Description

Technical Field

[0001] This utility model is applicable to automotive air ducts, and more specifically to air duct sponge pasting, relating to an automatic sponge pasting device for air duct assemblies. Background Technology

[0002] Automotive air ducts are a core component of the car's internal air circulation system. Their main function is to guide airflow, thereby achieving temperature regulation, ventilation, and aerodynamic optimization within the vehicle.

[0003] Automotive air ducts are typically made of thermoplastics (such as polypropylene (PP), polyamide (PA), ABS, etc.) or composite materials (such as glass fiber reinforced plastics and carbon fiber composites) due to their advantages such as lightweight, good formability, and low cost. Their structures are complex and often include designs such as bends, bifurcations, and irregular cross-sections.

[0004] With the increasing demands for lightweighting and environmental protection in automobiles, the manufacturing process of automotive air ducts needs to balance efficiency, precision, and environmental friendliness. For example, rapid prototyping can be achieved through hot pressing technology, while the problem of insufficient cooling efficiency needs to be solved.

[0005] During assembly or transportation, the sponge absorbs vibrations and protects the integrity of the duct structure. It also seals gaps between the duct and the installation location, ensuring airtightness within the air conditioning or ventilation system and enhancing airtightness. In scenarios requiring sound insulation, the sponge acts as a shock-absorbing layer, reducing noise transmission during operation. Furthermore, in dust-proof scenarios, it can function as a filter layer, minimizing impurities entering the duct system.

[0006] However, existing methods of applying sponges typically involve manual cutting and pasting onto the outer wall of the air duct, resulting in low efficiency and an inability to perform rapid processing. Utility Model Content

[0007] One objective of this invention is to provide a new technology solution for an automatic sponge applicator for air duct assemblies.

[0008] According to a first aspect of the present invention, an automatic sponge applicator for an air duct assembly is provided, comprising a base plate, wherein a rotating mechanism, a lifting mechanism and a power mechanism are mounted on the upper part of the base plate;

[0009] The rotating mechanism includes a rotating disk, with movable slots on both sides of the upper part of the rotating disk. Movable blocks are movably installed inside the movable slots. A crank rod is fixedly connected to one side of each movable block on both sides. A threaded block is fixedly installed at the upper part of one end of the crank rod. A first positioning plate is fixedly installed on one side of the upper part of the rotating disk. A double-ended screw is movably installed inside the first positioning plate. The threaded blocks on both sides are respectively threaded onto the double-ended screw.

[0010] Optionally, the rotating disk has a placement groove in the middle, a pushing block is fixedly installed on one side of the moving block, a second positioning block is fixedly installed at one end of the rotating disk, one end of the double-ended screw is movably connected to the second positioning block, and a rotating handwheel is fixedly installed at the other end of the double-ended screw.

[0011] Optionally, a first shaft is fixedly provided at the bottom of the rotating disk, the bottom end of the first shaft is movably connected to the upper end of the base plate, and a first rotating wheel is connected to the key on the first shaft.

[0012] Optionally, the lifting mechanism includes a lifting screw movably connected to the base plate, a second rotating wheel keyed to the lower part of the lifting screw, and a servo motor in the power mechanism. The output end of the servo motor is connected to an output shaft movably connected to the base plate, and a third rotating wheel is keyed to the output shaft. A transmission belt is wound sequentially on the first rotating wheel, the second rotating wheel, and the third rotating wheel.

[0013] Optionally, a lifting plate is threadedly connected to the lifting screw, and an installation rod is fixedly provided on the upper end face of one side of the lifting plate.

[0014] Optionally, a limiting housing is fixedly installed on the middle of the base plate, and a cover is fixedly provided at the upper end of the limiting housing. The lifting screw and the second rotating wheel are disposed inside the limiting housing, and the upper end of the lifting screw is movably connected to the lower end face of the cover.

[0015] Optionally, the bottom of the limiting housing is provided with a through hole, the transmission belt is movably located inside the through hole, a limiting groove is provided on one side of the limiting housing, and the middle part of the lifting plate is movably located inside the limiting groove.

[0016] The beneficial effects of this utility model are:

[0017] In use, this utility model transmits power through a power mechanism, thereby driving the rotating mechanism and the lifting mechanism. The power mechanism also enables the rotating mechanism and the lifting mechanism to rotate synchronously through a transmission belt. Maintaining synchronous rotation of the rotating mechanism and the lifting mechanism facilitates the simultaneous lifting of the sponge by the lifting mechanism when the rotating mechanism drives the air duct to rotate, thus achieving automated sponge adhesion to the outer wall of the air duct.

[0018] This invention features a clamping device on the rotating mechanism for stable clamping and fixing of the air duct. A double-headed screw drives and adjusts the threaded blocks on both sides synchronously. When the double-headed screw rotates, it drives the crank rod through the threaded blocks on both sides to move and adjust the moving block. This causes the moving block to drive the pushing block to clamp the air duct, allowing the air duct to rotate with the rotating disk. This facilitates the even wrapping of the sponge around the outer wall of the air duct.

[0036] In this embodiment, preferably, the lifting mechanism 3 includes a lifting screw 301 movably connected to the base plate 1, and a second rotating wheel 302 is keyed to the lower part of the lifting screw 301.

The sponge is placed on the mounting rod 304 of the lifting plate 303. Before starting, the sponge is first wrapped around the bottom of the air duct. Then the servo motor 403 outputs power. When the lifting screw 301 and the first shaft 201 rotate, they can drive the rotating disk 203 and the air duct to rotate, so that the sponge can be wrapped around the air duct. Under the drive of the lifting screw 301, the lifting plate 303 can make the sponge gradually rise, so that the sponge can be evenly wrapped around the outer wall of the air duct, completing the automatic sponge pasting of the air duct.
