Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] like Figures 1-4As shown in the figure, this utility model embodiment provides a focusing back focus device for focusing a lens to be assembled.

[0047] The focusing device includes a frame 1, a focusing device 2, a collimator 3, an image conversion device 4, and an image sensor 5. The frame 1 has mounting bases 11 and support platforms 12 arranged vertically from top to bottom, with through holes in the mounting bases 11. The focusing device 2 includes a mounting platform 21 and a lens focusing assembly. The mounting platform 21 is mounted on the mounting base 11 and spans the through holes. The lens to be assembled is mounted on the mounting platform 21, and the lens focusing assembly is mounted on the mounting platform 21 for focusing the lens. The collimator 3 is mounted on the mounting base 11, located above the mounting platform 21 and coaxial with the lens to be assembled. The collimator 3 is capable of producing... Parallel light is generated and used to simulate an infinite object distance. A target plate is set on the collimator 3, and the lens to be assembled can capture an image of the target plate on the collimator 3. The image sensor 5 is set on the support platform 12, and the image conversion device 4 is set on the image sensor 5 and located below the mounting machine 21. The image conversion device 4 is coaxial with the lens to be assembled and can convert the image of the lens to be assembled into an image that can be received by the image sensor 5. The image sensor 5 then generates alignment data based on the converted image, and the lens alignment assembly aligns the lens to be assembled according to the alignment data.

[0048] It should be noted that the adjustment of the lens to be assembled is to adjust the lens element inside the lens to be assembled. Before adjustment, the lens element is first coated with adhesive. After adjustment, it is then cured by UV light to complete the assembly.

[0049] This refocusing device uses a collimator 3 and an image conversion device 4. The collimator 3 simulates an infinity object distance. The lens to be assembled is imaged through the collimator 3. The image conversion device 4 converts the image from the lens to be assembled into an image that can be received by the image sensor 5. The image sensor 5 predicts and generates refocusing data based on the converted image. The lens refocusing assembly then completes the refocusing based on this data. This method uses orthographic projection for refocusing, and the imaging process is essentially "from object to image." This refocusing method has a simple structure and is easy to operate.

[0050] Optionally, the image conversion device 4 includes a metallurgical objective lens 41 and an adapter tube 42. The adapter tube 42 is fixedly mounted on the image sensor 5, and the metallurgical objective lens 41 is fixedly mounted on the upper end of the adapter tube 42 and located below the mounting base 21. The metallurgical objective lens 41 is coaxial with the lens to be assembled and is used to convert the image of the lens to be assembled. By setting the metallurgical objective lens 41, the image of the lens to be assembled can be converted into an image that can be received by the image sensor 5, so that the image sensor 5 can recognize it. Furthermore, the metallurgical objective lens 41 can also control the size of the image received by the image sensor 5 by changing different magnifications, so as to achieve detail magnification and improve the accuracy of alignment. It should be noted that the target plate on the collimator 3 is small, and the metallurgical objective lens 41 can magnify the image so that the image sensor 5 can recognize it.

[0051] To ensure that the metallographic objective lens 41 is coaxial with the lens to be assembled, the image sensor 5 is mounted on the support platform 12 via the position adjustment component 6. The position adjustment component 6 can adjust the position of the image sensor 5 along the first horizontal direction and the second horizontal direction, thereby enabling the image sensor 5 to move the metallographic objective lens 41. By adjusting the position of the metallographic objective lens 41 along the first horizontal direction and the second horizontal direction, the coaxiality of the metallographic objective lens 41 with the lens to be assembled can be effectively ensured.

[0052] In this embodiment, the vertical direction (Z-axis), the first horizontal direction (X-axis), and the second horizontal direction (Y-axis) are perpendicular to each other.

[0053] Specifically, such as Figures 2-3 As shown, the position adjustment assembly 6 includes a mounting base 61, a first adjustment plate 62, and a second adjustment plate 63. The mounting base 61 is fixedly mounted on the support platform 12. The first adjustment plate 62 is slidably mounted on the mounting base 61 along a first horizontal direction, and the second adjustment plate 63 is slidably mounted on the first adjustment plate 62 along a second horizontal direction. The image sensor 5 is fixedly mounted on the second adjustment plate 63 via a bracket 51. The first adjustment plate 62 is adjustable along the first horizontal direction, thereby adjusting the position of the image sensor 5 along the first horizontal direction, thus enabling the metallurgical objective lens 41 to be adjusted along the first horizontal direction. Similarly, the second adjustment plate 63 is adjustable along the second horizontal direction, thereby adjusting the position of the image sensor 5 along the second horizontal direction, thus enabling the metallurgical objective lens 41 to be adjusted along the second horizontal direction, ensuring that the metallurgical objective lens 41 and the lens to be assembled are coaxial.

[0054] To further improve the adjustment accuracy of the first adjusting plate 62, the mounting base 61 is provided with a first stop surface 611 extending along the first horizontal direction, and the lower end surface of the first adjusting plate 62 is provided with a second stop surface 621 extending along the first horizontal direction. When the first adjusting plate 62 is mounted on the mounting base 61, the first stop surface 611 and the second stop surface 621 slide against each other. When the first adjusting plate 62 slides and adjusts along the first horizontal direction, the first stop surface 611 and the second stop surface 621 slide and cooperate with each other, so that the first adjusting plate 62 has no wobble when sliding, resulting in high adjustment accuracy.

[0055] To further improve the adjustment accuracy of the second adjusting plate 63, the upper end surface of the first adjusting plate 62 is provided with a sliding groove 622 extending along the second horizontal direction, and the lower end surface of the second adjusting plate 63 is provided with a sliding table 631 extending along the second horizontal direction. When the second adjusting plate 63 is placed on the first adjusting plate 62, the sliding table 631 is slidably disposed within the sliding groove 622. By providing the mutually cooperating sliding table 631 and sliding groove 622, the accuracy of the second adjusting plate 63 is improved when adjusted along the second horizontal direction. Of course, the upper end surface of the first adjusting plate 62 can also be provided with a sliding table 631, and the lower end surface of the second adjusting plate 63 can be provided with a sliding groove 622.

[0056] Optionally, the mounting base 61 is provided with at least two first threaded holes 612, and the first adjusting plate 62 is provided with at least two first elongated holes 623 that correspond one-to-one with the first threaded holes 612 and extend along the first horizontal direction. The corresponding first threaded holes 612 and first elongated holes 623 are provided with first screws. When the first screws are loosened, the position of the first adjusting plate 62 can be adjusted along the first horizontal direction through the first elongated holes 623. After the first adjusting plate 62 is adjusted, the first screws are tightened to fix the position of the first adjusting plate 62.

[0057] Optionally, the first adjusting plate 62 is further provided with at least two second threaded holes 624, and the second adjusting plate 63 is further provided with at least two second elongated holes 632 that correspond one-to-one with the second threaded holes 624 and extend along the second horizontal direction. The corresponding second threaded holes 624 and the second elongated holes 632 are provided with second screws. When the second screws are loosened, the position of the second adjusting plate 63 can be adjusted along the second horizontal direction through the second elongated holes 632. After the second adjusting plate 63 is adjusted, the second screws are tightened to fix the position of the second adjusting plate 63.

[0058] To facilitate the position adjustment of the first adjusting plate 62, the mounting base 61 is provided with a first fastening block 64 on at least one side along the first horizontal direction. The first fastening block 64 has a first through hole 641. The side of the first adjusting plate 62 corresponding to the first fastening block 64 has a fourth threaded hole 625 corresponding to the first through hole 641. A fourth screw that is screwed into the fourth threaded hole 625 passes through the first through hole 641. By rotating the fourth screw, the first adjusting plate 62 can be pushed and pulled along the first horizontal direction.

[0059] To facilitate the position adjustment of the second adjusting plate 63, the first adjusting plate 62 is provided with a second fastening block 65 on at least one side along the second horizontal direction. The second fastening block 65 has a second through hole 651. The second adjusting plate 63 has a sixth threaded hole 633 corresponding to the second through hole 651 on the side corresponding to the second fastening block 65. A sixth screw is threaded into the second through hole 651 and connected to the sixth threaded hole 633. By rotating the sixth screw, the second adjusting plate 63 can be pushed and pulled along the second horizontal direction.

[0060] Furthermore, the first fastening block 64 also has a third threaded hole 642, and a third screw is screwed into the third threaded hole 642. After the position of the first adjusting plate 62 is adjusted, the third screw abuts against the first adjusting plate 62. The third screw and the fourth screw cooperate to fix the position of the first adjusting plate 62, so that the first adjusting plate 62 does not move when the first screw is tightened, thus avoiding affecting the adjustment accuracy of the first adjusting plate 62. The second fastening block 65 also has a fifth threaded hole 652, and a fifth screw is screwed into the fifth threaded hole 652. After the position of the second adjusting plate 63 is adjusted, the fifth screw abuts against the second adjusting plate 63. The fifth screw and the sixth screw cooperate to fix the position of the second adjusting plate 63, so that the second adjusting plate 63 does not move when the second screw is tightened, thus avoiding affecting the adjustment accuracy of the second adjusting plate 63.

[0061] Optionally, such as Figure 4 As shown, the lens alignment assembly includes a first adjustment module 221, a second adjustment module 222, and an adsorption module 223. The first adjustment module 221 is mounted on the mounting base 21. The second adjustment module 222 is mounted on the drive end of the first adjustment module 221. The adsorption module 223 is mounted on the drive end of the second adjustment module 222 and is used to adsorb the lens to be aligned with the lens to be assembled. The first adjustment module 221 can drive the adsorption module 223 to move the lens to be aligned along a first horizontal direction, thereby adjusting the lens to be aligned along the first horizontal direction. The second adjustment module 222 can drive the adsorption module 223 to move the lens to be aligned along a second horizontal direction, thereby adjusting the lens to be aligned along the second horizontal direction.

[0062] Optionally, the driving end of the second adjustment module 222 is provided with a supporting horizontal plate 2221; the adsorption module 223 includes a vertical plate 2231, an adsorption end 2232, a counterweight 2233, and a vertical driving module 2234. The vertical plate 2231 is disposed on the supporting horizontal plate 2221. The adsorption end 2232 is slidably connected to one side of the vertical plate 2231 through a first guide rail slider structure. The adsorption end 2232 adsorbs the lens by drawing a vacuum. The counterweight 2233 is slidably connected to the other side of the vertical plate 2231 through a second guide rail slider structure. 3. The adsorption end 2232 is connected by a pull rope. The weight of the counterweight 2233 is greater than the weight of the adsorption end 2232. The vertical drive module 2234 is set on the support plate 2221. The drive end of the vertical drive module 2234 is connected to the adsorption end 2232. The vertical drive module 2234 can drive the adsorption end 2232 to move towards the lens to be adjusted in the vertical direction so that the adsorption end 2232 can adsorb the lens to be adjusted. By setting the counterweight 2233, it is possible to prevent the gravity of the adsorption end 2232 from being too large and thus generating too much pressure on the lens to be adjusted.

[0063] In this embodiment, a pressure sensor is also provided between the adsorption end 2232 and the vertical drive module 2234. The pressure sensor detects the pressure of the adsorption end 2232 so that the lens to be adjusted can be cured under reasonable pressure.

[0064] Furthermore, a UV lamp is provided on the adsorption end 2232. When the adsorption end 2232 presses against the lens to be adjusted for curing, the curing speed can be increased by turning on the UV lamp, thereby improving the assembly efficiency.

[0065] To ensure that the lens to be assembled and the collimator 3 are coaxial, refer to... Figure 2 As shown, the focusing device also includes a third adjustment module 7 and a fourth adjustment module 8. The third adjustment module 7 is fixedly mounted on the mounting base 11, and the fourth adjustment module 8 is located at the drive end of the third adjustment module 7. The mounting platform 21 is located at the drive end of the fourth adjustment module 8. The third adjustment module 7 can drive the mounting platform 21 to move along the first horizontal direction, and the fourth adjustment module 8 can drive the mounting platform 21 to move along the second horizontal direction, so as to realize the adjustment of the lens to be assembled along the first horizontal direction and the second horizontal direction, thereby realizing that the lens to be assembled and the collimator 3 can be coaxial.

[0066] Optionally, the first adjustment module 221, the second adjustment module 222, the third adjustment module 7, and the fourth adjustment module 8 are all linear modules.

[0067] The focusing and refocusing equipment uses orthographic projection to detect and refocus the lens to be assembled, which improves the accuracy of adjustment; and the metallographic objective lens 41 is used to magnify the image so that the image sensor 5 can recognize the image; in addition, after the lens to be assembled is adjusted, the lens to be adjusted is pressed and cured by UV lamp to fix the lens to be adjusted for complete assembly.

[0068] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way.
