Description

Technical Field

[0001] This application relates to the technical field of honeycomb panel bonding and curing, and in particular to a honeycomb panel bonding and curing platform. Background Technology

[0002] Honeycomb panels adopt a "honeycomb sandwich" structure, which uses high-strength alloy aluminum plates as the face and back plates and aluminum honeycomb cores as adhesives. After being manufactured under high temperature and high pressure, they are cooled and cured to form a composite panel, which is widely used in civil buildings, aviation, aerospace and other fields.

[0003] When manufacturing honeycomb panels, the bonded honeycomb panels are generally pressed and formed using a hot press. For irregularly shaped and large-sized honeycomb panels, the press is generally not able to press them. Instead, the product is glued and then attached to a forming workbench or forming mold. The pressure is then applied using a bag-pressing film to solidify the product.

[0004] In the existing technology, the honeycomb panels are placed directly on the workbench. Due to manual placement and the pressure applied by the bag-pressing film, the honeycomb panels will shift, causing some honeycomb panels to not be completely located in the heating area. Some edges of the honeycomb panels are prone to being without adhesive, resulting in a reduction in the curing effect of the honeycomb panels. Utility Model Content

[0005] To address the aforementioned issues, this application provides a honeycomb panel bonding and curing platform.

[0006] The honeycomb veneer bonding and curing platform provided in this application adopts the following technical solution:

[0007] A honeycomb panel bonding and curing platform for curing honeycomb panels includes a workbench. The workbench is provided with a positioning frame, a vacuum bag and a heating component. The positioning frame abuts against the heating component and presses the edge of the vacuum bag against the positioning frame. A plurality of positioning posts are evenly arranged on the workbench, and each positioning post abuts against the inner sidewall of the positioning frame.

[0008] By adopting the above technical solution, multiple positioning posts fix the position of the positioning frame. When placing the honeycomb panel, the honeycomb panel is placed inside the positioning frame, which can reduce the low curing quality of the honeycomb panel caused by the position of the honeycomb panel deviating from the heating area and improve the curing efficiency of the honeycomb panel.

[0009] Preferably, a sealing component is provided at the contact area between the worktable and the positioning frame.

[0010] By adopting the above technical solution, when the positioning frame presses the edge of the vacuum bag, it can make the vacuum bag and the worktable more closely contact each other, reducing the leakage of air during the vacuuming process.

[0011] Preferably, the sealing component includes a sealing protrusion and a sealing gasket. The sealing protrusion is mounted on the positioning frame, and the sealing gasket is mounted on the worktable. The sealing gasket has a groove for engaging with the sealing protrusion, and the sealing protrusion fits against the inner wall of the groove.

[0012] By adopting the above technical solution, the fit between the sealing convex strip and the groove increases the length of the sealing path, further improving the sealing effect; and when installing the positioning frame, the structure of the sealing convex strip and the groove has a certain guiding and positioning function, which can improve the installation efficiency.

[0013] Preferably, the sealing convex strip has a circular arc cross-section.

[0014] By adopting the above technical solution, the sealing strip can reduce the wear of the vacuum bag at the pressing point during the pressing process, thus extending the service life of the vacuum bag.

[0015] Preferably, the heating assembly includes heat insulation cotton, a heating plate, and heat-resistant glass, which are sequentially attached to the worktable.

[0016] By adopting the above technical solutions, the heat insulation cotton has a certain heat insulation function, which can isolate the temperature of the heating plate, reduce the heat of the workbench, and extend the service life of the workbench; the heat-resistant glass has good thermal conductivity, which can make the heat of the heating plate evenly transferred to the honeycomb single panel, thereby reducing the situation where the surface quality of the honeycomb single panel is affected by local overheating of the heating plate.

[0017] Preferably, the positioning frame is fixed to the worktable by multiple buckles.

[0018] By adopting the above technical solution, the installation and disassembly of the positioning frame are convenient. Multiple buckles fix the positioning frame and can provide a certain downward pressure to the positioning frame, so that the edges of the vacuum bag are pressed more tightly.

[0019] Preferably, the vacuum bag is provided with a vacuum pumping assembly, and the vacuum bag has an air extraction port, and the vacuum pumping assembly is connected to the air extraction port.

[0020] By adopting the above technical solution, the air inside the vacuum bag can be automatically extracted during the curing of the honeycomb panel, and the pressure of the vacuum bag can be used to provide pressure to the honeycomb panel, thereby improving the curing effect of the honeycomb panel.

[0021] Preferably, a sliding groove is provided on the inner sidewall of the positioning frame, and multiple sets of moving components are slidably connected in the sliding groove. Each moving component includes a moving block and a pressure plate. The moving block is slidably connected in the sliding groove and has a moving slot. The pressure plate is slidably connected in the moving slot in the vertical direction.

[0022] By adopting the above technical solution, the honeycomb panels are pre-fixed before vacuuming, making it less likely for the honeycomb panels to shift during the vacuuming process, which can further improve the curing effect of the honeycomb panels.

[0023] Preferably, the movable groove is provided with a spring, one end of which abuts against the inner wall of the movable groove and the other end abuts against the pressure plate.

[0024] By employing the above technical solution, the worker lifts the pressure plate, at which point the spring is compressed, and then places the honeycomb panel under the pressure plate. The worker then releases the pressure plate; the spring's rebound force provides assistance to the pressure plate, thereby applying pressure to the bag and further improving the curing effect.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up positioning frames and positioning posts, the heating area of ​​the honeycomb panel is determined, reducing the occurrence of low curing quality of the honeycomb panel due to its placement deviating from the heating area, and improving the curing efficiency of the honeycomb panel.

[0027] 2. By designing sealing components, the sealing performance between the vacuum bag and the worktable is improved, reducing the possibility of air leakage during the vacuuming process.

[0028] 3. By sliding the positioning frame and the moving component together, the honeycomb panel is pre-fixed before vacuuming, making it less likely for the honeycomb panel to shift during vacuuming and improving the curing effect of the honeycomb panel. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0034] This application discloses a honeycomb panel bonding and curing platform in its embodiments, referring to... Figure 1 and Figure 2 A honeycomb panel bonding and curing platform is disclosed for curing honeycomb panels. It includes a workbench 1, on which a positioning frame 3, a vacuum bag 9, and a heating component 2 are mounted. The vacuum bag is transparent or semi-transparent and is detachably connected to the workbench 1 via the positioning frame 3 for pressing the edges of the vacuum bag 9. The heating component 2 is disposed within the positioning frame 3, with its edge abutting against the inner wall of the positioning frame 3. Multiple positioning posts 6 are evenly distributed on the workbench 1; in this embodiment, four positioning posts 6 are preferably located at the four corners of the positioning frame 3 and abut against the inner wall of the positioning frame 3.

[0035] Reference Figure 2 A sealing component 5 is provided at the contact area between the workbench 1 and the positioning frame 3. The sealing component 5 includes a sealing protrusion 51 and a sealing gasket 52. The cross-sectional shape of the sealing protrusion 51 can be square, rectangular, or arc-shaped. In this embodiment, the cross-sectional shape of the sealing protrusion 51 is preferably arc-shaped, which can reduce the wear of the vacuum bag 9 at the pressing point. The sealing protrusion 51 is installed on the side of the positioning frame 3 near the workbench 1, and the sealing gasket 52 is installed on the workbench 1. The sealing gasket 52 has a groove for cooperating with the sealing protrusion 51. The sealing protrusion 51 fits against the inner wall of the groove, increasing the length of the sealing path and further improving the sealing effect.

[0036] Reference Figure 2 The heating component 2 consists of heat insulation cotton 21, a heating plate 22, and heat-resistant glass, which are sequentially attached to the workbench 1. The heat insulation cotton 21 has a certain heat insulation function, which can isolate the temperature of the heating plate 22, reduce the heat on the workbench 1, and extend the service life of the workbench 1. By setting the heat-resistant glass on the heating plate 22, the heat of the heating plate 22 can be evenly conducted to the honeycomb single board, which can improve the curing effect of the honeycomb single board.

[0037] Reference Figure 1 and Figure 2 The positioning frame 3 is fixed by multiple buckles 7 evenly arranged around the working area, which facilitates the installation and removal of the positioning frame 3. When the buckles 7 are locked, the edge of the vacuum bag 9 can be further pressed to improve the vacuuming effect. In addition, when the honeycomb single panel is placed manually, the positioning frame 3 can be reduced to deviate, thus improving the curing effect of the honeycomb single panel.

[0038] Reference Figure 1The vacuum bag 9 is equipped with a vacuum assembly 8, which includes a vacuum pump 81 and a vacuum tube 82. The vacuum bag 9 has an air extraction port, and the vacuum tube and the air extraction port are detachably connected. The vacuum pump is used to extract the air from the vacuum bag 9, and the vacuum bag 9 covers the honeycomb panel, providing pressure to the honeycomb panel and improving the curing effect of the honeycomb panel.

[0039] Reference Figure 1 and Figure 3 The inner wall of the positioning frame 3 is provided with a sliding groove, and multiple sets of moving components 4 are slidably connected in the sliding groove.

[0040] The moving component 4 includes a moving block 41 and a pressure plate 42. The moving block 41 is slidably connected in a sliding groove, and a moving slot is formed on the moving block 41. The pressure plate 42 is slidably connected in the moving slot in the vertical direction. A spring 43 is provided in the moving slot, with one end of the spring 43 fixed to the upper top surface of the moving slot and the other end connected to the pressure plate 42. There can be two sliding grooves arranged opposite each other and located on the inner side wall of the positioning frame 3. At the same time, there are two moving blocks 41 in each set of moving components 4, arranged opposite each other and located in two sliding grooves respectively. At this time, the pressure plate 43 is placed between the two moving blocks 41. Before vacuuming, the pressure plate 43 pre-fixes the honeycomb single panel. During the vacuuming process, the honeycomb single panel is not easy to shift. The spring 43 on the moving block 41 can increase the pressure applied by the pressure plate 43 to the honeycomb single panel, further improving the curing effect of the honeycomb single panel.

[0041] The implementation principle of a honeycomb single-panel bonding and curing platform in this application embodiment is as follows:

[0042] Place the honeycomb panel on the heating component 2 inside the positioning frame 3, lay the vacuum bag 9 on the honeycomb panel, fix the positioning frame 3 on the platform with the fixing buckle 7, press the edge of the vacuum bag 9, lift the pressure plate 42, slide the moving component 4 above the honeycomb panel, release the pressure plate 42, and press the honeycomb panel with the spring 43 in the moving groove and the weight of the pressure plate 42 itself, and then use the vacuuming component 8 to connect the vacuum bag 9 to perform vacuuming to achieve the curing of the honeycomb panel.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
