Description

Technical Field

[0001] The present invention relates to the technical field of display screen film laminating, and specifically relates to a film laminating device for display screen production and processing. Background Art

[0002] A display screen is an output device used to display various visual information such as images, texts, and videos. It is an important medium for visual interaction between electronic devices and people, capable of converting electronic signals into visible optical signals. Common types include LCD display screens and OLED display screens. An outer layer of glass is covered on the surface of the display screen to protect internal components such as the polarizing layer and touch layer. After the production of the display screen is completed, in order to prevent the outer layer of glass from being scratched during storage or transportation, a protective film needs to be covered on the outer layer of glass.

[0003] In the prior art, film laminating treatment needs to be carried out through cleaning, film laminating, and air exhaust processes. First, the display screen needs to be cleaned before film laminating to prevent dust from being covered inside the protective film. After film laminating, air bubbles also need to be discharged to prevent affecting the protection effect of the protective film. However, existing film laminating devices can only carry out the film laminating work of subsequent display screens after one display screen has completed the process, resulting in low processing efficiency.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the present invention provides a film laminating device for display screen production and processing, having the following beneficial effects:

[0023] 1. By providing a rotating member, a cleaning component, a film sticking component, and an exhaust component, there are four material placing molds on the rotating member. The four material placing molds respectively correspond to an idle space convenient for loading and unloading, a first station corresponding to the cleaning component, a second station corresponding to the film sticking component, and a third station corresponding to the exhaust component. During processing, the rotating member rotates the display screen through the material placing mold. When the display screen rotates to the cleaning component, the cleaning component removes the dust on the display screen. When the display screen moves to the film sticking component, the film sticking component pastes the protective film on the display screen. When the display screen moves to the exhaust component, the exhaust component presses the protective film and extrudes the air, so that the cleaning, film sticking, and exhaust operations can be carried out synchronously, improving the coherence of the film laminating process and greatly enhancing the film laminating efficiency.

[0024] 2. By setting the first steering wheel and the second steering wheel, the first steering wheel and the second steering wheel can be connected to the cleaning component and the exhaust component by using the first connecting rod and the second connecting rod, and drive them to move back and forth in a straight line, so that the cleaning component and the exhaust component can move on the display screen, so as to achieve the purpose of cleaning the display screen and squeezing out bubbles. At the same time, the first steering wheel and the second steering wheel are connected to the reduction motor by using the first synchronous pulley group and the second synchronous pulley group, so that the first steering wheel and the second steering wheel can move synchronously by using the same driving source, which saves the driving equipment and ensures that the cleaning component and the exhaust component can operate synchronously, thereby ensuring the smooth operation process.

[0025] 3. By setting the pressure plate and the cutter, the active shaft and the driven shaft will place the protective film between the cutter and the pressure plate. When lamination is required, the downward pressure cylinder will move downward, use the suction cup to absorb the protective film, and use the third spring to drive the pressure plate downward, so that the pressure plate squeezes the protective film on the cutter, and use the cutter to cut out the protective film of the corresponding display screen size. Then the downward pressure cylinder uses the suction cup to continue to drive the protective film downward to make the protective film stick to the display screen. At the same time, the pressure plate is resisted by the cutter and slides upward relative to the downward pressure cylinder to achieve a stable cutting effect, avoiding the problem of distortion and deformation during cutting due to the soft texture of the protective film.

[0026] 4. By setting up a third synchronous pulley group, one end of the third synchronous pulley group is directly connected to the driving motor, and the other end is connected to the active rotating shaft. When the driving motor drives the rotating part to rotate through the reducer, the active rotating shaft will be driven to rotate through the third synchronous pulley group at the same time. When the active rotating shaft rotates, the scraps of the protective film will be rolled up and the raw material of the protective film will be pulled, so that the protective film is actively replenished and can run synchronously with the rotating part, which saves driving equipment and improves the operation efficiency.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figures 1-10 A coating device for display screen production and processing, comprising a machine base 1, a reduction motor 13 and a driving motor 15 are arranged in the machine base 1, a reduction gear 16 is arranged on the end face of the output shaft of the driving motor 15, and a third synchronous pulley group 10 is connected to the side, the output end of the reduction gear 16 passes through the machine base 1 and is connected to a rotating component 2, four material placement molds 4 are arranged in a circular array on the rotating component 2, a cleaning component 6, a film pasting component 9 and an exhaust component 3 corresponding to different material placement molds 4 are arranged on the machine base 1, the cleaning component 6 and the exhaust component 3 are connected to the reduction motor 13 by transmission, the film pasting component 9 is connected to the third synchronous pulley group 10 by transmission, and the side of the third synchronous pulley group 10 is matched with a chain change-direction wheel frame 14 connected to the machine base 1;

[0053] By setting a third synchronous pulley group 10, one end of the third synchronous pulley group 10 is directly connected to the drive motor 15, and the other end is connected to the film-applying component 9. When the drive motor 15 drives the rotating component 2 to rotate through the reducer 16, the film-applying component 9 will be driven to work through the third synchronous pulley group 10 at the same time. When the film-applying component 9 is working, the scraps of the protective film will be rolled up and the raw materials of the protective film will be pulled, so that the protective film can be actively replenished and can be synchronized with the rotating component 2. While saving driving equipment, the operation efficiency is improved. In addition, it needs to be further explained that the rotating component 2 is indirectly connected to the drive motor 15 by the reducer 16, and the third synchronous pulley group 10 is directly connected to the drive motor 15. Therefore, when the rotating component 2 completes the stepping rotation of a workstation, the film-applying component 9 can also complete the winding of the scraps of the protective film.

[0054] The machine base 1 is provided with a support slide 5 which is slidably matched with the cleaning component 6 and the exhaust component 3;

[0055] The cleaning component 6 includes a first steering wheel 602 rotatably connected to the machine base 1 and a cleaning assembly 604 slidably engaged with the support carriage 5. A first connecting rod 603 is eccentrically hinged to the first steering wheel 602, and the other end of the first connecting rod 603 is hinged to the cleaning assembly 604. A first synchronous pulley set 601 is drivingly connected to the lower part of the first steering wheel 602, and the other end of the first synchronous pulley set 601 is connected to the reduction motor 13.

[0056] By providing the first steering wheel 602 and the first connecting rod 603, the first steering wheel 602 can perform a rotational motion by using the connection between the first synchronous pulley set 601 and the reduction motor 13. When the first steering wheel 602 performs a rotational motion itself, it can drive the first connecting rod 603 hinged thereto to reciprocate. When the first connecting rod 603 moves, it can drive the cleaning assembly 604 connected thereto to linearly reciprocate on the support carriage 5. The cleaning component 6 uses the linear reciprocating motion and the fitting with the display screen to achieve the purpose of cleaning the display screen.

[0057] The cleaning assembly 604 includes a first sliding frame 6041 slidably engaged with the support carriage 5. The first sliding frame 6041 is hinged to the first connecting rod 603. A brush wheel 6044 that fits with the material placement mold 4 is provided under the first sliding frame 6041. A wet brush surface 6043 and a dry brush surface 6042 are provided on the side surface of the brush wheel 6044. A gear 6045 is provided on the end surface of the brush wheel 6044. Two reversing components 7 that mesh with the gear 6045 and have opposite directions are provided on the material placement mold 4. A limiting component 8 that restricts the rotation of the brush wheel 6044 by using friction is provided on the side surface of the first sliding frame 6041.

[0058] By providing the wet brush surface 6043 and the dry brush surface 6042, during the cleaning operation, the wet brush surface 6043 on the brush wheel 6044 first contacts the display screen, and the cleaning liquid is used to initially clean the display screen. The moist cleaning liquid can remove some solidified stains. When the brush wheel 6044 moves to the end, the gear 6045 on its end surface will mesh with the reversing component 7, and the reversing component 7 will rotate the brush wheel 6044 by 180 degrees, so that the dry brush surface 6042 faces downward and contacts the display screen. At this time, the brush wheel 6044 will reset under the drive of the first sliding frame 6041. At this time, the dry brush surface 6042 will wipe the dirt and the cleaning liquid on the display screen, achieving the effect of comprehensive and efficient cleaning.

[0059] The reversing component 7 includes a fixing plate 701 provided on the material placement mold 4. An inclined sliding frame 702 is provided on the fixing plate 701. A pin shaft 704 is slidably engaged in the inclined sliding frame 702. A rack 703 that meshes with the gear 6045 is fixedly provided on the pin shaft 704. A second spring 705 that is connected to the fixing plate 701 is provided under the rack 703.

[0060] By setting the inclined carriage 702, when the moving direction of the brush wheel 6044 is the same as the inclination direction of the inclined carriage 702, the gear 6045 will be in positive engagement with the rack 703 and apply a horizontal thrust to the rack 703, causing the rack 703 to move horizontally. Since the rack 703 is supported by the pin shaft 704 and the second spring 705 at the top of the inclined carriage 702, the rack 703 cannot continue to move at this time, and thus the thrust is reacted on the gear 6045, causing the gear 6045 to rotate. When the moving direction of the brush wheel 6044 is opposite to the inclination direction of the inclined carriage 702, the gear 6045 will be in reverse engagement with the rack 703 and will also squeeze the rack 703. However, when the rack 703 is stressed at this time, it slides down the inclined carriage 702 under the support of the pin shaft 704, making it unable to engage with the gear 6045, and thus unable to drive the gear 6045 to rotate, achieving the effect of unidirectional driving of the gear 6045;

[0061] In addition, it should be further explained that the second spring 705 supports the rack 703, enabling the rack 703 to be maintained at the top of the inclined carriage 702 under normal conditions, facilitating the cooperation with the gear 6045, and can promptly push the rack 703 to reset after the rack 703 is reversely squeezed, facilitating subsequent work.

[0062] The limiting component 8 includes a fixed block 803 fixedly arranged on the side surface of the first sliding carriage 6041 and a friction plate 801 slidably arranged on the side surface of the first sliding carriage 6041. The friction plate 801 is in contact with the brush wheel 6044, and a first spring 802 is arranged between the friction plate 801 and the fixed block 803;

[0063] By setting the friction plate 801 and the first spring 802, the friction plate 801 can be in contact with the brush wheel 6044 and limit the rotation of the brush wheel 6044, so that the gear 6045 can rotate only when the force on the gear 6045 exceeds the frictional force of the friction plate 801, preventing the gear 6045 from being pushed to rotate by the rack 703 when the gear 6045 is in reverse engagement with the rack 703, ensuring the stability of the rotation direction change of the brush wheel 6044. The first spring 802 applies pressure to the friction plate 801, enabling the friction plate 801 to be in contact with the brush wheel 6044 and can automatically make up for wear after the friction plate 801 is worn.

[0064] The exhaust component 3 includes a second steering wheel 302 rotatably connected to the machine base 1 and an exhaust assembly 304 slidably engaged with the support carriage 5. An eccentric hinge is arranged on the second steering wheel 302, and the other end is hinged to the exhaust assembly 304 by a second connecting rod 303. A second synchronous pulley set 301 is connected to the lower part of the second steering wheel 302, and the other end is connected to the reduction motor 13;

[0065] By setting up the second steering wheel 302 and the second connecting rod 303, the second steering wheel 302 can utilize the connection between the second synchronous pulley set 301 and the reduction motor 13 to perform rotational motion. When performing the rotational motion, it can drive the second connecting rod 303 hinged thereto to reciprocate. When the second connecting rod 303 moves, it can drive the exhaust component 304 connected thereto to move linearly back and forth on the supporting slide 5. The exhaust component 3 utilizes the linear reciprocating motion and the fit with the display screen to press the protective film against the display screen and squeeze out the bubbles.

[0066] It should also be further explained that the first synchronous pulley group 601, the second synchronous pulley group 301 and the third synchronous pulley group 10 all use toothed belts and corresponding pulleys for connection and transmission. The meshing between the teeth can prevent the problem of elastic sliding, and have the advantages of low manufacturing cost, low maintenance cost, stable operation, and low working noise.

[0067] The exhaust assembly 304 includes a second sliding frame 3041 that is slidably matched with the supporting sliding frame 5, the second sliding frame 3041 is hinged with the second connecting rod 303, a hinge shaft 3043 is rotatably connected inside the second sliding frame 3041, an exhaust plate 3042 that fits the material placement mold 4 is provided between the hinge shafts 3043, and a coil spring 3044 connected to the second sliding frame 3041 is provided on the side of the hinge shaft 3043;

[0068] By setting the exhaust plate 3042 and the coil spring 3044, the exhaust plate 3042 is rotatably connected to the second sliding frame 3041 by the hinge shaft 3043, and can rotate itself, and the coil spring 3044 is used to apply downward pressure, so that the exhaust plate 3042 can fit tightly on the protective film, thereby achieving the purpose of pressing the protective film and squeezing out bubbles.

[0069] The film sticking component 9 includes a rotating shaft support frame 901 and a cylinder support frame 902 arranged on the machine base 1. The rotating shaft support frame 901 is provided with a driven rotating shaft 906 for placing the film roll raw material and a driving rotating shaft 909 for placing the film roll edge material. The driving rotating shaft 909 is connected to the third synchronous pulley group 10 in a transmission manner.

[0070] A downward pressing cylinder 903 is provided on the cylinder support frame 902, a suction cup 905 is provided under the output shaft of the downward pressing cylinder 903, a pressing plate 908 is provided on the side for sliding, a third spring 904 connected to the downward pressing cylinder 903 is provided on the pressing plate 908, a cutter 907 is provided under the rotating shaft support frame 901, the size of the cutter 907 is consistent with the size of the display screen, and the position corresponds to the pressing plate 908;

[0071] By setting the pressing plate 908 and the cutting knife 907, the driving rotating shaft 909 and the driven rotating shaft 906 will place the protective film between the cutting knife 907 and the pressing plate 908. When film laminating is required, the pressing cylinder 903 will move downward, adsorb the protective film by using the suction cup 905, and at the same time drive the pressing plate 908 downward by using the third spring 904, so that the pressing plate 908 presses the protective film against the cutting knife 907, and the cutting knife 907 is used to cut out the protective film corresponding to the size of the display screen. Subsequently, the pressing cylinder 903 continues to drive the protective film downward by using the suction cup 905, so that the protective film is pasted on the display screen. At the same time, the pressing plate 908 is resisted by the cutting knife 907 and slides upward relative to the pressing cylinder 903, achieving the effect of stable cutting and avoiding the problem of distortion and deformation of the protective film during cutting due to its soft texture.

[0072] The rotating component 2 includes a turntable 201 provided on the machine base 1 and connected to the speed reducer 16. The turntable 201 is provided with a positioning block 202 that fits with the material placing mold 4. A vacuum pumping tube 11 is provided at the center of the turntable 201, and a docking valve 12 connected to the material placing mold 4 is provided at the end face of the vacuum pumping tube 11.

[0073] By setting the positioning block 202 and the vacuum pumping tube 11, the positioning block 202 can fit with the material placing mold 4, enabling the material placing mold 4 to be quickly positioned when replaced. The vacuum pumping tube 11 can, after the display screen is placed in the material placing mold 4, adsorb the display screen in the material placing mold 4 by sucking air, ensuring the stable placement of the display screen and avoiding the problem of the display screen shaking when the turntable 201 rotates.

[0074] The material placing mold 4 includes a mold plate body 401 that fits with the positioning block 202. An installation groove 402 that fits with the display screen is formed on the mold plate body 401, and an adsorption hole 403 communicated with the docking valve 12 is formed in the mold plate body 401 at a position corresponding to the installation groove 402.

[0075] By setting the installation groove 402 and the adsorption hole 403, the installation groove 402 can fit with the display screen, enabling the display screen to be stably placed in the installation groove 402. The adsorption hole 403 can cooperate with the vacuum pumping tube 11 to achieve the effect of adsorbing and fixing the display screen. Additionally, by using installation grooves 402 with different sizes and depths, display screens of corresponding sizes and thicknesses can be placed, achieving the effect of diversified film laminating processing.

[0076] The docking valve 12 includes an inner valve body 1202 connected to the material placing component and an outer valve body 1201 connected to the vacuum pumping tube 11. The inner valve body 1202 is inserted into the outer valve body 1201. A sealing plate 1204 is provided in the outer valve body 1201. A fourth spring 1205 connecting the back of the sealing plate 1204 to the inner wall of the outer valve body 1201 is provided, and a thimble 1203 for pushing the sealing plate 1204 is provided in the inner valve body 1202.

[0077] By providing a sealing plate 1204 and a thimble 1203, the sealing plate 1204 is pushed by a fourth spring 1205 under normal conditions, causing it to fit against the inner wall of the outer valve body 1201 and seal the outer valve body 1201, preventing the problem of foreign objects being inhaled due to the opening of the outer valve body 1201. The thimble 1203 can, after the inner valve body 1202 is inserted into the outer valve body 1201, push the sealing plate 1204, causing the sealing plate 1204 to separate from the inner wall of the outer valve body 1201, enabling the inner valve body 1202 to communicate with the inside of the outer valve body 1201 and achieving the purpose of sucking air.

[0078] A rotary knob 205 is rotatably provided on the positioning block 202. A connecting plate 204 is provided on the side of the rotary knob 205. Arc-shaped plates 206 are provided at both ends of the connecting plate 204. A first annular groove 203 corresponding to the rotation path of the arc-shaped plate 206 is provided on the positioning block 202. A second annular groove 404 for the rotation path of the arc-shaped plate 206 is formed on the die plate body 401.

[0079] By providing the arc-shaped plate 206, when the die plate body 401 needs to be removed, the connecting plate 204 is rotated by the rotary knob 205. The connecting plate 204 drives the arc-shaped plate 206 to rotate, causing the arc-shaped plate 206 to rotate into the first annular groove 203 and separate from the second annular groove 404. At this time, the die plate body 401 loses its fixation and can be freely removed. When the die plate body 401 needs to be fixed, the connecting plate 204 is continuously rotated by the rotary knob 205, causing the connecting plate 204 to drive the arc-shaped plate 206 to rotate into the second annular groove 404, and using the arc-shaped plate 206 to bite the die plate body 401 to achieve the purpose of quickly fixing the die plate body 401.

[0080] Working principle: Place the display screen on the feeding die 4. Subsequently, the driving motor 15 drives the rotating member 2 to rotate step by step through the speed reducer 16. The rotating member 2 uses the feeding die 4 to sequentially convey the display screen under the cleaning member 6, the film laminating member, and the exhaust member 3;

[0081] When performing the cleaning work, the reduction motor 13 drives the first steering wheel 602 to rotate through the first synchronous pulley set 601. The first steering wheel 602 drives the first sliding frame 6041 to perform a linear reciprocating movement using the first connecting rod 603. The first sliding frame 6041 drives the brush wheel 6044 to move on the display screen to wipe the dust on the display screen;

[0082] When performing the film laminating work, the downward pressing air cylinder 903 drives the pressing plate 908 and the suction cup 905 to fit against the protective film. The pressing plate 908 presses the protective film against the cutting knife 907, causing the protective film to be cut to the size corresponding to the display screen. Subsequently, the downward pressing air cylinder 903 continues to move downward using the suction cup 905 to paste the cut protective film on the display screen;

[0083] When performing the exhaust work, the reduction motor 13 drives the second steering wheel 302 to rotate through the second synchronous pulley set 301. The second steering wheel 302 drives the second sliding carriage 3041 to perform a linear reciprocating movement by means of the second connecting rod 303. The second sliding carriage 3041 drives the exhaust plate 3042 to move on the protective film, pressing the protective film tightly against the display screen and squeezing out the air.

[0084] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
