Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a laser shutter and a laser, which can enable incident beams entering the laser shutter to be switched to different coupling assemblies at different time, and output optical fibers connected with different coupling assemblies can be different, so that one laser can be applied to different fields. The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 1 to 3, fig. 1 is a first structural schematic diagram of a laser shutter according to an embodiment of the present disclosure, fig. 2 is a second structural schematic diagram of a laser shutter according to an embodiment of the present disclosure, and fig. 3 is a cross-sectional view taken along the direction N-N in fig. 2.

The present embodiment provides a laser shutter 100. Laser shutter 100 includes at least first housing 5, first reflecting mirror 4, and optical path switching unit 3.

The first housing 5 has a first accommodation space 51, a light entrance port, and a plurality of light exit ports (first light exit ports 53), which communicate with the first accommodation space 51, the plurality of first light exit ports 53. It is understood that the first housing 5 can protect other structures of the laser shutter 100 disposed therein, and has dust-proof and touch-proof effects. The first housing 5 may be designed to have a corresponding shape according to the optical path of the laser beam. The first housing 5 has at least one light inlet and a plurality of first light outlets 53, the axes of each first light outlet 53 are parallel or intersecting, the laser beam can be switched to different first light outlets 53 at different times, and the effect of time-sharing light emission is achieved.

The first reflector 4 is used for reflecting the incident light beam into a first reflected light beam, which enters the first accommodating space 51 from the light inlet. The first mirror 4 is used to reflect the incident light beam as a first reflected light beam. The incident beam intersects the angle of the first reflected beam. The optical path of the first reflected light beam passes through the optical path switching component 3, and can be reflected by the optical path switching component 3.

The optical path switching member 3 is disposed in the first accommodating space 51, and the optical path switching member 3 is configured to reflect the first reflected light beam as a second reflected light beam which exits the first accommodating space 51 from one of the first light exit ports 53. The second reflected beam intersects the angle of the first reflected beam. It can be understood that the optical path switching component 3 not only can reflect light, but also can emit light from one of the first light outlets 53 according to the adjustment of a commissioning worker. It can be understood that, a commissioning worker can adjust the optical path switching component 3 to make the laser beam exit from the different first light exit ports 53, so as to achieve the effect of time-sharing light exit.

In some embodiments, the laser shutter 100 further includes a second housing 7 and a first adjustment base 6, the second housing 7 has a second accommodating space 71, the second housing 7 is connected to the first housing 5, and the first accommodating space 51 communicates with the second accommodating space 71. The first adjusting base 6 is connected to the second housing 7, the first reflecting mirror 4 is disposed in the second accommodating space 71 and connected to the first adjusting base 6, and the first adjusting base 6 is used for adjusting the inclination angle of the first reflecting mirror 4.

The first adjusting base 6 comprises a first fixing seat and at least three first adjusting structures, the first reflecting mirror 4 is mounted on the first fixing seat through the first adjusting structures, and the first adjusting structures can move along the normal direction of the first reflecting mirror 4 to adjust the inclination angle of the first reflecting mirror 4.

Further, the first reflector 4 is provided with three positioning points a, B and C, and the connecting line of the three positioning points can be in a right triangle shape. Point a is fixed, and points B and C can both move back and forth along the normal direction of the first mirror 4, so that the first mirror 4 can deflect around the axis AB and the axis AC, respectively, to adjust the tilt angle of the first mirror 4.

In some embodiments, the laser shutter 100 further comprises a plurality of second adjustment bases 8, each second adjustment base 8 is connected to one second mirror 31, and the second adjustment base 8 is used for adjusting the inclination angle of the second mirror 31.

The second adjusting base 8 comprises a second fixed seat and at least three second adjusting structures, the second reflecting mirror 31 is mounted on the second fixed seat through the second adjusting structures, and the second adjusting structures can move along the normal direction of the second reflecting mirror 31 to adjust the inclination angle of the second reflecting mirror 31.

For example, the laser shutter 100 may be adjusted in such a way that the distance between the point a and the fixed base is fixed and the distance between the point B or the point C and the fixed base is adjusted when the tilt angle of the first reflecting mirror 4 is adjusted. Due to the existence of measurement errors, machining errors and installation errors, only the distance between the point B or the point C and the fixed seat is adjusted, so as to adjust the inclination angle of the first reflecting mirror 4, and further the first reflecting mirror 4 reflects the incident light to form a first reflected light, and finally each second reflecting mirror 31 can reflect the first reflected light. It is understood that the plurality of second reflectors 31 may not be positioned on the same horizontal line due to the assembling error, which results in that the light spot formed by the first reflected light on each second reflector 31 may be positioned at different positions of each second reflector 31 although each second reflector 31 is positioned at the optical path conducting position in turn. Therefore, it is only necessary to adjust the inclination of the first reflecting mirror 4 so that the first reflected light can be reflected by each second reflecting mirror 31.

Thereafter, the tilt angle of each second reflecting mirror 31 is adjusted. When the second reflecting mirror 31 is in the optical path conducting position, the inclination of the second reflecting mirror 31 is adjusted so that the second reflected light beam reflected by the second reflecting mirror 31 is parallel to or coincides with the axis of the corresponding first light outlet 53.

In some embodiments, please refer to fig. 4 to 6, fig. 4 is a third structural diagram of the laser shutter according to the embodiment of the present disclosure, fig. 5 is a fourth structural diagram of the laser shutter according to the embodiment of the present disclosure, and fig. 6 is a cross-sectional view taken along the direction M-M of fig. 5. Laser shutter 100 also includes a plurality of adjustment mechanisms 1 and a plurality of coupling assemblies 2. Each adjusting mechanism 1 is connected to the first housing 5. Each coupling unit 2 is connected to an adjusting mechanism 1. Wherein the adjustment mechanism 1 is used to adjust the relative position of the coupling component 2 and the first housing 5 such that the second reflected light beam passes through the optical path of the coupling component 2.

Each coupling assembly 2 comprises a focusing lens group and an output coupling joint, and the second reflected light beam corresponds to a focusing lens group and an output coupling joint. The second reflected light beam is focused by the focusing lens group and then coupled into an output optical fiber locked on the output coupling joint, thereby realizing different processing applications.

Wherein the second reflected light beam reflected by the optical path switching component 3 needs to be received by the input optical fiber arranged in the coupling component 2 to realize different processing applications. However, due to assembly errors between the optical path switching component 3 and the first light outlet 53 and the coupling component 2, the second reflected light beam reflected by the optical path switching component 3 may not enter the optical path channel of the coupling component 2 after exiting the first accommodating space 51, but may hit the sidewall of the optical path channel of the coupling component 2, and thus cannot be received by the input optical fiber, so the relative position of the coupling component 2 and the first housing 5 can be adjusted by the adjusting mechanism 1, so that the second reflected light beam can pass through the optical path channel of the coupling component 2 and then be received by the input optical fiber.

In some embodiments, the laser shutter 100 further comprises a beam chopping assembly 9, the beam chopping assembly 9 being disposed in the path of travel of the first reflected beam. The optical path switching member 3 is disposed between the first reflecting mirror 4 and the beam chopping member 9. It will be appreciated that the beam chopping component 9 is arranged to absorb the first reflected beam when the optical path switching component 3 is not reflecting the first reflected beam.

Wherein, the first housing 5 further has a second light outlet 54. The second light outlet 54 is communicated with the light inlet and the first accommodating space 51, and the light inlet and the second light outlet 54 are located on the same straight line. The beam stop assembly 9 may be disposed outside the first housing 5, and the first reflected light beam can pass through the second light outlet 54 and be absorbed by the beam stop assembly 9. Optionally, the beam chopping assembly 9 is connected to the housing.

In some embodiments, the optical path switching assembly 3 includes a plurality of second reflecting mirrors 31, each second reflecting mirror 31 is disposed on the optical path of the first reflected light beam, and each second reflecting mirror 31 corresponds to one first light outlet 53. The second mirror 31 can be in an optical path on position or an optical path off position. When the second reflecting mirror 31 is in the optical path conducting position, the second reflecting mirror 31 can reflect the first reflected light beam as a second reflected light beam; when the second mirror 31 is in the optical path cutoff position, the second mirror 31 is spaced from the first reflected light beam.

For example, if a plurality of second reflecting mirrors 31 are arranged along a straight line, and each second reflecting mirror 31 is to be disposed on the optical path of the first reflected light beam, the inclination of the first reflecting mirror 4 needs to be adjusted so that the first reflected light beam reflected by the first reflecting mirror 4 approximately coincides with the straight line, so as to ensure that each second reflecting mirror 31 is disposed on the optical path of the first reflected light beam.

Thereafter, the tilt angle of each second reflecting mirror 31 is adjusted. When the second reflecting mirror 31 is at the optical path conducting position, the inclination of the second reflecting mirror 31 is adjusted so that the second reflected light beam reflected by the second reflecting mirror 31 is parallel to or coincides with the axis of the corresponding first light outlet 53.

In some embodiments, the optical path switching assembly 3 includes a third reflecting mirror disposed on the optical path of the first reflected optical beam, and the third reflecting mirror is capable of moving to a plurality of reflecting positions, each corresponding to one of the first light outlets 53. When the third reflector is at one of the reflecting positions, the second reflected light beam exits the first accommodating space 51 from the corresponding first light outlet 53.

In some cases, the laser shutter 100 further includes a rotational drive mechanism coupled to the third mirror for driving the third mirror to rotate to one of the reflective positions. For example, the rotation driving mechanism drives the third reflecting mirror to rotate, and when an included angle between a normal of the third reflecting mirror and the first reflected light beam is 60 °, the third reflecting mirror corresponds to one first light outlet 53, that is, the second reflected light beam can be coaxial with the optical path channel of the first light outlet 53; when the angle between the normal of the third reflecting mirror and the first reflected light beam is 80 °, the first reflected light beam corresponds to another first light outlet 53, that is, the first reflected light beam can be coaxial with the optical path channel of this first light outlet 53.

In other instances of the present embodiment, the laser shutter 100 further includes a slide rail and a slider slidably coupled to the slide rail. The slide rail and the slider are arranged in the first receiving space 51, and the slider is connected to the third mirror so that the third mirror can slide to one of the reflecting positions.

Optionally, since the second reflected light beam has a certain cross-sectional area, if only a part of the second reflected light beam is received by the test optical fiber, the value on the power meter is the first value; if the second reflected beam is completely received by the test fiber, the value on the power meter is a second value; the first value is less than the second value. The relative position of the coupling assembly 2 and the first housing 5 is adjusted by the adjusting mechanism 1 until the current maximum value is displayed on the power meter. When the value displayed on the power meter is the current maximum value, it indicates that the second reflected light beam can be completely received by the test fiber.

The adjustment mechanism 1 comprises a first support 11, a second support 12 and an adjustment assembly 13. The first support 11 is provided with a first through hole 111, and the second support 12 is provided with a second through hole 121. The first through hole 111 communicates with the second through hole 121. The axis of the second through-hole 121 is parallel to the axis of the first through-hole 111. The first through hole 111 and the second through hole 121 may form an optical path channel together. The adjusting assembly 13 is connected to the first supporting member 11 and the second supporting member 12, and the adjusting assembly 13 is used for driving the second supporting member 12 to move along the radial direction of the first through hole 111.

In the step of adjusting the relative position of the coupling assembly 2 and the first housing 5 by the adjusting mechanism 1, the method for adjusting the laser shutter 100 includes adjusting the adjusting assembly 13 to drive the second support 12 to move along the radial direction of the first through hole 111.

Wherein, the first support 11 or the second support 12 can be used to connect with the coupling component 2.

In the embodiment of the present application, please refer to fig. 10, and fig. 10 is a schematic structural diagram of a coupling device according to the embodiment of the present application. The second support 12 is connected to the coupling assembly 2, and the adjusting assembly 13 adjusts the second support 12 to move along the radial direction of the first through hole 111, so that the collimated light beam is aligned with the optical path channel of the coupling assembly 2 of the second support 12, and the optical path deviation is avoided, thereby affecting the processing performance.

In some embodiments, the first through hole 111 of the first support 11 is coaxial with the collimated light beam, and the second through hole 121 of the second support 12 is coaxial with the optical path channel of the coupling component 2. That is, the user only needs to adjust the first through hole 111 of the first supporting member 11 to be coaxial with the second through hole 121 of the second supporting member 12, so that the collimated light beam can be aligned with the optical path channel of the coupling assembly 2, that is, in the same straight line, thereby avoiding the optical path deviation and improving the processing performance.

In other embodiments, the first through hole 111 of the first support 11 is not coaxial but parallel with the collimated light beam, or/and the second through hole 121 of the second support 12 is not coaxial but parallel with the optical path channel of the coupling assembly 2. In the embodiment of the present application, only during the assembly process, the axis of the first through hole 111 is parallel to the collimated light beam, and the axis of the second through hole 121 is parallel to the optical path channel of the coupling component 2, so as to meet the installation standard, that is, the first through hole 111 and the second through hole 121 only form the optical path channel, and a user can adjust the relative position of the collimated light beam and the optical path channel of the coupling component 2 by adjusting the relative position of the first support 11 and the second support 12, so as to center the collimated light beam and the optical path channel of the coupling component 2, thereby avoiding the optical path deviation, and improving the processability.

In some embodiments, the second supporting member 12 is at least partially disposed in the first through hole 111, and the adjusting component 13 is disposed through the first supporting member 11 and connected to the second supporting frame. Optionally, the first support 11 is provided with a mounting hole 113. The adjusting component 13 is disposed through the mounting hole 113 and abuts against a side surface of the second supporting member 12, so as to adjust the radial movement of the second supporting member 12 along the first through hole 111. It will be appreciated that the wall of the mounting hole 113 acts as a stop for the adjustment assembly 13, such that the adjustment assembly 13 adjusts the radial movement of the second support member 12 relative to the first through hole 111.

In some cases, the adjusting component 13 is connected to the second supporting component 12, and when the adjusting component 13 moves relative to the hole wall of the mounting hole 113, the adjusting component 13 can drive the second supporting component 12 to move relative to the first supporting component 11. Optionally, the adjusting assembly 13 passes through the mounting hole 113 of the first supporting member 11 and is screwed with the second supporting member 12, and the wall of the mounting hole 113 supports the adjusting assembly 13 and the second supporting member 12.

In other cases of the embodiments of the present application, the adjusting component 13 abuts against the second supporting component 12, and when the adjusting component 13 moves relative to the hole wall of the mounting hole 113, the adjusting component 13 can apply a force to the second supporting component 12 to move the second supporting component 12 radially relative to the first through hole 111.

Optionally, the second supporting member 12 is partially disposed in the first through hole 111, and an inner diameter of the first through hole 111 is larger than an outer diameter of a structure of the second supporting member 12 located in the first through hole 111. The first supporting member 11 further includes a mounting portion 112, the mounting portion 112 is connected to the hole wall of the first through hole 111, and the mounting portion 112 is used for supporting the second supporting member 12, so as to improve the reliability of the overall structure.

The adjustment mechanism 1 further comprises a spacer (denoted as first spacer 14), and the first spacer 14 may be arranged between the first support 11 and the mounting portion 112. Since the second support 12 moves radially relative to the first support 11, friction between the first support 11 and the second support 12 may cause abrasion or the like, which affects the adjustment accuracy. Therefore, the first gasket 14 is disposed between the first supporting member 11 and the mounting portion 112, so as to prevent the first supporting member 11 and the second supporting member 12 from being worn. During the process of moving the second supporting member 12 relative to the first gasket 14, even if the first gasket 14 is worn out to cause inaccurate adjustment, the first gasket 14 is replaced, thereby greatly reducing the cost.

The first gasket 14 may be made of teflon, which is also called teflon, teflon. The polytetrafluoroethylene has low friction coefficient and has lubricating effect.

In some embodiments, please refer to fig. 1, the adjusting assembly 13 includes a first adjusting member 131 and a second adjusting member 132, the first adjusting member 131 penetrates through the first supporting member 11 in the first direction and abuts against the second supporting member 12, and the second adjusting member 132 penetrates through the first supporting member 11 in the second direction and abuts against the second supporting member 12. The first direction intersects the second direction. Optionally, the first direction is perpendicular to the second direction.

In other cases, the adjustment mechanism 1 further comprises a second pad 15, the second pad 15 being arranged on a side of the second support 12 remote from the first pad 14.

It will be appreciated that the first adjustment member 131 can press the second support member 12 in a plane parallel to the radial plane of the first through hole 111, so that the second support member 12 moves in a first direction with respect to the first support member 11; the second adjusting member 132 can press the second supporting member 12, so that the second supporting member 12 moves in the second direction relative to the first supporting member 11, and thus the position of the second supporting member 12 relative to the first supporting member 11 can be adjusted in a plurality of angles, and the adjustment efficiency is improved.

With continued reference to fig. 8, the first adjustment element 131 includes a first adjustment sub-element 1311 and a second adjustment sub-element 1312, the first adjustment sub-element 1311 is screwed to the first support 11 in the first direction, the first adjustment sub-element 1311 is capable of abutting against the second support 12, the second adjustment sub-element 1312 is screwed to the second support 12 in the first direction, and the second adjustment sub-element 1312 is capable of abutting against the second support 12.

Correspondingly, the adjustment manner of the first adjusting member 131 in the first direction is as follows: when the first adjustment sub 1311 moves in the positive first direction, the second adjustment sub 1312 moves in the negative first direction; when the first adjustment assembly 13 moves in a negative direction of the first direction, the second adjustment subassembly 1312 moves in a positive direction of the first direction.

Referring to fig. 9 and 11, fig. 11 is a schematic structural diagram of a first adjusting sub-element according to an embodiment of the present disclosure. The first sub-adjustment portion includes a stud (referred to as a first stud 13111), a support plate (referred to as a first support plate 13112), and at least one first elastic member 13113 (referred to as a first elastic member 13113), the first stud 13111 is inserted into the first support member 11 in the first direction, the first support plate 13112 is connected to the first stud 13111, the at least one first elastic member 13113 is connected to the first support plate 13112, and the first elastic member 13113 is disposed in parallel to the first stud 13111, so that the elastic member can abut against the second support member 12 in the first direction. When the first elastic member 13113 is in the natural state, the distance between the first elastic member and the second support 12 is smaller than the distance between the stud and the second support 12. It will be appreciated that when the second support 12 is in contact with the stud, the first resilient member 13113 is in a compressed state, i.e. the first resilient member 13113 exerts a force on the second support 12.

The first support plate 13112 is disposed on the first stud 13111 in a penetrating manner, the first stud 13111 is provided with a first position-limiting portion 13114, and the first position-limiting portion 13114 is engaged with the first support plate 13112.

It will be appreciated that, in order to be able to accommodate coupling assemblies 2 of various sizes, the adjustment mechanism 1 is further provided with a connecting piece 16, which connecting piece 16 is arranged between the second support 12 and the coupling assembly 2. On the one hand, the first connection section 162 is disposed in the second through hole 121, the first connection section 162 being for fitting with the second support 12; on the other hand, the outer diameter of the second connecting section 163 is larger than that of the first connecting section 162, and the second connecting section 163 can be adapted to the size of the coupling component 2.

With reference to fig. 10, the present application further provides a coupling device 10, which includes the above-mentioned adjusting mechanism 1 and a coupling component 2, wherein the adjusting mechanism 1 is disposed at one end of the coupling component 2.

The present application also provides a laser shutter 100, the laser shutter 100 comprising a first housing 5, an optical path switching assembly 3 and the coupling device 10 described above. The first housing 5 includes a light inlet and a plurality of first light outlets 53. The optical path switching component 3 is disposed in the first housing 5, and the optical path switching component 3 can switch a light beam input from the light inlet to one of the first light outlets 53 for output. The side of the adjusting mechanism 1 remote from the coupling group is connected to the first housing 5. The adjusting mechanism 1 includes a first supporting member 11 and a second supporting member 12, the first supporting member 11 is connected to the first housing 5, and the second supporting member 12 is connected to the coupling device 10.

In some embodiments, the area of the optical path switching component 3 for reflecting the first reflected light beam is a reflection area, and an orthographic projection of the reflection area on the radial plane of the first light outlet 53 is located in the first light outlet 53. It can be understood that, after the first reflecting mirror 4 reflects the incident light beam into the first reflected light beam, the difficulty of the coincidence of the second reflected light beam and the axis of the optical path channel of the coupling component 2 is relatively high, so that the angle of the reflection area of the optical path switching component 3 often needs to be adjusted, so that the second reflected light beam reflected by the optical path switching component 3 is parallel to or coincides with the axis of the corresponding light outlet. Since the second reflected light beam may not coincide with the axis of the first light outlet 53, the diameter of the first light outlet 53 is large, so that the orthographic projection of the reflection region of the optical path switching assembly 3 on the radial plane of the first light outlet 53 is located in the first light outlet 53, thereby determining that the second reflected light beam can pass through the first light outlet 53; otherwise, the position of the optical path switching component 3 needs to be adjusted, so that the orthographic projection of the reflection area of the optical path switching component 3 on the radial plane of the first light outlet 53 is located in the first light outlet 53.

It can be understood that the diameter of the first light outlet 53 is increased, so that the debugging difficulty is reduced, and the debugging efficiency is improved.

The present embodiment also provides a laser, which includes the laser shutter 100 in the present embodiment, and a laser generator, whose laser output port is connected to the laser shutter 100, and is used for outputting the incident light beam. When the angle between the incident beam and the normal of the first reflecting mirror 4 is 45 degrees, the laser generator and the laser shutter 100 are arranged in parallel, so that the compact design of the laser is realized, and the miniaturization of the laser is realized.

The laser shutter 100 and the laser provided by the embodiment of the present application, the laser shutter 100 has a first housing 5, a first reflecting mirror 4, an optical path switching assembly 3, a plurality of adjusting mechanisms 1, and a plurality of coupling assemblies 2. Since the optical path switching element 3 reflects the first reflected light beam as the second reflected light beam, the second reflected light beam exits from one of the light exit ports and enters the corresponding coupling element 2. Therefore, the laser shutter 100 can switch the incident beam entering the laser shutter 100 to different coupling elements 2 at different times, thereby realizing that one laser can be applied in different fields.
