Description

Technical Field

[0001] This utility model relates to the field of film bonding technology, specifically a multi-layer optical film bonding mechanism. Background Technology

[0002] Multilayer optical film lamination mechanisms are specialized equipment used for the precision composite processing of optical film materials, such as in display manufacturing. Displays require the composite of multiple layers of optical films, such as polarizers, brightness enhancement films, and diffusers, to improve the optical performance of display devices.

[0003] Existing composite film lamination mechanisms typically employ single-thread or assembly line lamination. During the lamination process, a slide table is usually used to place the substrate and perform optical film lamination. This prevents personnel from performing other operations during the lamination process. Only after the lamination is completed can personnel load and unload materials, resulting in low production efficiency. To address this, we propose a multi-layer optical film lamination mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a multilayer optical thin film bonding mechanism to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multilayer optical film bonding mechanism, including an operating table;

A drive motor is fixedly connected to the inner wall of the top of the operating table. A rotating rod is fixedly connected to the output end of the drive motor. A sliding sleeve is movably fitted onto the side surface of the rotating rod. A turntable is fixedly connected to the top of the sliding sleeve. A sliding table is movably connected to the side surface of the turntable via a bearing and is slidably connected to the U-shaped slide groove. A placement groove for placing a substrate is fixedly connected to the top of the sliding table.

[0007] A clamping assembly includes a bracket, a fixing member fixedly connected to the top side of the bracket, a cylinder fixedly sleeved inside the fixing member, a slider fixedly connected to the output end of the cylinder, a movable groove opened inside the bracket, the slider slidably connected in the movable groove, a fixing plate fixedly connected to the top of the slider, a connecting tube fixedly sleeved in the slots at the four corners of the fixing plate, a suction cup fixedly connected to the bottom of the connecting tube, and an air pump fixedly connected to the top of the fixing plate.

[0008] Preferably, the top of the operating table is provided with a lifting assembly, the lifting assembly includes a fixed base, the bottom of the fixed base is fixedly connected to one side of the top of the operating table, the top of the fixed base is fixedly connected to a slide rod, and the top of the operating table is fixedly connected to an electric push rod.

[0009] Preferably, one end of the slide rod is slidably connected through the bracket, and the output end of the electric push rod is fixedly connected to the bottom of the bracket.

[0010] Preferably, there are two rotating rods, and the two rotating rods are distributed at a 90-degree angle.

[0011] Preferably, the slide table is limited by a U-shaped slide groove and slides along the U-shaped slide groove, and the slide table is driven by a drive motor and a rotating rod.

[0012] Preferably, the air pump input end is fixedly connected to the top of the connecting pipe through a distributor and a hose, and the slider slides along the movable groove as the output end of the cylinder extends and retracts.

[0013] Preferably, the output end of the electric push rod is extended and retracted to adjust the height of the bracket, and the bracket moves up and down along the slide rod trajectory.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this multilayer optical thin film bonding mechanism,

[0015] By switching the U-shaped chute and two slides of the component, when the substrate is being laminated with optical film, the previously laminated product is transported to the vicinity of the operator, so that the operator can remove the laminated product and place the new substrate. This allows the lamination and loading / unloading to be carried out simultaneously, thereby improving work efficiency. At the same time, the slides and substrates are kept away from the operator during the lamination process, thereby reducing obstacles to the operator's loading and unloading operations and improving production safety.

[0016] The placement slot allows for positional correction of the substrate placed within it, thereby improving the accuracy of film application. Simultaneously, because the slide table slides along the U-shaped groove and the rotation direction of the slide table is restricted by the U-shaped groove, the slide table cannot turn during movement. Thus, when the placement slot at one end of the U-shaped groove moves to the middle of the U-shaped groove, only the horizontal position changes without changing the angle, which is beneficial for the bonding and positioning of the optical film, further improving the film application accuracy and enhancing the stability of the mechanism.

[0023] The technical solutions of the present utility model 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 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.

[0024] This utility model embodiment provides a multilayer optical thin film bonding mechanism, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes an operating console 1;

[0025] Switching component 2 includes a U-shaped slide 201, which is located on the top of the operating table 1. A drive motor 202 is fixedly connected to the inner wall of the top of the operating table 1. A rotating rod 203 is fixedly connected to the output end of the drive motor 202. A sliding sleeve 204 is movably sleeved on the side surface of the rotating rod 203. A turntable 205 is fixedly connected to the top of the sliding sleeve 204. A sliding table 206 is movably connected to the side surface of the turntable 205 through a bearing, and the sliding table 206 is slidably connected to the U-shaped slide 201. A placement groove 207 for placing a substrate is fixedly connected to the top of the sliding table 206.

[0026] The clamping assembly 3 includes a bracket 301. A fixing member 302 is fixedly connected to the top side of the bracket 301. A cylinder 303 is fixedly sleeved inside the fixing member 302. A slider 305 is fixedly connected to the output end of the cylinder 303. A movable groove 304 is opened inside the bracket 301. The slider 305 is slidably connected in the movable groove 304. A fixing plate 306 is fixedly connected to the top of the slider 305. A connecting tube 307 is fixedly sleeved in the slots on the four corners of the fixing plate 306. A suction cup 30 is fixedly connected to the bottom of the connecting tube 307. 8. An air pump 309 is fixedly connected to the top of the fixing plate 306. In use, the substrate is first placed in the placement groove 207, which then positions the substrate. Next, the cylinder 303 is activated, causing its output end to retract, moving the suction cup 308 onto the optical film on the conveyor belt. Then, the electric push rod 403 is activated, causing its output end to retract, lowering the suction cup 308 on the bracket 301 until it contacts the optical film. Finally, the air pump 309 is activated, causing the air pump 309 to... A negative pressure is generated at the input end, causing the suction cup 308 to adhere to the optical film. Then, the output end of the electric push rod 403 extends, lifting the optical film adsorbed on the bracket 301 and the suction cup 308. Next, the output end of the cylinder 303 extends until the slider 305 reaches its limit, at which point the suction cup 308 moves above the placement groove 207, aligning the substrate and the optical film. Then, the output end of the electric push rod 403 retracts and moves downwards, adhering the optical film to the substrate. Finally, the cylinder 303 reverses its pumping action, turning the input end into the output end, thereby allowing… The suction cup 308 releases its adsorption of the optical film, and then the electric push rod 403 lifts the suction cup 308 again. Then the drive motor 202 is started, so that the output end of the drive motor 202 drives the rotating rod 203 to rotate 90 degrees, so that the slide table 206, which was originally located in the middle of the U-shaped slide 201, moves along the U-shaped slide 201 to one end of the U-shaped slide 201. At this time, the bonded product can be removed and a new substrate can be placed. At the same time, the substrate, which was originally located on the slide table 206 at the other end of the U-shaped slide 201, moves to the middle of the U-shaped slide 201 for optical film bonding.

[0027] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the top of the operating table 1 is provided with a lifting assembly 4. The lifting assembly 4 includes a fixed base 401. The bottom of the fixed base 401 is fixedly connected to one side of the top of the operating table 1. The top of the fixed base 401 is fixedly connected to a slide rod 402. The top of the operating table 1 is fixedly connected to an electric push rod 403.

[0028] In embodiments of this utility model, such as Figure 1, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, one end of the slide rod 402 is slidably connected through the bracket 301, and the output end of the electric push rod 403 is fixedly connected to the bottom of the bracket 301.

[0029] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, there are two rotating rods 203, which are distributed at a 90-degree angle. By switching the U-shaped slide 201 of the component 2 and the two slides, when the substrate is being laminated with an optical film, the previously laminated product is transported to the vicinity of the operator, so that the operator can remove the laminated product and place a new substrate. This allows the film lamination and loading / unloading to be carried out simultaneously, thereby improving work efficiency. At the same time, during the lamination process, the slides 206 and the substrate are kept away from the operator, thereby reducing obstacles to the operator's loading and unloading operations and improving production safety.

[0030] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the slide table 206 is limited by the U-shaped slide groove 201 and slides along the U-shaped slide groove 201. The slide table 206 is driven by the drive motor 202 and the rotating rod 203.

[0031] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the input end of the air pump 309 is fixedly connected to the top of the connecting pipe 307 through a distributor and a hose. The slider 305 slides along the movable groove 304 as the output end of the cylinder 303 extends and retracts. The substrate placed in the placement groove 207 can be corrected in position, thereby improving the accuracy of film application. At the same time, since the slide table 206 slides along the U-shaped slide groove 201 and the U-shaped slide groove 201 restricts the rotation direction of the slide table 206, the slide table 206 cannot turn when moving. Therefore, when the placement groove 207 on one end of the U-shaped slide groove 201 moves to the middle of the U-shaped slide groove 201, it only changes the horizontal position without changing the angle, which is beneficial for the bonding and positioning of the optical film, further improving the film application accuracy and the stability of the mechanism.

[0032] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the output end of the electric push rod 403 extends and retracts to adjust the height of the bracket 301, which rises and falls along the trajectory of the slide rod 402.

[0033] Working Principle: In operation, the substrate is first placed in the placement groove 207, which then positions the substrate. Next, the cylinder 303 is activated, causing its output end to retract, moving the suction cup 308 onto the optical film on the conveyor belt. Then, the electric push rod 403 is activated, causing its output end to retract, lowering the suction cup 308 on the bracket 301 until it presses against the optical film. Next, the air pump 309 is activated, creating negative pressure at its input end, allowing the suction cup 308 to adhere to the optical film. The output end of the electric push rod 403 then extends, lifting the optical film adhered to the bracket 301 and suction cup 308. Finally, the output end of the cylinder 303 extends until the slider 305 reaches its limit, at which point the suction cup 308 moves... The device moves to the top of the placement slot 207, at which point the substrate and the optical film are aligned. Then, the output end of the electric push rod 403 retracts and moves downward, allowing the optical film to adhere to the substrate. Next, the cylinder 303 pumps air in reverse, turning the original input end into the output end, thereby releasing the suction cup 308 from adsorption of the optical film. Then, the electric push rod 403 lifts the suction cup 308 again, and then the drive motor 202 is started, causing the output end of the drive motor 202 to drive the rotating rod 203 to rotate 90 degrees, so that the slide table 206, which was originally located in the middle of the U-shaped slide 201, moves along the U-shaped slide 201 to one end of the U-shaped slide 201. At this point, the adhered product can be removed and a new substrate can be placed. At the same time, the substrate, which was originally located on the slide table 206 at the other end of the U-shaped slide 201, moves to the middle of the U-shaped slide 201 for optical film adhesion.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
