Description

Technical Field

[0001] This invention relates to the field of optomechanical assembly and adjustment, and in particular to a Dowell prism rotation coaxial adjustment device and adjustment method. Background Technology

[0002] A Dove prism is a type of image rotator commonly used in rotating optical engine systems. In these systems, the Dove prism and the rotating component must be coaxial to ensure that the reflected light is emitted as required. However, existing Dove prism adjustment devices are prone to damage because the prism is relatively fragile. Furthermore, the adjustment process is complex and difficult to quickly and effectively adjust to the set requirements.

[0003] Therefore, those skilled in the art are dedicated to developing a rotary coaxial adjustment device and method for Daowei prisms, which not only facilitates the adjustment of Daowei prisms to the set requirements, but also makes the adjustment simple and fast. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rotary coaxial adjustment device and adjustment method for Daowei prisms, which not only facilitates the adjustment of Daowei prisms to the set requirements, but also makes the adjustment simple and fast.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a Daowei prism rotation coaxial adjustment device, comprising a prism mounting bracket, an adjustment panel, a fixed mounting plate and a rotation motor;

[0006] The prism mounting bracket is provided with a locking cavity for locking the Dowell prism, and the upper end of the prism mounting bracket is connected to the adjustment panel. The adjustment panel has a light outlet hole that is directly opposite the locking cavity and is used for light to be emitted.

[0007] The adjustment panel is provided with a plurality of evenly distributed first through holes and first adjustment holes. The first connector passes through the first through hole and is connected to the inner ring of the rotary motor. The first adjustment component passes through the first adjustment hole and abuts against the upper end of the prism mounting bracket.

[0008] The fixed mounting plate is connected to the outer ring of the rotary motor, and the fixed mounting plate is also provided with a second adjustment hole, through which the second adjustment member passes and abuts against the rotary motor.

[0009] The beneficial effects of this invention are: after the prism mounting bracket secures and fixes the Daowei prism, the distance between the adjustment panel and the prism mounting bracket and the fixed mounting plate and the rotary motor can be adjusted to adjust the emitted light of the Daowei prism, so that the optical axis of the rotary motor and the optical axis of the emitted light are on the same straight line. This not only has a simple structure, but also makes debugging simple, further improving debugging efficiency.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the prism mounting bracket includes a prism tube, which is cylindrical, and the engaging cavity is located on the prism tube and is arranged along the length of the prism tube.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the prism tube is cylindrical, which reduces the centrifugal force of rotation and ensures that the Daowei prism rotates smoothly.

[0013] Furthermore, the prism tube is provided with a second through hole and a first abutting hole. The first abutting member passes through the first abutting hole and abuts against the Daowei prism. The second through hole is filled with ultraviolet adhesive for fixing the Daowei prism.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the Daowei prism is abutted in the locking cavity by the first abutting member, which further strengthens the fastening; the ultraviolet adhesive is used to fasten the Daowei prism, and at the same time, the ultraviolet adhesive is used to reduce vibration and reduce the vibration of the Daowei prism.

[0015] Furthermore, a connecting portion is provided on the upper part of the prism tube, and a first connecting hole is provided on the connecting portion;

[0016] The adjustment panel is provided with a third through hole, and the second connector passes through the third through hole and connects to the first connecting hole.

[0017] The advantage of adopting the above-mentioned further solution is that the connecting part facilitates the connection between the prism tube and the adjustment panel, and at the same time facilitates the adjustment of the distance between the adjustment panel and the prism mounting bracket.

[0018] Furthermore, the fixed mounting plate is provided with a panel engaging cavity for engaging the adjustment panel.

[0019] The advantages of adopting the above-mentioned further solution are that the panel locking cavity fixes the adjustment panel, the structure is compact, and the space utilization rate is improved.

[0020] Furthermore, the fixed mounting plate and the rotary motor are connected by a motor adapter plate, and the third connector passes through the fixed mounting plate and the motor adapter plate and is connected to the outer ring of the rotary motor.

[0021] The advantage of adopting the above-mentioned further solution is that the motor mounting plate facilitates the connection between the fixed mounting plate and the rotary motor, and also facilitates the adjustment of the distance between the fixed mounting plate and the rotary motor.

[0022] Furthermore, a connecting plate is installed on the side wall of the fixed mounting plate, the connecting plate being perpendicularly connected to the fixed mounting plate, and the connecting plate having multiple mounting holes.

[0023] The advantage of adopting the above-mentioned further solution is that the connecting plate facilitates the installation of the debugging device in a designated location.

[0024] A method for adjusting the rotational coaxiality of a Dove prism, comprising the Dove prism rotational coaxiality adjustment device as described above, includes the following steps:

[0025] 1) Install the Daowei prism rotation coaxial adjustment device in the designated position so that its light enters from the bottom of the rotation motor, exits from the light outlet, and is captured by the light sensor opposite to the light outlet;

[0026] 2) When the first connecting member is adjusted so that its adjustment panel is close to the rotary motor, the first adjusting member is simultaneously adjusted so that its first adjusting member abuts against the prism mounting bracket, so that when the rotary motor rotates 180°, the emitted light returns to the starting position.

[0027] 3) When the third connector is adjusted so that the fixed mounting plate and the rotary motor are close to each other, the second adjusting member is adjusted so that the second adjusting member and the rotary motor abut against each other, so that when the rotary motor rotates, the emitted light rotates around the emitted light axis, thereby making the optical axis of the rotary motor and the optical axis of the emitted light on the same straight line.

[0028] The advantage of adopting the above-mentioned further solution is that the adjustment of the entire Daowei prism is completed by adjusting the first connector, the first adjusting component, the third connector, and the second adjusting component, and the adjustment effect is more intuitive and more regular.

[0035] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0036] In the description of this invention, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "inner," "outer," "circumferential," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a Dowell prism rotation coaxial adjustment device includes a prism mounting bracket 200, an adjustment panel 300, a fixed mounting plate 500, and a rotary motor 400. The prism mounting bracket 200 is provided with a locking cavity 211 for locking the Dowell prism 100. The adjustment panel 300 is connected to the upper end of the prism mounting bracket 200. The adjustment panel 300 has a light outlet 310 facing the locking cavity 211 and for light to be emitted. The adjustment panel 300 is provided with a plurality of uniformly spaced... The first through hole 301 and the first adjustment hole 302 are distributed. The first connecting piece 303 passes through the first through hole 301 and is connected to the inner ring of the rotary motor 400. The first adjustment piece 304 passes through the first adjustment hole 302 and abuts against the upper end of the prism mounting bracket 200. The fixed mounting plate 500 is connected to the outer ring of the rotary motor 400, and the fixed mounting plate 500 is also provided with a second adjustment hole 503. The second adjustment piece 501 passes through the second adjustment hole 503 and abuts against the rotary motor 400.

[0040] In this invention, after the prism mounting bracket 200 secures and fixes the Daowei prism 100, the distance between the adjustment panel 300 and the prism mounting bracket 200, and between the fixed mounting plate 500 and the rotary motor 400, is adjusted to adjust the emitted light beam of the Daowei prism 100, so that the optical axis of the rotary motor 400 and the optical axis of the emitted light beam are on the same straight line. This not only has a simple structure, but also makes debugging simple, further improving debugging efficiency.

[0041] like Figure 2 , Figure 3 As shown, in some embodiments, the prism mounting bracket 200 includes a prism tube 210, the length of which is greater than the length of the Daowei prism 100. The prism tube 210 is cylindrical to reduce the centrifugal force generated by the prism tube 210 during rotation. The locking cavity 211 is located on the prism tube 210 and is arranged along the length direction of the prism tube 210. The reflecting surface of the Daowei prism 100 should be consistent with the opening direction of the locking cavity 211.

[0042] The prism tube 210 is provided with a second through hole 212 and a first abutting hole 213. The first abutting member passes through the first abutting hole 213 and abuts against the Daowei prism 100. The second through hole 212 is filled with UV adhesive for fixing the Daowei prism 100. The first abutting hole 213 can be a threaded hole, and the first abutting member can be a rubber-tipped threaded screw that mates with the threaded hole. The rubber-tipped threaded screw prevents hard contact with the Daowei prism 100, reducing damage to the Daowei prism 100. The UV adhesive not only further secures the Daowei prism 100, but also effectively reduces the vibration of the Daowei prism 100, extending its service life.

[0043] A connecting portion 220 is provided on the upper part of the prism tube 210. The connecting portion 220 is also cylindrical, and its diameter is larger than that of the prism tube 210. A recess for light to pass through is provided on the connecting portion 220. A first connecting hole, which is a threaded hole, is provided on the upper end of the connecting portion 220. A third through hole 305 is provided on the adjustment panel 300. A second connecting piece 306 passes through the third through hole 305 and connects to the first connecting hole, thereby connecting and fixing the connecting portion 220 to the adjustment panel 300.

[0044] In this embodiment, the fixed mounting plate 500 is provided with a panel engaging cavity 520 for engaging the adjustment panel 300. The panel engaging cavity 520 is clearance-fitted with the fixed mounting plate 500, and a step is provided inside the panel engaging cavity 520 to limit the adjustment panel 300. A connecting plate 510 is installed on the side wall of the fixed mounting plate 500. The connecting plate 510 is perpendicularly connected to the fixed mounting plate 500. The connecting plate 510 is provided with multiple mounting holes 511, through which the adjustment device can be installed in a designated position.

[0045] In some embodiments, the fixed mounting plate 500 and the rotary motor 400 are connected by a motor adapter plate 600. The third connector 502 passes through the fixed mounting plate 500 and the motor adapter plate 600 and is connected to the outer ring of the rotary motor 400. The outer ring of the rotary motor 400 is provided with a connection hole that mates with the third connector 502.

[0046] The present invention also provides a method for adjusting the rotational coaxiality of a Dove prism, including the Dove prism rotational coaxiality adjustment device as described above, comprising the following steps:

[0047] 1) Install the Daowei prism rotation coaxial adjustment device in the designated position so that its light enters from the bottom of the rotary motor 400, exits from the light outlet 310, and is captured by the light sensor opposite to the light outlet 310. For ease of adjustment, a laser can be used to adjust the light. The light sensor is used to detect changes in the position of the emitted light, thereby facilitating subsequent adjustments.

[0048] 2) When adjusting the first connecting member 303 so that the adjustment panel 300 and the rotary motor 400 are close to each other, simultaneously adjust the first adjusting member 304 so that it abuts against the prism mounting bracket 200. This causes the emitted light to return to the starting position when the rotary motor 400 rotates 180°. During the adjustment process, while adjusting the first connecting member 303, adjust the first adjusting member 304 to tighten them together to determine the distance. To facilitate quick adjustment to the appropriate position, the first connecting member 303 and the first adjusting member 304 are evenly distributed at the four corners of the adjustment panel 300. After adjustment, the optical axis of the Daowei prism 100 is coaxial with the optical axis of the rotary motor 400.

[0049] 3) When adjusting the third connecting piece 502 so that the mounting plate 500 and the rotary motor 400 are close to each other, simultaneously adjust the second adjusting piece 501 so that it abuts against the rotary motor 400. This causes the emitted light beam to rotate around its axis as the rotary motor 400 rotates, thus aligning the optical axis of the rotary motor 400 with the optical axis of the emitted light beam. The adjustment methods for the third connecting piece 502 and the second adjusting piece 501 are the same as those for the first connecting piece 303 and the first adjusting piece 304. After adjustment, the optical axis of the rotary motor 400 is coaxial with the desired emitted light beam, thus completing the coaxial adjustment process of the Daowei prism 100.
