Description

Technical Field

[0001] This utility model relates to the field of optical film correction technology, and more specifically, to a correction device for optical film production. Background Technology

[0002] In the production process of optical films, the slitting step is one of the key steps to ensure the final size and quality of the product. In traditional technology, optical films need to be transported over a long distance by a series of conveyor rollers before slitting for subsequent processing. However, due to design limitations of the conveying system itself, differences in material properties, and the influence of external environmental factors, the optical film is prone to positional shift during transport. This shift not only leads to a decrease in the dimensional accuracy of the optical film during slitting, resulting in excessive dimensional deviations, but may also cause more serious production failures, such as film breakage and uneven slitting edges, directly affecting product quality and production efficiency. Therefore, we have made improvements and proposed a correction device for optical film production. Summary of the Invention

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As described in the background art, due to the design limitations of the conveying system itself, the differences in material properties, and the influence of external environmental factors, optical films are prone to positional shifts during the conveying process. This shift not only leads to a decrease in the dimensional accuracy of the optical film during slitting and causes excessive dimensional deviations, but may also cause more serious production failures, such as film breakage and uneven slitting edges, directly affecting product quality and production efficiency.

[0020] To solve this technical problem, this utility model provides a correction device for optical film production, which is used for correction during optical film transportation.

[0021] For details, please refer to Figures 1-4 The optical film production correction device specifically includes: The drive mechanism 1 includes a base 108, on which a drive component is mounted. The drive component is connected to two slides 104. A pusher 202 is fixedly connected to the top of each slide 104. Several support rollers 201 are interleaved between the two pushers 202. A support frame 2 is connected between the two ends of the support rollers 201 via bearings. The support frame 2 is mounted on the top of the base 108. A detection mechanism 3 is mounted on one side of the drive mechanism 1. The detection mechanism 3 includes two correction sensors 304.

[0022] The optical film production correction device provided by this utility model can detect whether the optical film is misaligned by using a correction sensor 304. The drive unit can drive the slide table 104 and the pusher 202 to move. During the movement of the pusher 202, the optical film can be moved to correct the misalignment when the optical film is misaligned, thereby improving the dimensional accuracy of the optical film during slitting. The support frame 2 can support the support roller 201, which in turn supports the optical film.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figures 1-4 An optical film production correction device includes a drive mechanism 1, which includes a base 108. A drive component is mounted on the base 108, and the drive component is connected to two slides 104. A pusher 202 is fixedly connected to the top of each slide 104. A plurality of support rollers 201 are interleaved between the two pushers 202. A support frame 2 is connected between the two ends of the support rollers 201 via bearings. The support frame 2 is mounted on the top of the base 108. A detection mechanism 3 is provided on one side of the drive mechanism 1. The detection mechanism 3 includes two correction sensors 304. This application can detect whether the optical film is misaligned by using the correction sensors 304. The drive component can drive the slides 104 and the pushers 202 to move. During the movement of the pushers 202, the optical film can be moved to correct the optical film when it is misaligned, thereby improving the dimensional accuracy of the optical film during slitting. The support frame 2 can support the support rollers 201, which in turn support the optical film.

[0027] Furthermore, such as Figure 4 As shown, a number of first limiting rollers 203 are installed inside the pusher 202. The first limiting rollers 203 are located above the support roller 201 and are parallel to each other. The first limiting rollers 203 are used to cooperate with the support roller 201 to limit the optical film.

[0028] Furthermore, such as Figure 4As shown, a second limiting roller 204 is installed inside the pusher 202. The second limiting roller 204 is perpendicular to the support roller 201 and the first limiting roller 203. The second limiting roller 204, the support roller 201 and the first limiting roller 203 cooperate with each other to isolate the optical film so as to prevent friction between the optical film and the pusher 202.

[0029] Example 2 further optimizes the optical film production correction device provided in Example 1, specifically, as follows: Figures 1-2 As shown, the driving component includes four support seats 101 installed in the base 108. Two adjusting screws 102 are connected between the four bases 108 by bearings. The ends of the two adjusting screws 102 that are far apart from each other are connected to motors 103. The outer surfaces of the two adjusting screws 102 are threadedly connected to two slides 104 respectively. The motors 103 can drive the adjusting screws 102 to rotate. During the rotation of the adjusting screws 102, they can drive the slides 104 to move, thereby driving the pusher 202 to move and thus adjusting the position of the optical film.

[0030] Furthermore, a limiting component is provided between the top of the base 108 and the slide 104. The limiting component can limit the slide 104 to improve the stability of the slide 104 movement.

[0031] Furthermore, such as Figure 2 As shown, the limiting component includes two guide rails 106 mounted on the top of the base 108. A slide block 105 is slidably connected to the top of the guide rails 106. The slide block 105 is mounted on the bottom of the slide table 104. The guide rails 106 and the slide block 105 cooperate with each other to support and limit the slide table 104, thereby improving the stability of the slide table 104 movement.

[0032] Example 3 further optimizes the optical film production correction device provided in Example 1 or 2. Specifically, the correction sensor 304 is used to detect whether the optical film is misaligned.

[0033] Furthermore, such as Figure 1 As shown, the detection mechanism 3 also includes an adjustment component installed on the side of the base 108. Both correction sensors 304 are installed on the adjustment component. The distance between the two correction sensors 304 can be adjusted by the adjustment component, thereby meeting the usage requirements of optical films of different widths.

[0034] Furthermore, such as Figure 1As shown, the adjusting component includes two fixed seats 301 mounted on the side of the base 108. A bidirectional lead screw 302 is connected between the two fixed seats 301 via a bearing. Two connecting brackets 303 are threaded onto the outer surface of the bidirectional lead screw 302. The two connecting brackets 303 are respectively connected to two correction sensors 304. By rotating the bidirectional lead screw 302, the two connecting brackets 303 can be moved closer or further apart, thereby adjusting the distance between the two correction sensors 304.

[0035] Furthermore, such as Figure 1 As shown, the side of the connecting frame 303 is slidably connected to the base 108. This arrangement can limit the movement of the connecting frame 303 to improve the stability of the movement of the correction sensor 304.

[0036] The usage process of the optical film production correction device provided by this utility model is as follows: Rotating the bidirectional lead screw 302 causes the two connecting frames 303 to move closer or further apart. The distance between the two correction sensors 304 is adjusted according to the actual situation. The optical film passes over the top of the support roller 201, while the side of the optical film passes between the first limiting roller 203 and the second limiting roller 204. If the correction sensor 304 detects that the optical film is misaligned, the motor 103 drives the adjusting lead screw 102 to rotate to adjust the movement of the slide table 104. The slide table 104 drives the pusher 202 to move, and the pusher 202 pushes the optical film to move, thereby achieving the correction of the optical film.
