[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0024] This utility model provides a lens assembly wiping device for automatically wiping and cleaning the lens surface during the lens assembly process. It offers high cleaning efficiency, can clean even hard-to-reach areas of the lens, and facilitates faster industrial automated assembly production. To achieve the device's structural functions, it includes a moving module 1 and a mounting plate 2. The moving module 1 drives the mounting plate 2 to move within space. To provide a cloth for wiping the lens, a receiving roller 3 and a discharging roller 4 are rotatably mounted on the mounting plate 2. Figure 1 As shown, a first drive device 5 can be installed on the mounting plate 2 to drive the take-up roller 3 to rotate, and a material strip is wound around the feed roller 4 to connect to the take-up roller 3. In order to allow the material strip to wipe the lens surface, multiple guide wheels 13 are arranged on the mounting plate 2, and a scraper head 6 is also installed at the bottom of the mounting plate 2. The material strip is configured to pass from the feed roller 4 through the multiple guide wheels 13, through the bottom of the scraper head 6, and then around the take-up roller 3. Figure 1 and Figure 2 As shown, under normal conditions, the rotation of the feeding roller 4 is affected by a certain amount of damping. The first drive device 5 drives the receiving roller 3 to rotate, thereby tightening the material strip at the scraper head 6 position. The multiple guide wheels 13 prevent the material strip from scattering. During operation, the moving module 1 drives the scraper head 6 to move the material strip to the position to be wiped. Then, the first drive device 5 drives the material strip to move. The sharp corner of the material strip that is contacted by the scraper head 6 comes into contact with the lens surface, and the material strip and the lens surface undergo relative displacement, thereby achieving the wiping effect on the lens surface. The moving module 1 controls the spatial position of the scraper head 6, thereby quickly wiping the lens at different positions, thus achieving automated wiping and improving productivity. In some embodiments, in addition to controlling the three-axis movement of the scraper head 6 in space, the moving module 1 can also be used to rotate the scraper head 6. In addition to the moving module 1, other separate drive devices can also be considered to drive the rotation of the scraper head 6. The specific setting is not limited here, so as to wipe the dead corner positions after the lens is installed, thereby improving the applicability of the equipment.

[0025] This utility model provides a lens assembly wiping device, specifically offering a configuration of the scraper head 6. To minimize the contact area of ​​the material strip at the bottom of the scraper head 6, facilitating the wiping of hard-to-reach areas in different parts of the lens, the lower part of the scraper head 6 is arranged in an inverted triangle shape. Figure 2As shown, at this time, the contact surface between the bottom strip of the scraper head 6 and the lens is almost a straight line. Although the wiping area is very small, it can greatly improve the wiping efficiency when the moving module 1 moves. The scraper head 6 can also be set as a hexagon with an inner angle of 150° and a width between 4-10mm. In order to prevent the strip from becoming loose, preferably, an air hole is provided on the bottom surface of the scraper head 6, and an air extraction pipe 7 connected to the air hole is also installed on the scraper head 6. The air extraction pipe 7 is used to drive the strip to adhere to the lower surface of the scraper head 6, reducing the risk of the strip bending during movement.

[0026] This utility model provides a lens assembly wiping device. Considering that the dust wiped during the movement of the conveyor belt cannot be firmly attached to the conveyor belt and carried away, in order to prevent the dust from being carried to other places and affecting lenses or equipment in other positions, a suction head 8 is provided below the mounting plate 2 and near the scraper head 6. The dust is absorbed and removed by the suction head 8 through the suction action. In order to further reduce the impact of dust falling to other positions, a receiving tray can also be provided below the mounting plate 2. Only the scraper head 6 protrudes from the bottom of the receiving tray, and the rest of the receiving tray is closed, thereby effectively reducing the impact of dust falling to other positions of the conveyor belt.

[0027] This utility model provides a lens assembly wiping device, which aims to further enhance the cleaning effect, such as... Figure 2 As shown, an air nozzle 9 can be provided below the mounting plate 2. Preferably, the air nozzle 9 is positioned so that the air blowing direction is towards the scraper head 6. The suction head 8 and the air nozzle 9 are located on both sides of the scraper head 6, so that the dust blown out by the air nozzle 9 can be absorbed by the suction head 8, thereby improving the suction capacity of the suction head 8.

[0028] This utility model provides a lens assembly cleaning device. To prevent the scraper head 6 from making hard contact with the lens surface and causing pressure damage to the lens, the lens also includes a counterweight plate 10, which can be referred to as... Figure 2 As shown, the counterweight plate 10 is slidably mounted on the mounting plate 2 in the vertical direction, and a limiting mechanism is provided at the bottom of the mounting plate 2 to prevent the counterweight plate 10 from sliding directly off the bottom. The scraper head 6 is then fixedly mounted on the counterweight plate 10. When the pressure from the scraper head 6 is too high, the counterweight plate 10 will move upwards to balance the pressure value, thus avoiding damage to the lens surface. To enhance the holding effect of the counterweight plate 10, an elastic element, such as a spring, can also be provided on the mounting plate 2 to drive the counterweight plate 10 downwards (not shown in the figure; the specific setting method is not limited here).

[0029] This utility model provides a lens assembly wiping device. To improve the stability of the conveyor belt movement and prevent the conveyor belt from swaying under the guidance of the guide wheel 13, a positioning roller 11 is installed on the mounting plate 2. Figure 2 As shown, specifically, a second drive device 14 is also installed on the mounting plate 2, and a clamping roller 12 that can approach the positioning roller 11 is configured on the second drive device 14. After the clamping roller 12 and the positioning roller 11 approach each other, they can clamp the material belt, thereby preventing the material belt from swaying and causing the transmission accuracy to deviate or the belt to come off.

[0030] This utility model provides a lens assembly wiping device, specifically a movable module 1 for controlling the movement of the mounting plate 2 to different positions in space. Specifically, the movable module 1 includes a third driving device 101 and a first movable plate 102. Figure 3 and Figure 4 As shown, a third driving device 101 is provided here to drive the first movable plate 102 to move along the first direction, and a second movable plate 103 that can move along the second direction is provided on the first movable plate 102. The first direction and the second direction are set to be perpendicular to each other (that is, they can be defined as the X and Y directions of the horizontal plane). At the same time, the mounting plate 2 is slidably mounted on the second movable plate 103 along the vertical direction, and a fourth driving device 105 is also mounted on the mounting plate 2. The output end of the fourth driving device 105 is provided with an adjusting rod 106 that can rotate eccentrically. The mounting plate 2 is provided with an adjusting groove. Finally, the adjusting rod 106 is movably mounted in the adjusting groove. When the fourth driving device 105 drives the eccentric adjusting rod 106 to rotate, it drives the mounting plate 2 to slide along the vertical direction (that is, the Z-axis position adjustment), thereby ultimately driving the scraper head 6 to move in multiple directions in space.

[0031] The present invention provides a lens assembly wiping device. In some special embodiments, in order to improve the wiping effect, a dispensing valve (not shown in the figure) can also be provided on the mounting plate 2. The nozzle of the dispensing valve is used to point to the surface of the material strip. By filling the dispensing valve with cleaning fluid, the material strip can be wetted to wipe the lens. At this time, the blowing mechanism can be configured to blow hot air to accelerate the drying of residual cleaning fluid.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
