[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0028] Reference below Figure 1-Figure 4 The lens assembly device 1000 according to the embodiment of the utility model is described, and the lens assembly device 1000 is used to assemble the lens a in the lens barrel b. The lens assembly device 1000 includes a chassis 100, a lens limiting mechanism 200, a leveling mechanism 300 and a lens barrel fixing mechanism 400, and the lens limiting mechanism 200, the leveling mechanism 300 and the lens barrel fixing mechanism 400 are all arranged on the chassis 100; it can be understood that the chassis 100 can be roughly in the shape of a rectangular parallelepiped, and the interior of the chassis 100 can be provided with a receiving cavity. Of course, the embodiment of the utility model does not limit the shape of the chassis 100, as long as the chassis 100 can carry the lens limiting mechanism 200, the leveling mechanism 300 and the lens barrel fixing mechanism 400.

[0029] like Figure 1-Figure 2 As shown, further, lens a is movably arranged in the lens limiting mechanism 200. It should be noted that the lens limiting mechanism 200 is used to limit the lens a, but since the lens a needs to be horizontally corrected before assembly, the lens a can be movable in the lens limiting mechanism 200 to adjust the position of the lens a, thereby completing the horizontal correction of the lens a.

[0030] It should be noted that horizontal correction of lens a refers to adjusting the optical axis of lens a to be parallel to the central axis of lens barrel b, and / or adjusting the optical axis of lens a to be parallel to the optical axis of the lens installed in lens barrel b.

[0031] Please continue to refer to Figure 1-Figure 2 Furthermore, the leveling mechanism 300 can move on the chassis 100 and perform horizontal correction on the lens a in the lens limiting mechanism 200, and the lens barrel fixing mechanism 400 is used to fix the lens barrel b; it can be understood that the leveling mechanism 300 moves on the chassis 100, thereby adjusting the position of the lens a to complete the horizontal correction of the lens a.

[0032] Please continue to refer to Figure 1-Figure 2 Further, the lens limiting mechanism 200 and / or the lens barrel fixing mechanism 400 can move on the case 100 to align the lens a with the lens barrel b, so as to complete the assembly of the lens a and the lens barrel b. It can be understood that the lens limiting mechanism 200 can move on the case 100, while the lens barrel fixing mechanism 400 is fixed on the case 100; the lens barrel fixing mechanism 400 can move on the case 100, while the lens limiting mechanism 200 is fixed on the case 100; and both the lens limiting mechanism 200 and the lens barrel fixing mechanism 400 can move on the case 100.

[0033] For example, in this embodiment, the lens limiting mechanism 200 is fixed on the chassis 100. After the leveling mechanism 300 completes the horizontal correction of the lens a, the lens barrel fixing mechanism 400 moves on the chassis 100. When the lens barrel fixing mechanism 400 moves to the relative position of the lens limiting mechanism 200, the lens a can be installed in the lens barrel b. The installation of the lens a can be completed after the lens a and the lens barrel b are fixed by gluing.

[0034] The inventors found in actual research that the assembly process of the lens group requires highly precise assembly equipment and highly skilled techniques, because even a slight error or improper operation may affect the relative position of the lens and the lens barrel, thereby affecting the parallelism of the lens and the lens barrel, or affecting the parallelism between multiple lenses.

[0035] In view of this, according to the lens assembly device 1000 of the embodiment of the utility model, by movably setting the lens a in the lens limiting mechanism 200 and using the leveling mechanism 300 to perform horizontal correction on the lens a, the parallelism between the lens a and the lens barrel b can be accurately controlled, and / or the parallelism between multiple lenses a can be accurately controlled, thereby improving the imaging quality of the optical lens; and, by using the lens assembly device 1000 of the embodiment of the utility model to assemble the lens a and the lens barrel b, the assembly process is simple, which is conducive to improving the production efficiency and product yield of the optical lens.

[0036] Please continue to refer to Figure 1-Figure 2In some embodiments, the leveling mechanism 300 includes a leveling displacement bracket 310 and a leveling head 320. The leveling displacement bracket 310 is fixed to the chassis 100, and the leveling head 320 is arranged on the leveling displacement bracket 310. The leveling head 320 can move on the leveling displacement bracket 310 to move relative to the chassis 100. It can be understood that the leveling head 320 is arranged on the leveling displacement bracket 310 and can move on the leveling displacement bracket 310. When the leveling head 320 moves to the relative position of the lens a, the leveling head 320 can contact the lens a and adjust the position of the lens a to complete the horizontal correction of the lens a. After the correction is completed, the leveling head 320 can be moved to the initial position on the leveling displacement bracket 310 again. By setting the leveling displacement bracket 310 and the leveling head 320, the leveling head 320 can be moved on the leveling displacement bracket 310, so as to facilitate the control of the position of the leveling head 320 and further simplify the assembly process of the optical lens.

[0037] Please refer to Figure 3 In some optional embodiments, the leveling head 320 includes a leveling head body 321 and a plurality of elastic elements 322 with the same specification parameters. The plurality of elastic elements 322 are arranged on the leveling head body 321. When the leveling mechanism 300 performs horizontal correction on the lens a, the plurality of elastic elements 322 contact the lens a to adjust the position of the lens a.

[0038] It should be noted that a plurality of elastic elements 322 with completely identical specification parameters are provided on the leveling head body 321. When the leveling head 320 contacts the lens a and performs horizontal correction on the lens a, the elastic element 322 on the leveling head body 321 may contact the lens a and adjust the position of the lens a. Specifically, for example, when the leveling head 320 calibrates the lens a, a plurality of elastic elements 322 contact the lens a. Since the lens a is movably arranged in the lens limiting mechanism 200, if the elastic forces applied to the plurality of elastic elements 322 are different, the elastic force of the spring will drive the lens a to move, thereby adjusting the position of the lens a, so that the elastic forces of the plurality of elastic elements 322 are the same, thereby achieving horizontal correction of the lens a.

[0039] It can be understood that the elastic element 322 can be a spring, and the specification parameters of the spring include but are not limited to the elastic coefficient of the spring, the total length of the spring, the static length of the spring, etc. Specifically, for example, four springs with the same specification parameters are symmetrically arranged on the leveling head body 321. When the leveling head 320 calibrates the lens a, the four springs are in contact with the lens a. Since the lens a is movably arranged in the lens limiting mechanism 200, if the elastic forces applied to the four springs are different, the elastic forces of the springs will drive the lens a to move, thereby adjusting the position of the lens a to complete the horizontal correction of the lens a.

[0040] Therefore, by providing a plurality of elastic elements 322 with the same specification parameters, the horizontal correction of the lens a can be completed only by the elastic force of the plurality of elastic elements 322, thereby further simplifying the assembly process of the optical lens and improving the accuracy of the optical lens assembly.

[0041] In some optional embodiments, the leveling mechanism 300 further includes a pressure sensing component (not shown), which is disposed on the leveling head 320 and is used to measure the elastic force of the plurality of elastic elements 322. It can be understood that by arranging the pressure sensing component on the leveling head 320, when the leveling head 320 contacts the lens a and adjusts the position of the lens a to complete the horizontal correction of the lens a, the pressure sensing component can measure the elastic force of the plurality of elastic elements 322, and when the elastic forces of the plurality of elastic elements 322 measured by the pressure sensing component are the same, it can be considered that the lens a has completed the horizontal correction.

[0042] Therefore, by using the pressure sensing component to measure the elastic force of multiple elastic elements 322 between the leveling head 320 and the lens a, the horizontal correction of the lens a can be made more accurate, the assembly accuracy of the optical lens assembly can be further improved, and the imaging quality of the optical lens can be improved. In addition, the testing method using the pressure sensing component is simple and convenient, which further reduces the difficulty of assembling the lens a and the lens barrel b, and improves the production efficiency and product yield of the optical lens assembly.

[0043] It should be noted that there may be multiple pressure sensing components, and the multiple pressure sensing components are arranged in a one-to-one correspondence with the multiple elastic elements 322. For example, in this embodiment, four pressure sensing components are arranged on the leveling head 320, and the four pressure sensing components are arranged in a one-to-one correspondence with the four elastic elements 322. The leveling mechanism 300 may also not be provided with a pressure sensing component, and the elastic force of the elastic element 322 may be measured by an external pressure sensor.

[0044] In some optional embodiments, the leveling mechanism 300 further includes an adjusting screw (not shown), which is disposed on the leveling head 320 and is used to adjust the force applied to the elastic element 322 .

[0045] It should be noted that when the elastic element 322 is installed on the leveling head body 321, the elastic element 322 needs to be calibrated to ensure that when the elastic element 322 is subjected to the same force, the end faces of the multiple elastic elements 322 are located in the same horizontal plane. Specifically, for example, when the leveling mechanism 300 is calibrated using a standard part, the multiple elastic elements 322 are in contact with the calibration part. When the elastic forces of the multiple elastic elements 322 are the same, it means that the leveling mechanism 300 has completed the calibration. If the elastic forces of the multiple elastic elements 322 are different, the elastic elements 322 are adjusted using an adjustment screw to make the elastic forces of the multiple elastic elements 322 the same, so as to complete the calibration of the leveling mechanism 300.

[0046] Therefore, the force applied to the elastic element 322 is adjusted by using the adjusting screw to calibrate the leveling mechanism 300, thereby further improving the assembly accuracy of the optical lens assembly and improving the imaging quality of the optical lens.

[0047] Please refer to Figure 1-Figure 3 In some optional embodiments, the leveling mechanism 300 further includes a first motor 331 and a second motor 332, and the leveling displacement bracket 310 includes a first displacement axis 311 and a second displacement axis 312, wherein the first motor 331 is used to drive the leveling head 320 to move along the first displacement axis 311, and the second motor 332 is used to drive the leveling head 320 to move along the second displacement axis 312, and the extension direction of the first displacement axis 311 (such as Figure 1 X direction) and the extension direction of the second displacement axis 312 (such as Figure 1 Z direction) perpendicular.

[0048] Specifically, after placing lens a on the lens limiting mechanism 200, the first motor 331 is started, and the leveling head 320 moves along the first displacement axis 311 so that the leveling head 320 is aligned with the lens a. Then the second motor 332 is started, and the leveling head 320 moves along the second displacement axis so that the leveling head 320 contacts the lens a to perform horizontal correction on the lens a. After the correction is completed, the second motor 332 is started again, and the leveling head 320 leaves the lens. Then the first motor 331 is started again, and the leveling head 320 returns to its initial position.

[0049] Therefore, by using the first motor 331 and the second motor 332 to control the leveling head 320 to move along the first displacement axis 311 and the second displacement axis 312, the position control of the leveling head 320 is more precise, thereby further improving the assembly accuracy of the lens a and the lens barrel b, improving the imaging quality of the optical lens, and at the same time, simplifying the process difficulty of assembling the lens a and the lens barrel b, and improving the product yield and product output.

[0050] Please continue to refer to Figure 1-Figure 3In some optional embodiments, the lens limiting mechanism 200 includes a lens groove 210 and a suction assembly 220. The lens a is movably disposed in the lens groove 210. The suction assembly 220 can suck the lens a and push the lens a out of the lens groove 210. It can be understood that the lens groove 210 has a through hole, and the suction assembly 220 can contact the lens a through the through hole and push the lens a out of the lens groove 210.

[0051] It can be understood that the lens a is movably arranged in the lens groove 210. When the lens barrel b is aligned with the lens a to complete the assembly of the lens a, the lens barrel b is easy to contact the lens a, causing the lens a to be displaced, resulting in the lens a that has completed the horizontal correction to be offset again, and the lens groove 210 may also interfere with the lens barrel b, resulting in the inability to complete the assembly of the lens a and the lens barrel b. Therefore, by setting the suction component 220, when the suction component 220 sucks the lens a, on the one hand, the lens a can be fixed to prevent the lens a from being offset again, and on the other hand, the suction component 220 can also push the lens a out of the lens groove 210 to prevent the lens groove 210 from interfering with the lens barrel b, thereby further improving the assembly accuracy of the assembly of the lens a and the lens barrel b, improving the imaging quality of the optical lens, and at the same time simplifying the process difficulty of assembling the lens a and the lens barrel b, and improving the product yield and product output.

[0052] Please continue to refer to Figure 1-Figure 3 In some optional embodiments, the suction assembly 220 includes a suction pen 221 and a cylinder 222. The suction pen 221 is connected to the cylinder 222. When the gas in the cylinder 222 is extracted, the suction pen 221 can generate suction to absorb the lens a. It can be understood that the suction pen 221 can be extended or shortened to push the lens a out of the lens groove 210, or the suction pen 221 and the cylinder 222 can move in the Z direction at the same time, so that the lens a can be pushed out of the lens groove 210, and the embodiment of the utility model is not limited to this.

[0053] Therefore, by connecting the suction pen 221 and the cylinder 222, the air pressure in the cylinder 222 can be controlled to control the suction and release of the suction pen 221, further improving the assembly accuracy of the lens a and the lens barrel b, improving the imaging quality of the optical lens, and at the same time simplifying the process difficulty of assembling the lens a and the lens barrel b, thereby improving product yield and product output.

[0054] It should be noted that there can be multiple lens limiting mechanisms 200 and leveling mechanisms 300, and the multiple lens limiting mechanisms 200 and the multiple leveling mechanisms 300 are arranged in one-to-one correspondence. Thus, when the optical lens includes multiple lenses a, the multiple lenses a can be horizontally corrected at the same time, further improving the assembly efficiency of the lenses a and the lens barrel b and increasing product output.

[0055] Please continue to refer to Figure 1-Figure 3In some optional embodiments, the lens barrel fixing mechanism 400 includes a third motor 431, a fourth motor 432, a lens barrel displacement bracket 420 and a lens barrel fixing member 410, the lens barrel b is fixed on the lens barrel fixing member 410, the lens barrel fixing member 410 is installed on the lens barrel displacement bracket 420, the lens barrel displacement bracket 420 includes a first lens barrel displacement axis 421 and a second lens barrel displacement axis 422, the third motor 431 can drive the lens barrel fixing member 410 to move along the first lens barrel displacement axis 421, the fourth motor 432 can drive the lens barrel fixing member 410 to move along the second lens barrel displacement axis 422, and the extension direction of the first displacement axis 311 (such as Figure 1 X direction), the extension direction of the second displacement axis 312 (such as Figure 1 Z direction) and the extension direction of the first lens barrel displacement axis 421 (eg Figure 1 The second lens barrel displacement axis 422 and the second lens barrel displacement axis 312 are perpendicular to each other in the Y direction. The extension direction of the second lens barrel displacement axis 422 is the same as the extension direction of the second displacement axis 312.

[0056] Specifically, a snap-fitting portion (not shown) may be provided on the lens barrel fixing member 410, and the lens barrel b may be fixed to the lens barrel fixing member 410 via the snap-fitting portion, or the lens barrel fixing member 410 may also utilize air pressure adsorption to fix the lens barrel b to the lens barrel fixing member 410. The present utility model does not limit the manner in which the lens barrel b is fixed to the lens barrel fixing member 410.

[0057] It can be understood that when the suction component 220 sucks and ejects the lens a, the third motor 431 drives the lens barrel fixing member 410 to move along the first lens barrel displacement axis 421, and the fourth motor 432 can drive the lens barrel fixing member 410 to move along the second lens barrel displacement axis 422, so that the lens barrel b is aligned with the lens a, and the lens a enters the lens barrel b. After the lens a and the lens barrel b are fixed by gluing, the assembly of the lens a and the lens barrel b can be completed.

[0058] Therefore, by utilizing the third motor 431 and the fourth motor 432 to drive the lens barrel fixing member 410 to move along the lens barrel displacement bracket 420, the assembly accuracy of the lens a and the lens barrel b is further improved, the imaging quality of the optical lens is improved, and at the same time, the process difficulty of assembling the lens a and the lens barrel b is simplified, thereby improving the product yield and product output.

[0059] Please refer to Figure 4In some optional embodiments, the lens assembly device 1000 further includes a motor control box 500 and an air pressure control box 600, both of which are disposed in the chassis 100, the motor control box 500 is used to control the start and stop of the first motor 331, the second motor 332, the third motor 431 and the fourth motor 432, and the air pressure control box 600 is used to control the air pressure in the cylinder 222, thereby controlling the suction pen 221 to suck and release the lens a. The chassis 100 is provided with a receiving chamber, and the motor control box 500 and the air pressure control box 600 can be disposed in the receiving chamber. Therefore, the motor control box 500 is used to control the first motor 331, the second motor 332, the third motor 431 and the fourth motor 432, and the air pressure control box 600 is used to control the air pressure in the cylinder 222, so as to further improve the assembly accuracy of the lens a and the lens barrel b, improve the imaging quality of the optical lens, and at the same time simplify the process difficulty of assembling the lens a and the lens barrel b, thereby improving the product yield and product output.

[0060] In some other embodiments, the lens assembly device 1000 may also include a main unit 700 and a display screen 800. The main unit 700 may control the motor control box 500 and the air pressure control box 600. The display screen 800 may display the force measured by the pressure sensing component, the start and stop status of the first motor 331, the second motor 332, the third motor 431 and the fourth motor 432, the air pressure in the cylinder 222 and other data. Of course, the embodiments of the present invention are not limited to this, and the lens assembly device 1000 may not be provided with the main unit 700 and the display screen 800.

[0061] Other structures and operations of the lens assembly device 1000 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
