It is an important medium for visual interaction between electronic devices and people. It can convert electronic signals into visible optical signals. Common types include LCD screens and OLED screens. The surface of the display screen is covered with an outer layer of glass to protect the internal polarizing layer, touch layer, etc. After the display screen is produced, 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, lamination processing needs to be carried out through cleaning, laminating and exhausting processes.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a coating device for display screen production and processing, which has the following beneficial effects: 1. By setting a rotating component, a cleaning component, a film pasting component and an exhaust component, four material placement molds are arranged on the rotating component, and the four material placement molds correspond to the vacant spaces for loading and unloading, the first station of the cleaning component, the second station of the film pasting component and the third station of the exhaust component. During processing, the rotating component rotates the rotating component of the display screen through the material placement 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 pasting component, the film pasting 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 squeezes out the air, so that cleaning, film pasting and exhausting can be carried out simultaneously, which improves the continuity of the lamination processing and greatly improves the efficiency of the lamination.

[0016] 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.

[0017] 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.

[0018] 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.

[0021] 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.

[0022] See also Figure 1-10A 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; 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.

[0023] 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; The cleaning component 6 includes a first steering wheel 602 rotatably connected to the base 1, and a cleaning assembly 604 slidably matched with the support slide 5, a first connecting rod 603 eccentrically hinged at the first steering wheel 602, the other end of which is hinged to the cleaning assembly 604, and a first synchronous pulley set 601 connected to the reduction motor 13 at the other end is transmission-connected to the first steering wheel 602; By setting the first steering wheel 602 and the first connecting rod 603, the first steering wheel 602 can utilize the connection between the first synchronous pulley group 601 and the reduction motor 13 to perform rotational motion. When performing the rotational motion, it can drive the first connecting rod 603 hinged thereto to reciprocate. When the first connecting rod 603 moves, it can drive the cleaning component 604 connected thereto to move linearly back and forth on the supporting slide 5. The cleaning component 6 utilizes the linear reciprocating motion and the fit with the display screen to achieve the purpose of cleaning the display screen.

[0024] The cleaning assembly 604 includes a first sliding frame 6041 that is slidably matched with the supporting sliding frame 5, the first sliding frame 6041 is hinged with the first connecting rod 603, a brush wheel 6044 that is in contact 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 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 are in opposite directions are provided on the material placement mold 4, and a limiting component 8 that uses friction to limit the rotation of the brush wheel 6044 is provided on the side of the first sliding frame 6041; By setting the wet brush surface 6043 and the dry brush surface 6042, when performing cleaning work, the wet brush surface 6043 on the brush wheel 6044 will first contact the display screen, and the display screen will be preliminarily cleaned with the cleaning liquid. The wet cleaning liquid can remove some solidified stains. When the brush wheel 6044 moves to the end, the gear 6045 on its end surface will engage with the reversing component 7, and the reversing component 7 will be used to rotate the brush wheel 6044 180 degrees, so that the dry brush surface 6042 faces downward and contacts the display screen. At this time, the brush wheel 6044 will be reset under the drive of the first sliding frame 6041. At this time, the dry brush surface 6042 will wipe the dirt on the display screen together with the cleaning liquid, thereby achieving a comprehensive and efficient cleaning effect.

[0025] The reversing component 7 includes a fixed plate 701 disposed on the material placing mold 4, an inclined slide 702 is disposed on the fixed plate 701, a pin 704 is slidably fitted in the inclined slide 702, a rack 703 meshing with the gear 6045 is fixedly disposed on the pin 704, and a second spring 705 connected to the fixed plate 701 is disposed under the rack 703; By setting the inclined slide 702, when the moving direction of the brush wheel 6044 is consistent with the inclination direction of the inclined slide 702, the gear 6045 will mesh with the rack 703 in the positive direction and apply a horizontal thrust to the rack 703, so that the rack 703 moves horizontally. Since the rack 703 is located at the top of the inclined slide 702 under the support of the pin shaft 704 and the second spring 705, the rack 703 cannot move further at this time, and then the thrust is reacted on the gear 6045, so that the gear 6045 rotates. When the moving direction of the brush wheel 6044 is opposite to the inclination direction of the inclined slide 702, the gear 6045 will mesh with the rack 703 in the opposite direction, and will also squeeze the rack 703. However, at this time, after being subjected to force, the rack 703 slides under the support of the pin shaft 704 under the inclined slide 702, so that it cannot mesh with the gear 6045, and thus cannot drive the gear 6045 to rotate, thereby achieving the effect of unidirectional driving of the gear 6045. It should also be further explained that the second spring 705 supports the rack 703, so that the rack 703 normally remains at the top of the inclined slide 702, which is convenient for cooperation with the gear 6045, and after the rack 703 is reversely squeezed, the rack 703 can be pushed back to its original position in time to facilitate subsequent work.

[0026] The limiting component 8 includes a fixed block 803 fixedly arranged on the side of the first sliding frame 6041, and a friction plate 801 slidably arranged on the side of the first sliding frame 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; By setting the friction plate 801 and the first spring 802, the friction plate 801 can fit 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 applied to the gear 6045 exceeds the friction force of the friction plate 801, thereby preventing the gear 6045 from being pushed by the rack 703 to rotate when it reversely meshes with the rack 703, thereby ensuring the stability of the rotation reversal of the brush wheel 6044, and the first spring 802 applies pressure to the friction plate 801, so that the friction plate 801 can fit with the brush wheel 6044, and can be automatically replenished after the friction plate 801 is worn.

[0027] The exhaust component 3 includes a second steering wheel 302 rotatably connected to the machine base 1, and an exhaust assembly 304 slidably matched with the support slide 5, a second connecting rod 303 eccentrically hinged to the second steering wheel 302, the other end of which is hinged to the exhaust assembly 304, and a second synchronous pulley set 301 connected to the reduction motor 13 at the other end is transmission-connected to the second steering wheel 302; 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.

[0028] 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.

[0029] 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; 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.

[0030] 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.

When lamination is required, the downward pressure cylinder 903 will move downward, use the suction cup 905 to absorb the protective film, and at the same time use the third spring 904 to drive the pressure plate 908 downward, so that the pressure plate 908 squeezes the protective film on the cutter 907, and uses the cutter 907 to cut out the protective film of the corresponding display screen size. Then, the downward pressure cylinder 903 uses the suction cup 905 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 908 is resisted by the cutter 907 and slides upward relative to the downward pressure cylinder 903, thereby achieving a stable cutting effect and avoiding the problem of distortion and deformation of the protective film during cutting due to its soft texture.

[0031] The rotating component 2 includes a turntable 201 disposed on the machine base 1 and connected to the reducer 16. The turntable 201 is provided with a positioning block 202 that fits the material placement mold 4. The center of the turntable 201 is provided with a vacuum tube 11. The end surface of the vacuum tube 11 is provided with a docking valve 12 connected to the material placement mold 4. By setting the positioning block 202 and the vacuum tube 11, the positioning block 202 can fit with the material placement mold 4, so that the material placement mold 4 can be quickly positioned when replaced, and the vacuum tube 11 can absorb air after the display screen is placed in the material placement mold 4, so that the display screen is adsorbed in the material placement mold 4, thereby ensuring the stability of the display screen placement and avoiding the problem of shaking of the display screen when the turntable 201 rotates.

[0032] The material placement mold 4 includes a mold plate 401 that fits with the positioning block 202. The mold plate 401 is provided with a placement groove 402 that fits with the display screen. The mold plate 401 is provided with an adsorption hole 403 that communicates with the docking valve 12 at a position corresponding to the placement groove 402. By setting the placement groove 402 and the adsorption hole 403, the placement groove 402 can be embedded with the display screen, so that the display screen can be stably placed in the placement groove 402, and the adsorption hole 403 can cooperate with the vacuum tube 11 to achieve the effect of adsorbing and fixing the display screen. In addition, by using placement grooves 402 of different sizes and depths, display screens of corresponding sizes and thicknesses can be placed to achieve a diversified coating processing effect.

[0033] The docking valve 12 comprises an inner valve body 1202 connected to the material placing component and an outer valve body 1201 connected to the vacuum tube 11. The inner valve body 1202 is inserted into the outer valve body 1201. A sealing plate 1204 is arranged in the outer valve body 1201. A fourth spring 1205 connected to the inner wall of the outer valve body 1201 is arranged on the back of the sealing plate 1204. A pin 1203 for pushing the sealing plate 1204 is arranged in the inner valve body 1202. By providing a sealing plate 1204 and a ejector pin 1203, the sealing plate 1204 is normally pushed by the fourth spring 1205 so that the sealing plate 1204 fits against the inner wall of the outer valve body 1201 and seals the outer valve body 1201 to prevent the outer valve body 1201 from opening and sucking in foreign matter. After the inner valve body 1202 is plugged into the outer valve body 1201, the ejector pin 1203 can push the sealing plate 1204 to separate the sealing plate 1204 from the inner wall of the outer valve body 1201, so that the inner valve body 1202 is connected to the inner part of the outer valve body 1201, thereby achieving the purpose of sucking air.

[0034] The positioning block 202 is rotatably provided with a rotating knob 205, a connecting plate 204 is provided on the side of the rotating knob 205, arc plates 206 are provided at both ends of the connecting plate 204, a first annular groove 203 corresponding to the rotating path of the arc plate 206 is provided on the positioning block 202, and a second annular groove 404 corresponding to the rotating path of the arc plate 206 is provided on the mold plate body 401; By setting the arc plate 206, when the mold plate body 401 needs to be taken out, the connecting plate 204 is rotated by the rotating knob 205, and the connecting plate 204 drives the arc plate 206 to rotate, so that the arc plate 206 rotates into the first annular groove 203 and separates from the second annular groove 404. At this time, the mold plate body 401 loses its fixation and can be taken out freely. When the mold plate body 401 needs to be fixed, the connecting plate 204 is continued to be rotated by the rotating knob 205, so that the connecting plate 204 drives the arc plate 206 to rotate into the second annular groove 404, and the mold plate body 401 is bitten by the arc plate 206, so as to achieve the purpose of quickly fixing the mold plate body 401.

[0035] Working principle: Place the display screen on the material placement mold 4, then drive the motor 15 to drive the rotating component 2 to rotate step by step through the reducer 16, and the rotating component 2 uses the material placement mold 4 to transport the display screen to the cleaning component 6, the coating component and the exhaust component 3 in sequence; During cleaning, the reduction motor 13 drives the first steering wheel 602 to rotate through the first synchronous pulley set 601, and the first steering wheel 602 drives the first sliding frame 6041 to move back and forth in a straight line through the first connecting rod 603, and the first sliding frame 6041 drives the brush wheel 6044 to move on the display screen to wipe the dust on the display screen; During the laminating operation, the downward pressing cylinder 903 drives the pressing plate 908 and the suction cup 905 to fit the protective film, and the pressing plate 908 squeezes the protective film against the cutter 907, so that the protective film is cut to the size corresponding to the display screen, and then the downward pressing cylinder 903 uses the suction cup 905 to continue to move downward to stick the cut protective film on the display screen; During exhaust operation, 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 frame 3041 to move back and forth in a straight line using the second connecting rod 303. The second sliding frame 3041 drives the exhaust plate 3042 to move on the protective film, presses the protective film against the display screen, and squeezes out the air.
