Description

[0002] The contact lens full inspection vision system has requirements for imaging accuracy and stability. The optical components in the lighting and imaging light paths need to ensure that their respective installation centers are located on the optical axis of the light path. That is, the installation of the optical components needs to ensure center alignment to obtain an imaging effect that meets the design requirements.

[0003] The existing optical path alignment method uses the position of the light spot in the camera image to determine whether it is aligned. The current imaging station design requires the camera to observe the light spot position at least two positions, so the camera needs to be moved when actually observing the next light spot position. However, it is difficult to effectively correct the camera's movement position, resulting in the camera's position error introducing an optical path alignment error when the camera is introduced into the optical path again, affecting the imaging effect.

[0034] To facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with examples and drawings. Specific implementation methods of the present invention will be described below. It should be pointed out that in the specific description of these implementation methods, in order to provide a concise description, this specification cannot provide a detailed description of all features of the actual implementation methods.

[0035] refer to Figures 1 to 7 As shown, the utility model provides a visual system correction mechanism, including a light source 1, a first aperture 100, a second aperture 200, a camera 300, a moving mechanism 2 and an adjusting mechanism 3, wherein the moving mechanism 2 is used to drive the second aperture 200 to move so that the second aperture 200 is aligned with the first aperture 100, and after the first aperture 100 is aligned with the second aperture 200, the adjusting mechanism 3 drives the camera 300 to move so that the camera 300 is aligned with the second aperture 200.

[0036] refer to Figure 1 , 2As shown, in this embodiment, the first aperture 100 is a clear aperture, and the optical axis of the light source 1 smoothly forms a light spot on the clear aperture. In actual application, the optical axis of the light source 1 first passes through the first aperture 100 to form a light spot on the first aperture 100. Specifically, the second apertures 200 can be arranged in multiple rows, and the second apertures 200 are placed and distributed along a straight line. The second apertures 200 are driven to move along the straight line by the moving mechanism 2, so that the second apertures 200 to be aligned in the next row are aligned with the first aperture 100. The second apertures 200 can be moved along the straight line so that the next second aperture 200 can be aligned with the first aperture 100. 0, so that the optical axes of the second aperture 200 and the first aperture 100 are coaxial, and the positioning is accurate. Then, the position of the camera 300 is adjusted by the adjustment mechanism 3, so that the camera 300 can be adjusted along the straight line direction to quickly align with the next row of second apertures 200. Similarly, when the second aperture 200 to be aligned is replaced, the above operation is repeated to align the camera 300 with another row of second apertures 200, so that the camera 300 can be quickly corrected so that the camera 300 is aligned with the second aperture 200, and the first aperture 100, the second aperture 200 and the camera 300 are coaxially aligned, so that the camera 300 and the second aperture 200 are cleverly aligned. The aperture 200 is adjusted in the same direction to adapt to different second apertures, and the camera 300 is quickly corrected to prevent the camera 300 from moving and being difficult to correct, thereby effectively avoiding the installation error of the camera 300, improving the positioning accuracy of the camera 300, and improving the imaging effect. Specifically, since a plurality of second apertures 200 are provided, the first debugging aperture used by the second aperture 200 is aligned with the first aperture 100 and the camera 300, and the remaining second apertures 200 are sequentially used as the first working aperture, the second working aperture, ... and so on N working apertures, so as to orderly distinguish the second apertures 200, and the camera 300 is aligned with different second apertures. When the second aperture 200 is aligned, the moving mechanism 2 is first used to drive the second aperture 200 to move as a whole, so that the first working aperture or the second working aperture replaces the debugging aperture to be aligned with the first aperture 100. The position of the camera 300 is driven by the adjusting mechanism 3. The camera 300 can be adjusted to smoothly align with the first working aperture or the second working aperture. The position of the camera 300 is reversely corrected by the first working aperture or the second working aperture. The correction and adjustment of the camera 300 is convenient, and the movement position of the camera 300 is prevented from being difficult to correct, thereby effectively avoiding the installation error of the camera 300, improving the positioning accuracy of the camera 300, and improving the imaging effect.

The three-axis driving mechanism 32 is an XYZ three-axis driving slide, which can smoothly drive the camera 300 to move in the three-axis space and can smoothly align the camera 300 with the second aperture 200.

[0039] In this embodiment, the adjustment mechanism 3 further includes an X-axis fine-tuning member 33 and a Z-axis fine-tuning member 34, the three-axis driving mechanism 32 is drivingly connected to the mounting end of the X-axis fine-tuning member 33, the X-axis fine-tuning member 33 is drivingly connected to the mounting end of the Z-axis fine-tuning member 34, and the Z-axis fine-tuning member 34 is drivingly connected to the camera 300; in actual application, after the first aperture 100 and the second aperture 200 are aligned, the three-axis driving mechanism 32 drives the camera 300 to be roughly positioned, so that the camera 300 is aligned with the light spot, the X-axis fine-tuning member 33 uses an X-axis manual precision slide, and the Z-axis fine-tuning member 34 uses a fine-tuning manual lifting slide, and then the position of the camera 300 is precisely fine-tuned and adjusted by the X-axis fine-tuning member 33 and the Z-axis fine-tuning member 34, and the camera 300 is accurately aligned with the light spot, thereby improving the alignment accuracy of the camera 300; specifically, the first aperture 100, the second aperture 200, and the camera 300 are precisely aligned. 300, X-axis fine-tuning parts 33 and Z-axis fine-tuning parts 34 are arranged in parallel, and each camera 300 is connected to the X-axis fine-tuning part 33 and the Z-axis fine-tuning part 34. After the three-axis driving mechanism 32 drives the X-axis fine-tuning part 33 to move to the specified position, the X-axis fine-tuning part 33 and the Z-axis fine-tuning part 34 respectively adjust the position of the camera 300, so as to accurately adjust the position of each camera 300. Therefore, in the process of aligning the second aperture 200 with the first aperture 100 or the camera 300, several first apertures 100 and second apertures 200 can be aligned synchronously, thereby improving the alignment efficiency. Similarly, after the second aperture 200 moves and aligns with the first aperture 100, in the process of the adjustment mechanism 3 synchronously driving several cameras 300 to move, each camera 300 is accurately aligned with the corresponding second aperture 200, so that several cameras 300 can be corrected synchronously, thereby improving the correction accuracy and efficiency of the camera 300.
