Detailed implementation manners
[0024] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The following will describe the present invention in detail with reference to the drawings and in combination with the embodiments.
[0025] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.
[0026] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inside, outside" refers to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present invention.
[0027] In order to solve the problems of film pasting offset and bubbles caused by electrostatic adsorption and damage to the optical waveguide in the existing film pasting device for the optical waveguide, the present invention provides a film pasting device for the optical waveguide.
[0028] Such as Figures 1 to 4As shown in the figure, the film pasting device for the optical waveguide includes a bottom plate 10, a waveguide loading component, a displacement component, and a film supply component 40. The waveguide loading component is arranged on the bottom plate 10. The waveguide loading component includes a loading tray 21 that is movably arranged along the x-axis direction and the y-axis direction. The loading tray 21 is used to place a tray containing the optical waveguide to be pasted with film. The film supply component 40 is located on the side of the waveguide loading component away from the bottom plate 10. The film supply component 40 is movably arranged along the x-axis direction and the z-axis direction through the displacement component. The film supply component 40 at least includes an adsorption structure 42 and an ion air knife scraping and pressing structure 43. The ion air knife scraping and pressing structure 43 is located on the periphery of the adsorption structure 42. The adsorption structure 42 is used to adsorb the film material 52. The ion air knife scraping and pressing structure 43 is used to output ionized air to the surface of the film material 52 away from the optical waveguide, so that the film material 52 adheres to the optical waveguide.
[0029] By providing the bottom plate 10, the bottom plate 10 provides an installation position for the waveguide loading component, the displacement component, and the film supply component 40, which is beneficial to the use reliability of each component. The waveguide loading component includes a loading tray 21 that is movably arranged along the x-axis direction and the y-axis direction. The loading tray 21 is used to place a tray containing the optical waveguide to be pasted with film. This setting enables, during film pasting, the tray containing the optical waveguide to be pasted with film to be placed on the loading tray 21, and through the movement of the loading tray 21 in the x-axis direction and the y-axis direction, the optical waveguide is transported to the film pasting position. By releasing the film material 52 from the film supply component 40 and moving it along the x-axis direction, the film material 52 is gradually moved to the fitting position on the surface of the optical waveguide. The ion air knife scraping and pressing structure 43 is provided, so that during the film pasting process, the ion air knife scraping and pressing structure 43 can output ionized air on the side of the film material 52 away from the optical waveguide and move along the x-axis direction with the film supply component 40. Through the air pressure, the natural fitting of the film material 52 and the surface of the optical waveguide is achieved, thus avoiding the problem of damaging the surface structure of the optical waveguide caused by rigid contacts such as direct contact and pressing. And through the movement of the ionized air, the film material 52 and the surface of the optical waveguide are gradually and slowly fitted. Through the gradual and slow advancement, the adsorption process between the film material 52 and the surface of the optical waveguide is more controllable, effectively preventing the generation of bubble problems during the film pasting process. At the same time, the ionized air can effectively remove the static electricity of the film material 52 during the fitting process, avoiding the risk of film pasting position deviation caused by static electricity adsorption, which is beneficial to improving the film pasting accuracy.
[0030] It should also be noted that the loading tray 21 is used to place a tray containing the optical waveguide to be pasted with film. The purpose of this setting is that if a new optical waveguide needs to be pasted with film, the tray can be directly replaced, which is beneficial for the film pasting device to adapt to different optical waveguides and is beneficial to expanding the scope of application.
[0031] Specifically, the film supply assembly 40 further includes a film storage part 44, a film release part 45, and a film recovery part 46. The film release part 45 is located on the side of the ion air knife scraping and pressing structure 43 facing the bottom plate 10, and the ion air knife scraping and pressing structure 43 is located between the adsorption structure 42 and the film release part 45. The film storage part 44 is used to store the film roll. The film roll includes a base 51 and a plurality of films 52 attached to the base 51. The plurality of films 52 are wound around the film storage part 44 along with the base 51. One end of the film roll passes through the film release part 45 and is connected to the film recovery part 46.
[0032] It should be noted that the plurality of films 52 are arranged at intervals on one side surface of the base 51, that is, any two adjacent films 52 are arranged at intervals. The base 51 is wound in a circular manner, and the plurality of films 52 are wound around the film storage part 44 along with the base 51 to form a film roll. The starting end of the film roll extends from the film storage part 44 and winds around to the side of the film release part 45 away from the ion air knife scraping and pressing structure 43 at the position between the ion air knife scraping and pressing structure 43 and the film release part 45, and then winds around to the film recovery part 46. By setting it in this way, by rotating the film recovery part 46, the movement of the base 51 is driven, so that the films 52 on the base 51 are gradually released from the film release part 45. After one side of the film 52 is released from the film release part 45, it is adsorbed by the adsorption structure 42, and then the ion air output by the ion air knife scraping and pressing structure 43 drags the film 52 to gradually fit with the surface of the optical waveguide along the release direction to complete the film pasting work, ensuring the stability of the film pasting process, being beneficial to avoiding problems such as damage to the surface structure of the optical waveguide caused by rigid contact such as direct contact and pressing, and at the same time being beneficial to eliminating the static electricity of the film 52 and avoiding the problem of film pasting displacement caused by static electricity adsorption.
[0033] It should also be noted that the ion air knife scraping and pressing structure 43 has a strip-shaped blade, and the ion air knife scraping and pressing structure 43 adjusts the air pressure and the acting area through the strip-shaped blade. By arranging the strip-shaped blade in the ion air knife scraping and pressing structure 43, the acting area of the ion air can be effectively controlled, and the linear scraping effect can be realized in cooperation with the displacement assembly and the film release part 45. At the same time, the fitting speed can be controlled by adjusting the air pressure.
[0034] Such as Figure 1As shown, the film storage part 44 includes a first rotating shaft, and the recovery part 46 includes a second rotating shaft. The film roll is wound around the first rotating shaft. One end of the film roll passes around the demolding end of the demolding part 45 and is connected to the second rotating shaft, specifically wound around the second rotating shaft. By rotating the second rotating shaft, the film material 52 extends out of the demolding part 45 along with the movement of the substrate 51. Specifically, the surface of the substrate 51 away from the film material 52 contacts the demolding end of the demolding part 45. After rotating the second rotating shaft, the movement direction of the substrate 51 from the film storage part 44 to the demolding part 45 is different from the movement direction of the substrate 51 from the demolding part 45 to the recovery part 46. Thus, through the contact movement of the substrate 51 on the demolding end of the demolding part 45, the film material 52 gradually detaches from the substrate 51 at the demolding end of the demolding part 45. The part of the film material 52 that detaches from the substrate 51 extends towards the adsorption structure 42 and is then adsorbed by the adsorption structure 42. By attaching the film material 52 to the substrate 51 and setting it as a roll and winding it on the film storage part 44, the film material 52 can be protected from damage and contamination, and the film material 52 can drive the first rotating shaft to rotate along with the rotation of the second rotating shaft as the substrate 51, and then the substrate 51 with the film material 52 is released from the film storage part 44; setting the recovery part 46 to include a second rotating shaft enables the demolded substrate 51 to be wound around the second rotating shaft, thereby realizing the recovery of the substrate 51.
[0035] It should be noted that the film supply assembly 40 further includes a carrier plate 41. The adsorption structure 42, the ion air knife scraping and pressing structure 43, the demolding part 45, the film storage part 44, and the recovery part 46 are all arranged on the carrier plate 41. The film storage part 44 further includes a detachable limiting plate. The limiting plate is annular. One end of the first rotating shaft is rotatably connected to the carrier plate 41, and the other end of the first rotating shaft is connected to the center of the annular limiting plate. By setting the limiting plate, it is beneficial to avoid the risk of the film roll slipping off the first rotating shaft during rotation and is beneficial to ensuring the position stability of the film roll.
[0036] As Figure 1As shown, the film supply assembly 40 further includes a plurality of rotating shafts, which are rotatably arranged on the carrier plate 41. The plurality of rotating shafts are used to carry the substrate 51. At least one rotating shaft is arranged between the film storage part 44 and the demolding part 45, and at least one other rotating shaft is arranged between the demolding part 45 and the recovery part 46. In a specific embodiment of the present application, the plurality of rotating shafts include a third rotating shaft 47, a fourth rotating shaft 48, and a fifth rotating shaft 49. The third rotating shaft 47 is located on the path from the film storage part 44 to the demolding part 45. The fourth rotating shaft 48 and the fifth rotating shaft 49 are arranged at intervals on the path from the demolding part 45 to the recovery part 46. The projections of the third rotating shaft 47, the fourth rotating shaft 48, and the fifth rotating shaft 49 in the x-axis direction are arranged at intervals. The distance from the fifth rotating shaft 49 to the bottom plate 10 in the z-axis direction > the distance from the third rotating shaft 47 to the bottom plate 10 in the z-axis direction > the distance from the fourth rotating shaft 48 to the bottom plate 10 in the z-axis direction. The substrate 51 is carried on the side of the third rotating shaft 47 and the fourth rotating shaft 48 facing the bottom plate 10, and the substrate 51 is carried on the side of the fifth rotating shaft 49 away from the bottom plate 10. Such a setting is beneficial to the rotating shafts to support the substrate 51 by increasing the rotating shafts, which is beneficial to ensuring the flatness of the substrate 51 and further ensuring the movement of the substrate 51.
[0037] Optionally, limit plates can be selectively arranged at the ends of the third rotating shaft 47, the fourth rotating shaft 48, and the fifth rotating shaft 49 away from the carrier plate 41, which can be set according to actual needs. In addition, the number of rotating shafts can also be increased or decreased according to actual situations, not limited to the three in this application.
[0038] As Figure 2 shown, the adsorption structure 42 is arranged at an interval from the demolding part 45. Specifically, the adsorption end of the adsorption structure 42 is arranged at an interval from the demolding end of the demolding part 45, and the adsorption end of the adsorption structure 42 is located in the direction in which the film material 52 exits from the demolding end of the demolding part 45. And the adsorption structure 42 and the demolding part 45 are arranged at an angle. Such a setting enables the part of the film material 52 that exits from the demolding end of the demolding part 45 to extend to the adsorption end of the adsorption structure 42, and then be adsorbed by the adsorption structure 42, realizing the local horizontal adsorption of the film material 52, enabling the film material 52 to achieve horizontal slow fitting, and avoiding the problem of bubbles caused by poor fitting adsorption during the demolding process through cooperation with the ion air knife scraping and pressing structure 43. In addition, the adsorption structure 42 can build an identification model for adsorbing flexible materials in advance, so as to better adsorb the flexible film material 52.
[0039] Combined with Figure 1 and Figure 3As shown, the distance between the adsorption end of the adsorption structure 42 and the bottom plate 10 in the z-axis direction is less than the distance between the air outlet end of the ion air knife scraping and pressing structure 43 and the bottom plate 10 in the z-axis direction. By creating a height difference between the adsorption end of the adsorption structure 42 and the air outlet end of the ion air knife scraping and pressing structure 43, the horizontal line of the air outlet end of the ion air knife scraping and pressing structure 43 is located above the horizontal line of the adsorption end of the adsorption structure 42, which is beneficial for the ion air knife scraping and pressing structure 43 to blow air on the back of the film material 52, thus achieving the natural fitting of the film material 52 to the surface of the optical waveguide.
[0040] As Figure 4 shown, the demolding part 45 is arranged at an angle with the bottom plate 10, and the included angle θ between the demolding part 45 and the bottom plate 10 is greater than or equal to 10° and less than or equal to 30°. By reasonably restricting the included angle between the demolding part 45 and the bottom plate 10, it is beneficial for the demolding of the film material 52, enabling the film material 52 to be more smoothly and gently demolded from the substrate 51 and adsorbed by the adsorption structure 42, thus realizing the slow demolding and release fitting of the film material 52.
[0041] Specifically, the carrier plate 41 is divided into a first area and a second area. The second area is located on the side of the first area away from the bottom plate 10. The adsorption structure 42, the ion air knife scraping and pressing structure 43, and the demolding part 45 are all located in the first area, and the film storage part 44 and the recovery part 46 are both located in the second area. In addition, the third rotating shaft 47 and the fourth rotating shaft 48 are located in the first area, and the fifth rotating shaft 49 is located in the second area. By reasonably planning the positions of each structure on the carrier plate 41, it is beneficial to the stability of the operation of each structure, beneficial to ensuring the reliability of the transportation, demolding of the film material 52, and the recovery of the substrate 51, and beneficial to improving the work efficiency; at the same time, fixing the entire film supply assembly 40 on the carrier plate 41 can fix and support the stable operation of the film supply assembly 40, and can also make each part of the film supply assembly 40 more concentrated, ensuring that the demolding process of the film material 52 can be better completed.
[0042] In an alternative embodiment of the present application, the film supply assembly 40 further includes a handle, and at least one of the film storage part 44 and the recovery part 46 is provided with a handle. Specifically, there is one handle and it is provided on the recovery part 46. By means of the handle, the recovery part 46 is rotated, so that the demolded substrate is wound around the recovery part 46, and at the same time, the film storage part 44 can be rotated along with the recovery part 46, realizing the continuity of the film supply of the film material 52. In another alternative embodiment of the present application, the first rotating shaft and the second rotating shaft can also rotate automatically.
[0043] As Figure 4As shown, the film pasting device further includes a first positioning structure 60 and a second positioning structure 70. The first positioning structure 60 is arranged on the waveguide loading component and is located on one side of the loading tray 21. The first positioning structure 60 is used to identify and position the film material 52 on the film supply component 40. The second positioning structure 70 is arranged on the film supply component 40 and is located on the side of the adsorption structure 42 away from the ion air knife scraping and pressing structure 43. The second positioning structure 70 is used to identify and position the optical waveguide. Specifically, the second positioning structure 70 is arranged on the carrier plate 41.
[0044] During the film pasting process, the first positioning structure 60 can take a photo of the part of the film material 52 extending out of the demolding part 45, so as to realize the identification of the film material 52 and accurately position the position of the film material 52. The second positioning structure 70 can position the optical waveguide placed in the tray during the film pasting process and match the positioning result of the film material 52 by the first positioning structure 60, so as to realize the precise fitting of the optical waveguide and the film material 52, and can meet the film pasting accuracy requirement of 0.1 mm for the optical waveguide.
[0045] It should be noted that during the film pasting process, the film material 52 is partially demolded from the demolding part 45 by the transmission of the substrate 51 and adsorbed by the adsorption structure 42 to establish a visual recognition template, which is convenient for the subsequent precise fitting and positioning of the optical waveguide. When fitting, the adsorbed part of the film material 52 is preferentially released to fit with the optical waveguide, and then the remaining film material 52 is gradually released to fit with the optical waveguide as a whole, so as to realize the slow film pasting of the film material 52 in the x-axis direction.
[0046] As Figure 1 As shown, the waveguide loading component further includes a first guide rail 22 and a second guide rail 23. There are multiple first guide rails 22, and the multiple first guide rails 22 all extend along the y-axis direction, and the multiple first guide rails 22 are arranged at intervals along the x-axis direction. The second guide rail 23 extends along the x-axis direction, and the second guide rail 23 is slidably arranged on the first guide rail 22, and the loading tray 21 is slidably arranged on the second guide rail 23. Such a setting drives the loading tray 21 to move in the y-axis direction by the sliding of the second guide rail 23 on the first guide rail 22, and drives the loading tray 21 to move in the x-axis direction by the sliding of the loading tray 21 on the second guide rail 23, so as to realize the bidirectional movement of the optical waveguide in the x-axis direction and the y-axis direction, and position the optical waveguide in the loading tray 21 by the second positioning structure 70.
[0047] Specifically, the displacement component includes a support frame 31 and a slider 32. The support frame 31 is arranged on the bottom plate 10 and supports above the waveguide loading component. The support frame 31 has a first slideway extending in the x-axis direction. The slider 32 is slidably arranged on the first slideway. The slider 32 has a second slideway extending in the z-axis direction for the film component 40 to be slidably arranged on the second slideway. The support frame 31 can support the film component 40 above the waveguide loading component. Furthermore, the movement of the adsorption structure 42 in the z-axis direction is realized through the movement of the film component 40 on the second slideway, and the movement of the adsorption structure 42 in the x-axis direction is realized through the movement of the slider 32 on the first slideway. The first positioning structure 60 is located on one side of the second guide rail 23. The film material 52 is positioned by moving the adsorption structure 42 to the first positioning structure 60, and then the film material 52 on the adsorption structure 42 is moved to a position corresponding to the optical waveguide. The adsorption structure 42 releases the film material 52, enabling the film material 52 to be partially attached to the optical waveguide. Furthermore, the remaining part of the film material 52 is attached to the optical waveguide through the movement of the adsorption structure 42. During the movement of the adsorption structure 42, the substrate 51 moves on the demolding part 45, causing the film material 52 to separate from the substrate 51. The ion air knife scraping and pressing structure 43 is synchronously started to linearly scrape and defoam the film material 52 during the attachment process, thereby obtaining an optical waveguide with precise attachment and no bubbles.
[0048] It should be noted that the movement of the film component 40 on the second slideway can be controlled by a motor, thereby controlling the distance between the film material 52 and the optical waveguide, which is beneficial to controlling the release degree of the adsorption structure 42 on the film material 52.
