Description

Technical Field

[0001] The invention relates to the technical field of optical film processing, and in particular to a multi-layer optical film processing feeding device capable of preventing deviation. Background Art

[0002] Optical film is a thin layer of material deposited on the surface of optical elements, and its thickness usually ranges from a few nanometers to hundreds of nanometers. These films can be made of one or more materials, and by precisely controlling the thickness and refractive index of each layer of material, specific optical properties can be achieved. Optical films can be used in many fields. Multilayer optical films are composed of multiple films. When preparing multilayer optical films, it is necessary to feed the multilayer optical films, and the multilayer optical films are prone to displacement.

[0003] In the existing patent CN220283004U, a multi-layer optical film processing feeding device for preventing deviation is disclosed, which relates to the technical field of multi-layer optical film processing, including a base, and support columns are arranged on both ends of the left and right ends of the back side of the base; an inner cavity is arranged inside the base, and a plurality of rollers are arranged in a rectangular distribution between the inner walls of the inner cavity, and L-shaped limit plates are arranged on the front and rear sides of the top of the base, and the limit plates are arranged on both sides of the rollers. The utility model facilitates the transportation and feeding of optical films and improves the processing efficiency through the setting of rollers. Under the setting of limit plates, the optical film in transportation is limited and fixed to avoid the deviation of the optical film, which affects the processing results and improves the processing efficiency.

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] Embodiment 1:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, a multilayer optical film processing feeding device for preventing deviation of the present invention comprises a workbench 1, on which a conveying roller 2 connected to a driving source is installed, support plates 3 are arranged at both ends of the workbench 1, on which a touch component 4 in contact with the optical film is arranged, on which a buffer component 5 is arranged, and on which an energy absorbing component 6 connected to the buffer component 5 is arranged; on the workbench 1, an adjusting component 7 in contact with the optical film is arranged, on the workbench 1, a lifting component 8 located above the adjusting component 7 is arranged, on the workbench 1, a connecting component 9 is arranged between the output end of the lifting component 8 and the adjusting component 7, on the touch component 4, an amplifying component 10 is arranged, between the amplifying component 10 and the lifting component 8, and on the adjusting component 7, a resetting component 12 is arranged; wherein, when the optical film deviates to one side and the optical film just contacts the touch component 4 to generate a force, the lifting component 8 forces one of the transmission components 11 to connect.

[0033] Working principle: The device is installed between two conveying rollers 2 and at the feed port where the deviation is easy to occur. When the multi-layer optical film is processed and fed, the optical film will deviate. Due to the deviation of the optical film, the optical film is forced to come into contact with the instant touch component 4. First, the optical film will exert a force on the instant touch component 4, but the instant touch component 4 does not move. At this time, the lifting component 8 moves, forcing the connecting component 9 on the corresponding side to move, so that the connecting component 9 connects the adjustment component 7 and the lifting component 8 to form a whole. At the same time, the transmission component 11 on the corresponding side is engaged, and the transmission component 11 on the other side is separated, completing the preparation work; when the optical film deviates to the outside, the optical film will exert a force on the instant touch component 4, forcing the instant touch component 4 to move. Through the action of the amplifying component 10, the force of the instant touch component 4 is amplified to a reasonable state, the amplifying component 10 drives the transmission component 11 to rotate, and the transmission component 11 drives the lifting component 8 to move, and the lifting component 8 is lifted. The lowering component 8 drives the connecting component 9 to rotate, and the connecting component 9 drives the adjusting component 7 to rotate to a reasonable angle, and the adjusting component 7 drives the resetting component 12 to move to a reasonable position, so that the adjusting component 7 drives the optical film to produce feedback adjustment, forcing the optical film to return to a normal state. Under the action of the resetting component 12 itself, the adjusting component 7 returns to its original state, and the adjusting component 7 reversely drives the connecting components 9, the transmission components 11, the amplifying components 10 and the instant touch components 4 on both sides to return to their original states, thereby forcing the optical film to resume normal feeding; in summary, a multi-layer optical film processing and feeding device for preventing offset in the present application can realize the function of feedback adjusting the optical film according to the self-movement of the optical film when conveying the optical film feed, thereby realizing the effect of dynamic adjustment, improving the adaptability of the device, facilitating the rapid and timely adjustment of the optical film, reducing the offset degree of the optical film, and improving the anti-offset function of the device, thereby improving the processing efficiency of the optical film.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a multi-layer optical film processing feeding device for preventing deviation of the present invention, the transmission component 11 includes an arc-shaped rack 1101 arranged at both ends of a rotating connecting ring 804, the two arc-shaped racks 1101 are located at different heights on the rotating connecting ring 804, the center of the arc-shaped rack 1101 is located on the axis of the rotating shaft 701, and a transmission gear 1102 meshing with the arc-shaped rack 1101 is fixedly sleeved on the shaft 1002.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a multi-layer optical film processing feeding device for preventing deviation of the present invention, the reset component 12 includes a fixed plate 1201 arranged on the workbench 1, a slide bar 1202 is arranged on the fixed plate 1201, the slide bar 1202 passes through the fixed plate 1201, a limit plate 1203 is arranged at the end of the slide bar 1202, a reset spring 1204 sleeved on the outer ring of the slide bar 1202 is arranged between the limit plate 1203 and the fixed plate 1201, a spur rack 1205 is arranged on the slide bar 1202, and a rotating gear 1206 meshing with the spur rack 1205 is fixedly sleeved on the rotating shaft 701.

[0044] Working principle: The device is installed between two conveying rollers 2 and at the feed port where deviation is likely to occur. The optical film is wound around the two conveying rollers 2 and the adjusting roller 703 in sequence. The driving source is started to force the conveying roller 2 to convey the optical film. In the normal state, the adjusting roller 703 conveys the optical film.

[0045] When the multi-layer optical film is processed and fed, the optical film will deviate. As the optical film deviates outward, the optical film is forced to contact the contact plate 403. The optical film and the contact plate 403 can be designed to be in a just-contact state. As the deviation of the optical film will generate a force on the contact plate 403, the contact plate 403 has a tendency to move but does not move in the initial state. At this time, the control system controls the electric push rod 802 to move, forcing the output end of the electric push rod 802 on the side corresponding to the deviation to move, driving the support rod 803 and the rotating connecting ring 804 to move, so that the corresponding arc-shaped rack 1101 is meshed with the transmission gear 1102, and the square plug 902 is inserted into the L-shaped rod 901. At the same time, due to the inconsistent heights of the two arc-shaped racks 1101, the arc-shaped rack 1101 on the other side is separated from the transmission gear 1102, but the square plug 902 on the other side is inserted into the L-shaped rod 901 on the other side, completing the preparation work;

[0046] When the optical film deviates outward, the optical film will generate a force on the contact plate 403 and cause the contact plate 403 to move. Taking the clockwise rotation of the contact plate 403 as an example, the contact plate 403 moves toward the inner side of one end of the U-shaped block 401, causing the contact plate 403 to rotate clockwise. At this time, the rotating rod 402 rotates, and at the same time, the contact plate 403 drives the baffle plate 504 to generate a force, forcing the baffle plate 504 to drive the buffer rod 503 to move, forcing the buffer rod 503 to drive the piston 502 to move, and the piston 502 squeezes the gas in the buffer cylinder 501, and the buffer spring 505 is compressed, forcing the gas in the buffer cylinder 501 to enter the gas storage cylinder 601 through the intake pipe 602, while the buffer spring 505 at the other end of the U-shaped block 401 is stretched, and the buffer rod 503 slides out of the buffer cylinder 501, realizing the energy absorption effect on the buffer spring 505, and preventing the buffer spring 505 from rebounding and generating a rebound force on the optical film.

[0047] The clockwise rotation of the rotating rod 402 will drive the driving gear 1001 to rotate, and the driving gear 1001 rotates to drive the driven gear 1003 to rotate counterclockwise, forcing the shaft 1002 to rotate counterclockwise. The shaft 1002 rotates to drive the transmission gear 1102 to rotate counterclockwise. The transmission gear 1102 drives the arc rack 1101 to rotate clockwise to a reasonable angle. The arc rack 1101 drives the rotating connecting ring 804 to rotate clockwise. The rotating connecting ring 804 drives the arc rack 1101 on the other side to rotate. Since the arc rack 1101 on the other side is separated from the transmission gear 1102 on the other side, the amplifying component 10 and the instant touch component 4 on the other side do not act.

[0048] Since the square plug rods 902 on both sides are inserted into the L-shaped rod 901, the rotating connecting ring 804 will drive the two L-shaped rods 901 to rotate clockwise, forcing the L-shaped rod 901 to drive the rotating block 702 to rotate, and the rotating block 702 drives the adjusting roller 703 and the rotating shaft 701 to rotate. At the same time, the rotating block 702 drives the rotating shaft 701 and the rotating gear 1206 to rotate clockwise, forcing the rotating gear 1206 to drive the spur rack 1205 to move, the spur rack 1205 drives the sliding rod 1202 to move, and the sliding rod 1202 drives the limiting plate 1203 to move. Under the action of the fixed plate 1201 and the limiting plate 1203, the reset spring 1204 is compressed, and the adjusting roller 703 drives the optical film to adjust. Since the optical film is offset to the outside, when the adjusting roller 703 rotates clockwise, a feedback effect is formed, which will adjust the optical film to the inside to a normal state.

[0049] When the optical film returns to a normal state, since the reset spring 1204 needs to return to its original state, the sliding rod 1202 and the spur rack 1205 return to their original positions, thereby returning the rotating gear 1206 and the rotating shaft 701 to their original positions, the rotating shaft 701 drives the rotating block 702 to rotate to its original position, the rotating block 702 drives the L-shaped rod 901 and the square plug rod 902 to their original positions, thereby returning the arc-shaped racks 1101 on both sides to their original positions, the arc-shaped racks 1101 drive the transmission gear 1102 to its original position, the transmission gear 1102 drives the shaft 1002 and the driven gear 1003 to their original positions, forcing the driving gear 1001 to return to its original position, thereby returning the rotating rod 402 to its original position, the rotating rod 402 forces the contact plate 403 to return to its original position, thereby returning the buffer assembly 5 and the energy absorption assembly 6 on both sides of the U-shaped block 401 to their original positions, completing the reset movement, and forming a feedback reset effect;

[0050] When the adjusting roller 703 rotates to form a feedback effect on the optical film, the optical film is forced to adjust inward to a normal state, thereby forcing the optical film to resume normal feeding, thereby completing the adjustment of the offset of the optical film.

[0051] That is, the setting of the touch component 4 can realize the reaction effect on the optical film, can realize the acquisition of the information of the displacement of the optical film, and at the same time drive the amplification component 10 to move, so as to realize feedback adjustment, and at the same time force the buffer component 5 and the energy absorption component 6 to move, which is beneficial to the protection of the optical film; the setting of the buffer component 5 can realize the buffering effect on the contact plate 403, forcing the contact plate 403 to reduce the movement amplitude of the contact plate 403 when it moves, avoiding the contact plate 403 from moving quickly, resulting in damage to the optical film, and improving the rationality of the device. The buffer components 5 are set on both sides of the U-shaped block 401 to improve the stability of the device; The setting of the energy-absorbing component 6 can absorb the energy of the buffer component 5, reduce the rebound force of the buffer spring 505, and make the gas flow rate entering the gas storage cylinder 601 greater than the gas flow rate out of the gas storage cylinder 601, which can not only effectively consume the energy of the buffer spring 505, but also improve the stability; the setting of the adjustment component 7 can adjust the optical film and realize feedback adjustment. When the optical film deviates to the outside, the adjustment roller 703 will adjust the optical film to the inside, so that the optical film can be normally transported and fed, and at the same time, it can drive the reset component 12 to move; the setting of the lifting component 8 can realize the support rod 8 03 and the height adjustment of the rotating connecting ring 804, so as to realize the meshing of the arc-shaped rack 1101 with the transmission gear 1102 on the corresponding side, improve the rationality of the device, and at the same time adjust the connecting component 9 to realize the connection between the adjusting component 7 and the rotating connecting ring 804; the setting of the connecting component 9 can realize the connection between the square plug rod 902 and the L-shaped rod 901, thereby realizing the adjustment of the rotating block 702, thereby realizing the adjustment of the adjusting component 7, and the setting of the square plug rod 902 can improve the stability of the device, which is convenient for the square plug rod 902 to drive the L-shaped rod 901 to move; the setting of the amplifying component 10 can realize the rotation of the rotating rod 4 02's rotating force amplifies the force to a reasonable state, thereby realizing the regulating effect on the regulating component 7; the setting of the transmission component 11 can make the transmission gear 1102 on the corresponding side mesh with the arc-shaped rack 1101 when the optical film is offset, while the transmission gear 1102 on the other side is separated from the arc-shaped rack 1101, thereby improving the rationality of the device; the setting of the reset component 12 can realize the reset function of the device, thereby forming feedback motion regulation, so that each component returns to its original state, which is beneficial to the feedback effect on the next deflection of the optical film and is beneficial to the regulation of the optical film.

[0052] When conveying the optical film feed, this scheme can realize the function of feedback adjusting the optical film according to the self-movement of the optical film, thereby realizing the effect of dynamic adjustment, improving the adaptability of the device, facilitating the rapid and timely adjustment of the optical film, reducing the degree of deviation of the optical film, and improving the anti-drift function of the device, thereby improving the processing efficiency of the optical film; on the one hand, the device can realize the feedback adjustment effect on the optical film, and on the other hand, the reset component 12 can be used to form a motion feedback adjustment effect on each component, so that the device returns to its original position. Through two feedback adjustments, the movement of the device forms a closed loop, thereby improving the reusability of the device; each component is distributed on both sides of the device, which greatly improves the stability.
