Description

Technical Field

[0001] This utility model belongs to the field of jewelry testing technology, specifically a testing module combination applicable to various types of jewelry. Background Technology

[0002] Jewelry testing equipment plays a crucial role in identification and composition analysis, but its rapid and accurate detection of various types of jewelry still has limitations. A search revealed patent CN112683977B, a "COVID-19 Detection Module Based on Multi-Target Site Antibody Combination," which achieves high-sensitivity detection through changes in electrical signals and is suitable for recognizing specific antigens or protein molecules in the biomedical field; however, it lacks applicability to non-biological materials such as precious metals and gemstones. Meanwhile, patent CN108181273B, a "Shipborne Multifunctional Dual-Probe Online Detection Device for Algal Fluorescence Parameters," improves detection accuracy through multi-wavelength excitation light sources and a dual-probe system, but it is only suitable for biological samples with specific fluorescence characteristics, failing to meet the differentiated detection needs of inorganic jewelry materials. While existing technical solutions offer some flexibility, there is still room for improvement in terms of compatibility with various jewelry materials, functional module expansion, and integration of diverse detection methods. Utility Model Content

[0003] The purpose of this invention is to provide a detection module assembly applicable to various types of jewelry, addressing the problems of limited detection targets, poor functional module expandability, single detection methods, and low level of intelligence in existing technologies. Through modular design and flexible combination of diverse detection units, it enables rapid identification and accurate analysis of different types of jewelry.

[0004] This utility model provides a detection module assembly applicable to various types of jewelry, including a main housing, a detection unit group, and an intelligent control module. The main housing is characterized by comprising a support plate, side frames, and a top cover. The support plate is a horizontally arranged rectangular flat plate with multiple positioning grooves on its upper surface for fixing the detection unit group. The side frames are vertically connected to the support plate and have slide rails on their inner walls, extending vertically for mounting the top cover. The top cover is detachable, with a slider on its lower surface that matches the slide rails. The slider and slide rails work together to move the top cover up and down, thereby adjusting the height of the internal space.

[0005] The detection unit group consists of multiple independent functional modules, including an optical detection module, an X-ray fluorescence detection module, and a Raman spectroscopy detection module. Each functional module has an independent housing, with a positioning protrusion on the bottom of the housing that matches the positioning groove on the support plate. The functional module is fixed by inserting the positioning protrusion into the positioning groove. The optical detection module includes a multi-wavelength light source and a photodetector. The multi-wavelength light source is evenly distributed along the circumference, and the photodetector is located at the center of the light source. The two are connected to the intelligent control module via a signal transmission cable. The X-ray fluorescence detection module includes an X-ray emitter and a receiver, forming a fixed detection channel between them. The jewelry to be tested is placed in the channel, and the receiver collects the fluorescence signal and transmits it to the intelligent control module via a data cable. The Raman spectroscopy detection module includes a laser emitter and a spectrometer. The laser emitted by the laser emitter is focused onto the surface of the jewelry to be tested by a focusing lens, and the reflected light signal is captured by the spectrometer and transmitted to the intelligent control module.

[0006] The intelligent control module is installed on one side of the main housing and integrates a central processing unit, a storage unit, and a communication interface. The central processing unit is connected to each functional module via signal transmission cables and is used to receive and process detection signals; the storage unit stores detection data and algorithm models; and the communication interface is used for data interaction with external devices. A touch screen is provided on the outer surface of the intelligent control module to display detection results and the user interface.

[0007] The detection module assembly applicable to various types of jewelry provided by this utility model is characterized by the connection method between the main housing and the detection unit group. The support plate and the side frame are fixed with bolts. The bolts pass through through holes on the edge of the support plate and are screwed into pre-set threaded holes on the inner side of the side frame, achieving a secure connection. The functional modules in the detection unit group are initially fixed by the cooperation of positioning protrusions and positioning grooves. Simultaneously, a locking device is provided on the side of the functional module's outer shell. The locking device includes a knob and a pressure plate. When the knob is rotated, it drives the pressure plate to press inward against the inner wall of the side frame, thereby further enhancing the stability of the functional module.

[0008] The present invention provides a detection module assembly applicable to various types of jewelry, characterized by the collaborative working principle between its functional modules. When the jewelry to be tested is placed in the detection area, the intelligent control module sequentially activates each functional module according to a preset program for detection. The optical detection module first performs a preliminary classification of the jewelry by exciting the optical properties of the jewelry surface with a multi-wavelength light source. A photodetector collects the reflected light signal and transmits it to the central processing unit. The central processing unit, combined with the algorithm model in the storage unit, determines the approximate category of the jewelry material. Subsequently, the X-ray fluorescence detection module is activated, analyzing the elemental composition of the jewelry through fluorescence signals to further confirm the material type. Finally, the Raman spectroscopy detection module analyzes the molecular structure of the jewelry, supplementing detailed information for material identification. The detection results of each functional module are summarized by the intelligent control module, and after comprehensive analysis, a final detection report is generated.

[0009] The detection module assembly applicable to various types of jewelry provided by this utility model is characterized by the expandability and interchangeability of its functional modules. The number of positioning slots on the support plate can be adjusted according to actual needs. Adding a new functional module only requires designing a positioning protrusion that matches the positioning slot for quick installation. For example, if an infrared spectroscopy detection module needs to be added, simply design the bottom of the infrared spectroscopy detection module's housing to match the shape of the positioning slot and secure it with a locking device. Furthermore, the housings of all functional modules adopt a uniform size and interface standard, facilitating replacement and upgrades.

[0010] The detection module assembly applicable to various types of jewelry provided by this utility model is further characterized by the optimized design of the intelligent control module. The central processing unit incorporates multiple algorithm models, enabling automatic switching of detection modes based on different jewelry types. For example, for precious metal jewelry, the X-ray fluorescence detection module is activated first; for gemstone jewelry, the Raman spectroscopy detection module is activated first. Furthermore, the intelligent control module connects to a cloud server via a communication interface, allowing for real-time updates of algorithm models and detection parameters, thereby improving detection accuracy and applicability.

[0011] The detection module assembly applicable to various types of jewelry provided by this utility model is characterized by its compact and portable overall structure. The main housing is made of lightweight, high-strength material, and the thickness of the side frames and top cover has been precisely calculated to reduce overall weight while ensuring strength. The slider and rail design of the top cover allows for adjustable internal height to accommodate jewelry of different sizes. Furthermore, the bottom of the main housing is equipped with an anti-slip pad to prevent displacement of the device during use.

[0012] This utility model provides a testing module assembly applicable to various types of jewelry. Through modular design, it achieves flexible combination and expansion of functional modules, solving the problems of limited testing methods and non-interchangeable functional modules in existing technologies. Each functional module operates independently yet cooperates with others, significantly improving testing efficiency and accuracy. Simultaneously, the introduction of an intelligent control module enhances the equipment's intelligence, meeting the increasingly diverse testing needs of the jewelry industry.

[0020] This utility model provides a detection module assembly suitable for various types of jewelry, the overall structure of which is as follows: Figure 1As shown, the main housing 1 consists of a support plate 2, side frames 3, and a top cover 4. The support plate 2 is a horizontally arranged rectangular flat plate structure with multiple positioning grooves 7 on its upper surface for fixing the functional modules in the detection unit group. The side frames 3 are vertically connected to the perimeter of the support plate 2, and are securely connected by bolts passing through through holes on the edge of the support plate 2 and screwing into pre-set threaded holes on the inner side of the side frames 3. The inner sidewall of the side frames 3 is provided with a slide rail 5, which extends vertically and cooperates with the slider 6 on the lower surface of the top cover 4, allowing the top cover 4 to move up and down along the slide rail 5, thereby adjusting the height of the internal space to accommodate jewelry of different sizes to be tested. The top cover 4 adopts a detachable design for easy maintenance and upgrades of the equipment.

[0021] The detection unit group consists of multiple independent functional modules, including optical detection module 8, X-ray fluorescence detection module 9, and Raman spectroscopy detection module 10, arranged as follows: Figure 2 As shown. Each functional module has an independent housing. The bottom of the housing has a positioning protrusion 15 that matches the positioning groove 7 on the support plate 2. The positioning protrusion 15 is inserted into the positioning groove 7 to achieve initial fixation. A locking device 16 is provided on the side of the functional module's housing. The locking device 16 includes a knob and a pressure plate. When the knob is turned, the pressure plate presses inward against the inner wall of the side frame 3, further enhancing the stability of the functional module. The optical detection module 8 includes a multi-wavelength light source and a photodetector. The multi-wavelength light source is evenly distributed along the circumference, and the photodetector is located at the center of the light source. The two are connected to the intelligent control module 11 through a signal transmission cable. The X-ray fluorescence detection module 9 includes an X-ray emitting end and a receiving end. A fixed detection channel is formed between the emitting end and the receiving end. The jewelry to be tested is placed in the channel, and the receiving end collects the fluorescence signal and transmits it to the intelligent control module 11 through a data cable. The Raman spectroscopy detection module 10 includes a laser emitter and a spectrometer. The laser emitted by the laser emitter is focused onto the surface of the jewelry to be tested through a focusing lens. The reflected light signal is captured by the spectrometer and transmitted to the intelligent control module 11.

[0022] The intelligent control module 11 is installed on one side of the main housing 1, and its structure is as follows: Figure 3 As shown, the internal components include a central processing unit 13, a storage unit, and a communication interface 14.

[0023] like Figure 4As shown, the detection module assembly of this utility model has good scalability and interchangeability. The number of positioning slots 7 on the support plate 2 can be adjusted according to actual needs. Adding a new functional module only requires designing a positioning protrusion 15 that matches the positioning slot 7 for quick installation. For example, if an infrared spectroscopy detection module needs to be added, simply design the bottom of the infrared spectroscopy detection module's housing to match the shape of the positioning slot 7 and fix it with the locking device 16. The housings of each functional module adopt a uniform size and interface standard, facilitating replacement and upgrades. Furthermore, the central processing unit 13 has multiple built-in algorithm models that can automatically switch detection modes according to different jewelry types.

[0024] Figure 5 The demonstration showcased the overall workflow of the equipment and the collaborative working principles of its various functional modules. When the jewelry to be tested is placed in the detection area, the intelligent control module 11 sequentially activates each functional module according to a preset program. First, the optical detection module 8 performs preliminary classification of the jewelry by exciting the optical properties of the jewelry surface with multi-wavelength light sources. A photodetector collects the reflected light signals and transmits them to the central processing unit 13. The central processing unit 13, combined with the algorithm model in the storage unit, determines the approximate category of the jewelry's material. Subsequently, the X-ray fluorescence detection module 9 is activated, analyzing the elemental composition of the jewelry through fluorescence signals to further confirm the material type. Finally, the Raman spectroscopy detection module 10 analyzes the molecular structure of the jewelry, supplementing detailed information for material identification. The detection results of each functional module are summarized by the intelligent control module 11, and after comprehensive analysis, a final detection report is generated. During the detection process, the signal transmission path is clear, and each functional module operates independently yet cooperates with each other, significantly improving detection efficiency and accuracy.

[0025] The main housing 1 is made of lightweight, high-strength materials. The thickness of the side frames 3 and top cover 4 has been precisely calculated to reduce overall weight while ensuring strength. The slider 6 and slide rail 5 design of the top cover 4 allow for adjustable internal height to accommodate jewelry of different sizes. Anti-slip pads are provided on the bottom of the main housing 1 to prevent displacement during use. This compact and portable design enables flexible application in various scenarios, meeting the increasingly diverse testing needs of the jewelry industry.

[0026] In practical applications, the detection module assembly of this invention can be widely used in jewelry appraisal institutions, jewelry processing plants, and high-end jewelry retail stores. For example, in a jewelry appraisal institution, when a customer brings in a piece of jewelry of unknown material, the operator simply places the jewelry in the testing area and initiates the testing program via the touch screen 12. The intelligent control module 11 sequentially activates each functional module according to a preset program to perform the tests, ultimately generating a detailed test report, including the jewelry's material category, elemental composition, and molecular structure information. In jewelry processing plants, this equipment can be used for rapid testing of semi-finished jewelry during the production process to ensure that product quality meets standards. In high-end jewelry retail stores, this equipment can serve as a sales aid, helping sales staff showcase the true materials and quality of jewelry to customers, thereby increasing customer trust and purchasing intention.

[0027] This invention achieves flexible combination and expansion of functional modules through modular design, solving the problems of limited detection methods and non-interchangeable functional modules in existing technologies. Each functional module operates independently yet cooperates with others, significantly improving detection efficiency and accuracy. Simultaneously, the introduction of an intelligent control module enhances the equipment's intelligence, meeting the increasingly diverse detection needs of the jewelry industry. The compact and portable design of the main casing allows for flexible application in various scenarios, further expanding its applicability.

[0028] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.

[0029] In a jewelry appraisal institution, when a client brings in a piece of jewelry of unknown material, the operator first places the jewelry to be tested in the testing area. At this time, the top cover 4 is adjusted to an appropriate height through the cooperation of the slider 6 and the slide rail 5 to ensure that the jewelry can be accurately positioned and is not affected by external interference. The positioning groove 7 on the support plate 2 is used to fix the various functional modules, including the optical detection module 8, the X-ray fluorescence detection module 9, and the Raman spectroscopy detection module 10, to ensure their stability during the testing process. Subsequently, the operator starts the testing program through the touch display screen 12, and the intelligent control module 11 sequentially starts each functional module to perform the test according to the preset program.

[0030] First, the multi-wavelength light sources in the optical detection module 8 are uniformly distributed along the circumference, emitting light signals of different wavelengths onto the surface of the jewelry to be tested. A photodetector, located at the center of the light sources, collects the reflected light signals and transmits the data to the central processing unit 13 via a signal transmission cable. The central processing unit 13, combined with the algorithm model in the storage unit, analyzes the intensity and wavelength characteristics of the reflected light signals to preliminarily determine the approximate category of the jewelry material. For example, for gemstone jewelry with specific optical properties, the system can quickly identify its possible material range.

[0031] Next, the X-ray fluorescence detection module 9 is activated. Its X-ray emitting end emits high-energy X-rays towards the jewelry under test, exciting electron transitions in the atoms inside the jewelry, thereby generating a characteristic fluorescence signal. After the receiving end captures the fluorescence signal, it is transmitted to the central processing unit 13 via a data cable. The central processing unit 13 uses a built-in algorithm model to analyze the energy distribution of the fluorescence signal to further confirm the elemental composition of the jewelry. This step is particularly suitable for the detection of precious metal jewelry, such as gold or platinum, and can accurately identify its purity and alloy composition.

[0032] Finally, the Raman spectroscopy detection module 10 is activated. The laser emitted by the laser emitter is focused onto the surface of the jewelry to be tested through a focusing lens, where it undergoes inelastic scattering with the jewelry molecules. The reflected light signal is captured by the spectrometer and transmitted to the central processing unit 13 via a signal transmission cable. The central processing unit 13 analyzes the peak positions and intensities of the Raman spectrum to obtain detailed information about the molecular structure of the jewelry. This step can provide a deeper level of material identification for gemstone jewelry, such as distinguishing between natural and synthetic diamonds.

[0033] The test results from each functional module are aggregated into the intelligent control module 11, where they are comprehensively analyzed to generate a final test report. The report includes the jewelry's material type, elemental composition, and molecular structure information, displayed on the touchscreen display 12 for the operator to view. Furthermore, the intelligent control module 11 connects to a cloud server via the communication interface 14 to update the algorithm model and test parameters in real time, ensuring that the test accuracy and applicability meet the latest requirements.

[0034] In jewelry processing plants, this equipment can be used for quality control during the production process. For example, after a batch of semi-finished jewelry has completed initial processing, operators place each piece in the inspection area and initiate an automatic inspection program. The intelligent control module 11 prioritizes the X-ray fluorescence detection module 9 according to a preset program to quickly analyze the elemental composition of the jewelry, ensuring it meets design standards. If the inspection results are abnormal, the system will alert the operator via the touchscreen display 12 and record the abnormal data for subsequent traceability.

[0035] In high-end jewelry retail stores, this device can serve as a sales aid. Sales staff place the jewelry in the testing area and initiate the testing process via the touchscreen display 12, showcasing the jewelry's true material and quality information to the customer. For example, for a ring labeled "natural sapphire," the Raman spectroscopy module 10 can verify whether its molecular structure matches that of natural sapphire, thereby increasing customer trust and purchase intention.

[0036] This invention achieves flexible combination and expansion of functional modules through modular design. For example, if an infrared spectroscopy detection module needs to be added, only a positioning protrusion 15 matching the positioning slot 7 needs to be designed and fixed by the locking device 16. The outer shell of the newly added modules adopts a uniform size and interface standard, facilitating replacement and upgrades. In addition, each functional module operates independently yet cooperates with each other, significantly improving detection efficiency and accuracy. This design enables the equipment to be flexibly applied in various scenarios, further expanding its applicability.

[0037] The main housing 1 is made of lightweight, high-strength materials. The thickness of the side frames 3 and top cover 4 has been precisely calculated to reduce overall weight while ensuring strength. The slider 6 and slide rail 5 design of the top cover 4 allow for adjustable internal height to accommodate jewelry of different sizes. Anti-slip pads are provided on the bottom of the main housing 1 to prevent displacement during use and ensure stability during the testing process. This compact and portable design enables the device to be flexibly applied in various scenarios, meeting the increasingly diverse testing needs of the jewelry industry.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
