Description

Technical Field

[0001] This utility model relates to the technical field of backlight coating equipment, and in particular to a backlight coating equipment. Background Technology

[0002] Backlight coating (applying optical films such as diffusion / brightness enhancement films) is used to transform point or line LED light into a surface light source that is uniform, bright enough, has a suitable angle, lower energy consumption, and a more stable appearance.

[0003] During the backlight coating process, materials such as diffusion film and prism film need to be applied to the LED circuit board to coat the backlight. Although the coating process is carried out in a cleanroom, dust or particulate matter may be present during the placement or transportation of the backlight. If the coating is applied directly, the dust or particulate matter will affect the performance of the backlight in subsequent use.

[0004] Existing dust removal methods include electrostatic adsorption and air suction dust removal. Air suction dust removal involves installing coaxial suction pipes on both sides of the film-coated area and suctioning the film-coated area through coaxially arranged suction ports. However, the dust in the center cannot be effectively removed because the two suction ports are directly opposite each other and located on the same axis. This makes it inconvenient to use.

[0021] A second guide plate is disposed on the laminating platform and located on both sides of the laminating position with the first guide plate. The first dust collection component is located on the first guide plate, and the second dust collection component is located on the second guide plate. A second guide surface is formed at the end of the second guide plate away from the laminating platform, and a feeding channel is formed between the first guide surface and the second guide surface.

[0027] A robotic arm is placed on the side of the laminating table away from the laminating robotic arm, and is used to pick up the backlight from the conveyor belt and place it on the laminating position.

[0028] In at least one embodiment of this application, the backlight coating device further includes:

[0029] A picking robot is positioned on the laminating table and is used to place the backlight after lamination on the laminating position onto the conveyor belt. The picking robot and the placing robot are positioned opposite to each other.

[0030] The backlight coating device implementing this embodiment will have at least the following beneficial effects:

[0031] In the backlight coating equipment provided above, during operation, the conveyor belt transports the backlight to be coated to a position near the coating table and positions it at the coating position.

The two components superimpose on the coating position and the periphery to establish a unidirectional biased airflow from the side of the first dust collection component to the side of the second dust collection component. Thus, before the coating robot takes the coating material from the placement position and performs the coating, the dust located in the center and periphery of the coating position is guided along the conveying direction to the side of the second dust collection component and effectively removed.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] In one embodiment, a backlight coating apparatus 100 includes:

[0048] The laminating table 200 has a laminating position 210.

[0049] A coating robot 400 is located on one side of the coating position 210 and forms a placement position 430 for placing the coating material.

[0050] A conveyor belt 300 is disposed on the side of the laminating table 200 opposite to the laminating position 210, and is used to place a backlight.

[0051] The first dust collection component 500 is located on one side of the film covering platform 200.

[0052] The second vacuuming component 600 is disposed on the side of the laminating table 200 away from the first vacuuming component 500. In the transmission direction of the conveyor belt 300, the distance from the first vacuuming component 500 to the laminating table 200 is denoted as a, and the distance from the second vacuuming component 600 to the laminating table 200 is denoted as b, satisfying the relationship: a > b.

[0053] Please refer to Figures 1-4In this embodiment, with the transmission direction of the conveyor belt 300 as the reference direction, the distance from the first dust collection component 500 to the laminating table 200 is defined as a, and the distance from the second dust collection component 600 to the laminating table 200 is defined as b, and a>b is satisfied.

[0054] During operation, the conveyor belt 300 transports the backlight to be coated to a position near the coating stage 200 and then positions it at the coating position 210. The first dust collection component 500 and the second dust collection component 600 work simultaneously. Due to the asymmetric geometric relationship that a>b, the second dust collection component 600 generates a stronger negative pressure traction in the near field of the coating position 210 on the side closer to the coating stage 200, while the first dust collection component 500 forms a far-field guide on the side away from the coating stage 200. The two superimposed on the coating position 210 and the periphery establish a unidirectional biased airflow from the side of the first dust collection component 500 to the side of the second dust collection component 600. Thus, before the coating robot 400 picks up the coating material from the placement position 430 and performs the coating, the dust located at the center and periphery of the coating position 210 is guided along the transport direction to the side of the second dust collection component 600 and effectively removed.

[0055] By setting an asymmetrical positional relationship between the first dust collection component 500 and the second dust collection component 600 in the transmission direction, satisfying a>b, the backlight coating equipment 100 forms an offset airflow field with a clear direction of movement at the coating position 210, which significantly improves the movement and capture efficiency of dust in the center and near area of ​​the coating position 210, reduces secondary suspension and residue of dust, reduces optical defects such as bright spots, dark spots and pits caused by particles after coating, and improves the consistency and yield of the coated finished product.

[0056] In at least one embodiment of this application, the coating position 210 is located on the centerline of the conveyor belt 300 in the direction from the coating table 200 to the conveyor belt 300.

[0057] In at least one embodiment of this application, the distance from the first dust collection component 500 to the center line of the conveyor belt 300 is denoted as c, and the distance from the second dust collection component 600 to the center line of the conveyor belt 300 is denoted as d, satisfying the relationship: c > d.

[0058] Please refer to Figures 1-4 In this embodiment, the coating position 210 is set along the direction from the coating table 200 to the conveyor belt 300 so that the coating position 210 is precisely located on the center line of the conveyor belt 300.

[0059] Let c be the distance between the first vacuuming component 500 and the center line of the conveyor belt 300, and d be the distance between the second vacuuming component 600 and the center line of the conveyor belt 300. The two satisfy the asymmetric relationship that c>d.

[0060] The first suction component 500 is located on the side away from the centerline of the conveyor belt 300 and is mainly responsible for the far-field drainage function on the incoming side; the second suction component 600 is closer to the centerline of the conveyor belt 300 and is located in the near field of the film covering position 210 to enhance the near-field suction of the key area of ​​the film covering.

[0061] Combining the asymmetric distance relationship (a>b) in the transmission direction, a composite biased airflow is formed above and around the film-covered position 210, which points towards the side of the second dust collection component 600 in the transmission direction and converges towards the centerline side of the transmission belt 300 in the width direction.

[0062] By positioning the film-covering position 210 at the center line of the conveyor belt 300, the backlight's positioning posture is aligned with the film-covering path, reducing the impact of posture errors on airflow organization and cleaning effect.

[0063] By using a lateral offset of c>d, the airflow at the center of the covering film position 210 deviates from the centerline and tends to move towards the second dust collection component 600 in the width direction. Combined with the near-field suction of the second dust collection component 600, the fine dust in the center and near-field of the covering film position 210 is quickly drawn and removed before the film is applied, achieving efficient purification of the key area of ​​the film covering.

[0064] By positioning the laminating position 210 on the centerline of the conveyor belt 300, the backlight material receiving path, positioning, and laminating path are strictly coaxial, reducing airflow distortion and cleaning blind spots caused by eccentricity and track deviation.

[0065] The distance c from the centerline of the first dust collection component 500 to the centerline of the conveyor belt 300 is made greater than the distance d from the centerline of the second dust collection component 600 to the centerline of the conveyor belt 300 (c>d). An offset flow field is established in the width direction facing the centerline of the conveyor belt 300 and the side of the second dust collection component 600. This offset flow field is superimposed with the offset in the transmission direction (a>b) to form a directional and converging composite flow in the central area of ​​the coating position 210, which significantly improves the movement and capture efficiency of the central micro dust and suppresses secondary suspension and residue.

[0066] In at least one embodiment of this application, the first vacuuming assembly 500 includes:

[0067] The suction nozzle 510 has a suction port 511. The angle between the axis of the suction port 511 and the transmission surface 310 of the transmission belt 300 is denoted as e, which satisfies the relationship: 3 degrees ≤ e ≤ 10 degrees.

[0068] Please refer to Figures 1-4 In this embodiment, the angle between the axis of the suction port 511 and the transmission surface 310 of the conveyor belt 300 is defined as e. During assembly, an angle positioning fixture is used to ensure that e satisfies 3°≤e≤10°.

[0069] During operation, the backlight to be coated is transported to the coating position 210 by the conveyor belt 300 and positioned. Then, the suction nozzle 510 generates a synthetic airflow with both normal adsorption and tangential sweeping components in the vicinity of the conveyor surface 310 of the conveyor belt 300 at the aforementioned tilt angle.

[0070] The smaller normal component lifts the fine dust adhering to the substrate surface from the boundary layer, while the tangential component introduced by the tilt angle e guides the lifted dust to the opposite side along the transport surface 310 of the transport belt 300, thereby cooperating with the second dust collection component 600 located on the opposite side, so that the dust is no longer stuck in the center of the coating position 210 due to the opposing sides.

[0071] Meanwhile, the lower limit of the tilt angle range (approximately 3°) can avoid in-situ suction and easy secondary fall caused by pure normal adsorption, while the upper limit (approximately 10°) can avoid excessive tangential traction causing film arching, substrate edge disturbance, or local backflow separation. In summary, by setting the axis of the suction port 511 to a small tilt angle of 3°–10° relative to the transmission surface 310 of the conveyor belt 300, a microfluidic field organization that is more conducive to particle lifting, movement, and movement away from the coating interface can be established in the near-field of the coating position 210.

[0072] A particle removal path is formed in the center and near the coating site 210, which first lifts away the particles and then moves them tangentially, significantly reducing residual dust in the central neutral zone.

[0073] This reduces the probability of secondary suspension during pure normal suction and decreases inclusion defects caused by particles falling back to the coating position 210.

[0074] Avoid strong shearing and backflow caused by large angles, and suppress membrane material being lifted by airflow, edge lifting, and disturbance to positioning.

[0075] Together with the trapping effect of the second dust collection component 600 on the opposite side, it forms a synergistic flow guide, shortens the purification time before coating, and improves the coating yield and stability.

[0076] In at least one embodiment of this application, the first vacuuming assembly 500 further includes:

[0077] Air pump 512 is connected to the suction nozzle 510.

[0078] Please refer to Figures 1-4 In this embodiment, the air pump 512 is connected to the suction nozzle 510 through an anti-static flexible pipeline, and an adjustable throttle valve and filter assembly (e.g., pre-filter / medium-efficiency filter element) are provided on the pipeline to stabilize the suction volume and prevent backflow particles from entering the suction nozzle 510.

[0079] During operation, the air pump 512 is continuously driven to establish a stable negative pressure airflow between the suction nozzle 510 and the transmission surface 310 of the conveyor belt 300.

[0080] On the one hand, it provides sufficient volumetric flow rate and pressure difference for the suction nozzle 510 to achieve continuous traction of near-field dust removal and movement direction of the coating position 210.

[0081] On the other hand, through linkage control, the suction is increased before and after the backlight is positioned at the lamination position 210, and the suction is appropriately reduced at the moment the lamination robot 400 presses down to apply the film, so as to avoid airflow disturbing the posture of the lamination material. Combined with the aforementioned small tilt angle e and position asymmetry, the stable negative pressure provided by the air pump 512 ensures that the first dust collection component 500 forms a far-field drainage on the incoming side and works in conjunction with the near-field capture of the second dust collection component 600 on the opposite side, thereby achieving efficient cleaning of the key area of ​​the lamination position 210 before lamination.

[0082] This ensures that the nozzle 510 can maintain effective suction under different operating conditions, reducing secondary suspension of dust caused by negative pressure fluctuations.

[0083] In at least one embodiment of this application, the first vacuuming component 500 and the second vacuuming component 600 have the same structure.

[0084] Please refer to Figures 1-4 In this embodiment, both can be composed of a suction nozzle 510 (with a suction port 511), an air pump 512 connected to the suction nozzle 510, an anti-static and bend-resistant negative pressure pipeline, a filter and throttling unit, and an adjustable mounting bracket.

[0085] The second suction unit 600, which is closer to the centerline of the laminating table 200 and the conveyor belt 300, focuses more on strong suction in the near area, while the first suction unit 500, which is further away, provides drainage and tangential traction from the incoming side.

[0086] In at least one embodiment of this application, the backlight coating device 100 further includes:

[0087] A first guide plate 710 is disposed on the coating stage 200, and a first guide surface 711 is formed at one end away from the coating stage 200.

[0088] The second guide plate 720 is disposed on the film coating stage 200 and is located on both sides of the film coating position 210 with the first guide plate 710. The first dust suction component 500 is located on the first guide plate 710, and the second dust suction component 600 is located on the second guide plate 720. The end of the second guide plate 720 away from the film coating stage 200 forms a second guide surface 721, and a feeding channel 730 is formed between the first guide surface 711 and the second guide surface 721.

[0089] Please refer to Figures 1-4In this embodiment, the first guide surface 711 and the second guide surface 721 are inclined surfaces or rounded transition surfaces that gradually converge toward the coating position 210, so as to provide geometric constraints and lateral correction in the feeding direction and prevent the substrate from swaying and yawing before entering the coating position 210.

[0090] Meanwhile, the first dust collection component 500 is fixedly installed on the first guide plate 710, and the second dust collection component 600 is fixedly installed on the second guide plate 720, with its nozzle 510 and dust collection port 511 pointing towards the feed channel 730 and the near area of ​​the film covering position 210.

[0091] By setting a first guide plate 710 and a second guide plate 720 on the coating table 200 and forming a first guide surface 711 and a second guide surface 721 at their far ends respectively, constructing a feeding channel 730 between the two guide surfaces, and installing the first dust collection component 500 and the second dust collection component 600 on the corresponding guide plates respectively, the coordinated operation of geometric alignment, airflow guidance and near-field capture is realized.

[0092] The convergence geometry of the feed channel 730 completes the passive centering and sway suppression of the substrate before entering the coating position 210, reducing the cleaning blind spot caused by eccentricity.

[0093] The dust collection components carried by the guide plate form a continuous biased flow field from the channel opening to the channel interior to the membrane position 210. Together with the asymmetric positional relationship of a>b (and c>d), it breaks the symmetric counteraction and significantly improves the movement and capture efficiency of dust in the center and near area.

[0094] In at least one embodiment of this application, the film-coating robot 400 includes:

[0095] The adsorption plate 410 has multiple vacuum adsorption holes 411.

[0096] The two-axis drive assembly 420 is mounted on the film covering stage 200 at one end and connected to the adsorption plate 410 at the other end.

[0097] A vacuum pump 440 is mounted on the adsorption plate 410 and communicates with the adsorption holes.

[0098] Please refer to Figures 1-4 In this embodiment, during operation, the coating material is first placed in the placement position 430 on the side where the coating robot 400 is located. After the vacuum pump 440 is started, the coating material is stably adsorbed onto the adsorption plate 410 through the vacuum adsorption hole 411. The two-axis drive assembly 420 drives the adsorption plate 410 to complete the smooth transfer and alignment from the placement position 430 to the coating position 210, and then slowly lowers and applies the coating material above the coating position 210 in a predetermined posture.

[0099] During this process, the short air path and zoned suction control ensure that the membrane material remains attached to the adsorption plate 410 during the handling and alignment stages, preventing the membrane material from bulging, shaking, or lifting at the edges and entraining air and dust. At the same time, in conjunction with the biased airflow established by the first dust collection component 500 and the second dust collection component 600, the time and area of ​​the membrane-substrate interface exposed to residual airflow disturbances are reduced, thereby obtaining cleaner and more stable interface conditions at the moment of membrane deposition.

[0100] By employing a combination of an adsorption plate 410 (with multiple vacuum adsorption holes 411), a two-axis drive assembly 420 (mounted on the side of the coating stage 200), and a vacuum pump 440 (located on the adsorption plate 410 and connected to the vacuum adsorption holes 411) in the coating robot 400, the vacuum channel is shortened, the pressure drop and response lag are reduced, the suction is established and released more quickly, the local desorption and shaking of the membrane material during handling are reduced, and the chance of secondary suspension of particles is reduced.

[0101] Improved alignment and repeatability accuracy; two-axis decoupling; structure based on rigid mounting of the 200-meter coating stage suppresses accumulated tolerances and mechanism oscillations, making the film dropping posture and landing point more controllable, and reducing wrinkles and stress stripes.

[0102] In at least one embodiment of this application, the backlight coating device 100 further includes:

[0103] A robotic arm 800 is placed on the side of the laminating table 200 away from the laminating robotic arm 400, and is used to pick up the backlight on the conveyor belt 300 and place it on the laminating position 210.

[0104] In at least one embodiment of this application, the backlight coating device 100 further includes:

[0105] A picking robot is mounted on the laminating table 200 and is used to place the backlight after lamination on the laminating position 210 onto the conveyor belt 300. The picking robot and the placing robot 800 are positioned opposite each other.

[0106] Please refer to Figures 1-4 In this embodiment, the placement robot 800 is equipped with an end effector for gripping or vacuum adsorbing the backlight substrate and a two-dimensional or three-dimensional alignment sensing unit. Its working path is from the material picking station above the conveyor belt 300 to the material unloading station above the laminating station 210. It is responsible for accurately picking up the backlight from the conveyor belt 300 and placing it in the laminating station 210. Its base is set on the side of the laminating table 200 away from the laminating robot 400, so that the movement range of the placement robot 800 is staggered from the film picking and laminating path of the laminating robot 400, avoiding spatial interference in the front section of laminating.

[0107] The picking robot is also equipped with an end effector and a positioning sensing unit. Its working path is from the pick-up station above the coating station 210 to the unloading station above the conveyor belt 300. It is responsible for transferring the backlight after coating on the coating station 210 back to the conveyor belt 300. It is set opposite to the placement robot 800 (preferably set opposite to the width of the conveyor belt 300 or set on the opposite side of the coating table 200), so that the incoming and outgoing materials form a unidirectional flow.

[0108] After the placement robot 800 places the backlight in the film coating position 210 and exits, the first dust collection component 500 and the second dust collection component 600 establish a biased airflow in the near field of the film coating position 210 to complete the near field cleaning. Then, the film coating robot 400 takes the film from the placement position 430 and applies it in the film coating position 210. After the film coating is completed and the vacuum is released, the retrieval robot enters the film coating position 210 to take away the finished product and puts it back on the conveyor belt 300.

[0109] Within the operating window, the suction volume of the first vacuum assembly 500 and the second vacuum assembly 600 is slightly increased to ensure that the boundary layer disturbance caused by the pick-up and put-down action is promptly drawn to the side closer to the second vacuum assembly 600 and sucked away.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
