Description

Technical Field

[0001] This invention patent relates to the technical field of polarizer lamination. Specifically, it relates to a large-size TP transfer device. Background Art

[0002] With the development of the network and technology towards a more broadband direction, the mobile communication industry will move towards a true mobile information era; mobile terminals such as mobile phones, laptops, and tablet computers have powerful processing capabilities and are evolving from simple communication tools into comprehensive information processing platforms.

[0003] As an important part of the mobile terminal, the display screen has functions such as display and touch control. The display screen includes a screen cover plate and a liquid crystal module, and the liquid crystal module is laminated on the screen cover plate. Of course, the screen cover plate can be made of glass or other materials, depending on the requirements of the display screen.

[0004] Currently, with the market demand and technological development, generally a film material is attached to the outside of the display screen. On the one hand, it protects the display screen, and on the other hand, it can also make the imaging effect of the display screen better.

[0005] However, in the prior art, when transferring the display screen, generally the display screen is transported to the lamination station through a handling structure. After lamination and discharging, the transportation is repeated. Obviously, this method has low transportation efficiency and reduces the production efficiency at the same time. Summary of the Invention

[0006] The purpose of the present invention is to provide a large-size TP transfer device, aiming to solve the problem of low transportation efficiency when transferring the display screen in the prior art.

[0007] The present invention is implemented as follows. A large-size TP transfer device includes:

[0008] A screen board loading mechanism for placing the screen board;

[0009] A screen board transfer mechanism for temporarily placing the screen board;

[0010] A screen board handling mechanism for transporting the screen board from the screen board loading mechanism to the screen board transfer mechanism;

[0011] An upper lamination platform for adsorbing the screen board placed by the transfer mechanism and moving the screen board to the lamination station to laminate the screen board with the polarizer; both the screen board handling mechanism and the upper lamination platform are arranged between two cross rails and move along the length direction of the cross rails.

[0012] Optionally, it further includes a screen panel film tearing mechanism, which is arranged between the screen panel loading mechanism and the screen panel transfer mechanism. When the screen panel handling mechanism moves to the screen panel film tearing mechanism, the screen panel film tearing mechanism is used to tear off the protective film of the screen panel.

[0013] Optionally, along the transfer direction of the screen panel, a waste film cavity is arranged on one side of the screen panel film tearing mechanism, and the screen panel film tearing mechanism is fixed on one side of the waste film cavity.

[0014] Optionally, an electrostatic eliminator is also arranged between the screen panel film tearing mechanism and the screen panel transfer mechanism.

[0015] Optionally, it further includes a blanking correction mechanism, and the upper laminating platform moves the laminated screen panel to the blanking correction mechanism.

[0016] Optionally, the screen panel loading mechanism includes a roller conveying mechanism, a transfer lifting mechanism, a screen panel alignment mechanism, and a screen panel stop mechanism. Among them, the roller conveying mechanism is used to place and convey the screen panel; the transfer lifting mechanism is used to adsorb and lift the screen panel; the screen panel alignment mechanism is used to correct the position of the screen panel to make it centered; the screen panel stop mechanism is used to limit the continuous movement of the screen panel.

[0017] Optionally, an electrostatic ion air bar is arranged at the end of the roller conveying mechanism.

[0018] Optionally, the transfer lifting mechanism includes a liftable transfer lifting frame, and a plurality of vacuum suction cups are arranged on the transfer lifting frame.

[0019] Optionally, the screen panel handling mechanism includes a screen panel handling frame, a plurality of vacuum suction nozzles, a screen panel handling fixture plate, and a first vacuum gas storage tank.

[0020] Optionally, the upper laminating platform includes an upper laminating frame, an upper laminating fixture plate, and a second vacuum gas storage tank. The upper laminating fixture plate is arranged at the lower part of the upper laminating frame, and both ends of the upper laminating frame are mounted on the two cross rails and move; the upper laminating fixture plate has a plurality of suction holes, and the second vacuum gas storage tank is connected to the plurality of suction holes of the upper laminating fixture plate through pipelines.

[0021] Compared with the prior art, the large-size TP transfer device provided by the present invention includes a screen panel handling mechanism that transports the screen panel on the screen panel loading mechanism to the screen panel transfer platform, and moves the screen panel to the lamination station through the upper lamination platform. In the large-size TP transfer device provided by the present invention, compared with using a single handling mechanism, the screen panel handling mechanism and the upper lamination platform can work simultaneously, with high handling efficiency and improved production efficiency. In addition, since the screen panel handling mechanism and the upper lamination platform move between the same two cross rails, there is no need to change the orientation of the screen panel, and the production efficiency is high. It solves the problem of low handling efficiency when transferring display screens in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0043] The implementation of the present invention will be described in detail below with reference to specific embodiments.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0045] Referring to Figures 1 to 20 shown, it is a preferred embodiment provided by the present invention.

[0046] In an embodiment of the present invention, the large-size polarizing laminating machine includes a polarizer magazine 10, a laminating mechanism 40, a polarizer film tearing mechanism 50, a polarizer handling mechanism, a panel loading mechanism 60, a panel transfer mechanism 70, a panel handling mechanism 81, and an upper laminating platform 82. Among them, the large-size TP transfer device includes a panel loading mechanism 60, a panel transfer mechanism 70, a panel handling mechanism 81, and an upper laminating platform 82.

[0047] The polarizer magazine 10 is used to place polarizers.

[0048] The polarizer magazine 10 includes a magazine body 11 and a material chuck 12. The magazine body 11 is provided with chuck support transmission wheels 111. The material chuck 12 is placed on the material chuck 12 support transmission wheels 111 to facilitate quickly moving the material chuck 12 onto the magazine body 11. The chuck support transmission wheels 111 include multiple groups, each group having multiple wheels. Each group of chuck support transmission wheels 111 is connected by the same transmission rod to ensure stable support of the material chuck 12. Moreover, each group of support transmission wheels at the edge has a retaining wheel to prevent the material chuck 12 from moving along the length direction of the transmission rod. In addition, along the length direction of the transmission rod, material chuck 12 clamping cylinders are respectively provided on both sides of the magazine body 11 to further prevent the movement of the material chuck 12. Additionally, on the side of the magazine body 11 away from the feeding position, there are two spaced-apart chuck limit parallel adjustment blocks, enabling the material chuck 12 to abut against the two chuck limit parallel adjustment blocks, thereby ensuring parallelism and facilitating subsequent feeding alignment. And, multiple horizontal adjustment fixing blocks are provided on the peripheral side edges of the magazine body 11. By adjusting the fixing angles of the horizontal adjustment fixing blocks, the material chuck 12 on the magazine body 11 is horizontally arranged to facilitate material taking.

[0049] Secondly, an electrostatic elimination ion bar 114 is also provided on the side of the magazine body 11 to eliminate the static electricity of the polarizer, facilitating the separation of adhered polarizers. A stack detection mechanism 112 and a stack blowing-off mechanism 113 are also provided on the side of the magazine body 11. Whether the polarizers are adhered is determined by detecting the light transmittance of the polarizers. The adhered polarizers are peeled off by the stack blowing-off mechanism 113 for subsequent lamination with the panel.

[0050] Furthermore, the material chuck 12 is provided with multiple material fixing stop blocks 121 and multiple material adjustment stop blocks 122. The material fixing stop blocks 121 are provided on two adjacent sides, and the material adjustment stop blocks 122 are provided on two adjacent sides. The material fixing stop blocks 121 and the material adjustment stop blocks 122 are arranged opposite to each other. The material adjustment stop blocks 122 can move towards or away from the material fixing stop blocks 121. The polarizers are stacked between the material fixing stop blocks 121 and the material adjustment stop blocks 122 to prevent the polarizers from moving. By moving the material adjustment stop blocks 122, polarizers of different sizes can also be placed, facilitating use.

[0051] In this embodiment, there are multiple polarizer bins 10, specifically three. The multiple polarizer bins 10 are arranged in sequence along the moving direction of the polarizer handling mechanism, so as to facilitate the feeding of the material chucks 12 to the unused polarizer bins 10. Additionally, at the extension of the multiple polarizer bins 10, there is a storage bin 101 for polarizers. The storage bin 101 for polarizers has the same structure as the polarizer bin 10, which will not be elaborated here. An initial inspection CCD is provided between the storage bin 101 for polarizers and the polarizer bin 10. When the polarizer handling mechanism transports the polarizer to the initial inspection CCD, the initial inspection CCD is used to detect the identification of the polarizer. When the initial inspection CCD detects that the polarizer is in the reverse side, the polarizer handling mechanism moves the polarizer into the storage bin 101 for polarizers and picks up a new one. In this way, it can be avoided that the polarizer on the reverse side is moved to the subsequent workstations, resulting in inoperability at the subsequent workstations.

[0052] Moreover, in an embodiment of the present invention, a loading cart 100 for the material chuck 12 is provided. The loading cart 100 has multiple rollers arranged at intervals, and the rotation directions of the multiple rollers are the same as the rotation direction of the chuck support conveyor wheel 111, so as to facilitate directly pushing the material chuck 12 on the loading cart 100 onto the bin body 11, facilitating the loading.

[0053] In an embodiment of the present invention, the large-size polarizer laminating machine further includes a cleaning and polarizer correction mechanism 32. The cleaning and polarizer correction mechanism 32 is arranged between the polarizer bin 10 and the lower laminating platform 41. The polarizer handling mechanism transports the polarizer in the polarizer bin 10 to the cleaning and polarizer correction mechanism 32, and the cleaning and polarizer correction mechanism 32 is used to clean and correct the polarizer. The polarizer handling mechanism transports the polarizer on the cleaning and polarizer correction mechanism 32 to the lower laminating platform 41.

[0054] The cleaning and correction structure 30 includes a cleaning mechanism 31 and a polarizer correction mechanism 32. The cleaning mechanism 31 is used to clean the polarizer, and the polarizer correction mechanism 32 is used to correct the position of the polarizer.

[0055] The cleaning mechanism 31 includes a material input roller group 312, a material output roller group 314, a cleaning roller group 313, and a sheet supporting plate 311. The sheet supporting plate 311, the material input roller group 312, the cleaning roller group 313, and the material output roller group 314 are arranged in sequence. The material input roller group 312 and the material output roller group 314 are driven to rotate synchronously by a transmission gear group and a servo motor. The material input roller group 312 and the material output roller group 314 are used to traction the polarizer. In use, the polarizer handling mechanism transports one end of the polarizer to the sheet supporting plate 311, and the end is inserted into the material input roller group 312. The material input roller group 312 traction the polarizer to the cleaning roller group 313 for cleaning, and then traction it to the material output roller group 314 to synchronously traction the polarizer. The above cleaning roller group 313 includes a plurality of sticky cleaning rollers. The polarizer passes through the plurality of cleaning rollers, thereby adhering dust and other impurities on the polarizer to achieve cleaning. In addition, rotatable sticky dust paper roll rollers are respectively arranged on the upper and lower sides of the two cleaning roller groups 313. A sticky dust paper roll is pasted on the sticky dust paper roll roller, and the sticky dust paper roll roller is closely attached to the cleaning roller to stick the dust on the cleaning roller to ensure the continuous use of the cleaning roller. Lifting cylinders are provided on both sides below the lower sticky dust paper roll roller to make the lower sticky dust paper roll roller closely attached to the cleaning roller, and the upper sticky dust paper roll roller is closely attached to the cleaning roller by its own gravity. And a storage box storing the sticky dust paper roll is provided below the cleaning mechanism 31. The storage box can be pulled out of the cleaning mechanism 31 to facilitate the replacement of the sticky dust paper roll. The above material input roller group 312 includes a material input drive roller and a material input clamping roller. The material input drive roller is driven to rotate by a transmission gear group and a servo motor. The material input clamping roller is driven to move up and down by a lifting cylinder. When the end of the polarizer is placed on the material input drive roller, the material input clamping roller moves downward to clamp the polarizer to ensure the traction force of the material input roller group 312. The structure of the material output roller group 314 is the same as that of the material input roller group 312 and will not be described in detail.

[0056] The polarizer correction mechanism 32 includes a correction platform 321 and a position detection CCD 33. The correction platform 321 is provided with a plurality of correction clamping members 322 driven by the clamping cylinders. The plurality of correction clamping members 322 move towards or away from the cleaning mechanism 31 through a servo motor. When the end of the polarizer moves to the position of the correction clamping member 322, the correction clamping member 322 clamps the end of the polarizer. The above-mentioned material input roller group 312 and material output roller group 314 stop traction rotation. The correction clamping member 322 moves and moves the polarizer to the correction platform 321. At the bottom of the correction platform 321, there are a servo motor and a horizontal support adjustment mechanism for rotating the correction platform 321. The horizontal support adjustment mechanism includes a plurality of horizontal adjustment support blocks. The top of the horizontal adjustment support block has balls, which facilitates the rotation of the correction platform 321 while stably supporting the correction platform 321. The position detection CCD 33 is arranged on the side of the correction platform 321 and moves towards or away from the cleaning mechanism 31 through a servo motor drive. When the position detection CCD 33 detects that the position of the polarizer is inclined, such as when the front edge position is detected but the rear edge position is not detected, the servo motor of the correction platform 321 rotates the correction platform 321 until the position detection CCD 33 detects the positions of two points before and after, so as to straighten the polarizer and achieve calibration, which is convenient for subsequent bonding alignment.

[0057] In an embodiment of the present invention, the polarizer handling mechanism is used to handle the polarizer in the polarizer magazine 10 to the lower bonding platform 41. Specifically, in this embodiment, the polarizer handling mechanism includes a first polarizer suction mechanism 21 and a second polarizer suction mechanism 22. The first polarizer suction mechanism 21 is used to handle the polarizer in the polarizer magazine 10 to the cleaning and correction mechanism, and the second polarizer suction mechanism 22 is used to handle the polarizer on the cleaning and correction mechanism to the lower bonding platform 41.

[0058] The first polarizer suction mechanism 21 includes a suction frame 211. A suction transmission block is arranged on the upper part of the suction frame 211. The suction transmission block drives the up and down movement of the suction frame 211 through a servo motor and a linear drive module. The suction transmission block is driven to move through a linear motor module and moves along a cross beam extending in the direction from the polarizer magazine 10 to the cleaning and correction mechanism. In this way, the lifting and transmission movement of the first polarizer suction mechanism 21 are realized.

[0059] In addition, a plurality of suction nozzles 212 are provided at the lower part of the suction frame 211. The plurality of suction nozzles 212 are arranged in an array. The polarizer can be sucked through the plurality of suction nozzles 212, so as to drive the movement. In this embodiment, each suction nozzle 212 is connected to the output shaft of the sheet-taking and vibrating cylinder 213 of the suction frame 211. The polarizer is swung by the sheet-taking and vibrating cylinder 213. In this way, when the stack detection mechanism 112 of the polarizer magazine 10 detects that a plurality of polarizers are adhered, the adhered polarizers can be further separated by the vibrating cylinder 213.

[0060] In this embodiment, the second polarizer suction mechanism is located in the moving direction of the first polarizer suction mechanism, and the second polarizer suction mechanism has a similar structure to the first polarizer suction mechanism, which will not be elaborated herein.

[0061] The laminating mechanism 40 is provided with a movable lower laminating platform 41. The laminating mechanism 40 has a loading station 401, a film tearing station 402 and a laminating station 403. The lower laminating platform 41 moves along the loading station 401, the film tearing station 402 and the laminating station 403. The lower laminating platform 41 is used for adsorbing the polarizer.

[0062] In this embodiment, the laminating mechanism 40 has a rack and a guide rail extending along the loading station 401, the film tearing station 402 and the laminating station 403. The bottom of the lower laminating platform 41 has a gear driven by a servo motor. The gear meshes with the rack. The translation of the lower laminating platform 41 is realized by the forward and reverse rotation of the gear. When the lower laminating platform 41 moves to the loading station 401, the polarizer handling mechanism transports and places the polarizer on the lower laminating platform 41. The lower laminating platform 41 vacuum-adsorbs the polarizer through the through holes on the platform surface to ensure the fixed position of the polarizer. Then, the lower laminating platform 41 moves to the film tearing station 402.

[0063] The polarizer film tearing mechanism 50 is arranged above the film tearing station 402. The polarizer film tearing mechanism 50 is used for tearing off the protective film of the polarizer.

[0064] The polarizer film tearing mechanism 50 includes a film tearing plate 51 and two film tearing members. The two film tearing members are located on both sides of the film tearing plate 51. The polarizer film tearing mechanism 50 moves on the crossbeam along the direction perpendicular to the connection direction of the two film tearing members. The film tearing member has a film tearing clamping member 52 and a film tearing suction member 53. The film tearing suction member 53 is driven by a lifting cylinder provided on the film tearing member to move up and down. The film tearing clamping member 52 is a clamping cylinder. A sticker is provided on the surface of the film tearing suction member 53. When tearing the film, the film tearing suction members 53 on both sides move downward to adsorb the protective film of the polarizer on the lower fitting platform 41, causing the corners of the protective film of the polarizer to warp. Then, it drives the corners of the protective film to move upward. The film tearing clamping member 52 clamps the corners of the protective film. Then, the polarizer film tearing mechanism 50 moves through the linear motor in the crossbeam until the protective film of the polarizer is completely torn off, realizing film tearing.

[0065] In this embodiment, the above two film tearing members can move towards or away from each other on the film tearing plate 51 through a linear motor, and the film tearing clamping member 52 can move towards or away from the film tearing plate 51 through a film tearing cylinder. In this way, through the above moving structure, on the one hand, polarizers of different sizes can be torn, and on the other hand, while tearing the film, the film tearing clamping member 52 moves, which can make the film tearing more complete.

[0066] In an embodiment of the present invention, the large-size polarizer laminating machine further includes a waste film placement machine. The polarizer film tearing mechanism 50 moves back and forth along the film tearing station 402 to the waste film placement machine. The polarizer film tearing mechanism 50 moves the protective film torn from the polarizer into the waste film placement machine.

[0067] That is, when the above polarizer film tearing mechanism 50 moves along the crossbeam, it moves between the waste film placement machine and the film tearing station 402. In this way, after the film tearing is completed, the torn protective film of the polarizer can be thrown into the waste film placement machine for the next film tearing. In this embodiment, the waste film placement machine is located on one side of the film tearing station 402 along the moving direction of the polarizer film tearing mechanism 50 during film tearing. In this way, after the polarizer film tearing mechanism 50 finishes tearing the film, the protective film can be immediately thrown into the waste film placement machine, reducing the travel distance.

[0068] The panel loading mechanism 60 is used to place the panel.

[0069] The panel loading mechanism 60 includes a roller conveying mechanism 61, a transfer lifting mechanism 62, a panel alignment mechanism 63, and a panel stop mechanism 64. Among them, the roller conveying mechanism 61 is used to place and convey the panel; the transfer lifting mechanism 62 is used to adsorb the panel and lift the panel for easy handling; the panel alignment mechanism 63 is used to correct the position of the panel to make the panel centered for subsequent lamination with the polarizer; the panel stop mechanism 64 is used to limit the continuous movement of the panel and limit the movement of the panel.

[0070] Specifically, the roller conveying mechanism 61 includes a plurality of screen plate conveying roller groups 611 arranged at intervals. These plurality of screen plate conveying roller groups 611 driven by a servo motor, a gear set and a transmission rod rotate synchronously. When the screen plate is placed on the roller conveying mechanism 61, the screen plate moves along with the rotation of the screen plate conveying roller groups 611. And, at the end of the roller conveying mechanism 61, there is an electrostatic ion air bar 612 to eliminate the static electricity of the screen plate entering the roller conveying mechanism 61, which is convenient for subsequently tearing off the protective film of the screen plate or attaching the screen plate to the polarizer. In this way, during feeding, the screen plate can also be pushed onto the roller conveying mechanism 61 by the feeding cart 100, which is convenient for feeding.

[0071] The screen plate alignment mechanism 63 is located below the roller conveying mechanism 61. The screen plate alignment mechanism 63 includes two screen plate alignment plates that can move towards or away from each other. The two screen plate alignment plates move towards or away from each other synchronously through a synchronous belt and a synchronous pulley. Specifically, in one embodiment, the two screen plate alignment plates are respectively fixed on both sides of the circumferentially arranged synchronous belt. The synchronous belt is fixed by the synchronous pulley, and the synchronous pulley is driven to rotate by a servo motor. In addition, each screen plate alignment plate has a screen plate alignment frame 631. The screen plate alignment frame 631 is used to hold the screen plate to achieve the centering of the screen plate. And, on each screen plate alignment plate, there is also a positioning cylinder. The output shaft of the positioning cylinder is connected to the screen plate alignment frame 631. In this way, according to needs, the centering position of the screen plate can be adjusted, which is convenient for handling and fitting. In addition, the upper end of the screen plate alignment frame 631 has a plurality of buffer spring blocks 632, and the buffer spring blocks 632 are used to hold the screen plate as a buffer to avoid damage to the screen plate.

[0072] The screen plate stop mechanism 64 is located in front of the roller group of the roller conveying mechanism 61. The screen plate stop mechanism 64 includes a screen plate stop frame 641 and an induction optical fiber 642. The screen plate stop frame 641 is driven to move up and down by a lifting cylinder. When the induction optical fiber 642 senses the screen plate, the screen plate stop frame 641 rises to block the continuous movement of the screen plate. And, the lifting cylinder below the screen plate stop frame 641 also moves towards or away from the roller group through a positioning cylinder. In this way, the screen plate stop plate moves towards or away from the roller group through the positioning cylinder, so that the position of the screen plate is aligned with the screen plate handling mechanism 81, which is convenient for the subsequent handling of the screen plate.

[0073] The transfer lifting mechanism 62 is arranged below the roller conveyor mechanism 61. The transfer lifting mechanism 62 includes a liftable transfer lifting frame 621. The transfer lifting frame 621 is driven to lift through a servo motor and a driving lead screw at the bottom. And there are a plurality of vacuum suction cups 622 on the transfer lifting frame 621. In this embodiment, these plurality of vacuum suction cups 622 are located in the gaps between the above-mentioned roller groups. Initially, these plurality of vacuum suction cups 622 are located below the roller groups. After the above-mentioned calibration and alignment are completed, material handling is carried out. The transfer lifting frame 621 rises, and the vacuum suction cups 622 pass through the roller groups, suck and lift the screen panel to facilitate material handling.

[0074] In an embodiment of the present invention, the large-size polarizer laminating machine further includes a screen panel film tearing mechanism 501. The screen panel film tearing mechanism 501 is arranged between the screen panel loading mechanism 60 and the screen panel transfer mechanism 70. When the screen panel handling mechanism 81 moves to the screen panel film tearing mechanism 501, the screen panel film tearing mechanism 501 is used to tear off the protective film of the screen panel. In this embodiment, the screen panel film tearing mechanism 501 only operates on the screen panel that needs to have its protective film torn off, and the screen panel that does not require film tearing does not need to go through this process.

[0075] The structure of the screen panel film tearing mechanism 501 is similar to that of the polarizer film tearing mechanism 50 and will not be elaborated here. The difference is that the polarizer film tearing mechanism 50 tears the film downward, while the screen panel film tearing mechanism 501 tears the film upward. In addition, along the transfer direction of the screen panel, a waste film cavity is provided on one side of the screen panel film tearing mechanism 501. The screen panel film tearing mechanism 501 is fixed to one side of the waste film cavity. When the screen panel handling mechanism 81 handles the screen panel, the screen panel film tearing mechanism 501 clamps the corners of the protective film of the screen panel and tears the film as the screen panel handling mechanism 81 moves. After the film tearing is completed, the torn protective film is thrown into the waste film cavity.

[0076] In addition, an electrostatic eliminator is also provided between the screen panel film tearing mechanism 501 and the screen panel transfer mechanism 70. When the screen panel handling mechanism 81 safely moves the screen panel, the screen panel passes through the electrostatic eliminator to further eliminate static electricity, facilitating subsequent lamination with the polarizer.

[0077] The screen panel transfer mechanism 70 is used to temporarily place the screen panel.

[0078] The screen panel transfer mechanism 70 is used for transfer and placement of the screen panel, and its structure is the same as that of the transfer lifting mechanism 62 in the above-mentioned screen panel loading mechanism 60 and will not be elaborated here.

[0079] In an embodiment of the present invention, the screen panel handling mechanism 81 and the following upper lamination platform 82 are both arranged between two cross rails and move along the length direction of the cross rails, and are driven to move by a linear motor in the cross rails. Among them,

[0080] The panel handling mechanism 81 is used to transport the panel from the panel loading mechanism 60 to the panel transfer mechanism 70.

[0081] The panel handling mechanism 81 includes a panel handling frame 811, a plurality of panel handling vacuum suction nozzles 813, a panel handling jig plate 812, and a first vacuum gas storage tank 814. The plurality of panel handling vacuum suction nozzles 813 and the panel handling jig plate 812 are arranged at the lower part of the panel handling frame 811. The two ends of the panel handling frame 811 are mounted on two cross rails and move. The panel handling jig has a plurality of suction holes. The first vacuum gas storage tank 814 is connected to the plurality of panel handling vacuum suction nozzles 813 and the plurality of suction holes of the panel handling jig through pipelines. Through the panel handling jig and the plurality of panel handling vacuum suction nozzles 813, the adsorption and handling of the panel are realized.

[0082] The upper laminating platform 82 is used to adsorb the panel placed on the transfer mechanism and move the panel to the laminating station 403 so that the panel is laminated with the polarizer on the lower laminating platform 41.

[0083] The upper laminating platform 82 includes an upper laminating frame 821, an upper laminating jig plate 822, and a second vacuum gas storage tank 823. The upper laminating jig plate 822 is arranged at the lower part of the upper laminating frame 821. The two ends of the upper laminating frame 821 are mounted on two cross rails and move. The upper laminating jig plate 822 has a plurality of suction holes. The second vacuum gas storage tank 823 is connected to the plurality of suction holes of the upper laminating jig plate 822 through pipelines. Through the upper laminating jig plate 822, the adsorption and handling of the panel are realized.

[0084] In an embodiment of the present invention, when laminating the polarizer and the panel, the upper laminating platform 82 adsorbs the panel and positions it above the laminating station 403 of the laminating mechanism 40, and then the lower laminating platform 41 moves from the film tearing station 402 to the laminating station 403.

[0085] In this embodiment, a polarizer position detection mechanism 42 is further provided on the laminating mechanism 40. The polarizer position detection mechanism 42 is used to detect the position of the polarizer. The polarizer position detection mechanism 42 is located between the film tearing station 402 and the laminating station 403. In addition, the lower laminating platform 41 includes a platform base 411, a laminating plate 412, and a screen plate position detection mechanism 413. The laminating plate 412 is provided above the platform base 411 and is movably connected to the platform base 411 through a movable module. The polarizer is adsorbed on the laminating plate 412. The screen plate position detection mechanism 413 is provided on the side of the platform base 411. The screen plate position detection mechanism 413 is used to detect the position of the screen plate adsorbed on the upper laminating platform 82. By separately detecting the positions of the polarizer and the screen plate through the polarizer position detection mechanism 42 and the screen plate position detection mechanism 413, when the lower laminating platform 41 moves to the laminating station 403, the correction amount is calculated based on the detection results, and then the position of the laminating plate 412 is changed through the movable module of the platform base 411, so that the polarizer on the laminating plate 412 is aligned with the screen plate of the upper laminating platform 82, facilitating subsequent lamination.

[0086] Specifically, the polarizer position detection mechanism 42 includes a polarizer position detection frame body 421 and two polarizer photographing CCDs 422. The polarizer position detection frame body 421 is provided on the laminating mechanism 40, and there is a detection channel between the polarizer position detection frame body 421 and the laminating mechanism 40 for the lower laminating platform 41 to pass through. The two polarizer photographing CCDs 422 are provided on the polarizer position detection frame body 421 and are located above the detection channel. The lenses of the two polarizer photographing CCDs 422 are both arranged downward. When the lower laminating platform 41 initially passes through the detection channel, the two polarizer photographing CCDs 422 respectively photograph two corner points of the polarizer. When the lower laminating platform 41 exits the detection channel, the two polarizer photographing CCDs 422 respectively photograph the other two corner points of the polarizer, photographing a total of four corner points of the polarizer, and thus detecting the position of the polarizer. In this embodiment, one of the polarizer photographing CCDs 422 is movably provided on the polarizer position detection frame body 421, that is, it moves along a direction parallel to the lower laminating platform 41 through a linear motor module provided on the polarizer position detection frame body 421. In this way, the position detection of polarizers of different sizes can be realized, which is more convenient.

[0087] In addition, the above-mentioned panel position detection mechanism 413 is fixedly arranged on the side of the platform base 411. In this embodiment, the panel position detection mechanism 413 is located on the side where the lower laminating platform 41 moves towards the laminating station 403. The panel position detection mechanism 413 includes two panel photographing CCDs, and the lenses of the panel photographing CCDs are arranged upward. When the lower laminating platform 41 moves, the two panel photographing CCDs respectively capture two corner points of the panel, and then capture two corner points on the other side of the panel, thereby detecting the position of the panel. In this embodiment, one of the panel photographing CCDs is movably arranged on the side of the platform base 411, that is, it moves along the direction parallel to the platform base 411 through a linear motor module arranged on the side of the platform base 411. In this way, the position detection of panels of different sizes can be realized, which is more convenient.

[0088] After the detection is completed, the position of the laminating plate 412 is adjusted through the movable module. In one embodiment, the movable module includes an X-axis movement module, a Y-axis movement module, and a rotation module. That is, the laminating plate 412 is translated through the X-axis movement module and the Y-axis movement module, and the angle of the laminating plate 412 is changed through the rotation module, so as to achieve accurate alignment. Specifically, an X-axis driving cylinder is arranged on the platform base 411, the output shaft of the X-axis driving cylinder is connected to the Y-axis driving cylinder, and the output shaft of the Y-axis driving cylinder is connected to the rotation servo motor, thereby realizing the position adjustment of the laminating plate 412 as described above, so that the polarizer and the panel are aligned.

[0089] After the polarizer and the panel are aligned, lamination is carried out. In one embodiment of the present invention, an attaching rubber roller 414 is arranged on the side of the lower laminating platform 41 in the moving direction of the upper laminating platform 82. Specifically, in this embodiment, the attaching rubber roller 414 is arranged on the side of the laminating plate 412. The attaching rubber roller 414 is movably arranged on the side of the lower laminating platform 41, and the attaching rubber roller 414 is located below the end of the polarizer. When the lamination of the polarizer is required, the attaching rubber roller 414 moves upward and attaches the end of the polarizer to the end of the panel, and keeps the position unchanged. The lower laminating platform 41 stops adsorbing the polarizer. As the upper laminating platform 82 moves away from the laminating station 403, the polarizer is pressed by the attaching rubber roller 414, and then is completely laminated on the lower part of the panel to achieve lamination. In this embodiment, the attaching rubber roller 414 is rotatable, so that the wear of the polarizer is avoided and the lamination is easier.

[0090] In this embodiment, a rubber roller plate 416 is provided on the side of the lower laminating platform 41. The attaching rubber roller 414 is rotatably arranged on the rubber roller plate 416. An elevating plate 417 is provided on the side of the lower laminating platform 41. The rubber roller plate 416 is arranged above the elevating plate 417. The elevating plate 417 is lifted and lowered by the elevating screw rod at the bottom and the driving motor. And lifting cylinders are provided at both ends of the elevating plate 417. The output shaft of the lifting cylinder is fixedly connected to the rubber roller plate 416. The attaching rubber roller 414 is lifted and lowered greatly through the elevating screw rod and the driving motor. The attaching rubber roller 414 is ensured to tightly attach the polarizer to the screen plate by the support of the lifting cylinder, so that the lamination is tight.

[0091] In addition, a blocking plate 415 is provided on the lower laminating platform 41. When the polarizer is adsorbed on the lower laminating platform 41, the end of the polarizer is located at the blocking plate 415. The above-mentioned attaching rubber roller 414 is provided below the blocking plate 415. A plurality of blocking cylinders are provided on the side of the lower laminating platform 41. The output shaft of the blocking cylinder is connected to the blocking plate 415. The blocking plate 415 is moved away by the blocking cylinder, so as to facilitate the rising of the attaching rubber roller 414 to attach the polarizer.

[0092] In one embodiment of the present invention, the number of the laminating mechanisms 40 is multiple, and the multiple laminating mechanisms 40 are arranged in parallel. The laminating station 403 of each laminating mechanism 40 is located below the moving path of the upper laminating platform 82.

[0093] In this way, the multiple laminating mechanisms 40 can work alternately, improving the working efficiency. And the laminated screen plates are all discharged through the upper laminating platform 82, which is convenient for collection. In this embodiment, the number of the laminating mechanisms 40 is two, and a waste film placing machine is provided on the side of each laminating mechanism 40, so as to facilitate the storage of the protective film torn off from the polarizer.

[0094] In one embodiment of the present invention, the large-size polarizer laminating machine further includes a blanking and alignment mechanism 601. The upper laminating platform 82 moves the laminated screen plate to the blanking and alignment mechanism 601. The blanking and alignment mechanism 601 is used to align the laminated screen plate and blank it.

[0095] In this embodiment, the blanking and alignment mechanism 601 is the same as the screen plate loading mechanism 60, which will not be described in detail. The transfer lifting mechanism 62 in the blanking and alignment mechanism 601 moves upward to dock with the screen plate adsorbed by the upper laminating platform 82. The transfer lifting mechanism 62 adsorbs the screen plate and moves downward, so that the screen plate is placed on the roller conveying mechanism 61 in the blanking and alignment mechanism 601. Then, the screen plate alignment mechanism 63 and the screen plate stop mechanism 64 in the blanking and alignment mechanism 601 are used to align and limit the screen plate, so as to facilitate subsequent detection and blanking.

[0096] In an embodiment of the present invention, the large-size polarizer laminator further includes an AOI detection mechanism 602, and the AOI detection mechanism 602 is connected to the blanking and alignment mechanism 601. The blanking and alignment mechanism 601 moves the laminated panel to the AOI detection mechanism 602, and the AOI detection mechanism 602 is used to detect the accuracy of the laminated panel.

[0097] The AOI detection mechanism 602 is located below the roller conveying mechanism 61 of the above-mentioned blanking and alignment mechanism 601. Specifically, the AOI detection mechanism 602 includes an AOI detection board and two spaced-apart AOI detection CCDs 6021, and the two AOI detection CCDs 6021 are respectively arranged on both sides of the AOI detection board. The above-mentioned laminated panel moves along with the roller conveying mechanism 61 of the blanking and alignment mechanism 601 and moves above the AOI detection mechanism 602. Then, the two AOI detection CCDs 6021 on both sides first capture the two front corners of the panel, and as the panel moves, capture the two rear corners of the panel. Since the light transmittance of the panel with the polarizer completely laminated and the panel with the polarizer misaligned is different, in this way, the panel with the polarizer not completely laminated can be detected, and the non-compliant panel can be processed.

[0098] In this embodiment, the AOI detection mechanism 602 further includes two spaced-apart AOI detection clamping blocks 6022. When the panel moves along with the roller conveying mechanism 61 of the blanking and alignment mechanism 601, the panel is made to continue moving through the panel stop mechanism 64 of the blanking and alignment mechanism 601. Then, the AOI detection clamping blocks 6022 clamp both sides of the panel to facilitate the AOI detection CCD 6021 to take pictures. In this embodiment, both the AOI detection clamping blocks 6022 and the AOI detection CCD 6021 are arranged on the AOI detection block. Among them, the AOI detection clamping block 6022 includes an upper lifting cylinder and a lower lifting cylinder arranged on the AOI detection block. The upper lifting cylinder and the lower lifting cylinder are arranged oppositely. The output shaft of the upper lifting cylinder extends downward and is connected to an upper clamping block. The output shaft of the lower lifting cylinder extends upward and is connected to a buffer spring. The clamping of both sides of the panel is achieved through the buffer spring and the upper clamping block. And due to the presence of the buffer spring, the panel moves slowly to facilitate the AOI detection CCD 6021 to capture the rear corners of the panel.

[0099] In addition, the above two AOI detection CCDs 6021 are movably arranged on the AOI detection board, and each AOI detection CCD 6021 moves along the length direction of the AOI detection board. Specifically, the AOI detection CCD 6021 is fixed on the AOI detection block. Linear modules and servo motors are arranged on each side of the AOI detection board. The AOI detection block is movably arranged on the linear module. Through the drive of the linear module and the servo motor, the movement of the above AOI detection CCD 6021 is realized, and thus AOI detection can be performed on panel boards of different sizes. At the same time, since the above AOI detection clamping block 6022 is also arranged on the AOI detection block, clamping of panel boards of different sizes can be realized.

[0100] The panel board moves with the roller conveying mechanism 61 of the blanking and alignment mechanism 601. After the AOI detection is completed, it enters the subsequent flipping and blanking mechanism 90.

[0101] In an embodiment of the present invention, the large-size polarizer laminating machine further includes a flipping and blanking mechanism 90. The flipping and blanking mechanism 90 is connected to the AOI detection mechanism 602. The flipping and blanking mechanism 90 is used to flip the panel board after lamination and transport it to the subsequent station.

[0102] The flipping and blanking mechanism 90 includes a bottom frame 91 and a flipping frame 92. Both sides of the flipping frame 92 are rotatably connected to both sides of the bottom frame 91. The flipping frame 92 has an upper flipping roller group 921 and a lower flipping roller group arranged at intervals up and down inside. There is a flipping gap between the upper flipping roller group 921 and the lower flipping roller group. The flipping gap is used for the panel board to pass through. In this way, after the panel board is transported into the flipping gap, by rotating the flipping frame 92 relative to the bottom frame 91, the flipping frame 92 is flipped 180°, so as to realize the overall flipping of the panel board. Then, the panel board is transported to the subsequent station through the upper flipping roller group 921 after flipping, so as to facilitate subsequent processing. Only one side of the flipping frame 92 has a flipping entrance and exit communicating with the flipping gap. The flipping entrance and exit is used to connect with other processes. The panel board enters from the flipping entrance and exit to facilitate the entry of the panel board. After flipping, it exits from the flipping entrance and exit. Only setting the flipping entrance and exit on one side can prevent the panel board from falling out of the flipping frame 92 during the flipping process. Of course, in other embodiments, the flipping frame 92 may be provided with a flipping entrance and a flipping exit on both sides respectively, which will not be elaborated here. The roller conveying mechanism 61 in the above blanking and alignment mechanism 601 is butted with the lower flipping roller group; and the roller conveying mechanism 61 is flush with the lower flipping roller group to ensure the stable transportation of the panel board into the flipping frame 92.

[0103] In addition, the upper flipping roller group 921 has a plurality of upper flipping roller rows arranged at intervals, and the lower flipping roller group has a plurality of lower flipping roller rows arranged at intervals. The upper flipping roller rows and the lower flipping roller rows are arranged opposite to each other. The upper flipping roller row includes an upper flipping roller rod and a plurality of upper flipping rollers, and the plurality of upper flipping rollers are sleeved on the upper flipping roller rod. The lower flipping roller row includes a lower flipping roller rod and a plurality of lower flipping rollers, and the plurality of lower flipping rollers are sleeved on the lower flipping roller rod. The upper flipping rollers and the lower flipping rollers are arranged opposite to each other. In this way, scratches on the screen panel caused by the staggered arrangement of the upper flipping rollers and the lower flipping rollers are avoided, and the stable transportation of the screen panel is ensured.

[0104] In this embodiment, the lower flipping roller group rotates synchronously to convey the screen panel. Similarly, the lower flipping roller group does the same. Moreover, the upper flipping roller group 921 and the lower flipping roller group rotate non-synchronously. Specifically, before flipping, the lower flipping roller group first conveys the screen panel into the flipping frame 92, then flips, and then the upper flipping roller group 921 conveys it out of the flipping frame 92. Specifically, an upper flipping synchronous rod 927 is provided on the side of the flipping frame 92. A plurality of upper flipping synchronous magnetic wheels 9271 are sleeved on the upper flipping synchronous rod 927. An upper flipping magnetic wheel 9211 is sleeved on the end of each upper flipping roller rod. The upper flipping synchronous magnetic wheel 9271 is docked with the upper flipping magnetic wheel 9211. The upper flipping synchronous rod 927 is driven to rotate by a synchronous servo motor 928 provided on the side of the flipping frame 92. Similarly, the lower flipping roller group will not be elaborated here. Through the above structure, the separate synchronous rotation of the upper flipping roller group 921 and the lower flipping roller group is realized.

[0105] In addition, an adsorption assembly is further provided on the flipping frame 92. The adsorption assembly includes an adsorption frame 922 and a plurality of flipping vacuum suction nozzles 923. The plurality of flipping vacuum suction nozzles 923 are provided on the adsorption frame 922 and are arranged downward. The plurality of flipping vacuum suction nozzles 923 are located in the gaps between the upper flipping roller groups 921. After the screen panel is conveyed into the flipping frame 92, the screen panel is adsorbed and fixed by the flipping vacuum suction nozzles 923 of the adsorption assembly, and then rotated to achieve flipping, ensuring the stable flipping of the screen panel and preventing it from falling out or moving randomly. Further, a plurality of lifting cylinders are provided on the adsorption frame 922. The output shaft of the lifting cylinder is fixedly connected to the flipping vacuum suction nozzle 923. The lifting and moving of the flipping vacuum suction nozzle 923 are realized through the lifting cylinder to ensure that the flipping vacuum suction nozzle 923 contacts and adsorbs the screen panel.

[0106] In this embodiment, a flipping servo motor 926 is provided on one side of the chassis 91. The flipping servo motor 926 is connected to a speed reducer, and the speed reducer is connected to one side of the flipping frame 92. The flipping of the flipping frame 92 is realized by the flipping servo motor 926. The other side of the flipping frame 92 is rotatably arranged on the other side of the chassis 91, and the other side of the flipping frame 92 extends out of the chassis 91 to form a limit disk 925. A plurality of photoelectric sensors are provided on the other side of the chassis 91, and the plurality of photoelectric sensors are arranged around the limit disk 925. An induction piece extends out from the side of the limit disk 925, and the induction piece is used to pass through the photoelectric sensors. By rotating the induction piece of the limit disk 925 to different photoelectric sensors, feedback braking during the flipping of the flipping frame 92 is realized.

[0107] In the embodiment of the present invention, the screen panel handling mechanism 81 transports the screen panel on the screen panel loading mechanism 60 to the screen panel transfer platform 70, and the upper laminating platform 82 moves the screen panel to the laminating station 403. Compared with a single handling mechanism, in the large-size TP transfer device provided by the present invention, the screen panel handling mechanism 81 and the upper laminating platform 70 can work simultaneously, with high handling efficiency and improved production efficiency. In addition, since the screen panel handling mechanism 81 and the upper laminating platform 70 move between the same two cross rails, there is no need to change the orientation of the screen panel, and the production efficiency is high.

[0108] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
