This multi-functional integrated fully automatic laminating machine, after completing the lamination and cutting of the upper and lower surfaces of the lens substrate, can simultaneously perform automated protective assembly of the workpiece's sides, eliminating the need for manual installation of side protection structures.

Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a multi-functional integrated fully automatic laminating machine. Background Technology

[0002] Laminating machines are packaging equipment used for wrapping and protecting the surface of objects. They are widely used in the production and processing of optical lenses and glass substrates to apply protective films to the surface of workpieces for dust and scratch protection. A typical laminating device mainly consists of a workpiece conveying mechanism, a film feeding mechanism, a laminating and pressing mechanism, and a film cutting mechanism. During operation, the conveying mechanism moves the workpiece to be processed, simultaneously feeding out the protective film. After being pressed by the pressing mechanism, the protective film is flatly adhered to the upper and lower surfaces of the workpiece. Then, the cutting mechanism removes excess film along the workpiece contour. The accompanying robotic arms for picking up and unloading can automatically pick up and place the workpiece for transfer. The entire system enables continuous laminating and packaging operations, significantly improving the processing efficiency and consistency of workpiece surface protection.

[0003] Existing lamination equipment generally focuses only on applying protective films to the top and bottom optical surfaces of workpieces, lacking automated protective structures for the workpiece sides. After lamination, the workpiece sides are completely exposed, with the cut edges of the protective film also directly exposed. During subsequent stacking, transfer, and processing, the exposed workpiece sides are susceptible to impacts, resulting in chipping and damage. The exposed protective film edges are easily scratched, causing lifting and detachment. Furthermore, dust and dirt easily accumulate on the sides, making cleaning difficult and directly weakening the overall protective effect of the lamination. Currently, side protection in the industry largely relies on manually applying protective tape or using flexible rings, resulting in low efficiency, poor protective consistency, and inability to synchronize with fully automated lamination production lines. This hinders the improvement of automation levels in the entire lens substrate lamination and packaging process, reducing the overall protective integrity of the workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-functional integrated fully automatic laminating machine to solve the problems mentioned in the background art. Existing laminating devices only apply protective films to the upper and lower surfaces of the workpiece without configuring an automated side protection structure. After lamination, the sides of the workpiece and the film-cut edges are exposed, which easily leads to problems such as edge chipping, film edge lifting and delamination, and difficult-to-clean dirt accumulation during the transfer process. The protective effect is limited. Currently, side protection mostly relies on manual operation, which is inefficient, inconsistent, and difficult to adapt to fully automatic laminating production lines, thus restricting the automation level and protective integrity of lens substrate laminating and packaging.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional integrated fully automatic laminating machine, comprising a laminating conveyor, a lens substrate conveyor disposed on one side of the laminating conveyor, and a laminating mechanism installed on the top of the laminating conveyor. A packaging material picking robot arm is fixed near the output end of the laminating conveyor, and a discharge robot arm is fixed outside the output end of the laminating conveyor. A finished product conveyor is disposed on one side of the output end of the laminating conveyor. Two placement boxes are symmetrically arranged on both sides of the top of the laminating conveyor between the laminating mechanism and the discharge robot arm. A storage slot is opened through the interior of each of the two placement boxes. Several aluminum alloy snap-fit ​​edge strips are stacked inside the storage slots. A sidewall packaging component is disposed at the bottom of each of the two placement boxes. An edge pressing component is disposed on both sides of the bottom between the two placement boxes.

[0006] Furthermore, a number of carrying trays are placed at the top of the lens substrate conveyor, a tray placement rack is fixed at the output end of the lens substrate conveyor, a number of packaging boxes are placed at the top of the finished product conveyor, a control box is fixedly installed on one side of the laminating conveyor, and a film cutting mechanism is installed on the side of the laminating conveyor near the laminating mechanism.

[0007] Furthermore, the sidewall packaging assembly includes a limiting tray and a first cylinder. The limiting tray is disposed at the bottom of the placement box, and the first cylinder is fixedly installed on the outer side wall of the limiting tray away from the opening. A mounting frame is fixedly installed at the bottom of the limiting tray, and the bottom of the mounting frame is fixedly installed on the top outside of the film-coating conveyor.

[0008] Furthermore, a first suction cup frame is fixedly installed at the output end of the first cylinder located inside the limiting tray, and a baffle is fixedly installed at the top of the first suction cup frame. The lowest aluminum alloy snap-fit ​​strip in the storage slot of the placement box is horizontally placed inside the limiting tray.

[0009] Furthermore, the aluminum alloy snap-fit ​​edge strip is C-shaped, and a snap-fit ​​groove is provided around the inside of the aluminum alloy snap-fit ​​edge strip, with rubber strips embedded and fixed at the edges of the snap-fit ​​groove.

[0010] Furthermore, a fixing frame is fixedly installed between the two placement boxes, and a second cylinder is fixedly installed at the top center of the fixing frame, and a second suction cup frame is fixedly installed at the bottom of the output end of the second cylinder.

[0011] Furthermore, the pressing assembly includes a fixed plate and two rotating frames. The two ends of the fixed plate are fixedly installed on the outside of the bottom of the two placement boxes. The two rotating frames are symmetrically arranged on the outside of the top and bottom of the fixed plate. Rotating seats are rotatably installed on the outside of both ends of the two rotating frames.

[0012] Furthermore, one end of the rotating seat is fixedly installed on the outside of the fixed plate, a double-sided rack is provided between one end of the two rotating frames, and a limit gear is fixedly fitted on the outside of the two rotating frames near the double-sided rack, and the limit gear meshes with the double-sided rack.

[0013] Furthermore, a limiting rod is slidably installed through the middle of the double-sided rack. One end of the limiting rod is fixedly installed on the outside of one side of the fixed plate, and a limiting block is fixedly installed on the other end of the limiting rod. A rotating shaft is rotatably engaged at the ends of the two rotating frames away from the fixed plate. A squeezing roller is sleeved and fixed on the outside of the rotating shaft. A double-headed cylinder is horizontally fixed on the outside of the bottom end of one of the placement boxes.

[0014] Furthermore, connecting rods are fixedly installed on both output ends of the double-headed cylinder. Several sliding blocks are slidably connected to the outside of the connecting rods at equal intervals. One end of each sliding block is fixedly installed on the outside of the placement box. The end of the connecting rod away from the double-headed cylinder is fixedly connected to one side of the double-sided rack.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up the placement box and side wall packaging components, this multi-functional integrated fully automatic laminating machine can simultaneously carry out automated protective assembly of the workpiece side after completing the lamination and cutting of the upper and lower surfaces of the lens substrate. There is no need for manual installation of the side protection structure, which effectively improves the work efficiency and protection consistency of the lamination and packaging process. Two sets of C-shaped aluminum alloy snap-fit ​​edge strips form a protective structure that completely wraps the side of the workpiece, which can resist the impact of external forces during circulation and stacking, prevent the side of the lens substrate from chipping, and cover the cut edge of the protective film to avoid the film edge from scratching, lifting and delamination. When the finished products are stacked, the protective cover forms a support gap between adjacent lens substrates, and the protective film will not directly stick and rub against each other, ensuring the stability of the lamination and packaging quality.

[0016] 2. With the addition of the edge pressing component, this multi-functional integrated fully automatic laminating machine can simultaneously perform edge pressing and limiting operations after the aluminum alloy snap-fit ​​edge strips are assembled and fitted. This further enhances the assembly firmness and packaging stability of the side protection. A double-headed cylinder serves as the single power source, driving a double-sided rack to slide smoothly along the limiting rod via a connecting rod. Combined with the meshing transmission of the limiting gears, it can synchronously drive the upper and lower rotating frames to open and close around the rotating seat. The transmission synchronization is high, and the structure is compact and simple, eliminating the need for additional drive components, reducing manufacturing costs and simplifying control logic. During the pressing operation, the extrusion rollers smoothly press the upper and lower wings of the aluminum alloy snap-fit ​​edge strips, driving the wings to tightly press the rubber strip against the edge area of ​​the protective film. This further compacts the film edge, improving the bonding firmness, and also forms a circumferential clamping limit on the lens substrate, preventing the workpiece from shaking or shifting inside the protective cover. The large-opening slot design prevents damage to the film edge during fitting, further improving the overall quality and operational reliability of the laminating packaging.

[0019] 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.

[0020] Example 1: Please refer to Figures 1-9 and Figure 14 A multi-functional integrated fully automatic laminating machine includes a laminating conveyor 1, a lens substrate conveyor 2 disposed on one side of the laminating conveyor 1, and a laminating mechanism 5 installed on the top of the laminating conveyor 1. A packaging material picking robot arm 4 is fixed near the output end of the laminating conveyor 1 near the output end of the lens substrate conveyor 2. A discharge robot arm 6 is fixed outside the output end of the laminating conveyor 1. A finished product conveyor 3 is disposed on one side of the output end of the laminating conveyor 1. Two placement boxes 7 are symmetrically arranged on both sides of the top of the laminating conveyor 1 between the laminating mechanism 5 and the discharge robot arm 6. A storage slot 17 is opened through the interior of each of the two placement boxes 7. Several aluminum alloy snap-fit ​​strips 16 are stacked inside the storage slots 17. A side wall packaging component is disposed at the bottom of each of the two placement boxes 7.

[0021] Several carrying trays 35 are placed at the top of the lens substrate conveyor 2. A tray placement rack 34 is fixed at the output end of the lens substrate conveyor 2. Several packaging boxes 8 are placed at the top of the finished product conveyor 3. A control box 10 is fixedly installed on one side of the laminating conveyor 1. A film cutting mechanism 9 is installed on the side of the laminating conveyor 1 near the laminating mechanism 5.

[0022] The sidewall packaging assembly includes a limiting tray 12 and a first cylinder 13. The limiting tray 12 is located at the bottom of the placement box 7. The first cylinder 13 is fixedly installed on the outer side wall of the limiting tray 12 away from the opening. A mounting frame 11 is fixedly installed at the bottom of the limiting tray 12. The bottom of the mounting frame 11 is fixedly installed on the top outside of the film-coating conveyor 1.

[0023] The first cylinder 13 is located inside the limiting tray 12. The output end is fixedly installed with a first suction cup frame 14. A baffle 15 is fixedly installed on the top of the first suction cup frame 14. The bottom aluminum alloy snap-fit ​​strip 16 in the storage slot 17 of the placement box 7 is horizontally placed inside the limiting tray 12.

[0024] The aluminum alloy snap-fit ​​edge strip 16 is C-shaped, and the interior of the aluminum alloy snap-fit ​​edge strip 16 is provided with a snap-fit ​​groove 21. Rubber strips 22 are embedded and fixed at the edges of the snap-fit ​​groove 21 to increase the clamping friction, buffer and protect, and prevent the film layer from being scratched.

[0025] A fixing frame 18 is fixedly installed between the two placement boxes 7. A second cylinder 19 is fixed at the top center of the fixing frame 18. A second suction cup frame 20 is fixedly installed at the bottom of the output end of the second cylinder 19.

[0026] In this embodiment, the entire machine is controlled by the control box 10 to coordinate the operation of each mechanism, realizing fully automated operation of lens substrate feeding, surface coating, side protection assembly, and finished product unloading. The specific working principle and operation process are as follows: Several support trays 35 are placed on the conveying surface of the lens substrate conveyor 2. The lens substrates to be processed are placed stably inside the support trays 35. The support trays 35 can support and limit the lens substrates to prevent them from shifting or sliding during the conveying process, thus preventing damage to the optical surfaces. The lens substrate conveyor 2 drives the support trays 35 forward at a constant speed. When the conveyor reaches the output position, the packaging and picking robot arm 4 accurately grabs the lens substrates on the support trays 35 and smoothly transfers them to the conveying surface of the laminating conveyor 1, completing the automated feeding process. The entire process does not require manual contact with the lenses, avoiding the risk of surface contamination and scratches caused by manual operation, while significantly improving feeding efficiency.

[0027] The coating conveyor 1 drives the lens substrate forward at a constant speed. When it reaches the coating mechanism 5, the coating mechanism 5 simultaneously delivers the upper and lower protective films. The internal pressing rollers flatten and press the protective films onto the upper and lower optical surfaces of the lens substrate, ensuring a tight and bubble-free adhesion, thus completing the basic surface protection. The coated lens substrate continues to move with the coating conveyor 1 to the cutting mechanism 9. The cutting mechanism 9 precisely cuts along the outer contour of the lens substrate, removing excess film edges and making the edge of the protective film flush with the edge of the lens substrate, thus completing the coating process on the upper and lower surfaces of the lens substrate.

[0028] The coated lens substrate continues to be conveyed forward by the coating conveyor 1. When it reaches the side protection assembly station between the two placement boxes 7, the coating conveyor 1 stops running, so that the lens substrate is accurately positioned in the center of the assembly station. At this time, the fixing frame 18 is set up between the two placement boxes 7, the second cylinder 19 is activated, and the output rod of the second cylinder 19 extends downward, driving the second suction cup frame 20 to descend smoothly. When the second suction cup frame 20 contacts the top surface of the lens substrate, it fixes the lens substrate by negative pressure adsorption. Then, the second cylinder 19 drives the second suction cup frame 20 to rise slightly, so that the lens substrate is removed from the conveying surface of the coating conveyor 1. After the lift, the two ends of the lens substrate are completely aligned with the opening height and center position of the two side limiting trays 12. This lifting action can not only avoid friction and scratching between the aluminum alloy engaging edge strip 16 and the conveying surface when pushing the aluminum alloy engaging edge strip 16, but also ensure that the engagement height of the lens substrate and the aluminum alloy engaging edge strip 16 is accurately matched, preventing damage to the lens edge and coating during the engagement process, and effectively improving assembly accuracy and yield.

[0029] Both placement boxes 7 have vertically through storage slots 17 inside. Several aluminum alloy snap-fit ​​edge strips 16 are vertically stacked in the storage slots 17. Under the action of gravity, the bottom aluminum alloy snap-fit ​​edge strip 16 in the storage slot 17 naturally falls into the limiting tray 12 at the bottom of the placement box 7. The limiting tray 12 supports and limits the aluminum alloy snap-fit ​​edge strip 16 laterally, ensuring the stability of the protective cover and preventing deflection or displacement during the pushing process.

[0030] Once the lens substrate is lifted and positioned, the first cylinders 13 on both side limiting trays 12 are simultaneously activated. The output rods of the first cylinders 13 extend towards the lens substrate, pushing the first suction cup frame 14 horizontally forward along the inner cavity of the limiting tray 12. The first suction cup frame 14 uses negative pressure to adhere to the back end face of the corresponding aluminum alloy engaging edge strip 16, driving the aluminum alloy engaging edge strip 16 smoothly towards the middle lens substrate, so that the slot 21 on the inner side of the aluminum alloy engaging edge strip 16 aligns with the side of the lens substrate and smoothly engages. The aluminum alloy engaging edge strips 16 on both sides advance synchronously in opposite directions, and finally the mating end faces of the two protective covers abut against each other, together forming a closed protective structure that wraps around the entire circumference of the lens substrate.

[0031] During the process of the first suction cup holder 14 pushing the aluminum alloy engaging edge strip 16 forward, the surface of the baffle 15 is perpendicular to the horizontal pushing direction of the aluminum alloy engaging edge strip 16, the height of the top surface of the baffle 15 is flush with the lower edge of the bottom opening of the storage slot 17, and the extension length of the baffle 15 along the pushing direction is sufficient to completely cover the bottom opening area of ​​the storage slot 17. In the initial state, the first suction cup frame 14 retracts inside the limiting tray 12, and the baffle 15 avoids the side of the bottom opening of the storage slot 17. The aluminum alloy snap-fit ​​edge strips 16 stacked in the storage slot 17 can fall naturally under the action of gravity to replenish the material. As the first suction cup frame 14 adsorbs the bottom aluminum alloy snap-fit ​​edge strip 16 and moves forward, the baffle 15 moves horizontally to directly below the bottom opening of the storage slot 17, and supports the bottom end face of the remaining aluminum alloy snap-fit ​​edge strips 16 stacked above with its own top surface, completely blocking the falling channel of the storage slot 17, preventing the aluminum alloy snap-fit ​​edge strips 16 above from falling under the action of gravity, and ensuring the continuous and stable assembly process.

[0032] Meanwhile, the aluminum alloy material has high structural strength, which can effectively resist the impact of external forces during subsequent stacking and transportation, effectively avoid the problem of chipping or damage on the side of the lens substrate, and can also completely cover the cut edge of the protective film, preventing the film edge from being scratched by external forces and causing it to peel or detach. It also prevents dust and dirt from accumulating directly on the side area, thus improving the overall effect of the coating protection.

[0033] After the side protection assembly is completed, the first suction cup frame 14 releases its adsorption on the aluminum alloy engaging edge strip 16, and the first cylinder 13 drives the first suction cup frame 14 to retract and reset, returning to its initial position within the limiting tray 12. When the first suction cup frame 14 drives the baffle 15 to retract to the side of the bottom opening of the storage slot 17, the blocking and limiting effect of the baffle 15 is released, and the stacked aluminum alloy engaging edge strips 16 in the storage slot 17 automatically fall under the action of gravity. The bottom aluminum alloy engaging edge strip 16 falls into the limiting tray 12, completing the material replenishment for the next assembly. This eliminates the need for frequent manual material replenishment, supports long-term continuous production of the equipment, and effectively improves overall operating efficiency.

[0034] After the protective cover material is replenished, the second cylinder 19 drives the second suction cup frame 20 downward again, smoothly placing the lens substrate with completed side protection back onto the conveying surface of the laminating conveyor 1. Subsequently, the second suction cup frame 20 releases the negative pressure adsorption and returns to its original position as it moves upward with the second cylinder 19. The laminating conveyor 1 restarts, driving the finished lens substrate to continue moving towards the output end. Upon reaching the output end, the unloading robotic arm 6 precisely grabs the finished lens substrate and transfers it into the packaging box 8 on the finished product conveyor 3, where it is stacked in an orderly manner.

[0035] Because the lens substrates are surrounded by aluminum alloy snap-fit ​​strips 16, adjacent lens substrates are supported and contacted by the upper and lower ends of the aluminum alloy snap-fit ​​strips 16 during stacking. The protective films on the surface of the lens substrates do not directly adhere to each other, leaving sufficient gaps. This avoids problems such as film peeling and residual adhesive damage caused by mutual adhesion, and also reduces the risk of scratches caused by mutual friction between film surfaces, ensuring the consistent quality of the laminated packaging. When the finished products in the packaging box 8 are stacked to a specified quantity, the finished product conveyor 3 drives the packaging box 8 forward to discharge the material, completing the entire lamination and packaging process. The empty carrying trays 35 are collected at the tray placement rack 34 at the output end of the lens substrate conveyor 2, which can be recycled and reused, reducing production material costs.

[0036] The machine integrates the coating of the upper and lower surfaces of the lens substrate, the automated side protection assembly, and the orderly discharge of finished products into one unit. The entire process is automated and continuous, without the need for manual intervention for side protection operations. This effectively improves production efficiency and protection consistency, and can adapt to the needs of batch continuous production. It enhances the level of automation, improves the integrity of protection, and solves the industry pain point that existing equipment can only complete the coating of the upper and lower surfaces and side protection relies on manual operation.

[0037] Example 2: Please refer to Figures 10-13 This embodiment further illustrates Example 1, wherein pressing assemblies are provided on both sides of the bottom between the two placement boxes 7.

[0038] The pressing assembly includes a fixed plate 23 and two rotating frames 24. The two ends of the fixed plate 23 are fixedly installed on the outside of the bottom of the two placement boxes 7. The two rotating frames 24 are symmetrically arranged on the outside of the top and bottom of the fixed plate 23. Rotating seats 25 are rotatably installed on the outside of both ends of the two rotating frames 24.

[0039] One end of the rotating seat 25 is fixedly installed on the outside of the fixed plate 23. A double-sided rack 27 is provided between one end of the two rotating frames 24. A limit gear 26 is fixedly fitted on the outside of the two rotating frames 24 near the double-sided rack 27. The limit gear 26 meshes with the double-sided rack 27.

[0040] A limit rod 28 is slidably installed through the middle of the double-sided rack 27. One end of the limit rod 28 is fixedly installed on the outside of one side of the fixed plate 23, and the other end of the limit rod 28 is fixedly installed with a limit stop. The ends of the two rotating frames 24 away from the fixed plate 23 are rotatably engaged with a rotating shaft 32. A squeeze roller 33 is sleeved and fixed on the outside of the rotating shaft 32. A double-headed cylinder 29 is horizontally fixed on the outside of the bottom of one of the placement boxes 7.

[0041] Both output ends of the double-headed cylinder 29 are fixedly installed with connecting rods 30. Several sliding blocks 31 are slidably connected to the outside of the connecting rods 30 at equal intervals. One end of each sliding block 31 is fixedly installed on the outside of the placement box 7. The end of the connecting rod 30 away from the double-headed cylinder 29 is fixedly connected to one side of the double-sided rack 27.

[0042] In this embodiment, the edge pressing assembly works in conjunction with the side wall packaging assembly. After the aluminum alloy snap-fit ​​edge strips 16 are snapped together, they press and limit the upper and lower wings of the protective cover, ensuring that the protective cover is firmly snapped together and does not come loose, while also preventing damage to the film layer during the snap-fit ​​process. This further improves the assembly quality and stability of the side protection. The specific working principle and operation process are as follows: In the initial state, the output rods on both sides of the double-headed cylinder 29 are in a retracted state, which drives the connecting rod 30 and the double-sided rack 27 to the initial position close to the double-headed cylinder 29. At this time, the upper and lower limit gears 26 drive the corresponding rotating frame 24 to be in an open state, and the two sets of extrusion rollers 33 are separated from each other, leaving sufficient working space. This will not interfere with the pushing action of the aluminum alloy locking strip 16 and the lifting and positioning of the lens substrate, ensuring that the assembly action of the side wall packaging component is carried out smoothly.

[0043] During the process of the first cylinders 13 on both sides pushing the aluminum alloy engaging strip 16 towards the lens substrate for engagement, the initial opening distance of the slot 21 on the inner side of the aluminum alloy engaging strip 16 is greater than the total thickness of the upper and lower protective films superimposed on the lens substrate. Sufficient clearance is left between the upper and lower inner walls of the slot 21 and the surface of the protective film. Therefore, during the entire process of pushing and engaging the aluminum alloy engaging strip 16, the edge of the aluminum alloy engaging strip 16 will not scratch or lift the cut edge of the protective film. This avoids the problems of film edge lifting, delamination, and scratches during the assembly process from the structural source, ensuring the integrity of the coating layer.

[0044] Once the mating surfaces of the aluminum alloy snap-fit ​​strips 16 on both sides are fully contacted and enclosed to form a complete circumferential side protection structure, the double-headed cylinder 29 is activated. The output rods on both sides extend outwards simultaneously, driving the two connecting rods 30 to slide smoothly outwards along the guide of the slide block 31. Several slide blocks 31 are fixed at equal intervals on the outer wall of the placement box 7, providing multi-point support and guidance for the connecting rods 30, ensuring that the connecting rods 30 travel horizontally in a straight line without tilting or swaying, thus guaranteeing transmission accuracy and operational stability.

[0045] During the movement of the connecting rod 30, the double-sided rack 27 connected to its end slides outward synchronously along the axial direction of the limiting rod 28. The limiting rod 28 passes through the middle of the double-sided rack 27, which precisely limits the movement trajectory of the double-sided rack 27, further ensuring the smooth operation of the rack and avoiding misalignment or jamming during meshing. The limiting block at the end of the limiting rod 28 can limit the maximum extension stroke of the double-sided rack 27, preventing the rack from overtraveling and disengaging, and ensuring the safe operation of the transmission mechanism.

[0046] When the double-sided rack 27 slides outward, its upper and lower tooth surfaces mesh with the corresponding limiting gears 26, driving the two limiting gears 26 to rotate synchronously. Since the limiting gears 26 are fixedly sleeved on the ends of the rotating frame 24, the two rotating frames 24 rotate synchronously with the corresponding limiting gears 26, and converge towards each other around the support axis of the rotating seat 25. The rotating seat 25 is fixed to the surface of the fixed plate 23, providing stable rotational support for the rotating frame 24.

[0047] As the upper and lower rotating frames 24 close, the pressing rollers 33 mounted on the ends of the rotating frames 24 via the rotating shaft 32 synchronously move towards the upper and lower outer wings of the aluminum alloy engaging edge strip 16. Finally, the roller surfaces are smoothly pressed against the outer surfaces of the upper and lower wings of the aluminum alloy engaging edge strip 16, applying a uniform inward pressing force to the wings. Under pressure, the upper and lower wings of the aluminum alloy engaging edge strip 16 undergo elastic deformation inward along the root of the groove 21, causing the rubber strip 22 embedded and fixed in the inner wall of the groove 21 to be tightly pressed against the non-optical area of ​​the edge of the upper and lower protective films of the lens substrate.

[0048] This pressing action can further compact the edge area of ​​the protective film, improve the adhesion between the film edge and the lens substrate, and avoid problems such as lifting and delamination caused by external force during subsequent transportation and stacking. On the other hand, the symmetrical clamping pressure at the top and bottom creates a stable static friction force between the rubber strip 22, the lens substrate, and the protective film, forming a circumferential limit and fixation on the lens substrate. This ensures that the lens substrate will not shake or shift inside the aluminum alloy locking strip 16, eliminating the risk of the lens moving and bumping inside the cover during subsequent transportation and stacking, and greatly improving the stability and reliability of the packaging protection.

[0049] After the edge pressing operation is completed, the double-headed cylinder 29 drives the output rods on both sides to retract synchronously, pulling the connecting rod 30 to slide in the opposite direction along the slide block 31, which in turn drives the double-sided rack 27 to retract to the initial position along the limit rod 28. Through tooth surface meshing transmission, the limit gear 26 drives the rotating frame 24 to rotate synchronously in the opposite direction. The upper and lower rotating frames 24 open in opposite directions, causing the pressing roller 33 to disengage from the surface of the aluminum alloy engaging edge strip 16 and return to the initial open state. This completely avoids the lens conveying path and will not interfere with the subsequent lens lowering and conveying or the next round of protective cover pushing and assembly, ensuring the continuous and stable operation cycle.

[0050] After the edge pressing and reset is completed, the second cylinder 19 can drive the second suction cup frame 20 to move downward, and smoothly place the lens substrate with side protection and edge pressing fixed back onto the conveying surface of the laminating conveyor 1. Subsequently, the unloading robotic arm 6 grabs and transfers it into the packaging box 8 for stacking and storage, completing the entire laminating and packaging process.

[0051] In this embodiment, the pressing assembly uses a single double-headed cylinder 29 as the power source. Through the meshing transmission of the double-sided rack 27 and the limiting gear 26, it synchronously drives the upper and lower rotating frames 24 and the pressing rollers 33 to open and close. The transmission synchronization is high, the structure is compact and simple, and there is no need to set up multiple sets of driving components, which reduces the equipment manufacturing cost, simplifies the control logic, and ensures stable and reliable operation. At the same time, the pressing force and stroke can be adjusted by the cylinder parameters. Combined with the anti-film-scraping design of the large-opening slot 21, the entire mechanism achieves a firm locking and limiting of the aluminum alloy locking edge strip 16 and the lens substrate while ensuring that the assembly of the aluminum alloy locking edge strip 16 is free from film damage. This further improves the automated side protection function of the equipment and enhances the overall quality and consistency of the film-coated packaging.
