Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to an optical lens cleaning device. Background Art

[0002] Currently, the common way to clean an optical lens is that a staff member uses the thumb and the remaining fingers of one hand to hold the opposite sides of the optical lens, and uses a lint-free wiping cloth in the other hand to wipe and clean the optical lens. However, the above cleaning method is difficult to apply to optical lenses with a relatively large outer diameter (more than six inches), because the palm of an ordinary operator cannot control an optical lens of this size. And when the optical lens with a relatively large outer diameter is placed on a fixed carrier and then wiped, the cleaning efficiency is not high. Summary of the Invention

Both the first fixing bracket 411 and the second fixing bracket 412 are plate-shaped.

[0022] In this embodiment, the number of guide rails 42 of the component 4a in each pair is two. The centering push block 43 of the component in each pair is in an inverted L shape, including a horizontal plate 431 and a vertical plate 432; the top end of the vertical plate 432 is connected to one end of the horizontal plate 431, the guide rail 42 passes through the vertical plate 432, and a limiting post 433 is provided on the surface of the vertical plate 432 facing the first fixing bracket 411 of the centering component, and the extending direction of the limiting post 433 is the same as the extending direction of the guide rail 42; when the centering push blocks 43 of a pair of centering components slide along the two guide rails 42 respectively until the limiting posts 433 abut against the first fixing bracket 411, it means that the pair of components 4a reaches the reference position.

Further, a plurality of buffer blocks 44 are provided on the side of each centering push block 43 facing the vacuum chuck to avoid damaging the optical lens when pushing the optical lens and protect the optical lens. The material of each buffer block 44 is rubber.

[0024] Please refer to Figure 4 . During the cleaning operation, the operator first places the single optical lens 9 to be wiped on the vacuum chuck 21, and then pushes and pulls the handle 434 on the centering push block 43 of a pair of centering components 4a, so that the pair of centering push blocks 43 slide along the guide rail 42 to the reference position, and the buffer blocks 44 mounted on the centering push block 43 push the optical lens 9 to be aligned with the center of the vacuum chuck 21. Subsequently, the operator turns on the control switch 6 to start the vacuum generating device 23, so that the optical lens 9 is firmly adsorbed on the vacuum chuck 21. Then the speed regulating motor 311 starts, and the speed regulating motor 311 drives the vacuum chuck 21 to rotate through the transmission mechanism. The operator can then manually clean the surface of the optical lens 9 with a dust-free wiping cloth and a special wiping liquid.

[0025] In a specific application, the aforementioned optical lens is a filter of a red light sensor, and the outer diameter of the optical lens is six inches. In other applications, the aforementioned optical lens can also be a silicon wafer or the like.
