Description

Technical Field

[0001] This utility model relates to an adsorption component, and more particularly to an adsorption component for loading lens packaging materials 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. It achieves uniform light distribution through scattering, refraction or reflection, thereby improving screen brightness and display consistency. Adsorption components are required during the lens production and packaging process.

[0003] Existing adsorption assemblies typically use suction nozzles to pick up lenses. For example, Chinese Patent Publication No. CN203199658U discloses a transfer fixture that can provide a transfer fixture that does not scratch optical elements when transferring them from a tray to a fixture used in the next process.

[0004] However, when picking up lenses using the suction nozzle, height deviations can easily occur during assembly of the nozzle, requiring level calibration. However, manual calibration is time-consuming and labor-intensive, affecting lens packaging efficiency. When picking up lenses, some nozzles cannot fully fit the lenses, causing some lenses to fall off or fail to be picked up during movement. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, due to assembly issues, height differences easily occur at the nozzle, and the bottoms of multiple nozzles are not on the same horizontal plane, which affects the adsorption of the lens.

[0006] To address the aforementioned problems, this utility model provides an adsorption assembly for lens packaging and feeding, comprising two support plates. A lateral moving assembly is fixedly connected to the upper ends of both support plates. A longitudinal moving assembly is mounted at the front end of the lateral moving assembly, and a mounting plate is fixedly connected to the front end of the longitudinal moving assembly. Multiple adjusting motors are fixedly connected to both the upper and lower ends of the mounting plate, and a U-shaped plate is fixedly connected to the lower end of the mounting plate. Multiple adjusting rods are located above the mounting plate. The lower ends of the adjusting rods rotatably pass through the mounting plate and the U-shaped plate and are fixedly connected to a suction nozzle. A pulley set is fitted onto the output end of the adjusting motor and the outer surface of the adjacent adjusting rod. The adjusting rod includes an outer rod that rotatably passes through the mounting plate and the U-shaped plate. An inner rod is slidably connected to the inner wall of the outer rod. The lower end of the inner rod is fixedly connected to the suction nozzle via a flange. A fixing ring is fixedly connected to the lower end of the outer rod. A compression spring is fixedly connected to the inner top wall of the fixing ring. The compression spring is sleeved outside the inner rod, and its lower end is fixedly connected to the upper end of the suction nozzle. Multiple grooves are carved into the inner wall of the outer rod, and sliders are provided within the grooves. The sliders are fixedly connected to the inner rod.

[0007] In the above-mentioned lens packaging and loading adsorption assembly, the compression spring and movable inner rod enable the suction nozzle to have a self-adjusting function. During the adsorption process of the lens, even if there is a height deviation at the lower end of the multiple suction nozzles, they can still be in close contact with the lens, thereby effectively improving the stability of the lens during the movement process and thus effectively preventing the lens from falling off during the movement.

[0008] As a further supplement to this application, the output end of the regulating motor moves through the mounting plate, and the upper pulley set and the lower pulley set are staggered.

[0009] As a further supplement to this application, the inner rod is a hollow structure, and an air pipe connector is fixedly connected to the upper end of the inner rod. The air pipe connector, the inner rod, and the suction nozzle are interconnected.

[0010] As a further supplement to this application, multiple grooves are arranged in a ring array around the inner rod, and the width of the slider is the same as the width of the groove.

[0011] As a further supplement to this application, the diameter of the retaining ring is larger than the diameter of the suction nozzle, and the lower end of the compression spring moves through the retaining ring.

[0012] As a further supplement to this application, two positioning plates are fixedly connected to the lower end of the mounting plate, the front end of the positioning plates is fixedly connected to the rear end of the U-shaped plate, and the longitudinal section of the positioning plates is triangular.

[0013] In summary, during practical applications, as the longitudinal moving component drives the mounting plate downwards, the suction nozzles contact the lenses. Some suction nozzles contact the lenses first, causing the inner rod to move upwards and the compression spring to contract upwards until all suction nozzles are in contact with the lenses, thus adsorbing multiple lenses. This effectively avoids adsorption errors caused by suction nozzle height deviations and improves stability during the movement process. Attached Figure Description

Detailed Implementation

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-4 The diagram shows an adsorption assembly for loading lenses into packaging. It includes two support plates 1, with a lateral moving assembly 2 fixedly connected to the upper ends of both support plates 1. A longitudinal moving assembly 3 is mounted on the front end of the lateral moving assembly 2, and a mounting plate 4 is fixedly connected to the front end of the longitudinal moving assembly 3. The lateral moving assembly 2 and the longitudinal moving assembly 3 can drive the mounting plate 4 to move longitudinally and laterally, thereby moving multiple adjusting rods 7 to facilitate lens adsorption. The moving assembly is generally adjusted by a linear motor assembly or a lead screw motor assembly, which is prior art and will not be described in detail here. Multiple adjusting motors 5 are fixedly connected to both the upper and lower ends of the mounting plate 4. Those skilled in the art can adjust them according to actual needs. A suitable model of adjusting motor 5 should be selected, such as Y2-63M1-2-0.18KW. A U-shaped plate 6 is fixedly connected to the lower end of the mounting plate 4. Multiple adjusting rods 7 are provided above the mounting plate 4. The lower end of the adjusting rod 7 moves and rotates through the mounting plate 4 and the U-shaped plate 6 and is fixedly connected to a suction nozzle 8. The output end of the adjusting motor 5 and the outer surface of the adjacent adjusting rod 7 are fitted with a pulley set 9. The output end of the adjusting motor 5 moves and passes through the mounting plate 4. The pulley set 9 located above and the pulley set 9 located below are staggered. Each suction nozzle 8 is controlled by an adjusting motor 5 through the pulley set 9. Multiple adjusting motors 5 are respectively assembled on both sides of the mounting plate 4 and operate independently.

[0026] Figure 5 and Figure 6The diagram shows that the adjusting rod 7 includes an outer rod 71 that rotates through the mounting plate 4 and the U-shaped plate 6. An inner rod 72 is slidably connected to the inner wall of the outer rod 71. The lower end of the inner rod 72 is fixedly connected to the suction nozzle 8 via a flange. A fixing ring 73 is fixedly connected to the lower end of the outer rod 71. A compression spring 74 is fixedly connected to the inner top wall of the fixing ring 73. The compression spring 74 provides a buffering force for the suction nozzle 8 to contact the lens. The diameter of the fixing ring 73 is larger than the diameter of the suction nozzle 8. The lower end of the compression spring 74 movably passes through the fixing ring 73. The compression spring 74 is sleeved outside the inner rod 72, and the lower end of the compression spring 74 is connected to the upper part of the suction nozzle 8. The inner rod 71 is fixedly connected to the outer rod 72. Multiple grooves 75 are carved into the inner wall of the outer rod 71. A slider 76 is provided in the groove 75. The multiple grooves 75 are arranged in a ring array around the inner rod 72. The width of the slider 76 is the same as the width of the groove 75. The slider 76 is fixedly connected to the inner rod 72, which can constrain the inner rod 72 to move only axially. When the pulley group 9 drives the outer rod 71 to rotate, the slider 76 can also drive the inner rod 72 to rotate, and can effectively prevent rotational sway. The inner rod 72 is a hollow structure, and an air pipe connector 10 is fixedly connected to the upper end of the inner rod 72. The air pipe connector 10, the inner rod 72 and the suction nozzle 8 are connected.

[0027] During use, the mounting plate 4 can be moved longitudinally by driving the longitudinal moving component 3. If there is a height difference between multiple suction nozzles 8 during assembly, some suction nozzles 8 will contact the lens first. As the mounting plate 4 moves downward, it will push the inner rod 72 to move upward along the slide groove 75, and the compression spring 74 will contract upward until multiple suction nozzles 8 are in contact with the lens, thus adsorbing multiple lenses. This effectively avoids adsorption errors caused by the height difference of the suction nozzles 8 and improves the stability during the movement.

[0028] Second implementation method:

[0029] This embodiment adds a positioning plate 11 to the first embodiment, while the rest remains the same as the first embodiment.

[0030] Figure 7 As shown: The lower end of the mounting plate 4 is fixedly connected to two positioning plates 11. The front end of the positioning plate 11 is fixedly connected to the rear end of the U-shaped plate 6. The longitudinal section of the positioning plate 11 is triangular.

[0031] When the adjusting motor 5 starts and drives the pulley group 9 to rotate, the U-shaped plate 6 is supported by the positioning plate 11, making it difficult for the U-shaped plate 6 to move. This makes it difficult for the adjusting rod 7 to move due to the tension of the belt, effectively preventing the center of the adjusting rod 7 from moving and improving the stability of the suction nozzle 8 during use.

[0032] 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.
