Description

Technical Field

[0001] This utility model relates to a lens coating assembly, and more particularly to a lens coating assembly used in the field of lens packaging. Background Technology

[0002] A backlight lens is a light guide component used in liquid crystal display devices. It is usually located in the screen backlight module. Its core function is to convert point light sources or line light sources into uniform surface light sources. By scattering, refraction or reflection, it achieves uniform light distribution, thereby improving screen brightness and display consistency.

[0003] When coating lenses, the lens is usually placed on a carrier tape, and then the tape is coated to package the lens. However, if the coating is done manually, the coating efficiency is poor and residual air bubbles may be left. If the coating is done mechanically by a coating machine, the film and the carrier tape are prone to misalignment, which will affect the coating and packaging effect. Utility Model Content

[0004] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that when coating lenses, manual coating is inefficient and air bubbles may appear on the coating. If mechanical bonding is used, the coating and the carrier tape are prone to misalignment, which will lead to misalignment of the coating and affect the coating and packaging effect.

[0005] To address the aforementioned problems, this utility model provides a lens coating assembly, comprising two support frames. A conveyor bar is fixedly connected to the upper ends of both support frames. An L-shaped positioning plate is fixedly connected to the left end of the conveyor bar. Mounting plates are fixedly connected to both the positioning plate and the rear end of the conveyor bar. Positioning components are rotatably connected to the front ends of the mounting plates. A motor is fixedly connected to the rear end of the left mounting plate. The output end of the motor passes through the mounting plate and is fixedly connected to the adjacent positioning component. A loading tray is inserted into the front end of the positioning component. A carrier belt is wound around the surfaces of the two loading trays. A sealing tray is located above the conveyor bar, and a coating film is wound around the sealing tray. The movable end is bonded to the carrier belt on the adjacent tray. The rear end of the positioning plate is fixedly connected to a second motor. The output end of the second motor moves through the positioning plate and is fixedly connected to a first limiting wheel. The front end of the positioning plate is rotatably connected to the second limiting wheel. The rear end of the conveyor bar is provided with a limiting component, which includes a fixed plate fixedly connected to the rear end of the conveyor bar. The front end of the fixed plate is rotatably connected to two pressure rollers and a support wheel. The upper end of the conveyor bar is also provided with an anti-deviation component, which includes two fixed blocks fixedly connected to both ends of the conveyor bar. Two sliding rods are fixedly connected between the two fixed blocks. The outer surfaces of the two sliding rods are slidably fitted with a stop block.

[0006] In the above-mentioned lens coating assembly, during the process of coating the lens by the carrier tray and the sealing tray, multiple limiting parts are used to limit the carrier tape and the coating, so that the carrier tape and the coating are less likely to deviate during the coating process, effectively avoiding the occurrence of misalignment of the coating and thus improving the coating and packaging effect.

[0007] As a further improvement of this application, two limiting strips are fixedly connected to the upper end of the conveyor strip, the carrier belt is in contact with the conveyor strip, and the carrier belt is located between the two limiting strips.

[0008] As a further improvement of this application, the carrier belt is located between the first limiting wheel and the second limiting wheel. The surface of the positioning plate is chiseled with a receiving groove. The second limiting wheel includes two positioning rods fixedly connected in the receiving groove. The outer surfaces of the two positioning rods are slidably fitted with an adjusting block. The front end of the adjusting block is rotatably connected to a roller, which corresponds to the first limiting wheel.

[0009] As a further improvement of this application, both the support wheel and the pressure roller are located on the right side of the conveyor bar, with the support wheel located below the pressure roller.

[0010] As another improvement of this application, the lower end of the stop block is in contact with the conveyor strip, and the lower end of the stop block is provided with anti-slip texture.

[0011] As another improvement of this application, a positioning block is fixedly connected to the front end of the mounting plate on the left side, and a distance sensor is fixedly connected to the left end of the positioning block.

[0012] In summary, in practical applications, the carrier belt is wound around two trays. Motor 1 drives one tray to rotate, causing the carrier belt to move and pull the other tray to rotate. First, pressure rollers and support wheels limit the carrier belt, ensuring it is positioned above the conveyor belt. Two limiting strips are located on either side of the carrier belt, effectively preventing belt deviation. When a lens is placed on the carrier belt and moved to the left tray, the film on the sealing tray passes under the slide bar and rollers and adheres to the carrier belt. Motor 2 drives limiting wheel 1 to rotate, not only moving the carrier belt but also, along with the rollers, squeezing the carrier belt and film together, ensuring they adhere tightly. This prevents belt and film deviation during the lamination process, effectively avoiding misalignment and improving the lamination packaging effect. Attached Figure Description

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4The following is shown: A lens coating assembly includes two support frames 1. A conveyor strip 2 is fixedly connected to the upper ends of both support frames 1. Two limiting strips 13 are fixedly connected to the upper ends of the conveyor strip 2. A carrier belt 8 contacts the conveyor strip 2 and is located between the two limiting strips 13. The two limiting strips 13 limit the carrier belt 8, effectively preventing it from shifting during movement. An L-shaped positioning plate 3 is fixedly connected to the left end of the conveyor strip 2. Mounting plates 4 are fixedly connected to both the positioning plate 3 and the rear end of the conveyor strip 2. Positioning components 5 are rotatably connected to the front ends of the mounting plates 4. The positioning components 5 can be bolts, flanges, or other mounting parts, which can be selected by technicians according to the actual situation. A motor 6 is fixedly connected to the rear end of the left mounting plate 4. The output end of the motor 6 movably passes through the mounting plate 4 and is fixedly connected to the adjacent positioning component 5. The front end of the positioning component 5 is inserted... A carrier tray 7 is provided. A motor 6 drives one of the carrier trays 7 to rotate, causing the carrier belt 8 to move and pull the other carrier tray 7 to rotate. The carrier belt 8 is wound around the surface of the two carrier trays 7. A sealing tray 9 is provided above the conveyor bar 2. A film is wound on the sealing tray 9. The movable end of the film is bonded to the carrier belt 8 on the adjacent carrier tray 7. During the movement of the carrier belt 8, the film on the sealing tray 9 also rotates to the surface of the carrier belt 8. A limiting component is provided at the rear end of the conveyor bar 2. The limiting component includes a fixed plate fixedly connected to the rear end of the conveyor bar 2. Two pressure rollers 14 and a support wheel 15 are rotatably connected to the front end of the fixed plate. The support wheel 15 and the pressure rollers 14 are both located on the right side of the conveyor bar 2, and the support wheel 15 is located below the pressure rollers 14. The support wheel 15 limits the carrier belt 8 before it moves above the conveyor bar 2, so that the carrier belt 8 will not be lifted or squeezed when it is on the conveyor bar 2.

[0024] Figure 1 , Figure 2 , Figure 3 and Figure 5The following diagram shows: A second motor 10 is fixedly connected to the rear end of the positioning plate 3. The output end of the second motor 10 movably passes through the positioning plate 3 and is fixedly connected to a first limiting wheel 11. A second limiting wheel 12 is rotatably connected to the front end of the positioning plate 3. The second limiting wheel 12 includes two positioning rods 121 fixedly connected in the receiving groove. An adjusting block 122 is slidably sleeved on the outer surface of the two positioning rods 121. A roller 123 is rotatably connected to the front end of the adjusting block 122. The roller 123 corresponds to the first limiting wheel 11. The adjusting block 122 slides on the positioning rods 121, which can adjust the position of the roller 123 to facilitate the extrusion of carrier belts 8 and films of different thicknesses. The second motor 10 drives the first limiting wheel 11 to rotate, which not only moves the carrier belt 8, but also, together with the roller 123, extrudes the carrier belt 8 and the film during the movement, so that the carrier belt 8 and the film adhere to each other. An anti-deviation component is also provided at the upper end of the conveyor strip 2. The anti-deviation component includes two fixed components. Fixed blocks are connected to both ends of the conveyor strip 2. Two sliding rods 16 are fixedly connected between the two fixed blocks. The outer surfaces of the two sliding rods 16 are slidably fitted with a stop block 17. The lower end of the stop block 17 is in contact with the conveyor strip 2, and the lower end of the stop block 17 is provided with anti-slip texture, so that the stop block 17 can move. The anti-slip texture can increase the friction between the stop block 17 and the conveyor strip 2, thereby effectively preventing the stop block 17 from shaking when the film is moved. The carrier belt 8 is located between the first limiting wheel 11 and the second limiting wheel 12. The surface of the positioning plate 3 is chiseled with a receiving groove. When the film is in contact with the carrier belt 8, the film first passes through the lower sliding rod 16. The two stop blocks 17 limit the film, effectively preventing the film from shifting to the left or right. Then the film is located below the roller 123 and in contact with the carrier belt 8. By rotating the first limiting wheel 11, it is squeezed together with the roller 123 to make the film in contact with the carrier belt 8, thereby completing the film covering operation.

[0025] When laminating the lens, the carrier belt 8 is wound around two trays 7. One of the trays 7 is rotated by motor 6, which moves the carrier belt 8 and pulls the other tray 7 to rotate. The carrier belt 8 is first limited by pressure roller 14 and support wheel 15, so that the carrier belt 8 is above the conveyor bar 2. Two limiting bars 13 are located on both sides of the carrier belt 8, which effectively prevents the carrier belt 8 from deviating. When the lens is placed on the carrier belt 8 and moves to the tray 7 on the left, the film on the sealing tray 9 passes under the slide bar 16 and roller 123 and is in contact with the carrier belt 8. Motor 2 drives limiting wheel 11 to rotate, which not only moves the carrier belt 8, but also, together with roller 123, squeezes the carrier belt 8 and the film during the movement, so that the carrier belt 8 and the film are in contact with each other, covering the lens and completing the packaging. Therefore, during the lamination process, it is not easy for the carrier belt 8 and the film to deviate, which effectively avoids the phenomenon of misalignment of the film and improves the lamination and packaging effect.

[0026] Second implementation method:

[0027] This embodiment adds a positioning block 18 and a distance sensor 19 to the first embodiment, while the rest remains the same as the first embodiment.

[0028] Figure 6 As shown: A positioning block 18 is fixedly connected to the front end of the mounting plate 4 on the left side, and a distance sensor 19 is fixedly connected to the left end of the positioning block 18.

[0029] During the film coating process of the rotating tray 7, the distance between the carrier tape 8 inside the left tray 7 and the distance sensor 19 is monitored in real time by the distance sensor 19. As the carrier tape 8 rotates, the number of turns of the carrier tape 8 on the left tray 7 also increases, which increases the distance between the carrier tape 8 inside the left tray 7 and the distance sensor 19. After the carrier tape 8 inside the left tray 7 has been wound a certain number of times, the distance sensor 19 transmits a signal to the external controller, which makes it convenient for the staff to replace the tray 7.

[0030] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
