TECHNICAL FIELD

[0001] The utility model belongs to the field of medicinal material detection, concretely relates to an imaging detection device for traditional Chinese medicine and traditional Chinese medicine preparation. BACKGROUND

[0002] In the quality control process of traditional Chinese medicine and traditional Chinese medicine preparation, imaging detection technology plays an important role. Traditional quality detection methods mainly rely on chemical analysis, such as high performance liquid chromatography (HPLC), gas chromatography (GC) and the like. Although these methods can provide accurate component analysis results, they often take a long time and require a complex sample pretreatment process. In addition, for complex systems such as traditional Chinese medicine and its preparations, which are usually composed of multiple components, it is difficult to comprehensively evaluate their quality by relying solely on chemical analysis methods.

[0003] In recent years, with the development of imaging technology, methods for evaluating the appearance characteristics of drugs through image acquisition and analysis have gradually gained attention. For example, a common camera is used to take pictures of the surface of the drug and software analysis is used to identify surface defects, color changes, etc. For example, the Chinese patent with publication number CN220252360U discloses a disassembled medicine photographing box, which includes a photographing box body, a photographing lamp strip group, a pair of guide rails and a tray matched with the guide rails. The tray is provided with a medicine positioning groove.

[0004] However, the imaging detection devices in the prior art have certain limitations: on the one hand, most of these devices lack flexibility and cannot adjust the shooting angle or position according to different detection needs; on the other hand, when processing traditional Chinese medicine samples of different sizes or shapes, the existing devices may not provide sufficient adaptability, thereby affecting the detection efficiency and accuracy.

[0005] Therefore, the present application is proposed. UTILITY MODEL CONTENT

[0016] Compared with the prior art, the image acquisition module has the following beneficial effects:

[0017] 1.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides an imaging detection device for traditional Chinese medicine and its preparations, including a base plate 1. A detection stage 2 for placing the drug to be tested is provided on the base plate 1. The detection stage 2 and the base plate 1 are connected by a longitudinal slide rail 4. A transverse slide rail 3 is provided above the detection stage 2. A transversely movable image acquisition module 5 is provided on the transverse slide rail 3. The image acquisition module 5 includes a vertically arranged camera 51 and a light source 52.

[0025] The cross layout of the longitudinal slide rail 4 and the transverse slide rail 3 enables precise movement control of the detection stage 2 and the image acquisition module 5 in two-dimensional space, allowing for full-area scanning detection of the surface of Chinese medicine samples. The vertically set camera 51 and the light source 52 move synchronously to ensure the stability of the light incident angle and imaging distance, significantly improving the imaging quality of the microscopic features of Chinese medicine (such as the texture of the medicinal slices and the morphology of the preparation particles).

[0026] Preferably, the image acquisition module 5 further includes a frame 53 slidably mounted on the horizontal slide rail 3, a camera bracket 54 slidably mounted vertically in the frame 53, and a camera 51 fixedly mounted in the camera bracket 54. The combined structure of the frame 53 and the vertically sliding camera bracket 54 allows for independent adjustment of the camera 51 height during the detection process, adapting to the detection needs of Chinese herbal medicine samples of different thicknesses (such as whole medicinal materials and powder tablets). The modular design also facilitates equipment maintenance and component replacement.

[0027] Preferably, the upper surface of the frame 53 is provided with an adjusting bracket 55, on which an adjusting bolt 56 for adjusting the height of the camera 51 is installed, and the adjusting bracket 55 extends upward along the upper surface of the frame 53 for a distance and then extends to the side of the camera bracket 54 to form a protrusion, and the protrusion is also provided with a mounting hole parallel to the mounting direction of the camera 51, and the adjusting bolt 56 passes through the mounting hole and cooperates with the threaded hole of the camera bracket 54.

[0028] The meshing and cooperating structure of the adjusting bolt 56 and the threaded hole can achieve fine adjustment accuracy of the camera 51 height within ±0.2mm, and ensure accurate matching of the lens focal length and the sample surface, and the design of the protrusion avoids the operation space of the adjusting mechanism, and facilitates timely adjustment during the running gap of the equipment.

[0029] Further, the light source 52 is installed at the bottom of the frame 53, and the light source 52 includes a center-aperture light shield 521 and lamp beads 522 installed on the inner wall of the light shield 521, the center-aperture light shield 521 is arranged corresponding to the direction of the optical lens of the camera 51, and the axis of the center-aperture light shield 521 is collinear with the central axis of the optical lens of the camera 51.

[0030] The coaxial light source 52 design (the axis of the light shield 521 is collinear with the optical axis of the camera 51) effectively eliminates the interference of the reflection of the sample surface, and makes the imaging of the internal structure of traditional Chinese medicine (such as the vascular bundle of the slice) clearer, and further, a ring-distributed lamp bead 522 can be used in cooperation with the center-aperture light shield 521 to form a uniform shadowless lighting environment, which is especially suitable for the transmission imaging detection of semi-transparent traditional Chinese medicine preparations (such as paste prescriptions).

[0031] Preferably, the side edge of the frame 53 is provided with an alignment module 6, and the alignment module 6 includes a gas cylinder 61 and a probe 62, the gas cylinder 61 is fixedly installed on the frame 53, and the probe 62 is installed on the extending end of the gas cylinder 61, and the probe 62 is arranged towards the detection table 2, and is used for detecting the position of the adjacent side edge of the detection table 2 to realize position calibration.

[0032] The alignment module 6 drives the probe 62 to contact the edge of the detection table 2 through the gas cylinder 61, automatically compensates the mechanical assembly error and the cumulative displacement deviation of the slide rail, minimizes the error value between the image acquisition coordinate system and the actual position of the sample, and guarantees the spatial consistency of the detection data of multiple batches.

[0033] Preferably, two limit sensors 611 are installed on the gas cylinder 61, which are used to limit the highest position and the lowest position of the movement of the probe 62. The double-limit sensor 611 can prevent the probe 62 from being damaged by excessive downward pressure or lifted out of the effective detection area, and at the same time, the calibration stroke of the probe 62 is controlled within a safe range, so as to avoid the degradation of the equipment precision caused by frequent mechanical impact.

[0034] Preferably, at least two mutually parallel longitudinal sliding rails 4 are installed on the base plate 1, and the detection table 2 is slidingly arranged on the longitudinal sliding rails 4. The parallel design of multiple detection tables 2 supports the continuous detection of batch samples, and after a single detection table 2 completes scanning, it can be moved out of the working area through the longitudinal sliding rails 4 and replaced with a new sample, so that the utilization rate of the equipment is improved by at least 200%, which is particularly suitable for large-scale quality control scenes in traditional Chinese medicine production enterprises.

[0035] Preferably, the transverse sliding rail 3 and the longitudinal sliding rail 4 are electric sliding rails.

[0036] Or, the transverse sliding rail 3 and the longitudinal sliding rail 4 are pneumatically driven.

[0037] Specifically, the electric sliding rail scheme (servo motor + ball screw) can achieve a positioning accuracy of ±0.01 mm, which meets the high-resolution microscopic imaging requirements; the pneumatic driving scheme (air cylinder + magnetic switch) has a faster moving speed (≥10 cm / s), which is suitable for rapid screening scenes. The two driving modes are selected according to the requirements, so that the equipment can adapt to different detection accuracy and efficiency requirements of application scenes.

[0038] Further, during work, the first step is to initialize the system and set parameters, start the electric / pneumatic driving system, reset the detection table 2 to the initial position through the longitudinal sliding rail 4, rotate the camera support 54 by adjusting the bolt 56, so that the optical lens of the camera 51 is at a preset working height (such as 5 cm) from the light source 52, start the light source 52 and verify that the axis of the light shield 521 is collinear with the optical axis of the camera 51.

[0039] The second step is to calibrate the position of the detection table 2, the air cylinder 61 of the module 6 pushes the probe 62 to move down, the limit sensor 611 monitors the moving stroke in real time, and the probe 62 generates a position feedback signal after contacting the two adjacent sides of the detection table 2, calculates the horizontal / vertical offset, controls the transverse sliding rail 3 and the longitudinal sliding rail 4 to fine-tune the position of the camera 51 relative to the detection table 2 according to the offset, and until the detection value of the camera 51 enters the relatively central allowable error range.

[0040] The third step is to perform multi-detection table 2 parallel processing (optional), when multiple detection tables 2 are configured, the system moves each detection table 2 to the working area in a predetermined order, the idle detection table 2 is moved out of the loading position along the longitudinal sliding rail 4 for sample placement, and the detection table 2 loaded with the sample enters the scanning area.

[0041] The fourth step is to perform two-dimensional scanning image acquisition, the transverse sliding rail 3 drives the image acquisition module 5 to move horizontally (for example, stepping horizontally by 0.5 mm), and every time it moves to a sampling point, the longitudinal sliding rail 4 drives the detection table 2 to move longitudinally by 0.2 mm,

[0042] The camera 51 continuously shoots under the illumination condition that the optical axis is coaxial with the light source 52, automatically saves the image data with spatial coordinate information, and controls the relative movement of the detection table 2 and the camera 51 if the length or width of the medicine is too long, splices the photographed images, and forms complete medicine image data.

[0043] The fifth step is to perform dynamic focus compensation. When the detected height variation of the sample surface exceeds the focal length tolerance range (such as ±1mm), the image is unclear, the slide rail movement is paused, the adjusting bolt 56 is rotated for Z-axis fine adjustment (accuracy 0.2mm / turn), and after refocusing, the scanning is continued,

[0044] The sixth step is to perform data output and equipment reset. After scanning is completed, the detection table 2 automatically returns to the initial position, and a detection report containing the following information is generated: two-dimensional spliced high-definition image, feature area coordinate labeling data, light source 52 parameters, and spatial positioning log.
