TECHNICAL FIELD
[0001] The application belongs to the technical field of product detection, and particularly relates to a planar CT and DR detection platform. BACKGROUND
[0002] In the field of modern industrial detection, planar CT (Computed Tomography) and DR (Digital Radiography) detection technologies have become important means for product quality evaluation due to their non-destructive and high-resolution advantages. With the continuous improvement of industrial automation, higher requirements are put forward for the compatibility, precision and convenience of detection platforms. Most existing devices only have single DR detection or CT detection functions, and few products effectively integrate both into the same platform, resulting in the need for users to purchase multiple devices when facing different detection needs, causing increased costs and wasted space. Therefore, detection platforms with better compatibility and flexibility are needed. In addition, the structural design of the detection platform directly affects the detection accuracy and operation efficiency, and high-precision mechanical structures and convenient installation and debugging methods are key to ensuring the reliability of detection results.
[0003] Currently, the most similar detection platform to the present application on the market is the traditional planar CT and DR detection device. These devices usually adopt fixed structural design and have certain limitations in compatibility and structural flexibility. Specifically, in terms of compatibility, most devices only focus on online or offline single mode applications and cannot be upgraded and switched between the two modes. From the perspective of function implementation, existing devices either focus on DR detection, using X-ray to penetrate objects and form images on a flat panel detector to obtain two-dimensional projection images, or focus on CT detection, using an X-ray source and detector rotating around the object to collect multiple sets of data for three-dimensional reconstruction. However, devices that combine the advantages of fast two-dimensional imaging of DR and three-dimensional detail detection of CT are extremely rare, making it difficult for users to complete comprehensive and efficient detection work on a single device. In terms of structural design, the base of traditional detection platforms is usually made of metal or ordinary stone materials, which lacks stability in precision; the detector module mechanism and light source module mechanism are usually designed with two axes or a single axis, limiting the range and precision of movement; the machine cover and internal mechanism are usually integrated, requiring the installation of components such as detectors, light sources, and object tables one by one inside the machine cover, which is a tedious process and makes it difficult to perform high-precision marking and calibration operations. In terms of detection accuracy, the detectors used in traditional devices have limited precision and insufficient magnification, making it difficult to clearly detect subtle defects in products; the image processing system usually uses general algorithms, resulting in unsatisfactory image contrast enhancement and affecting the accuracy of defect identification. If a planar CT and DR detection platform with simple structure, accurate positioning, and the ability to simultaneously realize CT and DR detection, as well as easy switching between online and offline modes, can be designed, the above problems can be solved.

DETAILED DESCRIPTION
[0017] As Figures 1 to 5As shown, in this embodiment, the present invention includes a machine base 1, a movable platform module 2, and a three-axis detection component 3. The three-axis detection component 3 includes a three-axis movable module 4 and a detection module 5. The three-axis movable module 4 is disposed on the upper end of the machine base 1, and the detection module 5 is connected to the movable end of the three-axis movable module 4. The movable platform module 2 is disposed on one side of the machine base 1, and the three-axis movable module 4 drives the detection module 5 to cooperate with the product on the movable platform module 2. Therefore, the high-precision motion system composed of the machine base 1, the three-axis detection component 3, the three-axis light source component 9, and the movable platform module 2 in this application ensures positional accuracy and motion stability during the detection process. The combination of a large-size high-precision detector, a high-magnification optical system, and a self-developed image processing algorithm forms a complete high-performance detection and image optimization scheme, significantly improving the quality of the detected images and the defect identification capability. Simultaneously, differentiated image processing strategies have been developed for the different characteristics of DR and CT detection images, further enhancing the accuracy and reliability of the detection results.
[0018] like Figure 3 and Figure 4 As shown, in this embodiment, the three-axis movement module 4 includes a linear detection module 41 for the X-axis, a linear detection module 42 for the Y-axis, and a linear detection module 43 for the Z-axis. The linear detection module 41 for the X-axis is disposed on the upper end of the machine tool 1. The linear detection module 42 for the Y-axis is connected to the movable end of the linear detection module 41 for the X-axis. The linear detection module 43 for the Z-axis is connected to the movable end of the linear detection module 42 for the Y-axis. The detection module 5 is connected to the movable end of the linear detection module 43 for the Z-axis. Therefore, the linear detection modules 41, 42, and 43 for the X-axis drive the detection module 5 to move precisely in the X, Y, and Z axes, respectively.
[0019] like Figure 3 and Figure 5 As shown, in this embodiment, the detection module 5 includes a detection bracket 51, a CT detection module 52, and a DR detection module 53. The CT detection module 52 and the DR detection module 53 are respectively disposed on both sides of the lower end face of the detection bracket 51. The detection bracket 51 cooperates with the movable end of the Z-axis linear module 43. Therefore, the CT detection module 52 and the DR detection module 53 can be compatible with the detection of different products within a certain size range, exhibiting strong compatibility.
[0020] like Figure 2 , Figure 3 as well as Figure 6As shown, in this embodiment, the mobile platform module 2 includes a platform 21 and a moving slide rail 22. The platform 21 slides with the outer center of the machine base 1 via the moving slide rail 22 and the transverse cylinder module. Therefore, while the platform 21 enables unidirectional loading and unloading, it can also change the transmission direction by using a conveyor belt system to transport products from both sides of the machine base 1, thus achieving a rapid transition from offline loading and inspection to online loading and inspection.
[0021] like Figure 3 As shown, in this embodiment, a plurality of sensors 6 are provided on one side of the platform 21, and the sensors 6 cooperate with the products on the platform 21. Therefore, the sensors 6 can detect the presence or absence of products on the platform 21, avoiding the detection of no material.
[0022] like Figure 3 As shown, in this embodiment, a positioning detector 7 is provided on the side of the detection bracket 51 near the mobile platform module 2. The positioning detector 7 engages with the product on the mobile platform module 2. Therefore, the positioning detector 7 can identify the precise position of the product on the platform 21 and control the triaxial detection assembly 3 to move into position for CR and DR detection.
[0023] like Figure 2 and Figure 3 As shown, in this embodiment, a lifting blocking module 8 is provided at the bottom of the side of the machine base 1 corresponding to the mobile platform module 2. The lifting blocking module 8 includes a blocking plate 81 and a lifting cylinder 82. The blocking plate 81 is slidably engaged with one side of the machine base 1 via several lifting slide rails 83. The lifting cylinder 82 is located on one side of the machine base 1 and drives the blocking plate 81 to engage with the mobile platform module 2. Therefore, when the mobile platform module 2 is in the detection state, the blocking plate 81 rises to prevent the platform 21 from sliding out. When the mobile platform module 2 is configured for online detection, the lifting blocking module 8 can be respectively located at both ends of the mobile platform module 2 to prevent new products from flowing into the external line and products being detected from flowing out of the mobile platform module 2 during the detection process.
[0024] like Figure 3 and Figure 4As shown, in this embodiment, a three-axis light source assembly 9 is provided at the lower end of the machine base 1. The three-axis light source assembly 9 includes a light source X-axis linear module 91, a light source Y-axis linear module 92, a light source Z-axis linear module 93, and a light source module 94. The light source X-axis linear module 91 is located at the lower end of the machine base 1. The light source Y-axis linear module 92 is connected to the movable end of the light source X-axis linear module 91. The light source Z-axis linear module 93 is connected to the movable end of the light source Y-axis linear module 92. The light source module 94 is connected to the movable end of the light source Z-axis linear module 93 and cooperates with the product on the moving platform module 2. Therefore, the three-axis light source assembly 9 is configured to move in three axes, providing the optimal angle of light source for the inspection station.
[0025] like Figure 1 As shown, in this embodiment, a machine cover 10 is provided outside the machine base 1, and the machine cover 10 is provided with a loading safety door 11. Therefore, the machine cover 10 provides an independent and safe testing environment.
[0026] like Figure 1 As shown, in this embodiment, the machine cover 10 is equipped with an operation module 12. Therefore, the operation module 12 can control the start / stop and state switching of the equipment.
[0027] The working principle of this invention is as follows: Before the equipment is started, several sensors 6 identify the products in the platform 21. When there are no products on the platform 21, the platform 21 is pushed out from the middle of the machine 1. A person or an external robot places the product on the platform 21, and the platform 21 enters the detection position in the middle of the machine 1. The positioning detector 7 detects the position of the product and drives the three-axis moving module 4 to move. The relative height between the detection module 5 and the product is adjusted, and the three-axis light source assembly 9 moves synchronously. The detection module 5 starts to perform CT or DR detection. After the detection is completed, all components are reset, the platform 21 is pushed out, and the product to be detected is replaced. The above steps are repeated to realize CT and DR detection of the product.
[0028] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
