Description

Lever-type color ink coating device

This work relates to the technical field of ink coating equipment, and in particular to a lever-type color ink coating device.

Please refer to Figures 1 and 2. The "cast molding method" in the contact lens manufacturing process uses injection molding to create the contact lens shell mold, which consists of upper and lower molds. As shown in Figure 2, for colored contact lenses, a pattern needs to be added to the lower mold M before injection molding. As shown in Figure 1, the pattern is added by placing a color ink cup C into a color ink cup and then placing it upside down on the color ink coating table S. After the color ink cup C moves back and forth on the color ink coating table S, it leaves color ink on the coating position S1 of the color ink coating table S. Then, as shown in Figure 2, the pattern color ink is transferred to the lower mold M by the glue head H adhering to the coating position S1. When the ink cup C moves back and forth on the ink coating table S, in addition to supplying ink to the coating position S1, it is also necessary to scrape off any excess ink to ensure that the nozzle H does not pick up residual ink outside the coating position S1. Therefore, the mechanism that drives the ink cup C must also add the function of pressing the ink cup C to ensure that the ink cup C is tightly attached to the ink coating table S.

In view of this, the purpose of this invention is to provide a lever-type color ink coating device that provides the functions of pressing the ink cup and moving and scraping the color ink.

A slide block 31 is coupled to the first slide rail 411, and a support base 32 is coupled to the second slide rail 412. The first slide rail 411 is disposed on the top of the first driving component 42, and the second slide rail 412 is disposed on the base 10, such that the first slide rail 411 and the second slide rail 412 have a height difference in a second direction L2. The second direction L2 is perpendicular to the mounting plane 10a, and the first direction L1 is parallel to the mounting plane 10a. The first direction L1 and the second direction L2 are perpendicular to each other. As shown in Figure 8, the first driving component 42 in this embodiment is a cylinder, and the cylinder plunger is connected to the side wall 312 of the slide 31. The side wall 312 extends from the slide body 311 towards the base 10. When the plunger is actuated, the plunger pushes the side wall 312 to move parallel to the first direction L1, thereby pushing the slide body 311 and the connecting portion 313 connected to the slide body 311, thereby pushing the support seat 32 to move parallel to the first direction L1. At the same time, it pushes the second driving component 50 and the ink printing nozzle 60 to move parallel to the first direction L1.

The second drive assembly 50 includes a lever assembly 51 and a second drive member 52. The lever assembly 51 includes a support member 511 and a lever member 512 rotatably supported by the support member 511. The second drive member 52 is disposed in the receiving recess 321 of the support seat 32, and the support member 511 is disposed on the support surface 322 of the support seat 32. The support member 511 includes two support arms 511a and a shaft 511b disposed between the two support arms 511a. The two support arms 511a are separated by a predetermined distance, and the lever member 512 is disposed between the two support arms 511a and rotatably coupled to the shaft 511b.

The second drive 52 is a cylinder, whose plunger is connected to one end of the lever 512 and drives the lever 512 to swing around the support 511 in a second direction L2. The ink painting head 60 is rotatably disposed at the other end of the lever 512, such that the ink painting head 60 and the second drive 52 are located on opposite sides of the support 511, and the swing of the lever 512 causes the ink painting head 60 to contact at least one painting position 20b of the ink painting surface 20a of the ink painting table 20.

As shown in Figures 6 and 7, the end of the lever member 512 that is connected to the ink application nozzle 60 has a fork-shaped structure 512a. The ink application nozzle 60 is rotatably disposed within the fork-shaped structure 512a, that is, the ink application nozzle 60 is rotatably connected to the two fork arms of the fork-shaped structure 512a. The retaining structure 323 of the support base 32 extends to a position corresponding to the fork-shaped structure 512a.

The ink coating head 60 includes an ink cup 61 and an ink cup receiving member 62 for housing the ink cup 61. The ink cup receiving member 62 is rotatably disposed on the fork-shaped structure 512a of the lever member 512. The ink cup receiving member 62 has a receiving groove 621 in which the ink cup 61 is received. The receiving groove 621 opens onto the surface of the ink cup receiving member 62 near the ink coating table 20. The ink cup 61 has an ink coating opening 611, which, through the opening of the receiving groove 621, allows ink to be applied to at least one coating position 20b on the ink coating surface 20a of the ink coating table 20.

The ink cup receiving member 62 has multiple positioning members 622 near the surface of the ink coating table 20. When the ink coating head contacts the ink coating table, the positioning members 622 position the ink coating head 60 on the ink coating table 20, and the ink coating opening 611 of the ink cup 61 contacts at least one coating position 20b. In this embodiment, the positioning member 622 is a magnet, which is attracted to the ink coating surface 20a of the ink coating table 20, thereby positioning the ink coating head 60 on the ink coating surface 20a. In this embodiment, the positioning member 622 is disposed on both sides of the receiving groove 621 so that the ink coating nozzle 60 has an average positioning force on both sides of the ink coating surface 20a, so that the ink coating nozzle 611 of the ink cup 61 can be tightly attached to the ink coating surface 20a.

As shown in Figure 8, when the first drive 42 is activated, the ink application nozzle 60 can apply ink at multiple application positions 20b on the ink application surface 20a parallel to the first direction L1. At the same time, the ink application nozzle 60 can scrape away ink from other positions to avoid ink sticking to the nozzle.

The lever-type ink coating device of this invention uses a second drive component to drive the lever assembly to swing in a second direction, allowing the ink coating nozzle to be pressed against the coating position on the ink coating table along the second direction, so that the glue head can be dipped in ink. Moreover, the first drive component drives the stage to move parallel to the first direction, so that the ink coating nozzle can form multiple coating positions on the ink coating table, while scraping away ink in other positions to avoid glue head adhesion.
