[0032] Among them, after the fixed component 3 fixes the lens, the shifting component 2 carries the inking component 4 to the vicinity of the lens. When it is necessary to coat the arc edge, it switches to the first inking device 41, the inking component 4 does not move, and the fixed component 3 moves; when it is necessary to coat the straight edge, it switches to the second inking device 42, the fixed component 3 does not move, and the inking component 4 moves along the straight edge direction of the lens.

[0033] This embodiment significantly improves the adaptability and ink coating quality of the equipment through the first inking device and the second inking device, wherein the first inking device is specially designed for inking of arc edges, and can keep the inking component stationary when the fixed component is movable, thereby ensuring uniform and accurate inking of the arc edges; the second inking device is used for inking of straight edges, and solves the problems of insufficient or overflowing ink that are prone to occur in inking of straight edges in traditional methods by moving the inking component along the straight edge of the lens while the fixed component is stationary, thereby improving production efficiency and reducing downtime caused by adjusting equipment, while also making operation easier, thereby greatly improving the overall operating efficiency and product quality of the production line.

[0034] Optionally, the first ink coating device 41 and the second ink coating device 42 are both rectangular inkjet pen heads. The inkjet pen heads are rectangular, and the long sides are in the horizontal direction when placed horizontally, and in the vertical direction when set vertically.

This design significantly improves the accuracy of inking and the adaptability of the equipment. Through this complex driving system, the inking machine can quickly adapt to lenses of different shapes and sizes.

[0058] In a preferred alternative, the design of the driving member and the connecting member can be further optimized, such as using a higher performance driver or an improved sliding mechanism to improve the response speed and operation accuracy, especially in a high-output production environment.

[0059] Optionally, the base 21 , the second connecting member 25 , and the third connecting member 26 are all provided with a slide rail 5 , and the second connecting member 25 , the third connecting member 26 , and the fourth connecting member 27 move via the slide rail 5 .

This design ensures that the ink coating assembly can maintain the correct position and posture during the ink coating process, thereby improving the ink coating quality and reducing errors.

[0064] Preferably, the fifth connecting member 442 and the fourth connecting member 27 may be manufactured by alloy materials or reinforced composite materials to improve the durability and vibration resistance of the connecting members.

[0067] In this embodiment, using motors for the rotating shaft 31, the first driving member 43, the second driving member 22, the third driving member 23 and the fourth driving member 24 can significantly improve the motion control accuracy and response speed of the equipment. Using motors as the driving source can achieve more precise speed and position control, which is particularly important for ensuring the quality of ink coating.

[0068] Additionally, electric motor-driven systems generally have better reliability and lower maintenance requirements, which helps reduce long-term operating costs and improves production efficiency.

[0069] Preferably, you can consider using servo motors or stepper motors as alternatives: servo motors can provide higher precision and stronger torque control, suitable for applications that require extremely high precision control, while stepper motors are suitable for occasions that do not require continuous motion due to their simple control method and high cost-effectiveness.

[0070] The design of the automatic inking machine includes a base plate, on which an inking assembly and a fixed rotating shaft are mounted. The inking assembly consists of modules in three directions, namely, X, Y, and Z, and can move in these three directions to adapt to different inking needs. The core structure of the inking assembly includes a rotating motor, and a rotating head is connected to the motor end. An inking arm is installed on each side of the rotating head. The inking arms are respectively installed with inking pen heads in horizontal and vertical directions. A small hole is provided at the inlet of each inking pen head for connecting to an ink tube, and the outlet is designed as a flat port to facilitate the output of ink.

[0071] When working, it can automatically switch between two ink application pen tips according to the ink application needs:

[0072] When it is necessary to apply ink to the arc edge, the system will switch to the horizontal ink application pen head and fix the position of the ink application component, only rotating the shaft around its own axis, and using the short and narrow surface of the ink application pen head to apply ink;

[0073] Conversely, when a straight edge needs to be coated, the system switches to the vertical inking pen head, keeping the shaft stationary, while the inking assembly moves in the X direction, using the length and width of the inking pen head to ink the straight edge;

[0074] This design allows precise control of the ink application position and form to accommodate the ink application requirements of lenses of different shapes and sizes.

[0075] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application.
