Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to a two-way ink coating machine for optical lenses. Background Art

[0002] With the continuous development of science and technology, optical lenses are not only used in products such as film camera lenses, microscope lenses, telescope lenses, but also in many products such as digital camera lenses, security surveillance camera lenses, vehicle-mounted visual system lenses and aerial drone lenses. Optical lenses have formed a close relationship with human life.

[0003] In the process of processing optical lenses, ink is usually applied around the non-working surface of the optical lens by an ink coating machine, so as to enhance the absorption of edge light and reflected light by the lens and reduce the stray light coefficient of the optical system. Currently, ink coating machines mostly use pneumatic suction cups for fixing. When fixing the optical lens, it is usually necessary to hold the lens by hand and then adsorb one side of the optical lens on the pneumatic suction cup. Since this fixing method cannot effectively calibrate the center, it is easy for the optical lens to deviate from the center of the pneumatic suction cup during fixing, resulting in the displacement of the fixed position of the optical lens, which makes it impossible to effectively apply ink to the optical lens.

[0004] In the utility model with application number: CN202022855117.1 and publication number: CN214310950U, an adjustable optical lens ink coating machine is disclosed. However, when in use, the optical lens and the pneumatic suction cup are still prone to deviation from the center, which causes the fixed position of the optical lens to shift, making it impossible to effectively coat the optical lens with ink.

[0039] When in use, the first driving member 402 drives the bidirectional reverse threaded rod 400 to rotate, thereby bringing the first slider 404 and the second slider 405 closer together, so that the clamping blocks 409 in the two rotating clamping members 401 can approach each other at the same time, thereby clamping the optical lens.

[0040] The contact layer 411 made of flexible rubber material on the clamping block 409 can effectively prevent damage to the lens.

[0047] When in use, the threaded rotating rod 300 can be driven by the third driving member 308, so that the ink coating member 307 on the mounting frame 306 is moved closer to or away from the lifting platform 20, thereby making it more convenient to place the optical lens on the lifting platform 20.

[0048] The third driving member 308 is a motor in the prior art that can realize the functions of the present utility model.

[0049] like Figure 5 As shown, in order to facilitate the replacement or maintenance of the ink outlet part 310, this embodiment is modified on the basis of the above embodiment, and the difference from the above embodiment is that the ink coating part 307 includes an ink bottle 309 and an ink outlet part 310, the ink bottle 309 is arranged above the ink outlet part 310 and plugged with the ink outlet part 310, the ink outlet part 310 is used to export the ink in the ink bottle 309, connecting parts 311 are provided on both sides of the ink outlet part 310, and a connecting groove 312 which is matched with the connecting part 311 is provided on the mounting frame 306, the connecting part 311 is installed in the connecting groove 312 and is fixedly connected to the mounting frame 306 through the connecting part 313, and the connecting part 313 and the mounting frame 306 are detachably connected by bolts.

[0050] When in use, the connecting member 313 is detachably connected to the mounting bracket 306 via bolts, so that the ink outlet member 310 can be disassembled, thereby facilitating the replacement or maintenance of the ink outlet member 310 .

[0051] In order to facilitate the control of ink discharge, the present embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the ink discharge member 310 includes an ink discharge housing 314 and an ink discharge head 315. The top of the ink discharge housing 314 is plugged with the ink bottle 309. The ink discharge housing 314 is provided with an ink discharge channel 316, a mounting cavity 317 and a sliding cavity 318 in sequence from top to bottom.

[0053] When the ink coating is completed, the height of the mounting frame 306 is adjusted by the driving part 305, so that the ink outlet head 315 in the ink outlet part 310 is separated from the optical lens, and the return spring 320 in the mounting cavity 317 drives the ink outlet head 315 to be located at the limiting part 319 in the mounting cavity 317, so that the ink inlet hole 321 on the ink outlet head 315 returns to the sliding cavity 318, so that ink is no longer discharged.

[0054] Working principle of this utility model:

[0055] When the utility model is in use, the lifting and placing platform 20 can be raised to a position cooperating with the bidirectional rotating clamping assembly 40, and then the optical lens to be inked can be placed on the lifting and placing platform 20, and then the bidirectional reverse threaded rod 400 is driven to rotate by the first driving member 402, so that the rotating clamping member 401 on the first slider 404 and the second slider 405 can clamp the optical lens, and then the lifting and placing platform 20 is lowered until it is disengaged from the optical lens, and then the rotating clamping member 401 is driven to rotate by the second driving member 403, so that the optical lens rotates, and then the inking of the optical lens is completed by the inking assembly 30, and the optical lens can be positioned and clamped by the cooperation between the lifting and placing platform 20 and the bidirectional rotating clamping assembly 40.

[0056] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
