Description

Technical Field

[0001] The utility model relates to the technical field of glass film laminating technology, in particular to a rolling film laminating clamp for curved glass. Background Art

[0002] After curved glass is processed, a film often needs to be applied to its surface to prevent scratches and protect it. Because curved glass surfaces have a certain curvature, common glass film application equipment or tools are primarily designed for applying film to flat glass and are not suitable for curved glass. Therefore, the industry currently relies on manually applying the film to the curved glass surface, then cutting the film with a laser or a sharp tool to ensure that the film is even at the edges to complete the film application. This process requires manual leveling and rolling to remove bubbles from the glass surface before cutting. Depending on the operator's skill level and the size of the film, the film can adhere unevenly to the glass surface, and wrinkles and bubbles can easily form at the application site, affecting the film application effect. Furthermore, due to tolerance fluctuations in product manufacturing, both laser cutting and manual cutting can easily damage the product surface, resulting in a poor appearance. Furthermore, manual cutting or laser cutting is difficult to achieve when the film size is smaller than the product surface size, making these film application methods limited in their applicability.

[0036] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] The utility model discloses a curved glass rolling film laminating fixture 10 which is suitable for laminating small-sized films and is suitable for laminating large curved glass that is bent in a single direction. Figure 1-7 The curved glass rolling film laminating fixture 10 of this embodiment includes a sliding base 100, a positioning base 200 and a rolling assembly 300. The upper surface of the sliding base 100 is provided with a positioning installation area 110 and a sliding installation area 120 located next to the positioning installation area 110. The sliding installation area 120 is provided with a first sliding limit portion 130 extending toward the positioning installation area 110. The first sliding limit portion 130 is used to limit the moving path of the rolling assembly 300. The positioning base 200 is located within the positioning and mounting area 110 and is fixedly connected to the sliding base 100. The upper surface of the positioning base 200 is provided with a product receiving area 210 and a plurality of first adsorption holes 220 within the product receiving area 210. The shape of the product receiving area 210 is adapted to the shape of the curved glass to be coated, so that the curved glass is fully attached to the product receiving area 210. This prevents the curved glass from being compressed and cracked due to hollowing between the curved glass and the upper surface of the positioning plate when squeezed by the rubber roller, thereby reducing the defective rate during the curved glass coating process. The positioning base 200 is provided with a first vacuum air duct connected to each first adsorption hole 220. The first vacuum air duct runs through the side of the positioning base 200 and forms a first air inlet 230 connected to an external vacuum device. That is to say, when the curved glass to be filmed is placed in the product receiving position 210 of the positioning base 200, the curved glass is fixed on the positioning base 200 by vacuum adsorption to achieve the positioning of the curved glass and prevent the curved glass from shifting during the film-painting process, thereby ensuring the film-painting effect.

[0038] The roller assembly 300 includes a slide 310, a film suction fixing plate 320 hingedly connected to the upper end of the slide 310 and rotatable relative to the slide 310, a rubber roller 330 located on the film suction fixing plate 320 on a side away from the slide 310 and rotatably connected to the film suction fixing plate 320, and a film material suction plate 340 fixed on the film suction fixing plate 320 adjacent to the positioning base 200. The lower portion of the slide 310 is provided with a second sliding limit portion 311 that slidably limits the first sliding limit portion 130. A film material mounting position 341 and a plurality of second suction holes 342 located in the film material mounting position 341 are provided on the surface of the film material suction plate 340. A second vacuum air duct is provided in the film material suction plate 340 that is connected to each second suction hole 342. The second vacuum air duct passes through the side of the film material suction plate 340 and forms a second air inlet that is connected to an external vacuum device. The second air inlet is provided with an air pipe interface 343 that is connected to the external vacuum device. Similarly, after the film is placed in the film mounting position 341, it is fixed to the film suction plate 340 through vacuum suction. This prevents the film from falling off the film suction plate 340 as the film suction plate 340 rotates with the film fixing plate 320. This also prevents the film from shifting relative to the curved glass during the film application process, thereby ensuring a satisfactory film application. In this embodiment, the first sliding stop 130 and the second sliding stop 311 cooperate to guide and position the slide 310, ensuring smooth sliding of the rolling assembly 300. This prevents the film from shifting relative to the curved glass during the application process, allowing the film to fully cover the area to be applied to the curved glass surface. When the film suction fixing plate 320 is flipped over and the film material suction plate 340 corresponds to the upper surface of the positioning base 200, the slide 310 drives the film suction fixing plate 320 to move away from the positioning base 200 under the action of external tension, so that the rubber roller 330 sticks the film material on the film material suction plate 340 to the product surface on the positioning base 200.

[0039] For details, please combine Figure 8-17The film application process for curved glass includes five stages. In the first film application stage, the film suction fixing plate 320 is flipped so that the film material suction plate 340 is located above the film suction fixing plate 320. The film material is then placed in the film material mounting position 341 of the film material suction plate 340. The second air inlet of the film material suction plate 340 is connected to an external vacuum device, generating negative pressure at the second suction holes 342. This creates a negative pressure suction zone at the film material mounting position 341, which forces the film material to adhere tightly to the surface of the film material suction plate 340 under the action of the negative pressure. During this stage, the edge of the film material contacts the rubber roller 330. In the second film application stage, the film suction fixing plate 320 is flipped so that the film material suction plate 340 is located below the film suction fixing plate 320. The slide 310 is pulled toward the positioning base 200 until the rubber roller 330 contacts the edge of the positioning base 200 away from the slide 310. During the third and fourth film laminating stages, the rubber roller 330 is pressed against the surface of the curved glass. Since the rubber roller 330 is still in contact with the edge of the film material, the rubber roller 330 simultaneously presses the edge of the film material against the surface of the curved glass during the process of pressing the rubber roller 330 against the surface of the curved glass. At this time, the film material suction plate 340 is continuously connected to the external vacuum device to maintain vacuum adsorption of the film material. The slide 310 is then pulled away from the positioning base 200. During this process, as the rubber roller 330 compresses the film, the film gradually leaves the surface of the film suction plate 340 and adheres to the curved glass surface. The film is simultaneously compressed by the rubber roller 330 and vacuumed by the film suction plate 340, causing the film to be tensioned. This allows the film to be smoothly pulled off the film suction plate 340 as it rolls along the surface of the curved glass, preventing wrinkles during lamination. Furthermore, as the rubber roller 330 rolls against the curved glass surface, it maintains line contact with the surface, ensuring a smooth and even roll of the film onto the product surface, preventing bubbles. In the fifth lamination stage, the rubber roller 330 completely leaves the curved glass surface, at which point the film is completely free of the film suction plate 340 and firmly adheres to the product surface, completing the film lamination process.

[0040] The above-mentioned curved glass rolling film laminating fixture 10 positions the curved glass to be laminarized and the film material respectively through the positioning base 200 and the film material suction plate 340, so that the film material and the glass are aligned. When the slide 310 is pulled to move, the film material is squeezed by the rubber roller 330 so that the film material is adhered to the glass surface. When the rubber roller 330 squeezes the film material, the curved surface of the curved glass and the fact that the rubber roller 330 can be tangent to the glass surface are used to make the force on the surface of the film material uniform and the force direction perpendicular to the curved surface. The air between the film material and the glass surface can be squeezed out. After laminating, there are no bubbles and wrinkles on the film material on the glass surface, which improves the film laminating effect. The film material can be pre-cut and then laminarized. After laminating, there is no need to use laser or sharp tools to cut the film material, which can avoid the problem of poor product appearance caused by scratching the product surface by laser or sharp tools. It can also be used for film laminating operations when the film material size is smaller than the product surface size, expanding the applicable scenarios of the curved glass rolling film laminating fixture 10.

[0041] The sliding base 100 is used to receive the positioning base 200 and the rolling assembly 300, and to provide a place for applying film to curved glass. Figure 1-3 In this embodiment, the sliding base 100 is a plate-like structure, which can be a rectangular plate-like structure, a circular plate-like structure or other regular polygonal plate-like structure. A groove is provided on the upper surface of the sliding base 100 to form a positioning and mounting area 110. The positioning base 200 is embedded in the groove and fixedly connected to the sliding base 100. In this way, the positioning base 200 can be pre-positioned through the constraint of the inner side of the groove, so that the positioning base 200 can be quickly aligned with the mounting structure on the sliding base 100 to reduce the installation difficulty of the positioning base 200. In one embodiment, a plurality of feet 140 are arranged at intervals on the lower surface of the sliding base 100. Preferably, each foot 140 is evenly arranged on the lower surface of the sliding base 100 and is screwed to the sliding base 100. By arranging the feet 140 on the lower surface of the sliding base 100, the height of the lower surface of the sliding base 100 is raised to avoid water or oil on the work surface splashing onto the upper surface of the sliding base 100, thereby causing product or film material contamination problems.

[0042] Furthermore, at least one support column 150 is provided on the upper surface of the sliding base 100 within the sliding installation area 120 for supporting the film suction fixing plate 320. Preferably, two support columns 150 are provided on the upper surface of the sliding base 100 on opposite sides of the first sliding limit portion 130. By providing the support columns 150 on the sliding base 100, when the film is installed on the film material suction plate 340, the film suction fixing plate 320 is flipped, and the film material suction plate 340 is located above the film suction fixing plate 320. At this time, the lower surface of the film suction fixing plate 320 contacts the top of the support columns 150. That is, the support columns 150 are used to support the film suction fixing plate 320 when the rolling assembly 300 is in a flat state, thereby reducing the difficulty of placing the film on the film material suction plate 340, facilitating the placement and positioning of the film material, and facilitating observation of the surface condition of the film material.

[0043] To achieve sliding engagement between the slide 310 and the sliding base 100, in one embodiment, the first sliding engagement portion 130 is a sliding groove defined on the upper surface of the sliding base 100, and the second sliding engagement portion 311 is a slider disposed on the bottom of the slide 310 and slidably inserted into the sliding groove. The bottom of the slide 310 is raised to form a slider, or the slider is screwed to the bottom of the slide 310. Preferably, two sliding grooves are defined in parallel and spaced apart on the upper surface of the sliding base 100, and two sliders are fixed to the bottom of the slide 310, one corresponding to the two grooves. This increases the sliding engagement area between the slide 310 and the sliding base 100, prevents the slide 310 from shaking during sliding, and thereby improves the sliding stability of the slide 310. In another embodiment, the first sliding engagement portion 130 is a slide rail fixed to the upper surface of the sliding base 100, and the second sliding engagement portion 311 is a limiting groove defined on the lower surface of the slide 310 and slidably engaged with the slide rail. The slide rail is fixed to the upper surface of the sliding base 100 by screws. Preferably, two sliding rails are provided in parallel at intervals on the upper surface of the sliding base 100, and two limiting grooves corresponding to the two sliding rails are provided at the bottom of the slide 310. In this way, the sliding matching area between the slide 310 and the sliding base 100 is increased, and the slide 310 is prevented from shaking during the sliding process, thereby improving the sliding stability of the slide 310.

[0044] Furthermore, a stopper 160 is provided on the upper surface of the sliding base 100 within the sliding mounting area 120 to limit the sliding range of the slide 310. Specifically, a strip-shaped guide hole or slot 101 is formed on the upper surface of the sliding base 100. The strip-shaped guide hole or slot 101 extends in the same direction as the first sliding stopper 130. The stopper 160 is fixedly connected to the sliding base 100 by a screw that penetrates the stopper 160 and is inserted into the strip-shaped guide hole or slot 101. Thus, by adjusting the position of the stopper 160 within the strip-shaped guide hole or slot 101 and locking the stopper 160, the distance between the stopper 160 and the positioning base 200 can be adjusted, thereby adjusting the sliding range of the slide 310 to accommodate film application on curved glass surfaces of varying sizes.

[0045] Please combine Figure 1 as well as Figure 4-5 The positioning base 200 includes a positioning plate 240 and a back sealing plate 250. The upper surface of the positioning plate 240 is provided with a product receiving position 210 and a first adsorption hole 220. The lower surface of the positioning plate 240 is provided with an air guide groove connected to the first adsorption hole 220. The side of the positioning plate 240 is provided with an air guide notch connected to the air guide groove. The back sealing plate 250 is attached to the lower surface of the positioning plate 240 and is sealed with the positioning plate 240. The upper surface of the back sealing plate 250 and the air guide groove together form a first vacuum air duct, and the upper surface of the back sealing plate 250 and the air guide notch together form a first air inlet 230. In this embodiment, the positioning plate 240 is connected to the back sealing plate 250 by screws, and the contact surface between the back sealing plate 250 and the positioning plate 240 is provided with a sealing ring or coated with sealant to avoid air leakage at the first vacuum air duct and the first air inlet 230, so as to prevent the product from loosening and shaking during the film pasting process due to air leakage of the positioning base 200, thereby causing the occurrence of film pasting failure problems, so as to reduce film material waste.

[0046] Furthermore, in this embodiment, the back sealing plate 250 is screwed to the sliding base 100; the back sealing plate 250 is provided with a plurality of first strip holes 251 extending along the length of the back sealing plate 250, and the positioning plate 240 is provided with a plurality of second strip holes 241 corresponding to each of the first strip holes 251. The back sealing plate 250 is fixedly connected to the positioning plate 240 by screws passing through each of the first strip holes 251 and the second strip holes 241. In this embodiment, the extension direction of the first sliding stopper 130 is defined as the Y-axis direction, and the length direction of the back sealing plate 250 is defined as the X-axis direction. In other words, the extension direction of the first sliding stopper 130 is perpendicular to the length direction of the back sealing plate 250. The same explanation can be made for the definition of directions in other embodiments. By opening a first strip hole 251 on the back sealing plate 250 and a second strip hole 241 on the positioning plate 240, when the back sealing plate 250 is fixed on the sliding base 100, the screws connecting the back sealing plate 250 and the positioning plate 240 can be loosened, and the position of the positioning plate 240 can be adjusted along the X-axis direction and then the screws can be tightened. In this way, the position between the curved glass to be filmed and the film material can be adjusted along the X-axis direction so that the film material is aligned with the product. In other embodiments, a positioning adjustment block 170 is provided on each opposite side of the positioning installation area 110, and the connecting line of the two positioning adjustment blocks 170 is parallel to the X-axis direction. An adjusting screw is rotatably passed through the positioning adjustment block 170, and the end of the adjusting screw abuts against the side of the positioning plate 240. In this way, when the positioning plate 240 and the back sealing plate 250 are assembled, there is no need to lock the connecting screws between the positioning plate 240 and the back sealing plate 250. At this time, the position between the positioning plate 240 and the back sealing plate 250 along the X-axis direction is adjustable. At this time, the positioning plate 240 can be pushed to move by rotating the adjusting screw, thereby adjusting the relative displacement between the back sealing plate 250 and the positioning plate 240 along the X-axis direction, thereby reducing the difficulty of adjusting the position of the positioning plate 240.

[0047] In one embodiment, the slide 310 has a U-shaped structure and includes two vertical portions 312 disposed opposite each other and a horizontal portion 313 located between the two vertical portions 312 and fixedly connected to the bottom ends of the two vertical portions 312. By designing the slide 310 as a U-shaped structure, the mating area between the slide 310 and the film suction fixing plate 320 is increased, which helps to improve the stability of the installation of the film suction fixing plate 320. In this embodiment, the rolling assembly 300 also includes a hinge connection mechanism, which includes a rotating pin 350 that rotatably passes through the upper portion of the vertical portion 312, a fixing block 360 located outside the vertical portion 312 and fixedly connected to the rotating pin 350, and the fixing block 360 is screwed to the film suction fixing plate 320. The vertical portion 312 is provided with a rotation hole 314 for receiving the rotating pin 350, and the rotation hole 314 is provided with a first bearing 315 that rotatably cooperates with the rotating pin 350. By providing a first bearing 315 within the rotation hole 314, the resistance to the film suction fixing plate 320's rotation relative to the slide 310 is reduced, allowing the film suction fixing plate 320 to rotate smoothly. Furthermore, two extended fixing buckles 321 are fixed to the film suction fixing plate 320 on the side away from the slide 310. The rubber roller 330 is located between the two extended fixing buckles 321 and is rotationally connected to them. A second bearing 322 is provided at the rotational connection between the rubber roller 330 and the extended fixing buckles 321. In other words, the rubber roller 330 extends along the X-axis and rotates about the X-axis. Providing the second bearing 322 at the rotational connection between the rubber roller 330 and the extended fixing buckles 321 reduces the resistance to the rubber roller 330's rotation relative to the film suction fixing plate 320, allowing the rubber roller 330 to rotate smoothly. At least one pressure-bearing mechanism is provided on the side of the film-absorbing fixing plate 320 away from the carriage 310, corresponding to the middle portion of the rubber roller 330. The pressure-bearing mechanism includes a cantilever 323 fixed to the film-absorbing fixing plate 320 and a third bearing 324 rotatably mounted on the cantilever 323 and abutting the rubber roller 330. The third bearing 324 supports the middle portion of the rubber roller 330. In other words, the third rubber roller 330 effectively serves as a pressure-bearing member for the rubber roller 330. This prevents deformation of the middle portion of the rubber roller 330 due to greater pressure in the middle and less pressure at the ends when the rubber roller 330 is subjected to external pressure, thereby extending the service life of the rubber roller 330. Furthermore, the support provided by the third bearing 324 for the middle portion of the rubber roller 330 also prevents wrinkles and bubbles in the film material during lamination, which could be caused by deformation of the rubber roller 330, thereby ensuring a good lamination effect.

[0048] Furthermore, in one embodiment, at least one handle 325 is fixed to the film suction fixing plate 320 on the side facing away from the film material suction plate 340. Preferably, three handles 325 are evenly spaced along the X-axis on the side of the film suction fixing plate 320 facing away from the film material suction plate 340. The handles 325 are positioned so that they do not interfere with the support column 150.
