Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology for automotive interiors, and in particular to a release paper covering structure for the adhesive area during laser cutting of automotive interiors. Background Technology

[0002] In the modern manufacturing process of automotive interior parts, laser cutting technology has become the mainstream processing technology for key components such as dashboards, door panels, and center consoles due to its significant advantages such as non-contact processing, high cutting precision, and high processing efficiency. However, when the laser-cut area involves a pre-coated adhesive layer, how to effectively protect the adhesive layer in the non-cut areas becomes a critical technological challenge that urgently needs to be solved. This is mainly because: on the one hand, the high temperature generated during laser cutting can easily cause the surrounding adhesive layer to melt and splatter, which not only contaminates the workpiece surface but also affects the subsequent assembly quality; on the other hand, modern automotive interior parts generally adopt complex curved surface designs, making it difficult for traditional protection processes to achieve a tight fit. In addition, as the automotive industry continues to raise its requirements for the appearance quality of interior parts, it has put forward more stringent standards for adhesive area protection technology, and existing processes are no longer able to meet these new manufacturing needs. However, existing release paper covering structures for adhesive areas in laser-cut automotive interior parts still have problems such as the inability to automatically cover the adhesive area, inaccurate release paper positioning, and weak release paper adhesion.

[0003] Therefore, it is essential to invent a release paper covering structure for the adhesive area during laser cutting of automotive interior trim. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a release paper covering structure for the adhesive area during laser cutting of automotive interior trim, solving the problems of existing release paper covering structures for the adhesive area during laser cutting of automotive interior trim, such as inability to automatically cover the adhesive area, inaccurate release paper positioning, and poor release paper adhesion. The release paper covering structure for the adhesive area during laser cutting of automotive interior trim includes support legs, a support frame, a pressing zone, a feeding belt, a drive motor, automotive interior trim parts, a covering structure, and release paper. The pressing zone is installed at the unloading end of the support frame, and the support legs are fixedly installed below the support frame and the pressing zone. The feeding belt is disposed inside the support frame and the pressing zone. The drive motor is fixedly installed on the outside of the support frame and engages with the feeding belt. The automotive interior trim parts are placed on the surface of the feeding belt, and the covering structure is fixedly installed on the outside of the support frame. The release paper is suspended below the covering structure.

[0005] The pressing area includes a supporting shell, an extension frame, a rotating shaft, and a pressing structure. The supporting shell is installed at the unloading end of the supporting frame, and the extension frame is fixedly installed on the outside of the supporting shell. The rotating shaft is rotatably installed on the inside of the top of the extension frame, and the pressing structure is wrapped around the outside of the rotating shaft.

[0006] The covering structure includes a support frame, a base plate, a pressure push rod, a connecting frame, a transmission frame, and a release paper cutter. The support frame is fixedly installed on the outside of the support frame, and the base plate is fixedly installed on the top of the support frame. The pressure push rod is fixedly installed on the surface of the base plate, and the connecting frame is fixedly installed on the top of the pressure push rod. The transmission frame is fixedly installed below the connecting frame and extends downward through the base plate. The release paper cutter is fixedly installed at the bottom of the transmission frame.

[0007] The pressing structure inside the pressing area uses a cylindrical silicone airbag, and the pressing structure can be rotated by the drive of the rotating shaft. The pressing structure will deform after being pressed; the pressing structure can deform and fit the entire surface of the automotive interior parts after contacting them; the rotating shaft is connected to an external motor through a gear shaft.

[0008] The release paper cutter inside the cover structure is a steel metal box, and the bottom surface of the release paper cutter is provided with a ring-shaped metal blade of a specific shape. The release paper cutter is equipped with a heating wire inside. The heating wire inside the release paper cutter can heat the metal blade at its bottom. The release paper cutter can be driven to move back and forth in the vertical direction by a pressure push rod. When moving downward, the release paper cutter can cut off a piece of the release paper inside the release paper through the metal blade at its bottom, and push the release paper to the surface of the automotive interior parts through the downward thrust.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The design of the pressing zone in this invention ensures a tight fit between the release paper and the adhesive area of ​​the automotive interior parts. Its core function is to utilize the adaptive deformation characteristics of the silicone airbag-type pressing structure to achieve adaptive pressing of curved surfaces under the drive of a rotating shaft. This not only applies pressure evenly to avoid air bubbles but also protects the material from damage. This structure can work in conjunction with a covering structure to first achieve precise cutting and positioning of the release paper, and then ensure a firm bond through rolling pressing. This provides reliable adhesive area protection for subsequent laser cutting processes and adapts to interior parts with different curved surfaces, significantly improving production yield and efficiency.

[0010] This invention features a cover structure for the precise cutting and automatic pressing of release paper. It achieves melting and cutting via a heated annular metal blade beneath the release paper cutter head, ensuring a clean cut. A pressure pusher then precisely presses the cut release paper block onto the adhesive area of ​​the automotive interior parts, integrating cutting and pressing into a single process. This structure not only avoids the errors of traditional manual application but also adapts to adhesive areas of varying shapes, ensuring reliable protection of non-processed areas during laser cutting, while simultaneously improving production efficiency and process consistency.
