Detailed Implementation

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0018] This invention discloses an ink replenishment device, combined with Figures 1 to 8 As shown, it includes an organic platform 1, on which a feeding mechanism 2, a material handling robot 3, an ink replenishment platform 4, a traversing mechanism 5, and a visual monitoring mechanism 9 are provided. The moving end of the material handling robot 3 is provided with a clamping mechanism 30, the rotating moving end of the ink replenishment platform 4 is provided with a fixture 40, and the moving end of the traversing mechanism 5 is provided with an ink dispensing mechanism 6, wherein: The feeding mechanism 2 is used to transport the carrier 100 loaded with workpieces; The material handling robot 3 is used to pick up the carrier 100 from the feeding mechanism 2 and place it on the fixture 40 of the ink replenishment platform 4; The lateral movement mechanism 5 is used to drive the ink dispensing mechanism 6 to move laterally above the fixture 40; The ink dispensing mechanism 6 is used to inject ink onto the edge of the workpiece on the carrier 100 when the ink replenishment platform 4 drives the fixture 40 to rotate.

[0019] In operation, the aforementioned equipment first utilizes the feeding mechanism 2 to transport a carrier 100 loaded with workpieces. Then, the picking robot 3 picks up the carrier 100 from the feeding mechanism 2 and places it on the fixture 40 of the ink replenishment platform 4. During ink replenishment, the lateral movement mechanism 5 drives the ink dispensing mechanism 6 to move laterally above the fixture 40. As the ink replenishment platform 4 rotates the fixture 40, the ink dispensing mechanism 6 applies ink to the edge of the workpiece on the carrier 100. Compared to existing technologies, this invention uses a method that drives the fixture 40 and the workpiece to rotate together, utilizing the ink dispensing mechanism 6 to apply ink to the edge of the lens workpiece, thereby forming an opaque ink coating layer. This ink replenishment method not only simplifies the structure and is easy to control, but also offers higher ink replenishment efficiency and better ink replenishment quality.

[0020] Please see Figure 5 The feeding mechanism 2 includes a feeding support 20, on which a conveying mechanism 21 is provided. The conveying mechanism 21 is used to convey trays 22, and the trays 22 are loaded with carriers 100 arranged in an array. Specifically, the feeding and discharging ends of the conveying mechanism 21 are respectively provided with a feeding lifting and bearing mechanism 23 and a tray lifting and bearing mechanism 24. The feeding lifting and bearing mechanism 23 is used to lift and load multiple layers of trays with carriers 100. The conveying mechanism 21 is used to convey a single tray 22, and the tray lifting and bearing mechanism 24 is used to lift and load multiple layers of empty trays. The above mechanism has the characteristics of saving space and high feeding efficiency.

[0021] To ensure a compact distribution of the various mechanisms, in this embodiment, the material handling robot 3 and the ink replenishment platform 4 are located between the feeding mechanism 2 and the transverse movement mechanism 5.

[0022] As a preferred embodiment, the material handling robot 3 includes a robotic arm 30, and the moving end of the robotic arm 30 is provided with two gripping mechanisms 30. Specifically, the material handling robot 3 can be a multi-axis robot.

[0023] Please see Figure 1 and Figure 2 The machine base 1 is equipped with an axial rotation drive mechanism 7, the rotation axis of which is parallel to the machine base 1. The ink replenishment platform 4 is located at the moving end of the axial rotation drive mechanism 7. Furthermore, the moving end of the axial rotation drive mechanism 7 is provided with an L-shaped support 70, and the ink replenishment platform 4 is fixed on the L-shaped support 70.

[0024] In the above structure, the axis of rotation of the L-shaped support 70 is parallel to the machine base 1. When the ink filling process is performed, the axial rotation drive mechanism 7 drives the ink replenishment platform 4 to rotate 45 degrees, so that the lens on the carrier 100 is tilted. Then, the ink dotting mechanism 6 is used to dot the ink on the edge of the rotating lens. This tilted rotation ink replenishment method helps to coat the edge of the lens with ink more fully.

[0025] In this embodiment, the carrier 100 is preferably fixed by negative pressure adsorption, combined with Figure 2 , Figure 3 and Figure 8 As shown, the fixture 40 has an inclined slot 41, and the carrier 100 includes an inclined surface 101. The inclined surface 101 fits against the inclined surface of the inclined slot 41, and the carrier 100 is engaged in the inclined slot 41.

[0026] Furthermore, the inclined surface of the inclined slot 41 is provided with a negative pressure hole 42 connected to a negative pressure air source, and the carrier 100 is provided with an adsorption hole 102 connected to the negative pressure hole 42. The workpiece is adsorbed onto the carrier 100 by the negative air pressure in the adsorption hole 102. The above-mentioned negative pressure adsorption method can reliably fix the carrier 100 and the lens workpiece, and also facilitate the loading and unloading of materials.

[0027] Please see Figure 4 and Figure 7 The ink dispensing mechanism 6 includes an ink dispensing needle 60. The machine base 1 is provided with a cleaning and fixing platform 8. The cleaning and fixing platform 8 is provided with a pulley drive assembly 80, a roller 81, and a wiping belt 82. The wiping belt 82 is wrapped around the outside of the pulley drive assembly 80 and the roller 81. The position where the wiping belt 82 passes around the roller 81 forms a V-shaped area 84. The cleaning and fixing platform 8 is provided with two clamping blocks 83 and a clamping drive mechanism for driving the two clamping blocks 83 to move relative to each other. The two clamping blocks 83 are symmetrically arranged on both sides of the V-shaped area 84. When the ink dispensing needle 60 moves to the inside of the V-shaped area 84, the clamping drive mechanism drives the two clamping blocks 83 to move closer to each other and press the V-shaped area 84, thereby cleaning the ink dispensing needle 60 by the running wiping belt 82. In the above structure, by setting a V-shaped area 84 and two loosening blocks 83, the present invention can move the ink dotting needle 60 to the inside of the V-shaped area 84 after the ink dotting mechanism 6 completes one ink injection. Then, the two loosening blocks 83 drive the wiping belt 82 at the position of the V-shaped area 84 to clamp the ink dotting needle 60. The wiping belt 82 wipes the ink dotting needle 60 while it is running, thereby realizing the function of automatic cleaning of the needle. In practical applications, it can be wiped and cleaned once after each injection of ink, effectively improving the quality of ink replenishment processing.

[0028] Based on this, the present invention also relates to an ink replenishment method, which is implemented based on a device, comprising a machine platform 1, wherein the machine platform 1 is provided with a feeding mechanism 2, a material handling robot 3, an ink replenishment platform 4, a traversing mechanism 5, and a visual monitoring mechanism 9; the moving end of the material handling robot 3 is provided with a clamping mechanism 30; the rotating moving end of the ink replenishment platform 4 is provided with a fixture 40; the moving end of the traversing mechanism 5 is provided with an ink dispensing mechanism 6; and the visual monitoring mechanism 9 is used to visually monitor the ink replenishment working area. The method includes: Step S1: The loading mechanism 2 is used to transport the carrier 100 loaded with the workpiece. In step S2, the material handling robot 3 picks up the carrier 100 from the feeding mechanism 2 and places it on the fixture 40 of the ink replenishment platform 4; Step S3: The lateral movement mechanism 5 drives the ink dispensing mechanism 6 to move laterally above the fixture 40; In step S4, when the ink replenishment platform 4 drives the fixture 40 to rotate, the ink dispensing mechanism 6 injects ink onto the edge of the workpiece on the carrier 100.
