Description

Technical Field

[0001] The present invention relates to the technical field of film laminating equipment, and in particular to a single-sided film laminating machine for a substrate. Background Art

[0002] With the rapid development of the electronics manufacturing industry, substrate lamination plays an increasingly important role in the production of electronic products. Substrate lamination involves applying a protective or functional film to the surface of a substrate. It is widely used in liquid crystal displays, touch screens, semiconductors, and other fields. Lamination quality directly impacts product performance and appearance, placing increasing demands on the precision and efficiency of lamination equipment.

[0003] At present, the common substrate laminating machines on the market are mainly divided into three types: manual, semi-automatic and fully automatic. Among them, fully automatic laminating machines are widely used in large-scale production due to their high efficiency and good precision. CN105383730B discloses a laminating machine suitable for ultra-thin and lightweight glass substrates, which includes a frame base with a slide rail, a lifting film pressing mechanism arranged across the top of the frame base, a linear sliding film laminating platform and a flip film carrying mechanism, which realizes the function of laminating and pressing the film at the same time. CN114735275A discloses a fully automatic BG film laminating machine, which is internally provided with a loading and unloading mechanism, a film feeding mechanism, a film stretching mechanism, a film pressing mechanism and a cutting mechanism, which can complete the fully automated process of placing, laminating and removing wafers.

[0004] During the film laminating process, the transport and handling of film materials are key steps. The film laminating machine disclosed in CN111710622A includes a film laminating device, a film cutting device, a film feeding mechanism for conveying dry film, and a film pulling mechanism for pulling the dry film, enabling automatic conveying, automatic laminating, and automatic cutting of dry film. CN115009582B, on the other hand, proposes an automated film laminating device that achieves automated film laminating by installing film laminating mechanisms on both the unloading and loading conveyor belt assemblies. It also utilizes two material transfer clamping assemblies on a linear slide to simultaneously grasp two jigs, allowing the two jigs to be operated separately during film laminating, thereby improving production efficiency.

[0005] For the lamination of films on substrates with special shapes, CN112060561B discloses a lamination method and device, including a workbench, a pre-lamination mechanism, a strong pressing mechanism, a transportation mechanism, and an arc-shaped lamination mechanism, which is particularly suitable for lamination of films on products with curved surfaces such as mobile phones.

[0006] However, there are still some problems with the substrate laminating machines in the existing technology: First, in terms of substrate positioning, the existing laminating machines often use simple mechanical positioning methods, which are difficult to meet the needs of high-precision laminating, resulting in quality problems such as laminating position offset and bubble generation; Second, the existing laminating machines have a single loading and unloading method and poor flexibility, and cannot be adjusted according to actual production needs, affecting production efficiency; Third, the existing laminating machines are difficult to achieve precise deviation correction and uniform pressure distribution of the substrate during the laminating process, resulting in uneven laminating or wrinkles; Finally, the structural design of the existing laminating machines is not reasonable enough, the operation is complicated, and maintenance is difficult, which increases production and maintenance costs.

[0007] Especially for substrates requiring single-sided lamination, existing technologies lack efficient equipment specifically designed for this purpose. Most laminators fail to effectively address issues such as substrate flipping, positioning, and laminating during the lamination process, resulting in low lamination efficiency. Furthermore, existing laminators have poor adaptability when processing substrates of varying sizes and materials, requiring frequent parameter adjustments, increasing operational difficulty and time costs.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0056] In the description of the present application, “plurality” means two or more, unless otherwise clearly defined.

[0057] See Figure 1-27 A single-sided film laminating machine for substrates includes a conveying mechanism 1, a first feeding mechanism 2, a second feeding mechanism 3, an initial positioning mechanism 4, a film pressing mechanism 5 and a film laminating mechanism 6.

[0058] The conveying mechanism 1 includes a first drive module 11 and a second drive module 12 arranged in parallel. The film pressing mechanism 5 is mounted between the first and second drive modules 11, 12 and is slidably connected to the first and second drive modules 11, 12, respectively. The initial positioning mechanism 4 is disposed between the first and second drive modules 11, 12 and is located on one side of the film pressing mechanism 5.

[0059] The first feeding mechanism 2 is provided on one side of the conveying mechanism 1 and is used to transfer the substrate 9 from the initial positioning mechanism 4 to the film pressing mechanism 5. The second feeding mechanism 3 is provided on the other side of the conveying mechanism 1 and is used to transfer the substrate 9 from the film pressing mechanism 5 to the initial positioning mechanism 4 for unloading. The film laminating mechanism 6 is provided on the conveying mechanism 1 and is located on the other side of the film pressing mechanism 5.

[0060] When the film laminating machine is working, the substrate 9 to be laminarized is manually placed on the initial positioning mechanism 4 for preliminary positioning. After the preliminary positioning is completed, the first feeding mechanism 2 is used to clamp and transfer the substrate 9 to the film pressing mechanism 5. The film pressing mechanism 5 is precisely positioned and fixed by vacuum adsorption (the edge positions on both sides of the substrate 9 are grasped by the visual positioning system 8 to adjust the angle and accuracy, combined with vacuum adsorption fixation). Then, the film pressing mechanism 5 slides along the first driving module 11 and the second driving module 12 to the bottom of the film laminating mechanism 6, and the film laminating mechanism 6 performs film lamination. After the film lamination is completed, the film pressing mechanism 5 is reset along the conveying mechanism 1, and the second feeding mechanism 3 is used to clamp and transfer the substrate 9 with the film lamination for unloading. Since the film laminating machine in this technology adopts the setting of loading and unloading on the same side, the first feeding mechanism 2 can be used for loading and unloading, and the second feeding mechanism 3 can be used for unloading and loading, and can even be used crosswise or alone according to the loading situation.

[0061] The initial positioning mechanism 4 includes a first base 41, a positioning platform 42, a first lifting and receiving mechanism 43 and a plurality of positioning components 44. The positioning platform 42 is arranged on the upper end surface of the first base 41. The first lifting and receiving mechanism 43 is arranged in the first base 41, and the positioning platform 42 extends from its upper end to receive the substrate 9. The positioning components 44 are all arranged in the first base 41, and each positioning component 44 is evenly arranged around the first lifting and receiving mechanism 43 to adjust the position of the substrate 9. The upper end surface of the positioning platform 42 is provided with a plurality of evenly distributed support columns 45, and the top end of each support column 45 is provided with a rolling ball, and each ball is located in the same horizontal plane, which is convenient for sliding on the positioning platform 42 when adjusting the position of the substrate 9, thereby reducing the defective rate.

[0062] Specifically, during the initial positioning, the substrate 9 is manually placed on the first lifting and receiving mechanism 43, and the first lifting and receiving mechanism 43 is used to slowly lower the substrate 9 to the positioning platform 42, and then the positioning components 44 located at the four edges of the substrate 9 are used to position the substrate 9 to the pre-center position of the positioning platform 42. After the initial positioning is completed, the first lifting and receiving mechanism 43 supports the substrate 9 to rise, so that the first feeding mechanism 2 or the second feeding mechanism 3 can clamp the substrate 9 located on the positioning platform 42 and transfer it to the film pressing mechanism 5.

[0063] Four positioning assemblies 44 are provided, each comprising a first cylinder 441, a drive frame 442, and a set of limiting rods 443. Each limiting rod 443 is vertically fixed to each end of the drive frame 442. The first cylinder 441 is fixed within the base, and the drive frame 442 is disposed at the power output end of the first cylinder 441. The drive frame 442 can move horizontally to adjust the position of the substrate 9. The limiting rod 443 comprises a limiting rod 443, a sleeve 444, and a set of bearings 445. The sleeve 444 is sleeved around the outer periphery of the limiting rod 443, and the bearings 445 are sleeved between the sleeve 444 and the limiting rod 443 to allow the sleeve 444 to rotate relative to the limiting rod 443. Specifically, during the initial positioning, the visual positioning system 8 grasps the edge positions on both sides of the substrate 9 to adjust the angle and accuracy. During the adjustment, the first cylinders 441 at different positions are started according to the information fed back by the visual positioning system 8 to drive the limit rods 443 to move while pushing the substrate 9 to move in the direction that needs to be adjusted. Since positioning components 44 are provided on the four edges of the substrate 9, the first cylinders 441 at different positions can be started synchronously to work, and the substrate 9 is pushed to the pre-center position of the positioning platform 42 and then limited and fixed by the four limit rods 443 to complete the initial positioning. Furthermore, the limit rods 443 with the above structure are convenient for sliding on the platform when the positioning component 44 is used to push the substrate 9 to move, which can effectively reduce the friction between the edge of the substrate 9 and the sleeve 444 to avoid damage to the substrate 9.

[0064] The lamination mechanism 5 includes a vacuum suction mechanism 51 and a deflection correction and clamping mechanism 52. The vacuum suction mechanism 51 is mounted between the first drive module 11 and the second drive module 12 and is slidably connected to each of the first and second drive modules 11 and 12. Four deflection correction and clamping mechanisms 52 are provided, one on each side of the vacuum suction mechanism 51, to adjust the position of the substrate 9 placed on the vacuum suction mechanism 51.

[0065] The vacuum suction mechanism 51 includes a second base 511, a suction mechanism 512, and a second lifting and receiving mechanism 520. The suction mechanism 512 is disposed on the upper end surface of the second base 511. The second lifting and receiving mechanism 520 is disposed on the second base 511 and is located below the suction mechanism 512. The upper end of the second lifting and receiving mechanism 520 can extend out of the suction mechanism 512 to receive the substrate 9.

[0066] Specifically, when performing the correction and fixation, the first feeding mechanism 2 or the second feeding mechanism 3 is used to place the substrate 9 on the second lifting and receiving mechanism 520, and the second lifting and receiving mechanism 520 is used to slowly lower the substrate 9 to the film laminating platform 513, and then the correction and pressing mechanisms 52 located at the four edges of the substrate 9 are used to correct the edges of the substrate 9 to the pre-centered position of the adsorption mechanism 512 and press and use negative pressure to suck the substrate 9. After the correction and pressing are completed, the film laminating mechanism 6 of the film laminating machine is cooperated to perform film laminating. After the film laminating is completed, the first lifting and receiving mechanism 43 or the second lifting and receiving mechanism 520 is used to support the substrate 9 to lift it up to facilitate clamping the substrate 9 located on the film laminating platform 513 and transfer it to the film pressing mechanism 5.

[0067] Both the first lifting and supporting mechanism 43 and the second lifting and supporting mechanism 520 include a fixed frame 431, a second cylinder 432, and a plurality of ejector pins 433.

The fixed frame 431 is disposed within the first base 41 or the second base 511, and each ejector pin 433 extends through the positioning platform 42 or the adsorption mechanism 512. The second cylinder 432 is disposed at the lower end surface of the first base 41 or the second base 511 and is drivingly connected to the bottom of the fixed frame 431. The second cylinder 432 can drive the fixed frame 431 to rise and fall.

The air channels 515 are all connected to the corresponding airflow ducts 516. The film-laminating platform 513 is sealed and encapsulated between the upper end surface of the negative pressure platform 514 and the negative pressure platform 514 to form a negative pressure cavity. The negative pressure platform 514 is provided with a number of evenly distributed suction nozzles 517. One end of the suction nozzle 517 is connected to the negative pressure cavity. The upper end of the second lifting support mechanism 520 can extend through the film-laminating platform 513 to support the substrate 9. A negative pressure suction pipe 518 is also provided below the second base 511. One end of the negative pressure suction pipe 518 is connected to the airflow duct 516, and the other end of the negative pressure suction pipe 518 is connected to an external negative pressure machine to generate negative pressure.

The fixed plate 521 is fixed to the four sides of the second base 511 and is used to adjust the position of the substrate 9 placed on the film-applying platform 513. When the deviation correcting and pressing mechanism 52 is working: the sensor 519 can also detect the height between the suction nozzle 517 and the substrate 9, and the height between the suction nozzle 517 and the substrate 9 can be adjusted by the pressing plates 535 at different positions to ensure that the substrate 9 is in the same horizontal plane. During the specific adjustment, the first driving device 533 drives the deviation correcting mounting seat 522 and the pressing plate 535 to move together in the horizontal direction, which can be away from the axis of the film sticking platform 513 or close to the axis of the film sticking platform 513. The pressing plate 535 is away from the film sticking platform 513. 3 is located at the axis of the film laminating platform 513, which is convenient for placing the substrate 9 on the film laminating platform 513. When the pressing plate 535 is close to the axis of the film laminating platform 513, the pressing plate 535 can be used to press the four edges of the substrate 9 (the second driving device 534 drives the pressing plate 535 to move vertically downward along the side wall of the correction mounting seat 522 to press the substrate 9). Conversely, after the film laminating is completed, the first driving device 533 and the second driving device 534 can be reset respectively, and the first lifting receiving mechanism 43 can be used to lift the substrate 9 with the film laminating completed to facilitate its transfer and unloading.

[0070] The first feeding mechanism 2 and the second feeding mechanism 3 both include a third driving module 21, a fourth driving module 22, a module mounting frame 23, and a clamping mechanism 24. The third driving module 21 is arranged on one side of the first driving module 11 or the second driving module 12, and the module mounting frame 23 is slidably arranged on the third driving module 21, and the third driving module 21 can drive the module mounting frame 23 to move along the direction of movement of the substrate 9. The fourth driving module 22 is vertically fixed on the module mounting frame 23, and the clamping mechanism 24 is slidably sleeved on the fourth driving module 22 and is located above the initial positioning mechanism 4 or the film pressing mechanism 5. The fourth driving module 22 can drive the clamping mechanism 24 to move upward or downward in the vertical direction. The clamping mechanism 24 includes a clamping claw mounting frame 241 and four groups of clamping components. The clamping components are arranged in pairs on the clamping claw mounting frame 241 to clamp the four edges of the substrate 9. The clamping assembly includes a third cylinder 242 and a group of clamping jaws 243. The third cylinder 242 is fixed to the clamping jaw mounting frame 241. The clamping jaws 243 are arranged at the power output end of the third cylinder 242. The third cylinder 242 can drive the clamping jaws 243 to clamp the substrate 9.

[0071] The film laminating mechanism 6 includes a pre-laminating mechanism 61, an unwinding film assembly 62, a waste film collection assembly 63, a tensioning roller assembly 64, a negative pressure guide wheel 65, and a machine frame 66. These mechanisms are all mounted within the machine frame 66. The waste film collection assembly 63 is located at the top of the machine frame 66, the pre-laminating mechanism 61 is located at the bottom of the machine frame 66, the unwinding film assembly 62 is located below the waste film collection assembly 63, the tensioning roller assembly 64 is located between the pre-laminating mechanism 61 and the unwinding film assembly 62, and the negative pressure guide wheel 65 is located below the pre-laminating mechanism 61. A heated pressure roller 67 is located on one side of the negative pressure guide wheel 65. A back pressure roller pressing assembly 68 is also located on the other side of the heated pressure roller 67. This back pressure roller pressing assembly 68 is movable downward or upward relative to the machine frame 66. An air cavity assembly 69 is also provided on the machine base frame 66, and the air cavity assembly 69 is connected to the pre-film laminating mechanism 61 and the negative pressure guide wheel 65 through pipes. A dry film air conditioner 70 is also provided above the waste film collection group 63; the waste film collection group 63 is provided with a film material roller 631 and a waste material collection roller 632, and the film material roller 631 and the waste material collection roller 632 are both mounted on the machine base frame 66, and the waste material collection roller 632 is located above the film material roller 631 and can drive the film material roller 631 to move up and down.

[0072] The pre-lamination mechanism 61 includes a pre-lamination suction plate 611, a pre-lamination mounting frame 612, and a set of fourth cylinders 613. The fourth cylinders 613 are fixed to the pre-lamination mounting frames 612. The pre-lamination suction plate 611 is rotatably mounted within the pre-lamination mounting frames 612. The power output of the fourth cylinders 613 is connected to the pre-lamination suction plate 611 to drive the pre-lamination suction plate 611 downward relative to the pre-lamination mounting frame 612, which is fixed within the machine base frame 66. Specifically, after the substrate 9 is precisely positioned and fixed by vacuum adsorption by the film pressing mechanism 5, the film material roller 631 rotates to unwind the film material (the film material includes three parts: PET release film, photosensitive layer, and PE film) and separate the release film and PE film after passing through the unwinding film group 62. The PE film is separated and then conveyed to the pre-laminating mechanism 61 after passing through the tensioning roller group 64 and extended to the negative pressure guide wheel 65. The PE film is sucked tightly by the adsorption effect of the negative pressure guide wheel 65 so that the PE film is close to the pre-laminating adsorption plate 611 and is sucked by the adsorption effect. At the same time, the fourth cylinder 613 starts to drive the pre-laminating adsorption plate 611 to rotate and close to the upper surface of the substrate 9 on the film laminating platform 513. At this time, the film laminating platform 513 will drive the PE film to pass through the heating pressure roller 67 and the back pressure wheel in sequence during the process of resetting along the conveying mechanism 1. The pressing assembly 68 is heated by the heated pressure roller 67 and the backup back pressure wheel pressing assembly 68 is pressed tightly against the surface of the substrate 9. When the substrate 9 and the film pasting platform 513 have completely passed through the back pressure wheel pressing assembly 68, the PE film is cut by a cutter to complete the film pasting of a piece of substrate 9. Such a cycle can realize continuous film pasting. The separated release film is transferred to the waste collection roller 632 located above the film material roller 631. The waste collection roller 632 is driven by its own gravity to rotate the film material roller 631 while driving the waste collection roller 632 to rotate in the opposite direction (because the surface of the film material is in contact with the release film after being peeled off, there is friction between the two, so when the film material rotates with the film material roller 631, it will drive the release film after being peeled off to wrap around the waste collection roller 632 in the opposite direction) to collect the release film.

[0073] During operation, the substrate 9 is first placed on the initial positioning mechanism 4 via the first feeding mechanism 2 or the second feeding mechanism 3. The first lifting and receiving mechanism 43 of the initial positioning mechanism 4 rises, receiving the substrate 9. Then, the first cylinder 441 of the positioning assembly 44 drives the drive frame 442 to move, and the substrate 9 is initially positioned via the limit rod 443. After positioning is completed, the clamping mechanism 24 of the first feeding mechanism 2 or the clamping mechanism 24 of the second feeding mechanism 3 drives the clamping claw 243 via the third cylinder 242 to clamp the substrate 9. Then, with the cooperation of the third drive module 21 and the fourth drive module 22, the substrate 9 is transferred from the initial positioning mechanism 4 to the film pressing mechanism 5.

[0074] The vacuum adsorption mechanism 51 of the lamination mechanism 5 receives the substrate 9 via the second lifting and receiving mechanism 520. The negative pressure stage 514 then generates negative pressure, adsorbing the substrate 9 onto the lamination platform 513. The deviation correction and clamping mechanism 52 adjusts the position of the substrate 9 via the first and second drive mechanisms 533 and 534, ensuring accurate positioning of the substrate 9.

[0075] The pre-lamination mechanism 61 of the film laminating mechanism 6 uses a fourth air cylinder 613 to drive the pre-lamination suction plate 611 downward relative to the pre-lamination mounting frame 612, pre-attaching the film material to one side of the upper surface of the substrate 9 (the side of the substrate 9 near the heated pressure roller 67). The unwinding film assembly 62 provides the film material, the tensioning roller assembly 64 maintains the film material's tension, the negative pressure guide wheel 65 guides the film material to accurately adhere to the substrate 9, and the heated pressure roller 67 heats and presses the adhered film material to ensure film lamination quality. The waste film collection assembly 63 collects the discarded film material.

[0076] After the film is pasted, the clamping mechanism 24 of the second feeding mechanism 3 drives the clamping claw 243 through the third cylinder 242 to clamp the film-pasted substrate 9, and then, with the cooperation of the third driving module 21 and the fourth driving module 22, transfers the substrate 9 from the film pressing mechanism 5 to the initial positioning mechanism 4 or the next process.

[0077] This single-sided film laminating machine for substrate 9 realizes the automated single-sided film laminating process of substrate 9 through the coordinated work of the conveying mechanism 1, the feeding mechanism, the initial positioning mechanism 4, the film pressing mechanism 5 and the film laminating mechanism 6, improves the accuracy and efficiency of the film laminating, and reduces the errors and instability caused by manual operation.

[0078] The single-sided film laminating machine for substrate 9 in this embodiment realizes precise positioning and efficient film laminating of substrate 9 through the coordinated work of the initial positioning mechanism 4, the film pressing mechanism 5 and the film laminating mechanism 6, thereby improving the accuracy and efficiency of film laminating. Compared with the prior art, this technology adopts the setting of loading and unloading on the same side, so that the first feeding mechanism 2 can be used for loading and unloading, and the second feeding mechanism 3 can be used for unloading and loading, and can even be used crosswise or alone according to the loading situation, which greatly improves the flexibility and adaptability of the equipment. In addition, the edge positions on both sides of the substrate 9 are grasped by the visual positioning system 8 to adjust the angle and accuracy, and combined with vacuum adsorption fixation, the accuracy of film laminating of substrate 9 is ensured. The special design of the limit rod 443 reduces the friction between the edge of substrate 9 and the sleeve 444, effectively avoiding damage to substrate 9. The design of the film laminating mechanism 6 realizes continuous film laminating operation and improves production efficiency, thereby overcoming the problems of inaccurate positioning, low film laminating efficiency, and complex operation in the process of laminating substrate 9 in the prior art.
