Description

Technical Field

[0001] This utility model belongs to the field of optical lens processing technology, specifically relating to a multi-lens ink coating device. Background Technology

[0002] Optical lens inking refers to the process of uniformly applying black ink to the frosted surface of a lens edge according to specific technical requirements. The aim is to create a uniform black coating on the lens edge, thus reducing backlighting and minimizing stray light scattering through the frosted surface. Existing inking devices typically use a suction cup to hold the optical lens, which then rotates the lens. A brush or applicator is then manually or mechanically brought close to the lens edge to apply the ink. However, ensuring coaxiality between the lens and the suction cup during lens placement is difficult, leading to uneven ink application during lens rotation. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a multi-lens ink coating device to reduce the deviation when placing lenses and improve the uniformity of ink coating multiple lenses.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A multi-lens ink coating device includes a lifting rod, a working plate connected to the lifting rod, a plurality of first driving assemblies disposed below the working plate, a rotating rod disposed on the first driving assemblies, a suction cup disposed on the rotating rod, and an ink coating assembly disposed on the working plate. The working plate is provided with a plurality of working through holes corresponding to the plurality of rotating rods. The rotating rods pass through the working through holes and penetrate the working plate. A limiting plate is provided on the working plate at a position corresponding to the working through holes, and the limiting plate is provided with limiting holes corresponding to the lenses.

[0006] Furthermore, the ink coating assembly includes a brush head, a bracket connected to the brush head, and a second drive assembly connected to the bracket.

[0007] Furthermore, the brush head is rotatably connected to the bracket via a rotating shaft, and a locking nut is connected to the rotating shaft.

[0008] Furthermore, the second drive component is a single-axis slide, which is used to drive the brush head closer to or away from the edge of the lens.

[0009] Furthermore, the limiting plate is detachably connected to the working plate via connecting bolts.

[0010] Furthermore, the first drive assembly includes a rotary motor and a reducer, with the rotating rod connected to the reducer.

[0011] Furthermore, the working through holes are circular holes, and multiple working through holes are distributed in a ring array on the working plate.

[0012] Furthermore, the second driving component includes a slider and a limit switch corresponding to the slider, the limit switch being electrically connected to the first driving component.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0014] 1. By setting a working plate and a limiting plate, with limiting holes on the limiting plate, the position of the optical lens is fixed when it is placed, the position of the suction cup is fixed, and the suction cup is aligned with the center of the back of the lens, so that the optical lens and the suction cup rotate coaxially, reducing the positional deviation during placement and achieving the effect of uniform ink coating.

[0026] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, a multi-lens ink coating device includes a lifting rod 1, a working plate 2, a first drive assembly 3, a rotating rod 41, a suction cup 42, an ink coating assembly 5, and a limiting plate 6. The lifting rod 1 is mounted on a base 11. The lifting rod 1 is an existing electric lifting rod and is connected to an external foot switch, so that the operation of the lifting rod 1 can be controlled by the foot switch. The working plate 2 is a circular plate and is connected to the top of the piston rod of the lifting rod 1. When the lifting rod 1 is working, it drives the working plate 2 to rise or fall. The first drive assembly 3 is also set on the base 11. There are four first drive assemblies 3, which are arranged in a circular array with the lifting rod 1 as the center. The first drive assembly 3 is located below the working plate 2. The first drive assembly 3 includes a rotary motor 31 and a reducer 32. The rotating rod 41 is connected to the reducer 32. When the rotary motor 31 is working, it drives the rotating rod 41 to rotate through the reducer 32. The suction cup 42 is set on the top of the rotating rod 41. The working plate 2 is provided with four working through holes 21 corresponding to the four rotating rods 41. The working through holes 21 are circular holes. The four working through holes 21 and the four rotating rods 41 are also arranged in a circular array on the working plate 2. The upper end of the rotating rod 41 passes through the working through hole 21 through the working plate 2. The suction cup 42 is located in the upper area of ​​the working plate 2. The limiting plates 6 are positioned on the working plate 2 corresponding to the working through holes 21. Four limiting plates 6 correspond one-to-one with four working through holes 21. Each limiting plate 6 has a limiting hole 61 corresponding to the lens 9. The limiting hole 61 is located directly above the working through hole 21, so that when the lens 9 is placed in the limiting hole 61, the corresponding suction cup 42 can be adsorbed onto the back of the lens 9 through the limiting hole 61. In this embodiment, the suction cup 42 can be a regular suction cup or a vacuum suction cup. The vacuum suction cup is connected to an external vacuum pump via a pipe (the lower end of the vacuum suction cup is rotatably connected to the pipe via a rotary joint). During operation, a negative pressure is generated on the suction cup 42 to facilitate the adsorption of the lens 9.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the ink coating assembly 5 is set on the working plate 2 and corresponds to the position of the working through hole 21. There are four ink coating assemblies 5, and the positions of the four ink coating assemblies 5 correspond one-to-one with the four working through holes 21. The ink coating assembly 5 includes a brush head 51, a bracket 52, and a second drive assembly 53. The second drive assembly 53 is a single-axis slide table. The second drive assembly 53 includes a slider 531, a slide base 533, a lead screw 534, and a drive motor. The two ends of the lead screw 534 are rotatably connected to the slide base 533. The drive motor is set at one end of the slide base 533 and connected to an external foot switch, so that the operation of the drive motor can be controlled by the foot switch. The drive motor is connected to the lead screw 534 to drive the lead screw 534 to rotate. The slider 531 is movably connected to the lead screw 534. When the lead screw 534 rotates, it drives the slider 531 to slide on the slide base 533. When the slider 531 slides on the slide base 533, it moves closer to or away from the working through hole 21. The bracket 52 is connected to the slider 531. The bracket 52 is a T-shaped rod. The brush head 51 is rotatably connected to the bracket 52 via a rotating shaft 54, so that the tilt angle of the brush head 51 can be adjusted to adapt to different edge tilt angles of the lens 8. A locking nut 55 is connected to the rotating shaft 54. The locking nut 55 is a wing nut. By tightening the locking nut 55, the brush head 51 can be fixed at a preset angle. A sponge brush is provided on the side of the brush head 51 near the working through hole 21. When in use, the sponge brush is dipped in ink. The slider 531 is used to move the brush head 51 closer to or away from the edge of the lens 9. When the brush head 51 is close to the edge of the lens 9, the sponge brush is used to apply ink to the edge of the lens 9.

[0029] like Figure 3 and Figure 4 As shown, the second drive assembly 53 also includes a limit switch 532, which is detachably connected to the slide block 533. The position of the lever of the limit switch 532 corresponds to the position of the slider 531. When the slider 531 slides to the predetermined position, it can push the lever to trigger the limit switch 532. The limit switch 532 is electrically connected to the first drive assembly 3, so that the first drive assembly 3 can be powered on and start working, driving the lens 9 to rotate.

[0030] like Figure 2 and Figure 4 As shown, the limiting plate 6 is detachably connected to the working plate 2 by four connecting bolts 62. When different types of lenses 9 need to be edge-coated with ink, different limiting plates 6 can be replaced. The upper limit hole 61 of the limiting plate 6 has a different shape, which corresponds to the shape of different lenses 9 to be coated with ink. Thus, this ink coating device can adapt to different types of lenses 9.

[0031] like Figure 1 , Figure 3 and Figure 5As shown, when using the device in this embodiment, a suitable limiting plate 6 is selected according to the model of the lens 9 waiting to be coated with ink. The shape of the upper limiting hole 61 of the limiting plate 6 matches the lens 9. The four limiting plates 6 are connected to the corresponding positions of the four working through holes 21. The four lenses 9 are placed on the four suction cups 42 respectively. Since the position of the suction cup 42 is fixed, the limiting position of the lens 9 by the limiting hole 61 is also fixed. Therefore, the lens 9 is well coaxial with the suction cup 42 during the placement process. The brush head 51 is adjusted to match the edge of the lens 9. The drive motor of the lifting rod 1 and the second drive assembly 53 is connected to an external foot switch. After the person steps on the foot switch, the lifting rod 1 moves downward, thereby driving multiple limit plates 6 and multiple ink coating assemblies 5 on the work plate 2 to move downward. At the same time, the drive motor works, and the slider 531 drives the brush head 51 to move towards the lens 9. After the slider 531 touches the limit switch 532, the first drive assembly 3 is powered on and starts to work, driving the lens 9 to rotate. At this time, the brush head 51 is attached to the outer edge of the lens 9 to apply ink to the lens 9. After the ink application is completed, the person removes their foot from the foot switch, and the slider 531 drives the brush head 51 to move away from the lens 9. The first drive assembly 3 stops working, the lens 9 stops rotating, and the person uses a suction cup pen to remove the lens 9 and place it in the designated position.

[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 principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
