[0025] In this embodiment, as Figure 1 shown, the frame 100 can adopt an existing frame type structure. The loading platform 200, the material taking platform 300, and the fixture 400 are all arranged on the frame 100. At this time, it is preferably that the loading surfaces of the loading platform 200 and the fixture 400 are located in the same horizontal plane, so as to facilitate the material taking platform 300 to transport the soft substrate on the loading platform 200 to the hard substrate on the fixture 400 and perform lamination. Among them, the loading platform 200 is set with reference to an existing material transportation device, as long as it can place the soft substrate, and the fixture 400 only needs to have a receiving cavity adapted to the hard substrate. At the same time, a plurality of vacuum suction holes can be arranged at the bottom of the receiving cavity to facilitate fixing the hard substrate in the receiving cavity.

[0026] The optimization of this solution lies in the structure of the material taking platform 300. As Figure 1 and Figure 2 shown, specifically, the material taking platform 300 includes a first mounting frame 310, a first driving mechanism 320, a tensioning device 330, a sticking film 340, a laminating device 350, and a second driving mechanism 360. Among them,

[0027] As Figure 2 and Figure 3As shown, the first mounting frame 310 includes a first top plate 311 and first side plates 312 arranged on opposite sides of the first top plate 311, and the two first side plates 312 are respectively slidably connected to the frame 100. Specifically, the first side plate 312 can be connected to the frame 100 through a linear guide rail, and the material platform and the fixture 400 are located in the moving area between the two first side plates 312.

[0028] like Figure 2 As shown, the first driving mechanism 320 is arranged on the frame 100, and the output end of the first driving mechanism 320 is connected to the first side plate 312, so as to drive the first mounting frame 310 to reciprocate between the loading platform 200 and the fixture 400. At this time, the first driving mechanism 320 is preferably a motor screw assembly, and the number of the first driving mechanism 320 is two, which are respectively connected to the two first side plates 312 in transmission.

[0029] like Figure 3 As shown, the adhesive film 340 is horizontally arranged on the first mounting frame 310, and the two ends of the adhesive film 340 are respectively connected to the first mounting frame 310 and the output end of the tensioning device 330. The adhesive film 340 is preferably a rectangular flexible sheet made of PET, and the bottom surface of the adhesive film 340 has an adhesive layer, which can be directly provided as a tape layer or a specific glue coated on the bottom surface of the adhesive film 340, and the adhesive strength of the adhesive layer to the soft substrate on the loading platform 200 is smaller than the adhesive strength of the soft substrate to the hard substrate on the fixture 400.

[0030] The tensioning device 330 can be in the form of a storage tube and a torsion spring. In this case, the storage tube is rotatably arranged on the first mounting frame 310, and the torsion spring is sleeved on the rotating shaft of the storage tube and connected to the first mounting frame 310 and the storage tube respectively, and one end of the adhesive film 340 is wound around the storage tube, so that the elastic force of the torsion spring can be used to control the length of the other end of the adhesive film 340, so as to achieve the purpose of controlling the tightness of the adhesive film 340. Of course, it is also possible to directly use a linear drive mechanism on the first mounting frame 310 to connect with one end of the adhesive film 340, so as to achieve the purpose of controlling the tightness of the adhesive film 340 by controlling the distance between the two ends of the adhesive film 340.

[0031] like Figure 3 and Figure 4As shown, the laminating device 350 is disposed on the first mounting bracket 310. The laminating device 350 includes a second mounting bracket 351, a laminating roller 352, and a third driving mechanism 353. At this time, the second mounting bracket 351 includes a second top plate 357 and two second side plates 358 disposed on opposite sides of the second top plate 357. The second top plate 357 is slidably disposed on the top surface of the first top plate 311. Specifically, the second top plate 357 may be connected to the first top plate 311 through a linear guide rail, and the second top plate 357 can slide along the length direction of the adhesive film 340. The two second side plates 358 are located on both sides of the first side plate 312, so that the connection line between the two first side plates 312 and the connection line between the two second side plates 358 are arranged in a perpendicular state. Both ends of the laminating roller 352 are slidably connected to the two second side plates 358 through first connection blocks 354, and both ends of the laminating roller 352 are rotatably connected to the two first connection blocks 354. At the same time, the laminating roller 352 is located above the adhesive film 340 and below the first top plate 311. The number of the third driving mechanisms 353 is preferably two, which are respectively disposed on the two second side plates 358 and are in transmission connection with the first connection blocks 354. The third driving mechanism 353 preferably adopts a linear cylinder, so as to conveniently drive the laminating roller 352 to approach or move away from the adhesive film 340.

[0032] As Figure 2 and Figure 3 shown, the second driving mechanism 360 is disposed on the first top plate 311, and the output end of the second driving mechanism 360 is connected to the second top plate 357 to drive the second top plate 357 to move. As for the form of the second driving mechanism 360, a motor screw assembly can be used.

[0033] In this embodiment, when the automatic film laminating machine is working, it includes a material taking part and a laminating part. The material taking part: First, the first driving mechanism 320 drives the first mounting frame 310 to slide and makes the adhesive film 340 located directly above the loading platform 200. Then, the second driving mechanism 360 drives the laminating roller 352 to be located directly above one end of the soft substrate. Again, the third driving mechanism 353 drives the laminating roller 352 to move towards the adhesive film 340 and drives the adhesive film 340 to contact the soft substrate. Finally, the second driving mechanism 360 drives the laminating roller 352 to move from one end of the soft substrate towards the other end, so as to paste the soft substrate on the adhesive film 340 and then the third driving mechanism 353 drives the laminating roller 352 to rise, thus completing the material taking action. The laminating part: The first driving mechanism 320 drives the first mounting frame 310 to move towards the fixture 400 and makes the soft substrate on the adhesive film 340 located directly above the fixture 400. Since the laminating roller 352 is located at one end of the soft substrate at this time, that is, the third driving mechanism 353 is used to directly drive the laminating roller 352 to move towards the adhesive film 340, and after a part of the soft substrate located on the adhesive film 340 contacts the hard substrate located on the fixture 400, the second driving mechanism 360 is used to drive the laminating roller 352 to move towards the other end of the soft substrate, so as to complete the laminating action. At the same time, since the adhesive film 340 has a certain deformation performance, during the process of the laminating roller 352 contacting the adhesive film 340, the tensioning device 330 is used to control the tightness of the adhesive film 340, so that the adhesive film 340 can better contact the soft substrate. In this embodiment, by arranging the loading platform 200, the material taking platform 300 and the fixture 400 on the frame 100, and using the material taking platform 300 to transport the soft substrate on the loading platform 200 to the surface of the hard substrate located on the fixture 400 for laminating by means of pasting, it is beneficial to transport and laminate soft substrates of any shape, thereby increasing the applicable range of the automatic film laminating machine. At the same time, rolling the laminating roller 352 on the adhesive film 340 to laminate the soft substrate on the hard substrate is beneficial to avoiding the phenomenon of scratching when the laminating roller 352 directly rolls on the soft substrate.

[0034] In a preferred embodiment, as Figure 2 and Figure 3As shown in the figure, the tensioning device 330 includes a fourth driving mechanism 331 disposed on the first mounting bracket 310 and a first guiding cylinder 332 rotatably disposed on the first mounting bracket 310. At this time, it is preferred that the fourth driving mechanism 331 is located on the first side plate 312. The fourth driving mechanism 331 is a linear driving mechanism, and the output end of the fourth driving mechanism 331 needs to be arranged in a vertical state. The type that the fourth driving mechanism 331 can adopt can be a motor screw assembly or a linear cylinder. It is preferred that the first guiding cylinder 332 is arranged in the same direction as the laminating roller 352. At the same time, it is preferred that both ends in the length direction of the adhesive film 340 are provided with second connecting blocks 341, and the two second connecting blocks 341 are respectively connected to the first mounting bracket 310 (i.e., the two first side plates 312), and one end of the second connecting block 341 is slidably connected to the first mounting bracket 310 and can slide in the vertical direction. At the same time, the slidably arranged second connecting block 341 is connected to the output end of the fourth driving mechanism 331. At this time, the slidably arranged second connecting block 341 and the first guiding cylinder 332 are located on the same first side plate 312, and the first guiding cylinder 332 is located directly below the second connecting block 341. As for the form of the second connecting block 341, it can be composed of two plate bodies with the same width as the adhesive film 340. By placing the end of the adhesive film 340 between the two plate bodies and using screws to fix the two plate bodies, it is convenient for both ends of the adhesive film 340 to be respectively connected to one of the first side plates 312 and the output end of the fourth driving mechanism 331 through the second connecting blocks 341. At this time, the first guiding cylinder 332 can be attached to the top surface of the adhesive film 340, so as to facilitate the fourth driving mechanism 331 to drive the second connecting block 341 to move to control the tightness of the adhesive film 340.

[0035] In a preferred embodiment, in order to facilitate the control of the tightness of the adhesive film 340, it is preferred that the fourth driving mechanism 331 is a linear cylinder, and a pressure regulating valve for controlling the air pressure entering the linear cylinder is also provided, so as to facilitate the control of the speed of the output end of the linear cylinder.

[0036] In a preferred embodiment, as Figure 3 and Figure 4 shown, in order to facilitate the position of the adhesive film 340 during material taking and laminating, it is preferred that the laminating device 350 further includes a second guiding cylinder 355 whose two ends are respectively rotatably connected to the two first connecting blocks 354. The second guiding cylinder 355 is arranged in the same direction as the laminating roller 352, and the second guiding cylinder 355 is located below the adhesive film 340 and can be attached to the bottom surface of the adhesive film 340. At this time, the laminating roller 352 can be attached to the top surface of the adhesive film 340 and is located below the second guiding cylinder 355. In this embodiment, when the laminating roller 352 controls the actions of taking and laminating the adhesive film 340, that is, when there is no third driving mechanism 353 driving the laminating roller 352 to move towards the adhesive film 340, the adhesive film 340 can be driven to move.

[0037] In a preferred embodiment, as Figure 4 shown, limiting rings 356 are respectively arranged at two ends of the second guiding roller, and the two limiting rings 356 are respectively attached to opposite side edges of the adhesive film 340, that is, the distance between the two limiting rings 356 is equal to the width of the adhesive film 340, which is beneficial to controlling the position of the adhesive film 340 when the laminating roller 352 moves on the adhesive film 340.

[0038] In a preferred embodiment, as Figure 2 and Figure 5 shown, the load platform 200 includes a first carrier plate 210 and a fifth driving mechanism 220. A plurality of vacuum suction holes are evenly arranged on the top surface of the first carrier plate 210, so as to facilitate fixing the flexible substrate on the first carrier plate 210, which is beneficial to preventing the flexible substrate from moving on the first carrier plate 210. At this time, the fifth driving mechanism 220 is located on the frame 100, and the output end of the fifth driving mechanism 220 is in transmission connection with the first carrier plate 210, so as to facilitate driving the first carrier plate 210 to rotate horizontally. The specific driving mode of the fifth driving mechanism 220 can refer to the existing mode, such as a stepping motor or a servo motor. In this embodiment, the first carrier plate 210 is driven to rotate by the fifth driving mechanism 220, which is beneficial to adjusting the placement angle of the flexible substrate on the first carrier plate 210, so as to improve the lamination accuracy of the flexible substrate and the rigid substrate. At the same time, as Figure 1 shown, in order to facilitate the angle of rotation of the first carrier plate 210 driven by the fifth driving mechanism 220, it is preferably that a first CCD assembly 500 is further arranged on the frame 100, so as to analyze the deviation degree between the flexible substrate and the rigid substrate after photographing the flexible substrate on the first carrier plate 210 by using the first CCD assembly 500, and then drive the rotation angle of the first carrier plate 210 by the fifth driving mechanism 220 according to the deviation degree information.

At this time, it is preferably that the positions where the two ends of the rotating shaft are connected are respectively the centers of the bottom surface of the first carrier plate 210 and the top surface of the second carrier plate 221.

Specifically, the first linear slide rail 222 can be located on the bottom surface of the first carrier plate 210, and the second linear slide rail 223 can be located on the bottom surface or side surface of the second carrier plate 221.

At this time, it is preferably that the first linear slide rail 222 and the second linear slide rail 223 are respectively located at the same end of the first carrier plate 210 and the second carrier plate 221, so as to facilitate controlling the rotation angle of the first carrier plate 210. The lead screw 224 is provided on the second carrier plate 221, and the lead screw 224 is arranged in the same direction as the second linear slide rail 223. At the same time, the nut in the lead screw 224 is connected to the slider in the second slide rail. The motor is provided on the second carrier plate 221, and the output end of the motor is in transmission connection with the lead screw 224. Preferably, the motor is a servo motor or a stepper motor. In this embodiment, the motor drives the nut in the lead screw 224 to move, so as to drive the slider in the first linear slide rail 222 to move by using the nut, and then drive the slider in the second linear slide rail 223 to move, thereby driving the first carrier plate 210 to rotate.

[0040] In a preferred embodiment, as Figure 5 and Figure 6As shown, the load platform 200 further includes a sixth driving mechanism 230 for driving the first carrier plate 210 to move horizontally.

Among them, preferably, the first driving component and the second driving component can adopt the existing linear guide rail + lead screw assembly arrangement. Specifically, preferably, there are two sixth driving mechanisms 230, which are arranged oppositely on the bottom surface of the second carrier plate 221. At this time, the first driving component includes a third carrier plate and a third linear slide rail arranged on the top surface of the third carrier plate, and the slider in the third linear slide rail is connected to the bottom surface of the second carrier plate 221. The second driving component includes a fourth carrier plate and a fourth linear slide rail arranged on the top surface of the fourth carrier plate, and the slider in the fourth linear slide rail is connected to the bottom surface of the third carrier plate. At the same time, a fifth carrier plate and two motor lead screw assemblies arranged on the fifth carrier plate are also provided. The fourth carrier plate is located on the fifth carrier plate, and the output ends of the two motor lead screw assemblies are respectively connected to one of the third carrier plate and the fourth carrier plate, so as to automatically drive the first carrier plate 210 to move in the horizontal plane, thereby adjusting the position of the soft substrate located on the first carrier plate 210.

[0041] In a preferred embodiment, as Figure 5 shown, the load platform 200 further includes a seventh driving mechanism 240 for driving the first carrier plate 210 to move closer to or farther away from the adhesive film 340.

Of course, the linear cylinder can also be replaced with a motor lead screw assembly, so as to more conveniently and accurately control the height of the first carrier plate 210. The specific connection method can be referred to the existing method.

[0042] In a preferred embodiment, as Figure 7As shown in the figure, the first CCD component 500 includes an imaging module 510, an eighth driving mechanism 520, and a ninth driving mechanism 530.

[0043] In a preferred embodiment, as Figure 1 shown in the figure, a second CCD component 600 can also be arranged on the frame 100, and the second CCD component 600 is located directly above the fixture 400, so that the position of the hard substrate on the fixture 400 can be obtained by using the second CCD component 600, which provides a basis for the fifth driving mechanism 220 to adjust the angle of the soft substrate located on the first carrier 210, so as to position the soft substrate. At this time, the second CCD component 600 can be arranged with reference to the form of the first CCD component 500 and will not be described in detail here.

[0044] In a preferred embodiment, in order to facilitate limiting the positions of the above-mentioned components during linear movement, it is preferable to provide photosensitive films on each linearly movable component, and two photoelectric switches are arranged at intervals on the component carrying the sliding component, so that the movement range of the movable component can be controlled within the two photoelectric switches. Specifically, taking the first CCD component 500 as an example for specific description, the remaining components can be arranged with reference to the following form. For example, the eighth driving mechanism 520 is connected to the frame, and the ninth driving mechanism 530 is connected to the output end of the eighth driving mechanism 520, and the output end of the ninth driving mechanism 530 is connected to the imaging module 510. At this time, two first photoelectric switches are arranged on the eighth driving mechanism 520, and a first photosensitive film cooperating with the two first photoelectric switches is arranged on the ninth driving mechanism 530, so as to limit the movement range of the ninth driving mechanism 530 between the two first photoelectric switches. At the same time, two second photoelectric switches can also be arranged on the ninth driving mechanism 530, and a second photosensitive film cooperating with the two second photoelectric switches is arranged on the imaging module 510, so as to limit the movement range of the imaging module between the two second photoelectric switches.

[0045] It should be noted that the optimal solutions of the above-mentioned automatic film laminating machines all meet the requirements of applying AGR films and sensor films to 3D glass and P covers during the film laminating task. At the same time, it also meets the requirements of film laminating for single-screen, double-screen, and multi-screen 3D covers. For example, ASF / OCA lamination: covers all laminations such as S-type, C-type, V-type, etc.; for V-type products, it can be ≥120°, CG / TP: 1500mm * 300mm * 100mm (length * width * arc height / warp); for CG / TP, the curvature is above R300mm, the lamination size is ≤ L1500mm * W400mm, the minimum arc radius of the cover is R ≥ 150mm, the included angle is 145 - 180 degrees, meeting the laminations of shapes such as V-shaped, Z-shaped, S-shaped, etc., and the lamination accuracy is ±0.10mm.
