Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to an X-ray detection device with adjustable detection distance. Background Technology

[0002] In existing X-ray inspection equipment, for waterproofing purposes, the X-ray detector and X-ray emitter are usually installed in the same sealed enclosure. The X-ray receiver is installed at the bottom of the enclosure, and the X-ray emitter is installed at the top.

[0003] Because the dimensions of the enclosure are fixed, the distance between the X-ray detector and the X-ray emitter is constrained, and their relative positions remain constant. This design often results in less than ideal performance when X-ray inspection equipment is used to inspect low-density products.

[0004] In real-world applications, when inspecting certain products, X-ray detectors need to be placed closer to the X-ray detector and the X-ray emitter to achieve better inspection performance.

[0005] However, because the distance between the X-ray emitter and the X-ray detector is fixed in the existing structure, the detection distance cannot be shortened, which affects the detection effect of some products.

[0006] In view of this, the inventors of this application have designed an X-ray detection device with adjustable detection distance in order to overcome the above-mentioned technical problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the defect in the prior art where the distance between the X-ray emitter and the X-ray detector is fixed and cannot be shortened, thus affecting the product detection effect, and to provide an X-ray detection device with adjustable detection distance.

[0012] According to one embodiment of the present invention, multiple rows of mounting holes are provided on the two side walls of the detection device housing. The mounting holes are arranged vertically at intervals, and the mounting part is fixedly connected to the corresponding mounting holes by fasteners.

[0013] According to one embodiment of the present invention, the conveying device includes: a fixed bracket with an internal accommodating unit, at least two fixed guide rails, an X-ray detector assembly, and a sealing plate. The lower part of the accommodating unit has an open structure for accommodating the X-ray detector assembly.

[0014] The fixed guide rails are fixed at intervals to the top of the receiving unit, and the X-ray detector assembly is installed between the fixed guide rails; the sealing plate is detachably fixed to the bottom of the receiving unit to seal the lower opening of the receiving unit.

[0015] According to one embodiment of the present invention, a downwardly extending bent portion is provided on one side of the conveying device, the side facing the housing of the detection device, a positioning groove is provided on the bent portion, and multiple rows of positioning holes arranged vertically at intervals are provided on the front side of the housing of the detection device, and the positioning groove is fixed to the corresponding positioning hole by a positioning member.

[0019] According to one embodiment of the present invention, the fixed guide rail is fixed to the top of the receiving unit by a fastener.

[0020] The positive and progressive effects of this utility model are as follows:

[0021] This utility model relates to an X-ray detection device with adjustable detection distance. It separates the X-ray detector from the housing of the detection device, making it an independent unit. This not only allows the height of the X-ray detector to be adjusted, improving the detection performance of X-rays, but also allows this unit to be modularized.

[0055] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0056] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0057] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0058] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0059] like Figures 1 to 6 As shown, this utility model discloses an X-ray detection device with adjustable detection distance, including a detection device housing 10, an X-ray emitting unit 20, and a conveying device 30 equipped with an X-ray detector. The X-ray emitting unit 20 includes an X-ray emitter located within the detection device housing 10. The X-ray emitting unit 20 is mounted on the upper part of the detection device housing 10, and the conveying device 30 is detachably mounted on the detection device housing 10, located below the X-ray emitting unit 20, allowing the distance between the conveying device 30 and the X-ray generator 20 to be adjusted vertically.

[0060] Preferably, such as Figure 6 and Figure 7 As shown, at least one mounting portion 40 is provided on one side of the conveying device 30, facing the detection device housing 10, and is connected to the detection device housing 10 via the mounting portion 40. For example, the mounting portion 40 can preferably be L-shaped. This structure facilitates the installation and connection of the conveying device.

[0061] Accordingly, multiple rows of mounting holes 11 are provided on both side walls of the detection device housing 10. The mounting holes 11 are arranged vertically at intervals, and the mounting part 40 is fixedly connected to the corresponding mounting hole 11 by fasteners (e.g., fixing screws). In this way, the distance between the conveying device 30 and the X-ray emitting part 20 can be adjusted by adjusting the installation position of the conveying device 30.

[0062] Typically, when inspecting certain products, X-ray detectors require the X-ray detector and the X-ray emitter within the X-ray emitting unit 20 to be closer together to achieve better inspection performance. However, since the distance between the X-ray emitter and the X-ray detector is often fixed, the inspection distance cannot be shortened, thus affecting the inspection results for some products.

[0063] Therefore, this application separates the X-ray detector and installs it inside the delivery device to form an independent unit. By adjusting the installation position, the distance between the X-ray detector and the X-ray emitter can be adjusted.

[0064] If the density of certain products is low and the detection effect is not ideal, the user can adjust the height of the entire independent unit (i.e., the delivery device containing the X-ray detector), move it upward to the corresponding position of the multiple rows of mounting holes 11 above, and lock it in place, thereby adapting to the detection application scenarios of certain special products.

[0065] If the height of certain products is too high and exceeds the current detection height, the user can adjust the height of the entire independent unit (i.e., the delivery device containing the X-ray detector) and move it down to the corresponding position of the multiple rows of mounting holes 11 below, and lock it in place, thereby adapting to the detection application scenarios of certain special products.

[0066] like Figure 7 and Figure 8 As shown, the conveying device 30 includes a fixed bracket 31, at least two fixed guide rails 32, an X-ray detector assembly 33, and a sealing plate 34. The fixed bracket 31 houses a receiving unit A, and its lower part is an open structure for accommodating the X-ray detector assembly 33. The fixed guide rails 32 are fixed to the top of the receiving unit A at intervals, i.e., fixed to the inner top wall surface of the receiving unit A. For example, the fixed guide rails 32 can be fixed to the top of the receiving unit A using fasteners 35 (such as welding screws).

[0067] X-ray detector assembly 33 is mounted between fixed guide rails 32. In this way, X-ray detector assembly 31 can be installed into the lower part of the open structure of housing unit A, and the size of housing unit A can be controlled to a minimum.

[0068] After the X-ray detector assembly 33 is installed in the receiving unit A, the sealing plate 34 is detachably fixed to the bottom of the fixing bracket 31 to seal the lower opening of the receiving unit A (e.g., Figure 5 and Figure 6 (As shown).

[0069] Through the above structural design, the size of the accommodating unit A can be effectively controlled, thereby maximizing the reduction of the overall thickness of the conveying device, for example, the overall thickness B of the conveying device (e.g., Figure 8 (As shown) is set to less than or equal to 80mm. For example, the overall thickness of the conveying device can be specifically set to values ​​such as 50mm, 55mm, 60mm, 70mm, and 80mm, all of which can achieve good thickness dimensions.

[0070] Preferably, the X-ray detector assembly 33 includes an X-ray detector 331 and a mounting plate 332. The X-ray detector 331 is mounted on the mounting plate 332, and both ends of the mounting plate 332 are respectively connected to corresponding fixed guide rails 32. For example, a slot 321 is provided on the fixed guide rail 32, and both ends of the mounting plate 332 are respectively inserted into the slot 321.

[0071] More preferably, a downwardly extending bent portion 311 is provided on one side of the receiving unit 31, the side facing the detection device housing 10, and a positioning slot 312 is formed on the bent portion 311. Multiple rows of vertically spaced positioning holes 12 (e.g., ...) are formed on the front of the detection device housing 10. Figure 4 As shown, a positioning element 13 is installed inside the positioning hole 12, and the positioning slot 312 is fixed to the corresponding positioning hole 12 by the positioning element 13 (for example, the positioning element 13 is stuck in the positioning slot 312). Here, the positioning slot 312 is preferably an elongated slot.

[0072] When the conveying device 30 is installed on the detection device housing 10 (e.g.) Figure 4 As shown, the initial position can be achieved by cooperating with the positioning slot 312 and the positioning component. Then, the final fixed position of the conveying device is achieved by the mounting part 110. Here, the detection device housing 10 is equipped with components such as an X-ray emitter, an electrical board, and sensors.

[0073] For example, during installation, one screw (i.e., positioning piece 13) can be screwed into the detection device housing 10 first, only about 6mm in. Then, the entire independent conveying device 30 is hung on the screw through the elongated slot in the middle. The remaining screws (i.e., positioning pieces 13) are then tightened all at once. This reduces the installation difficulty for assembly workers.

[0074] like Figure 8 As shown, the conveying device 30 also includes a driving roller 36, a driven roller 37, two support rollers 38, a motor 39, and a belt 50. The driving roller 36 is mounted at the output end of the fixed bracket 31, the driven roller 37 is mounted at the input end of the fixed bracket 31, and the support rollers 38 are mounted at the bottom of the fixed bracket 31, located on both sides of the X-ray detector assembly 33. The two support rollers 38 are respectively close to the driving roller 36 and the driven roller 37. The motor 39 can be mounted at the output end of the fixed bracket 31 and connected to the driving roller 36 to drive the driving roller 36 to rotate. Then, the driving roller 36 drives the driven roller 37 and the support rollers 38 to rotate together. The belt 50 is tensioned and wrapped around the driving roller 36, the driven roller 37, and the support rollers 38.

[0075] Before the sealing plate 34 is installed, the conveying device 30 can first fix the fixed guide rail 32, and then install the fixing plate 332 between the fixed guide rails 32. Finally, the sealing plate 34 is fixed to the bottom of the independent receiving unit 31. This structure allows the overall thickness of the conveying device to be very thin, less than 80mm, thereby reducing the included angle between the rollers. Consequently, while ensuring the same belt wrapping area, the diameter of the rollers can be reduced (for example, the diameter of the driving roller can be reduced to 38mm, and the diameter of the driven roller can be reduced to 32mm), ultimately improving the transition between the front and rear tracks.

[0076] In summary, this utility model of an adjustable-distance X-ray detection device separates the X-ray detector from the main housing of the detection device, making it an independent unit. This allows the X-ray emitter and X-ray detector to be housed in two separate housings. This design not only allows for height adjustment of the X-ray detector but also enables adjustment of the distance between the X-ray detector and the X-ray emitter by vertically adjusting the entire X-ray detector module.

[0077] The X-ray detection device, through the aforementioned structural improvements, can effectively enhance X-ray detection performance and also allows for modular design. When using different X-ray detector combinations, only this module unit needs to be replaced, thus avoiding the need to replace the entire housing.
