Description

Technical Field

[0001] This utility model relates to the field of brightness enhancement film processing technology, specifically to a brightness enhancement film anti-bending adsorption device. Background Technology

[0002] In the production and processing of brightness enhancement film, there is a risk of bending during handling, placement, and subsequent processing. As a material with extremely high requirements for flatness and optical performance, bending of brightness enhancement film will not only seriously affect its optical performance, such as causing light scattering and uneven refraction, thus reducing the display effect of display devices, but will also damage the appearance quality of the brightness enhancement film, resulting in a lower product yield.

[0003] Currently, existing brightness enhancement film adsorption devices on the market mainly rely on the suction force generated by the suction holes on the adsorption platform in conjunction with the negative pressure pump to achieve adsorption and fixation of the brightness enhancement film. However, this adsorption method has obvious defects. The adsorption area is relatively limited, and the brightness enhancement film is fixed by relying only on the suction force around the adsorption holes. When dealing with larger-sized brightness enhancement films or those that are soft and easily deformed, it is difficult to provide sufficient adsorption force to ensure that the brightness enhancement film is completely flat and adheres to the adsorption platform. This can easily lead to local bending or warping of the brightness enhancement film during the adsorption process. Utility Model Content

[0004] The purpose of this invention is to provide a light-enhancing film anti-bending adsorption device, which has the advantage of increasing the support area during adsorption and fixation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a light-enhancing film anti-bending adsorption device, comprising a base, an electric cylinder fixedly installed on the top of the base, a support frame fixedly installed at the output end of the electric cylinder, an adsorption platform installed inside the support frame, an adsorption hole opened at the top of the adsorption platform, a connecting pipe connected inside the support frame and at the bottom of the adsorption platform, a negative pressure pump installed at one end of the connecting pipe, and a control valve movably installed on the left side of the negative pressure pump, auxiliary support plates installed on both sides of the support frame at the horizontal position of the adsorption platform, and a pull-out plate telescopically installed on the outside of the auxiliary support plates.

[0006] As a preferred embodiment, limit rods are fixedly installed around the top of the base, and a limit connecting plate is installed through the upper end of the limit rods. The inner side of the limit connecting plate is connected to the outside of the support frame.

[0007] As a preferred embodiment, vertical rods are fixedly installed at both ends of the limiting connecting plate, and an adjusting plate is slidably installed on the outside of the vertical rods. The adjusting plate is connected to the vertical rods via a first knob, and a positioning sensor is fixedly installed on the inner side of the adjusting plate corresponding to the position of the adsorption platform.

[0008] As a preferred embodiment, side slide plates are fixedly installed at both the front and rear ends of the auxiliary support plate, and adjustment grooves are provided on both the front and rear sides of the support frame. One end of the side slide plate extends to the outside of the support frame and is slidably connected to the inside of the adjustment groove through a protrusion. A second knob is also installed on the outside of the inner end of the side slide plate.

[0009] As a preferred embodiment, the auxiliary support plate has a pull-out groove inside, and the pull-out part of the pull-out plate is located inside the pull-out groove and is limited on both sides by sliders.

[0010] As a preferred embodiment, the connection between the adjusting plate and the vertical rod is further provided with a snap-fit ​​frame, which is semi-rectangular in shape and snaps onto the outside of the vertical rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the adsorption holes on the adsorption platform in conjunction with a negative pressure pump to stably adsorb the brightness enhancement film. The auxiliary support plate and pull plate can provide auxiliary support on both sides of the brightness enhancement film, effectively preventing the film from bending. The positioning sensor can accurately detect the position of the brightness enhancement film, improving processing quality. The design of the side slide plate and adjustment groove allows the auxiliary support plate to be flexibly adjusted to adapt to brightness enhancement films of different sizes. The device has a reasonable structure and complete functions, which can effectively prevent the brightness enhancement film from bending during processing, improve the processing quality and production efficiency of the brightness enhancement film.

[0013] 2. This utility model forms a stable frame structure through the limiting vertical rods and limiting connecting plates, which constrain and support the support frame from multiple directions. The limiting vertical rods are evenly distributed around the base, like the pillars of a building, which can effectively distribute the force borne by the support frame and prevent it from tilting or shaking due to uneven force during operation. This greatly enhances the structural stability of the entire device and ensures that the device maintains a reliable working state during long-term operation. During the process of the electric cylinder driving the support frame to move up and down, the limiting vertical rods provide a clear guiding path for the movement of the support frame. The support frame can only move vertically along the direction of the limiting vertical rods, avoiding positional deviation caused by loss of control of the movement direction.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figure 1 As shown, this utility model provides a light-enhancing film anti-bending adsorption device, including a base 1, an electric cylinder 8 fixedly installed on the top of the base 1, a support frame 2 fixedly installed at the output end of the electric cylinder 8, an adsorption platform 3 installed inside the support frame 2, an adsorption hole 4 opened on the top of the adsorption platform 3, a connecting pipe 5 connected to the inside of the support frame 2 and located at the bottom of the adsorption platform 3, a negative pressure pump 6 installed at one end of the connecting pipe 5, and a control valve 7 movably installed on the left side of the negative pressure pump 6, auxiliary support plates 17 installed on both sides of the support frame 2 and located at the horizontal position of the adsorption platform 3, and a pull-out plate 18 telescopically installed on the outside of the auxiliary support plate 17.

[0023] This technical solution utilizes the adsorption holes 4 on the adsorption platform 3 in conjunction with the negative pressure pump 6 to stably adsorb the brightness enhancement film. The auxiliary support plate 17 and the pull plate 18 can provide auxiliary support on both sides of the brightness enhancement film, effectively preventing the film from bending. The positioning sensor 13 can accurately detect the position of the brightness enhancement film, improving processing quality. The design of the side slide plate 16 and the adjustment groove 15 allows the auxiliary support plate 17 to be flexibly adjusted to adapt to brightness enhancement films of different sizes. This device has a reasonable structure and complete functions, effectively preventing the brightness enhancement film from bending during processing and improving the processing quality and production efficiency of the brightness enhancement film.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the base 1 has limit rods 9 fixedly installed around its top. The upper end of the limit rods 9 is installed through a limit connecting plate 10. The inner side of the limit connecting plate 10 is connected to the outside of the support frame 2.

[0026] Adopting such Figure 1 The technical solution shown in the diagram uses the limiting vertical rod 9 and the limiting connecting plate 10 to form a stable frame structure, which constrains and supports the support frame 2 from multiple directions. The limiting vertical rod 9 is evenly distributed around the base 1, like the pillars of a building, which can effectively disperse the force borne by the support frame 2 and prevent it from tilting or shaking due to uneven force during operation. This greatly enhances the structural stability of the entire device and ensures that the device maintains a reliable working state during long-term operation. During the process of the electric cylinder 8 driving the support frame 2 to move up and down, the limiting vertical rod 9 provides a clear guiding path for the movement of the support frame 2. The support frame 2 can only move vertically along the direction of the limiting vertical rod 9, avoiding positional deviation caused by loss of control of the movement direction.

[0027] Secondly, in the technical solution, vertical rods 11 are fixedly installed at both ends of the limiting connecting plate 10. An adjusting plate 12 is slidably installed on the outside of the vertical rods 11. The adjusting plate 12 and the vertical rods 11 are connected by a first knob 14. A positioning sensor 13 is fixedly installed on the inner side of the adjusting plate 12 corresponding to the position of the adsorption platform 3. Side slide plates 16 are fixedly installed at both ends of the auxiliary support plate 17. Adjusting grooves 15 are opened on both the front and rear sides of the support frame 2. One end of the side slide plate 16 extends to the outside of the support frame 2 and is slidably connected to the inside of the adjusting groove 15 through a protrusion. A second knob is also installed on the outside of the inner end of the side slide plate 16.

[0028] Its adoption is as follows Figure 1The technical solution shown has an adjusting plate 12 slidably connected to the vertical rod 11 and fixed by a first knob 14, allowing the adjusting plate 12 to be adjusted up and down on the vertical rod 11 according to actual needs. Since a positioning sensor 13 is installed on the inner side of the adjusting plate 12 and corresponds to the position of the adsorption platform 3, this adjustability can adapt to brightness enhancement films of different thicknesses and placement positions, meeting diverse production requirements. The auxiliary support plate 17 is slidably connected to the adjusting groove 15 on the support frame 2 via a side slide plate 16 and fixed by a second knob, allowing the auxiliary support plate 17 to be adjusted in the front and rear directions of the support frame 2. This allows the position of the auxiliary support plate 17 to be flexibly adjusted according to the actual width of the brightness enhancement film, providing a suitable support range for brightness enhancement films of different sizes, effectively preventing the brightness enhancement film from bending during processing, and enhancing the adaptability of the device to brightness enhancement films of different specifications.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-4 As shown, the auxiliary support plate 17 has a pull-out groove inside, the pull-out part of the pull-out plate 18 is located inside the pull-out groove and is limited by sliders on both sides; the connection part between the adjustment plate 12 and the vertical rod 11 is also equipped with a snap-fit ​​frame, and the snap-fit ​​frame is set in a semi-rectangular shape and is snapped on the outside of the vertical rod 11.

[0031] With the above technical solution, a pull-out groove is opened inside the auxiliary support plate 17, and the pull-out part of the pull-out plate 18 is in the groove and limited by a slider. This design allows the pull-out plate 18 to extend and retract flexibly within the auxiliary support plate 17. In actual use, the pull-out plate 18 can be pulled out or pushed in according to the specific width of the brightness enhancement film, thereby adjusting the width of the auxiliary support plate 17 and providing more fitting and effective support for brightness enhancement films of different widths. This further enhances the device's ability to protect the brightness enhancement film from bending and improves the device's versatility and practicality. The pull-out plate 18 is limited by sliders on both sides, effectively preventing the pull-out plate 18 from shaking, shifting, or falling out of the pull-out groove during the pulling process. The cooperation between the slider and the pull-out groove makes the movement of the pull-out plate 18 more stable and smooth, ensuring that the pull-out plate 18 can always maintain a stable position when supporting the brightness enhancement film, providing reliable support for the film.

[0032] The working principle of this utility model is as follows: First, place the device in a suitable working position and turn on the power. According to the size of the brightness enhancement film, adjust the position of the side slide plate 16 in the adjustment groove 15 so that the auxiliary support plate 17 and the pull plate 18 adapt to the width of the brightness enhancement film. Then, adjust the support frame 2 to a suitable height by using the electric cylinder 8 and place the brightness enhancement film on the adsorption platform 3. Next, turn on the negative pressure pump 6 and adjust the appropriate suction force by using the control valve 7 so that the brightness enhancement film is firmly adsorbed onto the adsorption platform 3 through the adsorption hole 4. At the same time, according to the thickness of the brightness enhancement film, adjust the positioning sensor 13 to a suitable position by sliding the adjustment plate 12 on the vertical rod 11 to detect and position the position of the brightness enhancement film. During the entire processing, the auxiliary support plate 17 and the pull plate 18 support both sides of the brightness enhancement film to prevent the brightness enhancement film from bending. After processing is completed, turn off the negative pressure pump 6, remove the brightness enhancement film, and complete one operation.
