[0020] Figure 1 The figure shows a suction cup commonly used to suck the lens in the prior art. The suction cup is installed on a pressing device. When installing the lens, the pressing device is used to press the lens into the frame. The pressing device is generally a cylinder, an electric cylinder or an electric screw, etc. However, the pressing force of the pressing device cannot be guaranteed when installing the lens. In order to ensure the installation accuracy of the lens and to avoid damaging the lens, a floating adaptive component and a flexible component are designed for more accurate lens assembly.

[0021] like Figure 2 As shown, the utility model provides a floating mechanism for lens assembly, including a fixed block 5, a suction cup 1 is installed on the fixed block 5 through a floating adaptive component 2 and a flexible component 3, and a pressure sensor 4 is installed between the floating adaptive component 2 and the flexible component 3 for detecting the downward pressure during downward pressure.

[0022] When installing the lens, since the lens is moved to just above the frame, the lens will be slightly misaligned. Then, when the lens is pressed down, due to its arc shape, the lens will automatically find the installation position during the process of being pressed down into the frame. At this time, under the action of the floating adaptive component 2, the lens can be put in a flexibly installed state, thereby avoiding slight errors in rigid installation and ensuring the accuracy of installation.

[0023] And because the lenses are relatively brittle and cannot withstand greater pressure, after multiple tests, the maximum force that the lenses can withstand is 6N, of which the flexible component 3 can offset part of the force, thereby forming a protective effect on the lenses, and at the same time the pressure sensor 4 is used to detect the value of the downward pressure in real time.

[0024] Please focus on Figure 2 and 3 The floating adaptive component 2 includes a positioning block 207, a mounting block 206 mounted on the positioning block 207, the mounting block 206 is movably mounted on the fixed block 5 through a linear guide rail, the bottom block 205 is mounted on the mounting block 206, and a plurality of through holes 203 are provided in the bottom block 205, the floating block 202 is placed in the through hole 203, and a gap 204 is left between the floating block 202 and the mounting block 206, the suction cup 1 is mounted on the floating block 202, and the floating block 202 is elastically mounted on the positioning block 207 through a spring 1 208, the suction cup 1 is elastically mounted on the bottom block 205 through a spring 209, and a spring plunger is installed between the suction cup 1 and the bottom block 205; the floating block 202 can ensure that there is a gap between the suction cup 1 and the bottom block 205, and the floating block 202 can assist the lens to automatically align with the installation position.

[0025] For further information, please refer to Figure 3 and 4 The floating block 202 is provided with an inclined surface 201, and a corresponding inclined surface is provided in the through hole 203, so that when the lens needs to be tilted, the floating block 202 at the required tilting position is separated from the inclined surface, and the suction cup 1 can drive the lens to fine-tune the position.

[0026] Please focus on Figure 2 The flexible component 3 includes a spring three and a guide column, and the pressure sensor 4 is installed on the fixed block 5 through the spring three and the guide column.

[0027] The working principle of the utility model is:

[0028] When installing the lens, first transfer the lens to the top of the frame, and at the same time, the pressing device aligns the lens with the frame and presses it down. During the installation process, the floating adaptive component 2 can drive the lens to be fine-tuned, and assist the lens to automatically align with the installation position to achieve precise installation; at the same time, the flexible component 3 offsets part of the downward pressure to avoid the lens from breaking.

[0029] The device is designed with a floating adaptive component 2 and a flexible component 3 to assemble the lens more accurately and prevent the lens from being damaged under excessive downward pressure.

[0030] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
