[0002] Currently, point-spectral confocal displacement sensors are a relatively mature product. However, in the production process of domestically produced point-spectral confocal sensors, the alignment and adjustment of the light spot with the CMOS sensor in the spectrometer's optical engine is mostly not automated and still requires manual intervention. Because manual adjustment involves subjective differences, the consistency of the finished product may not be guaranteed, leading to significant variations in the sensors shipped from the factory. Utility Model Content

[0003] This application aims to provide a point spectral linear CMOS assembly and alignment device. By combining this assembly and alignment device with host computer quality assessment software, the subjective differences caused by manual assembly can be largely eliminated, thereby improving the consistency of the assembled products and solving the problem that there may be significant differences between the sensors shipped from the factory.

[0004] This application provides a point spectrum linear array CMOS assembly and alignment device, including: a base, a multi-axis manual slide, and a fixture; The base includes: a base plate, a first mounting part, and a second mounting part; both the first mounting part and the second mounting part are fixedly connected to the base plate and are opposite to each other on the Y-axis; The first mounting section is used for the fixed connection of the spectrometer's optomechanical components; A multi-axis manual slide table includes: a cross slide table for controlling movement on the X and Z axes, a lifting slide table for controlling movement on the Y axis, and a rotary slide table for controlling rotation about a first axis; the first axis is parallel to the Y axis; the fixed part of the cross slide table is fixedly connected to the second mounting part; The fixture is fixedly connected to the movable part of the rotary slide and is used to clamp the CMOS circuit board. Even when the CMOS circuit board is fixedly connected to the spectrometer's optical engine, the clamping of the fixture and the CMOS circuit board can still be released.

[0006] In some embodiments, the fixture is in the form of an OK clip.

[0015] Please see Figure 1 A point spectrum linear array CMOS assembly and alignment device includes: a base 1, a multi-axis manual slide 2, and a fixture 3.

[0016] The base 1 includes a base plate 11, a first mounting part 12, and a second mounting part 13. Both the first mounting part 12 and the second mounting part 13 are fixedly connected to the base plate 11, and more specifically, the fixing method can be using screws. The first mounting part 12 and the second mounting part 13 are opposite each other on the Y-axis.

[0017] Please see Figure 1 and Figure 3 The first mounting part 12 is used for the fixed connection of the spectrometer optical engine 4. After the spectrometer optical engine 4 is fixedly connected to the first mounting part 12, L-shaped blocks 4A are fixedly connected to both sides of the spectrometer optical engine 4 on the X-axis. The two L-shaped blocks 4A are used for the subsequent fixed connection of the CMOS circuit board 5, so as to realize the fixed connection between the CMOS circuit board 5 and the spectrometer optical engine 4.

[0018] Please see Figure 1 and Figure 3 The multi-axis manual slide 2 includes: a cross slide 21 for controlling movement along the X and Z axes, a lifting slide 22 for controlling movement along the Y axis, and a rotary slide 23 for controlling rotation along a first axis. Specifically, the lifting slide 22 is used horizontally, with its fixed portion fixedly connected to the movable portion of the cross slide 21, and the fixed portion of the rotary slide 23 fixedly connected to the movable portion of the lifting slide 22. The first axis is parallel to the Y axis.

[0019] The fixed part of the cross slide 21 is fixedly connected to the second mounting part 13, and the fixture 3 is fixedly connected to the movable part of the rotary slide 23.

[0020] Please see Figure 1 and Figure 3 Fixture 3 is used to clamp the CMOS circuit board 5.

[0021] Please see Figure 2 and Figure 3 More specifically, the fixture 3 clamps the CMOS circuit board 5 by first mounting the CMOS circuit board 5 onto a connecting plate 6, and then using the fixture 3 to clamp the connecting plate 6. Correspondingly, the CMOS circuit board 5 is fixedly connected to the two L-shaped blocks 4A of the spectrometer optical engine 4 by the connecting plate 6 being fixedly connected to the two L-shaped blocks 4A.

[0022] The connecting plate 6 has a through hole 6A at its center, which is used to align the spectrometer optical engine 4 with the CMOS circuit board 5. The CMOS circuit board 5 and the connecting plate 6 can be fixedly connected as follows: the CMOS circuit board 5 has first mounting holes 5A at each of its four corners, and the connecting plate 6 has four first oblong grooves 6B. The corresponding first mounting holes 5A and first oblong grooves 6B form a first mounting group 56, which is fitted into the first mounting group 56 using fasteners. The connecting plate 6 and the two L-shaped blocks 4A can also be fixedly connected as follows: the L-shaped blocks 4A have two second mounting holes 4B, and the connecting plate 6 has four second oblong grooves 6C. The corresponding second mounting holes 4B and second oblong grooves 6C form a second mounting group 46, which is fitted into the second mounting group 46 using fasteners.

[0023] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, the fixture 3 is in the form of an OK clip 32. Further, the fixture 3 includes a connecting seat 31 and an OK clip 32. The connecting seat 31 is used for fixed connection with the multi-axis manual slide 2. One side of the connecting seat 31 has a clamping portion 31A, and the opposite side has a third mounting portion 31B. The OK clip 32 is disposed on the third mounting portion 31B. Both the clamping portion 31A and the third mounting portion 31B have a contact surface 3A, and the clamping portion 31A also has a first clamping surface 3B.

[0024] First, attach the connecting plate 6 to the mating surface 3A, then rotate the bolt of the OK clamp 32 to move the trapezoidal block of the OK clamp 32, so that the elastic arm of the OK clamp 32 approaches the connecting plate 6. The second clamping surface 3C of the elastic arm cooperates with the first clamping surface 3B of the clamping part 31A to clamp the connecting plate 6.

[0025] Please see Figure 6 , Figure 7 and Figure 8 In some embodiments, based on the fixture 3 including a connecting seat 31 and an OK clamp 32, the clamping part 31A has two locations, and the space between the two clamping parts 31A is used to correspond to the second mounting group 46 of the CMOS circuit board 5 and the spectrometer optical engine 4. The third mounting part 31B corresponds to the position between the two clamping parts 31A, and the space on both sides of the third mounting part 31B is used to correspond to the second mounting group 46 of the CMOS circuit board 5 and the spectrometer optical engine 4.

[0026] After the CMOS circuit board 5 and the connecting plate 6 are clamped by the fixture 3, the space left between the two clamping parts 31A and the space left on both sides of the third mounting part 31B can be used to conveniently fix the connecting plate 6 to the two L-shaped blocks 4A of the spectrometer optical engine 4 by fasteners and the second mounting group 46.

[0027] The spectrometer optical engine 4 is mounted on the first mounting part 12, and the fixture 3 clamps the CMOS circuit board 5. Correspondingly, the spectrometer optical engine 4 and the CMOS circuit board 5 are opposite each other on the Y-axis. Using the multi-axis manual slide 2, the CMOS circuit board 5 can be moved along the X, Y, and Z axes, and can also be rotated and swung around a first axis parallel to the Y-axis to adjust the position of the spectrometer optical engine 4 aligned with the CMOS circuit board 5, ensuring that the photosensitive area of ​​the image board of the CMOS circuit board 5 is precisely aligned with the light spot of the spectrometer optical engine 4. After adjustment, the CMOS circuit board 5 is fixedly connected to the spectrometer optical engine 4. Even with the CMOS circuit board 5 fixedly connected to the spectrometer optical engine 4, the clamping of the fixture 3 and the CMOS circuit board 5 can still be released, meaning the spectrometer optical engine 4 will not interfere with the operation of the fixture 3. The clamping of the fixture 3 and the CMOS circuit board 5 is released, and the spectrometer optical engine 4 is removed from the first mounting part 12, completing the assembly and adjustment process.

[0028] Please see Figure 1 and Figure 4 In some embodiments, the first mounting portion 12 is T-shaped and includes a vertical portion 121 and a horizontal portion 122.

[0029] The top surface of the base plate 11 has a first groove 11A and a second groove 11B. The first groove 11A is used to position the vertical portion 121 relative to the base plate 11 on the X-axis, that is, the two outer walls of the vertical portion 121 on the X-axis are respectively attached to the two inner walls of the first groove 11A on the X-axis. The second groove 11B is used to position the second mounting portion 13 relative to the base plate 11 on the X-axis, that is, the two outer walls of the second mounting portion 13 on the X-axis are respectively attached to the two inner walls of the second groove 11B on the X-axis.

[0030] The bottom surface of the horizontal portion 122 has a third groove 122A, which is used to position the horizontal portion 122 relative to the vertical portion 121 on the Y-axis. That is, the outer walls of the two sides of the vertical portion 121 on the Y-axis are respectively attached to the inner walls of the two sides of the third groove 122A on the Y-axis.

[0031] The second mounting part 13 has a fourth groove 13A, which is used to position the multi-axis manual platform on the Z-axis, that is, the fixed part of the cross slide 21 is attached to the lower inner wall of the fourth groove 13A.

[0032] The multi-axis manual slide 2 has a relatively small range of movement in the X, Y, and Z axes. After the spectrometer optical engine 4 is installed in the first mounting part 12 and the CMOS circuit board 5 is clamped by the fixture 3, the spectrometer optical engine 4 and the CMOS circuit board 5 can be initially aligned. This ensures that the photosensitive area of ​​the image board of the CMOS circuit board 5 can be accurately aligned with the light spot of the spectrometer optical engine 4 through the adjustment of the multi-axis manual slide 2.

[0033] Please see Figure 1 and Figure 3 In some embodiments, the OK clamp 32 of the fixture 3 is on one side of the X-axis. The multiple adjustment levers of the multi-axis manual slide 2 are oriented towards the other side of the X-axis or upwards.
