Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to represent selected embodiments of this application.

[0034] In existing technologies, the reflection adjustment structures in commercially available laser processing equipment all rely on an adjusting plunger acting directly on the surface of a lens to apply pressure and cause an angular shift, thus ensuring the light path propagates in the desired direction. However, the tip of the adjusting plunger is prone to breaking the lens. Furthermore, in existing technologies, the reflecting lens and the reflector mount are separate; typically, replacing the lens alters the light path's direction, necessitating readjustment of the lens's offset angle.
[0035] In view of this, this application provides a laser reflection adjustment mechanism, such as... Figures 1-6As shown, the system includes: a support cover plate 10, an adjustment component 20, and a mounting base 30. The adjustment component 20 is located between the support cover plate 10 and the mounting base 30, and the support cover plate 10 is connected to the mounting base 30 for abutting the adjustment component 20 against the mounting base 30. For example, one side of the adjustment component 20 is embedded in the mounting base 30, and the other side of the adjustment component 20 is fixedly connected to the support cover plate 10 by a tension spring 28. Then, the support cover plate 10 and the mounting base 30 are fixedly connected by screws. In this way, the adjustment component 20 is held in place in the mounting base 30 by the support cover plate 10, avoiding the need for parts to be installed between the adjustment component 20 and the mounting base 30, and facilitating changes in the angle of the adjustment component 20.
[0036] The adjustment assembly 20 includes a reflective lens 21, a reflective lens mount 22, a lens pressure plate 23, and an adjustment component 24. The reflective lens 21 is installed in the lens pressure plate 23. For example, the shape of the lens pressure plate 23 is adapted to the shape of the reflective lens 21, and a mounting groove is provided in the lens pressure plate 23. The reflective lens 21 is embedded in the mounting groove, thus achieving the installation of the reflective lens 21 in the lens pressure plate 23. The reflective lens mount 22 covers the reflective lens 21 and is connected to the lens pressure plate 23. The side of the reflective lens mount 22 away from the reflective lens 21 is fixedly connected to the support cover plate 10. In this application, the reflective lens 21, the lens pressure plate 23, and the reflective lens mount 22 are connected to form a first integral unit. Then, the first integral unit is connected to the support cover plate 10 to form a second integral unit. Finally, the second integral unit is connected to the mounting base 30 to form a laser reflection adjustment mechanism.
[0037] The adjusting member 24 is preferably an adjusting plunger. One end of the adjusting member 24 is located in the supporting cover plate 10, and the other end of the adjusting member 24 passes through the supporting cover plate 10 and abuts against the surface of the reflector seat 22. The adjusting member 24 changes the reflection angle of the reflector 21 by adjusting the tilt angle of the reflector seat 22. Specifically, a tool can be used to apply force to the adjusting member 24 to press it against the reflector seat 22, adjusting the angle of the reflector seat 22 relative to the supporting cover plate 10 to a preset position. Since the reflector 21, the lens pressure plate 23, and the reflector seat 22 are integrally connected, the lens pressure plate 23 is also simultaneously adjusted to the preset position, thereby adjusting the reflection angle of the reflector 21 and achieving the preset direction of laser transmission.
[0038] Therefore, this application provides a laser reflection adjustment mechanism. By placing a reflector mount 22 on the reflector lens 21 and connecting it to the lens pressure plate 23, and fixing the side of the reflector mount 22 away from the reflector lens 21 to the support cover plate 10, the reflector lens 21, lens pressure plate 23, reflector mount 22, and support cover plate 10 become a whole. When replacing the reflector lens 21, only the lens pressure plate 23 needs to be removed, and the reflector mount 22 remains in the preset position. After the reflector lens 21 is installed, the angle relative to the support cover plate 10 will not change, and there is no need to readjust the optical path transmission direction. At the same time, when adjusting the optical path, the adjustment member 24 of this application abuts against the reflector mount 22, and the force is applied to the surface of the reflector mount 22, avoiding the risk of directly crushing the reflector lens.
[0039] According to some alternative embodiments, a first gasket 25 is provided on the side of the reflector mount 22 away from the reflector lens 21, that is, a first gasket 25 is provided on the side of the reflector mount 22 near the support cover plate 10. The first gasket 25 is fixedly installed on the reflector mount 22, and the end of the adjusting member 24 acts on the first gasket 25.
[0040] In the above scheme, the end of the adjusting member 24 abuts against the first shim 25, causing the reflector mount 22 to have an angular deviation, which in turn drives the reflector 21 to adjust its angle. The force of the adjusting member 24 acts directly on the reflector mount 22, avoiding the risk of directly crushing the reflector.
[0041] According to some optional embodiments, the first gasket 25 includes a first sub-gasket 251 and a second sub-gasket 252. The first sub-gasket 251 is provided with a first V-groove 2511, which extends and penetrates along the axis L1 of the first sub-gasket 251. The second sub-gasket 252 is provided with a second V-groove 2521, which extends and penetrates along the axis L2 of the second sub-gasket 252. The axis L1 of the first V-groove 2511 is perpendicular to the axis L2 of the second V-groove 2521.
[0042] In the above scheme, the number of adjusting members 24 corresponds to the number of first shims 25. The ends of the adjusting members 24 are inserted into the corresponding first V-grooves 2511 and second V-grooves 2521, causing the reflector 21 to undergo angular displacement, thereby adjusting the laser transmission direction. This avoids the situation where the reflector 21 is broken, and also avoids the adjusting members 24 slipping on the reflector base 22, which could damage the surface of the reflector base 22. The first V-grooves 2511 and second V-grooves 2521 are arranged perpendicularly to each other on the reflector base 22, which can effectively achieve positioning in the horizontal plane.
[0043] According to some alternative embodiments, the first sub-shield 251 and the second sub-shield 252 are diagonally arranged on the reflector mount 22. For example, the first sub-shield 251 and the second sub-shield 252 can be in a square diagonal form, so that when the adjusting member 24 acts on the first sub-shield 251 and the second sub-shield 252 respectively, the force can cause an angular change in the reflector 21, thereby changing the direction of light transmission.
[0044] According to some alternative embodiments, the reflector mount 22 is further provided with a second gasket 26 and a support member 27, one end of the support member 27 passing through the support cover plate 10 and abutting against the second gasket 26.
[0045] In the above scheme, preferably, the second gasket 26 is a conical gasket with a conical groove. The second gasket 26 and the first gasket 25 are located on the same plane. The support member 27 is a ball-headed post, with one end abutting against the second gasket 26 and the other end fixedly connected to the support cover plate 10. When adjusting the angle of the reflector 21, the end of the support member 27 acts in the conical groove of the second gasket 26, providing support and positioning and supporting the angle change of the reflector base 22. Then, it acts on the adjusting member 24 to adjust the angle of the reflector base 22 relative to the abutment point of the support member 27 and the second gasket 26.
[0046] According to some alternative embodiments, a tension spring 28 is also provided on the reflector mount 22, and the reflector mount 22 is connected to the support cover plate 10 via the tension spring 28.
[0047] In the above scheme, the reflector mount 22 is detachably connected to the support cover plate 10 by the tension spring 28. At the same time, sufficient space is reserved for the angle adjustment of the reflector mount 22 relative to the support cover plate 10. Moreover, it is ensured that when the reflector 21 is replaced, the reflector mount 22 can maintain the same angle relative to the support cover plate 10. This ensures that the angle of the reflector 21 relative to the support cover plate 10 does not change after the reflector 21 is installed, and there is no need to readjust the optical path transmission direction.
[0048] According to some alternative embodiments, the tension spring 28 includes a first tension spring 281, a second tension spring 282, and a third tension spring 283. The first tension spring 281 and the second tension spring 282 are distributed on both sides of the support member 27, and the third tension spring 283 is arranged diagonally opposite to the support member 27.
[0049] In the above scheme, preferably, the third tension spring 283 is fixedly installed at the diagonal of the square of the support member 27. This layout makes the tension near the support member 27 greater than the tension near the adjusting member 24, thus creating a tension difference. When the two adjusting members 24 are adjusted, they can effectively change the angle of the reflecting mirror 21, thereby changing the optical path transmission.
[0050] According to some alternative embodiments, a dust cap 29 is also provided on the support cover plate 10, and the dust cap 29 covers the adjustment member 24.
[0051] In the above scheme, one end of the adjusting component 24 is fixed to the supporting cover plate 10, and the dust cap 29 is correspondingly fixed on the supporting cover plate 10 and covers the adjusting component 24. After the beam direction adjustment is completed, the corresponding dust cap 29 is screwed on to prevent dust from entering the interior of the reflection adjustment mechanism and contaminating the optical path, thus achieving a sealing effect.
[0052] According to some alternative embodiments, the mounting base 30 is provided with a receiving groove 31, and the adjusting component 20 is partially embedded in the receiving groove 31 and the other part is embedded in the reflector base 22, which reduces the gap between the mounting base 30 and the reflector base 22, so that the two can be tightly connected, and at the same time avoids the pollution caused by the exposure of the optical path.
[0053] According to some optional embodiments, the reflector mount 22 and the lens plate 23 are connected by screws 40, so that the reflector 21, the reflector mount 22, and the lens plate 23 form a whole. When replacing the reflector 21, only the screws 40 need to be removed. The angle of the reflector 21 relative to the support cover 10 does not change. After installation, there is no need to readjust the optical path transmission direction.
[0054] Preferably, in this application, four screws are used to detachably connect the reflector mount 22 to the lens pressure plate 23.
