Description

Technical Field

[0001] This application relates to the field of film application device technology, and in particular to a film application roller structure and film application device. Background Technology

[0002] Currently, film is typically applied to cover plates using rollers. During the application process, the rollers apply balanced force to the contact surface of the film, thus pressing the film onto the cover plate.

[0003] With the introduction of 3D curved cover plates, when applying film at the R-corner position of the curved cover plate, the radius r of the roller needs to be less than the R-corner of the curved surface of the cover plate so that the roller can press the film onto the cover plate during application. If the radius r of the roller is greater than the R-corner of the curved surface of the cover plate, the roller cannot press the film onto the R-corner position of the curved surface, resulting in air bubbles in the film at the R-corner position of the curved surface.

[0004] However, when the radius (R) of the 3D curved cover plate is less than 3mm, the radius (r) of the roller must also be less than 3mm. In this case, because the radius (r) of the roller is too small, the roller is very easy to deform when pressure is applied during the application process, which leads to uneven stress on the film material, poor adhesion, and the formation of air bubbles.

[0034] like Figures 1 to 5 As shown, according to a first aspect of the present invention, a film-applying roller structure is provided, which includes a roller 1 and a support 2.

[0035] In the following description, reference will be made to Figures 1 to 5 The specific structure of the above-mentioned components and their connection relationships are described in detail.

[0036] like Figures 1 to 5 As shown, in this embodiment, the roller 1 is pivotally mounted on the first end of the bracket 2 (which can be, for example,...). Figure 1 (As shown at the lower end). Roller 1 is used to attach the membrane material to the cover plate by means of pressure rollers. The second end of the bracket 2 (can be as shown) Figure 1 The upper end (as shown) is mounted on the drive assembly 4 of the film-applying device, enabling the drive assembly 4 to drive the support 2 to move, which in turn drives the roller 1 to press the film material. Preferably, the first side of the roller 1 protrudes from the support 2 for pressing the film material. The support 2 has an abutment surface 20 on the second side of the roller 1. When the roller 1 deforms during the pressing process, the abutment surface 20 of the support 2 can support the roller 1 to avoid uneven stress on the film material due to roller 1 deformation. This effectively avoids the problem of roller 1 easily deforming during the film-applying process when the radius of roller 1 is less than 3mm.

[0037] Preferred, such as Figures 1 to 4As shown, in this embodiment, a gap 10 can be provided between the roller 1 and the contact surface 20 of the bracket 2 to avoid severe friction between the roller 1 and the contact surface 20 during rolling. When the deformation of the roller 1 exceeds a preset range, the second side of the roller 1 will abut against the contact surface 20. Thereafter, since the contact surface 20 can support the roller 1, further deformation of the roller 1 can be prevented, ensuring the flatness of the roller 1 and the platform during the film application process. Further, preferably, the size of the gap 10 is a first dimension 11, where the first dimension 11 > 0 mm and ≤ 1 mm. With this setting, the support effect of the contact surface 20 on the roller 1 is better.

[0038] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the film-applying roller structure may further include two connectors 3. The two connectors 3 may be respectively disposed at both ends of the roller 1 along its axial direction, and the connectors 3 are used to pivotally mount the roller 1 to the first end of the bracket 2. Specifically, the lower end of the connector 3 may be pivotally connected to the end of the roller 1, and the upper end of the connector 3 may be connected to the first end of the bracket 2.

[0039] Furthermore, preferably, such as Figures 1 to 3 As shown, in this embodiment, the lower end of the connector 3 can be a circular plate portion 31. The roller 1 can be coaxially arranged with the circular plate portion 31, and the diameter of the circular plate portion 31 can be larger than the diameter of the roller 1. The axial end of the roller 1 can be pivotally connected to the circular plate portion 31; specifically, the roller 1 and the circular plate portion 31 can be connected via a shaft and a bearing. The upper end of the connector 3 is formed as a connecting plate portion 32, which contacts the end of the bracket 2. The connecting plate portion 32 can be provided with screw holes 33, and the number of screw holes 33 can be multiple, arranged vertically. Correspondingly, the end of the bracket 2 can be provided with corresponding screw holes, and the connecting plate portion 32 and the end of the connector 3 can be connected by screws, thereby pivotally mounting the roller 1 to the bracket 2.

[0040] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the cross-sectional area of ​​the support 2 can gradually increase from the first end to the second end of the support 2. This results in a larger cross-sectional area at the end of the support 2 connected to the drive assembly 4 and a smaller cross-sectional area at the end of the support 2 connected to the roller 1. This configuration improves the structural strength of the support 2 and prevents deformation of the support 2 during the pressing process of the film material.

[0041] Preferred, such as Figures 1 to 4As shown, in this embodiment, the first end of the support 2 may also be provided with a clearance groove 23 for avoiding the cover plate, and the clearance groove 23 is disposed above the roller 1. The clearance groove 23 can extend along the axial direction of the roller 1, and the clearance groove 23 is formed as an arc-shaped recess in the cross-section of the support 2. This arrangement can prevent the first end of the support 2 from interfering with the cover plate during the pressing of the film material.

[0042] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the first end of the support 2 also has a mounting groove 21 extending axially along the roller 1. The mounting groove 21 can be located at the bottom of the first end of the support 2. The abutment surface 20 is the bottom surface of the mounting groove 21, that is, the roller 1 can abut against the bottom surface of the mounting groove 21 when it deforms. During the process of pressing the film material, the first side of the roller 1 (which can be as follows) Figure 4 The lower side shown can contact the membrane material, and the second side of roller 1 (can be as shown) Figure 4 The upper side (as shown) is located within the mounting groove 21. Preferably, the area of ​​the first side of the roller 1 can be larger than the area of ​​the second side of the roller 1.

[0043] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the abutment surface 20 (i.e., the bottom surface of the mounting groove 21) can be an arc surface to fit against the outer surface of the roller 1. Further, preferably, the abutment surface 20 can be parallel to the outer surface of the roller 1, so that when the abutment surface 20 supports the roller 1, the force on the roller 1 can be more uniform, so as to ensure that the film material can be subjected to more uniform force during the pressing process.

[0044] Preferred, such as Figure 4 As shown, in this embodiment, the circumferential end of the mounting groove 21 may also be provided with a rounded chamfer 22, that is, the bottom surface of the mounting groove 21 is connected to the outer surface of the bracket 2 by an arc. This arrangement can prevent the circumferential end of the mounting groove 21 from scratching the surface of the roller 1 when the contact surface 20 supports the roller 1.

[0045] In addition, such as Figure 5 As shown, according to a second aspect of the present invention, a film-applying device is provided, the film-applying device including a driving assembly 4, a device body 5, and a film-applying roller structure as described above. The film-applying roller structure can be mounted on the driving assembly 4. The driving assembly 4 is mounted on the device body 5. The device body 5 is further provided with an attachment surface 50 for placing a cover plate, and the film-applying roller structure can be disposed above the attachment surface 50. The driving assembly 4 is capable of driving the film-applying roller structure relative to the attachment surface 50 along a first direction (which can be as follows). Figure 5 The roller 1 moves vertically (as shown) to apply pressure to the membrane material. The axial direction of roller 1 can be a second direction (such as...). Figure 5(As shown in the horizontal direction), the first direction is perpendicular to the second direction.

[0046] Furthermore, preferably, such as Figure 5 As shown, in this embodiment, the driving assembly 4 may include two slide rails 41, two sliders 42, and a slide table 43. The two slide rails 41 may be respectively disposed on both sides of the attachment surface 50 in a second direction. The two slide rails 41 may extend along a first direction. The two sliders 42 are movably mounted on the two slide rails 41. The two ends of the slide table 43 in the second direction may be respectively connected to the two sliders 42, allowing the slide table 43 to slide along the first direction. The second end of the support 2 may be mounted on the slide table 43, enabling the slide table 43 to drive the support 2 to slide along the first direction, thereby pressing the film material.

[0047] During use, the first side of roller 1 protrudes from the bracket 2 for pressing the film material. The bracket 2 has an abutment surface 20 on the second side of roller 1. When roller 1 deforms during the pressing process, the abutment surface 20 of the bracket 2 supports roller 1, preventing uneven stress on the film material due to roller 1 deformation. This effectively avoids the problem of roller 1 easily deforming during film application when its radius is less than 3mm.
