Abstract
Description

[0001] The utility model relates to the packaging field of composite material curing molding technology, in particular to an auxiliary material paving device for composite material pressure bag molding packaging. Background Art
[0002] During the composite pressure bag forming and packaging stage of the autoclave molding technology, auxiliary materials need to be laid between the pressure equalizing plates. From the inside to the outside, they are peelable cloth (release cloth), porous isolation film, adhesive absorption layer, and non-porous isolation film.
[0003] However, the laying process is easily affected by external forces and electrostatic induction of the auxiliary material film. The auxiliary material is not easy to lay flat, and material wrinkles and local deformations appear. In the subsequent curing stage, the resin flowability at high temperature increases, and the resin flow process increases the degree of wrinkles and local deformation of the auxiliary material, which reduces the surface flatness and thickness uniformity of the composite material sheet. At present, the high-temperature tape fixing method is usually adopted, and the auxiliary material is fixed with high-temperature tape during the process of flattening. This method is time-consuming and labor-intensive, and the flattening effect is not good. Resin accumulation is prone to occur in the bonding area of the high-temperature tape, which has an adverse effect on the thickness controllability and demolding of the molded sheet. Therefore, in order to solve the above-mentioned technical problems, ensure the uniformity of the thickness of the composite material sheet and the convenience of demolding, and improve the surface flatness and work efficiency of the molded sheet, it is of great significance to design a kind of auxiliary material flattening tooling for composite pressure bag molding.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.
[0033] The utility model provides an auxiliary material paving device for composite material pressure bag molding packaging, such as Figure 1 As shown, the auxiliary material flattening device for composite material pressure bag forming packaging includes three parts, namely a pressure equalizing plate 1, an electromagnet module 2, and a tensioning positioning rod 3.
[0034] For ease of understanding, select Figure 1 The AA section shown in the main view (b) is subjected to structural analysis. The pressure equalizing plate 1 has a relative non-working surface 101 and a working surface 102. The electromagnet module 2 is arranged on the non-working surface 101. When the device is working, the tensioning positioning rod 3 is arranged on the working surface 102 and can be adsorbed by the electromagnet module 2 to achieve the purpose of tensioning the corners of the auxiliary material.
[0035] In some embodiments, Figure 1 and Figure 2 As shown, a plate area 103 and a thin-walled area 104 are provided on the pressure equalizing plate 1 , wherein the thin-walled area 104 is an area formed on the working surface 102 of the pressure equalizing plate 1 by providing a thin-walled structure on the pressure equalizing plate 1 .
[0036] The sheet area 103 is used as a mold for sheet solidification, so that the sheet can achieve the desired shape and performance during the solidification process. This area includes a sheet sampling area and a waste area.
[0037] The thin-walled area 104 is used as the placement area for the tensioning positioning rod. Through the structural optimization here (thin walls at both ends form a cavity to facilitate resin overflow), the resin accumulation in the edge area of the plate is avoided, and the resin in the center of the plate is evenly overflowed to the surroundings, thereby improving the thickness uniformity of the formed plate (see Figure 1 , Figure 2 ). When a pair of equalizing plates compress the plate in two directions, the cavity at the thin-wall structure facilitates the removal of the tensioning positioning rod 3.
[0038] In actual implementation, a uniform plate 1 has a thin-walled area 104, and the thin-walled area 104 is located around the uniform plate 1. Correspondingly, a plurality of tensioning positioning rods 3 are arranged to press the two ends of the material. Similarly, the number of electromagnet modules 2 is consistent with that of the uniform plate 1, and they are respectively arranged at corresponding positions on the non-working surface 101 of the pressure-equalizing plate 1 corresponding to the thin-walled area 104, for adsorbing the tensioning positioning rods 3.
[0039] In some embodiments, Figure 2 As shown, the electromagnet module 2 is provided with four groups of coils, namely the first coil D1, the second coil D2, the third coil D3, and the fourth coil D4. Magnetic resistance materials are installed between each group of coils to ensure that each group of coils can work independently, so that no electromagnetic force is generated between the four groups of coils. The shape of the electromagnet module is strip-shaped, so that the electromagnet coils are closed from head to tail to form a ring structure, and the ring structure is selectively customized according to the working conditions (if a square is required, a square is set; if a circle is required, a circle is set). The electromagnet module 2 contacts the non-working surface 101 of the equalizing plate 1, and the side in contact with the equalizing plate 1 is provided with a cavity suction cup 4 (press to adsorb, lift to detach), which ensures the convenience of disassembly and assembly of the electromagnet module 2.
[0040] In some embodiments, Figure 1 and Figure 2 As shown, the tensioning and positioning rod 3 includes a first polished rod Z1, a second polished rod Z2, a third polished rod Z3 and a fourth polished rod Z4, wherein a traction rope is arranged on the fourth polished rod Z4. The tensioning and positioning rod 3 is used in conjunction with the electromagnet module 2 to tension the edges and corners of the auxiliary material, thereby ensuring that the auxiliary material is laid evenly.
[0041] It should be noted that, in specific operation, the first polished rod Z1, the second polished rod Z2, the third polished rod Z3 and the fourth polished rod Z4 are adsorbed by the first coil D1, the second coil D2, the third coil D3 and the fourth coil D4, respectively, which work independently. The first coil D1, the second coil D2, the third coil D3 and the fourth coil D4 have corresponding adsorption areas when they work. When the tensioning and positioning rod 3 is used, the first polished rod Z1, the second polished rod Z2, the third polished rod Z3 and the fourth polished rod Z4 should correspond to the adsorption areas of the first coil D1, the second coil D2, the third coil D3 and the fourth coil D4, respectively, so as to realize the auxiliary fixing effect of each polished rod on the corresponding material.
[0042] like Figure 3 The figure shows the operation flow of the auxiliary material paving device for composite material pressure bag molding and packaging illustrated in this embodiment. Figure 4 The BB cross-sectional view of the auxiliary material paving device for composite material pressure bag molding and packaging illustrated in this embodiment in the use state, the auxiliary material paving device for composite material pressure bag molding and packaging is operated through the following steps when in use:

At this time, the first coil D1 absorbs the first polished rod Z1, compresses and adjusts the non-porous isolation film 5 to make it flat and wrinkle-free.
[0045] Step 3, lay the adhesive layer 6, open the second coil D2 in the electromagnet module 2, and place the second polished rod Z2 on the working surface of the thin-walled structure. At this time, the second coil D2 absorbs the second polished rod Z2, presses and adjusts the adhesive layer 6 to make it flat and wrinkle-free.
[0046] Step 4, disconnect the first coil D1 in the electromagnet module 2 and remove the first polished rod Z1.
[0047] Step 5, laying the porous isolation film 7, opening the third coil D3 in the electromagnet module 2, placing the third polished rod Z3 on the working surface of the thin-walled structure, at this time the third coil D3 absorbs the third polished rod Z3, pressing and adjusting the porous isolation film 7 to make it flat and wrinkle-free.
[0048] Step 6, disconnect the second coil D2 in the electromagnet module 2, and remove the tensioned second polished rod Z2.
[0049] Step 7, laying the demoulding cloth 8, opening the fourth coil D4 in the electromagnet module 2, placing the fourth polished rod Z4 on the working surface of the thin-walled structure, at this time the fourth coil D4 absorbs the fourth polished rod Z4, pressing and adjusting the demoulding cloth to make it flat and wrinkle-free.
[0050] Step 8, disconnect the third coil D3 in the electromagnet module 2, and remove the third polished rod Z3.
[0051] Step 9, select a new equalizing plate 1, repeat steps 1 to 8 to obtain two uniform plates 1 with fixed materials, place the uncured plate blank 9 on the plate area of the equalizing plate 1, and the two equalizing plates 1 press the plates in both directions.
[0052] Step 10, disconnect the fourth coil D4 in the electromagnet module, and pull the traction rope to remove the fourth bare rod Z4.
[0053] After completing the above steps, remove the electromagnet module, and the laying of the auxiliary material is completed.
[0054] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
