[0002] A reflector is an optical element that works using the law of reflection. During the optical path adjustment process of the laser, a reflector is required to reflect the incident light into a specific optical path.

[0003] At present, the reflector is fixed in the laser by a reflector adjustment frame. Based on the springs on the reflector adjustment frame, the angle of the reflected light is continuously adjusted in two dimensions, and then the reflector is fixed by the fixing parts. With the increase of usage time, the elasticity of the spring weakens, the reflector shifts, the angle of the reflected light changes, and the optical path changes. Because the stability of the laser light is positively correlated with the stability of the optical path, it is necessary to readjust the optical path regularly to maintain stability. For complex optical paths, the adjustment of the reflector involves the adjustment of other optical components behind the reflector, which increases the adjustment workload and has low adjustment efficiency.

[0065] In this embodiment, the angle between the support surface of the cylindrical segment 211 for supporting the reflector 400 and the cross section of the through hole 2211 is 1°-2°.

[0066] In this embodiment, an angle is set between the side surface of the cylindrical section 211 for mounting the reflector 400 and the cross section of the through hole 2211. On the one hand, it is used to compensate for the error generated during the processing of the reflector 400 and reduce the error in the direction of the reflected light. On the other hand, by rotating the rotating part 210, the reflector 400 is driven to rotate, and the reflected light is caused to rotate around the incident light, which is beneficial for the reflected light to enter a specific optical path.

[0067] In this embodiment, the lifting seat 221 drives the rotating member 210 to lift, the rotating support seat 222 drives the rotating member 210 to rotate, and the translation base 230 drives the rotating member 210 to translate, thereby realizing the lifting adjustment, rotation adjustment and translation adjustment of the reflector 400, which is conducive to making the incident light coincide with the center of the reflector 400.

[0068] In this embodiment, the rotating member 210, the lifting and rotating assembly 220 and the translation base 230 are pushed to move by the top screw 120 to achieve fine adjustment, which not only improves the adjustment efficiency but also improves the adjustment accuracy.

[0069] In the present invention, the connections between the components in the movable assembly 200 are all screw connections, so that the position of the reflector 400 remains stable for a long time.

[0070] Furthermore, the reflector 400 is mounted on the rotating member 210 and driven to rotate by the rotating member 210 to control the direction of the reflected light.

There are multiple first arc-shaped holes 2122, and the multiple first arc-shaped holes 2122 are evenly distributed circumferentially.

[0075] Furthermore, the fixed adjustment structure of the reflector of this embodiment further includes a pressing sheet 500, such as Figure 7 As shown, the reflector 400 is limited in the mounting hole by the pressing plate 500.

[0080] In this embodiment, the fixing block 110 is connected to the bottom plate 300. Figure 1 As shown, the top screw 120 pushes the translation base 230 to move, thereby completing fine adjustment of the translation of the translation base 230.

[0081] Furthermore, in order to expand the use range of the fine adjustment assembly 100, the fine adjustment assembly 100 also includes a ball joint assembly 130, such as Fig.12 and Fig.13 As shown; the fixed block 110 is connected to the translation base 230 and / or the base plate 300 through the ball joint assembly 130, and the fixed block 110 is driven to rotate through the ball joint assembly 130, thereby making the top screw 120 have a larger range of use.

[0082] In this embodiment, the ball joint assembly 130 includes a ball head rod having a ball head and a ball seat rod having a ball seat, and the ball head matches the ball seat. Fig.13 shown.

The position adjustment assembly 140 includes a base 141, a connecting rod 142 and a moving seat 143 which are connected in sequence.

[0085] In this embodiment, the connection modes of the position adjustment component 140, the ball joint component 130, and the fixing block 110 are flexible and varied, including the following two types:

[0086] In the first connection form, the position adjustment component 140, the ball joint component 130, and the fixing block 110 are connected in sequence, such as Fig.12 As shown; the base 141 is connected to the translation base 230 and / or the bottom plate 300, one end of the ball joint assembly 130 is connected to the movable seat 143, and the other end is connected to the fixed block 110.

[0087] The second connection form is that the ball joint assembly 130, the position adjustment assembly 140, and the fixed block 110 are connected in sequence; one end of the ball joint assembly 130 is connected to the translation base 230 and / or the base plate 300, and the other end is connected to the base 141; the movable seat 143 is connected to the fixed block 110.

Figure 5 As shown, a linear reciprocating motion is performed between the upper end and the lower end of the supporting side wall 2222 .

[0089] Considering the stability of the rotation path of the rotation support seat 222 and the controllability of the fine adjustment process, the rotation support seat 222 also includes a second arc-shaped hole 2223 and a second screw connection member 2224, such as Figure 6 As shown; the second screw member 2224 passes through the second arc-shaped hole 2223 and then the translation base 230 cooperates and connects, so that the rotating support seat 222 rotates along the second arc-shaped hole 2223, which is conducive to the fine adjustment of the rotating support seat 222.

[0090] Furthermore, in order to ensure the stability of the lifting and lowering adjustment of the lifting stand 221, the movable assembly 200 further includes a guide limit unit 240, such as Figure 5 As shown; the lifting seat 221 is connected to the rotating support seat 222 through the guide limit unit 240.
