Description

Technical Field

[0001] This utility model relates to the field of edge banding technology for the inner hole skin of low-pressure injection molded parts, and specifically to an edge banding mechanism. Background Technology

[0002] Edge wrapping is a process of wrapping an outer skin material around the edge of an object, primarily used to enhance aesthetics and protect the edges. The wrapping equipment mainly consists of heating and wrapping devices. The specific process involves first heating the outer skin using the heating device until the PP foam layer is slightly molten, and then using the wrapping device to wrap the heated outer skin over the frame.

[0003] However, for some parts with internal openings that need to be covered with a skin, the skin needs to be gradually pushed from the outer edge of the part to the inner surface and then welded. Currently, the commonly used methods are mainly manual covering and welding or welding by a six-axis robot to simulate human movements.

[0004] Although using robots can significantly reduce labor costs, the robots themselves are relatively expensive and require frequent maintenance and debugging. In actual use, the robots need to use tools with spikes to pull the outer skin to the inner surface, which is not only complicated and slow, but also takes a long time to complete the edging operation, which greatly affects work efficiency. Utility Model Content

[0005] Therefore, this utility model provides an edge-binding mechanism to solve the problem of low work efficiency caused by the complex and slow-paced movements of robots in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The main frame, with the first lifting element installed inside;

[0009] The first translational component is connected to the first lifting element at its bottom. The first lifting element is adapted to push the first translational component and the second translational component to move up and down. The first translational component is equipped with the second lifting element.

Furthermore, the retraction of the pusher does not affect the loading and unloading of parts, ensuring production efficiency. It also solves the problem of low work efficiency caused by the complex and slow movement of robots in existing technologies. Attached Figure Description

[0039] Please refer to this as well. Figures 1-7 This utility model discloses an edge-wrapping mechanism for wrapping the surface of the interior trim 6 on the fixture 5. The technical solution will be described below by way of specific embodiments.

[0040] In a specific embodiment of this utility model, the edging mechanism mainly includes a main frame 1, a first translational component 2, and a second translational component 3. A first lifting element 7 is installed inside the main frame 1. The bottom of the first translational component 2 is driveably connected to the first lifting element 7, thereby driving the first translational component 2 and the second translational component 3 to move up and down synchronously. A second lifting element 8 is installed on the first translational component 2, and is drively connected to the second translational component 3, thereby driving the second translational component 3 to move up and down. In this embodiment, the first translational component 2 and the second translational component 3 are each equipped with two pairs of pusher assemblies 9, and drive the two pairs of pusher assemblies 9 to open and close.

[0041] In some embodiments, the main frame 1 includes a worktable 11 and a support column 13. A lifting bracket 12 is installed at the bottom of the worktable 11, and a first lifting element 7 is installed on the lifting bracket 12. The first lifting element 7 passes through a through slot 14 located in the middle of the lifting bracket 12 and is connected to a first translational assembly 2, thereby making the structure of the main frame 1 more stable and providing support through the worktable 11. On the other hand, the top of the support column 13 is connected to the fixture 5, and the bottom of the support column 13 is fixed on the worktable 11, thereby allowing the fixture 5 to be connected to the worktable 11. In this embodiment, the first lifting element 7 and the second lifting element 8 are push-pull electromagnets or cylinders, thereby driving the equipment to operate by pneumatic or electric drive.

[0042] In some embodiments, the first translational assembly 2 includes a first mounting plate 21 and a support rod 23. A pair of drive elements 22 are provided at both ends of the first mounting plate 21, and each drive element 22 is connected to a pusher assembly 9. The first mounting plate 21 is connected to the top of the support rod 23, and the bottom of the support rod 23 is fixedly mounted on the worktable 11. On the other hand, the second translational assembly 3 includes a second mounting plate 31 and a pair of drive elements 32. A guide post 33 is provided at the bottom of the second mounting plate 31 and is slidably inserted into the first mounting plate 21, providing guidance for the second mounting plate 31 to slide up and down. A pair of drive elements 32 are provided at both ends of the second mounting plate 31, and another pair of pusher assemblies 9 are mounted on the drive elements 32.

[0043] Based on the previous embodiment, this device has a complete workflow. First, drive element 1 22 and drive element 2 32 extend, and the cutter head 91 moves inward away from the interior trim 6, at which point the interior trim 6 can be placed on the fixture 5. In the first step, the first lifting element 7 extends, driving the second lifting element 8 to rise. In the second step, drive element 1 22 retracts, driving the two sets of pusher assemblies 9 to horizontally and tightly adhere the skin to the injection molded frame. In the third step, drive element 2 32 retracts, driving the two sets of pusher assemblies 9 to horizontally and tightly adhere the skin on the other side to the injection molded frame. In the fourth step, the second lifting element 8 retracts, driving all the pusher assemblies 9 to descend, tightly adhering the skin to the injection molded frame in the vertical direction. In the fifth step, ultrasonic welding welds the skin and the frame together. In the sixth step, the cylinders retract sequentially, and the structure returns to its original state.

[0044] In some embodiments, the pusher assembly 9 includes a cutter head 91 and a limiting bolt 93. The end of the cutter head 91 is connected to the handle 92, and the end of the limiting bolt 93 is screwed into the handle 92. In this embodiment, the cutter head 91 has a rough textured surface to ensure friction with the surface. It should be noted that each set of cylinders for actuation has an adjustable limiting bolt mechanism to adjust the distance between the pusher and the workpiece, ensuring the fit between the surface and the injection-molded skeleton. Specifically, the sides of the drive element 1 22 and the drive element 2 32 are provided with limiting elements 4. The screw of the limiting bolt 93 is inserted into the limiting element 4, and the head of the limiting bolt 93 is adapted to abut against the limiting element 4.
