Description

Technical Field

[0001] This utility model relates to the field of material bonding, and in particular to a surface bonding device for a U-shaped structural component. Background Technology

[0002] In recent years, with the increasing demand from consumers for product appearance, texture, and tactile experience, soft-pack materials (such as microfiber and fabrics) have been increasingly widely used in automotive interiors, 3C electronic products, and other fields. These materials, when bonded to the outer surface of structural components, not only enhance the visual appeal and comfort of the product but also provide cushioning, wear resistance, and noise reduction. However, existing technologies still face many bottlenecks in the bonding process for the outer surface of U-shaped structural components. Due to the complex curved surface features formed by the side walls and bottom of U-shaped components, the soft-pack material must adapt to changes in curvature in different directions during bonding. Existing automated bonding equipment is mostly designed for planar or simple curved surfaces and lacks the dynamic adaptive capability for U-shaped structural components. For small-batch, multi-variety U-shaped component production scenarios, relying on manual tooling adjustments or segmented bonding processes is cumbersome and time-consuming, making it difficult to meet the demands of efficient production. Furthermore, the high material waste and rework costs caused by bonding failures restrict the large-scale application of soft-pack technology on complex, irregularly shaped components. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a device for surface bonding of U-shaped structural components, which can adaptively bond curved surfaces, thereby promoting the widespread application of flexible packaging technology in the manufacturing of irregularly shaped structural components.

[0004] This utility model provides a surface bonding device for a U-shaped structural component, including a support platform on which the following is mounted:

[0005] A support block is provided on the upper part of the support platform, and the upper surface of the support block is provided with a contour structure that matches the bottom of the U-shaped structural component.

[0006] The flipping mechanism includes two clamping blocks located on both sides of the support block. The upper surface of the clamping block is provided with a contoured structure that adapts to the side of the U-shaped structure. The upper surface of the clamping block and the upper surface of the support block are combined to form a support surface. The edge of the upper surface of the clamping block and the edge of the upper surface of the support block are close to each other to form a rotation axis.

[0007] The power mechanism has its output end connected to the flipping mechanism to simultaneously drive the two clamping blocks to rotate in the same or opposite directions around the rotation axis.

[0008] Preferably, the power mechanism includes a U-shaped mounting frame, and two mounting plates arranged opposite each other are also mounted on the upper part of the support platform. The U-shaped mounting frame is rotatably connected between the two mounting plates through a rotating shaft, and the central axis of the rotating shaft is on the same straight line as the rotation axis. The inner side of the U-shaped mounting frame is fixedly connected to the lower surface of the clamping block.

[0009] Preferably, the power mechanism further includes a drive device, which includes a slide rail and a slider. The slide rail is installed on both sides of one of the mounting plates. The slider has a groove corresponding to the slide rail, which allows the slider to move up and down on the slide rail. A rack is installed on the slider, and a gear that meshes with the rack is fixedly sleeved on the rotating shaft.

[0010] Preferably, a cylinder is mounted on the mounting plate, and the movable end of the cylinder is fixedly connected to the slider via a connecting plate.

[0011] Preferably, it also includes a vacuum generator, wherein a first ventilation pipe is provided inside the support block, and a second ventilation pipe is provided inside the clamping block. One end of the first ventilation pipe is connected to the upper surface of the support block, and one end of the second ventilation pipe is connected to the upper surface of the clamping block; the other ends of the first ventilation pipe and the second ventilation pipe are both connected to the output end of the vacuum generator.

[0012] This utility model provides a U-shaped structural component surface bonding device that significantly improves the accuracy and efficiency of soft-pack material bonding through the synergistic effect of contour-following structural design and automated mechanism. The contour-following surfaces of the support block and clamping block precisely adapt to the contour of the U-shaped structural component. Combined with the negative pressure adsorption force generated by the vacuum generator, the soft-pack material is firmly fixed to the support surface before bonding, effectively avoiding material displacement or wrinkling during processing. The flipping mechanism achieves synchronous flipping of the clamping block through gear and rack transmission and cylinder drive, ensuring the stability and consistency of the soft-pack material during bending bonding. The overall structure adopts a U-shaped mounting bracket and a rotating shaft coaxial design and is driven by a cylinder. Compared with motor drive, the structure is simpler and more stable, significantly improving product yield while reducing production costs.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] To better illustrate the purpose and working principle of this utility model, such as Figure 1 The diagram illustrates the shape of a U-shaped structural component. The purpose of this invention is to adhere a layer of soft material to the outer surface of the U-shaped structural component. To achieve this purpose, a surface-adhesive device for the U-shaped structural component is provided, the specific solution of which is as follows:

[0025] like Figure 2 As shown, a surface bonding device for a U-shaped structural component includes a support platform 1, on which the following are mounted:

[0026] Support block 2, the support block 2 is disposed on the upper part of support platform 1, and the upper surface of the support block 2 is provided with a contour structure that matches the bottom of the U-shaped structural component.

[0027] The flipping mechanism includes two clamping blocks 3 located on both sides of the support block. The upper surface of the clamping block 3 is provided with a contour structure that is adapted to the side of the U-shaped structure. The upper surface of the clamping block 3 and the upper surface of the support block 2 are combined to form a support surface. The edge of the upper surface of the clamping block 3 and the edge of the upper surface of the support block 2 are close to form a rotation axis 4.

[0028] The power mechanism 5 has its output end connected to the flipping mechanism to simultaneously drive the two clamping blocks 3 to rotate in the same or opposite directions around the rotation axis.

[0029] In this embodiment, as shown Figure 2 As shown, after the power mechanism 5 drives the two clamping blocks to rotate in opposite directions, the support surface is in an unfolded state. During processing, the soft packaging material is laid flat on the support surface, and then the U-shaped structural component is placed on the soft packaging material. The power mechanism 5 is started, driving the two clamping blocks 3 to rotate in the same direction. The clamping blocks 3 push the soft packaging material to bend until it is attached to both sides of the U-shaped structural component, completing the attachment operation. At this time, the clamping blocks are in a position as if... Figure 3 state.

[0030] In this embodiment, it should be noted that the soft packaging material needs to be sprayed with adhesive or a hot melt adhesive film with a backing beforehand. After the soft packaging material is attached to both sides of the U-shaped structure, the hot melt adhesive film with a backing needs to be heated by a hot air blower or other equipment to activate the hot melt adhesive film and achieve the bonding between the soft packaging material and the U-shaped structure.

[0031] In this embodiment, a robotic arm can be used when placing the U-shaped structural component. By setting up the robotic arm, the automation rate can be improved, labor costs can be reduced, and production efficiency can be increased. In addition, the robotic arm can more accurately control the placement position of the U-shaped structural component, thus improving accuracy. After the robotic arm places the U-shaped structural component, it does not remove itself and applies a certain pressure, which can fix the soft packaging material and the U-shaped structural component, making it difficult for the soft packaging material and the U-shaped structural component to move during processing.

[0032] like Figure 2-4 As shown, in a specific embodiment, the power mechanism includes a U-shaped mounting bracket 51, and two mounting plates 6 are also mounted on the upper part of the support platform 1. The U-shaped mounting bracket 51 is rotatably connected between the two mounting plates 6 through a rotating shaft, and the central axis of the rotating shaft is on the same straight line as the rotating axis 4. The inner side of the U-shaped mounting bracket 51 is fixedly connected to the lower surface of the clamping block 3.

[0033] As can be seen in this embodiment, when the U-shaped mounting bracket 51 rotates, it will cause the clamping block 3 to rotate around the rotation axis 4.

[0034] In one specific embodiment, the power mechanism 5 further includes a drive device, which includes a slide rail 52 and a slider 53. The slide rail 52 is installed on both sides of one of the mounting plates 6. The slider 53 has a groove corresponding to the slide rail 32, which allows the slider 53 to move up and down on the slide rail 52. A rack 531 is installed on the slider 53, and a gear 54 that meshes with the rack 531 is fixedly sleeved on the rotating shaft.

[0035] As can be seen in the original embodiment, when the slider 53 moves up and down on the slide rail 52, it will cause the gear 54 to rotate, thereby driving the U-shaped mounting bracket 51 to rotate through the rotating shaft.

[0036] In one specific embodiment, a cylinder 61 is mounted on the mounting plate 6, and the movable end of the cylinder 61 is fixedly connected to the slider 53 through a connecting plate.

[0037] In this embodiment, the cylinder 61 pushes the slider 52 to move up and down.

[0038] like Figure 2 As shown in Figure 4, the U-shaped structural component surface bonding device provided by this utility model also includes a vacuum generator 7. A first ventilation pipe is provided inside the support block 2, and a second ventilation pipe is provided inside the clamping block 3. One end of the first ventilation pipe is connected to the upper surface of the support block 2, and one end of the second ventilation pipe is connected to the upper surface of the clamping block 3. The other ends of the first ventilation pipe and the second ventilation pipe are both connected to the output end of the vacuum generator 7.

[0039] In this embodiment, the vacuum generator 7 generates negative pressure, which, through the first ventilation pipe and the second ventilation pipe, causes the support surface to generate suction. After the soft packaging material is placed in the preset position, the soft packaging material is adsorbed onto the support surface, making it less likely for the soft packaging material to shift and thus reduce accuracy.

[0040] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
