Description

Technical Field

[0001] This utility model relates to a masking tape. Background Technology

[0002] Vehicles, such as electric vehicles, typically require painting on their body surfaces to create decorative and / or protective films. A major trend in the electric vehicle industry today is the diversification and uniqueness of vehicle exterior design. For example, a certain part of the vehicle body (such as the waistline or dividing line) may be painted a different color than the rest to achieve a multi-colored appearance.

[0003] To achieve the above objectives, different areas of the vehicle body need to be painted in separate colors during the painting process. Before painting, masking tape needs to be applied to both sides of the surface to be painted to cover areas that do not need to be painted, preventing paint splattering onto these areas. However, when the surface to be painted is a long stretch (e.g., a long dividing line or trim strip), using traditional masking tape presents several inconveniences.

[0004] In the prior art, when masking tape is applied to both sides of a long surface to be painted, the masking tape on both sides of the surface to be painted is not easy to align, resulting in uneven spacing between the tapes on both sides. This makes it impossible to guarantee the flatness of the surface to be painted (i.e., the dividing line or decorative strip), which in turn affects the efficiency and quality of the painting operation.

[0005] Therefore, the industry urgently needs a solution that can effectively address the problems and / or defects in existing technologies when painting long-distance surfaces. Utility Model Content

[0006] The purpose of this utility model is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0007] According to one aspect of the present invention, a masking tape is provided for assisting in color separation painting of a long distance of surface to be painted during a painting operation on the surface of a vehicle. The masking tape includes: a tape layer and a protective film layer. The tape layer has a perforated area matching the shape of the long distance of surface to be painted, the perforated area penetrating the tape layer in the thickness direction; the protective film layer is attached to the tape layer and at least covers the tape layer including the perforated area, wherein the surface of the protective film layer facing the tape layer is adhesive.

[0008] In an exemplary embodiment of the present invention, the hollowed-out area extends continuously along the length direction of the tape layer.

[0009] In an exemplary embodiment of the present invention, the hollowed-out area extends through the tape layer along its length.

[0010] In an exemplary embodiment of the present invention, the hollowed-out areas have uniform spacing in the width direction of the tape layer.

[0011] In an exemplary embodiment of the present invention, the tape layer includes one or more of the hollowed-out areas.

[0012] In one exemplary embodiment of the present invention, the masking tape is presented in the form of being wound into a roll.

[0013] In an exemplary embodiment of the present invention, the masking tape is a single-sided tape.

[0014] In an exemplary embodiment of the present invention, the release force of the protective film layer facing the adhesive tape layer is less than the release force of the adhesive tape layer.

[0015] In an exemplary embodiment of the present invention, the masking tape further includes a release paper layer, which is attached to the tape layer from the other side of the tape layer and covers the cut-out area.

[0016] According to the masking tape provided in the foregoing embodiments of this utility model, by setting a hollow area in the tape layer that matches the shape of the long-distance surface to be painted, precise masking of the long-distance surface to be painted is achieved. When performing color-separation painting operations on the long-distance surface to be painted of vehicles, it can effectively solve the problems of the existing masking tape being difficult to align and uneven spacing, thereby ensuring the flatness of the surface to be painted and improving the efficiency and quality of the painting operation.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0023] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0024] Figure 1 This is a three-dimensional diagram showing a vehicle with a dividing painted area on its body. (Example) Figure 1 As shown, the vehicle is a small electric car. The side surface of this small electric car has a dividing line painted area T extending from the front to the rear. This area is painted a different color than the rest of the side surface, thus achieving the desired two-tone appearance. Of course, besides… Figure 1 The dividing line painting area T shown in the diagram can also refer to other color-separated painting areas such as door and window perimeters that require painting operations on small electric vehicles. In this invention, these dividing line painting areas or color-separated painting areas on the vehicle body surface can be referred to as long-distance surfaces to be painted before the painting operation. The masking tape provided in this invention is mainly used for masking areas... Figure 1 In the painting operation of a vehicle, exemplified by a small electric vehicle, a color-separation painting operation, taking a dividing line as an example, is used to assist in performing such an operation on a long surface to be painted.

[0025] Figure 2 This is a schematic diagram showing the structure of the masking tape 1 according to an exemplary embodiment of the present invention, illustrating the basic structure and shape of the masking tape 1. Figure 3 This is an enlarged cross-sectional view showing the masking tape 1 according to an exemplary embodiment of the present invention, clearly illustrating the relative positional relationships of the constituent layers in the masking tape 1. For example... Figure 2 As shown, the masking tape 1 is a single-sided tape, usually presented in a rolled form for easy storage. Along the unfolding direction of the masking tape 1, the masking tape 1 can be continuously unfolded to form a long, thin strip structure. According to this utility model, as... Figure 3As shown, the masking tape 1 includes a tape layer 10. The tape layer 10 provides basic masking and adhesion functions. The tape layer 10 is provided with a cutout area 11, the shape of which can be designed according to the shape of the long-distance surface to be painted, so that it matches the shape of the long-distance surface to be painted. For example, the width of the cutout area 11 can be specifically designed according to the width of the long-distance surface to be painted. According to an exemplary embodiment of the present invention, as Figure 2 and Figure 3 As shown, the hollowed-out area 11 is along the length of the tape layer 10 ( Figure 2 The perforated area 11 extends continuously along the length of the tape layer 10 (in the left-right direction). Specifically, the perforated area 11 extends continuously through the tape layer 10 along its length, and simultaneously extends along the thickness of the tape layer 10 (in the left-right direction). Figure 3 The tape layer 10 is penetrated in the vertical direction to form a through-type open area. In addition, the open area 11 has a uniform spacing in the width direction of the tape layer 10.

[0026] According to the present invention, the tape layer 10 may include one or more cutout areas 11. In the illustrated exemplary embodiment, the tape layer 10 includes only one cutout area 11. In other alternative embodiments, the tape layer 10 may include multiple cutout areas arranged at a desired spacing along the width direction of the tape layer 10. The arrangement of multiple cutout areas 11, for example, allows the use of a single masking tape 1 to assist in the simultaneous formation of color separation painting operations for multiple dividing lines. According to the present invention, in an exemplary embodiment, the cutout areas 11 in the tape layer 10 have a uniform width along the length direction of the tape layer 10. However, in other alternative embodiments, the cutout areas 11 may be designed with a shape having a gradually changing width, i.e., the width of the cutout areas 11 gradually changes along the length direction of the tape layer 10. Masking tape 1 with this design is particularly suitable for color separation painting operations on surfaces to be painted with conical or wedge-shaped features (e.g., trim strips on the front and rear bumpers of a car or trim areas around door handles). Furthermore, the cutout area 11 can be designed in different geometric shapes to suit various application requirements. For example, the cutout area 11 can be rectangular, circular, elliptical, or irregular in shape to facilitate color-separation painting of decorative strips, marking areas, or other feature parts of different shapes on the surface of vehicles. Additionally, the cutout area 11 can also be designed in a wavy or serrated shape to accommodate surface features with complex contours. This diverse cutout area design allows the masking tape 1 to be applied to a wider range of painting applications.

[0027] According to this utility model, such as Figure 3As shown, the masking tape 1 also includes a protective film layer 20. The protective film layer 20 is attached to the tape layer 10, at least covering the tape layer 10 including the cutout area 11, to provide structural support and protection for the tape layer 10 and its cutout area 11. The width and / or length of the tape layer 10 generally matches the width and / or length of the protective film layer 20. The surface of the protective film layer 20 facing the tape layer 10 is adhesive, allowing it to adhere firmly to the tape layer 10. Naturally, the release force of the surface of the protective film layer 20 facing the tape layer 10 is less than the release force of the tape layer 10. In the illustrated exemplary embodiment, the protective film layer 20 is a transparent PET layer, allowing the operator to observe the position of the underlying tape layer 10 and the cutout area 11 through the protective film layer 20, facilitating precise positioning and alignment. In other alternative embodiments, the protective film layer 20 may be constructed of different materials to provide specific functional characteristics. For example, in some alternative embodiments, the protective film layer 20 may be made of a material with a special color, such as blue or green, to provide visual contrast and help operators more easily identify the boundary between the masked area and the area to be painted. In other alternative embodiments, the protective film layer 20 itself may be pre-printed with graduations, alignment marks, or other auxiliary markings to help operators make accurate positioning and measurements. When the masking tape is stored in roll form, the protective film layer 20 also serves as release liner. Except for the core area, the inner and outer surfaces of the masking tape are peelably adhered to the protective film layer 20, thereby providing protection and support for the masking tape and reducing the amount of additional release liner required.

[0028] According to this invention, masking tapes 1 with different widths can be designed to meet different masking requirements. Wider tapes are suitable for masking, for example, thin, long-distance dividing lines, while wider tapes are suitable for masking, for example, thick, long-distance dividing lines.

[0029] Alternatively, the masking tape 1 may also include a release paper layer (not shown), which can be attached to the tape layer 10 from the side opposite to where the protective film layer 20 is located, and covers the cutout area 11. The release paper layer provides additional protection for the masking tape 1, particularly during storage and transportation, preventing the adhesive surface of the tape layer 10 from accidentally adhering to other objects. In practical use, the operator can remove the release paper layer as needed to expose the adhesive surface of the tape layer 10.

[0030] Figure 4 This shows the application of masking tape 1 to surface S of a vehicle. For example... Figure 4As shown, masking tape 1 is unfolded and laid on the surface S of the vehicle. As the masking tape 1 is gradually unfolded along its length, the operator can lay it on the surface S of the vehicle according to actual needs. This allows the masking tape 1 to effectively cover surfaces that do not need to be painted while exposing the target surface to be painted through the cutout area 11. The design of the masking tape 1 provided by this utility model enables operators to quickly and accurately mask long surfaces to be painted, achieving precise color separation painting effects. It effectively solves the problems of uneven alignment and spacing of existing masking tapes, thereby ensuring the flatness of the surface to be painted and improving the efficiency and quality of the painting operation.

[0031] It should be noted that, in addition to the small electric vehicles described above, the term "vehicle" mentioned herein can also refer to other small vehicles, buses, or train carriages. In other words, the masking tape provided by this invention can also be applied to the surfaces of these vehicles to assist in performing color-separation painting operations on their surfaces.

[0032] Although the present invention has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of the present invention and should not be construed as a limitation thereof.

[0033] While some embodiments of the present invention have been shown and described, those skilled in the art will understand that changes may 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.
