[0002] In the field of laser precision machining, especially in the processing of micron-sized holes, the positioning accuracy of optical lens assemblies is a key factor determining the final processing quality. As the core component of the optical lens assembly, the precision of the lens's mounting posture directly affects the transmission path and focusing effect of the laser beam.
[0003] Traditional lens adjustment devices primarily focus on fine-tuning the lens position by translation within a two-dimensional plane. However, in actual operation, due to errors in the manufacturing and installation processes, the lens inevitably develops slight tilting errors. This makes it difficult to ensure that the incident laser beam is strictly perpendicular to the optical surface of the lens, causing the beam's transmission path after passing through the lens to deviate and severely affecting the final focused spot quality.

[0029] Please refer to the following: Figures 1 to 6 The lens adjustment device provided in the embodiments of this application will now be described. The lens adjustment device is used to adjust the pose of the lens 300, wherein the pose of the lens 300 includes the angle and position of the lens 300.
[0030] Combined with appendix Figure 1 It is understood that the lens adjustment device includes an angle adjustment mechanism 100 and a position adjustment mechanism 200. The position adjustment mechanism 200 is used to adjust the position of the lens 300 in a preset direction. The angle adjustment mechanism 100 is connected to the position adjustment mechanism 200 and is used to adjust the angle of the lens 300. The angle adjustment mechanism 100 includes a fixed plate 10, a movable plate 20, and an adjustment component 30. The movable plate 20 is arranged at a distance from the fixed plate 10. The adjustment component 30 is movably disposed on the fixed plate 10 and connected to the movable plate 20, and is used to drive the movable plate 20 to rotate relative to the fixed plate 10. The movable plate 20 is used to connect the lens 300.
[0031] The preset direction refers to a preset straight line direction. The position adjustment mechanism 200 moves the lens 300 along the preset straight line direction to adjust the position of the lens 300 in that direction. The preset direction can be a single preset straight line direction or multiple intersecting preset straight line directions. The fixed plate 10 is a plate-like structure with high strength and rigidity, serving as a basic support in the angle adjustment mechanism 100. By spacing the movable plate 20 relative to the fixed plate 10, space is provided for the rotation of the movable plate 20.
[0032] Compared with the prior art, the lens adjustment device provided in this application adjusts the position of the lens 300 by moving the lens 300 in a preset direction through the position adjustment mechanism 200; by setting the movable plate 20 of the angle adjustment mechanism 100 and the fixed plate 10 at a relative interval, it provides room for the rotation of the movable plate 20, ensuring smooth angle adjustment; by movably setting the adjustment component 30 on the fixed plate 10 and connecting it to the movable plate 20, when the adjustment component 30 moves relative to the fixed plate 10, the adjustment component 30 drives the movable plate 20 to move relative to the fixed plate 10. Rotating the fixed plate 10 causes the movable plate 20 to rotate the lens 300 synchronously, thereby adjusting the angle of the lens 300. In this way, the angle adjustment mechanism 100 and the position adjustment mechanism 200 are integrated into one, enabling fine-tuning of the angle and position of the lens 300. That is, it can correct the offset of the lens 300 in multiple dimensions, which helps to improve the positioning accuracy of the lens 300 and effectively ensures the perpendicularity between the beam and the mirror surface of the lens 300. This ensures that the beam does not deviate from its transmission path after passing through the center of the lens 300, which helps to improve the quality of the focused spot.
[0033] Furthermore, the adjustment component 30 drives the movable plate 20 to rotate relative to the fixed plate 10, which in turn drives the lens 300 to rotate synchronously, thereby achieving angle adjustment of the lens 300. This simple and stable structure improves the accuracy and stability of the lens 300 angle adjustment, while effectively ensuring the long-term stable operation of the angle adjustment function. Additionally, precise control of the adjustment component 30 allows for minute adjustments to the lens 300 angle, making operation convenient and providing high flexibility and precision in adjusting the lens 300 angle.
[0034] Combined with appendix Figures 1 to 3 It is understood that the adjustment assembly 30 includes a first adjustment member 31 and a first tensioning member 32. The first adjustment member 31 is movably inserted through the fixed plate 10 and one end abuts against the movable plate 20, and is used to push the movable plate 20 to rotate relative to the fixed plate 10. The first tensioning member 32 connects the fixed plate 10 and the movable plate 20 and is used to apply a preload force toward the fixed plate 10 to the movable plate 20.
[0035] For example, in the initial state, the first tensioning member 32 connects the fixed plate 10 and the movable plate 20, and applies a preload force toward the fixed plate 10 to the movable plate 20, so that the movable plate 20 and the fixed plate 10 maintain a relatively stable positional relationship. At the same time, the movable plate 20 is always in close contact with one end of the first adjusting member 31. At this time, the movable plate 20 is in the initial angle position relative to the fixed plate 10, and the lens 300 maintains the initial angle state with the movable plate 20.
[0036] When it is necessary to adjust the angle of the lens 300, an external force is applied to the first adjusting member 31, causing the first adjusting member 31 to move along the direction through the fixed plate 10. The first adjusting member 31 overcomes the pre-tightening force of the first tensioning member 32 and pushes the movable plate 20 to rotate relative to the fixed plate 10, thereby driving the lens 300 or driving the position adjustment mechanism 200 and the lens 300 to rotate synchronously, so as to change the angle of the lens 300.
[0037] Once the lens 300 angle is adjusted to the correct position, the external force applied to the first adjusting member 31 is stopped. At this time, the preload of the first tensioning member 32 continues to act on the movable plate 20, ensuring that the movable plate 20 remains in close contact with one end of the first adjusting member 31, thereby stably fixing the lens 300 at the adjusted angle position.
[0038] The above technical solution, by having the first adjusting member 31 movably inserted into the fixed plate 10 and with one end abutting against the movable plate 20, allows for precise control of the movement of the first adjusting member 31, which is then converted into the rotation angle of the movable plate 20, thus enabling fine-tuning of the lens 300 angle. The first tensioning member 32 applies a pre-tightening force towards the fixed plate 10 to the movable plate 20, ensuring stable rotation of the movable plate 20 within the balanced force system formed by the thrust of the first adjusting member 31 and the pre-tightening force of the first tensioning member 32 during adjustment, preventing wobbling or shifting during the adjustment process. After the lens 300 angle is adjusted to the correct position, the pre-tightening force of the first tensioning member 32 maintains the state where one end of the first adjusting member 31 continuously abuts against the movable plate 20, preventing the lens 300 angle from shifting due to external factors such as vibration or impact, effectively ensuring the long-term stability of the lens 300 angle after adjustment.
[0039] Combined with appendix Figure 4 It is understood that the fixed plate 10 is provided with a first through hole 11, and the first adjusting member 31 is a screw. The first adjusting member 31 passes through the first through hole 11 and is threadedly connected to the first through hole 11. By rotating the first adjusting member 31, the first adjusting member 31 moves relative to the fixed plate 10 along its own axis, thereby pushing the movable plate 20 to rotate relative to the fixed plate 10, and thus adjusting the angle of the lens 300.
[0040] The above technical solution employs a screw structure for the first adjusting member 31, which is threaded into the first through hole 11 of the fixed plate 10. This threaded engagement provides precise transmission characteristics. By controlling the number of rotations of the first adjusting member 31, the movement distance of the first adjusting member 31 along its own axis is controlled, thereby controlling the rotation angle of the movable plate 20. This achieves minute and controllable adjustment of the lens 300 angle. Furthermore, the threaded engagement has a self-locking characteristic, effectively preventing the first adjusting member 31 from loosening due to the reaction force of the movable plate 20 or external vibration after the lens 300 angle is adjusted to the correct position.
[0041] Combined with appendix Figure 4Optionally, the first through hole 11 is a threaded hole, and the first adjusting member 31 passes through the first through hole 11 and is directly threadedly engaged with the first through hole 11. Alternatively, a threaded sleeve is embedded in the first through hole 11, and the first adjusting member 31 passes through the threaded sleeve and is threadedly engaged with the threaded sleeve.
[0042] Alternatively, the first adjusting member 31 is tightly fitted with the first through hole 11, and by pushing the first adjusting member 31 to move, the first adjusting member 31 pushes the movable plate 20 to rotate relative to the fixed plate 10.
[0043] Combined with appendix Figure 2 It is understood that there are two first adjustment members 31. The two first adjustment members 31 are arranged diagonally relative to the center of the movable plate 20. One first adjustment member 31 is used to push the movable plate 20 to rotate around the first rotation axis F1, and the other first adjustment member 31 is used to push the movable plate 20 to rotate around the second rotation axis F2. The second rotation axis F2 intersects the first rotation axis F1 but is not collinear.
[0044] The above technical solution, by setting two first adjustment members 31 diagonally relative to the center of the movable plate 20, one first adjustment member 31 is used to push the movable plate 20 to rotate around the first rotation axis F1, and the other first adjustment member 31 is used to push the movable plate 20 to rotate around the second rotation axis F2, and the second rotation axis F2 intersects the first rotation axis F1 but is not collinear, realizes the angle adjustment of the lens 300 in two different dimensions, which is beneficial to improving the adjustment accuracy of the lens 300 angle.
[0045] Optionally, the second rotation axis F2 is perpendicular to the first rotation axis F1.
[0046] Combined with appendix Figure 2 Optionally, the fixing plate 10 is generally L-shaped, with two first adjusting members 31 located at opposite ends of the fixing plate 10. Specifically, the fixing plate 10 includes a first plate body 12 and a second plate body 13. One end of the first plate body 12 is connected to one end of the second plate body 13. The length direction of the first plate body 12 is aligned with the first rotation axis F1, and the length direction of the second plate body 13 is aligned with the direction of the second rotation axis F2. One of the first adjusting members 31 is located at the end of the first plate body 12 away from the second plate body 13, and the other first adjusting member 31 is located at the end of the second plate body 13 away from the first plate body 12.
[0047] Combined with appendix Figure 2It is understandable that there are multiple first tensioning members 32, which are distributed at intervals. By setting multiple spaced-out first tensioning members 32, the multiple first tensioning members 32 apply a preload force towards the fixed plate 10 to the movable plate 20 from multiple different positions, making the connection between the movable plate 20 and the fixed plate 10 more stable. At the same time, it makes the preload force on the movable plate 20 more evenly distributed, effectively avoiding the wobbling or displacement of the movable plate 20 due to uneven force during rotation adjustment, thereby ensuring the accuracy and stability of angle adjustment.
[0048] Combined with appendix Figure 2 Optionally, there are two first adjusting members 31, which are arranged diagonally relative to the center of the movable plate 20. There are four first tensioning members 32, in which two first tensioning members 32 and one of the first adjusting members 31 are distributed at intervals along the first rotation axis F1, and the other two first tensioning members 32 and the other first adjusting member 31 are distributed at intervals along the second rotation axis F2.
[0049] The first tensioning member 32 includes an elastic member, the two ends of which are connected to the fixed plate 10 and the movable plate 20 respectively, and the movable plate 20 tends to move toward the fixed plate 10.
[0050] Optionally, the movable plate 20 is provided with a first guide hole, and the first fastening rod 46 further includes a first guide post. One end of the first guide post is connected to the fixed plate 10, and the other end is movably inserted through the first guide hole. The elastic element is a helical spring, which is movably sleeved on the first guide post. Alternatively, the elastic element can also be a spring sheet, etc.
[0051] Combined with appendix Figure 1 and Figure 2 It is understood that the position adjustment mechanism 200 is connected to the fixed plate 10, and the lens 300 is mounted on the movable plate 20 to form a first assembly state; or, the position adjustment mechanism 200 is connected to the movable plate 20, and the lens 300 is mounted on the position adjustment mechanism 200 to form a second assembly state.
[0052] Specifically, in the first assembled state, when it is necessary to adjust the angle of the lens 300, the adjustment component 30 is operated, causing the adjustment component 30 to move relative to the fixed plate 10 and exert a force on the movable plate 20, thereby causing the movable plate 20 to rotate relative to the fixed plate 10. The movable plate 20 causes the lens 300 to rotate synchronously, thus changing the angle of the lens 300, thereby achieving the adjustment of the lens 300 angle. When it is necessary to adjust the position of the lens 300 in a preset direction, the position adjustment mechanism 200 is operated, causing the angle adjustment mechanism 100 and the lens 300 to move in the preset direction. Specifically, operating the position adjustment mechanism 200 causes the fixed plate 10 to move in the preset direction. The movement of the fixed plate 10 is transmitted to the movable plate 20 through the adjustment component 30, causing the movable plate 20 and the lens 300 to move with the fixed plate 10 in the preset direction, thereby changing the position of the lens 300 in the preset direction, thereby achieving the adjustment of the lens 300 position. Figure 1 The left lens adjustment device in the middle.
[0053] In the second assembly state: When it is necessary to adjust the angle of lens 300, operate the adjustment component 30 to move relative to the fixed plate 10, and exert a force on the movable plate 20 to drive the movable plate 20 to rotate relative to the fixed plate 10. The movable plate 20 drives the position adjustment mechanism 200 and lens 300 to rotate, thereby realizing the adjustment of the angle of lens 300. When it is necessary to adjust the position of lens 300 in a preset direction, operate the position adjustment mechanism 200. The position adjustment mechanism 200 drives the lens 300 to move in the preset direction, thereby changing the position of lens 300 in the preset direction, thereby realizing the adjustment of the position of lens 300, such as... Figure 1 The left lens adjustment device in the middle.
[0054] By adopting either the first or second assembly state, the angle adjustment mechanism 100 and the position adjustment mechanism 200 are integrated into one unit, offering flexible assembly options that can be selected based on actual application scenarios and requirements, thus broadening the applicability of the device. Furthermore, integrating the angle and position adjustment functions of the lens 300 into one unit reduces the space occupied by the lens adjustment device, facilitating its installation, debugging, and maintenance.
[0055] Combined with appendix Figure 1 and Figure 2It is understood that the preset direction includes a first direction Z and a second direction Y, and the first direction Z intersects with the second direction Y; the position adjustment mechanism 200 includes a first direction adjustment component 40 and a second direction adjustment component 50, the first direction adjustment component 40 is used to adjust the position of the lens 300 in the first direction Z; the second direction adjustment component 50 is connected to the first direction adjustment component 40, and the second direction adjustment component 50 is used to adjust the position of the lens 300 in the second direction Y.
[0056] In the first assembly state, the second direction adjustment assembly 50 is connected to the fixed plate 10, and the first direction adjustment assembly 40 is used to drive the second direction adjustment assembly 50, the angle adjustment mechanism 100, and the lens 300 to move along the first direction Z. The second direction adjustment assembly 50 is used to drive the angle adjustment mechanism 100 and the lens 300 to move along the first direction Z. Figure 1 The left lens adjustment device in the middle.
[0057] Alternatively, in the first assembly state, the first direction adjustment component 40 is connected to the fixed plate 10. The first direction adjustment component 40 is used to drive the angle adjustment mechanism 100 and the lens 300 to move along the first direction Z. The second direction adjustment component 50 is used to drive the first direction adjustment component 40, the angle adjustment mechanism 100 and the lens 300 to move along the second direction Y.
[0058] In the second assembly state, the second direction adjustment assembly 50 is connected to the movable plate 20, and the lens 300 is mounted on the first direction adjustment assembly 40. The first direction adjustment assembly 40 is used to drive the lens 300 to move along the first direction Z, and the second direction adjustment assembly 50 is used to drive the first direction adjustment assembly 40 and the lens 300 to move along the second direction Y. Figure 1 The right-side lens adjustment device.
[0059] Alternatively, in the second assembly state, the first direction adjustment assembly 40 is connected to the movable plate 20, and the lens 300 is mounted on the second direction adjustment assembly 50. The first direction adjustment assembly 40 is used to drive the second direction adjustment assembly 50 and the lens 300 to move along the first direction Z, and the second direction adjustment assembly 50 is used to drive the lens 300 to move along the second direction Y.
[0060] The above technical solution adjusts the position of the lens 300 in the first direction Z by adjusting the first direction adjustment component 40 and the position of the lens 300 in the second direction Y by adjusting the second direction adjustment component 50. The first direction Z and the second direction Y intersect, so as to achieve fine adjustment of the position of the lens 300 in two different directions, namely the first direction Z and the second direction Y, which is beneficial to improving the position adjustment accuracy of the lens 300.
[0061] Optionally, the first direction Z is perpendicular to the second direction Y. For example, the first direction Z is vertical and the second direction Y is horizontal, or the first direction Z is horizontal and the second direction Y is vertical.
[0062] Optionally, the first rotation axis F1 is parallel to the first direction Z, and the second rotation axis F2 is parallel to the second direction Y.
[0063] Understandably, the angle adjustment mechanism 100 can fine-tune the angle of the lens 300 in the first direction Z and the second direction Y, and the position adjustment mechanism 200 can fine-tune the position of the lens 300 in the first direction Z and the second direction Y. This achieves fine-tuning of the lens 300 in four different dimensions, which helps to improve the positioning accuracy of the lens 300.
[0064] Combined with appendix Figure 4 and Figure 5 It is understood that the first direction adjustment component 40 includes a first base 41, a first movable seat 42 and a first adjustment rod 43. The first movable seat 42 is slidably engaged with the first base 41 along the first direction Z. The first adjustment rod 43 is movably disposed on the first base 41 and acts on the first movable seat 42 to drive the first movable seat 42 to move relative to the first base 41 along the first direction Z. In the first assembly state, the first movable seat 42 is connected to the second direction adjustment assembly 50. When the first adjustment rod 43 moves relative to the first base 41, causing the first movable seat 42 to move relative to the first base 41 along the first direction Z, the first movable seat 42 drives the second direction adjustment assembly 50, the angle adjustment mechanism 100, and the lens 300 to move along the first direction Z, thereby adjusting the position of the lens 300 in the first direction Z. Figure 1 The right-side lens adjustment device.
[0065] Alternatively, in the first assembly state, the first base 41 is connected to the second direction adjustment assembly 50, and the first movable seat 42 is connected to the fixed plate 10. When the first adjustment rod 43 drives the first movable seat 42 to move along the first direction Z, the first movable seat 42 drives the angle adjustment mechanism 100 and the lens 300 to move along the first direction Z, so as to adjust the position of the lens 300 in the first direction Z.
[0066] In the second assembly state, the second direction adjustment assembly 50 is connected to the movable plate 20, the first base 41 is connected to the second direction adjustment assembly 50, and the lens 300 is mounted on the first movable base 42. When the first adjustment rod 43 moves the first movable base 42 along the first direction Z, the first base 41 moves the lens 300 along the first direction Z to adjust the position of the lens 300 in the first direction Z. Figure 1 The left lens adjustment device in the middle.
[0067] Alternatively, the first base 41 is connected to the movable plate 20, the first movable seat 42 is connected to the second direction adjustment assembly 50, and the lens 300 is mounted on the second direction adjustment assembly 50. When the first adjusting rod 43 drives the first movable seat 42 to move along the first direction Z, the first movable seat 42 drives the second direction adjustment assembly 50 and the lens 300 to move along the first direction Z, so as to adjust the position of the lens 300 in the first direction Z.
[0068] Combined with appendix Figure 2 and Figure 4 Optionally, the first base 41 is provided with a first adjustment hole, and the first adjustment rod 43 is a screw rod. The first adjustment rod 43 passes through the first adjustment hole and is threadedly connected to the first adjustment hole, and one end of the first adjustment rod 43 abuts against the first movable seat 42. When the first adjustment rod 43 is driven to rotate relative to the first base 41, the first adjustment rod 43 moves relative to the first base 41 along the first direction Z, thereby pushing the first movable seat 42 to move along the first direction Z, thereby adjusting the position of the lens 300 in the first direction Z.
[0069] In the above technical solution, the first adjusting rod 43 adopts a screw structure and is threadedly engaged with the first adjusting hole of the first base 41. The threaded engagement has precise transmission characteristics. By controlling the number of rotations of the first adjusting rod 43, the movement distance of the first adjusting rod 43 along the first direction Z is controlled, thereby controlling the movement distance of the lens 300 along the first direction Z. This achieves micro-adjustment and controllable adjustment of the position of the lens 300 in the first direction Z. Furthermore, the threaded engagement has a self-locking characteristic, effectively preventing the first adjusting rod 43 from loosening after the lens 300 angle is adjusted to the correct position.
[0070] Optionally, the first adjusting hole is a threaded hole, and the first adjusting rod 43 is directly threaded into the first adjusting hole. Alternatively, a threaded sleeve is embedded in the first adjusting hole, and the first adjusting rod 43 passes through the threaded sleeve and is threaded into the threaded sleeve.
[0071] Optionally, the first direction Z is vertical, and the first movable seat 42 and the first base 41 slide in the first direction Z. A first transition block 421 is provided on the side wall of the first movable seat 42. The top end of the first adjusting rod 43 abuts against the bottom of the first transition block 421. Rotating the first adjusting rod 43 pushes the first transition block 421 upward, causing the first transition block 421 to lift the first movable seat 42. Reverse rotation of the first adjusting rod 43 causes the first movable seat 42 to descend under its own weight and the weight of other components. Figure 4 The right-side lens adjustment device.
[0072] Combined with appendix Figure 4 and Figure 5It is understood that the first base 41 includes a first base body 412 and a second base body 413. The first base body 412 and the second base body 413 are disposed opposite each other on both sides of the first movable seat 42 along the first direction Z. The first adjusting rod 43 is movably inserted through the first base body 412, and one end abuts against the first movable seat 42. The first direction adjusting assembly 40 also includes a first elastic member 44. The first elastic member 44 is located on the side of the first movable seat 42 away from the first adjusting rod 43. One end of the first elastic member 44 is elastically connected to the second base body 413, and the other end of the first elastic member 44 is elastically connected to the first movable seat 42. The first elastic member 44 is used to apply an elastic force along the first direction Z and toward the first adjusting rod 43 to the first movable seat 42. In other words, the elastic preload generated by the first elastic element 44 always presses the first movable seat 42 toward the side opposite to the direction of force applied by the first adjusting rod 43. When the first adjusting rod 43 is operated in the opposite direction or released, the first movable seat 42 moves smoothly in the opposite direction under the elastic force of the first elastic element 44, thus realizing the bidirectional fine adjustment function of the lens 300 in the first direction Z.
[0073] Optionally, the first elastic element 44 may be, but is not limited to, a coil spring and a sheet spring.
[0074] Combined with appendix Figure 5 and Figure 6 It is understood that the first movable seat 42 is provided with a first fixing hole, and the first direction adjustment component 40 also includes a first positioning plate 45 and a first fastening rod 46. The first positioning plate 45 is connected to the first base 41. The first positioning plate 45 is provided with a first strip hole 451. The length direction of the first strip hole 451 is consistent with the first direction Z. The first fastening rod 46 passes through the first strip hole 451 and one end is inserted into the first fixing hole and is fastened to the first movable seat 42. It is used to lock the first movable seat 42 onto the first base 41 after the first movable seat 42 moves to the target position along the first direction Z.
[0075] The above technical solution, by inserting the first fastening rod 46 through the first slotted hole 451 and with one end inserted into the first fixed hole to securely engage with the first movable seat 42, achieves the following: after the first movable seat 42 moves to the target position along the first direction Z, the first fastening rod 46 locks the first movable seat 42 onto the first base 41. This effectively prevents the first movable seat 42 from shifting due to vibration, external forces, or other factors, ensuring the long-term stability of the positional accuracy of the lens 300 in the first direction Z. Furthermore, the length direction of the first slotted hole 451 is consistent with the first direction Z, providing guiding constraints for the movement of the first movable seat 42 along the first direction Z and preventing skewness from deviating from the first direction Z during adjustment.
[0076] Optionally, the first fixing hole is a threaded hole, and the first fastening rod 46 is a threaded rod. The first fastening rod 46 is movably inserted through the first strip hole 451, and one end of the first fastening rod 46 is inserted into the first fixing hole and threadedly engaged with it to achieve a tight fit with the first movable seat 42. During adjustment, simply loosening the first fastening rod 46 is sufficient to move and adjust the first movable seat 42. After adjustment, tightening the first fastening rod 46 completes the locking. The operation is simple and efficient, facilitating quick adjustment of the lens 300's position in the first direction Z.
[0077] Alternatively, a first locking part is provided in the first fixing hole, and a second locking part is provided at one end of the first fastening rod 46. The first fastening rod 46 is movably inserted through the first strip hole 451, and one end of the first fastening rod 46 is inserted into the first fixing hole. The second locking part is engaged with the first locking part.
[0078] Combined with appendix Figures 4 to 6 It is understood that the second direction adjustment component 50 includes a second base 51, a second movable seat 52 and a second adjustment rod 53. The second adjustment rod 53 is movably disposed on the second base 51 and acts on the second movable seat 52 to drive the second movable seat 52 to move relative to the second base 51 along the second direction Y. In the first assembly state, the second base 51 is connected to the first direction adjustment assembly 40, and the second movable seat 52 is connected to the fixed plate 10. When the second adjusting rod 53 moves relative to the second base 51, causing the second movable seat 52 to move relative to the second base 51 along the second direction Y, the second movable seat 52 causes the angle adjustment mechanism 100 and the lens 300 to move along the second direction Y, thereby adjusting the position of the lens 300 in the second direction Y. Figure 1 The right-side lens adjustment device.
[0079] Specifically, in the first assembled state, the second base 51 is connected to the first movable seat 42.
[0080] Alternatively, in the first assembly state, the second movable seat 52 is connected to the first direction adjustment assembly 40, and the first direction adjustment assembly 40 is connected to the fixed plate 10. When the second adjustment rod 53 drives the second movable seat 52 to move along the second direction Y, the second movable seat 52 drives the first direction adjustment assembly 40, the angle adjustment mechanism 100, and the lens 300 to move along the second direction Y, so as to adjust the position of the lens 300 in the second direction Y.
[0081] In the second assembly state, the second base 51 is connected to the movable plate 20, the second movable seat 52 is connected to the first direction adjustment assembly 40, and the lens 300 is mounted on the first direction adjustment assembly 40. When the second adjusting rod 53 drives the second movable seat 52 to move along the second direction Y, the second movable seat 52 drives the first direction adjustment assembly 40 and the lens 300 to move along the second direction Y, thereby adjusting the position of the lens 300 in the second direction Y. Figure 5 The right-side lens adjustment device.
[0082] Specifically, in the second assembly state, the second base 51 is connected to the movable plate 20, the second movable seat 52 is connected to the first base 41, and the lens 300 is mounted on the first movable seat 42.
[0083] Alternatively, the first direction adjustment assembly 40 is connected to the movable plate 20, the second base 51 is connected to the first direction adjustment assembly 40, and the lens 300 is mounted on the second movable base 52. When the second adjustment rod 53 drives the second movable base 52 to move along the second direction Y, the second movable base 52 drives the lens 300 to move along the second direction Y, thereby adjusting the position of the lens 300 in the second direction Y.
[0084] Optionally, the second base 51 is provided with a second adjustment hole, and the second adjustment rod 53 is a screw rod. The second adjustment rod 53 passes through the second adjustment hole and is threadedly connected to the second adjustment hole, and one end of the second adjustment rod 53 abuts against the second movable seat 52. When the second adjustment rod 53 is driven to rotate relative to the second base 51, the second adjustment rod 53 moves relative to the second base 51 along the second direction Y, thereby pushing the second movable seat 52 to move along the second direction Y, and thus adjusting the position of the lens 300 in the second direction Y.
[0085] In the above technical solution, the second adjusting rod 53 adopts a screw structure and is threadedly engaged with the second adjusting hole of the second base 51. This threaded engagement provides precise transmission characteristics. By controlling the number of rotations of the second adjusting rod 53, the movement distance of the second adjusting rod 53 along the second direction Y is controlled, thereby controlling the movement distance of the lens 300 along the second direction Y. This achieves minute and controllable adjustment of the position of the lens 300 in the second direction Y. Furthermore, the threaded engagement has a self-locking characteristic, effectively preventing the second adjusting rod 53 from loosening after the lens 300 angle is adjusted to the correct position.
[0086] Optionally, the second adjusting hole is a threaded hole, and the second adjusting rod 53 is directly threaded into the second adjusting hole. Alternatively, a threaded sleeve is embedded in the second adjusting hole, and the second adjusting rod 53 passes through the threaded sleeve and is threaded into the threaded sleeve.
[0087] The second movable seat 52 and the second base 51 are slidably engaged along the second direction Y. Optionally, the second movable seat 52 is slidably disposed on the upper surface of the second base 51, and a second transition block 511 is provided on the side of the second base 51. A second adjusting rod 53 is movably disposed through the second transition block 511, and one end of the second adjusting rod 53 abuts against the side wall of the second movable seat 52. Figure 6 The left lens adjustment device in the middle.
[0088] Alternatively, the second base 51 is provided with a groove, and the second movable seat 52 is slidably disposed within the groove. Both the first seat body 412 and the second seat body 413 are connected to the first movable seat 42. The second adjusting rod 53 movably passes through the side wall of the second movable seat 52, with one end of the second adjusting rod 53 located within the groove and abutting against the first movable seat 42. Figure 6 The right-side lens adjustment device.
[0089] Combined with appendix Figure 5 and Figure 6 It is understood that the second direction adjustment assembly 50 also includes a second elastic element 54, which applies an elastic force along the second direction Y and toward the second adjustment rod 53 to the second movable seat 52. In other words, the elastic preload generated by the second elastic element 54 always presses the second movable seat 52 toward the side opposite to the direction of force applied by the second adjustment rod 53. When the second adjustment rod 53 is reversed or released, the second movable seat 52 moves smoothly in the opposite direction under the elastic force of the second elastic element 54, realizing the bidirectional fine-tuning function of the lens 300 in the second direction Y.
[0090] Combined with appendix Figure 6 It is understood that the second movable seat 52 is provided with a second fixing hole, and the second direction adjustment assembly 50 also includes a second positioning plate 55 and a second fastening rod 56. The second positioning plate 55 is connected to the second base 51, and the second positioning plate 55 is provided with a second strip hole 551. The length direction of the second strip hole 551 is consistent with the second direction Y. The second fastening rod 56 passes through the second strip hole 551, and one end of the second fastening rod 56 is inserted into the second fixing hole and is fastened to the second movable seat 52. The second fastening rod 56 is used to lock the second movable seat 52 onto the second base 51 after the second movable seat 52 moves to the target position along the second direction Y.
[0091] The above technical solution, by inserting the second fastening rod 56 through the second slotted hole 551, with one end of the second fastening rod 56 inserted into the second fixed hole to securely engage with the second movable seat 52, achieves the following: after the second movable seat 52 moves along the second direction Y to the target position, the second fastening rod 56 locks the second movable seat 52 onto the second base 51. This effectively prevents the second movable seat 52 from shifting due to vibration, external forces, or other factors, ensuring the long-term stability of the positional accuracy of the lens 300 in the second direction Y. Furthermore, the length direction of the second slotted hole 551 is consistent with the second direction Y, providing guiding constraints for the movement of the second movable seat 52 along the second direction Y and preventing deviation from the second direction Y during adjustment.
[0092] Optionally, the second fixing hole is a threaded hole, and the second fastening rod 56 is a threaded rod. The second fastening rod 56 is movably inserted through the second strip hole 551, and one end of the second fastening rod 56 is inserted into the second fixing hole and threadedly engaged with it. During adjustment, simply loosening the second fastening rod 56 allows for the sliding adjustment of the second movable seat 52. After adjustment, tightening the second fastening rod 56 completes the locking process. The operation is simple and efficient, facilitating quick and easy calibration of the lens 300's position in the second direction Y.

The support 70 is slidably mounted on the base 60 along the third direction X. One of the two lens adjusting devices is mounted on the base 60, and the other is mounted on the support 70. The third adjusting rod 80 is movably mounted on the base 60 and acts on the support 70 to drive the support 70 to move along the third direction X.
[0101] The third adjusting rod 80 drives the support base 70 to move relative to the base 60 along the third direction X, thereby driving the lens adjusting device on the support base 70 to move along the third direction X, so as to adjust the distance between the two lens adjusting devices in the third direction X, and realize the distance adjustment of the lens 300 on the two lens adjusting devices in the third direction X.

[0105] Step S13: Calibrate the center coordinates of the first aperture on the beam quality instrument as (X0, Y0).

[0109] Step S22: Adjust the position of the second aperture along the first direction Z and the second direction Y, and calibrate the coordinates (X1, Y1) of the beam from the beam emitting end through the second aperture on the first lens adjustment device to the beam quality meter.

[0113] Step S26: Remove the second aperture.
[0114] Step S30: Adjust the initial gap between the fixed plate 10 and the movable plate 20 of the first lens adjustment device and the second lens adjustment device.

[0116] Step S32: Remove tooling part 400.
[0117] Step S40: Determine whether the error between coordinates (X1, Y1) and coordinates (X0, Y0), and between coordinates (X2, Y2) and coordinates (X0, Y0) is less than a preset value. If yes, proceed to step S50; otherwise, return to step S10.
[0118] For example, the default value is ±50um.
[0119] Step S50: Install lens 300 on the first lens adjustment device, adjust the angle of lens 300, and calibrate the coordinates (X3, Y3) of the beam from the beam emission end through lens 300 on the first lens adjustment device onto the beam quality meter.
[0120] Step S60: Determine whether the error between (X3, Y3) and coordinate (X0, Y0) is less than a preset value. If yes, proceed to step S70; otherwise, return to step S20.
[0121] For example, the default value is ±50um.
