Description

Technical Field

[0001] This invention relates to the field of LIBS detection technology, specifically to a multi-morphological material feeding structure and a LIBS detection and analysis system. Background Technology

[0002] In existing technologies, materials analysis and testing typically rely on various traditional mechanical devices and testing systems. In the field of LIBS (Laser-Induced Breakdown Spectroscopy) analysis, these devices are mostly designed as handheld or benchtop models, primarily used for material identification, compositional analysis, and quality control. These devices often include drive-driven grinding equipment or other types of material pretreatment equipment, their main function being to prepare samples for LIBS testing. In terms of application scenarios, these devices are widely used in laboratory analysis, industrial testing, and quality monitoring. For example, handheld LIBS analyzers are often used for rapid on-site analysis of metallic materials, while benchtop devices are used for more precise laboratory analysis.

[0003] The main challenge facing existing LIBS analysis systems is their poor adaptability to materials of various shapes. Traditional transmission grinding equipment and handheld LIBS devices typically lack pre-processing capabilities for materials of multiple shapes, which limits the application range and efficiency of the testing equipment. This is especially true when dealing with non-standard shaped materials such as columnar, polygonal, or powdery materials, where existing equipment often fails to provide effective support. Furthermore, due to the lack of flexible and adaptable feeding mechanisms, existing testing equipment cannot effectively adjust the relative position between the material and the testing equipment, which may affect the accuracy and efficiency of the testing in some cases. Therefore, existing technologies face significant limitations when processing materials of multiple shapes, making it difficult to provide a technical solution for detecting multiple materials perpendicularly at the optimal angle. This may lead to low analytical efficiency or inaccurate results in practical applications. Summary of the Invention

[0004] This application provides a multi-form material feeding structure and a LIBS detection and analysis system, the main purpose of which is to solve the problem of difficulty in providing a technical solution for detecting multiple materials vertically at the optimal angle.

[0005] To achieve the above objectives, a first aspect of this application provides a multi-form material feeding structure, comprising:

[0008] The feeding mechanism is movably installed in the inner cavity of the machine body. In the first state, the feeding mechanism is located outside the machine body. In the second state, the feeding mechanism is located below the grinding mechanism. In the third state, the feeding mechanism is located below the detector.

[0013] In one feasible implementation, the feeding mechanism includes: a feeding frame, which is fixedly connected to the drive end of the electric push rod at the front side; an upper top plate is provided at the top of the feeding frame; an upwardly angled opening is provided on the front side of the upper top plate for workers to place the material to be tested; a rectangular detection port is provided in the middle of the upper top plate; a placement platform, which is movably disposed in the inner cavity of the feeding frame; the top end face of the placement platform is used to place the material to be tested; and two strip grooves. A limiting mechanism is provided on both sides of the connection position between the feeding frame and the output end of the electric push rod, which are opened vertically along the direction. When the electric push rod drives the feeding mechanism to perform the first, second and third states, the limiting mechanism in the strip groove is at different heights, which is used to drive the position of the placement stage to move closer to or further away from the detection port; the front top plate is installed in the inner cavity of the feeding frame and can move synchronously with the placement stage. The front top plate is used to abut one end of the material to be tested.

[0014] In one feasible implementation, the feeding mechanism further includes an auxiliary groove and a top auxiliary component. The top of the feeding frame is an arc-shaped structure with the middle concave upward. The auxiliary groove is opened on the arc-shaped structure on both sides of the feed port. The top auxiliary component is movably disposed inside the auxiliary groove and is used to abut against the test material, so that the test material with a non-planar top tends to move in the horizontal direction.

[0015] In one feasible embodiment, the placement stage further includes: a substrate and a placement plate, the placement plate being fixedly disposed on the top of the substrate, the top end face of the placement plate having a plurality of limiting protrusions symmetrically distributed in the front-back or left-right direction, the placement plate being an inflatable material, the top end face of the placement plate being horizontal in the fully inflated state, and its horizontal plane corresponding to the position of the detection port; auxiliary rollers, two auxiliary rollers being rotatably disposed on the left and right sides of the bottom middle of the substrate, the positions of the auxiliary rollers corresponding to the positions of the strip groove and the limiting mechanism; an inflation port, the inflation port being fixedly disposed on the bottom end of the substrate, the inflation port having a valve, the inflation port being connected to the inner cavity between the substrate and the placement plate; and multiple limiting posts, the limiting posts being fixedly disposed on the bottom end of the substrate and movably penetrating through the bottom end of the feeding frame.

[0017] In one feasible implementation, the limiting mechanism includes an elastic support and a fixed support. The two ends of the two elastic supports and the fixed support extend to the electric push rod and the feeding mechanism in the first state, respectively. The section of the elastic support located between the first and second states of the feeding mechanism is a curved section, and the bending direction is upward from outside the machine body to inside the machine body.

[0018] The second aspect of this application provides a LIBS detection and analysis system for a multi-morphological material feeding structure, comprising: the multi-morphological material feeding structure as described in the first aspect.

[0019] This application provides a multi-form material feeding structure and a LIBS detection and analysis system, integrating an innovative feeding mechanism and LIBS detection technology into a composite system. This system can adapt to and handle various material forms, including fixed, powder, granular, or irregularly shaped materials. The feeding structure consists of a main body, a detector, a grinding mechanism, a feed inlet, a feeding mechanism, and a limiting mechanism. During operation, the material first enters the system through the feed inlet, then is fed by the feeding mechanism to the grinding mechanism for surface treatment.

Detailed Implementation

[0033] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0034] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0035] The main challenge facing existing LIBS analysis systems is their poor adaptability to materials of various shapes. Traditional transmission grinding equipment and handheld LIBS devices typically lack pre-processing capabilities for materials of multiple shapes, which limits the application range and efficiency of the testing equipment. This is especially true when dealing with non-standard shaped materials such as columnar, polygonal, or powdery materials, where existing equipment often fails to provide effective support. Furthermore, due to the lack of flexible and adaptable feeding mechanisms, existing testing equipment cannot effectively adjust the relative position between the material and the testing equipment, which may affect the accuracy and efficiency of the testing in some cases. Therefore, existing technologies face significant limitations when processing materials of multiple shapes, making it difficult to provide a technical solution for detecting multiple materials perpendicularly at the optimal angle. This may lead to low analytical efficiency or inaccurate results in practical applications.

[0036] Therefore, this application provides a multi-form material feeding structure and a LIBS detection and analysis system, the main purpose of which is to solve the problem of difficulty in providing a technical solution for detecting multiple materials vertically at the optimal angle.

[0037] Please see Figures 1-12 As shown, a first aspect of this application provides a multi-form material feeding structure, including: a body 1, a detector 2, a grinding mechanism 3, a feed inlet 4, a feeding mechanism 6, and a limiting mechanism 9. The detector 2 is fixedly mounted on the body 1. The body 1 includes a feed inlet 4, on which a buckle 5 is detachably mounted. The grinding mechanism 3 is fixedly mounted on the top of the body 1, with its grinding end located between the detector 2 and the feed inlet 4. The feeding mechanism 6 is movably mounted in the inner cavity of the body 1. In a first state, the feeding mechanism 6 is located outside the body 1. In a second state, the feeding mechanism 6 is located below the grinding mechanism 3. In a third state, the feeding mechanism 6 is located below the detector 2. The limiting mechanism 9 is fixedly mounted in the inner cavity of the body 1. One end of the limiting mechanism 9 extends into the feeding mechanism 6 in the first state, and the middle part of the limiting mechanism 9 passes through the detector 2 and the grinding mechanism 3.

[0038] The multi-morphological material feeding structure provided in this embodiment aims to improve the efficiency and adaptability of the LIBS detection and analysis system. The overall structure consists of a body 1, a detector 2, a grinding mechanism 3, a feed inlet 4, a feeding mechanism 6, and a limiting mechanism 9. Specifically, the body 1 serves as the frame of the entire device, providing stable support and device space. The detector 2 is fixed on the body 1 and is responsible for material analysis and data acquisition. The feed inlet 4 is located on the body 1 for material input. The grinding mechanism 3 is located at the top of the body 1, with its grinding end positioned between the detector 2 and the feed inlet 4. It is used to grind the material surface to ensure the flatness and uniformity of the test sample surface, thereby improving detection accuracy. The design of the feeding mechanism 6 is crucial. It not only transports the material to the detection area but also adjusts its position according to the material's shape. In its first state, the feeding mechanism 6 is located on the outside of the body 1 for easy access. Material loading; in the second state, the feeding mechanism 6 is positioned below the grinding mechanism 3 to provide for the grinding process and to acquire the ground material; in the third state, the feeding mechanism 6 is positioned below the detector 2, ready for LIBS analysis. The limiting mechanism 9 plays a crucial coordinating and positioning role throughout the process, ensuring the accurate position of the feeding mechanism 6 in different states. One end of the limiting mechanism 9 is connected to the feeding mechanism 6 in the first state, and the middle part passes through the detector 2 and the grinding mechanism 3, thus maintaining the coordination and precise alignment of each component throughout the operation. This makes the entire LIBS detection and analysis system more flexible and efficient in handling materials of various shapes. The design of the feeding mechanism 6 and the limiting mechanism 9 allows the equipment to adapt to materials of different shapes and sizes, thereby greatly expanding its application range. At the same time, the integration of the grinding mechanism 3 ensures appropriate treatment of the material surface and improves the accuracy of the detection.

[0039] like Figures 2 to 4 As shown, in some examples, the inner cavity of the machine body 1 further includes a slide rail 8 and an electric push rod 7. The electric push rod 7 is horizontally placed in the inner cavity of the machine body 1 and corresponds to the position of the feeding mechanism 6. A set of slide rails 8 is provided in the inner cavity of the machine body 1 below the electric push rod 7. The slide rails 8 are used for the feeding mechanism 6 to switch between the first state, the second state and the third state. The limiting mechanism 9 is arranged above the slide rails 8.

[0040] In this example, a multi-form material feeding structure is provided. The inner cavity of the machine body 1 integrates a slide rail 8 and an electric push rod 7, optimizing the dynamic adjustment and positioning of the feeding mechanism 6. The electric push rod 7 is positioned horizontally within the inner cavity of the machine body 1, corresponding to the position of the feeding mechanism 6, and drives the feeding mechanism 6 to switch between different states. The movement directly determines the position and state of the feeding mechanism 6, thus affecting the entire material processing and inspection process. The slide rail 8 is located within the inner cavity of the machine body 1 below the electric push rod 7, designed to guide and stabilize the movement of the feeding mechanism 6. Through these slide rails 8, the feeding mechanism 6 can smoothly switch between the first state (outside the machine body 1, facilitating material loading), the second state (below the grinding mechanism 3, for grinding), and the third state (below the detector 2, for material analysis). The presence of the slide rail 8 not only ensures… The feeding mechanism 6 operates smoothly, and the overall system reliability and efficiency are improved. The limiting mechanism 9 is arranged above the slide rail 8, providing important support for the precise positioning of the feeding mechanism 6 in different states. It helps ensure that the feeding mechanism 6 can accurately align to the required position in each state, whether it is receiving the material to be tested, feeding the material into the grinding mechanism 3 for surface treatment, or finally placing it under the detector 2 for analysis. The combination of the electric push rod 7 and the slide rail 8 provides a flexible and reliable mechanical drive system, allowing the feeding mechanism 6 to switch states quickly and smoothly. The limiting mechanism 9 ensures the accuracy of material height control in this process, which is suitable for materials of various heights. The setup in this example improves the system's ability to handle materials of various shapes and also optimizes the overall efficiency and accuracy of LIBS detection and analysis.

[0041] like Figure 3 , Figure 4 , Figure 7 , Figure 10 and Figure 11 As shown, in some examples, the polishing mechanism 3 further includes: a short-distance propulsion component 31, a housing 32, and a polishing component 33. The short-distance propulsion component 31 is fixedly mounted on the top of the body 1; the housing 32 is fixedly mounted in the inner cavity of the short-distance propulsion component 31 and is fixedly connected to the lower part of the short-distance propulsion component 31; the polishing component 33 is movably mounted in the inner cavity of the housing 32 in the vertical direction, and the top of the polishing component 33 is connected to the drive end of the short-distance propulsion component 31.

[0042] In this multi-form material feeding structure, the grinding mechanism 3 is used for the pretreatment of unqualified materials, such as those with uneven surfaces or impurities that are difficult to clean. The grinding mechanism 3 consists of a short-distance propulsion component 31, a housing 32, and a grinding component 33. The short-distance propulsion component 31 is fixedly mounted on the top of the machine body 1. The main function of the short-distance propulsion component 31 is to provide a power source for precise control, used to adjust the position and pressure of the grinding component 33 to adapt to materials of different thicknesses and hardnesses. The housing 32 is fixed in the inner cavity of the short-distance propulsion component 31 and is connected to the short-distance propulsion component 31 at its bottom, providing a stable outer shell and protective layer for the grinding component 33. It also assists in guiding the vertical movement of the grinding component 33. The grinding component 33 can move vertically in the inner cavity of the housing 32. Its top end is connected to the drive end of the short-distance propulsion component 31, allowing the grinding component 33 to move precisely vertically according to the characteristics of the material being processed (such as size, shape, and hardness), thereby achieving uniform and efficient grinding of the material surface.

[0043] Therefore, the grinding mechanism 3 provided in this example, by precisely controlling the position of the grinding component 33, allows the system to adapt to materials of various shapes, including samples with irregular shapes or special sizes. The high-precision motion control of the grinding mechanism 3 ensures uniform treatment of the material surface, which is crucial for subsequent LIBS testing, as the uniformity of the surface directly affects the accuracy of the test, thus ensuring the efficiency and accuracy of the testing process.

[0044] like Figure 12 As shown, in some examples, the grinding assembly 33 further includes: a grinding device 331, a drive unit 332, a drive roller 333, and a grinding belt 334; the grinding device 331 is fixedly mounted on the housing 32, the bottom of the grinding device 331 is the grinding end, the grinding end corresponds to the top end face of the feeding mechanism 6, and the drive unit 332 is provided on the side of the grinding device 331; two drive rollers 333 are arranged in parallel in the rectangular opening at the bottom end of the grinding device 331, the bottom end of the drive roller 333 is located outside the bottom end of the grinding device 331, and a grinding belt 334 is also sleeved on the outer wall of the drive roller 333, the grinding belt 334 is used to grind the surface of the test material 10 arranged in the feeding structure.

[0045] In the multi-form material feeding structure provided in this example, the grinding assembly 33 includes a grinding device 331, a drive unit 332, a drive roller 333, and a grinding belt 334, which together ensure effective and uniform grinding of the material surface. The grinding device 331 is fixedly mounted on the housing 32, and its bottom is designed as a grinding end for direct contact and processing of the material surface. The position of this grinding end corresponds to the top end face of the feeding mechanism 6, ensuring precise alignment when the material is conveyed from the feeding mechanism 6 to the grinding area. The drive unit 332 is located on... The side of the grinding equipment 331 is responsible for driving the operation of the entire grinding assembly 33. The drive roller 333 is arranged parallel to the rectangular opening at the bottom of the grinding equipment 331 and is located on the outside of the bottom of the grinding equipment 331. The grinding belt 334 is sleeved on the outer wall of the drive roller 333 and performs the grinding operation. When the material passes through the grinding equipment 331, the grinding belt 334 grinds its surface evenly and continuously to make it flat, so as to remove any uneven or irregular parts, thereby preparing an ideal surface condition for LIBS inspection.

[0046] Therefore, the grinding assembly 33 provided in this example ensures uniform surface treatment of the material through precisely aligned grinding ends and an efficient drive system, thereby improving the accuracy of LIBS analysis. This configuration allows the system to flexibly handle materials of different shapes and hardnesses, optimizing the performance and applicability of the entire LIBS testing system.

[0047] like Figures 2 to 10 As shown, in some examples, the feeding mechanism 6 further includes: a feeding frame 61, an upper top plate 62, a detection port 63, a strip groove 64, a placement platform 65, and a front top plate 68. The feeding frame 61 is fixedly connected to the drive end of the electric push rod 7. The upper top plate 62 is provided at the top of the feeding frame 61. An upwardly angled opening is provided on the front side of the upper top plate 62 for workers to place the material to be tested. A rectangular detection port 63 is provided in the middle of the upper top plate 62. The placement platform 65 is movably placed in the inner cavity of the feeding frame 61. The top end face of the placement platform 65 is used for... The material to be tested 10 is placed in the groove 64; two grooves 64 are vertically opened on both sides of the connection position between the feeding frame 61 and the output end of the electric push rod 7. A limiting mechanism 9 moves through the groove 64. When the electric push rod 7 drives the feeding mechanism 6 to perform the first state, the second state and the third state, the limiting mechanism 9 in the groove 64 is at different heights, which is used to drive the position of the placement table 65 to move in the direction closer to or away from the detection port 63; the front top plate 68 can be moved synchronously with the placement table 65 in the inner cavity of the feeding frame 61. The front top plate 68 is used to abut one end of the material to be tested 10.

[0048] In the multi-form material feeding structure provided in this embodiment, the feeding mechanism 6 is designed to ensure the correct delivery and positioning of the material. The feeding mechanism 6 consists of a feeding frame 61, an upper top plate 62, a detection port 63, a strip groove 64, a placement platform 65, and a front top plate 68, which together ensure the effective processing and transmission of the material. The feeding frame 61 is fixedly connected to the front drive end of the electric push rod 7, serving as the main support for the entire feeding mechanism 6. The upper top plate 62 is located at the top of the feeding frame 61, with an upwardly angled opening on the front side to facilitate the placement of the material to be tested by the operator. The rectangular detection port 63 in the middle allows the testing equipment to analyze the material placed on the placement platform 65. The placement platform 65 is movably installed in the inner cavity of the feeding frame 61, and its top end face is used to support and position the material to be tested 10. The strip groove 64 is vertically opened at the connection between the feeding frame 61 and the output end of the electric push rod 7. On both sides of the receiving position, the internal movement is connected by a limiting mechanism 9. The electric push rod 7 drives the feeding mechanism 6 to switch between the first state (material loading), the second state (grinding), and the third state (inspection and analysis). The height change of the limiting mechanism 9 in the strip groove 64 in different states is used to control the movement of the placement stage 65 in the direction of approaching or moving away from the detection port 63. The front top plate 68 can be movably placed in the inner cavity of the feeding frame 61 in the same direction as the placement stage 65 to abut one end of the material 10 to be tested, ensuring the stability and correct positioning of the material during the processing and reducing wear on the feeding frame 61. Therefore, the feeding mechanism 6 provided in this example ensures the accurate movement and positioning of the material throughout the process, ensures the stability during grinding and inspection, optimizes the efficiency of the entire LIBS inspection and analysis system, and shows significant adaptability, especially in the processing of multi-form materials.

[0049] like Figures 7-9 As shown, in some examples, the feeding mechanism 6 further includes an auxiliary groove 66 and a top auxiliary component 67. The top of the feeding frame 61 is an arc-shaped structure with the middle concave upward. The auxiliary groove 66 is opened on the arc-shaped structure on the front and rear sides of the feeding port 4. The top auxiliary component 67 is movably installed inside the auxiliary groove 66 to abut against the test material 10, so that the test material 10 with a non-planar top tends to move in the horizontal direction.

[0050] In this example, the feeding mechanism 6 ensures the correct delivery and positioning of materials. The feeding mechanism 6 consists of a feeding frame 61, an upper top plate 62, a detection port 63, a strip groove 64, a placement platform 65, and a front top plate 68, ensuring efficient material handling and transmission. Specifically, the feeding frame 61 is fixedly connected to the front drive end of the electric push rod 7, serving as the main support for the entire feeding mechanism 6. The upper top plate 62 is located at the top of the feeding frame 61, with an upwardly angled opening on the front side for easy placement of the material to be tested by the operator. The rectangular detection port 63 in the middle allows the testing equipment to analyze the material placed on the placement platform 65. The placement platform 65 is movably installed within the inner cavity of the feeding frame 61, and its top... The end face is used to support and position the material to be tested 10. The strip groove 64 is opened vertically on both sides of the connection position between the feed frame 61 and the output end of the electric push rod 7. The internal limit mechanism 9 moves through it. The electric push rod 7 drives the feed mechanism 6 to switch between the first state (material loading), the second state (grinding), and the third state (detection and analysis). The height change of the limit mechanism 9 in the strip groove 64 in different states is used to control the movement of the placement stage 65 in the direction close to or away from the detection port 63. The front top plate 68 can be moved synchronously with the placement stage 65 in the inner cavity of the feed frame 61 to abut one end of the material to be tested 10, ensuring the stability of the material during the processing and reducing wear.

[0051] The purpose of this embodiment is to ensure that the electric push rod 7 and the strip groove 64 work together to ensure smooth switching of the feeding mechanism 6 in different working states, while also ensuring accurate material movement throughout the process. The upper top plate 62 and the front top plate 68 facilitate the loading and fixing of materials, ensuring stability during grinding and inspection movements.

[0052] like Figure 5 , Figure 6 , Figure 8 and Figure 10As shown, in some examples, the placement stage 65 further includes: a substrate 651, a placement plate 652, limiting protrusions 653, an auxiliary roller 654, an inflation port 655, and limiting posts 656. The placement plate 652 is fixedly placed on the top of the substrate 651. Multiple limiting protrusions 653 are symmetrically distributed in the front-back or left-right directions on the top surface of the placement plate 652. The placement plate 652 is made of inflatable material, and in a fully inflated state, the top surface of the placement plate 652 is horizontal, and its horizontal plane is perpendicular to the detection port 63. The positions are corresponding; two auxiliary rollers 654 are rotatably arranged on the left and right sides of the bottom middle of the substrate 651, and the positions of the auxiliary rollers 654 correspond to the positions of the strip groove 64 and the limiting mechanism 9; the air inlet 655 is fixedly arranged at the bottom of the substrate 651, and a valve is provided on the air inlet 655. The air inlet 655 is connected to the inner cavity between the substrate 651 and the placement plate 652; the number of limiting posts 656 is multiple. The limiting posts 656 are fixedly arranged at the bottom of the substrate 651 and move through the bottom of the feeding frame 61.

[0053] In this multi-form material feeding structure, the placement platform 65 is designed to handle irregularly shaped or non-standard materials. The placement platform 65 includes key components such as a base plate 651, a placement plate 652, limiting protrusions 653, auxiliary rollers 654, an inflation port 655, and limiting posts 656, which together ensure the correct handling and transmission of irregularly shaped materials. The placement plate 652, as a soft inflatable material, is fixedly placed on the top of the base plate 651. Multiple limiting protrusions 653, symmetrically distributed in the front-back or left-right directions, are provided on the top surface of the placement plate 652. These limiting protrusions 653 help to stably place irregularly shaped materials or limit the movement of columnar materials, preventing them from rolling off. When inflated, the placement plate 652... The top end face is horizontal and corresponds to the position of the detection port 63 to ensure accurate positioning of the material during the detection process. The auxiliary roller 654 is rotatably mounted on the left and right sides of the bottom middle of the substrate 651, and its position corresponds to the strip groove 64 and the limiting mechanism 9. When the placement table 65 moves, the auxiliary roller 654 contacts the limiting mechanism 9 to achieve the lifting function. Especially when processing irregularly shaped materials, it provides an additional elastic support effect. The air inlet 655 is fixed to the bottom end of the substrate 651 and is equipped with a valve. It connects the inner cavity between the placement plate 652 and the substrate 651. By adjusting the air inlet 655, the shape and height of the placement plate 652 can be flexibly controlled to adapt to materials of different shapes.

[0054] When irregularly shaped materials are placed on the placement plate 652, the placement stage 65 moves upward, allowing the irregularly shaped tip of the material to contact the top auxiliary component 67, which is movably mounted on the top of the feeding frame 61. As the placement stage 65 continues to move, the tip of the irregularly shaped material gradually conforms to the inner wall of the feeding frame 61, making the tip face of the material approach a horizontal state. Since the placement plate 652 is a soft inflatable material, it allows the material to rotate as necessary to adjust and maximize the horizontality of the tip face of the irregularly shaped material. Therefore, the design of the placement stage 65 significantly improves the system's ability to handle irregularly shaped or non-standard materials, ensuring the correct positioning and stability of the material throughout the inspection process. The flexibility of the inflatable placement plate 652, combined with the coordination of the top auxiliary component 67, allows the system to adapt to materials of various shapes, especially when handling irregular shapes, maintaining the stability and proper positioning of the material.

[0055] like Figure 8 and Figure 9 As shown, in some examples, the top auxiliary component 67 further includes: a slider 671, which is slidably engaged in the auxiliary groove 66 towards both sides of the detection port 63; the bottom end of the slider 671 is provided with an abutment block 672 that protrudes inward from the inner wall of the top of the feed frame 61; the abutment block 672 is arranged at the end of the slider 671 away from the detection port 63; and the two sliders 671 located in the same auxiliary groove 66 are elastically connected by an elastic rope 673.

[0056] In this example, the top auxiliary component 67 plays a role in handling and positioning irregularly shaped or irregularly shaped materials in the multi-form material feeding structure. The top auxiliary component 67 consists of a slider 671, an abutment block 672, and an elastic rope 673 to adapt to materials of different shapes and provide stable support. The slider 671 can slide along the auxiliary groove 66, which is engaged with the inner side of the top of the feed frame 61. This design of the slider 671 allows it to slide along the feed frame 61 towards both sides of the detection port 63, thereby adapting to materials of different widths. The bottom end of the slider 671 has an inwardly protruding abutment block 672, which is located at the end of the slider 671 away from the detection port 63. The arrangement allows the material to contact its non-planar top. Thus, when the irregularly shaped material on the placement platform 65 is raised to conform to the inner wall, the abutment block 672 provides a counterforce, helping to adjust the top of the material to be as horizontal as possible. The elastic rope 673 connects two sliders 671 located in the same auxiliary groove 66, providing the necessary elasticity and tension to maintain a stable distance between the sliders 671, while also allowing a degree of flexibility to adapt to changes in material shape. This design allows the sliders 671 to move in a coordinated manner as the material shape changes, maintaining the stability and horizontality of the material top, thereby providing optimal preconditions for LIBS testing.

[0057] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in some examples, the limiting mechanism 9 further includes an elastic support 91 and a fixed support 92. The two ends of the elastic support 91 and the fixed support 92 extend to the electric push rod 7 and the feeding mechanism 6 in the first state, respectively. The section of the elastic support 91 located between the first and second states of the feeding mechanism 6 is a curved section, and the bending direction is upward from the outside of the machine body 1 to the inside of the machine body 1.

[0058] In this example, the limiting mechanism 9 ensures the precise positioning and stable operation of the feeding mechanism 6 in different states, smoothly lifting the test material 10 towards the detection port 63. The limiting mechanism 9 includes an elastic support 91 and a fixed support 92, which work together to maintain the correct position and stable movement of the feeding mechanism 6. The ends of the elastic support 91 and the fixed support 92 extend to the electric push rod 7 and the feeding mechanism 6, respectively. This arrangement allows the limiting mechanism 9 to provide stable support and guidance during the transition of the feeding mechanism 6 from the first state (outside the body 1, for material loading) to the second state (below the grinding mechanism 3, for material grinding). In particular, the presence of the elastic support 91 provides the necessary elasticity and flexibility for the movement of the feeding mechanism 6. The section of the elastic support 91 located between the first and second states of the feeding mechanism 6 is designed as a curved section, bending upwards from the outside of the body 1 to the inside of the body 1. This allows the elastic support 91 to lift the material 10 being tested when the feeding mechanism 6 moves, while maintaining sufficient elasticity to ensure the smooth operation of the grinding mechanism 3, which is a necessary condition for optimizing the efficiency and accuracy of LIBS testing and analysis.

[0059] The second aspect of this application provides a LIBS detection and analysis system for a multi-morphological material feeding structure, including the multi-morphological material feeding structure as described in the first aspect.

[0060] The LIBS detection and analysis system for multi-form material feeding structures provided in this application embodiment is a composite system integrating an advanced feeding mechanism and LIBS detection technology. It can adapt to and handle feeding structures for various forms of materials, including fixed, powder, granular, or irregularly shaped materials. This feeding structure consists of main components such as a body 1, a detector 2, a grinding mechanism 3, a feed inlet 4, a feeding mechanism 6, and a limiting mechanism 9. During the entire operation, the material first enters the system through the feed inlet 4, and is then fed by the feeding mechanism 6 to the grinding mechanism 3 for surface treatment. The treated material is then accurately delivered below the detector 2 for LIBS analysis. The system also includes an electric push rod 7 and a slide rail 8. The limiting protrusion 653, auxiliary roller 654, air inlet 655, limiting post 656, and top auxiliary component 67 are all designed to ensure smooth material transport and accurate positioning throughout the process. In particular, the design of the air-filled placement plate 652 and the top auxiliary component 67 enables the system to effectively adapt to and stabilize irregularly shaped materials. This LIBS detection and analysis system with its multi-form material feeding structure not only improves the adaptability to various material forms but also optimizes the efficiency and accuracy of the detection process. All components and mechanisms in the system are designed to provide stable and reliable material transport and ensure accurate positioning during the detection process, expanding its application potential in various industrial and research fields.
