends into place at the same time. After the diaphragm window is pressed down and closed, the timer starts to record the time, and the diaphragm window is automatically opened after the preset time is reached.

[0012] Furthermore, the linkage alignment baffle is slidably arranged on the support frame and one end of the linkage alignment baffle can extend to at most half of the centerline position of the composite material laying surface on the laying platform. The purpose of this design is to reserve space for laying composite materials on the laying surface of the laying platform, so that after the diaphragm window is opened to the maximum, the distance from the end of the linkage alignment baffle to the centerline position of the laying surface is half of the width of the laid composite material.

[0013] A method for continuous paving and alignment of composite materials, characterized in that the continuous paving and alignment tooling is used to pave the composite materials, comprising the following steps:

[0014] S1. When the diaphragm window is open, clean the composite material paving surface of the paving platform, and then apply a release agent; specifically, clean the composite material paving surface of the paving platform with acetone for 3-5 times, and apply Loctite 770-NC release agent on the paving surface after cleaning.

[0015] S2, checking the position of the linkage alignment baffle, and confirming that the position from the end of the linkage alignment baffle to the center line of the paving surface is half of the paving width of the composite material;

[0016] S3, laying out the first layer of composite material according to the order of the layer laying table, aligning the composite material with the end of the linkage alignment baffle during laying; and laying out in sequence;

[0017] S4, after all the composite materials are laid, the diaphragm window is pressed down, at which time the linkage alignment baffle is retracted from the paving surface, and the sealing film seals the laid composite materials; the vacuum mechanism is turned on to form a vacuum between the sealing film and the paving platform;

[0018] S5. After the vacuuming is completed, start the timer. When the preset time of the timer is reached, the timer automatically opens the diaphragm window.

[0019] Beneficial effects of the present invention:

[0020] The composite material continuous paving alignment tool of the present invention has a simple structure, can improve the paving efficiency of the composite material, and reduce the paving error; the composite material continuous paving alignment tool of the present invention is provided with a linkage alignment baffle linked with the diaphragm window, and each layer of composite material paving can be simply aligned with the linkage alignment baffle, so that the paving of the composite material is very accurate and rapid; the present invention adopts the method of linkage alignment baffle to combine two steps into one step, improves the paving efficiency and accuracy, and sets a timer countdown to automatically open, reducing additional waiting time. When the diaphragm window is opened, the linkage alignment baffle of the composite material continuous paving alignment tool of the present invention is linked to the position at the same time, and when the diaphragm window is closed, the linkage alignment baffle is linked to be retracted, and no manual operation is required, and the alignment positioning position is accurate each time, without error. In the process of laying operations of continuous multi-layer composite prepregs, manual positioning is not required, and no error will be generated, so that the production efficiency and accuracy are high.
