Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, in particular to a pearl layer thickness detection system. BACKGROUND

[0002] In the pearl quality evaluation system, the pearl layer thickness occupies a pivotal position, and the thickness directly relates to the market value of the pearl. At present, the jewelry identification and pearl industry has mastered the technology of measuring the pearl layer thickness by using X-RAY equipment.

[0003] The current pearl layer thickness detection process is as follows: first, the operator opens the test chamber of the X-RAY equipment, and places the pearl in it, and then performs a single-direction pearl layer thickness test. After the first test is completed, the test chamber needs to be opened again, and the orientation of the pearl is adjusted to perform a second test in another direction. This process needs to be repeated two to three times to ensure the comprehensiveness and accuracy of the data. Finally, the average thickness of the pearl layer is calculated according to the data obtained by multiple tests.

[0004] However, in the operation process of the traditional X-RAY test equipment, the pearl in the test chamber is easy to roll. In order to obtain accurate average thickness of the pearl layer, the operator needs to frequently open the test chamber and adjust the placement position of the pearl, which prolongs the test time and makes it difficult to ensure the stability and accuracy of the test results. CONTENT OF THE INVENTION

[0005] The purpose of the embodiment of the present application is to provide a pearl layer thickness detection system to solve the problem that in the operation process of the traditional X-RAY test equipment, the pearl in the test chamber is easy to roll, in order to obtain accurate average thickness of the pearl layer, the operator needs to frequently open the test chamber and adjust the placement position of the pearl, which prolongs the test time and makes it difficult to ensure the stability and accuracy of the test results.

[0006] The pearl layer thickness detection system provided by the embodiment of the present application comprises a detector, a carrier table, a pearl support and a horizontal motion device.

[0007] The pearl support is erected above the carrier table, and the detector is arranged above the pearl support.

[0008] The pearl support is provided with a hollow clamping groove, and the clamping groove is used for placing the pearl to be tested.

[0009] When the pearl to be tested is placed on the clamping groove, the bottom of the pearl to be tested is in contact with the carrier table.

[0010] The horizontal motion device is connected to the carrier table, and is used for controlling the carrier table to move in the horizontal direction.

[0011] In the above technical solution, the pearl layer thickness detection system includes a detector, a stage, a pearl holder, and a horizontal motion device. During detection, the pearl to be measured is placed in the clamping groove of the pearl holder, ensuring that the bottom of the pearl is in contact with the stage. The detector is used to measure the initial direction thickness of the pearl. Due to the design of the pearl holder and the clamping groove, the pearl can remain stable during measurement. The horizontal motion device is used to control the movement of the stage in the horizontal direction, driving the pearl to be measured on the pearl holder to roll to a new position. This process can be accurately controlled to ensure that the pearl can roll to a predetermined angle. At the new position, the detector is used again to measure the thickness of the pearl. Through multiple rolling and measuring, the thickness data of the pearl in various directions can be obtained. All direction thickness data is collected, and the average thickness of the pearl layer is calculated using an algorithm. This embodiment reduces the time for operators to frequently open the test bin and adjust the placement position of the pearl by controlling the movement of the stage and the rolling of the pearl. Moreover, the pearl remains stable during testing and can roll to multiple angles for measurement, thereby ensuring the stability and accuracy of the test results.

[0012] In some optional embodiments, the clamping groove is a circular clamping groove, and the pearl holder is provided with a plurality of circular clamping grooves with different diameters.

[0013] In the above technical solution, the shape and size of the clamping groove are designed according to the shape and size of the pearl to ensure that the pearl can be stably placed in the clamping groove with the bottom in contact with the stage. This embodiment designs circular clamping grooves for the pearl holder, and these clamping grooves have different diameters to accommodate pearls of various shapes and sizes. Such a design ensures that the pearl can be stably placed in the circular clamping groove of the appropriate size, with the bottom closely contacting the stage, thereby maintaining a stable posture during pearl layer thickness testing.

[0014] Specifically, the diversification of circular clamping grooves provides suitable placement space for pearls of different sizes. Whether small, medium, or large pearls, there is a circular clamping groove that matches them, so that the pearls do not shake or roll during testing due to size mismatch, thereby affecting the accuracy of the test.

[0015] In addition, this design also takes into account the shape characteristics of the pearl. Since pearls usually have a nearly spherical appearance, circular clamping grooves can better fit the surface of the pearl, providing a larger contact area and more stable support. This helps to reduce the deformation of the pearl due to uneven stress during testing, thereby further improving the accuracy and reliability of the test.

[0016] In some optional embodiments, a flexible velvet layer is provided on the stage.

[0017] In the above technical solution, the flexible velvet layer covers the object table to protect the pearls and prevent the pearl samples in contact with the object table from being worn during rolling. The flexible velvet layer provides additional cushioning and protection for the pearls placed on the object table due to its soft texture and delicate touch. In addition, the flexible velvet layer also has a certain adsorption, which can slightly fix the position of the pearl.

[0018] In some optional embodiments, the card slot is coated with protective oil inside.

[0019] In the above technical solution, the card slot of the pearl support is coated with protective oil inside to avoid wear and tear on the pearl during placement and rolling. The protective oil provides an additional layer of cushioning for the movement of the pearl within the card slot due to its lubricating and protective properties. When the pearl is placed in the card slot or needs to roll in the card slot for different direction thickness measurement, this layer of protective oil can effectively reduce the friction between the pearl and the card slot wall, thereby significantly reducing the risk of damage to the surface of the pearl. In addition, the protective oil also has certain anti-rust and anti-corrosion functions, which can protect the inside of the card slot from being eroded by environmental factors such as moisture and oxidation, prolonging the service life of the card slot, and also providing a cleaner and safer testing environment for the pearl.

[0020] In some optional embodiments, further comprising: a lifting device; the lifting device is used to control the movement of the detector in the Z-axis direction.

[0021] In the above technical solution, by introducing the lifting device, we can flexibly adjust the distance between the detector and the pearl according to the size, shape and testing requirements of the pearl to be tested. This adjustment not only helps to ensure that the detector can capture clearer and more accurate X-ray images, thereby improving the accuracy and reliability of the test; at the same time, it can also adapt to different sizes of pearls, so that the entire detection system has a more extensive application range. Specifically, when testing smaller size pearls, the detector can be lowered closer to the pearl by the lifting device to capture the changes in pearl layer thickness more meticulously. Conversely, when testing larger size pearls, the detector can be raised to an appropriate position to ensure that the entire pearl can be completely included in the test range.

[0022] In some optional embodiments, the pearl support includes a metal support.

[0023] In the above technical solution, the metal texture of the metal support is greatly different from the pearl material, which facilitates clear imaging of the pearl layer. The metal support has high density and stable physical properties, and can form a clear contrast under X-ray irradiation, thereby highlighting the outline and internal structure of the pearl. This contrast effect helps the detector to more accurately capture the changes in the thickness of the pearl layer, improving the accuracy and reliability of the test. In addition, the metal support also has good stability and durability, and can withstand various forces and vibrations that may occur during the test, ensuring that the pearl maintains a stable posture during the test. This stability is crucial for obtaining high-quality X-ray images and accurate test results.

[0024] In some optional embodiments, the horizontal motion device includes an X-axis transmission screw and a Y-axis transmission screw.

[0025] In the above technical solution, by driving the X-axis transmission screw and / or the Y-axis transmission screw, the object table is moved along the horizontal X-axis direction and / or the Y-axis direction, thereby driving the pearl on the pearl support to roll. The X-axis transmission screw and the Y-axis transmission screw can realize smooth and continuous movement of the object table in the respective axial direction through precise thread design and driving mechanism. This movement method not only has high precision and high repeatability, but also can be flexibly adjusted according to the test requirements.

[0026] In some optional embodiments, the object table includes a rectangular object table.

[0027] In some optional embodiments, the horizontal motion device further includes: a rotating shaft; the rotating shaft is connected to the center of the object table.

[0028] In the above technical solution, by driving the rotating shaft to rotate, the object table is rotated, thereby driving the pearl on the pearl support to roll.

[0029] In some optional embodiments, the object table includes: a circular object table.

[0030] In the above technical solution, on the basis of introducing the rotating shaft, a circular object table is selected as the shape of the object table, and the design of the circular object table matches the rotation mode of the rotating shaft. BRIEF DESCRIPTION OF DRAWINGS

[0038] Among them, the pearl support is provided with at least one clamping groove, and the shape of the clamping groove can be circular, square, rhombic, rectangular, etc. The pearl support is not in contact with the object table, and the pearl support is erected above the object table; when the object table moves, the object table moves relative to the pearl support.

[0039] In the embodiments of the present application, the pearl layer thickness detection system includes a detector 1, a stage 2, a pearl holder 3, and a horizontal motion device 4. During detection, the pearl to be detected 5 is placed in the clamping groove 31 of the pearl holder 3, ensuring that the bottom of the pearl is in contact with the stage 2. The detector 1 is used to measure the initial direction thickness of the pearl. Due to the design of the pearl holder 3 and the clamping groove 31, the pearl can remain stable during the measurement process. The horizontal motion device 4 is used to control the movement of the stage in the horizontal direction, driving the pearl to be detected 5 on the pearl holder to roll to a new position. This process can be accurately controlled to ensure that the pearl can roll to a predetermined angle. At the new position, the detector 1 is used again to measure the thickness of the pearl. Through multiple rolling and measuring, the thickness data of the pearl in various directions can be obtained. Collecting all the thickness data in various directions, the average thickness of the pearl layer is calculated using an algorithm. By controlling the movement of the stage and the rolling of the pearl, the present embodiment reduces the time for the operator to frequently open the test bin and adjust the placement position of the pearl. Moreover, the pearl remains stable during the test process and can roll to multiple angles for measurement, thereby ensuring the stability and accuracy of the test results.

[0040] In some optional embodiments, the clamping groove is a circular clamping groove, and the pearl holder 3 is provided with a plurality of circular clamping grooves with different diameters.

[0041] In the embodiments of the present application, the shape and size of the clamping groove are designed according to the shape and size of the pearl, ensuring that the pearl can be stably placed in the clamping groove with the bottom in contact with the stage. The present embodiment designs circular clamping grooves for the pearl holder 3, and these clamping grooves have different diameters to accommodate pearls of various shapes and sizes. Such a design ensures that the pearl can be stably placed in the circular clamping groove of the appropriate size, with the bottom closely contacting the stage, thereby maintaining a stable posture during the pearl layer thickness test.

[0042] Specifically, the diversification of circular clamping grooves provides suitable placement space for pearls of different sizes. Whether small, medium or large pearls, there is a circular clamping groove that matches them, so that the pearls do not shake or roll during the test process due to size mismatch, thereby affecting the accuracy of the test.

[0043] In addition, this design also takes into account the shape characteristics of the pearl. Since the pearl usually has a nearly spherical appearance, the circular clamping groove can better fit the surface of the pearl, providing a larger contact area and more stable support. This helps to reduce the deformation of the pearl caused by uneven force during the test process, thereby further improving the accuracy and reliability of the test.

[0044] In some optional embodiments, a flexible velvet layer 21 is provided on the stage.

[0045] In the embodiments of the present application, the flexible velvet layer 21 is covered on the object table to protect the pearls and prevent the pearl samples in contact with the object table from being worn during rolling.

In addition, the flexible velvet layer 21 also has a certain adsorption, which can slightly fix the position of the pearl.

[0046] In some optional embodiments, the card slot is coated with protective oil inside.

[0047] In the embodiments of the present application, the card slot of the pearl holder 3 is coated with protective oil to avoid wear and tear of the pearl during placement and rolling. The protective oil provides an additional layer of cushioning for the movement of the pearl in the card slot due to its lubricity and protective properties. When the pearl is placed in the card slot or needs to roll in the card slot for thickness measurement in different directions, this layer of protective oil can effectively reduce the friction between the pearl and the wall of the card slot, thereby significantly reducing the risk of damage to the surface of the pearl. In addition, the protective oil also has certain anti-rust and anti-corrosion functions, which can protect the inside of the card slot from being eroded by environmental factors such as moisture and oxidation, prolonging the service life of the card slot, and also providing a cleaner and safer testing environment for the pearl.

This adjustment not only helps to ensure that the detector 1 can capture clearer and more accurate X-ray images, thereby improving the accuracy and reliability of the test; at the same time, it can also adapt to pearls of different sizes, so that the entire detection system has a more extensive application range. Specifically, when testing smaller pearls, the detector 1 can be lowered closer to the pearl by the lifting device 6 to capture the changes in pearl layer thickness more meticulously. Conversely, when testing larger pearls, the detector 1 can be raised to an appropriate position to ensure that the entire pearl can be completely included in the test range.

[0051] In some optional embodiments, the pearl holder 3 includes a metal holder.
