Description

Technical Field

[0001] This utility model relates to the field of product testing, and in particular to an imaging device. Background Technology

[0002] With the development of automation, imaging equipment is now commonly used for automated inspection of product structures. However, for products with multi-layered structures, inspection using imaging equipment only after production is complete cannot determine whether the internal structure is up to standard. Therefore, each layer needs to be inspected separately after assembly, which leads to too many inspection steps, wasting a lot of time and space, and increasing the manufacturing cost of the production line.

[0003] X-ray imaging can detect the internal structure of a product, thus saving the step of layered imaging. The internal structure can be detected simply by irradiating the product with X-rays after it has been manufactured. However, this method cannot detect the external surface of the product, so it still requires two steps: X-ray detection and optical imaging, which is still relatively cumbersome and complex. Utility Model Content

[0004] The purpose of this invention is to provide an imaging device that can simultaneously detect the external surface and internal condition of a product.

The connecting portion is connected to the end of the limiting rod away from the sliding rod, passes around the side of the flat panel detector, and extends towards the middle of the side of the flat panel detector near the optical camera, forming a positioning end of the transverse portion. The longitudinal portion is connected to the positioning end of the transverse portion and is perpendicular to the transverse portion.

[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Please see Figure 1 The imaging device claimed in this utility model application includes a support plate 1, a flat panel detector 4, an X-ray source, and an optical camera 7. The support plate 1 is supported by a truss and its orientation is parallel to a reference plane. The rectangular flat panel detector 4 is supported by the support plate 1 and is positioned parallel to the reference plane. The X-ray source is parallel to the reference plane and its orientation is parallel to the flat panel detector 4. The X-ray source emits X-rays 101 toward the flat panel detector 4, and the X-rays 101 pass through the product located at the detection position. The optical camera 7 is connected to the flat panel detector 4 and is positioned between the flat panel detector 4 and the product. The optical camera 7 includes a light source 72 and an image sensor chip interconnected.

[0039] Please refer to the following examples for details.

[0040] Example 1:

[0041] Please see Figure 1 The imaging device shown in a preferred embodiment of this application includes an adjustable mechanism, a loading assembly, and an X-ray source. The X-ray source is fixedly mounted on a horizontal worktable. The loading assembly includes a stage and a transfer assembly. The stage carries the product to be inspected, and the transfer assembly drives the stage to move controllably in the horizontal direction to the inspection position. The adjustable mechanism includes a support plate 1, a flat panel detector 4, and an optical camera 7. Both the flat panel detector 4 and the optical camera 7 are mounted on the support plate 1. X-rays 101 emitted from the X-ray source pass through the product located at the inspection position and reach the flat panel detector 4, thereby generating a transmission image. The optical camera 7 includes a cylindrical housing 71, a light source 72, and an image sensor chip. The light source 72 is constructed in a ring shape and connected to the end of the housing 71 near the product. The image sensor chip is fixedly connected inside the housing 71 and parallel to the light source 72. Part of the illumination light emitted by the light source 72 towards the product located at the inspection position is reflected by the product and reaches the image sensor chip. The target surface of the image sensor chip receives the light and forms a surface image.

[0042] Please see Figure 1 and Figure 2 The adjustable mechanism also includes a leveling component, a first steering component 3, a displacement component, and a second steering component 6.

[0043] The leveling assembly is used to adjust the levelness of the support plate 1. The support plate 1 includes a support portion 11, a pushing portion 12, and a leveling portion 13. The support portion 11 is constructed in a rectangular strip shape, with both ends extending towards the same side to form a pushing portion 12 perpendicular to the support portion 11. The end of the pushing portion 12 away from the support portion 11 extends in a direction away from the support portion 11 to form a leveling portion 13 parallel to the support portion 11. Two leveling screw holes are formed on each of the two leveling portions 13, and the two leveling screw holes formed on the same leveling portion 13 are arranged in a direction parallel to the pushing portion 12. Four leveling bolts 21 pass through each leveling screw hole, and the end of the leveling bolt 21 away from its head is rotatably connected to a position at the same height as the truss. By rotating the head of the leveling bolt 21, the height of the four corners of the support plate 1 is adjusted, so that the support portion 11 of the support plate 1 remains level.

[0044] The first steering assembly 3 includes a base plate 31, a rotating shaft 32, and a plurality of first bolts 33. A cylindrical rotating shaft 32 is formed by a protrusion on the central surface of the base plate 31. A central shaft hole, fitted to the rotating shaft 32, is formed in the central part of the support portion 11 of the support plate 1, and the rotating shaft 32 is embedded in the central shaft hole. Sliding holes 111 are formed on both sides of the support portion 11 of the support plate 1. An arc-shaped hole 311 is provided on the base plate 31 at a position corresponding to the sliding hole 111. The arc-shaped hole 311 is constructed as an elongated arc-shaped hole coaxial with the rotating shaft 32 and is detachably connected to the sliding hole 111 and the arc-shaped hole 311 by bolts. Two first screw holes are formed on the pushing portion 12 of the support plate 1, respectively located on both sides of the central axis of the rotating shaft 32. The first bolts 33 fit into the first screw holes and pass through them, with their ends used to push the side of the base plate 31 to rotate the base plate 31. When the bolt connection is loose, the substrate 31 rotates along the pivot 32 relative to the support portion 11 of the support plate 1. By adjusting the first bolt 33, the angle of the substrate 31 relative to the support plate 1 can be finely adjusted. When the setting direction of the rectangular flat panel detector 4 fixedly connected to the substrate 31 is parallel to the rectangular X-ray source, the bolt is tightened to fix the substrate 31 relative to the support plate 1, thus completing the adjustment of the flat panel detector 4.

[0045] The displacement assembly includes a support rod 51 supported on the flat panel detector 4, a transverse assembly 52 connecting the support rod 51 and the flat panel detector 4, and a longitudinal assembly 53 connecting the support rod 51 and the optical camera 7.

[0046] The support rod 51 includes a transverse portion 511, a connecting portion 515, and a longitudinal portion 516 that are interconnected. The top surface of the flat panel detector 4 is fixedly connected to the substrate 31, and the transverse portion 511 is supported on the top surface of the flat panel detector 4 without interfering with the substrate 31. It includes a sliding rod 512 and a limiting rod 513. The sliding rod 512 is arranged parallel to one side of the flat panel detector 4, and two limiting rods 513 are perpendicularly connected to its two ends. One end of the limiting rod 513 is connected to the sliding rod 512, and the other end extends away from the substrate 31. A transverse elongated hole 514 parallel to the limiting rod 513 is provided on the limiting rod 513, and multiple limiting holes corresponding to the transverse elongated hole 514 are provided on the flat panel detector 4. The transverse elongated hole 514 and the limiting holes are detachably connected. The connecting part 515 is connected to the end of the limiting rod 513 away from the sliding rod 512, passes around the side of the flat panel detector 4, and extends toward the middle of the side of the flat panel detector 4 near the optical camera 7 to form the positioning end of the horizontal part 511. The vertical part 516 is connected to the positioning end of the horizontal part 511 and is perpendicular to the horizontal part 511.

[0047] The lateral assembly 52 includes an adjustment block 521 fixedly connected to the top surface of the flat panel detector 4. The adjustment block 521 has a screw hole parallel to the limiting rod 513, through which a lateral bolt 522, which mates with the adjustment block 521, passes. The adjustment block 521 is positioned between the two limiting rods 513. The end of the lateral bolt 522 furthest from its head is rotatably connected to the side of the sliding rod 512, causing the sliding rod 512 to move closer to or away from the substrate 31. When the position of the sliding rod 512 is fixed, a reinforcing structure connecting the lateral elongated hole 514 and the limiting hole prevents the supporting rod 51 from falling off.

[0048] The longitudinal component 53 includes two rows of positioning holes 531 arranged in a direction parallel to the longitudinal portion 516, and a lifting plate 532 detachably connected to the longitudinal portion 516. The lifting plate 532 is provided with a second elongated hole parallel to the longitudinal portion 516. The second elongated hole cooperates with the positioning holes 531 and is fastened to any one of the positioning holes 531 by longitudinal bolts 534. The housing 71 of the optical camera 7 is supported on the lifting plate 532.

[0049] A horizontally arranged rotating base 61 and a reinforcing plate 62 are fixedly connected to the side of the lifting plate 532. The structure of the second rotating assembly is similar to that of the first steering assembly 3, and it is connected between the rotating base 61 of the lifting plate 532 and the top of the housing 71 of the optical camera 7, so that the housing 71 of the optical camera 7 can be controllably rotated and connected to the rotating base 61 along its central axis. The setting angle of the optical camera 7 is finely adjusted by the second bolt 63, thereby facilitating the adjustment of the setting direction of the target surface of the image sensor chip to be parallel to the flat panel detector 4. The reinforcing plate 62 is set below the rotating base 61 at a position corresponding to the bottom of the housing 71, and is used to assist in supporting the optical camera 7.

[0050] In this embodiment, the flat panel detector 4 and the image sensing chip are electrically connected to an external display, which displays the images detected by the flat panel detector 4 and the image sensing chip. When adjusting the adjustable mechanism, the shape and position of the surface image and the transmitted image displayed on the display are used to determine the adjustment effect of the adjustable mechanism, and the adjustment is performed in conjunction with the image on the display to obtain a high-precision image.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
