Technical Field

[0001] The utility model relates to a film applying tool, in particular to a film applying tool suitable for assisting in applying a protective film or a decorative film to an edge of a vehicle body, such as a door frame. Background Art

[0002] In recent years, with the development of the automotive industry, the requirements for vehicle design and appearance have become increasingly stringent. For example, the application of decorative films such as black film to various parts of the vehicle has become one of the main ways to enhance the appearance of vehicles due to its advantages such as low cost, good environmental performance, convenient application operation and high production efficiency.

[0003] Currently, the application of applying decorative films such as black films to car doors is already very mature. However, the frames of car doors usually have different heights (also known as widths). There is still a lack of suitable tools for applying decorative films to the frames of car doors. If manual operation is somewhat difficult and positioning is inaccurate, bubbles and wrinkles are easily generated when applying the film, resulting in quality defects.

[0004] In addition to the automotive industry, other industries also use decorative films to modify the surface of objects. For the border parts of the object surface, especially those with different heights, matching film application tools are also required to improve the efficiency and quality of film application.

[0005] Therefore, there is an urgent need for a film applying tool that can be used for film application operations on frame parts of objects with different heights or widths, such as decorative film application on vehicle door frames, to improve film application efficiency and quality and meet the needs of performing effective film application operations.

[0016] It should be noted that the following embodiments are exemplary illustrations of the present invention, and features in different embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0017] Figures 1 to 5 FIG. 1 is a schematic diagram of a film application tool 100 according to an embodiment of the present invention. Figures 1 to 5As shown, the film applying tool 100 includes a first positioning unit 10, a second positioning unit 20 and a film installation unit 30, wherein the film installation unit 30 is connected to the second positioning unit 20, and the first positioning unit 10 and the second positioning unit 20 are configured to drive the film installation unit 30 to move along the surface to be filmed, and the distance between the first positioning unit 10 and the second positioning unit 20 is adjustable.

[0018] The first positioning unit 10 and the second positioning unit 20 are connected by a connecting unit 40, and the length of the connecting unit 40 between the first positioning unit 10 and the second positioning unit 20 is adjustable. Figure 1 As shown, the connecting unit 40 includes two first springs 41. The first ends of the first springs 41 abut against the first positioning unit 10, and the second ends of the first springs 41 abut against the second positioning unit 20. As the first springs 41 are compressed or stretched, the length of the connecting unit 40 between the first positioning unit 10 and the second positioning unit 20 is adjusted accordingly.

[0019] Preferably, the connecting unit 40 further includes two support rods 42, and each first spring 41 is sleeved on a corresponding support rod 42. It is understood that in certain states, the first end of the first spring 41 can abut against the first positioning unit 10, and the second end of the first spring 41 can abut against the second positioning unit 20.

[0020] Preferably, if Figure 5 As shown, the first positioning unit 10 is provided with two holes 15. The holes 15 extend through the first positioning unit 10, namely, from one end of the first positioning unit 10 facing the second positioning unit 20 to the opposite end. Alternatively, the holes 15 may extend partially through the first positioning unit 10, namely, from one end of the first positioning unit 10 facing the second positioning unit 20 to a portion spaced a certain distance from the opposite end. One end of a support rod 42 is disposed within the hole 15 and is movable within the hole 42. The connecting unit 40 also includes two second springs (not shown). One second spring is disposed within each hole 42, distal from the end of the second positioning unit 20, and serves to press the support rod 42 against the hole 42. Under the action of an external force, the support rod 42 moves outward or inward along the hole 42, compressing or stretching the first spring 41 and stretching or compressing the second spring. Thus, the length of the connecting unit 40 between the first positioning unit 10 and the second positioning unit 20 is adjustable.

[0021] It is understandable that the connecting unit 40 may include one or more first springs 41 , one or more support rods 42 , one or more holes 42 and one or more second springs, and the specific number depends on needs.

[0022] The first positioning unit 10 includes a first base 11, a first rolling wheel 12 mounted on the first base 11, and a positioning wheel 13. The positioning wheel 13 is configured as a wheel surface and is configured to contact and roll along the edge of the surface adjacent to the surface to be filmed. The first base 11 is provided with through-holes 16 extending through its upper and lower surfaces. The positioning wheel 13 is fixed to the first base 11, for example, by means of bolts and nuts engaging through-holes 16, facing the surface adjacent to the surface to be filmed.

[0023] The first rolling wheel 12 is configured as a wheel surface and is configured to roll on a surface adjacent to the surface to be coated, and to roll in a direction parallel to the length of the surface to be coated. Optionally, a hole (not shown) is provided on the side of the first base 11 facing the second base 21, and the first rolling wheel 12 is fixed to the first base 11 by, for example, bolts and nuts fitting into the hole. Figure 2 In the illustrated embodiment, two first rolling wheels 12 are provided. It is understandable that in different embodiments, one or more first rolling wheels 12 may be provided as required.

[0024] The second positioning unit 20 includes a second base 21 and a second rolling wheel 22. Figure 5 In the embodiment shown, the second base 21 is composed of a first base structure 21a and a second base structure 21b. Figure 5 As shown, the first base structure 21a can be T-shaped, and the second base structure 21b has a stepped recess to accommodate the lower portion of the T-shaped structure. The first base structure 21a and the second base structure 21b are connected together by screw holes and bolts. In different embodiments, the second base 21 can also be integrally formed.

[0025] like Figure 5 As shown, two holes 25 are provided in the first base structure 21a. The holes 25 extend from one end of the first base structure 21a facing the first positioning unit 10 to a location a certain distance from the other end of the first base structure 21a. The other end of the support rod 42 is disposed within the hole 25 and can be optionally fixed or removably disposed within the hole 25. Similarly, the hole 25 can also be said to contain a spring.

[0026] The second rolling wheel 22 is configured as a wheel surface and is configured to roll on a surface adjacent to the surface to be coated, and to roll in a direction parallel to the length of the surface to be coated. Optionally, holes (not shown) are provided on both sides of the second base structure 21b of the second base 21 facing the first base 11, and the second rolling wheel 22 is fixed to the second base structure 21b of the second base 21 by, for example, bolts and nuts fitting into the holes. Figure 2In the illustrated embodiment, two second rolling wheels 22 are provided. It is understandable that in different embodiments, one or more second rolling wheels 22 may be provided as required.

[0027] Preferably, one or more magnetic elements (not shown) are mounted on the second base 21, and the magnetic elements are configured to adsorb the second base 21 on a surface adjacent to the surface to be filmed. Preferably, one or more pits 23 are provided on the second base 21, and the magnetic elements are respectively disposed in the pits 23. Figure 3 In the embodiment shown, three recesses 23 are provided for accommodating magnetic elements respectively.

[0028] Membrane installation unit 30, such as Figure 3 and Figure 5 As shown, it includes a first roller 31 and a membrane separation element 33. The first roller 31 is configured to rotate about an axis to drive the membrane 60 to move, and the membrane separation element 33 is configured to separate the functional layer 61 and the release layer 62 of the membrane 60. The membrane separation element 33 and the first roller 31 are respectively connected to the second positioning unit 20 in a roughly parallel manner, specifically, connected to the end surface of the second positioning unit 20 away from the first positioning unit 10. Figure 5 In the illustrated embodiment, the second base structure 21 b is connected to the second positioning unit 20 .

[0029] like Figure 5 As shown, the first roller 31 includes a bearing 31a, a sleeve 31b, and a foam cylinder 31c. The bearing 31a and sleeve 31b cooperate to allow the sleeve 31b to rotate about the bearing 31a, thereby allowing the first roller 31 to rotate about its axis. The foam cylinder 31c is sleeved on the sleeve 31b, allowing the first roller 31 to maintain tension on the film 60 and increase friction between them, thereby driving the film 60 during use.

[0030] Optionally, the film installation unit 30 further includes a second roller 32, which is rotatable about an axis and has a smaller diameter than the first roller 31. Similar to the first roller 31, the second roller 32 includes a bearing 32a and a sleeve 32b, and optionally, may also include a foam cylinder (not shown).

[0031] The film installation unit 30 further includes a stop plate 35 , and the first roller 31 and the second roller 32 are arranged in parallel between the stop plate 35 and the second base 21 (specifically, the second base structure 21 b of the second base 21 ), and are fixed on the stop plate 35 and the second base 21 .

[0032] like Figure 3As shown, the membrane separation element 33 includes a blade structure 331 and a base structure 332. The blade structure 331 and the base structure 332 can be integrally formed or connected together. A screw hole 333 can be provided on the base structure 332 to fix the membrane separation element 33 on the second base 21 by means of bolts. The blade structure 331 can be, for example, a "V"-shaped structure, with the tip of the "V"-shaped structure facing the first roller 31 and having a certain distance between it and the first roller 31. Figure 3 As shown, during use, the film 60 covers a portion of the upper surface of the first roller 31. The functional layer 61 of the film 60 passes through the space between the blade structure 331 and the first roller 31, then wraps around a portion of the lower surface of the first roller 31 and is pushed in a direction opposite to the film 60. The release layer 62 covers the upper surfaces of the blade structure 331 and the base structure 332, and is then pushed in a direction parallel to the film 60. Therefore, during the film application operation, the functional layer 61 and the release layer 62 of the film 60 are separated by the membrane separation element 33.

[0033] like Figure 1 、 Figure 3 and Figure 5 As shown, the film mounting unit 30 further includes a press structure 34. The press structure 34 is positioned above the first roller 31 and the second roller 32 (if present), with a space between the press structure 34 and the upper surface of the first roller 31 allowing the film to pass through the space. The space between the upper surface of the first roller 31 and the press structure 34 allows the film 60 to be smoothly clamped. The press structure 34 is rotatably mounted on the second base 21 (second base structure 21b) of the second positioning unit 20 via an axis structure 36 within a certain angular range.

[0034] The pressing structure 34 includes a first sheet structure 341 that is generally L-shaped, comprising a vertical sheet and a horizontal sheet. The lower center of the L-shaped vertical sheet is hollowed out, and each side of the lower portion has a screw hole. The pressing structure 34 may also include a second sheet structure 342, the upper surface of which is laminated to the lower surface of the first sheet structure 341, for example, connected by bolts and nuts. The lower surface area of ​​the second sheet structure 342 is smaller than the upper surface area, and the side surfaces are inclined. This ensures that the lower surface is approximately located above the gap between the first roller 31 and the second roller 32, thereby better clamping the film 60.

[0035] The shaft structure 36 includes a pin 361, two vertical support plates 362 fixed to the upper surface of the second base 21 (second base structure 21b), and a torsion spring 363. The support plates 362 are each provided with a screw hole, and the torsion spring 363 is mounted on the pin 361. The pin 361 passes through the screw holes of the vertical support plates 362 and the screw holes of the pressing plate structure 34 and is fixed to the support plate 362. Thus, the shaft structure 36 allows the pressing plate structure 34 to be rotatably positioned within a certain angle range on the second base 21 of the second positioning unit 20. Thus, before using the film applicator 100, force can be applied to the first sheet structure 341 to slightly move the pressing plate structure 34 away from the first roller 31, thereby facilitating the winding of the film 60 onto the film mounting unit 30. The first sheet structure 341 is then released, thereby clamping the film between the first sheet structure 341 and the first roller 31.

[0036] Alternatively, if Figure 5 As shown, the film application tool 100 may further include one or more spacers 50, which are positioned between the film installation unit 30 and the second positioning unit 20 as needed to assist in adjusting the film installation position. During the film application operation, the surface to be filmed and the adjacent surface to be filmed are usually not on the same plane, and there is a stepped connecting surface between the two. The height (or width) of this connecting surface varies on different objects. Therefore, spacers 50 can be added as needed to ensure that the film installation unit 30 is aligned with the surface to be filmed.

[0037] Figure 6 and Figure 7 This is a schematic diagram of the film application tool 100 of an embodiment of the present invention when in use. The usage scenario is to use the film application tool 100 to apply a black film to the door frame 70 of a vehicle. The door frame 70 (i.e., the surface to be applied with the film) and the door outer frame surface 80 (i.e., the adjacent surface to be applied with the film) are not on the same plane, and there is a stepped connecting surface 82 between the two. The positioning wheel 13 of the first positioning unit 10 of the film application tool 100 is suspended on the frame 81 of the door outer frame surface 80, and the first rolling wheel 12 of the first positioning unit 10 and the second rolling wheel 22 of the second positioning unit 20 are both in contact with the door outer frame surface 80 and can roll thereon. The film installation unit 30 is attached to the vehicle door frame 70. Apply the film as Figure 3As shown, the film is wound around the first roller 31 and second roller 32 of the film installation unit 30. As the first and second rollers 12 and 22 move forward on the vehicle door outer frame surface 80, the film is automatically separated into a functional layer and a release layer. The functional layer is then pressed onto the vehicle door frame 70 under the first roller 31. Generally, the height of the vehicle door outer frame surface 80 varies. Because the length of the connecting unit 40 between the first and second positioning units 10 and 20 is elastically adjustable, the position of the film installation unit 30 can be automatically adjusted at any time to ensure that it remains on the vehicle door frame 70, completing the entire film application process in one go. This improves film application efficiency and quality, meeting the requirements for efficient film application.
