Description

Technical Field

[0001] This invention relates to the technical field of laminating machines, specifically a vacuum laminating machine for film materials that works in conjunction with roller pressing for debubbling. Background Technology

[0002] The manufacturing of optical components plays a crucial role in the performance of various electronic products and precision equipment. Among the many processes in producing optical components, the precise lamination of the film material onto the substrate is particularly critical. Specifically, this process is typically accomplished using pressure rollers. The rollers continuously roll over the film material, applying pressure to ensure a tight bond between the film and the substrate. Crucially, the entire lamination process is conducted in a vacuum environment, which effectively removes any air bubbles or other air gaps that may be present between the substrate and the film, creating ideal conditions for a tight bond.

[0003] Typically, the axial direction of the pressure roller is aligned with the width direction of both the substrate and the film. When the pressure roller operates in this configuration, air and air bubbles are primarily expelled along the roller's running direction. This can lead to localized air accumulation between the film and the substrate (i.e., air and air bubbles in the middle section are difficult to expel quickly from the film edges, resulting in localized accumulation in the middle). Once this localized accumulation occurs, it has a severely detrimental effect on the bonding quality between the film and the substrate. Specifically, it manifests as weak bonding and may even result in noticeable air bubbles.

[0004] These defects not only severely affect the appearance of the final product, making it fail to meet the requirements of high-quality products, but also significantly impact product performance, reducing the optical performance and lifespan of optical components. They also necessitate re-lamination of defective products or the direct discarding of irreparable defective items. Both re-lamination and product discarding directly increase material waste. While increasing the number of roller passes may improve localized buildup issues, increasing the number of passes directly extends the production time of individual products, reducing overall production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a vacuum laminating machine for film materials that is compatible with roller pressing for degassing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vacuum laminating machine for film materials that cooperates with roller pressing for debubbling includes a cabinet and a support platform disposed within the cabinet, and further includes:

[0008] The movable enclosure is located inside the cabinet, above the support platform, and can descend from inside the cabinet onto the support platform to form a sealed chamber with the support platform;

[0009] The transverse frame is movable inside the cover. The transverse frame can be driven by two sets of threaded drive mechanisms on the cover to move along the length of the cover. The transverse frame is also movable with an assembly frame.

[0010] The two pressure rollers are located in the assembly frame. The two pressure rollers have the same structure and are each connected to a set of form switching mechanisms. The form switching mechanisms can switch between the concentric docking state and the misaligned tilting state of the two pressure rollers.

[0011] The threaded drive mechanism drives two pressure rollers to move back and forth along the length of the support platform, so that the two pressure rollers perform a first roll and a second roll on the film material in sequence. During the first roll, the two pressure rollers are in a concentric docking state, and during the second roll, the two pressure rollers are in a staggered and tilted state.

[0012] As a further aspect of the present invention: the support platform is provided with a placement area for supporting the substrate and the film material, and the bottom of the support platform is also provided with a plurality of first suction nozzles located in the placement area;

[0013] The support platform is also provided with a sealing groove that surrounds the placement area. The sealing groove is adapted to the cover. The side of the cover is provided with multiple second suction nozzles. Both the first suction nozzle and the second suction nozzle are connected to a negative pressure pump. A first cylinder is also fixed inside the cabinet. The movable end of the first cylinder is fixed to the cover.

[0014] As a further embodiment of the present invention: a plurality of second cylinders are fixedly installed on the transverse frame, and the movable end of the second cylinder is fixed to the assembly frame. When the sealed chamber is formed, the second cylinder can drive the assembly frame to move toward the film material so that the pressure roller applies pressure to the film material. After the first rolling is completed, before the second rolling begins, the pressure provided by the second cylinder to the pressure roller increases.

[0015] As a further embodiment of the present invention: the form switching mechanism is provided with a sliding component on the assembly frame and a driven component connected to the sliding component. The sliding component can drive the driven component to move along the width direction of the assembly frame so that the two pressure rollers are misaligned. The driven component can cause the pressure rollers to perform a swaying action.

[0016] As a further embodiment of the present invention: the sliding assembly includes an assembly plate slidably connected to the assembly frame, the assembly plate being slidable along the width direction of the assembly frame, and a third cylinder being fixedly installed on the side of the assembly frame, the movable end of the third cylinder being fixed to the assembly plate;

[0017] The driven component is located on the assembly plate and is movable along the length of the assembly plate.

[0018] As a further embodiment of the present invention: the assembly plate is provided with a guide groove, the driven component includes a movable seat that is slidably fitted in the guide groove, two sets of elastic components are connected between the movable seat and the assembly plate, and a sliding fit structure is also provided between the movable seat and the assembly frame;

[0019] The movable seat has a swing arm rotatably mounted on its lower part, and the pressure roller is rotatably mounted on the swing arm. A second motor is also mounted on the movable seat. The output end of the second motor is connected to the rotation shaft of the swing arm, which drives the swing arm to tilt the pressure roller.

[0020] As a further embodiment of the present invention: the elastic component includes a protruding block fixed to the side of the assembly plate, a crossbar fixed to the protruding block, and a cylindrical spring sleeved on the outer periphery of the crossbar. The movable seat is fixedly connected to a follower block, the follower block is slidably connected to the crossbar, and the two ends of the cylindrical spring are respectively connected to the protruding block and the follower block.

[0021] As a further embodiment of the present invention: the sliding fit structure includes a column fixedly disposed on the movable seat and a guide plate fixedly disposed on the assembly frame, wherein the guide plate is provided with a through groove that mates with the column.

[0022] As a further embodiment of the present invention: the through groove includes a first side and a second side, each having two segments. The two segments of the first side form a "V" shape, and one segment of the two segments of the second side is a straight segment, while the other end is an inclined segment parallel to the first side. The distance between the two segments is equal to the diameter of the column.

[0023] As a further embodiment of the present invention: the threaded drive mechanism includes a lead screw rotatably mounted inside the cover and a first motor mounted on the outer wall of the cover, the output end of the first motor being connected to the lead screw, and the lead screw passing through the transverse frame and being threadedly connected to the transverse frame.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This invention uses two identical pressure rollers to perform a first and second rolling process during bonding. During the first rolling, the two pressure rollers are concentrically connected to form a roller structure with an axial length greater than the width of the film. This roller structure is used to perform preliminary bonding and stabilization treatment on the film. Before the second rolling, the two pressure rollers switch from a concentric connection to a staggered tilted state.

[0026] During the secondary rolling process, increasing the pressure and utilizing the tilt angle of the pressure rollers helps to push air bubbles towards the edge and expel them, which can effectively improve the problem of local accumulation, improve the bonding firmness, and ensure the appearance and performance of the final product. Moreover, it does not require increasing the number of rolling cycles, thus improving the production efficiency.

[0027] Furthermore, by setting up a cover, before the roll bonding, the cover moves downward to form a sealed chamber with the support platform. The second suction nozzle is used to evacuate this sealed chamber, thereby improving the efficiency of air and bubble removal during the bonding process. Compared to creating a larger vacuum space, the sealed chamber formed by the cover and the support platform can more efficiently evacuate the vacuum and more thoroughly remove air and bubbles between the film and the substrate, significantly improving the degassing effect, reducing bubble residue, and improving the bonding quality.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0041] Please see Figures 1-10 In this embodiment of the invention, a vacuum laminating machine for film material debubbling in conjunction with roller pressing includes a cabinet 1 and a support platform 2 disposed within the cabinet 1, and further includes:

[0042] The cover 3 is located inside the cabinet 1. The cover 3 is above the support platform 2 and can be lowered from inside the cabinet 1 onto the support platform 2 to form a sealed chamber with the support platform 2.

[0043] The transverse frame 9 is movable inside the cover 3. The transverse frame 9 can be driven by two sets of threaded drive mechanisms on the cover 3 to move along the length direction of the cover 3. The transverse frame 9 is also movably provided with an assembly frame 11.

[0044] The two pressure rollers 16 are set in the assembly frame 11. The two pressure rollers 16 have the same structure and are respectively connected to a set of form switching mechanism. The form switching mechanism can switch the two pressure rollers 16 from the concentric docking state to the misaligned tilting state.

[0045] The threaded drive mechanism drives the two pressure rollers 16 to move back and forth along the length of the support platform 2, so that the two pressure rollers 16 perform a first roll and a second roll on the film material in sequence. During the first roll, the two pressure rollers 16 are in a concentric docking state, and during the second roll, the two pressure rollers 16 are in a staggered and tilted state.

[0046] Please see Figure 10 For a single roll pressing, the ends of the two pressure rollers 16 are joined together and concentric. Therefore, the two pressure rollers 16 can form a roller structure with an axial length greater than the width of the film. Using this roller structure, during a single roll pressing, the two pressure rollers 16 roll along the length of the film with a smaller pressure, which plays a role in the initial bonding and stabilization of the film.

[0047] After the first rolling is completed and before the second rolling begins, the shape switching mechanism will work to drive the two pressure rollers 16 to be misaligned and to swing in opposite directions, forming a misaligned and tilted distribution. During the second rolling, the tilted shape of the pressure rollers 16 will make it easier for air and bubbles between the film and the substrate to be discharged at the edge of the film.

[0048] Therefore, this invention uses two identical pressure rollers 16 to perform a first and second rolling process during bonding. During the first rolling, the two pressure rollers 16 are concentrically aligned, forming a roller structure with an axial length greater than the width of the film. This roller structure is used to perform preliminary bonding and stabilization treatment on the film. Before the second rolling, the two pressure rollers 16 switch from a concentric alignment to a staggered tilted state. Therefore, during the second rolling, the pressure is increased, and the tilt angle of the pressure rollers 16 helps to push air bubbles towards the edge and expel them, effectively improving the problem of local accumulation, enhancing the bonding firmness, ensuring the appearance and performance of the final product, and improving production efficiency without having to increase the number of rolling cycles.

[0049] Please refer to it again. Figure 3 , Figure 4 as well as Figure 5 The support platform 2 is provided with a placement area 201 for supporting the substrate and the film material, and the bottom of the support platform 2 is also provided with a plurality of first suction nozzles 5 located in the placement area 201; wherein, the support platform 2 is also provided with a sealing groove 202 surrounding the placement area 201, the sealing groove 202 is adapted to the cover 3, the side of the cover 3 is provided with a plurality of second suction nozzles 6, and the first suction nozzles 5 and the second suction nozzles 6 are all connected to a negative pressure pump, and a first cylinder 4 is also fixed inside the cabinet 1, the movable end of the first cylinder 4 being fixed to the cover 3.

[0050] Furthermore, during the actual bonding process, the substrate and film material can be transferred to the placement area 201 on the support platform 2 using a negative pressure suction cup. Multiple first suction nozzles 5 are used to adsorb the substrate, fixing it on the support platform 2 and ensuring the stability of the substrate during subsequent bonding. Subsequently, the first cylinder 4 drives the cover 3 to move down until the bottom end of the cover 3 enters the sealing groove 202, thereby forming a sealed chamber between the cover 3 and the support platform 2.

[0051] Once a sealed chamber is formed, the second suction nozzle 6 begins to evacuate the sealed chamber, making it approach a vacuum state, which facilitates the removal of air bubbles between the substrate and the film during the bonding process.

[0052] This invention, by setting up a cover 3, allows the cover 3 to move downwards before roller pressing and bonding, forming a sealed chamber between the cover 3 and the support platform 2. The second suction nozzle 6 is used to evacuate this sealed chamber, thereby improving the efficiency of air and bubble removal during the bonding process. Compared to creating a larger vacuum space (i.e., inside the bonding processing cabinet), this invention, by utilizing the sealed chamber formed by the cover 3 and the support platform 2, can more efficiently evacuate the vacuum and more thoroughly remove air and bubbles between the film material and the substrate, significantly improving the degassing effect, reducing bubble residue, and improving bonding quality.

[0053] Secondly, after the bonding work is completed, the first cylinder 4 drives the cover 3 to move upward and reset, and the cover 3 separates from the support platform 2, which can quickly restore the normal pressure environment, improve work efficiency, and the bonding is carried out in the sealed chamber, which can effectively reduce the entry of external dust and pollutants and improve the bonding quality.

[0054] Please refer to it again. Figure 7 Multiple second cylinders 10 are fixedly installed on the transverse frame 9. The movable end of the second cylinder 10 is fixed to the assembly frame 11. After the sealed chamber is formed, the second cylinder 10 can drive the assembly frame 11 to move toward the film material so that the pressure roller 16 applies pressure to the film material. After the first rolling is completed, before the second rolling begins, the pressure provided by the second cylinder 10 to the pressure roller 16 increases.

[0055] Specifically, after the first cylinder 4 drives the cover 3 to move down, forming a sealed chamber between the cover 3 and the support platform 2, the pressure roller 16 does not contact the film material. Instead, the second cylinder 10 drives the assembly frame 11 to move the two pressure rollers 16 gradually towards the film material until the pressure rollers 16 apply the pressure required for one roll pressing. After the first roll pressing is completed and before the second roll pressing begins, the first cylinder 4 increases the pressure provided to the pressure rollers 16.

[0056] Please refer to it again. Figure 7 and Figure 9 The form-changing mechanism includes a sliding component on the assembly frame 11 and a driven component connected to the sliding component. The sliding component can drive the driven component to move along the width direction of the assembly frame 11, so that the two pressure rollers 16 are misaligned. The driven component can cause the pressure rollers 16 to perform a yaw action. The sliding component includes an assembly plate 12 slidably connected to the assembly frame 11. The assembly plate 12 can slide along the width direction of the assembly frame 11. A third cylinder 21 is fixedly installed on the side of the assembly frame 11, and the movable end of the third cylinder 21 is fixed to the assembly plate 12. The driven component is located on the assembly plate 12 and can move along the length direction of the assembly plate 12.

[0057] It should be noted that in the two sets of form switching mechanisms, the installation directions of the third cylinder 21 are opposite. That is, when it is necessary to switch the concentric docking state of the two pressure rollers 16 to the misaligned tilting state, the third cylinder 21 drives the assembly plate 12 to slide along the width direction of the assembly frame 11. Correspondingly, the movement directions of the two pressure rollers 16 are opposite, so as to achieve the misalignment of the two.

[0058] The assembly plate 12 is provided with a guide groove. The driven component includes a movable seat 13 that is slidably fitted in the guide groove. Two sets of elastic components are connected between the movable seat 13 and the assembly plate 12. A sliding fit structure is also provided between the movable seat 13 and the assembly frame 11. A swing arm 15 is rotatably mounted on the lower part of the movable seat 13. The pressure roller 16 is rotatably mounted on the swing arm 15. A second motor 14 is also mounted on the movable seat 13. The output end of the second motor 14 is connected to the rotation shaft of the swing arm 15 to drive the swing arm 15 to tilt the pressure roller 16.

[0059] Please refer to it again. Figure 6 The elastic component includes a protruding block 17 fixed to the side of the mounting plate 12, a crossbar 18 fixed to the protruding block 17, and a cylindrical spring 19 sleeved on the outer periphery of the crossbar 18. The movable seat 13 is fixedly connected to a follower block 1301, which is slidably connected to the crossbar 18. The two ends of the cylindrical spring 19 are respectively connected to the protruding block 17 and the follower block 1301.

[0060] With attachment Figure 7 Taking the state shown as an example, at this time, the two pressure rollers 16 are in a concentric docking state, and the column spring 19 is in a compressed state. Thus, the column spring 19 can provide elastic support force, so that the ends of the two pressure rollers 16 can be tightly docked, avoiding the problem of incomplete rolling due to gaps between the two pressure rollers 16 during one rolling process.

[0061] Please refer to it again. Figure 7 The sliding fit structure includes a column 1302 fixedly mounted on the movable seat 13 and a guide plate 20 fixedly mounted on the assembly frame 11. The guide plate 20 has a through groove that mates with the column 1302. The through groove includes a first side and a second side, each having two sections. The two sections of the first side form a "V" shape, and one section of the two sections of the second side is a straight section, while the other end is an inclined section parallel to the first side. The distance between the two sections is equal to the diameter of the column 1302.

[0062] With attachment Figure 7 Taking the state shown as an example, at this time, the column 1302 and the guide plate 20 are not in contact, and the column spring 19 can provide effective elastic support force, so that the ends of the two pressure rollers 16 are tightly attached.

[0063] When it is necessary to switch the concentric docking state of the two pressure rollers 16 to the staggered tilting state, the third cylinder 21 drives the assembly plate 12 to slide along the width direction of the assembly frame 11. Correspondingly, the column 1302 will contact the first side. Since the two sections of the first side are "V" shaped, the column 1302 will make way, so that the movable seat 13 and the assembly plate 12 slide relative to each other, and the two movable seats 13 in the assembly frame 11 move away from each other, and the ends of the two pressure rollers 16 separate.

[0064] Subsequently, the column 1302 enters between the first and second sides and repositions again. Specifically, the column 1302 slides with the guide plate 20, causing the two movable seats 13 within the assembly frame 11 to move closer to each other. Correspondingly, the pressure rollers 16 are displaced in the width direction of the film material, that is, the two pressure rollers 16 move closer to the middle of the film material by a certain distance. Therefore, since the projections of the two pressure rollers 16 overlap in the width direction, when the second motor 14 drives the swing arm 15 to tilt the pressure rollers 16, the projections of the two pressure rollers 16 in the width direction will not separate, thus ensuring that the rolling range of the two pressure rollers 16 can cover the width range of the film material during the secondary rolling process.

[0065] Please refer to it again. Figure 3 and Figure 4 The threaded drive mechanism includes a lead screw 8 rotatably installed inside the cover 3 and a first motor 7 installed on the outer wall of the cover 3. The output end of the first motor 7 is connected to the lead screw 8, and the lead screw 8 passes through the transverse frame 9 and is threadedly connected to the transverse frame 9.

[0066] In detail, the transverse frame 9 is provided with a threaded hole adapted to the lead screw 8. The lead screw 8 passes through the threaded hole and is threadedly connected to the transverse frame 9. During the first rolling, the first motor 7 drives the lead screw 8 to rotate in the forward direction, and the transverse frame 9 and the lead screw 8 are threadedly engaged. As a result, the transverse frame 9 can move along the length of the film material, so that the pressure roller 16 rolls the film material. During the second rolling, the first motor 7 drives the lead screw 8 to rotate in the reverse direction, so the transverse frame 9 can move in the reverse direction.

[0067] The movement of the pressure roller 16 is achieved through a threaded drive, which effectively improves the stability and uniformity of the rolling of the pressure roller 16, thereby ensuring the stable progress of the bonding process and the bonding effect.
