Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical array probe accessories, and more specifically, to a calibration special turntable applicable to a two-dimensional stereoscopic imaging optical array probe 2D-S. Background Art
[0002] The two-dimensional stereoscopic imaging optical array probe is a high-speed and high-resolution optical imaging probe developed and produced by SPEC Company in the United States, which consists of two 128 photodiode linear arrays working independently. It can capture two-dimensional images of particles passing through the sample volume where the laser beams overlap. And the overlapping area of the light beams uniquely defines the depth of field (and the sample volume) of small particles. It can image particles as small as 10 microns at a speed of 200 meters per second. It greatly improves the determination of the sample volume and small particles less than 100 microns. As a precision detection device, the probe of 2D-S needs to be maintained once every three months. In order to ensure the accuracy of the measurement results of 2D-S, it needs to be calibrated regularly. Simple calibration is carried out every six months, and a comprehensive calibration is required once a year.
[0003] During the calibration process, a calibration special turntable is needed to simulate particles of different particle sizes, so as to correct the judgment standard of 2D-S for the particle size. The 2D-S instrument needs to maintain a stable position and posture during a long-term continuous observation process to obtain accurate measurement results. When calibrating with the calibration special turntable, some slight shaking or movement may lead to measurement errors, so the role of the calibration special turntable is very important.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to the attached Figure 1-8 , which is a calibration special turntable applicable to the 2D-S calibration of a two-dimensional stereoscopic imaging optical array probe disclosed by the present utility model.
[0022] Working principle:
[0023] The installation fixing bracket uses two semi-cross mounting plates and is fixedly connected by bolts on the 2D-S to form a stable base structure. A fixing frame composed of a double-strut structure, a stable guide rail plate 6 and a test installation box 7. Different standard diameter circles are evenly distributed on the acrylic plate 4 to replace standard particles. The acrylic plate 4 is driven by the motor 2 to rotate at a constant speed for high-speed and high-resolution calibration. The test installation box 7 rotates manually by 90° along the fixed track of the guide rail plate 6 for calibration in another direction.
[0024] Embodiment:
[0025] First, install the fixing frame 1 on the 2D-S probe. The fixing frame 1 is composed of two semi-cross mounting plates, and these two mounting plates are connected by bolts and fixed at the bottom of the probe to form a stable base structure. The fixing frame 1 adopts a double-strut structure, and a support frame 3 is fixedly installed at its top by bolts to ensure that the entire device has sufficient stability during the calibration process.
[0026] The support frame 3 is designed in the form of a double strut. This structure increases the overall strength of the support frame 3 and can stably support the entire calibration device. The support frame 3 is installed with a guide rail plate 6 at its top. The design of the guide rail plate 6 enables the test installation box 7 to move freely along the slide rail, providing convenient conditions for multi-angle calibration.
[0027] The bottom of the guide rail plate 6 is provided with a slide rail, and the test installation box 7 can slide freely along the slide rail. This design enables the test installation box 7 to move and adjust at different positions according to needs during the calibration process, thereby realizing multi-directional calibration.
[0028] The test installation box 7 is the core part of the calibration special turntable and is used to carry the 2D-S probe. The sliding connection between the installation box and the guide rail plate 6 ensures that the probe can be accurately calibrated at different positions during the calibration process, greatly improving the accuracy and flexibility of the calibration.
[0029] On both sides of the test installation box 7, a light-shielding box 5 and a DC motor 2 are respectively fixed. The main function of the light-shielding box 5 is to reduce the interference of ambient light, ensure that the images collected by the light array probe during the calibration process are not affected by external light, and thus improve the accuracy of calibration.
[0030] An acrylic plate 4 is provided between the test installation box 7 and the motor 2. Different standard diameter circular marks are evenly distributed on the acrylic plate 4. These circular marks are used to replace standard particles and serve as reference points for optical calibration during the calibration process. When the acrylic plate 4 rotates, these marks can simulate particles of different particle sizes for the 2D-S probe to image, so as to calibrate the measurement accuracy of the probe.
[0031] The DC motor 2 used in the present utility model is of the RF370 type, with a working voltage of 12V and a rotational speed reaching 15,000 revolutions per minute. This motor 2 drives the acrylic plate 4 to rotate, driving the calibration device to operate at a constant speed. By controlling the rotational speed of the motor 2, the rotational speed of the acrylic plate 4 can be precisely adjusted, thereby simulating the particle motion under different environments and further improving the calibration accuracy.
[0032] During calibration, first install the 2D-S probe on the test installation box 7 and fix all connection components. Start the DC motor 2 to drive the acrylic plate 4 to rotate at a set rotational speed. The 2D-S probe images the circular marks with standard diameters on the acrylic plate 4 during the calibration process, and the system automatically analyzes the measurement accuracy of the probe according to the imaging results.
[0033] After completing the calibration in one direction, the test installation box 7 can rotate 90° along the guide rail plate 6 to perform the calibration in another direction. Through this multi-directional calibration method, it is ensured that the measurement accuracy of the 2D-S probe at different angles can be effectively calibrated.
[0034] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and reference can be made to the description in the method part for related parts.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
