[0046] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0047] Example 1, in conjunction with Appendix Figure 1-5 An assembly and adjustment device for bonding an internal reflection prism to a detector, comprising:

[0048] Packing box 1;

[0049] A two-axis rotary table 2 is located on the bottom surface of the assembly box 1. It has a rotary table 21, a first rotating part 22 that can drive the rotary table 21 to rotate along the X-axis, and a second rotating part 23 that can drive the rotary table 21 to rotate along the Y-axis.

[0050] Combined with appendix Figure 2 Furthermore, the two-axis turntable 2 includes an L-shaped base 24 on the bottom surface of the mounting box 1. The upper end of the vertical section of the L-shaped base 24 is provided with a first driving device 25 for driving the first rotating part 22 to rotate and a first angle detector 26 for detecting the rotation angle of the first rotating part 22. The first rotating part 22 is provided with a second driving device 27 for driving the second rotating part 23 to rotate and a second angle detector 28 for detecting the rotation angle of the second rotating part 23.

[0051] As needed, the first drive device 25 and the second drive device 27 can be servo motors.

[0052] The clamp 3 is located on the table surface of the rotating stage 21. It has a clamping structure 31 for clamping the inner reflecting prism, a clamping adjustment structure 32 for clamping and adjusting the Y-axis position and horizontal angle of the detector, and a pressing structure 33 for pressing the detector downward so that the detector can be bonded to the inner reflecting prism.

[0053] Combined with appendix Figure 3-4 Furthermore, the clamping structure 31 includes:

[0054] L-shaped plate 311 is disposed on the table surface of rotating table 21 along the X-axis direction;

[0055] The clamping member 312 is located at the outer end of the horizontal section of the L-shaped plate 311 along the X-axis direction, so as to cooperate with the vertical section of the L-shaped plate 311 to clamp the inner reflecting prism.

[0056] Among them, the upper end of the vertical section of the L-shaped plate 311 is provided with a pressing structure 33.

[0057] This allows the internal reflecting prism to be placed on the upper surface of the horizontal section of the L-shaped plate 311, and then the internal reflecting prism can be clamped by the clamping member 312 cooperating with the vertical section of the L-shaped plate 311.

[0058] As needed, the clamping member 312 can be a bolt screwed to the outer end of the horizontal section of the L-shaped plate 311;

[0059] As needed, to prevent dynamic friction between the clamping member 312 and the internal reflecting prism, the inner end of the clamping member 312 can be coaxially rotatably connected to a clamping head.

[0060] Combined with appendix Figure 3-4 Furthermore, the clamping adjustment structure 32 includes two vertical fixing rods 321 respectively disposed on both sides of the clamping structure 31. Each fixing rod 321 has a clamping adjustment member 322 disposed along the Y-axis direction at its upper end, and the inner end of the clamping adjustment member 322 is horizontally rotatably connected to a clamping part 323 to facilitate clamping and adjusting the Y-axis position of the detector. Each fixing rod 321 has a second adjustment member 324 disposed along the X-axis direction at its upper end for adjusting the X-axis position of the corresponding clamping adjustment member 322 to facilitate adjusting the X-axis position and horizontal angle of the detector.

[0061] This configuration allows the detector to be clamped by two opposing clamping adjustment members 322. The X-axis position of the detector can be adjusted by adjusting the axial position of the clamping adjustment members 322. The Y-axis position of the detector can also be adjusted by moving the two clamping adjustment members 322 along the Y-axis through the second adjustment member 324. Since the clamping part 323 is horizontally rotatably connected to the inner end of the clamping adjustment member 322, one of the second adjustment members 324 can be operated alone to move the corresponding clamping adjustment member 322 along the Y-axis, thereby causing the detector to rotate horizontally and thus achieving the function of adjusting the horizontal angle of the detector.

[0062] Since personnel can initially determine the angle of the detector when it is placed, the horizontal angle of the detector is not large and generally does not exceed ±5°. Therefore, the horizontal angle of the detector can be adjusted by the cooperation of the second adjustment member 324, the clamping adjustment member 322, and the clamping part 323.

[0063] Combined with appendix Figure 3-4 Furthermore, the upper end of the fixed rod 321 is movably connected to the upper end of the fixed rod 321 along the X-axis, and the movable block 325 is provided with a clamping adjustment member 322, and the movable block 325 is correspondingly connected to the second adjustment member 324; that is, the movable block 325 is moved by the second adjustment member 324, which in turn drives the corresponding second adjustment member 324 to move.

[0064] As needed, the second adjusting member 324 can be a bolt screwed to the movable block 325; the inner end of the second adjusting member 324 is a ball head; at this time, the horizontal section of the L-shaped plate 311 in the clamping structure 31 is provided with a supporting plane on both sides to support the movable block 325, so as to prevent the movable block 325 from rotating according to the rotation of the second adjusting member 324.

[0065] Combined with appendix Figure 5 The dual-optical-path structure 4 has an inner cavity of the mounting box 1 located above the clamp 3, which is used to detect whether the inner reflecting prism is horizontal and whether the detector is in the right position relative to the inner reflecting prism, so as to make the inner reflecting prism horizontal by adjusting the two-axis turntable 2 and the clamping structure 31 and to make the detector in the right position relative to the inner reflecting prism by adjusting the clamping adjustment structure 32.

[0066] Furthermore, the dual-optical-path structure 4 includes a collimating objective lens group 41, a CCD imaging objective lens 42, and a surface array CCD 43 arranged horizontally from bottom to top. A first beam splitter 44, tilted vertically at 45 degrees, is arranged between the collimating objective lens group 41 and the CCD imaging objective lens 42. A second beam splitter 45, parallel to the first beam splitter 44, is arranged on one side of the first beam splitter 44. A first illumination reticle 46 and a first point light source 47 are arranged sequentially on the side of the second beam splitter 45 away from the first beam splitter 44. A second illumination reticle 48 and a second point light source 49 are arranged sequentially above the second beam splitter 45.

[0067] Specifically, both the first illumination reticle 46 and the second illumination reticle 48 have cross-shaped light-transmitting holes.

[0068] When using it, step one: use the clamping structure 31 to pre-install the internal reflection prism;

[0069] Step 2: Find the maximum value of the image signal on the CCD43 array, determine the CCD pixels with image signals, and apply the formula to all pixel grayscale values ​​within the range of the CCD pixels with image signals.

[0070]

[0071]

[0072] Calculate the center position of the light spot;

[0073] Among them, I i Let (x) be the grayscale value of the i-th pixel after subtracting the background. n y n ) represents the coordinates of the centroid of the obtained image.

[0074] Step 3: Use a standard prism to determine the center position of the light spot (x). o y o If ), then Δx=x n-x o Δy=y n -y o

[0075] Step 4: Calculate the X-axis and Y-axis deviation angles of the internal reflecting prism based on the angle measurement parameters, which are θ respectively. x θ y ,

[0076]

[0077]

[0078] Where Δx and Δy are the displacements of the image point on the focal plane, respectively, and f is the focal length of the collimating objective lens group 41;

[0079] Step 5: Use the two-axis turntable 2 to adjust the angle of the internal reflecting prism to a horizontal position.

[0080] Furthermore, in step two, a threshold segmentation method is used to eliminate pixels without image signals.

[0081] After the position of the internal reflecting prism is adjusted, the dual-light path structure 4 switches the light source, making the first illumination reticle 46 work. The computer collects the output signal of the detector and guides the fixture 3 to adjust the position of the detector on the light transmission aperture of the internal reflecting prism according to the output voltage value of the detector, so that the detector output signal reaches the maximum value. Then, the computer realizes the ±45° field of view through the two-axis turntable 2 and realizes the ±5° field of view detection voltage output measurement through the second adjustment component 324, and plots the field of view and field of view detection performance distribution curve. According to the detection performance distribution curve, the detector position can be adjusted quantitatively, thereby realizing the quantitative assembly, adjustment and testing of the entire receiving system. Finally, the detector is gently squeezed by the pressing structure 33 to complete the bonding work between the detector and the internal reflecting prism.

[0082] It should be noted that the detector was pre-assembled with adhesive that would bond it to the internal reflecting prism.

[0083] Example 2, in conjunction with Appendix Figure 3-4 An internal reflection prism and detector bonding and adjustment device, based on the first embodiment, the clamp 3 further includes a base plate 34, the upper plate surface of the base plate 34 is provided with clamping adjustment structures 32 on both sides, and the upper plate surface of the base plate 34 is provided with clamping structures 31 at the position between the clamping adjustment structures 32; the top of the clamping structure 31 is provided with a pressing structure 33.

[0084] Specifically, the L-shaped plate 311 is disposed on the surface of the base plate 34 along the X-axis direction;

[0085] The lower end of the fixing rod 321 is fixedly connected to the surface of the base plate 34.

[0086] Example 3, in conjunction with Appendix Figure 3-4 An internal reflection prism and detector bonding and adjustment device, based on embodiment one or two, further includes, in addition to: clamping structure 31:

[0087] Slide rail 313 is mounted on the table surface of rotary table 21 along the X-axis, and L-shaped plate 311 is slidably connected to slide rail 313 along its axial direction.

[0088] The first adjusting component 314 is located at one end of the slide rail 313 along the X-axis direction and is used to adjust the X-axis position of the L-shaped plate 311.

[0089] This configuration allows the L-shaped plate 311 to move via the first adjustment component 314, which in turn moves the inner reflecting prism, causing the inner reflecting prism and the detector to move relative to each other on the X-axis.

[0090] In this embodiment, the second adjustment member 324 can be designed as a small-distance adjustment movable block 325. At this time, the relative position of the inner reflection prism and the detector on the X-axis can be adjusted by the first adjustment member 314, and the horizontal angle of the detector can be adjusted by the movable block 325. Compared with the first embodiment, it is more convenient and faster to adjust the relative position of the inner reflection prism and the detector on the X-axis.

[0091] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes falling within the meaning and scope of equivalents within this invention.
