Description

Technical Field

[0001] This utility model relates to the field of optical technology, specifically to a two-dimensional angle-adjustable lens mount device and a laser. Background Technology

[0002] Lasers are widely used in 3C industry marking and industrial precision machining. The lens mount is the device that fixes the optical lenses in the laser. The stability and adjustability of the optical path in a laser play a crucial role in its performance. As an important component of a laser, the mechanical stability of the adjustable lens mount that supports the optical lenses is particularly important. Existing optical adjustment mounts typically only allow adjustment in one dimension, or both pitch and horizontal directions can only be adjusted by the same adjustment plate, unable to independently adjust the lens angles in two dimensions. During use, this easily leads to a linkage effect between pitch and horizontal angle adjustments, making unidirectional linear adjustment impossible and affecting the accuracy and convenience of optical path adjustment. Furthermore, the integrated adjustment structure makes it difficult to lock the horizontal and vertical directions separately, making it difficult to guarantee the long-term reliability of the laser's output parameters. Utility Model Content

[0003] This application provides a two-dimensional angle-adjustable mirror mount device and a laser, which achieves independent adjustment and locking in the pitch and horizontal directions through independent adjustment components, thus improving the shortcomings of the prior art.

[0004] This application provides the following technical solution:

[0005] A two-dimensional angle-adjustable lens mount device includes a base, a transition plate, a lens mounting plate, a first angle actuator, and a second angle actuator.

[0006] The transition plate includes a plate body and a first rotating shaft arranged in a horizontal direction. The first rotating shaft is connected to the base through a first shaft hole mating structure.

[0007] The lens mounting plate includes a second rotating shaft arranged in a vertical direction, and the second rotating shaft is connected to the transition plate through a second shaft hole fitting structure;

[0008] The first angle actuator can drive the transition plate to rotate relative to the base around the first axis of rotation.

[0009] The second angle actuator can drive the lens mounting plate to rotate relative to the transition plate around the second axis.

[0010] In some implementations, the base is provided with a first groove in the horizontal direction, and the first rotating shaft is rotatably engaged in the first groove.

[0011] In some embodiments, the first shaft hole mating structure includes a first threaded hole disposed on the sidewall of the first groove and a first set screw threadedly engaged with the first threaded hole. The first set screw abuts against the sidewall of the first rotating shaft and is capable of applying a radial force to the first rotating shaft.

[0012] In some embodiments, the second shaft hole mating structure includes a second threaded hole disposed on the sidewall of the second groove and a second set screw threadedly engaged with the second threaded hole. The end of the second set screw abuts against the sidewall of the second rotating shaft and is capable of generating a radial force on the second rotating shaft.

[0013] In some implementations, the transition plate rotates at an angle of ±3°, and the lens fixing plate rotates at an angle of ±3°.

[0014] In some implementations, the lens mounting plate is provided with a lens mounting position, on which an optical lens is mounted.

[0016] In some embodiments, the first angle actuator and the second angle actuator are angle adjustment assemblies with identical structures. The angle adjustment assembly includes a main body, a fixed pin, a movable pin, and an adjusting screw. One end of the adjusting screw abuts against the movable pin and can apply a radial force to the movable pin, causing the movable pin to slide on a side wall of the main body, thereby changing the relative position of the fixed pin and the movable pin.

[0017] In some embodiments, a third mounting hole is provided at the end of the transition plate away from the first rotating shaft, and a first mounting hole is provided on the base.

[0020] Beneficial effects:

[0021] The two-dimensional angle-adjustable lens mount device provided in this application, through the shaft-hole mating structure between the transition plate, the lens mounting plate, and the base, allows the transition plate and the lens mounting plate to rotate integrally around the axis between the transition plate and the base in the pitch direction, thereby achieving lens angle adjustment in the pitch direction. Furthermore, the lens mounting plate can rotate horizontally around the fixed axis between itself and the transition plate, changing the angle between the lens mounting plate and the transition plate, thus achieving lens angle adjustment in the horizontal direction. This device has a simple structure, and horizontal and pitch rotation adjustments of the lens can be easily completed through simple operation. The two dimensions of angle adjustment are completely separated, significantly improving the accuracy and convenience of optical path adjustment. Attached Figure Description

Detailed Implementation

[0032] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0033] The following is for reference. Figures 1-7 This application provides a two-dimensional angle-adjustable lens mount device, including a base 1, a transition plate 2, a lens mounting plate 3, a first angle actuator 4, and a second angle actuator 5.

[0034] The transition plate 2 includes a plate body 23 and a first rotating shaft 22 arranged in the horizontal direction. The first rotating shaft 22 is connected to the base 1 through a first shaft hole mating structure.

[0035] The lens mounting plate 3 includes a second rotating shaft 32 arranged in the vertical direction, and the second rotating shaft 32 is connected to the transition plate 2 through a second shaft hole fitting structure;

[0036] The first angle actuator can drive the transition plate 2 to rotate relative to the base 1 around the first rotating shaft 22.

[0037] The second angle actuator 5 can drive the lens mounting plate 3 to rotate relative to the transition plate 2 around the second rotating shaft 32.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the base 1 has a first groove 11 arranged horizontally, and the first rotating shaft 22 is rotatably engaged within the first groove 11, thereby changing the included angle between the transition plate 2 and the base 1, that is, causing the pitch angle of the lens mounting plate 3 to change. In some specific embodiments, the first groove 11 of the base 1 is a C-shaped groove with an opening arranged towards the transition plate 2, and the first rotating shaft 22 is disposed at the bottom end of the transition plate 2 and rotatably engaged with the C-shaped groove.

[0039] See Figure 2 and Figure 3 In this embodiment, the first shaft-hole mating structure includes a first threaded hole 16 disposed on the sidewall of the first groove 11 and a first setter (not shown in the figure) threadedly engaged with the first threaded hole 16. In some embodiments, multiple sets of first shaft-hole mating structures may be distributed equidistantly or unequally along the horizontal direction on the sidewall of the first groove 11. The end of the first setter abuts against the sidewall of the first rotating shaft 22 and generates a radial force on the first rotating shaft 22. Under the constraint of this radial force, the plate body 23 of the transition plate 2 can only rotate horizontally relative to the base 1 around the first rotating shaft 22, and will not translate. It can be understood that through the first shaft-hole mating structure between the transition plate 2 and the base 1, the transition plate 2 and the lens mounting plate 3 can rotate integrally around the first rotating shaft 22 between the transition plate 2 and the base 1 in the pitch direction, changing the angle between the plane of the transition plate 2 and the lens mounting plate 3 and the base 1, thereby realizing the angle adjustment of the lens in the pitch direction. In one specific implementation, the rotation angle of the plate body 23 of the transition plate 2 is ±3°. This rotation angle refers to the angle between the plane where the transition plate 2 is located and the horizontal plane, which increases or decreases by 0-3° from the initial position.

[0040] In some specific embodiments, the base 1 includes a base plate 13 and a fixing plate 12. The base plate 13 is arranged along a horizontal plane and can be fixed to the base by a bolt structure. The fixing plate 12 is perpendicular to the base plate 13, is L-shaped, and is arranged adjacent to the transition plate 2.

[0041] In some specific embodiments, the base 1 includes a first fixing part 14, one end of which is fixed to the base 1 and the other end extends to the side wall of the transition plate 2, and is provided with a first fixing hole 15, through which the base 1 and the transition plate 2 can be fixed by bolts.

[0042] In some specific implementations, a first mounting hole 16 is provided on one side of the fixing plate 12.

[0043] See Figure 4 and Figure 5 In this embodiment, the transition plate 2 includes a rotating portion 21 perpendicular to the plate body 23, and the rotating portion 21 includes a first rotating shaft 22 disposed at its end. In a specific embodiment, the transition plate 2 is L-shaped. In a specific embodiment, the plate body 23 and the rotating portion 21 of the transition plate 2 are integrally formed.

[0044] In this embodiment, the transition plate 2 further includes a side plate 25, which has a second groove 26 arranged vertically. The second rotating shaft 32 is rotatably engaged within the second groove 26, allowing it to rotate within the groove and thus change the angle between the transition plate 2 and the lens mounting plate 3, thereby changing the horizontal angle of the lens mounting plate 3. In some specific embodiments, the second groove 26 is a C-shaped groove with an opening facing the lens mounting plate 3, and the second rotating shaft 32 is located on one side of the lens mounting plate 3 and rotatably engages with the C-shaped groove.

[0045] In this embodiment, the second shaft hole mating structure includes a second threaded hole 27 disposed on the sidewall of the second groove 26 and a second setter (not shown in the figure) threadedly engaged with the second threaded hole 27. In some embodiments, multiple sets of second shaft hole mating structures may be distributed equidistantly or unequally along the vertical direction on the sidewall of the second groove 26. The end of the second setter abuts against the sidewall of the second rotating shaft 32 and generates a radial force on the second rotating shaft 32. Under the constraint of this radial force, the lens fixing plate 12 can rotate vertically relative to the transition plate 2 about the second rotating shaft 32 without translation. It can be understood that the lens mounting plate 3 can rotate horizontally about the second rotating shaft 32 between it and the transition plate 2, thereby changing the included angle between the lens mounting plate 3 and the transition plate 2, and thus achieving the angle adjustment of the lens in the horizontal direction. In a specific embodiment, the rotation angle of the lens fixing plate 12 is ±3°, which means that with the lens fixing plate 12 and the transition plate 2 parallel as the initial position, the included angle between the lens fixing plate 12 and the transition plate 2 increases or decreases by 0-3°.

[0046] See Figure 6 In this embodiment, a lens mounting position 31 is provided on the lens mounting plate 3, and an optical lens is mounted on the lens mounting position 31. Through holes are also provided on the plate body 23 of the transition plate 2 and the plate body 23 of the fixing plate 12 at the positions corresponding to the lens mounting position 31. The size of the through holes is adapted to the size of the lens to allow light to pass through.

[0047] In this embodiment, the lens mounting plate 3 further includes a second fixing part 33. One end of the second fixing part 33 is fixed to the lens mounting plate 3, and the other end extends to the upper wall of the transition plate 2. It is provided with a second fixing hole 35, through which the lens mounting plate 3 and the transition plate 2 can be fixed by bolts.

[0048] In this embodiment, as Figure 7As shown, the first angle actuator 4 and the second angle actuator 5 are angle adjustment assemblies with the same structure. The angle adjustment assembly includes a main body 40, a fixed pin 41, a movable pin 42, and an adjusting screw 43. One end of the adjusting screw 43 abuts against the movable pin 42 and can apply a radial force to the movable pin 42 to drive the movable pin 42 to slide on a side wall of the main body 40, thereby changing the relative position of the fixed pin 41 and the movable pin 42.

[0049] See Figure 1-Figure 4 , Figure 7 In this embodiment, a third mounting hole 29 is provided on one side of the transition plate 2, corresponding to the position of the first mounting hole 16 on the fixed plate 12. One end of the first angle actuator 4 is installed in the first mounting hole 16, and the other end is installed in the third mounting hole 29. By adjusting the first angle actuator 4, the distance between the transition plate 2 and the fixed plate 12 is changed, causing the transition plate 2 and the lens mounting plate 3 to move together as a whole, generating a rotational motion relative to the base 1. This causes the transition plate 2 to rotate along its connecting axis with the base 1 (i.e., the first rotating shaft 22), thereby realizing the angle adjustment in the pitch direction. In a specific embodiment, the fixed pin 41 and the movable pin 42 of the first angle actuator 4 are respectively installed in the first mounting hole 16 and the third mounting hole 29. By adjusting the adjusting screw 43 of the first angle actuator 4, the movable pin 42 is moved, thereby changing the pitch angle between the fixed plate 12 and the transition plate 2. In some embodiments, the first mounting hole 16 and the third mounting hole 29 are respectively disposed at an end away from the first rotating shaft 22 and the first groove 11, such as the upper part of the transition plate 2 and the fixing plate 12.

[0050] See Figures 4-7In this embodiment, a second mounting hole 28 is provided on one side of the transition plate 2, and a fourth mounting hole 36 is provided on the lens mounting plate 3 corresponding to the second mounting hole 28. One end of the second angle actuator 5 is installed in the second mounting hole 28, and the other end is installed in the fourth mounting hole 36. By adjusting the second angle actuator 5, the transition plate 2 is fixed to the base 1, which can drive the lens mounting plate 3 to rotate relative to the transition plate 2, thereby causing the lens to rotate about the connecting shaft (i.e., the second rotating shaft 32) between the transition plate 2 and the lens mounting plate 3, thereby realizing the horizontal angle adjustment. In a specific embodiment, the fixed pin 41 and the movable pin 42 of the second angle actuator 5 are respectively installed in the second mounting hole 28 and the fourth mounting hole 36. By adjusting the adjusting screw 43 of the second angle actuator 5, the movable pin 42 is moved, thereby changing the horizontal angle between the lens mounting plate 3 and the transition plate 2. In some embodiments, the second mounting hole 28 and the fourth mounting hole 36 are respectively located on the side away from the second rotating shaft 32 and the second groove 26. Therefore, the horizontal and vertical rotation of the lens can be adjusted with simple operation, and the two-dimensional angle adjustment is completely separated, which can significantly improve the accuracy and convenience of optical path adjustment.

[0051] In some embodiments, the first angle actuator 4 and the second angle actuator 5 are detachable and can be reused for angle adjustment of multiple devices.
