[0001] This utility model relates to the field of optical detection device technology, specifically to an adjustment device for an optical detection platform. Background Technology

[0002] In the field of optical inspection, optical inspection platforms are fundamental equipment for various optical measurements, analyses, calibrations, and other operations. Their core function is to provide a stable and precise installation and positioning environment for the optical inspection host (such as a camera or spectrometer) and the optical test piece being inspected.

[0003] In the prior art, the platform on which the optical test piece is placed is usually fixed. It may have a longitudinal adjustment function, and the test piece is fixedly clamped on the placement stage. However, the tilt angle of the test piece cannot be adjusted, which may affect the accuracy of the test results due to the deviation of the angle. Utility Model Content

[0004] (I) Technical problems to be solved The technical problem to be solved by this utility model is to overcome the defect that the angle of the object being measured is not adjustable, which may affect the detection results, and to provide an adjustment device for an optical detection platform.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an adjustment device for an optical inspection platform, including a base, a height-adjustable sliding table connected to the base, a placement platform hinged at the center of the sliding table, a positioning component on the placement platform, a fine-tuning component connected to the placement platform on the sliding table, the fine-tuning component including symmetrically arranged upright plates, a lead screw rotatably connected between the two upright plates, a motor fixed on one of the upright plates, one end of the lead screw rotatably connected to the motor, a slider threadedly connected to the lead screw rotatably, a connecting rod hinged to one side of the bottom of the placement platform, and the other end of the connecting rod hinged to the slider.

[0006] As an improvement: a sliding groove is provided on the sliding platform below the lead screw, and a limiting block is provided on the bottom surface of the slider. The limiting block matches the sliding groove and slides within the sliding groove.

[0007] As an improvement: the positioning component includes symmetrically arranged clamping plates, the clamping plates having an arc structure, a through hole provided on the placement platform, a bidirectional lead screw rotatably provided in the through hole, and a T-shaped piece provided at the bottom of the clamping plate, the T-shaped piece being threadedly connected to the bidirectional lead screw.

[0008] As an improvement: the horizontal width of the T-shaped part is greater than the width of the through hole, and the horizontal surface of the T-shaped part is in contact with the horizontal surface of the placement platform.

[0009] As an improvement: the base is provided with a U-shaped frame arranged symmetrically on the left and right, and a second lead screw is rotatably connected between the U-shaped frame and the base. Connecting blocks that fit with the U-shaped frame are provided on both sides of the sliding table. The connecting blocks are threadedly connected to the second lead screw. The two second lead screws rotate at the same frequency through the drive assembly.

[0010] As an improvement: the drive assembly includes a second motor fixedly mounted on one of the U-shaped frames, a second lead screw connected to the output end of the second motor, and synchronous pulleys fixedly mounted at the bottom of the two second lead screws, which are connected by a synchronous belt.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0020] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 As shown, an adjustment device for an optical inspection platform includes a base 1, a height-adjustable sliding table 2 connected to the base 1, a U-shaped frame 14 symmetrically arranged on the base 1, a lead screw 15 rotatably connected between the U-shaped frame 14 and the base 1, and connecting blocks 16 on both sides of the sliding table 2 that fit with the U-shaped frame 14. The connecting blocks 16 are threadedly connected to the lead screw 15, and the two lead screws 15 rotate at the same frequency through a drive assembly. Among them, the combination of appendix Figure 1 and Figure 3 As shown, the drive assembly includes a second motor 17 fixedly mounted on one of the U-shaped frames 14, a second lead screw 15 connected to the output end of the second motor 17, and two synchronous pulleys 18 fixedly mounted at the bottom of the two lead screws 15. The two synchronous pulleys 18 are connected to each other by a synchronous belt 19. During the testing process, motor 217 drives lead screw 215 to rotate. Under the transmission of synchronous pulley 18 and synchronous belt 19, the two lead screws 215 can rotate at the same frequency, thereby driving the sliding table 2 to move up and down stably. When lead screw 215 rotates forward, the sliding table 2 rises, and vice versa. By adjusting the height of the sliding table 2, the test piece can be easily adjusted to the axial position required for testing, so as to improve the accuracy of the test results. Combined with appendix Figure 3 As shown, a baffle 20 is provided on the outer wall of the lead screw 15 located above the synchronous pulley 18. The baffle 20 not only restricts the movement of the sliding table 2, but also protects the synchronous pulley 18 below the baffle 20, preventing the sliding table 2 from falling too far and causing damage to it.

[0023] To improve the accuracy and precision of test results, combined with the attached... Figure 1 and Figure 4As shown, a placement platform 3 is hinged at the center of the sliding table 2. Through its hinged arrangement, the placement platform 3 can be angled relative to the sliding table 2. The placement platform 3 is equipped with a positioning component. The sliding table 2 is equipped with a fine-tuning component connected to the placement platform 3. The fine-tuning component includes symmetrically arranged vertical plates. A lead screw 4 is rotatably arranged between the two vertical plates. A motor 5 is fixedly installed on one of the vertical plates. One end of the lead screw 4 is connected to the motor 5. A slider 6 is threadedly connected to the lead screw 4. A connecting rod 7 is hinged to one side of the bottom of the placement platform 3. The other end of the connecting rod 7 is hinged to the slider 6. Combined with appendix Figure 2 As shown, a sliding groove 8 is provided on the sliding table 2 below the lead screw 4, and a limiting block 9 is provided on the bottom surface of the slider 6. The limiting block 9 matches the sliding groove 8 and slides within the sliding groove 8. When adjusting the angle between the test piece and the detection optical path, motor 5 drives lead screw 4 to rotate. The rotation of lead screw 4 drives slider 6 to move, so as to correct the angle of the test piece. Under normal conditions, slider 6 is at the center position of lead screw 4. At this time, the placement stage 3 and the sliding stage 2 are horizontal. When lead screw 4 rotates clockwise, slider 6 moves in the direction of motor 5. At this time, the hinge end of placement stage 3 and connecting rod 7 descends. Conversely, the hinge end of placement stage 3 and connecting rod 7 rises. This design allows the placement stage 3 to undergo small angle changes, realizing continuous, accurate and controllable fine adjustment of the angle of the test piece, thus improving the accuracy of measurement and detection.

[0024] To ensure the safety of the Type 3 test piece on the adjustment platform, in conjunction with the attached... Figure 4 and Figure 5 As shown, the positioning component includes symmetrically arranged clamping plates 10, which have an arc-shaped structure. The placement platform 3 has a through hole 11, and a bidirectional lead screw 12 is rotatably arranged in the through hole 11. The bottom of the clamping plate 10 has a T-shaped piece 13, which is threadedly connected to the bidirectional lead screw 12. One end of the bidirectional lead screw 12 extends to one side of the placement platform 3 and has a knob. Among them, combined with the appendix Figure 5 As shown, the horizontal width of the T-shaped part 13 is greater than the width of the through hole 11, and the horizontal surface of the T-shaped part 13 is in contact with the horizontal surface of the placement platform 3. This design ensures that the clamping plate 10 can only move axially in the horizontal direction along the through hole 11. The test piece is placed between two arc-shaped clamping plates 10. The bidirectional lead screw 12 is driven to rotate by turning the knob. When the bidirectional lead screw 12 rotates clockwise, the distance between the two clamping plates 10 is shortened, fixing the smaller test piece. Conversely, the distance between the clamping plates 10 is increased to fix the larger test piece.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
